Subject2.6.25.3: su gets stuck for root
Hi folks,

I haven't seen it mentioned here (hopefully I wasn't too blind to see):

If I run "su someuser" as root, then it gets stuck. No prompt. I cannot
interrupt it with ^C or ^Z either. /var/log/auth.log says:

May 13 08:06:41 pluto su[4193]: Successful su for root by harri
May 13 08:06:41 pluto su[4193]: + pts/3 harri:root
May 13 08:06:41 pluto su[4193]: pam_unix(su:session): session opened for user root by harri(uid=1000)

ps shows:

% ps -ef | grep pts/3
harri 4007 4006 0 07:58 pts/3 00:00:00 bash
root 4193 4007 0 08:06 pts/3 00:00:00 su
root 4194 4193 0 08:06 pts/3 00:00:00 bash
root 4209 4194 0 08:08 pts/3 00:00:00 su
root 4210 4209 0 08:08 pts/3 00:00:00 bash
root 4217 4210 0 08:08 pts/3 00:00:00 stty intr ^C

So obviously 'stty' is to blame here (called from root's .bashrc, as
it seems). But for 2.6.24.4 there is no such problem.


Maybe you could spread some light here?


Regards

Harri
