[IPV6]: Fix ipv6 address fetching in raw6_icmp_error().

2008-04-14T06:14:15+00:00

Fixes kernel bugzilla 10437

Based almost entirely upon a patch by Dmitry Butskoy.

When deciding what raw sockets to deliver the ICMPv6
to, we should use the addresses in the ICMPv6 quoted
IPV6 header, not the top-level one.

[RAW]: Wrong content of the /proc/net/raw6.

2008-02-01T03:27:26+00:00

The address of IPv6 raw sockets was shown in the wrong format, from
IPv4 ones.  The problem has been introduced by the commit
42a73808ed4f30b739eb52bcbb33a02fe62ceef5 ("[RAW]: Consolidate proc
interface.")

Thanks to Adrian Bunk who originally noticed the problem.

[RAW]: Family check in the /proc/net/raw[6] is extra.

2008-02-01T03:27:24+00:00

Different hashtables are used for IPv6 and IPv4 raw sockets, so no
need to check the socket family in the iterator over hashtables. Clean
this out.

[NET]: Introducing socket mark socket option.

2008-02-01T03:27:19+00:00

A userspace program may wish to set the mark for each packets its send
without using the netfilter MARK target. Changing the mark can be used
for mark based routing without netfilter or for packet filtering.

It requires CAP_NET_ADMIN capability.

[NETNS][RAW]: Create the /proc/net/raw(6) in each namespace.

2008-01-28T23:02:07+00:00

To do so, just register the proper subsystem and create files in
->init callbacks.

No other special per-namespace handling for raw sockets is required.

[NETNS][RAW]: Eliminate explicit init_net references.

2008-01-28T23:02:06+00:00

Happily, in all the rest places (->bind callbacks only), that require the
struct net, we have a socket, so get the net from it.

[NETNS][RAW]: Make /proc/net/raw(6) show per-namespace socket list.

2008-01-28T23:02:06+00:00

Pull the struct net pointer up to the showing functions
to filter the sockets depending on their namespaces.

[NETNS][RAW]: Make ipv[46] raw sockets lookup namespaces aware.

2008-01-28T23:02:05+00:00

This requires just to pass the appropriate struct net pointer
into __raw_v[46]_lookup and skip sockets that do not belong
to a needed namespace.

The proper net is get from skb->dev in all the cases.

[NETNS][IPV6]: inet6_addr - check ipv6 address per namespace

2008-01-28T23:01:44+00:00

When a new address is added, we must check if the new address does not
already exists.  This patch makes this check to be aware of a network
namespace, so the check will look if the address already exists for
the specified network namespace. While the addresses are browsed, the
addresses which do not belong to the namespace are discarded.

[IPV6]: fix section mismatch warnings

2008-01-28T22:57:46+00:00

Removed useless and buggy __exit section in the different
ipv6 subsystems. Otherwise they will be called inside an
init section during rollbacking in case of an error in the
protocol initialization.
