    Resource: fix wrong resource window calculation

    commit 47ea91b4052d9e94b9dca5d7a3d947fbebd07ba9 upstream.

    __find_resource() incorrectly returns a resource window which overlaps
    an existing allocated window.  This happens when the parent's
    resource-window spans 0x00000000 to 0xffffffff and is entirely allocated
    to all its children resource-windows.

    __find_resource() looks for gaps in resource allocation among the
    children resource windows.  When it encounters the last child window it
    blindly tries the range next to one allocated to the last child.  Since
    the last child's window ends at 0xffffffff the calculation overflows,
    leading the algorithm to believe that any window in the range 0x0000000
    to 0xfffffff is available for allocation.  This leads to a conflicting
    window allocation.

    Michal Ludvig reported this issue seen on his platform.  The following
    patch fixes the problem and has been verified by Michal.  I believe this
    bug has been there for ages.  It got exposed by git commit 2bbc6942273b
    ("PCI : ability to relocate assigned pci-resources")

    PCI : Calculate right add_size

    commit a4ac9fea016fc5c09227eb479bd35e34978323a4 upstream.

    During debug of one SRIOV enabled hotplug device, we found found that
    add_size is not passed properly.

    The device has devices under two level bridges:

     +-[0000:80]-+-00.0-[81-8f]--
     |           +-01.0-[90-9f]--
     |           +-02.0-[a0-af]----00.0-[a1-a3]--+-02.0-[a2]--+-00.0  Oracle Corporation Device
     |           |                               \-03.0-[a3]--+-00.0  Oracle Corporation Device

    Which means later the parent bridge will not try to add a big enough range:

    [  557.455077] pci 0000:a0:00.0: BAR 14: assigned [mem 0xf9000000-0xf93fffff]

    [  557.519578] pci 0000:a1:02.0: failed to add optional resources res=[mem 0xf9000000-0xf91fffff]

    It turns out we did not calculate size1 properly.

    static resource_size_t calculate_memsize(resource_size_t size,
                    resource_size_t min_size,
                    resource_size_t size1,
                    resource_size_t old_size,
                    resource_size_t align)
    {
            if (size < min_size)
                    size = min_size;
            if (old_size == 1 )
                    old_size = 0;
            if (size < old_size)
                    size = old_size;
            size = ALIGN(size + size1, align);
            return size;
    }

    We should not pass add_size with min_size in calculate_memsize since
    that will make add_size not contribute final add_size.

    So just pass add_size with size1 to calculate_memsize().

    With this change, we should have chance to remove extra addon in
    pci_reassign_resource.

    PCI : ability to relocate assigned pci-resources

    commit 2bbc6942273b5b3097bd265d82227bdd84b351b2 upstream.

    Currently pci-bridges are allocated enough resources to satisfy their immediate
    requirements.  Any additional resource-requests fail if additional free space,
    contiguous to the one already allocated, is not available. This behavior is not
    reasonable since sufficient contiguous resources, that can satisfy the request,
    are available at a different location.

    This patch provides the ability to expand and relocate a allocated resource.

    NFS: Wait for session recovery to finish before returning

    commit 399f11c3d872bd748e1575574de265a6304c7c43 upstream.

    Currently, we will schedule session recovery and then return to the
    caller of nfs4_handle_exception.  This works for most cases, but causes
    a hang on the following test case:

    	Client				Server
    	------				------
    	Open file over NFS v4.1
    	Write to file
    					Expire client
    	Try to lock file

    The server will return NFS4ERR_BADSESSION, prompting the client to
    schedule recovery.  However, the client will continue placing lock
    attempts and the open recovery never seems to be scheduled.  The
    simplest solution is to wait for session recovery to run before retrying
    the lock.

    drm/i915: fix overlay on i830M

    commit a9193983f4f292a82a00c72971c17ec0ee8c6c15 upstream.

    The overlay on the i830M has a peculiar failure mode: It works the
    first time around after boot-up, but consistenly hangs the second time
    it's used.

    Chris Wilson has dug out a nice errata:

    "1.5.12 Clock Gating Disable for Display Register
    Address Offset:	06200h–06203h

    "Bit 3
    Ovrunit Clock Gating Disable.
    0 = Clock gating controlled by unit enabling logic
    1 = Disable clock gating function
    DevALM Errata ALM049: Overlay Clock Gating Must be Disabled:  Overlay
    & L2 Cache clock gating must be disabled in order to prevent device
    hangs when turning off overlay.SW must turn off Ovrunit clock gating
    (6200h) and L2 Cache clock gating (C8h)."

    Now I've nowhere found that 0xc8 register and hence couldn't apply the
    l2 cache workaround. But I've remembered that part of the magic that
    the OVERLAY_ON/OFF commands are supposed to do is to rearrange cache
    allocations so that the overlay scaler has some scratch space.

    And while pondering how that could explain the hang the 2nd time we
    enable the overlay, I've remembered that the old ums overlay code did
    _not_ issue the OVERLAY_OFF cmd.

    And indeed, disabling the OFF cmd results in the overlay working
    flawlessly, so I guess we can workaround the lack of the above
    workaround by simply never disabling the overlay engine once it's
    enabled.

    Note that we have the first part of the above w/a already implemented
    in i830_init_clock_gating - leave that as-is to avoid surprises.

    v2: Add a comment in the code.

    eCryptfs: Copy up POSIX ACL and read-only flags from lower mount

    commit 069ddcda37b2cf5bb4b6031a944c0e9359213262 upstream.

