| |
From: Thomas Richter <richter@de.ibm.com>
perf test '89: probe libc's inet_pton & backtrace it with ping' fails on x86. Debugging revealed a changed stack trace for the ping command using probes:
ping 35729 [002] 8006.365063: probe_libc:inet_pton: (3ff9603e7c0) 12be50 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6) 4fca main+0x139b (/usr/bin/ping)
The line getaddrinfo.... in the call stack is gone. It was introduced with glibc version 2.36.8 released with Fedora 37.
Output before on x86 # ./perf test 89 89: probe libc's inet_pton & backtrace it with ping : FAILED! #
Output after on x86: # ./perf test 89 89: probe libc's inet_pton & backtrace it with ping : Ok #
