DEBUG_PAGEALLOC removes the valid bit of page table entries to prevent any access to unallocated memory. Hibernate uses this as a hint that those pages don't need to be saved/restored. This patch adds the kernel_page_present() function it uses. hibernate.c copies the resume kernel's linear map for use during restore. Add _copy_pte() to fill-in the holes made by DEBUG_PAGEALLOC in the resume kernel, so we can restore data the original kernel had at these addresses. Finally, DEBUG_PAGEALLOC means the linear-map alias of KERNEL_START to KERNEL_END may have holes in it, so we can't lazily clean this whole area to the PoC. Only clean the new mmuoff region, and the kernel/kvm idmaps. This reverts commit da24eb1f. Reported-by:

Resume from hibernate needs to clean any text executed by the kernel with the MMU off to the PoC. Collect these functions together into the .idmap.text section as all this code is tightly coupled and also needs the same cleaning after resume. Data is more complicated, secondary_holding_pen_release is written with the MMU on, clean and invalidated, then read with the MMU off. In contrast __boot_cpu_mode is written with the MMU off, the corresponding cache line is invalidated, so when we read it with the MMU on we don't get stale data. These cache maintenance operations conflict with each other if the values are within a Cache Writeback Granule (CWG) of each other. Collect the data into two sections .mmuoff.data.read and .mmuoff.data.write, the linker script ensures mmuoff.data.write section is aligned to the architectural maximum CWG of 2KB. Signed-off-by:

The ARMv8 architecture allows execute-only user permissions by clearing the PTE_UXN and PTE_USER bits. However, the kernel running on a CPU implementation without User Access Override (ARMv8.2 onwards) can still access such page, so execute-only page permission does not protect against read(2)/write(2) etc. accesses. Systems requiring such protection must enable features like SECCOMP. This patch changes the arm64 __P100 and __S100 protection_map[] macros to the new __PAGE_EXECONLY attributes. A side effect is that pte_user() no longer triggers for __PAGE_EXECONLY since PTE_USER isn't set. To work around this, the check is done on the PTE_NG bit via the pte_ng() macro. VM_READ is also checked now for page faults. Reviewed-by:

Whenever we are hitting a kprobe from a none-kprobe debug exception handler, we hit an infinite occurrences of "Unexpected kernel single-step exception at EL1" PSTATE.D is debug exception mask bit. It is set whenever we enter into an exception mode. When it is set then Watchpoint, Breakpoint, and Software Step exceptions are masked. However, software Breakpoint Instruction exceptions can never be masked. Therefore, if we ever execute a BRK instruction, irrespective of D-bit setting, we will be receiving a corresponding breakpoint exception. For example: - We are executing kprobe pre/post handler, and kprobe has been inserted in one of the instruction of a function called by handler. So, it executes BRK instruction and we land into the case of KPROBE_REENTER. (This case is already handled by current code) - We are executing uprobe handler or any other BRK handler such as in WARN_ON (BRK BUG_BRK_IMM), and we trace that path using kprobe.So, we enter into kprobe breakpoint handler,from another BRK handler.(This case is not being handled currently) In all such cases kprobe breakpoint exception will be raised when we were already in debug exception mode. SPSR's D bit (bit 9) shows the value of PSTATE.D immediately before the exception was taken. So, in above example cases we would find it set in kprobe breakpoint handler. Single step exception will always be followed by a kprobe breakpoint exception.However, it will only be raised gracefully if we clear D bit while returning from breakpoint exception. If D bit is set then, it results into undefined exception and when it's handler enables dbg then single step exception is generated, however it will never be handled(because address does not match and therefore treated as unexpected). This patch clears D-flag unconditionally in setup_singlestep, so that we can always get single step exception correctly after returning from breakpoint exception. Additionally, it also removes D-flag set statement for KPROBE_REENTER return path, because debug exception for KPROBE_REENTER will always take place in a debug exception state. So, D-flag will already be set in this case. Acked-by:

Currently, x25 and x26 hold the physical addresses of idmap_pg_dir and swapper_pg_dir, respectively, when running early boot code. But having registers with 'global' scope in files that contain different sections with different lifetimes, and that are called by different CPUs at different times is a bit messy, especially since stashing the values does not buy us anything in terms of code size or clarity. So simply replace each reference to x25 or x26 with an adrp instruction referring to idmap_pg_dir or swapper_pg_dir directly. Acked-by:

These objects are set during initialization, thereafter are read only. Previously I only want to mark vdso_pages, vdso_spec, vectors_page and cpu_ops as __read_mostly from performance point of view. Then inspired by Kees's patch[1] to apply more __ro_after_init for arm, I think it's better to mark them as __ro_after_init. What's more, I find some more objects are also read only after init. So apply __ro_after_init to all of them. This patch also removes global vdso_pagelist and tries to clean up vdso_spec[] assignment code.

__dma_* routines have been converted to use start and size instread of start and end addresses. The patch was origianlly for adding __clean_dcache_area_poc() which will be used in pmem driver to clean dcache to the PoC(Point of Coherency) in arch_wb_cache_pmem(). The functionality of __clean_dcache_area_poc() was equivalent to __dma_clean_range(). The difference was __dma_clean_range() uses the end address, but __clean_dcache_area_poc() uses the size to clean. Thus, __clean_dcache_area_poc() has been revised with a fallthrough function of __dma_clean_range() after the change that __dma_* routines use start and size instead of using start and end. As a consequence of using start and size, the name of __dma_* routines has also been altered following the terminology below: area: takes a start and size range: takes a start and end Reviewed-by:

Currently ret_fast_syscall, work_pending, and ret_to_user form an ad-hoc state machine that can be difficult to reason about due to duplicated code and a large number of branch targets. This patch factors the common logic out into the existing do_notify_resume function, converting the code to C in the process, making the code more legible. This patch tries to closely mirror the existing behaviour while using the usual C control flow primitives. As local_irq_{disable,enable} may be instrumented, we balance exception entry (where we will almost most likely enable IRQs) with a call to trace_hardirqs_on just before the return to userspace.

In break_before_make_ttbr_switch we perform broadcast TLB maintenance for the inner shareable domain, and use a DSB ISH to complete this. However, at the point we execute this, secondary CPUs are either physically offline, or executing code outside of the kernel. Upon entering the kernel, secondary CPUs will invalidate their TLBs before enabling their MMUs. Thus we do not need to invalidate TLBs of other CPUs, and as with idmap_cpu_replace_ttbr1 we can reduce the scope of maintenance to the TLBs of the local CPU. This keeps our TLB maintenance code consistent, and is a minor optimisation. Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Acked-by:

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing. Acked-by:

When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line). Signed-off-by:

The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.
