The hash function was internally casting the void* data argument into an
unsigned char* and then using values from that to index another internal
array that's dimensioned based on the assumption of 256 values possible
for an unsigned char (8-bit chars/bytes). This is probably a correct
assumption most of the time, but should be safer to use the limits as
defined in standard headers to get it right for the particular
system/compiler.
There was an unused uint8* casted variable in HashKey::HashBytes that
seemed like it might have been meant to be passed to H3's hash function
as an unfinished attempt to solve the 8-bit byte assumption problem, but
that doesn't seem as good as taking care of that internally in H3 so
users of the API are only concerned with byte sizes as reported by
`sizeof`. Removing the unused variable addresses #530.
Also a minor tweak to an hmac_md5 call that was casting away const from
one argument (which doesn't match the prototype).
- When Bro is given a PRNG seed, it now uses its own internal random
number generator that produces consistent results across sytems.
Note that this internal generator isn't very good, so it should only
be used for testing purposes.
- The BTest configuration now sets the environemnt variables TZ=UTC
and LANG=C to ensure consistent results.
- Fixing doc markup in logging.bro.
- Updating baselines.
