2021-07-27staging: mt7621-pci: avoid to re-disable clock for those pcies not in useSergio Paracuellos1-1/+0
Clock driver for this SoC is using some gates to properly enabling and disabling the access to peripherals. Those gates that are not in use are properly being automatically disabled by the kernel. Pcie driver is explicitly doing a 'clk_disable_unprepare' call for gates of those pcies that are not used. Since kernel has already disabled them, the following warnings appear: WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:952 clk_core_disable+0xe4/0x100 pcie2 already disabled Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.14.0 #0 Stack : 81661680 80082d00 807c0000 00000004 00000000 80a20000 80860000 80792380 814503d4 80862e83 00000000 1431b70 81454360 00000000 00000000 80792380 81431a08 ffffefff fffffea 00000000 81431a14 0000007b 80868820 ffffffff 80792380 1431c70 803d7a24 00000009 807f3a74 00000001 815df810 00000018 0000000 80a20000 ...

2021-07-27staging: rtl8712: error handling refactoringPavel Skripkin2-39/+43
There was strange error handling logic in case of fw load failure. For some reason fw loader callback was doing clean up stuff when fw is not available. I don't see any reason behind doing this. Since this driver doesn't have EEPROM firmware let's just disconnect it in case of fw load failure. Doing clean up stuff in 2 different place which can run concurently is not good idea and syzbot found 2 bugs related to this strange approach. So, in this pacth I deleted all clean up code from fw callback and made a call to device_release_driver() under device_lock(parent) in case of fw load failure. This approach is more generic and it defend driver from UAF bugs, since all clean up code is moved to one place.

2021-07-27staging: rtl8712: get rid of flush_scheduled_workPavel Skripkin5-1/+20
This patch is preparation for following patch for error handling refactoring. flush_scheduled_work() takes (wq_completion)events lock and it can lead to deadlock when r871xu_dev_remove() is called from workqueue. To avoid deadlock sutiation we can change flush_scheduled_work() call to flush_work() call for all possibly scheduled works in this driver, since next patch adds device_release_driver() in case of fw load failure.

The spi_imx->spi_bus_clk may be uninitialized and thus also zero in mx51_ecspi_prepare_message(), which would lead to division by zero in kernel. Since bitbang .setup_transfer callback which initializes the spi_imx->spi_bus_clk is called after bitbang prepare_message callback, iterate over all the transfers in spi_message, find the one with lowest bus frequency, and use that bus frequency for the delay calculation. Note that it is not possible to move this CONFIGREG delay back into the .setup_transfer callback, because that is invoked too late, after the GPIO chipselects were already configured.

2021-07-26drm/amdgpu: Avoid printing of stack contents on firmware load errorJiri Kosina1-4/+3
In case when psp_init_asd_microcode() fails to load ASD microcode file, psp_v12_0_init_microcode() tries to print the firmware filename that failed to load before bailing out. This is wrong because: - the firmware filename it would want it print is an incorrect one as psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading different filenames - it tries to print fw_name, but that's not yet been initialized by that time, so it prints random stack contents, e.g. amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2 amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff" Fix that by bailing out immediately, instead of priting the bogus error message.

This reverts commit 4192f7b5768912ceda82be2f83c87ea7181f9980. It is not true (as stated in the reverted commit changelog) that we never unmap the BAR on failure; it actually does happen properly on amdgpu_driver_load_kms() -> amdgpu_driver_unload_kms() -> amdgpu_device_fini() error path. What's worse, this commit actually completely breaks resource freeing on probe failure (like e.g. failure to load microcode), as amdgpu_driver_unload_kms() notices adev->rmmio being NULL and bails too early, leaving all the resources that'd normally be freed in amdgpu_acpi_fini() and amdgpu_device_fini() still hanging around, leading to all sorts of oopses when someone tries to, for example, access the sysfs and procfs resources which are still around while the driver is gone.

2021-07-26iommu/dma: Fix leak in non-contiguous APIEzequiel Garcia1-0/+1
Currently, iommu_dma_alloc_noncontiguous() allocates a struct dma_sgt_handle object to hold some state needed for iommu_dma_free_noncontiguous(). However, the handle is neither freed nor returned explicitly by the ->alloc_noncontiguous method, and therefore seems leaked. This was found by code inspection, so please review carefully and test. As a side note, it appears the struct dma_sgt_handle type is exposed to users of the DMA-API by linux/dma-map-ops.h, but is has no users or functions returning the type explicitly. This may indicate it's a good idea to move the struct dma_sgt_handle type to drivers/iommu/dma-iommu.c.

Commit 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt in intel_bios.c") moved the workaround for broken or missing VBT to intel_bios.c. However is_port_valid() only protects the handling of different skus of the same display version. Since in intel_setup_outputs() we share the code path with version 9, this would also create port F for SKL/KBL, which does not exist. Missing VBT can be reproduced when starting a headless QEMU with no opregion available.

We were using GRAPHICS_VER() to handle SKL_DFSM register, which means we were not handling GLK correctly since that has GRAPHICS_VER == 9, but DISPLAY_VER == 10. Switch the entire branch to check DISPLAY_VER which makes it more in line with Bspec. Even though the Bspec has an exception for RKL in TGL_DFSM_PIPE_D_DISABLE, we don't have to do anything as the bit has disable semantic and RKL doesn't have pipe D.

2021-07-25octeontx2-pf: Fix interface down flag on errorGeetha sowjanya2-4/+8
In the existing code while changing the number of TX/RX queues using ethtool the PF/VF interface resources are freed and reallocated (otx2_stop and otx2_open is called) if the device is in running state. If any resource allocation fails in otx2_open, driver free already allocated resources and return. But again, when the number of queues changes as the device state still running oxt2_stop is called. In which we try to free already freed resources leading to driver crash. This patch fixes the issue by setting the INTF_DOWN flag on error and free the resources in otx2_stop only if the flag is not set.

2021-07-25octeontx2-af: Fix PKIND overlap between LBK and LMAC interfacesGeetha sowjanya3-4/+11
Currently PKINDs are not assigned to LBK channels. The default value of LBK_CHX_PKIND (channel to PKIND mapping) register is zero, which is resulting in a overlap of pkind between LBK and CGX LMACs. When KPU1 parser config is modified when PTP timestamping is enabled on the CGX LMAC interface it is impacting traffic on LBK interfaces as well. This patch fixes the issue by reserving the PKIND#0 for LBK devices. CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

In case an error occurred in the IRQ handler, the chip status is dumped via devcoredump and all IRQs are disabled, but the chip stays powered for further analysis. The chip is in an undefined state and will not receive any CAN frames, so shut down the timestamping worker, which reads the TBC register regularly, too. This avoids any CRC read error messages if there is a communication problem with the chip.
