Description Thomas DuBuisson 2010-04-17 17:47:20 UTC 
Description of problem:
Despite the permissions showing global read access, /proc/sys/vm/mmap_min_addr can not be read by normal users.


Version-Release number of selected component (if applicable):
2.6.32.11-99 is where I see the issue
2.6.32.11-90 works fine.

How reproducible:
100%

Steps to Reproduce:
1. Boot using kernel 2.6.32.11-99
2. cat /proc/sys/vm/mmap_min_addr
  
Actual results:
ERROR permission denied

Expected results:
"0" or "4096" or whatever your configuration has.

fixed upstream in 2.6.34.  If you need this in an older kernel please reopen this bug and I can backport.
