 |
|
Hi,
I have issues with incorrectly labeled files and directories in /var/run. Take /var/run/udev for example:
| Code: | ls -dZ /var/run/udev/
system_u:object_r:tmpfs_t /var/run/udev/ |
even though it is supposed to be system_u:object_r:udev_var_run_t and correct file context rules are installed:
| Code: | semanage fcontext -l | grep /var/run/udev
/var/run/udev(/.*)? all files system_u:object_r:udev_var_run_t
/var/run/udev-configure-printer(/.*)? all files system_u:object_r:cupsd_config_var_run_t
/var/run/udev/data(/.*)? all files system_u:object_r:udev_tbl_t
/var/run/udev/rules\.d(/.*)? all files system_u:object_r:udev_rules_t |
I suspect that this is because /var/run is a symlink to /run. I had found some mention about it here, but that post is fairly old. Does anybody know how to solve this problem? Thanks |

Hmm, restorecon -r /var/run fixed it, does anybody knows why running rlpkg didn't worked?
EDIT:
Bit of an update, hope it will help somebody:
rlpkg doesn't work because it deals with package owned files, while /var/run/* is runtime created. For the same reason restorecon -r /var/run doesn't persist reboot. Problem is caused by context of process that creates /var/run/udev which is not initrc_t (/etc/init.d/udev) but probably /lib64/rc/bin/checkpath. When I delete /var/run/udev at runtime and issue /etc/init.d/udev restart, /var/run/udev gets created with proper context. This was discussed, again, in the past. |
