commit 1039188806d4cfdf9c412bb4ddb51b4d8cd15478 upstream.
This reverts commit 4b7786d87fb3adf3e534c4f1e4f824d8700b786b.
Commit 4b7786d87fb3 ("drm/amd/display: Fix DCN3 B0 DP Alt Mapping")
is causing 2nd USB-C display not lighting up.
Phy id remapping is done differently than is assumed in this
patch.

There is a header for a DB9 serial port, but any attempts to use
hardware handshaking fail. Enable RTS and CTS pin muxing and enable
handshaking in the uart node.

From: Jens Axboe <axboe@kernel.dk>
commit 9cae36a094e7e9d6e5fe8b6dcd4642138b3eb0c7 upstream.
After some debugging, it was realized that we really do still need the
old inflight tracking for any file type that has io_uring_fops assigned.
If we don't, then trivial circular references will mean that we never get
the ctx cleaned up and hence it'll leak.
Just bring back the inflight tracking, which then also means we can
eliminate the conditional dropping of the file when task_work is queued.
Fixes: d5361233e9ab ("io_uring: drop the old style inflight file tracking")

After looking into this issue, I find the buggy address belongs
to the task stack region. It seems KASAN has something wrong.
I look into the code of __get_wchan in x86 architecture and
find the same issue has been resolved by the commit
f7d27c35ddff ("x86/mm, kasan: Silence KASAN warnings in get_wchan()").
The solution could be applied to powerpc architecture too.
As Andrey Ryabinin said, get_wchan() is racy by design, it may
access volatile stack of running task, thus it may access
redzone in a stack frame and cause KASAN to warn about this.
Use READ_ONCE_NOCHECK() to silence these warnings.

[ Upstream commit aeca8a3295022bcec46697f16e098140423d8463 ]
We tried to enable the audio on an imx6sx EVB with the codec nau8822,
after setting the internal PLL fractional parameters, the audio still
couldn't work and the there was no sdma irq at all.
After checking with the section "8.1.1 Phase Locked Loop (PLL) Design
Example" of "NAU88C22 Datasheet Rev 0.6", we found we need to
turn off the PLL before programming fractional parameters and turn on
the PLL after programming.
After this change, the audio driver could record and play sound and
the sdma's irq is triggered when playing or recording.

[Why]
Dmub read AUX_DPHY_RX_CONTROL0 from Golden Setting Table,
but driver will set it to default value 0x103d1110, which
causes issue in some case
[How]
Remove the driver code, use the value set by dmub in

Limit the error msg to avoid flooding the console. If you have a lot of
threads hitting this at once, they could have already gotten passed the
dma_debug_disabled() check before they get to the point of allocation
failure, resulting in quite a lot of this error message spamming the
log. Use pr_err_once() to limit that.

The datasheet specifies the range of the mixer volumes as between
-51.5dB and 12dB with a 0.5dB step. Update the TLVs for this.

A couple of the SX volume controls specify 0x84 as the lowest volume
value, however the correct value from the datasheet is 0x44. The
datasheet don't include spaces in the value it displays as binary so
this was almost certainly just a typo reading 1000100.

The minimum value for the PGA Volume is given as 0x1A, however the
values from there to 0x19 are all the same volume and this is not
represented in the TLV structure. The number of volumes given is correct
so this leads to all the volumes being shifted. Move the minimum value
up to 0x19 to fix this.

The kfd_bo_list is used to restore process BOs after
evictions. As page tables could be destroyed during
evictions, we should also update pinned BOs' page tables
during restoring to make sure they are valid.
So for pinned BOs,
1, Validate them and update their page tables.
2, Don't add eviction fence for them.
v2:
- Don't handle pinned ones specially in BO validation.(Felix)

[ Upstream commit bf476fe22aa1851bab4728e0c49025a6a0bea307 ]
In an unlikely (and probably wrong?) case that the 'ppi' parameter of
ata_host_alloc_pinfo() points to an array starting with a NULL pointer,
there's going to be a kernel oops as the 'pi' local variable won't get
reassigned from the initial value of NULL. Initialize 'pi' instead to
'&ata_dummy_port_info' to fix the possible kernel oops for good...

As described in commit 02117b8ae9c0 ("f2fs: Set GF_NOFS in
read_cache_page_gfp while doing f2fs_quota_read"), we must not enter
filesystem reclaim while holding the dq_lock. Prevent this more generally
by using memalloc_nofs_save() while holding the lock.

If the audio CODEC is playing sound when the system is suspended,
it can be left in a state which throws the following error:
wm8962 3-001a: ASoC: error at soc_component_read_no_lock on wm8962.3-001a: -16
Once this error has occurred, the audio will not work again until rebooted.
Fix this by configuring SET_SYSTEM_SLEEP_PM_OPS.

Currently the put() method for the deemphasis control returns 0 when a new
value is written to the control even if the value changed, meaning events
are not generated. Fix this, skip the work of updating the value when it is
unchanged and then return 1 after having done so.

Currently wm_adsp_fw_put() returns 0 rather than 1 when updating the value
of the control, meaning that no event is generated to userspace. Fix this
by setting the default return value to 1, the code already exits early with
a return value of 0 if the value is unchanged.

Commit 223f61b8c5ad ("Input: soc_button_array - add Lenovo Yoga Tablet2
1051L to the dmi_use_low_level_irq list") added the 1051L to this list
already, but the same problem applies to the 1051F. As there are no
further 1051 variants (just the F/L), we can just DMI match 1051.
Tested on a Lenovo Yoga Tablet2 1051F: Without this patch the
home-button stops working after a wakeup from suspend.

[ Upstream commit cf71d59c2eceadfcde0fb52e237990a0909880d7 ]
vcpuHint has been expanded to 16 bit on host to enable routing to more
CPUs. Guest side should align with the change. This change has been tested
with hosts with 8-bit and 16-bit vcpuHint, on both platforms host side can
get correct value.

[ Upstream commit b1b3440f437b75fb2a9b0cfe58df461e40eca474 ]
A use-after-free crash can occur after an ELS LOGO is aborted.
Specifically, a nodelist structure is freed and then
ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the
discovery state machine is mistakenly called a second time with
NLP_EVT_DEVICE_RM argument.
Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a
nodelist structure.

[ Upstream commit 336d63615466b4c06b9401c987813fd19bdde39b ]
After issuing a LIP, a specific target vendor does not ACC the FLOGI that
lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The
target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs
and starts the RPI registration for DID 0x000001. The target then sends a
LOGO to the fabric DID. lpfc is currently treating the LOGO from the
fabric DID as a link down and cleans up all the ndlps. The ndlp for DID
0x000001 is put back into NPR and discovery stops, leaving the port in
stuck in bypassed mode.
Change lpfc behavior such that if a LOGO is received for the fabric DID in
PT2PT topology skip the lpfc_linkdown_port() routine and just move the
fabric DID back to NPR.

