[PATCH] mkdumprd: allow spaces after 'path' config phrase when network dump
by Kazuhito Hagio 26 May '22

26 May '22

Without this patch, when there are two or more spaces after 'path' configuration phrase with ssh or nfs setting, SAVE_PATH is set to '/var/crash' in mkdumprd, and in most cases kdump service fails to start. ssh kdump(a)192.168.122.1 path /kdump ^^ This behavior would be too sensitive and different from the other configurations. With this patch, mkdumprd allows such spaces.

[PATCH v2 0/4] Add selftest for kexec-tools
by Kairui Song 14 Aug '20

14 Aug '20

This patch series adds the VM based selftest framework for Fedora kexec-tools. Currently there are 3 test cases, more could be added later. And the usage and details are included in the document for selftest. This help do quick sanity check of new patches, also help debug issues when developing kexec-tools. The test output looks like this: ==== Starting all tests: ==== local-kdump nfs-kdump ssh-kdump ======== Running Test Case local-kdump ======== ---- Building image for: 0-local.sh ---- -------- Output image is: /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.img -------- Building log is: /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.img.log ---- Starting test VM: 0-local.sh ---- -------- Qemu cmdline: /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.qemu_cmd -------- Console log: /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.console -------- Test log: /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.output --------Test finished: local-kdump TEST PASSED You can retrive the verify the vmcore file using following command: ./scripts/copy-from-image.sh \ /home/kasong/fedpkg/kexec-tools/tests/output/local-kdump/0-local.img \ /var/crash/127.0.0.1-2020-07-31-06:58:44/vmcore ./ ======== Running Test Case nfs-kdump ======== ---- Building image for: 1-client.sh ---- -------- Output image is: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/1-client.img -------- Building log is: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/1-client.img.log ---- Building image for: 0-server.sh ---- -------- Output image is: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.img -------- Building log is: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.img.log ---- Starting VM: 0-server.sh ---- -------- Qemu cmdline: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.qemu_cmd -------- Console log: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.console -------- Test log: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.output ---- Starting test VM: 1-client.sh ---- -------- Qemu cmdline: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/1-client.qemu_cmd -------- Console log: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/1-client.console -------- Test log: /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/1-client.output --------Test finished: nfs-kdump TEST PASSED You can retrive the verify the vmcore file using following command: ./scripts/copy-from-image.sh \ /home/kasong/fedpkg/kexec-tools/tests/output/nfs-kdump/0-server.img \ /srv/nfs/var/crash/192.168.77.62-2020-07-31-07:03:12/vmcore ./ ======== Running Test Case ssh-kdump ======== ---- Building image for: 1-client.sh ---- -------- Output image is: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/1-client.img -------- Building log is: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/1-client.img.log ---- Building image for: 0-server.sh ---- -------- Output image is: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.img -------- Building log is: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.img.log ---- Starting VM: 0-server.sh ---- -------- Qemu cmdline: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.qemu_cmd -------- Console log: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.console -------- Test log: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.output ---- Starting test VM: 1-client.sh ---- -------- Qemu cmdline: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/1-client.qemu_cmd -------- Console log: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/1-client.console -------- Test log: /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/1-client.output --------Test finished: ssh-kdump TEST PASSED You can retrive the verify the vmcore file using following command: ./scripts/copy-from-image.sh \ /home/kasong/fedpkg/kexec-tools/tests/output/ssh-kdump/0-server.img \ /var/crash/192.168.77.62-2020-07-31-07:05:57/vmcore.flat ./ ======== Test results ======== ---------------- nfs-kdump: TEST PASSED ---------------- ssh-kdump: TEST PASSED ---------------- local-kdump: TEST PASSED Update from V1: -

[PATCH v2 0/4] Rework kernel image and initrd detection code and install hook
by Kairui Song 06 Aug '20

06 Aug '20

This patch series refactor kernel image and initrd detection, fix kdump service failure on some Fedora machines which use /boot/<machine-id>/<kver>/vmlinuz as kernel installation destination. Also cover the atomic corner case properly by refering BOOT_IMAGE= cmdline param for kernel image location. Also introduce a kernel install hook to clean up the initramfs properly on kernel uninstall. Update from V1: - Add the kdump initramfs clean up hook to make sure it work with different kernel installation style.
