    batman-adv: unify hash_entry field position in tt_local/global_entry
    
    commit 93840ac40bb0d0f177ef8af74e64671be67e8c37 upstream.
    
    Function tt_response_fill_table() actually uses a tt_local_entry pointer to
    iterate either over the local or the global table entries (it depends on the
    what hash table is passed as argument). To iterate over such entries the
    hlist_for_each_entry_rcu() macro has to access their "hash_entry" field which
    MUST be at the same position in both the tt_global/local_entry structures.

    commit 9d8523931f7f5eb8900077f0da0fbe6b8ad0010b upstream.
    
    In the TT_RESPONSE packet, the number of carried entries is not correctly set.
    This leads to a wrong interpretation of the packet payload on the receiver side
    causing random entries to be added to the global translation table. Therefore
    the latter gets always corrupted, triggering a table recovery all the time.

    Currently the counter of tt_local_entry structures (tt_local_num) is incremented
    each time the tt_local_reset_flags() is invoked causing the node to send wrong
    TT_REPONSE packets containing a copy of non-initialised memory thus corrupting

    USB: EHCI: fix HUB TT scheduling issue with iso transfer
    
    commit 811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream.
    
    The current TT scheduling doesn't allow to play and then record on a
    full-speed device connected to a high speed hub.
    
    The IN iso stream can only start on the first uframe (0-2 for a 165 us)
    because of CSPLIT transactions.
    For the OUT iso stream there no such restriction. uframe 0-5 are possible.
    
    The idea of this patch is that the first uframe are precious (for IN TT iso
    stream) and we should allocate the last uframes first if possible.
    
    For that we reverse the order of uframe allocation (last uframe first).
    
    Here an example :
    
    hid interrupt stream
    ----------------------------------------------------------------------
    uframe                |  0  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |
    ----------------------------------------------------------------------
    max_tt_usecs          | 125 | 125 | 125 | 125 | 125 | 125 | 30  |  0  |
    ----------------------------------------------------------------------
    used usecs on a frame | 13  |  0  |  0  |  0  |  0  |  0  |  0  |  0  |
    ----------------------------------------------------------------------
    
    iso OUT stream
    ----------------------------------------------------------------------
    uframe                |  0  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |
    ----------------------------------------------------------------------
    max_tt_usecs          | 125 | 125 | 125 | 125 | 125 | 125 | 30  |  0  |
    ----------------------------------------------------------------------
    used usecs on a frame | 13  | 125 |  39 |  0  |  0  |  0  |  0  |  0  |
    ----------------------------------------------------------------------
    
    There no place for iso IN stream  (uframe 0-2 are used) and we got "cannot
    submit datapipe for urb 0, error -28: not enough bandwidth" error.
    
    With the patch this become.
    
    iso OUT stream
    ----------------------------------------------------------------------
    uframe                |  0  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |
    ----------------------------------------------------------------------

    usb-storage: Accept 8020i-protocol commands longer than 12 bytes
    
    commit 2f640bf4c94324aeaa1b6385c10aab8c5ad1e1cf upstream.
    
    The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands;
    shorter commands must be padded.  Simon Detheridge reports that his
    3-TB USB disk drive claims to use the 8020i protocol (which is
    normally meant for ATAPI devices like CD drives), and because of its
    large size, the disk drive requires the use of 16-byte commands.
    However the usb_stor_pad12_command() routine in usb-storage always
    sets the command length to 12, making the drive impossible to use.
    
    Since the SFF-8020i specification allows for 16-byte commands in
    future extensions, we may as well accept them.  This patch (as1490)
    changes usb_stor_pad12_command() to leave commands larger than 12
    bytes alone rather than truncating them.

    USB: Fix Corruption issue in USB ftdi driver ftdi_sio.c
    
    commit b1ffb4c851f185e9051ba837c16d9b84ef688d26 upstream.
    
    Fix for ftdi_set_termios() glitching output
    
    ftdi_set_termios() is constantly setting the baud rate, data bits and parity
    unnecessarily on every call, . When called while characters are being
    transmitted can cause the FTDI chip to corrupt the serial port bit stream
    output by stalling the output half a bit during the output of a character.
    Simple fix by skipping this setting if the baud rate/data bits/parity are
    unchanged.