[ Upstream commit 120f1d95efb1cdb6fe023c84e38ba06d8f78cd03 ]
I'm facing this warning when building for the parisc64 architecture:
drivers/scsi/mpt3sas/mpt3sas_base.c: In function ‘_base_make_ioc_operational’:
drivers/scsi/mpt3sas/mpt3sas_base.c:5396:40: warning: array subscript ‘Mpi2SasIOUnitPage1_t {aka struct _MPI2_CONFIG_PAGE_SASIOUNIT_1}[0]’ is partly outside array bounds of ‘unsigned char[20]’ [-Warray-bounds]
5396 | (le16_to_cpu(sas_iounit_pg1->SASWideMaxQueueDepth)) ?
drivers/scsi/mpt3sas/mpt3sas_base.c:5382:26: note: referencing an object of size 20 allocated by ‘kzalloc’
5382 | sas_iounit_pg1 = kzalloc(sz, GFP_KERNEL);
| ^~~~~~~~~~~~~~~~~~~~~~~
The problem is, that only 20 bytes are allocated with kmalloc(), which is
sufficient to hold the bytes which are needed. Nevertheless, gcc complains
because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus
doesn't fit into those 20 bytes.
This patch simply allocates all 32 bytes (instead of 20) and thus avoids
the warning. There is no functional change introduced by this patch.
While touching the code I cleaned up to calculation of max_wideport_qd,
max_narrowport_qd and max_sata_qd to make it easier readable.
Test successfully tested on a HP C8000 PA-RISC workstation with 64-bit
kernel.

[ Upstream commit 8a4d480702b71184fabcf379b80bf7539716752e ]
Similar to the handling of play_deferred in commit 19cfe912c37b
("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought
a patch might be needed here as well.
Currently usb_submit_urb is called directly to submit deferred tx
urbs after unanchor them.
So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak.
Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be
overflow. To fix, we can follow what udpv6 does and subtract the

[ Upstream commit 49beadbd47c270a00754c107a837b4f29df4c822 ]
While the concept of checking for dangling pointers to local variables
at function exit is really interesting, the gcc-12 implementation is not
compatible with reality, and results in false positives.
For example, gcc sees us putting things on a local list head allocated
on the stack, which involves exactly those kinds of pointers to the
local stack entry:
In function ‘__list_add’,
inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
74 | new->prev = prev;
| ~~~~~~~~~~^~~~~~
But then gcc - understandably - doesn't really understand the big
picture how the doubly linked list works, so doesn't see how we then end
up emptying said list head in a loop and the pointer we added has been
removed.
Gcc also complains about us (intentionally) using this as a way to store
a kind of fake stack trace, eg
drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
40 | acpi_gbl_entry_stack_pointer = ¤t_sp;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
which is entirely reasonable from a compiler standpoint, and we may want
to change those kinds of patterns, but not not.
So this is one of those "it would be lovely if the compiler were to
complain about us leaving dangling pointers to the stack", but not this
way.

[ Upstream commit 842c3b3ddc5f4d17275edbaa09e23d712bf8b915 ]
gcc-12 started warning about 'tracker' being used uninitialized:
drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c: In function ‘mlx5_do_bond’:
drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized]
786 | struct lag_tracker tracker;
| ^~~~~~~
which seems to be because it doesn't track how the use (and
initialization) is bound by the 'do_bond' flag.
But admittedly that 'do_bond' usage is fairly complicated, and involves
passing it around as an argument to helper functions, so it's somewhat
understandable that gcc doesn't see how that all works.
This function could be rewritten to make the use of that tracker
variable more obviously safe, but for now I'm just adding the forced
initialization of it.

[ Upstream commit f0be87c42cbd341d436d06da4792e6b0c83c3aeb ]
In commit 8b202ee21839 ("s390: disable -Warray-bounds") the s390 people
disabled the '-Warray-bounds' warning for gcc-12, because the new logic
in gcc would cause warnings for their use of the S390_lowcore macro,
which accesses absolute pointers.
It turns out gcc-12 has many other issues in this area, so this takes
that s390 warning disable logic, and turns it into a kernel build config
entry instead.
Part of the intent is that we can make this all much more targeted, and
use this conflig flag to disable it in only particular configurations
that cause problems, with the s390 case as an example:
select GCC12_NO_ARRAY_BOUNDS
and we could do that for other configuration cases that cause issues.
Or we could possibly use the CONFIG_CC_NO_ARRAY_BOUNDS thing in a more
targeted way, and disable the warning only for particular uses: again
the s390 case as an example:
KBUILD_CFLAGS_DECOMPRESSOR += $(if $(CONFIG_CC_NO_ARRAY_BOUNDS),-Wno-array-bounds)
but this ends up just doing it globally in the top-level Makefile, since
the current issues are spread fairly widely all over:
KBUILD_CFLAGS-$(CONFIG_CC_NO_ARRAY_BOUNDS) += -Wno-array-bounds
We'll try to limit this later, since the gcc-12 problems are rare enough
that *much* of the kernel can be built with it without disabling this
warning.

[ Upstream commit 507160f46c55913955d272ebf559d63809a8e560 ]
This is a pure band-aid so that I can continue merging stuff from people
while some of the gcc-12 fallout gets sorted out.
In particular, gcc-12 is very unhappy about the kinds of pointer
arithmetic tricks that netfs does, and that makes the fortify checks
trigger in afs and ceph:
In function ‘fortify_memset_chk’,
inlined from ‘netfs_i_context_init’ at include/linux/netfs.h:327:2,
inlined from ‘afs_set_netfs_context’ at fs/afs/inode.c:61:2,
inlined from ‘afs_root_iget’ at fs/afs/inode.c:543:2:
include/linux/fortify-string.h:258:25: warning: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
258 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
and the reason is that netfs_i_context_init() is passed a 'struct inode'
pointer, and then it does
struct netfs_i_context *ctx = netfs_i_context(inode);
memset(ctx, 0, sizeof(*ctx));
where that netfs_i_context() function just does pointer arithmetic on
the inode pointer, knowing that the netfs_i_context is laid out
immediately after it in memory.
This is all truly disgusting, since the whole "netfs_i_context is laid
out immediately after it in memory" is not actually remotely true in
general, but is just made to be that way for afs and ceph.
See for example fs/cifs/cifsglob.h:
struct cifsInodeInfo {
struct {
/* These must be contiguous */
struct inode vfs_inode; /* the VFS's inode record */
struct netfs_i_context netfs_ctx; /* Netfslib context */
};
[...]
and realize that this is all entirely wrong, and the pointer arithmetic
that netfs_i_context() is doing is also very very wrong and wouldn't
give the right answer if netfs_ctx had different alignment rules from a
'struct inode', for example).
Anyway, that's just a long-winded way to say "the gcc-12 warning is
actually quite reasonable, and our code happens to work but is pretty
disgusting".
This is getting fixed properly, but for now I made the mistake of
thinking "the week right after the merge window tends to be calm for me
as people take a breather" and I did a sustem upgrade. And I got gcc-12
as a result, so to continue merging fixes from people and not have the
end result drown in warnings, I am fixing all these gcc-12 issues I hit.
Including with these kinds of temporary fixes.

