2023-08-28BGP: Tunnel Encapsulation attributeMikael Magnusson
Refer to RFC 9012, The BGP Tunnel Encapsulation Attribute.
2023-08-22Merge branch 'bmp'Ondrej Zajicek
2023-08-22BGP: Update RFC referenceOndrej Zajicek
RFC 5549 was obsoleted by RFC 8950.
2023-08-01BMP: Simplify route monitoring hooksOndrej Zajicek
No need for *_begin(), *_commit(), and *_end() hooks. The hook *_notify() is sufficient for everything.
2023-06-08BMP: Support multiple instances of BMP protocolOndrej Zajicek
Add internal BMP functions with plicit bmp_proto *p as first argument, which allows using TRACE() macro. Keep list of BMP instances and call internal functions. Old BMP functions are wrappers that call internal functions for all enabled BMP instances. Extract End-of-RIB mark into separate function. Based on patch from Michal Zagorski <mzagorsk@akamai.com>. Thanks!
2023-05-01BGP: Save sent and received OPEN messagesOndrej Zajicek
These are necessary for BMP Peer UP message and it is better to keep them in BGP than in BMP (so BMP could be restarted or added later).
2023-04-16BMP: Remove duplicate functions for update encodingOndrej Zajicek (work)
Use existing BGP functions also for BMP update encoding.
2023-04-16BMP: Minor cleanupsOndrej Zajicek (work)
Remove redundant 'disable' option, simplify IP address serialization, and remove useless macros.
2023-04-16BMP protocol supportPawel Maslanka
Initial implementation of a basic subset of the BMP (BGP Monitoring Protocol, RFC 7854) from Akamai team. Submitted for further review and improvement.
2023-04-14BGP: Add 'allow bgp_med' option for EBGP sessionsTrisha Biswas
This option allows to treat bgp_med as regular transitive attribute on EBGP sessions (without hacks in filters). Minor changes from committer.
2023-04-04BGP: Fix bgp_med handlingOndrej Zajicek
Missing translation from BGP attribute ID to eattr ID in bgp_unset_attr() broke automatic removal of bgp_med during export to EBGP peers. Thanks to Edward Sun for the bugreport.
2023-02-19BGP: Update RFC referencesOndrej Zajicek
2023-01-20BGP: Add received role value to role mismatch log messageOndrej Zajicek
2022-12-09BGP: Improve handling of hold and keepalive timersOndrej Zajicek
The effective keepalive time now scales relative to the negotiated hold time, to maintain proportion between the keepalive time and the hold time. This avoids issues when both keepalive and hold times were configured, the hold time was negotiated to a smaller value, but the keepalive time stayed the same. Add new options 'min hold time' and 'min keepalive time', which reject session attempts with too small hold time. Improve validation of config options an their documentation. Thanks to Alexander Zubkov and Sergei Goriunov for suggestions.
2022-10-10BGP: Add option 'next hop prefer global'Ondrej Zajicek
Add BGP channel option 'next hop prefer global' that modifies BGP recursive next hop resolution to use global next hop IPv6 address instead of link-local next hop IPv6 address for immediate next hop of received routes.
2022-10-03BGP: Do not assume that all channels are struct bgp_channelOndrej Zajicek
In principle, the channel list is a list of parent struct proto and can contain general structures of type struct channel, That is useful e.g. for adding MPLS channels to BGP.
2022-07-24Merge branch 'master' into backportOndrej Zajicek
2022-07-11BGP: Implement BGP rolesEugene Bogomazov
Implement BGP roles as described in RFC 9234. It is a mechanism for route leak prevention and automatic route filtering based on common BGP topology relationships. It defines role capability (controlled by 'local role' option) and OTC route attribute, which is used for automatic route filtering and leak detection. Minor changes done by commiter.

2022-06-27Preexport callback now takes the channel instead of protocol as argumentMaria Matejka
Passing protocol to preexport was in fact a historical relic from the old times when channels weren't a thing. Refactoring that to match current extensibility needs.

