* * : include event ptr in event_execute apiMark Stapp2023-07-251-5/+6
| | | | | | | | | Include an event ptr-to-ptr in the event_execute() api call, like the various schedule api calls. This allows the execute() api to cancel an existing scheduled task if that task is being executed inline. Signed-off-by: Mark Stapp <mjs@labn.net>

* ospf6d: introduce support for Graceful Restart (restarting mode)Renato Westphal2021-09-161-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 5187 specifies the Graceful Restart enhancement to the OSPFv3 routing protocol. This commit implements support for the GR restarting mode. Here's a quick summary of how the GR restarting mode works: * GR can be enabled on a per-instance basis using the `graceful-restart [grace-period (1-1800)]` command; * To perform a graceful shutdown, the `graceful-restart prepare ipv6 ospf` EXEC-level command needs to be issued before restarting the ospf6d daemon (there's no specific requirement on how the daemon should be restarted); * `graceful-restart prepare ospf` will initiate the graceful restart for all GR-enabled instances by taking the following actions: o Flooding Grace-LSAs over all interfaces o Freezing the OSPF routes in the RIB o Saving the end of the grace period in non-volatile memory (a JSON file stored in `$frr_statedir`) * Once ospf6d is started again, it will follow the procedures described in RFC 3623 until it detects it's time to exit the graceful restart (either successfully or unsuccessfully). Testing done: * New topotest featuring a multi-area OSPF topology (including stub and NSSA areas); * Successful interop tests against IOS-XR routers acting as helpers.

Check Intra Area Prefix LSA update at R1 and R3 which would have ECMP paths with effective two paths and two nexthops (from R2 and R4). stop frr at R3 and R1 and R4 route changes back to one nexthop and one paht.

* ospf6d: Handle Premature Aging of LSAsChirag Shah2018-02-151-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 2328 (14.1) Premature aging of LSAs from routing domain : When ospf6d is going away (router going down), send MAXAGEd self originated LSAs to all neighbors in routing domain to trigger Premature aging to remove from resepective LSDBs. Neighbor Router Reboot: Upon receiving Self-originate MAXAGEd LSA, simply discard, Current copy could be non maxaged latest. For neighbor advertised LSA's (current copy in LSDB) is set to MAXAGE but received new LSA with Non-MAXAGE (with current age), discard the current MAXAGE LSA, Send latest copy of LSA to neighbors and update the LSDB with new LSA. When a neighbor transition to FULL, trigger AS-External LSAs update from external LSDB to new neighbor. Testing: R1 ---- DUT --- R5 | \ R2 R3 | R4 Area 1: R5 and DUT Area 0: DUT, R1, R2, R3 Area 2: R2 R4 Add IPv6 static routes at R5 Redistribute kernel routes at R5, Validate routes at R4, redistributed via backbone to area 2. Stop n start frr.service at R5 and validated MAXAGE LSAs then recent age LSAs in Database at DUT-R4. Validated external routes installed DUT to R4.

* *: make consistent & update GPLv2 file headersDavid Lamparter2017-05-151-4/+3
| | | | | | | | | | | The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.) Note: I've intentionally left intact other "variations" of the copyright header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

* *: remove THREAD_ON macros, add nullity checkQuentin Young2017-05-091-22/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way thread.c is written, a caller who wishes to be able to cancel a thread or avoid scheduling it twice must keep a reference to the thread. Typically this is done with a long lived pointer whose value is checked for null in order to know if the thread is currently scheduled. The check-and-schedule idiom is so common that several wrapper macros in thread.h existed solely to provide it. This patch removes those macros and adds a new parameter to all thread_add_* functions which is a pointer to the struct thread * to store the result of a scheduling call. If the value passed is non-null, the thread will only be scheduled if the value is null. This helps with consistency. A Coccinelle spatch has been used to transform code of the form: if (t == NULL) t = thread_add_* (...) to the form thread_add_* (..., &t) The THREAD_ON macros have also been transformed to the underlying thread.c calls.

* *: nuke ^L (page feed)David Lamparter2014-06-041-1/+1
| | | | | | | | | | | | | | Quagga sources have inherited a slew of Page Feed (^L, \xC) characters from ancient history. Among other things, these break patchwork's XML-RPC API because \xC is not a valid character in XML documents. Nuke them from high orbit. Patches can be adapted simply by: sed -e 's%^L%%' -i filename.patch (you can type page feeds in some environments with Ctrl-V Ctrl-L) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

| | | | | | | | | | | | | | OSPFv3: Support setting/clearing overload bit on router It is sometimes necessary for a router to gracefully remove itself from the SPF tree i.e. it cannot act as a transit router. It does this by setting the overload bit in the router LSA. This patch adds support for enabling/disabling the overload bit.
