tools headers: Synchronize linux/bits.h with the kernel sources (2020-04-14 11:40:05 -0300)
----------------------------------------------------------------
perf/urgent fixes:
perf stat:
Jin Yao:
- Fix no metric header if --per-socket and --metric-only set
build system:
- Fix python building when built with clang, that was failing if the clang
version doesn't support -fno-semantic-interposition.
tools UAPI headers:
Arnaldo Carvalho de Melo:
- Update various copies of kernel headers, some ended up automatically
updating build-time generated tables to enable tools such as 'perf trace'
to decode syscalls and tracepoints arguments.
Now the tools/perf build is free of UAPI drift warnings.

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.
Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

It builds ok with the default set of options.

The set of C compiler options used by distros to build python bindings
may include options that are unknown to clang, we check for a variety of
such options, add -fno-semantic-interposition to that mix:
This fixes the build on, among others, Manjaro Linux:
GEN /tmp/build/perf/python/perf.so
clang-9: error: unknown argument: '-fno-semantic-interposition'

We received a report that was no metric header displayed if --per-socket
and --metric-only were both set.
It's hard for script to parse the perf-stat output. This patch fixes this
issue.
Before:

Picking the changes from:
455e00f1412f ("drm: Add getfb2 ioctl")
Silencing these perf build warnings:
Warning: Kernel ABI header at 'tools/include/uapi/drm/drm.h' differs from latest version at 'include/uapi/drm/drm.h'
diff -u tools/include/uapi/drm/drm.h include/uapi/drm/drm.h
Now 'perf trace' and other code that might use the
tools/perf/trace/beauty autogenerated tables will be able to translate
this new ioctl code into a string:
$ tools/perf/trace/beauty/drm_ioctl.sh > before
$ cp include/uapi/drm/drm.h tools/include/uapi/drm/drm.h

To pick the changes from:

cab56d3484d4 ("x86/entry: Remove ABI prefixes from functions in syscall tables")
27dd84fafcd5 ("x86/entry/64: Use syscall wrappers for x32_rt_sigreturn")
Addressing this tools/perf build warning:
Warning: Kernel ABI header at 'tools/perf/arch/x86/entry/syscalls/syscall_64.tbl' differs from latest version at 'arch/x86/entry/syscalls/syscall_64.tbl'
diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl
That didn't result in any tooling changes, as what is extracted are just
the first two columns, and these patches touched only the third.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
To pick up the changes in these csets:
295bcca84916 ("linux/bits.h: add compile time sanity check of GENMASK inputs")
3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO")
To address this tools/perf build warning:
Warning: Kernel ABI header at 'tools/include/linux/bits.h' differs from latest version at 'include/linux/bits.h'
diff -u tools/include/linux/bits.h include/linux/bits.h
This clashes with usage of userspace's static_assert(), that, at least
on glibc, is guarded by a ifnded/endif pair, do the same to our copy of
build_bug.h and avoid that diff in check_headers.sh so that we continue
checking for drifts with the kernel sources master copy.
This will all be tested with the set of build containers that includes
uCLibc, musl libc, lots of glibc versions in lots of distros and cross
build environments.
The tools/objtool, tools/bpf, etc were tested as well.
