Subject: [PATCH][IPV4] Swap the ifa allocation with the"ipv4_devconf_setall" call
Date: Fri, 07 Dec 2007 12:22:57 +0300 [thread overview]
Message-ID: <475910F1.1010007@openvz.org> (raw)
According to Herbert, the ipv4_devconf_setall should be called
only when the ifa is added to the device. However, failed
ifa allocation may bring things into inconsistent state.
Move the call to ipv4_devconf_setall after the ifa allocation.
Fits both net-2.6 (with offsets) and net-2.6.25 (cleanly).