2022-02-06BGP: Implement flowspec validation procedureOndrej Zajicek (work)
Implement flowspec validation procedure as described in RFC 8955 sec. 6 and RFC 9117. The Validation procedure enforces that only routers in the forwarding path for a network can originate flowspec rules for that network. The patch adds new mechanism for tracking inter-table dependencies, which is necessary as the flowspec validation depends on IP routes, and flowspec rules must be revalidated when best IP routes change. The validation procedure is disabled by default and requires that relevant IP table uses trie, as it uses interval queries for subnets.
2022-01-28BGP: Use proper class in attribute error messagesOndrej Zajicek (work)
Most error messages in attribute processing are in rx/decode step and these use L_REMOTE log class. But there are few that are in tx/export step and these should use L_ERR log class. Use tx-specific macro (REJECT()) in tx/export code and rename field err_withdraw to err_reject in struct bgp_export_state to ensure that appropriate error reporting macros are called in proper contexts.
2022-01-24BGP: Log route updates that were changed to withdrawsOndrej Zajicek (work)
Typical BGP error handling is treat-as-withdraw, where an invalid route is replaced with a withdraw. Log route network when it happens.
2022-01-09BGP: Add option 'free bind'Ondrej Zajicek (work)
The BGP 'free bind' option applies the IP_FREEBIND/IPV6_FREEBIND socket option for the BGP listening socket. Thanks to Alexander Zubkov for the idea.

2021-10-13BGP: Moved the suppressed and stale flags to pflagsMaria Matejka
2021-10-13IGP metric getter refactoring to protocol callbackMaria Matejka
Direct protocol hooks for IGP metric inside nest/rt-table.c make the protocol API unnecessarily complex. Instead, we use a proper callback.
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.
2021-01-12MRT: 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.
2021-01-06BGP: 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.
2020-11-12BFD: Better handling of BFD options in BGP configsOndrej Zajicek (work)
Merge multiple BFD option blocks in BGP configs instead of using the last one. That is necessary for proper handling of templates when BFD options are used both in a BGP template and in a BGP protocol derived from that template.
2020-11-08BFD: Allow per-request session optionsOndrej Zajicek (work)
BFD session options are configured per interface in BFD protocol. This patch allows to specify them also per-request in protocols requesting sessions (currently limited to BGP).

This is merely a const propagation. There was no problem in there.
2019-12-03BGP: Add some statisticsOndrej Zajicek (work)
Add some statistic counters to BGP consistent with BGP MIB (RFC 4273), including persistent 'FSM established transitions'.
2019-11-10BGP: Add option to enforce first AS in AS_PATHOndrej Zajicek (work)
This is optional check described in RFC 4271. Although this can be also done by filters, it is widely implemented option in BGP implementations. Thanks to Eugene Bogomazov for the original patch.
2019-11-04BGP: Add option to reject AS_SETsOndrej Zajicek (work)
There is a pending draft to make them obsolete
2019-10-09BGP: AIGP metric support (RFC 7311)Ondrej Zajicek (work)
2019-08-14BGP: implement Adj-RIB-OutOndrej Zajicek (work)
The patch implements optional internal export table to a channel and hooks it to BGP so it can be used as Adj-RIB-Out. When enabled, all exported (post-filtered) routes are stored there. An export table can be examined using e.g. 'show route export table bgp1.ipv4'.
2019-08-06BGP: Improve reconfigurationOndrej Zajicek (work)
Several BGP channel options (including 'next hop self') could be reconfigured without session reset, with just route refeed/refresh. The patch improves reconfiguration code to do it that way.

2019-06-30Nest: Add command to request graceful restartOndrej Zajicek (work)
When 'graceful down' command is entered, protocols are shut down with regard to graceful restart. Namely Kernel protocol does not remove routes and BGP protocol does not send notification, just closes the connection.
