11656206ff Fix corner cases of rt_sigpending syscall decoder 
* signal (print_sigset_addr_len_limit): New function, cloned from
print_sigset_addr_len with added minimal length argument.
Treat length less than minimal length or greater than NSIG/8 as invalid.
Do not align length to 4-byte boundary.  Align destination buffer
to 4-byte boundary and initialize it with zeroes so that subsequent
call to sprintsigmask_n will not access uninitialized data.
(print_sigset_addr_len): Turn into a wrapper around
print_sigset_addr_len_limit with current_wordsize
as a minimal length argument.
(SYS_FUNC(rt_sigpending)): Call print_sigset_addr_len_limit
instead of print_sigset_addr_len with 1 as a minimal length argument.

10c61e3b22 Change unix_diag requests back to use full dump instead of exact match 
Unfortunately, 64-bit linux kernel has a bug in matching inode numbers
greater than INT_MAX, so unix_diag exact match is not reliable.

This partially reverts commit 69bfc89770.

* socketutils.c (unix_send_query): Add NLM_F_DUMP to nlmsg_flags,
remove initialization of udiag_cookie.
* tests/netlink_unix_diag.c (send_query): Remove "inode" argument,
add NLM_F_DUMP to nlmsg_flags, remove initialization of udiag_ino
and udiag_cookie.
(check_responses): Remove "inode" argument and its use.
(main): Remove invocation of inode_of_sockfd and passing of listening
socket inode to send_query and check_responses.
