2018-10-18r8169: fix NAPI handling under high loadHeiner Kallweit
rtl_rx() and rtl_tx() are called only if the respective bits are set in the interrupt status register. Under high load NAPI may not be able to process all data (work_done == budget) and it will schedule subsequent calls to the poll callback. rtl_ack_events() however resets the bits in the interrupt status register, therefore subsequent calls to rtl8169_poll() won't call rtl_rx() and rtl_tx() - chip interrupts are still disabled. Fix this by calling rtl_rx() and rtl_tx() independent of the bits set in the interrupt status register. Both functions will detect if there's nothing to do for them.

2018-10-18drm: Get ref on CRTC commit object when waiting for flip_doneLeo Li
This fixes a general protection fault, caused by accessing the contents of a flip_done completion object that has already been freed. It occurs due to the preemption of a non-blocking commit worker thread W by another commit thread X. X continues to clear its atomic state at the end, destroying the CRTC commit object that W still needs. Switching back to W and accessing the commit objects then leads to bad results. Worker W becomes preemptable when waiting for flip_done to complete. At this point, a frequently occurring commit thread X can take over. Here's an example where W is a worker thread that flips on both CRTCs, and X does a legacy cursor update on both CRTCs: ... 1. W does flip work 2. W runs commit_hw_done() 3. W waits for flip_done on CRTC 1 4. > flip_done for CRTC 1 completes 5. W finishes waiting for CRTC 1 6. W waits for flip_done on CRTC 2 7. > Preempted by X 8. > flip_done for CRTC 2 completes 9. X atomic_check: hw_done and flip_done are complete on all CRTCs 10. X updates cursor on both CRTCs 11. X destroys atomic state 12. X done 13. > Switch back to W 14. W waits for flip_done on CRTC 2 15. W raises general protection fault The error looks like so: general protection fault: 0000 [#1] PREEMPT SMP PTI **snip** Call Trace: lock_acquire+0xa2/0x1b0 _raw_spin_lock_irq+0x39/0x70 wait_for_completion_timeout+0x31/0x130 drm_atomic_helper_wait_for_flip_done+0x64/0x90 [drm_kms_helper] amdgpu_dm_atomic_commit_tail+0xcae/0xdd0 [amdgpu] commit_tail+0x3d/0x70 [drm_kms_helper] process_one_work+0x212/0x650 worker_thread+0x49/0x420 kthread+0xfb/0x130 ret_from_fork+0x3a/0x50 Modules linked in: x86_pkg_temp_thermal amdgpu(O) chash(O) gpu_sched(O) drm_kms_helper(O) syscopyarea sysfillrect sysimgblt fb_sys_fops ttm(O) drm(O) Note that i915 has this issue masked, since hw_done is signaled after waiting for flip_done. Doing so will block the cursor update from happening until hw_done is signaled, preventing the cursor commit from destroying the state. v2: The reference on the commit object needs to be obtained before hw_done() is signaled, since that's the point where another commit is allowed to modify the state. Assuming that the new_crtc_state->commit object still exists within flip_done() is incorrect. Fix by getting a reference in setup_commit(), and releasing it during default_clear().

2018-10-17virtio_net: avoid using netif_tx_disable() for serializing tx routineAke Koomsin
Commit 713a98d90c5e ("virtio-net: serialize tx routine during reset") introduces netif_tx_disable() after netif_device_detach() in order to avoid use-after-free of tx queues. However, there are two issues. 1) Its operation is redundant with netif_device_detach() in case the interface is running. 2) In case of the interface is not running before suspending and resuming, the tx does not get resumed by netif_device_attach(). This results in losing network connectivity. It is better to use netif_tx_lock_bh()/netif_tx_unlock_bh() instead for serializing tx routine during reset. This also preserves the symmetry of netif_device_detach() and netif_device_attach().

