commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.
Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
and the minimum is 1 since a multiple BSSID set with just one BSSID
doesn't make sense (the # of BSSIDs is limited by 2^n).
Limit this in the parsing in both cfg80211 and mac80211, rejecting
any elements with an invalid value.
This fixes potentially bad shifts in the processing of these inside
the cfg80211_gen_new_bssid() function later.
I found this during the investigation of CVE-2022-41674 fixed by the
previous patch.
Fixes: 0b8fb8235be8 ("cfg80211: Parsing of Multiple BSSID information in scanning")
Fixes: 78ac51f81532 ("mac80211: support multi-bssid")

commit 9ee0507e896b45af6d65408c77815800bce30008 upstream.
In order to avoid reading and dirtying two cache lines on every IRQ,
move the work_struct to the bottom of the fast_pool struct. add_
interrupt_randomness() always touches .pool and .count, which are
currently split, because .mix pushes everything down. Instead, move .mix
to the bottom, so that .pool and .count are always in the first cache
line, since .mix is only accessed when the pool is full.
Fixes: 58340f8e952b ("random: defer fast pool mixing to worker")

[ Upstream commit 02181e68275d28cab3c3f755852770367f1bc229 ]
Driver moxart-mmc.c has .compatible = "moxa,moxart-mmc".
But moxart .dts/.dtsi and the documentation file moxa,moxart-dma.txt
contain compatible = "moxa,moxart-sdhci".
Change moxart .dts/.dtsi files and moxa,moxart-dma.txt to match the driver.
Replace 'sdhci' with 'mmc' in names too, since SDHCI is a different
controller from FTSDC010.

When updating beacon elements in a non-transmitted BSS,
also update the hidden sub-entries to the same beacon
elements, so that a future update through other paths
won't trigger a WARN_ON().
The warning is triggered because the beacon elements in
the hidden BSSes that are children of the BSS should
always be the same as in the parent.

Currently, when removing the SCMI PM driver not all the resources
registered with genpd subsystem are properly de-registered.
As a side effect of this after a driver unload/load cycle you get a
splat with a few warnings like this:
| debugfs: Directory 'BIG_CPU0' with parent 'pm_genpd' already present!
| debugfs: Directory 'BIG_CPU1' with parent 'pm_genpd' already present!
| debugfs: Directory 'LITTLE_CPU0' with parent 'pm_genpd' already present!

| debugfs: Directory 'DBGSYS' with parent 'pm_genpd' already present!
| debugfs: Directory 'GPUTOP' with parent 'pm_genpd' already present!
Add a proper scmi_pm_domain_remove callback to the driver in order to
take care of all the needed cleanups not handled by devres framework.

From: Letu Ren <[email protected]>
[ Upstream commit fbfe96869b782364caebae0445763969ddb6ea67 ]
In __qedf_probe(), if qedf->cdev is NULL which means
qed_ops->common->probe() failed, then the program will goto label err1, and
scsi_host_put() will free lport->host pointer. Because the memory qedf
points to is allocated by libfc_host_alloc(), it will be freed by
scsi_host_put(). However, the if statement below label err0 only checks
whether qedf is NULL but doesn't check whether the memory has been freed.
So a UAF bug can occur.
There are two ways to reach the statements below err0. The first one is
described as before, "qedf" should be set to NULL. The second one is goto
"err0" directly. In the latter scenario qedf hasn't been changed and it has
the initial value NULL. As a result the if statement is not reachable in
any situation.
The KASAN logs are as follows:

commit 2e488f13755ffbb60f307e991b27024716a33b29 upstream.
In alloc_inode, inode_init_always() could return -ENOMEM if
security_inode_alloc() fails, which causes inode->i_private
uninitialized. Then nilfs_is_metadata_file_inode() returns
true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(),
which frees the uninitialized inode->i_private
and leads to crashes(e.g., UAF/GPF).
Fix this by moving security_inode_alloc just prior to
this_cpu_inc(nr_inodes)

2.35.1
From: Brian Norris <[email protected]>
commit e9233917a7e53980664efbc565888163c0a33c3f upstream.
This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.
Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.
Note that SDIO learned a similar retry loop in commit 0797e5f1453b
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:
rocr & ocr & R4_18V_PRESENT
(i.e., it doesn't have the same bug.)
This addresses a number of crash reports seen on ChromeOS that look
like the following:
... // lots of repeated: ...

commit 723ac751208f6d6540191689cfbf6c77135a7a1b upstream.
If creation or finalization of a checkpoint fails due to anomalies in the
checkpoint metadata on disk, a kernel warning is generated.
This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted
with panic_on_warn, does not panic. A nilfs_error is appropriate here to
handle the abnormal filesystem condition.
This also replaces the detected error codes with an I/O error so that
neither of the internal error codes is returned to callers.

commit 6022f210461fef67e6e676fd8544ca02d1bcfa7a upstream.
The passthrough structure is declared off of the stack, so it needs to be
set to zero before copied back to userspace to prevent any unintentional
data leakage. Switch things to be statically allocated which will fill the
unused fields with 0 automatically.

commit d0d51a97063db4704a5ef6bc978dddab1636a306 upstream.
If nilfs_attach_log_writer() failed to create a log writer thread, it
frees a data structure of the log writer without any cleanup. After
commit e912a5b66837 ("nilfs2: use root object to get ifile"), this causes
a leak of struct nilfs_root, which started to leak an ifile metadata inode
and a kobject on that struct.
In addition, if the kernel is booted with panic_on_warn, the above
ifile metadata inode leak will cause the following panic when the
nilfs2 kernel module is removed:

commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.
There are multiple refcounting bugs related to multi-BSSID:
- In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
the bss pointer is overwritten before checking for the
transmitted BSS, which is clearly wrong. Fix this by using
the bss_from_pub() macro.
- In cfg80211_bss_update() we copy the transmitted_bss pointer
from tmp into new, but then if we release new, we'll unref
it erroneously. We already set the pointer and ref it, but
need to NULL it since it was copied from the tmp data.
- In cfg80211_inform_single_bss_data(), if adding to the non-
transmitted list fails, we unlink the BSS and yet still we
return it, but this results in returning an entry without
a reference. We shouldn't return it anyway if it was broken
enough to not get added there.
This fixes CVE-2022-42720.

commit bab715bdaa9ebf28d99a6d1efb2704a30125e96d upstream.
It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which
is inconsistent with other model line names.
Correct the capitalisation of Macmini in the quirk for skipping loading
platform certs on T2 Macs.
Currently users get:

commit 21a87d88c2253350e115029f14fe2a10a7e6c856 upstream.
If the i_mode field in inode of metadata files is corrupted on disk, it
can cause the initialization of bmap structure, which should have been
called from nilfs_read_inode_common(), not to be called. This causes a
lockdep warning followed by a NULL pointer dereference at
nilfs_bmap_lookup_at_level().
This patch fixes these issues by adding a missing sanitiy check for the
i_mode field of metadata file's inode.

commit cd4f24ae9404fd31fc461066e57889be3b68641b upstream.
Prior to 5.6, when /dev/random was opened with O_NONBLOCK, it would
return -EAGAIN if there was no entropy. When the pools were unified in
5.6, this was lost. The post 5.6 behavior of blocking until the pool is
initialized, and ignoring O_NONBLOCK in the process, went unnoticed,
with no reports about the regression received for two and a half years.
However, eventually this indeed did break somebody's userspace.
So we restore the old behavior, by returning -EAGAIN if the pool is not
initialized. Unlike the old /dev/random, this can only occur during
early boot, after which it never blocks again.
In order to make this O_NONBLOCK behavior consistent with other
expectations, also respect users reading with preadv2(RWF_NOWAIT) and
similar.

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream.
Suspending and resuming the system can sometimes cause the out
URB to get hung after a reset_resume. This causes LED setting
and force feedback to break on resume. To avoid this, just drop
the reset_resume callback so the USB core rebinds xpad to the
wireless pads on resume if a reset happened.
A nice side effect of this change is the LED ring on wireless
controllers is now set correctly on system resume.

