[ Upstream commit bdb19d01026a5cccfa437be8adcf2df472c5889e ]
The hibernation code is broken and has never been enabled in mainline
and should thus be dropped.
Remove the hibernation bits from the gadget code, which effectively
reverts commits e1dadd3b0f27 ("usb: dwc3: workaround: bogus hibernation
events") and 7b2a0368bbc9 ("usb: dwc3: gadget: set KEEP_CONNECT in case
of hibernation") except for the spurious interrupt warning.

Do not call gadget stop until the poll for controller halt is
completed. DEVTEN is cleared as part of gadget stop, so the intention to
allow ep0 events to continue while waiting for controller halt is not
happening.

[ Upstream commit 45121ad4a1750ca47ce3f32bd434bdb0cdbf0043 ]
The PSP IRQ is edge-triggered (MSI or MSI-X) in all cases supported by
the psp module so clear the interrupt status register early in the
handler to prevent missed interrupts. sev_irq_handler() calls wake_up()
on a wait queue, which can result in a new command being submitted from
a different CPU. This then races with the clearing of isr and can result
in missed interrupts. A missed interrupt results in a command waiting
until it times out, which results in the psp being declared dead.
This is unlikely on bare metal, but has been observed when running
virtualized. In the cases where this is observed, sev->cmdresp_reg has
PSP_CMDRESP_RESP set which indicates that the command was processed
correctly but no interrupt was asserted.
The full sequence of events looks like this:
CPU 1: submits SEV cmd #1
CPU 1: calls wait_event_timeout()
CPU 0: enters psp_irq_handler()
CPU 0: calls sev_handler()->wake_up()
CPU 1: wakes up; finishes processing cmd #1
CPU 1: submits SEV cmd #2
CPU 1: calls wait_event_timeout()
PSP: finishes processing cmd #2; interrupt status is still set; no interrupt
CPU 0: clears intsts
CPU 0: exits psp_irq_handler()
CPU 1: wait_event_timeout() times out; psp_dead=true

[ Upstream commit 84822215acd15bd86a7759a835271e63bba83a7b ]
The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

[ Upstream commit 4eddee70140b3ae183398b246a609756546c51f1 ]
Introduce a new (no SFDP) flag for the feature that we are about to
support: Read While Write. This means, if the chip has several banks and
supports RWW, once a page of data to write has been transferred into the
chip's internal SRAM, another read operation happening on a different
bank can be performed during the tPROG delay.

[ Upstream commit 9fd0945fe6fadfb6b54a9cd73be101c02b3e8134 ]
Infineon(Cypress) SEMPER NOR flash family has on-die ECC and its program
granularity is 16-byte ECC data unit size. JFFS2 supports write buffer
mode for ECC'd NOR flash. Provide a way to clear the MTD_BIT_WRITEABLE
flag in order to enable JFFS2 write buffer mode support.
A new SNOR_F_ECC flag is introduced to determine if the part has on-die
ECC and if it has, MTD_BIT_WRITEABLE is unset.
In vendor specific driver, a common cypress_nor_ecc_init() helper is
added. This helper takes care for ECC related initialization for SEMPER
flash family by setting up params->writesize and SNOR_F_ECC.

[ Upstream commit 721d3e91bfc93975c5e1a76c7d588dd8df5d82da ]
Not all Qcom platforms support IRQ mode for ECC handling. For those
platforms, the current EDAC driver will not be probed due to missing ECC
IRQ in devicetree.
So add support for polling mode so that the EDAC driver can be used on all
Qcom platforms supporting LLCC.
The polling delay of 5000ms is chosen based on Qcom downstream/vendor
driver.

[ Upstream commit cca94f1dd6d0a4c7e5c8190672f5747e3c00ddde ]
The platforms based on SDM845 SoC locks the access to EDAC registers in the
bootloader. So probing the EDAC driver will result in a crash. Hence,
disable the creation of EDAC platform device on all SDM845 devices.
The issue has been observed on Lenovo Yoga C630 and DB845c.
While at it, also sort the members of `struct qcom_llcc_config` to avoid
any holes in-between.

- saves 1 pointer in the 'zynqmp_ipi_pdata' structure
- saves an indirection when using this array
- saves some LoC and avoids some always spurious pointer arithmetic

If the MFT record of ntfs inode is not a base record, inode->i_op can be
NULL. And a null-ptr-deref may happen:
ntfs_lookup()
dir_search_u() # inode->i_op is set to NULL
d_splice_alias()
__d_add()
d_flags_for_inode() # inode->i_op->get_link null-ptr-deref
Fix this by adding a Check on inode->i_op before calling the
d_splice_alias() function.

Most of the time, calls to get_guest_pgd result in calling
kvm_read_cr3 (the exception is only nested TDP). Hardcode
the default instead of using the get_cr3 function, avoiding
a retpoline if they are enabled.

[ Upstream commit 01b31714bd90be2784f7145bf93b7f78f3d081e1 ]
There is no need to unload the MMU roots with TDP enabled when only
CR0.WP has changed -- the paging structures are still valid, only the
permission bitmap needs to be updated.
One heavy user of toggling CR0.WP is grsecurity's KERNEXEC feature to
implement kernel W^X.
The optimization brings a huge performance gain for this case as the
following micro-benchmark running 'ssdd 10 50000' from rt-tests[1] on a
grsecurity L1 VM shows (runtime in seconds, lower is better):
legacy TDP shadow
kvm-x86/next@d8708b 8.43s 9.45s 70.3s
+patch 5.39s 5.63s 70.2s
For legacy MMU this is ~36% faster, for TDP MMU even ~40% faster. Also
TDP and legacy MMU now both have a similar runtime which vanishes the
need to disable TDP MMU for grsecurity.
Shadow MMU sees no measurable difference and is still slow, as expected.

[ Upstream commit 74cdc836919bf34684ef66f995273f35e2189daf ]
Make use of the kvm_read_cr{0,4}_bits() helper functions when we only
want to know the state of certain bits instead of the whole register.
This not only makes the intent cleaner, it also avoids a potential
VMREAD in case the tested bits aren't guest owned.

[ Upstream commit fb509f76acc8d42bed11bca308404f81c2be856a ]
Guests like grsecurity that make heavy use of CR0.WP to implement kernel
level W^X will suffer from the implied VMEXITs.
With EPT there is no need to intercept a guest change of CR0.WP, so
simply make it a guest owned bit if we can do so.
This implies that a read of a guest's CR0.WP bit might need a VMREAD.
However, the only potentially affected user seems to be kvm_init_mmu()
which is a heavy operation to begin with. But also most callers already
cache the full value of CR0 anyway, so no additional VMREAD is needed.
The only exception is nested_vmx_load_cr3().
This change is VMX-specific, as SVM has no such fine grained control
register intercept control.

[ Upstream commit cf9f4c0eb1699d306e348b1fd0225af7b2c282d3 ]
Refresh the MMU's snapshot of the vCPU's CR0.WP prior to checking for
permission faults when emulating a guest memory access and CR0.WP may be
guest owned. If the guest toggles only CR0.WP and triggers emulation of
a supervisor write, e.g. when KVM is emulating UMIP, KVM may consume a
stale CR0.WP, i.e. use stale protection bits metadata.
Note, KVM passes through CR0.WP if and only if EPT is enabled as CR0.WP
is part of the MMU role for legacy shadow paging, and SVM (NPT) doesn't
support per-bit interception controls for CR0. Don't bother checking for
EPT vs. NPT as the "old == new" check will always be true under NPT, i.e.
the only cost is the read of vcpu->arch.cr4 (SVM unconditionally grabs CR0
from the VMCB on VM-Exit).

[ Upstream commit 72a03627443d5bc7032ab98bd784740cd8a76f8a ]
Currently all the object types in the rxe driver are allocated in
rdma-core except for MRs. By moving tha kzalloc() call outside of
the pool code the rxe_alloc() subroutine can be eliminated and code
checking for MR as a special case can be removed.
This patch moves the kzalloc() and kfree_rcu() calls into the mr
registration and destruction verbs. It removes that code from
rxe_pool.c including the rxe_alloc() subroutine which is no longer
used.

[ Upstream commit a9fb3287211e64b94ceb2b6b4791cc2b829d0d56 ]
Replace the name rxe_dbg with rxe_dbg_dev which better matches
the remaining rxe_dbg_xxx macros for debug messages with a
rxe device parameter. Reuse the name rxe_dbg for debug messages
which do not have a rxe device parameter.

[ Upstream commit 9ac01f434a1eb56ea94611bd75cf62fa276b41f4 ]
Extend the dbg log messages (e.g. rxe_dbg_xxx) to include

Commit 7e1d728a94ca ("ASoC: Intel: soc-acpi-byt: Add new WM5102 ACPI HID")
added an extra HID to wm5102_comp_ids.codecs, but it forgot to bump
wm5102_comp_ids.num_codecs, causing the last codec HID in the codecs list
to no longer work.
Bump wm5102_comp_ids.num_codecs to fix this.

[ Upstream commit c5749639f2d0a1f6cbe187d05f70c2e7c544d748 ]
In qedi_probe() we call __qedi_probe() which initializes
&qedi->recovery_work with qedi_recovery_handler() and
&qedi->board_disable_work with qedi_board_disable_work().
When qedi_schedule_recovery_handler() is called, schedule_delayed_work()
will finally start the work.
In qedi_remove(), which is called to remove the driver, the following
sequence may be observed:
Fix this by finishing the work before cleanup in qedi_remove().
CPU0 CPU1
|qedi_recovery_handler
qedi_remove |
__qedi_remove |
iscsi_host_free |
scsi_host_put |
//free shost |
|iscsi_host_for_each_session
|//use qedi->shost
Cancel recovery_work and board_disable_work in __qedi_remove().

