e82041df5d bnx2x: Fix unrecognized SFP+ module after driver is loaded
When SFP+ module is plugged in after driver is already loaded, it may not be
recognized, so set SFP module recognition time up to 300ms, without resetting
the module power in the middle.

John W. Linville says:

====================
This is a batch of fixes intended for 3.7...

The biggest portion of this is a pull request from Johannes Berg:

"Please pull my mac80211.git tree per below to get a number of fixes. I
have included a patch from Antonio to fix a memcpy overrun, Felix's
patches for the antenna gain/tx power issues, a few mesh-related fixes
from Javier for mac80211 and my own patches to not access data that
might not be present in an skb at all as well as a patch (the duplicate
IE check one) to make mac80211 forward-compatible with potential future
spec extensions that use the same IE multiple times.

It's a bit bigger than I'd like maybe, but I think all of these are
worthwhile fixes at this point."

In addition...

Felix Fietkau fixes an ath9k use-after-free issue.

Stanislaw Gruszka adds a valid value check to rt2800.

Sven Eckelmann adds a check to only check a TID value in a BlockAck, for
frames that could be either a BlockAck or a normal Ack.

they are:

* Skip re-route in nf_nat code for ICMP traffic. If CONFIG_XFRM is

6fe7cc71bb ath9k: Test for TID only in BlockAcks while checking tx status
The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case
only one frame is currently available. The client will then answer using a
normal Ack instead of a BlockAck. This acknowledgement has no TID stored and
therefore the hardware is not able to provide us the corresponding TID.

The TID set by the hardware in the tx status descriptor has to be seen as
undefined and not as a valid TID value for normal acknowledgements. Doing
otherwise results in a massive amount of retransmissions and stalls of
connections.

Users may experience low bandwidth and complete connection stalls in
environments with transfers using multiple TIDs.

This regression was introduced in b11b160def
("ath9k: validate the TID in the tx status information").

8c6e30936a ath9k: fix stale pointers potentially causing access to free'd skbs
bf->bf_next is only while buffers are chained as part of an A-MPDU
in the tx queue. When a tid queue is flushed (e.g. on tearing down
an aggregation session), frames can be enqueued again as normal
transmission, without bf_next being cleared. This can lead to the
old pointer being dereferenced again later.

This patch might fix crashes and "Failed to stop TX DMA!" messages.

6dbda2d00d mac80211: make sure data is accessible in EAPOL check
The code to allow EAPOL frames even when the station
isn't yet marked associated needs to check that the
incoming frame is long enough and due to paged RX it
also can't assume skb->data contains the right data,
it must use skb_copy_bits(). Fix this to avoid using
data that doesn't really exist.

Linus Torvalds
561ec64ae6 VFS: don't do protected {sym,hard}links by default
In commit 800179c9b8 ("This adds symlink and hardlink restrictions to
the Linux VFS"), the new link protections were enabled by default, in
the hope that no actual application would care, despite it being
technically against legacy UNIX (and documented POSIX) behavior.

However, it does turn out to break some applications.  It's rare, and
it's unfortunate, but it's unacceptable to break existing systems, so
we'll have to default to legacy behavior.

In particular, it has broken the way AFD distributes files, see

  http://www.dwd.de/AFD/

along with some legacy scripts.

Distributions can end up setting this at initrd time or in system
scripts: if you have security problems due to link attacks during your
early boot sequence, you have bigger problems than some kernel sysctl
setting. Do:

	echo 1 > /proc/sys/fs/protected_symlinks
	echo 1 > /proc/sys/fs/protected_hardlinks

to re-enable the link protections.

Alternatively, we may at some point introduce a kernel config option
that sets these kinds of "more secure but not traditional" behavioural
options automatically.

f8295ec22c qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwan
These devices provide QMI and ethernet functionality via a standard CDC
ethernet descriptor.  But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface.  Thus blacklist the devices in cdc_ether and add their IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

39707c2a3b net: usb: Fix memory leak on Tx data path
Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor()
unanchors the urb but urb reference count remains same.
This causes the urb reference count to remain non-zero
after usb_free_urb() gets called and urb never gets freed.
Hence call usb_put_urb() after anchoring the urb to properly
balance the reference count for these deferred urbs. Also,
unanchor these deferred urbs during disconnect, to free them
up.

c6fdd8e5d0 bas_gigaset: fix pre_reset handling
The delayed work function int_in_work() may call usb_reset_device()
and thus, indirectly, the driver's pre_reset method. Trying to
cancel the work synchronously in that situation would deadlock.
Fix by avoiding cancel_work_sync() in the pre_reset method.

If the reset was NOT initiated by int_in_work() this might cause
int_in_work() to run after the post_reset method, with urb_int_in
already resubmitted, so handle that case gracefully.
