Package: udev
Version: 0.091-1
Severity: important
Hi,
on one of my boxes, I use bridge-utils and (previously) nameif to enslave an
ethernet device named "lan" (and some tap devices named "vpn") to a bridge
interface "br0". There's also a not-enslaved ethernet device named "modem"
The rules that were initially generated in z25_persistent-net.rules were:
ACTION=="add", SUBSYSTEM=="net", SYSFS{address}=="00:11:22:33:44:55",
NAME="eth0"
ACTION=="add", SUBSYSTEM=="net", SYSFS{address}=="ff:11:22:33:44:55",
NAME="eth1"
(it would've been nice to know, that the naming functionality would conflict
with nameif before I rebooted this headless box; Me using nameif gave me a false
sense of security)
I quickly changed eth0 and eth1 to "lan" and "modem" resp. - no problem there.
However, the problem is that the bridge "br0" has the same MAC address as "lan",
so the first persistent rule matched "br0" too. It tried to rename "br0" to
"lan" too, but as the name "lan" was already taken, it left it at "br0_temp".
udevinfo -a -p /sys/class/net/br0 gives me:
looking at device '/class/net/br0':
KERNEL=="br0"
SUBSYSTEM=="net"
SYSFS{weight}=="0"
SYSFS{tx_queue_len}=="0"
SYSFS{flags}=="0x1003"
SYSFS{mtu}=="1500"
SYSFS{carrier}=="1"
SYSFS{broadcast}=="ff:ff:ff:ff:ff:ff"
SYSFS{address}=="00:11:22:33:44:55"
SYSFS{type}=="1"
SYSFS{features}=="0x1000"
SYSFS{ifindex}=="6"
SYSFS{iflink}=="6"
SYSFS{addr_len}=="6"
Not exactly a lot to work with...
udevinfo -a -p /sys/class/net/lan gives me:
looking at device '/class/net/lan':
KERNEL=="lan"
SUBSYSTEM=="net"
SYSFS{weight}=="64"
SYSFS{tx_queue_len}=="1000"
SYSFS{flags}=="0x1103"
SYSFS{mtu}=="1500"
SYSFS{carrier}=="1"
SYSFS{broadcast}=="ff:ff:ff:ff:ff:ff"
SYSFS{address}=="00:11:22:33:44:55"
SYSFS{type}=="1"
SYSFS{features}=="0x1003"
SYSFS{ifindex}=="2"
SYSFS{iflink}=="2"
SYSFS{addr_len}=="6"
looking at device '/devices/pci0000:00/0000:00:09.0':
ID=="0000:00:09.0"
BUS=="pci"
DRIVER=="skge"
SYSFS{modalias}=="pci:v000011ABd00004320sv000010B8sd0000B452bc02sc00i00"
SYSFS{local_cpus}=="1"
SYSFS{irq}=="177"
SYSFS{class}=="0x020000"
SYSFS{subsystem_device}=="0xb452"
SYSFS{subsystem_vendor}=="0x10b8"
SYSFS{device}=="0x4320"
SYSFS{vendor}=="0x11ab"
looking at device '/devices/pci0000:00':
ID=="pci0000:00"
BUS==""
DRIVER==""
I ended up changing the generated rules into the following:
ACTION=="add", SUBSYSTEM=="net", SYSFS{address}=="00:11:22:33:44:55",
DRIVER=="skge", NAME="lan"
ACTION=="add", SUBSYSTEM=="net", SYSFS{address}=="ff:11:22:33:44:55",
DRIVER=="via-rhine", NAME="modem"
This isn't ideal because the driver may change names with successive kernel
upgrades ("sk98lin" -> "skge") but it works for now. It would be nice if the
rules were specific enough to avoid this conflict with bridges.
btw: I marked this as important, because it locked me out of my (remote,
headless) box, twice ;-).
In any case, thanks,
