Description David Howells 2005-11-22 15:07:17 UTC

+++ This bug was initially created as a clone of Bug #173486 +++ 
 
From Bugzilla Helper: 
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.4; Linux) KHTML/3.4.2 (like 
Gecko) 
 
Description of problem: 
The attached patches provide a pair of improvements that are on their way  
upstream:  
  
 (1) A patch to add a keyctl function to permit userspace to set the expiry  
     times on a key.  
  
 (2) A patch that when a key is linked into a keyring causes any links from  
     that keyring to keys that match the new key's type and description to be  
     discarded.  
  
The second patch makes maintenance of keyrings easier, especially when keys  
are timing out and having to be replaced - the old keys get then discarded  
automatically.  
 
Version-Release number of selected component (if applicable): 
 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
The facility provided by patch (1) does not exist without this patch. With    
this patch and an updated keyutils package, the following should create a new    
key, add it to the session keyring and cause it to timeout after 30 seconds:    
    
        keyctl timeout `keyctl add user a a @s` 30    
    
With patch (2), doing:    
    
        keyctl link `keyctl add user a a @s` @s   
        keyctl show  
  
Will show two links to the new key in the session keyring before the patch is  
applied, and one after.  
 
Additional info: 
 
These patches are upstream in Andrew Morton's kernel.  
  
The keyutils will need updating for the facility provided by the first patch  
to become available.
