commit 104739aca4488909175e9e31d5cd7d75b82a2046 upstream.
If the device is power-cycled, it takes time for the initiator to transmit
the periodic NOTIFY (ENABLE SPINUP) SAS primitive, and for the device to
respond to the primitive to become ACTIVE. Retry the I/O request to allow
the device time to become ACTIVE.

commit 362372ceb6556f338e230f2d90af27b47f82365a upstream.
At extending the available mixer values for 32bit types, we forgot to
add the corresponding entries for the format dump in the proc output.
This may result in OOB access. Here adds the missing entries.

commit 41e81022a04a0294c55cfa7e366bc14b9634c66e upstream.
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the four control requests which erroneously used usb_rcvctrlpipe().

commit ab4a0b8fcb9a95c02909b62049811bd2e586aaa4 upstream.
In ems_usb_disconnect() dev pointer, which is netdev private data, is
used after free_candev() call:
| if (dev) {
| unregister_netdev(dev->netdev);
| free_candev(dev->netdev);
|
| unlink_all_urbs(dev);
|
| usb_free_urb(dev->intr_urb);
|
| kfree(dev->intr_in_buffer);
| kfree(dev->tx_msg_buffer);
| }
Fix it by simply moving free_candev() at the end of the block.

commit 4249d6fbc10fd997abdf8a1ea49c0389a0edf706 upstream.
when receive eem echo command, it will send a response,
but queue this response to the usb request which allocate
from gadget device endpoint zero,
and transmit the request to IN endpoint of eem interface.
on dwc3 gadget, it will trigger following warning in function
__dwc3_gadget_ep_queue(),
if (WARN(req->dep != dep, "request %pK belongs to '%s'\n",
&req->request, req->dep->name))
return -EINVAL;
fix it by allocating a usb request from IN endpoint of eem interface,
and transmit the usb request to same IN endpoint of eem interface.

commit 4897807753e078655a78de39ed76044d784f3e63 upstream.
The device (32a7:0000 Heimann Sensor GmbH USB appset demo) claims to be
a CDC-ACM device in its descriptors but in fact is not. If it is run
with echo disabled it returns garbled data, probably due to something
that happens in the TTY layer. And when run with echo enabled (the
default), it will mess up the calibration data of the sensor the first
time any data is sent to the device.
In short, I had a bad time after connecting the sensor and trying to get
it to work. I hope blacklisting it in the cdc-acm driver will save
someone else a bit of trouble.

commit 84524d1232ecca7cf8678e851b254f05cff4040a upstream.
Creation EP's debugfs called earlier than debugfs folder for dwc3
device created. As result EP's debugfs are created in '/sys/kernel/debug'
instead of '/sys/kernel/debug/usb/dwc3.1.auto'.
Moved dwc3_debugfs_init() function call before calling
dwc3_core_init_mode() to allow create dwc3 debugfs parent before
creating EP's debugfs's.

commit b31d9d6d7abbf6483b871b6370bc31c930d53f54 upstream.
when system is doing s4, the process of xhci_resume may be as below:
1、xhci_mem_cleanup
2、xhci_init->xhci_mem_init->xhci_mem_cleanup(when memory is not enough).
xhci_mem_cleanup will be executed twice when system is out of memory.
xhci->port_caps is freed in xhci_mem_cleanup,but it isn't set to NULL.
It will be freed twice when xhci_mem_cleanup is called the second time.
We got following bug when system resumes from s4:

commit d98e4d95411bbde2220a7afa38dcc9c14d71acbe upstream.
When checking the file name attribute, we want to ensure that it fits
within the bounds of ATTR_RECORD. To do this, we should check that (attr
record + file name offset + file name length) < (attr record + attr record
length).
However, the original check did not include the file name offset in the
calculation. This means that corrupted on-disk metadata might not caught
by the incorrect file name check, and lead to an invalid memory access.
An example can be seen in the crash report of a memory corruption error
found by Syzbot:
https://syzkaller.appspot.com/bug?id=a1a1e379b225812688566745c3e2f7242bffc246
Adding the file name offset to the validity check fixes this error and
passes the Syzbot reproducer test.

From: Alexander Larkin <avlarkin82@gmail.com>
commit f8f84af5da9ee04ef1d271528656dac42a090d00 upstream.
Even though we validate user-provided inputs we then traverse past
validated data when applying the new map. The issue was originally
discovered by Murray McAllister with this simple POC (if the following
is executed by an unprivileged user it will instantly panic the system):
int main(void) {
int fd, ret;
unsigned int buffer[10000];
fd = open("/dev/input/js0", O_RDONLY);
if (fd == -1)
printf("Error opening file\n");
ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
printf("%d\n", ret);
}
The solution is to traverse internal buffer which is guaranteed to only
contain valid date when constructing the map.

commit fdbef8c4e68ad423416aa6cc93d1616d6f8ac5b3 upstream.
Commit 3a95200d3f89 ("arm_pmu: Change API to support 64bit counter values")
changes the input "value" type from 32-bit to 64-bit, which introduces the
following problem: ARMv7 PMU counters is 32-bit width, in big-endian mode,
write counter uses high 32-bit, which writes an incorrect value.
Before:
Performance counter stats for 'ls':
2.22 msec task-clock # 0.675 CPUs utilized
0 context-switches # 0.000 K/sec
0 cpu-migrations # 0.000 K/sec

2147508540 branch-misses # 99.99% of all branches
None of the above hw event counters are correct.
Solution:
"value" forcibly converted to 32-bit type before being written to PMU register.
After:

commit d8ac76cdd1755b21e8c008c28d0b7251c0b14986 upstream.
During an incremental send operation, when processing the new references
for the current inode, we might send an unlink operation for another inode
that has a conflicting path and has more than one hard link. However this
path was computed and cached before we processed previous new references
for the current inode. We may have orphanized a directory of that path
while processing a previous new reference, in which case the path will
be invalid and cause the receiver process to fail.
The following reproducer triggers the problem and explains how/why it
happens in its comments:
$ cat test-send-unlink.sh
#!/bin/bash
DEV=/dev/sdi
MNT=/mnt/sdi
mkfs.btrfs -f $DEV >/dev/null
mount $DEV $MNT
# Create our test files and directory. Inode 259 (file3) has two hard
# links.
touch $MNT/file1
touch $MNT/file2
touch $MNT/file3
mkdir $MNT/A
ln $MNT/file3 $MNT/A/hard_link
# Filesystem looks like:
#
# . (ino 256)
# |----- file1 (ino 257)
# |----- file2 (ino 258)
# |----- file3 (ino 259)
# |----- A/ (ino 260)
# |---- hard_link (ino 259)
#
# Now create the base snapshot, which is going to be the parent snapshot
# for a later incremental send.
btrfs subvolume snapshot -r $MNT $MNT/snap1
btrfs send -f /tmp/snap1.send $MNT/snap1
# Move inode 257 into directory inode 260. This results in computing the
# path for inode 260 as "/A" and caching it.
mv $MNT/file1 $MNT/A/file1
# Move inode 258 (file2) into directory inode 260, with a name of
# "hard_link", moving first inode 259 away since it currently has that
# location and name.
mv $MNT/A/hard_link $MNT/tmp
mv $MNT/file2 $MNT/A/hard_link
# Now rename inode 260 to something else (B for example) and then create
# a hard link for inode 258 that has the old name and location of inode
# 260 ("/A").
mv $MNT/A $MNT/B
ln $MNT/B/hard_link $MNT/A
# Filesystem now looks like:
#
# . (ino 256)
# |----- tmp (ino 259)
# |----- file3 (ino 259)
# |----- B/ (ino 260)
# | |---- file1 (ino 257)
# | |---- hard_link (ino 258)
# |
# |----- A (ino 258)
# Create another snapshot of our subvolume and use it for an incremental
# send.
btrfs subvolume snapshot -r $MNT $MNT/snap2
btrfs send -f /tmp/snap2.send -p $MNT/snap1 $MNT/snap2
# Now unmount the filesystem, create a new one, mount it and try to
# apply both send streams to recreate both snapshots.
umount $DEV
mkfs.btrfs -f $DEV >/dev/null
mount $DEV $MNT
# First add the first snapshot to the new filesystem by applying the
# first send stream.
btrfs receive -f /tmp/snap1.send $MNT
# The incremental receive operation below used to fail with the
# following error:
#
# ERROR: unlink A/hard_link failed: No such file or directory
#
# This is because when send is processing inode 257, it generates the
# path for inode 260 as "/A", since that inode is its parent in the send
# snapshot, and caches that path.
#
# Later when processing inode 258, it first processes its new reference
# that has the path of "/A", which results in orphanizing inode 260
# because there is a a path collision. This results in issuing a rename
# operation from "/A" to "/o260-6-0".
#
# Finally when processing the new reference "B/hard_link" for inode 258,
# it notices that it collides with inode 259 (not yet processed, because
# it has a higher inode number), since that inode has the name
# "hard_link" under the directory inode 260. It also checks that inode
# 259 has two hardlinks, so it decides to issue a unlink operation for
# the name "hard_link" for inode 259. However the path passed to the
# unlink operation is "/A/hard_link", which is incorrect since currently
# "/A" does not exists, due to the orphanization of inode 260 mentioned
# before. The path is incorrect because it was computed and cached
# before the orphanization. This results in the receiver to fail with
# the above error.
btrfs receive -f /tmp/snap2.send $MNT
umount $MNT
When running the test, it fails like this:
$ ./test-send-unlink.sh
Create a readonly snapshot of '/mnt/sdi' in '/mnt/sdi/snap1'
At subvol /mnt/sdi/snap1
Create a readonly snapshot of '/mnt/sdi' in '/mnt/sdi/snap2'
At subvol /mnt/sdi/snap2
At subvol snap1
At snapshot snap2
ERROR: unlink A/hard_link failed: No such file or directory
Fix this by recomputing a path before issuing an unlink operation when
processing the new references for the current inode if we previously
have orphanized a directory.
A test case for fstests will follow soon.

commit 6819703f5a365c95488b07066a8744841bf14231 upstream.
The defrag loop processes leaves in batches and starting transaction for
each. The whole defragmentation on a given root is protected by a bit
but in case the transaction fails, the bit is not cleared
In case the transaction fails the bit would prevent starting
defragmentation again, so make sure it's cleared.

commit b9a037b7f3c401d3c63e0423e56aef606b1ffaaf upstream.
In ext4_orphan_cleanup(), if ext4_truncate() failed to get a transaction
handle, it didn't remove the inode from the in-core orphan list, which
may probably trigger below error dump in ext4_destroy_inode() during the
final iput() and could lead to memory corruption on the later orphan
list changes.

commit e5e7010e5444d923e4091cafff61d05f2d19cada upstream.
After converting fs shrinkers to new scan/count API, we are no longer
pass zero nr_to_scan parameter to detect the number of objects to free,
just remove this check.

commit cd84bbbac12a173a381a64c6ec8b76a5277b87b5 upstream.
Commit 5d1b1b3f492f ("ext4: fix BUG when calling ext4_error with locked
block group") introduces ext4_grp_locked_error to handle unlocking a
group in error cases. Otherwise, there is a possibility of a sleep while
atomic. However, since 43c73221b3b1 ("ext4: replace BUG_ON with WARN_ON
in mb_find_extent()"), mb_find_extent() has contained a ext4_error()
call while a group spinlock is held. Replace this with
ext4_grp_locked_error.

commit d5f9023fa61ee8b94f37a93f08e94b136cf1e463 upstream.
can_rx_register() callbacks may be called concurrently to the call to
can_rx_unregister(). The callbacks and callback data, though, are
protected by RCU and the struct sock reference count.
So the callback data is really attached to the life of sk, meaning
that it should be released on sk_destruct. However, bcm_remove_op()
calls tasklet_kill(), and RCU callbacks may be called under RCU
softirq, so that cannot be used on kernels before the introduction of
HRTIMER_MODE_SOFT.
However, bcm_rx_handler() is called under RCU protection, so after
calling can_rx_unregister(), we may call synchronize_rcu() in order to
wait for any RCU read-side critical sections to finish. That is,
bcm_rx_handler() won't be called anymore for those ops. So, we only
free them, after we do that synchronize_rcu().

commit b17233d385d0b6b43ecf81d43008cb1bbb008166 upstream.
Rather than just indicating that transmission can start, this patch
requires the explicit flushing of the network TX queue when the driver
is informed by the device that it can transmit, next to its
configuration.
In this way, if frames have already been written by the application,
they will actually be transmitted.

commit fcb170a9d825d7db4a3fb870b0300f5a40a8d096 upstream.
The 'queue->nr' will wraparound from 0 to 255 when only current
priority queue has tasks. This maybe lead a deadlock same as commit
dfe1fe75e00e ("NFSv4: Fix deadlock between nfs4_evict_inode()
and nfs4_opendata_get_inode()"):
Privileged delegreturn task is queued to privileged list because all
the slots are assigned. When non-privileged task complete and release
the slot, a non-privileged maybe picked out. It maybe allocate slot
failed when the session on draining.
If the 'queue->nr' has wraparound to 255, and no enough slot to
service it, then the privileged delegreturn will lost to wake up.
So we should avoid the wraparound on 'queue->nr'.

When find a task from wait queue to wake up, a non-privileged task may
be found out, rather than the privileged. This maybe lead a deadlock

Privileged delegreturn task is queued to privileged list because all
the slots are assigned. If there has no enough slot to wake up the
non-privileged batch tasks(session less than 8 slot), then the privileged
delegreturn task maybe lost waked up because the found out task can't
get slot since the session is on draining.
So we should treate the privileged task as the emergency task, and
execute it as for as we can.

commit c749d8c018daf5fba6dfac7b6c5c78b27efd7d65 upstream.
Currently css_wait_for_slow_path() gets called inside the chp->lock.
The path-verification-loop of slowpath inside this lock could lead to
deadlock as reported by the lockdep validator.
The ccw_device_get_chp_desc() during the instance of a device-set-online
would try to acquire the same 'chp->lock' to read the chp->desc.
The instance of this function can get called from multiple scenario,
like probing or setting-device online manually. This could, in some
corner-cases lead to the deadlock.
lockdep validator reported this as,
CPU0 CPU1
---- ----
lock(&chp->lock);
lock(kn->active#43);
lock(&chp->lock);
lock((wq_completion)cio);
The chp->lock was introduced to serialize the access of struct
channel_path. This lock is not needed for the css_wait_for_slow_path()
function, so invoke the slow-path function outside this lock.

commit 950ac33dbe6ff656a623d862022f0762ec061ba7 upstream.
The STM32MP1 RTC may have 2 clocks, the pclk and the rtc_ck.
If clk_prepare_enable() fails for the second clock (rtc_ck) we must only
call clk_disable_unprepare() for the first clock (pclk) but currently we
call it on both leading to a WARN:

commit 7cd04c863f9e1655d607705455e7714f24451984 upstream.
Allocating an IRQ is conditional to the IRQ existence, but freeing it
was not. If no IRQ was allocate, the driver would still try to free
IRQ 0. Add the missing checks.
This fixes the following trace when the driver is removed:
[ 100.667788] Trying to free already-free IRQ 0

commit 2ac0b029a04b673ce83b5089368f467c5dca720c upstream.
The regmap is configured for 8 bit registers, uses a RB-Tree cache and
marks several registers as volatile (i.e. do not cache).
The ALS and PS data registers in the chip are 16 bit wide and spans
two regmap registers. In the current driver only the base register is
marked as volatile, resulting in the upper register only read once.
Further the data sheet notes:
| When the I2C read operation starts, all four ALS data registers are
| locked until the I2C read operation of register 0x8B is completed.
Which results in the registers never update after the 2nd read.
This patch fixes the problem by marking the upper 8 bits of the ALS
and PS registers as volatile, too.

The ltr559 chip uses only the lowest bit of the ALS_CONTR register to
configure between active and stand-by mode. In the original driver
BIT(1) is used, which does a software reset instead.
This patch fixes the problem by using BIT(0) as als_mode_active for
the ltr559 chip.

commit 08a84410a04f05c7c1b8e833f552416d8eb9f6fe upstream.
Stop dmaengine transfer in sci_stop_tx(). Otherwise, the following
message is possible output when system enters suspend and while
transferring data, because clearing TIE bit in SCSCR is not able to
stop any dmaengine transfer.
sh-sci e6550000.serial: ttySC1: Unable to drain transmitter
Note that this driver has already used some #ifdef in the .c file
so that this patch also uses #ifdef to fix the issue. Otherwise,
build errors happens if the CONFIG_SERIAL_SH_SCI_DMA is disabled.

