mac80211: fix WMM AP settings application
My
commit
77fdaa12cea26c204cc12c312fe40bc0f3dcdfd8
Author: Johannes Berg <johannes@sipsolutions.net>
Date: Tue Jul 7 03:45:17 2009 +0200
mac80211: rework MLME for multiple authentications
inadvertedly broke WMM because it removed, along with
a bunch of other now useless initialisations, the line
initialising sdata->u.mgd.wmm_last_param_set to -1
which would make it adopt any WMM parameter set. If,
as is usually the case, the AP uses WMM parameter set
sequence number zero, we'd never update it until the
AP changes the sequence number.
Add the missing initialisation back to get the WMM
settings from the AP applied locally.

mac80211: fix peer HT capabilities
I noticed yesterday, because Jeff had noticed
a speed regression, cf. bug
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
that the SM PS settings for peers were wrong.
Instead of overwriting the SM PS settings with
the local bits, we need to keep the remote bits.
The bug was part of the original HT code from
over two years ago, but unfortunately nobody
noticed that it makes no sense -- we shouldn't
be overwriting the peer's setting with our own
but rather keep it intact when masking the peer
capabilities with our own.
While fixing that, I noticed that the masking of
capabilities is completely useless for most of
the bits, so also fix those other bits.
Finally, I also noticed that PSMP_SUPPORT no
longer exists in the final 802.11n version, so
also remove that.

Libertas: fix buffer overflow in lbs_get_essid()
The libertas driver copies the SSID buffer back to the wireless core and
appends a trailing NULL character for termination. This is
a) unnecessary because the buffer is allocated with kzalloc and is hence
already NULLed when this function is called, and
b) for priv->curbssparams.ssid_len == 32, it writes back one byte too
much which causes memory corruptions.
Fix this by removing the extra write.

we see from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2125
that power saving does not work well on 3945. Since then power saving has
also been connected with association problems where an AP deathenticates a
3945 after it is unable to transmit data to it - this happens when 3945
enters power savings mode.
Disable power save support until issues are resolved.

iwlwifi: fix more eeprom endian bugs
I've also for a long time had a problem with the
temperature calculation code, which I had fixed
by byte-swapping the values, and now it turns out
that was the correct fix after all.
Also, any use of iwl_eeprom_query_addr() that is
for more than a u8 must be cast to little endian,
and some structs as well.
Fix all this. Again, no real impact on platforms
that already are little endian.

iwlwifi: fix EEPROM/OTP reading endian annotations and a bug
The construct "le16_to_cpu((__force __le16)(r >> 16))" has
always bothered me when looking through the iwlwifi code,
it shouldn't be necessary to __force anything, and before
this code, "r" was obtained with an ioread32, which swaps
each of the two u16 values in it properly when swapping the
entire u32 value. I've had arguments about this code with
people before, but always conceded they were right because
removing it only made things not work at all on big endian
platforms.
However, analysing a failure of the OTP reading code, I now
finally figured out what is going on, and why my intuition
about that code being wrong was right all along.
It turns out that the 'priv->eeprom' u8 array really wants
to have the data in it in little endian. So the force code
above and all really converts *to* little endian, not from
it. Cf., for instance, the function iwl_eeprom_query16() --
it reads two u8 values and combines them into a u16, in a
little-endian way. And considering it more, it makes sense
to have the eeprom array as on the device, after all not
all values really are 16-bit values, the MAC address for
instance is not.
Now, what this really means is that all the annotations are
completely wrong. The eeprom reading code should fill the
priv->eeprom array as a __le16 array, with __le16 values.
This also means that iwl_read_otp_word() should really have
a __le16 pointer as the data argument, since it should be
filling that in a format suitable for priv->eeprom.
Propagating these changes throughout, iwl_find_otp_image()
is found to be, now obviously visible, defective -- it uses
the data returned by iwl_read_otp_word() directly as if it
was CPU endianness. Fixing that, which is this hunk of the
patch:
- next_link_addr = link_value * sizeof(u16);
+ next_link_addr = le16_to_cpu(link_value) * sizeof(u16);
is the only real change of this patch. Everything else is
just fixing the sparse annotations.
Also, the bug only shows up on big endian platforms with a
1000 series card. 5000 and previous series do not use OTP,
and 6000 series has shadow RAM support which means we don't
ever use the defective code on any cards but 1000.

