UDEV (eudev) update

[Oleg Vinichenko]

Funtoo restricting udev update for last ~2.5 years. It caused various issues with certain packages, numerous masks, package forks and version restrictions. Funtoo needs to update...to eudev, a special flavor of udev package by Gentoo. Why eudev? First of all, ebuild is better, eudev build system looks good and it's very latest udev code, predictable networking is disabled by default (using old fashioned, wlan*, eth*, ath*). Update will solve:
1. udev fixes itself
2. package restrictions, masked due newer udev requirement
3. hwdb, hardware vendors support, which is not working correct with old udev
4. lvm2 udev USE flag build issue
5. much better desktop support

Ebuilds added to tree. Tested locally, works fine. Following steps required to test:

emerge --sync

add to /etc/portage/package.unmask

>=virtual/udev-208

>=sys-fs/eudev-1.4

>=sys-apps/hwids-20140103

remove udev from world file:

emerge --deselect udev

Update eudev and friends:

emerge -u virtual/udev hwids

Reboot and report all possible issues. Main support is http://bugs.funtoo.org/browse/FL-986 , here and on IRC #funtoo.

Best regards, Oleg.

[Oleg Vinichenko]

sys-fs/lvm2 unmask and update required (if installed)
adding

>=sys-fs/lvm2-2.02.103 to /etc/portage/package.unmask

and emerge lvm2 should be sufficient for complete update

[Raphael Bastos]

Oleg,

How do I upgrade from mdev? I've migrated to mdev a few months. 

Congratulations for the excellent work!

Att,

your system is not affected then :) but if it causing any side-effects, please, report.

[Raphael Bastos]

Thanks Oleg. :D

I applied the procedure to a testing environment.

It'a a basic system with X and twm. Kernel is 3.13.0. No problem in rebooting into new environment.

Nota Bene : this environment will be used to migrate to systemd.

[Guy Fontaine]

I can't fully migrate to eudev-1.4 because of  @preserved-rebuild :

!!! existing preserved libs:

>>> package: sys-fs/lvm2-2.02.95-r2

 *  - /lib64/libdevmapper.so.1.02

 *      used by /opt/VirtualBox/VBoxVolInfo (app-emulation/virtualbox-bin-4.3.6)

 *      used by /usr/lib64/libcryptsetup.so.4.5.0 (sys-fs/cryptsetup-1.6.3)

>>> package: sys-fs/udev-171-r10

 *  - /lib64/libudev.so.0

 *  - /lib64/libudev.so.0.11.5

 *      used by /bin/findmnt (sys-apps/util-linux-2.23.2-r1)

 *      used by /bin/lsblk (sys-apps/util-linux-2.23.2-r1)

 *      used by /lib64/dhcpcd/dev/udev.so (net-misc/dhcpcd-6.2.0-r1)

 *      used by 13 other files

Also /etc/init.d/udev --nodeps restart doesn't work :

* Starting udev ...

 * start-stop-daemon: /sbin/udevd is already running

 * Failed to start udev

[Guy Fontaine]

About my previous message... that is the situation in my Funtoo MATE environment. I restored previous environment because I use it on an everyday basis.

Le vendredi 24 janvier 2014 00:05:08 UTC-5, Oleg a écrit :

[Oleg Vinichenko]

it is required to run revdep-rebuild and emerge @preserved-rebuild, because packages need to rebuild against newer libudev, this is reflected in above message. You don't need to run /etc/init.d/udev --nodeps restart, you need to reboot. Will remove unnecessary step from ebuild.

[Guy Fontaine]

@preserved-rebuild doesn't work because google-chrome-beta needed and this is hard masked because split into three parts by Gentoo.

I can't install eudev-1.4 being blocked by lvm2 required by VirtualBox. 

Those are reasons why I'm back to udev-171 which works fine anyway. I'll move to systemd instead.

