net: rtnetlink: decouple rtnetlink address families from real address families

2010-04-26T14:13:54+00:00

Decouple rtnetlink address families from real address families in socket.h to
be able to add rtnetlink interfaces to code that is not a real address family
without increasing AF_MAX/NPROTO.

This will be used to add support for multicast route dumping from all tables
as the proc interface can't be extended to support anything but the main table
without breaking compatibility.

This partialy undoes the patch to introduce independant families for routing
rules and converts ipmr routing rules to a new rtnetlink family. Similar to
that patch, values up to 127 are reserved for real address families, values
above that may be used arbitrarily.

net: fib_rules: mark arguments to fib_rules_register const and __net_initdata

2010-04-26T14:02:04+00:00

fib_rules_register() duplicates the template passed to it without modification,
mark the argument as const. Additionally the templates are only needed when
instantiating a new namespace, so mark them as __net_initdata, which means
they can be discarded when CONFIG_NET_NS=n.

net: fib_rules: decouple address families from real address families

2010-04-13T21:49:31+00:00

Decouple the address family values used for fib_rules from the real
address families in socket.h. This allows to use fib_rules for
code that is not a real address family without increasing AF_MAX/NPROTO.

Values up to 127 are reserved for real address families and map directly
to the corresponding AF value, values starting from 128 are for other
uses. rtnetlink is changed to invoke the AF_UNSPEC dumpit/doit handlers
for these families.

net: fib_rules: set family in fib_rule_hdr centrally

2010-04-13T21:49:30+00:00

All fib_rules implementations need to set the family in their ->fill()
functions. Since the value is available to the generic fib_nl_fill_rule()
function, set it there.

net: fib_rules: consolidate IPv4 and DECnet ->default_pref() functions.

2010-04-13T21:49:30+00:00

Both functions are equivalent, consolidate them since a following patch
needs a third implementation for multicast routing.

net: Allow fib_rule_unregister to batch

2009-12-03T20:22:55+00:00

Refactor the code so fib_rules_register always takes a template instead
of the actual fib_rules_ops structure that will be used.  This is
required for network namespace support so 2 out of the 3 callers already
do this, it allows the error handling to be made common, and it allows
fib_rules_unregister to free the template for hte caller.

Modify fib_rules_unregister to use call_rcu instead of syncrhonize_rcu
to allw multiple namespaces to be cleaned up in the same rcu grace
period.

net: Remove unused parameter from fill method in fib_rules_ops.

2009-05-21T00:26:23+00:00

The netlink message header (struct nlmsghdr) is an unused parameter in
fill method of fib_rules_ops struct.  This patch removes this
parameter from this method and fixes the places where this method is
called.
