2023-06-23drm/sysfs: rename drm_sysfs_connector_status_event()Simon Ser
Rename drm_sysfs_connector_status_event() to drm_sysfs_connector_property_event(). Indeed, "status" is a bit vague: it can easily be confused with the connected/disconnected status of the connector. This function has nothing to do with connected/disconnected: it merely sends a notification that a connector's property has changed (e.g. HDCP, privacy screen, etc).

2023-06-18ata: libata-scsi: Avoid deadlock on rescan after device resumeDamien Le Moal
When an ATA port is resumed from sleep, the port is reset and a power management request issued to libata EH to reset the port and rescanning the device(s) attached to the port. Device rescanning is done by scheduling an ata_scsi_dev_rescan() work, which will execute scsi_rescan_device(). However, scsi_rescan_device() takes the generic device lock, which is also taken by dpm_resume() when the SCSI device is resumed as well. If a device rescan execution starts before the completion of the SCSI device resume, the rcu locking used to refresh the cached VPD pages of the device, combined with the generic device locking from scsi_rescan_device() and from dpm_resume() can cause a deadlock. Avoid this situation by changing struct ata_port scsi_rescan_task to be a delayed work instead of a simple work_struct. ata_scsi_dev_rescan() is modified to check if the SCSI device associated with the ATA device that must be rescanned is not suspended. If the SCSI device is still suspended, ata_scsi_dev_rescan() returns early and reschedule itself for execution after an arbitrary delay of 5ms.

2023-06-15drm/dp_mst: Clear MSG_RDY flag before sending new messageWayne Lin
[Why] The sequence for collecting down_reply from source perspective should be: Request_n->repeat (get partial reply of Request_n->clear message ready flag to ack DPRX that the message is received) till all partial replies for Request_n are received->new Request_n+1. Now there is chance that drm_dp_mst_hpd_irq() will fire new down request in the tx queue when the down reply is incomplete. Source is restricted to generate interveleaved message transactions so we should avoid it. Also, while assembling partial reply packets, reading out DPCD DOWN_REP Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be wrapped up as a complete operation for reading out a reply packet. Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might be risky. e.g. If the reply of the new request has overwritten the DPRX DOWN_REP Sideband MSG buffer before source writing one to clear DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply for the new request. Should handle the up request in the same way. [How] Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might trigger drm_dp_mst_kick_tx() only when there is no on going message transaction. Changes since v1: * Reworked on review comments received -> Adjust the fix to let driver explicitly kick off new down request when mst irq event is handled and acked -> Adjust the commit message Changes since v2: * Adjust the commit message * Adjust the naming of the divided 2 functions and add a new input parameter "ack". * Adjust code flow as per review comments.

2023-06-15drm/amdkfd: bump kfd ioctl minor version for event age availabilityJames Zhu
Bump the minor version to declare event age tracking feature is now available. In kernel amdgpu driver, kfd_wait_on_events is used to support user space signal event wait function. For multiple threads waiting on same event scenery, race condition could occur since some threads after checking signal condition, before calling kfd_wait_on_events, the event interrupt could be fired and wake up other thread which are sleeping on this event. Then those threads could fall into sleep without waking up again. Adding event age tracking in both kernel and user mode, will help avoiding this race condition.

2023-06-14net/sched: qdisc_destroy() old ingress and clsact Qdiscs before graftingPeilin Ye
mini_Qdisc_pair::p_miniq is a double pointer to mini_Qdisc, initialized in ingress_init() to point to net_device::miniq_ingress. ingress Qdiscs access this per-net_device pointer in mini_qdisc_pair_swap(). Similar for clsact Qdiscs and miniq_egress. Unfortunately, after introducing RTNL-unlocked RTM_{NEW,DEL,GET}TFILTER requests (thanks Hillf Danton for the hint), when replacing ingress or clsact Qdiscs, for example, the old Qdisc ("@old") could access the same miniq_{in,e}gress pointer(s) concurrently with the new Qdisc ("@new"), causing race conditions [1] including a use-after-free bug in mini_qdisc_pair_swap() reported by syzbot: BUG: KASAN: slab-use-after-free in mini_qdisc_pair_swap+0x1c2/0x1f0 net/sched/sch_generic.c:1573 Write of size 8 at addr ffff888045b31308 by task syz-executor690/14901 ...

