NetBSD thinkpad 10.0_RC2 NetBSD 10.0_RC2 (GENERIC) #0: Mon Jan 1 14:04:52 UTC 2024 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
I put a microSD card in a microSD to SD card adapter and put it in the SD slot on my computer. I wrote an ISO image to it. I then tried to unmount the disk with
umount /mnt
but the umount program hung. It was stuck in a tstile state and information from various commands related to this state are in the output of crash(8) below.
There is also a small typo in the sdmmc dmesg error string where a newline character is missing. See the dmesg output below for an instance of that message.
thinkpad# crash
Crash version 10.0_RC2, image version 10.0_RC2.
Kernel compiled without options LOCKDEBUG.
Output from a running system is unreliable.

>How-To-Repeat:
It's not known exactly how the system got into the state in the first place, but what looks like the same state can be entered by removing the SD card from the slot and then putting it back. Any command that needs information from the drive, like ls /mnt, disklabel ld0 or umount /mnt, will then hang, often in an unkillable state. It's true, however, that before the first umount hang occurred, I did remove the SD card from the slot and re-insert it back into the slot. I do not remember what state the system considered the SD card to be in, but it is possible that I removed the card in an improper state like the reproducability procedure above.
Also, although there are console messages printed when the SD card is removed when it is not mounted, there are no console messages printed when the SD card is removed when it IS mounted. This suggests that the removal of the SD card is not being detected.

I should clarify that the problem shows up when the SD card is removed =
and then reinserted WHILE the disk is mounted. If the SD card is not =
mounted, no issue arises. So the following sequence
mount /dev/ld0a /mnt
#remove SD card
#reinsert SD card
umount /mnt # or disklabel sd0 or ls /mnt
hangs, while
#remove SD card
#reinsert SD card
does not.=

deadlock in sdmmc task queue
happens because DIOCCACHESYNC starts task and waits for it,
and detach triggers DIOCCACHESYNC,
and discovery triggering detach runs through task queue,
so finishing discovery task requires waiting for cache sync task,
but cache sync task can't start until prior tasks finish.
Fix: separate threads for discovery and tasks.

Subject: [PATCH] ld@sdmmc(4): Hack around deadlock in cache sync on detach.
Yanking a card triggers the sdmmc discovery task, which runs in the
sdmmc task thread, to detach any attached child devices.
Detaching ld@sdmmc triggers a cache flush (via ldbegindetach ->
disk_begindetach -> ld_lastclose -> ld_flush -> ioctl DIOCCACHESYNC),
which is implemented by scheduling a task to do sdmmc_mem_flush_cache
and then waiting for it to complete.
The sdmmc_mem_cache_flush is done by an sdmmc task so it happens
after all previously scheduled I/O operations -- that way the cache
flush doesn't complete until the previously scheduled I/O operations
are complete.
However, when the cache flush task is issued from the discovery task,
this doesn't work, because the cache flush task can't start until the
discovery task has returned -- but the discovery task won't return
until the cache flush task has completed.
To work around this deadlock, which usually happens only when the
device has been yanked anyway so further I/O would be lost anyway,
just do the cache flush synchronously in DIOCCACHESYNC if we're
running in the task thread.
This isn't quite right -- implementation details of the task thread
shouldn't bleed into ld@sdmmc, and running the cache sync _before_
any subsequently scheduled I/O tasks is asking for trouble -- but it
should serve to avoid the deadlock in PR kern/57870 until we can fix
a host of concurrency bugs in sdmmc by fixing the locking scheme and
running discovery in a separate thread from tasks.

The patch appears to work. The process no longer hangs when the SD card =
is removed while it is mounted. The patched kernel did hang on startup =
the first time I booted it up but I didn't manage to reproduce that on =
the next few boots. The last thing it printed was "Starting xdm." The =
fan was going so it may have been dumping core, but I didn't consider =
that and forcibly rebooted after a minute or two had passed, but perhaps =
that was not enough time. I would guess that this boot hang is unrelated =
to the SD card issue.

Yanking a card triggers the sdmmc discovery task, which runs in the
sdmmc task thread, to detach any attached child devices.
Detaching ld@sdmmc triggers a cache flush (via ldbegindetach ->
disk_begindetach -> ld_lastclose -> ld_flush -> ioctl DIOCCACHESYNC),
which is implemented by scheduling a task to do sdmmc_mem_flush_cache
and then waiting for it to complete.
The sdmmc_mem_cache_flush is done by an sdmmc task so it happens
after all previously scheduled I/O operations -- that way the cache
flush doesn't complete until the previously scheduled I/O operations
are complete.
However, when the cache flush task is issued from the discovery task,
this doesn't work, because the cache flush task can't start until the
discovery task has returned -- but the discovery task won't return
until the cache flush task has completed.
To work around this deadlock, which usually happens only when the
device has been yanked anyway so further I/O would be lost anyway,
just do the cache flush synchronously in DIOCCACHESYNC if we're
running in the task thread.
This isn't quite right -- implementation details of the task thread
shouldn't bleed into ld@sdmmc, and running the cache sync _before_
any subsequently scheduled I/O tasks is asking for trouble -- but it
should serve to avoid the deadlock in PR kern/57870 until we can fix
a host of concurrency bugs in sdmmc by fixing the locking scheme and
running discovery in a separate thread from tasks.

ld@sdmmc(4): Hack around deadlock in cache sync on detach.
Yanking a card triggers the sdmmc discovery task, which runs in the
sdmmc task thread, to detach any attached child devices.
Detaching ld@sdmmc triggers a cache flush (via ldbegindetach ->

The sdmmc_mem_cache_flush is done by an sdmmc task so it happens
