netfilter: ebtables: make broute table work again
broute table init hook sets up the "br_should_route_hook" pointer,

commit
a386f99025f13b32502fe5dedf223c20d7283826
(bridge: add proper RCU annotation to should_route_hook)
introduced a typedef, and then changed this to:
br_should_route_hook_t *rhook;
[..]
rhook = rcu_dereference(br_should_route_hook);
if (*rhook(skb))
problem is that "br_should_route_hook" contains the address of the function,

netfilter: fix race in conntrack between dump_table and destroy
The netlink interface to dump the connection tracking table has a race
when entries are deleted at the same time. A customer reported a crash
and the backtrace showed thatctnetlink_dump_table was running while a
conntrack entry was being destroyed.
(see https://bugzilla.vyatta.com/show_bug.cgi?id=6402).
According to RCU documentation, when using hlist_nulls the reader
must handle the case of seeing a deleted entry and not proceed
further down the linked list. The old code would continue
which caused the scan to walk into the free list.
This patch uses locking (rather than RCU) for this operation which
is guaranteed safe, and no longer requires getting reference while
doing dump operation.

tcp: disallow bind() to reuse addr/port
inet_csk_bind_conflict() logic currently disallows a bind() if
it finds a friend socket (a socket bound on same address/port)
satisfying a set of conditions :
1) Current (to be bound) socket doesnt have sk_reuse set
OR
2) other socket doesnt have sk_reuse set
OR
3) other socket is in LISTEN state
We should add the CLOSE state in the 3) condition, in order to avoid two
REUSEADDR sockets in CLOSE state with same local address/port, since
this can deny further operations.
Note : a prior patch tried to address the problem in a different (and
buggy) way. (commit
fda48a0d7a8412ced tcp: bind() fix when many ports

ext4: fix trimming starting with block 0 with small blocksize
When s_first_data_block is not zero (which happens e.g. when block size is 1KB)
and trim ioctl is called to start trimming from block 0, the math in
ext4_get_group_no_and_offset() overflows. The overall result is that ioctl
returns EINVAL which is kind of unexpected and we probably don't want
userspace tools to bother with internal details of filesystem structure.
So just silently increase starting offset (and shorten length) when starting
block is below s_first_data_block.

As per the suggestion of Robert Richter the patch only adds the

The header asm/hvcall.h was previously included indirectly via

and the build breaks. This is easily fixed by including asm/hvcall.h
directly.
The VPHN feature is only meaningful on NUMA systems that implement
the SPLPAR option, so exclude the VPHN code on systems without
SPLPAR enabled.
Also, expose unmap_cpu_from_node() on systems with SPLPAR enabled,
even if CONFIG_HOTPLUG_CPU is disabled.
Lastly, map_cpu_to_node() is now needed by VPHN to manipulate the
node masks after boot time, so remove the __cpuinit annotation to

IB/qib: UD send with immediate receive completion has wrong size
The code to generate receive completion entries for UD send with
immediate contains the wrong payload length. This is because when the
code to compute the payload size was moved, the value of hdrsize
didn't get moved too. The fix is to update tlen directly.

IB/qib: Set port physical state even if other fields are invalid
The IBTA vol. 1 release 1.2.1 spec. says:
C14-24.2.1: If PortInfo:Portstate=Down, then a SubnSet(PortInfo) shall
make any changes it specifies to PortInfo:PortPhysicalState; any other
result is vendor-dependent.
The patch changes the error handling so that the reply says there are
invalid fields but still attempts to set fields that are in range
including PortInfo:PortPhysicalState.

IB/qib: Generate completion callback on errors
According to IBTA vol. 1, C11-30.1.1, a notification callback is
invoked if the CQ is armed for the next solicited completion event or
an error completion. The error case wasn't being generated correctly.
