Description Will Woods 2008-04-23 17:55:04 UTC

I used preupgrade to upgrade two systems from F7 (with updates) to rawhide.

On both systems, my normal user (wwoods) unexpectedly ended up with the user_u
SELinux context, rather than unconfined_u. 

I only noticed it because su appeared to be missing.

Comment 1 Will Woods 2008-04-23 18:31:18 UTC

F7 users (as in RHEL5) have a default context of user_u:system_r:unconfined_t.

F8 has unconfined_u:system_r:unconfined_t:s0-s0:c0.c1023.

So I guess the problem is that we've redefined the meaning of user_u.

Comment 2 Will Woods 2008-04-23 20:38:11 UTC

A workaround for affected systems: 

  semanage login -m -s unconfined_u -r SystemLow-SystemHigh __default__

should give users the default SELinux context used for new F9 installs.

Comment 3 Daniel Walsh 2008-04-23 20:41:12 UTC

Yes we need to convert user_u to unconfined_u.  This is a blocker bug.

Needs to be fixed.

Will could you verify that
selinux-policy-3.3.1-39.fc9 fixes the problem.

Comment 4 Will Woods 2008-04-23 21:38:42 UTC

Does it need to be installed as part of the upgrade from F7? (That is, do I need
to wait for it to land in rawhide to test the fix?)

Comment 5 Daniel Walsh 2008-04-24 21:07:47 UTC

You can test it by executing 

rm -rf /etc/selinux
rpm -Uhv --oldpackage selinux-policy*f7  /* Whatever F7 policy was*/

Then update to F9 policy and check to see if you login in as unconfined_u

semanage login -l | grep __default__

Comment 6 Will Woods 2008-04-24 23:49:20 UTC

I think the fix is confirmed.

I upgraded from F7 to F9 (where my user had user_u). Next I installed the old f7
policy packages and rebooted into rescue mode (to simulate the installer). 

I then upgraded the system to selinux-policy-3.3.1-40.fc9. It took a *long* time
for %post to run, but now everything works fine.

Comment 7 Will Woods 2008-04-29 22:30:12 UTC

Yep, confirmed the fix with an upgrade to today's rawhide.
