Subject: [PATCH net-next v2 00/12] vsock/virtio: continue MSG_ZEROCOPY support
Date: Sun, 1 Oct 2023 00:02:56 +0300 [thread overview]
Message-ID: <20230930210308.2394919-1-avkrasnov@salutedevices.com> (raw)
Hello,
this patchset contains second and third parts of another big patchset
for MSG_ZEROCOPY flag support:
https://lore.kernel.org/netdev/20230701063947.3422088-1-AVKrasnov@sberdevices.ru/
During review of this series, Stefano Garzarella <sgarzare@redhat.com>
suggested to split it for three parts to simplify review and merging:
1) virtio and vhost updates (for fragged skbs) (merged to net-next, see
link below)
2) AF_VSOCK updates (allows to enable MSG_ZEROCOPY mode and read
tx completions) and update for Documentation/. <-- this patchset
3) Updates for tests and utils. <-- this patchset
Part 1) was merged:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=71b263e79370348349553ecdf46f4a69eb436dc7
Head for this patchset is:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=236f3873b517acfaf949c23bb2d5dec13bfd2da2
Link to v1:
https://lore.kernel.org/netdev/20230922052428.4005676-1-avkrasnov@salutedevices.com/
Changelog:
v1 -> v2:
* Patchset rebased and tested on new HEAD of net-next (see hash above).
* See per-patch changelog after ---.
