444c897111 selftests: net: bridge: add initial MLDv2 include test
Add the initial setup for MLDv2 tests with the first test of a simple
is_include report. For MLDv2 we need to setup the bridge properly and we
also send the full precooked packets instead of relying on mausezahn to
fill in some parts. For verification we use the generic S,G state checking
functions from lib.sh.

644bf4b0f7 perf jevents: Add test for arch std events
Recently there was an undetected breakage for std arch event support.

Add support in "PMU events" testcase to detect such breakages.

For this, the "test" arch needs has support added to process std arch
events. And a test event is added for the test, ifself.

Also add a few code comments to help understand the code a bit better.

Committer testing:

Before:

  # perf test -vv pmu  |& grep l3_cache_rd
  #

After:

  # perf test -vv pmu  |& grep l3_cache_rd
  testing event table l3_cache_rd: pass
  testing aliases PMU cpu: matched event l3_cache_rd

55a4de94c6 perf stat: Add --quiet option
Add a new --quiet option to 'perf stat'. This is useful with 'perf stat
record' to write the data only to the perf.data file, which can lower
measurement overhead because the data doesn't need to be formatted.

On my 4C desktop:

  % time ./perf stat record  -e $(python -c 'print ",".join(["cycles"]*1000)')  -a -I 1000 sleep 5
  ...
  real    0m5.377s
  user    0m0.238s
  sys     0m0.452s
  % time ./perf stat record --quiet -e $(python -c 'print ",".join(["cycles"]*1000)')  -a -I 1000 sleep 5

  real    0m5.452s
  user    0m0.183s
  sys     0m0.423s

In this example it cuts the user time by 20%. On systems with more cores
the savings are higher.

x86 arch provides the testing for conversion between tsc and perf time,
the testing is located in x86 arch folder.  Move this testing out from
x86 arch folder and place it into the common testing folder, so allows

This patch removes the inclusion of "arch-tests.h" from the testing
code, this can avoid building failure if any arch has no this header
file.

0ee281e1e4 perf mem2node: Improve warning if detected no memory nodes
Some archs (e.g. x86 and Arm64) don't enable the configuration
CONFIG_MEMORY_HOTPLUG by default, if this configuration is not enabled
when build the kernel image, the SysFS for memory nodes will be missed.
This results in perf tool has no chance to catpure the memory nodes
information, when perf tool reports the result and detects no memory
nodes, it outputs "assertion failed at util/mem2node.c:99".

The output log doesn't give out reason for the failure and users have no
clue for how to fix it.  This patch changes to use explicit way for
warning: it tells user that detected no memory nodes and suggests to
enable CONFIG_MEMORY_HOTPLUG for kernel building.

0a099d1429 selftests/bpf: Migrate tcpbpf_user.c to use BPF skeleton
Update tcpbpf_user.c to make use of the BPF skeleton. Doing this we can
simplify test_tcpbpf_user and reduce the overhead involved in setting up
the test.

In addition we can clean up the remaining bits such as the one remaining
CHECK_FAIL at the end of test_tcpbpf_user so that the function only makes
use of CHECK as needed.

d3813ea14b selftests/bpf: Replace EXPECT_EQ with ASSERT_EQ and refactor verify_results
There is already logic in test_progs.h for asserting that a value is
expected to be another value. So instead of reinventing it we should just
make use of ASSERT_EQ in tcpbpf_user.c. This will allow for better
debugging and integrates much more closely with the test_progs framework.

In addition we can refactor the code a bit to merge together the two
verify functions and tie them together into a single function. Doing this
helps to clean the code up a bit and makes it more readable as all the
verification is now done in one function.

Lastly we can relocate the verification to the end of the run_test since it
is logically part of the test itself. With this we can drop the need for a
return value from run_test since verification becomes the last step of the
call and then immediately following is the tear down of the test setup.

247f0ec361 selftests/bpf: Drop python client/server in favor of threads
Drop the tcp_client/server.py files in favor of using a client and server
thread within the test case. Specifically we spawn a new thread to play the
role of the server, and the main testing thread plays the role of client.

Add logic to the end of the run_test function to guarantee that the sockets
are closed when we begin verifying results.

Doing this we are able to reduce overhead since we don't have two python
workers possibly floating around. In addition we don't have to worry about
synchronization issues and as such the retry loop waiting for the threads
to close the sockets can be dropped as we will have already closed the
sockets in the local executable and synchronized the server thread.

aaf376bddf selftests/bpf: Move test_tcppbf_user into test_progs
Recently a bug was missed due to the fact that test_tcpbpf_user is not a
part of test_progs. In order to prevent similar issues in the future move
the test functionality into test_progs. By doing this we can make certain
that it is a part of standard testing and will not be overlooked.

As a part of moving the functionality into test_progs it is necessary to
integrate with the test_progs framework and to drop any redundant code.
This patch:
1. Cleans up the include headers
2. Dropped a duplicate definition of bpf_find_map
3. Switched over to using test_progs specific cgroup functions
4. Renamed main to test_tcpbpf_user
5. Dropped return value in favor of CHECK_FAIL to check for errors

The general idea is that I wanted to keep the changes as small as possible
while moving the file into the test_progs framework. The follow-on patches
are meant to clean up the remaining issues such as the use of CHECK_FAIL.

 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

e6b0bd61a7 This pull contains a series of warning fixes from Mauro; once applied, the
number of warnings from the once-noisy docs build process is nearly zero.
 Getting to this point has required a lot of work; once there, hopefully we
 can keep things that way.
 
 I have packaged this as a separate pull because it does a fair amount of
 reaching outside of Documentation/.  The changes are all in comments and in
 code placement.  It's all been in linux-next since last week.

To pick the changes from:

  dab741e0e02bd3c4 ("Add a "nosymfollow" mount option.")

That ends up adding support for the new MS_NOSYMFOLLOW mount flag:

So now one can use it in --filter expressions for tracepoints.

aa04899a13 tools kvm headers: Update KVM headers from the kernel sources
Some should cause changes in tooling, like the one adding LAST_EXCP, but
the way it is structured end up not making that happen.

The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c,
in the svm_exit_reasons table.

The tools/perf/trace/beauty part has scripts to catch changes and
automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh,
but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch
those automatically.

These were handled by the existing scripts:
