2023-07-27staging: Explicitly include correct DT includesRob Herring14-17/+7
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

In order to avoid disturbing anything drop the initial fixes and fall back to a point fix in the SMBus code where the issue was originally noticed, a more substantial refactoring of the API which ensures that all buses make the same assumptions will follow. - The generic regcache code had been forcing on async I/O which did not work with the new maple tree sync code when used with SPI. Since that was mainly for the rbtree cache and the assumptions about hardware that drove the choice are probably not true any more fix this by pushing the enablement of async down into the rbtree code. This probably also makes cache syncs for systems faster though it's not the point. - The test code was triggering use of the rbtree and maple tree caches with dynamic allocation of nodes since all the testing is with RAM backed caches with no I/O performance issues. Just disable the locking in the tests to avoid triggering warnings when allocation debugging is turned on, it's not really what's being tested" * tag 'regmap-fix-v6.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Disable locking for RBTREE and MAPLE unit tests regcache: Push async I/O request down into the rbtree cache regmap: Account for register length in SMBus I/O limits regmap: Drop initial version of maximum transfer length fixes

2023-07-21loop: do not enforce max_loop hard limit by (new) defaultMauricio Faria de Oliveira1-2/+34
Problem: The max_loop parameter is used for 2 different purposes: 1) initial number of loop devices to pre-create on init 2) maximum number of loop devices to add on access/open() Historically, its default value (zero) caused 1) to create non-zero number of devices (CONFIG_BLK_DEV_LOOP_MIN_COUNT), and no hard limit on 2) to add devices with autoloading. However, the default value changed in commit 85c50197716c ("loop: Fix the max_loop commandline argument treatment when it is set to 0") to CONFIG_BLK_DEV_LOOP_MIN_COUNT, for max_loop=0 not to pre-create devices. That does improve 1), but unfortunately it breaks 2), as the default behavior changed from no-limit to hard-limit. Example: For example, this userspace code broke for N >= CONFIG, if the user relied on the default value 0 for max_loop: mknod("/dev/loopN"); open("/dev/loopN"); // now fails with ENXIO Though affected users may "fix" it with (loop.)max_loop=0, this means to require a kernel parameter change on stable kernel update (that commit Fixes: an old commit in stable). Solution: The original semantics for the default value in 2) can be applied if the parameter is not set (ie, default behavior). This still keeps the intended function in 1) and 2) if set, and that commit's intended improvement in 1) if max_loop=0. Before 85c50197716c: - default: 1) CONFIG devices 2) no limit - max_loop=0: 1) CONFIG devices 2) no limit - max_loop=X: 1) X devices 2) X limit After 85c50197716c: - default: 1) CONFIG devices 2) CONFIG limit (*) - max_loop=0: 1) 0 devices (*) 2) no limit - max_loop=X: 1) X devices 2) X limit This commit: - default: 1) CONFIG devices 2) no limit (*) - max_loop=0: 1) 0 devices 2) no limit - max_loop=X: 1) X devices 2) X limit Future: The issue/regression from that commit only affects code under the CONFIG_BLOCK_LEGACY_AUTOLOAD deprecation guard, thus the fix too is contained under it. Once that deprecated functionality/code is removed, the purpose 2) of max_loop (hard limit) is no longer in use, so the module parameter description can be changed then.

2023-07-21drm/atomic: Fix potential use-after-free in nonblocking commitsDaniel Vetter1-1/+10
This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.
