    ext4: don't set i_flags in EXT4_IOC_SETFLAGS

    commit b22b1f178f6799278d3178d894f37facb2085765 upstream.

    Commit 7990696 uses the ext4_{set,clear}_inode_flags() functions to
    change the i_flags automatically but fails to remove the error setting
    of i_flags.  So we still have the problem of trashing state flags.
    Fix this by removing the assignment.

    wl1251: fix oops on early interrupt

    commit f380f2c4a12e913356bd49f8790ec1063c4fe9f8 upstream.

    This driver disables interrupt just after requesting it and enables it
    later, after interface is up. However currently there is a time window
    between request_irq() and disable_irq() where if interrupt arrives, the
    driver oopses because it's not yet ready to process it. This can be
    reproduced by inserting the module, associating and removing the module
    multiple times.

    Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

    ext4: remove mb_groups before tearing down the buddy_cache

    commit 95599968d19db175829fb580baa6b68939b320fb upstream.

    We can't have references held on pages in the s_buddy_cache while we are
    trying to truncate its pages and put the inode.  All the pages must be
    gone before we reach clear_inode.  This can only be gauranteed if we
    can prevent new users from grabbing references to s_buddy_cache's pages.

    The original bug can be reproduced and the bug fix can be verified by:

    while true; do mount -t ext4 /dev/ram0 /export/hda3/ram0; \
    	umount /export/hda3/ram0; done &

    ext4: don't trash state flags in EXT4_IOC_SETFLAGS

    commit 79906964a187c405db72a3abc60eb9b50d804fbc upstream.

    In commit 353eb83c we removed i_state_flags with 64-bit longs, But
    when handling the EXT4_IOC_SETFLAGS ioctl, we replace i_flags
    directly, which trashes the state flags which are stored in the high
    32-bits of i_flags on 64-bit platforms.  So use the the
    ext4_{set,clear}_inode_flags() functions which use atomic bit
    manipulation functions instead.

    ext4: add missing save_error_info() to ext4_error()

    commit f3fc0210c0fc91900766c995f089c39170e68305 upstream.

    The ext4_error() function is missing a call to save_error_info().
    Since this is the function which marks the file system as containing
    an error, this oversight (which was introduced in 2.6.36) is quite
    significant, and should be backported to older stable kernels with
    high urgency.

    xfrm: take net hdr len into account for esp payload size calculation

    [ Upstream commit 91657eafb64b4cb53ec3a2fbc4afc3497f735788 ]

    Corrects the function that determines the esp payload size. The calculations
    done in esp{4,6}_get_mtu() lead to overlength frames in transport mode for
    certain mtu values and suboptimal frames for others.

    According to what is done, mainly in esp{,6}_output() and tcp_mtu_to_mss(),
    net_header_len must be taken into account before doing the alignment
    calculation.

    skb: avoid unnecessary reallocations in __skb_cow

    [ Upstream commit 617c8c11236716dcbda877e764b7bf37c6fd8063 ]

    At the beginning of __skb_cow, headroom gets set to a minimum of
    NET_SKB_PAD. This causes unnecessary reallocations if the buffer was not
    cloned and the headroom is just below NET_SKB_PAD, but still more than the
    amount requested by the caller.
    This was showing up frequently in my tests on VLAN tx, where
    vlan_insert_tag calls skb_cow_head(skb, VLAN_HLEN).

    Locally generated packets should have enough headroom, and for forward
    paths, we already have NET_SKB_PAD bytes of headroom, so we don't need to
    add any extra space here.

    It causes regressions for S390 devices, because it does an

    l2tp: fix oops in L2TP IP sockets for connect() AF_UNSPEC case

    [ Upstream commit c51ce49735c183ef2592db70f918ee698716276b ]

    An application may call connect() to disconnect a socket using an
    address with family AF_UNSPEC. The L2TP IP sockets were not handling
    this case when the socket is not bound and an attempt to connect()
    using AF_UNSPEC in such cases would result in an oops. This patch
    addresses the problem by protecting the sk_prot->disconnect() call
    against trying to unhash the socket before it is bound.

    The patch also adds more checks that the sockaddr supplied to bind()
    and connect() calls is valid.

    ipv6: fix incorrect ipsec fragment

    [ Upstream commit 0c1833797a5a6ec23ea9261d979aa18078720b74 ]

    Since commit ad0081e43a
    "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
    the fragment of packets is incorrect.
    because tunnel mode needs IPsec headers and trailer for all fragments,
    while on transport mode it is sufficient to add the headers to the
    first fragment and the trailer to the last.

    so modify mtu and maxfraglen base on ipsec mode and if fragment is first
    or last.

    with my test,it work well(every fragment's size is the mtu)
    and does not trigger slow fragment path.

