[PATCH v4 0/5] Implementation of a Stateless Multicast Packet Type
by Linus Lüssing 27 Jan '23

27 Jan '23

Hi, The following patchset implements a stateless, TVLV capable batman-adv multicast packet type. The new batman-adv multicast packet type allows to contain several originator destination MAC addresses within a TVLV. Routers on the way will potentially split the batman-adv multicast packet and adjust its tracker TVLV contents. Routing decisions are still based on the selected BATMAN IV or BATMAN V routing algorithm. So this new batman-adv multicast packet type retains the same loop-free properties. The purpose of this new packet type is to allow to forward an IP multicast packet with less transmissions / overhead than the multicast-via-multiple-unicasts approach. Or to reach a lot more destinations (currently up to 196, depending on the payload size, see Wiki documentation for details) than with the default multicast fanout for the via-unicasts approach. This will allow using applications like mDNS again in several Freifunk communities. And with less transmissions will also make more bulky multicast applications, like media streaming (to an assessable amount of receivers) a lot more feasible. This approach is way simpler than the original multicast (tracker) packet approach we envisioned years ago. As it involves no maintenance of an extra, state based multicast routing table. However the TVLV capability should allow to extend things later, to split control and data plane a bit more for instance, to further increase the number of destinations, to further reduce overhead. A compact overview can be found in the Wiki here, including limitations: https://www.open-mesh.org/projects/batman-adv/wiki/Multicast-Packet-Type Regards, Linus ___ Changelog v4: * PATCH 4/5: * add missing include for linux/types.h in multicast.h * add missing kerneldoc for @bat_priv in batadv_mcast_forw_push_dest() and batadv_mcast_forw_push_tvlvs() * use sizeof_field(type, field) instead of sizeof(((type *)0)->field) in batadv_mcast_forw_push_dest() * PATCH 5/5: * rename num_dests_remove to num_dests_reduce in batadv_mcast_forw_shrink_align_offse() to fix kerneldocs and for consistency * fix typo in kerneldoc in batadv_mcast_forw_shrink_update_headers() -> @num_dest_reduce -> @num_dests_reduce * use sizeof_field(type, field) instead of sizeof(((type *)0)->field) in batadv_mcast_forw_shrink_align_offset() Changelog v3: * PATCH 1/5: * remove now obsolete includes * PATCH 2/5: * fix batadv_tvlv_handler_register() in network-coding.c * add missing include for linux/skbuff.h * move variable declarations out of the switch case in batadv_tvlv_call_handler() * PATCH 3/5: * remove unnecessary include of multicast.h in routing.c * add a few missing includes to multicast_forw.c (linux/byteorder/generic.h, linux/errno.h, linux/gfp.h, linux/stddef.h uapi/linux/batadv_packet.h, multicast.h) * PATCH 4/5: * add missing rcu_read_unlock() in error case before returning in batadv_mcast_forw_push_dests_list() * remove unnecessary include of soft-interface.h in multicast_forw.c * add a few missing includes to multicast_forw.c (linux/bug.h, linux/build_bug.h, linux/limits.h, linux/rculist.h, linux/rcupdate.h, linux/string.h) * make batadv_mcast_forw_mode_by_count() static * fix return types in the declaration of batadv_mcast_forw_packet_hdrlen() and batadv_mcast_forw_push() in multicast.h * fix typo in commit message: "that the are capable of" -> "that the*y* are capable of" * PATCH 5/5: * make batadv_mcast_forw_shrink_pack_dests() adhere to 80 characters per line for consistency * add a "continue" statement after the jump label in batadv_mcast_forw_shrink_pack_dests() to silence the sparse error "error: label at end of compound statement" Changelog v2: * Add "[PATCH v2 0/5]" prefix to title of cover letter, so that Patchwork can hopefully find it - no other changes

using alfred (or other means) to collect link data
by dan 29 Dec '22

29 Dec '22

I'm looking for a way to collect link data between nodes. My google-fu has failed me on how to get node-to-node data like latency or throughput etc. Is there any model built in to batman-adv/alfred to poll this data? I only really finding the batvis data which is just returning metric. I'm mostly wanting to see how traffic is flowing, where links are being more heavily used especially if those are not shortest paths (suggests I have something to fix) and to keep track of a sort of high water mark to metric ratio. ie, this link has done 260Mbps with the link metric <=1.2 in the last 48 hours and it's currently doing 105Mbps at 1.08 metric. my current plan is to run scripts to find 1 hop neighbors and either so an arp-scan or find IP and ping directly on a schedule and store that in alfred or just push it up to my database but this is a little brute-forcy considering batman-adv is doing some of this work to create the route metric in the first place. Any advice appreciated. Thanks.

[PATCH] build_test: don't warn about "Macro argument reuse" in multicast_forw.c
by Linus Lüssing 27 Dec '22

27 Dec '22

It's tricky to avoid reusing an argument in a for-each like macro. This is to silence the following warning: CHECK: Macro argument reuse 'num_dests' - possible side-effects? #789: FILE: net/batman-adv/multicast_forw.c:35: +#define batadv_mcast_forw_tracker_for_each_dest(dest, num_dests) \ + for (; num_dests; num_dests--, (dest) += ETH_ALEN) CHECK: Macro argument reuse 'num_dests' - possible side-effects? #792: FILE: net/batman-adv/multicast_forw.c:38: +#define batadv_mcast_forw_tracker_for_each_dest_rev(dest, num_dests) \ + for (; num_dests; num_dests--, (dest) -= ETH_ALEN) Later, once < 5.18 is out of our compat range we can rely on C99 syntax and use variable declarations inside a for loop, readd the check and rewrite the macro to something like this: #define batadv_mcast_forw_tracker_for_each_dest(dest, num_dests) \ for (typeof(num_dests) __batadv_forw_num_dests = num_dests; \ *__batadv_forw_num_dests; \ (*__batadv_forw_num_dests)--, (dest) += ETH_ALEN) Signed-off-by: Linus Lüssing <linus.luessing(a)c0d3.blue> --- checkstuff.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/checkstuff.sh b/checkstuff.sh index 207652ce4fbe..be49709dcb3b 100755 --- a/checkstuff.sh +++ b/checkstuff.sh @@ -191,7 +191,7 @@ test_checkpatch() continue fi - if [ "${fname}" = "log.h" ]; then + if [ "${fname}" = "log.h" -o "${fname}" = "multicast_forw.c" ]; then cp_extra_params="${cp_extra_params} --ignore MACRO_ARG_REUSE" fi -- 2.39.0

[RFC PATCH] batman-adv: Drop support for Linux < 4.14
by Sven Eckelmann 16 Dec '22

The Linux Kernel 4.9 reached its end of life [1] after 6 years. Instead it is recommended to use at least kernel 4.14. It is also over 5 years old but still maintained by the stable kernel team.
