[PATCH RESEND] soundwire: stream: Revert "soundwire: stream: fix programming slave ports for non-continous port maps"

by Krzysztof Kozlowski

This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it breaks codecs using non-continuous masks in source and sink ports. The commit missed the point that port numbers are not used as indices for iterating over prop.sink_ports or prop.source_ports. Soundwire core and existing codecs expect that the array passed as prop.sink_ports and prop.source_ports is continuous. The port mask still might be non-continuous, but that's unrelated.

Follow-up to "net: drop bad gso csum_start and offset in virtio_net_hdr" - backport for 5.15 needed

by Christian Theune

Hi, the issue was so far handled in https://lore.kernel.org/regressions/ZsyMzW-4ee_U8NoX@eldamar.lan/T/#m390d6e… and https://bugzilla.kernel.org/show_bug.cgi?id=219129 I haven’t seen any communication whether a backport for 5.15 is already in progress, so I thought I’d follow up here. Today we rolled out 5.15.165 and immediately ran into the same issue. There’s at least one other person asking for a 5.15 backport in Bugzilla.

[PATCH v5 2/2] ufs: core: requeue aborted request

by peter.wang＠mediatek.com

From: Peter Wang <peter.wang(a)mediatek.com> ufshcd_abort_all forcibly aborts all on-going commands and the host controller will automatically fill in the OCS field of the corresponding response with OCS_ABORTED based on different working modes. MCQ mode: aborts a command using SQ cleanup, The host controller will post a Completion Queue entry with OCS = ABORTED. SDB mode: aborts a command using UTRLCLR. Task Management response which means a Transfer Request was aborted. For these two cases, set a flag to notify SCSI to requeue the command after receiving response with OCS_ABORTED.

[PATCH] fbdev/xen-fbfront: Assign fb_info->device

by Jason Andryuk

From: Jason Andryuk <jason.andryuk(a)amd.com> Probing xen-fbfront faults in video_is_primary_device(). The passed-in struct device is NULL since xen-fbfront doesn't assign it and the memory is kzalloc()-ed. Assign fb_info->device to avoid this.

[PATCH net] net: tighten bad gso csum offset check in virtio_net_hdr

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> The referenced commit drops bad input, but has false positives. Tighten the check to avoid these. The check detects illegal checksum offload requests, which produce csum_start/csum_off beyond end of packet after segmentation. But it is based on two incorrect assumptions: 1. virtio_net_hdr_to_skb with VIRTIO_NET_HDR_GSO_TCP[46] implies GSO. True in callers that inject into the tx path, such as tap. But false in callers that inject into rx, like virtio-net. Here, the flags indicate GRO, and CHECKSUM_UNNECESSARY or CHECKSUM_NONE without VIRTIO_NET_HDR_F_NEEDS_CSUM is normal. 2. TSO requires checksum offload, i.e., ip_summed == CHECKSUM_PARTIAL. False, as tcp[46]_gso_segment will fix up csum_start and offset for all other ip_summed by calling __tcp_v4_send_check. Because of 2, we can limit the scope of the fix to virtio_net_hdr that do try to set these fields, with a bogus value. Link: https://lore.kernel.org/netdev/20240909094527.GA3048202@port70.net/ Fixes: 89add40066f9 ("net: drop bad gso csum_start and offset in virtio_net_hdr") Signed-off-by: Willem de Bruijn <willemb(a)google.com> Cc: <stable(a)vger.kernel.net> --- Verified that the syzbot repro is still caught. An equivalent alternative would be to move the check for csum_offset to where the csum_start check is in segmentation: - if (unlikely(skb_checksum_start(skb) != skb_transport_header(skb))) + if (unlikely(skb_checksum_start(skb) != skb_transport_header(skb) || + skb->csum_offset != offsetof(struct tcphdr, check))) Cleaner, but messier stable backport. We'll need an equivalent patch to this for VIRTIO_NET_HDR_GSO_UDP_L4. But that csum_offset test was in a different commit, so different Fixes tag. --- include/linux/virtio_net.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/include/linux/virtio_net.h b/include/linux/virtio_net.h index 6c395a2600e8d..276ca543ef44d 100644 --- a/include/linux/virtio_net.h +++ b/include/linux/virtio_net.h @@ -173,7 +173,8 @@ static inline int virtio_net_hdr_to_skb(struct sk_buff *skb, break; case SKB_GSO_TCPV4: case SKB_GSO_TCPV6: - if (skb->csum_offset != offsetof(struct tcphdr, check)) + if (skb->ip_summed == CHECKSUM_PARTIAL && + skb->csum_offset != offsetof(struct tcphdr, check)) return -EINVAL; break; } -- 2.46.0.598.g6f2099f65c-goog

