2019-09-06iommu/amd: Fix race in increase_address_space()Joerg Roedel1-5/+11
After the conversion to lock-less dma-api call the increase_address_space() function can be called without any locking. Multiple CPUs could potentially race for increasing the address space, leading to invalid domain->mode settings and invalid page-tables. This has been happening in the wild under high IO load and memory pressure. Fix the race by locking this operation. The function is called infrequently so that this does not introduce a performance regression in the dma-api path again.

2019-09-06iommu/amd: Flush old domains in kdump kernelStuart Hayes1-0/+24
When devices are attached to the amd_iommu in a kdump kernel, the old device table entries (DTEs), which were copied from the crashed kernel, will be overwritten with a new domain number. When the new DTE is written, the IOMMU is told to flush the DTE from its internal cache--but it is not told to flush the translation cache entries for the old domain number. Without this patch, AMD systems using the tg3 network driver fail when kdump tries to save the vmcore to a network system, showing network timeouts and (sometimes) IOMMU errors in the kernel log. This patch will flush IOMMU translation cache entries for the old domain when a DTE gets overwritten with a new domain number.

2019-09-05drm/vmwgfx: Fix double free in vmw_recv_msg()Dan Carpenter1-5/+3
We recently added a kfree() after the end of the loop: if (retries == RETRIES) { kfree(reply); return -EINVAL; } There are two problems. First the test is wrong and because retries equals RETRIES if we succeed on the last iteration through the loop. Second if we fail on the last iteration through the loop then the kfree is a double free. When you're reading this code, please note the break statement at the end of the while loop. This patch changes the loop so that if it's not successful then "reply" is NULL and we can test for that afterward.

2019-09-04virtio-net: lower min ring num_free for efficiency? jiang1-1/+1
This change lowers ring buffer reclaim threshold from 1/2*queue to budget for better performance. According to our test with qemu + dpdk, packet dropping happens when the guest is not able to provide free buffer in avail ring timely with default 1/2*queue. The value in the patch has been tested and does show better performance. Test setup: iperf3 to generate packets to guest (total 30mins, pps 400k, UDP) avg packets drop before: 2842 avg packets drop after: 360(-87.3%) Further, current code suffers from a starvation problem: the amount of work done by try_fill_recv is not bounded by the budget parameter, thus (with large queues) once in a while userspace gets blocked for a long time while queue is being refilled. Trigger refills earlier to make sure the amount of work to do is limited. Signed-off-by: jiangkidd <jiangkidd@hotmail.com> Acked-by: Jason Wang <jasowang@redhat.com> Acked-by: Michael S.

2019-09-04dmaengine: rcar-dmac: Fix DMACHCLR handling if iommu is mappedYoshihiro Shimoda1-9/+19
The commit 20c169aceb45 ("dmaengine: rcar-dmac: clear pertinence number of channels") forgets to clear the last channel by DMACHCLR in rcar_dmac_init() (and doesn't need to clear the first channel) if iommu is mapped to the device. So, this patch fixes it by using "channels_mask" bitfield. Note that the hardware and driver don't support more than 32 bits in DMACHCLR register anyway, so this patch should reject more than 32 channels in rcar_dmac_parse_of().

For the Spreadtrum DMA link-list mode, when the DMA engine got a slave hardware request, which will trigger the DMA engine to load the DMA configuration from the link-list memory automatically. But before the slave hardware request, the slave will get an incorrect residue due to the first node used to trigger the link-list was configured as the last source address and destination address. Thus we should make sure the first node was configured the start source address and destination address, which can fix this issue.

2019-09-03Revert "mmc: core: do not retry CMD6 in __mmc_switch()"Jan Kaisrlik1-1/+1
Turns out the commit 3a0681c7448b ("mmc: core: do not retry CMD6 in __mmc_switch()") breaks initialization of a Toshiba THGBMNG5 eMMC card, when using the meson-gx-mmc.c driver on a custom board based on Amlogic A113D. The CMD6 that switches the card into HS200 mode is then one that fails and according to the below printed messages from the log: [ 1.648951] mmc0: mmc_select_hs200 failed, error -84 [ 1.648988] mmc0: error -84 whilst initialising MMC card After some analyze, it turns out that adding a delay of ~5ms inside mmc_select_bus_width() but after mmc_compare_ext_csds() has been executed, also fixes the problem. Adding yet some more debug code, trying to figure out if potentially the card could be in a busy state, both by using CMD13 and ->card_busy() ops concluded that this was not the case. Therefore, let's simply revert the commit that dropped support for retrying of CMD6, as this also fixes the problem.

Global pages support is removed from VT-d spec 3.0. Since global pages G flag only affects first-level paging structures and because DMA request with PASID are only supported by VT-d spec. 3.0 and onward, we can safely remove global pages support. For kernel shared virtual address IOTLB invalidation, PASID granularity and page selective within PASID will be used. There is no global granularity supported. Without this fix, IOTLB invalidation will cause invalid descriptor error in the queued invalidation (QI) interface.

2019-09-01net: aquantia: fix out of memory condition on rx sideDmitry Bogdanov1-1/+2
On embedded environments with hard memory limits it is a normal although rare case when skb can't be allocated on rx part under high traffic. In such OOM cases napi_complete_done() was not called. So the napi object became in an invalid state like it is "scheduled". Kernel do not re-schedules the poll of that napi object. Consequently, kernel can not remove that object the system hangs on `ifconfig down` waiting for a poll. We are fixing this by gracefully closing napi poll routine with correct invocation of napi_complete_done. This was reproduced with artificially failing the allocation of skb to simulate an "out of memory" error case and check that traffic does not get stuck.

Not declaring this causes some kernel configurations to fail on interface up, because request_threaded_irq returned an err code.

2019-08-31net: stmmac: dwmac-rk: Don't fail if phy regulator is absentChen-Yu Tsai1-4/+2
The devicetree binding lists the phy phy as optional. As such, the driver should not bail out if it can't find a regulator. Instead it should just skip the remaining regulator related code and continue on normally. Skip the remainder of phy_power_on() if a regulator supply isn't available. This also gets rid of the bogus return code.

2019-08-30Revert "iommu/vt-d: Avoid duplicated pci dma alias consideration"Lu Baolu1-2/+53
This reverts commit 557529494d79f3f1fadd486dd18d2de0b19be4da. Commit 557529494d79f ("iommu/vt-d: Avoid duplicated pci dma alias consideration") aimed to address a NULL pointer deference issue happened when a thunderbolt device driver returned unexpectedly. Unfortunately, this change breaks a previous pci quirk added by commit cc346a4714a59 ("PCI: Add function 1 DMA alias quirk for Marvell devices"), as the result, devices like Marvell 88SE9128 SATA controller doesn't work anymore. We will continue to try to find the real culprit mentioned in 557529494d79f, but for now we should revert it to fix current breakage.
