Victor Julien 04ccfda639 pcap: implement LINKTYPE_NULL
Implement LINKTYPE_NULL for pcap live and pcap file.

From: http://www.tcpdump.org/linktypes.html

"BSD loopback encapsulation; the link layer header is a 4-byte field,
 in host byte order, containing a PF_ value from socket.h for the
 network-layer protocol of the packet.

 Note that ``host byte order'' is the byte order of the machine on
 which the packets are captured, and the PF_ values are for the OS
 of the machine on which the packets are captured; if a live capture
 is being done, ``host byte order'' is the byte order of the machine
 capturing the packets, and the PF_ values are those of the OS of
 the machine capturing the packets, but if a ``savefile'' is being
 read, the byte order and PF_ values are not necessarily those of
 the machine reading the capture file."

Ken Steele a781fc5c2e Make suricata_ctl_flags be volatile
The global variable suricata_ctl_flags needs to volatile, otherwise the
compiler might not cause the variable to be read every time because it
doesn't know other threads might write the variable.

This was causing Suricata to not exit under some conditions.

Victor Julien b5d3b7e92a Fix pcap packet acquisition methods
Fix pcap packet acquisition methods passing 0 to pcap_dispatch.
Previously they passed the packet pool size, but the packet_q_len
variable was now hardcoded at 0.

This patch sets packet_q_len to 64. If packet pool is empty, we fall
back to direct alloc. As the pcap_dispatch function is only called
when packet pool is not empty, we alloc at most 63 packets.

Ken Steele 3c6e01f653 Replace ringbuffer in Packet Pool with a stack for better cache locality
Using a stack for free Packet storage causes recently freed Packets to be
reused quickly, while there is more likelihood of the data still being in
cache.

The new structure has a per-thread private stack for allocating Packets
which does not need any locking. Since Packets can be freed by any thread,
there is a second stack (return stack) for freeing packets by other threads.
The return stack is protected by a mutex. Packets are moved from the return
stack to the private stack when the private stack is empty.

Returning packets back to their "home" stack keeps the stacks from getting out
of balance.

The PacketPoolInit() function is now called by each thread that will be
allocating packets. Each thread allocates max_pending_packets, which is a
change from before, where that was the total number of packets across all
threads.

Victor Julien f7b1aefaf4 Bug 1107: decoders: bail out on pseudo packets
Flow-timeout code injects pseudo packets into the decoders, leading
to various issues. For a full explanation, see:
  https://redmine.openinfosecfoundation.org/issues/1107

This patch works around the issues with a hack. It adds a check to
each of the decoder entry points to bail out as soon as a pseudo
packet from the flow timeout is encountered.

Eric Leblond 1bdc39fe9b cmdline: add -k to specify checksum validation
This patch adds a '-k' option to suricata to be able to specify
the checksum validation to use. If '-k all' is used, checksum
validation is forced. If '-k none' is used, no checksum validation
is made.

Message output in case of detection of a pcap file with a probable
cheksum issue has been updated to indicate that '-k' is a solution.

Eric Leblond 8b5be26f49 pcap-file: add checksum-checks configuration variable
This patch adds support for checksum-checks in the pcap-file running
mode. This is the same functionnality as the one already existing for
live interface.

It can be setup in the YAML:
  pcap-file:
    checksum-checks: auto

A message is displayed for small pcap to warn that invalid checksum
rate is big on the pcap file and that checksum-check could
be set to no.

Eric Leblond 3088b6ac34 Add invalid pkt counter.
This patch adds and increments a invalid packet counter. It

Eric Leblond d4b7ecfbe3 decode: update API to return error
In some cases, the decoding is not possible and some really invalid
packet can be created. This is in particular the case of tunnel. In
that case, it is more interesting to forget about the tunneled
packet and only consider the original packet.

DecodeTunnel function is maked as warn_unused_result because it is
meaningful for the decoder to know if the underlying data were not
correct. And in this case, only focus detection on the content.

Eric Leblond 5b067e1abb pcap-file: treat the case of unsupported pcap link

Eric Leblond f8921d8a28 unix-socket: introduce API to add commands and tasks
This patch transforms the unix socket into a flexible system to
add commands (triggered by user) and taks (run periodically).
It introduces two functions UnixManagerRegisterCommand and
UnixManagerRegisterBackroundTask to registed commands and tasks.

Other part of Suricata can then declare a new command via a simple
call of the function. In the case of a command the caller is
responsible of building the answer message using Jansson API. The
sending of the message is made by unix manager code.

Eric Leblond 20a8b9dbe5 unix-manager: add unix command socket and associated script
This patch introduces a unix command socket. JSON formatted messages
can be exchanged between suricata and a program connecting to a
dedicated socket.
The protocol is the following:
 * Client connects to the socket
 * It sends a version message: { "version": "$VERSION_ID" }
 * Server answers with { "return": "OK|NOK" }
If server returns OK, the client is now allowed to send command.

The format of command is the following:
 {
   "command": "pcap-file",
   "arguments": { "filename": "smtp-clean.pcap", "output-dir": "/tmp/out" }
 }
The server will try to execute the "command" specified with the
(optional) provided "arguments".
The answer by server is the following:
 {
   "return": "OK|NOK",
   "message": JSON_OBJECT or information string
 }

A simple script is provided and is available under scripts/suricatasc. It
is not intended to be enterprise-grade tool but it is more a proof of
concept/example code.  The first command line argument of suricatasc is
used to specify the socket to connect to.

Configuration of the feature is made in the YAML under the 'unix-command'
section:
  unix-command:
    enabled: yes
    filename: custom.socket
The path specified in 'filename' is not absolute and is relative to the
state directory.

A new running mode called 'unix-socket' is also added.
When starting in this mode, only a unix socket manager
is started. When it receives a 'pcap-file' command, the manager
start a 'pcap-file' running mode which does not really leave at
the end of file but simply exit. The manager is then able to start
a new running mode with a new file.

To start this mode, Suricata must be started with the --unix-socket
 option which has an optional argument which fix the file name of the
socket. The path is not absolute and is relative to the state directory.

THe 'pcap-file' command adds a file to the list of files to treat.
For each pcap file, a pcap file running mode is started and the output
directory is changed to what specified in the command. The running
mode specified in the 'runmode' YAML setting is used to select which
running mode must be use for the pcap file treatment.

This requires modification in suricata.c file where initialisation code
is now conditional to the fact 'unix-socket' mode is not used.

Two other commands exists to get info on the remaining tasks:
 * pcap-file-number: return the number of files in the waiting queue
 * pcap-file-list: return the list of waiting files
'pcap-file-list' returns a structured object as message. The
structure is the following:
 {
  'count': 2,
  'files': ['file1.pcap', 'file2.pcap']
 }

we are in an unlikely case. This patch adds the unlikely()
expression to indicate this to gcc.

is the following:

Victor Julien 820b0ded82 Add per packet profiling.
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv
