Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 67a50c93bceb534937d6a188eded79272ff6d55d Author: Linus Lüssing <linus.luessing(a)c0d3.blue> Date: Tue Mar 20 03:13:27 2018 +0100 batman-adv: fix multicast-via-unicast transmission with AP isolation For multicast frames AP isolation is only supposed to be checked on the receiving nodes and never on the originating one. Furthermore, the isolation or wifi flag bits should only be intepreted as such for unicast and never multicast TT entries. By injecting flags to the multicast TT entry claimed by a single target node it was verified in tests that this multicast address becomes unreachable, leading to packet loss. Omitting the "src" parameter to the batadv_transtable_search() call successfully skipped the AP isolation check and made the target reachable again.

[batman-adv] master: batman-adv: fix packet loss for broadcasted DHCP packets to a server (49b2132)

Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 49b2132f0fe2753a3b46103db9719898c5cd44aa Author: Linus Lüssing <linus.luessing(a)c0d3.blue> Date: Thu Mar 22 00:21:32 2018 +0100 batman-adv: fix packet loss for broadcasted DHCP packets to a server DHCP connectivity issues can currently occur if the following conditions are met: 1) A DHCP packet from a client to a server 2) This packet has a multicast destination 3) This destination has a matching entry in the translation table (FF:FF:FF:FF:FF:FF for IPv4, 33:33:00:01:00:02/33:33:00:01:00:03 for IPv6) 4) The orig-node determined by TT for the multicast destination does not match the orig-node determined by best-gateway-selection In this case the DHCP packet will be dropped. The "gateway-out-of-range" check is supposed to only be applied to unicasted DHCP packets to a specific DHCP server. In that case dropping the the unicasted frame forces the client to retry via a broadcasted one, but now directed to the new best gateway. A DHCP packet with broadcast/multicast destination is already ensured to always be delivered to the best gateway. Dropping a multicasted DHCP packet here will only prevent completing DHCP as there is no other fallback. So far, it seems the unicast check was implicitly performed by expecting the batadv_transtable_search() to return NULL for multicast destinations. However, a multicast address could have always ended up in the translation table and in fact is now common. To fix this potential loss of a DHCP client-to-server packet to a multicast address this patch adds an explicit multicast destination check to reliably bail out of the gateway-out-of-range check for such destinations. The issue and fix were tested in the following three node setup: - Line topology, A-B-C - A: gateway client, DHCP client - B: gateway server, hop-penalty increased: 30->60, DHCP server - C: gateway server, code modifications to announce FF:FF:FF:FF:FF:FF Without this patch, A would never transmit its DHCP Discover packet due to an always "out-of-range" condition. With this patch, a full DHCP handshake between A and B was possible again.
