Currently function stv090x_setup_compound also frees the state object too, leading to a double free in the callers of this function.

2019-06-13mm/devm_memremap_pages: fix final page put raceDan Williams
Logan noticed that devm_memremap_pages_release() kills the percpu_ref drops all the page references that were acquired at init and then immediately proceeds to unplug, arch_remove_memory(), the backing pages for the pagemap. If for some reason device shutdown actually collides with a busy / elevated-ref-count page then arch_remove_memory() should be deferred until after that reference is dropped. As it stands the "wait for last page ref drop" happens *after* devm_memremap_pages_release() returns, which is obviously too late and can lead to crashes. Fix this situation by assigning the responsibility to wait for the percpu_ref to go idle to devm_memremap_pages() with a new ->cleanup() callback. Implement the new cleanup callback for all devm_memremap_pages() users: pmem, devdax, hmm, and p2pdma.

2019-06-13PCI/P2PDMA: fix the gen_pool_add_virt() failure pathDan Williams
The pci_p2pdma_add_resource() implementation immediately frees the pgmap if gen_pool_add_virt() fails. However, that means that when @dev triggers a devres release devm_memremap_pages_release() will crash trying to access the freed @pgmap. Use the new devm_memunmap_pages() to manually free the mapping in the error path.

2019-06-13drivers/base/devres: introduce devm_release_action()Dan Williams
Patch series "mm/devm_memremap_pages: Fix page release race", v2. Logan audited the devm_memremap_pages() shutdown path and noticed that it was possible to proceed to arch_remove_memory() before all potential page references have been reaped. Introduce a new ->cleanup() callback to do the work of waiting for any straggling page references and then perform the percpu_ref_exit() in devm_memremap_pages_release() context. For p2pdma this involves some deeper reworks to reference count resources on a per-instance basis rather than a per pci-device basis. A modified genalloc api is introduced to convey a driver-private pointer through gen_pool_{alloc,free}() interfaces. Also, a devm_memunmap_pages() api is introduced since p2pdma does not auto-release resources on a setup failure. The dax and pmem changes pass the nvdimm unit tests, and the p2pdma changes should now pass testing with the pci_p2pdma_release() fix. Jrme, how does this look for HMM? This patch (of 6): The devm_add_action() facility allows a resource allocation routine to add custom devm semantics. One such user is devm_memremap_pages(). There is now a need to manually trigger devm_memremap_pages_release(). Introduce devm_release_action() so the release action can be triggered via a new devm_memunmap_pages() api in a follow-on change.

2019-06-13bcache: only set BCACHE_DEV_WB_RUNNING when cached device attachedColy Li
When people set a writeback percent via sysfs file, /sys/block/bcache<N>/bcache/writeback_percent current code directly sets BCACHE_DEV_WB_RUNNING to dc->disk.flags and schedules kworker dc->writeback_rate_update. If there is no cache set attached to, the writeback kernel thread is not running indeed, running dc->writeback_rate_update does not make sense and may cause NULL pointer deference when reference cache set pointer inside update_writeback_rate(). This patch checks whether the cache set point (dc->disk.c) is NULL in sysfs interface handler, and only set BCACHE_DEV_WB_RUNNING and schedule dc->writeback_rate_update when dc->disk.c is not NULL (it means the cache device is attached to a cache set). This problem might be introduced from initial bcache commit, but commit 3fd47bfe55b0 ("bcache: stop dc->writeback_rate_update properly") changes part of the original code piece, so I add 'Fixes: 3fd47bfe55b0' to indicate from which commit this patch can be applied.

2019-06-13bcache: fix stack corruption by PRECEDING_KEY()Coly Li
Recently people report bcache code compiled with gcc9 is broken, one of the buggy behavior I observe is that two adjacent 4KB I/Os should merge into one but they don't. Finally it turns out to be a stack corruption caused by macro PRECEDING_KEY(). See how PRECEDING_KEY() is defined in bset.h, 437 #define PRECEDING_KEY(_k) \ 438 ({ \ 439 struct bkey *_ret = NULL; \ 440 \ 441 if (KEY_INODE(_k) || KEY_OFFSET(_k)) { \ 442 _ret = &KEY(KEY_INODE(_k), KEY_OFFSET(_k), 0); \ 443 \ 444 if (!_ret->low) \ 445 _ret->high--; \ 446 _ret->low--; \ 447 } \ 448 \ 449 _ret; \ 450 }) At line 442, _ret points to address of a on-stack variable combined by KEY(), the life range of this on-stack variable is in line 442-446, once _ret is returned to bch_btree_insert_key(), the returned address points to an invalid stack address and this address is overwritten in the following called bch_btree_iter_init(). Then argument 'search' of bch_btree_iter_init() points to some address inside stackframe of bch_btree_iter_init(), exact address depends on how the compiler allocates stack space. Now the stack is corrupted.

2019-06-13null_blk: remove duplicate check for report zoneChaitanya Kulkarni
This patch removes the check in the null_blk_zoned for report zone command, where it checks for the dev-,>zoned before executing the report zone. The null_zone_report() function is a block_device operation callback which is initialized in the null_blk_main.c and gets called as a part of blkdev for report zone IOCTL (BLKREPORTZONE). blkdev_ioctl() blkdev_report_zones_ioctl() blkdev_report_zones() blk_report_zones() disk->fops->report_zones() nullb_zone_report(); The null_zone_report() will never get executed on the non-zoned block device, in the non zoned block device blk_queue_is_zoned() will always be false which is first check the blkdev_report_zones_ioctl() before actual low level driver report zone callback is executed. Here is the detailed scenario:- 1. modprobe null_blk null_init null_alloc_dev dev->zoned = 0 null_add_dev dev->zoned == 0 so we don't set the q->limits.zoned = BLK_ZONED_HR 2. blkzone report /dev/nullb0 blkdev_ioctl() blkdev_report_zones_ioctl() blk_queue_is_zoned() blk_queue_is_zoned q->limits.zoned == 0 return false if (!blk_queue_is_zoned(q)) <--- true return -ENOTTY; Reviewed-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Bob Liu <bob.liu@oracle.com> Signed-off-by: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