[ Upstream commit 2b5fdc0f5caa505afe34d608e2eefadadf2ee67a ]
Inside the loop in rxrpc_wait_to_be_connected() it checks call->error to
see if it should exit the loop without first checking the call state. This
is probably safe as if call->error is set, the call is dead anyway, but we
should probably wait for the call state to have been set to completion
first, lest it cause surprise on the way out.
Fix this by only accessing call->error if the call is complete. We don't
actually need to access the error inside the loop as we'll do that after.
This caused the following report:

[ Upstream commit c23ae5091a8b3e50fe755257df020907e7c029bb ]
Commit 4fe815850bdc ("ixgbe: let the xdpdrv work with more than 64 cpus")
adds support to allow XDP programs to run on systems with more than
64 CPUs by locking the XDP TX rings and indexing them using cpu % 64
(IXGBE_MAX_XDP_QS).
Upon trying this out patch on a system with more than 64 cores,
the kernel paniced with an array-index-out-of-bounds at the return in
ixgbe_determine_xdp_ring in ixgbe.h, which means ixgbe_determine_xdp_q_idx
was just returning the cpu instead of cpu % IXGBE_MAX_XDP_QS. An example
splat:

I think this is how it happens:
Upon loading the first XDP program on a system with more than 64 CPUs,
ixgbe_xdp_locking_key is incremented in ixgbe_xdp_setup. However,
immediately after this, the rings are reconfigured by ixgbe_setup_tc.
ixgbe_setup_tc calls ixgbe_clear_interrupt_scheme which calls
ixgbe_free_q_vectors which calls ixgbe_free_q_vector in a loop.
ixgbe_free_q_vector decrements ixgbe_xdp_locking_key once per call if
it is non-zero. Commenting out the decrement in ixgbe_free_q_vector
stopped my system from panicing.
I suspect to make the original patch work, I would need to load an XDP
program and then replace it in order to get ixgbe_xdp_locking_key back
above 0 since ixgbe_setup_tc is only called when transitioning between
XDP and non-XDP ring configurations, while ixgbe_xdp_locking_key is
incremented every time ixgbe_xdp_setup is called.
Also, ixgbe_setup_tc can be called via ethtool --set-channels, so this
becomes another path to decrement ixgbe_xdp_locking_key to 0 on systems
with more than 64 CPUs.
Since ixgbe_xdp_locking_key only protects the XDP_TX path and is tied
to the number of CPUs present, there is no reason to disable it upon
unloading an XDP program. To avoid confusion, I have moved enabling
ixgbe_xdp_locking_key into ixgbe_sw_init, which is part of the probe path.

[ Upstream commit c222b292a3568754828ffd30338d2909b14ed160 ]
For each lmac port, MCS has two MCS_TOP_SLAVE_CHANNEL_CONFIGX
registers. For CN10KB both register need to be configured for the
port level mcs bypass to work. This patch also sets bitmap
of flowid/secy entry reserved for default bypass so that these
entries can be shown in debugfs.

write to individual registers will fail. Hence write to all
TCAM_DATA registers and then to all TCAM_MASK registers.

[ Upstream commit 65cdc2b637a5749c7dec0ce14fe2c48f1f91f671 ]
When ptp timestamp is enabled in RPM, RPM will append 8B
timestamp header for all RX traffic. MCS need to skip these
8 bytes header while parsing the packet header, so that
correct tcam key is created for lookup.
This patch fixes the mcs parser configuration to skip this
8B header for ptp packets.

[ Upstream commit b8aebeaaf9ffb1e99c642eb3751e28981f9be475 ]
On CN10KB, MCS IP vector number, BBE and PAB interrupt mask
got changed to support more block level interrupts.
To address this changes, this patch fixes the bbe and pab
interrupt handlers.
Fixes: 6c635f78c474 ("octeontx2-af: cn10k: mcs: Handle MCS block interrupts")

[ Upstream commit 57d00d4364f314485092667d2a48718985515deb ]
On CN10KB silicon a single hardware macsec block is
present and offloads macsec operations for all the
ethernet LMACs. TCAM match with macsec ethertype 0x88e5
alone at RX side is not sufficient to distinguish all the
macsec interfaces created on top of netdevs. Hence append
the DMAC of the macsec interface too. Otherwise the first
created macsec interface only receives all the macsec traffic.

When freeing MCS hardware resources like SecY, SC and
SA the corresponding stats needs to be cleared. Otherwise
previous stats are shown in newly created macsec interfaces.

[ Upstream commit 9bdfe61054fb2b989eb58df20bf99c0cf67e3038 ]
Macsec stats like InPktsLate and InPktsDelayed share
same counter in hardware. If SecY replay_protect is true
then counter represents InPktsLate otherwise InPktsDelayed.
This mode change was tracked based on protect_frames
instead of replay_protect mistakenly. Similarly InPktsUnchecked
and InPktsOk share same counter and mode change was tracked
based on validate_check instead of validate_disabled.
This patch fixes those problems.

[ Upstream commit 6f75cd166a5a3c0bc50441faa8b8304f60522fdd ]
ncsi_channel_is_tx() determines whether a given channel should be
used for Tx or not. However, when reconfiguring the channel by
handling a Configuration Required AEN, there is a misjudgment that
the channel Tx has already been enabled, which results in the Enable
Channel Network Tx command not being sent.
Clear the channel Tx enable flag before reconfiguring the channel to
avoid the misjudgment.

[ Upstream commit 7e692df3933628d974acb9f5b334d2b3e885e2a6 ]
David Ahern reported crashes in skb_copy_ubufs() caused by TCP tx zerocopy
using hugepages, and skb length bigger than ~68 KB.
skb_copy_ubufs() assumed it could copy all payload using up to
MAX_SKB_FRAGS order-0 pages.
This assumption broke when BIG TCP was able to put up to 512 KB per skb.
We did not hit this bug at Google because we use CONFIG_MAX_SKB_FRAGS=45
and limit gso_max_size to 180000.
A solution is to use higher order pages if needed.
v2: add missing __GFP_COMP, or we leak memory.
Fixes: 7c4e983c4f3c ("net: allow gso_max_size to exceed 65536")

[ Upstream commit da94a7781fc3c92e7df7832bc2746f4d39bc624e ]
Error handler of tcf_block_bind() frees the whole bo->cb_list on error.
However, by that time the flow_block_cb instances are already in the driver
list because driver ndo_setup_tc() callback is called before that up the
call chain in tcf_block_offload_cmd(). This leaves dangling pointers to
freed objects in the list and causes use-after-free[0]. Fix it by also
removing flow_block_cb instances from driver_list before deallocating them.

[ Upstream commit c88f8d5cd95fd039cff95d682b8e71100c001df0 ]
When a tunnel device is bound with the underlying device, its
dev->needed_headroom needs to be updated properly. IPv4 tunnels
already do the same in ip_tunnel_bind_dev(). Otherwise we may
not have enough header room for skb, especially after commit
b17f709a2401 ("gue: TX support for using remote checksum offload option").

[ Upstream commit 46ef24c60f8ee70662968ac55325297ed4624d61 ]
On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT46 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

[ Upstream commit dc6456e938e938d64ffb6383a286b2ac9790a37f ]
The skb hash comes from sk->sk_txhash when using TCP, except for some
IPv6 RST packets. This is because in tcp_v6_send_reset when not in
TIME_WAIT the hash is taken from sk->sk_hash, while it should come from
sk->sk_txhash as those two hashes are not computed the same way.
Packetdrill script to test the above,
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
+0 connect(3, ..., ...) = -1 EINPROGRESS (Operation now in progress)

Kernel hang in blkg_destroy_all() when total blkg greater than
BLKG_DESTROY_BATCH_SIZE, because of not removing destroyed blkg in
blkg_list. So the size of blkg_list is same after destroying a
batch of blkg, and the infinite 'restart' occurs.
Since blkg should stay on the queue list until blkg_free_workfn(),
skip destroyed blkg when restart a new round, which will solve this
kernel hang issue and satisfy the previous will to restart.

[ Upstream commit a15c90b67a662c75f469822a7f95c7aaa049e28f ]
Currently kernel_page_present() function doesn't support huge page
detection causes the function to mistakenly return false to the
hibernation core.
Add huge page detection to the function to solve the problem.

[ Upstream commit 9f855779a3874eee70e9f6be57b5f7774f14e510 ]
Update the msg->len value correctly for SMBUS block read. The discrepancy
went unnoticed as msg->len is used in SMBUS transfers only when a PEC
byte is added.

[ Upstream commit 526f28bd0fbdc699cda31426928802650c1528e5 ]
There are cases where the device is adminstratively UP, but operationally
down. For example, we have a physical device (Nvidia ConnectX-6 Dx, 25Gbps)
who's cable was pulled out, here is its ip link output:
5: ens2f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether b8:ce:f6:4b:68:35 brd ff:ff:ff:ff:ff:ff
altname enp179s0f1np1
As you can see, it's administratively UP but operationally down.
In this case, sending a packet to this port caused a nasty kernel hang (so
nasty that we were unable to capture it). Aborting a transmit based on
operational status (in addition to administrative status) fixes the issue.

[ Upstream commit 8ceda6d5a1e5402fd852e6cc59a286ce3dc545ee ]
The feature of flow control becomes abnormal, if the device sends a
pause frame and the tx/rx is disabled before sending a release frame. It
causes the lost of packets.
Set PLA_RX_FIFO_FULL and PLA_RX_FIFO_EMPTY to zeros before disabling the
tx/rx. And, toggle FC_PATCH_TASK before enabling tx/rx to reset the flow
control patch and timer. Then, the hardware could clear the state and
the flow control becomes normal after enabling tx/rx.
Besides, remove inline for fc_pause_on_auto() and fc_pause_off_auto().

[ Upstream commit cce8334f4aacd9936309a002d4a4de92a07cd2c2 ]
Move setting r8153b_rx_agg_chg_indicate() for 2.5G devices. The
r8153b_rx_agg_chg_indicate() has to be called after enabling tx/rx.
Otherwise, the coalescing settings are useless.

The sfc driver does not report QSFP module EEPROM contents correctly
as only the first page is fetched from hardware.
Commit 0e1a2a3e6e7d ("ethtool: Add SFF-8436 and SFF-8636 max EEPROM
length definitions") added ETH_MODULE_SFF_8436_MAX_LEN for the overall
size of the EEPROM info, so use that to report the full EEPROM contents.

[ Upstream commit 0eb362d254814ce04848730bf32e75b8ee1a4d6c ]
When sendmsg() creates an rxrpc call, it queues it to wait for a connection
and channel to be assigned and then waits before it can start shovelling
data as the encrypted DATA packet content includes a summary of the
connection parameters.
However, sendmsg() may get interrupted before a connection gets assigned
and further sendmsg() calls will fail with EBUSY until an assignment is
made.
Fix this so that the call can at least be aborted without failing on
EBUSY. We have to be careful here as sendmsg() mustn't be allowed to start
the call timer if the call doesn't yet have a connection assigned as an
oops may follow shortly thereafter.