2014/1/25 Oleg Vinichenko <ol...@funtoo.org>

[Oleg Vinichenko]

it is said to update lvm2 along with update, i don't understand why you skipping it?

[Oleg Vinichenko]

systemd is out of this announcement scope

[Oleg Vinichenko]

and there is no support reports in main page http://bugs.funtoo.org/browse/FL-986

[Guy Fontaine]

Oelg, you wrote that it works fine. What is your environment (desktop, Web browser, virtualization tool) ?

My desktop is MATE.

Web browser is www-client/google-chrome-32.0.1700.72_beta1:beta

Virtualization : app-emulation/virtualbox-bin-4.3.6:0

oleg, I think for him it is the block that is not working, as there is a block, so Guy, a simple unmask will do the trick for you

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "www-client/google-chrome:beta".

Package is in my /etc/portage/package.unmask folder but not found.

These are the steps I took to work around this block

# USE="-static" emerge -v1 lvm2
# emerge -u virtual/udev hwids

[Oleg Vinichenko]

that's not correct, simple unmask required and it worked for Guy

[Guy Fontaine]

I'm currently working on issue with google-chrome.... @preserved-rebuild running now. Back with solution when process over.

2014/1/25 Oleg Vinichenko <ol...@funtoo.org>

[Oleg Vinichenko]

this is not issue, this is requirement to rebuild packages against newer libudev version

[Guy Fontaine]

Oleg... I had to unmerge my installed version of beta google-chrome, because blocking @preserved-rebuild.

When 14 packages from @preserved-rebuild are rebuilt, I'll re-emerge google-chrome.

2014/1/25 Oleg Vinichenko <ol...@funtoo.org>

[Jean-Francis Roy]

Guy, google-chrome is a separate issue and has nothing to do with udev/eudev switch. You should fix existing issues on your system before attempting a switch like that, as you are accumulating problems :-) hehe

[Guy Fontaine]

JF... I know it is not directly related to eudev. I would have met with same issue just trying to update my system if @preserved-rebuild had have to be run. :-) 

2014/1/25 Jean-Francis Roy <jeanf...@funtoo.org>

[Guy Fontaine]

google-chrome issue resolved.... Not related to eudev but might happen if you haven't yet update google-chrome-beta.

Running @preserved-rebuild

# emerge --ask @preserved-rebuild

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "www-client/google-chrome:beta".

(dependency required by "@preserved-rebuild" [argument])

Unmerge google-chrome

# emerge --ask --unmerge google-chrome

Rerun @preserved-rebuild

# emerge --ask @preserved-rebuild

Emerge new google-chrome-beta

# emerge google-chrome-beta

Everything seems ok.

Time to reboot I think.

[Raphael Bastos]

Oleg,

After unmerge sys-fs/lvm2-2.02.97 eudev and sys-fs/lvm2-2.02.103 compile fine in my system.

I had already migrated udev to mdev previously. After compile eudev, my openvpn stop working. File /dev/tun not created after reboot. :(

[Oleg Vinichenko]

why do you messing with mdev/eudev? you have to use either one, and if you switched to eudev, you need to disable mdev from runlevels

[Guy Fontaine]

System rebooted... No third encounter for now :-P

2014-01-25 Oleg Vinichenko <ol...@funtoo.org>

[Raphael Bastos]

Oleg,

I had removed the mdev. Anyway, After eudev recompiled again, only the /etc/init.d/udev-postmount  was created. 

I also noticed that it does not create the /dev/fd, which is just a symlink to /proc/self/fd

[Oleg Vinichenko]

no issues with /dev/fd on my side, there should be automatic addition of udev-mount udev into sysinit runlevel and udev-postmount in default runlevel, please, check if you made something manually?

[Oleg Vinichenko]

even better paste output of rc-status sysinit and rc-status default

[Guy Fontaine]

That's what rc-update show | grep udev must return :

udev                        sysinit

udev-mount             sysinit

udev-postmount      boot default

2014-01-25 Oleg Vinichenko <ol...@funtoo.org>

[Oleg Vinichenko]

right, that's how it supposed to look.

