Description Marin Sperl 2003-04-05 03:14:40 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
When mounting a NFS share from a tru64 Box (5.1) we get
different behaviour if we mount with the option noac or without.

Version-Release number of selected component (if applicable):
kernel-bigmem-2.4.18-27.7.x

How reproducible:
Always

Steps to Reproduce:
1. mount <IP>:/system /mnt
2. mount -onoac <IP>:/system /mnt1
3. stat /mnt/file /mnt1/file
    

Actual Results:  stat /mnt1/file /mnt/file
 File: "/mnt1/file"

 File: "/mnt/file"

Expected Results:  
See the differences in the UID: once: -2 and the other time 65534. /mnt is
normally mounted, /mnt1/ is mounted with noac.

By comparison this does not happen with UID 65533 or lower!
Comment 1 Marin Sperl 2003-04-05 03:17:31 EST
Oh - I forgot with ls the files the UID of -2 in fstat maps to 4294967294 and
not  to 65534!
Comment 2 Steve Dickson 2004-08-11 07:18:26 EDT
This is fixed in later kernels
