Re: [Crash-utility] [ANNOUNCE] crash gcore command, version 1.6.0 is released
Hi Hatayama-san,
Thank you for the new release.
-----Original Message-----
This is the release of crash gcore command, version 1.6.0.
This release includes the following 1 new feature and 2 bug fixes.
This is tested on the latest kernels on Fedora 33, RHEL8, RHEL7 and
RHEL6 on x86_64.
Note that ZRAM support is not included in this release because some
patch set is still needed in crash utility.
This means that there is no need to include your zram patchset to
the upcoming release of crash? We can wait for it during this week..
Hagio-san, could you update the description of crash gcore command
at https://crash-utility.github.io/extensions.html?
Yes, I will do.
Bhupesh and Lianbo,
My understanding is that we cannot remove (replace) the old version of gcore
(crash-gcore-command-1.5.1.tar.gz) on https://github.com/crash-utility/crash-extensions
because distributors might download it directly. so I will
- only add crash-gcore-command-1.6.0.tar.gz to the crash-extensions repo
(do not remove crash-gcore-command-1.5.1.tar.gz)
- update https://crash-utility.github.io/extensions.html to link to 1.6.0,
and etc.
If you have any problems, please let me know.
Thanks,
Kazu

- Fix failure of collecting vDSO mapping if compat vDSO is disabled
due to wrongly designed condition for compat tasks that tries to
determine vDSO mapping based on VDSO_HIGH_BASE. Without this patch,
vDSO mapping page is not collected for tasks running in 32-bit
compat mode and thus displaying backtrace by gdb's bt command for
the tasks could be incomplete.

- Fix failure of invalid structure member offset with the message
"gcore: invalid structure member offset:
thread_struct_io_bitmap_max" due to change of kernel data structure
for io bitmap by the commit <577d5cd7e585> ("x86/ioperm: Move
iobitmap data into a struct").
