Description Steve Grubb 2012-08-30 17:02:29 UTC

Description of problem:
Daemon programs should have full RELRO support enabled for extra protection. They should also have gcc's PIE flag enabled, too.

FILE                                                TYPE        RELRO    PIE 
/sbin/arp                                           daemon      partial  no  

You can use this program for testing:

Comment 1 Jiri Popelka 2012-09-03 13:15:31 UTC

I don't think /sbin/arp fits into this daemon category.
Yes, it can be run (only if /etc/ethers exists) during boot to load static arp entries from the ethers file.
But as you can see in arp-ethers.service it's a "oneshot" type so it exits immediately after loading the entries.

Have I missed anything or we can close this BZ ?

Comment 2 Steve Grubb 2012-09-05 10:42:23 UTC

This bug was filed to get the flags correct so that we can make claims in our common criteria security target. The intent was that we could say all setuids are compiled with these flags, all daemons are compiled with those, all apps have other flags. We really didn't want to start making exceptions to the blanket policy.

Comment 3 Jiri Popelka 2012-09-05 10:53:17 UTC

My point has been that /sbin/arp is not a deamon nor setuid.

Comment 4 Steve Grubb 2012-09-05 11:07:19 UTC

Its started by a .service file. Which means if we start picking and choosing which ones are daemon and which ones aren't, it gets complicated. I can help you with the patch if you think it's helpful.

Comment 5 Jiri Popelka 2012-09-05 11:43:06 UTC

Ok. Then easiest would be to add these flags to spec file and compile all the tools with PIE and full RELRO flags then modifying Makefile just for arp.
