Description Ren-Bo Wang 2011-05-15 03:04:16 UTC
SELinux is preventing /usr/bin/updatedb from 'getattr' accesses on the directory /etc/NetworkManager/VPN.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that updatedb should be allowed getattr access on the VPN directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep updatedb /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-05-16 06:03:57 UTC
The directory is mislabeled.

# matchpathcon /etc/NetworkManager/VPN
/etc/NetworkManager/VPN	system_u:object_r:NetworkManager_etc_t:s0

Execute

# restorecon -R -v /etc/NetworkManager/VPN

Any idea how this got the bad label?

Comment 2 Miroslav Grepl 2011-05-16 08:54:16 UTC
Did you change the label for /etc/NetworkManager/VPN before an update?

Comment 6 Daniel Walsh 2011-05-17 08:18:22 UTC
postfix_virtual_t is a domain type, SELinux would not allow this label to be placed on a directory.  The only  way this label could get on the directory would be if the user did a chcon postfix_virtual_t /etc/NetworkManager/VPN in permissive mode.  Probably thinking this would allow postfix to read the content?


Ren-BO the restorecon should fix your problem.
