Description Mads Kiilerich 2011-09-17 12:31:32 UTC

# restorecon -rvn /dev
restorecon reset /dev/pts/ptmx context system_u:object_r:devpts_t:s0->system_u:object_r:ptmx_t:s0

I would expect the file to be labeled correctly in the first place.

Comment 1 Mads Kiilerich 2011-09-21 14:51:06 UTC

this has _not_ been fixed by

Comment 2 Daniel Walsh 2011-09-21 14:57:48 UTC

Yes we know, we are not sure what is causing it but it does not seem to cause any problems.

I am not even sure what the difference between the two files is.

 ls -lZ /dev/ptmx /dev/pts/ptmx 
crw-rw-rw-. root tty  system_u:object_r:ptmx_t:s0      /dev/ptmx
c---------. root root system_u:object_r:devpts_t:s0    /dev/pts/ptmx


Maybe we should just change the label of /dev/pts/ptmx to devpts_t and forget about it.  It does not look like this device path is used.

Comment 3 Mads Kiilerich 2011-09-21 15:10:40 UTC

$0.05 of observations and opinions:

crw-rw-rw-. 1 root tty  5, 2 Sep 21 11:04 /dev/ptmx
c---------. 1 root root 5, 2 Sep 21 10:44 /dev/pts/ptmx

- so it is the same device but /dev/ptmx can actually be used and follows the local OS policy for unix access control. I guess devpts is for "internal" low-level use only, so it could make sense that they have different labels.

Comment 4 Daniel Walsh 2011-09-21 15:25:51 UTC

Ok I am just going to remove the label so that the tools will not complain, and see if it ends up causing any problems, which it has not so far.

Fixed in selinux-policy-3.10.0-33.fc16
