Distribution: no matter
Hardware Environment: generic i686
Software Environment: GNU
Problem Description:
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.
