Description Jeremy Katz 2007-09-20 19:01:44 UTC

Following Dan's instructions for setting up pam_namespace with an xguest user, I
can't login as xguest.

avc errors are about xdm_t creating files labeled etc_t when trying to copy the
/etc/skel bits, but it shouldn't be trying to create them as etc_t anyway I
don't think.

Comment 1 Tomas Mraz 2007-09-20 19:40:09 UTC

Can you try to modify /etc/security/namespace.init so it contains 
cp -aT --no-preserve=context .....
instead of
cp -aT .....

Does it help?

Comment 2 Tomas Mraz 2007-09-20 19:40:42 UTC

If not, what are all the AVCs?

Comment 3 Jeremy Katz 2007-09-20 19:53:30 UTC

That helps somewhat...

and similar for all of the files.  According to audit2allow
  allow xdm_xserver_t unconfined_tmpfs_t:file { read write };

Comment 4 Tomas Mraz 2007-09-20 20:25:02 UTC

I'll add the --no-preserve=context to the next pam build however the rest has to
be fixed in the policy.

Comment 5 Daniel Walsh 2007-09-21 14:48:15 UTC

Tomas the patch I sent you this morning fixes these.
