e6eb307d48 [I/OAT]: Remove CPU hotplug lock from net_dma_rebalance
Remove the lock_cpu_hotplug()/unlock_cpu_hotplug() calls from
net_dma_rebalance

The lock_cpu_hotplug()/unlock_cpu_hotplug() sequence in
net_dma_rebalance is both incorrect (as pointed out by David Miller)
because lock_cpu_hotplug() may sleep while the net_dma_event_lock
spinlock is held, and unnecessary (as pointed out by Andrew Morton) as
spin_lock() disables preemption which protects from CPU hotplug
events.

9bbf28a1ff [DECNET]: Fix for routing bug
This patch fixes a bug in the DECnet routing code where we were
selecting a loopback device in preference to an outward facing device
even when the destination was known non-local. This patch should fix

dc49c1f94e [AF_UNIX]: Kernel memory leak fix for af_unix datagram getpeersec patch
From: Catherine Zhang <cxzhang@watson.ibm.com>

This patch implements a cleaner fix for the memory leak problem of the
original unix datagram getpeersec patch.  Instead of creating a
security context each time a unix datagram is sent, we only create the
security context when the receiver requests it.

This new design requires modification of the current
unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely,
secid_to_secctx and release_secctx.  The former retrieves the security
context and the latter releases it.  A hook is required for releasing
the security context because it is up to the security module to decide
how that's done.  In the case of Selinux, it's a simple kfree
operation.

76f10ad0e6 [NET]: Remove lockdep_set_class() call from skb_queue_head_init().
The skb_queue_head_init() function is used both in drivers for private use
and in the core networking code.  The usage models are vastly set of
functions that is only softirq safe; while the driver usage tends to be
more limited to a few hardirq safe accessor functions.  Rather than
annotating all 133+ driver usages, for now just split this lock into a per
queue class.  This change is obviously safe and probably should make
2.6.18.

dafee49085 [IPV6]: SNMPv2 "ipv6IfStatsOutFragCreates" counter error
When I tested linux kernel 2.6.71.7 about statistics
"ipv6IfStatsOutFragCreates", and found that it couldn't increase
correctly. The criteria is RFC 2465:

  ipv6IfStatsOutFragCreates OBJECT-TYPE
      SYNTAX      Counter32
      MAX-ACCESS  read-only
      STATUS      current
      DESCRIPTION
         "The number of output datagram fragments that have
         been generated as a result of fragmentation at
         this output interface."
      ::= { ipv6IfStatsEntry 15 }

I think there are two issues in Linux kernel. 
1st:
RFC2465 specifies the counter is "The number of output datagram
fragments...". I think increasing this counter after output a fragment
successfully is better. And it should not be increased even though a
fragment is created but failed to output.

2nd:
If we send a big ICMP/ICMPv6 echo request to a host, and receive
ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in
Linux kernel first fragmentation occurs in ICMP layer(maybe saying
transport layer is better), but this is not the "real"
fragmentation,just do some "pre-fragment" -- allocate space for date,
and form a frag_list, etc. The "real" fragmentation happens in IP layer
-- set offset and MF flag and so on. So I think in "fast path" for
ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by
upper layer we should also increase "ipv6IfStatsOutFragCreates".

32c524d1c4 [IPV6]: SNMPv2 "ipv6IfStatsInHdrErrors" counter error
When I tested Linux kernel 2.6.17.7 about statistics

b60dfc6c20 [NET]: Kill the WARN_ON() calls for checksum fixups.
We have a more complete solution in the works, involving
the seperation of CHECKSUM_HW on input vs. output, and
having netfilter properly do incremental checksums.

But that is a very involved patch and is thus 2.6.19
material.

What we have now is infinitely better than the past,
wherein all TSO packets were dropped due to corrupt
checksums as soon at the NAT module was loaded.  At
least now, the checksums do get fixed up, it just
isn't the cleanest nor most optimal solution.

52499afe40 [TCP]: Process linger2 timeout consistently.
Based upon guidance from Alexey Kuznetsov.

When linger2 is active, we check to see if the fin_wait2
timeout is longer than the timewait.  If it is, we schedule
the keepalive timer for the difference between the timewait
timeout and the fin_wait2 timeout.

When this orphan socket is seen by tcp_keepalive_timer()
it will try to transform this fin_wait2 socket into a
fin_wait2 mini-socket, again if linger2 is active.

Not all paths were setting this initial keepalive timer correctly.
The tcp input path was doing it correctly, but tcp_close() wasn't,
potentially making the socket linger longer than it really needs to.

a280b89982 [SECURITY] secmark: nul-terminate secdata
The patch below fixes a problem in the iptables SECMARK target, where
the user-supplied 'selctx' string may not be nul-terminated.

From initial analysis, it seems that the strlen() called from
selinux_string_to_sid() could run until it arbitrarily finds a zero,
and possibly cause a kernel oops before then.

