c995ae2259 tcp: Change return value of tcp_rcv_established()
tcp_rcv_established() returns only one value namely 0. We change the return
value to void (as suggested by David Miller).

After commit 0c24604b (tcp: implement RFC 5961 4.2), we no longer send RSTs in
response to SYNs. We can remove the check and processing on the return value of
tcp_rcv_established().

We also fix jtcp_rcv_established() in tcp_probe.c to match that of
tcp_rcv_established().

cc8c6c1b21 net: tcp_probe: adapt tbuf size for recent changes
With recent changes in tcp_probe module (e.g. f925d0a62d ("net: tcp_probe:
add IPv6 support")) we also need to take into account that tbuf needs to
be updated as format string will be further expanded. tbuf sits on the stack
in tcpprobe_read() function that is invoked when user space reads procfs
file /proc/net/tcpprobe, hence not fast path as in jtcp_rcv_established().
Having a size similarly as in sctp_probe module of 256 bytes is fully
sufficient for that, we need theoretical maximum of 252 bytes otherwise we
could get truncated.

cab6ce9ebe caif: add a sanity check to the tty name
"tty->name" and "name" are a 64 character buffers.  My static checker
complains because we add the "cf" on the front so it look like we are
copying a 66 character string into a 64 character buffer.

Also if the name is larger than IFNAMSIZ (16) it triggers a BUG_ON()
inside the call to alloc_netdev().

This is all under CAP_SYS_ADMIN so it's not a security fix, it just adds
a little robustness.

with RTNL). This change will also help in the future removal of reader

This patch aims to remove a use of the bond->lock for mutual exclusion
which will later allow easier migration to RCU of the users of this
functionality. We use RTNL as a synchronizing mechanism since it's
always held when send_peer_notif is set, and when it is decremented from
the notifier function. We can also drop some locking, and fix the
leakage of the send_peer_notif counter.

f7c6be404d vhost_net: correctly limit the max pending buffers
As Michael point out, We used to limit the max pending DMAs to get better cache
utilization. But it was not done correctly since it was one done when there's no
new buffers submitted from guest. Guest can easily exceeds the limitation by
keeping sending packets.

So this patch moves the check into main loop. Tests shows about 5%-10%
improvement on per cpu throughput for guest tx.

50ad076ba4 gianfar: Fix reported number of sent bytes to BQL
Fix the amount of sent bytes reported to BQL by reporting the
number of bytes on wire in the xmit routine, and recording that
value for each skb in order to be correctly confirmed on Tx
confirmation cleanup.

Reporting skb->len to BQL just before exiting xmit is not correct
due to possible insertions of TOE block and alignment bytes in the
skb->data, which are being stripped off by the controller before
transmission on wire.  This led to mismatch of (incorrectly)
reported bytes to BQL b/w xmit and Tx confirmation, resulting in
Tx timeout firing, for the h/w tx timestamping acceleration case.

There's no easy way to obtain the number of bytes on wire in the Tx
confirmation routine, so skb->cb is used to convey that information
from xmit to Tx confirmation, for now (as proposed by Eric). Revived
the currently unused GFAR_CB() construct for that purpose.

Store VID in ->vlan_id (if any), and remove the useless ->tag.

6f477d4201 bonding: remove bond_vlan_used()
We're using it currently to verify if we have vlans before getting the tag
from the skb we're about to send. It's useless because the vlan_get_tag()
verifies if the skb has the tag (and returns an error if not), and we can
receive tagged skbs only if we *already* have vlans.

Plus, the current RCUed implementation is kind of useless anyway - the we
can remove the last vlan in the moment we return from the function.

So remove the only usage of it and the whole function.

c12a22428a Merge branch 'for-davem' of git://gitorious.org/linux-can/linux-can-next
Marc Kleine-Budde says:

====================
this is a pull request for net-next. There are two patches from Gerhard
Sittig, which improves the clock handling on mpc5121. Oliver Hartkopp
provides a patch that adds a per rule limitation of frame hops.

e7abfe4092 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:

====================
Please accept this batch of updates intended for the 3.12 stream.

For the mac80211 bits, Johannes says this:

"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."

Also for mac80211:

"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."

And for iwlwifi:

"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."

Regarding the Bluetooth bits, Gustavo says:

"Patches to 3.12, here we have:

* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"

For the NFC bits, Samuel says:

"With this one we have:

- A few pn533 improvements and minor fixes. Testing our pn533 driver
  against Google's NCI stack triggered a few issues that we fixed now.
  We also added Tx fragmentation support to this driver.

- More NFC secure element handling. We added a GET_SE netlink command
  for getting all the discovered secure elements, and we defined 2
  additional secure element netlink event (transaction and connectivity).
  We also fixed a couple of typos and copy-paste bugs from the secure
  element handling code.

- Firmware download support for the pn544 driver. This chipset can enter a
  special mode where it's waiting for firmware blobs to replace the
  already flashed one. We now support that mode."

With repect to the ath tree, Kalle says:

"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.

For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."

I also pulled the wireless tree into wireless-next to support a
request from Johannes.  On top of all that, there are the usual
sort of driver updates.  The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.
