256cd592a7 Improve handling of IPv6 Routing Type 0 headers.
- For RH0 headers with non-zero segments left, a "routing0_segleft"
  flow_weird event is raised (with a destination indicating the last
  address in the routing header), and an "rh0_segleft" event can also
  be handled if the other contents of the packet header are of interest.
  No further analysis is done as the complexity required to correctly
  identify destination endpoints of connections doesn't seem worth it
  as RH0 has been deprecated by RFC 5095.

- For RH0 headers without any segments left, a "routing0_header"
  flow_weird event is raised, but further analysis still occurs
  as normal.

f4101b5265 Improve handling of IPv6 routing type 0 extension headers.
- flow_weird event with name argument value of "routing0_hdr" is raised
  for packets containing an IPv6 routing type 0 header because this
  type of header is now deprecated according to RFC 5095.

- packets with a routing type 0 header and non-zero segments left
  now use the last address in that header in order to associate
  with a connection/flow and for calculating TCP/UDP checksums.

- added a set of IPv4/IPv6 TCP/UDP checksum unit tests

0ceca706f6 Change routing0_data_to_addrs BIF to return vector of addresses.
Because the order of addresses in type 0 routing headers is
interesting/important.

c765f43fe3 Refactor script-layer IPv6 ext. header chain (addresses #795)
This replaces the "ip6_hdr_chain" in the "ip6_hdr" record with a vector of
"ip6_ext_hdr" to make it easier to traverse the chain.

d39a389201 make optional fields possible for input framework.
This do not have to be present in the input file and are marked as &optional in the record description.

Those can e.g. be used to create field values on the file in a predicate while reading a file - example:

	Input::add_table([$source="input.log", $name="input", $idx=Idx, $val=Val, $destination=servers,
				$pred(typ: Input::Event, left: Idx, right: Val) = { right$notb = !right$b; return T; }

1c1d657039 Changes to IPv6 ext. header parsing (addresses #795).
In response to feedback from Robin:

  - rename "ip_hdr" to "ip4_hdr"

  - pkt_hdr$ip6 is now of type "ip6_hdr" instead of "ip6_hdr_chain"

  - "ip6_hdr_chain" no longer contains an "ip6_hdr" field, instead
    it's the other way around, "ip6_hdr" contains an "ip6_hdr_chain"

  - other internal refactoring

57ffe1be77 completely change interface again.
compiles, not really tested.

basic test works 70% of the time, coredumps in the other 30 - but was not easy to debug on a first glance (most interestingly the crash happens in the logging framework - I wonder how that works).
Other tests are not adjusted to the new interface yet.

bf3f184a01 Change IPv6 literal constant syntax to require encasing square brackets
This is to avoid ambiguity between compressed hex notation and
module namespacing, both which use "::". E.g.: "aaaa::bbbb" could
be an identifier or an IPv6 address, but "[aaaa::bbbb]" is now
clearly the address.

Also added IPv6 mixed notation to allow an IPv4 dotted-decimal
address to be specified in the lower 32-bits.

0b32c980bf Update PacketFilter/Discarder code for IP version independence.
The signatures of script-layer functions 'discarder_check_ip',
'discarder_check_tcp', 'discarder_check_udp', and 'discarder_check_icmp'
were changed to use the more general 'pkt_hdr' type as a parameter
instead of individual header types.

fef671e4a6 Fix a BRO_PROFILER_FILE/mkstemp portability issue. (addresses #794) 2012-03-02 12:40:25 -06:00
Jon Siwek
ef5e9caaf4 Changes to how script coverage integrates with test suites.
- BRO_PROFILER_FILE now passes .X* templated filenames to mkstemp
  for generating unique coverage state files.  All test suites
  now use this so each Bro instance writes to a unique coverage file.
- Rearranging Makefile targets.  The general rule is that if the
  all/brief target fails out due to a test failure, then the dependent
  coverage target won't run, but can still be invoked directly later.
  (e.g. make brief || make coverage)