[ Upstream commit 846bb97e131d7938847963cca00657c995b1fce1 ]
This commit changes the default Kconfig values of RANDOM_TRUST_CPU and
RANDOM_TRUST_BOOTLOADER to be Y by default. It does not change any
existing configs or change any kernel behavior. The reason for this is
several fold.
As background, I recently had an email thread with the kernel
maintainers of Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine,
SUSE, and Void as recipients. I noted that some distros trust RDRAND,
some trust EFI, and some trust both, and I asked why or why not. There
wasn't really much of a "debate" but rather an interesting discussion of
what the historical reasons have been for this, and it came up that some
distros just missed the introduction of the bootloader Kconfig knob,
while another didn't want to enable it until there was a boot time
switch to turn it off for more concerned users (which has since been
added). The result of the rather uneventful discussion is that every
major Linux distro enables these two options by default.
While I didn't have really too strong of an opinion going into this
thread -- and I mostly wanted to learn what the distros' thinking was
one way or another -- ultimately I think their choice was a decent
enough one for a default option (which can be disabled at boot time).
I'll try to summarize the pros and cons:
Pros:
- The RNG machinery gets initialized super quickly, and there's no
messing around with subsequent blocking behavior.
- The bootloader mechanism is used by kexec in order for the prior
kernel to initialize the RNG of the next kernel, which increases
the entropy available to early boot daemons of the next kernel.
- Previous objections related to backdoors centered around
Dual_EC_DRBG-like kleptographic systems, in which observing some
amount of the output stream enables an adversary holding the right key
to determine the entire output stream.
This used to be a partially justified concern, because RDRAND output
was mixed into the output stream in varying ways, some of which may
have lacked pre-image resistance (e.g. XOR or an LFSR).
But this is no longer the case. Now, all usage of RDRAND and
bootloader seeds go through a cryptographic hash function. This means
that the CPU would have to compute a hash pre-image, which is not
considered to be feasible (otherwise the hash function would be
terribly broken).
- More generally, if the CPU is backdoored, the RNG is probably not the
realistic vector of choice for an attacker.
- These CPU or bootloader seeds are far from being the only source of
entropy. Rather, there is generally a pretty huge amount of entropy,
not all of which is credited, especially on CPUs that support
instructions like RDRAND. In other words, assuming RDRAND outputs all
zeros, an attacker would *still* have to accurately model every single
other entropy source also in use.
- The RNG now reseeds itself quite rapidly during boot, starting at 2
seconds, then 4, then 8, then 16, and so forth, so that other sources
of entropy get used without much delay.
- Paranoid users can set random.trust_{cpu,bootloader}=no in the kernel
command line, and paranoid system builders can set the Kconfig options
to N, so there's no reduction or restriction of optionality.
- It's a practical default.
- All the distros have it set this way. Microsoft and Apple trust it
too. Bandwagon.
Cons:
- RDRAND *could* still be backdoored with something like a fixed key or
limited space serial number seed or another indexable scheme like
that. (However, it's hard to imagine threat models where the CPU is
backdoored like this, yet people are still okay making *any*
computations with it or connecting it to networks, etc.)
- RDRAND *could* be defective, rather than backdoored, and produce
garbage that is in one way or another insufficient for crypto.
- Suggesting a *reduction* in paranoia, as this commit effectively does,
may cause some to question my personal integrity as a "security
person".
- Bootloader seeds and RDRAND are generally very difficult if not all
together impossible to audit.
Keep in mind that this doesn't actually change any behavior. This
is just a change in the default Kconfig value. The distros already are
shipping kernels that set things this way.
Ard made an additional argument in [1]:
We're at the mercy of firmware and micro-architecture anyway, given
that we are also relying on it to ensure that every instruction in
the kernel's executable image has been faithfully copied to memory,
and that the CPU implements those instructions as documented. So I
don't think firmware or ISA bugs related to RNGs deserve special
treatment - if they are broken, we should quirk around them like we
usually do. So enabling these by default is a step in the right
direction IMHO.
In [2], Phil pointed out that having this disabled masked a bug that CI
otherwise would have caught:
A clean 5.15.45 boots cleanly, whereas a downstream kernel shows the
static key warning (but it does go on to boot). The significant
difference is that our defconfigs set CONFIG_RANDOM_TRUST_BOOTLOADER=y
defining that on top of multi_v7_defconfig demonstrates the issue on
a clean 5.15.45. Conversely, not setting that option in a
downstream kernel build avoids the warning

Currently if the APB or Debounce clocks aren't yet ready to be requested
the DW GPIO driver will correctly handle that by deferring the probe
procedure, but the error is still printed to the system log. It needlessly
pollutes the log since there was no real error but a request to postpone
the clock request procedure since the clocks subsystem hasn't been fully
initialized yet. Let's fix that by using the dev_err_probe method to print
the APB/clock request error status. It will correctly handle the deferred
probe situation and print the error if it actually happens.

[ Upstream commit 5b7419ae1d208cab1e2826d473d8dab045aa75c7 ]
In _rtw_init_xmit_priv, we use the res variable to store the error
return from the newly converted rtw_alloc_hwxmits function. Sadly, the
calling function interprets res using _SUCCESS and _FAIL still, meaning
we change the semantics of the variable, even in the success case.
This leads to the following on boot:
r8188eu 1-2:1.0: _rtw_init_xmit_priv failed
In the long term, we should reverse these semantics, but for now, this
fixes the driver. Also, inside rtw_alloc_hwxmits remove the if blocks,
as HWXMIT_ENTRY is always 4.

