2017-11-03Input: sparse-keymap - send sync event for KE_SW/KE_VSWStefan Brüns
Sync events are sent by sparse_keymap_report_entry for normal KEY_* events, and are generated by several drivers after generating SW_* events, so sparse_keymap_report_entry should do the same. Without the sync, events are accumulated in the kernel. Currently, no driver uses sparse-keymap for SW_* events, but it is required for the intel-vbtn platform driver to generate SW_TABLET_MODE events.

2017-11-03Input: cyttsp4 - avoid overflows when calculating memory sizesVince Kim
There are several places to perform subtraction to calculate buffer size such as: si->si_ofs.cydata_size = si->si_ofs.test_ofs - si->si_ofs.cydata_ofs; ... p = krealloc(si->si_ptrs.cydata, si->si_ofs.cydata_size, GFP_KERNEL); Actually, data types of above variables during subtraction are size_t, so it is unsigned. That means if second operand(si->si_ofs.cydata_ofs) is greater than the first operand(si->si_ofs.test_ofs), then resulting si->si_ofs.cydata_size could result in an unsigned integer wrap which is not desirable. The proper way to correct this problem is to perform a test of both operands to avoid having unsigned wrap.

2017-11-03xfs: truncate pagecache before writeback in xfs_setattr_size()Eryu Guan
On truncate down, if new size is not block size aligned, we zero the rest of block to avoid exposing stale data to user, and iomap_truncate_page() skips zeroing if the range is already in unwritten state or a hole. Then we writeback from on-disk i_size to the new size if this range hasn't been written to disk yet, and truncate page cache beyond new EOF and set in-core i_size. The problem is that we could write data between di_size and newsize before removing the page cache beyond newsize, as the extents may still be in unwritten state right after a buffer write. As such, the page of data that newsize lies in has not been zeroed by page cache invalidation before it is written, and xfs_do_writepage() hasn't triggered it's "zero data beyond EOF" case because we haven't updated in-core i_size yet. Then a subsequent mmap read could see non-zeros past EOF. I occasionally see this in fsx runs in fstests generic/112, a simplified fsx operation sequence is like (assuming 4k block size xfs): fallocate 0x0 0x1000 0x0 keep_size write 0x0 0x1000 0x0 truncate 0x0 0x800 0x1000 punch_hole 0x0 0x800 0x800 mapread 0x0 0x800 0x800 where fallocate allocates unwritten extent but doesn't update i_size, buffer write populates the page cache and extent is still unwritten, truncate skips zeroing page past new EOF and writes the page to disk, punch_hole invalidates the page cache, at last mapread reads the block back and sees non-zero beyond EOF. Fix it by moving truncate_setsize() to before writeback so the page cache invalidation zeros the partial page at the new EOF. This also triggers "zero data beyond EOF" in xfs_do_writepage() at writeback time, because newsize has been set and page straddles the newsize. Also fixed the wrong 'end' param of filemap_write_and_wait_range() call while we're at it, the 'end' is inclusive and should be 'newsize - 1'.

2017-11-03scsi: mpt3sas: Handle NVMe PCIe device related events generated from firmware.Suganath Prabu Subramani
* The controller firmware sends separate events for NVMe devices and PCIe switches similar to existing SAS events. * NVMe device detection, addition and removal are reported by the firmware through PCIe Topology Change list events. * The PCIe device state change events are sent when the firmware detects any abnormal conditions with a NVMe device or switch. * The enumeration event are sent when the firmware starts PCIe device enumeration and stops. * This patch has the code change to handle the events and add/remove NVMe devices in driver's inventory.
