This patch fixes the following inconsistencies in bond_release_all:
- IFF_BONDING flag is not stripped from slaves
- MTU is not restored
- no netdev notifiers are sent
Instead of trying to keep bond_release and bond_release_all in sync
I think we can re-use bond_release as the environment for calling it
is correct (RTNL is held). I have been running tests for the past
week and they came out successful. The only way for bond_release to fail
is for the slave to be attached in a different bond or to not be a slave
but that cannot happen as RTNL is held and no slave manipulations can be
achieved.
V2: As suggested bond_release is renamed to __bond_release_one with a
new parameter "all" introduced so to avoid calling unnecessary code while
destroying a bond, and a wrapper for it called bond_release is created
because of ndo_del_link. bond_release_all() is removed.

netbk_fatal_tx_err() calls xenvif_carrier_off(), which does
a xenvif_put(). As callers of netbk_fatal_tx_err should only
have one reference to the vif at this time, then the xenvif_put
in netbk_fatal_tx_err is one too many.

Check whether the phy-reset GPIO is valid, prior to requesting it.
In the case a board does not provide a phy-reset GPIO, just returns immediately.
With such gpio validation in place, it is also safe to change from pr_debug to
dev_err in the case the gpio request fails.

The 3ad machine state spinlock can be used before it is inititialized
while doing bond_enslave() (and the port is being initialized) since
port->slave is set before the lock is prepared, thus causing soft

bond_3ad_update_lacp_rate()
port->slave can be NULL since it's being initialized in bond_enslave
thus dereferencing a NULL pointer in bond_3ad_update_lacp_rate()
Also fix a minor bug, which could cause a port not to have
AD_STATE_LACP_TIMEOUT since there's no sync between
bond_3ad_update_lacp_rate() and bond_3ad_bind_slave(), by changing

Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G
were due to overflow of the RX DMA ring buffer, which was created with 64
slots. That finding reminded me that I was seeing similar crashed on a netbook,
which also has a relatively slow processor. After increasing the number of
slots to 128, runs on the netbook that previously failed now worked; however,
I found that 109 slots had been used in one test. For that reason, the number
of slots is being increased to 256.

separately
rtlwifi allocates both setup_packet and data buffer of control message urb,
using shared kmalloc in _usbctrl_vendorreq_async_write. Structure used for
allocating is:
struct {
u8 data[254];
struct usb_ctrlrequest dr;
};
Because 'struct usb_ctrlrequest' is __packed, setup packet is unaligned and
DMA mapping of both 'data' and 'dr' confuses ARM/sunxi, leading to memory
corruptions and freezes.
Patch changes setup packet to be allocated separately.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
This probably is the last big pull request for wireless bits
for 3.9. Of course, I'm sure there will be a few stragglers here
and there...surely a few bug fixes as well... :-) (In fact, I see
that Johannes has already queued-up a few more for me while I was
preparing this...)
Included are a number of pulls...
For mac80211-next, Johannes says:
"The biggest change I have is undoubtedly Marco's mesh powersave
implementation. Beyond that, I have a patch from Emmanuel to modify the
DTIM period API in mac80211, scan improvements and a removal of some
previous workaround code from Stanislaw, dynamic short slot time from
Thomas and 64-bit station byte counters from Vladimir. I also made a
number of changes myself, some related to WoWLAN, some auth/deauth
improvements and most of them BSS list cleanups."
"This time, I have relatively large number of fixes in various areas of
the code (a memory leak in regulatory, an RX race in mac80211, the new
radar checking caused a P2P device problem, some mesh issues with
stations, an older bug in tracing and for kernel-doc) as well as a
number of small new features. The biggest (in the diffstat) is my work
on hidden SSID tracking."
"Please pull to get
* radar detection work from Simon
* mesh improvements from Thomas
* a connection monitoring/powersave fix from Wojciech
* TDLS-related station management work from Jouni
* VLAN crypto fixes from Michael Braun
* CCK support in minstrel_ht from Felix
* an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel)
* some WoWLAN work from Amitkumar Karwar: pattern match offset and a
documentation fix
* some WoWLAN work from myself (TCP connection wakeup feature API)
* and a lot of VHT (and some HT) work (also from myself)
And a number of more random cleanups/fixes. I merged mac80211/master to
avoid a merge problem there."
And regarding iwlwifi-next, Johannes says:
"We continue work on our new driver, but I also have a WoWLAN and AP mode
improvement for the previous driver and a change to use threaded
interrupts to prepare us for working with non-PCIe devices."
Regarding wl12xx, Luca says:
"A few more patches intended for 3.9. Mostly some clean-ups I've been
doing to make it easier to support device-tree. Also including one bug
fix for wl12xx where the rates we advertise were wrong and an update in
the wlconf structure to support newer firmwares."
For the nfc-next bits, Samuel says:
"This is the second NFC pull request for 3.9.
We have:
- A few pn533 fixes on top of Waldemar refactorization of the driver, one of
them fixes target mode.
- A new driver for Inside Secure microread chipset. It supports two
physical layers: i2c and MEI. The MEI one depends on a patchset that's
been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The
dependency is a KConfig one which means this code is not buildable as long
as the MEI API is not usptream."
"This 3rd NFC pull request for 3.9 contains a fix for the microread MEI
physical layer support, as the MEI bus API changed.
From the MEI code, we now pass the MEI id back to the driver probe routine,
and we also pass a name and a MEI id table through the mei_bus_driver
structure. A few renames as well like e.g. mei_bus_driver to mei_driver or
mei_bus_client to mei_device in order to be closer to the driver model
practices."
For the ath6kl bits, Kalle says:
"There's not anything special here, most of the patches are just code
cleanup. The only functional changes are using the beacon interval from user
space and fixing a crash which happens when inserting and removing the
module in a loop."
Also, I pulled the wireless tree in order to resolve some pending
merge issues. On top of that, there is a bunch of work on brcmfmac
that leads up to P2P support. Also, mwifiex, rtlwifi, and a variety
of other drivers see some basic cleanups and minor enhancements.
Please let me know if there are problems!

The reason is a problem with asynchronous vs. synchronous
commands, what happens here is the following:
* TE 0x2601 is removed, the TIME_EVENT_CMD for that is async
* a new TE (will be 0x2701) is created, the TIME_EVENT_CMD
for that is sync and also uses a notification wait for the
response (to avoid another race condition)
* the response for the TE 0x2601 removal comes from the
firmware, and is handled by the notification wait handler
that's really waiting for the second response, but can't
tell the difference, we therefore see the message
"TIME_EVENT_CMD response - UID = 0x2601" instead of
"TIME_EVENT_CMD response - UID = 0x2701".
Fix this issue by making the TE removal synchronous as well,
this means that we wait for the response to that command
first, before there's any chance of sending a new one.
Also, to detect such issues more easily in the future, add
a warning to the notification handler that detects them.

Upper case macros for various chip attributes are slightly
difficult to read and are a bit out of characterto the other
tg3_<foo> attribute functions.
Convert:
GET_ASIC_REV(tp->pci_chip_rev_id) -> tg3_asic_rev(tp)
GET_CHIP_REV(tp->pci_chip_rev_id) -> tg3_chip_rev(tp)
Remove:
GET_METAL_REV(tp->pci_chip_rev_id) -> tg3_metal_rev(tp) (unused)
Add:
tg3_chip_rev_id(tp) for tp->pci_chip_rev_id so access styles
are similar to tg3_asic_rev and tg3_chip_rev.
These macros are not converted to static inline functions
because gcc (tested with 4.7.2) is currently unable to
optimize the object code it produces the same way and code
is otherwise larger.