[ Upstream commit db099c625b13a74d462521a46d98a8ce5b53af5d ]
afs_make_call() calls rxrpc_kernel_begin_call() to begin a call (which may
get stalled in the background waiting for a connection to become
available); it then calls rxrpc_kernel_set_max_life() to set the timeouts -
but that starts the call timer so the call timer might then expire before
we get a connection assigned - leading to the following oops if the call
stalled:

Fix this by noting the timeouts in struct rxrpc_call when the call is
created. The timer will be started when the first packet is transmitted.
It shouldn't be possible to trigger this directly from userspace through
AF_RXRPC as sendmsg() will return EBUSY if the call is in the
waiting-for-conn state if it dropped out of the wait due to a signal.

From: Felix Fietkau <nbd@nbd.name>
[ Upstream commit c6d96df9fa2c1d19525239d4262889cce594ce6c ]
Through testing I found out that hardware vlan rx offload support seems to
have some hardware issues. At least when using multiple MACs and when
receiving tagged packets on the secondary MAC, the hardware can sometimes
start to emit wrong tags on the first MAC as well.
In order to avoid such issues, drop the feature configuration and use
the offload feature only for DSA hardware untagging on MT7621/MT7622
devices where this feature works properly.

CPU transcoder mask is used to iterate over the available
CPU transcoders in the macro for_each_cpu_transcoder().
The macro is broken on MTL and got highlighted when audio
state was being tracked for each transcoder added in [1].
Add the missing CPU transcoder mask which is similar to ADL-P
mask but without DSI transcoders.

[ Upstream commit 048486f81d01db4d100af021ee2ea211d19732a0 ]
APR table contains the lmtst base address of PF/VFs. These entries
are updated by the PF/VF during the device probe. The lmtst address
is fetched from HW using "TXN_REQ" and "ADDR_RSP_STS" registers.
The lock tries to protect these registers from getting overwritten
when multiple PFs invokes rvu_get_lmtaddr() simultaneously.
For example, if PF1 submit the request and got permitted before it
reads the response and PF2 got scheduled submit the request then the
response of PF1 is overwritten by the PF2 response.

[ Upstream commit c60a6b90e7890453f09e0d2163d6acadabe3415b ]
In the current driver, NPC exact match feature was not getting
enabled as configured bit was not read properly.
for_each_set_bit_from() need end bit as one bit post
position in the bit map to read NPC exact nibble enable
bits properly. This patch fixes the same.

[ Upstream commit cb5edce271764524b88b1a6866b3e626686d9a33 ]
Upon physical link change, firmware reports to the kernel about the
change along with the details like speed, lmac_type_id, etc.
Kernel derives lmac_type based on lmac_type_id received from firmware.
In a few scenarios, firmware returns an invalid lmac_type_id, which
is resulting in below kernel panic. This patch adds the missing
validation of the lmac_type_id field.

Which results to filter only fragmets with (fragment_offset == 0).
As part of the fix, updated the mask to 0x20 to filter all the
fragmented packets irrespective of the fragment_offset value.

1. As per previous implementation, mask and control parameter to
generate the field hash value was not passed to the caller program.
Updated the secret key mbox to share that information as well,
as a part of the fix.
2. Earlier implementation did not consider hash reduction of both
source and destination IPv6 addresses. Only source IPv6 address
was considered. This fix solves that and provides option to hash

[ Upstream commit 5eb1b7220948a69298a436148a735f32ec325289 ]
Firmware enables PFs and allocate mbox resources for each of the PFs.
Currently PF driver configures mbox resources without checking whether
PF is enabled or not. This results in crash. This patch fixes this issue
by skipping disabled PF's mbox initialization.

From: Ido Schimmel <idosch@nvidia.com>
[ Upstream commit 9ad685dbfe7e856bbf17a7177b64676d324d6ed7 ]
It is not possible to set the number of lanes when setting link modes
using the legacy IOCTL ethtool interface. Since 'struct
ethtool_link_ksettings' is not initialized in this path, drivers receive
an uninitialized number of lanes in 'struct
ethtool_link_ksettings::lanes'.
When this information is later queried from drivers, it results in the
ethtool code making decisions based on uninitialized memory, leading to
the following KMSAN splat [1]. In practice, this most likely only
happens with the tun driver that simply returns whatever it got in the
set operation.
As far as I can tell, this uninitialized memory is not leaked to user
space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in
linkmodes_prepare_data().
Fix by initializing the structure in the IOCTL path. Did not find any
more call sites that pass an uninitialized structure when calling
'ethtool_ops::set_link_ksettings()'.

[ Upstream commit 4a54903ff68ddb33b6463c94b4eb37fc584ef760 ]
Add a check for NULL on the alloc return. If devlink_alloc() fails and
we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel.

[ Upstream commit 6a341729fb31b4c5df9f74f24b4b1c98410c9b87 ]
syzkaller reported a warning below [0].
We can reproduce it by sending 0-byte data from the (AF_PACKET,
SOCK_PACKET) socket via some devices whose dev->hard_header_len
is 0.
struct sockaddr_pkt addr = {
.spkt_family = AF_PACKET,
.spkt_device = "tun0",
};
int fd;
fd = socket(AF_PACKET, SOCK_PACKET, 0);
sendto(fd, NULL, 0, 0, (struct sockaddr *)&addr, sizeof(addr));
We have a similar fix for the (AF_PACKET, SOCK_RAW) socket as
commit dc633700f00f ("net/af_packet: check len when min_header_len
equals to 0").
Let's add the same test for the SOCK_PACKET socket.

[ Upstream commit 292a7d6fca33df70ca4b8e9b0d0e74adf87582dc ]
On machines without the Destroy Secure Configuration Fast UVC, the
topmost level of page tables is set aside and freed asynchronously
as last step of the asynchronous teardown.
Each gmap has a host_to_guest radix tree mapping host (userspace)
addresses (with 1M granularity) to gmap segment table entries (pmds).
If a guest is smaller than 2GB, the topmost level of page tables is the
segment table (i.e. there are only 2 levels). Replacing it means that
the pointers in the host_to_guest mapping would become stale and cause
all kinds of nasty issues.
This patch fixes the issue by disallowing asynchronous teardown for
guests with only 2 levels of page tables. Userspace should (and already
does) try using the normal destroy if the asynchronous one fails.
Update s390_replace_asce so it refuses to replace segment type ASCEs.
This is still needed in case the normal destroy VM fails.

[ Upstream commit c148dc8e2fa403be501612ee409db866eeed35c0 ]
Fix a potential race in gmap_make_secure() and remove the last user of
follow_page() without FOLL_GET.
The old code is locking something it doesn't have a reference to, and
as explained by Jason and David in this discussion:
https://lore.kernel.org/linux-mm/Y9J4P%2FRNvY1Ztn0Q@nvidia.com/
it can lead to all kind of bad things, including the page getting
unmapped (MADV_DONTNEED), freed, reallocated as a larger folio and the
unlock_page() would target the wrong bit.
There is also another race with the FOLL_WRITE, which could race
between the follow_page() and the get_locked_pte().
The main point is to remove the last use of follow_page() without
FOLL_GET or FOLL_PIN, removing the races can be considered a nice
bonus.

[ Upstream commit 37c218d8021e36e226add4bab93d071d30fe0704 ]
The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.
This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.
My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.
Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.
Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.
Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.

[ Upstream commit 120a56b01beed51ab5956a734adcfd2760307107 ]
On mt753x_cpu_port_enable() there's code that enables flooding for the CPU
port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports
are enabled, port 6 becomes the only port to forward the frames to. But
port 5 is the active port, so no frames received from the user ports will
be forwarded to port 5 which breaks network connectivity.
Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix
this issue by setting the bit that corresponds to the CPU port without
overwriting the other bits.
Clear the bits beforehand only for the MT7531 switch. According to the
documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference
Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and
UNU_FFP bits are set to 1 for MT7531, 0 for MT7530.
The commit 5e5502e012b8 ("net: dsa: mt7530: fix roaming from DSA user
ports") silently changed the method to set the bits on the MT7530_MFC.
Instead of clearing the relevant bits before mt7530_cpu_port_enable()
which runs under a for loop, the commit started doing it on
mt7530_cpu_port_enable().
Back then, this didn't really matter as only a single CPU port could be
used since the CPU port number was hardcoded. The driver was later changed
with commit 1f9a6abecf53 ("net: dsa: mt7530: get cpu-port via dp->cpu_dp
instead of constant") to retrieve the CPU port via dp->cpu_dp. With that,
this silent change became an issue for when using multiple CPU ports.

[ Upstream commit 299efdc2380aac588557f4d0b2ce7bee05bd0cf2 ]
We should check whether the current SFI (Stream Filter Instance) table
is full before creating a new SFI entry. However, the previous logic
checks the handle by mistake and might lead to unpredictable behavior.

[ Upstream commit 26312c685ae0bca61e06ac75ee158b1e69546415 ]
In the current xdp_xmit implementation, if any single frame fails to
transmit due to insufficient buffer descriptors, the function nevertheless
reports success in sending all frames. This results in erroneously
indicating that frames were transmitted when in fact they were dropped.
This patch fixes the issue by ensureing the return value properly
indicates the actual number of frames successfully transmitted, rather than
potentially reporting success for all frames when some could not transmit.

[ Upstream commit 07d85ba9d04e1ebd282f656a29ddf08c5b7b32a2 ]
Hundreds of "read LOST count failed" error messages may be displayed,
when the below command is launched.
perf record -e '{cpu/mem-loads-aux/,cpu/event=0xcd,umask=0x1/}:S' -a
According to the commit 89e3106fa25fb1b6 ("libperf: Handle read format
in perf_evsel__read()"), the PERF_FORMAT_GROUP is only available for
the leader. However, the record__read_lost_samples() goes through every
entry of an evlist, which includes both leader and member. The member
event errors out and triggers the error message. Since there may be
hundreds of CPUs on a server, the message will be printed hundreds of
times, which is very annoying.
The message itself is correct, but the pr_err is a overkill. Other error
messages in the record__read_lost_samples() are all pr_debug. To make
the output format consistent, change the pr_err("read LOST count
failed\n"); to pr_debug("read LOST count failed\n");.
User can still get the message via -v option.

results in incorrect IPC values. Fix by switching to new division
behavior.

