fdfa38e95e sound fixes for 6.18-rc1
A few more small fixes for 6.18-rc1.
 Most of changes are about ASoC Intel and SOF drivers, while a few
 other device-specific fixes are found for HD-audio, USB-audio, ASoC
 RT722VB and Meson.

84d4e8b613 Hi,
Round #2.
 
 O_EXCL patches will be postponed to 6.19 as they need some restructuring.
 E.g., there's in-between series regression breaking the user space as lack
 of O_EXCL flag handling causes obviously unconditional O_EXCL.
 
 As per Chris' feedback, commands fail because it is based on Google's a
 non-standard proprietary TPM alike implementation. And the issue is not
 PC Client Profile specific. "typical profiles" are fine when they become
 "typical profiles".
 
 The null key can be verified with vendor certificate tied keys, and there's
 challenge-response process using them for certifying any other key by a
 remote party.
 
 Performance hit on generation aside, if really starting to cut hairs null
 keys are the most secure option, and it's a non-debatable fact: they have
 shortest expiration times as seed changes per power cycle.
 
 Based on this TCG_TPM2_HMAC is disabled from defconfig exactly for the sake
 of the performance issues.
 
 BR, Jarkko

The ozlabs.org PW instance is slow due to being geographically far away
from any of the maintainers and seems to have gotten slower as of late
(AI scrapers perhaps). The kernel.org PW also has some additional
features (i.e. pwbot) we want to use.

DT core patches also go into PW, so add the PW link for it.

ovl: remove redundant IOCB_DIO_CALLER_COMP clearing
The backing_file_write_iter() function, which is called

logic to clear the IOCB_DIO_CALLER_COMP flag along with

Revert "fs: make vfs_fileattr_[get|set] return -EOPNOTSUPP"
This reverts commit 474b155adf.

This patch caused regression in ioctl_setflags(). Underlying filesystems
use EOPNOTSUPP to indicate that flag is not supported. This error is

207696b17f tpm: use a map for tpm2_calc_ordinal_duration()
The current shenanigans for duration calculation introduce too much
complexity for a trivial problem, and further the code is hard to patch and
maintain.

Address these issues with a flat look-up table, which is easy to understand
and patch. If leaf driver specific patching is required in future, it is
easy enough to make a copy of this table during driver initialization and
add the chip parameter back.

'chip->duration' is retained for TPM 1.x.

As the first entry for this new behavior address TCG spec update mentioned
in this issue:

https://github.com/raspberrypi/linux/issues/7054

Therefore, for TPM_SelfTest the duration is set to 3000 ms.

This does not categorize a as bug, given that this is introduced to the
spec after the feature was originally made.

2c2615c842 tpm: Compare HMAC values in constant time
In tpm_buf_check_hmac_response(), compare the HMAC values in constant
time using crypto_memneq() instead of in variable time using memcmp().

This is worthwhile to follow best practices and to be consistent with
MAC comparisons elsewhere in the kernel.  However, in this driver the
side channel seems to have been benign: the HMAC input data is
guaranteed to always be unique, which makes the usual MAC forgery via
timing side channel not possible.  Specifically, the HMAC input data in
tpm_buf_check_hmac_response() includes the "our_nonce" field, which was
generated by the kernel earlier, remains under the control of the
kernel, and is unique for each call to tpm_buf_check_hmac_response().

4bddf4587c tpm: Disable TPM2_TCG_HMAC by default
After reading all the feedback, right now disabling the TPM2_TCG_HMAC
is the right call.

Other views discussed:

A. Having a kernel command-line parameter or refining the feature
   otherwise. This goes to the area of improvements.  E.g., one
   example is my own idea where the null key specific code would be
   replaced with a persistent handle parameter (which can be
   *unambigously* defined as part of attestation process when
   done correctly).

B. Removing the code. I don't buy this because that is same as saying
   that HMAC encryption cannot work at all (if really nitpicking) in
   any form. Also I disagree on the view that the feature could not
   be refined to something more reasoable.

Also, both A and B are worst options in terms of backporting.

Thuss, this is the best possible choice.

ae9e9f3d67 RISC-V: clear hot-unplugged cores from all task mm_cpumasks to avoid rfence errors
openSBI v1.7 adds harts checks for ipi operations. Especially it
adds comparison between hmask passed as an argument from linux
and mask of online harts (from openSBI side). If they don't
fit each other the error occurs.

