[DSE-Dev] Bug#724999: libsemanage-common: Missing configuration parameters makes semodule calls really slow

[Laurent Bigonville]

Package: libsemanage-common
Version: 2.1.10-2
Severity: normal
Tags: patch

Hi,

This is a reminder bug.

On debian, any semodule operation is unbearably slow.

Dominick Grift has found that adding the following lines to
/etc/selinux/semanage.conf was fixing this.

# expand-check check neverallow rules when executing all semanage commands.
# Large penalty in time if you turn this on.
expand-check=0
 

Other parameter could also be used to optimize the speed in some operations:

# usepasswd check tells semanage to scan all pass word records for home directories
# and setup the labeling correctly.  If this is turned off, SELinux will label /home
# correctly only.  You will need to use semanage fcontext command.
# For example, if you had home dirs in /althome directory you would have to execute
# semanage fcontext -a -e /home /althome
usepasswd=False
bzip-small=true
bzip-blocksize=5

Cheers,

Laurent Bigonville
