The WARN_ONCE macro returns true if the condition is true, not if the warn was raised, so we're printing the scatter list every time it's invalid. This is excessive and makes debugging harder, so this patch prints it just once. Signed-off-by:

A spurious interrupt before the nvme driver has initialized the completion queue may inadvertently cause the driver to believe it has a completion to process. This may result in a NULL dereference since the nvmeq's tags are not set at this point. The patch initializes the host's CQ memory so that a spurious interrupt isn't mistaken for a real completion.

fc transport is treating NVMET_NR_QUEUES as maximum queue count, e.g. admin queue plus NVMET_NR_QUEUES-1 io queues. But NVMET_NR_QUEUES is the number of io queues, so maximum queue count is really NVMET_NR_QUEUES+1. Fix the handling in the target fc transport Signed-off-by:

Sync with NVM Express spec change and FC-NVME 1.18. FC transport sets SGL type to Transport SGL Data Block Descriptor and subtype to transport-specific value 0x0A. Removed the warn-on's on the PRP fields. They are unneeded. They were to check for values from the upper layer that weren't set right, and for the most part were fine. But, with Async events, which reuse the same structure and 2nd time issued the SGL overlay converted them to the Transport SGL values - the warn-on's were errantly firing. Signed-off-by:

When the request is completed, lo_complete_rq() checks cmd->use_aio. However, if this is in fact an aio request, cmd->use_aio will have already been reused as cmd->ref by lo_rw_aio*. Fix it by not using a union. On x86_64, there's a hole after the union anyways, so this doesn't make struct loop_cmd any bigger. Fixes: 92d77332 ("block/loop: fix use after free") Signed-off-by:

The lockdep code had reported the following unsafe locking scenario: CPU0 CPU1 ---- ---- lock(s_active#228); lock(&bdev->bd_mutex/1); lock(s_active#228); lock(&bdev->bd_mutex); *** DEADLOCK *** The deadlock may happen when one task (CPU1) is trying to delete a partition in a block device and another task (CPU0) is accessing tracing sysfs file (e.g. /sys/block/dm-1/trace/act_mask) in that partition. The s_active isn't an actual lock. It is a reference count (kn->count) on the sysfs (kernfs) file. Removal of a sysfs file, however, require a wait until all the references are gone. The reference count is treated like a rwsem using lockdep instrumentation code. The fact that a thread is in the sysfs callback method or in the ioctl call means there is a reference to the opended sysfs or device file. That should prevent the underlying block structure from being removed. Instead of using bd_mutex in the block_device structure, a new blk_trace_mutex is now added to the request_queue structure to protect access to the blk_trace structure. Suggested-by:

Josef Bacik authored
In testing we noticed that nbd would spew if you ran a fio job against the raw device itself. This is because fio calls a block device specific ioctl, however the block layer will first pass this back to the driver ioctl handler in case the driver wants to do something special. Since the device was setup using netlink this caused us to spew every time fio called this ioctl. Since we don't have special handling, just error out for any non-nbd specific ioctl's that come in. This fixes the spew. Signed-off-by:

The code in __brd_direct_access multiplies the pgoff variable by page size and divides it by 512. It can cause overflow on 32-bit architectures. The overflow happens if we create ramdisk larger than 4G and use it as a sparse device. This patch replaces multiplication and division with multiplication by the number of sectors per page.

WARN_ON_ONCE(pi_test_sn(&vmx->pi_desc)) in kvm_vcpu_trigger_posted_interrupt() intends to detect the violation of invariant that VT-d PI notification event is not suppressed when vcpu is in the guest mode. Because the two checks for the target vcpu mode and the target suppress field cannot be performed atomically, the target vcpu mode may change in between. If that does happen, WARN_ON_ONCE() here may raise false alarms. As the previous patch fixed the real invariant breaker, remove this WARN_ON_ONCE() to avoid false alarms, and document the allowed cases instead. Signed-off-by:

Haozhong Zhang authored
In kvm_vcpu_trigger_posted_interrupt() and pi_pre_block(), KVM assumes that PI notification events should not be suppressed when the target vCPU is not blocked. vmx_update_pi_irte() sets the SN field before changing an interrupt from posting to remapping, but it does not check the vCPU mode. Therefore, the change of SN field may break above the assumption. Besides, I don't see reasons to suppress notification events here, so remove the changes of SN field to avoid race condition.

This reverts commit 36ae3c0a. The commit broke compilation on !CONFIG_HAVE_KVM_IRQ_ROUTING. Also, there may be cases with CONFIG_HAVE_KVM_IRQ_ROUTING, where larger gsi values make sense. As the commit was meant as an early indicator to user space that something is wrong, reverting just restores the previous behavior where overly large values are ignored when encountered (without any direct feedback).

With the need to discourage use of less secure dialect, SMB1 (CIFS), we temporarily upgraded the dialect to SMB3 in 4.13, but since there are various servers which only support SMB2.1 (2.1 is more secure than CIFS/SMB1) but not optimal for a default dialect - add support for multidialect negotiation. cifs.ko will now request SMB2.1 or later (ie SMB2.1 or SMB3.0, SMB3.02) and the server will pick the latest most secure one it can support. In addition since we are sending multidialect negotiate, add support for secure negotiate to validate that a man in the middle didn't downgrade us. Signed-off-by:
