SSSD calls system() to flush NSCD caching services.
Last modified: 2011-07-25 23:39:21 EDT
Description of problem:
In an attempt to flush NSCD if it is running, SSSD will call system(/usr/bin/nscd -i service) to flush the cache.
This is a problem from a SELinux standpoint because future policy writers will need to allow the sss-tools to have execute permission of all bin_t files.
It is preferable to directly fork/exec in this situation because then SELinux policy can support the nscd_domtrans call only which greatly reduces the scope of access required to make this work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Call any sss-tools application which alters the local database files.
The request works but SELinux polic would need to permit execute on bin_t types.
No requirement to execute bin_t types when calling nscd.
