This type is used by Conn and Analyzer to hold onto timers being added and removed. We
don't expect the elements in those lists to maintain an order as the list is being
modified.
This fixes a "bug" with List where remove_nth() can be an O(n) operation when it doesn't
need to be. remove_nth for lists that don't necessarily need to keep an order can be an
O(1) operation instead.
This commit switches UID hashing from md5 to a highway hash. It also
moves the salt value out of the file plugin - and makes it
installation-specific instead - it is moved to the global namespace.
There now are digest hash functions to make "static"
installation-specific hashes that are stable over workers available to
everyone; hashes can be 64, 128 or 256 bits in size.
Due to the fact that we switch the file hashing algorithm, all file
hashes change.
The underlyigng algorithm that is used for hashing is highwayhash-128,
which is significantly faster than md5.
* origin/topic/seth/more-file-type-ident:
Adds a note in NEWS about the signature addition and restructuring
Fixes a small bug in one signature with a duplicate name.
Organized and added to the shipped file identification signatures.
The places that used md5 basically already used it as a digest
algorithm. Switching to a digest just means that the internal values
used to not change between runs - which is actually wanted in these
cases.
This commit also removes our special cmake subdirectory. We don't expose
highwayhash in headers anymore - so we can just treat it as an internal
implementation choice that is not directly exposed to plugins.
- Added test case and adjusted whitespace in merge
* 'stats-logging-fix' of https://github.com/brittanydonowho/zeek:
Fixed stats.zeek to log all data before zeek terminates rather than return too soon
There's now a couple placeholder/unimplemented status values in Broker
related to upcoming routing features that we don't want to handle
explicitly for compatibility reasons, but also don't want the compiler
warning about unhandled values in the switch.
- Minor whitespace adjutment in merge
* origin/topic/vern/any-typetype-when-fix:
bug fixes for using "when" in functions that have a local of type "any"
This commit moves some of the hash datastructures and code from
util.cc into Hash.cc - where it seems more appropriate.
It also starts to make more Keyed hash functions available - still
using siphash as the default 64 bit keyed hash, but also making
128 and 256 bit highway hashes available.
There already are a few other functions that are defined but not
yet implemented - these will be "static" keyed hashes - which use
an installation specific key. These will be used to, e.g., get
rid of md5 hashing for the generation of file UIDs.
This function just calculates the chosen digest and returns the result
in either the passed buffer, or in a static buffer. Basically a superset
to the surprisingly popular internal_md5.
