4d46861be6 [DCCP]: Correctly split CCID half connections
This fixes a bug caused by a previous patch, which causes DCCP servers in
LISTEN state to not receive packets.

This patch changes the logic so that
 * servers in either LISTEN or OPEN state get the RX half connection packets
 * clients in OPEN state get the TX half connection packets

This reverts two changes:

8488df894d
248f06726e

A backlog value of N really does mean allow "N + 1" connections
to queue to a listening socket.  This allows one to specify
"0" as the backlog and still get 1 connection.

42a7fc4a65 [PATCH] knfsd: provide sunrpc pool_mode module option
Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to
choose the mode for mapping NFS thread service pools to CPUs.  Values are:

auto	    choose a mapping mode heuristically
global	    (default, same as the pre-2.6.19 code) a single global pool
percpu	    one pool per CPU
pernode	    one pool per NUMA node

Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch
makes the default "global".

The pool mode can be changed after boot/modprobe using /sys, if the NFS and
lockd services have been shut down.  A useful side effect of this change is to
fix a small memory leak when unloading the module.

cda1fd4abd [PATCH] knfsd: fix recently introduced problem with shutting down a busy NFS server
When the last thread of nfsd exits, it shuts down all related sockets.  It
currently uses svc_close_socket to do this, but that only is immediately
effective if the socket is not SK_BUSY.

If the socket is busy - i.e.  if a request has arrived that has not yet been
processes - svc_close_socket is not effective and the shutdown process spins.

So create a new svc_force_close_socket which removes the SK_BUSY flag is set
and then calls svc_close_socket.

Also change some open-codes loops in svc_destroy to use
list_for_each_entry_safe.

7a37f5787e [PATCH] knfsd: use recv_msg to get peer address for NFSD instead of code-copying
The sunrpc server code needs to know the source and destination address for
UDP packets so it can reply properly.  It currently copies code out of the
network stack to pick the pieces out of the skb.  This is ugly and causes
compile problems with the IPv6 stuff.

So, rip that out and use recv_msg instead.  This is a much cleaner interface,
but has a slight cost in that the checksum is now checked before the copy, so
we don't benefit from doing both at the same time.  This can probably be
fixed.

a816c7c712 bonding: Improve IGMP join processing
In active-backup mode, the current bonding code duplicates IGMP
traffic to all slaves, so that switches are up to date in case of a
failover from an active to a backup interface.  If bonding then fails
back to the original active interface, it is likely that the "active
slave" switch's IGMP forwarding for the port will be out of date until
some event occurs to refresh the switch (e.g., a membership query).

	This patch alters the behavior of bonding to no longer flood
IGMP to all ports, and to issue IGMP JOINs to the newly active port at
the time of a failover.  This insures that switches are kept up to date
for all cases.

	"GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally
reported this problem, and included a patch.  His original patch was
modified by Jay Vosburgh to additionally remove the existing IGMP flood
behavior, use RCU, streamline code paths, fix trailing white space, and
adjust for style.

ec68e97ded [NETFILTER]: conntrack: fix {nf,ip}_ct_iterate_cleanup endless loops
Fix {nf,ip}_ct_iterate_cleanup unconfirmed list handling:

- unconfirmed entries can not be killed manually, they are removed on
  confirmation or final destruction of the conntrack entry, which means
  we might iterate forever without making forward progress.

  This can happen in combination with the conntrack event cache, which
  holds a reference to the conntrack entry, which is only released when
  the packet makes it all the way through the stack or a different
  packet is handled.

- taking references to an unconfirmed entry and using it outside the
  locked section doesn't work, the list entries are not refcounted and
  another CPU might already be waiting to destroy the entry

What the code really wants to do is make sure the references of the hash
table to the selected conntrack entries are released, so they will be
destroyed once all references from skbs and the event cache are dropped.

Since unconfirmed entries haven't even entered the hash yet, simply mark
them as dying and skip confirmation based on that.

c6387a8694 [NetLabel]: Verify sensitivity level has a valid CIPSO mapping
The current CIPSO engine has a problem where it does not verify that
the given sensitivity level has a valid CIPSO mapping when the "std"
CIPSO DOI type is used.  The end result is that bad packets are sent
on the wire which should have never been sent in the first place.
This patch corrects this problem by verifying the sensitivity level
mapping similar to what is done with the category mapping.  This patch
also changes the returned error code in this case to -EPERM to better
match what the category mapping verification code returns.

without holding further locks. netlink_unicast calls netlink_trim
with the result of gfp_any() for the gfp flags, which are passed
down to pskb_expand_header. gfp_any() only checks for softirq
context and returns GFP_KERNEL, resulting in this warning:

2c12a74cc4 [IPV6]: anycast refcnt fix
This patch fixes a bug in Linux IPv6 stack which caused anycast address
to be added to a device prior DAD has been completed. This led to
incorrect reference count which resulted in infinite wait for
unregister_netdevice completion on interface removal.

aef8811abb [XFRM]: Fix oops in xfrm4_dst_destroy()
With 2.6.21-rc1, I get an oops when running 'ifdown eth0' and an IPsec
connection is active. If I shut down the connection before running 'ifdown
eth0', then there's no problem.  The critical operation of this script is to
kill dhcpd.

The problem is probably caused by commit with git identifier
4337226228 (Linus tree) "[IPSEC]: IPv4 over IPv6
IPsec tunnel".

This patch fixes that oops. I don't know the network code of the Linux
kernel in deep, so if that fix is wrong, please change it. But please
fix the oops. :)

1845a579e0 [SCTP]: Strike the transport before updating rto.
Once we reach a point where we exceed the max.path.retrans, strike the

8c4a2d41a7 [SCTP]: Fix connection hang/slowdown with PR-SCTP
The problem that this patch corrects happens when all of the following
conditions are satisfisfied:
 1.  PR-SCTP is used and the timeout on the chunks is set below RTO.Max.
 2.  One of the paths on a multihomed associations is brought down.

In this scenario, data will expire within the rto of the initial
transmission and will never be retransmitted.  However this data still
fills the send buffer and is counted against the association as outstanding
data.  This causes any new data not to be sent and retransmission to not
happen.

The fix is to discount the abandoned data from the outstanding count and
peers rwnd estimation.  This allows new data to be sent and a retransmission
timer restarted.  Even though this new data will most likely expire within
the rto, the timer still counts as a strike against the transport and forces
the FORWARD-TSN chunk to be retransmitted as well.
