From c83876265eeae3591bfe90375503728e633cb807 Mon Sep 17 00:00:00 2001 From: Ondrej Zajicek Date: Thu, 11 Feb 2010 22:27:06 +0100 Subject: Fixes a tricky bug in the pipe protocol. When uncofiguring the pipe and the peer table, the peer table was unlocked when pipe protocol state changed to down/flushing and not to down/hungry. This leads to the removal of the peer table before the routes from the pipe were flushed. The fix leads to adding some pipe-specific hacks to the nest, but this seems inevitable. --- proto/pipe/pipe.c | 21 ++++++++++----------- 1 file changed, 10 insertions(+), 11 deletions(-) (limited to 'proto/pipe/pipe.c') diff --git a/proto/pipe/pipe.c b/proto/pipe/pipe.c index aa76a152..d9df03ba 100644 --- a/proto/pipe/pipe.c +++ b/proto/pipe/pipe.c @@ -138,6 +138,9 @@ pipe_start(struct proto *P) * end of the pipe (we need to do this in order to get different * filters and announce functions and it unfortunately involves * a couple of magic trickery). + * + * The phantom protocol is used ONLY in announce hooks and + * therefore in do_rte_announce() function. */ ph = mb_alloc(P->pool, sizeof(struct pipe_proto)); memcpy(ph, p, sizeof(struct pipe_proto)); @@ -170,20 +173,10 @@ pipe_start(struct proto *P) */ a = proto_add_announce_hook(P, p->peer); a->proto = &ph->p; - rt_lock_table(p->peer); return PS_UP; } -static int -pipe_shutdown(struct proto *P) -{ - struct pipe_proto *p = (struct pipe_proto *) P; - - rt_unlock_table(p->peer); - return PS_DOWN; -} - static struct proto * pipe_init(struct proto_config *C) { @@ -234,13 +227,19 @@ pipe_reconfigure(struct proto *P, struct proto_config *new) return 1; } +struct rtable * +pipe_get_peer_table(struct proto *P) +{ + struct pipe_proto *p = (struct pipe_proto *) P; + return p->peer; +} + struct protocol proto_pipe = { name: "Pipe", template: "pipe%d", postconfig: pipe_postconfig, init: pipe_init, start: pipe_start, - shutdown: pipe_shutdown, reconfigure: pipe_reconfigure, get_status: pipe_get_status, }; -- cgit v1.2.3
