Subject: Recommended location of setkey configuration file?
Date: Fri, 9 Mar 2007 12:05:31 -0500	[thread overview]
Message-ID: <200703091205.32460.paul.moore@hp.com> (raw)

All of the following is in regards to RHEL5 and the MLS policy.

I'm trying to use a configuration file with setkey to setup the IPsec SPD in 
the kernel at boot.  Initially I created the configuration file 
as /etc/racoon/setkey.conf and put a line in my rc.local to run setkey like 
so:

 /sbin/setkey -f /etc/racoon/setkey.conf

I ran into two problems with this approach (AVCs posted below):

***
type=AVC msg=audit(1173457995.695:303): avc:  denied  { use } for  pid=2102 
comm="setkey" name="console" dev=tmpfs ino=725 
scontext=system_u:system_r:setkey_t:s0-s15:c0.c1023 
tcontext=system_u:system_r:init_t:s0-s15:c0.c1023 tclass=fd
type=AVC msg=audit(1173457995.695:303): avc:  denied  { use } for  pid=2102 
comm="setkey" name="console" dev=tmpfs ino=725 
scontext=system_u:system_r:setkey_t:s0-s15:c0.c1023 
tcontext=system_u:system_r:init_t:s0-s15:c0.c1023 tclass=fd
type=AVC msg=audit(1173457995.695:303): avc:  denied  { use } for  pid=2102 
comm="setkey" name="console" dev=tmpfs ino=725 
scontext=system_u:system_r:setkey_t:s0-s15:c0.c1023 
tcontext=system_u:system_r:init_t:s0-s15:c0.c1023 tclass=fd
type=AVC msg=audit(1173457995.721:304): avc:  denied  { search } for  pid=2102 
comm="setkey" name="racoon" dev=dm-0 ino=491816 
scontext=system_u:system_r:setkey_t:s0-s15:c0.c1023 
tcontext=system_u:object_r:ipsec_conf_file_t:s0 tclass=dir
***

The first problem involving fd use seems to have a rather simple fix, which I 
don't imagine should cause any adverse affects:

 init_use_fds(setkey_t)

However, the second problem of setkey not being allowed to search 
the /etc/racoon directory makes me believe I'm not placing my setkey.conf in 
the right location, or I simply have it named incorrectly.  Yet a quick 
search through the Reference Policy doesn't show an obvious name or location.  
My hunch is that any location under /etc should work, i.e. /etc/setkey.conf, 
but I was curious to see what the "recommended" solution is ...

Thanks.
