[PATCH] batman-adv: Avoid sizeof on flexible structure

by Sven Eckelmann

The batadv_dhcp_packet is used to read in parts of the DHCP packet and extract relevant information for the distributed arp table. But the structure contained the flexible member "options" which is no where used in the code. A sizeof on this kind of type would return the size of everything except the flexible member. But sparse will detect this kind of sizeof and warn with warning: using sizeof on a flexible structure This can be avoided by dropping the unused flexible member.

Routing Announcement Alfred Through

by nybash110998＠gmail.com

Hello Everyone! I want to present to the community my idea about spreading static ipv4 routes between mesh nodes. So, it is my first project in C, before I only have an experience in bash. I know, it might have some weird methods (first painting cannot be good), but I am trying my best. You can see what I suggest on my github page: https://github.com/nickbash11/raat , there you will find comprehensive information about what and how. It just tries to recap the "community" mode in BMX6/BMX7 but with ALFRED. For now I test it between some virtualbox machines with OpenWRT 18/19. This time I do not have hardware resources (routers) to test it on the real network :( All my devices are busy with qMp and I want to try some "pure" in the future, but I really used to see that each node has its own network behind it. Maybe, I have invented a bicycle... don't no, anyway, check me out.

[PATCH 1/2] vxlan: Add needed_headroom for lower device

by Sven Eckelmann

It was observed that sending data via batadv over vxlan (on top of wireguard) reduced the performance massively compared to raw ethernet or batadv on raw ethernet. A check of perf data showed that the vxlan_build_skb was calling all the time pskb_expand_head to allocate enough headroom for: min_headroom = LL_RESERVED_SPACE(dst->dev) + dst->header_len + VXLAN_HLEN + iphdr_len; But the vxlan_config_apply only requested needed headroom for: lowerdev->hard_header_len + VXLAN6_HEADROOM or VXLAN_HEADROOM So it completely ignored the needed_headroom of the lower device. The first caller of net_dev_xmit could therefore never make sure that enough headroom was allocated for the rest of the transmit path.
