2021-04-25CI: Fix debian-10-i386 docker fileOndrej Zajicek (work)
2021-04-25Doc: Include full LinuxDocTools codeOndrej Zajicek (work)
BIRD uses hacked LinuxDocTools for building documentation, keeping some parts locally and using remaining parts from system-installed one. This setup breaks when LinuxDocTools makes some internal changes and is hard to keep consistent. Just include full LinuxDocTools code (both hacked and unmodified parts) to avoid consistency issues. Note that we still need some binaries from LinuxDocTools, so it still needs to be installed to build documentation.

2021-04-19Internal route tables have a reduced cleanup routineMaria Matejka
This fixes an internal table cleanup bug introduced in ff397df7edcbe7a8abca5b419729b9c64c063847.
2021-04-19BSD: Fix invalid pointer derefence in logging codeStefan Haller
For logging purposes a stack allocated net_addr struct was passed by value as vararg (instead of the expected pointer). This resulted in a segfault when the specific error condition got logged.
2021-04-12Lib: Fix handling of buffers in timestamp formattingOndrej Zajicek (work)
The code in tm_format_real_time() mixed up two buffers and their sizes, which may cause crash in MRT dumping code. Thanks to Piotr Wydrych for the bugreport.
2021-04-07Unix: Expand accepted ranges of iproute2 constantsOndrej Zajicek (work)
We support 32bit table and realm/flow ids, we should also accept them as constants. Thanks to Patrick Hemmer for the bugreport.
2021-04-03Doc: Fix flowspec exampleOndrej Zajicek (work)
Thanks to Matt Corallo for the bugreport.
2021-03-30Allocation of ea_list in one contiguous memory blockMaria Matejka
This saves some bytes of memory for complex ea's.
2021-03-30Routing table is now a resource allocated from its own poolMaria Matejka
This also fixes memory leaks from import/export tables being never cleaned up and freed.
2021-03-30Resources: added mb_move() to complement rmove() for memory blocksMaria Matejka
2021-03-30Routing tables list iteration should use explicit node struct positionMaria Matejka
2021-03-30BGP: Do not keep BAF_EXT_LEN flag internallyOndrej Zajicek (work)
The flag makes sense just in external representation. It is reset during BGP export, but keeping it internally broke MRT dumps for short attributes that used it anyways. Thanks to Simon Marsh for the bugreport and the patch.
2021-03-25Dropping automatic tests for Debian 7 Wheezy.Maria Matejka
Debian 7 Wheezy has been superseded by Debian 8 Jessie on Apr 25, 2015, with LTS support ending on May 31, 2018. Debian 7 Wheezy's default GCC doesn't fully support C11. It should anyway still be possible to build BIRD for Debian 7 if you backport a C11-capable compiler there.
2021-03-25Slab: head now uses bitmask for used/free nodes info instead of listsMaria Matejka
From now, there are no auxiliary pointers stored in the free slab nodes. This led to strange debugging problems if use-after-free happened in slab-allocated structures, especially if the structure's first member is a next pointer. This also reduces the memory needed by 1 pointer per allocated object. OTOH, we now rely on pages being aligned to their size's multiple, which is quite common anyway.
2021-03-18NEWS and version updatev2.0.8Ondrej Zajicek (work)
2021-03-18Add new BGP testsOndrej Zajicek (work)
2021-03-18BGP: Do not show statisticsOndrej Zajicek (work)
BGP statistics code was preliminary and i wanted to replace it by separate 'show X stats' command. The patch hides the preliminary output in 'show protocols all' so it is not part of the released version.
2021-03-17RPKI: Improve error handling of DNS resolverOndrej Zajicek (work)
2021-03-17Minor fixes for restricted buildsOndrej Zajicek (work)
2021-03-16Pipe: Propagate debug flags from protocol to channelsOndrej Zajicek (work)
Pipe channels are kind-of implicit, so setting protocol debug flags should also set pipe debug flags.
2021-03-16OSPFv3: Update neighbor authentication state from Hello packetsOndrej Zajicek (work)
In OSPFv3, only Hello and DBDes packets contain flags specifying whether RFC 7166 authentication trailer is used. Other packets are processed based on stored authentication state in neighbor structure. Update this state with each received Hello to handle authentication change from reconfigurations. Thanks to Joakim Tjernlund and Kenth Eriksson for the bugreport.
2021-03-15Filter: Update 'gw' to handle IPv6 link-local addressesOndrej Zajicek (work)
When a link-local address is set, use the existing iface for scope. Thanks to Marcel Krüger for the bugreport.
2021-03-15Doc: Document automatic RPKI reloadOndrej Zajicek (work)
2021-03-15Doc: Document channel debug optionsOndrej Zajicek (work)
2021-03-12Rate-limit scheduling of work-eventsOndrej Zajicek (work)
In general, events are code handling some some condition, which is scheduled when such condition happened and executed independently from I/O loop. Work-events are a subgroup of events that are scheduled repeatedly until some (often significant) work is done (e.g. feeding routes to protocol). All scheduled events are executed during each I/O loop iteration. Separate work-events from regular events to a separate queue and rate limit their execution to a fixed number per I/O loop iteration. That should prevent excess latency when many work-events are scheduled at one time (e.g. simultaneous reload of many BGP sessions).
2021-03-10Static: Implement reload hookOndrej Zajicek (work)
2021-03-09Nest: No automatic ROA reload on non-reloadable channelsOndrej Zajicek (work)
2021-02-12Nest: Add option to control automatic RPKI reloadOndrej Zajicek (work)
Also, no automatic reload for BGP channels without import/export table.
