This series converts udev to a virtual package, either provided by systemd or
eudev.
Starting with version 183, udev has been merged into systemd. This forces the
use of systemd as the init system if /dev is to be dynamically managed by
udev. eudev is a fork of udev, maintained by Gentoo, but isolated from
systemd, so it can be used with any init system.
Systemd has been bumped to v207 and a new eudev package has been added.
Version 1.3 of eudev is in sync with systemd v207.
The bump of systemd to v207 also introduces new options, like the activation
of the journal gateway.
In the end:
- if systemd is selected as init system, the /dev management will handled by
udev. No other choice possible.
- if busybox or SysV is chosen, the user can choose to manage /dev
statically, or dynamically using mdev or eudev.
Changes v6 -> v7:
- updated udev related symbols and improved help text in Config.in.legacy
(suggested by ThomasDS).
- removed redundant comments on dependencies for systemd and eudev
(suggested by ThomasDS).
- fixed packages not properly converted to BR2_PACKAGE_HAS_UDEV
(reported by SamuelM).
Changes v5 -> v6:
- fixed packages not properly converted to BR2_PACKAGE_HAS_UDEV
(reported by Samuel M.).
- forced inotify support in Linux if eudev is used for /dev management.
- forced inotify support in Linux if systemd is used as init system.
- updated information about systemd requirements.
Changes v4 -> v5:
- disabled systemd and eudev on avr32.
- reverted Busybox binaries overwrite fix.
Changes v3 -> v4:
- updated /dev management section in user manual.
- fixed indentation of conditionals in Makefiles (suggested by Thomas P).
- added missing comments on dependencies (suggested by Thomas P, Thomas DS).
- fixed some packages not being converted to BR2_PACKAGE_HAS_UDEV.
Changes v2 -> v3:
- reordered patches for better bisectability (suggested by Thomas).
- removed uClibc support for Systemd (suggested by Arnout).
- bumped systemd to v207 (no more backport patches).
- bumped eudev to 1.3.
Changes v1 -> v2:
- split patch for better readability.
- promoted init system selection above /dev management in "System
Configuration" menu.
- /dev management selection is not displayed if systemd is chosen as init
system, as udev is the only possible choice (suggested by Arnout).
- added "Dynamic with eudev" choice in /dev management selection.
- less patches for systemd/uclibc compatibility, thanks to recent update of
uclibc 0.9.33.2.
- autoreconf not needed anymore for systemd (thanks to removal of
configure.ac patch).
- ACL/Gudev support in systemd activated only if acl/libglib2 are
selected (suggested by Arnout).
- udev package provides BR2_PACKAGE_HAS_UDEV (suggested by Thomas).
- converted packages depending on
BR2_PACKAGE_UDEV/BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV to
BR2_PACKAGE_HAS_UDEV.
- eudev source code fetched as a tarball, not from Git tree (suggested by
Arnout).
- removed "enable all extras" option from eudev configuration: Gudev support
is activated if libglib2 is selected (suggested by Arnout).
- added option to build udev rule generator in eudev, as it was in previous
version of udev.
- removed dependency on hwdata for systemd and eudev, as both embed their
own hardware database.
Best regards,
ELB

eudev is a userspace device management daemon. It is a standalone
version, independent from systemd. It is a fork maintained by Gentoo.
Features:
- No extra configuration options are available: Gudev is build if
libglib2 is selected.
- No dependency on hwdata as the package uses its own hardware
database (as does systemd).
eudev 1.3 is in sync with systemd v207.

This patch converts udev to a virtual package. For the moment, there is only
one provider for the udev features: eudev.
Packages meant to provide udev-like features must select the symbol
BR2_PACKAGE_HAS_UDEV.
Packages depending on BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV or
BR2_PACKAGE_UDEV have been converted to use the new symbol.

To: buildroot
This patch bumps systemd to v207 but also declares it as a provider for the
udev virtual package.
Starting with systemd 183, udev has been merged into
systemd. The udev daemon is now installed as /lib/systemd/systemd-udevd.
This means that /dev management using udev is only available if systemd
is chosen as init system.
When configuring systemd, the following options are available:
- activation of systemd-journal-gatewayd, to access the journal via
HTTP.
- activation of extra features like journal compression and sealing.
Support for uClibc has also been removed because:
- upstream has no interest in supporting uClibc.
- using a shrinked libc brings no advantage, given the size of all the
programs included in Systemd. So using glibc does not matter.

I don't see the mmu option on the main symbol, so either that or the comment dependencies are not correct..

Finally we should also line up all the udev comments, but this can be
done in a separate patch.

