constraint violation problem

[Thorsten Scherf]

Following setup:

iucv instance is started via upstart to make iucv connections available
in a z/VM environment:

# cat /etc/init/iucv.conf 
start on runlevel [2345]
stop on runlevel [01]
respawn
exec /usr/bin/iucvtty lnxterm

iucvtty is running in init_t:

# ps -efZ|grep iucv
system_u:system_r:init_t:s0     root      1788     1  0 13:56 ? 00:00:00 /usr/bin/iucvtty
lnxterm

Using ts-shell to connect from a central server to this system produces
the following AVC:

type=AVC msg=audit(1368960989.210:22183): avc:  denied  { transition }
for  pid=1761 comm="login" path="/bin/bash" dev=dasda3 ino=379
scontext=system_u:system_r:local_login_t:s0
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tclass=process
type=SYSCALL msg=audit(1368960989.210:22183): arch=80000016 syscall=11

comm="bash" exe="/bin/bash"
subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null)

This is the output from audit2allow:

#!!!! This avc is a constraint violation.  You will need to add an
attribute to either the source or target type to make it work.
#Contraint rule: 
allow local_login_t unconfined_t:process transition;

What is the recommended way to avoid this AVC?

Cheers,
Thorsten
