The ssl_history field may grow unbounded (e.g., ssl_alert event). Prevent this
by capping using a configurable limit (default 100) and raise a weird once reached.
Unsure what it's used for today and also results in the situation that on
some platforms we generate a reporter.log in bare mode, while on others
where spicy is disabled, we do not.
If we want base/frameworks/version loaded by default, should put it into
init-bare.zeek and possibly remove the loading of the reporter framework
from it - Reporter::error() would still work and be visible on stderr,
just not create a reporter.log.
The dump-events baseline changes are pure noise and have spurred confusion
for internal and external contributors. For example, adding new
analyzers have perturbed orderings of sets holding analyzer tags.
Running in non-bare mode, the baselines change almost whenever any of the
record types attached to connections change in the default scripts. This
causes continuous and seemingly little useful updates to the baselines.
This change switches the test to run in bare mode and explicitly loads
just base/protocols/conn and base/protocols/smtp. The primary intention
of the test should be testing the functionality of the misc/dump-events
script, not the raised events of all loaded default scripts (for that the
used PCAP is too narrow).
Protocol specific scripts that do want to leverage misc/dump-events for
baseline creation of their or their analyzer's events can add additional
specific tests with suitable PCAP files.
Setting this option to false does not count missing bytes in files towards the
extraction limits, and allows to extract data up to the desired limit,
even when partial files are written.
When missing bytes are encountered, files are now written as sparse
files.
Using this option requires the underlying storage and utilities to support
sparse files.

* origin/topic/jazoff/gh-3268:
Fix check for emailed notices
Changes: Added a test-case printing email_delay_tokens to compare email vs
non-email notice types. Previously, both notice types would have email
delay tokens at that point in the flow.
When http_reply events are received before http_request events, either
through faking traffic or possible re-ordering, it is possible to trigger
unbounded state growth due to later http_requests never being matched
again with responses.
Prevent this by synchronizing request/response counters when late
requests come in.
Also forcefully flush pending requests when http_replies are never
observed either due to the analyzer having been disabled or because
half-duplex traffic.
Fixes#1705
This works around the new semantics of is_orig=T for "connections"
from DHCP servers to broadcast addresses. IMO, having the server address
as originator in the conn.log is still more intuitive.
The input framework currently gives a rather opaque error message when
encountering a line in which a required value is not provided. This
change updates this behavior; the error message now provides the record
element (or the name or the index element) which was not set in the
input data, even though it is required to be set by the underlying Zeek
type.
This test triggered ubsan by putting a function with the wrong type
as a post-processor into the .shadow file. Don't do that.
Likely Zeek should provide a better error message, but hand-crafting
.shadow files isn't what is normally done and this is to fix the
master build for now.
* topic/awelzel/3112-log-suffix-left-over-log-rotation:
cluster/logger: Fix leftover-log-rotation in multi-logger setups
cluster/logger: Fix global var reference
Populating log_metadata during zeek_init() is too late for the
leftover-log-rotation functionality, so do it at script parse time.
Also, prepend archiver_ to the log_metadata table and encoding function
due to being in the global namespace and to align with the
archiver_rotation_format_func. This hasn't been in a released
version yet, so fine to rename still.
Closes#3112

RemoveGlobal() method for Scope class + simplifying interfaces
This seems to have relied on the reading file twice behavior simply
testing that 16 lines are observed. Switch to using two separate
files and doing a system("mv ...") to trigger the REREAD logic, there's
not force_update() needed and it wouldn't do anything if the file
hadn't changed anyway.
Found while writing documentation and being confused why
all lines and end_of_data() arrive twice during startup.
The test is a bit fuzzy, but does fail reliably without
the changes to Raw.cc
Also fix not checking dev in the MODE_REREAD path.
Closes#3053
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.
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.