sizeof(iv16) and sizeof(iv32) are the sizes of pointers. Change them to
the size of the copied data.
Furthermore, iveiv_entry is a local structure that has just been
initialized and is not visible outside this function. Thus, there would
seem to be no point to copy data into it. The order of the arguments is
thus changed to copy the data into the parameters, which are provided as

iwlwifi: power up all devices for EEPROM read
Recent commits "iwlwifi: remove power-wasting calls to apm_ops.init()" and
"iwlagn: power up device before initializing EEPROM" had the goal of
reducing device power consumption from the time the module is loaded until
the interface is brought up and the device's power saving mechanisms kick
in. The idea is that once the module is loaded there is no need for the
device to consume power until the interface is brought up.
With the current solution the device is only powered up during EEPROM read,
and then so also only if the EEPROM type is OTP. We have found that on
certain platforms even non-OTP devices require power to be up during EEPROM
read. On these platforms the driver never loads and the system log contains
the following:
iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080403D8
We thus now power up all devices during EEPROM read.

packet: dont call sleeping functions while holding rcu_read_lock()

654d1f8a019dfa06d (packet: less dev_put() calls)

netfilter: fix crashes in bridge netfilter caused by fragment jumps
When fragments from bridge netfilter are passed to IPv4 or IPv6 conntrack
and a reassembly queue with the same fragment key already exists from
reassembling a similar packet received on a different device (f.i. with
multicasted fragments), the reassembled packet might continue on a different
codepath than where the head fragment originated. This can cause crashes
in bridge netfilter when a fragment received on a non-bridge device (and
thus with skb->nf_bridge == NULL) continues through the bridge netfilter
code.
Add a new reassembly identifier for packets originating from bridge
netfilter and use it to put those packets in insolated queues.

When we close a connection, on master server the connection became
CLOSE_WAIT/TIME_WAIT, it was synced to slaves, but if master is
finished within it's timeouts (CLOSE), it will not be synced to
slaves. Then slaves will be kept on CLOSE_WAIT/TIME_WAIT until
timeout reaches. Thus we should also sync with CLOSE.

A valid CAN dataframe can have a data length code (DLC) of 0 .. 8 data bytes.
When reading the CAN controllers register the 4-bit value may contain values

The ISO 11898-1 Chapter 8.4.2.3 (DLC field) says that register values > 8
should be reduced to 8 without any error reporting or frame drop.
This patch introduces a new helper macro to cast a given 4-bit data length

net: Fix userspace RTM_NEWLINK notifications.
I received some bug reports about userspace programs having problems
because after RTM_NEWLINK was received they could not immediate access
files under /proc/sys/net/ because they had not been registered yet.
The original problem was trivially fixed by moving the userspace
notification from rtnetlink_event() to the end of
register_netdevice().
When testing that change I discovered I was still getting RTM_NEWLINK
events before I could access proc and I was also getting RTM_NEWLINK
events after I was seeing RTM_DELLINK. Things practically guaranteed
to confuse userspace.
After a little more investigation these extra notifications proved to
be from the new notifiers NETDEV_POST_INIT and NETDEV_UNREGISTER_BATCH
hitting the default case in rtnetlink_event, and triggering
unnecessary RTM_NEWLINK messages.
rtnetlink_event now explicitly handles NETDEV_UNREGISTER_BATCH and
NETDEV_POST_INIT to avoid sending the incorrect userspace
notifications.

tty: split the lock up a bit further
The tty count sanity check may need the BKL, that isn't clear. However it
is clear that the count use of the lock is internal and independant of the
bigger use of the lock.
Furthermore the file list locking is also separately locked already

tty: moxa: split open lock
moxa_openlock is used for several situations where we want to handle the
case of an ioctl that crosses many ports (not just the open tty), and also
cases where an open races a deinit (eg a pci unplug) and we hangup a port
before we can cope with that.
The non open race cases can use the moxa_lock spinlock. This simplifies sorting
out the remaining mess.