    USB: workaround for bug in old version of GCC
    
    commit 97ff22ee3b4cb3a334f7385e269773141aed702f upstream.
    
    This patch (as1491) works around a bug in GCC-3.4.6, which is still
    supposed to be supported.  The number of microseconds in the udelay()
    call in quirk_usb_disable_ehci() is fixed at 100, but the compiler
    doesn't understand this and generates a link-time error.  So we
    replace the otherwise unused variable "delta" with a simple constant
    100.  This same pattern is already used in other delay loops in that
    source file.

    USB: cdc-acm: Fix disconnect() vs close() race
    
    commit 5dc2470c602da8851907ec18942cd876c3b4ecc1 upstream.
    
    There's a race between the USB disconnect handler and the TTY close
    handler which may cause the acm object to be freed while it's still
    being used. This may lead to things like
    
    http://article.gmane.org/gmane.linux.usb.general/54250
    
    and
    
    https://lkml.org/lkml/2011/5/29/64
    
    This is the simplest fix I could come up with. Holding on to open_mutex
    while closing the TTY device prevents acm_disconnect() from freeing the
    acm object between acm->port.count drops to 0 and the TTY side of the
    cleanups are finalized.

    I get report from customer that his usb-serial

    The usb-serial converter's id:
    vendor_id product_id

    Then I search the usb-serial codes, and there are

    and ch341, commit 026dfaf1 cause it. Through many
    times to test, ch341 works well with this device,
    and pl2303 doesn't work quite often(it just work quite little).
    
    ch341 works well with this device, so we doesn't
    need pl2303 to support.I try to revert 026dfaf1 first,
    but it failed. So I prepare this patch by hand to revert it.

    USB: XHCI: resume root hubs when the controller resumes
    
    commit f69e3120df82391a0ee8118e0a156239a06b2afb upstream.
    
    This patch (as1494) fixes a problem in xhci-hcd's resume routine.
    When the controller is runtime-resumed, this can only mean that one of
    the two root hubs has made a wakeup request and therefore needs to be
    resumed as well.  Rather than try to determine which root hub requires
    attention (which might be difficult in the case where a new
    non-SuperSpeed device has been plugged in), the patch simply resumes
    both root hubs.
    
    Without this change, there is a race: The controller might be put back
    to sleep before it can activate its IRQ line, and the wakeup condition
    might never get handled.
    
    The patch also simplifies the logic in xhci_resume a little, combining
    some repeated flag settings into a single pair of statements.

    usb, xhci: fix lockdep warning on endpoint timeout
    
    commit f43d623164022dcbf6750ef220b7a1133a1183eb upstream.
    
    While debugging a usb3 problem, I stumbled upon this lockdep warning.

    Basically what is happening is in xhci_stop_endpoint_command_watchdog()
    the xhci->lock is grabbed with just spin_lock.  What lockdep deduces is
    that if an interrupt occurred while in this function it would deadlock
    with xhci_irq because that function also grabs the xhci->lock.
    
    Fixing it is trivial by using spin_lock_irqsave instead.
    
    This should be queued to stable kernels as far back as 2.6.33.

    usb, xhci: Clear warm reset change event during init
    
    commit 79c3dd8150fd5236d95766a9e662e3e932b462c9 upstream.
    
    I noticed on my Panther Point system that I wasn't getting hotplug events
    for my usb3.0 disk on a usb3 port.  I tracked it down to the fact that the
    system had the warm reset change bit still set.  This seemed to block future
    events from being received, including a hotplug event.
    
    Clearing this bit during initialization allowed the hotplug event to be
    received and the disk to be recognized correctly.
    
    This patch should be backported to kernels as old as 2.6.39.

    xhci: Set slot and ep0 flags for address command.
    
    commit d31c285b3a71cf9056e6a060de41f37780b0af86 upstream.
    
