With the few things it's be perfect. Please double-check with other Debian/Ubuntu patches and send them all upstream.

Thanks in advance o/

Why are we masking only this one and not the other dozen+ instances of read_conf/read_conf_or_die?

@anbe42 the Ubuntu tests are failing - it seems like the "update-secureboot-policy" change is causing some additional changes/output. Can you fix those up?

With that we should be good to land.

xuzhen · 2022-10-27T12:52:12Z

If we enroll the created key on Ubuntu, why we not do the same on other distributions?
And there is no need to enroll the key on computers that do not have SecureBoot enabled.

rebased onto additional fixes arising from discussion on the recently merged PRs, now all green ;-)

anbe42 · 2023-04-03T12:32:48Z

with that merged, all my open bugs and PRs should be addressed and most Debian issues should be resolved and upstreamed ;-)

there is no point in special casing a mismatching return code of 0

the bash idiom <(foo) relies on the /dev/fd -> /proc/self/fd symlink if /proc is not mounted, dkms status (and other actions) may fail with /usr/sbin/dkms: line ####: /dev/fd/##: No such file or directory https://bugs.debian.org/810665

…derr" This reverts commit 288f580.

skip building the module if kernelver does not satisfy BUILD_EXCLUSIVE_KERNEL_MIN <= kernelver <= BUILD_EXCLUSIVE_KERNEL_MAX Closes dkms-project#300

support build exclusion depending on kernel features being present/absent, e.g. BUILD_EXCLUSIVE_CONFIG="CONFIG_FOO !CONFIG_BAR" Closes dkms-project#219

this is a purely cosmetic change to get a "natural" processing order in case multiple kernels versions are installed, e.g. 4.1 < 4.2 < 4.10 < 5.0 instead of alphanumeric order, e.g. 4.1 < 4.10 < 4.2 < 5.0

Fixing shellcheck warnings/issues gets a huge 💯 👍 from me. Although let's keep those a separate follow-up PR.

It's very easy to follow the suggestions and break thing in unexpected ways - it has happened (both to me and friends) a number of times.

With the shellcheck commit dropped, this is ready to merge.

anbe42 · 2023-04-07T13:03:03Z

I've split the fixes for obvious errors from the shellcheck commit into separate verbose commits and left the quoting style changes for later.

dkms.in

dkms_autoinstaller

SC2070 (error): -n doesn't work with unquoted arguments. Quote or use [[ ]].

SC2157 (error): Argument to implicit -n is always true due to literal strings.

SC2071 (error): > is for string comparisons. Use -gt instead.

this is used in multiple case "$running_distribution" in ... statements that are independent of $addon_modules_dir

 # These can come from the environment or the config file
 [[ ! ${ADDON_MODULES_DIR} && -e /etc/sysconfig/module-init-tools ]] && . /etc/sysconfig/module-init-tools
 addon_modules_dir="${ADDON_MODULES_DIR}"
-[[ ! ${addon_modules_dir} ]] && running_distribution="$(distro_version)"


This looks right, but has a high risk of causing regressions. Let's merge it here and it can be reverted independently if needed.

anbe42 · 2023-04-24T10:52:54Z

With all my patches merged, what do are your plans for making a new release?

evelikov · 2023-04-27T14:29:53Z

No objections on my end although I have no idea what to do 😅

@scaronni can you share some pointers - be that here or throw them in a RELEASE.md file within git? Thanks o/

scaronni · 2023-04-27T15:02:24Z

Well, there is no rule, I got the repository as is 😄

I'll make a release now, but in general just bump the release in the Makefile and make a release whenever you think it's a good moment. I'm open for improvements!

Since version 3.0.11 <dkms-project/dkms#269>, dkms supports the [`BUILD_EXCLUSIVE_CONFIG`] option in dkms.conf to specify kernel configuration options which must be enabled in the targeted kernel. Add this option with `CONFIG_HID`, `CONFIG_INPUT_FF_MEMLESS`, and `CONFIG_POWER_SUPPLY`, since xpadneo will fail to modpost if any of these are disabled. If a user installs a kernel where these options are disabled, the module will not be built and a warning similar to the following is printed: Warning: The /var/lib/dkms/hid-xpadneo/v0.9-144-g9b3b696-dirty/6.8.0-rc2/x86_64/dkms.conf for module hid-xpadneo includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch/config. This indicates that it should not be built. dkms autoinstall on 6.8.0-rc2/x86_64 was skipped for hid-xpadneo Without this option, the module build would fail and the kernel package would fail to install, leaving the user with a partially installed kernel package (on Debian, at least).