From: Pali Rohár <pali@kernel.org>
commit fb312ac5ccb007e843f982b38d4d6886ba4b32f2 upstream.
I got this crash more times during debugging of PCIe controller and crash
happens somehow at the time when PCIe kernel code started link retraining (as
part of ASPM code) when at the same time PCIe link went down and ath9k probably
executed hw reset procedure.
Currently I'm not able to reproduce this issue as it looks like to be
some race condition between link training, ASPM, link down and reset
path. And as always, race conditions which depends on more input
parameters are hard to reproduce as it depends on precise timings.
But it is clear that pointers are zero in this case and should be
properly filled as same code pattern is used in ath9k_stop() function.
Anyway I was able to reproduce this crash by manually triggering ath
reset worker prior putting card up. I created simple patch to export
reset functionality via debugfs and use it to "simulate" of triggering
reset. s proved that NULL-pointer dereference issue is there.
Function ath9k_hw_reset() is dereferencing chan structure pointer, so it
needs to be non-NULL pointer.
Function ath9k_stop() already contains code which sets ah->curchan to valid
non-NULL pointer prior calling ath9k_hw_reset() function.
Add same code pattern also into ath_reset_internal() function to prevent
kernel NULL pointer dereference in ath9k_hw_reset() function.
This change fixes kernel NULL pointer dereference in ath9k_hw_reset() which
is caused by calling ath9k_hw_reset() from ath_reset_internal() with NULL
chan structure.

It doesn't make sense to clobber the const driver-side buffer, if a
write-to-device attempt failed. All other SSB variants (PCI, PCMCIA and SoC)
also don't corrupt the buffer on any failure in block_write.
Therefore, remove this memset from the SDIO variant.

commit b1c3a24897bd528f2f4fda9fea7da08a84ae25b6 upstream.
The RSI_RATE_x bits must be assigned to struct rsi_data_desc rate_info
field. The rest of the driver does it correctly, except this one place,
so fix it. This is also aligned with the RSI downstream vendor driver.
Without this patch, an AP operating at 5 GHz does not transmit any
beacons at all, this patch fixes that.

commit 314538041b5632ffaf64798faaeabaf2793fe029 upstream.
In AP mode WPA2-PSK connections were not established.
The reason was that the AP was sending the first message
of the 4 way handshake encrypted, even though no pairwise
key had (correctly) yet been set.
Encryption was enabled if the "security_enable" driver flag
was set and encryption was not explicitly disabled by
IEEE80211_TX_INTFL_DONT_ENCRYPT.
However security_enable was set when *any* key, including
the AP GTK key, had been set which was causing unwanted
encryption even if no key was avaialble for the unicast
packet to be sent.
Fix this by adding a check that we have a key and drop
the old security_enable driver flag which is insufficient
and redundant.
The Redpine downstream out of tree driver does it this way too.
Regarding the Fixes tag the actual code being modified was
introduced earlier, with the original driver submission, in
dad0d04fa7ba ("rsi: Add RS9113 wireless driver"), however
at that time AP mode was not yet supported so there was
no bug at that point.
So I have tagged the introduction of AP support instead
which was part of the patch set "rsi: support for AP mode" [1]
It is not clear whether AP WPA has ever worked, I can see nothing
on the kernel side that broke it afterwards yet the AP support
patch series says "Tests are performed to confirm aggregation,
connections in WEP and WPA/WPA2 security."
One possibility is that the initial tests were done with a modified
userspace (hostapd).

commit 26c563731056c3ee66f91106c3078a8c36bb7a9e upstream.
With the addition of simple mathematical operations (plus and minus), the
parsing of the "sym-offset" modifier broke, as it took the '-' part of the
"sym-offset" as a minus, and tried to break it up into a mathematical
operation of "field.sym - offset", in which case it failed to parse
(unless the event had a field called "offset").
Both .sym and .sym-offset modifiers should not be entered into
mathematical calculations anyway. If ".sym-offset" is found in the
modifier, then simply make it not an operation that can be calculated on.

commit 9913d5745bd720c4266805c8d29952a3702e4eca upstream.
All internal use cases for tracepoint_probe_register() is set to not ever
be called with the same function and data. If it is, it is considered a
bug, as that means the accounting of handling tracepoints is corrupted.
If the function and data for a tracepoint is already registered when
tracepoint_probe_register() is called, it will call WARN_ON_ONCE() and
return with EEXISTS.
The BPF system call can end up calling tracepoint_probe_register() with
the same data, which now means that this can trigger the warning because
of a user space process. As WARN_ON_ONCE() should not be called because
user space called a system call with bad data, there needs to be a way to
register a tracepoint without triggering a warning.
Enter tracepoint_probe_register_may_exist(), which can be called, but will
not cause a WARN_ON() if the probe already exists. It will still error out
with EEXIST, which will then be sent to the user space that performed the
BPF system call.
This keeps the previous testing for issues with other users of the
tracepoint code, while letting BPF call it with duplicated data and not
warn about it.

commit 6a2cbc58d6c9d90cd74288cc497c2b45815bc064 upstream.
Since the raw memory 'data' does not go forward, it will dump repeated
data if the data length is more than 8. If we want to dump longer data
blocks, we need to repeatedly call macro SEQ_PUT_HEX_FIELD. I think it
is a bit redundant, and multiple function calls also affect the performance.

From: Michael Ellerman <mpe@ellerman.id.au>
commit 7c6986ade69e3c81bac831645bc72109cd798a80 upstream.
In raise_backtrace_ipi() we iterate through the cpumask of CPUs, sending
each an IPI asking them to do a backtrace, but we don't wait for the
backtrace to happen.
We then iterate through the CPU mask again, and if any CPU hasn't done
the backtrace and cleared itself from the mask, we print a trace on its
behalf, noting that the trace may be "stale".
This works well enough when a CPU is not responding, because in that
case it doesn't receive the IPI and the sending CPU is left to print the
trace. But when all CPUs are responding we are left with a race between
the sending and receiving CPUs, if the sending CPU wins the race then it
will erroneously print a trace.
This leads to spurious "stale" traces from the sending CPU, which can
then be interleaved messily with the receiving CPU, note the CPU
numbers, eg:
[ 1658.929157][ C7] rcu: Stack dump where RCU GP kthread last ran:
[ 1658.929223][ C7] Sending NMI from CPU 7 to CPUs 1:
[ 1658.929303][ C1] NMI backtrace for cpu 1
[ 1658.929303][ C7] CPU 1 didn't respond to backtrace IPI, inspecting paca.
[ 1658.929362][ C1] CPU: 1 PID: 325 Comm: kworker/1:1H Tainted: G W E 5.13.0-rc2+ #46
[ 1658.929405][ C7] irq_soft_mask: 0x01 in_mce: 0 in_nmi: 0 current: 325 (kworker/1:1H)
[ 1658.929465][ C1] Workqueue: events_highpri test_work_fn [test_lockup]
[ 1658.929549][ C7] Back trace of paca->saved_r1 (0xc0000000057fb400) (possibly stale):
[ 1658.929592][ C1] NIP: c00000000002cf50 LR: c008000000820178 CTR: c00000000002cfa0
To fix it, change the logic so that the sending CPU waits 5s for the
receiving CPU to print its trace. If the receiving CPU prints its trace
successfully then the sending CPU just continues, avoiding any spurious
"stale" trace.
This has the added benefit of allowing all CPUs to print their traces in
order and avoids any interleaving of their output.

commit 9eea2904292c2d8fa98df141d3bf7c41ec9dc1b5 upstream.
evm_inode_init_security() requires an HMAC key to calculate the HMAC on
initial xattrs provided by LSMs. However, it checks generically whether a
key has been loaded, including also public keys, which is not correct as
public keys are not suitable to calculate the HMAC.
Originally, support for signature verification was introduced to verify a
possibly immutable initial ram disk, when no new files are created, and to
switch to HMAC for the root filesystem. By that time, an HMAC key should
have been loaded and usable to calculate HMACs for new files.
More recently support for requiring an HMAC key was removed from the
kernel, so that signature verification can be used alone. Since this is a
legitimate use case, evm_inode_init_security() should not return an error
when no HMAC key has been loaded.
This patch fixes this problem by replacing the evm_key_loaded() check with
a check of the EVM_INIT_HMAC flag in evm_initialized.

commit 9acc89d31f0c94c8e573ed61f3e4340bbd526d0c upstream.
EVM_ALLOW_METADATA_WRITES is an EVM initialization flag that can be set to
temporarily disable metadata verification until all xattrs/attrs necessary
to verify an EVM portable signature are copied to the file. This flag is
cleared when EVM is initialized with an HMAC key, to avoid that the HMAC is
calculated on unverified xattrs/attrs.
Currently EVM unnecessarily denies setting this flag if EVM is initialized
with a public key, which is not a concern as it cannot be used to trust
xattrs/attrs updates. This patch removes this limitation.

commit 80ef08670d4c28a06a3de954bd350368780bcfef upstream.
A request could end up on the fpq->io list after fuse_abort_conn() has
reset fpq->connected and aborted requests on that list:
Thread-1 Thread-2
======== ========
->fuse_simple_request() ->shutdown
->__fuse_request_send()
->queue_request() ->fuse_abort_conn()
->fuse_dev_do_read() ->acquire(fpq->lock)
->wait_for(fpq->lock) ->set err to all req's in fpq->io
->release(fpq->lock)
->acquire(fpq->lock)
->add req to fpq->io
After the userspace copy is done the request will be ended, but
req->out.h.error will remain uninitialized. Also the copy might block
despite being already aborted.
Fix both issues by not allowing the request to be queued on the fpq->io
list after fuse_abort_conn() has processed this list.

[ Upstream commit 0e793ba77c18382f08e440260fe72bc6fce2a3cb ]
Currently, the SPI core doesn't set the struct device fwnode pointer
when it creates a new SPI device. This means when the device is
registered the fwnode is NULL and the check in device_add which sets
the fwnode->dev pointer is skipped. This wasn't previously an issue,
however these two patches:
commit 4731210c09f5 ("gpiolib: Bind gpio_device to a driver to enable
fw_devlink=on by default")
commit ced2af419528 ("gpiolib: Don't probe gpio_device if it's not the
primary device")
Added some code to the GPIO core which relies on using that
fwnode->dev pointer to determine if a driver is bound to the fwnode
and if not bind a stub GPIO driver. This means the GPIO providers
behind SPI will get both the expected driver and this stub driver
causing the stub driver to fail if it attempts to request any pin
configuration. For example on my system:
madera-pinctrl madera-pinctrl: pin gpio5 already requested by madera-pinctrl; cannot claim for gpiochip3
madera-pinctrl madera-pinctrl: pin-4 (gpiochip3) status -22
madera-pinctrl madera-pinctrl: could not request pin 4 (gpio5) from group aif1 on device madera-pinctrl
gpio_stub_drv gpiochip3: Error applying setting, reverse things back
gpio_stub_drv: probe of gpiochip3 failed with error -22
The firmware node on the device created by the GPIO framework is set
through the of_node pointer hence things generally actually work,
however that fwnode->dev is never set, as the check was skipped at
device_add time. This fix appears to match how the I2C subsystem
handles the same situation.

[ Upstream commit be8656e62e9e791837b606a027802b504a945c97 ]
syzbot reported leak in cpia2 usb driver. The problem was
in invalid error handling.
v4l2_device_register() is called in cpia2_init_camera_struct(), but
all error cases after cpia2_init_camera_struct() did not call the
v4l2_device_unregister()

[ Upstream commit 3d37ef41bed0854805ab9af22c422267510e1344 ]
The cobalt_s_bit_sysctrl reads the old register value over PCI,
then changes a bit and sets writes the new value to the register.
This is used among other things for setting the HPD output pin.
But if the HPD is changed for multiple inputs at the same time,
then this causes a race condition where a stale value is read.
Serialize this function with a mutex.

[ Upstream commit f8194e5e63fdcb349e8da9eef9e574d5b1d687cb ]
syzbot has reported the following warning in pvr2_i2c_done:
sysfs group 'power' not found for kobject '1-0043'
When the device is disconnected (pvr_hdw_disconnect), the i2c adapter is
not unregistered along with the USB and v4l2 teardown. As part of the USB
device disconnect, the sysfs files of the subdevices are also deleted.
So, by the time pvr_i2c_core_done is called by pvr_context_destroy, the
sysfs files have been deleted.
To fix this, unregister the i2c adapter too in pvr_hdw_disconnect. Make
the device deregistration code shared by calling pvr_hdw_disconnect from
pvr2_hdw_destroy.

[ Upstream commit ac5688637144644f06ed1f3c6d4dd8bb7db96020 ]
The em28xx struct kref isn't being decreased after an error in the
em28xx_ir_init, leading to a possible memory leak.
A kref_put and em28xx_shutdown_buttons is added to the error handler code.

A use after free bug caused by the dangling pointer

See https://lore.kernel.org/patchwork/patch/1419058/.

[ Upstream commit 1a4520090681853e6b850cbe54b27247a013e0e5 ]
In 'bt878_irq', the driver calls 'tasklet_schedule', but this tasklet is
set in 'dvb_bt8xx_load_card' of another driver 'dvb-bt8xx'.
However, this two drivers are separate. The user may not load the
'dvb-bt8xx' driver when loading the 'bt8xx' driver, that is, the tasklet
has not been initialized when 'tasklet_schedule' is called, so it is
necessary to check whether the tasklet is initialized in 'bt878_probe'.
Fix this by adding a check at the end of bt878_probe.
The KASAN's report reveals it:

[ Upstream commit 9ad1efee086e0e913914fa2b2173efb830bad68c ]
When the driver fails to talk with the hardware with dvb_usb_generic_rw,
it will return an error to dvb_usb_adapter_frontend_init. However, the
driver forgets to free the resource (e.g., struct cinergyt2_fe_state),
which leads to a memory leak.
Fix this by freeing struct cinergyt2_fe_state when dvb_usb_generic_rw
fails in cinergyt2_frontend_attach.

[ Upstream commit 45c8ddd06c4b729c56a6083ab311bfbd9643f4a6 ]
Before referencing 'host->data', the driver needs to check whether it is
null pointer, otherwise it will cause a null pointer reference.
This log reveals it:

[ Upstream commit 22ca9f4aaf431a9413dcc115dd590123307f274f ]
crypto_shash_alg_has_setkey() is implemented by testing whether the
.setkey() member of a struct shash_alg points to the default version,
called shash_no_setkey(). As crypto_shash_alg_has_setkey() is a static
inline, this requires shash_no_setkey() to be exported to modules.
Unfortunately, when building with CFI, function pointers are routed
via CFI stubs which are private to each module (or to the kernel proper)
and so this function pointer comparison may fail spuriously.
Let's fix this by turning crypto_shash_alg_has_setkey() into an out of
line function.

[ Upstream commit abc0226df64dc137b48b911c1fe4319aec5891bb ]
The risk of especulation is actually almost-non-existing here,
as there are very few users of TCP/IP using the DVB stack,
as, this is mainly used with DVB-S/S2 cards, and only by people
that receives TCP/IP from satellite connections, which limits
a lot the number of users of such feature(*).
(*) In thesis, DVB-C cards could also benefit from it, but I'm
yet to see a hardware that supports it.
Yet, fixing it is trivial.

[ Upstream commit e198be37e52551bb863d07d2edc535d0932a3c4f ]
Some BT.656 sensors (e.g. ADV718x) transmit frames with unstable BT.656
sync codes after initial power on. This confuses the imx CSI,resulting
in vertical and/or horizontal sync issues. Skip the first 20 frames
to avoid the unstable sync codes.
[fabio: fixed checkpatch warning and increased the frame skipping to 20]

[ Upstream commit bb385bedded3ccbd794559600de4a09448810f4a ]
If we get an error while looking up the inode item we'll simply bail
without cleaning up the delayed node. This results in this style of
warning happening on commit:

Because the iref isn't dropped and this leaves an elevated node->count,
so any release just re-queues it onto the delayed inodes list. Fix this
by going to the out label to handle the proper cleanup of the delayed
node.

[ Upstream commit b05fbcc36be1f8597a1febef4892053a0b2f3f60 ]
With a config having PAGE_SIZE set to 256K, BTRFS build fails
with the following message
include/linux/compiler_types.h:326:38: error: call to
'__compiletime_assert_791' declared with attribute error:
BUILD_BUG_ON failed: (BTRFS_MAX_COMPRESSED % PAGE_SIZE) != 0
BTRFS_MAX_COMPRESSED being 128K, BTRFS cannot support platforms with
256K pages at the time being.
There are two platforms that can select 256K pages:
- hexagon
- powerpc
Disable BTRFS when 256K page size is selected. Supporting this would
require changes to the subpage mode that's currently being developed.
Given that 256K is many times larger than page sizes commonly used and
for what the algorithms and structures have been tuned, it's out of
scope and disabling build is a reasonable option.