[ Upstream commit 80c3a7d9f20401169283b5670dbb8d7ac07a1d55 ]
Python scripting can be used without libtraceevent. In particular,
scripting for Intel PT does not use tracepoints, and so does not need
libtraceevent support.
Alter the build and employ conditional compilation to allow Python
scripting without libtraceevent.
Example:
Before:
$ ldd `which perf` | grep -i python
$ ldd `which perf` | grep -i libtraceevent
$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.031 MB perf.data ]
$ perf script intel-pt-events.py |& head -3
Error: Couldn't find script `intel-pt-events.py'
See perf script -l for available scripts.
After:
$ ldd `which perf` | grep -i python
libpython3.10.so.1.0 => /lib/x86_64-linux-gnu/libpython3.10.so.1.0 (0x00007f4bac400000)
$ ldd `which perf` | grep -i libtraceevent
$ perf script intel-pt-events.py | head

[ Upstream commit 6094c7744bb0563e833e81d8df8513f9a4e7a257 ]
The earlier commit f0cdde28fecc0d7f ("perf hist: Improve srcfile sort
key performance") updated the srcfile logic but missed to change the
->cmp() callback which is called for every sample.
It should use the same logic like in the srcline to speed up the
processing because it'd return the same information repeatedly for the
same address. The real processing will be done in
sort__srcfile_collapse().

Commit 7f76b31130680fb3 ("perf list: Add IBM z16 event description for

However some entries of the public description contain UTF-8 characters
which breaks the build on some distros.
Fix this and remove the UTF-8 characters.

[ Upstream commit ecd4960d908e27e40b63a7046df2f942c148c6f6 ]
If no target is specified for 'latency' subcommand, the execution fails
because - 1 (invalid value) is written to set_ftrace_pid tracefs file.
Make system wide the default target, which is the same as the default
behavior of 'trace' subcommand.
Before the fix:
# perf ftrace latency -T schedule
failed to set ftrace pid
After the fix:
# perf ftrace latency -T schedule

Commit 3c22ba5243040c13 ("perf vendor events powerpc: Update POWER9
events") added and updated power9 PMU JSON events. However some of the
JSON events which are part of other.json and pipeline.json files,
contains UTF-8 characters in their brief description. Having UTF-8
character could breaks the perf build on some distros.
Fix this issue by removing the UTF-8 characters from other.json and

[ Upstream commit c160118a90d4acf335993d8d59b02ae2147a524e ]
Addresses of two data structure members were determined before
corresponding null pointer checks in the implementation of the function
“sort__sym_from_cmp”.
Thus avoid the risk for undefined behaviour by removing extra
initialisations for the local variables “from_l” and “from_r” (also
because they were already reassigned with the same value behind this
pointer check).
This issue was detected by using the Coccinelle software.

[ Upstream commit 449067f3fc9f340da54e383738286881e6634d0b ]
In this context, timeless refers to the trace data rather than the perf
event data. But when detecting whether there are timestamps in the trace
data or not, the presence of a timestamp flag on any perf event is used.
Since commit f42c0ce573df ("perf record: Always get text_poke events
with --kcore option") timestamps were added to a tracking event when
--kcore is used which breaks this detection mechanism. Fix it by
detecting if trace timestamps exist by looking at the ETM config flags.
This would have always been a more accurate way of doing it anyway.
This fixes the following error message when using --kcore with
Coresight:
$ perf record --kcore -e cs_etm// --per-thread
$ perf report
The perf.data/data data has no samples!

From: Herbert Xu <herbert@gondor.apana.org.au>
[ Upstream commit c35e03eaece71101ff6cbf776b86403860ac8cc3 ]
The crypto completion function currently takes a pointer to a
struct crypto_async_request object. However, in reality the API
does not allow the use of any part of the object apart from the
data field. For example, ahash/shash will create a fake object
on the stack to pass along a different data field.
This leads to potential bugs where the user may try to dereference
or otherwise use the crypto_async_request object.
This patch adds some temporary scaffolding so that the completion
function can take a void * instead. Once affected users have been
converted this can be removed.
The helper crypto_request_complete will remain even after the
conversion is complete. It should be used instead of calling
the completion function directly.

[ Upstream commit 4140aafcff167b5b9e8dae6a1709a6de7cac6f74 ]
CRYPTO_TFM_REQ_MAY_BACKLOG tells the crypto driver that it should
internally backlog requests until the crypto hw's queue becomes
full. At that point, crypto_engine backlogs the request and returns
-EBUSY. Calling driver such as dm-crypt then waits until the
complete() function is called with a status of -EINPROGRESS before
sending a new request.
The problem lies in the call to complete() with a value of -EINPROGRESS
that is made when a backlog item is present on the queue. The call is
done before the successful execution of the crypto request. In the case
that do_one_request() returns < 0 and the retry support is available,
the request is put back in the queue. This leads upper drivers to send
a new request even if the queue is still full.
The problem can be reproduced by doing a large dd into a crypto
dm-crypt device. This is pretty easy to see when using
Freescale CAAM crypto driver and SWIOTLB dma. Since the actual amount
of requests that can be hold in the queue is unlimited we get IOs error
and dma allocation.
The fix is to call complete with a value of -EINPROGRESS only if
the request is not enqueued back in crypto_queue. This is done
by calling complete() later in the code. In order to delay the decision,
crypto_queue is modified to correctly set the backlog pointer
when a request is enqueued back.

[ Upstream commit ecc68ee216c6c5b2f84915e1441adf436f1b019b ]
It seems that perf stat -b <prog id> doesn't produce any results:
$ perf stat -e cycles -b 4 -I 10000 -vvv
Control descriptor is not initialized
cycles: 0 0 0
time counts unit events
10.007641640 <not supported> cycles
Looks like this happens because fentry/fexit progs are getting loaded, but the
corresponding perf event is not enabled and not added into the events bpf map.
I think there is some mixing up between two type of bpf support, one for bperf
and one for bpf_profiler. Both are identified via evsel__is_bpf, based on which
perf events are enabled, but for the latter (bpf_profiler) a perf event is
required. Using evsel__is_bperf to check only bperf produces expected results:
$ perf stat -e cycles -b 4 -I 10000 -vvv
Control descriptor is not initialized
------------------------------------------------------------
perf_event_attr:

The final numbers correspond (at least in the level of magnitude) to the
same metric obtained via bpftool.

[ Upstream commit 3af15ff47c4df3af7b36ea8315f43c6b0af49253 ]
Change tdp_mmu to a read-only parameter and drop the per-vm
tdp_mmu_enabled. For 32-bit KVM, make tdp_mmu_enabled a macro that is
always false so that the compiler can continue omitting cals to the TDP
MMU.
The TDP MMU was introduced in 5.10 and has been enabled by default since
5.15. At this point there are no known functionality gaps between the
TDP MMU and the shadow MMU, and the TDP MMU uses less memory and scales
better with the number of vCPUs. In other words, there is no good reason
to disable the TDP MMU on a live system.
Purposely do not drop tdp_mmu=N support (i.e. do not force 64-bit KVM to
always use the TDP MMU) since tdp_mmu=N is still used to get test
coverage of KVM's shadow MMU TDP support, which is used in 32-bit KVM.

[ Upstream commit 991c8047b740f192a057d5f22df2f91f087cdb72 ]
Move kvm_mmu_{init,uninit}_tdp_mmu() behind tdp_mmu_enabled. This makes
these functions consistent with the rest of the calls into the TDP MMU
from mmu.c, and which is now possible since tdp_mmu_enabled is only
modified when the x86 vendor module is loaded. i.e. It will never change
during the lifetime of a VM.
This change also enabled removing the stub definitions for 32-bit KVM,
as the compiler will just optimize the calls out like it does for all
the other TDP MMU functions.
No functional change intended.

[ Upstream commit edbdb43fc96b11b3bfa531be306a1993d9fe89ec ]
Preserve TDP MMU roots until they are explicitly invalidated by gifting
the TDP MMU itself a reference to a root when it is allocated. Keeping a
reference in the TDP MMU fixes a flaw where the TDP MMU exhibits terrible
performance, and can potentially even soft-hang a vCPU, if a vCPU
frequently unloads its roots, e.g. when KVM is emulating SMI+RSM.
When KVM emulates something that invalidates _all_ TLB entries, e.g. SMI
and RSM, KVM unloads all of the vCPUs roots (KVM keeps a small per-vCPU
cache of previous roots). Unloading roots is a simple way to ensure KVM
flushes and synchronizes all roots for the vCPU, as KVM flushes and syncs
when allocating a "new" root (from the vCPU's perspective).
In the shadow MMU, KVM keeps track of all shadow pages, roots included, in
a per-VM hash table. Unloading a shadow MMU root just wipes it from the
per-vCPU cache; the root is still tracked in the per-VM hash table. When
KVM loads a "new" root for the vCPU, KVM will find the old, unloaded root
in the per-VM hash table.
Unlike the shadow MMU, the TDP MMU doesn't track "inactive" roots in a
per-VM structure, where "active" in this case means a root is either
in-use or cached as a previous root by at least one vCPU. When a TDP MMU
root becomes inactive, i.e. the last vCPU reference to the root is put,
KVM immediately frees the root (asterisk on "immediately" as the actual
freeing may be done by a worker, but for all intents and purposes the root
is gone).
The TDP MMU behavior is especially problematic for 1-vCPU setups, as
unloading all roots effectively frees all roots. The issue is mitigated
to some degree in multi-vCPU setups as a different vCPU usually holds a
reference to an unloaded root and thus keeps the root alive, allowing the
vCPU to reuse its old root after unloading (with a flush+sync).
The TDP MMU flaw has been known for some time, as until very recently,
KVM's handling of CR0.WP also triggered unloading of all roots. The
CR0.WP toggling scenario was eventually addressed by not unloading roots
when _only_ CR0.WP is toggled, but such an approach doesn't Just Work
for emulating SMM as KVM must emulate a full TLB flush on entry and exit
to/from SMM. Given that the shadow MMU plays nice with unloading roots
at will, teaching the TDP MMU to do the same is far less complex than
modifying KVM to track which roots need to be flushed before reuse.
Note, preserving all possible TDP MMU roots is not a concern with respect
to memory consumption. Now that the role for direct MMUs doesn't include
information about the guest, e.g. CR0.PG, CR0.WP, CR4.SMEP, etc., there
are _at most_ six possible roots (where "guest_mode" here means L2):
1. 4-level !SMM !guest_mode
2. 4-level SMM !guest_mode
3. 5-level !SMM !guest_mode
4. 5-level SMM !guest_mode
5. 4-level !SMM guest_mode
6. 5-level !SMM guest_mode
And because each vCPU can track 4 valid roots, a VM can already have all
6 root combinations live at any given time. Not to mention that, in
practice, no sane VMM will advertise different guest.MAXPHYADDR values
across vCPUs, i.e. KVM won't ever use both 4-level and 5-level roots for
a single VM. Furthermore, the vast majority of modern hypervisors will
utilize EPT/NPT when available, thus the guest_mode=%true cases are also
unlikely to be utilized.

