2020-07-24scsi: firmware: qcom_scm: Add support for programming inline crypto keysEric Biggers
Add support for the Inline Crypto Engine (ICE) key programming interface that's needed for the ufs-qcom driver to use inline encryption on Snapdragon SoCs. This interface consists of two SCM calls: one to program a key into a keyslot, and one to invalidate a keyslot. Although the UFS specification defines a standard way to do this, on these SoCs the Linux kernel isn't permitted to access the needed crypto configuration registers directly; these SCM calls must be used instead.

2020-07-24xen-netfront: fix potential deadlock in xennet_remove()Andrea Righi
There's a potential race in xennet_remove(); this is what the driver is doing upon unregistering a network device: 1. state = read bus state 2. if state is not "Closed": 3. request to set state to "Closing" 4. wait for state to be set to "Closing" 5. request to set state to "Closed" 6. wait for state to be set to "Closed" If the state changes to "Closed" immediately after step 1 we are stuck forever in step 4, because the state will never go back from "Closed" to "Closing". Make sure to check also for state == "Closed" in step 4 to prevent the deadlock. Also add a 5 sec timeout any time we wait for the bus state to change, to avoid getting stuck forever in wait_event().

2020-07-24RDMA/mlx5: Add missing srcu_read_lock in ODP implicit flowMaor Gottlieb
According to the locking scheme, mlx5_ib_update_xlt() should be called with srcu_read_lock(dev->odp->srcu). Prefetch missed this. This fixes the below WARN from lockdep_assert_held(): WARNING: CPU: 1 PID: 1130 at drivers/infiniband/hw/mlx5/odp.c:132 mlx5_odp_populate_xlt+0x175/0x180 [mlx5_ib] Modules linked in: xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xt_addrtype iptable_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 br_netfilter overlay ib_srp scsi_transport_srp rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi rdma_cm iw_cm ib_umad ib_ipoib ib_cm mlx5_ib ib_uverbs ib_core mlx5_core mlxfw ptp pps_core CPU: 1 PID: 1130 Comm: kworker/u16:11 Tainted: G W 5.8.0-rc5_for_upstream_debug_2020_07_13_11_04 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.1-0-ga5cab58e9a3f-prebuilt.qemu.org 04/01/2014 Workqueue: events_unbound mlx5_ib_prefetch_mr_work [mlx5_ib] RIP: 0010:mlx5_odp_populate_xlt+0x175/0x180 [mlx5_ib] Code: 08 e2 85 c0 0f 84 65 ff ff ff 49 8b 87 60 01 00 00 be ff ff ff ff 48 8d b8 b0 39 00 00 e8 93 e0 50 e1 85 c0 0f 85 45 ff ff ff <0f> 0b e9 3e ff ff ff 0f 0b eb c7 0f 1f 44 00 00 48 8b 87 98 0f 00 RSP: 0018:ffff88840f44fc68 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff88840cc9d000 RCX: ffff88840efcd940 RDX: 0000000000000000 RSI: ffff88844871b9b0 RDI: ffff88840efce100 RBP: ffff88840cc9d040 R08: 0000000000000040 R09: 0000000000000001 R10: ffff88846ced3068 R11: 0000000000000000 R12: 00000000000156ec R13: 0000000000000004 R14: 0000000000000004 R15: ffff888439941000 FS: 0000000000000000(0000) GS:ffff88846fa80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f8536d12430 CR3: 0000000437a5e006 CR4: 0000000000360ea0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: mlx5_ib_update_xlt+0x37c/0x7c0 [mlx5_ib] pagefault_mr+0x315/0x440 [mlx5_ib] mlx5_ib_prefetch_mr_work+0x56/0xa0 [mlx5_ib] process_one_work+0x215/0x5c0 worker_thread+0x3c/0x380 ? process_one_work+0x5c0/0x5c0 kthread+0x133/0x150 ? kthread_park+0x90/0x90 ret_from_fork+0x1f/0x30 Hold the SRCU during prefetch, even though it strictly isn't needed since prefetch is holding the num_deferred_work it does make it easier to reason about.

