Description Adam Williamson 2013-03-19 23:57:20 UTC
Description of problem:
Occurs on boot of a Fedora 19 live image built from current repositories. SEalert claims the label is wrong, but if so, it's nothing I did.
SELinux is preventing /usr/bin/bash from 'execute_no_trans' accesses on the file /etc/NetworkManager/dispatcher.d/00-netreport.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/etc/NetworkManager/dispatcher.d/00-netreport default label should be NetworkManager_initrc_exec_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /etc/NetworkManager/dispatcher.d/00-netreport

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that bash should be allowed execute_no_trans access on the 00-netreport file 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 00-netreport /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Adam Williamson 2013-03-20 00:02:07 UTC
Final blocker: "In most cases, there must be no SELinux 'AVC: denied' messages or abrt crash notifications on initial boot and subsequent login"
