由 Jiri Olsa 提交于
Adding automated test for breakpoint event signal handler checking if it's executed properly. The test is related to the proper handling of the RF EFLAGS bit on x86_64, but it's generic for all archs. First we check the signal handler is properly called and that the following debug exception return to user space wouldn't trigger recursive breakpoint. This is related to x86_64 RF EFLAGS bit being managed in a wrong way. Second we check that we can set breakpoint in signal handler, which is not possible on x86_64 if the signal handler is executed with RF EFLAG set. This test is inpired by overflow tests done by Vince Weaver. Signed-off-by: NJiri Olsa <jolsa@redhat.com> Cc: "H.

Jiri Olsa triggers the following build error: SUBDIR ../lib/lk/ CC debugfs.o In file included from /usr/include/errno.h:29:0, from debugfs.c:1: /usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp] This is because enabling buffer overflow checks through _FORTIFY_SOURCE require compiler optimizations to be enabled too. However, those are not. Enable them by simply copying the perf optimization level. It can be expanded later if we want to support debug builds, etc. Signed-off-by: NBorislav Petkov <bp@suse.de> Reported-by: NJiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/1362338733-8718-1-git-send-email-bp@alien8.deSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

page-flags.c had some older version of debugfs_mount copied from perf so convert it to using the version in the tools library.

This introduces the tools/lib/lk library, that will gradually have the routines that now are used in tools/perf/ and other tools and that can be shared. Start by carving out debugfs routines for general use.

Make attr script to check for 'cpu' when testing event properties. This will allow us to check the '-C X' option for both record and stat commands.
