:*****  Plugin restorecon (93.9 confidence) suggests  *************************
:
:If you want to fix the label. 
:/var/webmin/miniserv.error default label should be var_log_t.
:Then you can run restorecon.
:Do
:# /sbin/restorecon -v /var/webmin/miniserv.error
:
:*****  Plugin catchall_labels (5.17 confidence) suggests  ********************
:
:If you want to allow hwclock to have append access on the miniserv.error file
:Then you need to change the label on /var/webmin/miniserv.error
:Do
:# semanage fcontext -a -t FILE_TYPE '/var/webmin/miniserv.error'
:where FILE_TYPE is one of the following: logfile, user_tmp_t, sosreport_tmp_t, abrt_var_cache_t, rpm_tmp_t, user_home_t, apmd_log_t, adjtime_t, logfile, hwclock_t, admin_home_t, user_cron_spool_t, puppet_tmp_t. 
:Then execute: 
:restorecon -v '/var/webmin/miniserv.error'
:
:
:*****  Plugin catchall (1.43 confidence) suggests  ***************************
:
:If you believe that hwclock should be allowed append access on the miniserv.error 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 hwclock /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
:
:*****  Plugin leaks (1.43 confidence) suggests  ******************************
:
:If you want to ignore hwclock trying to append access the miniserv.error file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:Do
:# grep /sbin/hwclock /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-03-09 10:59:53 UTC
You will need to fix labeling using the restorecon tool

$ restorecon -R -v /var/webmin

Comment 2 Daniel Walsh 2012-03-09 14:43:01 UTC
I just checked in a fix to make sure /var/webmin gets created with the correct label if a unconfined user creates it.