    When the eCryptfs mount options do not include '-o acl', but the lower
    filesystem's mount options do include 'acl', the MS_POSIXACL flag is not
    flipped on in the eCryptfs super block flags. This flag is what the VFS
    checks in do_last() when deciding if the current umask should be applied
    to a newly created inode's mode or not. When a default POSIX ACL mask is
    set on a directory, the current umask is incorrectly applied to new
    inodes created in the directory. This patch ignores the MS_POSIXACL flag
    passed into ecryptfs_mount() and sets the flag on the eCryptfs super
    block depending on the flag's presence on the lower super block.

    Additionally, it is incorrect to allow a writeable eCryptfs mount on top
    of a read-only lower mount. This missing check did not allow writes to
    the read-only lower mount because permissions checks are still performed
    on the lower filesystem's objects but it is best to simply not allow a
    rw mount on top of ro mount. However, a ro eCryptfs mount on top of a rw
    mount is valid and still allowed.

    netfilter: Validate the sequence number of dataless ACK packets as well

    commit 4a70bbfaef0361d27272629d1a250a937edcafe4 upstream.

    We spare nothing by not validating the sequence number of dataless
    ACK packets and enabling it makes harder off-path attacks.

    kbuild: Fix gcc -x syntax

    commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream.

    The correct syntax for gcc -x is "gcc -x assembler", not
    "gcc -xassembler". Even though the latter happens to work, the former
    is what is documented in the manual page and thus what gcc wrappers
    such as icecream do expect.

    This isn't a cosmetic change. The missing space prevents icecream from
    recognizing compilation tasks it can't handle, leading to silent kernel
    miscompilations.

    Besides me, credits go to Michael Matz and Dirk Mueller for
    investigating the miscompilation issue and tracking it down to this
    incorrect -x parameter syntax.

    r8169: use unlimited DMA burst for TX

    commit aee77e4accbeb2c86b1d294cd84fec4a12dde3bd upstream.

    The r8169 driver currently limits the DMA burst for TX to 1024 bytes. I have
    a box where this prevents the interface from using the gigabit line to its full
    potential. This patch solves the problem by setting TX_DMA_BURST to unlimited.

    The box has an ASRock B75M motherboard with on-board RTL8168evl/8111evl
    (XID 0c900880). TSO is enabled.

    I used netperf (TCP_STREAM test) to measure the dependency of TX throughput
    on MTU. I did it for three different values of TX_DMA_BURST ('5'=512, '6'=1024,
    '7'=unlimited). This chart shows the results:
    http://michich.fedorapeople.org/r8169/r8169-effects-of-TX_DMA_BURST.png

    Interesting points:
     - With the current DMA burst limit (1024):
       - at the default MTU=1500 I get only 842 Mbit/s.
       - when going from small MTU, the performance rises monotonically with
         increasing MTU only up to a peak at MTU=1076 (908 MBit/s). Then there's
         a sudden drop to 762 MBit/s from which the throughput rises monotonically
         again with further MTU increases.
     - With a smaller DMA burst limit (512):
       - there's a similar peak at MTU=1076 and another one at MTU=564.
     - With unlimited DMA burst:
       - at the default MTU=1500 I get nice 940 Mbit/s.
       - the throughput rises monotonically with increasing MTU with no strange
         peaks.

    Notice that the peaks occur at MTU sizes that are multiples of the DMA burst
    limit plus 52. Why 52? Because:
      20 (IP header) + 20 (TCP header) + 12 (TCP options) = 52

    The Realtek-provided r8168 driver (v8.032.00) uses unlimited TX DMA burst too,
    except for CFG_METHOD_1 where the TX DMA burst is set to 512 bytes.
    CFG_METHOD_1 appears to be the oldest MAC version of "RTL8168B/8111B",
    i.e. RTL_GIGA_MAC_VER_11 in r8169. Not sure if this MAC version really needs
    the smaller burst limit, or if any other versions have similar requirements.

    ipv4: avoid undefined behavior in do_ip_setsockopt()

    (1<<optname) is undefined behavior in C with a negative optname or

    not necessarily zero (e.g., on x86).

    This patch simplifies the code with a switch statement on optname.

    The sigaddset/sigdelset/sigismember functions that are implemented with
    bitfield insn cannot allow the sigset argument to be placed in a data
    register since the sigset is wider than 32 bits.  Remove the "d"
    constraint from the asm statements.

    The effect of the bug is that sending RT signals does not work, the signal

    When walking page tables we need to make sure that everything

    Otherwise we might calculate e.g. a pud pointer which is not

    UBIFS: fix mounting problems after power cuts

    commit a28ad42a4a0c6f302f488f26488b8b37c9b30024 upstream.

    This is a bugfix for a problem with the following symptoms:

    1. A power cut happens
    2. After reboot, we try to mount UBIFS
    3. Mount fails with "No space left on device" error message

    UBIFS complains like this:

    UBIFS error (pid 28225): grab_empty_leb: could not find an empty LEB

    The root cause of this problem is that when we mount, not all LEBs are
    categorized. Only those which were read are. However, the
    'ubifs_find_free_leb_for_idx()' function assumes that all LEBs were
    categorized and 'c->freeable_cnt' is valid, which is a false assumption.

    This patch fixes the problem by teaching 'ubifs_find_free_leb_for_idx()'
    to always fall back to LPT scanning if no freeable LEBs were found.

    This problem was reported by few people in the past, but Brent Taylor
    was able to reproduce it and send me a flash image which cannot be mounted,
    which made it easy to hunt the bug. Kudos to Brent.
