Hy!
While diagnosing some network spamming apparently caused by Pidgin
https://forums.opensuse.org/showthread.php/575344-New-(-)-MDNS-spam-How-to-stop
I stumbled upon a non-functional ss on my TW (I have other TW installs and Leap 15.4 where ss is working, so apparently related to hardware?).
When starting ss in a console I simply get the message “Killed” and no further output, starting ss again leaves the console unresponsive.
On first ss I get in dmesg

Not necessarily. Stack trace looks entirely software and other systems have different kernel or do not have the same conditions.

It sounds like ss triggers kernel in sending information about raw sockets and this function misbheaves.
What is output of “cat /proc/net/raw”?
Do any of “ss -t” or “ss -u” or “ss -x” work?
Thanks for reply, I have:
cat /proc/net/raw
sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode ref pointer drops
Option for ss works on first try (-t -u and -x) and following tries! But after “ss only”: “Killed” and then unresponsive console.
…found a second TW install with the same problem, ss results in “Killed” and in dmesg

Option for ss works on first try (-t -u and -x) and following tries!
You should open bug report on bugzilla.opensuse.org.

various. but only intel insider…
…with kernel 6.0 (or whatever fixed it…) ss apparently works without options here.
