ad27615760 Netlink: attribute validation before parsing
Wanted netlink attributes are defined in a table, specifying
their size and neediness. Removing the long conditions that did the
validation before.

Also parsing IPv4 and IPv6 versions regardless on the IPV6 macro.

9ddbfbddf8 Netlink: Allow more than 256 routing tables.
Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to
allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.

86b4e17001 Nest: Fixes bug in missing cleanup during table removal
When a table is removed during reconfiguration, a reference was not
cleared in the old configuration, which breaks undo.

9b9a7143c4 Conf: Fixes bug in symbol lookup during reconfiguration
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.

The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.

fe9f1a6ded Initial commit on integrated BIRD
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

338f85ca77 IO: Handle fd values too big for select()
If the number of sockets is too much for select(), we should at least
handle it with proper error messages and reject new sockets instead of
breaking the event loop.

Thanks to Alexander V. Chernikov for the patch.

8465dccb06 Major RIP redesign
The new RIP implementation fixes plenty of old bugs and also adds support
for many new features: ECMP support, link state support, BFD support,
configurable split horizon and more. Most options are now per-interface.

The patch adds suport for specifying route attributes together with

 route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };

86f567e13c Fix minor issue in pipe route propagation
In some circumstances during reconfiguration, routes propagated by pipes
to other tables may hang there even after the primary routes are removed.

There is already a workaround for this issue in the code which removes
these stale routes by flush process when source protocols are shut down.

This patch is a cleaner fix and allows to simplify the flush process

77edab6409 OSPF: Redesign LSA checksumming
New LSA checksumming code separates generic Fletcher-16 and OSPF-specific
code and avoids back and forth endianity conversions, making it much more
readable and also several times faster.

30d09eb96e OSPF: Fixes validation of LSA checksums
Prior to this patch, BIRD validates the OSPF LSA checksum by calculating
a new checksum and comparing it with the checksum in the header. Due to
the specifics of the Fletcher checksum used in OSPF, this is not
necessarily correct as the checkbytes in the header may be calculated via
a different means and end up with a different value that is nonetheless
still correct.

The documented means of validating the checksum as specified in RFC 905
B.4 is to calculate c0 and c1 from the unchanged contents of the packet,
which must result in a zero value to be considered valid.

Thanks to Chris Boot for the patch.