[ Upstream commit 65ea8f2c6e230bdf71fed0137cf9e9d1b307db32 ]
Generally, the C-state latency is provided by the _CST method or
FADT, but some OEM platforms using AMD Picasso, Renoir, Van Gogh,
and Cezanne set the C2 latency greater than C3's which causes the
C2 state to be skipped.
That will block the core entering PC6, which prevents S0ix working
properly on Linux systems.
In other operating systems, the latency values are not validated and
this does not cause problems by skipping states.
To avoid this issue on Linux, detect when latencies are not an
arithmetic progression and sort them.

From: Richard Fitzgerald <rf@opensource.cirrus.com>
[ Upstream commit 900fdc4573766dd43b847b4f54bd4a1ee2bc7360 ]
The existing code attempted to handle numbers by doing a strto[u]l(),
ignoring the field width, and then repeatedly dividing to extract the
field out of the full converted value. If the string contains a run of
valid digits longer than will fit in a long or long long, this would
overflow and no amount of dividing can recover the correct value.
This patch fixes vsscanf() to obey number field widths when parsing
the number.
A new _parse_integer_limit() is added that takes a limit for the number
of characters to parse. The number field conversion in vsscanf is changed
to use this new function.
If a number starts with a radix prefix, the field width must be long
enough for at last one digit after the prefix. If not, it will be handled
like this:
sscanf("0x4", "%1i", &i): i=0, scanning continues with the 'x'
sscanf("0x4", "%2i", &i): i=0, scanning continues with the '4'
This is consistent with the observed behaviour of userland sscanf.
Note that this patch does NOT fix the problem of a single field value
overflowing the target type. So for example:
sscanf("123456789abcdef", "%x", &i);
Will not produce the correct result because the value obviously overflows
INT_MAX. But sscanf will report a successful conversion.
Note that where a very large number is used to mean "unlimited", the value
INT_MAX is used for consistency with the behaviour of vsnprintf().

[ Upstream commit 12e0613715e1cf305fffafaf0e89d810d9a85cc0 ]
block_dump is an old debugging interface, one of it's functions is used
to print the information about who write which file on disk. If we
enable block_dump through /proc/sys/vm/block_dump and turn on debug log
level, we can gather information about write process name, target file
name and disk from kernel message. This feature is realized in
block_dump___mark_inode_dirty(), it print above information into kernel
message directly when marking inode dirty, so it is noisy and can easily
trigger log storm. At the same time, get the dentry refcount is also not
safe, we found it will lead to deadlock on ext4 file system with
data=journal mode.
After tracepoints has been introduced into the kernel, we got a
tracepoint in __mark_inode_dirty(), which is a better replacement of
block_dump___mark_inode_dirty(). The only downside is that it only trace
the inode number and not a file name, but it probably doesn't matter
because the original printed file name in block_dump is not accurate in
some cases, and we can still find it through the inode number and device
id. So this patch delete the dirting inode part of block_dump feature.

which worker they are called. Obviously the receive worker cannot cancel
itself and vice versa for swork. For the othercon the receive worker
should only be used, however to avoid deadlocks we should pass the same

[ Upstream commit d327ea15a305024ef0085252fa3657bbb1ce25f5 ]
sparse generates the following warning:
include/linux/prandom.h:114:45: sparse: sparse: cast truncates bits from
constant value
This is because the 64-bit seed value is manipulated and then placed in a
u32, causing an implicit cast and truncation. A forced cast to u32 doesn't
prevent this warning, which is reasonable because a typecast doesn't prove
that truncation was expected.
Logical-AND the value with 0xffffffff to make explicit that truncation to
32-bit is intended.

I got some kmemleak report when a node was fenced. The user space tool
dlm_controld will therefore run some rmdir() in dlm configfs which was
triggering some memleaks. This patch stores the sps and cms attributes
which stores some handling for subdirectories of the configfs cluster
entry and free them if they get released as the parent directory gets
freed.

ACPICA commit 180cb53963aa876c782a6f52cc155d951b26051a
According to the ACPI spec, _CID returns a package containing
hardware ID's. Each element of an ASL package contains a reference
count from the parent package as well as the element itself.
Name (TEST, Package() {
"String object" // this package element has a reference count of 2
})
A memory leak was caused in the _CID repair function because it did
not decrement the reference count created by the package. Fix the
memory leak by calling acpi_ut_remove_reference on _CID package elements
that represent a hardware ID (_HID).

[ Upstream commit db3a34e17433de2390eb80d436970edcebd0ca3e ]
When the clocksource watchdog marks a clock as unstable, this might be due
to that clock being unstable or it might be due to delays that happen to
occur between the reads of the two clocks. Yes, interrupts are disabled
across those two reads, but there are no shortage of things that can delay
interrupts-disabled regions of code ranging from SMI handlers to vCPU
preemption. It would be good to have some indication as to why the clock
was marked unstable.
Therefore, re-read the watchdog clock on either side of the read from the
clock under test. If the watchdog clock shows an excessive time delta
between its pair of reads, the reads are retried.
The maximum number of retries is specified by a new kernel boot parameter
clocksource.max_cswd_read_retries, which defaults to three, that is, up to
four reads, one initial and up to three retries. If more than one retry
was required, a message is printed on the console (the occasional single
retry is expected behavior, especially in guest OSes). If the maximum
number of retries is exceeded, the clock under test will be marked
unstable. However, the probability of this happening due to various sorts
of delays is quite small. In addition, the reason (clock-read delays) for
the unstable marking will be apparent.

A custom DSDT file is mostly used during development or debugging,
and in that case it is quite likely to want to rebuild the kernel
after changing ONLY the content of the DSDT.
This patch adds the custom DSDT as a prerequisite to tables.o
to ensure a rebuild if the DSDT file is updated. Make will merge
the prerequisites from multiple rules for the same target.

[ Upstream commit c5f320ff8a79501bb59338278336ec43acb9d7e2 ]
gcc points out a mistake in the mca driver that goes back to before the
git history:
arch/ia64/kernel/mca_drv.c: In function 'init_record_index_pools':
arch/ia64/kernel/mca_drv.c:346:54: error: expression does not compute the number of elements in this array; element typ
e is 'int', not 'size_t' {aka 'long unsigned int'} [-Werror=sizeof-array-div]
346 | for (i = 1; i < sizeof sal_log_sect_min_sizes/sizeof(size_t); i++)
| ^
This is the same as sizeof(size_t), which is two shorter than the actual
array. Use the ARRAY_SIZE() macro to get the correct calculation instead.

[ Upstream commit 8edcb5049ac29aa3c8acc5ef15dd4036543d747e ]
The use of an enum named 'RST' conflicts with a #define macro
named 'RST' in arch/mips/include/asm/mach-rc32434/rb.h.
The MIPS use of RST was there first (AFAICT), so change the
media/i2c/ uses of RST to be named 'RSET'.
'git grep -w RSET' does not report any naming conflicts with the
new name.
This fixes multiple build errors:

From: Randy Dunlap <rdunlap@infradead.org>
[ Upstream commit 8edcb5049ac29aa3c8acc5ef15dd4036543d747e ]
The use of an enum named 'RST' conflicts with a #define macro
named 'RST' in arch/mips/include/asm/mach-rc32434/rb.h.
The MIPS use of RST was there first (AFAICT), so change the
media/i2c/ uses of RST to be named 'RSET'.
'git grep -w RSET' does not report any naming conflicts with the
new name.
This fixes multiple build errors:
arch/mips/include/asm/mach-rc32434/rb.h:15:14: error: expected identifier before '(' token
15 | #define RST (1 << 15)
| ^
drivers/media/i2c/s5c73m3/s5c73m3.h:356:2: note: in expansion of macro 'RST'
356 | RST,
| ^~~
../arch/mips/include/asm/mach-rc32434/rb.h:15:14: error: expected identifier before '(' token
15 | #define RST (1 << 15)
| ^
../drivers/media/i2c/s5k6aa.c:180:2: note: in expansion of macro 'RST'
180 | RST,
| ^~~
../arch/mips/include/asm/mach-rc32434/rb.h:15:14: error: expected identifier before '(' token

| ^
../drivers/media/i2c/s5k5baf.c:238:2: note: in expansion of macro 'RST'
238 | RST,

and some others that I have trimmed.

[ Upstream commit bfc1f378c8953e68ccdbfe0a8c20748427488b80 ]
Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode
has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler'
parameter being non-NULL if the polling mode is selected. Let's only set
the pointer to the driver's IRQ handler if platform_get_irq() returns a
valid IRQ # -- this should avoid the unnecessary WARN_ON()...

[ Upstream commit 49219d9b8785ba712575c40e48ce0f7461254626 ]
EVM_SETUP_COMPLETE is defined as 0x80000000, which is larger than INT_MAX.
The "-fno-strict-overflow" compiler option properly prevents signaling
EVM that the EVM policy setup is complete. Define and read an unsigned
int.

[ Upstream commit 01fe904c9afd26e79c1f73aa0ca2e3d785e5e319 ]
In isp_video_release, file->private_data is freed via
_vb2_fop_release()->v4l2_fh_release(). But the freed
file->private_data is still used in v4l2_fh_is_singular_file()
->v4l2_fh_is_singular(file->private_data), which is a use
after free bug.
My patch uses a variable 'is_singular_file' to avoid the uaf.

[ Upstream commit 8ed339f23d41e21660a389adf2e7b2966d457ff6 ]
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Control transfers without a data stage are treated as OUT requests by
the USB stack and should be using usb_sndctrlpipe(). Failing to do so
will now trigger a warning.
Fix the gl860_RTx() helper so that zero-length control reads fail with
an error message instead. Note that there are no current callers that
would trigger this.

From: Gustavo A. R. Silva <gustavoars@kernel.org>
[ Upstream commit 13dfead49db07225335d4f587a560a2210391a1a ]
Rename struct sms_msg_data4 to sms_msg_data5 and increase the size of
its msg_data array from 4 to 5 elements. Notice that at some point
the 5th element of msg_data is being accessed in function
smscore_load_firmware_family2():
1006 trigger_msg->msg_data[4] = 4; /* Task ID */
Also, there is no need for the object _trigger_msg_ of type struct
sms_msg_data *, when _msg_ can be used, directly. Notice that msg_data
in struct sms_msg_data is a one-element array, which causes multiple
out-of-bounds warnings when accessing beyond its first element
in function smscore_load_firmware_family2():
992 struct sms_msg_data *trigger_msg =
993 (struct sms_msg_data *) msg;
994
995 pr_debug("sending MSG_SMS_SWDOWNLOAD_TRIGGER_REQ\n");
996 SMS_INIT_MSG(&msg->x_msg_header,
997 MSG_SMS_SWDOWNLOAD_TRIGGER_REQ,
998 sizeof(struct sms_msg_hdr) +
999 sizeof(u32) * 5);
1000
1001 trigger_msg->msg_data[0] = firmware->start_address;
1002 /* Entry point */
1003 trigger_msg->msg_data[1] = 6; /* Priority */
1004 trigger_msg->msg_data[2] = 0x200; /* Stack size */
1005 trigger_msg->msg_data[3] = 0; /* Parameter */
1006 trigger_msg->msg_data[4] = 4; /* Task ID */
even when enough dynamic memory is allocated for _msg_:
929 /* PAGE_SIZE buffer shall be enough and dma aligned */
930 msg = kmalloc(PAGE_SIZE, GFP_KERNEL | coredev->gfp_buf_flags);
but as _msg_ is casted to (struct sms_msg_data *):
992 struct sms_msg_data *trigger_msg =
993 (struct sms_msg_data *) msg;
the out-of-bounds warnings are actually valid and should be addressed.
Fix this by declaring object _msg_ of type struct sms_msg_data5 *,
which contains a 5-elements array, instead of just 4. And use
_msg_ directly, instead of creating object trigger_msg.
This helps with the ongoing efforts to enable -Warray-bounds by fixing
the following warnings:

Fans 7..12 do not have their own set of configuration registers.
So far the code ignored that and read beyond the end of the configuration
register range to get the tachometer period. This resulted in more or less
random fan speed values for those fans.
The datasheet is quite vague when it comes to defining the tachometer
period for fans 7..12. Experiments confirm that the period is the same
for both fans associated with a given set of configuration registers.

When a log recovery is in progress, lots of operations have to take that
into account, so we keep this status per tree during the operation. Long
time ago error handling revamp patch 79787eaab461 ("btrfs: replace many
BUG_ONs with proper error handling") removed clearing of the status in
an error branch. Add it back as was intended in e02119d5a7b4 ("Btrfs:
Add a write ahead tree log to optimize synchronous operations").
There are probably no visible effects, log replay is done only during
mount and if it fails all structures are cleared so the stale status
won't be kept.

[ Upstream commit 0d7993b234c9fad8cb6bec6adfaa74694ba85ecb ]
The current sun6i SPI implementation initializes the transfer too early,
resulting in SCK going high before the transfer. When using an additional
(gpio) chipselect with sun6i, the chipselect is asserted at a time when
clock is high, making the SPI transfer fail.
This is due to SUN6I_GBL_CTL_BUS_ENABLE being written into
SUN6I_GBL_CTL_REG at an early stage. Moving that to the transfer
function, hence, right before the transfer starts, mitigates that
problem.

[ Upstream commit 2a96726bd0ccde4f12b9b9a9f61f7b1ac5af7e10 ]
The function nx842_OF_upd_status triggers a sparse RCU warning when
it directly dereferences the RCU-protected devdata. This appears
to be an accident as there was another variable of the same name
that was passed in from the caller.
After it was removed (because the main purpose of using it, to
update the status member was itself removed) the global variable
unintenionally stood in as its replacement.
This patch restores the devdata parameter.

[ Upstream commit 888be6067b97132c3992866bbcf647572253ab3f ]
Currently, a device description can be obtained using ACPI, if the _STR
method exists for a particular device, and then exposed to the userspace
via a sysfs object as a string value.
If the _STR method is available for a given device then the data
(usually a Unicode string) is read and stored in a buffer (of the
ACPI_TYPE_BUFFER type) with a pointer to said buffer cached in the
struct acpi_device_pnp for later access.
The description_show() function is responsible for exposing the device
description to the userspace via a corresponding sysfs object and
internally calls the utf16s_to_utf8s() function with a pointer to the
buffer that contains the Unicode string so that it can be converted from
UTF16 encoding to UTF8 and thus allowing for the value to be safely
stored and later displayed.
When invoking the utf16s_to_utf8s() function, the description_show()
function also sets a limit of the data that can be saved into a provided
buffer as a result of the character conversion to be a total of
PAGE_SIZE, and upon completion, the utf16s_to_utf8s() function returns
an integer value denoting the number of bytes that have been written
into the provided buffer.
Following the execution of the utf16s_to_utf8s() a newline character
will be added at the end of the resulting buffer so that when the value
is read in the userspace through the sysfs object then it would include
newline making it more accessible when working with the sysfs file
system in the shell, etc. Normally, this wouldn't be a problem, but if
the function utf16s_to_utf8s() happens to return the number of bytes
written to be precisely PAGE_SIZE, then we would overrun the buffer and
write the newline character outside the allotted space which can have
undefined consequences or result in a failure.
To fix this buffer overrun, ensure that there always is enough space
left for the newline character to be safely appended.

[ Upstream commit 1d0903d61e9645c6330b94247b96dd873dfc11c8 ]
Now that we disable wbt by simply zero out rwb->wb_normal in
wbt_disable_default() when switch elevator to bfq, but it's not safe
because it will become false positive if we change queue depth. If it
become false positive between wbt_wait() and wbt_track() when submit
write request, it will lead to drop rqw->inflight to -1 in wbt_done(),
which will end up trigger IO hung. Fix this issue by introduce a new
state which mean the wbt was disabled.

[ Upstream commit 54e948c60cc843b6e84dc44496edc91f51d2a28e ]
The snprintf() function returns the number of bytes which would have been
printed if the buffer was large enough. In other words it can return ">=
remain" but this code assumes it returns "== remain".
The run time impact of this bug is not very severe. The next iteration
through the loop would trigger a WARN() when we pass a negative limit to
snprintf(). We would then return success instead of -E2BIG.
The kernel implementation of snprintf() will never return negatives so
there is no need to check and I have deleted that dead code.

Fix to return -EFAULT from the error handling case instead of 0, as done
elsewhere in this function.
By the way, when get_zeroed_page() fails, directly return -ENOMEM to
simplify code.

