A cipher instance is added to the list of instances unconditionally regardless of whether the associated test failed. However, a failed test implies that during another lookup, the cipher instance will be added to the list again as it will not be found by the lookup code. That means that the list can be filled up with instances whose tests failed. Note: tests only fail in reality in FIPS mode when a cipher is not marked as fips_allowed=1. This can be seen with cmac(des3_ede) that does not have a fips_allowed=1. When allocating the cipher, the allocation fails with -ENOENT due to the missing fips_allowed=1 flag (which causes the testmgr to return EINVAL). Yet, the instance of cmac(des3_ede) is shown in /proc/crypto. Allocating the cipher again fails again, but a 2nd instance is listed in /proc/crypto. The patch simply de-registers the instance when the testing failed. Signed-off-by:
