+Subject: [PATCH 1/2] 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 nor occur on every
+system using batman-adv. I could reproduce this issue by stacking
+batman-adv on top of a VXLAN interface.

+Subject: [PATCH 2/2] 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 nor occur on every
+system using batman-adv. I could reproduce this issue by stacking
+batman-adv on top of a VXLAN interface.

+Subject: batman-adv: always assume 2-byte packet alignment
+X-Git-Url: https://git.open-mesh.org/batman-adv.git/commitdiff_plain/0509fc0c128ba2891770305c57c9b6a3a61ea7bd
+
+batman-adv: always assume 2-byte packet alignment
+
+NIC drivers generally try to ensure that the "network header" is aligned
+to a 4-byte boundary. This is not always possible: When Ethernet frames are
+encapsulated in other packets with 4-byte aligned headers, the inner
+Ethernet header will have 4-byte alignment, and in consequence, the inner
+network header is aligned to 2, but not to 4 bytes.
+
+Most parts of batman-adv only care about 2-byte alignment; in particular,
+no unaligned accesses occur in performance-critical paths that handle
+actual payload data. This is not true for OGM handling: the seqno and crc
+fields are accessed as 32-bit values. To avoid these unaligned accesses,
+this patch reduces the expected packet alignment to 2 bytes for all of
+batadv's packet types.
+
+As no unaligned accesses existed on the performance-critical paths anyways,
+this chance does have any (positive or negative) effect on performance, but
+it still makes sense to avoid these accesses to prevent log noise when
+examining other unaligned accesses in the kernel while batman-adv is
+active.