[ Upstream commit 272fdc0c4542fad173b44965be02a16d6db95499 ]
kernel test robot reports over 200 build errors and warnings
that are due to this Kconfig problem when CARL9170=m,
MAC80211=y, and LEDS_CLASS=m.
WARNING: unmet direct dependencies detected for MAC80211_LEDS
Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y])
Selected by [m]:
- CARL9170_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && CARL9170 [=m]
CARL9170_LEDS selects MAC80211_LEDS even though its kconfig
dependencies are not met. This happens because 'select' does not follow
any Kconfig dependency chains.
Fix this by making CARL9170_LEDS depend on MAC80211_LEDS, where
the latter supplies any needed dependencies on LEDS_CLASS.

[ Upstream commit ef48667557c53d4b51a1ee3090eab7699324c9de ]
Right now wcn->hal_buf is allocated in wcn36xx_start(). This is a problem
since we should have setup all of the buffers we required by the time
ieee80211_register_hw() is called.
struct ieee80211_ops callbacks may run prior to mac_start() and therefore
wcn->hal_buf must be initialized.
This is easily remediated by moving the allocation to probe() taking the
opportunity to tidy up freeing memory by using devm_kmalloc().

The sinfo->chains field is a bitmask for filled values in chain_signal
and chain_signal_avg, not a count. Treat it as such so that the driver
can properly report per-chain RSSI information.

After (MIMO mode):

The mlx5_ib_bind_slave_port() doesn't remove multiport device from the
unaffiliated list, but mlx5_ib_unbind_slave_port() did it. This unbalanced
flow caused to the situation where mlx5_ib_unaffiliated_port_list was
changed during iteration.

[ Upstream commit 15ae1375ea91ae2dee6f12d71a79d8c0a10a30bf ]
Currently the rdma_rxe driver attempts to protect atomic responder
resources by taking a reference to the qp which is only freed when the
resource is recycled for a new read or atomic operation. This means that
in normal circumstances there is almost always an extra qp reference once
an atomic operation has been executed which prevents cleaning up the qp
and associated pd and cqs when the qp is destroyed.
This patch removes the call to rxe_add_ref() in send_atomic_ack() and the
call to rxe_drop_ref() in free_rd_atomic_resource(). If the qp is
destroyed while a peer is retrying an atomic op it will cause the
operation to fail which is acceptable.

[ Upstream commit 0de449d599594f5472e00267d651615c7f2c6c1d ]
As documented at drivers/base/platform.c for platform_get_irq:
* Gets an IRQ for a platform device and prints an error message if finding the
* IRQ fails. Device drivers should check the return value for errors so as to
* not pass a negative integer value to the request_irq() APIs.
So, the driver should check that platform_get_irq() return value
is _negative_, not that it's equal to zero, because -ENXIO (return
value from request_irq() if irq was not found) will
pass this check and it leads to passing negative irq to request_irq()
Fixes: 0dd077093636 ("NET: Add ezchip ethernet driver")

[ Upstream commit 0cd58e5c53babb9237b741dbef711f0a9eb6d3fd ]
If qfq_change_class() is unable to allocate memory for qfq_aggregate,
it frees the class that has been inserted in the class hash table,
but does not unhash it.
Defer the insertion after the problematic allocation.

When doing source address validation, the flowi4 struct used for
fib_lookup should be in the reverse direction to the given skb.
fl4_dport and fl4_sport returned by fib4_rules_early_flow_dissect
should thus be swapped.

No matter from hwsim_remove or hwsim_del_radio_nl, hwsim_del fails to
remove the entry in the edges list. Take the example below, phy0, phy1
and e0 will be deleted, resulting in e1 not freed and accessed in the
future.

Fix this by deleting and freeing all the entries in the edges list
between hwsim_edge_unsubscribe_me and list_del(&phy->list).

The Broadcom UniMAC MDIO bus from mdio-bcm-unimac module comes too late.
So, GENET cannot find the ethernet PHY on UniMAC MDIO bus. This leads
GENET fail to attach the PHY as following log:

This patch adds the soft dependency to load mdio-bcm-unimac module

I see no reason why max_dst_opts_cnt and max_hbh_opts_cnt
are fetched from the initial net namespace.
The other sysctls (max_dst_opts_len & max_hbh_opts_len)
are in fact already using the current ns.
Note: it is not clear why ipv6_destopt_rcv() use two ways to
get to the netns :
1) dev_net(dst->dev)
Originally used to increment IPSTATS_MIB_INHDRERRORS
2) dev_net(skb->dev)
Tom used this variant in his patch.
Maybe this calls to use ipv6_skb_net() instead ?

[ Upstream commit 364745fbe981a4370f50274475da4675661104df ]
This is technically a backwards incompatible change in behaviour, but I'm
going to argue that it is very unlikely to break things, and likely to fix
*far* more then it breaks.
In no particular order, various reasons follow:
(a) I've long had a bug assigned to myself to debug a super rare kernel crash
on Android Pixel phones which can (per stacktrace) be traced back to BPF clat
IPv6 to IPv4 protocol conversion causing some sort of ugly failure much later
on during transmit deep in the GSO engine, AFAICT precisely because of this
change to gso_size, though I've never been able to manually reproduce it. I
believe it may be related to the particular network offload support of attached
USB ethernet dongle being used for tethering off of an IPv6-only cellular
connection. The reason might be we end up with more segments than max permitted,
or with a GSO packet with only one segment... (either way we break some
assumption and hit a BUG_ON)
(b) There is no check that the gso_size is > 20 when reducing it by 20, so we
might end up with a negative (or underflowing) gso_size or a gso_size of 0.
This can't possibly be good. Indeed this is probably somehow exploitable (or
at least can result in a kernel crash) by delivering crafted packets and perhaps
triggering an infinite loop or a divide by zero... As a reminder: gso_size (MSS)
is related to MTU, but not directly derived from it: gso_size/MSS may be
significantly smaller then one would get by deriving from local MTU. And on
some NICs (which do loose MTU checking on receive, it may even potentially be
larger, for example my work pc with 1500 MTU can receive 1520 byte frames [and
sometimes does due to bugs in a vendor plat46 implementation]). Indeed even just
going from 21 to 1 is potentially problematic because it increases the number
of segments by a factor of 21 (think DoS, or some other crash due to too many
segments).
(c) It's always safe to not increase the gso_size, because it doesn't result in
the max packet size increasing. So the skb_increase_gso_size() call was always
unnecessary for correctness (and outright undesirable, see later). As such the
only part which is potentially dangerous (ie. could cause backwards compatibility
issues) is the removal of the skb_decrease_gso_size() call.
(d) If the packets are ultimately destined to the local device, then there is
absolutely no benefit to playing around with gso_size. It only matters if the
packets will egress the device. ie. we're either forwarding, or transmitting
from the device.
(e) This logic only triggers for packets which are GSO. It does not trigger for
skbs which are not GSO. It will not convert a non-GSO MTU sized packet into a
GSO packet (and you don't even know what the MTU is, so you can't even fix it).
As such your transmit path must *already* be able to handle an MTU 20 bytes
larger then your receive path (for IPv4 to IPv6 translation) - and indeed 28
bytes larger due to IPv4 fragments. Thus removing the skb_decrease_gso_size()
call doesn't actually increase the size of the packets your transmit side must
be able to handle. ie. to handle non-GSO max-MTU packets, the IPv4/IPv6 device/
route MTUs must already be set correctly. Since for example with an IPv4 egress
MTU of 1500, IPv4 to IPv6 translation will already build 1520 byte IPv6 frames,
so you need a 1520 byte device MTU. This means if your IPv6 device's egress
MTU is 1280, your IPv4 route must be 1260 (and actually 1252, because of the
need to handle fragments). This is to handle normal non-GSO packets. Thus the
reduction is simply not needed for GSO packets, because when they're correctly
built, they will already be the right size.
(f) TSO/GSO should be able to exactly undo GRO: the number of packets (TCP
segments) should not be modified, so that TCP's MSS counting works correctly
(this matters for congestion control). If protocol conversion changes the
gso_size, then the number of TCP segments may increase or decrease. Packet loss
after protocol conversion can result in partial loss of MSS segments that the
sender sent. How's the sending TCP stack going to react to receiving ACKs/SACKs
in the middle of the segments it sent?
(g) skb_{decrease,increase}_gso_size() are already no-ops for GSO_BY_FRAGS
case (besides triggering WARN_ON_ONCE). This means you already cannot guarantee
that gso_size (and thus resulting packet MTU) is changed. ie. you must assume
it won't be changed.
(h) changing gso_size is outright buggy for UDP GSO packets, where framing
matters (I believe that's also the case for SCTP, but it's already excluded
by [g]). So the only remaining case is TCP, which also doesn't want it
(see [f]).
(i) see also the reasoning on the previous attempt at fixing this
(commit fa7b83bf3b156c767f3e4a25bbf3817b08f3ff8e) which shows that the current
behaviour causes TCP packet loss:
In the forwarding path GRO -> BPF 6 to 4 -> GSO for TCP traffic, the
coalesced packet payload can be > MSS, but < MSS + 20.
bpf_skb_proto_6_to_4() will upgrade the MSS and it can be > the payload
length. After then tcp_gso_segment checks for the payload length if it
is <= MSS. The condition is causing the packet to be dropped.
tcp_gso_segment():
[...]
mss = skb_shinfo(skb)->gso_size;
if (unlikely(skb->len <= mss)) goto out;
[...]
Thus changing the gso_size is simply a very bad idea. Increasing is unnecessary
and buggy, and decreasing can go negative.

there is more than one byte to parse.
Fix this by taking care of IPV6_TLV_PAD1 before
fetching optlen (under appropriate sanity checks against len)

padding are performed before the check of remaining length.

[ Upstream commit 8b0ed8443ae6458786580d36b7d5f8125535c5d4 ]
The caller of wb_get_create() should pin the memcg, because
wb_get_create() relies on this guarantee. The rcu read lock
only can guarantee that the memcg css returned by css_from_id()
cannot be released, but the reference of the memcg can be zero.
rcu_read_lock()
memcg_css = css_from_id()
wb_get_create(memcg_css)
cgwb_create(memcg_css)
// css_get can change the ref counter from 0 back to 1
css_get(memcg_css)
rcu_read_unlock()
Fix it by holding a reference to the css before calling
wb_get_create(). This is not a problem I encountered in the
real world. Just the result of a code review.

[ Upstream commit fade56410c22cacafb1be9f911a0afd3701d8366 ]
Commit 14972cbd34ff ("net: lwtunnel: Handle fragmentation") moved
fragmentation logic away from lwtunnel by carry encap headroom and
use it in output MTU calculation. But the forwarding part was not
covered and created difference in MTU for output and forwarding and
further to silent drops on ipv4 forwarding path. Fix it by taking
into account lwtunnel encap headroom.
The same commit also introduced difference in how to treat RTAX_MTU
in IPv4 and IPv6 where latter explicitly removes lwtunnel encap
headroom from route MTU. Make IPv4 version do the same.

Syzbot reported warning in tcindex_alloc_perfect_hash. The problem
was in too big cp->hash, which triggers warning in kmalloc. Since
cp->hash comes from userspace, there is no need to warn if value
is not correct

The "dev->port[i].mp.mpi" is set to NULL during mlx5_ib_unbind_slave_port()
execution, however that field is needed to add device to unaffiliated list.
Such flow causes to the following kernel panic while unloading mlx5_ib

prior to unbind call.

A 'request_irq()' call is not balanced by a corresponding 'free_irq()' in
the error handling path, as already done in the remove function.
Add it.

[ Upstream commit 8f4e3d48bb50765ab27ae5bebed2595b20de80a1 ]
A patch from 2017 changed some accesses to DMA memory to use
get_unaligned_le32() and similar interfaces, to avoid problems
with doing unaligned accesson uncached memory.
However, the change in the mwifiex_pcie_alloc_sleep_cookie_buf()
function ended up changing the size of the access instead,
as it operates on a pointer to u8.
Change this function back to actually access the entire 32 bits.
Note that the pointer is aligned by definition because it came
from dma_alloc_coherent().

On an IRQ handler we should not return normal error codes as 'irqreturn_t'
is expected.
Not necessarily stable material as the old check cannot fail, so it's a bug
we can not hit.

Found during an audit of all calls of uses of
iio_push_to_buffers_with_timestamp().
Fixes tag is not strictly accurate as prior to that patch there was
potentially an unaligned write. However, any backport past there will
need to be done manually.

Add __aligned(8) to ensure the buffer passed to
iio_push_to_buffers_with_timestamp() is suitable for the naturally
aligned timestamp that will be inserted.
Here structure is not used, because this buffer is also used
elsewhere in the driver.

commit 06e8f5c842f2d ("ASoC: rsnd: don't call clk_get_rate() under
atomic context") used saved clk_rate, thus for_each_rsnd_clk()
is no longer needed. This patch fixes it.

sccb_mgr_info from si_flags to si_mflags (manager flags) to mend the build.

Currently the cfam_read and cfam_write functions return the provided

code in variable rc, hence all failures of read/writes are being
silently ignored. Fix this by returning the error code in rc.

the driver needs to perform a reset after seeing any of the FSI2PIB
errors, otherwise subsequent operations will also look like failures.

On BMCs with lower timer resolution than 1ms, msleep(1) will take
way longer than 1ms, so looping 10k times won't wait for 10s but
significantly longer.
Fix this by using jiffies like the rest of the code.

[ Upstream commit ce52ec5beecc1079c251f60e3973b3758f60eb59 ]
Commit 1366a3db3dcf ("staging: unisys: visorbus: visorchipset_init clean
up gotos") assigns the initial value -ENODEV to the local variable 'err',
and the first several error branches will return this value after "goto
error". But commit f1f537c2e7f5 ("staging: unisys: visorbus: Consolidate
controlvm channel creation.") overwrites 'err' in the middle of the way.
As a result, some error branches do not successfully return the initial
value -ENODEV of 'err', but return 0.
In addition, when kzalloc() fails, -ENOMEM should be returned instead of
-ENODEV.

[ Upstream commit 5b4f167ef3555ec4c334a8dc89c1b44bb2c6bff5 ]
Driver code call 'devm_of_pci_get_host_bridge_resources'
to get resources and properly fill 'bridge->windows' and
'bridge->dma_ranges'. After parsing the ranges and store
as resources, at the end it makes a call to pci function
'pci_add_resource_offset' to set the offset for the
memory resource. To calculate offset, resource start address
subtracts pci address of the range. MT7621 does not need
any offset for the memory resource. Moreover, setting an
offset got into 'WARN_ON' calls from pci devices driver code.
Until now memory range pci_addr was being '0x00000000' and
res->start is '0x60000000' but becase pci controller driver
was manually setting resources and adding them using pci function
'pci_add_resource' where a zero is passed as offset, things
was properly working. Since PCI_IOBASE is defined now for
ralink we don't set nothing manually anymore so we have to
properly fix PCI address for this range to make things work
and the new pci address must be set to '0x60000000'. Doing
in this way the subtract result obtain zero as offset
and pci device driver code properly works.

[ Upstream commit 78bcae8616ac277d6cb7f38e211493948ed73e30 ]
Support for magic baud rate divisors of 32770 and 32769 used with SMSC
Super I/O chips for extra baud rates of 230400 and 460800 respectively
where base rate is 115200[1] has been added around Linux 2.5.64, which
predates our repo history, but the origin could be identified as commit
2a717aad772f ("Merge with Linux 2.5.64.") with the old MIPS/Linux repo
also at: <git://git.kernel.org/pub/scm/linux/kernel/git/ralf/linux.git>.
Code that is now in `serial8250_do_get_divisor' was added back then to
`serial8250_get_divisor', but that code would only ever trigger if one
of the higher baud rates was actually requested, and that cannot ever
happen, because the earlier call to `serial8250_get_baud_rate' never
returns them. This is because it calls `uart_get_baud_rate' with the
maximum requested being the base rate, that is clk/16 or 115200 for SMSC
chips at their nominal clock rate.
Fix it then and allow UPF_MAGIC_MULTIPLIER baud rates to be selected, by
requesting the maximum baud rate of clk/4 rather than clk/16 if the flag
has been set. Also correct the minimum baud rate, observing that these
ports only support actual (non-magic) divisors of up to 32767 only.

