If given an invalid input file with -F flag, ss would crash.
Examples of invalid input are line to long, or null file.
Found by fuzzing with ASAN.

This allows the user to dump sockets with a given mark (via
"fwmark = 0x1234/0x1234" or "fwmark = 12345", etc.) , and to
display the socket marks of dumped sockets.
The relevant kernel commits are: d545caca827b ("net: inet: diag:
expose the socket mark to privileged processes.") and
- a52e95abf772 ("net: diag: allow socket bytecode filters to
match socket marks")

Add support for device names in the filter. Example:
root@kenny:~# ss -t 'sport == :22 && dev == red'
State Recv-Q Send-Q Local Address:Port Peer Address:Port
ESTAB 0 0 10.100.1.2%red:ssh 10.100.1.254:47814
ESTAB 0 0 2100:1::2%red:ssh 2100:1::64:49406
Since kernel does not support iface in the filter specifying a
device name means all filtering is done in userspace.
