The following changes since commit 830b3c68c1fb1e9176028d02ef86f3cf76aa2476: Linux 6.1 (2022-12-11 14:15:18 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git tags/for_linus for you to fetch changes up to 98dd6b2ef50d6f7876606a86c8d8a767c9fef6f5: virtio_blk: mark all zone fields LE (2022-12-22 14:32:36 -0500) Note: merging this upstream results in a conflict between commit: de4eda9de2d9 ("use less confusing names for iov_iter direction initializers") from Linus' tree and commit: ("virtio/vsock: replace virtio_vsock_pkt with sk_buff") from this tree. This resolution below fixes it up, due to Stephen Rothwell diff --cc drivers/vhost/vsock.c index cd6f7776013a,830bc823addc..000000000000 --- a/drivers/vhost/vsock.c +++ b/drivers/vhost/vsock.c @@@ -165,8 -157,9 +157,9 @@@ vhost_transport_do_send_pkt(struct vhos break; } - iov_iter_init(&iov_iter, READ, &vq->iov[out], in, iov_len); + iov_iter_init(&iov_iter, ITER_DEST, &vq->iov[out], in, iov_len); - payload_len = pkt->len - pkt->off; + payload_len = skb->len; + hdr = virtio_vsock_hdr(skb); /* If the packet is greater than the space available in the * buffer, we split it using multiple buffers. @@@ -366,18 -340,21 +340,22 @@@ vhost_vsock_alloc_skb(struct vhost_virt return NULL; } - pkt = kzalloc(sizeof(*pkt), GFP_KERNEL); - if (!pkt) + len = iov_length(vq->iov, out); + + /* len contains both payload and hdr */ + skb = virtio_vsock_alloc_skb(len, GFP_KERNEL); + if (!skb) return NULL; - iov_iter_init(&iov_iter, WRITE, vq->iov, out, len); + len = iov_length(vq->iov, out); + iov_iter_init(&iov_iter, ITER_SOURCE, vq->iov, out, len); - nbytes = copy_from_iter(&pkt->hdr, sizeof(pkt->hdr), &iov_iter); - if (nbytes != sizeof(pkt->hdr)) { + hdr = virtio_vsock_hdr(skb); + nbytes = copy_from_iter(hdr, sizeof(*hdr), &iov_iter); + if (nbytes != sizeof(*hdr)) { vq_err(vq, "Expected %zu bytes for pkt->hdr, got %zu bytes\n", - sizeof(pkt->hdr), nbytes); - kfree(pkt); + sizeof(*hdr), nbytes); + kfree_skb(skb); return NULL; } It can also be found in linux-next, see next-20221220. ---------------------------------------------------------------- virtio,vhost,vdpa: features, fixes, cleanups zoned block device support lifetime stats support (for virtio devices backed by memory supporting that) vsock rework to use skbuffs ifcvf features provisioning new SolidNET DPU driver Signed-off-by: Michael S.