Then, we check namelen according to addr_type.

When iterating the elements here, ensure the length byte is
present before checking it to see if the entire element will
fit into the buffer.
Longer term, we should rewrite this code using the type-safe

commit 766279a8f85df32345dbda03b102ca1ee3d5ddea upstream.
The use of strncpy() is considered deprecated for NUL-terminated
strings[1]. Replace strncpy() with strscpy_pad(), to keep existing
pad-behavior of strncpy, similarly to commit 08de420a8014 ("rpmsg:
glink: Replace strncpy() with strscpy_pad()"). This fixes W=1 warning:
In function ‘qcom_glink_rx_close’,
inlined from ‘qcom_glink_work’ at ../drivers/rpmsg/qcom_glink_native.c:1638:4:

commit 748bc4dd9e663f23448d8ad7e58c011a67ea1eca upstream.
Previously, the fast pool was dumped into the main pool periodically in
the fast pool's hard IRQ handler. This worked fine and there weren't
problems with it, until RT came around. Since RT converts spinlocks into
sleeping locks, problems cropped up. Rather than switching to raw
spinlocks, the RT developers preferred we make the transformation from
originally doing:
do_some_stuff()
spin_lock()
do_some_other_stuff()
spin_unlock()
to doing:
do_some_stuff()
queue_work_on(some_other_stuff_worker)
This is an ordinary pattern done all over the kernel. However, Sherry
noticed a 10% performance regression in qperf TCP over a 40gbps
InfiniBand card. Quoting her message:
> MT27500 Family [ConnectX-3] cards:
> Infiniband device 'mlx4_0' port 1 status:
> default gid: fe80:0000:0000:0000:0010:e000:0178:9eb1

> sm lid: 0x1
> state: 4: ACTIVE
> phys state: 5: LinkUp
> rate: 40 Gb/sec (4X QDR)
> link_layer: InfiniBand
>
> Cards are configured with IP addresses on private subnet for IPoIB
> performance testing.
> Regression identified in this bug is in TCP latency in this stack as reported
> by qperf tcp_lat metric:
>
> We have one system listen as a qperf server:
> [root@yourQperfServer ~]# qperf
>
> Have the other system connect to qperf server as a client (in this
> case, it’s X7 server with Mellanox card):
> [root@yourQperfClient ~]# numactl -m0 -N0 qperf 20.20.20.101 -v -uu -ub --time 60 --wait_server 20 -oo msg_size:4K:1024K:*2 tcp_lat
Rather than incur the scheduling latency from queue_work_on, we can
instead switch to running on the next timer tick, on the same core. This
also batches things a bit more -- once per jiffy -- which is okay now
that mix_interrupt_randomness() can credit multiple bits at once.

commit 56e696c0f0c71b77fff921fc94b58a02f0445b2c upstream.
Hans reported that his Sony VAIO VPX11S1E showed the broken sound
behavior at the start of the stream for a couple of seconds, and it
turned out that the position_fix=1 option fixes the issue. It implies
that the position reporting is inaccurate, and very likely hitting on
all Poulsbo devices.
The patch applies the workaround for Poulsbo generically to switch to
LPIB mode instead of the default position buffer.

[ Upstream commit bd71558d585ac61cfd799db7f25e78dca404dd7a ]
Since binutils 2.39, ld will print a warning if any stack section is
executable, which is the default for stack sections on files without a
.note.GNU-stack section.
This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"),
but remained broken for UML, resulting in several warnings:
/usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms1 has a LOAD segment with RWX permissions
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms1.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms2 has a LOAD segment with RWX permissions
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms2.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions
Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings
about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments
to dodge the remaining warnings about LOAD segments with RWX permissions
in the kallsyms objects. (Note that this flag is apparently not
available on lld, so hide it behind a test for BFD, which is what the
x86 patch does.)