[ Upstream commit 2892d8a00d23d511a0591ac4b2ff3f050ae1f004 ]
Variable "size" has type "phys_addr_t", which can be either 32-bit or
64-bit on 32-bit systems, while "unsigned long" is always 32-bit on
32-bit systems. Hence the cast in
(unsigned long)size / SZ_1M
may truncate a 64-bit size to 32-bit, as casts have a higher operator
precedence than divisions.
Fix this by inverting the order of the cast and division, which should
be safe for memory blocks smaller than 4 PiB. Note that the division is
actually a shift, as SZ_1M is a power-of-two constant, hence there is no
need to use div_u64().
While at it, use "%lu" to format "unsigned long".

currently do not explicitly assign this error code to 'rc'. As a result, 0

When sm5502_init_dev_type() iterates over sm5502_reg_data to
initialize the registers it is limited by ARRAY_SIZE(sm5502_reg_data).
There is no need to add another empty element to sm5502_reg_data.
Having the additional empty element in sm5502_reg_data will just
result in writing 0xff to register 0x00, which does not really
make sense.

printk_safe_flush_on_panic() has special lock breaking code for the case
where we panic()ed with the console lock held. It relies on panic IPI
causing other CPUs to mark themselves offline.
Do as most other architectures do.
This effectively reverts commit de6e5d38417e ("powerpc: smp_send_stop do
not offline stopped CPUs"), unfortunately it may result in some false
positive warnings, but the alternative is more situations where we can
crash without getting messages out.

For default (x16) scheme which is currently used by mvebu-uart.c driver,
maximal divisor of UART base clock is 1023*16. Therefore there is limit for
minimal supported baudrate. This change calculate it correctly and prevents

[ Upstream commit 6a45ece4c9af473555f01f0f8b97eba56e3c7d0d ]
io_remap_pfn_range() will trigger a BUG_ON if it encounters a
populated pte within the mapping range. This can occur because we map
the entire vma on fault and multiple faults can be blocked behind the
vma_lock. This leads to traces like the one reported below.
We can use our vma_list to test whether a given vma is mapped to avoid
this issue.

If other processes are mapping any other subpages of the hugepage, i.e.
in pte-mapped thp case, page_mapcount() will return 1 incorrectly. Then
we would discard the page while other processes are still mapping it. Fix
it by using total_mapcount() which can tell whether other processes are
still mapping it.

[ Upstream commit f36ef407628835a7d7fb3d235b1f1aac7022d9a3 ]
Patch series "selftests/vm/pkeys: Bug fixes and a new test".
There has been a lot of activity on the x86 front around the XSAVE
architecture which is used to context-switch processor state (among other
things). In addition, AMD has recently joined the protection keys club by
adding processor support for PKU.
The AMD implementation helped uncover a kernel bug around the PKRU "init
state", which actually applied to Intel's implementation but was just
harder to hit. This series adds a test which is expected to help find
this class of bug both on AMD and Intel. All the work around pkeys on x86
also uncovered a few bugs in the selftest.
This patch (of 4):
The "random" pkey allocation code currently does the good old:
srand((unsigned int)time(NULL));
*But*, it unfortunately does this on every random pkey allocation.
There may be thousands of these a second. time() has a one second
resolution. So, each time alloc_random_pkey() is called, the PRNG is
*RESET* to time(). This is nasty. Normally, if you do:
srand(<ANYTHING>);
foo = rand();
bar = rand();
You'll be quite guaranteed that 'foo' and 'bar' are different. But, if
you do:
srand(1);
foo = rand();
srand(1);
bar = rand();
You are quite guaranteed that 'foo' and 'bar' are the *SAME*. The recent
"fix" effectively forced the test case to use the same "random" pkey for
the whole test, unless the test run crossed a second boundary.
Only run srand() once at program startup.
This explains some very odd and persistent test failures I've been seeing.

From: Bean Huo <beanhuo@micron.com>
commit 70b52f09080565030a530a784f1c9948a7f48ca3 upstream.
According to the eMMC Spec:
"When command queuing is enabled (CMDQ Mode En bit in CMDQ_MODE_EN
field is set to ‘1’) class 11 commands are the only method through
which data transfer tasks can be issued. Existing data transfer
commands, namely CMD18/CMD17 and CMD25/CMD24, are not supported when
command queuing is enabled."
which means if CMDQ is enabled, the FFU commands will not be supported.
To fix this issue, just simply disable CMDQ on the ioctl path, and
re-enable CMDQ once ioctl request is completed.

Disable all ip's hw status to false before any hw_init.
Only set it to true until its hw_init is executed.
The old 5.9 branch has this change but somehow the 5.11 kernrel does
not have this fix.
Without this change, sriov tdr have gfx IB test fail.

[ Upstream commit 33ae8f801ad8bec48e886d368739feb2816478f2 ]
If multiple threads are accessing the same huge page at the same
time, hugetlb_cow will be called if one thread write the COW huge
page. And function huge_ptep_clear_flush is called to notify other
threads to clear the huge pte tlb entry. The other threads clear
the huge pte tlb entry and reload it from page table, the reload
huge pte entry may be old.
This patch fixes this issue on mips platform, and it clears huge
pte entry before notifying other threads to flush current huge
page entry, it is similar with other architectures.

[ Upstream commit 1c72e6ab66b9598cac741ed397438a52065a8f1f ]
This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

[ Upstream commit 34e7434ba4e97f4b85c1423a59b2922ba7dff2ea ]
This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

[ Upstream commit 8380c81d5c4fced6f4397795a5ae65758272bbfd ]
__napi_schedule_irqoff() is an optimized version of __napi_schedule()
which can be used where it is known that interrupts are disabled,
e.g. in interrupt-handlers, spin_lock_irq() sections or hrtimer
callbacks.
On PREEMPT_RT enabled kernels this assumptions is not true. Force-
threaded interrupt handlers and spinlocks are not disabling interrupts
and the NAPI hrtimer callback is forced into softirq context which runs
with interrupts enabled as well.
Chasing all usage sites of __napi_schedule_irqoff() is a whack-a-mole
game so make __napi_schedule_irqoff() invoke __napi_schedule() for
PREEMPT_RT kernels.
The callers of ____napi_schedule() in the networking core have been
audited and are correct on PREEMPT_RT kernels as well.

syzbot reported divide error in reiserfs.
The problem was in incorrect journal 1st block.
Syzbot's reproducer manualy generated wrong superblock
with incorrect 1st block. In journal_init() wasn't
any checks about this particular case.
For example, if 1st journal block is before superblock
1st block, it can cause zeroing important superblock members
in do_journal_end().

The virtio_gpu_init() will free vgdev and vgdev->vbufs on failure.
But such failure will be caught by virtio_gpu_probe() and then
virtio_gpu_release() will be called to do some cleanup which
will free vgdev and vgdev->vbufs again. So let's set dev->dev_private
to NULL to avoid double free.

In function udf_symlink, epos.bh is assigned with the value returned
by udf_tgetblk. The function udf_tgetblk is defined in udf/misc.c
and returns the value of sb_getblk function that could be NULL.
Then, epos.bh is used without any check, causing a possible
NULL pointer dereference when sb_getblk fails.
This fix adds a check to validate the value of epos.bh.

[ Upstream commit a7196048cd5168096c2c4f44a3939d7a6dcd06b9 ]
The PLLU (USB) consists of the PLL configuration itself and configuration
of the PLLU outputs. The PLLU programming is inconsistent on T30 vs T114,
where T114 immediately bails out if PLLU is enabled and T30 re-enables
a potentially already enabled PLL (left after bootloader) and then fully
reprograms it, which could be unsafe to do. The correct way should be to
skip enabling of the PLL if it's already enabled and then apply
configuration to the outputs. This patch doesn't fix any known problems,
it's a minor improvement.

[ Upstream commit 62f20e068ccc50d6ab66fdb72ba90da2b9418c99 ]
This is a complement to commit aa6dd211e4b1 ("inet: use bigger hash
table for IP ID generation"), but focusing on some specific aspects
of IPv6.
Contary to IPv4, IPv6 only uses packet IDs with fragments, and with a
minimum MTU of 1280, it's much less easy to force a remote peer to
produce many fragments to explore its ID sequence. In addition packet
IDs are 32-bit in IPv6, which further complicates their analysis. On
the other hand, it is often easier to choose among plenty of possible
source addresses and partially work around the bigger hash table the
commit above permits, which leaves IPv6 partially exposed to some
possibilities of remote analysis at the risk of weakening some
protocols like DNS if some IDs can be predicted with a good enough
probability.
Given the wide range of permitted IDs, the risk of collision is extremely
low so there's no need to rely on the positive increment algorithm that
is shared with the IPv4 code via ip_idents_reserve(). We have a fast
PRNG, so let's simply call prandom_u32() and be done with it.
Performance measurements at 10 Gbps couldn't show any difference with
the previous code, even when using a single core, because due to the
large fragments, we're limited to only ~930 kpps at 10 Gbps and the cost
of the random generation is completely offset by other operations and by
the network transfer time. In addition, this change removes the need to
update a shared entry in the idents table so it may even end up being
slightly faster on large scale systems where this matters.
The risk of at least one collision here is about 1/80 million among
10 IDs, 1/850k among 100 IDs, and still only 1/8.5k among 1000 IDs,
which remains very low compared to IPv4 where all IDs are reused
every 4 to 80ms on a 10 Gbps flow depending on packet sizes.

[ Upstream commit 5faafc77f7de69147d1e818026b9a0cbf036a7b2 ]
Current commit code resets the place where the search for free blocks
will begin back to the start of the metadata device. There are a couple
of repercussions to this:
- The first allocation after the commit is likely to take longer than
normal as it searches for a free block in an area that is likely to
have very few free blocks (if any).
- Any free blocks it finds will have been recently freed. Reusing them
means we have fewer old copies of the metadata to aid recovery from
hardware error.
Fix these issues by leaving the cursor alone, only resetting when the
search hits the end of the metadata device.

[ Upstream commit 897120d41e7afd9da435cb00041a142aeeb53c07 ]
Checking value of MCP_INTF in mcp23s08_irq suggests that the handler may be
called even when there is no interrupt pending.
But the actual interrupt could happened between reading MCP_INTF and MCP_GPIO.
In this situation we got nothing from MCP_INTF, but the event gets acknowledged
on the expander by reading MCP_GPIO. This leads to losing events.
Fix the problem by not reading any register until we see something in MCP_INTF.
The error was reproduced and fix tested on MCP23017.

It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.

Based on [1], selinux is tolerate for failure of memory allocation.
Then, use __GFP_NOWARN together.

[ Upstream commit 6fd06963fa74197103cdbb4b494763127b3f2f34 ]
When memory allocation for XFRMA_ENCAP or XFRMA_COADDR fails,
the error will not be reported because the -ENOMEM assignment
to the err variable is overwritten before. Fix this by moving
these two in front of the function so that memory allocation
failures will be reported.

[ Upstream commit 11ef6bc846dcdce838f0b00c5f6a562c57e5d43b ]
At least on wl12xx, reading the MAC after boot can fail with a warning
at drivers/net/wireless/ti/wlcore/sdio.c:78 wl12xx_sdio_raw_read.
The failed call comes from wl12xx_get_mac() that wlcore_nvs_cb() calls
after request_firmware_work_func().
After the error, no wireless interface is created. Reloading the wl12xx
module makes the interface work.
Turns out the wlan controller can be in a low-power ELP state after the
boot from the bootloader or kexec, and needs to be woken up first.
Let's wake the hardware and add a sleep after that similar to
wl12xx_pre_boot() is already doing.
Note that a similar issue could exist for wl18xx, but I have not seen it
so far. And a search for wl18xx_get_mac and wl12xx_sdio_raw_read did not
produce similar errors.

[ Upstream commit ed914d48b6a1040d1039d371b56273d422c0081e ]
This fixes Page Table accounting bug.
MIPS is the ONLY arch just defining __HAVE_ARCH_PMD_ALLOC_ONE alone.
Since commit b2b29d6d011944 (mm: account PMD tables like PTE tables),
"pmd_free" in asm-generic with PMD table accounting and "pmd_alloc_one"
in MIPS without PMD table accounting causes PageTable accounting number
negative, which read by global_zone_page_state(), always returns 0.

[ Upstream commit 6a1e5a4af17e440dd82a58a2c5f40ff17a82b722 ]
When 'nicstar_init_one' fails, 'ns_init_card_error' will be executed for
error handling, but the correct memory free function should be used,
otherwise it will cause an error. Since 'card->rsq.org' and
'card->tsq.org' are allocated using 'dma_alloc_coherent' function, they
should be freed using 'dma_free_coherent'.
Fix this by using 'dma_free_coherent' instead of 'kfree'

[ Upstream commit 70b639dc41ad499384e41e106fce72e36805c9f2 ]
Because the error handling is sequential, the application of resources
should be carried out in the order of error handling, so the operation
of registering the interrupt handler should be put in front, so as not
to free the unregistered interrupt handler during error handling.
This log reveals it:

The client's sk_state will be set to TCP_ESTABLISHED if the server
replay the client's connect request.
However, if the client has pending signal, its sk_state will be set
to TCP_CLOSE without notify the server, so the server will hold the
corrupt connection.
client server
1. sk_state=TCP_SYN_SENT |
2. call ->connect() |
3. wait reply |
| 4. sk_state=TCP_ESTABLISHED
| 5. insert to connected list
| 6. reply to the client
7. sk_state=TCP_ESTABLISHED |
8. insert to connected list |
9. *signal pending* <--------------------- the user kill client
10. sk_state=TCP_CLOSE |
client is exiting... |

if (!(sk->sk_state == TCP_ESTABLISHED ||
sk->sk_state == TCP_CLOSING))
return true; *return at here, the server cannot notice the connection is corrupt*
So the client should notify the peer in this case.

rxe_mr_init_user() always returns the fixed -EINVAL when ib_umem_get()
fails so it's hard for user to know which actual error happens in
ib_umem_get(). For example, ib_umem_get() will return -EOPNOTSUPP when
trying to pin pages on a DAX file.
Return actual error as mlx4/mlx5 does.

[ Upstream commit 8835a64f74c46baebfc946cd5a2c861b866ebcee ]
When we have a P2P Device active, we attempt to only change the
PHY context it uses when we get a new remain-on-channel, if the
P2P Device is the only user of the PHY context.
This is fine if we're switching within a band, but if we're
switching bands then the switch implies a removal and re-add
of the PHY context, which isn't permitted by the firmware while
it's bound to an interface.
Fix the code to skip the unbind/release/... cycle only if the
band doesn't change (or we have old devices that can switch the
band on the fly as well.)

[ Upstream commit 45423cff1db66cf0993e8a9bd0ac93e740149e49 ]
If pci_remove was called for a PF with VFs, the removal of the VFs was
called twice from efx_ef10_sriov_fini: one directly with pci_driver->remove
and another implicit by calling pci_disable_sriov, which also perform
the VFs remove. This was leading to crashing the kernel on the second
attempt.
Given that pci_disable_sriov already calls to pci remove function, get
rid of the direct call to pci_driver->remove from the driver.
2 different ways to trigger the bug:
- Create one or more VFs, then attach the PF to a virtual machine (at
least with qemu/KVM)
- Create one or more VFs, then remove the PF with:
echo 1 > /sys/bus/pci/devices/PF_PCI_ID/remove
Removing sfc module does not trigger the error, at least for me, because
it removes the VF first, and then the PF.
Example of a log with the error:
list_del corruption, ffff967fd20a8ad0->next is LIST_POISON1 (dead000000000100)

Note that this can only happen if any VF is currently attached to a
guest using Xen, but not with vfio/KVM. Despite that in that case the
VFs won't work properly with PF removed and/or the module unloaded, I
have let it as is because I don't know what side effects may have
changing it, and also it seems to be the same that other drivers are
doing in this situation.
In the case of being called during SRIOV reconfiguration, the behavior
hasn't changed because the function is called with force=false.

[ Upstream commit e93bdd78406da9ed01554c51e38b2a02c8ef8025 ]
Fix the following out-of-bounds warning:
net/wireless/wext-spy.c:178:2: warning: 'memcpy' offset [25, 28] from the object at 'threshold' is out of the bounds of referenced subobject 'low' with type 'struct iw_quality' at offset 20 [-Warray-bounds]
The problem is that the original code is trying to copy data into a
couple of struct members adjacent to each other in a single call to
memcpy(). This causes a legitimate compiler warning because memcpy()
overruns the length of &threshold.low and &spydata->spy_thr_low. As
these are just a couple of struct members, fix this by using direct
assignments, instead of memcpy().
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

The syscall bpf(BPF_PROG_QUERY, &attr) should use the prog_cnt field to
see how many entries user space provided and return ENOSPC if there are
more programs than that. Before this patch, this is not checked and
ENOSPC is never returned.
Note that one lirc device is limited to 64 bpf programs, and user space
I'm aware of -- ir-keytable -- always gives enough space for 64 entries
already. However, we should not copy program ids than are requested.

