In debian/ubuntu, libc.so is located at a different place, /lib/x86_64-linux-gnu/libc-2.23.so, so it outputs like this when testing: PING ::1(::1) 56 data bytes 64 bytes from ::1: icmp_seq=1 ttl=64 time=0.040 ms --- ::1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.040/0.040/0.040/0.000 ms 0.000 probe_libc:inet_pton:(7f0e2db741c0)) __GI___inet_pton (/lib/x86_64-linux-gnu/libc-2.23.so) getaddrinfo (/lib/x86_64-linux-gnu/libc-2.23.so) [0xffffa9d40f34ff4d] (/bin/ping) Fix up the libc path to make sure this test works in more OSes. Committer testing: When this test fails one can use 'perf test -v', i.e. in verbose mode, where it'll show the expected backtrace, so, after applying this test: On Fedora 26: # perf test -v ping 62: probe libc's inet_pton & backtrace it with ping : --- start --- test child forked, pid 23322 PING ::1(::1) 56 data bytes 64 bytes from ::1: icmp_seq=1 ttl=64 time=0.058 ms --- ::1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.058/0.058/0.058/0.000 ms 0.000 probe_libc:inet_pton:(7fe344310d80)) __GI___inet_pton (/usr/lib64/libc-2.25.so) getaddrinfo (/usr/lib64/libc-2.25.so) _init (/usr/bin/ping) test child finished with 0 ---- end ---- probe libc's inet_pton & backtrace it with ping: Ok # Signed-off-by: Li Zhijian <lizhijian@cn.fujitsu.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Kim Phillips <kim.phillips@arm.com> Cc: Li Zhijian <lizhijian@cn.fujitsu.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Philip Li <philip.li@intel.com> Link: http://lkml.kernel.org/r/1508315649-18836-1-git-send-email-lizhijian@cn.fujitsu.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
