Years ago there was a commit to the Linux kernal that strangly had no author. This got some attention of several of the developers.
Looking into the code that had to deal with network transmission. there was a section that if you tried to get network access in a unusual way had a check that was written something like this.
If (usr_permission = ROOT) ... Instead of If (usr_permission == ROOT) ...
The first giving the user root if invoked and the second checking to see if the user was root.
It's widely thought this was the NSA or some other intelligence agency trying to backdoor lin Linux.
The other side of that coin is the NSA developing SELinux
This is because NSA has two roles: eavesdropping on foreign adversaries, and protecting our internal systems from adversaries. Under the first role, they might introduce an exploit known only to themselves. Under the second, they help protect US systems from exploits known to others.
