2023-06-09s390/dasd: Use correct lock while counting channel queue lengthJan Höppner1-2/+2
The lock around counting the channel queue length in the BIODASDINFO ioctl was incorrectly changed to the dasd_block->queue_lock with commit 583d6535cb9d ("dasd: remove dead code"). This can lead to endless list iterations and a subsequent crash. The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used. Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.

2023-06-09tools/virtio: use canonical ftrace pathRoss Zwisler2-5/+9
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.

2023-06-09drm/msm/dp: enable HDP plugin/unplugged interrupts at hpd_enable/disableKuogee Hsieh3-54/+35
The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller case. HDP related interrupts can not be enabled until internal_hpd is set to true. At current implementation dp_display_config_hpd() will initialize DP host controller first followed by enabling HDP related interrupts if internal_hpd was true at that time. Enable HDP related interrupts depends on internal_hpd status may leave system with DP driver host is in running state but without HDP related interrupts being enabled. This will prevent external display from being detected. Eliminated this dependency by moving HDP related interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly regardless of internal_hpd status.

2023-06-08vhost: Fix worker hangs due to missed wake up callsMike Christie2-7/+11
We can race where we have added work to the work_list, but vhost_task_fn has passed that check but not yet set us into TASK_INTERRUPTIBLE. wake_up_process will see us in TASK_RUNNING and just return. This bug was intoduced in commit f9010dbdce91 ("fork, vhost: Use CLONE_THREAD to fix freezer/ps regression") when I moved the setting of TASK_INTERRUPTIBLE to simplfy the code and avoid get_signal from logging warnings about being in the wrong state. This moves the setting of TASK_INTERRUPTIBLE back to before we test if we need to stop the task to avoid a possible race there as well. We then have vhost_worker set TASK_RUNNING if it finds work similar to before.

2023-06-08vhost: Fix crash during early vhost_transport_send_pkt callsMike Christie2-34/+18
If userspace does VHOST_VSOCK_SET_GUEST_CID before VHOST_SET_OWNER we can race where: 1. thread0 calls vhost_transport_send_pkt -> vhost_work_queue 2. thread1 does VHOST_SET_OWNER which calls vhost_worker_create. 3. vhost_worker_create will set the dev->worker pointer before setting the worker->vtsk pointer. 4. thread0's vhost_work_queue will see the dev->worker pointer is set and try to call vhost_task_wake using not yet set worker->vtsk pointer. 5. We then crash since vtsk is NULL. Before commit 6e890c5d5021 ("vhost: use vhost_tasks for worker threads"), we only had the worker pointer so we could just check it to see if VHOST_SET_OWNER has been done. After that commit we have the vhost_worker and vhost_task pointer, so we can now hit the bug above. This patch embeds the vhost_worker in the vhost_dev and moves the work list initialization back to vhost_dev_init, so we can just check the worker.vtsk pointer to check if VHOST_SET_OWNER has been done like before.

2023-06-08ext4: only check dquot_initialize_needed() when debuggingTheodore Ts'o1-2/+4
ext4_xattr_block_set() relies on its caller to call dquot_initialize() on the inode. To assure that this has happened there are WARN_ON checks. Unfortunately, this is subject to false positives if there is an antagonist thread which is flipping the file system at high rates between r/o and rw. So only do the check if EXT4_XATTR_DEBUG is enabled. Link: https://lore.kernel.org/r/20230608044056.GA1418535@mit.edu Signed-off-by: Theodore Ts'o <tytso@mit.edu>

2023-06-08bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacksSomnath Kotur1-7/+18
As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

2023-06-08bnxt_en: Prevent kernel panic when receiving unexpected PHC_UPDATE eventPavan Chebbi2-0/+7
The firmware can send PHC_RTC_UPDATE async event on a PF that may not have PTP registered. In such a case, there will be a null pointer deference for bp->ptp_cfg when we try to handle the event. Fix it by not registering for this event with the firmware if !bp->ptp_cfg. Also, check that bp->ptp_cfg is valid before proceeding when we receive the event.

2023-06-08bnxt_en: Query default VLAN before VNIC setup on a VFSomnath Kotur1-0/+3
We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.
