rd.route should use the name from kdump_setup_ifname
Resolves: bz1950932
Upstream: Fedora
Conflict: None
commit 8a33ffffbcaab4d1baabed889c2a063649dcbab8
Author: Coiby Xu <coxu@redhat.com>
Date: Thu May 6 09:20:27 2021 +0800
rd.route should use the name from kdump_setup_ifname
This fixes bz1854037 which happens because kexec-tools generates rd.route for
eth0 instead of for kdump-eth0,
1. "rd.route=168.63.129.16:10.0.0.1:eth0 rd.route=169.254.169.254:10.0.0.1:eth0" is passed to the dracut cmdline by kexec-tools
2. In the 2rd kernel, dracut/modules.d/35network-manager/nm-config.sh calls
/usr/libexec/nm-initrd-generator to generate two .nmconnection files
based on the dracut cmdline, i.e. kdump-eth0.nmconnection and eth0.nmconnection,
- /run/NetworkManager/system-connections/kdump-eth0.nmconnection

bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
upstream: fedora
resolves: bz2003832
conflict:
function load_kdump_kernel_key() not presented in rhel9,
so related patch hunk are removed.
commit 70978c00e5a573f0901ac404067eaea2c6536370
Author: Kairui Song <kasong@redhat.com>
Date: Wed Sep 8 17:20:51 2021 +0800
bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
only run in first kernel and depend on dracut, and dracut depends
on bash. So use '[[ ]]' to replace '[ ]'.
This is a batch update done with following command:
`sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`
and replaced [ ... -a ... ] with [[ ... ]] && [[ ... ]] manually.
See https://tldp.org/LDP/abs/html/testconstructs.html for more details
on '[[ ]]', it's more versatile, safer, and slightly faster than '[ ]'.
This will also help shfmt to clean up the code in later commits.

bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
upstream: fedora

commit 70978c00e5a573f0901ac404067eaea2c6536370
Author: Kairui Song <kasong@redhat.com>
Date: Wed Sep 8 17:20:51 2021 +0800
bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
only run in first kernel and depend on dracut, and dracut depends
on bash. So use '[[ ]]' to replace '[ ]'.
This is a batch update done with following command:
`sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`
and replaced [ ... -a ... ] with [[ ... ]] && [[ ... ]] manually.
See https://tldp.org/LDP/abs/html/testconstructs.html for more details
on '[[ ]]', it's more versatile, safer, and slightly faster than '[ ]'.
This will also help shfmt to clean up the code in later commits.

kdump-lib.sh: add a config value retrive helper
upstream: fedora
resolves: bz2003832
conflict: none
commit 09ccf88405793220af640c5317cbadb71cf03d36
Author: Kairui Song <kasong@redhat.com>
Date: Mon Aug 16 23:25:14 2021 +0800
kdump-lib.sh: add a config value retrive helper
Add a helper kdump_get_conf_val to replace get_option_value.
It can help cover more corner cases in the code, like when there are
multiple spaces in config file, config value separated by a tab,
heading spaces, or trailing comments.
And this uses "sed group command" and "sed hold buffer", make it much
faster than previous `grep <config> | tail -1`.
This helper is supposed to provide a universal way for kexec-tools
scripts to read in config value. Currently, different scripts are
reading the config in many different fragile ways.
For example, following codes are found in kexec-tools script code base:
1. grep ^force_rebuild $KDUMP_CONFIG_FILE
echo $_force_rebuild | cut -d' ' -f2
2. grep ^kdump_post $KDUMP_CONFIG_FILE | cut -d\ -f2
3. awk '/^sshkey/ {print $2}' $conf_file
4. grep ^path $KDUMP_CONFIG_FILE | cut -d' ' -f2-
1, 2, and 4 will fail if the space is replaced by, e.g. a tab
1 and 2 might fail if there are multiple spaces between config name
and config value:
"kdump_post /var/crash/scripts/kdump-post.sh"
A space will be read instead of config value.
1, 2, 3 will fail if there are space in file path, like:
"kdump_post /var/crash/scripts dir/kdump-post.sh"
4 will fail if there are trailing comments:
"path /var/crash # some comment here"
And all will fail if there are heading space,
" path /var/crash"
And all will most likely cause problems if the config file contains
the same option more than once.
And all of them are slower than the new sed call. Old get_option_value
is also very slow and doesn't handle heading space.
Although we never claim to support heading space or tailing comments
before, it's harmless to be more robust on config reading, and many
conf files in /etc support heading spaces. And have a faster and
safer config reading helper makes it easier to clean up the code.
