I'm guessing you passed IPPROTO_RAW (255) as the protocol to socket(). If you pass something
else (IPPROTO_ICMP for example) it won't work.
True. To support IPPROTO_ICMP it need enhancement. I thought start with
plain _RAW first and then extend to support _ICMP.
I thought raw in this case was SOCK_RAW as in the socket type.
Since the display is showing sockets in addition to IPPROTO_RAW:
$ ss -A raw
State Recv-Q Send-Q Local Address:Port Peer Address:Port
UNCONN 0 0 *%eth0:icmp *:*
It is going to be confusing if only ipproto-255 sockets can be killed.
OK, gimme some time to implement it. Hopefully on the weekend or monday.
Thanks a huge for feedback!
It may well be a ss bug / problem. As I mentioned I am always seeing 255 for the protocol which is odd since ss does a dump and takes the matches and invokes the kill. Thanks for taking the time to do the kill piece.
