Arnaldo Carvalho de Melo d5a7e6613b perf trace augmented_syscalls: Augment connect's 'sockaddr' arg ... As the first example of augmenting something other than a 'filename', augment the 'struct sockaddr' argument for the 'connect' syscall: # perf trace -e tools/perf/examples/bpf/augmented_syscalls.c ssh -6 fedorapeople.org 0.000 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 0.042 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 1.329 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 1.362 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 1.458 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 1.478 ssh/29669 connect(fd: 3, uservaddr: { .family: LOCAL, path: /var/run/nscd/socket }, addrlen: 110) 1.683 ssh/29669 connect(fd: 3<socket:[125942]>, uservaddr: { .family: INET, port: 53, addr: 192.168.43.1 }, addrlen: 16) 4.710 ssh/29669 connect(fd: 3<socket:[125942]>, uservaddr: { .family: INET6, port: 22, addr: 2610:28:3090:3001:5054:ff:fea7:9474 }, addrlen: 28) root@fedorapeople.org: Permission denied (publickey). # This is still just augmenting the syscalls:sys_enter_connect part, later we'll wire this up to augment the enter+exit combo, like in the tradicional 'perf trace' and 'strace' outputs.
