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()

- 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

53b391: SIZE_verify+49
gcore: invalid structure size: pid_link
FILE: libgcore/gcore_coredump_table.c LINE: 423 FUNCTION: pid_alive()