[ Upstream commit 1d9c4172110e645b383ff13eee759728d74f1a5d ]
For some ops on channel:
1. lookup_chann_list(), possibly on high frequency.
2. ksmbd_chann_del().
Connection is used as indexing key to lookup channel, in that case,
linear search based on list may suffer a bit for performance.
Implements sess->ksmbd_chann_list as xarray.

[ Upstream commit f5c779b7ddbda30866cf2a27c63e34158f858c73 ]
This racy issue is triggered by sending concurrent session setup and
logoff requests. This patch does not set connection status as
KSMBD_SESS_GOOD if state is KSMBD_SESS_NEED_RECONNECT in session setup.
And relookup session to validate if session is deleted in logoff.

[ Upstream commit b096d97f47326b1e2dbdef1c91fab69ffda54d17 ]
ksmbd make a delay of 5 seconds on session setup to avoid dictionary
attacks. But the 5 seconds delay can be bypassed by using asynchronous
requests. This patch block all requests on current connection when
making a delay on sesstion setup failure.

client can indefinitely send smb2 session setup requests with
the SessionId set to 0, thus indefinitely spawning new sessions,
and causing indefinite memory usage. This patch limit to the number
of sessions using expired timeout and session state.

[ Upstream commit abcc506a9a71976a8b4c9bf3ee6efd13229c1e19 ]
When smb client send concurrent smb2 close and logoff request
with multichannel connection, It can cause racy issue. logoff request
free tcon and can cause UAF issues in smb2 close. When receiving logoff
request with multichannel, ksmbd should wait until all remaning requests
complete as well as ones in the current connection, and then make
session expired.

If we do get multiple notifications from firmware, then
we might have allocated 'notif', but don't free it. Fix
that by checking for duplicates before allocation.

We had a couple of checks for session in cifs_tree_connect
and cifs_mark_open_files_invalid, which were unnecessary.
And that was done with ses_lock. Changed that to tc_lock too.

[ Upstream commit 6be2ea33a4093402252724a00c4af8033725184c ]
Now that a DFS tcon manages its own list of DFS referrals and
sessions, there is no point in having a single worker to refresh
referrals of all DFS tcons. Make it faster and less prone to race
conditions when having several mounts by queueing a worker per DFS
tcon that will take care of refreshing only the DFS referrals related
to it.

commit 6f932d4ef007d6a4ae03badcb749fbb8f49196f6 upstream.
A call to btrfs_prev_leaf() may end up returning a path that points to the
same item (key) again. This happens if while btrfs_prev_leaf(), after we
release the path, a concurrent insertion happens, which moves items off
from a sibling into the front of the previous leaf, and an item with the
computed previous key does not exists.
For example, suppose we have the two following leaves:
Leaf A
-------------------------------------------------------------
| ... key (300 96 10) key (300 96 15) key (300 96 16) |
-------------------------------------------------------------
slot 20 slot 21 slot 22
Leaf B
-------------------------------------------------------------
| key (300 96 20) key (300 96 21) key (300 96 22) ... |
-------------------------------------------------------------
slot 0 slot 1 slot 2
If we call btrfs_prev_leaf(), from btrfs_previous_item() for example, with
a path pointing to leaf B and slot 0 and the following happens:
1) At btrfs_prev_leaf() we compute the previous key to search as:
(300 96 19), which is a key that does not exists in the tree;
2) Then we call btrfs_release_path() at btrfs_prev_leaf();
3) Some other task inserts a key at leaf A, that sorts before the key at
slot 20, for example it has an objectid of 299. In order to make room
for the new key, the key at slot 22 is moved to the front of leaf B.
This happens at push_leaf_right(), called from split_leaf().
After this leaf B now looks like:
--------------------------------------------------------------------------------
| key (300 96 16) key (300 96 20) key (300 96 21) key (300 96 22) ... |
--------------------------------------------------------------------------------
slot 0 slot 1 slot 2 slot 3
4) At btrfs_prev_leaf() we call btrfs_search_slot() for the computed
previous key: (300 96 19). Since the key does not exists,
btrfs_search_slot() returns 1 and with a path pointing to leaf B
and slot 1, the item with key (300 96 20);
5) This makes btrfs_prev_leaf() return a path that points to slot 1 of
leaf B, the same key as before it was called, since the key at slot 0
of leaf B (300 96 16) is less than the computed previous key, which is
(300 96 19);
6) As a consequence btrfs_previous_item() returns a path that points again
to the item with key (300 96 20).
For some users of btrfs_prev_leaf() or btrfs_previous_item() this may not
be functional a problem, despite not making sense to return a new path
pointing again to the same item/key. However for a caller such as
tree-log.c:log_dir_items(), this has a bad consequence, as it can result
in not logging some dir index deletions in case the directory is being
logged without holding the inode's VFS lock (logging triggered while
logging a child inode for example) - for the example scenario above, in
case the dir index keys 17, 18 and 19 were deleted in the current
transaction.

commit 631003e2333c12cc1b52df06a707365b7363a159 upstream.
find_next_bit and find_next_zero_bit take @size as the second parameter and
@offset as the third parameter. They are specified opposite in
btrfs_ensure_empty_zones(). Thanks to the later loop, it never failed to
detect the empty zones. Fix them and (maybe) return the result a bit
faster.
Note: the naming is a bit confusing, size has two meanings here, bitmap
and our range size.

commit 64b5d5b2852661284ccbb038c697562cc56231bf upstream.
[BUG]
With block-group-tree feature enabled, mounting it with clear_cache
would cause the following transaction abort at mount or remount:
BTRFS info (device dm-4): force clearing of disk cache
BTRFS info (device dm-4): using free space tree
BTRFS info (device dm-4): auto enabling async discard
BTRFS info (device dm-4): clearing free space tree
BTRFS info (device dm-4): clearing compat-ro feature flag for FREE_SPACE_TREE (0x1)
BTRFS info (device dm-4): clearing compat-ro feature flag for FREE_SPACE_TREE_VALID (0x2)
BTRFS error (device dm-4): block-group-tree feature requires fres-space-tree and no-holes
BTRFS error (device dm-4): super block corruption detected before writing it to disk
BTRFS: error (device dm-4) in write_all_supers:4288: errno=-117 Filesystem corrupted (unexpected superblock corruption detected)
BTRFS warning (device dm-4: state E): Skipping commit of aborted transaction.
[CAUSE]
For block-group-tree feature, we have an artificial dependency on
free-space-tree.
This means if we detect block-group-tree without v2 cache, we consider
it a corruption and cause the problem.
For clear_cache mount option, it would temporary disable v2 cache, then
re-enable it.
But unfortunately for that temporary v2 cache disabled status, we refuse
to write a superblock with bg tree only flag, thus leads to the above
transaction abortion.
[FIX]
For now, just reject clear_cache and v1 cache mount option for block
group tree. So now we got a graceful rejection other than a transaction
abort:
BTRFS info (device dm-4): force clearing of disk cache
BTRFS error (device dm-4): cannot disable free space tree with block-group-tree feature
BTRFS error (device dm-4): open_ctree failed

commit ac868bc9d136cde6e3eb5de77019a63d57a540ff upstream.
Balance as exclusive state is compatible with paused balance and device
add, which makes some things more complicated. The assertion of valid
states when starting from paused balance needs to take into account two
more states, the combinations can be hit when there are several threads
racing to start balance and device add. This won't typically happen when
the commands are started from command line.
Scenario 1: With exclusive_operation state == BTRFS_EXCLOP_NONE.
Concurrently adding multiple devices to the same mount point and
btrfs_exclop_finish executed finishes before assertion in
btrfs_exclop_balance, exclusive_operation will changed to
BTRFS_EXCLOP_NONE state which lead to assertion failed:
fs_info->exclusive_operation == BTRFS_EXCLOP_BALANCE ||
fs_info->exclusive_operation == BTRFS_EXCLOP_DEV_ADD,
in fs/btrfs/ioctl.c:456

commit e7db9e5c6b9615b287d01f0231904fbc1fbde9c5 upstream.
We have observed a btrfs filesystem corruption on workloads using
no-holes and encoded writes via send stream v2. The symptom is that a
file appears to be truncated to the end of its last aligned extent, even
though the final unaligned extent and even the file extent and otherwise
correctly updated inode item have been written.
So if we were writing out a 1MiB+X file via 8 128K extents and one
extent of length X, i_size would be set to 1MiB, but the ninth extent,
nbyte, etc. would all appear correct otherwise.
The source of the race is a narrow (one line of code) window in which a
no-holes fs has read in an updated i_size, but has not yet set a shared
disk_i_size variable to write. Therefore, if two ordered extents run in
parallel (par for the course for receive workloads), the following
sequence can play out: (following "threads" a bit loosely, since there
are callbacks involved for endio but extra threads aren't needed to
cause the issue)
ENC-WR1 (second to last) ENC-WR2 (last)
------- -------
btrfs_do_encoded_write
set i_size = 1M
submit bio B1 ending at 1M
endio B1
btrfs_inode_safe_disk_i_size_write
local i_size = 1M
falls off a cliff for some reason
btrfs_do_encoded_write
set i_size = 1M+X
submit bio B2 ending at 1M+X
endio B2
btrfs_inode_safe_disk_i_size_write
local i_size = 1M+X
disk_i_size = 1M+X
disk_i_size = 1M
btrfs_delayed_update_inode
btrfs_delayed_update_inode
And the delayed inode ends up filled with nbytes=1M+X and isize=1M, and
writes respect i_size and present a corrupted file missing its last
extents.
Fix this by holding the inode lock in the no-holes case so that a thread
can't sneak in a write to disk_i_size that gets overwritten with an out
of date i_size.

