Subject: [Patch net-next v2 0/3] net: forbid net devices named "all" "default" or "config"
Date: Fri, 25 Jul 2014 15:25:07 -0700 [thread overview]
Message-ID: <1406327110-17227-1-git-send-email-xiyou.wangcong@gmail.com> (raw)
/proc/sys/net/ipv[46]/conf/<dev> could conflict with
/proc/sys/net/ipv[46]/conf/(all|default). And /proc/net/vlan/<dev>
could conflict with /proc/net/vlan/config. Besides kernel warnings,
undefined behavior such as duplicated proc files also appears, therefore
we should forbid these names.
v2: introduce a helper function, suggested by Florian
fix error handling for ipv6_add_dev() in addrconf_init()
Cong Wang (3):
ipv4: fail early when creating netdev named all or default
ipv6: fail early when creating netdev named all or default
vlan: fail early when creating netdev named config
