463c319726 [PATCH] r/o bind mounts: get callers of vfs_mknod/create/mkdir()
This takes care of all of the direct callers of vfs_mknod().
Since a few of these cases also handle normal file creation
as well, this also covers some calls to vfs_create().

So that we don't have to make three mnt_want/drop_write()
calls inside of the switch statement, we move some of its
logic outside of the switch and into a helper function
suggested by Christoph.

This also encapsulates a fix for mknod(S_IFREG) that Miklos
found.

d1643d24c6 [NET]: Fix and allocate less memory for ->priv'less netdevices
This patch effectively reverts commit d0498d9ae1
aka "[NET]: Do not allocate unneeded memory for dev->priv alignment."
It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST
removal.

For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size"
was also 2048 bytes, but allocator with debugging options turned on started
giving out !32-byte aligned memory resulting in redzones overwrites.

Patch does small optimization in ->priv'less case: bumping size to next
32-byte boundary was always done to ensure ->priv will also be aligned.
But, no ->priv, no need to do that.

Fixes bugzilla #8895

If a super-tree leaf has 'rt' assigned to it and we
get an error from fib6_add_rt2node(), we'll leave
a reference to 'rt' in pn->leaf and then do an
unconditional dst_free().

We should prune such references.

794eb6bf20 [NETLABEL]: Fix NULL deref in netlbl_unlabel_staticlist_gen() if ifindex not found
dev_get_by_index() may return NULL if nothing is found. In 
net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the 
function is called, but the return value is never checked. If it returns 
NULL then we'll deref a NULL pointer on the very next line.
I checked the callers, and I don't think this can actually happen today, 
but code changes over time and in the future it might happen and it does 
no harm to be defensive and check for the failure, so that if/when it 
happens we'll fail gracefully instead of crashing.

As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.

Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
 `- tcp_v4_syn_recv_sock
     `- __inet_inherit_port

0f39cf3d54 IB/core: Add support for "send with invalidate" work requests
Add a new IB_WR_SEND_WITH_INV send opcode that can be used to mark a
"send with invalidate" work request as defined in the iWARP verbs and
the InfiniBand base memory management extensions.  Also put "imm_data"
and a new "invalidate_rkey" member in a new "ex" union in struct
ib_send_wr. The invalidate_rkey member can be used to pass in an
R_Key/STag to be invalidated.  Add this new union to struct
ib_uverbs_send_wr.  Add code to copy the invalidate_rkey field in
ib_uverbs_post_send().

Fix up low-level drivers to deal with the change to struct ib_send_wr,
and just remove the imm_data initialization from net/sunrpc/xprtrdma/,
since that code never does any send with immediate operations.

Also, move the existing IB_DEVICE_SEND_W_INV flag to a new bit, since
the iWARP drivers currently in the tree set the bit.  The amso1100
driver at least will silently fail to honor the IB_SEND_INVALIDATE bit
if passed in as part of userspace send requests (since it does not
implement kernel bypass work request queueing).  Remove the flag from
all existing drivers that set it until we know which ones are OK.

The values chosen for the new flag is not consecutive to avoid clashing
with flags defined in the XRC patches, which are not merged yet but
which are already in use and are likely to be merged soon.

This resurrects a patch sent long ago by Mikkel Hagen <mhagen@iol.unh.edu>.

245cbe7a65 mac80211: fix key todo list order
When we add multiple todo entries, we rely on them being executed
mostly in the right order, especially when a key is being replaced.
But when a default key is replaced, the todo list order will differ
from the order when the key being replaced is not a default key, so
problems will happen. Hence, just move each todo item to the end of
the list when it is added so we can in the other code ensure that
hw accel for a key will be disabled before it is enabled for the
replacement.

d18ef29f34 mac80211: no BSS changes to driver from beacons processed during scanning
There is no need to send BSS changes to driver from beacons processed
during scanning. We are more interested in beacons from an AP with which
we are associated - these will still be used to send updates to driver as
the beacons are received without scanning.

This change·removes the requirement that bss_info_changed needs to be atomic.
The beacons received during scanning are processed from a tasklet, but if we
do not call bss_info_changed for these beacons there is no need for it to be
atomic. This function (bss_info_changed) is called either from workqueue or
ioctl in all other instances.

3a24576690 mac80211: fix key hwaccel race
The previous key locking patch left a small race: it would be possible
to add a key and take the interface down before the key todo is run so
that hwaccel for that key is enabled on an interface that is down. Avoid
this by running the todo list when an interface is brought up or down.

This patch also fixes a small bug: before this change, a few functions
used the key list without the lock that protects it.

d0498d9ae1 [NET]: Do not allocate unneeded memory for dev->priv alignment.
The alloc_netdev_mq() tries to produce 32-bytes alignment for both
the net_device itself and its private data. The second alignment is
achieved by adding the NETDEV_ALIGN_CONST to the whole size of
the memory to be allocated.

However, for those devices that do not need the private area, this
addition just makes the net_device weight 1024 + 32 = 1068 bytes,
i.e. consume twice as much memory.

Since loopback device is such (sizeof_priv == 0 for it), and each
net namespace creates one, this can save a noticeable amount of
memory for kernel with net namespaces turned on.

After this set the lo device is actually allocated from a size-1024
kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on.
