Hi, with sys-fs/udev-222 I notice the following messages in `dmesg` after boot: > [ 2.491212] vmxnet3 0000:03:00.0 lan0: renamed from eth1 > [ 2.491781] input: PC Speaker as /devices/platform/pcspkr/input/input4 > [ 2.494727] input: ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input5 > [ 2.502750] udevd[2389]: Process 'net.sh eth0 start' failed with exit code 1. > [ 2.505802] udevd[2385]: Process 'net.sh eth1 start' failed with exit code 1. I haven't seen this with sys-fs/udev-220-r3 so I run bisect and found the following "bad commit": > e013d21b6218011c99dbbcd4c61fc73a24490a94 is the first bad commit > commit e013d21b6218011c99dbbcd4c61fc73a24490a94 > Author: Filipe Brandenburger <filbranden@google.com> > Date: Wed Jun 3 07:31:12 2015 -0700 > > build-sys: Work around --with-rootprefix= (empty) not producing / > > Since we introduced AX_NORMALIZE_PATH, using --with-rootprefix=/ does > produce an empty string, but using --with-rootprefix= (empty) now > produces "." instead which is wrong. > > Work around it until we can find a better solution for AX_NORMALIZE_PATH > upstream at autoconf-archive. > > Bug: https://github.com/systemd/systemd/issues/54 https://github.com/systemd/systemd/commit/e013d21b6218011c99dbbcd4c61fc73a24490a94 When I revert this commit I don't see the quoted message anymore in sys-fs/udev-222. net.sh will be called from "/lib/udev/rules.d/90-network.rules". I have the feeling that this rule didn't work in the last udev versions in Gentoo. Now, due to the commit, this rule will be called again and uncovers a different problem. Things to note: - My system has 2 NICs - I am renaming one of my NICs via $ cat /etc/udev/rules.d/80-net-setup-link.rules SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:0c:29:45:a5:fd", NAME="lan0" - Please notice that udeved renamed the NIC at 2.491212 but tries to to start net.sh using the *old* name (eth1 at 2.505802). That sounds like a bug in udev. Not? Reproducible: Always
I think this is a bug in the netifrc udev rule. # Activate our network if we can SUBSYSTEM=="net", ACTION=="add", RUN+="net.sh %k start" SUBSYSTEM=="net", ACTION=="remove", RUN+="net.sh %k stop" From the udev manual: The NAME, SYMLINK, PROGRAM, OWNER, GROUP, MODE, and RUN fields support simple string substitutions. The RUN substitutions are performed after all rules have been processed, right before the program is executed, allowing for the use of device properties set by earlier matching rules. For all other fields, substitutions are performed while the individual rule is being processed. The available substitutions are: $kernel, %k The kernel name for this device. $name The current name of the device. If not changed by a rule, it is the name of the kernel device. Does the udev rule work if you change %k to $name?
When I change %k to $name udev will use the correct names, yes. But net.sh is still failing: > [ 2.358796] udevd[2326]: starting version 222 > [ 2.552920] vmxnet3 0000:03:00.0 lan0: renamed from eth1 > [ 2.557910] udevd[2455]: Process 'net.sh eth0 start' failed with exit code 1. > [ 2.562306] input: PC Speaker as /devices/platform/pcspkr/input/input4 > [ 2.567088] input: ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input5 > [ 2.568554] udevd[2457]: Process 'net.sh lan0 start' failed with exit code 1. And it is "/etc/init.d/net.eth0" and "/etc/init.d/net.lan0" which is failing with exit code 1: > * net.eth0: not allowed to be hotplugged > * net.lan0: not allowed to be hotplugged
As expected, when I set 'rc_hotplug="*"' in "/etc/rc.conf" the error goes away but I don't want to enable hotplug for my built-in network cards (especially because this would start net.eth0 which I haven't enabled in my runlevels). Seems like net.sh is missing a check if hotplug is enabled or not for the interface. I tried to use the service_hotplugged applet but I don't know how to get it working. This is how openrc-run checks if hotplugging is allowed: https://github.com/OpenRC/openrc/blob/master/src/rc/openrc-run.c#L1027-L1057
Updating summary and copying openrc.
What is your rc_hotplug set to normally? an rc_hotplug="* !net.eth*" should work to exclude your eth0 etc while letting net.lan0 launch.
Default value, rc_hotplug is not set.
So is the issue here -just- the failure message in dmesg?? because if it's acting the way it should, which is to not start the init script during hotplug, and the exit code 1 isn't causing anything else to fail, then it looks to me like everything is fine.
Yes, you are right: Currently it is just a failure message from udev. No "real" problem (at least I haven't seen any problems due to these messages).
A similar issue at https://github.com/systemd/systemd/issues/1070 but it does matter for me. I have to startup the USB dongle modem via /etc/init.d/net.ppp0 which uses the /dev/ttyUSB0 interface. It does not receive DHCP answer via wwp0s29u1u2i1 interface (originally wwan0). # emerge --info Portage 2.2.18 (python 2.7.9-final-0, default/linux/amd64/13.0, gcc-4.9.3, glibc-2.21-r1, 4.1.6-default-pciehp x86_64) ================================================================= System uname: Linux-4.1.6-default-pciehp-x86_64-Intel-R-_Core-TM-_i7-2640M_CPU_@_2.80GHz-with-gentoo-2.2 KiB Mem: 16361268 total, 14947272 free KiB Swap: 16776188 total, 16776188 free Timestamp of repository gentoo: Mon, 24 Aug 2015 13:00:01 +0000 sh bash 4.3_p42 ld GNU ld (Gentoo 2.25.1 p1.0) 2.25.1 app-shells/bash: 4.3_p42::gentoo dev-java/java-config: 2.2.0::gentoo dev-lang/perl: 5.20.2::gentoo dev-lang/python: 2.7.9-r2::gentoo, 3.2.5-r6::gentoo, 3.4.3::gentoo dev-util/cmake: 3.2.1::gentoo dev-util/pkgconfig: 0.28-r2::gentoo sys-apps/baselayout: 2.2::gentoo sys-apps/openrc: 0.17::gentoo sys-apps/sandbox: 2.6-r1::gentoo sys-devel/autoconf: 2.13::gentoo, 2.69-r1::gentoo sys-devel/automake: 1.11.6-r1::gentoo, 1.12.6::gentoo, 1.13.4::gentoo, 1.14::gentoo, 1.15::gentoo sys-devel/binutils: 2.25.1::gentoo sys-devel/gcc: 4.3.6-r1::gentoo, 4.4.7::gentoo, 4.6.4::gentoo, 4.7.4::gentoo, 4.8.4::gentoo, 4.9.3::gentoo sys-devel/gcc-config: 1.8::gentoo sys-devel/libtool: 2.4.6-r1::gentoo sys-devel/make: 4.1-r1::gentoo sys-kernel/linux-headers: 4.0::gentoo (virtual/os-headers) sys-libs/glibc: 2.21-r1::gentoo Repositories: gentoo location: /usr/portage sync-type: rsync sync-uri: rsync://rsync.gentoo.org/gentoo-portage priority: -1000 ...

Apparently the only reason my networking is still working at all is that some runlevel-enabled service is auto-starting the "dhcpcd" service (presumably because it needs "net", and "net.lo" no longer provides "net"). My "net.enp3s0" service is actually stopped, though the interface is up and bound (presumably by "dhcpcd"). So hotplugging of "predictably named" network interfaces appears broken.

I hit this bug (that net.x service hotplugging does not work with renamed interface). Changing "%k" to "$name" in /lib/udev/rules.d/90-network.rules fixed this. Will this issue be tracked in this bug report or should new one be created?