[ Upstream commit 880265c77ac415090090d1fe72a188fee71cb458 ]
If we're about to send the first layoutget for an empty layout, we want
to make sure that we drain out the existing pending layoutget calls
first. The reason is that these layouts may have been already implicitly
returned to the server by a recall to which the client gave a
NFS4ERR_NOMATCHING_LAYOUT response.
The problem is that wait_var_event_killable() could in principle see the
plh_outstanding count go back to '1' when the first process to wake up
starts sending a new layoutget. If it fails to get a layout, then this
loop can continue ad infinitum...

If the initial attempt at trunking detection using the krb5i auth flavor
fails with -EACCES, -NFS4ERR_CLID_INUSE, or -NFS4ERR_WRONGSEC, then the
NFS client tries again using auth_sys, cloning the rpc_clnt in the
process. If this second attempt at trunking detection succeeds, then
the resulting nfs_client->cl_rpcclient winds up having cl_max_connect=0
and subsequent attempts to add additional transport connections to the
rpc_clnt will fail with a message similar to the following being logged:

[ Upstream commit 245b993d8f6c4e25f19191edfbd8080b645e12b1 ]
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it has been broken for a decade.
Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.
There are two ways to fix it:
- Remove __init
- Remove EXPORT_SYMBOL
I chose the latter for this case because the only in-tree call-site,
arch/x86/kernel/cpu/mshyperv.c is never compiled as modular.
(CONFIG_HYPERVISOR_GUEST is boolean)

Procedure of configure tc flower filters erroneously allows to create
filters on TC0 where unfiltered packets are also directed by default.
Issue was caused by insufficient checks of hw_tc parameter specifying
the hardware traffic class to pass matching packets to.
Fix checking hw_tc parameter which blocks creation of filters on TC0.

[ Upstream commit fd5855e6b1358e816710afee68a1d2bc685176ca ]
After PF reset and ethtool -t there was call trace in dmesg
sometimes leading to panic. When there was some time, around 5
seconds, between reset and test there were no errors.
Problem was that pf reset calls i40e_vsi_close in prep_for_reset
and ethtool -t calls i40e_vsi_close in diag_test. If there was not
enough time between those commands the second i40e_vsi_close starts
before previous i40e_vsi_close was done which leads to crash.
Add check to diag_test if pf is in reset and don't start offline
tests if it is true.
Add netif_info("testing failed") into unhappy path of i40e_diag_test()

[ Upstream commit 645603844270b69175899268be68b871295764fe ]
After reinitialization of iavf, ice driver gets VIRTCHNL_OP_ADD_ETH_ADDR
message with incorrectly set type of MAC address. Hardware address should
have is_primary flag set as true. This way ice driver knows what it has
to set as a MAC address.
Check if the address is primary in iavf_add_filter function and set flag
accordingly.
To test set all-zero MAC on a VF. This triggers iavf re-initialization
and VIRTCHNL_OP_ADD_ETH_ADDR message gets sent to PF.
For example:
ip link set dev ens785 vf 0 mac 00:00:00:00:00:00
This triggers re-initialization of iavf. New MAC should be assigned.
Now check if MAC is non-zero:
ip link show dev ens785

[ Upstream commit 5e757deddd918edb8cb2fdb56eb79656ffc6dade ]
PolarFire SoC /does/ have a SiFive pdma, despite what I suggested as a
conflict resolution to Zong. Somehow the entry fell through the cracks
between versions of my dt patches, so re-add it with Zong's updated
compatible & dma-channels property.

[ Upstream commit c9b576d0c7bf55aeae1a736da7974fa202c4394d ]
Fix our pointer offset usage in error_state_read
when there is no i915_gpu_coredump but buf offset
is non-zero.
This fixes a kernel page fault can happen when
multiple tests are running concurrently in a loop
and one is producing engine resets and consuming
the i915 error_state dump while the other is
forcing full GT resets. (takes a while to trigger).

[ Upstream commit e93530ae0e5d8fcf2d908933d206e0c93bc3c09b ]
Currently, settings parameters of schedule mode, dwrr, shaper of tm
priority or qset of one tc are only be set when tc is enabled, they are
not restored to the default settings when tc is disabled. It confuses
users when they cat tm_priority or tm_qset files of debugfs. So this
patch fixes it.

Currently hns3 driver misuses the VF rss size to initialize the PF rss size
in hclge_tm_vport_tc_info_update. So this patch fix it by checking the
vport id before initialization.

[ Upstream commit 12a3670887725df364cc3e030cf3bede6f13b364 ]
Currently in driver initialization process, driver will set shapping
parameters of tm port to default speed read from firmware. However, the
speed of SFP module may not be default speed, so shapping parameters of
tm port may be incorrect.
To fix this problem, driver sets new shapping parameters for tm port
after getting exact speed of SFP module in this case.

[ Upstream commit 4b7a632ac4e7101ceefee8484d5c2ca505d347b3 ]
Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.
In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)
Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

[ Upstream commit 71a579f0d3777a704355e6f1572dfba92a9b58b2 ]
The offset was being incorrectly calculated for E822 - that led to
collisions in choosing TX timestamp register location when more than
one port was trying to use timestamping mechanism.
In E822 one quad is being logically split between ports, so quad 0 is
having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should
have separate memory location for tracking timestamps. Due to error for
example ports 1 and 2 had been assigned to quad 0 with same offset (0),
while port 1 should have offset 0 and 1 offset 16.
Fix it by correctly calculating quad offset.

[ Upstream commit be2af71496a54a7195ac62caba6fab49cfe5006c ]
Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail.
Not disabling them might lead to scenario, where PF driver leaves VF
queues enabled, when VF's VSI failed queue config.
In this scenario VF should not have RX/TX queues enabled. If PF failed
to set up VF's queues, VF will reset due to TX timeouts in VF driver.
Initialize iterator 'i' to -1, so if error happens prior to configuring
queues then error path code will not disable queue 0. Loop that
configures queues will is using same iterator, so error path code will
only disable queues that were configured.

[ Upstream commit efe41860008e57fb6b69855b4b93fdf34bc42798 ]
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled,
when it requests a reset. If PF driver assumes that VF is disabled,
while VF still has queues configured, VF may unmap DMA resources.
In such scenario device still can map packets to memory, which ends up
silently corrupting it.
Previously, VF driver could experience memory corruption, which lead to
crash:

'bgmac' is part of a managed resource allocated with bgmac_alloc(). It
should not be freed explicitly.
Remove the erroneous kfree() from the .remove() function.

