Hi Chuck, Herbert,
I was trying to bring my krb5 crypto lib patches up to date, but noticed that
the Camellia encryption selftests are failing (the key derivation tests work,
but the crypto tests failed).
After some investigation that didn't get anywhere, I tried the sunrpc kunit
tests that Chuck added - and those fail similarly (dmesg attached below). I
tried the hardware accelerated version also and that has the same failure.
Note that Chuck and I implemented the kerberos Camellia routines
independently.
David
