[PATCH AUTOSEL 6.6 01/15] drm/fb-helper: Don't schedule_work() to flush frame buffer during panic()
From: Qiuxu Zhuo qiuxu.zhuo@intel.com
[ Upstream commit 833cd3e9ad8360785b6c23c82dd3856df00732d9 ]
Sometimes the system [1] hangs on x86 I/O machine checks. However, the expected behavior is to reboot the system, as the machine check handler ultimately triggers a panic(), initiating a reboot in the last step.
The root cause is that sometimes the panic() is blocked when drm_fb_helper_damage() invoking schedule_work() to flush the frame buffer. This occurs during the process of flushing all messages to the frame buffer driver as shown in the following call trace:
Machine check occurs [2]: panic() console_flush_on_panic() console_flush_all() console_emit_next_record() con->write() vt_console_print() hide_cursor() vc->vc_sw->con_cursor() fbcon_cursor() ops->cursor() bit_cursor() soft_cursor() info->fbops->fb_imageblit() drm_fbdev_generic_defio_imageblit() drm_fb_helper_damage_area() drm_fb_helper_damage() schedule_work() // <--- blocked here ... emergency_restart() // wasn't invoked, so no reboot.
During panic(), except the panic CPU, all the other CPUs are stopped. In schedule_work(), the panic CPU requires the lock of worker_pool to queue the work on that pool, while the lock may have been token by some other stopped CPU. So schedule_work() is blocked.
Additionally, during a panic(), since there is no opportunity to execute any scheduled work, it's safe to fix this issue by skipping schedule_work() on 'oops_in_progress' in drm_fb_helper_damage().
[1] Enable the kernel option CONFIG_FRAMEBUFFER_CONSOLE, CONFIG_DRM_FBDEV_EMULATION, and boot with the 'console=tty0' kernel command line parameter.
[2] Set 'panic_timeout' to a non-zero value before calling panic().

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB mode unconditionally even when the LSDBS of device HCI cap is 1. This makes commands time out and causes device probing to fail.
To prevent that problem, check the LSDBS cap when MCQ is not supported.

[CORRUPTION] There is a bug report that btrfs flips RO due to a corruption in the extent tree, the involved dumps looks like this:
item 188 key (402811572224 168 4096) itemoff 14598 itemsize 79 extent refs 3 gen 3678544 flags 1 ref#0: extent data backref root 13835058055282163977 objectid 281473384125923 offset 81432576 count 1 ref#1: shared data backref parent 1947073626112 count 1 ref#2: shared data backref parent 1156030103552 count 1 BTRFS critical (device vdc1: state EA): unable to find ref byte nr 402811572224 parent 0 root 265 owner 28703026 offset 81432576 slot 189 BTRFS error (device vdc1: state EA): failed to run delayed ref for logical 402811572224 num_bytes 4096 type 178 action 2 ref_mod 1: -2
[CAUSE] The corrupted entry is ref#0 of item 188. The root number 13835058055282163977 is beyond the upper limit for root items (the current limit is 1 << 48), and the objectid also looks suspicious.
Only the offset and count is correct.
[ENHANCEMENT] Although it's still unknown why we have such many bytes corrupted randomly, we can still enhance the tree-checker for data backrefs by:
- Validate the root value For now there should only be 3 types of roots can have data backref: * subvolume trees * data reloc trees * root tree Only for v1 space cache
- validate the objectid value The objectid should be a valid inode number.
Hopefully we can catch such problem in the future with the new checkers.

Some devices indicate click noises at suspend or shutdown when the speakers are unmuted. This patch adds a helper, snd_hda_gen_shutup_speakers(), to work around it. The new function is supposed to be called at suspend or shutdown by the codec driver, and it mutes the speakers.
The mute status isn't cached, hence the original mute state will be restored at resume again.

The UMP 1.1 spec says that an RPN/NRPN should be sent when one of the following occurs: * a CC 38 is received * a subsequent CC 6 is received * a CC 98, 99, 100, and 101 is received, indicating the last RPN/NRPN message has ended and a new one has started
That said, we should send a partial data even if it's not fully filled. Let's change the UMP conversion helper code to follow that rule.

The UMP core conversion helper API already defines the context needed to record the bank and RPN/NRPN values, and we can simply re-use the same struct instead of re-defining the same content as a different name.

This patch reduces the size of hw_ste_arr_optimized array that is allocated on stack from 640 bytes (5 match STEs + 5 action STES) to 448 bytes (2 match STEs + 5 action STES). This fixes the 'stack guard page was hit' issue, while still fitting majority of the usecases (up to 2 match STEs).

NetApp server requires the file to be open with FILE_READ_EA access in order to support FSCTL_GET_REPARSE_POINT, otherwise it will return STATUS_INVALID_DEVICE_REQUEST. It doesn't make any sense because there's no requirement for FILE_READ_EA bit to be set nor STATUS_INVALID_DEVICE_REQUEST being used for something other than "unsupported reparse points" in MS-FSA.
To fix it and improve compatibility, set FILE_READ_EA & SYNCHRONIZE bits to match what Windows client currently does.