[ Upstream commit 6d123b81ac615072a8525c13c6c41b695270a15d ]
Dave observed number of machines hitting OOM on the UDP send
path. The workload seems to be sending large UDP packets over
loopback. Since loopback has MTU of 64k kernel will try to
allocate an skb with up to 64k of head space. This has a good
chance of failing under memory pressure. What's worse if
the message length is <32k the allocation may trigger an
OOM killer.
This is entirely avoidable, we can use an skb with page frags.
af_unix solves a similar problem by limiting the head
length to SKB_MAX_ALLOC. This seems like a good and simple
approach. It means that UDP messages > 16kB will now
use fragments if underlying device supports SG, if extra
allocator pressure causes regressions in real workloads
we can switch to trying the large allocation first and
falling back.
v4: pre-calculate all the additions to alloclen so
we can be sure it won't go over order-2

This is possible if cma_query_handler() triggers the
RDMA_CM_EVENT_ROUTE_ERROR flow which puts the state machine back and
allows rdma_resolve_route() to be called again.

[ Upstream commit 0c5dc070ff3d6246d22ddd931f23a6266249e3db ]
Ilja reported that, simply putting it, nothing was validating that
from_addr_param functions were operating on initialized memory. That is,
the parameter itself was being validated by sctp_walk_params, but it
doesn't check for types and their specific sizes and it could be a 0-length
one, causing from_addr_param to potentially work over the next parameter or
even uninitialized memory.
The fix here is to, in all calls to from_addr_param, check if enough space
is there for the wanted IP address type.

[ Upstream commit 50619dbf8db77e98d821d615af4f634d08e22698 ]
The first chunk in a packet is ensured to be present at the beginning of
sctp_rcv(), as a packet needs to have at least 1 chunk. But the second
one, may not be completely available and ch->length can be over
uninitialized memory.
Fix here is by only trying to walk on the next chunk if there is enough to
hold at least the header, and then proceed with the ch->length validation
that is already there.

[ Upstream commit c994a3ec7ecc8bd2a837b2061e8a76eb8efc082b ]
Clang's integrated assembler only accepts these instructions when the
cpu is set to mips32r5. With this change, we can assemble
malta_defconfig with Clang via `make LLVM_IAS=1`.

commit 77f30bfcfcf484da7208affd6a9e63406420bf91 upstream.
When initializing a no-key name, fscrypt_fname_disk_to_usr() sets the
minor_hash to 0 if the (major) hash is 0.
This doesn't make sense because 0 is a valid hash code, so we shouldn't
ignore the filesystem-provided minor_hash in that case. Fix this by
removing the special case for 'hash == 0'.
This is an old bug that appears to have originated when the encryption
code in ext4 and f2fs was moved into fs/crypto/. The original ext4 and
f2fs code passed the hash by pointer instead of by value. So
'if (hash)' actually made sense then, as it was checking whether a
pointer was NULL. But now the hashes are passed by value, and
filesystems just pass 0 for any hashes they don't have. There is no
need to handle this any differently from the hashes actually being 0.
It is difficult to reproduce this bug, as it only made a difference in
the case where a filename's 32-bit major hash happened to be 0.
However, it probably had the largest chance of causing problems on
ubifs, since ubifs uses minor_hash to do lookups of no-key names, in
addition to using it as a readdir cookie. ext4 only uses minor_hash as
a readdir cookie, and f2fs doesn't use minor_hash at all.

commit a2b90f11217790ec0964ba9c93a4abb369758c26 upstream.
A removable block device, such as NVMe or SSD connected over Thunderbolt
can be hot-removed any time including when the system is suspended. When
device is hot-removed during suspend and the system gets resumed, kernel
first resumes devices and then thaws the userspace including freezable
workqueues. What happens in that case is that the NVMe driver notices
that the device is unplugged and removes it from the system. This ends
up calling bdi_unregister() for the gendisk which then schedules
wb_workfn() to be run one more time.
However, since the bdi_wq is still frozen flush_delayed_work() call in
wb_shutdown() blocks forever halting system resume process. User sees
this as hang as nothing is happening anymore.
Triggering sysrq-w reveals this:
Workqueue: nvme-wq nvme_remove_dead_ctrl_work [nvme]
Call Trace:

This is not limited to NVMes so exactly same issue can be reproduced by
hot-removing SSD (over Thunderbolt) while the system is suspended.
Prevent this from happening by removing WQ_FREEZABLE from bdi_wq.

The current comment in ->set_baud_rate() is rather incomplete as it
fails to describe what are the actual stages for the baudrate
derivation. Replace this comment with something more explicit and
close to the functional specification. Also adapt the variable names
to it.

commit 015d98149b326e0f1f02e44413112ca8b4330543 upstream.
A change in clang 13 results in the __lwsync macro being defined as
__builtin_ppc_lwsync, which emits 'lwsync' or 'msync' depending on what
the target supports. This breaks the build because of -Werror in
arch/powerpc, along with thousands of warnings:

Undefine this macro so that the runtime patching introduced by

work properly with clang and the build no longer breaks.

commit ecfbd7b9054bddb12cea07fda41bb3a79a7b0149 upstream.
FunctionFS device structure 'struct ffs_dev' and driver data structure
'struct ffs_data' are bound to each other with cross-reference pointers
'ffs_data->private_data' and 'ffs_dev->ffs_data'. While the first one
is supposed to be valid through the whole life of 'struct ffs_data'
(and while 'struct ffs_dev' exists non-freed), the second one is cleared
in 'ffs_closed()' (called from 'ffs_data_reset()' or the last
'ffs_data_put()'). This can be called several times, alternating in
different order with 'ffs_free_inst()', that, if possible, clears
the other cross-reference.
As a result, different cases of these calls order may leave stale
cross-reference pointers, used when the pointed structure is already
freed. Even if it occasionally doesn't cause kernel crash, this error
is reported by KASAN-enabled kernel configuration.
For example, the case [last 'ffs_data_put()' - 'ffs_free_inst()'] was
fixed by commit cdafb6d8b8da ("usb: gadget: f_fs: Fix use-after-free in
ffs_free_inst").
The other case ['ffs_data_reset()' - 'ffs_free_inst()' - 'ffs_data_put()']
now causes KASAN reported error [1], when 'ffs_data_reset()' clears
'ffs_dev->ffs_data', then 'ffs_free_inst()' frees the 'struct ffs_dev',
but can't clear 'ffs_data->private_data', which is then accessed
in 'ffs_closed()' called from 'ffs_data_put()'. This happens since
'ffs_dev->ffs_data' reference is cleared too early.
Moreover, one more use case, when 'ffs_free_inst()' is called immediately
after mounting FunctionFS device (that is before the descriptors are
written and 'ffs_ready()' is called), and then 'ffs_data_reset()'
or 'ffs_data_put()' is called from accessing "ep0" file or unmounting
the device. This causes KASAN error report like [2], since
'ffs_dev->ffs_data' is not yet set when 'ffs_free_inst()' can't properly
clear 'ffs_data->private_data', that is later accessed to freed structure.
Fix these (and may be other) cases of stale pointers access by moving
setting and clearing of the mentioned cross-references to the single
places, setting both of them when 'struct ffs_data' is created and
bound to 'struct ffs_dev', and clearing both of them when one of the
structures is destroyed. It seems convenient to make this pointer
initialization and structures binding in 'ffs_acquire_dev()' and
make pointers clearing in 'ffs_release_dev()'. This required some
changes in these functions parameters and return types.
Also, 'ffs_release_dev()' calling requires some cleanup, fixing minor
issues, like (1) 'ffs_release_dev()' is not called if 'ffs_free_inst()'
is called without unmounting the device, and "release_dev" callback
is not called at all, or (2) "release_dev" callback is called before
"ffs_closed" callback on unmounting, which seems to be not correctly
nested with "acquire_dev" and "ffs_ready" callbacks.
Make this cleanup togther with other mentioned 'ffs_release_dev()' changes.

commit 1ca46d3e43569186bd1decfb02a6b4c4ddb4304b upstream.
Add device HID AMDI0031 to the AMD GPIO controller driver match table.
This controller can be found on Microsoft Surface Laptop 4 devices and
seems similar enough that we can just copy the existing AMDI0030 entry.

commit 35cbb8c91e9cf310277d3dfb4d046df8edf2df33 upstream.
Setting the cap without the modifier list is very confusing to
userspace. Fix that by listing the ones we support explicitly.
Stable backport so that userspace can rely on this working in a
reasonable way, i.e. that the cap set implies IN_FORMATS is available.

commit d0244847f9fc5e20df8b7483c8a4717fe0432d38 upstream.
When an eMMC device is being run in HS400 mode, any access to the
RPMB device will cause the error message "mmc1: Invalid UHS-I mode
selected". This happens as a result of tuning being disabled before
RPMB access and then re-enabled after the RPMB access is complete.
When tuning is re-enabled, the system has to switch from HS400
to HS200 to do the tuning and then back to HS400. As part of
sequence to switch from HS400 to HS200 the system is temporarily
put into HS mode. When switching to HS mode, sdhci_get_preset_value()
is called and does not have support for HS mode and prints the warning
message and returns the preset for SDR12. The fix is to add support
for MMC and SD HS modes to sdhci_get_preset_value().
This can be reproduced on any system running eMMC in HS400 mode
(not HS400ES) by using the "mmc" utility to run the following
command: "mmc rpmb read-counter /dev/mmcblk0rpmb".

commit 77347eda64ed5c9383961d1de9165f9d0b7d8df6 upstream.
It might be that something goes wrong during tuning so the MMC core will
immediately trigger a retune. In our case it was:
- we sent a tuning block
- there was an error so we need to send an abort cmd to the eMMC
- the abort cmd had a CRC error
- retune was set by the MMC core
This lead to a vicious circle causing a performance regression of 75%.
So, clear retuning flags before we enable retuning to start with a known
cleared state.

From: Christian Löhle <CLoehle@hyperstone.com>
commit 09247e110b2efce3a104e57e887c373e0a57a412 upstream.
While initializing an UHS-I SD card, the mmc core first tries to switch to
1.8V I/O voltage, before it continues to change the settings for the bus
speed mode.
However, the current behaviour in the mmc core is inconsistent and doesn't
conform to the SD spec. More precisely, an SD card that supports UHS-I must
set both the SD_OCR_CCS bit and the SD_OCR_S18R bit in the OCR register
response. When switching to 1.8V I/O the mmc core correctly checks both of
the bits, but only the SD_OCR_S18R bit when changing the settings for bus
speed mode.
Rather than actually fixing the code to confirm to the SD spec, let's
deliberately deviate from it by requiring only the SD_OCR_S18R bit for both
parts. This enables us to support UHS-I for SDSC cards (outside spec),
which is actually being supported by some existing SDSC cards. Moreover,
this fixes the inconsistent behaviour.

commit f6bca4d91b2ea052e917cca3f9d866b5cc1d500a upstream.
DIPM is unsupported or broken on sunxi. Trying to enable the power
management policy med_power_with_dipm on an Allwinner A20 SoC based board
leads to immediate I/O errors and the attached SATA disk disappears from
the /dev filesystem. A reset (power cycle) is required to make the SATA
controller or disk work again. The A10 and A20 SoC data sheets and manuals
don't mention DIPM at all [1], so it's fair to assume that it's simply not
supported. But even if it was, it should be considered broken and best be
disabled in the ahci_sunxi driver.

From: Thomas Gleixner <tglx@linutronix.de>
commit b22afcdf04c96ca58327784e280e10288cfd3303 upstream.
Alexey and Joshua tried to solve a cpusets related hotplug problem which is
user space visible and results in unexpected behaviour for some time after
a CPU has been plugged in and the corresponding uevent was delivered.
cpusets delegate the hotplug work (rebuilding cpumasks etc.) to a
workqueue. This is done because the cpusets code has already a lock
nesting of cgroups_mutex -> cpu_hotplug_lock. A synchronous callback or
waiting for the work to finish with cpu_hotplug_lock held can and will
deadlock because that results in the reverse lock order.
As a consequence the uevent can be delivered before cpusets have consistent
state which means that a user space invocation of sched_setaffinity() to
move a task to the plugged CPU fails up to the point where the scheduled
work has been processed.
The same is true for CPU unplug, but that does not create user observable
failure (yet).
It's still inconsistent to claim that an operation is finished before it
actually is and that's the real issue at hand. uevents just make it
reliably observable.
Obviously the problem should be fixed in cpusets/cgroups, but untangling
that is pretty much impossible because according to the changelog of the
commit which introduced this 8 years ago:
3a5a6d0c2b03("cpuset: don't nest cgroup_mutex inside get_online_cpus()")
the lock order cgroups_mutex -> cpu_hotplug_lock is a design decision and
the whole code is built around that.
So bite the bullet and invoke the relevant cpuset function, which waits for
the work to finish, in _cpu_up/down() after dropping cpu_hotplug_lock and
only when tasks are not frozen by suspend/hibernate because that would
obviously wait forever.
Waiting there with cpu_add_remove_lock, which is protecting the present
and possible CPU maps, held is not a problem at all because neither work
queues nor cpusets/cgroups have any lockchains related to that lock.
Waiting in the hotplug machinery is not problematic either because there
are already state callbacks which wait for hardware queues to drain. It
makes the operations slightly slower, but hotplug is slow anyway.
This ensures that state is consistent before returning from a hotplug
up/down operation. It's still inconsistent during the operation, but that's
a different story.
Add a large comment which explains why this is done and why this is not a
dump ground for the hack of the day to work around half thought out locking
schemes. Document also the implications vs. hotplug operations and
serialization or the lack of it.
Thanks to Alexy and Joshua for analyzing why this temporary
sched_setaffinity() failure happened.

commit 8b33dfe0ba1c84c1aab2456590b38195837f1e6e upstream.
Bad counter reads are experienced sometimes when bit 10 or greater rolls
over. Originally, testing showed that at least 10 lower bits would be
set to the same value during these bad reads. However, some users still
reported time skips.
Wider testing revealed that on some chips, occasionally only the lowest
9 bits would read as the anomalous value. During these reads (which
still happen only when bit 10), bit 9 would read as the correct value.
Reduce the mask by one bit to cover these cases as well.

commit f6eb84fa596abf28959fc7e0b626f925eb1196c7 upstream.
The driver_name="tegra" is now required by the newer ALSA UCMs, otherwise
Tegra UCMs don't match by the path/name.
All Tegra machine drivers are specifying the card's name, but it has no
effect if model name is specified in the device-tree since it overrides
the card's name. We need to set the driver_name to "tegra" in order to
get a usable lookup path for the updated ALSA UCMs. The new UCM lookup
path has a form of driver_name/card_name.
The old lookup paths that are based on driver module name continue to
work as before. Note that UCM matching never worked for Tegra ASoC drivers
if they were compiled as built-in, this is fixed by supporting the new
naming scheme.

commit fca41af18e10318e4de090db47d9fa7169e1bf2f upstream.
fw_cfg_showrev() is called by an indirect call in kobj_attr_show(),
which violates clang's CFI checking because fw_cfg_showrev()'s second
parameter is 'struct attribute', whereas the ->show() member of 'struct
kobj_structure' expects the second parameter to be of type 'struct
kobj_attribute'.
$ cat /sys/firmware/qemu_fw_cfg/rev
3
$ dmesg | grep "CFI failure"
[ 26.016832] CFI failure (target: fw_cfg_showrev+0x0/0x8):
Fix this by converting fw_cfg_rev_attr to 'struct kobj_attribute' where
this would have been caught automatically by the incompatible pointer
types compiler warning. Update fw_cfg_showrev() accordingly.

From: Petr Pavlu <petr.pavlu@suse.com>
commit 2253042d86f57d90a621ac2513a7a7a13afcf809 upstream.
When an IPMI watchdog timer is being stopped in ipmi_close() or
ipmi_ioctl(WDIOS_DISABLECARD), the current watchdog action is updated to
WDOG_TIMEOUT_NONE and _ipmi_set_timeout(IPMI_SET_TIMEOUT_NO_HB) is called
to install this action. The latter function ends up invoking
__ipmi_set_timeout() which makes the actual 'Set Watchdog Timer' IPMI
request.
For IPMI 1.0, this operation results in fully stopping the watchdog timer.
For IPMI >= 1.5, function __ipmi_set_timeout() always specifies the "don't
stop" flag in the prepared 'Set Watchdog Timer' IPMI request. This causes
that the watchdog timer has its action correctly updated to 'none' but the
timer continues to run. A problem is that IPMI firmware can then still log
an expiration event when the configured timeout is reached, which is
unexpected because the watchdog timer was requested to be stopped.
The patch fixes this problem by not setting the "don't stop" flag in
__ipmi_set_timeout() when the current action is WDOG_TIMEOUT_NONE which
results in stopping the watchdog timer. This makes the behaviour for
IPMI >= 1.5 consistent with IPMI 1.0. It also matches the logic in
__ipmi_heartbeat() which does not allow to reset the watchdog if the
current action is WDOG_TIMEOUT_NONE as that would start the timer.