commit d246331b78cbef86237f9c22389205bc9b4e1cc1 upstream.
Boris noticed in his simple quotas testing that he was getting a leak
with Sweet Tea's change to subvol create that stopped doing a
transaction commit. This was just a side effect of that change.
In the delayed inode code we have an optimization that will free extra
reservations if we think we can pack a dir item into an already modified
leaf. Previously this wouldn't be triggered in the subvolume create
case because we'd commit the transaction, it was still possible but
much harder to trigger. It could actually be triggered if we did a
mkdir && subvol create with qgroups enabled.
This occurs because in btrfs_insert_delayed_dir_index(), which gets
called when we're adding the dir item, we do the following:
btrfs_block_rsv_release(fs_info, trans->block_rsv, bytes, NULL);
if we're able to skip reserving space.
The problem here is that trans->block_rsv points at the temporary block
rsv for the subvolume create, which has qgroup reservations in the block
rsv.
This is a problem because btrfs_block_rsv_release() will do the
following:
if (block_rsv->qgroup_rsv_reserved >= block_rsv->qgroup_rsv_size) {
qgroup_to_release = block_rsv->qgroup_rsv_reserved -
block_rsv->qgroup_rsv_size;
block_rsv->qgroup_rsv_reserved = block_rsv->qgroup_rsv_size;
}
The temporary block rsv just has ->qgroup_rsv_reserved set,
->qgroup_rsv_size == 0. The optimization in
btrfs_insert_delayed_dir_index() sets ->qgroup_rsv_reserved = 0. Then
later on when we call btrfs_subvolume_release_metadata() which has
btrfs_block_rsv_release(fs_info, rsv, (u64)-1, &qgroup_to_release);
btrfs_qgroup_convert_reserved_meta(root, qgroup_to_release);
qgroup_to_release is set to 0, and we do not convert the reserved
metadata space.
The problem here is that the block rsv code has been unconditionally
messing with ->qgroup_rsv_reserved, because the main place this is used
is delalloc, and any time we call btrfs_block_rsv_release() we do it
with qgroup_to_release set, and thus do the proper accounting.
The subvolume code is the only other code that uses the qgroup
reservation stuff, but it's intermingled with the above optimization,
and thus was getting its reservation freed out from underneath it and
thus leaking the reserved space.
The solution is to simply not mess with the qgroup reservations if we
don't have qgroup_to_release set. This works with the existing code as
anything that messes with the delalloc reservations always have
qgroup_to_release set. This fixes the leak that Boris was observing.

commit c83b56d1dd87cf67492bb770c26d6f87aee70ed6 upstream.
btrfs_redirty_list_add zeroes the buffer data and sets the
EXTENT_BUFFER_NO_CHECK to make sure writeback is fine with a bogus
header. But it does that after already marking the buffer dirty, which
means that writeback could already be looking at the buffer.
Switch the order of operations around so that the buffer is only marked
dirty when we're ready to write it.

From: Qu Wenruo <wqu@suse.com>
commit 1d6a4fc85717677e00fefffd847a50fc5928ce69 upstream.
Previously clear_cache mount option would simply disable free-space-tree
feature temporarily then re-enable it to rebuild the whole free space
tree.
But this is problematic for block-group-tree feature, as we have an
artificial dependency on free-space-tree feature.
If we go the existing method, after clearing the free-space-tree
feature, we would flip the filesystem to read-only mode, as we detect a
super block write with block-group-tree but no free-space-tree feature.
This patch would change the behavior by properly rebuilding the free
space tree without disabling this feature, thus allowing clear_cache
mount option to work with block group tree.
Now we can mount a filesystem with block-group-tree feature and
clear_mount option:
$ mkfs.btrfs -O block-group-tree /dev/test/scratch1 -f
$ sudo mount /dev/test/scratch1 /mnt/btrfs -o clear_cache
$ sudo dmesg -t | head -n 5

BTRFS info (device dm-1): using free space tree

commit 0004ff15ea26015a0a3a6182dca3b9d1df32e2b7 upstream.
When loading a free space cache from disk, at __load_free_space_cache(),
if we fail to insert a bitmap entry, we still increment the number of
total bitmaps in the btrfs_free_space_ctl structure, which is incorrect
since we failed to add the bitmap entry. On error we then empty the
cache by calling __btrfs_remove_free_space_cache(), which will result
in getting the total bitmaps counter set to 1.
A failure to load a free space cache is not critical, so if a failure
happens we just rebuild the cache by scanning the extent tree, which
happens at block-group.c:caching_thread(). Yet the failure will result
in having the total bitmaps of the btrfs_free_space_ctl always bigger
by 1 then the number of bitmap entries we have. So fix this by having
the total bitmaps counter be incremented only if we successfully added
the bitmap entry.

From: Filipe Manana <fdmanana@suse.com>
commit 0cad8f14d70cfeb5173dce93cafeba665a95430e upstream.
When using the logical to ino ioctl v2, if the flag to ignore offsets of
file extent items (BTRFS_LOGICAL_INO_ARGS_IGNORE_OFFSET) is given, the
backref walking code ends up not returning references for all file offsets
of an inode that point to the given logical bytenr. This happens since
kernel 6.2, commit 6ce6ba534418 ("btrfs: use a single argument for extent
offset in backref walking functions") because:
1) It mistakenly skipped the search for file extent items in a leaf that
point to the target extent if that flag is given. Instead it should
only skip the filtering done by check_extent_in_eb() - that is, it
should not avoid the calls to that function (or find_extent_in_eb(),
which uses it).
2) It was also not building a list of inode extent elements (struct
extent_inode_elem) if we have multiple inode references for an extent
when the ignore offset flag is given to the logical to ino ioctl - it
would leave a single element, only the last one that was found.
These stem from the confusing old interface for backref walking functions
where we had an extent item offset argument that was a pointer to a u64
and another boolean argument that indicated if the offset should be
ignored, but the pointer could be NULL. That NULL case is used by
relocation, qgroup extent accounting and fiemap, simply to avoid building
the inode extent list for each reference, as it's not necessary for those
use cases and therefore avoids memory allocations and some computations.
Fix this by adding a boolean argument to the backref walk context
structure to indicate that the inode extent list should not be built,
make relocation set that argument to true and fix the backref walking
logic to skip the calls to check_extent_in_eb() and find_extent_in_eb()
only if this new argument is true, instead of 'ignore_extent_item_pos'
being true.
A test case for fstests will be added soon, to provide cover not only
for these cases but to the logical to ino ioctl in general as well, as
currently we do not have a test case for it.

commit 0c0cd3e25a5b64b541dd83ba6e032475a9d77432 upstream.
I had incorrectly thought that PSC profiles were not usable on Intel
platforms so had blocked them in the driver initialistion. This broke
platform profiles on the T490.
After discussion with the FW team PSC does work on Intel platforms and
should be allowed.
Note - it's possible this may impact other platforms where it is advertised
but special driver support that only Windows has is needed. But if it does
then they will need fixing via quirks. Please report any issues to me so I
can get them addressed - but I haven't found any problems in testing...yet

commit 1684878952929e20a864af5df7b498941c750f45 upstream.
There has been a lot of confusion around which platform profiles are
supported on various platforms and it would be useful to have a debug
method to be able to override the profile mode that is selected.
I don't expect this to be used in anything other than debugging in
conjunction with Lenovo engineers - but it does give a way to get a
system working whilst we wait for either FW fixes, or a driver fix
to land upstream, if something is wonky in the mode detection logic

commit c915d8f5918bea7c3962b09b8884ca128bfd9b0c upstream.
When inotify_freeing_mark() races with inotify_handle_inode_event() it
can happen that inotify_handle_inode_event() sees that i_mark->wd got
already reset to -1 and reports this value to userspace which can
confuse the inotify listener. Avoid the problem by validating that wd is
sensible (and pretend the mark got removed before the event got
generated otherwise).

From: Steve French <stfrench@microsoft.com>
commit 2cb6f968775a9fd60c90a6042b9550bcec3ea087 upstream.
In investigating a failure with xfstest generic/392 it
was noticed that mounts were reusing a superblock that should
already have been freed. This turned out to be related to
deferred close files keeping a reference count until the
closetimeo expired.
Currently the only way an fs knows that mount is beginning is
when force unmount is called, but when this, ie umount_begin(),
is called all deferred close files on the share (tree
connection) should be closed immediately (unless shared by
another mount) to avoid using excess resources on the server
and to avoid reusing a superblock which should already be freed.
In umount_begin, close all deferred close handles for that
share if this is the last mount using that share on this
client (ie send the SMB3 close request over the wire for those
that have been already closed by the app but that we have
kept a handle lease open for and have not sent closes to the
server for yet).

From: Randy Dunlap <rdunlap@infradead.org>
commit d1155e4132de712a9d3066e2667ceaad39a539c5 upstream.
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from nmi_debug_setup().

From: Luis Chamberlain <mcgrof@kernel.org>
commit 67ff32289acad9ed338cd9f2351b44939e55163e upstream.
Update the docs for __register_sysctl_table() to make it clear no child
entries can be passed. When the child is true these are non-leaf entries
on the ctl table and sysctl treats these as directories. The point to
__register_sysctl_table() is to deal only with directories not part of
the ctl table where thay may riside, to be simple and avoid recursion.
While at it, hint towards using long on extra1 and extra2 later.

commit 5ef074e805ecfd9a16dbb7b6b88bbfa8abad7054 upstream.
Function of_phandle_iterator_next() calls of_node_put() on the last
device_node it iterated over, but when the loop exits prematurely it has
to be called explicitly.

commit 228b09de936395ddd740df3522ea35ae934830d8 upstream.
Relatively new docs which I added which hinted the base directories needed
to be created before is wrong, remove that incorrect comment. This has been
hinted before by Eric twice already [0] [1], I had just not verified that
until now. Now that I've verified that updates the docs to relax the context
described.

While I'm not aware of any problems that have occurred running these
at 100 MHz, the official word from ASRock is that 50 MHz is the
correct speed to use, so let's be safe and use that instead.

From: Johan Hovold <johan+linaro@kernel.org>
commit 0d997f95b70f98987ae031a89677c13e0e223670 upstream.
A recent commit moved enabling of runtime PM to GPU load time (first
open()) but failed to update the error paths so that runtime PM is
disabled if initialisation of the GPU fails. This would trigger a
warning about the unbalanced disable count on the next open() attempt.
Note that pm_runtime_put_noidle() is sufficient to balance the usage
count when pm_runtime_put_sync() fails (and is chosen over
pm_runtime_resume_and_get() for consistency reasons).