[Raphael Bastos]

vm-jupiter ~ # grep udev /var/log/rc.log

 * Unable to find udev executable.

 * ERROR: udev failed to start

 * Starting udevd daemon ...

[Oleg Vinichenko]

something screwed on your box, could be fixed by emerge -1 eudev

[Guy Fontaine]

Raphael... did you run /etc/init.d/udev restart ? I did that and I got into a mess.

2014-01-25 Raphael Bastos <raphae...@hackstore.com.br>

[Oleg Vinichenko]

do not run any scripts manually, reboot required

[Raphael Bastos]

Thanks Oleg,

But not solve my problem to create /dev/tun :(

See:

vm-jupiter ~ # rc-update show | grep udev

                 udev |                       sysinit

           udev-mount |                       sysinit

       udev-postmount | boot default

            udev-save |              shutdown

vm-jupiter ~ # ps auxw|grep udev

root      1407  0.0  0.1  34104  1736 ?        Ss   17:54   0:00 /sbin/udevd --daemon

[Guy Fontaine]

I don't have udev-save. What's the reason ?

2014-01-25 Raphael Bastos <raphae...@hackstore.com.br>

[Oleg Vinichenko]

it's not needed (not used)

adding

and emerge lvm2 should be sufficient for complete update

I am using mdev + eudev and is running fine. : D

Guy,

I'm using eudev ebuild just to keep updated udev ebuilds dependent. 

The eudev alone did not create TUN devices, and not needed for VPN also creates new devices such as flash drive or external hd. 

I reported this a few days ago.

Raphael,

Thus mdev + eudev  + openrc sound like recommended combination. Can we think of an alternative to systemd ?

2014-01-31 Raphael Bastos <raphae...@hackstore.com.br>:

[Raphael Bastos]

Guy,

OpenRC + mdev + eudev = perfect! \o/

In my opinion not recommend systemd on servers since it is not yet ready. Try running the command HALT and then tell me what happens using systemd. kkkkkkkkkkkkkkkkkk

I'm using systemd in openSUSE 13.1 and am really enjoying this version. 

It may be that from May or June be able to test systemd in Funtoo. 

It is a great idea since numerous companies and distros are adopting it. CentOS, Fedora, RedHat and SUSE and OpenSUSE are already using the system in beta and stable at least 1 year.

Adam, you using ~arch, you should have glibc-2.18 on your box. This version has correct statc link detection and should be sufficient to update lvm2/eudev

[Adam Smith]

That is what I get for not updating for awhile. All is good now

Thank you

[Jonathan Vasquez]

1. package.unmask:

>=virtual/udev-208

>=sys-fs/eudev-1.4

>=sys-apps/hwids-20140103

=sys-fs/lvm2-2.02.103

=sys-fs/cryptsetup-1.6.4

 

2. emerge --deselect udev

(at this point even if lvm2/cryptsetup were unmasked, there were still lvm2/cryptsetup blocks, so I unmerged lvm2/cryptsetup temporarily, updated udev, and merged lvm2/cryptsetup later.

I havent tried this but doing an explicit install as oleg said probably will work: emerge -au lvm2/cryptsetup)

 

3. unmerge lvm2/cryptsetup

4. emerge -u virtual/udev hwids

5. remove udev-postmount from 'boot' service since there are two udev-postmounts (one that was probably from old udev, and eudev adds another one to default)

6. merge lvm2/cryptsetup

7. emerge --depclean

8. preserved-rebuild stuff for new eudev

9. then I removed 'lvm' and 'device-mapper' from 'boot' runlevel since I dont need them

other:

 

is it good if 'virtual/udev' gets added to world? would it be better to not have udev in world and 1 shot it? if anything udev should be part of @system

[Jonathan Vasquez]

Everything worked btw.. the previous post was the steps I took to get it working.