Trying to get the AB8500 charging driver working I ran into a bit
of bitrot: we haven't used the driver for a while so errors in
refactorings won't be noticed.
This one is pretty self evident: use argument to the macro or we
end up with a random pointer to something else.

commit d3b16034a24a112bb83aeb669ac5b9b01f744bb7 upstream.
There's two variables being increased in that loop (i and j), and i
follows the raw data, and j follows what is being written into the buffer.
We should compare 'i' to MAX_MEMHEX_BYTES or compare 'j' to HEX_CHARS.
Otherwise, if 'j' goes bigger than HEX_CHARS, it will overflow the
destination buffer.

commit b81b3e959adb107cd5b36c7dc5ba1364bbd31eb2 upstream.
The tgid_map array records a mapping from pid to tgid, where the index
of an entry within the array is the pid & the value stored at that index
is the tgid.
The saved_tgids_next() function iterates over pointers into the tgid_map
array & dereferences the pointers which results in the tgid, but then it
passes that dereferenced value to trace_find_tgid() which treats it as a
pid & does a further lookup within the tgid_map array. It seems likely
that the intent here was to skip over entries in tgid_map for which the
recorded tgid is zero, but instead we end up skipping over entries for
which the thread group leader hasn't yet had its own tgid recorded in
tgid_map.
A minimal fix would be to remove the call to trace_find_tgid, turning:
if (trace_find_tgid(*ptr))
into:
if (*ptr)
..but it seems like this logic can be much simpler if we simply let
seq_read() iterate over the whole tgid_map array & filter out empty
entries by returning SEQ_SKIP from saved_tgids_show(). Here we take that
approach, removing the incorrect logic here entirely.

commit 4030a6e6a6a4a42ff8c18414c9e0c93e24cc70b8 upstream.
Currently tgid_map is sized at PID_MAX_DEFAULT entries, which means that
on systems where pid_max is configured higher than PID_MAX_DEFAULT the
ftrace record-tgid option doesn't work so well. Any tasks with PIDs
higher than PID_MAX_DEFAULT are simply not recorded in tgid_map, and
don't show up in the saved_tgids file.
In particular since systemd v243 & above configure pid_max to its
highest possible 1<<22 value by default on 64 bit systems this renders
the record-tgids option of little use.
Increase the size of tgid_map to the configured pid_max instead,
allowing it to cover the full range of PIDs up to the maximum value of
PID_MAX_LIMIT if the system is configured that way.
On 64 bit systems with pid_max == PID_MAX_LIMIT this will increase the
size of tgid_map from 256KiB to 16MiB. Whilst this 64x increase in
memory overhead sounds significant 64 bit systems are presumably best
placed to accommodate it, and since tgid_map is only allocated when the
record-tgid option is actually used presumably the user would rather it
spends sufficient memory to actually record the tgids they expect.
The size of tgid_map could also increase for CONFIG_BASE_SMALL=y
configurations, but these seem unlikely to be systems upon which people
are both configuring a large pid_max and running ftrace with record-tgid
anyway.
Of note is that we only allocate tgid_map once, the first time that the
record-tgid option is enabled. Therefore its size is only set once, to
the value of pid_max at the time the record-tgid option is first
enabled. If a user increases pid_max after that point, the saved_tgids
file will not contain entries for any tasks with pids beyond the earlier
value of pid_max.

commit 9272e5d0028d45a3b45b58c9255e6e0df53f7ad9 upstream.
In the out_err_bus_register error branch of tpci200_pci_probe,
tpci200->info->cfg_regs is freed by tpci200_uninstall()->
tpci200_unregister()->pci_iounmap(..,tpci200->info->cfg_regs)
in the first time.
But later, iounmap() is called to free tpci200->info->cfg_regs
again.
My patch sets tpci200->info->cfg_regs to NULL after tpci200_uninstall()
to avoid the double free.

commit 5fae8a946ac2df879caf3f79a193d4766d00239b upstream.
commit 6f755e85c332 ("coresight: Add helper for inserting synchronization
packets") removed trailing '\0' from barrier_pkt array and updated the
call sites like etb_update_buffer() to have proper checks for barrier_pkt
size before read but missed updating tmc_update_etf_buffer() which still
reads barrier_pkt past the array size resulting in KASAN out-of-bounds
bug. Fix this by adding a check for barrier_pkt size before accessing
like it is done in etb_update_buffer().

remove_raw() in dm_btree_remove() may fail due to IO read error
(e.g. read the content of origin block fails during shadowing),
and the value of shadow_spine::root is uninitialized, but
the uninitialized value is still assign to new_root in the
end of dm_btree_remove().
For dm-thin, the value of pmd->details_root or pmd->root will become
an uninitialized value, so if trying to read details_info tree again
out-of-bound memory may occur as showed below:

commit 4694ae373dc2114f9a82f6ae15737e65af0c6dea upstream.
On Macbook 2013, resuming from suspend-to-idle or standby resulted in the
external monitor no longer being detected, a stacktrace, and errors like
this in dmesg:
pcieport 0000:06:00.0: can't change power state from D3hot to D0 (config space inaccessible)
The reason is that we know how to turn power to the Thunderbolt controller
*off* via the SXIO/SXFP/SXLF methods, but we don't know how to turn power
back on. We have to rely on firmware to turn the power back on.
When going to the "suspend-to-idle" or "standby" system sleep states,
firmware is not involved either on the suspend side or the resume side, so
we can't use SXIO/SXFP/SXLF to turn the power off.
Skip SXIO/SXFP/SXLF when firmware isn't involved in suspend, e.g., when
we're going to the "suspend-to-idle" or "standby" system sleep states.

commit 8ceeac307a79f68c0d0c72d6e48b82fa424204ec upstream.
PIO_NON_POSTED_REQ for PIO_STAT register is incorrectly defined. Bit 10 in
register PIO_STAT indicates the response is to a non-posted request.

From: Arnd Bergmann <arnd@arndb.de>
commit 0a7790be182d32b9b332a37cb4206e24fe94b728 upstream.
The saa6588_ioctl() function expects to get called from other kernel
functions with a 'saa6588_command' pointer, but I found nothing stops it
from getting called from user space instead, which seems rather dangerous.
The same thing happens in the davinci vpbe driver with its VENC_GET_FLD
command.
As a quick fix, add a separate .command() callback pointer for this
driver and change the two callers over to that. This change can easily
get backported to stable kernels if necessary, but since there are only
two drivers, we may want to eventually replace this with a set of more
specialized callbacks in the long run.

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Control transfers without a data stage are treated as OUT requests by
the USB stack and should be using usb_sndctrlpipe(). Failing to do so
will now trigger a warning.
Fix the single zero-length control request which was using the
read-register helper, and update the helper so that zero-length reads
fail with an error message instead.

commit 4c6e0976295add7f0ed94d276c04a3d6f1ea8f83 upstream.
The Elgato Cam Link 4K HDMI video capture card reports to support three
different pixel formats, where the first format depends on the connected
HDMI device.
```
$ v4l2-ctl -d /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture
[0]: 'NV12' (Y/CbCr 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
[1]: 'NV12' (Y/CbCr 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
[2]: 'YU12' (Planar YUV 4:2:0)
Size: Discrete 3840x2160
Interval: Discrete 0.033s (29.970 fps)
```
Changing the pixel format to anything besides the first pixel format
does not work:
```
$ v4l2-ctl -d /dev/video0 --try-fmt-video pixelformat=YU12
Format Video Capture:
Width/Height : 3840/2160
Pixel Format : 'NV12' (Y/CbCr 4:2:0)
Field : None
Bytes per Line : 3840
Size Image : 12441600
Colorspace : sRGB
Transfer Function : Rec. 709
YCbCr/HSV Encoding: Rec. 709
Quantization : Default (maps to Limited Range)
Flags :
```
User space applications like VLC might show an error message on the
terminal in that case:
```
libv4l2: error set_fmt gave us a different result than try_fmt!
```
Depending on the error handling of the user space applications, they
might display a distorted video, because they use the wrong pixel format
for decoding the stream.
The Elgato Cam Link 4K responds to the USB video probe
VS_PROBE_CONTROL/VS_COMMIT_CONTROL with a malformed data structure: The
second byte contains bFormatIndex (instead of being the second byte of
bmHint). The first byte is always zero. The third byte is always 1.
The firmware bug was reported to Elgato on 2020-12-01 and it was
forwarded by the support team to the developers as feature request.
There is no firmware update available since then. The latest firmware
for Elgato Cam Link 4K as of 2021-03-23 has MCU 20.02.19 and FPGA 67.
Therefore correct the malformed data structure for this device. The
change was successfully tested with VLC, OBS, and Chromium using
different pixel formats (YUYV, NV12, YU12), resolutions (3840x2160,
1920x1080), and frame rates (29.970 and 59.940 fps).

commit f85d40160691881a17a397c448d799dfc90987ba upstream.
When the host is using debug registers but the guest is not using them
nor is the guest in guest-debug state, the kvm code does not reset
the host debug registers before kvm_x86->run(). Rather, it relies on
the hardware vmentry instruction to automatically reset the dr7 registers
which ensures that the host breakpoints do not affect the guest.
This however violates the non-instrumentable nature around VM entry
and exit; for example, when a host breakpoint is set on vcpu->arch.cr2,
Another issue is consistency. When the guest debug registers are active,
the host breakpoints are reset before kvm_x86->run(). But when the
guest debug registers are inactive, the host breakpoints are delayed to
be disabled. The host tracing tools may see different results depending
on what the guest is doing.
To fix the problems, we clear %db7 unconditionally before kvm_x86->run()
if the host has set any breakpoints, no matter if the guest is using
them or not.

commit 93aa71ad7379900e61c8adff6a710a4c18c7c99b upstream.
Commit 66a834d09293 ("scsi: core: Fix error handling of scsi_host_alloc()")
changed the allocation logic to call put_device() to perform host cleanup
with the assumption that IDA removal and stopping the kthread would
properly be performed in scsi_host_dev_release(). However, in the unlikely
case that the error handler thread fails to spawn, shost->ehandler is set
to ERR_PTR(-ENOMEM).
The error handler cleanup code in scsi_host_dev_release() will call
kthread_stop() if shost->ehandler != NULL which will always be the case
whether the kthread was successfully spawned or not. In the case that it
failed to spawn this has the nasty side effect of trying to dereference an
invalid pointer when kthread_stop() is called. The following splat provides
an example of this behavior in the wild:

commit 704adfb5a9978462cd861f170201ae2b5e3d3a80 upstream.
The histogram logic was allowing events with char * pointers to be used as
normal strings. But it was easy to crash the kernel with:
# echo 'hist:keys=filename' > events/syscalls/sys_enter_openat/trigger
And open some files, and boom!

Where it triggered a fault on strlen(key) where key was the filename.
The reason is that filename is a char * to user space, and the histogram
code just blindly dereferenced it, with obvious bad results.
I originally tried to use strncpy_from_user/kernel_nofault() but found
that there's other places that its dereferenced and not worth the effort.
Just do not allow "char *" to act like strings.

commit 7fbcb5da811be7d47468417c7795405058abb3da upstream.
advk_pcie_wait_pio() can be called while holding a spinlock (from
pci_bus_read_config_dword()), then depends on jiffies in order to
timeout while polling on PIO state registers. In the case the PIO
transaction failed, the timeout will never happen and will also cause
the cpu to stall.
This decrements a variable and wait instead of using jiffies.

commit f18139966d072dab8e4398c95ce955a9742e04f7 upstream.
Trying to start a new PIO transfer by writing value 0 in PIO_START register
when previous transfer has not yet completed (which is indicated by value 1
in PIO_START) causes an External Abort on CPU, which results in kernel
panic:
SError Interrupt on CPU0, code 0xbf000002 -- SError
Kernel panic - not syncing: Asynchronous SError Interrupt
To prevent kernel panic, it is required to reject a new PIO transfer when
previous one has not finished yet.
If previous PIO transfer is not finished yet, the kernel may issue a new
PIO request only if the previous PIO transfer timed out.
In the past the root cause of this issue was incorrectly identified (as it
often happens during link retraining or after link down event) and special
hack was implemented in Trusted Firmware to catch all SError events in EL3,
to ignore errors with code 0xbf000002 and not forwarding any other errors
to kernel and instead throw panic from EL3 Trusted Firmware handler.
Links to discussion and patches about this issue:
https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/commit/?id=3c7dcdac5c50
https://lore.kernel.org/linux-pci/20190316161243.29517-1-repk@triplefau.lt/
https://lore.kernel.org/linux-pci/971be151d24312cc533989a64bd454b4@www.loen.fr/
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/1541
But the real cause was the fact that during link retraining or after link
down event the PIO transfer may take longer time, up to the 1.44s until it
times out. This increased probability that a new PIO transfer would be
issued by kernel while previous one has not finished yet.
After applying this change into the kernel, it is possible to revert the
mentioned TF-A hack and SError events do not have to be caught in TF-A EL3.

[ Upstream commit fcb10ee27fb91b25b68d7745db9817ecea9f1038 ]
We should be very careful about the register values that will be used
for division or modulo operations, althrough the possibility that the
UARTBAUD register value is zero is very low, but we had better to deal
with the "bad data" of hardware in advance to avoid division or modulo

[ Upstream commit 7272b591c4cb9327c43443f67b8fbae7657dd9ae ]
In ibmasm_init_one, it calls ibmasm_init_remote_input_dev().
Inside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are
allocated by input_allocate_device(), and assigned to
sp->remote.mouse_dev and sp->remote.keybd_dev respectively.
In the err_free_devices error branch of ibmasm_init_one,
mouse_dev and keybd_dev are freed by input_free_device(), and return
error. Then the execution runs into error_send_message error branch
of ibmasm_init_one, where ibmasm_free_remote_input_dev(sp) is called
to unregister the freed sp->remote.mouse_dev and sp->remote.keybd_dev.
My patch add a "error_init_remote" label to handle the error of
ibmasm_init_remote_input_dev(), to avoid the uaf bugs.

This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f.
I've explained that optional FireWire card for d.2 is also built-in to
d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has
'Mackie DJ Mixer' in its model name of configuration ROM. On the other
hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC
and has 'd.Pro' in its model name according to manuals and user
experiences. The former card is not the card for d.2 Pro. They are similar
in appearance but different internally.

hardcoded, such that the function always returned the page0 contents. Fixed
so that the function can retrieve any page.

[ Upstream commit e30d55137edef47434c40d7570276a0846fe922c ]
An 'unexpected timeout' message may be seen in a point-2-point topology.
The message occurs when a PLOGI is received before the driver is notified
of FLOGI completion. The FLOGI completion failure causes discovery to be
triggered for a second time. The discovery timer is restarted but no new
discovery activity is initiated, thus the timeout message eventually
appears.
In point-2-point, when discovery has progressed before the FLOGI completion
is processed, it is not a failure. Add code to FLOGI completion to detect
that discovery has progressed and exit the FLOGI handling (noop'ing it).

[ Upstream commit ea2f0f77538c50739b9fb4de4700cee5535e1f77 ]
The sysfs handling function sdev_store_queue_depth() enforces that the sdev
queue depth cannot exceed shost can_queue. The initial sdev queue depth
comes from shost cmd_per_lun. However, the LLDD may manually set
cmd_per_lun to be larger than can_queue, which leads to an initial sdev
queue depth greater than can_queue.
Such an issue was reported in [0], which caused a hang. That has since been
fixed in commit fc09acb7de31 ("scsi: scsi_debug: Fix cmd_per_lun, set to
max_queue").
Stop this possibly happening for other drivers by capping shost cmd_per_lun
at shost can_queue.

In the probe function, if the final 'serial_config()' fails, 'info' is
leaking.
Add a resource handling path to free this memory.

There are a couple places where we could free the iscsi_cls_conn while it's
still in use. This adds some helpers to get/put a refcount on the struct
and converts an exiting user. Subsequent commits will then use the helpers
to fix 2 bugs in the eh code.

