2021-01-07btrfs: print the actual offset in btrfs_root_nameJosef Bacik
We're supposed to print the root_key.offset in btrfs_root_name in the case of a reloc root, not the objectid. Fix this helper to take the key so we have access to the offset when we need it.

2021-01-07io_uring: synchronise ev_posted() with waitqueuesPavel Begunkov
waitqueue_active() needs smp_mb() to be in sync with waitqueues modification, but we miss it in io_cqring_ev_posted*() apart from cq_wait() case. Take an smb_mb() out of wq_has_sleeper() making it waitqueue_active(), and place it a few lines before, so it can synchronise other waitqueue_active() as well. The patch doesn't add any additional overhead, so even if there are no problems currently, it's just safer to have it this way.

2021-01-07io_uring: trigger eventfd for IOPOLLPavel Begunkov
Make sure io_iopoll_complete() tries to wake up eventfd, which currently is skipped together with io_cqring_ev_posted() for non-SQPOLL IOPOLL. Add an iopoll version of io_cqring_ev_posted(), duplicates a bit of code, but they actually use different sets of wait queues may be for better.

iommu_flush_dev_iotlb() is called to invalidate caches on a device but only loops over the devices which are fully-attached to the domain.

'struct intel_svm' is shared by all devices bound to a give process, but records only a single pointer to a 'struct intel_iommu'. Consequently, cache invalidations may only be applied to a single DMAR unit, and are erroneously skipped for the other devices. In preparation for fixing this, rework the structures so that the iommu pointer resides in 'struct intel_svm_dev', allowing 'struct intel_svm' to track them in its device list.

2021-01-07iommu/arm-smmu-qcom: Initialize SCTLR of the bypass contextBjorn Andersson
On SM8150 it's occasionally observed that the boot hangs in between the writing of SMEs and context banks in arm_smmu_device_reset(). The problem seems to coincide with a display refresh happening after updating the stream mapping, but before clearing - and there by disabling translation - the context bank picked to emulate translation bypass. Resolve this by explicitly disabling the bypass context already in cfg_probe.

2021-01-07dmabuf: fix use-after-free of dmabuf's file->f_inodeCharan Teja Reddy
It is observed 'use-after-free' on the dmabuf's file->f_inode with the race between closing the dmabuf file and reading the dmabuf's debug info. Consider the below scenario where P1 is closing the dma_buf file and P2 is reading the dma_buf's debug info in the system: P1 P2 dma_buf_debug_show() dma_buf_put() __fput() file->f_op->release() dput() .... dentry_unlink_inode() iput(dentry->d_inode) (where the inode is freed) mutex_lock(&db_list.lock) read 'dma_buf->file->f_inode' (the same inode is freed by P1) mutex_unlock(&db_list.lock) dentry->d_op->d_release()--> dma_buf_release() ..... mutex_lock(&db_list.lock) removes the dmabuf from the list mutex_unlock(&db_list.lock) In the above scenario, when dma_buf_put() is called on a dma_buf, it first frees the dma_buf's file->f_inode(=dentry->d_inode) and then removes this dma_buf from the system db_list. In between P2 traversing the db_list tries to access this dma_buf's file->f_inode that was freed by P1 which is a use-after-free case. Since, __fput() calls f_op->release first and then later calls the d_op->d_release, move the dma_buf's db_list removal from d_release() to f_op->release(). This ensures that dma_buf's file->f_inode is not accessed after it is released.

pointer in HW, then in driver The previous patch fixes a TEF vs. TX race condition, by first updating the TEF tail pointer in hardware, and then updating the driver internal pointer. The same pattern exists in the RX-path, too. This should be no problem, as the driver accesses the RX-FIFO from the interrupt handler only, thus the access is properly serialized. Fix the order here, too, so that the TEF- and RX-path look similar.

2021-01-07can: mcp251xfd: mcp251xfd_handle_tefif(): fix TEF vs. TX race conditionMarc Kleine-Budde
The mcp251xfd driver uses a TX FIFO for sending CAN frames and a TX Event FIFO (TEF) for completed TX-requests. The TEF event handling in the mcp251xfd_handle_tefif() function has a race condition. It first increments the tx-ring's tail counter to signal that there's room in the TX and TEF FIFO, then it increments the TEF FIFO in hardware. A running mcp251xfd_start_xmit() on a different CPU might not stop the txqueue (as the tx-ring still shows free space). The next mcp251xfd_start_xmit() will push a message into the chip and the TX complete event might overflow the TEF FIFO. This patch changes the order to fix the problem.

According to the TCAN4550 datasheet "SLLSF91 - DECEMBER 2018" the tcan4x5x has the same bittiming constants as a m_can revision 3.2.x/3.3.0. The tcan4x5x chip I'm using identifies itself as m_can revision 3.2.1, so remove the tcan4x5x specific bittiming values and rely on the values in the m_can driver, which are selected according to core revision.

In m_can_class_register() the clock is started, but stopped on exit. When calling m_can_class_unregister(), the clock is stopped a second time. This patch removes the erroneous m_can_clk_stop() in m_can_class_unregister().

2021-01-06sh: dma: fix kconfig dependency for G2_DMANecip Fazil Yildiran
When G2_DMA is enabled and SH_DMA is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for SH_DMA_API Depends on [n]: SH_DMA [=n] Selected by [y]: - G2_DMA [=y] && SH_DREAMCAST [=y] The reason is that G2_DMA selects SH_DMA_API without depending on or selecting SH_DMA while SH_DMA_API depends on SH_DMA. When G2_DMA was first introduced with commit 40f49e7ed77f ("sh: dma: Make G2 DMA configurable."), this wasn't an issue since SH_DMA_API didn't have such dependency, and this way was the only way to enable it since SH_DMA_API was non-visible. However, later SH_DMA_API was made visible and dependent on SH_DMA with commit d8902adcc1a9 ("dmaengine: sh: Add Support SuperH DMA Engine driver"). Let G2_DMA depend on SH_DMA_API instead to avoid Kbuild issues.
