2017-12-07Nest: Maintain separate IPv4, IPv6 and LLv6 preferred addressesOndrej Zajicek (work)
Also redesign preferred address selection and update protocols to use appropriate preferred address. Based on a previous work by Jan Maria Matejka.
2017-09-06Basic VRF supportOndrej Zajicek (work)
Add basic VRF (virtual routing and forwarding) support. Protocols can be associated with VRFs, such protocols will be restricted to interfaces assigned to the VRF (as reported by Linux kernel) and will use sockets bound to the VRF. E.g., different multihop BGP instances can use diffent kernel routing tables to handle BGP TCP connections. The VRF support is preliminary, currently there are several limitations: - Recent Linux kernels (4.11) do not handle correctly sockets bound to interaces that are part of VRF, so most protocols other than multihop BGP do not work. This will be fixed by future kernel versions. - Neighbor cache ignores VRFs. Breaks config with the same prefix on local interfaces in different VRFs. Not much problem as single hop protocols do not work anyways. - Olock code ignores VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. - Incoming BGP connections are not dispatched according to VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. Perhaps we would need some kernel API to read VRF of incoming connection? Or probably use multiple listening sockets in int-new branch. - We should handle master VRF interface up/down events and perhaps disable associated protocols when VRF goes down. Or at least disable associated interfaces. - Also we should check if the master iface is really VRF iface and not some other kind of master iface. - BFD session request dispatch should be aware of VRFs. - Perhaps kernel protocol should read default kernel table ID from VRF iface so it is not necessary to configure it. - Perhaps we should have per-VRF default table.
2017-09-05KRT: Fix IPv6 ECMP handling with Linux 4.11+Ondrej Zajicek (work)
Starting from Linux 4.11, IPv6 ECMP routes are now notified using RTA_MULTIPATH, like IPv4 ones. The patch adds support for RTA_MULTIPATH parsing for IPv6 routes. This also enables to parse ECMP alien routes correctly. Thanks to Vincent Bernat for the original patch.
2017-07-04Implement onlink flag for nexthopsOndrej Zajicek (work)
Add proper support for per-nexthop onlink flag in routes to handle next hop addresses that are not covered by interface IP ranges. Supported by kernel and static protocols. Thanks to Vincent Bernat for the idea.

2016-12-22Netlink: MPLS routes in kernelJan Moskyto Matejka
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.
2016-12-22Removing (struct rta)->cast. Never used.Jan Moskyto Matejka
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
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.

2016-11-01Build: switch on -Wextra, get rid of most of the warningsJan Moskyto Matejka
There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-09-29Kernel socket missing err_hook fixJan Moskyto Matejka
Thanks to Tim Weippert for bugreport.
2016-09-19KRT: Add krt_scope attributeOndrej Zajicek (work)
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.
2016-09-15KRT: Add kernel metric protocol optionOndrej Zajicek (work)
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.
2016-09-14KRT: Support for IPv6 ECMPOndrej Zajicek (work)
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.
2016-08-30KRT: Forbid path merging on BSDOndrej Zajicek (work)
We support ECMP routes only on Linux. Exported routes are checked in krt_capable(), but a route generated during path merging avoids this check.
2016-07-20Netlink: Fix build with older headers missing IFA_FLAGSOndrej Zajicek (work)
2016-07-20Netlink: Ignore tentative addressesOndrej Zajicek (work)
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
2016-05-17IO: Minor changes in socket AF handingOndrej Zajicek (work)
AF can be specified implicitly by saddr or daddr, flags SKF_V4ONLY and SKF_V6ONLY are to be removed.

2016-05-10netlink: update struct msghdrStijn Tintel
The netlink code assumes an order for the members of struct msghdr. This breaks recvmsg and sendmsg with musl libc on mips64. Fix this by using designated initializers instead. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

2016-05-10Build system reworked to one global Makefile with includes and no nestingJan Moskyto Matejka
Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.
2016-04-13BSD: Add the IPsec SA/SP database entries controlOndrej Zajicek (work)
Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are handled automatically on both Linux and FreeBSD. Based on patches from Pavel Tvrdik.
