[batman-adv] master: batman-adv: invalidate checksum on fragment reassembly (2c1bce0)
by postmaster＠open-mesh.org 23 Jan '18

23 Jan '18

Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 2c1bce065baa688bc1eca4116f83ca3b790432a5 Author: Matthias Schiffer <mschiffer(a)universe-factory.net> Date: Tue Jan 23 10:59:50 2018 +0100 batman-adv: invalidate checksum on fragment reassembly A more sophisticated implementation could try to combine fragment checksums when all fragments have CHECKSUM_COMPLETE and are split at even offsets. For now, we just set ip_summed to CHECKSUM_NONE to avoid "hw csum failure" warnings in the kernel log when fragmented frames are received. In consequence, skb_pull_rcsum() can be replaced with skb_pull(). 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.
