commit 1f8c5cecfe
Author: Heiko Stuebner <heiko@sntech.de>
Date:   Wed Feb 1 10:33:01 2012 -0800

    Input: evdev - fix variable initialisation

    Commit 509f87c5f564 (evdev - do not block waiting for an event if
    fd
    is nonblock) created a code path were it was possible to use retval
    uninitialized.

    This could lead to the xorg evdev input driver getting corrupt data
    and refusing to work with log messages like
    	AUO-Pixcir touchscreen: Read error: Success
    	sg060_keys: Read error: Success
    	AUO-Pixcir touchscreen: Read error: Success
    	sg060_keys: Read error: Success
    (for drivers auo-pixcir-ts and gpio-keys).

commit 4dc43d7079
Author: Arve Hjønnevåg <arve@android.com>
Date:   Fri Oct 17 15:20:55 2008 -0700

    Input: evdev - Add ioctl to block suspend while event queue is not empty.

    Add an ioctl, EVIOCSSUSPENDBLOCK, to enable a wakelock that will block
    suspend while the event queue is not empty. This allows userspace code to
    process input events while the device appears to be asleep.

    The current code holds the wakelock for up 5 seconds for every input
    device and client. This can prevent suspend if sensor with a high data
    rate is active, even when that sensor is not capable of waking the
    device once it is suspended.

Author: Arve Hjønnevåg <arve@android.com>
Date:   Mon Jan 23 17:15:45 2012 -0800

    Input: evdev - Don't hold wakelock when no data is available to user-space

    If there is no SYN_REPORT event in the buffer the buffer data is invisible
    to user-space. The wakelock should not be held in this case.

    usb: gadget: android: Honor CONFIG_USB_GADGET_VBUS_DRAW

    The maximum current draw was hard coded to 500 mA.  composite.c
    has code that uses CONFIG_USB_GADGET_VBUS_DRAW to set the
    bMaxPower and to set whether or not the device is self-powered if
    they haven't been set.  This change removes the code in android.c
    to allow composite.c to set them.

    rtc: Fix some bugs that allowed accumulating time drift in suspend/resume

    The current code checks if abs(delta_delta.tv_sec) is greater or
    equal to two before it discards the old delta value, but this can
    trigger at close to -1 seconds since -1.000000001 seconds is stored
    as tv_sec -2 and tv_nsec 999999999 in a normalized timespec.

    rtc_resume had an early return check if the rtc value had not changed
    since rtc_suspend. This effectivly stops time for the duration of the
    short sleep. Check if sleep_time is positive after all the adjustments
    have been applied instead since this allows the old_system adjustment
    in rtc_suspend to have an effect even for short sleep cycles.

    rtc: Avoid accumulating time drift in suspend/resume

    Because the RTC interface is only a second granular interface,
    each time we read from the RTC for suspend/resume, we introduce a
    half second (on average) of error.

    In order to avoid this error accumulating as the system is suspended
    over and over, this patch measures the time delta between the RTC
    and the system CLOCK_REALTIME.

    If the delta is less then 2 seconds from the last suspend, we compensate
    by using the previous time delta (keeping it close). If it is larger
    then 2 seconds, we assume the clock was set or has been changed, so we
    do no correction and update the delta.

    Note: If NTP is running, ths could seem to "fight" with the NTP corrected
    time, where as if the system time was off by 1 second, and NTP slewed the
    value in, a suspend/resume cycle could undo this correction, by trying to
    restore the previous offset from the RTC. However, without this patch,
    since each read could cause almost a full second worth of error, its
    possible to get almost 2 seconds of error just from the suspend/resume
    cycle alone, so this about equal to any offset added by the compensation.

    Further on systems that suspend/resume frequently, this should keep time
    closer then NTP could compensate for if the errors were allowed to
    accumulate.

    Credits to Arve Hjønnevåg for suggesting this solution.

    This patch also improves some of the variable names and adds more clear
    comments.

7878aa18cb cfg80211: Remove strict validation of AKM suites
NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or
the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor
specific AKMs could be used. The current validation code for the connect
command prevents cfg80211-based drivers from using these mechanisms even
if the driver would not actually use this AKM value (i.e., it uses
WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be
used since this value is not used there.

Remove the unnecessary validation step in cfg80211 to allow drivers to
decide what AKMs are supported. In theory, we could handle this by
advertising supported AKMs, but that would not be very effective unless
we enforce all drivers (including mac80211) to advertise the set of
supported AKMs. This would require additional changes in many places
whenever a new AKM is introduced even though no actually functionality
changes may be required in most drivers.

commit 0bac71af6e66dc798bf07d0c0dd14ee5503362f9 upstream.

Johannes' patch for "cfg80211: fix regulatory NULL dereference"
broke user regulaotry hints and it did not address the fact that
last_request was left populated even if the previous regulatory
hint was stale due to the wiphy disappearing.

Fix user reguluatory hints by only bailing out if for those
regulatory hints where a request_wiphy is expected. The stale last_request
considerations are addressed through the previous fixes on last_request
where we reset the last_request to a static world regdom request upon
reset_regdomains(). In this case though we further enhance the effect
by simply restoring reguluatory settings completely.

3ed26be173 cfg80211: fix race on init and driver registration
commit a042994dd377d86bff9446ee76151ceb6267c9ba upstream.

There is a theoretical race that if hit will trigger
a crash. The race is between when we issue the first
regulatory hint, regulatory_hint_core(), gets processed
by the workqueue and between when the first device
gets registered to the wireless core. This is not easy
to reproduce but it was easy to do so through the
regulatory simulator I have been working on. This
is a port of the fix I implemented there [1].

