The reason for this is threshold, setting. I think the interfaces are
getting more complicated and one AVC that is looking for read ends up
being two far different from the threshold, so audit2allow does not
report it.
For example.
node=(removed) type=AVC msg=audit(1271587735.632:422): avc: denied {
getattr } for pid=13239 comm="openvpn"
path="/home/bbaetz/.pki/vpn01_cacert.pem" dev=dm-3 ino=565334
scontext=system_u:system_r:openvpn_t:s0
tcontext=unconfined_u:object_r:home_cert_t:s0 tclass=file
node=(removed) type=SYSCALL msg=audit(1271587735.632:422): arch=c000003e
syscall=5 success=yes exit=0 a0=6 a1=7fffd84f4a20 a2=7fffd84f4a20 a3=18
items=0 ppid=13235 pid=13239 auid=4294967295 uid=0 gid=0 euid=0 suid=0
fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="openvpn"
exe="/usr/sbin/openvpn" subj=system_u:system_r:openvpn_t:s0 key=(null)
Finds userdom_read_home_certs but it's threshold is two far off, so it
reports nothing.
I think we should either eliminate the threshold and report the best
interface that we have, and let the policy writer decide if he wants the
match.
If you look at the interface userdom_read_home_certs.
[InterfaceVector userdom_read_home_certs $1:source ]
$1,home_cert_t,file,read,lock,getattr,open,ioctl
$1,home_cert_t,dir,ioctl,search,read,lock,open,getattr
$1,home_cert_t,lnk_file,read,getattr
$1,home_root_t,dir,getattr,open,search
$1,home_root_t,lnk_file,read,getattr
$1,user_home_dir_t,dir,getattr,open,search
$1,user_home_dir_t,lnk_file,read,getattr
A domain that is allowed to search the homedir is always going to
generate an AVC that is a long way off.
I thing we should either remove the bastards and just add all as childs,
or recode it like the attachment.
