Although the `prune-flows` option was removed with a5587fec2e,
when documentation for the suricata.yaml config file was added with
b252b0d, this option was also included - as has remained until now.

1. Use https instead of http everywhere
2. Organize and annotate references by
- Referenced by ET/Open and ET/Pro
- URL resolves and works as intended (to provide supplemental
information regarding a reference value, e.g., bug id, cve
value)
- URL no longer resolves
- URL resolves but doesn't work as intended (to provide
supplemental information)
- Not referenced by ET/Open nor ET/Pro
- URL resolves and works as intended (to provide supplemental
information regarding a reference value, e.g., bug id, cve
value)

DCERPC/TCP tends to return the same values for invalid and incomplete
headers. As a result of this, invalid headers and any traffic following
it is buffered and processed later on assumed to be valid DCERPC traffic.
Fix this by clearly defining error and incomplete data and taking
appropriate actions.

As it is not always the first frame to be created :
if it is not enabled, it does not get created, and other enabled
frames may be created first. see use of FrameConfigTypeIsEnabled
This resulted that this other frame got its length updated
on stream end, which led to false positives.
Resorting on FRAME_STREAM_TYPE is more consistent.
Ticket: 7213
In the DCERPC over TCP pcap, logging and rule matching is disrupted by adding a simple rule:
alert tcp any any -> any any (flow:to_server,established; \
dce_iface:5d2b62aa-ee0a-4a95-91ae-b064fdb471fc; dce_opnum:1; \
dce_stub_data; content:"|42 77 4E 6F 64 65 49 50 2E 65 78 65 20|"; \
content:!"|00|"; within:100; distance:97; sid:1; rev:1; )
Works: alert + 3 dcerpc records.
But when adding a trivial rule:
alert tcp any any -> any any (flow:to_server,established; \
dce_iface:5d2b62aa-ee0a-4a95-91ae-b064fdb471fc; dce_opnum:1; \
dce_stub_data; content:"|42 77 4E 6F 64 65 49 50 2E 65 78 65 20|"; \
content:!"|00|"; within:100; distance:97; sid:1; rev:1; )
alert tcp any any -> any any (dsize:3; sid:2; rev:1; )
The alert for sid:1 disappears and also there is one dcerpc event less.
In the single rule case we can aggressively free the transactions, as there
is only an sgh in the toserver direction.
This means that when we encounter the 2nd REQUEST, the first 2 transactions
have already been processed and freed. So for the 2nd REQUEST we open a new
TX and run inspection and logging on it.
When the 2nd rule is added, it adds toclient sgh as well. This means that we
will now slightly delay the freeing of the transactions.
As a consequence we still have the TX for the first REQUEST when the 2nd REQUEST
is parsed. This leads to the 2nd REQUEST re-using the TX. Since the TX is
already marked as inspected, it means the toserver rule now no longer matches.
Also we're not logging this TX correctly now.
This commit fixes the issue by not "finding" a TX that as already been
marked complete in the search direction.
Bug #7187.
The `app-layer-protocol` keyword inconsistently checks whether the
alproto is ALPROTO_UNKNOWN. In the regular match function it isn't
checked, in the prefilter function its checked for all but the "either"
mode.
This leads to false positives for negated matching, as an expression
like "!tls" will match if checked against ALPROTO_UNKNOWN.
This patch adds the checking everywhere. The keyword returns no match as
long as the alproto is ALPROTO_UNKNOWN.
Bug: #7241.
base64 crate is updated to the latest version 0.22.1. This came with
several API changes which are applied to the code. The old calls have
been replaced with the newer calls.
This was done following the availability of better fns to directly
decode into slices/vectors as needed and also that previous version was
too old.
Along with this change, update the Cargo.lock.in to reflect all changes
in the package versions.
Task 7219
Remove the ThreadExitPrintStats callback, this is the only logger that
was actually using it, and this logger is marked for deprecation. This
allows us to remove the callback from the registration signature.
Ticket: #7227
Remove the callback to print stats on thread exit. The counter value
was never being used and this helps us get rid of this callback
altogether as their is only one other usage of it.
Ticket: #7227
Using OutputCtx results in the low level output-tx packet logger being
aware of Suricata's higher level loggers that use OutputCtx, for the
low level logger this is purely opaque data that may not be an
OutputCtx for custom loggers.
Ticket: #7227
Rename OutputRegisterFlowLogger to SCOutputRegisterFlowLogger and
document in the header file.
Mark other functions in the header file as part of the internal API.
Ticket: #7227
Rename OutputRegisterPacketLogger to SCOutputRegisterPacketLogger as
its part of the public API and document its parameters.
Comment on the other functions in the header that they are part of the
internal API.
Ticket: #7227
Loggers need an ID uniquely identify them for profiling. To help with
loggers registered at runtime (library, plugins), provide a
LOGGER_USER that can be used. It won't provide per-logger details if
they have more than one, but will provide a total for all their
registered loggers.
Ticket: #7227
PgsqlTransactionState has a variant named "Init" which is a little too
generic to export to C. Fortunately this method doesn't need to be
exposed to C, instead remove it as it was only called by
rs_pgsql_tx_get_alstate_progress which also doesn't need to be public
or expose to C.
Ticket: #7227
The use of OutputCtx as the data type for initdata was leaking Eve
submodule logic into the low level packet logger. Instead use void *,
as the packet logging module is not concerned with the type of data
here.
Also document this initdata parameter.
