* ospf6d: support unicast hellos on PtP/PtMPDavid Lamparter2023-10-101-0/+5
| | | | | | | | Some lower layers still don't handle multicast correctly (or efficiently.) Add option to send unicast hellos on explicitly configured neighbors for PtP/PtMP. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* *: Rename `struct thread` to `struct event`Donald Sharp2023-03-241-10/+10
| | | | | | | | | Effectively a massive search and replace of `struct thread` to `struct event`. Using the term `thread` gives people the thought that this event system is a pthread when it is not Signed-off-by: Donald Sharp <sharpd@nvidia.com>

* *: Change thread->func to return void instead of intDonald Sharp2022-02-241-10/+10
| | | | | | | The int return value is never used. Modify the code base to just return a void instead. Signed-off-by: Donald Sharp <sharpd@nvidia.com>

| | | | | | | enqueue outgoing dbdesc messages to the end of the tx FIFO and schedule the ospf6_write task to deal with them. Signed-off-by: Pat Ruddy <pat@voltanet.io>

| | | | | | | Add per interface fifo and per instance write list as a precursor to implementing fairer sharing of the ospf6 oscket resources. Signed-off-by: Pat Ruddy <pat@voltanet.io>
* ospf6d: fix invalid "no debug ospf6 message unknown"Igor Ryzhov2021-05-261-2/+2
| | | | | | | The message is always shown in the config, because IS_OSPF6_DEBUG_MESSAGE works incorrectly when negated because of missing outer brackets. Signed-off-by: Igor Ryzhov <iryzhov@nfware.com>
* ospf6d: Make debug logs configurable to only display message headerslynne2021-04-291-6/+26
| | | | | | | | | | This change allows the user to only log the message header and not include all the LSAs in each packet. In a large setup printing out all the LSAs in each packet can make the system very hard to debug. When the user finds an issue with the adjacency not coming up or in a specific packet type they can turn on a full dump of the message. Signed-off-by: Lynne Morrison <lynne@voltanet.io>

* *: 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This vulnerability (CERT-FI #514840) was reported by CROSS project. ospf6d processes IPv6 prefix structures in incoming packets without verifying that the declared prefix length is valid.

* ospf6d: Have ospf6d cleanup when it terminates normallyTom Goff2011-03-211-0/+1
| | | | | | | | | | | | | | | A clean exit makes it easier to use memory debuggers. * ospf6_asbr.c: (ospf6_asbr_terminate) Add a function to do route map cleanup. * ospf6_lsa.c: (ospf6_lsa_terminate) Add a function to cleanup the lsa handler vector. * ospf6_main.c: (ospf6_exit) Add an function that causes ospf6d to gracefully exit. * ospf6_message.c: (ospf6_message_terminate) Add a function that frees the send and receive buffers. * ospf6_top.c: (ospf6_delete) Enable the ospf6_delete() function. Disable ospf6 before freeing everything.
* [trivia] finish off static'ification of ospf6d and ripngdPaul Jakma2008-08-221-20/+20
| | | | | | | | | 2008-08-15 Paul Jakma <paul.jakma@sun.com> * {ospf6d,ripngd}/*: Finish job of marking functions as static, or exporting declarations for them, to quell warning noise with Quagga's GCC default high-level of warning flags. Thus allowing remaining, more useful warnings to be more easily seen.