    Matt's AsMedia xHCI host controller was responding with a Context Error
    to an address device command after a configured device reset.  Some
    sequence of events leads both the slot and endpoint zero add flags
    cleared to zero, which the AsMedia host doesn't like:

    [  223.701992] xhci_hcd 0000:03:00.0: Setup ERROR: address device command for slot 1.
    
    The xHCI spec says that both flags must be set to one for the Address
    Device command.  When the device is first enumerated,
    xhci_setup_addressable_virt_dev() does set those flags.  However, when
    the device is addressed after it has been reset in the configured state,
    xhci_setup_addressable_virt_dev() is not called, and
    xhci_copy_ep0_dequeue_into_input_ctx() is called instead.  That function
    relies on the flags being set up by previous commands, which apparently
    isn't a good assumption.
    
    Move the setting of the flags into the common parent function.
    
    This should be queued for stable kernels as old as 2.6.35, since that
    was the first introduction of xhci_copy_ep0_dequeue_into_input_ctx.

    nfs: when attempting to open a directory, fall back on normal lookup (try #5)
    
    commit 1788ea6e3b2a58cf4fb00206e362d9caff8d86a7 upstream.
    
    commit d953126 changed how nfs_atomic_lookup handles an -EISDIR return
    from an OPEN call. Prior to that patch, that caused the client to fall
    back to doing a normal lookup. When that patch went in, the code began
    returning that error to userspace. The d_revalidate codepath however
    never had the corresponding change, so it was still possible to end up
    with a NULL ctx->state pointer after that.
    
    That patch caused a regression. When we attempt to open a directory that
    does not have a cached dentry, that open now errors out with EISDIR. If
    you attempt the same open with a cached dentry, it will succeed.
    
    Fix this by reverting the change in nfs_atomic_lookup and allowing
    attempts to open directories to fall back to a normal lookup
    
    Also, add a NFSv4-specific f_ops->open routine that just returns
    -ENOTDIR. This should never be called if things are working properly,
    but if it ever is, then the dprintk may help in debugging.
    
    To facilitate this, a new file_operations field is also added to the
    nfs_rpc_ops struct.

    TTY: ldisc, wait for ldisc infinitely in hangup
    
    commit 0c73c08ec73dbe080b9ec56696ee21d32754d918 upstream.
    
    For /dev/console case, we do not kill all ldisc users. It's due to
    redirected_tty_write test in __tty_hangup. In that case there still
    might be a process waiting e.g. in n_tty_read for input.
    
    We wait for such processes to disappear. The problem is that we use a
    timeout. After this timeout, we continue closing the ldisc and start
    freeing tty resources. It obviously leads to crashes when the other
    process is woken.
    
    So to fix this, we wait infinitely before reiniting the ldisc. (The
    tiocsetd remains untouched -- times out after 5s.)
    
    This is nicely reproducible with this run from shell:
      exec 0<>/dev/console 1<>/dev/console 2<>/dev/console
    and stopping a getty like:
      systemctl stop serial-getty@ttyS0.service
    
    The crash proper may be produced only under load or with constified
    timing the same as for 92f6fa09b.

    It is the only place where reinit is called from. And we really need
    to wait for the old ldisc to go once. Actually this is the place where
    the waiting originally was (before removed and re-added later).

    tty: hvc_dcc: Fix duplicate character inputs
    
    commit c2a3e84f950e7ddba1f3914b005861d46ae60359 upstream.
    
    Reading from the DCC grabs a character from the buffer and
    clears the status bit. Since this is a context-changing
    operation, instructions following the character read that rely on
    the status bit being accurate need to be synchronized with an
    ISB.
    
    In this case, the status bit check needs to execute after the
    character read otherwise we run the risk of reading the character
    and checking the status bit before the read can clear the status
    bit in the first place. When this happens, the user will see the
    same character they typed twice, instead of once.
    
    Add an ISB after the read and the write, so that the status check
    is synchronized with the read/write operations.

    pch_uart: Fix DMA resource leak issue
    
    commit 90f04c2926cfb5bf74533b0a7766bc896f6a0c0e upstream.
    
