Description Russell Coker 2004-09-09 15:41:45 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko)

Description of problem:
When vipw creates a new /etc/passwd file it must first read the context of the old file and apply it to the new one.

Otherwise the file gets type shadow_t which is only readable by about a dozen programs and the system becomes almost unusable (will not boot correctly or allow logins).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Run SE Linux with strict policy, run "vipw" and make some changes.

Actual Results:  # ls -lZ /etc/passwd
-rw-r--r--  0  root system_u:object_r:shadow_t       /etc/passwd

Expected Results:  #ls -lZ /etc/passwd
-rw-r--r--  root root system_u:object_r:etc_t          /etc/passwd

The code to do this was there but not enabled.  Fixing in 2.12a-8.