In other words, @old should never modify miniq_{in,e}gress after @new, and @new should not update @old's RCU state. Fixing without changing sch_api.c turned out to be difficult (please refer to Closes: for discussions). Instead, make sure @new's first call always happen after @old's last call (in {ingress,clsact}_destroy()) has finished: In qdisc_graft(), return -EBUSY if @old has any ongoing filter requests, and call qdisc_destroy() for @old before grafting @new. Introduce qdisc_refcount_dec_if_one() as the counterpart of qdisc_refcount_inc_nz() used for filter requests. Introduce a non-static version of qdisc_destroy() that does a TCQ_F_BUILTIN check, just like qdisc_put() etc. Depends on patch "net/sched: Refactor qdisc_graft() for ingress and clsact Qdiscs". [1] To illustrate, the syzkaller reproducer adds ingress Qdiscs under TC_H_ROOT (no longer possible after commit c7cfbd115001 ("net/sched: sch_ingress: Only create under TC_H_INGRESS")) on eth0 that has 8 transmission queues: Thread 1 creates ingress Qdisc A (containing mini Qdisc a1 and a2), then adds a flower filter X to A. Thread 2 creates another ingress Qdisc B (containing mini Qdisc b1 and b2) to replace A, then adds a flower filter Y to B. Thread 1 A's refcnt Thread 2 RTM_NEWQDISC (A, RTNL-locked) qdisc_create(A) 1 qdisc_graft(A) 9 RTM_NEWTFILTER (X, RTNL-unlocked) __tcf_qdisc_find(A) 10 tcf_chain0_head_change(A) mini_qdisc_pair_swap(A) (1st) | | RTM_NEWQDISC (B, RTNL-locked) RCU sync 2 qdisc_graft(B) | 1 notify_and_destroy(A) | tcf_block_release(A) 0 RTM_NEWTFILTER (Y, RTNL-unlocked) qdisc_destroy(A) tcf_chain0_head_change(B) tcf_chain0_head_change_cb_del(A) mini_qdisc_pair_swap(B) (2nd) mini_qdisc_pair_swap(A) (3rd) | ... ... Here, B calls mini_qdisc_pair_swap(), pointing eth0->miniq_ingress to its mini Qdisc, b1. Then, A calls mini_qdisc_pair_swap() again during ingress_destroy(), setting eth0->miniq_ingress to NULL, so ingress packets on eth0 will not find filter Y in sch_handle_ingress(). This is just one of the possible consequences of concurrently accessing miniq_{in,e}gress pointers.

2023-06-14net/sched: act_ct: Fix promotion of offloaded unreplied tuplePaul Blakey
Currently UNREPLIED and UNASSURED connections are added to the nf flow table. This causes the following connection packets to be processed by the flow table which then skips conntrack_in(), and thus such the connections will remain UNREPLIED and UNASSURED even if reply traffic is then seen. Even still, the unoffloaded reply packets are the ones triggering hardware update from new to established state, and if there aren't any to triger an update and/or previous update was missed, hardware can get out of sync with sw and still mark packets as new. Fix the above by: 1) Not skipping conntrack_in() for UNASSURED packets, but still refresh for hardware, as before the cited patch. 2) Try and force a refresh by reply-direction packets that update the hardware rules from new to established state. 3) Remove any bidirectional flows that didn't failed to update in hardware for re-insertion as bidrectional once any new packet arrives.

2023-06-11RDMA/mlx5: Fix affinity assignmentMark Bloch
The cited commit aimed to ensure that Virtual Functions (VFs) assign a queue affinity to a Queue Pair (QP) to distribute traffic when the LAG master creates a hardware LAG. If the affinity was set while the hardware was not in LAG, the firmware would ignore the affinity value. However, this commit unintentionally assigned an affinity to QPs on the LAG master's VPORT even if the RDMA device was not marked as LAG-enabled. In most cases, this was not an issue because when the hardware entered hardware LAG configuration, the RDMA device of the LAG master would be destroyed and a new one would be created, marked as LAG-enabled. The problem arises when a user configures Equal-Cost Multipath (ECMP). In ECMP mode, traffic can be directed to different physical ports based on the queue affinity, which is intended for use by VPORTS other than the E-Switch manager. ECMP mode is supported only if both E-Switch managers are in switchdev mode and the appropriate route is configured via IP. In this configuration, the RDMA device is not destroyed, and we retain the RDMA device that is not marked as LAG-enabled. To ensure correct behavior, Send Queues (SQs) opened by the E-Switch manager through verbs should be assigned strict affinity. This means they will only be able to communicate through the native physical port associated with the E-Switch manager. This will prevent the firmware from assigning affinity and will not allow the SQs to be remapped in case of failover.

2023-06-09drm/amdgpu: add new flag to AMDGPU_CTX_QUERY2Pierre-Eric Pelloux-Prayer
OpenGL EXT_robustness extension expects the driver to stop reporting GUILTY_CONTEXT_RESET when the reset has completed and the GPU is ready to accept submission again. This commit adds a AMDGPU_CTX_QUERY2_FLAGS_RESET_IN_PROGRESS flag, that let the UMD know that the reset is still not finished.

2023-06-08netfilter: nf_tables: integrate pipapo into commit protocolPablo Neira Ayuso
The pipapo set backend follows copy-on-update approach, maintaining one clone of the existing datastructure that is being updated. The clone and current datastructures are swapped via rcu from the commit step. The existing integration with the commit protocol is flawed because there is no operation to clean up the clone if the transaction is aborted. Moreover, the datastructure swap happens on set element activation. This patch adds two new operations for sets: commit and abort, these new operations are invoked from the commit and abort steps, after the transactions have been digested, and it updates the pipapo set backend to use it. This patch adds a new ->pending_update field to sets to maintain a list of sets that require this new commit and abort operations.
