hashcat/src/interface.c
Jens Steube d7fb2ffa06 Fixed both a false positive and a false negative in -m 21800. Previously, 
only the first hash in a multihash list was marked as cracked, regardless
of which hash was actually cracked. For example, if the second hash was
cracked, it incorrectly marked the first as cracked and left the second
uncracked. This issue only affected beta versions and only in multihash
cracking mode.

Added deep-comp kernel support for Kerberos modes 28800 and 28900,
enabling multihash cracking for the same user in the same domain, even if
the password was changed or the recording was bad.

Added a rule ensuring that device buffer sizes for password candidates,
hooks, and transport (tmps) must be smaller than 1/4 of the maximum
allocatable memory. If not, hashcat now automatically reduces kernel-accel
down to 1, then halves the number of threads and restores kernel-accel up
to its maximum, repeating until the size requirement is met.

Fixed salt length limit verification for -m 20712.

Fixed password length limit for -m 14400.

Fixed unit test salt generator for -m 21100, which could produce duplicate
hashes under certain conditions.

Added the OPTS_TYPE_NATIVE_THREADS flag to the following hash modes
(after benchmarking): 7700, 7701, 9000, 1375x, 1376x, 14800, 19500, 23900.