[ Upstream commit ec29d0ac29be366450a7faffbcf8cba3a6a3b506 ]
If we haven't done a unbind target call we can race where
iscsi_conn_teardown wakes up the EH thread and then frees the conn while
those threads are still accessing the conn ehwait.
We can only do one TMF per session so this just moves the TMF fields from
the conn to the session. We can then rely on the
iscsi_session_teardown->iscsi_remove_session->__iscsi_unbind_session call
to remove the target and it's devices, and know after that point there is
no device or scsi-ml callout trying to access the session.

[ Upstream commit bdd4aad7ff92ae39c2e93c415bb6761cb8b584da ]
The iscsi offload drivers are setting the shost->max_id to the max number
of sessions they support. The problem is that max_id is not the max number
of targets but the highest identifier the targets can have. To use it to
limit the number of targets we need to set it to max sessions - 1, or we
can end up with a session we might not have preallocated resources for.

[ Upstream commit 0d3e5a057992bdc66e4dca2ca50b77fa4a7bd90e ]
This test will require /dev/rtc0, the default RTC device, or one
specified by user to run. Since this default RTC is not guaranteed to
exist on all of the devices, so check its existence first, otherwise
skip this test with the kselftest skip code 4.
Without this patch this test will fail like this on a s390x zVM:
$ selftests: timers: rtcpie
$ /dev/rtc0: No such file or directory
not ok 1 selftests: timers: rtcpie # exit=22
With this patch:
$ selftests: timers: rtcpie
$ Default RTC /dev/rtc0 does not exist. Test Skipped!
not ok 9 selftests: timers: rtcpie # SKIP
Fixed up change log so "With this patch" text doesn't get dropped.

[ Upstream commit c305366a37441c2ac90b08711cb6f032b43672f2 ]
snd_sb_qsound_destroy() contains the calls of removing the previously
created mixer controls, but it doesn't clear the pointers. As
snd_sb_qsound_destroy() itself may be repeatedly called via ioctl,
this could lead to double-free potentially.
Fix it by clearing the struct fields properly afterwards.

Commit f959dcd6ddfd29235030e8026471ac1b022ad2b0 (dma-direct: Fix
potential NULL pointer dereference) added a null check on the
dma_mask pointer of the kernel's device structure.
Add a dma_mask variable to the ps3_dma_region structure and set
the device structure's dma_mask pointer to point to this new variable.
Fixes runtime errors like these:

[ Upstream commit 45677c9aebe926192e59475b35a1ff35ff2d4217 ]
The "no_handler_test" in ebb selftests attempts to read the PMU
registers twice via helper function "dump_ebb_state". First dump is
just before closing of event and the second invocation is done after
closing of the event. The original intention of second
dump_ebb_state was to dump the state of registers at the end of
the test when the counters are frozen. But this will be achieved
with the first call itself since sample period is set to low value
and PMU will be frozen by then. Hence patch removes the
dump which was done before closing of the event.

[ Upstream commit cac7100d4c51c04979dacdfe6c9a5e400d3f0a27 ]
Inside function hideep_nvm_unlock(), variable "unmask_code" could
be uninitialized if hideep_pgm_r_reg() returns error, however, it
is used in the later if statement after an "and" operation, which
is potentially unsafe.

[ Upstream commit 50ebe56222bfa0911a932930f9229ee5995508d9 ]
A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.
I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.
I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.

Running sparse checker it shows warning message about
incorrect endianness used for descriptor initialization:
| f_hid.c:91:43: warning: incorrect type in initializer (different base types)
| f_hid.c:91:43: expected restricted __le16 [usertype] bcdHID
| f_hid.c:91:43: got int
Fixing issue with cpu_to_le16() macro, however this is not a real issue
as the value is the same both endians.

[ Upstream commit b9481a667a90ec739995e85f91f3672ca44d6ffa ]
According to <linux/backlight.h> .update_status() is supposed to
return 0 on success and a negative error code otherwise. Adapt
lm3630a_bank_a_update_status() and lm3630a_bank_b_update_status() to
actually do it.
While touching that also add the error code to the failure message.

The function hda_tegra_first_init() neglects to check the return
value after executing platform_get_irq().
hda_tegra_first_init() should check the return value (if negative
error number) for errors so as to not pass a negative value to
the devm_request_irq().
Fix it by adding a check for the return value irq_id.

Some devices don't drain their pipelines if we don't make sure that
the corresponding output port is in reset before programming it for
a new trace capture, resulting in bits of old trace appearing in the
new trace capture. Fix that by explicitly making sure the reset is
asserted before programming new trace capture.

[ Upstream commit b64210f2f7c11c757432ba3701d88241b2b98fb1 ]
If an i2c client receives an interrupt during reboot or shutdown it may
be too late to service it by making an i2c transaction on the bus
because the i2c controller has already been shutdown. This can lead to
system hangs if the i2c controller tries to make a transfer that is
doomed to fail because the access to the i2c pins is already shut down,
or an iommu translation has been torn down so i2c controller register
access doesn't work.
Let's simply disable the irq if there isn't a shutdown callback for an
i2c client when there is an irq associated with the device. This will
make sure that irqs don't come in later than the time that we can handle
it. We don't do this if the i2c client device already has a shutdown
callback because presumably they're doing the right thing and quieting
the device so irqs don't come in after the shutdown callback returns.

[ Upstream commit 2c484419efc09e7234c667aa72698cb79ba8d8ed ]
lz4 compatible decompressor is simple. The format is underspecified and
relies on EOF notification to determine when to stop. Initramfs buffer
format[1] explicitly states that it can have arbitrary number of zero
padding. Thus when operating without a fill function, be extra careful to
ensure that sizes less than 4, or apperantly empty chunksizes are treated
as EOF.
To test this I have created two cpio initrds, first a normal one,
main.cpio. And second one with just a single /test-file with content
"second" second.cpio. Then i compressed both of them with gzip, and with
lz4 -l. Then I created a padding of 4 bytes (dd if=/dev/zero of=pad4 bs=1
count=4). To create four testcase initrds:
1) main.cpio.gzip + extra.cpio.gzip = pad0.gzip
2) main.cpio.lz4 + extra.cpio.lz4 = pad0.lz4
3) main.cpio.gzip + pad4 + extra.cpio.gzip = pad4.gzip
4) main.cpio.lz4 + pad4 + extra.cpio.lz4 = pad4.lz4
The pad4 test-cases replicate the initrd load by grub, as it pads and
aligns every initrd it loads.
All of the above boot, however /test-file was not accessible in the initrd
for the testcase #4, as decoding in lz4 decompressor failed. Also an
error message printed which usually is harmless.
Whith a patched kernel, all of the above testcases now pass, and
/test-file is accessible.
This fixes lz4 initrd decompress warning on every boot with grub. And
more importantly this fixes inability to load multiple lz4 compressed
initrds with grub. This patch has been shipping in Ubuntu kernels since
January 2021.

A consumer is expected to disable a PWM before calling pwm_put(). And if
they didn't there is hopefully a good reason (or the consumer needs
fixing). Also if disabling an enabled PWM was the right thing to do,
this should better be done in the framework instead of in each low level
driver.
So drop the hardware modification from the .remove() callback.

[ Upstream commit 7fbf6b731bca347700e460d94b130f9d734b33e9 ]
Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 17047/77693 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

This module's remove path calls del_timer(). However, that function

timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

This driver's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

[ Upstream commit cb011044e34c293e139570ce5c01aed66a34345c ]
This was already attempted to fix via 1fccb73011ea: If the BIOS did not
enable TCO SMIs, the timer definitely needs to trigger twice in order to
cause a reboot. If TCO SMIs are on, as well as SMIs in general, we can
continue to assume that the BIOS will perform a reboot on the first
timeout.
QEMU with its ICH9 and related BIOS falls into the former category,
currently taking twice the configured timeout in order to reboot the
machine. For iTCO version that fall under turn_SMI_watchdog_clear_off,
this is also true and was currently only addressed for v1, irrespective
of the turn_SMI_watchdog_clear_off value.

[ Upstream commit aee8c67a4faa40a8df4e79316dbfc92d123989c1 ]
When *RSTOR from user memory raises an exception, there is no way to
differentiate them. That's bad because it forces the slow path even when
the failure was not a fault. If the operation raised eg. #GP then going
through the slow path is pointless.
Use _ASM_EXTABLE_FAULT() which stores the trap number and let the exception
fixup return the negated trap number as error.
This allows to separate the fast path and let it handle faults directly and
avoid the slow path for all other exceptions.

The checks for page->mapping are odd, as set_page_dirty is an
address_space operation, and I don't see where it would be called on a
non-pagecache page.
The warning about the page lock also seems bogus. The comment over
set_page_dirty() says that it can be called without the page lock in
some rare cases. I don't think we want to warn if that's the case.

[ Upstream commit dfe52db13ab8d24857a9840ec7ca75eef800c26c ]
This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

[ Upstream commit 86f7fa71cd830d18d7ebcaf719dffd5ddfe1acdd ]
A consumer is expected to disable a PWM before calling pwm_put(). And if
they didn't there is hopefully a good reason (or the consumer needs
fixing). Also if disabling an enabled PWM was the right thing to do,
this should better be done in the framework instead of in each low level
driver.
So drop the hardware modification from the .remove() callback.

The Dell Vostro 3350 ACPI video-bus device reports spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there).
Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.

As marcosfrm reported in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=213089
Initramfs generators rely on "pre" softdeps (and "depends") to include
additional required modules.
F2FS does not declare "pre: crc32" softdep. Then every generator (dracut,
mkinitcpio...) has to maintain a hardcoded list for this purpose.
Hence let's use MODULE_SOFTDEP("pre: crc32") in f2fs code.
Fixes: 43b6573bac95 ("f2fs: use cryptoapi crc32 functions")

"utf16s_to_utf8s(..., buf, PAGE_SIZE)" puts up to PAGE_SIZE bytes into
"buf" and returns the number of bytes it actually put there. If it wrote
PAGE_SIZE bytes, the newline added by dsm_label_utf16s_to_utf8s() would
overrun "buf".
Reduce the size available for utf16s_to_utf8s() to use so there is always
space for the newline.

[ Upstream commit f3076cd8d1d5fa64b5e1fa5affc045c2fc123baa ]
The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt
line. Therefore, it is not actually part of the RT5033 MFD and needs
its own of_match_table to probe properly.
Also, given that it's independent of the MFD, there is actually
no need to make the Kconfig depend on MFD_RT5033. Although the driver
uses the shared <linux/mfd/rt5033.h> header, there is no compile
or runtime dependency on the RT5033 MFD driver.

Commit fc54bae28818 ("PCI: iproc: Allow allocation of multiple MSIs")
introduced multi-MSI support with a broken allocation mechanism (it failed
to reserve the proper number of bits from the inner domain). Natural
alignment of the base vector number was also not guaranteed.

[ Upstream commit 2dc0a201d0f59e6818ef443609f0850a32910844 ]
The interrupt affinity scheme used by this driver is incompatible with
multi-MSI as it implies moving the doorbell address to that of another MSI
group. This isn't possible for multi-MSI, as all the MSIs must have the
same doorbell address. As such it is restricted to systems with a single
CPU.

[ Upstream commit 5a2f966d0f3fa0ef6dada7ab9eda74cacee96b8a ]
It's unsafe to operate a vq from multiple threads.
Unfortunately this is exactly what we do when invoking
clean tx poll from rx napi.
Same happens with napi-tx even without the
opportunistic cleaning from the receive interrupt: that races
with processing the vq in start_xmit.
As a fix move everything that deals with the vq to under tx lock.

[ Upstream commit 681ba73c72302214686401e707e2087ed11a6556 ]
ld.lld warns that the '.modinfo' section is not currently handled:
ld.lld: warning: kernel/built-in.a(workqueue.o):(.modinfo) is being placed in '.modinfo'
ld.lld: warning: kernel/built-in.a(printk/printk.o):(.modinfo) is being placed in '.modinfo'

ld.lld: warning: kernel/built-in.a(rcu/update.o):(.modinfo) is being placed in '.modinfo'
The '.modinfo' section was added in commit 898490c010b5 ("moduleparam:
Save information about built-in modules in separate file") to the DISCARDS
macro but Hexagon has never used that macro. The unification of DISCARDS
happened in commit 023bf6f1b8bf ("linker script: unify usage of discard
definition") in 2009, prior to Hexagon being added in 2011.
Switch Hexagon over to the DISCARDS macro so that anything that is
expected to be discarded gets discarded.

[ Upstream commit 54b909436ede47e0ee07f1765da27ec2efa41e84 ]
The scnprintf() function silently truncates the printf() and returns
the number bytes that it was able to copy (not counting the NUL
terminator). Thus, the highest value it can return here is
"NAME_SIZE - 1" and the overflow check is dead code. Fix this by
using the snprintf() function which returns the number of bytes that
would have been copied if there was enough space and changing the
condition from "> NAME_SIZE" to ">= NAME_SIZE".

[ Upstream commit 6ab8c23096a29b69044209a5925758a6f88bd450 ]
"make dtbs_check" complains:
arch/arm/boot/dts/r8a7779-marzen.dt.yaml: display@fff80000: clock-names:0: 'du.0' was expected
Change the first clock name to match the DT bindings.
This has no effect on actual operation, as the Display Unit driver in
Linux does not use the first clock name on R-Car H1, but just grabs the
first clock.

Reserve GPIO pins 85-88 as these aren't meant to be accessible from the
application CPUs (causes reboot). Yet another fix similar to
9134586715e3, 5f8d3ab136d0, which is needed to allow angler to boot after

[ Upstream commit ddc873cd3c0af4faad6a00bffda21c3f775126dd ]
The i2c bus can freeze at the end of transaction so the bus can no longer work.
This scenario is improved by adding scl/sda gpios definitions to implement the
i2c bus recovery mechanism.

be undone by a corresponding pci_disable_pcie_error_reporting() call, as
already done in the remove function.

[ Upstream commit cddc40f5617e53f97ef019d5b29c1bd6cbb031ec ]
My series to clean up the unaligned access implementation
across architectures caused some mips randconfig builds to
fail with:
mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `decompress_kernel':
decompress.c:(.text.decompress_kernel+0x54): undefined reference to `__bswapsi2'
It turns out that this problem has already been fixed for the XZ
decompressor but now it also shows up in (at least) LZO and LZ4. From my
analysis I concluded that the compiler could always have emitted those
calls, but the different implementation allowed it to make otherwise
better decisions about not inlining the byteswap, which results in the
link error when the out-of-line code is missing.
While it could be addressed by adding it to the two decompressor
implementations that are known to be affected, but as this only adds
112 bytes to the kernel, the safer choice is to always add them.

[ Upstream commit 892ba7f18621a02af4428c58d97451f64685dba4 ]
Current 'perf report' fails to process a pipe input when --task or
--stat options are used. This is because they reset all the tool
callbacks and fails to find a matching event for a sample.
When pipe input is used, the event info is passed via ATTR records so it
needs to handle that operation. Otherwise the following error occurs.
Note, -14 (= -EFAULT) comes from evlist__parse_sample():
# perf record -a -o- sleep 1 | perf report -i- --stat
Can't parse sample, err = -14
0x271044 [0x38]: failed to process type: 9

[ Upstream commit 47ce8527fbba145a7723685bc9a27d9855e06491 ]
Accessing raw timers (currently only CLOCK_MONOTONIC_RAW) through VDSO
doesn't return the correct time when using the GIC as clock source.
The address of the GIC mapped page is in this case not calculated
correctly. The GIC mapped page is calculated from the VDSO data by
subtracting PAGE_SIZE:
void *get_gic(const struct vdso_data *data) {
return (void __iomem *)data - PAGE_SIZE;
}
However, the data pointer is not page aligned for raw clock sources.
This is because the VDSO data for raw clock sources (CS_RAW = 1) is
stored after the VDSO data for coarse clock sources (CS_HRES_COARSE = 0).
Therefore, only the VDSO data for CS_HRES_COARSE is page aligned:
+--------------------+
| |
| vd[CS_RAW] | ---+
| vd[CS_HRES_COARSE] | |
+--------------------+ | -PAGE_SIZE
| | |
| GIC mapped page | <--+
| |
+--------------------+
When __arch_get_hw_counter() is called with &vd[CS_RAW], get_gic returns
the wrong address (somewhere inside the GIC mapped page). The GIC counter
values are not returned which results in an invalid time.

commit 04bef83a3358946bfc98a5ecebd1b0003d83d882 upstream.
When a PIM hello packet is received on a bridge port with multicast
snooping enabled, we mark it as a router port automatically, that
includes adding that port the router port list. The multicast lock
protects that list, but it is not acquired in the PIM message case
leading to a race condition, we need to take it to fix the race.
