bpf, s390: fix build for libbpf and selftest suite

2017-08-04T18:18:01+00:00

The BPF feature test as well as libbpf is missing the __NR_bpf
define for s390 and currently refuses to compile (selftest suite
depends on libbpf as well). Similar issue was fixed some time
ago via b0c47807d31d ("bpf: Add sparc support to tools and
samples."), just do the same and add definitions.

tools build: Add test for setns()

2017-07-19T02:14:08+00:00

And provide an alternative implementation to keep perf building on older
distros as we're about to add initial support for namespaces.

kbuild: simplify silent build (-s) detection

2017-06-06T00:01:12+00:00

This allows to detect -s (--silent) option without checking GNU Make
version.

As commit e36aaea28972 ("kbuild: Fix silent builds with make-4")
pointed out, GNU Make 4.x changed the way/order it presents the
command line options into MAKEFLAGS.

In Make 3.8x, 's' is always the first in a group of short options.
The group may be prefixed with '-' in some cases.

In Make 4.x, 's' is always the last in a group of short options.

As commit e6ac89fabd03 ("kbuild: Correctly deal with make options
which contain an 's'") addressed, we also need to deal with long
options that contain 's', like --warn-undefined-variables.

Test cases:

[1] command line input:    make --silent
     -> MAKEFLAGS for Make 3.8x:    s
     -> MAKEFLAGS for Make 4.x :    s

[2] command line input:    make -srR
     -> MAKEFLAGS for Make 3.8x:    sRr
     -> MAKEFLAGS for Make 4.x :    rRs

[3] command line input:    make -s -rR --warn-undefined-variables
     -> MAKEFLAGS for Make 3.8x:    --warn-undefined-variables -sRr
     -> MAKEFLAGS for Make 4.x :    rRs --warn-undefined-variables

My idea to cater to all the cases more easily is to filter out long
options (--%), then search 's' with $(findstring ...).  This way will
be more future-proof even if future versions of Make put 's' in the
middle of the group.

bpf: Add strict alignment flag for BPF_PROG_LOAD.

2017-05-11T18:19:00+00:00

Add a new field, "prog_flags", and an initial flag value
BPF_F_STRICT_ALIGNMENT.

When set, the verifier will enforce strict pointer alignment
regardless of the setting of CONFIG_EFFICIENT_UNALIGNED_ACCESS.

The verifier, in this mode, will also use a fixed value of "2" in
place of NET_IP_ALIGN.

This facilitates test cases that will exercise and validate this part
of the verifier even when run on architectures where alignment doesn't
matter.

tools build: Fixup sched_getcpu feature test

2017-05-04T13:30:40+00:00

We have tools/build/feature/test-all.c to speed up feature testing,
doing all tests at once, but then all tests in this file should normally
pass.

That is not the case with the sched-getcpu one, that wasn't passing when
included from test-all.c because it needs to have _GNU_SOURCE defined
before including sched.h, but _GNU_SOURCE is defined by a header
included from another feature test included earlier in test-all.d,
test-libpython.c, resulting in:

  $ cat /tmp/build/perf/feature/test-all.make.output
  In file included from test-all.c:121:0:
  test-sched_getcpu.c:1:0: error: "_GNU_SOURCE" redefined [-Werror]
   #define _GNU_SOURCE

  In file included from /usr/include/python2.7/pyconfig.h:6:0,
                   from /usr/include/python2.7/Python.h:8,
                   from test-libpython.c:1,
                   from test-all.c:13:
  /usr/include/python2.7/pyconfig-64.h:1177:0: note: this is the location of the previous definition
   #define _GNU_SOURCE 1

  cc1: all warnings being treated as errors

Which would trigger testing the tests individually, when that
_GNU_SOURCE redefinition would not take place, and the whole process
would continue, just slower... Fix it.
