https://bugzilla.novell.com/show_bug.cgi?id=383320 Summary: udev creates wrong persistent net rules for wlan interfaces Product: openSUSE 11.0 Version: Beta 1 Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: kasievers@novell.com ReportedBy: cstender@novell.com QAContact: qa@suse.de CC: dkukawka@novell.com, hschaa@novell.com Found By: --- After a fresh beta1 installation the persistent-net-rules file does not contain the ATTR{type}=="1". Without the attribute udev tries to rename wmaster0 to wlan0 while booting. This fails (because wlan0 is already there) and blocks the boot process for 30seconds. /etc/udev/rules.d/70-persistent-net.rules SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:19:d2:06:b5:2c", KERNEL=="wlan*", NAME="wlan0" If I delete the wrong line in 70-persistent-net.rules and reload the iwl3945 module, udev creates the following new rule: # PCI device 0x8086:0x4227 (iwl3945) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:19:d2:06:b5:2c", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0" -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I do not see any reason for yast to rewrite udev's rules in that case. Yast can "edit" the file, as long as "edit" means nothing else than changing the NAME= key. No, there is no facility to compose rules outside of udev. We already needed to change the rule creation logic several times, and will probably need to continue to do so, because of new hardware, buses, which do weird things, we need to work around. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I rewrited all that code but have some problems with udev: - there is no "udevtest" tool anymore

It is a debugging tool, it may change its output any time. Newer udev versions have only a single binary, which can be called as: /sbin/udevadm test <devpath> But still, do not use it in any software, it's output is not stable in any sense.

...

- udev rules matches only by MAC address, no BusID (in 10.3 I used KERNELS for that) - when I change NAME value, it's ignored and created new rule

If NAME= is set in any earlier rule, the udev persistent net generator should ignore the network interface completely. I guess yast should create and maintain its own rules file, which comes before 70-persistent-net.rules, instead of patching the udev maintained one. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't think we can change it for 11.0 (too late). Why there is comment "You can modify it, as long as you keep each rule on a single line." But yast code is now much better, it keeps all and change only needed options (ATTR{address}, KERNELS and NAME) There is only one issue - how to "match by BusID" instead of MAC address? This was probably changed from 10.3 (it works with KERNELS rule) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It should still work the same way, if the rule still matches and sets NAME=. There is was no change regarding matching parent device properties. But it's tricky, as there is hardware out, where the same device offers multiple interfaces with the same type. On such boxes, it might not work as expected without figuring out how to distinguish them properly. That's why we are adding all these keys with the new udev rules now. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
