-Cc: onestero(a)redhat.com
-Subject: [PATCH v2] Restore live system crash analysis for ARM64
-
-This v2 version simplifies the copy out of the kimage_voffset value
-to user-space per Oleg's suggestion.
-
-Upstream status: N/A
-
-Test: v2 version tested successfully with a modified crash utility
-
-The following Linux 4.6 commit breaks support for live system
-crash analysis on ARM64:
-
- commit a7f8de168ace487fa7b88cb154e413cf40e87fc6
- Author: Ard Biesheuvel <ard.biesheuvel(a)linaro.org>
- arm64: allow kernel Image to be loaded anywhere in physical memory
-
-The patchset drastically modified the kernel's virtual memory layout,
-where notably the static kernel text and data image was moved from the
-unity mapped region into the vmalloc region. Prior to Linux 4.6,
-the kernel's __virt_to_phys() function was this:
-
- #define __virt_to_phys(x) (((phys_addr_t)(x) - PAGE_OFFSET + PHYS_OFFSET))
-
-When running on a live system, the crash utility could determine PAGE_OFFSET
-by looking at the virtual addresses compiled into the vmlinux file, and
-PHYS_OFFSET can be determined by looking at /proc/iomem.
-
-As of Linux 4.6, it is done differently:
-
- #define __virt_to_phys(x) ({ \
- phys_addr_t __x = (phys_addr_t)(x); \
- __x & BIT(VA_BITS - 1) ? (__x & ~PAGE_OFFSET) + PHYS_OFFSET : \
- (__x - kimage_voffset); })
-
-The PAGE_OFFSET/PHYS_OFFSET section of the conditional expression is for
-traditional unity-mapped virtual addresses, but kernel text and static
-data requires the new "kimage_voffset" variable. Unfortunately, the
-contents of the new "kimage_voffset" variable is not available or
-calculatable from a user-space perspective, even with root privileges.
-
-At least the ARM64 developers made its contents available to modules
-with an EXPORT_SYMBOL(kimage_voffset) declaration. Accordingly, with
-a modification to the /dev/crash driver to return its contents, the
-crash utility can run on a live system.
-
-The patch allows for architecture-specific DEV_CRASH_ARCH_DATA ioctls
