BIT-1048 #merged
I'm reverting the serializer version update for now as that breaks
Broccoli. Let's do that later for 2.2.
* topic/robin/topk-merge:
update documentation, rename get* to Get* and make hasher persistent
adapt to new folder structure
fix opaqueval-related memleak
synchronize pruned attribute
potentially found wrong Ref.
add sum function that can be used to get the number of total observed elements.
in cluster settings, the resultvals can apparently been uninitialized in some special cases
fix memory leaks
fix warnings
add topk cluster test
make size of topk-list configureable when using sumstats
implement merging for top-k.
add serialization for topk
make the get function const
topk for sumstats
well, a test that works..
implement topk.
Nice solution with the ComponentManager/TaggedComponent!
BIT-1049 #Merged Merged into master.
* origin/topic/jsiwek/faf-updates:
Fix some build errors.
Minor fix to file/protocol analyzer plugin reference doc.
Internal refactoring of how plugin components are tagged/managed.
Factor out the need for a tag field in Files::AnalyzerArgs record.
Add a distinct tag class for file analyzers.
Fix various documentation, mostly related to file analysis.
* topic/robin/bloom-filter-merge:
Using a real hash function for hashing a BitVector's internal state.
Support UHF hashing for >= UHASH_KEY_SIZE bytes.
Changing the Bloom filter hashing so that it's independent of CompositeHash.
Add new BiF for low-level Bloom filter initialization.
Introduce global_hash_seed script variable.

Made some class templates for code that seemed duplicated between
file/protocol tags and managers. Seems like it helps a bit and
hopefully can be also be used to transition other things that have
enum value "tags" (e.g. logging writers, input readers) to the
plugin system.
Slightly adapted after discussing with Bernhard. I also added one
further check.
* origin/fastpath:
fix segfault that could be caused by merging an empty bloom-filter with a bloom-filter already containing values.
CompositeHash.
We do this by hashing values added to a BloomFilter another time more
with a stable hash seeded only by either the filter's name or the
global_hash_seed (or Bro's random() seed if neither is defined).
I'm also adding a new bif bloomfilter_internal_state() that returns a
string representation of a Bloom filter's current internal state. This
is solely for writing tests that check that the filters end up
consistent when seeded with the same value.
- Added the known-devices log, and the script to log DHCP hostname per MAC address,
- Added DPD sig,
- Removed some scripts following a discussion with Seth.
This commit adds support for script-level specification of a seed to be used by
hashers. For example, if the given name of a Bloom filter is not empty, then
the seed used by the underlying hasher only depends on the Bloom filter name.
If the name is empty, we check whether the user defined a non-empty
global_hash_seed string variable at script and use it instead. If that script
variable does not exist, then we fall back to the initial seed computed a
Bro startup (which is affected ultimately by $BRO_SEED).
See Hasher::MakeSeed for details.
This cleans up internals of how analyzer instances get identified by the
tag plus any args given to it and doesn't change script code a user
would write.
with a bloom-filter already containing values.
I assume that it is ok to merge an empty bloom-filter with any bloom-filter -
if not we have to change the patch to return an error in this case.
