These allow packet analyzers to register ports as identifiers to forward from
parent analyzers, while also adding those ports to the now-global
Analyzer::ports table at the same time.
This allows us to create an EnumType that groups all of the analyzer
tag values into a single type, while still having the existing types
that split them up. We can then use this for certain events that benefit
from taking all of the tag types at once.
Merge includes small changes, e.g. fixing the comsumption of remaining
raw data.
* 'master' of https://github.com/FlyingWithJerome/zeek:
remove excussive fields in dns_svcb_rr
address code reviews (formatting and type and intrusiveptr)
newlines at the end of test outputs
lazy commit
use tabs in init-bare.zeek
add svcb test case
add a dns https test case
remove test logs
fix a few syntax errors
initial commit for SVCB/HTTPS records
* origin/topic/vern/remove-uu:
fix up for linking w/ doc update
documentation update
script simplification that removes an unnecessary &is_assigned
removing -uu functionality and associated script analysis now no longer needed
Changes during merge:
- Add dedicated test (w/ trace "client_timestamp_enabled.pcapng" from Cloudshark)
- Change types from signed to unsigned.
- Add cast for bit-shifting operand.
- clang-format run
Add a small cache in front of the parse method. This cache should
reduce most of the calls to parse, and ultimately save memory because
redundant versions of the parsed strings will not be created in memory.
Move the parsing itself to the proxies where the caching can be more
efficient.
This could lead to a noticeable (single-percent) performance
improvement.
Most of the functionality for this is in the packet analyzers that now
cache ignore_chesksums_nets.
Based on a patch by Arne Welzel (Corelight).
* origin/topic/vlad/bogon:
Zeekygen doesn't support comments on set members
Add 6to4 addresses, if the matching IPv4 address is private
Update Site::private_address_space to latest IANA networks
* topic/christian/cluster-controller:
Add a cluster controller testcase for agent-controller checkin
Add zeek-client via new submodule
Update baselines affected by cluster controller changes
Introduce cluster controller and cluster agent scripting
Establish a separate init script when using the supervisor
Add optional bare-mode boolean flag to Supervisor's node configuration
Add support for making the supervisor listen for requests
Add support for setting environment variables via supervisor
This is a preliminary implementation of a subset of the functionality set out in
our cluster controller architecture. The controller is the central management
node, existing once in any Zeek cluster. The agent is a node that runs once per
instance, where an instance will commonly be a physical machine. The agent in
turn manages the "data cluster", i.e. the traditional notion of a Zeek cluster
with manager, worker nodes, etc.
Agent and controller live in the policy folder, and are activated when loading
policy/frameworks/cluster/agent and policy/frameworks/cluster/controller,
respectively. Both run in nodes forked by the supervisor. When Zeek doesn't use
the supervisor, they do nothing. Otherwise, boot.zeek instructs the supervisor
to create the respective node, running main.zeek.
Both controller and agent have their own config.zeek with relevant knobs. For
both, controller/types.zeek provides common data types, and controller/log.zeek
provides basic logging (without logger communication -- no such node might
exist).
A primitive request-tracking abstraction can be found in controller/request.zeek
to track outstanding request events and their subsequent responses.
The supervisor does not require the full weight of scripts that
init-default.zeek brings with it. The new file, init-supervisor.zeek, contains
only what's required by the supervisor in addition to the other always-loaded
init files.
When omitted, the node inherits the Supervisor's bare-mode
status. When true/false, the new Zeek node will enable/disable bare
mode, respectively. It continues to load any scripts passed at the
command line and in the additional scripts list already provided in
the node configuration.
Includes testcase.
The supervisor now starts listening on the configured Broker default address and
port when the new boolean SupervisorControl::enable_listen is T. Listening
remains disabled by default. Listening allows nodes to communicate with the
supervisor via the events laid out in control.zeek, to conduct further node
management.
The NodeConfig record now has a table for specifying environment variable names
and values, which the supervisor sets in the created node.
This also repositions the cpu_affinity member to keep the order the same in
the corresponding script-layer and in-core types.
Includes testcase.
