2019-08-01drm/i915: Only recover active enginesChris Wilson
If we issue a reset to a currently idle engine, leave it idle afterwards. This is useful to excise a linkage between reset and the shrinker. When waking the engine, we need to pin the default context image which we use for overwriting a guilty context -- if the engine is idle we do not need this pinned image! However, this pinning means that waking the engine acquires the FS_RECLAIM, and so may trigger the shrinker. The shrinker itself may need to wait upon the GPU to unbind and object and so may require services of reset; ergo we should avoid the engine wake up path. The danger in skipping the recovery for idle engines is that we leave the engine with no context defined, which may interfere with the operation of the power context on some older platforms. In practice, we should only be resetting an active GPU but it something to look out for on Ironlake (if memory serves).

Since the reset path wants to recover the engines itself, it only wants to reinitialise the hardware using i915_gem_init_hw().

2019-08-01xen/swiotlb: remember having called xen_create_contiguous_region()Juergen Gross
Instead of always calling xen_destroy_contiguous_region() in case the memory is DMA-able for the used device, do so only in case it has been made DMA-able via xen_create_contiguous_region() before. This will avoid a lot of xen_destroy_contiguous_region() calls for 64-bit capable devices. As the memory in question is owned by swiotlb-xen the PG_owner_priv_1 flag of the first allocated page can be used for remembering.

2019-08-01xen/swiotlb: fix condition for calling xen_destroy_contiguous_region()Juergen Gross
The condition in xen_swiotlb_free_coherent() for deciding whether to call xen_destroy_contiguous_region() is wrong: in case the region to be freed is not contiguous calling xen_destroy_contiguous_region() is the wrong thing to do: it would result in inconsistent mappings of multiple PFNs to the same MFN. This will lead to various strange crashes or data corruption. Instead of calling xen_destroy_contiguous_region() in that case a warning should be issued as that situation should never occur.

2019-07-31drm/msm: Use the correct dma_sync calls in msm_gemRob Clark
[subject was: drm/msm: shake fist angrily at dma-mapping] So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but it falls appart with dma direct ops. The problem is that, depending on display generation, we can have either set of dma ops (mdp4 and dpu have iommu wired to mdss node, which maps to toplevel drm device, but mdp5 has iommu wired up to the mdp sub-node within mdss).

2019-07-31Bluetooth: hci_uart: check for missing tty operationsVladis Dronov
Certain ttys operations (pty_unix98_ops) lack tiocmget() and tiocmset() functions which are called by the certain HCI UART protocols (hci_ath, hci_bcm, hci_intel, hci_mrvl, hci_qca) via hci_uart_set_flow_control() or directly. This leads to an execution at NULL and can be triggered by an unprivileged user. Fix this by adding a helper function and a check for the missing tty operations in the protocols code. This fixes CVE-2019-10207. The Fixes: lines list commits where calls to tiocm[gs]et() or hci_uart_set_flow_control() were added to the HCI UART protocols.

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT. Change the Kconfig dependency of i810 to !CONFIG_PREEMPTION so the driver is not accidentally built on a RT kernel.

2019-07-31nbd: replace kill_bdev() with __invalidate_device() againMunehisa Kamata
Commit abbbdf12497d ("replace kill_bdev() with __invalidate_device()") once did this, but 29eaadc03649 ("nbd: stop using the bdev everywhere") resurrected kill_bdev() and it has been there since then. So buffer_head mappings still get killed on a server disconnection, and we can still hit the BUG_ON on a filesystem on the top of the nbd device. EXT4-fs (nbd0): mounted filesystem with ordered data mode. Opts: (null) block nbd0: Receive control failed (result -32) block nbd0: shutting down sockets print_req_error: I/O error, dev nbd0, sector 66264 flags 3000 EXT4-fs warning (device nbd0): htree_dirblock_to_tree:979: inode #2: lblock 0: comm ls: error -5 reading directory block print_req_error: I/O error, dev nbd0, sector 2264 flags 3000 EXT4-fs error (device nbd0): __ext4_get_inode_loc:4690: inode #2: block 283: comm ls: unable to read itable block EXT4-fs error (device nbd0) in ext4_reserve_inode_write:5894: IO failure ------------[ cut here ]------------ kernel BUG at fs/buffer.c:3057! invalid opcode: 0000 [#1] SMP PTI CPU: 7 PID: 40045 Comm: jbd2/nbd0-8 Not tainted 5.1.0-rc3+ #4 Hardware name: Amazon EC2 m5.12xlarge/, BIOS 1.0 10/16/2017 RIP: 0010:submit_bh_wbc+0x18b/0x190 ...
