[PATCH] LSPP audit enablement: storing selinux ocontext and scontext
Dustin Kirkland
dustin.kirkland at us.ibm.com
Thu Oct 20 18:50:56 UTC 2005
Ok, sorry for the repeated posting of the patch. I'm trying to keep it
in sync with the feedback I'm receiving.
Steve Grubb asked that I remove the parts of the patch that defined the
LSPP message types, as he just posted a patch that did just that.
I'm complying and posting an updated patch here.
Thanks,
:-Dustin