Does it make sense to adding a help option on a hidden option? Can the

Hi Eric,
I'm very happy with this patch series, it really cleans things up a lot.
I first had some reservations about how the choices were organised in the
menus, but after trying out a few things it turns out to work pretty well.
I do agree with the comments Thomas has made, though. However, I
wouldn't want to stop this series to go into 2014.02-rc1, so I propose
that Peter still merges it for the release and that these small things
are fixed in follow-up patches.
I have one more remark about the way the udev virtual package is
implemented. We found out for the opengl packages that there is a better
way to do it, something like:
udev/Config.in:
config BR2_PACKAGE_HAS_UDEV
bool
config BR2_PACKAGE_PROVIDES_UDEV
depends on BR2_PACKAGE_HAS_UDEV
string
udev/udev.mk:
UDEV_SRC =
UDEV_DEPENDENCIES = $(call qstrip,$(BR2_PACKAGE_PROVIDES_UDEV))
ifeq ($(UDEV_DEPENDENCIES),)
define UDEV_CONFIGURE_CMDS
echo "No Udev implementation selected. Configuration error."
exit 1
endef
endif
eudev/Config.in:
...
if BR2_PACKAGE_EUDEV
config BR2_PACKAGE_PROVIDES_UDEV
default "eudev"
endif
That moves all the provider logic to the provider itself, which for
instance makes it possible for BR2_EXTERNAL to provide an alternative
udev implementation (e.g. a different udev version, which could be _very_
relevant).
I repeat, though: this can be done as a follow-up patch.
Regards,
Arnout

Just for the record: my comments are indeed minor and I agree they
shouldn't block the integration of this series.
Some of them could even be handled by Peter while merging the patches,
or otherwise as follow-up patches in 2014.05.

That's what I did on first try. BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV was
selected. But I ended up facing a limit of kconfig: this boolean symbol is
used in a choice/endchoice ("/dev management"), which prevents its value from
being recalculated when it is selected from Config.in.legacy.
For example, if BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV=y in
test_udev_legacy_defconfig and we perform:
$ make test_udev_legacy_defconfig
output/.config will contain:
# BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV is not set
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_DEVTMPFS=y
The default choice is selected. I discussed this issue on IRC with Yann E.
Morin last evening, but there is no workaround... So I chose to remove the
automatic selection of the new symbol and add detailed instructions.

The end user using the menu will not see it, but I added it for the user who
sometimes looks at the sources, as a kind of comment. When ThomasP suggested
to convert udev as a virtual package, I looked at opengl.mk hoping to find
information but found none... Maybe it would be better to add a section on how
to add virtual package and how to use it in the manual.
Thanks for your review.
Best regards,
ELB

When removing BR2_PACKAGE_UDEV_ALL_EXTRAS, you should certainly
replace it by the
"select ..." statements done in the BR2_PACKAGE_UDEV_ALL_EXTRAS
symbol, ie: acl and libglib2 (if I understood correctly hwdata is no
longer needed).

I'm not sure a help message is very useful for a hidden symbol, but
anyway it does not hurt ;-)

Linux >= 3.0, really? IIRC systemd requires devtmpfs (available for a long
time), and cgroup which has been available since linux-2.6.36 (though the
patch to make them available on older kernel is easy to backport on older
kernel).

How does this play with kconfig?
Does not kconfig complain about some circular dependencies here, because
you have BR2_INIT_SYSTEMD selecting BR2_PACAKGE_SYSTEMD, while
BR2_PACKAGE_SYSTEMD depends on BR2_INIT_SYSTEMD?

Indeed. The explanation above (a shorter one, at least) should have been
part of the commit log.

I forgot to add 'depends on BR2_USE_MMU # fork()'. I will fix this.

In fact BR2_PACKAGE_DBUS_GLIB already selects BR2_PACKAGE_LIBGLIB2, so only
BR2_PACKAGE_ACL is needed. I will fix this.
Thanks for your review.

I set the restriction to "Linux >= 3.0" as it is the one mentioned in the
README file of systemd. Linux 3.0 introduced the cgroup.procs file, needed by
systemd v207.
What should the help menu contain? Should it be only the minimum version
required with its reason, or the full list of features needed?
The README file contains a list of the kernel configuration options that are
needed to run systemd:
- CONFIG_DEVTMPFS
- CONFIG_CGROUPS
- CONFIG_INOTIFY_USER
- CONFIG_SIGNALFD
- CONFIG_TIMERFD
- CONFIG_EPOLL
- CONFIG_NET
- CONFIG_SYSFS
- CONFIG_PROC_FS
- CONFIG_FHANDLE
Others are strongly recommended:
- CONFIG_IPV6
- CONFIG_AUTOFS4_FS
- CONFIG_TMPFS_POSIX_ACL
- CONFIG_TMPFS_XATTR
- CONFIG_SECCOMP
The LINUX_CONFIGURE_CMDS in linux/linux.mk forces some kernel options for some
packages. Should I add all the ones previously listed for systemd?
I'm in favor of setting the help text to:
Systemd requires a Linux kernel >= 3.0.
The following features will be enabled in the Linux kernel:
devtmpfs, cgroups, [...]
So the end user is informed and will have a working configuration out of the
box.

I do not get any error from kconfig. I used the same trick to hide the
systemv package when 'SysV' is not chosen as init system. I do not know if it
is a bug or a feature of kconfig :)

Yes, the word 'provides' is more explicit. I'll put this in a follow-up patch.
If this is the definitive way of implementing a virtual package, shouldn't it
be added to docs/manual/adding-packages-tips.txt?
Thanks for the review.

Anyway, Buildroot only offers linux >=3.12, and 3.0 is old enough to
keep it like this. ;)

Indeed, you can look at the help message for lttng-modules for example
(having the actual symbol name may be good imho).
BTW, to be consistent, imho, we should automatically enable all the
mandatory kernel options (like Buildroot already does for a couple of
them).

If no bug is trigger, it's nice; otherwise... we'll report it to the
kconfig maintainer :P
