| |
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
