Simon Arlott e0f43752a9 bridge: update sysfs link names if port device names have changed
Links for each port are created in sysfs using the device
name, but this could be changed after being added to the
bridge.

As well as being unable to remove interfaces after this
occurs (because userspace tools don't recognise the new
name, and the kernel won't recognise the old name), adding
another interface with the old name to the bridge will
cause an error trying to create the sysfs link.

This fixes the problem by listening for NETDEV_CHANGENAME
notifications and renaming the link.

stephen hemminger 28a16c9796 bridge: change console message interface
Use one set of macro's for all bridge messages.

Note: can't use netdev_XXX macro's because bridge is purely
virtual and has no device parent.

Joe Perches 736d58e3a2 netfilter: remove unnecessary returns from void function()s
This patch removes from net/ netfilter files
all the unnecessary return; statements that precede the
last closing brace of void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

This patch adds support for multiple independant multicast routing instances,

Userspace multicast routing daemons can bind to a specific table instance by

stored in the raw socket data and affects all following ip6mr setsockopt(),
getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT)
is created with a default routing rule pointing to it. Newly created pim6reg
devices have the table number appended ("pim6regX"), with the exception of
devices created in the default table, which are named just "pim6reg" for
compatibility reasons.

Packets are directed to a specific table instance using routing rules,
similar to how regular routing rules work. Currently iif, oif and mark
are supported as keys, source and destination addresses could be supported
additionally.

Example usage:

- bind pimd/xorp/... to a specific table:

uint32_t table = 123;
setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table));

- create routing rules directing packets to the new table:

# ip -6 mrule add iif eth0 lookup 123
# ip -6 mrule add oif eth0 lookup 123

Patrick McHardy b5aa30b191 ipv6: ip6mr: remove net pointer from struct mfc6_cache
Now that cache entries in unres_queue don't need to be distinguished by their
network namespace pointer anymore, we can remove it from struct mfc6_cache
add pass the namespace as function argument to the functions that need it.

Patrick McHardy c476efbcde ipv6: ip6mr: move unres_queue and timer to per-namespace data
The unres_queue is currently shared between all namespaces. Following patches
will additionally allow to create multiple multicast routing tables in each
namespace. Having a single shared queue for all these users seems to excessive,
move the queue and the cleanup timer to the per-namespace data to unshare it.

As a side-effect, this fixes a bug in the seq file iteration functions: the
first entry returned is always from the current namespace, entries returned
after that may belong to any namespace.

which will be required by the upcoming __rcu annotations.

The __nf_ct_l3proto_find() call doesn't actually need rcu read side
protection since the caller holds a reference to the protocol. Use
rcu_read_lock() anyways to avoid the warning.

Andreas Meissner bbd725435d IPv4: unresolved multicast route cleanup
Fixes the expiration timer for unresolved multicast route entries.
In case new multicast routing requests come in faster than the 
expiration timeout occurs (e.g. zap through multicast TV streams), the 
timer is prevented from being called at time for already existing entries.

As the single timer is resetted to default whenever a new entry is made, 
the timeout for existing unresolved entires are missed and/or not 
updated. As a consequence new requests are denied when the limit of 
unresolved entries has been reached because old entries live longer than 
they are supposed to.

The solution is to reset the timer only for the first unresolved entry 
in the multicast routing cache. All other timers are already set and 
updated correctly within the timer function itself by now.
