Description Mark Wielaard 2011-08-11 09:32:23 UTC
Description of problem:

prelinking a library installed in my home directory doesn't work.

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

selinux-policy-targeted-3.10.0-16.fc17.noarch

How reproducible:

Always.

Steps to Reproduce:

I have a testsuite which runs some tests on generated libraries, one of the tests prelinks the library.

Executing: /usr/sbin/prelink -vfNR -r 0x6400000 ./libuprobeslibgcc-O3default-pre
link-debug.so
prelink failed: /usr/sbin/prelink: Could not set security context for ./libuprob
eslibgcc-O3default-prelink-debug.so: Permission denied
FAIL: uprobeslibgcc-O3default-prelink-debug prelink ./libuprobeslibgcc-O3default-prelink-debug.so
  
Actual results (in /var/log/messages):

Aug 10 23:49:15 rawhide kernel: [ 6349.447453] type=1400 audit(1313012955.298:17): avc:  denied  { relabelfrom } for  pid=32608 comm="prelink" name="libuprobeslibgcc-O3default-prelink-debug.so.#prelink#.VuIHOd" dev=dm-1 ino=262883 scontext=unconfined_u:unconfined_r:prelink_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file

Expected results:

prelinked library

Additional info:

This works fine under f14 and f15.

Fixed in selinux-policy-3.10.0-19.fc16

Comment 2 Daniel Walsh 2011-08-11 15:55:49 UTC
F14 and F15 did not confine prelink...  We probably should turn that back on for F16.
