Philippe Antoine 862e84877f ssl: first pass limit when allocating buffer for certificates 
With this check, on the first packet of a certificate presenting
a length of 16Mbytes, we only allocate up to 65Kb

When we get to the point where need more than 65Kb, we realloc
to the true size.

With this check, it makes it more expensive for an attacket to use
this allocation as a way to trigger ressource exhaustion...

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()

Jason Ish 1e65324940 smb: rules for messages in the wrong direction 3 years ago
Jason Ish 2341f47755 smb: handle records in the wrong direction 
If an SMB record is seen in the wrong direction, set an event on the PDU
frame and don't process the record in the state.

No error is returned, so the next record will be processed.

Jason Ish 09e2d3b216 smb: expose smb1 request/reply flags with a method

Jason Ish 7b659489c8 smb: fix smb2 header flag parsing 
The bits were being parsed in the order they're displayed in Wireshark,
rather than the order they were being seen on the wire, resulting in
direction and async being 0 more often than they should be.

Instead of bits, take the 4 bytes as an le_u32 and just use bit masks to
extract what we need into a struct, I think its easier to reason about
this way when comparing to the Microsoft documentation.

used.

Philippe Antoine 3fd8e908f8 range: better closing for out of order ranges 
Ticket: 5132

In case of a duplicate range, we can return early, because
there is no new data to process.

More importantly, this commit adds a check about wether the file
got closed meanwhile, so that this just completed out of order
range, even if it brings new data, is now irrelevant.
This can happen for instance if there was a gap...
