5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] wireguard: socket: mark skbs as not on list when receiving
|
|
via gro
|
|
|
|
commit 736775d06bac60d7a353e405398b48b2bd8b1e54 upstream.
|
|
|
|
Certain drivers will pass gro skbs to udp, at which point the udp driver
|
|
simply iterates through them and passes them off to encap_rcv, which is
|
|
where we pick up. At the moment, we're not attempting to coalesce these
|
|
into bundles, but we also don't want to wind up having cascaded lists of
|
|
skbs treated separately. The right behavior here, then, is to just mark
|
|
each incoming one as not on a list. This can be seen in practice, for
|
|
example, with Qualcomm's rmnet_perf driver.
