2022-06-09mtd: st_spi_fsm: Warn about failure to unregister mtd deviceUwe Kleine-König
mtd_device_unregister() shouldn't fail. Wail loudly if it does anyhow. This matches how other drivers (e.g. nand/raw/nandsim.c) use mtd_device_unregister(). By returning 0 in the platform remove callback a generic error message by the device core is suppressed, nothing else changes. This is a preparation for making platform remove callbacks return void.

2022-06-09mtdchar: use kvmalloc() for potentially large allocationsMichał Kępień
mtdchar_write_ioctl() calls kmalloc() with the 'size' argument set to the smaller of two values: the write request's data/OOB length provided by user space and the erase block size of the MTD device. If the latter is large, kmalloc() may not be able to serve such allocation requests. Use kvmalloc() instead. Correspondingly, replace kfree() calls with kvfree() calls.

2022-06-09mtdchar: prevent integer overflow in a safety checkMichał Kępień
Commit 6420ac0af95d ("mtdchar: prevent unbounded allocation in MEMWRITE ioctl") added a safety check to mtdchar_write_ioctl() which attempts to ensure that the write request sent by user space does not extend beyond the MTD device's size. However, that check contains an addition of two struct mtd_write_req fields, 'start' and 'len', both of which are u64 variables. The result of that addition can overflow, allowing the safety check to be bypassed. The arguably simplest fix - changing the data types of the relevant struct mtd_write_req fields - is not feasible as it would break user space. Fix by making mtdchar_write_ioctl() truncate the value provided by user space in the 'len' field of struct mtd_write_req, so that only the lower 32 bits of that field are used, preventing the overflow. While the 'ooblen' field of struct mtd_write_req is not currently used in any similarly flawed safety check, also truncate it to 32 bits, for consistency with the 'len' field and with other MTD routines handling OOB data. Update include/uapi/mtd/mtd-abi.h accordingly.

2022-06-09mtd: sm_ftl: Fix deadlock caused by cancel_work_sync in sm_releaseDuoming Zhou
There is a deadlock between sm_release and sm_cache_flush_work which is a work item. The cancel_work_sync in sm_release will not return until sm_cache_flush_work is finished. If we hold mutex_lock and use cancel_work_sync to wait the work item to finish, the work item also requires mutex_lock. As a result, the sm_release will be blocked forever. The race condition is shown below: (Thread 1) | (Thread 2) sm_release | mutex_lock(&ftl->mutex) | sm_cache_flush_work | mutex_lock(&ftl->mutex) cancel_work_sync | ...

2022-06-05bluetooth: don't use bitmaps for random flag accessesLinus Torvalds
The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953fd221 ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
