[batman-adv] master: batman-adv: fix packet checksum in receive path (798174b)
by postmaster＠open-mesh.org 23 Jan '18

23 Jan '18

Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 798174b15153afd88268f2f87811602f68b3f2c6 Author: Matthias Schiffer <mschiffer(a)universe-factory.net> Date: Tue Jan 23 10:59:49 2018 +0100 batman-adv: fix packet checksum in receive path eth_type_trans() internally calls skb_pull(), which does not adjust the skb checksum; skb_postpull_rcsum() is necessary to avoid log spam of the form "bat0: hw csum failure" when packets with CHECKSUM_COMPLETE are received. Note that in usual setups, packets don't reach batman-adv with CHECKSUM_COMPLETE (I assume NICs bail out of checksumming when they see batadv's ethtype?), which is why the log messages do not occur on every system using batman-adv. I could reproduce this issue by stacking batman-adv on top of a VXLAN interface.
