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.
