ASoC: Fixes for v6.17

A few final driver specific fixes for v6.17, none super urgent so
waiting for v6.18 and backporting is probably fine for htem.

Although the MCU emulates the same behavior, be prepared for any quirks

Eric Biggers 4ef77dd584 libbpf: Replace AF_ALG with open coded SHA-256
Reimplement libbpf_sha256() using some basic SHA-256 C code.  This
eliminates the newly-added dependency on AF_ALG, which is a problematic
UAPI that is not supported by all kernels.

Make libbpf_sha256() return void, since it can no longer fail.  This
simplifies some callers.  Also drop the unnecessary 'sha_out_sz'
parameter.  Finally, also fix the typo in "compute_sha_udpate_offsets".

pengdonglin c7bc7e9070 ACPI: APEI: Remove redundant rcu_read_lock/unlock() under spinlock
Since commit a8bb74acd8 ("rcu: Consolidate RCU-sched update-side
function definitions") there is no difference between rcu_read_lock(),
rcu_read_lock_bh() and rcu_read_lock_sched() in terms of RCU read
section and the relevant grace period. That means that spin_lock(),
which implies rcu_read_lock_sched(), also implies rcu_read_lock().

There is no need no explicitly start a RCU read section if one has
already been started implicitly by spin_lock().

Simplify the code and remove the inner rcu_read_lock() invocation.

Rafael J. Wysocki 399dbcadc0 ACPI: battery: Add synchronization between interface updates
There is no synchronization between different code paths in the ACPI
battery driver that update its sysfs interface or its power supply
class device interface.  In some cases this results to functional
failures due to race conditions.

One example of this is when two ACPI notifications:

  - ACPI_BATTERY_NOTIFY_STATUS (0x80)
  - ACPI_BATTERY_NOTIFY_INFO   (0x81)

are triggered (by the platform firmware) in a row with a little delay
in between after removing and reinserting a laptop battery.  Both
notifications cause acpi_battery_update() to be called and if the delay
between them is sufficiently small, sysfs_add_battery() can be re-entered
before battery->bat is set which leads to a duplicate sysfs entry error:

 sysfs: cannot create duplicate filename '/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT1'

 kobject: kobject_add_internal failed for BAT1 with -EEXIST, don't try to register things with the same name in the same directory.

There are also other scenarios in which analogous issues may occur.

Address this by using a common lock in all of the code paths leading
to updates of driver interfaces: ACPI Notify () handler, system resume
callback and post-resume notification, device addition and removal.

This new lock replaces sysfs_lock that has been used only in
sysfs_remove_battery() which now is going to be always called under
the new lock, so it doesn't need any internal locking any more.

Kumar Kartikeya Dwivedi 15cf39221e selftests/bpf: Add stress test for rqspinlock in NMI
Introduce a kernel module that will exercise lock acquisition in the NMI
path, and bias toward creating contention such that NMI waiters end up
being non-head waiters. Prior to the rqspinlock fix made in the commit
0d80e7f951 ("rqspinlock: Choose trylock fallback for NMI waiters"), it
was possible for the queueing path of non-head waiters to get stuck in
NMI, which this stress test reproduces fairly easily with just 3 CPUs.

Both AA and ABBA flavors are supported, and it will serve as a test case
for future fixes that address this corner case. More information about
the problem in question is available in the commit cited above. When the
fix is reverted, this stress test will lock up the system.

To enable this test automatically through the test_progs infrastructure,
add a load_module_params API to exercise both AA and ABBA cases when
running the test.

Note that the test runs for at most 5 seconds, and becomes a noop after
that, in order to allow the system to make forward progress. In
addition, CPU 0 is always kept untouched by the created threads and
NMIs. The test will automatically scale to the number of available
online CPUs.

Note that at least 3 CPUs are necessary to run this test, hence skip the
selftest in case the environment has less than 3 CPUs available.

to support balance ID in multiplane LAG configurations.

The new fields include:
- load_balance_id: 4-bit field for balance identifier.
- lag_per_mp_group: capability bit for LAG per multiplane group support.

