3d96208 | Roberto Bergantinos Corpas | 04 February 2020, 10:32:56 UTC | sunrpc: expiry_time should be seconds not timeval When upcalling gssproxy, cache_head.expiry_time is set as a timeval, not seconds since boot. As such, RPC cache expiry logic will not clean expired objects created under auth.rpcsec.context cache. This has proven to cause kernel memory leaks on field. Using 64 bit variants of getboottime/timespec Expiration times have worked this way since 2010's c5b29f885afe "sunrpc: use seconds since boot in expiry cache". The gssproxy code introduced in 2012 added gss_proxy_save_rsc and introduced the bug. That's a while for this to lurk, but it required a bit of an extreme case to make it obvious.

273da5a | Thierry Reding | 04 February 2020, 13:59:25 UTC | drm/tegra: Reuse IOVA mapping where possible This partially reverts the DMA API support that was recently merged because it was causing performance regressions on older Tegra devices. Unfortunately, the cache maintenance performed by dma_map_sg() and dma_unmap_sg() causes performance to drop by a factor of 10. The right solution for this would be to cache mappings for buffers per consumer device, but that's a bit involved. Instead, we simply revert to the old behaviour of sharing IOVA mappings when we know that devices can do so (i.e. they share the same IOMMU domain).

But commit 751035b8dc06 ("PCI/ATS: Cache PASID Capability offset") changed pci_max_pasids() and pci_pasid_features() to use the PASID Capability of the VF device instead of the associated PF device. This leads to IOMMU bind failures when pci_max_pasids() and pci_pasid_features() are called for VFs. In pci_max_pasids() and pci_pasid_features(), always use the PF PASID Capability.

d1c9038 | Stephen Kitt | 24 January 2020, 18:33:16 UTC | Allow git builds of Sphinx When using a non-release version of Sphinx, from a local build (with improvements for kernel doc handling, why not), sphinx-build --version reports versions of the form sphinx-build 3.0.0+/4703d9119972 i.e. base version, a plus symbol, slash, and the start of the git hash of whatever repository the command is run in (no, not the hash that was used to build Sphinx!). This patch fixes the installation check in sphinx-pre-install to recognise such version output.

The UMIP handling was unintentionally dropped during a recent refactoring. Not flagging CR4.UMIP allows the guest to set its CR4.UMIP regardless of host support or userspace desires. On CPUs with UMIP support, including emulated UMIP, this allows the guest to enable UMIP against the wishes of the userspace VMM. On CPUs without any form of UMIP, this results in a failed VM-Enter due to invalid guest state.

It would certainly be possible to add these missing checks to nested_check_vm_execution_controls()/_vm_exit_controls()/.. but it seems preferable to keep eVMCS-specific stuff in eVMCS and reduce the impact on non-eVMCS guests by doing less unrelated checks.

31de3d2 | Vitaly Kuznetsov | 05 February 2020, 12:30:33 UTC | x86/kvm/hyper-v: move VMX controls sanitization out of nested_enable_evmcs() With fine grained VMX feature enablement QEMU>=4.2 tries to do KVM_SET_MSRS with default (matching CPU model) values and in case eVMCS is also enabled, fails. It would be possible to drop VMX feature filtering completely and make this a guest's responsibility: if it decides to use eVMCS it should know which fields are available and which are not. Hyper-V mostly complies to this, however, there are some problematic controls: SECONDARY_EXEC_VIRTUALIZE_APIC_ACCESSES VM_{ENTRY,EXIT}_LOAD_IA32_PERF_GLOBAL_CTRL which Hyper-V enables. As there are no corresponding fields in eVMCS, we can't handle this properly in KVM. This is a Hyper-V issue. Move VMX controls sanitization from nested_enable_evmcs() to vmx_get_msr(), and do the bare minimum (only clear controls which are known to cause issues). This allows userspace to keep setting controls it wants and at the same time hides them from the guest.

9b5e853 | Sean Christopherson | 24 January 2020, 23:07:22 UTC | KVM: x86: Take a u64 when checking for a valid dr7 value Take a u64 instead of an unsigned long in kvm_dr7_valid() to fix a build warning on i386 due to right-shifting a 32-bit value by 32 when checking for bits being set in dr7[63:32]. Alternatively, the warning could be resolved by rewriting the check to use an i386-friendly method, but taking a u64 fixes another oddity on 32-bit KVM. Beause KVM implements natural width VMCS fields as u64s to avoid layout issues between 32-bit and 64-bit, a devious guest can stuff vmcs12->guest_dr7 with a 64-bit value even when both the guest and host are 32-bit kernels. KVM eventually drops vmcs12->guest_dr7[63:32] when propagating vmcs12->guest_dr7 to vmcs02, but ideally KVM would not rely on that behavior for correctness.

8171cd6 | Paolo Bonzini | 22 January 2020, 13:36:09 UTC | KVM: x86: use raw clock values consistently Commit 53fafdbb8b21f ("KVM: x86: switch KVMCLOCK base to monotonic raw clock") changed kvmclock to use tkr_raw instead of tkr_mono. However, the default kvmclock_offset for the VM was still based on the monotonic clock and, if the raw clock drifted enough from the monotonic clock, this could cause a negative system_time to be written to the guest's struct pvclock. RHEL5 does not like it and (if it boots fast enough to observe a negative time value) it hangs. There is another thing to be careful about: getboottime64 returns the host boot time with tkr_mono frequency, and subtracting the tkr_raw-based kvmclock value will cause the wallclock to be off if tkr_raw drifts from tkr_mono. To avoid this, compute the wallclock delta from the current time instead of being clever and using getboottime64.
