2022-09-27ARM: dts: integrator: Fix DMA rangesLinus Walleij2-4/+5
A recent change affecting the behaviour of phys_to_dma() to actually require the device tree ranges to work unmasked a bug in the Integrator DMA ranges. The PL110 uses the CMA allocator to obtain coherent allocations from a dedicated 1MB video memory, leading to the following call chain: drm_gem_cma_create() dma_alloc_attrs() dma_alloc_from_dev_coherent() __dma_alloc_from_coherent() dma_get_device_base() phys_to_dma() translate_phys_to_dma() phys_to_dma() by way of translate_phys_to_dma() will nowadays not provide 1:1 mappings unless the ranges are properly defined in the device tree and reflected into the dev->dma_range_map. There is a bug in the device trees because the DMA ranges are incorrectly specified, and the patch uncovers this bug. Solution: - Fix the LB (logic bus) ranges to be 1-to-1 like they should have always been. - Provide a 1:1 dma-ranges attribute to the PL110. - Mark the PL110 display controller as DMA coherent. This makes the DMA ranges work right and makes the PL110 framebuffer work again.

2022-09-26x86/uaccess: avoid check_object_size() in copy_from_user_nmi()Kees Cook1-1/+1
The check_object_size() helper under CONFIG_HARDENED_USERCOPY is designed to skip any checks where the length is known at compile time as a reasonable heuristic to avoid "likely known-good" cases. However, it can only do this when the copy_*_user() helpers are, themselves, inline too. Using find_vmap_area() requires taking a spinlock. The check_object_size() helper can call find_vmap_area() when the destination is in vmap memory. If show_regs() is called in interrupt context, it will attempt a call to copy_from_user_nmi(), which may call check_object_size() and then find_vmap_area(). If something in normal context happens to be in the middle of calling find_vmap_area() (with the spinlock held), the interrupt handler will hang forever. The copy_from_user_nmi() call is actually being called with a fixed-size length, so check_object_size() should never have been called in the first place. Given the narrow constraints, just replace the __copy_from_user_inatomic() call with an open-coded version that calls only into the sanitizers and not check_object_size(), followed by a call to raw_copy_from_user().

2022-09-26powerpc/64s/radix: don't need to broadcast IPI for radix pmd collapse flushYang Shi1-9/+0
The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will move to use RCU instead of disabling local interrupts in fast-GUP. Using an IPI is the old-styled way of serializing against fast-GUP although it still works as expected now. And fast-GUP now fixed the potential race with THP collapse by checking whether PMD is changed or not. So IPI broadcast in radix pmd collapse flush is not necessary anymore. But it is still needed for hash TLB.

2022-09-23KVM: x86: Inject #UD on emulated XSETBV if XSAVES isn't enabledSean Christopherson2-0/+4
Inject #UD when emulating XSETBV if CR4.OSXSAVE is not set. This also covers the "XSAVE not supported" check, as setting CR4.OSXSAVE=1 #GPs if XSAVE is not supported (and userspace gets to keep the pieces if it forces incoherent vCPU state). Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks CR4.OSXSAVE before checking for intercepts. AMD'S APM implies that #UD has priority (says that intercepts are checked before #GP exceptions), while Intel's SDM says nothing about interception priority. However, testing on hardware shows that both AMD and Intel CPUs prioritize the #UD over interception.

2022-09-23KVM: x86: Always enable legacy FP/SSE in allowed user XFEATURESDr. David Alan Gilbert1-1/+7
Allow FP and SSE state to be saved and restored via KVM_{G,SET}_XSAVE on XSAVE-capable hosts even if their bits are not exposed to the guest via XCR0. Failing to allow FP+SSE first showed up as a QEMU live migration failure, where migrating a VM from a pre-XSAVE host, e.g. Nehalem, to an XSAVE host failed due to KVM rejecting KVM_SET_XSAVE. However, the bug also causes problems even when migrating between XSAVE-capable hosts as KVM_GET_SAVE won't set any bits in user_xfeatures if XSAVE isn't exposed to the guest, i.e. KVM will fail to actually migrate FP+SSE. Because KVM_{G,S}ET_XSAVE are designed to allowing migrating between hosts with and without XSAVE, KVM_GET_XSAVE on a non-XSAVE (by way of fpu_copy_guest_fpstate_to_uabi()) always sets the FP+SSE bits in the header so that KVM_SET_XSAVE will work even if the new host supports XSAVE.