When cpu is offline, cpu_online_mask is explicitly cleared in
__cpu_disable. However, there is no explicit clearing of
mm_cpumask. mm_cpumask is used for rfence operations that
call openSBI RFENCE extension which uses ipi to remote harts.
If hart is offline there may be error if mask of linux is not
as mask of online harts in openSBI.

this patch adds explicit clearing of mm_cpumask for offline hart.

781380d2cd riscv: kgdb: Ensure that BUFMAX > NUMREGBYTES
The current value of BUFMAX is similar as in other architectures, but as
per documentation on KGDB (see
'Documentation/process/debugging/kgdb.rst'), BUFMAX has to be larger
than NUMREGBYTES.

Some NUMREGBYTES architectures (e.g. powerpc or hexagon) actually define
BUFMAX in relation to NUMREGBYTES, and thus this condition is always
guaranteed. Since 2048 is a value that is generally accepted on all
architectures, and that is larger than the current value of NUMREGBYTES,
we can keep this value in arch/riscv, but we can at least add an
'static_assert' as an extra measure just in case NUMREGBYTES changes in
the future for some unforseen reason.

812258ff41 rust: cfi: only 64-bit arm and x86 support CFI_CLANG
The kernel uses the standard rustc targets for non-x86 targets, and out
of those only 64-bit arm's target has kcfi support enabled. For x86, the
custom 64-bit target enables kcfi.

The HAVE_CFI_ICALL_NORMALIZE_INTEGERS_RUSTC config option that allows
CFI_CLANG to be used in combination with RUST does not check whether the
rustc target supports kcfi. This breaks the build on riscv (and
presumably 32-bit arm) when CFI_CLANG and RUST are enabled at the same
time.

Ordinarily, a rustc-option check would be used to detect target support
but unfortunately rustc-option filters out the target for reasons given
in commit 46e24a545c ("rust: kasan/kbuild: fix missing flags on first
build"). As a result, if the host supports kcfi but the target does not,
e.g. when building for riscv on x86_64, the build would remain broken.

Instead, make HAVE_CFI_ICALL_NORMALIZE_INTEGERS_RUSTC depend on the only
two architectures where the target used supports it to fix the build.

When setting a normal alarm, user-space is responsible for using

But when RTC_UIE_ON is used, interrupts must be enabled so that the

795cda8338 rtc: interface: Fix long-standing race when setting alarm
As described in the old comment dating back to
commit 6610e0893b ("RTC: Rework RTC code to use timerqueue for events")
from 2010, we have been living with a race window when setting alarm
with an expiry in the near future (i.e. next second).
With 1 second resolution, it can happen that the second ticks after the
check for the timer having expired, but before the alarm is actually set.
When this happen, no alarm IRQ is generated, at least not with some RTC
chips (isl12022 is an example of this).

With UIE RTC timer being implemented on top of alarm irq, being re-armed
every second, UIE will occasionally fail to work, as an alarm irq lost
due to this race will stop the re-arming loop.

For now, I have limited the additional expiry check to only be done for
alarms set to next seconds. I expect it should be good enough, although I
don't know if we can now for sure that systems with loads could end up
causing the same problems for alarms set 2 seconds or even longer in the
future.

I haven't been able to reproduce the problem with this check in place.

5472d60c12 tracing clean up and fixes for v6.18:
- Have osnoise tracer use memdup_user_nul()
 
   The function osnoise_cpus_write() open codes a kmalloc() and then
   a copy_from_user() and then adds a nul byte at the end which is the
   same as simply using memdup_user_nul().
 
 - Fix wakeup and irq tracers when failing to acquire calltime
 
   When the wakeup and irq tracers use the function graph tracer for
   tracing function times, it saves a timestamp into the fgraph shadow
   stack. It is possible that this could fail to be stored. If that
   happens, it exits the routine early. These functions also disable
   nesting of the operations by incremeting the data "disable" counter.
   But if the calltime exits out early, it never increments the counter
   back to what it needs to be.
 
   Since there's only a couple of lines of code that does work after
   acquiring the calltime, instead of exiting out early, reverse the
   if statement to be true if calltime is acquired, and place the code
   that is to be done within that if block. The clean up will always
   be done after that.
 
