Hello,

I am using the elrepo fglrx driver and kmod packages (14.12-1.el6) with
Scientific Linux SL6x.  Just recently, rkhunter has started to complain
about a file /dev/shm/sem.__AMD_GL_CACHE__0016fe1386291f1d_20.  From the
name, it looks as if the file is related to the driver and the file looks
pretty innocent - 32 bytes consisting of a 1 and 31 0s.  If I delete the
file, it eventually regenerates, although I don't know what triggers the
regeneration.  Googling on the file name produces no results, but the
documentation for the closed source driver says that you need /dev/shm for
3D effects.  I can't find any filenames in that documentation and I'm not
consciously using any 3D effects.

The one thing that has changed recently is that I have added a second screen
(without xinerama).  The second screen was there for about a week before the
first rkhunter warning.

Can someone reassure me that the fglrx driver does put files with that kind
of name in /dev/shm so that I can whitelist them for rkhunter?