[ Upstream commit f4b41f062c424209e3939a81e6da022e049a45f2 ]
skb_recv_datagram() has two parameters 'flags' and 'noblock' that are
merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)'
As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags'
into 'flags' and 'noblock' with finally obsolete bit operations like this:
skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc);
And this is not even done consistently with the 'flags' parameter.
This patch removes the obsolete and costly splitting into two parameters
and only performs bit operations when really needed on the caller side.
One missing conversion thankfully reported by kernel test robot. I missed
to enable kunit tests to build the mctp code.

Hello Greg,
as already answered to Sascha:

Hello Sasha,
this patch is some kind of improvement/simplification to reduce and
clean up the number of variables passed through skb_recv_datagram() call.
There is no functional change and therefore no need to backport this
patch IMO.
The 'Reported-by:' tag just came from the kernel test robot when posting
the original patch and getting direct feedback on some missing calling
sites.
Best regards,
Oliver

> merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)'
>
> As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags'
> into 'flags' and 'noblock' with finally obsolete bit operations like this:
>
> skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc);
>
> And this is not even done consistently with the 'flags' parameter.
>
> This patch removes the obsolete and costly splitting into two parameters
> and only performs bit operations when really needed on the caller side.
>
> One missing conversion thankfully reported by kernel test robot. I missed
> to enable kunit tests to build the mctp code.

It is needed by a follow-on patch that fixes a real issue.

Ah, ok! Wasn't aware of that follow-on patch.
Sorry for the noise ;-)

[ Upstream commit 219b51a6f040fa5367adadd7d58c4dda0896a01d ]
The skb_recv_datagram() in ax25_recvmsg() will hold lock_sock
and block until it receives a packet from the remote. If the client
doesn`t connect to server and calls read() directly, it will not
receive any packets forever. As a result, the deadlock will happen.
The fail log caused by deadlock is shown below:
[ 369.606973] INFO: task ax25_deadlock:157 blocked for more than 245 seconds.
[ 369.608919] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

[ Upstream commit 3eefdf9d1e406f3da47470b2854347009ffcb6fa ]
The branch range checks in ftrace_make_call() and ftrace_make_nop() are
incorrect, erroneously permitting a forwards branch of 128M and
erroneously rejecting a backwards branch of 128M.
This is because both functions calculate the offset backwards,
calculating the offset *from* the target *to* the branch, rather than
the other way around as the later comparisons expect.
If an out-of-range branch were erroeously permitted, this would later be
rejected by aarch64_insn_gen_branch_imm() as branch_imm_common() checks
the bounds correctly, resulting in warnings and the placement of a BRK
instruction. Note that this can only happen for a forwards branch of
exactly 128M, and so the caller would need to be exactly 128M bytes
below the relevant ftrace trampoline.
If an in-range branch were erroeously rejected, then:
* For modules when CONFIG_ARM64_MODULE_PLTS=y, this would result in the
use of a PLT entry, which is benign.
Note that this is the common case, as this is selected by
CONFIG_RANDOMIZE_BASE (and therefore RANDOMIZE_MODULE_REGION_FULL),
which distributions typically seelct. This is also selected by
CONFIG_ARM64_ERRATUM_843419.
* For modules when CONFIG_ARM64_MODULE_PLTS=n, this would result in
internal ftrace failures.
* For core kernel text, this would result in internal ftrace failues.
Note that for this to happen, the kernel text would need to be at
least 128M bytes in size, and typical configurations are smaller tha
this.
Fix this by calculating the offset *from* the branch *to* the target in
both functions.

[ Upstream commit a6253579977e4c6f7818eeb05bf2bc65678a7187 ]
Sometimes it is necessary to use a PLT entry to call an ftrace
trampoline. This is handled by ftrace_make_call() and ftrace_make_nop(),
with each having *almost* identical logic, but this is not handled by
ftrace_modify_call() since its introduction in commit:
3b23e4991fb66f6d ("arm64: implement ftrace with regs")
Due to this, if we ever were to call ftrace_modify_call() for a callsite
which requires a PLT entry for a trampoline, then either:
a) If the old addr requires a trampoline, ftrace_modify_call() will use
an out-of-range address to generate the 'old' branch instruction.
This will result in warnings from aarch64_insn_gen_branch_imm() and
ftrace_modify_code(), and no instructions will be modified. As
ftrace_modify_call() will return an error, this will result in
subsequent internal ftrace errors.
b) If the old addr does not require a trampoline, but the new addr does,
ftrace_modify_call() will use an out-of-range address to generate the
'new' branch instruction. This will result in warnings from
aarch64_insn_gen_branch_imm(), and ftrace_modify_code() will replace
the 'old' branch with a BRK. This will result in a kernel panic when
this BRK is later executed.
Practically speaking, case (a) is vastly more likely than case (b), and
typically this will result in internal ftrace errors that don't
necessarily affect the rest of the system. This can be demonstrated with
an out-of-tree test module which triggers ftrace_modify_call(), e.g.

We can solve this by consistently determining whether to use a PLT entry
for an address.
Note that since (the earlier) commit:
f1a54ae9af0da4d7 ("arm64: module/ftrace: intialize PLT at load time")
... we can consistently determine the PLT address that a given callsite
will use, and therefore ftrace_make_nop() does not need to skip
validation when a PLT is in use.
This patch factors the existing logic out of ftrace_make_call() and
ftrace_make_nop() into a common ftrace_find_callable_addr() helper
function, which is used by ftrace_make_call(), ftrace_make_nop(), and
ftrace_modify_call(). In ftrace_make_nop() the patching is consistently
validated by ftrace_modify_code() as we can always determine what the
old instruction should have been.

[ Upstream commit 4bca7e80b6455772b4bf3f536dcbc19aac424d6a ]
noop_backing_dev_info is used by superblocks of various
pseudofilesystems such as kdevtmpfs. After commit 10e14073107d
("writeback: Fix inode->i_io_list not be protected by inode->i_lock
error") this broke because __mark_inode_dirty() started to access more
fields from noop_backing_dev_info and this led to crashes inside
locked_inode_to_wb_and_lock_list() called from __mark_inode_dirty().
Fix the problem by initializing noop_backing_dev_info before the
filesystems get mounted.

[ Upstream commit dcea997beed694cbd8705100ca1a6eb0d886de69 ]
If a function lives in a section other than .text, but .text also exists
in the object, faddr2line may wrongly assume .text. This can result in
comically wrong output. For example:
$ scripts/faddr2line vmlinux.o enter_from_user_mode+0x1c
enter_from_user_mode+0x1c/0x30:
find_next_bit at /home/jpoimboe/git/linux/./include/linux/find.h:40
(inlined by) perf_clear_dirty_counters at /home/jpoimboe/git/linux/arch/x86/events/core.c:2504
Fix it by passing the section name to addr2line, unless the object file
is vmlinux, in which case the symbol table uses absolute addresses.

