From b02e40111ea8d97bf1c3bfa25970ee0d828cd7bc Mon Sep 17 00:00:00 2001 From: Ondrej Filip Date: Mon, 4 Sep 2000 19:42:17 +0000 Subject: I allocate struct ifa before unlocking. So route exported to OSPF are correct. I work also with interfaces that have some problems with socket opening. I declare them as stub. --- proto/ospf/iface.c | 162 +++++++++++++++++++++++++---------------------------- 1 file changed, 76 insertions(+), 86 deletions(-) (limited to 'proto/ospf/iface.c') diff --git a/proto/ospf/iface.c b/proto/ospf/iface.c index e82d8f3..0c39862 100644 --- a/proto/ospf/iface.c +++ b/proto/ospf/iface.c @@ -314,6 +314,10 @@ ospf_if_notify(struct proto *p, unsigned flags, struct iface *iface) struct ospf_iface_patt *ip=NULL; struct ospf_iface *ifa; struct object_lock *lock; + struct nbma_node *nbma,*nb; + u8 i; + sock *mcsk; + DBG("%s: If notify called\n", p->name); if (iface->flags & IF_IGNORE) @@ -330,12 +334,74 @@ ospf_if_notify(struct proto *p, unsigned flags, struct iface *iface) if(ip) { OSPF_TRACE(D_EVENTS, "Using interface %s.", iface->name); + + ifa=mb_allocz(p->pool, sizeof(struct ospf_iface)); + ifa->proto=po; + ifa->iface=iface; + + ifa->an=ac->areaid; + ifa->cost=ip->cost; + ifa->rxmtint=ip->rxmtint; + ifa->inftransdelay=ip->inftransdelay; + ifa->priority=ip->priority; + ifa->helloint=ip->helloint; + ifa->pollint=ip->pollint; + ifa->strictnbma=ip->strictnbma; + ifa->waitint=ip->waitint; + ifa->deadc=ip->deadc; + ifa->stub=ip->stub; + ifa->autype=ip->autype; + memcpy(ifa->aukey,ip->password,8); + ifa->options=2; /* FIXME what options? */ + + if(ip->type==OSPF_IT_UNDEF) + ifa->type=ospf_iface_clasify(ifa->iface, (struct proto *)ifa->proto); + else ifa->type=ip->type; + + init_list(&ifa->neigh_list); + init_list(&ifa->nbma_list); + WALK_LIST(nb,ip->nbma_list) + { + nbma=mb_alloc(p->pool,sizeof(struct nbma_node)); + nbma->ip=nb->ip; + nbma->eligible=nb->eligible; + add_tail(&ifa->nbma_list, NODE nbma); + } + + /* Add hello timer */ + ifa->hello_timer=tm_new(p->pool); + ifa->hello_timer->data=ifa; + ifa->hello_timer->randomize=0; + ifa->hello_timer->hook=hello_timer_hook; + ifa->hello_timer->recurrent=ifa->helloint; + DBG("%s: Installing hello timer.
