version:
EXPORT <filter-spec> for outbound routes (i.e., those announced
by BIRD to the rest of the world).
IMPORT <filter-spec> for inbound routes (i.e., those imported
by BIRD from the rest of the world).
where <filter-spec> is one of:
ALL pass all routes
NONE drop all routes
FILTER <name> use named filter
FILTER { <filter> } use explicitly defined filter
For all protocols, the default is IMPORT ALL, EXPORT NONE. This includes
the kernel protocol, so that you need to add EXPORT ALL to get the previous
configuration of kernel syncer (as usually, see doc/bird.conf.example for
a bird.conf example :)).

o Changed parameters of f_run. Changed rtein+rteout pair to rte pointer
passed by reference, added ea_list of temporary attrs again passed
by reference and finally added a pointer to memory pool for storing
temporary data (new ea_lists's, temporary rta's etc.).
o Re-ordered result codes, so that all accepts come before all rejects.
o Introduced FILTER_ACCEPT and FILTER_REJECT dummy values (will be
used in protocol configurations).
o Added filter_name() which returns name of a filter or ACCEPT/REJECT
for the dummies.

approximation of a integral fraction of page size even if both malloc
overhead and chunk header space is counted.

o Now compatible with filtering.
o Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS
systems (on the others it's impossible to get it semantically correct).
o Learning now stores all of its routes in a separate fib and selects
the ones the kernel really uses for forwarding packets.
o Better treatment of CONFIG_AUTO_ROUTES ports.
o Lots of internal changes.

whitespace/semicolon rules for whole config file:
o All non-zero amounts of whitespace are equivalent to single space
(aka `all the whitespace has been born equal' ;-)).
o Comments count as whitespace.
o Whitespace has no syntactic signifance (it can only separate lexical
elements).
o Consequence: line ends are no longer treated as `;'s.
o Every declaration must be terminated by an explicit `;' unless
or by a group enclosed in `{' and `}'.

documented the remaining ones (sysdep/cf/README).
Available configurations:
o linux-20: Old Linux interface via /proc/net/route (selected by default
on pre-2.1 kernels).
o linux-21: Old Linux interface, but device routes handled by the
kernel (selected by default for 2.1 and newer kernels).
o linux-22: Linux with Netlink (I play with it a lot yet, so it isn't
a default).
o linux-ipv6: Prototype config for IPv6 on Linux. Not functional yet.

i.e. struct proto now contains field 'table' pointing to routing table
the protocol is attached to. Use this instead of &master_table.
Modified all protocols except the kernel syncer to use this field.
|
|
o Nothing is configured automatically. You _need_ to specify
the kernel syncer in config file in order to get it started.
o Syncing has been split to route syncer (protocol "Kernel") and
interface syncer (protocol "Device"), device routes are generated
by protocol "Direct" (now can exist in multiple instances, so that
it will be possible to feed different device routes to different
routing tables once multiple tables get supported).
See doc/bird.conf.example for a living example of these shiny features.

o Introduced struct filter which serves as an external reference
to filter. Using struct symbol for this is unwise since it doesn't
allow extra information attached to the filter and it also forces
all filters to be named.
o Implemented config rule 'filter' which matches either named filter
or an embedded unnamed filter (`{ <filter> }').
o Fixed totally bogus comment at the top of filter.h.
o Added a missing prototype for f_run() to filter.h.

(via Netlink). Tweaked kernel synchronization rules a bit. Discovered
locking bug in kernel Netlink :-)
Future plans: Hunt all the bugs and solve all the FIXME's.
|

To build BIRD with Netlink support, just configure it with
./configure --with-sysconfig=linux-21
After it will be tested well enough, I'll probably make it a default
for 2.2 kernels (and rename it to linux-22 :)).

over EFence and also hopefully smaller memory overhead, but sadly it's non-free
for commercial use).
If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'
checks by default.
Also introduced mb_allocz() for cleared mb_alloc().
