Victor Julien db0f9ddc69 files/tx: inspection, logging and loop optimizations 
Introduce AppLayerTxData::file_tx as direction(s) indicator for transactions.
When set to 0, its not a file tx and it will not be considered for file
inspection, logging and housekeeping tasks.

Various tx loop optimizations in housekeeping and output.

Update the "file capable" app-layers to set the fields based on their
directional file support as well as on the traffic.

Victor Julien 79499e4769 app-layer: move files into transactions 
Update APIs to store files in transactions instead of the per flow state.

Goal is to avoid the overhead of matching up files and transactions in
cases where there are many of both.

Update all protocol implementations to support this.

Update file logging logic to account for having files in transactions. Instead
of it acting separately on file containers, it is now tied into the
transaction logging.

Update the filestore keyword to consider a match if filestore output not
enabled.

Jason Ish f92708b8ca rust/frames: derive direction from StreamSlice 
On the Rust side, a Frame requires a StreamSlice to be created. We can
derive the direction from the StreamSlice removing the need for callers
to provide the direction when operating on the frame.
 4 years ago
Jason Ish 7b11b4d3a1 app-layer: more generic state trait 
Instead of a method that is required to return a slice of transactions,
use 2 methods, one to return the number of transactions in the
collection, and another to get a transaction by its index in the
collection.

This allows for the transaction collection to not be a contiguous array
and instead can be a VecDeque, or possibly another collection type that
supports retrieval by index.

Sam Muhammed 3a490fb16c nfs: Implement frames 
Feature #4872

Frames:
  - RPC Frames: Generic over TCP/UDP
     - rpc.pdu
     - rpc.hdr
     - rpc.data
     - rpc.creds -- for rpc calls

  - NFSv2, NFSv3
     - nfs.pdu
     - nfs.status -- for nfs responses

  - NFSv4 Only Frames
     - nfs4.pdu
     - nfs4.hdr
     - nfs4.ops -- for compound request/response operations
     - nfs4.status -- for nfs4 responses

RPC tcp/udp frames created with separate registeration functions e.g:
add_rpc_tcp_tc_frames()
add_rpc_udp_tc_frames()

Victor Julien 07b1100713 nfs: clean up partial record handling 
There should be no remaining data after parsing the partial
RPC record, so don't handle it but instead add a debug validation
bug on.

Successful processing for NFSv3 read/write records returns
AppLayerResult::ok() directly as all data is consumed.

Jason Ish 7732efbec2 app-layer: include decoder events in app-layer tx data 
As most parsers use an events structure we can include it in the
tx_data structure to reduce some boilerplate/housekeeping code
in app-layer parsers.

Jason Ish 9c67c634c1 app-layer: include DetectEngineState in AppLayerTxData 
Every transaction has an existing mandatory field, tx_data. As
DetectEngineState is also mandatory, include it in tx_data.

This allows us to remove the boilerplate every app-layer has
for managing detect engine state.

Victor Julien 67759795c6 nfs: don't reuse file transactions 
After a file has been closed (CLOSE, COMMIT command or EOF/SYNC part of
READ/WRITE data block) mark it as such so that new file commands on that
file do not reuse the transaction.

When a file transfer is completed it will be flagged as such and not be
found anymore by the NFSState::get_file_tx_by_handle() method. This forces
a new transaction to be created.

Jason Ish 363b5f99c3 rust: functions that reference raw pointers are unsafe 
Based on the Rust clippy lint that recommends that any public
function that dereferences a raw pointer, mark all FFI functions
that reference raw pointers with build_slice and cast_pointer
as unsafe.

This commits starts by removing the unsafe wrapper inside
the build_slice and cast_pointer macros then marks all
functions that use these macros as unsafe.

Then fix all not_unsafe_ptr_arg_deref warnings from clippy.

Fixes clippy lint:

Jason Ish 53413f2d7a rust: remove all usage of transmute 
All cases of our transmute can be replaced with more idiomatic
solutions and do no require the power of transmute.

When returning an object to C for life-time management, use
Box::into_raw to convert the boxed object to pointer and use
Box::from_raw to convert back.

For cases where we're just returning a pointer to Rust managed
data, use a cast.
