perf test record+probe_libc_inet_pton: Fix call chain match on s390
With Fedora 38 the perf test 86 probe libc's inet_pton fails on s390. The call chain of the ping command changed. The functions text_to_binary_address() and gaih_inet() do not show up in the call chain anymore. Output before: # ./perf test -v 86 86: probe libc's inet_pton & backtrace it with ping : --- start --- test child forked, pid 541050 fgrep: warning: fgrep is obsolescent; using grep -F fgrep: warning: fgrep is obsolescent; using grep -F BFD: DWARF error: could not find variable specification at offset 0x22011 ... ping 541078 [002] 348826.679581: probe_libc:inet_pton_1: (3ffad84b940) 14b940 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6) 10e9c3 __GI_getaddrinfo+0xeb3 (inlined) 4397 main+0x737 (/usr/bin/ping) FAIL: expected backtrace entry "gaih_inet.*\+0x[[:xdigit:]]\ +[[:space:]]\(/usr/lib64/libc.so.6|inlined\)$" got "4397 main+0x737 (/usr/bin/ping)" test child finished with -1 ---- end ---- probe libc's inet_pton & backtrace it with ping: FAILED! # Output after: # ./perf test -v 86 86: probe libc's inet_pton & backtrace it with ping : --- start --- test child forked, pid 541098 fgrep: warning: fgrep is obsolescent; using grep -F fgrep: warning: fgrep is obsolescent; using grep -F BFD: DWARF error: could not find variable specification at offset 0x309d1 ... ping 541126 [006] 349309.099067: probe_libc:inet_pton_1: (3ffb7f4b940) 14b940 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6) 10e9c3 __GI_getaddrinfo+0xeb3 (inlined) 4397 main+0x737 (/usr/bin/ping) test child finished with 0 ---- end ---- probe libc's inet_pton & backtrace it with ping: Ok # Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Cc: Heiko Carstens <hca@linux.ibm.com> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: https://lore.kernel.org/r/20230503081134.3372415-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
