New kernel and netstat 'problem'
lo, anyone can confirm that netstat -p isn't working correctly on the new kernel? at least on 7.3. with 2.4.18 it doesn't work correctly: before: tcp 0 0 217.69.160.53:25 0.0.0.0:* LISTEN 27721/master after: tcp 0 0 217.69.160.53:25 0.0.0.0:* LISTEN 5877/ as you can see, the name of the process isn't displayed (but the pid, which is correct...) Regards, Sven

I can confirm the problem on suse 8.1. I've posted a bugreport (#25903). -- Dirk

I cannot confirm the same problem on k_psmp kernel ! The LISTEN and ESTABLISHED connections are ok.

I can confirm this for a stock 2.4.21-pre5 patched with 2.4.20-ow0 (openwall.com) and Alan Cox' ptrace patch (cset-1.1076.txt), as for a stock 2.4.20 patched ow0 + cset-1.1076. Btw. if you can confirm ps refuses to display /full/path/to/program for all child processes, then I suppose it's a side effect Alan's patch, which merely kicks 'kernel_tread' for call to 'arch_kernel_thread'.

yes, I can confirm this. /proc/<pid>/cmdline is simply empty for those programs, thats why netstat -p (or ps -ef for that matter) does no longer work. Pretty ugly bug :-( -- Dirk
