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.

Reads on tpm/tpm0/ppi/*operations can become very long on
misconfigured systems. Reading the TPM is a blocking operation,
thus a user could effectively trigger a DOS.
Resolve this by caching the results and avoiding the blocking
operations after the first read.

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spec after the feature was originally made.

Now that there are easy-to-use HMAC-SHA256 library functions, use these
in tpm2-sessions.c instead of open-coding the HMAC algorithm.
Note that the new implementation correctly handles keys longer than 64
bytes (SHA256_BLOCK_SIZE), whereas the old implementation handled such
keys incorrectly. But it doesn't appear that such keys were being used.

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().

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.

On NT systems, it is possible to do SMB open call also for directories.
Open argument CREATE_NOT_DIR disallows opening directories. So in fallback

Similar fallback is implemented also in CIFSSMBSetPathInfoFB() function and

A regression was reported to me recently whereby /dev/fb0 had disappeared
from a PowerBook G3 Series "Wallstreet". The problem shows up when the
"video=ofonly" parameter is passed to the kernel, which is what the
bootloader does when "no video driver" is selected. The cause of the
problem is the "offb" string comparison, which got mangled when it got
refactored. Fix it.

When setting a normal alarm, user-space is responsible for using
RTC_AIE_ON/RTC_AIE_OFF to control if alarm irq should be enabled.
But when RTC_UIE_ON is used, interrupts must be enabled so that the
requested irq events are generated.
When RTC_UIE_OFF is used, alarm irq is disabled if there are no other
alarms queued, so this commit brings symmetry to that.

As described in the old comment dating back to
commit 6610e0893b8b ("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.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
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()
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.

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.

Don't call ->set_file_info() on open handle to prevent the server from
stopping [cm]time updates automatically as per MS-FSA 2.1.4.17.
Fix this by checking for ATTR_OPEN bit earlier in cifs_setattr() to
prevent ->set_file_info() from being called when opening a file with
O_TRUNC. Do the truncation in ->open() instead.
This also saves two roundtrips when opening a file with O_TRUNC and
there are currently no open handles to be reused.

smb2_copychunk_range() used to send a single SRV_COPYCHUNK per
SRV_COPYCHUNK_COPY IOCTL.
Implement variable Chunks[] array in struct copychunk_ioctl and fill it
with struct copychunk (MS-SMB2 2.2.31.1.1), bounded by server-advertised
limits.
This reduces the number of IOCTL requests for large copies.

====================
eth: fbnic: fix XDP_TX and XDP vs qstats
Fix XDP_TX hangs and adjust the XDP statistics to match the definition
of qstats. The three problems are somewhat distinct.
XDP_TX hangs is a simple coding bug (patch 1).
The accounting of XDP packets is all over the place. Fix it to obey
qstat rules (packets seen by XDP always counted as Rx packets).
Patch 2 fixes the basic accounting, patch 3 touches up saving
the stats when rings are freed.
Patch 6 corrects reporting of alloc_fail stats which prevented
the pp_alloc_fail test from passing.
Patches 4, 5, 7, 8, 9 add or fix related test cases.
v2:
- [patch 2] remove now unnecessary byte adjustment
- [patch 8] use seen_fails more

Lower the expected level of traffic in the pp_alloc_fail test
and calculate failure counter thresholds based on the traffic
rather than using a fixed constant.
We only have "QEMU HW" in NIPA right now, and the test (due to
debug dependencies) only works on debug kernels in the first place.
We need some place for it to pass otherwise it seems to be bit
rotting. So lower the traffic threshold so that it passes on QEMU
and with a debug kernel...

Rx processing under normal circumstances has 3 rings - 2 buffer
rings (heads, payloads) and a completion ring. All the rings
have a struct fbnic_ring. Make sure we expose alloc_failed
counter from the buffer rings, previously only the alloc_failed
from the completion ring was reported, even tho all ring types
may increment this counter (buffer rings in __fbnic_fill_bdq()).
This makes the pp_alloc_fail.py test pass, it expects the qstat
to be incrementing as page pool injections happen.