[ Upstream commit 7b6c7a877cc616bc7dc9cd39646fe454acbed48b ]
The file-wide OBJECT_FILES_NON_STANDARD annotation is used with
CONFIG_FRAME_POINTER to tell objtool to skip the entire file when frame
pointers are enabled. However that annotation is now deprecated because
it doesn't work with IBT, where objtool runs on vmlinux.o instead of
individual translation units.
Instead, use more fine-grained function-specific annotations:
- The 'save_mcount_regs' macro does funny things with the frame pointer.
Use STACK_FRAME_NON_STANDARD_FP to tell objtool to ignore the
functions using it.
- The return_to_handler() "function" isn't actually a callable function.
Instead of being called, it's returned to. The real return address
isn't on the stack, so unwinding is already doomed no matter which
unwinder is used. So just remove the STT_FUNC annotation, telling
objtool to ignore it. That also removes the implicit
ANNOTATE_NOENDBR, which now needs to be made explicit.
Fixes the following warning:
vmlinux.o: warning: objtool: __fentry__+0x16: return with modified stack frame

[ Upstream commit 04193d590b390ec7a0592630f46d559ec6564ba1 ]
The purpose of balance_push() is to act as a filter on task selection
in the case of CPU hotplug, specifically when taking the CPU out.
It does this by (ab)using the balance callback infrastructure, with
the express purpose of keeping all the unlikely/odd cases in a single
place.
In order to serve its purpose, the balance_push_callback needs to be
(exclusively) on the callback list at all times (noting that the
callback always places itself back on the list the moment it runs,
also noting that when the CPU goes down, regular balancing concerns
are moot, so ignoring them is fine).
And here-in lies the problem, __sched_setscheduler()'s use of
splice_balance_callbacks() takes the callbacks off the list across a
lock-break, making it possible for, an interleaving, __schedule() to
see an empty list and not get filtered.

[ Upstream commit 27071b5cbca59d8e8f8750c199a6cbf8c9799963 ]
Even though the DW I2C controller reference clock source is requested by
the method devm_clk_get() with non-optional clock requirement the way the
clock handler is used afterwards has a pure optional clock semantic
(though in some circumstances we can get a warning about the clock missing
printed in the system console). There is no point in reimplementing that
functionality seeing the kernel clock framework already supports the
optional interface from scratch. Thus let's convert the platform driver to
using it.
Note by providing this commit we get to fix two problems. The first one
was introduced in commit c62ebb3d5f0d ("i2c: designware: Add support for
an interface clock"). It causes not having the interface clock (pclk)
enabled/disabled in case if the reference clock isn't provided. The second
problem was first introduced in commit b33af11de236 ("i2c: designware: Do
not require clock when SSCN and FFCN are provided"). Since that
modification the deferred probe procedure has been unsupported in case if
the interface clock isn't ready.

The clsk are prepared, enabled, then disabled. So if an error occurs after
the disable step, they are still prepared.
Add an error handling path to unprepare the clks in such a case, as already

From: Alexander Usyskin <alexander.usyskin@intel.com>
commit 68553650bc9c57c7e530c84e5b2945e9dfe1a560 upstream.
Drop HBM responses also in the early shutdown phase where
the usual traffic is allowed.
Extend the rule that drop HBM responses received during the shutdown
phase by also in MEI_DEV_POWERING_DOWN state.
This resolves the stall if the driver is stopping in the middle
of the link initialization or link reset.
Drop the capabilities response on early shutdown.

commit 242439f7e279d86b3f73b5de724bc67b2f8aeb07 upstream.
The expression for setting the size of the allocated bulk TX buffer
(`devpriv->usb_tx_buf`) is calling `usb_endpoint_maxp(devpriv->ep_rx)`,
which is using the wrong endpoint (should be `devpriv->ep_tx`). Fix it.

commit abfed87e2a12bd246047d78c01d81eb9529f1d06 upstream.
This is used by code that doesn't need CONFIG_CRYPTO, so move this into
lib/ with a Kconfig option so that it can be selected by whatever needs
it.
This fixes a linker error Zheng pointed out when
CRYPTO_MANAGER_DISABLE_TESTS!=y and CRYPTO=m:
lib/crypto/curve25519-selftest.o: In function `curve25519_selftest':

commit c50f11c6196f45c92ca48b16a5071615d4ae0572 upstream.
Invalidating the buffer memory in arch_sync_dma_for_device() for
FROM_DEVICE transfers
When using the streaming DMA API to map a buffer prior to inbound
non-coherent DMA (i.e. DMA_FROM_DEVICE), we invalidate any dirty CPU
cachelines so that they will not be written back during the transfer and
corrupt the buffer contents written by the DMA. This, however, poses two
potential problems:
(1) If the DMA transfer does not write to every byte in the buffer,
then the unwritten bytes will contain stale data once the transfer
has completed.
(2) If the buffer has a virtual alias in userspace, then stale data
may be visible via this alias during the period between performing
the cache invalidation and the DMA writes landing in memory.
Address both of these issues by cleaning (aka writing-back) the dirty
lines in arch_sync_dma_for_device(DMA_FROM_DEVICE) instead of discarding
them using invalidation.

From: Wesley Cheng <quic_wcheng@quicinc.com>
commit 9c1e916960c1192e746bf615e4dae25423473a64 upstream.
The current logic to assign the max packet limit for IN endpoints attempts
to take the default HW value and apply the optimal endpoint settings based
on it. However, if the default value reports a TxFIFO size large enough
for only one max packet, it will divide the value and assign a smaller ep
max packet limit.
For example, if the default TxFIFO size fits 1024B, current logic will
assign 1024/3 = 341B to ep max packet size. If function drivers attempt to
request for an endpoint with a wMaxPacketSize of 1024B (SS BULK max packet
size) then it will fail, as the gadget is unable to find an endpoint which
can fit the requested size.
Functionally, if the TxFIFO has enough space to fit one max packet, it will
be sufficient, at least when initializing the endpoints.

commit 7ddda2614d62ef7fdef7fd85f5151cdf665b22d8 upstream.
Commit 582ab24e096f ("usb: dwc3: pci: Set "linux,phy_charger_detect"
property on some Bay Trail boards") added a new swnode similar to the
existing ones for boards where the PHY handles charger detection.
Unfortunately, the "linux,sysdev_is_parent" property got lost in the
merge conflict resolution of commit ca9400ef7f67 ("Merge 5.17-rc6 into
usb-next"). Now dwc3_pci_intel_phy_charger_detect_properties is the
only swnode in dwc3-pci that is missing "linux,sysdev_is_parent".
It does not seem to cause any obvious functional issues, but it's
certainly unintended so restore the line to make the properties
consistent again.