2022-09-23KVM: x86: Reinstate kvm_vcpu_arch.guest_supported_xcr0Sean Christopherson3-10/+5
Reinstate the per-vCPU guest_supported_xcr0 by partially reverting commit 988896bb6182; the implicit assessment that guest_supported_xcr0 is always the same as guest_fpu.fpstate->user_xfeatures was incorrect. kvm_vcpu_after_set_cpuid() isn't the only place that sets user_xfeatures, as user_xfeatures is set to fpu_user_cfg.default_features when guest_fpu is allocated via fpu_alloc_guest_fpstate() => __fpstate_reset(). guest_supported_xcr0 on the other hand is zero-allocated. If userspace never invokes KVM_SET_CPUID2, supported XCR0 will be '0', whereas the allowed user XFEATURES will be non-zero. Practically speaking, the edge case likely doesn't matter as no sane userspace will live migrate a VM without ever doing KVM_SET_CPUID2. The primary motivation is to prepare for KVM intentionally and explicitly setting bits in user_xfeatures that are not set in guest_supported_xcr0. Because KVM_{G,S}ET_XSAVE can be used to svae/restore FP+SSE state even if the host doesn't support XSAVE, KVM needs to set the FP+SSE bits in user_xfeatures even if they're not allowed in XCR0, e.g. because XCR0 isn't exposed to the guest. At that point, the simplest fix is to track the two things separately (allowed save/restore vs. allowed XCR0).

The new KPTI rewrite code uses __create_pgd_mapping() to create a temporary pagetable. This happens in atomic context, after secondary CPUs are brought up and the kernel has left the SYSTEM_BOOTING state. Hence we try to acquire a mutex in atomic context, which is generally unsound (though benign in this case as the mutex should be free and all other CPUs are quiescent). This patch avoids the issue by pulling the mutex out of alloc_init_pud() and calling it at a higher level in the pagetable manipulation code. This allows it to be used without locking where one CPU is known to be in exclusive control of the machine, even after having left the SYSTEM_BOOTING state.

2022-09-19KVM: arm64: Use kmemleak_free_part_phys() to unregister hyp_mem_baseZenghui Yu1-1/+1
With commit 0c24e061196c ("mm: kmemleak: add rbtree and store physical address for objects allocated with PA"), kmemleak started to put the objects allocated with physical address onto object_phys_tree_root tree. The kmemleak_free_part() therefore no longer worked as expected on physically allocated objects (hyp_mem_base in this case) as it attempted to search and remove things in object_tree_root tree. Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This fixes an immediate crash when booting a KVM host in protected mode with kmemleak enabled.

2022-09-19MIPS: Loongson32: Fix PHY-mode being left unspecifiedSerge Semin1-8/+8
commit 0060c8783330 ("net: stmmac: implement support for passive mode converters via dt") has changed the plat->interface field semantics from containing the PHY-mode to specifying the MAC-PCS interface mode. Due to that the loongson32 platform code will leave the phylink interface uninitialized with the PHY-mode intended by the means of the actual platform setup. The commit-author most likely has just missed the arch-specific code to fix. Let's mend the Loongson32 platform code then by assigning the PHY-mode to the phy_interface field of the STMMAC platform data.

The lantiq WDT driver uses clk_get_io(), which is not exported, so export it to fix a build error: ERROR: modpost: "clk_get_io" [drivers/watchdog/lantiq_wdt.ko] undefined!
