[NETFILTER]: xt_TCPMSS: don't allow netfilter --setmss to increase mss

When terminating DSL connections for an assortment of random customers, I've
found it necessary to use iptables to clamp the MSS used for connections to
work around the various ICMP blackholes in the greater net.  Unfortunately,
the current behaviour in Linux is imperfect and actually make things worse,
so I'm proposing the following: increasing the MSS in a packet can never be
a good thing, so make --set-mss only lower the MSS in a packet.

Yes, I am aware of --clamp-mss-to-pmtu, but it doesn't work for outgoing
connections from clients (ie web traffic), as it only looks at the PMTU on
the destination route, not the source of the packet (the DSL interfaces in
question have a 1442 byte MTU while the destination ethernet interface is
1500 -- there are problematic hosts which use a 1300 byte MTU).  Reworking
that is probably a good idea at some point, but it's more work than this is.

16 years ago[DCCP]: Introducing CCMPS
Gerrit Renker [Fri, 14 Dec 2007 01:37:55 +0000 (23:37 -0200)]
[DCCP]: Introducing CCMPS

This introduces a CCMPS field for setting a CCID-specific upper bound on the application payload
size, as is defined in RFC 4340, section 14.

Only the TX CCID is considered in setting this limit, since the RX CCID generates comparatively
small (DCCP-Ack) feedback packets. The CCMPS field includes network and transport layer header
lengths. The only current CCMPS customer is CCID4 (via RFC 4828).

A wrapper is used to allow querying the CCMPS even at times where the CCID modules may not have
been fully negotiated yet.

In dccp_sync_mss() the variable `mss_now' has been renamed into `cur_mps', to reflect that we are
dealing with an MPS, but not an MSS.
Since the DCCP code closely follows the TCP code, the identifiers `dccp_sync_mss' and
`dccps_mss_cache' have been kept, as they have direct TCP counterparts.

[CCID]: More informative registration

The patch makes the registration messages of CCID 2/3 a bit more
informative: instead of repeating the CCID number as currently done,

        "CCID: Registered CCID 2 (ccid2)"  or
        "CCID: Registered CCID 3 (ccid3)",

the descriptive names of the CCID's (from RFCs) are now used:

"CCID: Registered CCID 2 (TCP-like)" and
"CCID: Registered CCID 3 (TCP-Friendly Rate Control)".

To allow spaces in the name, the slab name string has been changed to
refer to the numeric CCID identifier, using the same format as before.

[IPV6] sit: Rebinding of SIT tunnels to other interfaces

This is similar to the change already done for IPIP tunnels.

Once created, a SIT tunnel can't be bound to another device.
To reproduce:

# create a tunnel:
ip tunnel add tunneltest0 mode sit remote 10.0.0.1 dev eth0
# try to change the bounding device from eth0 to eth1:

tunneltest0: ipv6/ip  remote 10.0.0.1  local any  dev eth0  ttl inherit

Notice the bound device has not changed from eth0 to eth1.

This patch fixes it. When changing the binding, it also recalculates the
MTU according to the new bound device's MTU.
