BIRD performance in a dynamic scenario
by Maxime Peim (mpeim) 01 Jun '25

01 Jun '25

Hi everyone, First of all, thanks a lot for BIRD ! I have some questions about the dynamicity of BIRD wiht BGP. In a scenario where routes needs to be updated accondingly depending on some external informations, I find out that those informations would need to be written into the BIRD configuration file. As an example, if we need to add a bgp community based on the peer address (already known), we would need something like that : ```bird function get_community_from_peer_address(ip addr) -> pair { case addr { <addr1> : (1,1) ; <addr2> : (245, 12434) ; … else : (0, 0) ; } } ``` And we could update that function if needed in the future but the configuration will need to be parsed each time. If the rate of update is high, it can become a bootleneck. So I would like to know if I am going the right direction doing that way ? Is there a plan for a direct API to BIRD internals instead of passing a configuration file ? Thanks in advance for your answer, Maxime Peim

[PATCH v3.1] BFD: remove unused spinlock
by Zhang Maiyun 01 Jun '25

01 Jun '25

The only use of the spinlock in `struct bfd_proto` was removed in 38acb415f and now it should be fine to remove it. The check for `pthread_spin*` in `aclocal.m4` is also removed accordingly. This makes it possible to port BFD support to platforms without spinlocks (e.g. Darwin) Signed-off-by: Zhang Maiyun <me(a)maiyun.me> --- aclocal.m4 | 4 ++-- proto/bfd/bfd.h | 2 -- 2 files changed, 2 insertions(+), 4 deletions(-) diff --git a/aclocal.m4 b/aclocal.m4 index dd5cca35..7fc9c995 100644 --- a/aclocal.m4 +++ b/aclocal.m4 @@ -91,8 +91,8 @@ AC_DEFUN([BIRD_CHECK_PTHREADS], [ pthread_t pt; pthread_create(&pt, NULL, NULL, NULL); - pthread_spinlock_t lock; - pthread_spin_lock(&lock); + pthread_mutex_t lock; + pthread_mutex_lock(&lock); ] ) ], diff --git a/proto/bfd/bfd.h b/proto/bfd/bfd.h index 71f1090d..d8b5f8ea 100644 --- a/proto/bfd/bfd.h +++ b/proto/bfd/bfd.h @@ -82,8 +82,6 @@ struct bfd_proto { struct proto p; - pthread_spinlock_t lock; - pool *tpool; struct birdloop *eloop; -- 2.39.5 (Apple Git-154)
