Remove maintainer-clean-local, this is not needed.
In distclean-local, remove "rust/dist" and "rust/vendor" as they are
created during "make dist".
In "clean-local", remove "rust/target" and "rust/gen" as they are

So far, the SANs were available as a part of IssuerDN via x509_parser
crate but SANs were not available to the SSLState* to be directly used
to setup and match against a sticky buffer.
Expose it to SSLStateConnp.

Addresses this warning from the Rust compiler:
warning: `../rust/.cargo/config` is deprecated in favor of `config.toml`

Done consistently for all protocols
This may change some protocols behaviors which failed early
if they found there was not enough data...
As this triggers rustc 1.78
unsafe precondition(s) violated: slice::from_raw_parts requires
the pointer to be aligned and non-null,
and the total size of the slice not to exceed `isize::MAX`

- Remove no_mangle and pub from FFI functions that are only accessed
with a function pointer.
- Rename all no_mangle FFI functions to our C naming scheme.
This implements a logger for the SDP protocol.
Given that SDP is encapsulated within other protocols (such as SIP),
enabling it separately is not necessary.

Ticket: 6892
As HTTP hpack header compression allows one single byte to
express a previously seen arbitrary-size header block (name+value)
we should avoid to copy the vectors data, but just point
to the same data, while reamining memory safe, even in the case
of later headers eviction from the dybnamic table.
Rust std solution is Rc, and the use of clone, so long as the
data is accessed by only one thread.
It was brought to my attention by GLongo that Pgsql parser handled eof
diffrently for requests and responses, and apparently there isn't a good
reason for such a difference therefore, apply same logic used for
rs_pgsql_parse_request for checking for eof when parsing a response.
Remove the path.lib parameter that is substituted into the output
Cargo.toml by autoconf. Instead, as part of the build, "cd" into the
source directory. We already set the Rust target directory to the
external build directory.
This makes the Cargo.toml more generic, and in a format suitable for
publishing to crates.io. It also makes it easier to pull in external
crates without needing to patch up their Cargo.toml, for example, it
might make pulling libhtp-rs easier.
When outputting a float, check if its infinity, or not a number and
output a null instead.
Using a null was chosen as this is what serde_yaml, Firefox, Chrome,
Node, etc. do.

This permits to detect the SIP protocol using pattern matching instead of
probing parser.
Since it is no longer used, the respective probing functions have been removed.
This patch permits to set a direction when a new transaction is created in order
to avoid 'signature shadowing' as reported by Eric Leblond in commit
5aaf50760f
The `is_version_char` function incorrectly allowed characters that are not
part of the valid SIP version "SIP/2.0".
For instance, 'HTTP/1.1' was mistakenly accepted as a valid SIP version,
although it's not.
This commit fixes the issue by updating the condition to strictly
check for the correct version string.

Instead of just setting the old transactions to a drop state so
that they get later cleaned up by Suricata, fail creating new ones.
This is because one call to app-layer parsing can create many
transactions, and quadratic complexity could happen in one
single app-layer parsing because of find_or_create_tx
If the next PDU is already in the slice next, do not use it and
restrict ourselves to the length of this PDU.
Avoids overconsumption of memory by quadratic complexity, when
having many small PDUS in one big chunk being parsed
Ticket: #6411
Ticket: 5926
HTTP2 continuation frames are defined in RFC 9113.
They allow header blocks to be split over multiple HTTP2 frames.
For Suricata to process correctly these header blocks, it
must do the reassembly of the payload of these HTTP2 frames.
Otherwise, we get incomplete decoding for headers names and/or
values while decoding a single frame.
Design is to add a field to the HTTP2 state, as the RFC states that
these continuation frames form a discrete unit :
> Field blocks MUST be transmitted as a contiguous sequence of frames,
> with no interleaved frames of any other type or from any other stream.
So, we do not have to duplicate this reassembly field per stream id.
Another design choice is to wait for the reassembly to be complete
before doing any decoding, to avoid quadratic complexity on partially
decoding of the data.
Especially sets transactions to complete when we get a response
without having seen the request, so that the transactions
end up getting cleaned (instead of living/leaking in the state).
Also try to set the event on the relevant transaction, instead
of creating a new transaction just for the purpose of having
the event.
Ticket: #6299
Add a new rule keyword "requires" that allows a rule to require specific
Suricata versions and/or Suricata features to be enabled.

requires: version >= 7.0.3 < 8
requires: version >= 7.0.3 < 8 | >= 8.0.3

A CanceldRequest can occur after any query request, and is sent over a
new connection, leading to a new flow. It won't take any reply, but, if
processed by the backend, will lead to an ErrorResponse.
Task #6577
SCDnsTxGetQueryName was introduced to allow for getting the query name
in responses as well as requests, so covers the functionality of
rs_dns_tx_get_query_name.
This sticky buffer will allow content matching on the answer names.
While ansers typically only occur in DNS responses, we allow the buffer
to be used in request context as well as the request message format
allows it.
Feature: #6496
DNS request and response messages follow the same format so there is
no reason not to use the same data structure for each. While its
unlikely to see fields like answers in a request, the message format
does not disallow them, so it might be interesting data to have the
ability to log.
With the changes in the probing_ts function, this other one could become
obsolete. Remove it, and directly call `parser::parse_request` when
checking for gaps, instead.
Some non-pgsql traffic seen by Suricata is mistankenly identified as
pgsql, as the probing function is too generic. Now, if the parser sees
an unknown message type, even if it looks like pgsql, it will fail.
Bug #6080
We had unkonwn message type for the backend, but not the frontend
messages. It's important to better identify those to improve pgsql
probing functions.

This allows, for simple loggers, to have a unique definition

This way, alerts, files, and app-layer event can share the code

* Log vendor client identifier (dhcp option 60) if extended dhcp
logging is turned on. This required the `vendor_client_identifier` to

* Added `requested_ip` to the json schema as well, since it was
missed. My SV test failed without it.

So far, if only the starting request was a DCERPC request, it would be
considered DCERPC traffic. Since ALTER_CONTEXT is a valid request type,
it should be accepted too.

Bug 6191
Ticket: #6211
Completes commit 02dece5db5
Once a http2 stream has end of stream flag, we close the file.
If we see new data frames with this stream id, the new_chunk
function should ignore them as the file was already closed.
We only try to parse a small subset of what is possible in
RFB. Currently we only understand some standard auth schemes
and stop parsing when the server-client handshake is complete.
Since in IPS mode returning an error from the parser causes
drops that are likely uncalled for, we do not want to return
errors when we simply do not understand what happens in the
traffic. This addresses Redmine #5912.
Bug: #5912.
Rust 1.70 appears to now link code on both branches of `if cfg!(test)`
now causing Rust unit tests to fail as that pattern was used to
disable functions only available when linked with the Suricata C code.
To work-around this issue, provide two versions of the `new` function,
one for unit tests and one when running as an application.
and not the one from state
If a SNMP flow starts with a V2 version transaction,
then there is a V3i version transaction,
we will now log V3 for the second transaction
When adding an element to the dynamic headers table, the oldest
ones may get evicted. When multiple elements get evicted, they
should get evicted all at once with drain, instead of one by one
as there will be a massive move each time.
Ticket: #6103
Use try_reserve before growing the internal buffer, and the internal
state vector. This allows allocation errors to be caught and an error
returned instead of just aborting the process.
Ticket: #6057
Use backticks for proper markdown processing. As Rust code in
backticks is compiled, and this is a non-complete example, tag the
code sample to be ignored.
