[PATCH v2] iommu/vt-d: do not use flush-queue when caching-mode is on

by Nadav Amit

From: Nadav Amit <namit(a)vmware.com> When an Intel IOMMU is virtualized, and a physical device is passed-through to the VM, changes of the virtual IOMMU need to be propagated to the physical IOMMU. The hypervisor therefore needs to monitor PTE mappings in the IOMMU page-tables. Intel specifications provide "caching-mode" capability that a virtual IOMMU uses to report that the IOMMU is virtualized and a TLB flush is needed after mapping to allow the hypervisor to propagate virtual IOMMU mappings to the physical IOMMU. To the best of my knowledge no real physical IOMMU reports "caching-mode" as turned on. Synchronizing the virtual and the physical IOMMU tables is expensive if the hypervisor is unaware which PTEs have changed, as the hypervisor is required to walk all the virtualized tables and look for changes. Consequently, domain flushes are much more expensive than page-specific flushes on virtualized IOMMUs with passthrough devices. The kernel therefore exploited the "caching-mode" indication to avoid domain flushing and use page-specific flushing in virtualized environments. See commit 78d5f0f500e6 ("intel-iommu: Avoid global flushes with caching mode.") This behavior changed after commit 13cf01744608 ("iommu/vt-d: Make use of iova deferred flushing"). Now, when batched TLB flushing is used (the default), full TLB domain flushes are performed frequently, requiring the hypervisor to perform expensive synchronization between the virtual TLB and the physical one. Getting batched TLB flushes to use in such circumstances page-specific invalidations again is not easy, since the TLB invalidation scheme assumes that "full" domain TLB flushes are performed for scalability. Disable batched TLB flushes when caching-mode is on, as the performance benefit from using batched TLB invalidations is likely to be much smaller than the overhead of the virtual-to-physical IOMMU page-tables synchronization.

[PATCH v4] x86/sgx: Fix the call order of synchronize_srcu() in sgx_release()

by jarkko＠kernel.org

From: Jarkko Sakkinen <jarkko(a)kernel.org> The most trivial example of a race condition can be demonstrated with this example where mm_list contains just one entry: CPU A CPU B sgx_release() sgx_mmu_notifier_release() list_del_rcu() sgx_encl_release() synchronize_srcu() cleanup_srcu_struct() To fix this, call synchronize_srcu() before checking whether mm_list is empty in sgx_release(). Cc: stable(a)vger.kernel.org Fixes: 1728ab54b4be ("x86/sgx: Add a page reclaimer") Suggested-by: Sean Christopherson <seanjc(a)google.com> Suggested-by: Haitao Huang <haitao.huang(a)linux.intel.com> Signed-off-by: Jarkko Sakkinen <jarkko(a)kernel.org> --- v4: - Rewrite the commit message. - Just change the call order. *_expedited() is out of scope for this bug fix. v3: Fine-tuned tags, and added missing change log for v2. v2: Switch to synchronize_srcu_expedited(). arch/x86/kernel/cpu/sgx/driver.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/x86/kernel/cpu/sgx/driver.c b/arch/x86/kernel/cpu/sgx/driver.c index f2eac41bb4ff..53056345f5f8 100644 --- a/arch/x86/kernel/cpu/sgx/driver.c +++ b/arch/x86/kernel/cpu/sgx/driver.c @@ -65,11 +65,16 @@ static int sgx_release(struct inode *inode, struct file *file) spin_unlock(&encl->mm_lock); + /* + * The call is need even if the list empty, because sgx_encl_mmu_notifier_release() + * could have initiated a new grace period. + */ + synchronize_srcu(&encl->srcu); + /* The enclave is no longer mapped by any mm. */ if (!encl_mm) break; - synchronize_srcu(&encl->srcu); mmu_notifier_unregister(&encl_mm->mmu_notifier, encl_mm->mm); kfree(encl_mm); } -- 2.29.2
