* origin/topic/timw/3059-set-vector-conversion:
Fix conversion with record types
Add conversion between set and vector using 'as' keyword
Add std::move for a couple of variables passed by value
This is based on the discussion in zeek/zeek#2668. Using &default with tables
can be confusing as the default value is not inserted. The following example
prints an empty table at the end even new Service records was instantiated.
type Service: record {
occurrences: count &default=0;
last_seen: time &default=network_time();
};
global services: table[string] of Service &default=Service();
event zeek_init()
{
services["http"]$occurrences += 1;
services["http"]$last_seen = network_time();
print services;
}
Changing above &default to &default_insert will insert the newly created
default value upon a missed lookup and act less surprising.
Other examples that caused confusion previously revolved around table of sets
or table of vectors and `add` or `+=` not working as expected.
tbl_of_vector["http"] += 1
add tbl_of_set["http"][1];
Ad-hoc include module names in the global_ids() table. Table values will
have the type_name field set to "module" and their key in the table is
prefixed with "module " to avoid clashes with existing global identifiers
shadowing module names (Management::Node being an existing example).
Closes#3136
Avoids loosing state on a connection value when a connection is flipped.
Fixes up the NTP baseline as well where this was visible: analyzer_confirmation_info()
was raised for a connection value which was immediately forgotten due to
the subsequent connection flipping.
Closed#3028
When a JSON document contains key names containing colons or other
special characters that are not valid in Zeek identifiers, from_json()
cannot be used to parse such input.
This change allows a customizable normalization function.
Closes#3142.
While writing documentation about troubleshooting and looking a bit
at the older stats.log, realized we don't have the packet lag metric
exposed as metric/telemetry. Add it.
This is a Zeek instance lagging behind in network time ~6second because
it's very overloaded:
zeek_net_packet_lag_seconds{endpoint=""} 6.169406 1684848998092
* jgras/topic/jgras/event-ts:
Add compatibility tests for timestamped events.
Add timestamps to auto published broker events.
Add timestamps to manually published broker events.
Annotate scheduled events with intended timestamp.
Add timestamp to events.
One timestamp to ts rename during the merge.
This commit adds support for the connection_id extension, adds a trace
that uses DTLS 1.3 connection IDs, and adds parsing for the DTLS 1.3
unified header, in case connection IDs are not used.
In case connection IDs are used, parsing of the DTLS 1.3 unified header
is skipped. This is due to the fact, that the header then contains a
variable length element, with the length of the element not given in the
header. Instead, the length is given in the client/server hello message
of the opposite side of the connection (which we might have missed).
Furthermore, parsing is not of a high importance, since we are not
passing the connection ID, or any of the other parsed values of the
unified header into scriptland.
* amazing-pp/topic/fupeng/from_json_bif:
Implement from_json bif
Minor updates during merge: Moved ValFromJSON into zeek::detail for the
time being, removed gotos, normalized some error messages to lower case,
minimal test extension and added a raw reader input framework test reading
"json lines" as a demo, adding notes about the implicit type
conversions.
When multiple loggers are configured in a Supervisor controlled cluster
configuration, encode extra information into the rotated filename to
identify which logger produced the log.
This is similar to the approach taken for ZeekControl, re-using the
log_suffix terminology, but as there's only a single zeek-archiver
process and no postprocessors and no other side-channel for additional
information, we encode extra metadata into the filename. zeek-archiver
is extended to recognize the special metadata part of the filename.
This also solves the issue that multiple loggers in a supervisor setup
overwrite each others log files within a single log-queue directory.
The NTP mode provides us with the identity of the endpoints. For the
simple CLIENT / SERVER modes, flip the connection if we detect
orig/resp disagreeing with what the message says. This mainly
results in the history getting a ^ and the ntp.log / conn.log
showing the corrected endpoints.
Closes#2998.

The PktSrc::Stats object works with 64bit unsigned integers. Unfortunately,
libpcap's struct pcap_stat is using 32bit values and users have reported
the wrapping of these values being visible in their stats.log roughly every
7.5 hours (~160kpps).
This change moves tracking of link and drop counters into the PktSrc::Stats
object (like is done for received and bytes_received) and updates them
on a call to PcapSource::Statistics() with the difference to the
previous stats values to prevent the wrap from becoming visible to
script land.
This doesn't cover the case of the stats counters wrapping around multiple
times between two invocations of PktSrc::Statistics(). With the default
interval of 5 minutes for the stats script, this seems acceptable.
Closes#2791.
