2016-10-31ovl: fix get_acl() on tmpfsMiklos Szeredi
tmpfs doesn't have ->get_acl() because it only uses cached acls. This fixes the acl tests in pjdfstest when tmpfs is used as the upper layer of the overlay.

2016-10-31virtio: console: Unlock vqs while freeing buffersMatt Redfearn
Commit c6017e793b93 ("virtio: console: add locks around buffer removal in port unplug path") added locking around the freeing of buffers in the vq. However, when free_buf() is called with can_sleep = true and rproc is enabled, it calls dma_free_coherent() directly, requiring interrupts to be enabled. Currently a WARNING is triggered due to the spin locking around free_buf, with a call stack like this: WARNING: CPU: 3 PID: 121 at ./include/linux/dma-mapping.h:433 free_buf+0x1a8/0x288 Call Trace: [<8040c538>] show_stack+0x74/0xc0 [<80757240>] dump_stack+0xd0/0x110 [<80430d98>] __warn+0xfc/0x130 [<80430ee0>] warn_slowpath_null+0x2c/0x3c [<807e7c6c>] free_buf+0x1a8/0x288 [<807ea590>] remove_port_data+0x50/0xac [<807ea6a0>] unplug_port+0xb4/0x1bc [<807ea858>] virtcons_remove+0xb0/0xfc [<807b6734>] virtio_dev_remove+0x58/0xc0 [<807f918c>] __device_release_driver+0xac/0x134 [<807f924c>] device_release_driver+0x38/0x50 [<807f7edc>] bus_remove_device+0xfc/0x130 [<807f4b74>] device_del+0x17c/0x21c [<807f4c38>] device_unregister+0x24/0x38 [<807b6b50>] unregister_virtio_device+0x28/0x44 Fix this by restructuring the loops to allow the locks to only be taken where it is necessary to protect the vqs, and release it while the buffer is being freed.

2016-10-31ringtest: poll for new buffers once before updating event indexPaolo Bonzini
Updating the event index has a memory barrier and causes more work on the other side to actually signal the event. It is unnecessary if a new buffer has already appeared on the ring, so poll once before doing the update. The effect of this on the 0.9 ring implementation is pretty much invisible, but on the new-style ring it provides a consistent 3% performance improvement.

2016-10-31virtio: update balloon size in balloon "probe"Konstantin Neumoin
The following commit 'fad7b7b27b6a (virtio_balloon: Use a workqueue instead of "vballoon" kthread)' has added a regression. Original code with kthread starts the thread inside probe and checks the necessity to update balloon inside the thread immediately. Nowadays the code behaves differently. Work is queued only on the first command from the host after the negotiation. Thus there is a window especially at the guest startup or the module reloading when the balloon size is not updated until the notification from the host. This patch adds balloon size check at the end of the probe to match original behaviour. Signed-off-by: Konstantin Neumoin <kneumoin@virtuozzo.com> Signed-off-by: Denis V.

2016-10-31virtio_pci: Limit DMA mask to 44 bits for legacy virtio devicesWill Deacon
Legacy virtio defines the virtqueue base using a 32-bit PFN field, with a read-only register indicating a fixed page size of 4k. This can cause problems for DMA allocators that allocate top down from the DMA mask, which is set to 64 bits. In this case, the addresses are silently truncated to 44-bit, leading to IOMMU faults, failure to read from the queue or data corruption. This patch restricts the coherent DMA mask for legacy PCI virtio devices to 44 bits, which matches the specification. Cc: stable@vger.kernel.org Cc: Andy Lutomirski <luto@kernel.org> Cc: Michael S.

2016-10-30aio: fix freeze protection of aio writesJan Kara
Currently we dropped freeze protection of aio writes just after IO was submitted. Thus aio write could be in flight while the filesystem was frozen and that could result in unexpected situation like aio completion wanting to convert extent type on frozen filesystem. Testcase from Dmitry triggering this is like: for ((i=0;i<60;i++));do fsfreeze -f /mnt ;sleep 1;fsfreeze -u /mnt;done & fio --bs=4k --ioengine=libaio --iodepth=128 --size=1g --direct=1 \ --runtime=60 --filename=/mnt/file --name=rand-write --rw=randwrite Fix the problem by dropping freeze protection only once IO is completed in aio_complete().

2016-10-30staging: lustre: ptlrpc: do not sleep if encpool reached max capacitySebastien Buisson
When encryption is enabled RPCs are encrypted just before being sent. The encryption requires allocating memory in the encoding pool. The current implementation in sptlrpc_enc_pool_get_pages() is deadlock-prone. Indeed, if there is no more free pages in the pool, all ptlrpcd threads can end up waiting in a queue, so there is no thread available to process other requests. It means client is not able to process replies from servers that yet contain last committed transno useful to release memory allocated by previous requests, including enc_pool pages. To fix this, in sptlrpc_enc_pool_get_pages(), do not make ptlrpcd threads wait in queue if encoding pool has already reached its maximum capacity. Instead, return -ENOMEM. If functions calling ptl_send_rpc() get -ENOMEM, then put back request in queue by moving it back to RQ_PHASE_NEW phase. As an optimization, do not call ptl_send_rpc() again for requests that already failed to allocate in the enc_pool, as long as there is not enough memory in the enc_pool to satisfy theirs needs. In /sys/fs/lustre/sptlrpc/encrypt_page_pools, add a new 'out of mem' stat to track how many requests fail to allocate memory in the enc_pool.

2016-10-30staging: lustre: obdecho: don't copy lu_siteNiu Yawei
While creating an echo device, echo_device_alloc() copies the lu_site from MD stack, such kind of copy result in uninitialized mutex and other potential issues. Instead of copying the lu_site, we'd use the lu_site by pointer directly.

2016-10-30staging: lustre: ptlrpc: Do not resend req with allow_replaywang di
If the request is allowed to be sent during recovery, and it is not timeout yet, then we do not need to resend it in the final stage of recovery. Unnecessary resend will cause the bulk request to resend the request with different mbit, but same xid, and on the remote server side, it will drop such request with same xid, so it will never get the bulk in this case.

Bring the ability to properly initiate security context on SELinux-enabled client and store it on server side via extended attribute. Security context initialization is not atomic, but that would require a wire protocol change to send security label in the creation request. Filter out security.selinux from xattr cache as it is already cached in system slab.

2016-10-30staging: lustre: ptlrpc: embed highest XID in each requestGregoire Pichon
Atomically assign XIDs and put request and sending list so we can learn the lowest unreplied XID at any point. This allows to embed in every resquests the highest XID for which a reply has been received and does not have an unreplied lower-numbered XID. This will be used by the MDT target to release in-memory reply data corresponding to XIDs of reply received by the client.
