From 0f19a038afdc592176c9a302f0d08be6a68ad74a Mon Sep 17 00:00:00 2001 From: Thomas Richter Date: Wed, 14 Feb 2018 08:03:03 +0100 Subject: [PATCH] perf test: Fix test case inet_pton to accept inlines. Using Fedora 27 and latest Linux kernel the test case trace+probe_libc_inet_pton.sh fails again on s390. This time is the inlining of functions which does not match. After an update of the glibc (from 2.26-16 to 2.26-24) the output is different The expected output is: __inet_pton (/usr/lib64/libc-2.26.so) gaih_inet (inlined) .... The actual output is: 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.061/0.061/0.061/0.000 ms 0.000 probe_libc:inet_pton:(3ffb2140448)) __inet_pton (inlined) gaih_inet.constprop.7 (/usr/lib64/libc-2.26.so) ... Fix this by being less strict on 'inlined' verses library name and accept both Signed-off-by: Thomas Richter Cc: Heiko Carstens Cc: Hendrik Brueckner Cc: Martin Schwidefsky Link: http://lkml.kernel.org/r/20180214070303.55757-1-tmricht@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/tests/shell/trace+probe_libc_inet_pton.sh | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/tools/perf/tests/shell/trace+probe_libc_inet_pton.sh b/tools/perf/tests/shell/trace+probe_libc_inet_pton.sh index c446c894b297..8c4ab0b390c0 100755 --- a/tools/perf/tests/shell/trace+probe_libc_inet_pton.sh +++ b/tools/perf/tests/shell/trace+probe_libc_inet_pton.sh @@ -21,12 +21,12 @@ trace_libc_inet_pton_backtrace() { expected[3]=".*packets transmitted.*" expected[4]="rtt min.*" expected[5]="[0-9]+\.[0-9]+[[:space:]]+probe_libc:inet_pton:\([[:xdigit:]]+\)" - expected[6]=".*inet_pton[[:space:]]\($libc\)$" + expected[6]=".*inet_pton[[:space:]]\($libc|inlined\)$" case "$(uname -m)" in s390x) eventattr='call-graph=dwarf' - expected[7]="gaih_inet[[:space:]]\(inlined\)$" - expected[8]="__GI_getaddrinfo[[:space:]]\(inlined\)$" + expected[7]="gaih_inet.*[[:space:]]\($libc|inlined\)$" + expected[8]="__GI_getaddrinfo[[:space:]]\($libc|inlined\)$" expected[9]="main[[:space:]]\(.*/bin/ping.*\)$" expected[10]="__libc_start_main[[:space:]]\($libc\)$" expected[11]="_start[[:space:]]\(.*/bin/ping.*\)$" -- 2.11.0