These interface additions are prerequisites for implementing balance ID

Jeongjun Park 9f2c0ac142 ALSA: usb-audio: fix race condition to UAF in snd_usbmidi_free
The previous commit 0718a78f6a ("ALSA: usb-audio: Kill timer properly at
removal") patched a UAF issue caused by the error timer.

However, because the error timer kill added in this patch occurs after the
endpoint delete, a race condition to UAF still occurs, albeit rarely.

Additionally, since kill-cleanup for urb is also missing, freed memory can
be accessed in interrupt context related to urb, which can cause UAF.

Therefore, to prevent this, error timer and urb must be killed before
freeing the heap memory.

Fan Wu 5851afffe2 KEYS: X.509: Fix Basic Constraints CA flag parsing
Fix the X.509 Basic Constraints CA flag parsing to correctly handle
the ASN.1 DER encoded structure. The parser was incorrectly treating
the length field as the boolean value.

Per RFC 5280 section 4.1, X.509 certificates must use ASN.1 DER encoding.
According to ITU-T X.690, a DER-encoded BOOLEAN is represented as:

Tag (0x01), Length (0x01), Value (0x00 for FALSE, 0xFF for TRUE)

The basicConstraints extension with CA:TRUE is encoded as:

  SEQUENCE (0x30) | Length | BOOLEAN (0x01) | Length (0x01) | Value (0xFF)
                             ^-- v[2]         ^-- v[3]        ^-- v[4]

The parser was checking v[3] (the length field, always 0x01) instead
of v[4] (the actual boolean value, 0xFF for TRUE in DER encoding).

Also handle the case where the extension is an empty SEQUENCE (30 00),
which is valid for CA:FALSE when the default value is omitted as
required by DER encoding rules (X.690 section 11.5).

Per ITU-T X.690-0207:
- Section 11.5: Default values must be omitted in DER
- Section 11.1: DER requires TRUE to be encoded as 0xFF

Al Viro 2f7d98f10b Have cc(1) catch attempts to modify ->f_path
There are very few places that have cause to do that - all in core
VFS now, and all done to files that are not yet opened (or visible
to anybody else, for that matter).

Let's turn f_path into a union of struct path __f_path and const
struct path f_path.  It's C, not C++ - 6.5.2.3[4] in C99 and
later explicitly allows that kind of type-punning.

That way any attempts to bypass these checks will be either very
easy to catch, or (if the bastards get sufficiently creative to
make it hard to spot with grep alone) very clearly malicious -
and still catchable with a bit of instrumentation for sparse.

Instead of switching ->f_path.mnt of an opened file to internal
clone, get a struct path with ->mnt set to internal clone of that
->f_path.mnt, then dentry_open() that to get the file with right ->f_path.mnt
from the very beginning.

	The only subtle part here is that on failure exits we need to
close the file with __fput_sync() and make sure we do that *before*
dropping the original mount.

	With that done, only fs/{file_table,open,namei}.c ever store
anything to file->f_path and only prior to file->f_mode & FMODE_OPENED
becoming true.  Analysis of mount write count handling also becomes
less brittle and convoluted...

[AV: folded a fix for a bug spotted by Jan Kara - we do need a full-blown
open of the original file, not just user_path_at() or we end up skipping
permission checks]

Sven Eckelmann f12b69d8f2 batman-adv: Release references to inactive interfaces
Trying to dump the originators or the neighbors via netlink for a meshif
with an inactive primary interface is not allowed. The dump functions were
checking this correctly but they didn't handle non-existing primary
interfaces and existing _inactive_ interfaces differently.

(Primary) batadv_hard_ifaces hold a references to a net_device. And
accessing them is only allowed when either being in a RCU/spinlock
protected section or when holding a valid reference to them. The netlink
dump functions use the latter.

But because the missing specific error handling for inactive primary
interfaces, the reference was never dropped. This reference counting error
was only detected when the interface should have been removed from the
system:

  unregister_netdevice: waiting for batadv_slave_0 to become free. Usage count = 2
