The patch allows to use autoreconf, replaces some long obsolete
constructs and does some other minor cleanups. Also, the file
configure.in is renamed to configure.ac, as the old name has been
deprecated for a long time.
Thanks to Ruben Kerkhof for the patchset.
FreeBSD 11 changed endianity of ip_len field from host order to network
order. Also DragonFly BSD allegedly expects network order here.
Thanks to Olivier Cochard-Labbé for the patch.
Anyway, Bird is now capable to insert both MPLS routes and MPLS encap
routes into kernel.
It was (among others) needed to define platform-specific AF_MPLS to 28
as this constant has been assigned in the linux kernel.
No support for BSD now, it may be added in the future.
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.
Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).
From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.
- Unit Testing Framework (BirdTest)
- Integration of BirdTest into the BIRD build system
- Tests for several BIRD modules
Based on squashed Pavel Tvrdik's int-test branch, updated for
current int-new branch.
BIRD passed string from configuration to openlog(), which kept it
internally. After reconfiguration the old string was freed, therefore
openlog had invalid copy.
Thanks to Chris Caputo for the original patch.
Add a new route attribute, krt_scope, to expose the Linux kernel route
scope. Constants from /etc/iproute2/rt_scopes (prefixed by "ips_") are
expected to be used with the attribute. Both import and export are
supported.
Also, the patch fixes device route export to the kernel, by setting link
scope automatically.
Kernel protocol calls rt_export_merged(), which used @rte_update_pool for
temporary allocations, supposing it is called from other functions from
rt-table.c that handles locking and flushing of the linpool. Therefore,
linpool was not flushed properly and memory leaked.
Add linpool argument to rt_export_merged() and use @krt_filter_lp when
called from kernel protocol.
Thanks to Justin Cattle and Alexander Frolkin for the bugreport.
(Commit squashed and updated by Ondrej Zajicek)
Kernel routes with different metrics do not clash with each other,
therefore using dedicated metric value is a reliable way to avoid
overwriting routes from other sources (e.g. kernel device routes).
Although kernel route metric could already be set as a route attribute by
filters, that is not consistent with the way how Linux kernel handles
route metric - not just a route attribute, but a part of a route key.
Linux represents IPv6 ECMP routes as a sequence of unipath routes with
the same prefix. We have to translate between our representation (one
route with multipath next hop) and the Linux representation in both
directions.
Proper learning of alien IPv6 ECMP routes still not supported.
Thanks to Mikhail Sennikovskii for the original patch.
Ignore tentative IPv6 addresses and wait until finish of Duplicate
Address Detection (We got notification when an address is no longer
tentative) to avoid problems when protocols try to use interfaces
with tentative link-local addresses.
Based on patch from Jan Moskyto Matejka
