Description MASAO TAKAHASHI 2005-01-11 01:01:34 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; ja-JP; rv:1.7.5)
Gecko/20041108 Firefox/1.0

Description of problem:
The dri device "card0" has no other's access rights as follows.
crw-rw---- 1 root root 226, 0 Jan 11 09:12 card0
And OpenOffice1.1.3 programs open the device "card0", then
fail to open "card0".
This causes segmentation error and OpenOffice cannot start.

On the kernel-2.6.10-1.1053_FC4, "/dev/dri/card0" has access rights
as follows.
crw-rw-rw- 1 root root 226, 0 Jan 11 09:30 card0
So, OpenOffice1.1.3  can start normally.
I attached strace log.

Version-Release number of selected component (if applicable):
kernel-2.6.10-1.1076_FC4

How reproducible:
Always

Steps to Reproduce:
1.start kernel-2.6.10-1.1076_FC4
2.start any OpenOffice1.1.3 Program
3.this symptom ocuured

Comment 2 MASAO TAKAHASHI 2005-01-11 02:50:09 UTC
New facts I find.
1. kernel-2.6.10-1.737_FC3 is OK.
2. Editing /etc/udev/permissions.d/50-udev.permissions 
   dri/*:root:root:0660 ---> dri/*:root:root:0666
   In this case, kernel-2.6.10-1.1076_FC4 is OK.
3. In kernel-2.6.10-1.737_FC3, even though not editing
    50-udev.permissions, the sypmtom does not occure.
 I don't know which has a problem kernel or OpenOffice.



Comment 3 Dave Jones 2005-01-11 03:17:49 UTC
when you get the segmentation fault, is there a kernel panic in the
output of 'dmesg' ?

660 is correct permissions for this devnode, as otherwise it would be
a security hole.


Comment 4 MASAO TAKAHASHI 2005-01-11 03:47:07 UTC
No, there is not a kernel panic.
