Description Hicham HAOUARI 2011-05-10 10:47:05 UTC
SELinux is preventing /bin/find from 'read' accesses on the directory /.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow find to have read access on the  directory
Then you need to change the label on /
Do
# semanage fcontext -a -t FILE_TYPE '/'
where FILE_TYPE is one of the following: device_t, locale_t, etc_t, proc_t, sysctl_crypto_t, prelink_cron_system_t, abrt_t, lib_t, root_t, usr_t, var_lib_t, device_t, etc_t, rpm_var_cache_t, textrel_shlib_t, rpm_var_lib_t, var_run_t, prelink_log_t, prelink_var_lib_t, bin_t, lib_t. 
Then execute: 
restorecon -v '/'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that find should be allowed read access on the  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 find /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 4 Miroslav Grepl 2011-05-16 20:11:24 UTC
Does it happen again?

Comment 5 Daniel Walsh 2011-05-17 08:04:25 UTC
This is probably a file system mounted under /mnt or /media  That is causing this.  The kernel reports "/" for the top Inode of any file system, not just the / for the root file system.  Most likely this can be ignored.  Miroslav we can probably just allow it.

> Does it happen again?

Yes, it happens all the time ( since some F-14 update that I am not sure of ). I don't have this issue on F-15.

Yes, it looks so.
