kernel:
Stephane Eranian :
- Restore mmap record type correctly when handling PERF_RECORD_MMAP2
events, as the same template is used for all the threads interested
in mmap events, some may want just PERF_RECORD_MMAP, while some
may want the extra info in MMAP2 records.
perf probe:
Adrian Hunter:
- Fix getting the kernel map, because since changes related to x86 PTI
entry trampolines handling, there are more than one kernel map.
perf script:
Andi Kleen:
- Support insn output for normal samples, i.e.:
perf script -F ip,sym,insn --xed
Will fetch the sample IP from the thread address space and feed it
to Intel's XED disassembler, producing lines such as:
ffffffffa4068804 native_write_msr wrmsr
ffffffffa415b95e __hrtimer_next_event_base movq 0x18(%rax), %rdx
That match 'perf annotate's output.
- Make the --cpu filter apply to PERF_RECORD_COMM/FORK/... events, in
addition to PERF_RECORD_SAMPLE.
perf report:
- Add a new --samples option to save a small random number of samples
per hist entry, using a reservoir technique to select a representative
number of samples.
Then allow browsing the samples using 'perf script' as part of the hist
entry context menu. This automatically adds the right filters, so only
the thread or CPU of the sample is displayed. Then we use less' search
functionality to directly jump to the time stamp of the selected sample.
It uses different menus for assembler and source display. Assembler
needs xed installed and source needs debuginfo.
- Fix the UI browser scripts pop up menu when there are many scripts
available.
perf report:
Andi Kleen:
- Add 'time' sort option. E.g.:
% perf report --sort time,overhead,symbol --time-quantum 1ms --stdio

One fix for a boot failure on 32-bit, introduced during the merge window.
A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall
clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and
backward.
Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some
systems it was reporting that the count cache was disabled and also that we were
flushing the count cache on context switch. Only the former is true, and given
that the count cache is disabled it doesn't make any sense to flush it. No one
reported it, so presumably the presence of any mitigation is all people check
for.
Finally a small build fix for zsmalloc on 32-bit.

ca0132 codec driver loads the firmware selectively depending on the
model in addition to the fallback of the default firmware. The code
works good, but a minor problem is that the current code seems
confusing for Clang where it spews a warning about uninitialized
variable.
This patch simplifies the code flow for such a false-positive
warning. After this refactoring, the ca0132_spec.alt_firmware_present
field is no longer used, hence it's eliminated as well.

Commit 2f31a67f01 ("usb: xhci: Prevent bus suspend if a port connect
change or polling state is detected") was intended to prevent ports that
were still link training from being forced to U3 suspend state mid
enumeration.
This solved enumeration issues for devices with slow link training.
Turns out some devices are stuck in the link training/polling state,
and thus that patch will prevent suspend completely for these devices.
This is seen with USB3 card readers in some MacBooks.
Instead of preventing suspend, give some time to complete the link
training. On successful training the port will end up as connected
and enabled.
If port instead is stuck in link training the bus suspend will continue
suspending after 360ms (10 * 36ms) timeout (tPollingLFPSTimeout).
Original patch was sent to stable, this one should go there as well

A suspended SS port in U3 link state will go to U0 when resumed, but
can almost immediately after that enter U1 or U2 link power save
states before host controller driver reads the port status.
Host controller driver only checks for U0 state, and might miss
the finished resume, leaving flags unclear and skip notifying usb
code of the wake.
Add U1 and U2 to the possible link states when checking for finished
port resume.

The PCM OSS emulation converts and transfers the data on the fly via
"plugins". The data is converted over the dynamically allocated
buffer for each plugin, and recently syzkaller caught OOB in this
flow.
Although the bisection by syzbot pointed out to the commit
65766ee0bf ("ALSA: oss: Use kvzalloc() for local buffer
allocations"), this is merely a commit to replace vmalloc() with
kvmalloc(), hence it can't be the cause. The further debug action
revealed that this happens in the case where a slave PCM doesn't
support only the stereo channels while the OSS stream is set up for a
mono channel. Below is a brief explanation:
At each OSS parameter change, the driver sets up the PCM hw_params
again in snd_pcm_oss_change_params_lock(). This is also the place
where plugins are created and local buffers are allocated. The
problem is that the plugins are created before the final hw_params is
determined. Namely, two snd_pcm_hw_param_near() calls for setting the
period size and periods may influence on the final result of channels,
rates, etc, too, while the current code has already created plugins
beforehand with the premature values. So, the plugin believes that
channels=1, while the actual I/O is with channels=2, which makes the
driver reading/writing over the allocated buffer size.
The fix is simply to move the plugin allocation code after the final
hw_params call.

The futex code requires that the user space addresses of futexes are 32bit
aligned. sys_futex() checks this in futex_get_keys() but the robust list
code has no alignment check in place.
As a consequence the kernel crashes on architectures with strict alignment
requirements in handle_futex_death() when trying to cmpxchg() on an
unaligned futex address which was retrieved from the robust list.

Commit 7640ead939 ("bpf: verifier: make sure callees don't prune
with caller differences") connected up parentage chains of all
frames of the stack. It didn't, however, ensure propagate_liveness()
propagates all liveness information along those chains.
This means pruning happening in the callee may generate explored
states with incomplete liveness for the chains in lower frames
of the stack.
The included selftest is similar to the prior one from commit
7640ead939 ("bpf: verifier: make sure callees don't prune with
caller differences"), where callee would prune regardless of the
difference in r8 state.
Now we also initialize r9 to 0 or 1 based on a result from get_random().
r9 is never read so the walk with r9 = 0 gets pruned (correctly) after
the walk with r9 = 1 completes.
The selftest is so arranged that the pruning will happen in the
callee. Since callee does not propagate read marks of r8, the
explored state at the pruning point prior to the callee will
now ignore r8.
Propagate liveness on all frames of the stack when pruning.
