[PATCH 1/2] drm: Add might_fault to drm_modeset_lock priming

[PATCH 1/2] drm: Add might_fault to drm_modeset_lock priming

[Daniel Vetter]

We already teach lockdep that dma_resv nests within drm_modeset_lock,
but there's a lot more: All drm kms ioctl rely on being able to
put/get_user while holding modeset locks, so we really need a
might_fault in there too to complete the picture. Add it.

Motivated by a syzbot report that blew up on bcachefs doing an
unconditional console_lock way deep in the locking hierarchy, and
lockdep only noticing the depency loop in a drm ioctl instead of much
earlier. This annotation will make sure such issues have a much harder
time escaping.

[PATCH 2/2] bcachefs: only console_trylock in bch2_print_string_as_lines

[Daniel Vetter]

console_lock is the outermost subsystem lock for a lot of subsystems,
which means get/put_user must nest within. Which means it cannot be
acquired somewhere deeply nested in other locks, and most definitely
not while holding fs locks potentially needed to resolve faults.

console_trylock is the best we can do here.

Including printk folks since even trylock feels realyl iffy here to
me.

Using the console lock here at all is wrong. The console lock does not
prevent other CPUs from calling printk() and inserting lines in between.

There is no way to guarantee a contiguous ringbuffer block using
multiple printk() calls.

The console_lock usage should be removed.

Mhm, lockdep should be able to deduce that when there might be faults 
under the dma_resv lock there might also be faults under the 
drm_modeset_lock.

On the other hand pointing it out explicitly doesn't hurts us at all, so

You're not allowed to take a fault under dma_resv, because drivers
might need to take that lock to handle faults. So unfortunately in our
combined lockdep priming, there really seems to be no chain yet that
teaches about faults possibly happening while holding
drm_modeset_lock.

Ah, of course! You are right, it was just the other way around.

Thanks,

[PATCH] bcachefs: no console_lock in bch2_print_string_as_lines

[Daniel Vetter]

console_lock is the outermost subsystem lock for a lot of subsystems,
which means get/put_user must nest within. Which means it cannot be
acquired somewhere deeply nested in other locks, and most definitely
not while holding fs locks potentially needed to resolve faults.

console_trylock is the best we can do here. But John pointed out on a
previous version that this is futile:

"Using the console lock here at all is wrong. The console lock does not
prevent other CPUs from calling printk() and inserting lines in between.

"There is no way to guarantee a contiguous ringbuffer block using
multiple printk() calls.

"The console_lock usage should be removed."

https://lore.kernel.org/lkml/87frsh33xp.fsf@jogness.linutronix.de/

Do that.

Note that there is more of this incorrect usage of console lock in:

fs/bcachefs/debug.c:bch2_btree_verify_replica()

fs/bcachefs/bset.c:bch2_dump_btree_node()

from commit 1c6fdbd8f246("bcachefs: Initial commit")

... and its parent bcache:

drivers/md/bcache/debug.c:bch_btree_verify()

drivers/md/bcache/bset.c:bch_dump_bucket()

from commit cafe56359144("bcache: A block layer cache")

These should also be removed. Although Kent should verify that the
console lock is not providing some sort of necessary side-effect
synchronization.