The impact of this appears limited because the operation requires
CAP_NET_ADMIN, which is essentially always root.  Also, the module is
not yet in wide use.

3687b1dc6f [TCP]: SNMPv2 tcpAttemptFails counter error
Refer to RFC2012, tcpAttemptFails is defined as following:
  tcpAttemptFails OBJECT-TYPE
      SYNTAX      Counter32
      MAX-ACCESS  read-only
      STATUS      current
      DESCRIPTION
              "The number of times TCP connections have made a direct
              transition to the CLOSED state from either the SYN-SENT
              state or the SYN-RCVD state, plus the number of times TCP
              connections have made a direct transition to the LISTEN
              state from the SYN-RCVD state."
      ::= { tcp 7 }

When I lookup into RFC793, I found that the state change should occured
under following condition:
  1. SYN-SENT -> CLOSED
     a) Received ACK,RST segment when SYN-SENT state.

  2. SYN-RCVD -> CLOSED
     b) Received SYN segment when SYN-RCVD state(came from LISTEN).
     c) Received RST segment when SYN-RCVD state(came from SYN-SENT).
     d) Received SYN segment when SYN-RCVD state(came from SYN-SENT).

  3. SYN-RCVD -> LISTEN
     e) Received RST segment when SYN-RCVD state(came from LISTEN).

In my test, those direct state transition can not be counted to
tcpAttemptFails.

497c615aba [IPV6]: Audit all ip6_dst_lookup/ip6_dst_store calls
The current users of ip6_dst_lookup can be divided into two classes:

1) The caller holds no locks and is in user-context (UDP).
2) The caller does not want to lookup the dst cache at all.

The second class covers everyone except UDP because most people do
the cache lookup directly before calling ip6_dst_lookup.  This patch
adds ip6_sk_dst_lookup for the first class.

Similarly ip6_dst_store users can be divded into those that need to
take the socket dst lock and those that don't.  This patch adds
__ip6_dst_store for those (everyone except UDP/datagram) that don't
need an extra lock.

ce38cac482 [PATCH] rivafb/nvidiafb: race between register_framebuffer and *_bl_init
Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode.  In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.

This fixes booting current git on a PB 6,1.  In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.

Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery
lifetime.  The solution is to enable suspend-to-D2 on these machines.  They
are whitelisted through their subsystem vendor/device ID.  This fixes
http://bugzilla.kernel.org/show_bug.cgi?id=3022

The patch introduces a framework to alter the pm_mode and reinit_func fields
of the radeonfb_info structure based on a whitelist.  This should facilitate
future hardware-dependent workarounds.  The workaround for the Samsung P35
that is already in the radeonfb code has been rewritten using this framework.

The behavior can be overridden with module options:

i)  video=radeonfb:force_sleep=1
    enable suspend-to-D2 also on non-whitelisted machines (useful for
    testing new notebook models),

ii) video=radeonfb:ignore_devlist=1
    Disable checking the whitelist and do not apply any workarounds.

256154fbc3 [PATCH] fbdev: statically link the framebuffer notification functions
The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events.  However, these subsystems, as a whole, can function
independently from the framebuffer layer.  But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.

To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

834a9b8ca7 [PATCH] 9p: fix fid behavior on failed remove
Based on a bug report from Russ Ross <russruss@gmail.com>

According to the spec:

"The remove request asks the file server both to remove the file
 represented by fid and to clunk the fid, even if the remove fails."

but the Linux client seems to expect the fid to be valid after a failed
remove attempt.  Specifically, I'm getting this behavior when attempting to
remove a non-empty directory.

0e31f51d81 [PATCH] ext3 -nobh option causes oops
For files other than IFREG, nobh option doesn't make sense.  Modifications
to them are journalled and needs buffer heads to do that.  Without this

bc65ac6a0f [PATCH] freevxfs: Add missing lock_kernel() to vxfs_readdir
Commit 7b2fd697427e73c81d5fa659efd91bd07d303b0e in the historical GIT tree
stopped calling the readdir member of a file_operations struct with the big
kernel lock held, and fixed up all the readdir functions to do their own
locking.  However, that change added calls to unlock_kernel() in
vxfs_readdir, but no call to lock_kernel().  Fix this by adding a call to
lock_kernel().

0a0898cf41 [PATCH] fuse: use jiffies_64
It is entirely possible (though rare) that jiffies half-wraps around, while a
dentry/inode remains in the cache.  This could mean that the dentry/inode is
not invalidated for another half wraparound-time.

To get around this problem, use 64-bit jiffies.  The only problem with this is
that dentry->d_time is 32 bits on 32-bit archs.  So use d_fsdata as the high
32 bits.  This is an ugly hack, but far simpler, than having to allocate
private data just for this purpose.

Since 64-bit jiffies can be assumed never to wrap around, simple comparison
can be used, and a zero time value can represent "invalid".
