That helps us not to lose new protocol families when they are
introduced, replacing that hardcoded, dated family->string table.
To recap what this allows us to do:
# perf trace -e syscalls:sys_enter_socket/max-stack=10/ --filter=family==INET --max-events=1
0.000 fetchmail/41097 syscalls:sys_enter_socket(family: INET, type: DGRAM|CLOEXEC|NONBLOCK, protocol: IP)
__GI___socket (inlined)
reopen (/usr/lib64/libresolv-2.31.so)
send_dg (/usr/lib64/libresolv-2.31.so)
__res_context_send (/usr/lib64/libresolv-2.31.so)
__GI___res_context_query (inlined)
__GI___res_context_search (inlined)
_nss_dns_gethostbyname4_r (/usr/lib64/libnss_dns-2.31.so)
gaih_inet.constprop.0 (/usr/lib64/libc-2.31.so)
__GI_getaddrinfo (inlined)
[0x15cb2] (/usr/bin/fetchmail)
#
More work is still needed to allow for the more natura strace-like
syscall name usage instead of the trace event name:
# perf trace -e socket/max-stack=10,family==INET/ --max-events=1
I.e. to allow for modifiers to follow the syscall name and for logical
expressions to be accepted as filters to use with that syscall, be it as
trace event filters or BPF based ones.
Using -v we can see how the trace event filter is built:
# perf trace -v -e syscalls:sys_enter_socket/call-graph=dwarf/ --filter=family==INET --max-events=2
<SNIP>
New filter for syscalls:sys_enter_socket: (family==0x2) && (common_pid != 41384 && common_pid != 2836)
<SNIP>
$ tools/perf/trace/beauty/socket.sh | grep -w 2
