perf trace augmented_syscalls: Augment bind's 'myaddr' sockaddr arg
One more, to reuse the augmented_sockaddr_syscall_enter() macro introduced from the augmentation of connect's sockaddr arg, also to get a subset of the struct arg augmentations done using the manual method, before switching to something automatic, using tracefs's format file or, even better, BTF containing the syscall args structs. # perf trace -e tools/perf/examples/bpf/augmented_syscalls.c 0.000 sshd/11479 bind(fd: 3<socket:[170336]>, umyaddr: { .family: NETLINK }, addrlen: 12) 1.752 sshd/11479 bind(fd: 3<socket:[170336]>, umyaddr: { .family: INET, port: 22, addr: 0.0.0.0 }, addrlen: 16) 1.924 sshd/11479 bind(fd: 4<socket:[170338]>, umyaddr: { .family: INET6, port: 22, addr: :: }, addrlen: 28) ^C# Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-a2drqpahpmc7uwb3n3gj2plu@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