2020-07-24RDMA/core: Update write interface to use automatic object lifetimeLeon Romanovsky
The automatic object lifetime model allows us to change the write() interface to have the same logic as the ioctl() path. Update the create/alloc functions to be in the following format, so the code flow will be the same: * Allocate objects * Initialize them * Call to the drivers, this is last step that is allowed to fail * Finalize object * Return response and allow to core code to handle abort/commit respectively.

2020-07-24driver core: Change delimiter in devlink device's name to "--"Saravana Kannan
The devlink device name is of the form "supplier:consumer". But ":" is fairly common in device names and makes it visually hard to distinguish supplier and consumer. So, replace it with "--" to make it easier.

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/drivers Memory controller drivers for v5.9 The drivers/memory directory with memory controller drivers, over the last days grew in numbers but lacked any coordinated care. The generic part (device tree helpers) were pulled in through various trees, depending on driver needs. The patchset is a first try to improve code quality of memory controller drivers. Mostly these are non-intrusive fixes for GCC, checkpatch or sparse warnings. This also fixes missing SPDX tags or improves generic code quality (whitespace, const correctness). Last commit appoints also Krzysztof Kozlowski as a maintainer. * tag 'memory-controller-drv-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (22 commits) MAINTAINERS: Add Krzysztof Kozlowski as maintainer of memory controllers memory: samsung: exynos-srom: Describe the Kconfig entry memory: Describe the MEMORY Kconfig entry memory: da8xx-ddrctl: Remove unused 'node' variable memory: fsl_ifc: Fix whitespace issues memory: pl172: Add GPLv2 SPDX license header memory: omap-gpmc: Fix whitespace issue memory: omap-gpmc: Include <linux/sizes.h> for SZ_16M memory: mtk-smi: Add argument to function pointer definition memory: brcmstb_dpfe: Remove unneeded braces memory: brcmstb_dpfe: Constify the contents of string memory: ti-emif-pm: Fix cast to iomem pointer memory: ti-aemif: Rename SS to SSTROBE to avoid name conflicts memory: emif: Silence platform_get_irq() error in driver memory: emif: Fix whitespace coding style violations memory: emif: Put constant in comparison on the right side memory: emif-asm-offsets: Add GPLv2 SPDX license header memory: of: Remove unneeded extern from function declarations memory: of: Correct indentation memory: of: Remove __func__ in device related messages ...

2020-07-24RDMA/mlx5: Allow SQ modificationMaor Gottlieb
Currently the SQ is set to a ready state when the RAW QP is modified to INIT. When the TIS is modified, e.g. to change the lag_tx_affinity, then SQs which are already in the ready state will not be affected. Open a window to modify the SQ behavior by setting the SQ as ready only when QP was modified to RTS.

Sometimes we abort the reset procedure and in that case we can't leave device CPU in halt mode. - set each CQ to its own work queue to prevent a race between completions on different CQs. - Use queue pi/ci in order to determine queue occupancy. This is done to make the code reusable between current and future ASICs. - Add more validations for user inputs. - Refactor PCIe controller configuration to make the code reusable between current and future ASICs. - Update firmware interface headers to latest version - Move all common code to a dedicated common sub-folder * tag 'misc-habanalabs-next-2020-07-24' of git://people.freedesktop.org/~gabbayo/linux: (28 commits) habanalabs: Fix memory leak in error flow of context initialization habanalabs: use no flags on MMU cache invalidation habanalabs: enable device before hw_init() habanalabs: create internal CB pool habanalabs: update hl_boot_if.h from firmware habanalabs: create common folder habanalabs: check for DMA errors when clearing memory habanalabs: verify queue can contain all cs jobs habanalabs: Assign each CQ with its own work queue habanalabs: halt device CPU only upon certain reset habanalabs: remove unused hash habanalabs: use queue pi/ci in order to determine queue occupancy habanalabs: configure maximum queues per asic habanalabs: remove soft-reset support from GAUDI habanalabs: PCIe iATU refactoring habanalabs: Extract ECC information from FW habanalabs: Add dropped cs statistics info struct habanalabs: extract cpu boot status lookup habanalabs: rephrase error messages habanalabs: Increase queues depth ...
