Subject: [PATCH] ipv6/addrconf: call ipv6_mc_up() for non-Ethernet interface
|
||||
MIME-Version: 1.0

||||
Content-Type: text/plain; charset=UTF-8

Rafał found an issue that for non-Ethernet interface, if we down and up
|
||||
frequently, the memory will be consumed slowly.
|
||||
|
||||
The reason is we add allnodes/allrouters addressed in multicast list in
|
||||
ipv6_add_dev(). When link down, we call ipv6_mc_down(), store all multicast
|
||||
addresses via mld_add_delrec(). But when link up, we don't call ipv6_mc_up()
|
||||
for non-Ethernet interface to remove the addresses. This makes idev->mc_tomb
|
||||
getting bigger and bigger. The call stack looks like:
|
||||
|
||||
addrconf_notify(NETDEV_REGISTER)
|
||||
ipv6_add_dev
|
||||
ipv6_dev_mc_inc(ff01::1)
|
||||
ipv6_dev_mc_inc(ff02::1)
|
||||
ipv6_dev_mc_inc(ff02::2)
|
||||
|
||||
addrconf_notify(NETDEV_UP)
|
||||
addrconf_dev_config
|
||||
/* Alas, we support only Ethernet autoconfiguration. */
|
||||
return;
|
||||
|
||||
addrconf_notify(NETDEV_DOWN)
|
||||
addrconf_ifdown
|
||||
ipv6_mc_down
|
||||
igmp6_group_dropped(ff02::2)
|
||||
mld_add_delrec(ff02::2)
|
||||
igmp6_group_dropped(ff02::1)
|
||||
igmp6_group_dropped(ff01::1)
|
||||
|
||||
After investigating, I can't found a rule to disable multicast on
|
||||
non-Ethernet interface. In RFC2460, the link could be Ethernet, PPP, ATM,
|
||||
tunnels, etc. In IPv4, it doesn't check the dev type when calls ip_mc_up()
|
||||
in inetdev_event(). Even for IPv6, we don't check the dev type and call
|
||||
ipv6_add_dev(), ipv6_dev_mc_inc() after register device.
|
||||
|
||||
So I think it's OK to fix this memory consumer by calling ipv6_mc_up() for
|
||||
non-Ethernet interface.
|
||||
|
||||
v2: Also check IFF_MULTICAST flag to make sure the interface supports
|
||||
multicast
