Bug 999594

Description of problem:
We'd like to change the default error log file location in MariaDB to a location that would more correspond with the package name (while systemd unit file should be renamed as well). More info about this step in bug #999589

The current log file location is /var/log/mysqld.log

The new log file location will be
/var/log/mariadb/mariadb.log

So basically we need /var/log/mariadb and /var/log/mariadb/mariadb.log (maybe everything /var/log/mariadb(.*)$ ) to have SELinux context the same as /var/log/mysqld.log.

When doing this manually, there were still some issues:
# ls -dZ /var/log/mariadb /var/log/mariadb/mariadb.log
drwxr-x---. mysql mysql system_u:object_r:mysqld_log_t:s0 /var/log/mariadb
-rw-r-----. mysql mysql system_u:object_r:mysqld_log_t:s0 /var/log/mariadb/mariadb.log

/var/log/messages says:
Aug 21 18:17:57 dhcp-25-53 kernel: [1187569.555129] type=1400 audit(1377101877.904:145524): avc:  denied  { search } for  pid=7539 comm="mysqld_safe" name="mariadb" dev="dm-1" ino=629757 scontext=system_u:system_r:mysqld_safe_t:s0 tcontext=system_u:object_r:mysqld_log_t:s0 tclass=dir


Version-Release number of selected component (if applicable):
# rpm -q selinux-policy
selinux-policy-3.12.1-69.fc19.noarch

How reproducible:
every-time

Steps to Reproduce:
1. change log-errors to /var/log/mariadb/mariadb.log in /etc/my.cnf
2. mkdir /var/log/mariadb
3. touch /var/log/mariadb/mariadb.log
4. chown -R mysql:mysql /var/log/mariadb
5. semanage fcontext -a -e /var/log/mysqld.log /var/log/mariadb
6. restorecon -r /var/log/mariadb
7. systemctl start mysqld

Actual results:
AVC denials
mysqld doesn't start

Expected results:
no AVC denials
mysqld starts
