Ulrich Weber 45bb006090 ipv6: Remove IPV6_ADDR_RESERVED
RFC 4291 section 2.4 states that all uncategorized addresses
should be considered as Global Unicast.

This will remove IPV6_ADDR_RESERVED completely
and return IPV6_ADDR_UNICAST in ipv6_addr_type() instead.

Patrick McHardy 5d0aa2ccd4 netfilter: nf_conntrack: add support for "conntrack zones"
Normally, each connection needs a unique identity. Conntrack zones allow
to specify a numerical zone using the CT target, connections in different
zones can use the same identity.

Example:

iptables -t raw -A PREROUTING -i veth0 -j CT --zone 1
iptables -t raw -A OUTPUT -o veth1 -j CT --zone 1

Patrick McHardy 8fa9ff6849 netfilter: fix crashes in bridge netfilter caused by fragment jumps
When fragments from bridge netfilter are passed to IPv4 or IPv6 conntrack
and a reassembly queue with the same fragment key already exists from
reassembling a similar packet received on a different device (f.i. with
multicasted fragments), the reassembled packet might continue on a different
codepath than where the head fragment originated. This can cause crashes
in bridge netfilter when a fragment received on a non-bridge device (and
thus with skb->nf_bridge == NULL) continues through the bridge netfilter
code.

Add a new reassembly identifier for packets originating from bridge
netfilter and use it to put those packets in insolated queues.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14805

Patrick McHardy 0b5ccb2ee2 ipv6: reassembly: use seperate reassembly queues for conntrack and local delivery
Currently the same reassembly queue might be used for packets reassembled
by conntrack in different positions in the stack (PREROUTING/LOCAL_OUT),
as well as local delivery. This can cause "packet jumps" when the fragment
completing a reassembled packet is queued from a different position in the
stack than the previous ones.

Add a "user" identifier to the reassembly queue key to seperate the queues
of each caller, similar to what we do for IPv4.

Al Viro eeb61f719c missing bits of net-namespace / sysctl
Piss-poor sysctl registration API strikes again, film at 11...

What we really need is _pathname_ required to be present in already
registered table, so that kernel could warn about bad order.  That's the
next target for sysctl stuff (and generally saner and more explicit
order of initialization of ipv[46] internals wouldn't hurt either).

For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and make sure
that sufficient skeleton is there before we start registering per-net
sysctls.

David S. Miller db8dac20d5 [UDP]: Revert udplite and code split.
This reverts commit db1ed684f6 ("[IPV6]
UDP: Rename IPv6 UDP files."), commit
8be8af8fa4 ("[IPV4] UDP: Move
IPv4-specific bits to other file.") and commit
e898d4db27 ("[UDP]: Allow users to
configure UDP-Lite.").

First, udplite is of such small cost, and it is a core protocol just
like TCP and normal UDP are.

We spent enormous amounts of effort to make udplite share as much code
with core UDP as possible.  All of that work is less valuable if we're
just going to slap a config option on udplite support.

It is also causing build failures, as reported on linux-next, showing
that the changeset was not tested very well.  In fact, this is the
second build failure resulting from the udplite change.

Finally, the config options provided was a bool, instead of a modular
option.  Meaning the udplite code does not even get build tested
by allmodconfig builds, and furthermore the user is not presented
with a reasonable modular build option which is particularly needed
by distribution vendors.

YOSHIFUJI Hideaki 2334ecbdb2 [IPV6]: Sparse: Declare non-static ipv6_{route,icmp,frag}_sysctl_init() in header.
Fix the following sparse warnings:
| net/ipv6/route.c:2491:18: warning: symbol 'ipv6_route_sysctl_init' was not declared. Should it be static?
| net/ipv6/icmp.c:922:18: warning: symbol 'ipv6_icmp_sysctl_init' was not declared. Should it be static?
| net/ipv6/reassembly.c:628:6: warning: symbol 'ipv6_frag_sysctl_init' was not declared. Should it be static?

Daniel Lezcano e71e0349eb [NETNS][IPV6]: Make ip6_frags per namespace.
The ip6_frags is moved to the network namespace structure.  Because
there can be multiple instances of the network namespaces, and the
ip6_frags is no longer a global static variable, a helper function has
been added to facilitate the initialization of the variables.

Until the ipv6 protocol is not per namespace, the variables are
accessed relatively from the initial network namespace.

Daniel Lezcano 99bc9c4e45 [NETNS][IPV6]: Make bindv6only sysctl per namespace.
This patch moves the bindv6only sysctl to the network namespace
structure. Until the ipv6 protocol is not per namespace, the sysctl
variable is always from the initial network namespace.
