Pascal Delalande 80f2fbac6e rust/tftp: eve logging with rust 8 years ago
Clement Galland b9cf49e933 rust/tftp: add tftp parsing and logging 
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"}

Victor Julien e8939335ea rust/nfs: explicitly handle GAPs from C 
It seems that Rust optimizes this code in such a way that it
passes the null ptr along as real data.

Victor Julien 2c3c8f8b85 rust/filetracker: if file API return error, trunc file 8 years ago
Victor Julien d27ed5957f rust/nfs: fix read reply handling 
READ replies with large data chunks are processed partially to avoid
queuing too much data. When the final chunk was received however, the
start of the chunk would already tag the transaction as 'done'. The
more aggressive tx freeing that was recently merged would cause this
tx to be freed before the rest of the in-progress chunk was done.

This patch delays the tagging of the tx until the final data has been
received.

Victor Julien 45c5030ff0 rust/file: change return type for FileOpenFileWithId 
Make it int so we can easily check it in Rust. No consumer used the
File pointer that was returned before anyway.

Victor Julien bca0cd71ae app-layer: use logger bits to avoid looping 
Avoid looping in transaction output.

and retrieve the bits in a single step as well.

Update users of the API.

Eric Leblond b0a6934431 app-layer-ftp: add ftp-data support 
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.

Jason Ish 5a8537fe4a rust/dns - convert more type values to text 
Issue:

Convert more record type and errr code values to text.
Remove duplicate type declarations.

Pierre Chifflier 83808bbdad rust/ntp: convert parser to new registration method 
Converting the NTP parser to the new registration method is a simple,
3-steps process:
- change the extern functions to use generic input parameters (functions
  in all parsers must share common types to be generic) and cast them
- declare the Parser structure
- remove the C code and call the registration function
 8 years ago
Pierre Chifflier e7c0a53cbf rust/applayer: add registration iface for parsers 
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.

Jason Ish 6a4cefb7c5 rust: --enable-rust-strict to turn warnings into errors 8 years ago
Jason Ish 3063851d85 rust/dns/tcp - probe even if payload is short 
As the DNS probe just uses the query portion of a response, don't
require there to be as many bytes as specified in the TCP DNS
header. This can occur in large responses where probe is called
without all the data.

Fixes the cases where the app proto is recorded as failed.

Jason Ish 40991cab82 rust/dns: handle multiple txt strings 
Fix handling of TXT records when there are multiple strings
in a single TXT record. For now, conform to the C implementation
where an answer record is created for each string in a single
txt record.

Also removes the data_len field from the answer entry. In Rust,
the length is available from actual data, which after decoding
may actually be different than the encoded data length, so just
use the length from the actual data.

Jason Ish 717b826d25 rust: safe string handling in logging 
In logging (SCLog*), safely convert strings to cstrings instead
of blindly unwrapping them.

Also implement a simple rust logger if the Suricata C context
is not available.

Jason Ish 829155b9d5 rust/dns: pass byte arrays directly to rust/json 
Using the json.set_string_from_bytes which will
safely convert the bytes printable ascii string
before logging.
 8 years ago
Jason Ish 96cc503026 rust/lua: use lua_pushlstring for strings 
Lua strings can contain NULLs, and Rust strings are UTF8 which
can also contain NULLs. Use pushlstring so a NULL containing
string can be pushed.
 8 years ago
Jason Ish 6dbc5be4be rust/json: only output printable characters 
Rust strings are UTF8 and we cannot yet rely on jansson
having json_stringn on all supported OS distributions yet
so sanitize strings to ascii before printing.

Also add set_string_from_bytes which is like set_string, but
accepts a byte array as input.

Victor Julien 0d79181d78 nfs: rename nfs3 to nfs 
Since the parser now also does nfs2, the name nfs3 became confusing.
As it's still in beta, we can rename so this patch renames all 'nfs3'
logic to simply 'nfs'.

Victor Julien 58af39131f rust/nfs: handle GAPs 
In normal records it will try to continue parsing.

GAP 'data' will be passed to file api as '0's. New call is used
so that the file API does know it is dealing with a GAP. Such
files are flagged as truncated at the end of the file and no
checksums are calculated.

Initial version of a filetracker API that depends on the filecontainer

Victor Julien a809f090d3 rust: filecontainer API 
Wrapper around Suricata's File and FileContainer API. Built around

things.

Jason Ish 94032d3ada rust: wrapper around C logging, and "context"
