Pull rdma fixes from Doug Ledford: "A small collection of -rc fixes. Mostly. One API addition, but that's because we wanted to use it in a fix. There's also a bug fix that is going to render the 5.5 kernel's soft-RoCE driver incompatible with all soft-RoCE versions prior, but it's required to actually implement the protocol according to the RoCE spec and required in order for the soft-RoCE driver to be able to successfully work with actual RoCE hardware. Summary: - Update Steve Wise info - Fix for soft-RoCE crc calculations (will break back compatibility, but only with the soft-RoCE driver, which has had this bug since it was introduced and it is an on-the-wire bug, but will make soft-RoCE fully compatible with real RoCE hardware) - cma init fixup - counters oops fix - fix for mlx4 init/teardown sequence - fix for mkx5 steering rules - introduce a cleanup API, which isn't a fix, but we want to use it in the next fix - fix for mlx5 memory management that uses API in previous patch" * tag 'for-linus' of git:// IB/mlx5: Fix device memory flows IB/core: Introduce rdma_user_mmap_entry_insert_range() API IB/mlx5: Fix steering rule of drop and count IB/mlx4: Follow mirror sequence of device add during device removal RDMA/counter: Prevent auto-binding a QP which are not tracked with res rxe: correctly calculate iCRC for unaligned payloads Update mailmap info for Steve Wise RDMA/cma: add missed unregister_pernet_subsys in init failure

2019-12-15Merge branch 'remove-ksys-mount-dup' of ↵Linus Torvalds-41/+63
git:// Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski: "This small series replaces all in-kernel calls to the userspace-focused ksys_mount() and ksys_dup() with calls to kernel-centric functions: For each replacement of ksys_mount() with do_mount(), one needs to verify that the first and third parameter (char *dev_name, char *type) are strings allocated in kernelspace and that the fifth parameter (void *data) is either NULL or refers to a full page (only occurence in init/do_mounts.c::do_mount_root()). The second and fourth parameters (char *dir_name, unsigned long flags) are passed by ksys_mount() to do_mount() unchanged, and therefore do not require particular care. Moreover, instead of pretending to be userspace, the opening of /dev/console as stdin/stdout/stderr can be implemented using in-kernel functions as well. Thereby, ksys_dup() can be removed for good" [ This doesn't get rid of the special "kernel init runs with KERNEL_DS" case, but it at least removes _some_ of the users of "treat kernel pointers as user pointers for our magical init sequence". One day we'll hopefully be rid of it all, and can initialize our init_thread addr_limit to USER_DS. - Linus ] * 'remove-ksys-mount-dup' of git:// fs: remove ksys_dup() init: unify opening /dev/console as stdin/stdout/stderr init: use do_mount() instead of ksys_mount() initrd: use do_mount() instead of ksys_mount() devtmpfs: use do_mount() instead of ksys_mount()

2019-12-13xen-blkback: prevent premature module unloadPaul Durrant-0/+10
Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem cache. This cache is destoyed when xen-blkif is unloaded so it is necessary to wait for the deferred free routine used for such objects to complete. This necessity was missed in commit 14855954f636 "xen-blkback: allow module to be cleanly unloaded". This patch fixes the problem by taking/releasing extra module references in xen_blkif_alloc/free() respectively.

2019-12-13CIFS: Close cached root handle only if it has a leasePavel Shilovsky-4/+25
SMB2_tdis() checks if a root handle is valid in order to decide whether it needs to close the handle or not. However if another thread has reference for the handle, it may end up with putting the reference twice. The extra reference that we want to put during the tree disconnect is the reference that has a directory lease. So, track the fact that we have a directory lease and close the handle only in that case. Signed-off-by: Pavel Shilovsky <> Reviewed-by: Ronnie Sahlberg <> Signed-off-by: Steve French <>

2019-12-12of/platform: Unconditionally pause/resume sync state during kernel initSaravana Kannan-3/+3
Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init and of_platform_populate()") paused/resumed sync state during init only if Linux had parsed and populated a devicetree. However, the check for that (of_have_populated_dt()) can change after of_platform_default_populate_init() executes. One example of this is when devicetree unittests are enabled. This causes an unmatched pause/resume of sync state. To avoid this, just unconditionally pause/resume sync state during init.

2019-12-12IB/mlx5: Fix device memory flowsYishai Hadas-52/+105
Fix device memory flows so that only once there will be no live mmaped VA to a given allocation the matching object will be destroyed. This prevents a potential scenario that existing VA that was mmaped by one process might still be used post its deallocation despite that it's owned now by other process. The above is achieved by integrating with IB core APIs to manage mmap/munmap. Only once the refcount will become 0 the DM object and its underlay area will be freed.

2019-12-12PCI: rockchip: Fix IO outbound ATU register numberEnric Balletbo i Serra-1/+3
Since 62240a88004b ("PCI: rockchip: Drop storing driver private outbound resource data), the offset calculation is wrong to access the register number to program the IO outbound ATU. Fix this by computing the ATU IO register number based on the number of MEM registers, not the size of the IO region. This causes 'synchronous external aborts' like the following: mwifiex_pcie 0000:01:00.0: enabling device (0000 -> 0002) mwifiex_pcie: PCI memory map Virt0: 00000000a573ad00 PCI memory map Virt2: 00000000783126c4 Internal error: synchronous external abort: 96000210 [#1] PREEMPT SMP Modules linked in: mwifiex_pcie(+) mwifiex uvcvideo cfg80211 atmel_mxt_ts videobuf2_vmalloc ...
