This implementation can deal with having many inetpeer roots, which is
a necessary prerequisite for per-FIB table rooted peer tables.
Each family (AF_INET, AF_INET6) has a sequence number which we bump
when we get a family invalidation request.
Each peer lookup cheaply checks whether the flush sequence of the
root we are using is out of date, and if so flushes it and updates
the sequence number.

There is zero point to this function.
It's only real substance is to perform an extremely outdated BSD4.2
ICMP check, which we can safely remove. If you really have a MTU
limited link being routed by a BSD4.2 derived system, here's a nickel
go buy yourself a real router.
The other actions of ip_rt_frag_needed(), checking and conditionally
updating the peer, are done by the per-protocol handlers of the ICMP
event.
TCP, UDP, et al. have a handler which will receive this event and
transmit it back into the associated route via dst_ops->update_pmtu().
This simplification is important, because it eliminates the one place
where we do not have a proper route context in which to make an
inetpeer lookup.

We encode the pointer(s) into an unsigned long with one state bit.
The state bit is used so we can store the inetpeer tree root to use
when resolving the peer later.
Later the peer roots will be per-FIB table, and this change works to
facilitate that.

Since it's guarenteed that we will access the inetpeer if we're trying
to do timewait recycling and TCP options were enabled on the
connection, just cache the peer in the timewait socket.
In the future, inetpeer lookups will be context dependent (per routing
realm), and this helps facilitate that as well.
Signed-off-by: David S. Miller <davem@davemloft.net>
The get_peer method TCP uses is full of special cases that make no
sense accommodating, and it also gets in the way of doing more
reasonable things here.
First of all, if the socket doesn't have a usable cached route, there
is no sense in trying to optimize timewait recycling.
Likewise for the case where we have IP options, such as SRR enabled,
that make the IP header destination address (and thus the destination
address of the route key) differ from that of the connection's
destination address.
Just return a NULL peer in these cases, and thus we're also able to
get rid of the clumsy inetpeer release logic.

/proc/net/unix has quadratic behavior, and can hold unix_table_lock for
a while if high number of unix sockets are alive. (90 ms for 200k

We already have a hash table, so its quite easy to use it.

This patch also spreads unbound sockets to 256 hash slots, to speedup

When any interface goes down, it could be the one that we
were doing a remain-on-channel with. We therefore need to
cancel the remain-on-channel and flush the related work
structs so they don't run after the interface has been
removed or even destroyed.
It's also possible in this case that an off-channel SKB
was never transmitted, so free it if this is the case.
Note that this can also happen if the driver finishes
the off-channel period without ever starting it.

Mesh station that joins an MBSS is reachable using mesh portal with 6

MBSSes are bridged. However, if the mesh station later moves into the
same MBSS of those mesh stations, it is unreachable by mesh stations

is to perform mesh_path_lookup, if it is available for the target
destination, mpp_path_lookup is not performed. When the mesh station
moves back to its original MBSS, the mesh_paths will be deleted once
expired. So, it will be reachable using mpp_path_lookup again.
