2020-07-24iommu/vt-d: Skip TE disabling on quirky gfx dedicated iommuLu Baolu2-0/+28
The VT-d spec requires (10.4.4 Global Command Register, TE field) that: Hardware implementations supporting DMA draining must drain any in-flight DMA read/write requests queued within the Root-Complex before completing the translation enable command and reflecting the status of the command through the TES field in the Global Status register. Unfortunately, some integrated graphic devices fail to do so after some kind of power state transition. As the result, the system might stuck in iommu_disable_translation(), waiting for the completion of TE transition. This provides a quirk list for those devices and skips TE disabling if the qurik hits.

2020-07-24iommu/vt-d: Add page response ops supportLu Baolu2-0/+100
After page requests are handled, software must respond to the device which raised the page request with the result. This is done through the iommu ops.page_response if the request was reported to outside of vendor iommu driver through iommu_report_device_fault(). This adds the VT-d implementation of page_response ops.

2020-07-24iommu/vt-d: Report page request faults for guest SVALu Baolu1-18/+85
A pasid might be bound to a page table from a VM guest via the iommu ops.sva_bind_gpasid. In this case, when a DMA page fault is detected on the physical IOMMU, we need to inject the page fault request into the guest. After the guest completes handling the page fault, a page response need to be sent back via the iommu ops.page_response(). This adds support to report a page request fault. Any external module which is interested in handling this fault should regiester a notifier with iommu_register_device_fault_handler().

2020-07-24iommu/vt-d: Disable multiple GPASID-dev bindJacob Pan1-13/+9
For the unlikely use case where multiple aux domains from the same pdev are attached to a single guest and then bound to a single process (thus same PASID) within that guest, we cannot easily support this case by refcounting the number of users. As there is only one SL page table per PASID while we have multiple aux domains thus multiple SL page tables for the same PASID. Extra unbinding guest PASID can happen due to race between normal and exception cases. Termination of one aux domain may affect others unless we actively track and switch aux domains to ensure the validity of SL page tables and TLB states in the shared PASID entry. Support for sharing second level PGDs across domains can reduce the complexity but this is not available due to the limitations on VFIO container architecture. We can revisit this decision once sharing PGDs are available. Overall, the complexity and potential glitch do not warrant this unlikely use case thereby removed by this patch.

2020-07-24iommu/vt-d: Warn on out-of-range invalidation addressJacob Pan1-3/+2
For guest requested IOTLB invalidation, address and mask are provided as part of the invalidation data. VT-d HW silently ignores any address bits below the mask. SW shall also allow such case but give warning if address does not align with the mask. This patch relax the fault handling from error to warning and proceed with invalidation request with the given mask.

2020-07-24iommu/vt-d: Fix devTLB flush for vSVALiu Yi L1-10/+21
For guest SVA usage, in order to optimize for less VMEXIT, guest request of IOTLB flush also includes device TLB. On the host side, IOMMU driver performs IOTLB and implicit devTLB invalidation. When PASID-selective granularity is requested by the guest we need to derive the equivalent address range for devTLB instead of using the address information in the UAPI data. The reason for that is, unlike IOTLB flush, devTLB flush does not support PASID-selective granularity. This is to say, we need to set the following in the PASID based devTLB invalidation descriptor: - entire 64 bit range in address ~(0x1 << 63) - S bit = 1 (VT-d CH 6.5.2.6). Without this fix, device TLB flush range is not set properly for PASID selective granularity. This patch also merged devTLB flush code for both implicit and explicit cases.

2020-07-24iommu/vt-d: Handle non-page aligned addressLiu Yi L1-2/+19
Address information for device TLB invalidation comes from userspace when device is directly assigned to a guest with vIOMMU support. VT-d requires page aligned address. This patch checks and enforce address to be page aligned, otherwise reserved bits can be set in the invalidation descriptor. Unrecoverable fault will be reported due to non-zero value in the reserved bits.

2020-07-24iommu/vt-d: Fix PASID devTLB invalidationJacob Pan1-1/+10
DevTLB flush can be used for both DMA request with and without PASIDs. The former uses PASID#0 (RID2PASID), latter uses non-zero PASID for SVA usage. This patch adds a check for PASID value such that devTLB flush with PASID is used for SVA case. This is more efficient in that multiple PASIDs can be used by a single device, when tearing down a PASID entry we shall flush only the devTLB specific to a PASID.

These fixes avoid using the console system where we have been provided an alternative (safer) way to interact with the user and, if using the console system in unavoidable, use oops_in_progress for deadlock avoidance. These fixes also ensure kdb honours the console enable flag. Also included is a fix that wraps kgdb trap handling in an RCU read lock to avoids triggering diagnostic warnings.

2020-06-26kdb: Switch to use safer dbg_io_ops over console APIsSumit Garg3-18/+19
In kgdb context, calling console handlers aren't safe due to locks used in those handlers which could in turn lead to a deadlock. Although, using oops_in_progress increases the chance to bypass locks in most console handlers but it might not be sufficient enough in case a console uses more locks (VT/TTY is good example). Currently when a driver provides both polling I/O and a console then kdb will output using the console. We can increase robustness by using the currently active polling I/O driver (which should be lockless) instead of the corresponding console. For several common cases (e.g. an embedded system with a single serial port that is used both for console output and debugger I/O) this will result in no console handler being used. In order to achieve this we need to reverse the order of preference to use dbg_io_ops (uses polling I/O mode) over console APIs. So we just store "struct console" that represents debugger I/O in dbg_io_ops and while emitting kdb messages, skip console that matches dbg_io_ops console in order to avoid duplicate messages. After this change, "is_console" param becomes redundant and hence removed.

2020-06-26i2c: core: check returned size of emulated smbus block readMans Rullgard1-0/+7
If the i2c bus driver ignores the I2C_M_RECV_LEN flag (as some of them do), it is possible for an I2C_SMBUS_BLOCK_DATA read issued on some random device to return an arbitrary value in the first byte (and nothing else). When this happens, i2c_smbus_xfer_emulated() will happily write past the end of the supplied data buffer, thus causing Bad Things to happen. To prevent this, check the size before copying the data block and return an error if it is too large.

The napi_gro_receive function no longer returns GRO_DROP ever, making handling GRO_DROP dead code. This commit removes that dead code. Further, it's not even clear that device drivers have any business in taking action after passing off received packets; that's arguably out of their hands. In this case, too, the non-gro path didn't bother checking the return value. Plus, this had some clunky debugging functions that duplicated code from elsewhere and was generally pretty messy.

The sja1105_gating_cfg_time_to_interval function does this, as per the comments: /* The gate entries contain absolute times in their e->interval field. Convert * that to proper intervals (i.e. "0, 5, 10, 15" to "5, 5, 5, 5"). */ To perform that task, it iterates over gating_cfg->entries, at each step updating the interval of the _previous_ entry. So one interval remains to be updated at the end of the loop: the last one (since it isn't "prev" for anyone else). But there was an erroneous check, that the last element's interval should not be updated if it's also the only element. I'm not quite sure why that check was there, but it's clearly incorrect, as a tc-gate schedule with a single element would get an e->interval of zero, regardless of the duration requested by the user. The switch wouldn't even consider this configuration as valid: it will just drop all traffic that matches the rule.
