Description Jeremy Katz 2007-07-18 09:29:50 EDT
grub needs to be allowed execmem (and used to be)

avc: denied { execmem } for comm="grub" egid=0 euid=0 exe="/sbin/grub" exit=-13
fsgid=0 fsuid=0 gid=0 items=0 pid=9454
scontext=system_u:system_r:unconfined_t:s0 sgid=0
subj=system_u:system_r:unconfined_t:s0 suid=0 tclass=process
tcontext=system_u:system_r:unconfined_t:s0 tty=pts4 uid=0
Comment 1 Daniel Walsh 2007-07-18 09:43:42 EDT
Currently grub (bootloader_t) has execmem but we do not have a transition from
unconfined_t.  It only transitions from init.  But it looks like this is true in
FC7 and Rawhide.

I will add the transition back to rawhide.  I believe there were other problems
with this transition in the past and that is why I turned it off, but I will
turn it back on and see what happens.  

Fixed in selinux-policy-3.0.3-1.fc8
Comment 2 Daniel Walsh 2007-08-22 10:15:17 EDT