From: Marian Postevca <posteuca@mutex.one>
commit b337af3a4d6147000b7ca6b3438bf5c820849b37 upstream.
In systemd systems setting a fixed MAC address through
the "dev_addr" module argument fails systematically.
When checking the MAC address after the interface is created
it always has the same but different MAC address to the one
supplied as argument.
This is partially caused by systemd which by default will
set an internally generated permanent MAC address for interfaces
that are marked as having a randomly generated address.
Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in
setting MAC address in setup phase") didn't take into account
the fact that the interface must be marked as having a set
MAC address when it's set as module argument.
Fixed by marking the interface with NET_ADDR_SET when
the "dev_addr" module argument is supplied.

commit fb1f16d74e263baa4ad11e31e28b68f144aa55ed upstream.
If a task read/write data in blocking mode, it will wait the completion
in ffs_epfile_io(), if function unbind occurs, ffs_func_unbind() will
kfree ffs ep, once the task wake up, it still dereference the ffs ep to
obtain the request status.
Fix it by moving the request status to io_data which is stack-safe.

commit be03b0651ffd8bab69dfd574c6818b446c0753ce upstream.
Not all LSR register flags are preserved across reads. Therefore, LSR
readers must store the non-preserved bits into lsr_save_flags.
This fix was initially mixed into feature commit f6f586102add ("serial:
8250: Handle UART without interrupt on TEMT using em485"). However,
that feature change had a flaw and it was reverted to make room for
simpler approach providing the same feature. The embedded fix got
reverted with the feature change.
Re-add the lsr_save_flags fix and properly mark it's a fix.

commit 928ea98252ad75118950941683893cf904541da9 upstream.
In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to
fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in
fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io
triggers KASAN use-after-free. To avoid the use-after-free, keep the
reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to
fsl_destroy_mc_io().
This patch needs rework to apply to kernels older than v5.15.

commit f34fdcd4a0e7a0b92340ad7e48e7bcff9393fab5 upstream.
bio_alloc_bioset() takes a block device, number of vectors, the
OP flags, the GFP mask and the bio set. However when the prototype
was changed, the callisite in ppl_do_flush() had the OP flags and
the GFP flags reversed. This introduced some sparse error:
drivers/md/raid5-ppl.c:632:57: warning: incorrect type in argument 3
(different base types)
drivers/md/raid5-ppl.c:632:57: expected unsigned int opf

gfp_mask
drivers/md/raid5-ppl.c:633:61: got unsigned long long
The sparse error introduction may not have been reported correctly by
0day due to other work that was cleaning up other sparse errors in this
area.

commit 10eb3a0d517fcc83eeea4242c149461205675eb4 upstream.
After commit 82f6cdcc3676c ("dm: switch dm_io booleans over to proper
flags") dm_start_io_acct stopped atomically checking and setting
was_accounted, which turned into the DM_IO_ACCOUNTED flag. This opened
the possibility for a race where IO accounting is started twice for
duplicate bios. To remove the race, check the flag while holding the
io->lock.

From: Mikulas Patocka <mpatocka@redhat.com>
commit 85e123c27d5cbc22cfdc01de1e2ca1d9003a02d0 upstream.
The code in dm-log rounds up bitset_size to 32 bits. It then uses
find_next_zero_bit_le on the allocated region. find_next_zero_bit_le
accesses the bitmap using unsigned long pointers. So, on 64-bit
architectures, it may access 4 bytes beyond the allocated size.
Fix this bug by rounding up bitset_size to BITS_PER_LONG.
This bug was found by running the lvm2 testsuite with kasan.

commit 4fd17f2ac0aa4e48823ac2ede5b050fb70300bf4 upstream.
[Why]
For OLED eDP the Display Manager uses max_cll value as a limit
for brightness control.
max_cll defines the content light luminance for individual pixel.
Whereas max_fall defines frame-average level luminance.
The user may not observe the difference in brightness in between
max_fall and max_cll.
That negatively impacts the user experience.
[How]
Use max_fall value instead of max_cll as a limit for brightness control.

commit 168f912893407a5acb798a4a58613b5f1f98c717 upstream.
When calling setattr_prepare() to determine the validity of the
attributes the ia_{g,u}id fields contain the value that will be written
to inode->i_{g,u}id. This is exactly the same for idmapped and
non-idmapped mounts and allows callers to pass in the values they want
to see written to inode->i_{g,u}id.
When group ownership is changed a caller whose fsuid owns the inode can
change the group of the inode to any group they are a member of. When
searching through the caller's groups we need to use the gid mapped
according to the idmapped mount otherwise we will fail to change
ownership for unprivileged users.
Consider a caller running with fsuid and fsgid 1000 using an idmapped
mount that maps id 65534 to 1000 and 65535 to 1001. Consequently, a file
owned by 65534:65535 in the filesystem will be owned by 1000:1001 in the
idmapped mount.
The caller now requests the gid of the file to be changed to 1000 going
through the idmapped mount. In the vfs we will immediately map the
requested gid to the value that will need to be written to inode->i_gid
and place it in attr->ia_gid. Since this idmapped mount maps 65534 to
1000 we place 65534 in attr->ia_gid.
When we check whether the caller is allowed to change group ownership we
first validate that their fsuid matches the inode's uid. The
inode->i_uid is 65534 which is mapped to uid 1000 in the idmapped mount.
Since the caller's fsuid is 1000 we pass the check.
We now check whether the caller is allowed to change inode->i_gid to the
requested gid by calling in_group_p(). This will compare the passed in
gid to the caller's fsgid and search the caller's additional groups.
Since we're dealing with an idmapped mount we need to pass in the gid
mapped according to the idmapped mount. This is akin to checking whether
a caller is privileged over the future group the inode is owned by. And
that needs to take the idmapped mount into account. Note, all helpers
are nops without idmapped mounts.
New regression test sent to xfstests.