    Changes from v1:
    	though optimization, mtu_prev and maxfraglen_prev can be delete.
    	replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
    	add fuction ip6_append_data_mtu to make codes clearer.

    Function free_fib_info resets nexthop_nh->nh_dev to NULL before releasing
    fi. Other cpu might be accessing fi. Fixing it by delaying the releasing.

    With the patch, we ran MTBF testing on Android mobile for 12 hours
    and didn't trigger the issue.

    Thank Eric for very detailed review/checking the issue.

    ipv4: Do not use dead fib_info entries.

    [ Upstream commit dccd9ecc374462e5d6a5b8f8110415a86c2213d8 ]

    Due to RCU lookups and RCU based release, fib_info objects can
    be found during lookup which have fi->fib_dead set.

    We must ignore these entries, otherwise we risk dereferencing
    the parts of the entry which are being torn down.

    Bluetooth: btusb: typo in Broadcom SoftSailing id

    commit 2e8b506310f6433d5558387fd568d4bfb1d6a799 upstream.

    I was trying to backport the following commit to RHEL-6

        From 0cea73465cd22373c5cd43a3edd25fbd4bb532ef Mon Sep 17 00:00:00 2001
        From: Oliver Neukum <oliver@neukum.org>
        Date: Wed, 21 Sep 2011 11:37:15 +0200
        Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing

    and noticed it wasn't working on an HP Elitebook.  Looking into the patch I
    noticed a very subtle typo in the ids.  The patch has '0x05ac' instead of
    '0x0a5c'.  A snippet of the lsusb -v output also shows this:

    Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp.
    Device Descriptor:
      bLength                18
      bDescriptorType         1
      bcdUSB               2.00
      bDeviceClass          255 Vendor Specific Class
      bDeviceSubClass         1
      bDeviceProtocol         1
      bMaxPacketSize0        64
      idVendor           0x0a5c Broadcom Corp.
      idProduct          0x21e1
      bcdDevice            1.12
      iManufacturer           1 Broadcom Corp
      iProduct                2 BCM20702A0
      iSerial                 3 60D819F0338C
      bNumConfigurations      1

    Looking at other Broadcom ids, the fix matches them whereas the original patch
    matches Apple's ids.

    Tested on an HP Elitebook 8760w.  The btusb binds and the userspace stuff loads
    correctly.

    solos-pci: Fix DMA support

    commit b4bd8ad9bb311e8536f726f7a633620ccd358cde upstream.

    DMA support has finally made its way to the top of the TODO list, having
    realised that a Geode using MMIO can't keep up with two ADSL2+ lines
    each running at 21Mb/s.

    This patch fixes a couple of bugs in the DMA support in the driver, so
    once the corresponding FPGA update is complete and tested everything
    should work properly.

    We weren't storing the currently-transmitting skb, so we were never
    unmapping it and never freeing/popping it when the TX was done.
    And the addition of pci_set_master() is fairly self-explanatory.

    also work.  Even on narrow systems, these paths require using the wide
    instructions becuase the tlb insertion format is wide.  Fix this by

    commit ed5fb2471b7060767957fb964eb1aaec71533ab1 upstream.

    In certain configurations, the resulting kernel becomes too large to boot
    because the linker places the long branch stubs for the merged .text section
    at the very start of the image.  As a result, the initial transfer of control
    jumps to an unexpected location.  Fix this by placing the head text in a

    cifs: fix oops while traversing open file list (try #4)

    commit 2c0c2a08bed7a3b791f88d09d16ace56acb3dd98 upstream.

    While traversing the linked list of open file handles, if the identfied
    file handle is invalid, a reopen is attempted and if it fails, we
    resume traversing where we stopped and cifs can oops while accessing
    invalid next element, for list might have changed.

    So mark the invalid file handle and attempt reopen if no
    valid file handle is found in rest of the list.
    If reopen fails, move the invalid file handle to the end of the list
    and start traversing the list again from the begining.
    Repeat this four times before giving up and returning an error if
    file reopen keeps failing.

    iwlwifi: update BT traffic load states correctly

    commit 882dde8eb0d49ce0f853f8f4084dde56a21fe55f upstream.

    When BT traffic load changes from its
    previous state, a new LQ command needs to be
    sent down to the firmware. This needs to
    be done only once per change. The state
    variable that keeps track of this change is
    last_bt_traffic_load. However, it was not
    being updated when the change had been
    handled. Not updating this variable was
    causing a flood of advanced BT config
    commands to be sent to the firmware. Fix
    this.

