mm/rmap: fix old bug: munlocking THP missed other mlocks

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.

It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped.  Refine the tests.

There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.

(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

mm/page_alloc: Revert pahole zero-sized workaround

Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to
local_lock") folded in a workaround patch for pahole that was unable to
deal with zero-sized percpu structures.

A superior workaround is achieved with commit a0b8200d06ad ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").

This patch reverts the dummy field and the pahole version check.

added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:

[  121.248971] Disabling IRQ #78

Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.

However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

SMB3.1.1: Add support for negotiating signing algorithm

Support for faster packet signing (using GMAC instead of CMAC) can
now be negotiated to some newer servers, including Windows.
See MS-SMB2 section 2.2.3.17.

This patch adds support for sending the new negotiate context
with the first of three supported signing algorithms (AES-CMAC)
and decoding the response.  A followon patch will add support
for sending the other two (including AES-GMAC, which is fastest)
and changing the signing algorithm used based on what was
negotiated.

To allow the client to request GMAC signing set module parameter
"enable_negotiate_signing" to 1.

3 years agoperf tools: Fix pattern matching for same substring in different PMU type
Jin Yao [Thu, 1 Jul 2021 06:42:53 +0000 (14:42 +0800)]
perf tools: Fix pattern matching for same substring in different PMU type

Some different PMU types may have the same substring. For example, on
Icelake server we have PMU types "uncore_imc" and
"uncore_imc_free_running". Both PMU types have the substring
"uncore_imc".  But the parser wrongly thinks they are the same PMU type.

We enable an imc event,
perf stat -e uncore_imc/event=0xe3/ -a -- sleep 1

Perf actually expands the event to:

  uncore_imc_0/event=0xe3/
  uncore_imc_1/event=0xe3/
  uncore_imc_2/event=0xe3/
  uncore_imc_3/event=0xe3/
  uncore_imc_4/event=0xe3/
  uncore_imc_5/event=0xe3/
  uncore_imc_6/event=0xe3/
  uncore_imc_7/event=0xe3/
  uncore_imc_free_running_0/event=0xe3/
  uncore_imc_free_running_1/event=0xe3/
  uncore_imc_free_running_3/event=0xe3/
  uncore_imc_free_running_4/event=0xe3/

That's because the "uncore_imc_free_running" matches the
pattern "uncore_imc*".

Now we check that the last characters of PMU name is '_<digit>'.

For example, for pattern "uncore_imc*", "uncore_imc_0" is parsed ok, but
"uncore_imc_free_running_0" fails.

3 years agoperf record: Add a dummy event on hybrid systems to collect metadata records
Kan Liang [Thu, 8 Jul 2021 16:03:32 +0000 (09:03 -0700)]
perf record: Add a dummy event on hybrid systems to collect metadata records

Some symbols may not be resolved if a user only monitors one type of
PMU.

  $ sudo perf record -e cpu_atom/branch-instructions/ ./big_small_workload
  $ sudo perf report –stdio
  # Overhead  Command    Shared Object      Symbol
  # ........  .........  .................  .....................
  #
     28.02%  perf-exec  [unknown]          [.] 0x0000000000401cf6
     11.32%  perf-exec  [unknown]          [.] 0x0000000000401d04
     10.90%  perf-exec  [unknown]          [.] 0x0000000000401d11
     10.61%  perf-exec  [unknown]          [.] 0x0000000000401cfc

To parse symbols the metadata records, e.g., PERF_RECORD_COMM, which are
generated by the kernel, are required.

To decide whether to generate the metadata records, the kernel relies on
the event_filter_match() to filter the unrelated events.

On a hybrid system, event_filter_match() further checks the CPU mask of
the current enabled PMU. If an event is collected on the CPU which
doesn't have an enabled PMU, it's treated as an unrelated event.

The "big_small_workload" is created in a big core, but runs on a small
core. The metadata records are filtered, because the user only monitors
the PMU of the small core. The big core PMU is not enabled.

For a hybrid system, a dummy event is required to generate the complete
side-band events.
