This test currently fails because the regular expressions for
matching the output of perf script do not consider the symbol
offsets to be part of the output.
The symbol offsets are seen because of the default behaviour
introduced by commit 4140d2ea74b3 ("perf script: Show symbol
offsets by default").
Before applying this patch:
# perf test -v "probe libc's inet_pton & backtrace it with ping"
62: probe libc's inet_pton & backtrace it with ping :
--- start ---
test child forked, pid 30389
ping 30406 [002] 307144.280983: probe_libc:inet_pton: (7f4117adf220)
7f4117adf220 __GI___inet_pton+0x0 (/usr/lib64/libc-2.25.so)
FAIL: expected backtrace entry 1 ".*inet_pton[[:space:]]\(/usr/lib64/libc-2.25.so|inlined\)$" got "7f4117adf220 __GI___inet_pton+0x0 (/usr/lib64/libc-2.25.so)"
test child finished with -1
---- end ----

After applying this patch:
# perf test -v "probe libc's inet_pton & backtrace it with ping"

This patch fails on s390. I used 4.17.0rc5 + fedora 27 and I get this output:
[root@p23lp27 perf]# ./perf test 59
59: probe libc's inet_pton & backtrace it with ping : Ok
[root@p23lp27 linux]# cd ~/linux; patch -p1 < ../inet_pton1
(Stripping trailing CRs from patch; use --binary to disable.)

[root@p23lp27 perf]# ./perf test 59
59: probe libc's inet_pton & backtrace it with ping : FAILED!
[root@p23lp27 perf]#
Debugging revealed this line as cause of failure:
FAIL: expected backtrace entry 2 "gaih_inet.*\+0x[[:xdigit:]]+[[:space:]]\(/usr/lib64/libc-2.26.so|inlined\)$" got "fdcb1 gaih_inet.constprop.7 (/usr/lib64/libc-2.26.so)"
Here is the output of the trace file
[root@p23lp27 perf]# perf script

Hope this helps

Can you please apply these two patches as well and then re-test?

Actually I'll fold this patch into the patch that made this test break,
so that we keep the tree bisectable wrt that specific 'perf test' entry.

Looks like perf failed to resolve the symbol's name for the last entry
in the callchain. I did not consider this case. So, if this happens, we
would be better off using the original regex for the last line:
expected[3]=".*\(.*/bin/ping.*\)$"

So it is there, but I don't have debuginfo for ping, lets see if I add
it...
[root@seventh perf]# rpm -qf `which ping`
iputils-20161105-7.fc27.x86_64
[root@seventh perf]#
[root@seventh perf]# dnf debuginfo-install iputils
[root@seventh perf]# perf script
ping 29170 [001] 14644.810782: probe_libc:inet_pton: (7f0bac71be40)
7f0bac71be40 __GI___inet_pton+0x0 (/usr/lib64/libc-2.26.so)

5585e10adf40 main+0x880 (/usr/bin/ping)
[root@seventh perf]#
So we need to check if debuginfo is available, and if so, expect it to
resolve that entry to main, if not, expect it to _not_ resolve and have
[unknown] instead...

But tis is not related to your recent patches, so I'm folding this last
one with the one adding the offsets and go on from there...