[PATCH v2 3/3] block: fix ordering between checking BLK_MQ_S_STOPPED and adding requests

by Muchun Song

Supposing first scenario with a virtio_blk driver. CPU0 CPU1 blk_mq_try_issue_directly() __blk_mq_issue_directly() q->mq_ops->queue_rq() virtio_queue_rq() blk_mq_stop_hw_queue() virtblk_done() blk_mq_request_bypass_insert() blk_mq_start_stopped_hw_queues() /* Add IO request to dispatch list */ 1) store blk_mq_start_stopped_hw_queue() clear_bit(BLK_MQ_S_STOPPED) 3) store blk_mq_run_hw_queue() blk_mq_run_hw_queue() if (!blk_mq_hctx_has_pending()) if (!blk_mq_hctx_has_pending()) 4) load return return blk_mq_sched_dispatch_requests() blk_mq_sched_dispatch_requests() if (blk_mq_hctx_stopped()) 2) load if (blk_mq_hctx_stopped()) return return __blk_mq_sched_dispatch_requests() __blk_mq_sched_dispatch_requests() Supposing another scenario. CPU0 CPU1 blk_mq_requeue_work() /* Add IO request to dispatch list */ 1) store virtblk_done() blk_mq_run_hw_queues()/blk_mq_delay_run_hw_queues() blk_mq_start_stopped_hw_queues() if (blk_mq_hctx_stopped()) 2) load blk_mq_start_stopped_hw_queue() continue clear_bit(BLK_MQ_S_STOPPED) 3) store blk_mq_run_hw_queue()/blk_mq_delay_run_hw_queue() blk_mq_run_hw_queue() if (!blk_mq_hctx_has_pending()) 4) load return blk_mq_sched_dispatch_requests() Both scenarios are similar, the full memory barrier should be inserted between 1) and 2), as well as between 3) and 4) to make sure that either CPU0 sees BLK_MQ_S_STOPPED is cleared or CPU1 sees dispatch list. Otherwise, either CPU will not rerun the hardware queue causing starvation of the request. The easy way to fix it is to add the essential full memory barrier into helper of blk_mq_hctx_stopped(). In order to not affect the fast path (hardware queue is not stopped most of the time), we only insert the barrier into the slow path. Actually, only slow path needs to care about missing of dispatching the request to the low-level device driver.

[PATCH v2 1/3] block: fix missing dispatching request when queue is started or unquiesced

by Muchun Song

Supposing the following scenario with a virtio_blk driver. CPU0 CPU1 CPU2 blk_mq_try_issue_directly() __blk_mq_issue_directly() q->mq_ops->queue_rq() virtio_queue_rq() blk_mq_stop_hw_queue() blk_mq_try_issue_directly() virtblk_done() if (blk_mq_hctx_stopped()) blk_mq_request_bypass_insert() blk_mq_start_stopped_hw_queue() blk_mq_run_hw_queue() blk_mq_run_hw_queue() blk_mq_insert_request() return // Who is responsible for dispatching this IO request? After CPU0 has marked the queue as stopped, CPU1 will see the queue is stopped. But before CPU1 puts the request on the dispatch list, CPU2 receives the interrupt of completion of request, so it will run the hardware queue and marks the queue as non-stopped. Meanwhile, CPU1 also runs the same hardware queue. After both CPU1 and CPU2 complete blk_mq_run_hw_queue(), CPU1 just puts the request to the same hardware queue and returns. It misses dispatching a request. Fix it by running the hardware queue explicitly. And blk_mq_request_issue_directly() should handle a similar situation. Fix it as well.
