* netlink_sock_diag.c (unix_diag_msg_nla_decoders): New array.
(decode_unix_diag_msg): Use it.
* linux/unix_diag.h (unix_diag_vfs, unix_diag_rqlen): New structures.
This change extends -yy option to handle unix domain sockets:
their peer addresses will be printed, similar to inet sockets.
For a listening socket, its socket inode and socket path are printed.
For an accepted socket, its socket inode, the peer inode, and the
socket path are printed.
For a client socket, its socket inode and the peer inode are printed.
An example of a server side communication using netcat:
$ ./strace -yy -e network nc -l -U /tmp/example.sock
socket(PF_LOCAL, SOCK_STREAM, 0) = 3
setsockopt(3<UNIX:[14728348]>, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(3<UNIX:[14728348]>, {sa_family=AF_LOCAL, sun_path="/tmp/example.sock"}, 19) = 0
listen(3<UNIX:[14728348,"/tmp/example.sock"]>, 10) = 0
accept(3<UNIX:[14728348,"/tmp/example.sock"]>, {sa_family=AF_LOCAL, NULL}, [2]) = 4<UNIX:[14727246->14727245,"/tmp/example.sock"]>
recvfrom(4<UNIX:[14727246->14727245,"/tmp/example.sock"]>, "INPUT\n", 8192, 0, NULL, NULL) = 6
INPUT
An example of a client side communication using netcat:
$ ./strace -yy -e network nc -U /tmp/example.sock
socket(PF_LOCAL, SOCK_STREAM, 0) = 3
connect(3<UNIX:[14727245]>, {sa_family=AF_LOCAL, sun_path="/tmp/example.sock"}, 19) = 0
getsockopt(3<UNIX:[14727245]>, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
INPUT
...
sendto(3<UNIX:[14727245->14727246]>, "INPUT\n", 6, 0, NULL, 0) = 6
* linux/unix_diag.h: New file.
* socketutils.c (send_query): Rename to inet_send_query.
(parse_response): Rename to inet_parse_response.
(unix_print, unix_send_query, unix_parse_response): New functions.
(receive_responses): Add a new argument named parser: a function for
handling protocol specific data parts of diag messages.
(print_sockaddr_by_inode): Call unix_print.
Replace NETLINK_INET_DIAG with NETLINK_SOCK_DIAG, they are equal
but NETLINK_SOCK_DIAG looks more generic.