    When holding the mmap_sem for reading, pmd_offset_map_lock should only
    run on a pmd_t that has been read atomically from the pmdp pointer,
    otherwise we may read only half of it leading to this crash.

    This should be a longstanding bug affecting x86 32bit PAE without THP.
    Only archs with 64bit large pmd_t and 32bit unsigned long should be
    affected.

    With THP enabled the barrier() in pmd_none_or_trans_huge_or_clear_bad()
    would partly hide the bug when the pmd transition from none to stable,
    by forcing a re-read of the *pmd in pmd_offset_map_lock, but when THP is
    enabled a new set of problem arises by the fact could then transition
    freely in any of the none, pmd_trans_huge or pmd_trans_stable states.
    So making the barrier in pmd_none_or_trans_huge_or_clear_bad()
    unconditional isn't good idea and it would be a flakey solution.

    This should be fully fixed by introducing a pmd_read_atomic that reads
    the pmd in order with THP disabled, or by reading the pmd atomically
    with cmpxchg8b with THP enabled.

    Luckily this new race condition only triggers in the places that must
    already be covered by pmd_none_or_trans_huge_or_clear_bad() so the fix
    is localized there but this bug is not related to THP.

    NOTE: this can trigger on x86 32bit systems with PAE enabled with more
    than 4G of ram, otherwise the high part of the pmd will never risk to be
    truncated because it would be zero at all times, in turn so hiding the
    SMP race.

    This bug was discovered and fully debugged by Ulrich, quote:

    [..]

    Please note that the PMD is not read atomically. These are two "mov"
    instructions where the high order bits of the PMD entry are fetched
    first. Hence, the above machine code is prone to the following race.

    -  The PMD entry {high|low} is 0x0000000000000000.
       The "mov" at 0xc0507a84 loads 0x00000000 into edx.

    -  A page fault (on another CPU) sneaks in between the two "mov"
       instructions and instantiates the PMD.

    -  The PMD entry {high|low} is now 0x00000003fda38067.
       The "mov" at 0xc0507a8e loads 0xfda38067 into eax.

    mm: consider all swapped back pages in used-once logic

    commit e48982734ea0500d1eba4f9d96195acc5406cad6 upstream.

    Commit 645747462435 ("vmscan: detect mapped file pages used only once")
    made mapped pages have another round in inactive list because they might
    be just short lived and so we could consider them again next time.  This
    heuristic helps to reduce pressure on the active list with a streaming
    IO worklods.

    This patch fixes a regression introduced by this commit for heavy shmem
    based workloads because unlike Anon pages, which are excluded from this
    heuristic because they are usually long lived, shmem pages are handled
    as a regular page cache.

    This doesn't work quite well, unfortunately, if the workload is mostly
    backed by shmem (in memory database sitting on 80% of memory) with a
    streaming IO in the background (backup - up to 20% of memory).  Anon
    inactive list is full of (dirty) shmem pages when watermarks are hit.
    Shmem pages are kept in the inactive list (they are referenced) in the
    first round and it is hard to reclaim anything else so we reach lower
    scanning priorities very quickly which leads to an excessive swap out.

    Let's fix this by excluding all swap backed pages (they tend to be long
    lived wrt.  the regular page cache anyway) from used-once heuristic and
    rather activate them if they are referenced.

    The customer's workload is shmem backed database (80% of RAM) and they
    are measuring transactions/s with an IO in the background (20%).
    Transactions touch more or less random rows in the table.  The
    transaction rate fell by a factor of 3 (in the worst case) because of
    commit 64574746.  This patch restores the previous numbers.

    SCSI: Fix dm-multipath starvation when scsi host is busy

    commit b7e94a1686c5daef4f649f7f4f839cc294f07710 upstream.

    block congestion control doesn't have any concept of fairness across
    multiple queues.  This means that if SCSI reports the host as busy in
    the queue congestion control it can result in an unfair starvation
    situation in dm-mp if there are multiple multipath devices on the same
    host.  For example:
    http://www.redhat.com/archives/dm-devel/2012-May/msg00123.html

    The fix for this is to report only the sdev busy state (and ignore the
    host busy state) in the block congestion control call back.
    The host is still congested, but the SCSI subsystem will sort out the
    congestion in a fair way because it knows the relation between the
    queues and the host.

    SCSI: fix scsi_wait_scan

        PM/Hibernate: Wait for SCSI devices scan to complete during resume

    Broke the scsi_wait_scan module in 2.6.30.  Apparently debian still uses it so
    fix it and backport to stable before removing it in 3.6.

    The breakage is caused because the function template in
    include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in.
    That means that in the modular case (which is every distro), the
    scsi_wait_scan module does a simple async_synchronize_full() instead of
    waiting for scans.
