[Crash-utility] [ANNOUNCE] crash gcore command, version 1.5.1 is released

[d.hatayama at fujitsu.com]

This is the release of crash gcore command, version 1.5.1.

This release includes the following 2 bug fixes.

ChangeLog:

  - Fix the invalid structure member failure of
    thread_struct_fpsimd_state caused by the commit
    65896545b69ffaac947c12e11d3dcc57fd1fb772 merged at v4.17-rc2
    ("arm64: uaccess: Fix omissions from usercopy whitelist") that
    changed struct thread_struct. Without this fix, gcore command
    fails with the following error message:

        crash> gcore 2190

          gcore: invalid structure member offset: thread_struct_fpsimd_state
             FILE: libgcore/gcore_arm64.c  LINE: 46  FUNCTION: fpr_get()

          [./crash] error trace: ffff81c44c8c => ffff81c48fb8 => 51afd8 => 51af50

        51af50: OFFSET_verify.part.28+72
        51afd8: store_module_kallsyms_v2.part.29+0

          Failed.

  - Fix the invalid structure size failure of pid_link on v4.19 and
    newer kernel introduced by the commit 2c4704756cab ("pids: Move
    the pgrp and session pid pointers from task_struct to
    signal_struct") that removed struct pid_link array from
    task_struct and added struct pid array into signal_struct. Without
    this fix, gcore command fails with the following error message:

        gcore: invalid structure size: pid_link
               FILE: libgcore/gcore_coredump_table.c  LINE: 423  FUNCTION: pid_alive()

        [./crash] error trace: 7f4a7a6762b8 => 7f4a7a676e0f => 53b391 => 53b316

          53b316: SIZE_verify.part.31+70
          53b391: SIZE_verify+49

        gcore: invalid structure size: pid_link
               FILE: libgcore/gcore_coredump_table.c  LINE: 423  FUNCTION: pid_alive()

        Failed.
