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.
- The script-layer 'pkt_hdr' type is extended with a new 'ip6' field
representing the full IPv6 header chain.
- The 'new_packet' event is now raised for IPv6 packets (addresses #523)
- A new event called 'ipv6_ext_header' is raised for any IPv6 packet
containing extension headers.
- A new event called 'esp_packet' is raised for any packets using ESP
('new_packet' and 'ipv6_ext_header' events provide connection info,
but that info can't be provided here since the upper-layer payload
is encrypted).
- The 'unknown_protocol' weird is now raised more reliably when Bro
sees a transport protocol or IPv6 extension header it can't handle.
(addresses #522)
Still need to do IPv6 fragment reassembly and needs more testing.
Also replaced the --snaplen/-l command line option with a
scripting-layer option called "snaplen" (which can also be
redefined on the command line, e.g. `bro -i eth0 snaplen=65535`).
- Reorganize top-level 'doc' Makefile target so submodules can easily
add their own doc-generating routines to it. e.g. the Bro project
makes a placeholder 'doc' target, then adds 'restdoc', 'sphinxdoc';
later Broccoli can add it's own target as a dependency for generating
API docs.
- Fixed generated docs for BIFs not being organized under a base/
subdirectory like the original source files.
- Fixed documentation style for function parameters not applying to
functions declared as record fields.
- Misc. script documentation tweaks to address warnings given by Sphinx.
- bro.init was renamed to base/init-bare.bro and base/all.bro
was renamed to init-default.bro.
- To run in "bare mode" with only the init-bare.bro and no other
scripts from base/, use either -b or --bare-mode.
- The environment variable to run in "bare mode" has been removed.
