Don't treat 'external' parsers as more experimental. All parsers
depend on crates to some extend, and all have C glue code. So the
distinction doesn't really make sense.
Add a new parser for Internet Key Exchange version (IKEv2), defined in
RFC 7296.
The IKEv2 parser itself is external. The embedded code includes the
parser state and associated variables, the state machine, and the
detection code.
The parser looks the first two messages of a connection, and analyzes
the client and server proposals to check the cryptographic parameters.
Implement SMB app-layer parser for SMB1/2/3. Features:
- file extraction
- eve logging
- existing dce keyword support
- smb_share/smb_named_pipe keyword support (stickybuffers)
- auth meta data extraction (ntlmssp, kerberos5)
TFTP parsing and logging written in Rust.
Log on eve.json the type of request (read or write), the name of the file and
the mode.
Example of output:
"tftp":{"packet":"read","file":"rfc1350.txt","mode":"octet"}
Use expectation to be able to identify connections that are
ftp data. It parses the PASV response, STOR message and the
RETR message to provide extraction of files.
Implementation in Rust of FTP messages parsing is available.
Also this patch changes some var name prefixed by ssh to ftp.
Add Rust support for the common interface to declare and register all
parsers.
Add a common structure definition to contain all required elements
required for registering a parser, similar to the C interface.
This also reduces the risk of incorrectly registering a parser: the
compiler prevents omitting required functions from the structure, and
functions (even if external) are type-checked. Optional functions are
explicitly marked.
Initial version of a filetracker API that depends on the filecontainer
and wraps around the Suricata File API in C.
The API expects chunk based transfers where chunks can be out of order.
Wrapper around Suricata's File and FileContainer API. Built around
assumption that a rust owned structure will have a
'SuricataFileContainer' member that is managed by the C-side of
things.
Where the context is a struct passed from C with pointers
to all the functions that may be called.
Instead of referencing C functions directly, wrap them
in function pointers so pure Rust unit tests can still run.
