[PATCH] keys: Discard duplicate keys from a keyring on link
Cause any links within a keyring to keys that match a key to be linked into
that keyring to be discarded as a link to the new key is added. The match is
contingent on the type and description strings being the same.
This permits requests, adds and searches to displace negative, expired,
revoked and dead keys easily. After some discussion it was concluded that
duplicate valid keys should probably be discarded also as they would otherwise
hide the new key.
Since request_key() is intended to be the primary method by which keys are
added to a keyring, duplicate valid keys wouldn't be an issue there as that
function would return an existing match in preference to creating a new key.
