Description of problem:


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


How reproducible:
Always

Steps to Reproduce:
1.smbmount //some/share /mnt/ -o uid=100000
2. ls -ld /mnt
    

Actual Results:  Actual Results:  The UID wraps around at 65535(and so does GID)
so the mount point gets owned by wrong UID.

Expected Results:  UID shouldn't wrap around of course..

Additional info:

The fix requires a patch to the kernel and also smbmnt:

Oh and this is present in all RH versions up to date, not just phoebe.

Comment 1 Jay Fenlason 2003-01-10 23:17:32 UTC
I'm reassigning this to the kernel maintainer.  Once the kernel uses a proper 
__kernel_uid_t, we'll see if samba 2.2.7a needs patching.

Comment 2 Panu Matilainen 2003-01-12 10:48:00 UTC
Oh by the point here was that you can't really change the __kernel_uid_t in 
middle of stable kernel series - see 
http://www.uwsg.iu.edu/hypermail/linux/kernel/0209.0/0678.html. With this patch 
in samba you don't need to break kernel binary compatibility.

This ancient bug got eventually fixed in RHEL, closing...
