This allows net-yy-unix invocation without arguments.
* tests/net-yy-unix.c (TEST_SOCKET): New macro.
(void): Use it instead of av[1].
* tests/net-yy-unix.test: Do not specify arguments for the test
executable.
Automatically convert tests to use TAIL_ALLOC_OBJECT_CONST_PTR macro
with the following sed expression:
sed -ri \
's/^([[:space:]]*)(([^*]+[[:alnum:]_])( \*)?) *\*( *const )?([^ =]+) = tail_alloc\(sizeof\((\2|\*\6)\)\);/\1TAIL_ALLOC_OBJECT_CONST_PTR(\2, \6);/' \
tests/*.c
* net.c (decode_sockname): Print both user and kernel address lengths
when the value changes.
* tests/net-y-unix.c (main): Update expected output.
* tests/net-yy-unix.c (main): Likewise.
* tests/net.expected: Likewise.
As these constants have the same value 1, let's use and print only one
of them, e.g. AF_UNIX.
* xlat/addrfams.in (AF_LOCAL): Remove.
* tests/net-accept-connect.c (main): Replace AF_LOCAL with AF_UNIX.
* tests/net-y-unix.c: Likewise.
* tests/net-yy-unix.c: Likewise.
* tests/netlink_unix_diag.c: Likewise.
AF_* constants appear to be more standardized, and in practice there's
always a one to one relationship between AF_* and PF_*, so let's
use AF_* instead of PF_*.
* xlat/domains.in: Remove.
* net.c: Do not define PF_UNSPEC. Stop including "xlat/domains.h".
Replace PF_* with AF_*. Replace domains with addrfams.
* tests/inet-cmsg.c: Replace PF_INET with AF_INET.
* tests/net-yy-inet.c: Likewise.
* tests/netlink_inet_diag.c: Likewise.
* tests/net-accept-connect.c: Replace PF_LOCAL with AF_LOCAL.
* tests/net-y-unix.c: Likewise.
* tests/net-yy-unix.c: Likewise.
* tests/netlink_unix_diag.c: Likewise.
* tests/net.expected: Replace PF_ with AF_.
As -yy parser, compared to -y, needs to do at least 5 extra syscalls
(getxattr, socket, sendmsg, recvmsg, close) to print socket details,
caching results of netlink conversations between strace and kernel
noticeably reduces amount of system time spent by strace.
The caching is safe since sockets do not change their addresses after
successful bind or connect syscall.
* defs.h (string_quote, print_sockaddr_by_inode_cached): New prototypes.
* socketutils.c (cache_entry): New type.
(CACHE_SIZE, CACHE_MASK): New macros.
(cache): New static array.
(cache_and_print_inode_details): New static function.
(print_sockaddr_by_inode_cached): New function.
(inet_parse_response, unix_parse_response): Use
cache_and_print_inode_details.
* util.c (printfd): Use string_quote and print_sockaddr_by_inode_cached.
(string_quote): Remove static qualifier.
* NEWS: Mention this improvement.
* tests/unix-yy.c (main): Update.
Unlike the former test that was based on match_awk,
the new one uses match_diff and does more rigorous testing.
* tests/net-yy-unix.c: New file.
* tests/net-yy-unix.test: New test.
* tests/unix-yy.test: Remove.
* tests/unix-yy-accept.awk: Remove.
* tests/unix-yy-connect.awk: Remove.
* tests/.gitignore: Add net-yy-unix.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(TESTS): Replace unix-yy.test with net-yy-unix.test.
(EXTRA_DIST): Remove unix-yy-accept.awk and unix-yy-connect.awk.
