[PATCH] Keys: Replace duplicate non-updateable keys rather than failing
Cause an attempt to add a duplicate non-updateable key (such as a keyring) to a keyring to discard the extant copy in favour of the new one rather than failing with EEXIST: # do the test in an empty session keyctl session # create a new keyring called "a" and attach to session keyctl newring a @s # create another new keyring called "a" and attach to session, # displacing the keyring added by the second command: keyctl newring a @s Without this patch, the third command will fail. For updateable keys (such as those of "user" type), the update method will still be called rather than a new key being created.
