This replaces generic reporter->Error() calls with the builtin-specific variety,
which gives better context in the resulting error messages (such as the script
and line causing it).
Includes corresponding baseline update in one affected btest.
* origin/topic/robin/gh-3561-forward-to-udp:
Update docs.
Add explicit children life-cycle management method to analyzers.
Spicy: Support UDP in Spicy's `protocol_*` runtime functions.
Add method to analyzer to retrieve direct child by name.
Extend PIA's `FirstPacket` API.
Spicy: Prepare for supporting forwarding to protocols other than TCP.
* origin/topic/christian/fix-zeekygen-crash:
Avoid segfault when generating Zeekygen docs on Zeek-internal identifiers.
Add btest for Zeekygen docs extraction on identifiers defined by the Zeek core.
This extends the ability to feed new payload back into Zeek's analyzer
pipeline from TCP to now also UDP.
Note: We don't extend this further to ICMP because the ICMP analyzer
cannot be dynamically instantiated (Zeek aborts when trying so). As
ICMP isn't very interesting from use-case perspective anyways, that
seems fine.
Closes#3561.
* origin/topic/robin/gh-3573-replaces-cleanup:
Fix packet analyzer replacement.
Spicy: Wenn replacing an analyzer add a component mapping.
Add component API to transparently remap one component to another one.
Move enabled/disabled functionality from analyzers into `Component` base class API.
This uses the new API to replace components internally.
With these changes in place, replacing protocol analyzers now don't
need to register their ports anymore if they match what the original
analyzer was using (because the old one's registrations will map
over).
Packet analyzer replacement doesn't quite work yet but will be fixed
in next commit.
Closes#3573.
Like traditional file analyzers, we now query Zeek's
`get_file_handle()` event for handles when a connection begins
analyzing an embedded file. That means that Spicy-side protocol
analyzers that are forwarding data into file analysis now need to call
Zeek's `Files::register_protocol()` and provide a callback for
computing file handles. If that's missing, Zeek will now issue a
warning. This aligns with the requirements Zeek's traditional protocol
analyzers. (If the EVT file defines a protocol analyzer to `replace`
an existing one, that one's `register_protocol()` will be consulted.)
Because Zeek's `get_file_handle()` event requires a current
connection, if a Spicy file analyzer isn't directly part of a
connection context (e.g., with nested files), we continue to use
hardcoded, built-in file handle. Scriptland won't be consulted in
that case, just like before.
Closes#3440.
Mainly, this should not crash. :-) The baseline output file also should remain
empty, since Zeekygen's staleness test should conclude that it's sufficiently
fresh.
While in Spicy code a hook priority is spelled `priority=4711` the
attribute is still called `&priority` (like in HILTI) and we rely on
exactly that name when e.g., extracting hook priorities for scheduling.
This change was introduced as part of
db98dc4193 and caused the default hook
priority for hooks defined in EVT files (intended to be -1000 to likely
schedule after e.g., hooks in the Spicy grammars) to be ignored. This
could then e.g., introduce issue when a `%done` hook would mutate state
exposed in an EVT hook (which now might not have seen the updated state
due to different scheduling).
Add localversion to the VersionDescription record and populate it
during version string parsing.
This change also modifies the version string syntax, removing the
deprecated dash (-) between beta|dev|rc and the commmit count; those
must now be separated by a period.
The test version strings were updated accordingly along with the
baseline.
