by making tx parsing and creation more easily available,
without needing a dns state.
Dns event NotResponse is now set on the right tx, and not the one
before.
Also debug log for Z-flag on request says "request" instead of
"response"
Also rustfmt dns.rs
This implementation adds types and filters specified in the LDAP RFC to
work with the ldap_parser.
Although using the parser directly would be
best, strange behavior has been observed during transaction logging.
It appears that C pointers are being overwritten, leading to incorrect
output when LDAP fields are logged.

On the way, convert some keywords to use the first-class integer
support.
And helpers for pure rust the support for multi-buffer.
Move the C unit tests about keyword mqtt.protocol_version
to unit tests for generic integer parsing, and test version 5
instead of testing twice version 3.
Also iterate all tx's messages for reason code as is done for other
keywords.
And allow detection on empty topics.
truncate fn is only active and used by dcerpc and smb parsers. In case
stream depth is reached for any side, truncate fn is supposed to set the
tx entity (request/response) in the same direction as complete so the
other side is not forever waiting for data.
However, whether the stream depth is reached is already checked by
AppLayerParserGetStateProgress fn which is called by:
- DetectTx
- DetectEngineInspectBufferGeneric
- AppLayerParserSetTransactionInspectId
- OutputTxLog
- AppLayerParserTransactionsCleanup
and, in such a case, StateGetProgressCompletionStatus is returned for
the respective direction. This fn following efc9a7a, always returns 1
as long as the direction is valid meaning that the progress for the
current direction is marked complete. So, there is no need for the additional
callback to mark the entities as done in case of depth or a gap.
Remove all such glue code and callbacks for truncate fns.

as its functionality is already covered by the generic code.
This removes APP_LAYER_PARSER_TRUNC_TC and APP_LAYER_PARSER_TRUNC_TS
flags as well as FlowGetDisruptionFlags sets STREAM_DEPTH flag in case
the respective stream depth was reached. This flag tells that whether
all the open files should be truncated or not.

DNS v3 logging fixes the discrepancies between request and response
logging with the main difference being queries always being placed in an
array.
Bug: #6281
V3 style DNS logging fixes the discrepancies between request and
response logging better dns records and alert records.
The main change is that queries and answers are always logged as
arrays, and header fields are not logged in array items.
For alerts this means that answers are now logged as arrays, queries
already were.
DNS records will get this new format as well, but with a configuration
parameter.

Add DNSRData OPT type to lua.rs match.

Add additionals to DNSMessage struct.
Add parsing logic to populate additional section data.
Patch dns tests to account for additional section parsing.
Don't assume the ntlmssp version field is always present if the flag is
set. Instead keep track of the offsets of the data of the various blobs
and see if there is space for the version.
Inspired by how Wireshark does the parsing.

To avoid ambiguity, a single definition for base 64 decoding modes will
be used. The Rust base64 transform contains the definitions for the
existing mode types: Strict, RFC2045, RFC4648

This can happen with keyword filestore:both,flow
If one direction does not have a signature group with a filestore,
the file is set to nostore on opening, until a signature in
the other direction tries to set it to store.
Subsequent files will be stored in both directions as flow flags
are now set.
New warning from rustc.
The other option is to allow dead code, however this is more explicit,
and when they are read, its obvious they should be renamed.

On the way, convert unit test DetectSNMPCommunityTest to a SV test.
And also, make snmp.pdu_type use a generic uint32 for detection,
allowing operators, instead of just equality.
Implement special "isset" and "isnotset" modes.
"isset" matches if an IP address is part of an iprep category with any
value.
It is internally implemented as ">=,0", which should always be true if
there is a value to evaluate, as valid reputation values are 0-127.
"isnotset" matches if an IP address is not part of an iprep category.
Internally it is implemented outside the uint support.

For TCP streams, app proto stream reassembly can start earlier, instead

Previously, it was looked for message in plain text, and base64
encoding was only handled for attachments.
This commit also fixes the buffering got such base64 data streamed
into urls finding, by buffering a beginning non-empty line,
and by ensuring that we run extraction on the last line,
even if it had no EOL.
Expose the raw stream earlier to the detection engine, as Pgsql can have
multiple messages per transaction and usually will have a message
complete within one TCP packet.

Bug #7026
Before, the JsonBuilder object for the pgsql event was being created
from the C-side function that actually called the Rust logger.
This resulted that if another module - such as the Json Alert called the
PGSQL logger, we wouldn't have the `pgsql` key present in the log output
- only its inner fields.

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
created during a normal "make".
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.

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

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.

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.