2021-02-10Tests: Add missing mockup function to testsOndrej Zajicek (work)
2021-02-10BGP: Add support for BGP hostname capabilityVincent Bernat
This is an implementation of draft-walton-bgp-hostname-capability-02. It is implemented since quite some time for FRR and in datacenter, this gives a nice output to avoid using IP addresses. It is disabled by default. The hostname is retrieved from uname(2) and can be overriden with "hostname" option. The domain name is never set nor displayed. Minor changes by committer.
2021-02-10Nest: Automatic channel reloads based on RPKI changesOndrej Zajicek (work)
If there are roa_check() calls in channel filters, then the channel subscribes to ROA table notifications, which are sent when ROA tables are updated (subject to settle time) and trigger channel reload or refeed.
2021-02-07Filter: Recursive filter iteration codeOndrej Zajicek (work)
Add macros for recursive filter iteration that allows to examine all instructions reachable from a filter.
2021-01-22MRT: Fix MP-BGP next hopsOndrej Zajicek (work)
Flag signalling that MP-BGP mode should be used got reset after first batch of routes, so remaining routes were processed without that, leading to missing MP_REACH_NLRI attribute. Thanks to Piotr Wydrych for the bugreport.
2021-01-14Netlink: Ignore dead routesOndrej Zajicek (work)
With net.ipv4.conf.XXX.ignore_routes_with_linkdown sysctl, a user can ensure the kernel does not use a route whose target interface is down. Such route is marked with a 'dead' / RTNH_F_DEAD flag. Ignore these routes or multipath nexthops during scan. Thanks to Vincent Bernat for the original patch.
2021-01-12Build: Fix tags generationOndrej Zajicek (work)
2021-01-12MRT: Fix IPv6 table dumpsOndrej Zajicek (work)
Add fake MP_REACH_NLRI attribute with BGP next hop when encoding MRT table dumps for IPv6 routes. That is necessary to encode next hop as NEXT_HOP attribute is not used for MP-BGP. Thanks to Santiago Aggio for the bugreport.
2021-01-10BFD: Dispatch sessions also by interface indexOndrej Zajicek (work)
Direct BFD sessions needs to be dispatched not only by IP addresses, but also by interfaces, in order to avoid collisions between neighbors with the same IPv6 link-local addresses. Extend BFD session hash_ip key by interface index to handle that. Use 0 for multihop sessions. Thanks to Sebastian Hahn for the original patch.
2021-01-07RPKI: Remove port (and SSH username) from 'Cache server' output lineOndrej Zajicek (work)
It was mixed-up if hostname is IPv6 address, and reporting separate values (like port) on separate lines fits better into key-value style of 'show protocols all' output. Also, the patch simplifies transport identification formatting (although it is unused now). Thanks to Alarig Le Lay for the suggestion.
2021-01-07Kernel: Do not check templatesOndrej Zajicek (work)
So one can define kernel protocol template without channels. For other protocols, it is either irrelevant or already done. Thanks to Clemens Schrimpe for the bugreport.
2021-01-07Doc: Describe per-nexthop static route optionsOndrej Zajicek (work)
Also remove description of (no longer supported) per-route 'bfd' option, and add examples of IPv6 routes with link-local nexthops.
2021-01-06Nest: remove last_tx_filter_changeOndrej Zajicek (work)
No longer needed after redesign of export handling.
2021-01-06BGP: Deprecate 'missing lladdr' optionOndrej Zajicek (work)
The option is not implemented since transition to 2.0 and no plan to add it. Also remove some deprecated RTS_* valus from documentation. Thanks to Sébastien Parisot for notification.
2021-01-06Kernel: Fix handling of krt_realm with ECMP routesOndrej Zajicek (work)
For ECMP routes, RTA_FLOW attribute must be set per-nexthop, not per-route. Our corresponding krt_realm attribute is per-route. Thanks to Mikhail Petrov for the bugreport.
2020-12-29Nest: Read Babel metric as IGP metricJames Lu
(Minor syntactic changes by committer)
2020-12-28Static: Fix handling of 'net' attribute in per-route filtersOndrej Zajicek (work)
We need to define 'net' field temporarily as it may be accessed by per-route filters. Thanks to Damian Zaremba for the bugreport.
2020-12-28Filter: Fix return on top-levelOndrej Zajicek (work)
Broken detection of top-level case caused crash when return was called from top-of-stack position. It should behave as reject/accept. Thanks to Damian Zaremba for the bugreport.
2020-12-07Nest: Per-channel debug flagsOndrej Zajicek (work)
The patch add support for per-channel debug flags, currently just 'states', 'routes', and 'filters'. Flag 'states' is used for channel state changes, remaining two for routes passed through the channel. The per-protocol debug flags 'routes'/'filters' still enable reporting of routes for all channels, to keep existing behavior. The patch causes minor changes in some log messages.
2020-12-02Filter: Add 'weight' route attributeOndrej Zajicek (work)
Add 'weight' route attribute that allows to get and set ECMP weight of nexthops. Similar to 'gw' attribute, it is limited to the first nexthop, but it is useful for handling BGP multipath, where an ECMP route is merged from multiple regular routes.
2020-11-25BGP: Zero the newly allocated bucket structureOndrej Zajicek (work)
This fixes an issue with dirty node passed to add_tail(). Thanks to Andreas Rammhold for the initial patch.