 - Fix ring_buffer_map() return value on failure of __rb_map_vma()
 
   If __rb_map_vma() fails in ring_buffer_map(), it does not return
   an error. This means the caller will be working against a bad vma
   mapping. Have ring_buffer_map() return an error when __rb_map_vma()
   fails.
 
 - Fix regression of writing to the trace_marker file
 
   A bug fix was made to change __copy_from_user_inatomic() to
   copy_from_user_nofault() in the trace_marker write function.
   The trace_marker file is used by applications to write into
   it (usually with a file descriptor opened at the start of the
   program) to record into the tracing system. It's usually used
   in critical sections so the write to trace_marker is highly
   optimized.
 
   The reason for copying in an atomic section is that the write
   reserves space on the ring buffer and then writes directly into
   it. After it writes, it commits the event. The time between
   reserve and commit must have preemption disabled.
 
   The trace marker write does not have any locking nor can it
   allocate due to the nature of it being a critical path.
 
   Unfortunately, converting __copy_from_user_inatomic() to
   copy_from_user_nofault() caused a regression in Android.
   Now all the writes from its applications trigger the fault that
   is rejected by the _nofault() version that wasn't rejected by
   the _inatomic() version. Instead of getting data, it now just
   gets a trace buffer filled with:
 
     tracing_mark_write: <faulted>
 
   To fix this, on opening of the trace_marker file, allocate
   per CPU buffers that can be used by the write call. Then
   when entering the write call, do the following:
 
     preempt_disable();
     cpu = smp_processor_id();
     buffer = per_cpu_ptr(cpu_buffers, cpu);
     do {
 	cnt = nr_context_switches_cpu(cpu);
 	migrate_disable();
 	preempt_enable();
 	ret = copy_from_user(buffer, ptr, size);
 	preempt_disable();
 	migrate_enable();
     } while (!ret && cnt != nr_context_switches_cpu(cpu));
     if (!ret)
 	ring_buffer_write(buffer);
     preempt_enable();
 
   This works similarly to seqcount. As it must enabled preemption
   to do a copy_from_user() into a per CPU buffer, if it gets
   preempted, the buffer could be corrupted by another task.
   To handle this, read the number of context switches of the current
   CPU, disable migration, enable preemption, copy the data from
   user space, then immediately disable preemption again.
   If the number of context switches is the same, the buffer
   is still valid. Otherwise it must be assumed that the buffer may
   have been corrupted and it needs to try again.
 
   Now the trace_marker write can get the user data even if it has
   to fault it in, and still not grab any locks of its own.

Pull tracing clean up and fixes from Steven Rostedt:

 - Have osnoise tracer use memdup_user_nul()

   The function osnoise_cpus_write() open codes a kmalloc() and then a
   copy_from_user() and then adds a nul byte at the end which is the
   same as simply using memdup_user_nul().

 - Fix wakeup and irq tracers when failing to acquire calltime

   When the wakeup and irq tracers use the function graph tracer for
   tracing function times, it saves a timestamp into the fgraph shadow
   stack. It is possible that this could fail to be stored. If that
   happens, it exits the routine early. These functions also disable
   nesting of the operations by incremeting the data "disable" counter.
   But if the calltime exits out early, it never increments the counter
   back to what it needs to be.

   Since there's only a couple of lines of code that does work after
   acquiring the calltime, instead of exiting out early, reverse the if
   statement to be true if calltime is acquired, and place the code that
   is to be done within that if block. The clean up will always be done
   after that.

 - Fix ring_buffer_map() return value on failure of __rb_map_vma()

   If __rb_map_vma() fails in ring_buffer_map(), it does not return an
   error. This means the caller will be working against a bad vma
   mapping. Have ring_buffer_map() return an error when __rb_map_vma()

dba9f997c9 smb: client: fix race with fallocate(2) and AIO+DIO
AIO+DIO may extend the file size, hence we need to make sure ->i_size
is stable across the entire fallocate(2) operation, otherwise it would
become a truncate and then inode size reduced back down when it
finishes.

Fix this by calling netfs_wait_for_outstanding_io() right after
acquiring ->i_rwsem exclusively in cifs_fallocate() and then guarantee
a stable ->i_size across fallocate(2).

Also call netfs_wait_for_outstanding_io() after truncating pagecache
to avoid any potential races with writeback.
