Description:
If you plug in an Ethernet cable to a system running ifplugd and netcfg, and the `/etc/ifplugd/netcfg.action eth0 up`—that ifplugd runs on cable insertion—fails, then ifplugd is stuck in a mostly non-responsive state in which it does not respond to future unplugs and cable insertions. Note: I described this issue using 'eth0', but everything in my system is configured for 'lan0'. Steps to reproduce: 1.) Have all netcfg profiles down/off with ifplugd running via net-auto-wired and the Ethernet cable unplugged 2.) In a ethernet-dhcp netcfg profile, set DHCP_TIMEOUT to a small value (e.g. '1') 3.) Plug in the Ethernet cable, and notice that ifplugd will attempt to get a DHCP lease and promptly fail 4.) Unplug the Ethernet cable, wait a few seconds, then plug it back in. 5.) At this point, I would expect ifplugd to start the ethernet-dhcp netcfg profile and try it again, but /var/log/messages shows that ifplugd doesn't do anything at this point. 6.) The only way to recover from this is to manually run `netcfg ethernet-dhcp start` Additional info: * package version(s): ifplugd-0.28-11 netcfg-2.8.8-1 dhcpcd-5.5.6-1 initscripts-2012.06.3-2 * config and/or log files etc. In /etc/ifplugd/ifplugd.conf, only the following two lines are uncommented: NET_IFS="lan0" ARGS="-fwI -u0 -d10" Here is the netcfg profile that I'm having issues with: CONNECTION='ethernet' DESCRIPTION='A DHCP Ethernet connection using iproute' INTERFACE='lan0' IP='dhcp' DHCP_TIMEOUT=90 AUTO_WIRED=1 In /etc/rc.conf, I background the start of net-auto-wired. I also don't have any values set for a static IP address, etc. in /etc/rc.conf Below is the relevant part of /var/log/messages. I have annotated parts of it to indicate which "steps to reproduce" item is happening when. Note that `netcfg current` showed that no profiles were running every time it's shown in the logs here. <<Steps to reproduce #1-3>> 2012-07-26T18:09:42.328626-04:00 hostname kernel: [ 4878.491041] r8169 0000:04:00.0: lan0: link up 2012-07-26T18:09:42.328650-04:00 hostname kernel: [ 4878.491777] ADDRCONF(NETDEV_CHANGE): lan0: link becomes ready 2012-07-26T18:09:43.250044-04:00 hostname ifplugd(lan0)[481]: Link beat detected. 2012-07-26T18:09:44.351292-04:00 hostname ifplugd(lan0)[481]: Executing '/etc/ifplugd/netcfg.action lan0 up'. 2012-07-26T18:09:44.366672-04:00 hostname ifplugd(lan0)[481]: client: up 2012-07-26T18:09:44.378839-04:00 hostname ifplugd(lan0)[481]: client: loading wl-apt 2012-07-26T18:09:44.380898-04:00 hostname ifplugd(lan0)[481]: client: loading ethernet-dhcp 2012-07-26T18:09:44.382963-04:00 hostname ifplugd(lan0)[481]: client: loading wl-home 2012-07-26T18:09:44.407564-04:00 hostname dhcpcd[3998]: version 5.5.6 starting 2012-07-26T18:09:44.423193-04:00 hostname dhcpcd[3998]: lan0: sending IPv6 Router Solicitation 2012-07-26T18:09:44.423271-04:00 hostname dhcpcd[3998]: lan0: rebinding lease of 10.99.42.9 2012-07-26T18:09:48.424384-04:00 hostname dhcpcd[3998]: lan0: sending IPv6 Router Solicitation 2012-07-26T18:09:49.424485-04:00 hostname dhcpcd[3998]: timed out 2012-07-26T18:09:49.426026-04:00 hostname ifplugd(lan0)[481]: client: :: ethernet-dhcp up DHCP IP lease attempt failed. 2012-07-26T18:09:49.426858-04:00 hostname ifplugd(lan0)[481]: client: [fail] 2012-07-26T18:09:49.527788-04:00 hostname ifplugd(lan0)[481]: Program execution failed, return value is 1. 2012-07-26T18:09:54.974940-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:09:56.940912-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:10:01.812540-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current <<Steps to reproduce #4>> 2012-07-26T18:10:18.785362-04:00 hostname kernel: [ 4914.875006] r8169 0000:04:00.0: lan0: link down 2012-07-26T18:10:19.560300-04:00 hostname ifplugd(lan0)[481]: Link beat lost. 2012-07-26T18:10:23.548623-04:00 hostname kernel: [ 4919.629640] r8169 0000:04:00.0: lan0: link up 2012-07-26T18:10:23.664907-04:00 hostname ifplugd(lan0)[481]: Link beat detected. <<Steps to reproduce #5>> 2012-07-26T18:10:48.216983-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:10:56.206679-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:10:57.220360-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:10:57.774527-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current 2012-07-26T18:11:30.045798-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg current <<Steps to reproduce #6>> 2012-07-26T18:11:35.236003-04:00 hostname sudo: user : TTY=pts/1 ; PWD=/etc/ifplugd ; USER=root ; COMMAND=/usr/bin/netcfg ethernet-dhcp start 2012-07-26T18:11:35.343969-04:00 hostname dhcpcd[4519]: version 5.5.6 starting 2012-07-26T18:11:35.359410-04:00 hostname dhcpcd[4519]: lan0: sending IPv6 Router Solicitation |
