Subject: file_contexts duplicates
Date: Fri, 15 Aug 2008 10:42:20 -0400 [thread overview]
Message-ID: <48A595CC.2020508@windriver.com> (raw)
I have a problem in which file_contexts gets to 11mb (152kb unique)
because of duplicates.
Using selinux-svn2950 and refpolicy-svn2780 I built the standard policy
distro=redhat
unknown perms=deny
no direct admin init
Now using the .pp files that got installed into /usr/share/selinux/standard
I attempted to create a 2nd policy by hand using semodule.
# export NAME=vikram
# mkdir -v -p \
/etc/selinux/$NAME/modules/active \
/etc/selinux/$NAME/contexts/files \
/etc/selinux/$NAME/policy
# cd /usr/share/selinux/standard
# semodule -v -n -s $NAME -b base.pp $(for i in *.pp ; do if [ "$i" !=
"base.pp" ] ; then echo -n "-i $i "; fi; done)
This command appears to run for eternity. But after investigation, it
seems setfiles is getting stuck up reading file_contexts. And is
relabeling the file system again and again because of the duplicate
definitions.
Shorting out setfiles lets the command complete in 30mins. ie
Transaction return 0. However because the file_contexts is 11mb of
duplicates. It cannot be used. Doing a:
# sort /etc/selinux/$NAME/contexts/files/file_contexts | uniq > clean
# mv clean /etc/selinux/$NAME/contexts/files/file_contexts
Produces a 152kb file.
Note: /etc/selinux/standard/context/files/file_contexts is 156kb
Relabeling the file system now with the new 152kb file. Causes
/usr/lib64 to get usr_t which causes massive denial at boot up. And
eventually haults login.
What in the world is going on? Where would I begin to debug these
problems: 1) Duplicates in file_contexts and 2) Missing contexts
