Description Russell King 2006-03-30 04:22:11 UTC

Most recent kernel where this bug did not occur: 2.6.16ish
Distribution:
Hardware Environment:
Software Environment:
Building an ARM kernel using h7201_defconfig configuration

Problem Description:

  LD      .tmp_vmlinux1
kernel/built-in.o:(.data+0xd1c): undefined reference to `uevent_helper'
make: *** [.tmp_vmlinux1] Error 1
make: Leaving directory `/var/tmp/kernel-orig'

Steps to reproduce:
Compile a kernel with CONFIG_HOTPLUG but without CONFIG_NET

Comment 1 Russell King 2006-03-30 04:28:38 UTC

Still present in 2.6.16-git18.  From my message on LKML:

which seems to be a reference from sysfs.c for ...proc.../sys/kernel/hotplug.
                                                                                
This brings up an interesting point - if CONFIG_NET is not set and
CONFIG_HOTPLUG is set, don't we want to call /sbin/hotplug?  If
...proc.../sys/kernel/hotplug isn't present then what?

allow CONFIG_NET=n

Michael, does this work for you?

Comment 3 Greg Kroah-Hartman 2006-05-08 14:59:26 UTC

This is now fixed in Linus's tree.

Comment 4 Russell King 2006-06-05 08:42:07 UTC

Confirmed as fixed.
