08de61beab [PFKEYV2]: Extension for dynamic update of endpoint address(es)
Extend PF_KEYv2 framework so that user application can take advantage
of MIGRATE feature via PF_KEYv2 interface. User application can either
send or receive an MIGRATE message to/from PF_KEY socket.

Detail information can be found in the internet-draft
<draft-sugimoto-mip6-pfkey-migrate>.

80c9abaabf [XFRM]: Extension for dynamic update of endpoint address(es)
Extend the XFRM framework so that endpoint address(es) in the XFRM
databases could be dynamically updated according to a request (MIGRATE
message) from user application. Target XFRM policy is first identified
by the selector in the MIGRATE message. Next, the endpoint addresses
of the matching templates and XFRM states are updated according to
the MIGRATE message.

84ff602efb [ATM]: Fix for crash in adummy_init()
This was reported by Ingo Molnar here,

http://lkml.org/lkml/2006/12/18/119

The problem is that adummy_init() depends on atm_init() , but adummy_init()
is called first.

So I put atm_init() into subsys_initcall which seems appropriate, and it
will still get module_init() if it becomes a module.

Interesting to note that you could crash your system here if you just load
the modules in the wrong order.

f5a6e01c09 [NET]: user of the jiffies rounding code: Networking
This patch introduces users of the round_jiffies() function in the
networking code.

These timers all were of the "about once a second" or "about once
every X seconds" variety and several showed up in the "what wakes the
cpu up" profiles that the tickless patches provide.  Some timers are
highly dynamic based on network load; but even on low activity systems
they still show up so the rounding is done only in cases of low
activity, allowing higher frequency timers in the high activity case.

The various hardware watchdogs are an obvious case; they run every 2
seconds but aren't otherwise specific of exactly when they need to
run.

6f74651ae6 [TCP]: Seperate DSACK from SACK fast path
Move DSACK code outside the SACK fast-path checking code. If the DSACK
determined that the information was too old we stayed with a partial cache
copied. Most likely this matters very little since the next packet will not be
DSACK and we will find it in the cache. but it's still not good form and there
is little reason to couple the two checks.

Since the SACK receive cache doesn't need the data to be in host order we also
remove the ntohl in the checking loop.

Both aux data and sockaddr tries to use the same buffer which
obviously doesn't work.  We just happen to have 4 bytes free in
the skb->cb if you take away the maximum length of sockaddr_ll.
That's just enough to store the one piece of info from aux data
that we can't generate at recvmsg(2) time.

This is what the following patch does.

8dc4194474 [PACKET]: Add optional checksum computation for recvmsg
This patch is needed to make ISC's DHCP server (and probably other
DHCP servers/clients using AF_PACKET) to be able to serve another
client on the same Xen host.

The problem is that packets between different domains on the same
Xen host only have partial checksums.  Unfortunately this piece of
information is not passed along in AF_PACKET unless you're using
the mmap interface.  Since dhcpd doesn't support packet-mmap, UDP
packets from the same host come out with apparently bogus checksums.

This patch adds a mechanism for AF_PACKET recvmsg(2) to return the
status along with the packet.  It does so by adding a new cmsg that
contains this information along with some other relevant data such
as the original packet length.

I didn't include the time stamp information since there is already
a cmsg for that.

This patch also changes the mmap code to set the CSUMNOTREADY flag
on all packets instead of just outoing packets on cooked sockets.

239a87c876 [NET_SCHED]: act_ipt: fix regression in ipt action
The x_tables patch broke target module autoloading in the ipt action
by replacing the ipt_find_target call (which does autoloading) by
xt_find_target (which doesn't do autoloading). Additionally xt_find_target
may return ERR_PTR values in case of an error, which are not handled.

Use xt_request_find_target, which does both autoloading and ERR_PTR
handling properly. Also don't forget to drop the target module reference
again when xt_check_target fails.

When processing a HEARTBEAT-ACK it's possible that the transport rto
timers will not be updated because a prior T3-RTX processing would
have cleared the rto_pending flag on the transport.  However, if
we received a valid HEARTBEAT-ACK, we want to force update the

29556526b9 [IPV6]: fix BUG of ndisc_send_redirect()
When I tested IPv6 redirect function about kernel 2.6.19.1, and found
that the kernel can send redirect packets whose target address is global
address, and the target is not the actual endpoint of communication.

  But the criteria conform to RFC2461, the target address defines as
following:

  Target Address An IP address that is a better first hop to use for
                 he ICMP Destination Address.  When the target is
                 the actual endpoint of communication, i.e., the
                 destination is a neighbor, the Target Address field
                 MUST contain the same value as the ICMP Destination
                 Address field.  Otherwise the target is a better
                 first-hop router and the Target Address MUST be the
                 router's link-local address so that hosts can
                 uniquely identify routers.

According to this definition, when a router redirect to a host, the
target address either the better first-hop router's link-local address
or the same as the ICMP destination address field. But the function of
ndisc_send_redirect() in net/ipv6/ndisc.c, does not check the target
address correctly.

There is another definition about receive Redirect message in RFC2461:

8.1.  Validation of Redirect Messages

   A host MUST silently discard any received Redirect message that does
   not satisfy all of the following validity checks:
   ......
   - The ICMP Target Address is either a link-local address (when
     redirected to a router) or the same as the ICMP Destination
     Address (when redirected to the on-link destination).
   ......