2018-10-17mlxsw: core: Fix use-after-free when flashing firmware during initIdo Schimmel
When the switch driver (e.g., mlxsw_spectrum) determines it needs to flash a new firmware version it resets the ASIC after the flashing process. The bus driver (e.g., mlxsw_pci) then registers itself again with mlxsw_core which means (among other things) that the device registers itself again with the hwmon subsystem again. Since the device was registered with the hwmon subsystem using devm_hwmon_device_register_with_groups(), then the old hwmon device (registered before the flashing) was never unregistered and was referencing stale data, resulting in a use-after free. Fix by removing reliance on device managed APIs in mlxsw_hwmon_init().

2018-10-17net: qla3xxx: Remove overflowing shift statementNathan Chancellor
Clang currently warns: drivers/net/ethernet/qlogic/qla3xxx.c:384:24: warning: signed shift result (0xF00000000) requires 37 bits to represent, but 'int' only has 32 bits [-Wshift-overflow] ((ISP_NVRAM_MASK << 16) | qdev->eeprom_cmd_data)); ~~~~~~~~~~~~~~ ^ ~~ 1 warning generated. The warning is certainly accurate since ISP_NVRAM_MASK is defined as (0x000F << 16) which is then shifted by 16, resulting in 64424509440, well above UINT_MAX. Given that this is the only location in this driver where ISP_NVRAM_MASK is shifted again, it seems likely that ISP_NVRAM_MASK was originally defined without a shift and during the move of the shift to the definition, this statement wasn't properly removed (since ISP_NVRAM_MASK is used in the statenent right above this). Only the maintainers can confirm this since this statment has been here since the driver was first added to the kernel.

Commit 7a68d9fb8510 ("USB: usbdevfs: sanitize flags more") checks the transfer flags for URBs submitted from userspace via usbfs. However, the check for whether the USBDEVFS_URB_SHORT_NOT_OK flag should be allowed for a control transfer was added in the wrong place, before the code has properly determined the direction of the control transfer. (Control transfers are special because for them, the direction is set by the bRequestType byte of the Setup packet rather than direction bit of the endpoint address.) This patch moves code which sets up the allow_short flag for control transfers down after is_in has been set to the correct value.

Previously we only allowed a single header key per pedit action to change the header. This used to result in the last header key in the pedit action to overwrite previous headers. We now keep track of them and allow multiple header keys per pedit action.

Previously we did not correctly change headers when using multiple pedit actions with partial masks. We now take this into account and no longer just commit the last pedit action.

2018-10-15net: fec: don't dump RX FIFO register when not availableFugang Duan
Commit db65f35f50e0 ("net: fec: add support of ethtool get_regs") introduce ethool "--register-dump" interface to dump all FEC registers. But not all silicon implementations of the Freescale FEC hardware module have the FRBR (FIFO Receive Bound Register) and FRSR (FIFO Receive Start Register) register, so we should not be trying to dump them on those that don't. To fix it we create a quirk flag, FEC_QUIRK_HAS_RFREG, and check it before dump those RX FIFO registers. Signed-off-by: Fugang Duan <fugang.duan@nxp.com> Signed-off-by: David S.

On GENETv5, there is a hardware issue which prevents the GENET hardware from generating a link UP interrupt when the link is operating at 10Mbits/sec. Since we do not have any way to configure the link detection logic, fallback to polling in that case.

2018-10-15r8169: Enable MSI-X on RTL8106eJian-Hong Pan
Originally, we have an issue where r8169 MSI-X interrupt is broken after S3 suspend/resume on RTL8106e of ASUS X441UAR. 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller [10ec:8136] (rev 07) Subsystem: ASUSTeK Computer Inc.

That breaks the MSI-X interrupt. Therefore, we can only fall back to MSI interrupt to fix the issue at that time. However, there is a commit which resolves the drivers getting nothing in PCI BAR=4 after system resumes. It is 04cb3ae895d7 "PCI: Reprogram bridge prefetch registers on resume" by Daniel Drake. After apply the patch, the ethernet adapter works fine before suspend and after resume. So, we can revert the workaround after the commit "PCI: Reprogram bridge prefetch registers on resume" is merged into main tree. This patch reverts commit 7bb05b85bc2d1a1b647b91424b2ed4a18e6ecd81 "r8169: don't use MSI-X on RTL8106e".
