2021-01-07iommu/vt-d: Move intel_iommu info from struct intel_svm to struct intel_svm_devLiu Yi L
'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.

2021-01-06dm snapshot: flush merged data before committing metadataAkilesh Kailash
If the origin device has a volatile write-back cache and the following events occur: 1: After finishing merge operation of one set of exceptions, merge_callback() is invoked. 2: Update the metadata in COW device tracking the merge completion. This update to COW device is flushed cleanly. 3: System crashes and the origin device's cache where the recent merge was completed has not been flushed. During the next cycle when we read the metadata from the COW device, we will skip reading those metadata whose merge was completed in step (1). This will lead to data loss/corruption. To address this, flush the origin device post merge IO before updating the metadata.

2021-01-06bpftool: Fix compilation failure for net.o with older glibcAlan Maguire
For older glibc ~2.17, #include'ing both linux/if.h and net/if.h fails due to complaints about redefinition of interface flags: CC net.o In file included from net.c:13:0: /usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’ IFF_UP = 1<<0, /* sysfs */ ^ /usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here IFF_UP = 0x1, /* Interface is up. */ The issue was fixed in kernel headers in [1], but since compilation of net.c picks up system headers the problem can recur. Dropping #include <linux/if.h> resolves the issue and it is not needed for compilation anyhow.

2021-01-06Revert "drm/amd/display: Fix memory leaks in S3 resume"Alex Deucher
This reverts commit a135a1b4c4db1f3b8cbed9676a40ede39feb3362. This leads to blank screens on some boards after replugging a display. Revert until we understand the root cause and can fix both the leak and the blank screen after replug.

2021-01-06drm/amdgpu/display: drop DCN support for aarch64Alex Deucher
From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.

2021-01-06drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCOXiaojian Du
This patch is to improve the fine grain tuning function for RV/RV2/PCO. The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage to config gfxclk. Meanwhile, another sysfs node -- power_dpm_force_perfomance_level also affects the gfx clk. It will cause confusion when these two sysfs nodes works together. So this patch adds one flag to avoid this confusion, the flag will make these two sysfs nodes work separately. The flag is set as "disabled" by default, so the fine grain tuning function will be disabled by default. Only when power_dpm_force_perfomance_level is changed to "manual" mode, the flag will be set as "enabled", and the fine grain tuning function will be enabled. In other profile modes, including "auto", "high", "low", "profile_peak", "profile_standard", "profile_min_sclk", "profile_min_mclk", the flag will be set as "disabled", and the od range of fine grain tuning function will be restored default value.
