Description Ruben Kerkhof 2011-01-23 15:48:19 UTC
Description of problem:

Opening a vpn connection results in the following AVCs:

type=AVC msg=audit(1295797298.171:39383): avc:  denied  { execute } for  pid=19532 comm="pppd" name="unix_chkpwd" dev=vd
a1 ino=14436 scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:object_r:chkpwd_exec_t:s0 tclass=file
type=AVC msg=audit(1295797298.171:39383): avc:  denied  { read open } for  pid=19532 comm="pppd" name="unix_chkpwd" dev=
vda1 ino=14436 scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:object_r:chkpwd_exec_t:s0 tclass=file
type=AVC msg=audit(1295797298.171:39383): avc:  denied  { execute_no_trans } for  pid=19532 comm="pppd" path="/sbin/unix
_chkpwd" dev=vda1 ino=14436 scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:object_r:chkpwd_exec_t:s0 tclass=file

I'm using xl2tpd and pam authentication.

Comment 1 Daniel Walsh 2011-01-24 15:33:31 UTC
Looks like we need to add

auth_domtrans_chk_passwd(pppd_t)

Comment 2 Miroslav Grepl 2011-01-24 15:39:21 UTC
Ruben,
if you create the following local policy 

# cat mypol.te
policy_module(mypol,1.0)

require{
 type pppd_t;
}

auth_domtrans_chk_passwd(pppd_t)



and then execute

# make -f /usr/share/selinux/devel/Makefile
# semodule -i mypol.pp


does it work?

Comment 3 Ruben Kerkhof 2011-01-24 16:30:00 UTC
Hi Miroslav,

Yes, this works great, thanks!

There are only 2 AVCs left now:
type=AVC msg=audit(1295885268.911:46236): avc:  denied  { write } for  pid=12710 comm="pppd" name="wtmp" dev=vda1 ino=27047 scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:o
bject_r:wtmp_t:s0 tclass=file

and 

type=AVC msg=audit(1295885268.902:46234): avc:  denied  { setsched } for  pid=12710 comm="pppd" scontext=system_u:system_r:pppd_t:s0 tcontext=system_u:system_r:pppd_t:s0 tclass=pro
