ifplugd: if SIOCSIFFLAGS fails with EADDRNOTAVAIL, don't die
When using ifplugd on a RNDIS interface with monitor mode, using
SIOCSIFFLAGS seems to fail with EADDRNOTAVAIL. Treat it the same
as if iface disappeared again.
This has been observed on a Tegra TK1 using Linux 4.14. There seem
to be a race when the kernel is creating the device:
ifplugd(usb0): started: BusyBox v1.24.1 (2018-03-27 09:47:48 CEST)
ifplugd(usb0): interface doesn't exist, waiting
ifplugd(usb0): interface appeared
ifplugd(usb0): upping interface
ifplugd(usb0): setting interface flags failed: Cannot assign requested address
<exit>
With this patch ifplugd is successful in upping the device the second
time around:
ifplugd(usb0): upping interface
ifplugd(usb0): using SIOCETHTOOL detection mode
ifplugd(usb0): interface appeared
ifplugd(usb0): upping interface
ifplugd(usb0): setting interface flags failed: Cannot assign requested address
ifplugd(usb0): interface appeared
ifplugd(usb0): upping interface
ifplugd(usb0): using SIOCETHTOOL detection mode
ifplugd(usb0): link is up
ifplugd(usb0): executing '/etc/ifplugd/ifplugd.usb.action usb0 up'
ifplugd up
ifplugd(usb0): exit code: 0