    Changing UART mode PIO->DMA->PIO->DMA like below, pch_uart driver can't get
    DMA channel resource.
    
    setserial /dev/ttyPCH0 ^low_latency
    setserial /dev/ttyPCH0 low_latency
    
    CAUSE:
    Changing mode using setserial command, ".startup" function which gets DMA
    channel is called before ".verify_port" function which sets
    dma-flag(use_dma/use_dma_flag) as 1.
    
    PIO->DMA
      .startup: Since dma-flag is 0, DMA channel is not requested.
      .verify_port: dma-flag is set as 1.
      .shutdown: N/A
    
    DMA->PIO
      .startup: Since dma-flag is 1, DMA channel is requested.
      .verify_port: dma-flag is set as 0.
      .shutdown: Since dma-flag is 0, DMA channel is not released.
    
    This means DMA channel resource leak occurs.
    Next time, this driver can't get DMA channel resource forever.
    
    MODIFICATION:
      Currently, when release DMA channel resource, this driver checks dma-flag.
      However, this specification occurs the above issue.
      This driver must check whether dma_request_channel is executed or not.
      The values are saved in private data variable "chan_tx/chan_tx".
      These variables mean if the value is NULL, DMA channel is not requested,
      if not NULL, DMA channel is requested.
    
    This patch fixes the issue.

    ISSUE:

    CAUSE:
    ML7831 and EG20T have the same register map for MAC address access.

    PM / driver core: disable device's runtime PM during shutdown
    
    commit af8db1508f2c9f3b6e633e2d2d906c6557c617f9 upstream.
    
    There may be an issue when the user issue "reboot/shutdown" command, then
    the device has shut down its hardware, after that, this runtime-pm featured
    device's driver will probably be scheduled to do its suspend routine,
    and at its suspend routine, it may access hardware, but the device has
    already shutdown physically, then the system hang may be occurred.
    
    I ran out this issue using an auto-suspend supported USB devices, like
    3G modem, keyboard. The usb runtime suspend routine may be scheduled
    after the usb controller has been shut down, and the usb runtime suspend
    routine will try to suspend its roothub(controller), it will access
    register, then the system hang occurs as the controller is shutdown.

    ip6_tunnel: copy parms.name after register_netdevice
    
    commit 731abb9cb27aef6013ce60808a04e04a545f3f4e upstream.
    
    Commit 1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create
    because register_netdevice will now create a valid name.  This works for the
    net_device itself.
    
    However the tunnel keeps a copy of the name in the parms structure for the
    ip6_tnl associated with the tunnel.  parms.name is set by copying the net_device
    name in ip6_tnl_dev_init_gen.  That function is called from ip6_tnl_dev_init in
    ip6_tnl_create, but it is done before register_netdevice is called so the name
    is set to a bogus value in the parms.name structure.
    
    This shows up if you do a simple tunnel add, followed by a tunnel show:
    
    [root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200
    [root@localhost ~]# ip -6 tunnel show
    ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000)
    ip6tnl%d: ipv6/ipv6 remote fec0::100 local fec0::200 encaplimit 4 hoplimit 64 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000)
    [root@localhost ~]#
    
    Fix this by moving the strcpy out of ip6_tnl_dev_init_gen, and calling it after
    register_netdevice has successfully returned.

    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.

    nl80211: fix HT capability attribute validation
    
    commit 6c7394197af90f6a332180e33f5d025d3037d883 upstream.
    
    Since the NL80211_ATTR_HT_CAPABILITY attribute is
    used as a struct, it needs a minimum, not maximum
    length. Enforce that properly. Not doing so could
    potentially lead to reading after the buffer.

    mac80211: fix NULL dereference in radiotap code
    
    commit f8d1ccf15568268c76f913b45ecdd33134387f1a upstream.
    
    When receiving failed PLCP frames is enabled, there
    won't be a rate pointer when we add the radiotap
    header and thus the kernel will crash. Fix this by
    not assuming the rate pointer is always valid. It's
    still always valid for frames that have good PLCP
    though, and that is checked & enforced.
    
