Fedorahosted site being sunset
by Steve Grubb
Hello,
I just wanted to raise awareness that the Fedorahosted.org domain is being
sunset at the end of this month.
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/
thread/BWSMCGZPPNG3JOCFQ6Z74MIBU7FG3KGB/
What this means is that the audit SVN repository will no longer be active at
the end of this month. The bug tracking system that is attached to
fedorahosted will also go away.
Fortunately we have a github mirror of the svn repo and we will finish
transitioning to it going forward. If you wanted to have a copy of the svn
repo before its permanently gone, this is your notice to do it before the end
of the month.

[RFC] [PATCH] audit: log module name on init_module
by Richard Guy Briggs
This adds a new auxiliary record MODULE_INIT to the SYSCALL event.
We get finit_module for free since it made most sense to hook this in to
load_module().