Since commit c3b790ea07a1 ("drm: Manage drm_mode_config_init with

also when using the legacy interface, but add an explicit cleanup for
consistency and to facilitate backporting.

From: Hans de Goede <hdegoede@redhat.com>
commit c8c2969bfcba5fcba3a5b078315c1b586d927d9f upstream.
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have
a version of 3 or newer and the panel is in vid-mode.
This is based on the big comment around line 730 which starts with
"Panel enable/disable sequences from the VBT spec.", where
the "v3 video mode seq" column does not have any wait t# entries.
Checking the Windows driver shows that it does always honor
the VBT delays independent of the version of the VBT sequences.
Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for
the panel_on_delay when there is no reset-deassert MIPI-sequence")
switched to a direct msleep() instead of intel_dsi_msleep()
when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix
the panel on an Acer Aspire Switch 10 E SW3-016 not turning on.
And now testing on a Nextbook Ares 8A shows that panel_on_delay
must always be honored otherwise the panel will not turn on.
Instead of only always using regular msleep() for panel_on_delay
do as Windows does and always use regular msleep() everywhere
were intel_dsi_msleep() is used and drop the intel_dsi_msleep()
helper.
Changes in v2:
- Replace all intel_dsi_msleep() calls instead of just
the intel_dsi_msleep(panel_on_delay) call

commit 043d2d00b44310f84c0593c63e51fae88c829cdd upstream.
Let's reduce the complexity of mixed use of rb_tree in victim_entry from
extent_cache and discard_cmd.
This should fix arm32 memory alignment issue caused by shared rb_entry.

commit 48ce2d722f7f108f27bedddf54bee3423a57ce57 upstream.
For dual-bridges scenario, pch_pic_acpi_init() will be called
in following path:
cpuintc_acpi_init
acpi_cascade_irqdomain_init(in cpuintc driver)
acpi_table_parse_madt
eiointc_parse_madt
eiointc_acpi_init /* this will be called two times
correspondingto parsing two
eiointc entries in MADT under
dual-bridges scenario*/
acpi_cascade_irqdomain_init(in eiointc driver)
acpi_table_parse_madt
pch_pic_parse_madt
pch_pic_acpi_init /* this will be called depend
on valid parent IRQ domain
handle for one or two times
corresponding to parsing
two pchpic entries in MADT
druring calling
eiointc_acpi_init() under
dual-bridges scenario*/
During the first eiointc_acpi_init() calling, the
pch_pic_acpi_init() will be called just one time since only
one valid parent IRQ domain handle will be found for current
eiointc IRQ domain.
During the second eiointc_acpi_init() calling, the
pch_pic_acpi_init() will be called two times since two valid
parent IRQ domain handles will be found. So in pch_pic_acpi_init(),
we must have a reasonable way to prevent from creating second same
pch_pic IRQ domain.
The patch matches gsi base information in created pch_pic IRQ
domains to check if the target domain has been created to avoid the
bug mentioned above.

commit 112eaa8fec5ea75f1be003ec55760b09a86799f8 upstream.
In pch_pic_parse_madt(), a NULL parent pointer will be
returned from acpi_get_vec_parent() for second pch-pic domain
related to second bridge while calling eiointc_acpi_init() at
first time, where the parent of it has not been initialized
yet, and will be initialized during second time calling
eiointc_acpi_init(). So, it's reasonable to return zero so
that failure of acpi_table_parse_madt() will be avoided, or else
acpi_cascade_irqdomain_init() will return and initialization of
followed pch_msi domain will be skipped.
Although it does not matter when pch_msi_parse_madt() returns
-EINVAL if no invalid parent is found, it's also reasonable to
return zero for that.

commit 64cc451e45e146b2140211b4f45f278b93b24ac0 upstream.
In eiointc_acpi_init(), a *eiointc* node is passed into
acpi_get_vec_parent() instead of a required *NUMA* node (on some chip
like 3C5000L, a *NUMA* node means a *eiointc* node, but on some chip
like 3C5000, a *NUMA* node contains 4 *eiointc* nodes), and node in
struct acpi_vector_group is essentially a *NUMA* node, which will
lead to no parent matched for passed *eiointc* node. so the patch
adjusts code to use *NUMA* node for parameter node of
acpi_set_vec_parent/acpi_get_vec_parent.

commit ab4f869fba6119997f7630d600049762a2b014fa upstream.
This is the logical place to put the backlight device, and it also
fixes a kernel crash if the MIPI host is removed. Previously the
backlight device would be unregistered twice when this happened - once
as a child of the MIPI host through `mipi_dsi_host_unregister`, and
once when the panel device is destroyed.

commit d29fb7baab09b6a1dc484c9c67933253883e770a upstream.
[Why]
While scanning the top_pipe connections we can run into a case where
the bottom pipe is still connected to a top_pipe but with a NULL
plane_state.
[How]
Treat a NULL plane_state the same as the plane being invisible for
pipe cursor disable logic.

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
commit bf224e00a9f54e2bf14b4d720a09c3d2f4aa4aa8 upstream.
[Why]
DPP Root clock optimization when combined with 4to1 MPC combine results
in the screen turning black.
This is because the DPPCLK is stopped during the middle of an
optimize_bandwidth sequence during commit_minimal_transition without
going through plane power down/power up.
[How]
The intent of a 0Hz DPP clock through update_clocks is to disable the
DTO. This differs from the behavior of stopping the DPPCLK entirely
(utilizing a 0Hz clock on some ASIC) so it's better to move this logic
to reside next to plane power up/power down where we gate the HUBP/DPP
DOMAIN.
The new sequence should be:
Power down: PG enabled -> RCO on
Power up: RCO off -> PG disabled
Rename power_on_plane to power_on_plane_resources to reflect the
actual operation that's occurring.

commit 682439fffad9fa9a38d37dd1b1318e9374232213 upstream.
[Why]
Reading pipe_fuses from register may have invalid bits set, which may
affect the num_pipes erroneously.
[How]
Add read_pipes_fuses() call and filter bits based on expected number
of pipes.

commit 08da182175db4c7f80850354849d95f2670e8cd9 upstream.
Currently, on a handful of ASICs. We allow the framebuffer for a given
plane to exist in either VRAM or GTT. However, if the plane's new
framebuffer is in a different memory domain than it's previous
framebuffer, flipping between them can cause the screen to flicker. So,
to fix this, don't perform an immediate flip in the aforementioned case.

commit 1253685f0d3eb3eab0bfc4bf15ab341a5f3da0c8 upstream.
Once command submission failed due to userptr invalidation in
amdgpu_cs_submit, legacy code will perform cleanup of scheduler
job. However, it's not needed at all, as former commit has integrated
job cleanup stuff into amdgpu_job_free. Otherwise, because of double
free, a NULL pointer dereference will occur in such scenario.

commit 08c677cb0b436a96a836792bb35a8ec5de4999c2 upstream.
The gmc.ecc_irq is enabled by firmware per IFWI setting,
and the host driver is not privileged to enable/disable
the interrupt. So, it is meaningless to use the amdgpu_irq_put
function in gmc_v10_0_hw_fini, which also leads to the call
trace.

commit 922a76ba31adf84e72bc947267385be420c689ee upstream.
As made mention of in commit 08c677cb0b43 ("drm/amdgpu: fix
amdgpu_irq_put call trace in gmc_v10_0_hw_fini") and commit 13af556104fa
("drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v11_0_hw_fini"). It
is meaningless to call amdgpu_irq_put() for gmc.ecc_irq. So, remove it
from gmc_v9_0_hw_fini().

commit 4a76680311330aefe5074bed8f06afa354b85c48 upstream.
gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert.
So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq
should be executed under such condition, otherwise, an amdgpu_irq_put
calltrace will occur.

commit b504f99ccaa64da364443431e388ecf30b604e38 upstream.
[Description]
- Due to bandwidth / arbitration issues at 200Mhz DCFCLK,
we want to enforce minimum 60us of prefetch to avoid
intermittent underflow issues
- Since 60us prefetch is already enforced for UCLK DPM0,
and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in
theory there should not be any UCLK DPM regressions by
enforcing greater prefetch

commit 58d9b9a14b47c2a3da6effcbb01607ad7edc0275 upstream.
amdgpu_dpm_is_overdrive_supported is a common API across all
asics, so we should cast pp_handle into correct structure
under different power frameworks.
v2: using return directly to simplify code
v3: SI asic does not carry od_enabled member in pp_handle, and update Fixes tag

commit 8b229ada2669b74fdae06c83fbfda5a5a99fc253 upstream.
sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini,
driver unconditionally disables ecc_irq which is only enabled on
those asics enabling sdma ecc. This will introduce a warning in
suspend cycle on those chips with sdma ip v4.0, while without
sdma ecc. So this patch correct this.

commit cc42e76e7de5190a7da5dac9d7b2bbb458e050bf upstream.
Add an early_init phase to MES for fetching and validating microcode
from the filesystem.
If MES microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.
Move the request for MES microcode into the early_init phase
so that if it's not available, early_init will fail.

commit 2210af50ae7f4104269dfde7bafbbfbacdbe1a2b upstream.
All microcode runs a basic validation after it's been loaded. Each
IP block as part of init will run both.
Introduce a wrapper for request_firmware and amdgpu_ucode_validate.
This wrapper will also remap any error codes from request_firmware
to -ENODEV. This is so that early_init will fail if firmware couldn't
be loaded instead of the IP block being disabled.

The `amdgpu_ucode_request` helper will ensure that the return code for

The `amdgpu_ucode_release` helper provides symmetry for releasing firmware.