    This was broken by my

    rt2x00: Fix sleep-while-atomic bug in powersaving code.
    
    commit ed66ba472a742cd8df37d7072804b2111cdb1014 upstream.
    
    The generic powersaving code that determines after reception of a frame
    whether the device should go back to sleep or whether is could stay
    awake was calling rt2x00lib_config directly from RX tasklet context.
    On a number of the devices this call can actually sleep, due to having
    to confirm that the sleeping commands have been executed successfully.
    
    Fix this by moving the call to rt2x00lib_config to a workqueue call.
    
    This fixes bug https://bugzilla.redhat.com/show_bug.cgi?id=731672

    If we hit the default case in the switch in if_spi_host_to_card() we'll leak
    the memory we allocated for 'packet'. This patch resolves the leak by freeing
    the allocated memory in that case.

    KVM: s390: Fix RUNNING flag misinterpretation
    
    commit 9e6dabeffd1d0ec2aa19aa076c4886067238d442 upstream.
    
    CPUSTAT_RUNNING was implemented signifying that a vcpu is not stopped.
    This is not, however, what the architecture says: RUNNING should be
    set when the host is acting on the behalf of the guest operating
    system.
    
    CPUSTAT_RUNNING has been changed to be set in kvm_arch_vcpu_load()
    and to be unset in kvm_arch_vcpu_put().
    
    For signifying stopped state of a vcpu, a host-controlled bit has
    been used and is set/unset basically on the reverse as the old
    CPUSTAT_RUNNING bit (including pushing it down into stop handling
    proper in handle_stop()).

    aacraid: controller hangs if kernel uses non-default ASPM policy
    
    commit cf16123c9c8e346ed1dd171295a678d77648d7f8 upstream.
    
    Aacraid controller can hang on some nodes if kernel uses non-default
    (powersave) ASPM policy.  Controller hangs shortly after successful load and
    hardware detection. Scsi error handler detects this hang and tries to restart
    hardware but it does not help.
    
    Initially it was noticed on RHEL6-based openVZ kernel after backporting
    aacraid driver from mainline (RHEL6 kernel with original driver works well)
    http://bugzilla.openvz.org/show_bug.cgi?id=2043
    
    This issue happens because default ASPM policy was changed in Red Hat
    kernels. Therefore guys from Red Hat have noticed this problem long time ago:
    on Fedora 12
     https://bugzilla.redhat.com/show_bug.cgi?id=540478
    on Fedora 14
     https://bugzilla.redhat.com/show_bug.cgi?id=679385
    
    In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In
    kernel changelog I've found that seems it was done by Matthew Garrett: -
    [scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735]
    
    However seems this patch was not submitted to mainline. I've reproduced this
    issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option,
    So I believe it makes sense to do it now.

    The Windows driver .inf disables ASPM on hpsa devices. Do the same because the
    selection of a non default ASPM policy can cause the device to hang.

    Doesn't completely do the teardown.  The true fix is to do a proper
    teardown instead of hand rolling it

    ALSA: hda - Fix the connection selection of ADCs on Cirrus codecs
    
    commit 05ee7964a470d29889ac48cc8274c1b5a1904a11 upstream.
    
    spec->cur_adc isn't set until cs_capture_pcm_prepare() is called although
    the driver tries to select the connection at init time and at auto-mic
    switch.  This results in the access to the widget NID 0, which is
    obviously invalid, also a wrong capture source.
    
    This patch fixes the issue by issuing the connect-select verb conditionally
    at appropriate places.

    genirq: Fix irqfixup, irqpoll regression
    
    commit c75d720fca8a91ce99196d33adea383621027bf2 upstream.
    
    commit d05c65fff0 ("genirq: spurious: Run only one poller at a time")
    introduced a regression, leaving the boot options 'irqfixup' and
    'irqpoll' non-functional. The patch placed tests in each function, to
    exit if the function is already running. The test in 'misrouted_irq'
    exited when it should have proceeded, effectively disabling
    'misrouted_irq' and 'poll_spurious_irqs'.
    
    The check for an already running poller needs to be "!= 1" not "== 1"
    as "1" is the value when the first poller starts running.
