I've seen reports of invalid stats in /proc/net/dev for bonding
interfaces, and found it's a pretty easy problem to reproduce. Since
the current code zeros the bonding stats when a read is requested and a
pointer to that data is returned to the caller we cannot guarantee that
the caller has completely accessed the data before a successive call to
request the stats zeroes the stats again.
This patch creates a new stack variable to keep track of the updated
stats and copies the data from that variable into the bonding stats
structure. This ensures that the value for any of the bonding stats
should not incorrectly return zero for any of the bonding statistics.
This does use more stack space and require an extra memcpy, but it seems
like a fair trade-off for consistently correct bonding statistics.

This patch eliminates a problem (reported by lockdep) in the
bond_set_multicast_list function. It first reduces the locking on
bond->lock to a simple read_lock, and second, adds netif_tx locking
around the bonding mc_list manipulations that occur outside of the
set_multicast_list function.
The original problem was related to IPv6 addrconf activity.

Subject: [PATCH, REPOST] Fix/Rewrite of the mipsnet driver
Content-Type: text/plain; charset=us-ascii
Hello All,
currently the mipsnet driver fails after transmitting a number of
packages because SKBs are allocated but never freed. I fixed that
and coudn't refrain from removing the most egregious warts.
- mipsnet.h folded into mipsnet.c, as it doesn't provide any
useful external interface.
- Free SKB after transmission.
- Call free_irq in mipsnet_close, to balance the request_irq in
mipsnet_open.
- Removed duplicate read of rxDataCount.
- Some identifiers are now less verbose.
- Removed dead and/or unnecessarily complex code.
- Code formatting fixes.
Tested on Qemu's mipssim emulation, with this patch it can boot a
Debian NFSroot.

Resubmitting patch from Al Viro <viro@zeniv.linux.org.uk>, with subject -
[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.

macb devices are only found integrated on SoCs, so they can't be
hotplugged. Thus, the probe() and exit() functions can be __init and
__exit, respectively. By using platform_driver_probe() instead of
platform_driver_register(), there won't be any references to the
discarded probe() function after the driver has loaded.
This also fixes a section mismatch due to macb_probe(), defined as
__devinit, calling macb_get_hwaddr, defined as __init.

w/o the first change: if end == start you get MAX_JIFFY_OFFSET which
isn't what you want...
For the latter I think to be technically correct you need the +1 to
account for the jiffy between MAX_JIFFY_OFFSET and 0
(hmm w/ the 2nd change the first isn't strictly needed... ah well)

We must not transmit packets we're not able to encrypt.
This fixes a bug where in a tiny timeframe after machine resume
packets can get sent unencrypted and might leak information.
This also fixes three small resource leakages I spotted while fixing
the security problem. Properly deallocate the DMA slots in any DMA
allocation error path.

The problem is that priv->assoc_id is set when assoc. resp frame is
received. But, when it is set, LQ cmd is still not sent to the uCode, it is
done from bg_post_assoc, which is called through a workqueue.
On the other hand, when a tx arrives at the moment when this flag is set,
but LQ is still not sent, the if condition in tx_skb will not hold and
the frame will not be dropped. Thus, it will be sent through
which is still not in the sta table in the uCoded.

The geo/channel information is obtained from the EEPROM, which is read
during probe. We can thus set up channel information at this time. This
helps us to support ioctl commands that rely on this before the interface
is brought up.
Clearly matches _init_channel_map with _free_channel_map and _init_geos
with _free_geos to ensure functions calling these routines can also call
their cleanup routines.
Fixes a few bugs:
- if channel information is not available when ioctl commands are
issued then we get a NULL pointer oops. Having channel information
set up during probe we can deal with ioctl commands without requiring
interface to be brought up.
This fixes bug: http://www.bughost.org/bugzilla/show_bug.cgi?id=1552
- Fix potential problem if user triggers probe/remove/probe sequence. The
value of priv->channel_count was used to determine if channel map is
set up. This value was never reset when channel map was removed.
- Fix memory leak: priv->modes need to be freed when device removed.

This device is found on the 'Belkin Wireless G Desktop Card' product, model 'F5D7000uk'. From memory, the chip on the card is inscribed RTL8185L; (I don't know the significance of the 'L', I'm afraid).

This zeros out all microcode related memory before loading
the microcode.
This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.
This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.
While at it, fix naming of MACCTL values.

* remove debug level ATH5K_DEBUG_FATAL. doesn't make sense as a debug level -
if it's fatal it should be logged as an error.
* fancier printing of debug levels. cat /debugfs/ath5k/phy0/debug.
* allow debug levels to be changed by echoing their name into
/debugfs/ath5k/phy0/debug. this will toggle the state, when it was off it will
be turned on and vice versa.
* use copy_from_user() when reading from the debug files. use unsigned int for
better optimization. reduce buffer sizes on stack.

Both the old e1000 driver and the new e1000e driver can drive some
PCI-Express e1000 cards, and we should avoid ambiguity about which
driver will pick up the support for those cards when both drivers are
enabled.
This solves the problem by having the old driver support those cards if
the new driver isn't configured, but otherwise ceding support for PCI
Express versions of the e1000 chipset to the newer driver. Thus
allowing both legacy configurations where only the old driver is active
(and handles all chips it knows about) and the new configuration with
the new driver handling the more modern PCIE variants.

Auke & co have been appraised of the situation.

in "11.1.2.2 Beacon generation in an IBSS" the IEEE802.11 standard says, each
STA should... "b) Calculate a random delay uniformly distributed in the range
between zero and twice aCWmin × aSlotTime,".
configure cwmin and cwmax of the beacon queue in IBSS mode according to this.
unfortunately beacon backoff does not work reliably yet, so i suspect we have a
problem somewhere else, since the same settings (and similar beacon timer
configuration) work for madwifi.

use SWBA (software beacon alert) interrupts to keep track of the next beacon
time und check if a HW merge (automatic TSF update) has happened on every
received beacon with the same BSSID.
this is necessary because the atheros hardware will silently update the local
TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon
timers no beacons are sent until the timers wrap around (typically after about
1 minute).
this solution is not very nice, since we have to look into every beacon, but
there is apparently no other way to detect HW merges.

variety of situations. most important is the possibility to call it with the
timestamp of a received beacon, when we detected that a HW merge has happened
and we need to reconfigure the beacon timers based on that.
we call this from the mac80211 callback reset_tsf now instead of beacon_update,
and there will be more use of it in the next patch.
