Herbert Xu eb02c38f01 crypto: api - Keep failed instances alive ... This patch reverts commit 9c521a200b ("crypto: api - remove instance when test failed") and fixes the underlying problem in a different way. To recap, prior to the reverted commit, an instance that fails a self-test is kept around. However, it would satisfy any new lookups against its name and therefore the system may accumlulate an unbounded number of failed instances for the same algorithm name. The reverted commit fixed it by unregistering the instance. Hoever, this still does not prevent the creation of the same failed instance over and over again each time the name is looked up. This patch fixes it by keeping the failed instance around, just as we would if it were a normal algorithm. However, the lookup code has been udpated so that we do not attempt to create another instance as long as this failed one is still registered. Of course, you could still force a new creation by deleting the instance from user-space. A new error (ELIBBAD) has been commandeered for this purpose and will be returned when all registered algorithm of a given name have failed the self-test.
