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):
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
Will show two links to the new key in the session keyring before the patch is
applied, and one after.
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.
