X-Git-Tag: release-1.0.11~8 X-Git-Url: https://git.librecmc.org/?p=oweals%2Ftinc.git;a=commitdiff_plain;h=d922db253cd098bc038449e5c591cc94c1019952 Make maxmtu equal to minmtu when fixing the path MTU to a node. This ensures MTU probes used to ping nodes are not too large, and prevents restarting MTU probing unnecessarily. --- diff --git a/src/net_packet.c b/src/net_packet.c index 626f8b1..3466f87 100644 --- a/src/net_packet.c +++ b/src/net_packet.c @@ -91,6 +91,10 @@ void send_mtu_probe(node_t *n) { } if(n->mtuprobes == 30 || (n->mtuprobes < 30 && n->minmtu >= n->maxmtu)) { + if(n->minmtu > n->maxmtu) + n->minmtu = n->maxmtu; + else + n->maxmtu = n->minmtu; n->mtu = n->minmtu; ifdebug(TRAFFIC) logger(LOG_INFO, "Fixing MTU of %s (%s) to %d after %d probes", n->name, n->hostname, n->mtu, n->mtuprobes); n->mtuprobes = 31;
