That's wrong and can lead to unresolved mmaps in report output for 32bit binaries on 64bit server, like in this example on x86_64 server: $ cat ex.c int main(int argc, char **argv) { while (1) {} } $ gcc -o ex -m32 ex.c $ perf record ./ex ^C[ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.371 MB perf.data (9322 samples) ] Before: $ perf report --stdio SNIP # Overhead Command Shared Object Symbol # ........ ....... ................ ...................... # 100.00% ex [unknown] [.] 0x00000000080483de 0.00% ex [unknown] [.] 0x00000000f76dba4f 0.00% ex [unknown] [.] 0x00000000f76e4c11 0.00% ex [unknown] [.] 0x00000000f76daa30 After: $ perf report --stdio SNIP # Overhead Command Shared Object Symbol # ........ ....... ............. ............... # 100.00% ex ex [.] main 0.00% ex ld-2.24.so [.] _dl_start 0.00% ex ld-2.24.so [.] do_lookup_x 0.00% ex ld-2.24.so [.] _start The fix is not to fail, just warn if there's not unwind support compiled in.

| | * perf evsel: Set attr.exclude_kernel when probing max attr.precise_ipArnaldo Carvalho de Melo2017-07-041-0/+1

The increase in the paranoid level in commit 0161028b7c8a ("perf/core: Change the default paranoia level to 2") broke this, fix it by excluding kernel samples when probing. Before: $ perf record usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.018 MB perf.data (6 samples) ] $ perf evlist -v cycles:u: sample_freq: 4000, sample_type: IP|TID|TIME|PERIOD, exclude_kernel: 1 After: $ perf record usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.018 MB perf.data (8 samples) ] $ perf evlist -v cycles:ppp: sample_freq: 4000, sample_type: IP|TID|TIME|PERIOD, exclude_kernel: 1, precise_ip: 3 ^^^^^^^^^^^^^ ^^^^^^^^^^^^^ ^^^^^^^^^^^^^ $ To further clarify: we always set .exclude_kernel when non !CAP_SYS_ADMIN users profile, its just on the attr.precise_ip probing that we weren't doing so, fix it.

It's just a normal jump to an address inside the function. Objtool thought it was a sibling call because the instruction's jump_dest wasn't initialized because the function was supposed to be ignored due to its use of sync_core(). Objtool ended up validating the function instead of ignoring it because it didn't properly recognize a sibling call to the function. So fix the sibling call logic. Also add a warning to catch ignored functions being validated so we'll get a more useful error message next time.

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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Those executables end up in the test's cwd, but that cwd is MNT_DETACHed. The core namespace code considers MNT_DETACHed trees to belong to no mount namespace at all and, in general, MNT_DETACHed trees are only barely function. This interacted with commit 380cf5ba6b0a ("fs: Treat foreign mounts as nosuid") to cause all MNT_DETACHed trees to act as though they're nosuid, breaking the test. Fix it by just not detaching the tree. It's still in a private mount namespace and is therefore still invisible to the rest of the system (except via /proc, and the same nosuid logic will protect all other programs on the system from believing in test_execve's setuid bits). While we're at it, fix some blatant whitespace problems.
