Description jan vestby 2005-11-22 15:27:59 EST
Starting with nov 20 updates su does not work from xterm: 
[jan@hjemme ~]$ su - 
[jan@hjemme ~]$ 
stracing the operation terminates with: 
getuid32()                              = 500 
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfd1fa48) = -1 ENOTTY (Inappropriate 
ioctl for device) 
write(2, "standard in must be a tty\n", 26) = 26 
close(1)                                = 0 
munmap(0xf3d000, 9680)                  = 0 
exit_group(1)                           = ? 
Process 6642 detached 
(well, it's not a tty....) 
Outside x it works as expected 
How reproducible: allways 
Steps to Reproduce: 
1. open xterminal 
2. type su - 
Actual results: nothing 
Expected results: prompted for password 
Additional info: i386 platform (P4 CPU) 
Maybe this is intended ? 
Maybe there is something funny with the configuration of the machine ?

If you disable SELinux using 'setenforce 0', does the problem go away?
Comment 2 jan vestby 2005-11-22 18:01:52 EST
Yes. Then the problem goes away.

What does this say?:

rpm -q coreutils gnome-terminal selinux-policy-targeted selinux-policy-strict

I haven't been able to reproduce the problem here with Fedora Core 5test1.
Comment 4 jan vestby 2005-11-24 13:41:21 EST
$ rpm -q coreutils gnome-terminal selinux-policy-targeted 
package selinux-policy-strict is not installed 
Believe I have defaults for everything related to selinux, though there seem 
to be 2 targeted policies. Had not noticed this before. 
Strange thing: Rebooting after yesterdays (nov 23) update made the problem 
Comment 5 Tim Waugh 2005-11-24 18:10:44 EST
Okay, I suspect this was a bug in selinux-policy-targeted.  Please re-open if
you see this again.
