Jason Ish f5a90e26a9 rust: for sclog*, strip nul bytes before logging 8 years ago
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 1ebad6bd71 rust/dns: cargo unit test prototype 
Do remove compiler warning when building without unit tests.

Jason Ish 14951e3f00 rust: save cargo and CARGO_HOME to variables 
During configure, substitute the path of cargo, as well as the
value of CARGO_HOME as variables. This fixes the case where a
user might do:
  make
  sudo make install
Which will cause the cargo bits to be rebuilt, including
re-downloading external crates.

By saving these to variables we can be sure that the same
values are used during make install as were used during
make which prevents the Rust artifacts from being rebuild
during "sudo make install".

Eric Leblond 4be031394b output-json-alert: fallback to payload if stream is void 
If stream logging results in no data then we fallback to payload
data to get somethingi that could be interesting  instead of
nothing.

with a 0 to avoid problem when calling strlen().

Victor Julien d61fa0c43c tunnel: refactor tunnel verdict handling 
Observed:

STARTTLS creates 2 pseudo packets which are tied to a real packet.
TPR (tunnel packet ref) counter increased to 2.

Pseudo 1: goes through 'verdict', increments 'ready to verdict' to 1.
Packet pool return code frees this packet and decrements TPR in root
to 1. RTV counter not changed. So both are now 1.

Pseudo 2: verdict code sees RTV == TPR, so verdict is set based on
pseudo packet. This is too soon. Packet pool return code frees this
packet and decrements TPR in root to 0.

Real packet: TRP is 0 so set verdict on this packet. As verdict was
already set, NFQ reports an issue.

The decrementing of TPR doesn't seem to make sense as RTV is not
updated.

Solution:

This patch refactors the ref count and verdict count logic. The beef
is now handled in the generic function TmqhOutputPacketpool(). NFQ
and IPFW call a utility function VerdictTunnelPacket to see if they
need to verdict a packet.

Remove some unused macro's for managing these counters.

Victor Julien 7c119cc595 nfs: log number of chunks that xfer'd a file 8 years ago
Victor Julien ed706583e9 nfs: add nfs to alerts

applies to all app-layers.

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.

Jason Ish 6bddc4d3e0 python: use python path found during configure

executable.

Eric Leblond 26eb49d721 bypass: add explicit flag in stream engine 
TCP reassembly is now deactivated more frequently and triggering a
bypass on it is resulting in missing some alerts due forgetting
about packet based signature.

So this patch is introducing a dedicated flag that can be set in
the app layer and transmitted in the streaming to trigger bypass.

It is currently used by the SSL app layer to trigger bypass when
the stream becomes encrypted.

Jason Ish f1ba406d39 travis: add rust 1.7.0 build

Jason Ish 26914cd59a rust/dns: copy over dns unit tests 
Only the tests that make sense were copied over, those testing
correlation of responses to requests were not.

Also, remove compiler warning when not built with
unit tests.

Jason Ish fafa75035f rust: don't fail distcheck if cargo-vendor not found 
Allow distcheck to pass if cargo vendor is not found by not
failing out. It is not required to successfully build a dist
tarball, the Rust sources will just not be vendored in.

Also don't fail out make dist if Python is not installed. A build
will still be successful is Python is available on the end
build system.