And the receive redirect function of ndisc_redirect_rcv() implemented
this definition, checks the target address correctly.
    if (ipv6_addr_equal(dest, target)) {
        on_link = 1;
    } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) {
        ND_PRINTK2(KERN_WARNING
               "ICMPv6 Redirect: target address is not link-local.\n");
        return;
    }

So, I think the send redirect function must check the target address
also.

250f391518 [PATCH] knfsd: fix an NFSD bug with full sized, non-page-aligned reads
NFSd assumes that largest number of pages that will be needed for a
request+response is 2+N where N pages is the size of the largest permitted
read/write request.  The '2' are 1 for the non-data part of the request, and 1
for the non-data part of the reply.

However, when a read request is not page-aligned, and we choose to use
->sendfile to send it directly from the page cache, we may need N+1 pages to
hold the whole reply.  This can overflow and array and cause an Oops.

This patch increases size of the array for holding pages by one and makes sure
that entry is NULL when it is not in use.

6640e69731 [IPV4]: Fix the fib trie iterator to work with a single entry routing tables
In a kernel with trie routing enabled I had a simple routing setup
with only a single route to the outside world and no default
route. "ip route table list main" showed my the route just fine but
/proc/net/route was an empty file.  What was going on?

Thinking it was a bug in something I did and I looked deeper.  Eventually
I setup a second route and everything looked correct, huh?  Finally I
realized that the it was just the iterator pair in fib_trie_get_first,
fib_trie_get_next just could not handle a routing table with a single entry.

So to save myself and others further confusion, here is a simple fix for
the fib proc iterator so it works even when there is only a single route
in a routing table.

fb7e2399ec [TCP]: skb is unexpectedly freed.
I encountered a kernel panic with my test program, which is a very
simple IPv6 client-server program.

The server side sets IPV6_RECVPKTINFO on a listening socket, and the
client side just sends a message to the server.  Then the kernel panic
occurs on the server.  (If you need the test program, please let me
know. I can provide it.)

This problem happens because a skb is forcibly freed in
tcp_rcv_state_process().

When a socket in listening state(TCP_LISTEN) receives a syn packet,
then tcp_v6_conn_request() will be called from
tcp_rcv_state_process().  If the tcp_v6_conn_request() successfully
returns, the skb would be discarded by __kfree_skb().

However, in case of a listening socket which was already set
IPV6_RECVPKTINFO, an address of the skb will be stored in
treq->pktopts and a ref count of the skb will be incremented in
tcp_v6_conn_request().  But, even if the skb is still in use, the skb
will be freed.  Then someone still using the freed skb will cause the
kernel panic.

I suggest to use kfree_skb() instead of __kfree_skb().

ffed53d25b [NETFILTER]: nf_nat: fix hanging connections when loading the NAT module
When loading the NAT module, existing connection tracking entries don't
have room for NAT information allocated and packets are dropped, causing
hanging connections. They really should be entered into the NAT table
as NULL mappings, but the current allocation scheme doesn't allow this.

For now simply accept those packets to avoid the hanging connections.

When IPv6 connection tracking splits up a defragmented packet into
its original fragments, the packets are taken from a list and are
passed to the network stack with skb->next still set. This causes
dev_hard_start_xmit to treat them as GSO fragments, resulting in
a use after free when connection tracking handles the next fragment.

When this code was converted to use sk_for_each() the
logic for the "best hash chain length" code was reversed,
breaking everything.

The original code was of the form:

			size = 0;
			do {
				if (++size >= best_size_so_far)
					goto next;
			} while ((sk = sk->next) != NULL);
			best_size_so_far = size;
			best = result;
		next:;

and this got converted into:

			sk_for_each(sk2, node, head)
				if (++size < best_size_so_far) {
					best_size_so_far = size;
					best = result;
				}

Which does something very very different from the original.

The signature of work functions changed recently from a context

the ieee80211softmac code, because the ieee80211softmac_assox_work
function has  been called directly with a parameter explicitly
casted to (void*). This compiled correctly but resulted in a
softlock, because mutex_lock was called with the wrong memory
address. The patch fixes the problem. Another issue was a wrong

Also removed the sctp_local_addr_lock() which is no longer needed as we
now use list_for_each_safe() to traverse this list. This fixes the bugs

The following patch seems to work for me, but this code has behaved this
way for a while, so don't know if it will break any existing apps.

832e3ca62d [DCCP] ccid3: return value in ccid3_hc_rx_calc_first_li
In a recent patch we introduced invalid return codes which will result in the
opposite of what is intended (i.e. send more packets in face of peculiar
network conditions).

This fixes it by returning ~0 which means not calculated as per
dccp_li_hist_calc_i_mean.

e1b4b9f398 [NETFILTER]: {ip,ip6,arp}_tables: fix exponential worst-case search for loops
If we come to node we'd already marked as seen and it's not a part of path
(i.e. we don't have a loop right there), we already know that it isn't a
part of any loop, so we don't need to revisit it.

That speeds the things up if some chain is refered to from several places
and kills O(exp(table size)) worst-case behaviour (without sleeping,
at that, so if you manage to self-LART that way, you are SOL for a long
time)...

5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.
