[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]: Cleanup IPv4 raw_seq_show.

2008-02-01T03:27:25+00:00

There is no need to use 128 bytes on the stack at all. Clean the code
in the IPv6 style.

[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]: Add namespace parameter to ip_route_output_flow.

2008-01-28T23:11:06+00:00

Needed to propagate it down to the __ip_route_output_key.

[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]: Add netns parameter to inet_(dev_)add_type.

2008-01-28T23:01:27+00:00

The patch extends the inet_addr_type and inet_dev_addr_type with the
network namespace pointer. That allows to access the different tables
relatively to the network namespace.

The modification of the signature function is reported in all the
callers of the inet_addr_type using the pointer to the well known
init_net.
