Description Jens Petersen 2008-04-04 01:10:40 EDT
Description of problem:
scim-bridge seems to be causing avc denials whenever IM is started under GNOME:
ie when the first gtk application using scim-bridge is started, when Chinese
IMEs are installed.

How reproducible:
every time

Steps to Reproduce:
1. sudo yum groupinstall chinese-support
2. start SCIM with im-chooser
2. restart desktop
3. press F2 or open a gtk or gnome application like gedit or gnome-terminal
  
Actual results:
3. avc denial and setroubleshooting star icon in notification area.

Expected results:
3. no selinux warning
Comment 1 Jens Petersen 2008-04-04 01:53:02 EDT
Meant to add that this doesn't happen if scim-bridge is removed.

Comment 3 Daniel Walsh 2008-04-04 17:43:08 EDT
Looks like scim-bridge is leaking open file descriptors that ldconfig is looking at.

fcntl(fd, F_SETFD, FD_CLOEXEC)
Comment 4 Caius Chance 2008-04-06 23:37:50 EDT
The file was denied access has same context as normal:

$ ll -Z /usr/share/chewing/us_freq.dat 
-rw-r--r--  root root system_u:object_r:usr_t:s0      
/usr/share/chewing/us_freq.dat

$ ll -Z /usr/share/scim-python/helper/__init__.py
-rw-r--r--  root root system_u:object_r:usr_t:s0      
/usr/share/scim-python/helper/__init__.py
Comment 5 Daniel Walsh 2008-04-08 08:50:54 EDT
Yes but ldconfig would not try to access this file.  So the problem is someone
is leaking an open file descriptor to ldconfig, and SELinux checks the access on
the open file descriptor causing the AVC.
Comment 6 Jens Petersen 2008-04-11 01:47:49 EDT
Hmm seems fixed in rawhide anyway.  Thanks
