[PATCH 001/110] mm: fix double page fault on arm64 if PTE_AF is cleared
by Yang Yingliang 04 Nov '20

04 Nov '20

From: Jia He <justin.he(a)arm.com> stable inclusion from linux-4.19.149 commit 8579a0440381353e0a71dd6a4d4371be8457eac4 -------------------------------- [ Upstream commit 83d116c53058d505ddef051e90ab27f57015b025 ] When we tested pmdk unit test [1] vmmalloc_fork TEST3 on arm64 guest, there will be a double page fault in __copy_from_user_inatomic of cow_user_page. To reproduce the bug, the cmd is as follows after you deployed everything: make -C src/test/vmmalloc_fork/ TEST_TIME=60m check Below call trace is from arm64 do_page_fault for debugging purpose: [ 110.016195] Call trace: [ 110.016826] do_page_fault+0x5a4/0x690 [ 110.017812] do_mem_abort+0x50/0xb0 [ 110.018726] el1_da+0x20/0xc4 [ 110.019492] __arch_copy_from_user+0x180/0x280 [ 110.020646] do_wp_page+0xb0/0x860 [ 110.021517] __handle_mm_fault+0x994/0x1338 [ 110.022606] handle_mm_fault+0xe8/0x180 [ 110.023584] do_page_fault+0x240/0x690 [ 110.024535] do_mem_abort+0x50/0xb0 [ 110.025423] el0_da+0x20/0x24 The pte info before __copy_from_user_inatomic is (PTE_AF is cleared): [ffff9b007000] pgd=000000023d4f8003, pud=000000023da9b003, pmd=000000023d4b3003, pte=360000298607bd3 As told by Catalin: "On arm64 without hardware Access Flag, copying from user will fail because the pte is old and cannot be marked young. So we always end up with zeroed page after fork() + CoW for pfn mappings. we don't always have a hardware-managed access flag on arm64." This patch fixes it by calling pte_mkyoung. Also, the parameter is changed because vmf should be passed to cow_user_page() Add a WARN_ON_ONCE when __copy_from_user_inatomic() returns error in case there can be some obscure use-case (by Kirill).

[PATCH 1/7] xen/events: add a proper barrier to 2-level uevent unmasking
by Yang Yingliang 02 Nov '20

02 Nov '20

From: Juergen Gross <jgross(a)suse.com> mainline inclusion from mainline-v5.10 commit 4d3fe31bd993ef504350989786858aefdb877daa category: bugfix bugzilla: NA CVE: CVE-2020-27673 -------------------------------- A follow-up patch will require certain write to happen before an event channel is unmasked. While the memory barrier is not strictly necessary for all the callers, the main one will need it. In order to avoid an extra memory barrier when using fifo event channels, mandate evtchn_unmask() to provide write ordering. The 2-level event handling unmask operation is missing an appropriate barrier, so add it. Fifo event channels are fine in this regard due to using sync_cmpxchg(). This is part of XSA-332.

[PATCH openEuler-1.0-LTS 0/5] kvm: arm64: emulate ID registers
by Yang Yingliang 29 Oct '20

29 Oct '20

In AArch64, guest will read the same values of the ID regsiters with host. Both of them read the values from arm64_ftr_regs. This patch series add support to emulate and configure ID registers so that we can control the value of ID registers that guest read. Peng Liang (5): arm64: add a helper function to traverse arm64_ftr_regs kvm: arm64: emulate the ID registers kvm: arm64: make ID registers configurable kvm: arm64: add KVM_CAP_ARM_CPU_FEATURE extension kvm: fix compile error when including linux/kvm.h arch/arm64/include/asm/cpufeature.h | 2 + arch/arm64/include/asm/kvm_host.h | 2 + arch/arm64/kernel/cpufeature.c | 13 ++++++ arch/arm64/kvm/sys_regs.c | 71 ++++++++++++++++++++++------- include/uapi/linux/kvm.h | 13 ++++++ virt/kvm/arm/arm.c | 23 ++++++++++ 6 files changed, 107 insertions(+), 17 deletions(-) -- 2.25.1
