Description of problem:
The attached patches provide a pair of improvements that are on their way 
 (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 
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 

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

How reproducible:

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.
