What are the differences between `-f` and `-A` of `ss`?
What are the differences between -f and -A of ss?
Which of -f and -A is related to -t, -u, -4, -6, -w, -x?
Does -A inet,packet imply -A tcp,udp,raw?
I know a few socket concepts, but can't figure out the terminology in the manpage.
Thanks.
-f
Display sockets of type FAMILY. Currently the following families are
supported: unix, inet, inet6, link, netlink.
-A Query
List of socket tables to dump, separated by commas. The following
identifiers are understood: all, inet, tcp, udp, raw, unix, packet,
netlink, unix_dgram, unix_stream, unix_seqpacket, packet_raw,
packet_dgram.

-4, -6, -x - as per man page.
-t, -u, -w all correspond to socket tables.
The table inet implies all of tcp, udp, raw, and presumably also dccp and sctp. I assume all is synthetic at some level, so I assume inet is similar.
When overlapping tables are specified (e.g. -A tcp,inet), ss does not show duplicates.
I do not think that -A packet and -A raw overlap, BUT...
I do not know what the socket tables packet, packet_raw, and packet_dgram are doing! When I request these, I see nothing. But when I request -0 aka -f link, I see sockets which are shown with the "netid"s p_raw and p_dgram. Weird!
The name "socket tables" is talking about the native tables inside the kernel. So it is very efficient to list exactly tcp sockets for example, we just list the entire table. You can see old plain-text /proc interfaces for these tables listed in the old man netstat.
Other filters might print much less compared to the size of the table they need to scan, in this sense they might be less efficient. But, I would not worry about it.
