Description:
 crash      - kernel debugging utility, allowing gdb like syntax
Closes: 843731 844831
Changes:
 crash (7.1.7-1) unstable; urgency=medium
 .
   * New upstream 7.1.7  (Closes: #843731):
 .
   * Remove -pie compile option (Closes: #844831)
 .
   * Set the default 32-bit MIPS HZ value to 100 if the in-kernel config data
     is unavailable, and have the "mach" command display the value.
 .
   * Enable SPARSEMEM support on 32-bit MIPS by setting SECTION_SIZE_BITS and
     MAX_PHYSMEM_BITS.
 .
   * Fix for Linux 4.9-rc1 commits 15f4eae70d365bba26854c90b6002aaabb18c8aa and
     c65eacbe290b8141554c71b2c94489e73ade8c8d, which have introduced a new
     CONFIG_THREAD_INFO_IN_TASK configuration.  This configuration moves each
     task's thread_info structure from the base of its kernel stack into its
     task_struct.  Without the patch, the crash session fails during
     initialization with the error "crash: invalid structure member offset:
     thread_info_cpu".
 .
   * Fixes for the gathering of the active task registers from 32-bit MIPS
     dumpfiles: (1) If ELF notes are not available, read them from the kernel's
     crash_notes.  (2) If an online CPUs did not save its ELF notes, then
     adjust the mapping of each ELF note to its CPU accordingly.
 .
   * Add support for "help -r" on 32-bit MIPS to display the registers for each
     CPU from a dumpfile.
 .
   * Fix for Linux 4.9-rc1 commit 0100301bfdf56a2a370c7157b5ab0fbf9313e1cd,
     which rewrote the x86_64 switch_to() code by embedding the call to
     __switch_to() inside a new __switch_to_asm() assembly code ENTRY()
     function.  Without the patch, the message "crash: cannot determine thread
     return address" gets displayed during initialization, and the "bt" command
     shows frame #0 starting at "schedule" instead of "__schedule".
 .
   * When each x86_64 per-cpu cpu_tss.x86_tss.ist[] array member (or in older
     kernels, each per-cpu init_tss.x86_hw_tss.ist[] array member), is compared
     with its associated per-cpu orig_ist.ist[] array member, ensure that both
     exception stack pointers have been initialized (non-NULL) before printing
     a WARNING message if they don't match.
 .
   * Fix for a possible segmentation violation when analyzing Linux 4.7 x86_64
     kernels that are configured with CONFIG_RANDOMIZE_BASE.  Depending upon
     the randomized starting address of the kernel text and static data, a
     segmentation violation may occur during session initialization, just after
     the patching of the gdb minimal_symbol values message.
 .
   * Restore the x86_64 "dis" command's symbolic translation of jump or call
     target addresses if the kernel was configured with CONFIG_RANDOMIZE_BASE.
 .
   * Fix for the 32-bit MIPS "bt" command to prevent an empty display (task
     header only) for an active task if the epc register in its exception frame
     contains 00000000.
 .
   * Fix for support of Linux 4.7 and later x86_64 ELF kdump vmcores from
     kernels configured with CONFIG_RANDOMIZE_BASE.  Without the patch, the
     crash session may fail during initialization with the message "crash:
     vmlinux and vmcore do not match!".
 .
   * Fix for the x86_64 "mach" command display of the vmemmap base address in
     Linux 4.9 and later kernels configured with CONFIG_RANDOMIZE_BASE.
     Without the patch, the command shows a value of ffffea0000000000 next to
     "KERNEL VMEMMAP BASE".
 .
   * Since the Linux 3.10 release, the kernel has offered the ability to create
     multiple independent ftrace buffers.  At present, however, the "trace.c"
     extension module is only able to extract the primary buffer.  This patch
     refactors the trace.c extension module so that the global instance is
     passed around as a parameter rather than accessing it directly, and then
     locates all of the available instances and extracts the data from each of
     them.
 .
   * Fix for the s390x "bt" command for active tasks.  Since the commit above
     in this crash-7.1.7 release that added support for the new
     CONFIG_THREAD_INFO_IN_TASK configuration, the backtrace of active tasks
     can be incomplete.
 .
   * In collaboration with an update to the /dev/crash kernel driver, fix for
     Linux 4.6 commit a7f8de168ace487fa7b88cb154e413cf40e87fc6, which allows
     the ARM64 kernel image to be loaded anywhere in physical memory.  Without
     the patch, attempting to run live on an ARM64 Linux 4.6 and later kernel
     may display the warning message "WARNING: cannot read linux_banner
     string", and then fails with the message "crash: vmlinux and /dev/crash do
     not match!".  Version 1.3 of the crash driver is required, which
     introduces a new ioctl command that retrieves the ARM64-only
     "kimage_voffset" value that is required for virtual-to-physical address
     translation.
 .
   * Update of the sample memory_driver/crash.c /dev/crash kernel driver to
     version 1.3, which adds support for Linux 4.6 and later ARM64 kernels,
     kernels configured with CONFIG_HARDENED_USERCOPY, and S390X kernels use
     xlate_dev_mem_ptr() and unxlate_dev_mem_ptr() instead of kmap() and
     kunmap().
