[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] kdump-error-handler.service: Remove ExecStopPost
by Kairui Song 27 Nov '19

27 Nov '19

Currently "systemctl --fail --no-block default" will be executed on kdump-error-handler exit due to the config ExecStopPost. This may makes systemd try to isolate to the default target again, if both final_action or failure_action failed to terminates the system. The execute chain will be like: initrd.target -> kdump.sh (failed) -> kdump-error-handler.service -> failure_action -> final_action -> ExecStopPost (go to initrd.target again and loop infinitely) Currently, reboot/shutdown/halt is guarenteen to be called by either by executing failure_action or final_action. So the loop will be stopped. However none of the reboot/shutdown/halt call is blocking so it might have race issue, and this ExecStopPost config is not useful after all. Just drop the ExecStopPost to fix this potential issue. --- dracut-kdump-error-handler.service | 1 - 1 file changed, 1 deletion(-) diff --git a/dracut-kdump-error-handler.service b/dracut-kdump-error-handler.service index 32b74ab..a23b75e 100644 --- a/dracut-kdump-error-handler.service +++ b/dracut-kdump-error-handler.service @@ -21,7 +21,6 @@ Environment=DRACUT_SYSTEMD=1 Environment=NEWROOT=/sysroot WorkingDirectory=/ ExecStart=/bin/kdump-error-handler.sh -ExecStopPost=-/usr/bin/systemctl --fail --no-block default Type=oneshot StandardInput=tty-force StandardOutput=inherit -- 2.23.0

[PATCH] mkdumprd: greatly simplify dracut args parsing
by Kairui Song 25 Nov '19

25 Nov '19

Previously dracut_args is stored as an array in the shell code, so we can just pass this array as argument to dracut. But when trying to append new dracut argument, we have to manually handle the quotes and spaces to ensure the appended argument is splitted into array elements in the right way. This is complex and hard to read or maintain. Instead, just store the dracut_args as a plain string, and let xargs help parse it and call dracut. Simply passing $dracut_args or "$dracut_args" will either let dracut consider the whole string as a single argument, or loss all the quotes. xargs can handle it well and cover more corner cases. Eg. one corner case before, if we have: dracut_args --mount "/dev/sda1 /mnt/test xfs rw" Kdump will fail, because the function add_dracut_arg() will wrongly change the arguments into: (Notice the extra space.) dracut_args --mount " /dev/sda1 /mnt/test xfs rw" Instead of fixing it just use xargs instead. Tested with above config and multiple other dracut_args values.

I have no concrete example, but since the mutiple pre scripts introduced here we should consider the order of them. make some convention for example to document that the pre.d/* runs in alphabet order or add some prefix like 00, 01.. In another word, at least should document about the running order is the same as the result of the command "sort" Thanks Dave

If in the future one want to add a new pre/post script/binary to be run after some specific files existed, then there is no way to do that reliably.

Bash's pattern matching expands files in the alphabetical order. Quoted from man 1 bash: Pathname Expansion After word splitting, unless the -f option has been set, bash scans each word for the characters *, ?, and [. If one of these characters appears, then the word is regarded as a pattern, and replaced with an alphabetically sorted list of filenames matching the pattern (see Pattern Matching below). /etc/rc.d/rc in initscripts package relies on this: https://github.com/fedora-sysv/initscripts/blob/164d1ede7161233a2a2fe6e4cf4… > > > > > > > +} > > > + > > > # Default sysctl parameters should suffice for kdump kernel. > > > # Remove custom configurations sysctl.conf & sysctl.d/* > > > remove_sysctl_conf() { > > > -- > > > 1.8.3.1 > > > _______________________________________________ > > > kexec mailing list -- kexec(a)lists.fedoraproject.org > > > To unsubscribe send an email to kexec-leave(a)lists.fedoraproject.org > > > Fedora Code of Conduct: > > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > > > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > > > List Archives: > > > https://lists.fedoraproject.org/archives/list/kexec@lists.fedoraproject.or > > g > > > > -- > > Best Regards, > > Kairui Song > > _______________________________________________ > > kexec mailing list -- kexec(a)lists.fedoraproject.org > > To unsubscribe send an email to kexec-leave(a)lists.fedoraproject.org > > Fedora Code of Conduct: > > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > > List Archives: > > > https://lists.fedoraproject.org/archives/list/kexec@lists.fedoraproject.or > > g > _______________________________________________ > kexec mailing list -- kexec(a)lists.fedoraproject.org > To unsubscribe send an email to kexec-leave(a)lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/kexec@lists.fedoraproject.or > g

Maybe, only symbolic-link files are included into the kdump initramfs? As below, there is inst_symlink() in /usr/lib/dracut/dracut-init.sh, and so I guess it would at least be OK if we use inst_symlink, but install_multiple() could handle symbolic-link files appropreately. Could you check the behavior? inst_symlink() { local _hostonly_install if [[ "$1" == "-H" ]]; then _hostonly_install="-H" shift fi [[ -e ${initdir}/"${2:-$1}" ]] && return 0 # already there [[ -L $1 ]] || return 1 $DRACUT_INSTALL ${initdir:+-D "$initdir"} ${loginstall:+-L "$loginstall"} ${DRACUT_RESOLVE_DEPS:+-l} ${DRACUT_FIPS_MODE:+-f} ${_hostonly_install:+-H} "$@" (($? != 0)) && derror FAILED: $DRACUT_INSTALL ${initdir:+-D "$initdir"} ${loginstall:+-L "$loginstall"} ${DRACUT_RESOLVE_DEPS:+-l} ${DRACUT_FIPS_MODE:+-f} ${_hostonly_install:+-H} "$@" || : } inst_multiple() { local _ret $DRACUT_INSTALL ${initdir:+-D "$initdir"} -a ${loginstall:+-L "$loginstall"} ${DRACUT_RESOLVE_DEPS:+-l} ${DRACUT_FIPS_MODE:+-f} "$@" _ret=$?