From: Ping Cheng <pinglinux@gmail.com>
commit 17d793f3ed53080dab6bbeabfc82de890c901001 upstream.
To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.
This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

commit 3eeca5e5f3100435b06a5b5d86daa3d135a8a4bd upstream.
The adreno_load_gpu() path is guarded by an error check on
adreno_load_fw(). This function is responsible for loading
Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it
does not take the vendor-signed ZAP blob into account.
By embedding the SQE (and GMU, if necessary) firmware into the
initrd/kernel, we can trigger and unfortunate path that would not bail
out early and proceed with gpu->hw_init(). That will fail, as the ZAP
loader path will not find the firmware and return back to
adreno_load_gpu().
This error path involves pm_runtime_put_sync() which then calls idle()
instead of suspend(). This is suboptimal, as it means that we're not
going through the clean shutdown sequence. With at least A619_holi, this
makes the GPU not wake up until it goes through at least one more
start-fail-stop cycle. The pm_runtime_put_sync that appears in the error
path actually does not guarantee that because of the earlier enabling of
runtime autosuspend.
Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown.
Test cases:
1. All firmware baked into kernel
2. error loading ZAP fw in initrd -> load from rootfs at DE start
Both succeed on A619_holi (SM6375) and A630 (SDM845).

[ Upstream commit 81900e3a37750d8c6ad705045310e002f6dd0356 ]
By default the indirect state sampler data (border colors) are stored
in the same heap as the SAMPLER_STATE structure. For userspace drivers
that can be 2 different heaps (dynamic state heap & bindless sampler
state heap). This means that border colors have to copied in 2
different places so that the same SAMPLER_STATE structure find the
right data.
This change is forcing the indirect state sampler data to only be in
the dynamic state pool (more convenient for userspace drivers, they
only have to have one copy of the border colors). This is reproducing
the behavior of the Windows drivers.

This patch is only relevant for MTL, which is not fully supported on
v6.2 yet, so I don't think we need to cherry-pick it to v6.2.

Does it break anything on 6.2? If not, I think you want it as it is a
dependancy for another fix, right?

Ah, I missed the dependency link there. I was about to write that it
doesn't _hurt_ to take it, just thought it was irrelevant.
So, this patch _can_ be taken if something else depends on it.

[ Upstream commit d944eafed618a8507270b324ad9d5405bb7f0b3e ]
The skl+ scalers only sample 12 bits of PIPESRC so we can't
do any plane scaling at all when the pipe source size is >4k.
Make sure the pipe source size is also below the scaler's src
size limits. Might not be 100% accurate, but should at least be
safe. We can refine the limits later if we discover that recent
hw is less restricted.

screen only.
[How]
Remove multi display support, restrict number of planes for all

[ Upstream commit 0215ce9057edf69aff9c1a32f4254e1ec297db31 ]
[Why]
Block periods that are too short as they have the potential to
currently cause hangs in other firmware components on the system.
[How]
Update the threshold, mostly targeting a block of 4k and downscaling.

[ Upstream commit 13525645e2246ebc8a21bd656248d86022a6ee8f ]
The operator precedence between << and & is wrong, leading to the high
byte being completely ignored. For example, with the 6.4 format, 32
becomes 0 and 24 becomes 8. Fix it, and remove the slightly confusing
and unnecessary DP_DSC_MAX_BITS_PER_PIXEL_HI_SHIFT macro while at it.

commit 92cc5d00a431e96e5a49c0b97e5ad4fa7536bd4b upstream.
Apparently despite it being marked inline, the compiler
may not inline __down_read_common() which makes it difficult
to identify the cause of lock contention, as the blocked
function in traceevents will always be listed as
__down_read_common().
So this patch adds __always_inline annotation to the common
function (as well as the inlined helper callers) to force it to
be inlined so the blocking function will be listed (via Wchan)
in traceevents.

Acctually, blocks per group is 64, but block bitmap indicate at least has
128 blocks. Now, ext4_validate_block_bitmap() didn't check invalid block's
bitmap if set.
To resolve above issue, add check like fsck "Padding at end of block bitmap is
not set".

Replace
le16_to_cpu(sbi->s_es->s_desc_size)
with
sbi->s_desc_size
It reduces ext4's compiled text size, and makes the code more efficient
(we remove an extra indirect reference and a potential byte
swap on big endian systems), and there is no downside. It also avoids the
potential KASAN / syzkaller failure, as a bonus.

commit 492888df0c7b42fc0843631168b0021bc4caee84 upstream.
When using cached extent stored in extent status tree in tree->cache_es
another process holding ei->i_es_lock for reading can be racing with us
setting new value of tree->cache_es. If the compiler would decide to
refetch tree->cache_es at an unfortunate moment, it could result in a
bogus in_range() check. Fix the possible race by using READ_ONCE() when
using tree->cache_es only under ei->i_es_lock for reading.

commit 00d873c17e29cc32d90ca852b82685f1673acaa5 upstream.
Ext4 has a filesystem wide lock protecting ext4_writepages() calls to
avoid races with switching of journalled data flag or inode format. This
lock can however cause a deadlock like:
CPU0 CPU1
ext4_writepages()
percpu_down_read(sbi->s_writepages_rwsem);
ext4_change_inode_journal_flag()
percpu_down_write(sbi->s_writepages_rwsem);
- blocks, all readers block from now on
ext4_do_writepages()
ext4_init_io_end()
kmem_cache_zalloc(io_end_cachep, GFP_KERNEL)
fs_reclaim frees dentry...
dentry_unlink_inode()
iput() - last ref =>
iput_final() - inode dirty =>
write_inode_now()...
ext4_writepages() tries to acquire sbi->s_writepages_rwsem
and blocks forever
Make sure we cannot recurse into filesystem reclaim from writeback code
to avoid the deadlock.

From: Baokun Li <libaokun1@huawei.com>
commit fa83c34e3e56b3c672af38059e066242655271b1 upstream.
When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may
fail for some reason (e.g. memory allocation failure, bare disk write), and
later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4
iomap_begin() returns an error, it is normal that the type of iomap->type
may not match the expectation. Therefore, we only determine if iomap->type
is as expected when ext4_iomap_begin() is executed successfully.

commit 4c0b4818b1f636bc96359f7817a2d8bab6370162 upstream.
If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.
This commit fixes two problem. The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free. The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

commit 4b3cb1d108bfc2aebb0d7c8a52261a53cf7f5786 upstream.
The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced. However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.
So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.

directory lock. There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.
A simple reproducer demonstrating the problem:
mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
mount -t ext4 -o dirsync /dev/vdc /vdc
cd /vdc
mkdir file0
cd file0
touch file0
touch file1
attr -s BurnSpaceInEA -V abcde .
touch supercalifragilisticexpialidocious

commit 2220eaf90992c11d888fe771055d4de330385f01 upstream.
Normally the extended attributes in the inode body would have been
checked when the inode is first opened, but if someone is writing to
the block device while the file system is mounted, it's possible for
the inode table to get corrupted. Add bounds checking to avoid
reading beyond the end of allocated memory if this happens.

commit 949f95ff39bf188e594e7ecd8e29b82eb108f5bf upstream.
When we enable MMP in ext4_multi_mount_protect() during mount or
remount, we end up calling sb_start_write() from write_mmp_block(). This
triggers lockdep warning because freeze protection ranks above s_umount
semaphore we are holding during mount / remount. The problem is harmless
because we are guaranteed the filesystem is not frozen during mount /
remount but still let's fix the warning by not grabbing freeze
protection from ext4_multi_mount_protect().

If a malicious fuzzer overwrites the ext4 superblock while it is
mounted such that the s_first_data_block is set to a very large
number, the calculation of the block group can underflow, and trigger
a BUG_ON check. Change this to be an ext4_warning so that we don't
crash the kernel.

From: Theodore Ts'o <tytso@mit.edu>
commit b87c7cdf2bed4928b899e1ce91ef0d147017ba45 upstream.
In ext4_xattr_move_to_block(), the value of the extended attribute
which we need to move to an external block may be allocated by
kvmalloc() if the value is stored in an external inode. So at the end
of the function the code tried to check if this was the case by
testing entry->e_value_inum.
However, at this point, the pointer to the xattr entry is no longer
valid, because it was removed from the original location where it had
been stored. So we could end up calling kvfree() on a pointer which
was not allocated by kvmalloc(); or we could also potentially leak
memory by not freeing the buffer when it should be freed. Fix this by
storing whether it should be freed in a separate variable.

310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")
switched to using amd_smn_read() which relies upon the misc PCI ID used
by DF function 3 being included in a table. The ID for model 78h is
missing in that table, so amd_smn_read() doesn't work.
Add the missing ID into amd_nb, restoring s2idle on this system.

From: Linus Torvalds <torvalds@linux-foundation.org>
This code no longer exists in mainline, because it was removed in
commit d2c95f9d6802 ("x86: don't use REP_GOOD or ERMS for user memory
clearing") upstream.
However, rather than backport the full range of x86 memory clearing and
copying cleanups, fix the exception table annotation placement for the
final 'rep movsb' in clear_user_rep_good(): rather than pointing at the
actual instruction that did the user space access, it pointed to the
register move just before it.
That made sense from a code flow standpoint, but not from an actual
usage standpoint: it means that if user access takes an exception, the
exception handler won't actually find the instruction in the exception
tables.
As a result, rather than fixing it up and returning -EFAULT, it would
then turn it into a kernel oops report instead, something like:
BUG: unable to handle page fault for address: 0000000020081000
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

commit 8a5299a1278eadf1e08a598a5345c376206f171e upstream.
For different reasons, fsl-spi driver performs bits_per_word
modifications for different reasons:
- On CPU mode, to minimise amount of interrupts
- On CPM/QE mode to work around controller byte order
For CPU mode that's done in fsl_spi_prepare_message() while
for CPM mode that's done in fsl_spi_setup_transfer().
Reunify all of it in fsl_spi_prepare_message(), and catch
impossible cases early through master's bits_per_word_mask
instead of returning EINVAL later.

From: Christophe Leroy <christophe.leroy@csgroup.eu>
commit fc96ec826bced75cc6b9c07a4ac44bbf651337ab upstream.
On CPM, the RISC core is a lot more efficiant when doing transfers
in 16-bits chunks than in 8-bits chunks, but unfortunately the
words need to be byte swapped as seen in a previous commit.
So, for large tranfers with an even size, allocate a temporary tx
buffer and byte-swap data before and after transfer.
This change allows setting higher speed for transfer. For instance
on an MPC 8xx (CPM1 comms RISC processor), the documentation tells
that transfer in byte mode at 1 kbit/s uses 0.200% of CPM load
at 25 MHz while a word transfer at the same speed uses 0.032%
of CPM load. This means the speed can be 6 times higher in
word mode for the same CPM load.
For the time being, only do it on CPM1 as there must be a
trade-off between the CPM load reduction and the CPU load required
to byte swap the data.
