Subject: [PATCH] devinet: show all addresses assigned to interface
Date: Thu, 6 Sep 2007 16:10:00 +0100 [thread overview]
Message-ID: <20070906161000.74923fff@oldman> (raw)
Bug: http://bugzilla.kernel.org/show_bug.cgi?id=8876
Not all ips are shown by "ip addr show" command when IPs number assigned to an
interface is more than 60-80 (in fact it depends on broadcast/label etc
presence on each address).
Steps to reproduce:
It's terribly simple to reproduce:
# for i in $(seq 1 100); do ip ad add 10.0.$i.1/24 dev eth10 ; done
# ip addr show
this will _not_ show all IPs.
Looks like the problem is in netlink/ipv4 message processing.
This is fix from bug submitter, it looks correct.