Checksum errors in superblock! Retrying...
Reason is ext4_orphan_cleanup will reset ‘s_last_orphan’ but not update
super block checksum.
To solve above issue, defer update super block checksum after
ext4_orphan_cleanup.

we can easily reproduce this problem with the following commands:
`fallocate -l100M disk`
`mkfs.ext4 -b 1024 -g 256 disk`
`mount disk /mnt`
`fsstress -d /mnt -l 0 -n 1000 -p 1`
The size must be smaller than or equal to EXT4_BLOCKS_PER_GROUP.
Therefore, "start + size <= ac->ac_o_ex.fe_logical" may occur
when the size is truncated. So start should be the start position of
the group where ac_o_ex.fe_logical is located after alignment.
In addition, when the value of fe_logical or EXT4_BLOCKS_PER_GROUP
is very large, the value calculated by start_off is more accurate.

commit b55c3cd102a6f48b90e61c44f7f3dda8c290c694 upstream.
We capture a NULL pointer issue when resizing a corrupt ext4 image which
is freshly clear resize_inode feature (not run e2fsck). It could be
simply reproduced by following steps. The problem is because of the
resize_inode feature was cleared, and it will convert the filesystem to
meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was
not reduced to zero, so could we mistakenly call reserve_backup_gdb()
and passing an uninitialized resize_inode to it when adding new group

commit d52d165d67c5aa26c8c89909003c94a66492d23d upstream.
On each vcpu load, we set the KVM_ARM64_HOST_SVE_ENABLED
flag if SVE is enabled for EL0 on the host. This is used to restore
the correct state on vpcu put.
However, it appears that nothing ever clears this flag. Once
set, it will stick until the vcpu is destroyed, which has the
potential to spuriously enable SVE for userspace.
We probably never saw the issue because no VMM uses SVE, but
that's still pretty bad. Unconditionally clearing the flag
on vcpu load addresses the issue.

commit 2cdea19a34c2340b3aa69508804efe4e3750fcec upstream.
Since 5bfa685e62e9 ("KVM: arm64: vgic: Read HW interrupt pending state
from the HW"), we're able to source the pending bit for an interrupt
that is stored either on the physical distributor or on a device.
However, this state is only available when the vcpu is loaded,
and is not intended to be accessed from userspace. Unfortunately,
the GICv2 emulation doesn't provide specific userspace accessors,
and we fallback with the ones that are intended for the guest,
with fatal consequences.
Add a new vgic_uaccess_read_pending() accessor for userspace
to use, build on top of the existing vgic_mmio_read_pending().

commit 7e415282b41bf0d15c6e0fe268f822d9b083f2f7 upstream.
GCC 12 enhanced -Waddress when comparing array address to null [0],
which warns:
drivers/virtio/virtio_pci_common.c: In function ‘vp_del_vqs’:
drivers/virtio/virtio_pci_common.c:257:29: warning: the comparison will always evaluate as ‘true’ for the pointer operand in ‘vp_dev->msix_affinity_masks + (sizetype)((long unsigned int)i * 256)’ must not be NULL [-Waddress]
257 | if (vp_dev->msix_affinity_masks[i])
| ^~~~~~
In fact, the verification is comparing the result of a pointer
arithmetic, the address "msix_affinity_masks + i", which will always
evaluate to true.
Under the hood, free_cpumask_var() calls kfree(), which is safe to pass
NULL, not requiring non-null verification. So remove the verification
to make compiler happy (happy compiler, happy life).

From: David Howells <dhowells@redhat.com>
commit 874c8ca1e60b2c564a48f7e7acc40d328d5c8733 upstream.
While randstruct was satisfied with using an open-coded "void *" offset
cast for the netfs_i_context <-> inode casting, __builtin_object_size() as
used by FORTIFY_SOURCE was not as easily fooled. This was causing the
following complaint[1] from gcc v12:
In file included from include/linux/string.h:253,
from include/linux/ceph/ceph_debug.h:7,
from fs/ceph/inode.c:2:
In function 'fortify_memset_chk',
inlined from 'netfs_i_context_init' at include/linux/netfs.h:326:2,
inlined from 'ceph_alloc_inode' at fs/ceph/inode.c:463:2:
include/linux/fortify-string.h:242:25: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
242 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix this by embedding a struct inode into struct netfs_i_context (which
should perhaps be renamed to struct netfs_inode). The struct inode
vfs_inode fields are then removed from the 9p, afs, ceph and cifs inode
structs and vfs_inode is then simply changed to "netfs.inode" in those
filesystems.
Further, rename netfs_i_context to netfs_inode, get rid of the
netfs_inode() function that converted a netfs_i_context pointer to an
inode pointer (that can now be done with &ctx->inode) and rename the
netfs_i_context() function to netfs_inode() (which is now a wrapper
around container_of()).
Most of the changes were done with:
perl -p -i -e 's/vfs_inode/netfs.inode/'g \
`git grep -l 'vfs_inode' -- fs/{9p,afs,ceph,cifs}/*.[ch]`
Kees suggested doing it with a pair structure[2] and a special
declarator to insert that into the network filesystem's inode
wrapper[3], but I think it's cleaner to embed it - and then it doesn't
matter if struct randomisation reorders things.
Dave Chinner suggested using a filesystem-specific VFS_I() function in
each filesystem to convert that filesystem's own inode wrapper struct
into the VFS inode struct[4].
Version #2:
- Fix a couple of missed name changes due to a disabled cifs option.
- Rename nfs_i_context to nfs_inode
- Use "netfs" instead of "nic" as the member name in per-fs inode wrapper
structs.
[ This also undoes commit 507160f46c55 ("netfs: gcc-12: temporarily
disable '-Wattribute-warning' for now") that is no longer needed ]

commit fd58f7df2415ef747782e01f94880fefad1247cf upstream.
The kvmalloc_array() function is safer because it has a check for
integer overflows. These sizes come from the user and I was not
able to see any bounds checking so an integer overflow seems like a
realistic concern.

From: Masahiro Yamada <masahiroy@kernel.org>
commit 7ad4bd887d27c6b6ffbef216f19c19f8fe2b8f52 upstream.
You cannot include <generated/compile.h> here because it is generated
in init/Makefile but there is no guarantee that it happens before
arch/powerpc/mm/nohash/kaslr_booke.c is compiled for parallel builds.
The places where you can reliably include <generated/compile.h> are:
- init/ (because init/Makefile can specify the dependency)
- arch/*/boot/ (because it is compiled after vmlinux)
Commit f231e4333312 ("hexagon: get rid of #include <generated/compile.h>")
fixed the last breakage at that time, but powerpc re-added this.
<generated/compile.h> was unneeded because 'build_str' is almost the
same as 'linux_banner' defined in init/version.c
Let's copy the solution from MIPS.

commit 29dec90a0f1d961b93f34f910e9319d8cb23edbd upstream.
The use of bioset_init_from_src mean that the pre-allocated pools weren't
used for anything except parameter passing, and the integrity pool
creation got completely lost for the actual live mapped_device. Fix that
by assigning the actual preallocated dm_md_mempools to the mapped_device
and using that for I/O instead of creating new mempools.