By the time userspace returns with a response to
the regulatory domain request, the wiphy causing
the request might have gone away. If this is so,
reject the update but mark the request as having
been processed anyway.

5c02e3ae0a cfg80211: fix bug on regulatory core exit on access to last_request
commit 58ebacc66bd11be2327edcefc79de94bd6f5bb4a upstream.

Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added
the .uevent() callback for the regulatory device used during
the platform device registration. The change was done to account
for queuing up udev change requests through udevadm triggers.
The change also meant that upon regulatory core exit we will now
send a uevent() but the uevent() callback, reg_device_uevent(),
also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.

This fix is required for kernels >= v2.6.39

$ git describe --contains 4d9d88d1
v2.6.39-rc1~468^2~25^2^2~21

The impact of not having this present is that a bogus paging
access may occur (only read) upon cfg80211 unload time. You
may also get this BUG complaint below. Although Johannes
could not reproduce the issue this fix is theoretically correct.

508ed74454 cfg80211: Fix validation of AKM suites
commit 1b9ca0272ffae212e726380f66777b30a56ed7a5 upstream.

Incorrect variable was used in validating the akm_suites array from
NL80211_ATTR_AKM_SUITES. In addition, there was no explicit
validation of the array length (we only have room for
NL80211_MAX_NR_AKM_SUITES).

This can result in a buffer write overflow for stack variables with
arbitrary data from user space. The nl80211 commands using the affected
functionality require GENL_ADMIN_PERM, so this is only exposed to admin
users.

cb49a34465 wireless: Reset beacon_found while updating regulatory
commit aa3d7eef398dd4f29045e9889b817d5161afe03e upstream.

During the association, the regulatory is updated by country IE
that reaps the previously found beacons. The impact is that
after a STA disconnects *or* when for any reason a regulatory
domain change happens the beacon hint flag is not cleared
therefore preventing future beacon hints to be learned.
This is important as a regulatory domain change or a restore
of regulatory settings would set back the passive scan and no-ibss
flags on the channel. This is the right place to do this given that
it covers any regulatory domain change.

When one of the SSID's length passed in a scan or sched_scan request
is larger than 255, there will be an overflow in the u8 that is used

Fix this by checking the nl80211 attribute length before copying it to

ed9d01026f cfg80211: Use consistent BSS matching between scan and sme
cfg80211 scan code adds separate BSS entries if the same BSS shows up

Please note that drivers using cfg80211_roamed() need to be modified to
fully implement this fix. This commit includes only minimal changes to
avoid compilation issues; it maintains the old (broken) behavior for
most drivers. ath6kl was the only one that I could test, so I updated

7527a782e1 cfg80211: advertise possible interface combinations
Add the ability to advertise interface combinations in nl80211.
This allows the driver to indicate what the combinations are
that it supports. "Combinations" of just a single interface are
implicit, as previously. Note that cfg80211 will enforce that
the restrictions are met, but not for all drivers yet (once all
drivers are updated, we can remove the flag and enforce for all).

When no combinations are actually supported, an empty list will
be exported so that userspace can know if the kernel exported
this info or not (although it isn't clear to me what tools using
the info should do if the kernel didn't export it).

Since some interface types are purely virtual/software and don't
fit the restrictions, those are exposed in a new list of pure SW
types, not subject to restrictions. This mainly exists to handle
AP-VLAN and monitor interfaces in mac80211.

necessary cleanup but would not call the driver.  This was enough to
prevent the bounce back between the driver and mac80211, but not
between mac80211 and cfg80211.

To fix this, we now do the cleanup in mac80211 before calling
cfg80211.  To help with locking issues, the workqueue was moved from
cfg80211 to mac80211.

56d1893d94 cfg80211: restrict AP beacon intervals
Multiple virtual AP interfaces can currently try
to use different beacon intervals, but that just
leads to problems since it won't actually be done
that way by drivers. Return an error in this case
to make sure it won't be done wrong.

Also, ignore attempts to change the DTIM period
or beacon interval during the lifetime of the BSS.

bbe6ad6dcb cfg80211/nl80211: add interval attribute for scheduled scans
Introduce NL80211_ATTR_SCHED_SCAN_INTERVAL as a required attribute for
NL80211_CMD_START_SCHED_SCAN.  This value informs the driver at which
intervals the scheduled scan cycles should be executed.

807f8a8c30 cfg80211/nl80211: add support for scheduled scans
Implement new functionality for scheduled scan offload.  With this feature we
can scan automatically at certain intervals.

The idea is that the hardware can perform scan automatically and filter on
desired results without waking up the host unnecessarily.

Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN
commands to the nl80211 interface.  When results are available they are
reported by NL80211_CMD_SCHED_SCAN_RESULTS events.  The userspace is
informed when the scheduled scan has stopped with a
NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by
the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.

0a35d36d6f cfg80211: Use capability info to detect mesh beacons.
Mesh beacons no longer use all-zeroes BSSID.  Beacon frames for MBSS,
infrastructure BSS, or IBSS are differentiated by the Capability
Information field in the Beacon frame.  A mesh STA sets the ESS and IBSS
subfields to 0 in transmitted Beacon or Probe Response management
frames.

b130e5cec9 nl80211: Introduce NL80211_MESH_SETUP_USERSPACE_AMPE
Introduce a new configuration option to support AMPE from userspace.

Prior to this series we only supported authentication in userspace: an
authentication daemon would authenticate peer candidates in userspace
and hand them over to the kernel.  From that point the mesh stack would
take over and establish a peer link (Mesh Peering Management).

These patches introduce support for Authenticated Mesh Peering Exchange
in userspace.  The userspace daemon implements the AMPE protocol and on
successfull completion create mesh peers and install encryption keys.
