To ensure that all calls to cargo use the same environment variables,
put the environment variables in CARGO_ENV so every call to cargo can
easily use the same vars.
The Cargo build system is smarter than make, it can detect a change in
an environment variable that affects the build, and the setting of
SURICATA_LUA_SYS_HEADER_DST changing could cause a rebuild.
Also update suricata-lua-sys, which is smarter about copying headers. It
will only copy if the destination does not exist, or the source header
is newer than the target, which can also prevent unnecessary rebuilds.
This is mainly to fix an issue where subsequent builds may fail,
especially when running an editor with a LSP enabled:
Update lua crate to 0.1.0-alpha.5. This update will force a rewrite of
the headers if the env var SURICATA_LUA_SYS_HEADER_DST changes. This
fixes the issue where the headers may not be written.
The cause is that Rust dependencies are cached, and if your editor is
using rust-analyzer, it might cache the build without this var being
set, so these headers are not available to Suricata. This crate update
forces the re-run of the Lua build.rs if this env var changes, fixing
this issue.
Generic ssn2vec_map was a HashMap used for mapping session key to
different types of vector data:
- GUID
- filename
- share name
Turn this into a bounded LruCache. Rename to ssn2vec_cache.
Size of the cache is 512 by default, and can be configured using:
`app-layer.protocols.smb.max-session-cache-size`
Ticket: #5672.
Reimplement the ssnguid2vec_map HashMap as a LruCache.
Since this is a DCERPC record cache, name it as such.
Default size is 128. Can be controlled by
`app-layer.protocols.smb.max-dcerpc-frag-cache-size`.
Ticket: #5672.
Turn the map mapping the smb session key to smb tree into a lru cache,
limited to 1024 by default.
Add `app-layer.protocols.smb.max-tree-cache-size` option to control the
limit.
Ticket: #5672.
Don't tag the session as gap'd when the GAP is in a precise location:
1. in "skip" data, where the GAP just fits the skip data
2. in file data, where we pass the GAP on to the file
This reduces load of GAP post-processing that is unnecessary in these
case.
This crate lets us instruct it where to copy the header files instead
of our Makefile trying to find the correct ones and copying them into
place.
Can prevent the simultaneous copy errors sometimes seen on a make
without a clean.
Introduce a common function for mapping names to IDs that performs
bounds checking.
Note: For event IDs in the enum that are larger than a uint8_t, -1
will be returned instead of -4. -4 has special meaning during
signature parsin that means requirements were not met. -4 has no
special handling prior to requirements, or the meaning has been lost.
Add a pure rust base64 decoder. This supports 3 modes of operation just
like the C decoder as follows.
1. RFC 2045
2. RFC 4648
3. Strict
One notable change is that "strict" mode is carried out by the rust
base64 crate instead of native Rust. This crate was already used for
encoding in a few places like datasets of string type. As a part of this
mode, now, only the strings that can be reliably converted back are
decoded.
The decoder fn is available to C via FFI.

Ticket 7065
Ticket 7058
According to RFC 3261, a single header can be repeated one or more times,
and its name can also be specified using the 'compact form.'
This patch updates the hashmap used for storing headers to accommodate multiple
values instead of just one.
Additionally, if a header name is defined in the compact form, it is expanded
into its long form (i.e., the standard name).
This conversion simplifies the logic for matching a given header
and ensures 1:1 parity with keywords.
Ticket #6374
Once we are tracking tx progress per-direction for PGSQL, we can trigger
the raw stream reassembly, for detection purposes, as soon as the
transactions are completed in the given direction.
Task #7000
PGSQL's current implementation tracks the transaction progress without
taking into consideration flow direction, and also has indirections
that make it harder to understand how the progress is tracked, as well
as when a request or response is actually complete.
This patch introduces tracking such progress per direction and adds
completion status per direction, too. This will help when triggering
raw stream reassembly or for unidirectional transactions, and may be
useful when we implement sub-protocols that can have multiple requests
per transaction, as well.
CancelRequests and TerminationRequests are examples of unidirectional
transactions. There won't be any responses to those requests, so we can
also mark the response side as done, and set their transactions as
completed.
