2021-05-04xfs: don't allow log writes if the data device is readonlyDarrick J. Wong1-4/+6
While running generic/050 with an external log, I observed this warning in dmesg: Trying to write to read-only block-device sda4 (partno 4) WARNING: CPU: 2 PID: 215677 at block/blk-core.c:704 submit_bio_checks+0x256/0x510 Call Trace: submit_bio_noacct+0x2c/0x430 _xfs_buf_ioapply+0x283/0x3c0 [xfs] __xfs_buf_submit+0x6a/0x210 [xfs] xfs_buf_delwri_submit_buffers+0xf8/0x270 [xfs] xfsaild+0x2db/0xc50 [xfs] kthread+0x14b/0x170 I think this happened because we tried to cover the log after a readonly mount, and the AIL tried to write the primary superblock to the data device. The test marks the data device readonly, but it doesn't do the same to the external log device. Therefore, XFS thinks that the log is writable, even though AIL writes whine to dmesg because the data device is read only. Fix this by amending xfs_log_writable to prevent writes when the AIL can't possible write anything into the filesystem. Note: As for the external log or the rt devices being readonly-- xfs_blkdev_get will complain about that if we aren't doing a norecovery mount. Signed-off-by: Darrick J.

Commit 7c95d8893fb5 ("powerpc: Change calling convention for create_branch() et. al.") complexified the frame of function do_feature_fixups(), leading to GCC setting up a stack guard when CONFIG_STACKPROTECTOR is selected. The problem is that do_feature_fixups() is called very early while 'current' in r2 is not set up yet and the code is still not at the final address used at link time. So, like other instrumentation, stack protection needs to be deactivated for feature-fixups.c and code-patching.c Fixes: 7c95d8893fb5 ("powerpc: Change calling convention for create_branch() et. al.")

2021-05-04powerpc/kexec_file: Use current CPU info while setting up FDTSourabh Jain1-0/+92
kexec_file_load() uses initial_boot_params in setting up the device tree for the kernel to be loaded. Though initial_boot_params holds info about CPUs at the time of boot, it doesn't account for hot added CPUs. So, kexec'ing with kexec_file_load() syscall leaves the kexec'ed kernel with inaccurate CPU info. If kdump kernel is loaded with kexec_file_load() syscall and the system crashes on a hot added CPU, the capture kernel hangs failing to identify the boot CPU, with no output. To avoid this from happening, extract current CPU info from of_root device node and use it for setting up the fdt in kexec_file_load case.

2021-05-04ALSA: hda/realtek: Fix speaker amp on HP Envy AiO 32Takashi Iwai1-0/+35
HP Envy AiO 32-a12xxx has an external amp that is controlled via GPIO bit 0x04. However, unlike other devices, this amp seems to shut down itself after the certain period, hence the OS needs to up/down the bit dynamically only during the actual playback. This patch adds the control of the GPIO bit via the existing pcm_hook mechanism. Ideally it should be triggered at the actual stream start, but we have only the state change at prepare/cleanup, so use those for switching the GPIO bit on/off. This should be good enough for the purpose, and was actually confirmed to work fine.

2021-05-04nvme-multipath: reset bdev to ns head when failoverDaniel Wagner1-0/+3
When a request finally completes in end_io() after it has failed over, the bdev pointer can be stale and thus the system can crash. Set the bdev back to ns head, so the request is map to an active path when resubmitted.

2021-05-04nvme-pci: fix controller reset hang when racing with nvme_timeoutTao Chiu1-0/+3
reset_work() in nvme-pci may hang forever in the following scenario: 1) A reset caused by a command timeout occurs due to a controller being temporarily irresponsive. 2) nvme_reset_work() restarts admin queue at nvme_alloc_admin_tags(). At the same time, a user-submitted admin command is queued and waiting for completion. Then, reset_work() changes its state to CONNECTING, and submits an identify command. 3) However, the controller does still not respond to any command, causing a timeout being fired at the user-submitted command. Unfortunately, nvme_timeout() does not see the completion on cq, and any timeout that takes place under CONNECTING state causes a controller shutdown. 4) Normally, the identify command in reset_work() would be canceled with SC_HOST_ABORTED by nvme_dev_disable(), then reset_work can tear down the controller accordingly. But the controller happens to return online and respond the identify command before nvme_dev_disable() should have been reaped it off. 5) reset_work() continues to setup_io_queues() as it observes no error in init_identify(). However, the admin queue has already been quiesced in dev_disable(). Thus, any following commands would be blocked forever in blk_execute_rq(). This can be fixed by restricting usercmd commands when controller is not in a LIVE state in nvme_queue_rq(), as what has been done previously in fabrics. ``` nvme_reset_work(): | nvme_alloc_admin_tags() | | nvme_submit_user_cmd(): nvme_init_identify(): | ... __nvme_submit_sync_cmd(): | ... | ... ---------------------------------------> nvme_timeout(): (Controller starts reponding commands) | nvme_dev_disable(, true): nvme_setup_io_queues(): | __nvme_submit_sync_cmd(): | (hung in blk_execute_rq | since run_hw_queue sees | queue quiesced) | ``` Signed-off-by: Tao Chiu <[email protected]> Signed-off-by: Cody Wong <[email protected]> Reviewed-by: Leon Chien <[email protected]> Reviewed-by: Keith Busch <[email protected]> Signed-off-by: Christoph Hellwig <[email protected]>
2021-05-04nvme: move the fabrics queue ready check routines to coreTao Chiu8-78/+83
queue_rq() in pci only checks if the dispatched queue (nvmeq) is ready, e.g. not being suspended. Since nvme_alloc_admin_tags() in reset flow restarts the admin queue, users are able to submit admin commands to a controller before reset_work() completes. Commands submitted under this condition may interfere with commands that performs identify, IO queue setup in reset_work(), and may result in a hang described in the following patch. As seen in the fabrics, user commands are prevented from being executed under inproper controller states. We may reuse this logic to maintain a clear admin queue during reset_work().

2021-05-04nvme: avoid memset for passthrough requestsKanchan Joshi1-4/+3
nvme_clear_nvme_request() clears the nvme_command, which is unncessary for passthrough requests as nvme_command is overwritten immediately. Move clearing part from this helper to the caller, so that double memset for passthrough requests is avoided.
