[PATCH AUTOSEL 6.9 01/20] ALSA: hda: cs35l56: Fix lifecycle of codec pointer

[Sasha Levin]

From: Simon Trimmer <simont@opensource.cirrus.com>

[ Upstream commit d339131bf02d4ed918415574082caf5e8af6e664 ]

The codec should be cleared when the amp driver is unbound and when
resuming it should be tested to prevent loading firmware into the device
and ALSA in a partially configured system state.

[PATCH AUTOSEL 6.9 02/20] wifi: cfg80211: wext: add extra SIOCSIWSCAN data check

[Sasha Levin]

From: Dmitry Antipov <dmantipov@yandex.ru>

[ Upstream commit 6ef09cdc5ba0f93826c09d810c141a8d103a80fc ]

In 'cfg80211_wext_siwscan()', add extra check whether number of
channels passed via 'ioctl(sock, SIOCSIWSCAN, ...)' doesn't exceed
IW_MAX_FREQUENCIES and reject invalid request with -EINVAL otherwise.

[PATCH AUTOSEL 6.9 08/20] KVM: PPC: Book3S HV: Prevent UAF in kvm_spapr_tce_attach_iommu_group()

[Sasha Levin]

From: Michael Ellerman <mpe@ellerman.id.au>

[ Upstream commit a986fa57fd81a1430e00b3c6cf8a325d6f894a63 ]

Al reported a possible use-after-free (UAF) in kvm_spapr_tce_attach_iommu_group().

It looks up `stt` from tablefd, but then continues to use it after doing
fdput() on the returned fd. After the fdput() the tablefd is free to be
closed by another thread. The close calls kvm_spapr_tce_release() and
then release_spapr_tce_table() (via call_rcu()) which frees `stt`.

Although there are calls to rcu_read_lock() in
kvm_spapr_tce_attach_iommu_group() they are not sufficient to prevent
the UAF, because `stt` is used outside the locked regions.

With an artifcial delay after the fdput() and a userspace program which
triggers the race, KASAN detects the UAF:

Fix it by delaying the fdput() until `stt` is no longer in use, which
is effectively the entire function. To keep the patch minimal add a call
to fdput() at each of the existing return paths. Future work can convert
the function to goto or __cleanup style cleanup.

With the fix in place the test case no longer triggers the UAF.

[PATCH AUTOSEL 6.9 09/20] drm/vmwgfx: Fix missing HYPERVISOR_GUEST dependency

[Sasha Levin]

From: Alexey Makhalov <alexey.makhalov@broadcom.com>

VMWARE_HYPERCALL alternative will not work as intended without VMware guest code
initialization.

  [ bp: note that this doesn't reproduce with newer gccs so it must be
    something gcc-9-specific. ]

[PATCH AUTOSEL 6.9 12/20] cpumask: limit FORCE_NR_CPUS to just the UP case

[Sasha Levin]

From: Linus Torvalds <torvalds@linux-foundation.org>

[ Upstream commit 5d272dd1b3430bb31fa30042490fa081512424e4 ]

Hardcoding the number of CPUs at compile time does improve code
generation, but if you get it wrong the result will be confusion.

We already limited this earlier to only "experts" (see commit
fe5759d5bfda "cpumask: limit visibility of FORCE_NR_CPUS"), but with
distro kernel configs often having EXPERT enabled, that turns out to not
be much of a limit.

To quote the philosophers at Disney: "Everyone can be an expert. And
when everyone's an expert, no one will be".

There's a runtime warning if you then set nr_cpus to anything but the
forced number, but apparently that can be ignored too [1] and by then
it's pretty much too late anyway.

If we had some real way to limit this to "embedded only", maybe it would
be worth it, but let's see if anybody even notices that the option is
gone.  We need to simplify kernel configuration anyway.

[PATCH AUTOSEL 6.9 13/20] selftests: openvswitch: Set value to nla flags.

From: Adrian Moreno <amorenoz@redhat.com>

[PATCH AUTOSEL 6.9 18/20] ALSA: hda: cs35l56: Select SERIAL_MULTI_INSTANTIATE

[Sasha Levin]

From: Simon Trimmer <simont@opensource.cirrus.com>

[ Upstream commit 9b1effff19cdf2230d3ecb07ff4038a0da32e9cc ]

The ACPI IDs used in the CS35L56 HDA drivers are all handled by the
serial multi-instantiate driver which starts multiple Linux device
instances from a single ACPI Device() node.

As serial multi-instantiate is not an optional part of the system add it
as a dependency in Kconfig so that it is not overlooked.

[PATCH AUTOSEL 6.9 19/20] mips: fix compat_sys_lseek syscall

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 0d5679a0aae2d8cda72169452c32e5cb88a7ab33 ]

This is almost compatible, but passing a negative offset should result
in a EINVAL error, but on mips o32 compat mode would seek to a large
32-bit byte offset.

Use compat_sys_lseek() to correctly sign-extend the argument.

[PATCH AUTOSEL 6.9 20/20] closures: Change BUG_ON() to WARN_ON()

[Sasha Levin]

From: Kent Overstreet <kent.overstreet@linux.dev>

[ Upstream commit 339b84ab6b1d66900c27bd999271cb2ae40ce812 ]

If a BUG_ON() can be hit in the wild, it shouldn't be a BUG_ON()

For reference, this has popped up once in the CI, and we'll need more
info to debug it:
