[ Upstream commit 2cd4bd19 ] Protection key tracking information is not copied over to the mm_struct of the child during fork(). This can cause the child to erroneously allocate keys that were already allocated. Any allocated execute-only key is lost aswell. Add code; called by dup_mmap(), to copy the pkey state from parent to child explicitly. This problem was originally found by Dave Hansen on x86, which turns out to be a problem on powerpc aswell.

[ Upstream commit de93b40d ] For SAS3 and later controllers, FW sets the reset adapter bit indicating the driver to perform a controller reset. Driver needs to check if this bit is set before doing a reset. This reduces the driver probe failure time to 180seconds in case there is a faulty controller connected. Signed-off-by:

The reason this case is valid is due to find_lock_delalloc_range returning any available range after the passed delalloc_start and ignoring whether the page under writeback is within that range. In turn ordered extents (OE) are always created for the returned range from find_lock_delalloc_range. If, however, a failure occurs while OE are being created then the clean up code in btrfs_cleanup_ordered_extents will be called. Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider the case of such 'foreign' range being processed and instead it always assumes that the range OE are created for belongs to the page. This leads to the first page of such foregin range to not be cleaned up since it's deliberately missed and skipped by the current cleaning up code. Fix this by correctly checking whether the current page belongs to the range being instantiated and if so adjsut the range parameters passed for cleaning up. If it doesn't, then just clean the whole OE range directly. Fixes: 52427260 ("btrfs: Handle delalloc error correctly to avoid ordered extent hang") CC: stable@vger.kernel.org # 4.14+ Reviewed-by:

[ Upstream commit 5eaad97a ] This callback is called only from writepage_delalloc which in turn is guaranteed to be called from the data page writeout path. In the end there is no reason to have the call to this function to be indrected via the extent_io_ops structure. This patch removes the callback definition, exports the function and calls it directly. No functional changes. Reviewed-by:

[ Upstream commit a5fb1142 ] When a transaction commit starts, it attempts to pause scrub and it blocks until the scrub is paused. So while the transaction is blocked waiting for scrub to pause, we can not do memory allocation with GFP_KERNEL from scrub, otherwise we risk getting into a deadlock with reclaim. Checking for scrub pause requests is done early at the beginning of the while loop of scrub_stripe() and later in the loop, scrub_extent() and scrub_raid56_parity() are called, which in turn call scrub_pages() and scrub_pages_for_parity() respectively. These last two functions do memory allocations using GFP_KERNEL. Same problem could happen while scrubbing the super blocks, since it calls scrub_pages(). We also can not have any of the worker tasks, created by the scrub task, doing GFP_KERNEL allocations, because before pausing, the scrub task waits for all the worker tasks to complete (also done at scrub_stripe()). So make sure GFP_NOFS is used for the memory allocations because at any time a scrub pause request can happen from another task that started to commit a transaction.

[ Upstream commit 234ff0b7 ] Testing has revealed an occasional crash which appears to be caused by a race between kvmppc_switch_mmu_to_hpt and kvm_unmap_hva_range_hv. The symptom is a NULL pointer dereference in __find_linux_pte() called from kvm_unmap_radix() with kvm->arch.pgtable == NULL. Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear kvm->arch.pgtable (via kvmppc_free_radix()) before setting kvm->arch.radix to NULL, and there is nothing to prevent kvm_unmap_hva_range_hv() or the other MMU callback functions from being called concurrently with kvmppc_switch_mmu_to_hpt() or kvmppc_switch_mmu_to_radix(). This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock around the assignments to kvm->arch.radix, and makes sure that the partition-scoped radix tree or HPT is only freed after changing kvm->arch.radix. This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure that the clearing of each rmap array (one per memslot) doesn't happen concurrently with use of the array in the kvm_unmap_hva_range_hv() or the other MMU callbacks.

[ Upstream commit 104f708f ] Until the vfio-ap driver came into live there was a well known agreement about the way how ap devices are initialized and their states when the driver's probe function is called. However, the vfio device driver when receiving an ap queue device does additional resets thereby removing the registration for interrupts for the ap device done by the ap bus core code. So when later the vfio driver releases the device and one of the default zcrypt drivers takes care of the device the interrupt registration needs to get renewed. The current code does no renew and result is that requests send into such a queue will never see a reply processed - the application hangs. This patch adds a function which resets the aq queue state machine for the ap queue device and triggers the walk through the initial states (which are reset and registration for interrupts). This function is now called before the driver's probe function is invoked. When the association between driver and device is released, the driver's remove function is called. The current implementation calls a ap queue function ap_queue_remove(). This invokation has been moved to the ap bus function to make the probe / remove pair for ap bus and drivers more symmetric.

[ Upstream commit e670de54 ] In kvp_send_key(), we do need call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO, because it turns out the userland hv_kvp_daemon needs the info of operation, adapter_id and addr_family. With the incorrect fc62c3b1, the host can't get the VM's IP via KVP. And, fc62c3b1 added a "break;", but actually forgot to initialize the key_size/value in the case of KVP_OP_SET, so the default key_size of 0 is passed to the kvp daemon, and the pool files /var/lib/hyperv/.kvp_pool_* can't be updated. This patch effectively rolls back the previous fc62c3b1, and correctly fixes the "this statement may fall through" warnings. This patch is tested on WS 2012 R2 and 2016.

[ Upstream commit a9f9ca33 ] Currently, i915 appears to rely on blocking modesets on no-longer-present MSTB ports by simply returning NULL for ->best_encoder(), which in turn causes any new atomic commits that don't disable the CRTC to fail. This is wrong however, since we still want to allow userspace to disable CRTCs on no-longer-present MSTB ports by changing the DPMS state to off and this still requires that we retrieve an encoder. So, fix this by always returning a valid encoder regardless of the state of the MST port.

This fix does not impact 64bit system because on 64bit max_low_pfn is the same as max_pfn. Signed-off-by:

[ Upstream commit fc62c3b1 ] We don't need to call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO in kvp_send_key(), because here we just need to pass on the op code from the host to the userspace; when the userspace returns the info requested by the host, we pass the info on to the host in kvp_respond_to_host() -> process_ob_ipinfo(). BTW, the current buggy code actually doesn't cause any harm, because only message->kvp_hdr.operation is used by the userspace, in the case of KVP_OP_GET_IP_INFO. The patch also adds a missing "break;" in kvp_send_key(). BTW, the current buggy code actually doesn't cause any harm, because in the case of KVP_OP_SET, the unexpected fall-through corrupts message->body.kvp_set.data.key_size, but that is not really used: see the definition of struct hv_kvp_exchg_msg_value.

[ Upstream commit 2ecefa0a ] The keyctl_dh_params struct in uapi/linux/keyctl.h contains the symbol "private" which means that the header file will cause compilation failure if #included in to a C++ program. Further, the patch that added the same struct to the keyutils package named the symbol "priv", not "private". The previous attempt to fix this (commit 8a2336e5) did so by simply renaming the kernel's copy of the field to dh_private, but this then breaks existing userspace and as such has been reverted (commit 8c0f9f5b). [And note, to those who think that wrapping the struct in extern "C" {} will work: it won't; that only changes how symbol names are presented to the assembler and linker.]. Instead, insert an anonymous union around the "private" member and add a second member in there with the name "priv" to match the one in the keyutils package. The "private" member is then wrapped in !__cplusplus cpp-conditionals to hide it from C++.
