be94db9dda netfilter: ipset: dumping error triggered removing references twice
If there was a dumping error in the middle, the set-specific variable was
not zeroed out and thus the 'done' function of the dumping wrongly tried
to release the already released reference of the set. The already released
reference was caught by __ip_set_put and triggered a kernel BUG message.
Reported by Jean-Philippe Menil.

088067f4f1 netfilter: ipset: autoload set type modules safely
Jan Engelhardt noticed when userspace requests a set type unknown
to the kernel, it can lead to a loop due to the unsafe type module
loading. The issue is fixed in this patch.

75f2811c64 ipv6: Add fragment reporting to ipv6_skip_exthdr().
While parsing through IPv6 extension headers, fragment headers are
skipped making them invisible to the caller.  This reports the
fragment offset of the last header in order to make it possible to
determine whether the packet is fragmented and, if so whether it is
a first or last fragment.

89dc79b787 netfilter: ipset: hash:net,iface fixed to handle overlapping nets behind different interfaces
If overlapping networks with different interfaces was added to
the set, the type did not handle it properly. Example

    ipset create test hash:net,iface
    ipset add test 192.168.0.0/16,eth0
    ipset add test 192.168.0.0/24,eth1

Now, if a packet was sent from 192.168.0.0/24,eth0, the type returned
a match.

In the patch the algorithm is fixed in order to correctly handle
overlapping networks.

Limitation: the same network cannot be stored with more than 64 different
interfaces in a single set.

dec17b7451 Remove redundant linux/version.h includes from net/
It was suggested by "make versioncheck" that the follwing includes of
linux/version.h are redundant:

  /home/jj/src/linux-2.6/net/caif/caif_dev.c: 14 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/caif/chnl_net.c: 10 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/ipv4/gre.c: 19 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/ipset/ip_set_core.c: 20 linux/version.h not needed.
  /home/jj/src/linux-2.6/net/netfilter/xt_set.c: 16 linux/version.h not needed.

and it seems that it is right.

Beyond manually inspecting the source files I also did a few build
tests with various configs to confirm that including the header in
those files is indeed not needed.

Here's a patch to remove the pointless includes.

by "readding" the element with the "-exist" flag. That means the timeout

c7ac8679be rtnetlink: Compute and store minimum ifinfo dump size
The message size allocated for rtnl ifinfo dumps was limited to
a single page.  This is not enough for additional interface info
available with devices that support SR-IOV and caused a bug in
which VF info would not be displayed if more than approximately
40 VFs were created per interface.

Implement a new function pointer for the rtnl_register service that will
calculate the amount of data required for the ifinfo dump and allocate
enough data to satisfy the request.

5f52bc3cdd netfilter: ipset: send error message manually
When a message carries multiple commands and one of them triggers
an error, we have to report to the userspace which one was that.
The line number of the command plays this role and there's an attribute
reserved in the header part of the message to be filled out with the error
line number. In order not to modify the original message received from
the userspace, we construct a new, complete netlink error message and
modifies the attribute there, then send it.
Netlink is notified not to send its ACK/error message.

724bab476b netfilter: ipset: fix linking with CONFIG_IPV6=n
Add a dummy ip_set_get_ip6_port function that unconditionally
returns false for CONFIG_IPV6=n and convert the real function
to ipv6_skip_exthdr() to avoid pulling in the ip6_tables module
when loading ipset.
