[Bug 214962] New: buggy udev persistent records created after calling of hostapd
https://bugzilla.novell.com/show_bug.cgi?id=214962 Summary: buggy udev persistent records created after calling of hostapd Product: SUSE Linux 10.1 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: sbrabec@novell.com QAContact: qa@suse.de Problem: After single starting of hostapd from hostap package, hostap network device is permanently renamed (i. e. name change persists after reboot) from wlan0 to wlan0ap. /etc/udev/rules.d/30-net_persistent_names.rules is updated and contains: # This rules are autogenerated from /lib/udev/rename_netiface. # But you can modify them, but make sure that you don't use an interface name # twice. Also add such interface name rules only in this rules file. Otherwise # rename_netiface will create wrong rules for new interfaces. # It is safe to delete a rule, as long as you did not disable automatic rule # generation. Only if all interfaces get a rule the renaming will work # flawlessly. See also /etc/udev/rules.d/31-net_create_names.rules. # # Read /usr/share/doc/packages/sysconfig/README.Persistent_Interface_Names for # further information. # # Use only a-z, A-Z and 0-9 for interface names! # SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:50:fc:33:ce:ba", IMPORT="/lib/udev/rename_netiface %k eth0" SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:60:b3:6b:d3:c5", IMPORT="/lib/udev/rename_netiface %k wlan0" SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:60:b3:6b:d3:c5", IMPORT="/lib/udev/rename_netiface %k wlan0ap" SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:60:b3:6b:d3:c5", IMPORT="/lib/udev/rename_netiface %k wlan0apap" -- 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, or are watching someone who is.

But as I wrote, it was started once and never more. There is a different problem: hostapd (correctly) created wlan0ap in addition to wlan0 (and later maybe incorrectly created wlan0apap in addition to wlan0ap). But both these devices have the same MAC and the persistent device naming scripts did a bad thing. -- 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, or are watching someone who is.

I am not sure, whether it is correct. It should prevent renaming of wlan0 to wlan0ap. hostapd creates wlan0ap with the same MAC, but a different function, in addition to wlan0. The code should prevent renaming of wlan0 to wlan0ap on reboot (and later renaming of wlan0ap to wlan0apap). -- 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, or are watching someone who is.
