Subject: [PATCH 4.19 004/120] net: Fix gro aggregation for udp encaps with zero csum
Date: Mon, 15 Mar 2021 14:55:55 +0100	[thread overview]
Message-ID: <20210315135720.152935021@linuxfoundation.org> (raw)
In-Reply-To: <20210315135720.002213995@linuxfoundation.org>

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Daniel Borkmann <daniel@iogearbox.net>

commit 89e5c58fc1e2857ccdaae506fb8bc5fed57ee063 upstream.

We noticed a GRO issue for UDP-based encaps such as vxlan/geneve when the
csum for the UDP header itself is 0. In that case, GRO aggregation does
not take place on the phys dev, but instead is deferred to the vxlan/geneve
driver (see trace below).

The reason is essentially that GRO aggregation bails out in udp_gro_receive()
for such case when drivers marked the skb with CHECKSUM_UNNECESSARY (ice, i40e,
others) where for non-zero csums 2abb7cdc0dc8 ("udp: Add support for doing
checksum unnecessary conversion") promotes those skbs to CHECKSUM_COMPLETE
and napi context has csum_valid set. This is however not the case for zero
UDP csum (here: csum_cnt is still 0 and csum_valid continues to be false).

At the same time 57c67ff4bd92 ("udp: additional GRO support") added matches
on !uh->check ^ !uh2->check as part to determine candidates for aggregation,
so it certainly is expected to handle zero csums in udp_gro_receive(). The
purpose of the check added via 662880f44203 ("net: Allow GRO to use and set
levels of checksum unnecessary") seems to catch bad csum and stop aggregation
right away.

One way to fix aggregation in the zero case is to only perform the !csum_valid
check in udp_gro_receive() if uh->check is infact non-zero.
