      Kill indirect include of file.h from eventfd.h, use fdget() in cgroup.c · 4e10f3c9
      Al Viro authored
      
      
      kernel/cgroup.c is the only place in the tree that relies on eventfd.h
      pulling file.h; move that include there.  Switch from eventfd_fget()/fput()
      to fdget()/fdput(), while we are at it - eventfd_ctx_fileget() will fail
      on non-eventfd descriptors just fine, no need to do that check twice...

      exportfs: don't assume that ->iterate() won't feed us too long entries · dfc59e2c
      Al Viro authored
      
      
      On some filesystems it's impossible even with fs corruption, but we'd
      better not rely on that, what with memcpy() into on-stack array we
      are doing there.

      afs: get rid of redundant ->d_name.len checks · 5d8943b0
      Al Viro authored
      
      
      No dentry can get to directory modification methods without
      having passed either ->lookup() or ->atomic_open(); if name is
      rejected by those two (or by ->d_hash()) with an error, it won't
      be seen by anything else.

      lockref: add ability to mark lockrefs "dead" · e7d33bb5
      Linus Torvalds authored
      
      
      The only actual current lockref user (dcache) uses zero reference counts
      even for perfectly live dentries, because it's a cache: there may not be
      any users, but that doesn't mean that we want to throw away the dentry.
      
      At the same time, the dentry cache does have a notion of a truly "dead"
      dentry that we must not even increment the reference count of, because
      we have pruned it and it is not valid.
      
      Currently that distinction is not visible in the lockref itself, and the
      dentry cache validation uses "lockref_get_or_lock()" to either get a new
      reference to a dentry that already had existing references (and thus
      cannot be dead), or get the dentry lock so that we can then verify the
      dentry and increment the reference count under the lock if that
      verification was successful.
      
      That's all somewhat complicated.
      
      This adds the concept of being "dead" to the lockref itself, by simply
      using a count that is negative.  This allows a usage scenario where we
      can increment the refcount of a dentry without having to validate it,
      and pushing the special "we killed it" case into the lockref code.
      
      The dentry code itself doesn't actually use this yet, and it's probably
      too late in the merge window to do that code (the dentry_kill() code
      with its "should I decrement the count" logic really is pretty complex
      code), but let's introduce the concept at the lockref level now.

      The code got rewritten, but the comments got copied as-is from older
      versions, and as a result the argument name in the comment didn't
      actually match the code any more.

        The major theme is user namespace mount restrictions.  nsown_capable

        considered.  A very hard to hit pid namespace exiting bug was finally
        tracked and fixed.  A couple of cleanups to the basic namespace
        infrastructure.
      
        Finally there is an enhancement that makes per user namespace
        capabilities usable as capabilities, and an enhancement that allows
        the per userns root to nice other processes in the user namespace"

      Pull ARM SoC platform changes from Olof Johansson:
       "This branch contains mostly additions and changes to platform
        enablement and SoC-level drivers.  Since there's sometimes a
        dependency on device-tree changes, there's also a fair amount of
        those in this branch.
      
        Pieces worth mentioning are:
      
         - Mbus driver for Marvell platforms, allowing kernel configuration
           and resource allocation of on-chip peripherals.
         - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
         - Preparation of MSI support for Marvell platforms.
         - Addition of new PCI-e host controller driver for Tegra platforms
         - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
           platforms in the device tree sources and header files.
         - Various suspend/PM updates for Tegra, including LP1 support.
         - Versatile Express support for MCPM, part of big little support.
         - Allwinner platform support for A20 and A31 SoCs (dual and quad
           Cortex-A7)
         - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
      
        The code that touches other architectures are patches moving MSI
        arch-specific functions over to weak symbols and removal of
        ARCH_SUPPORTS_MSI, acked by PCI maintainers"

      tcp: properly increase rcv_ssthresh for ofo packets · 4e4f1fc2
      Eric Dumazet authored
      
      
      TCP receive window handling is multi staged.
      
      A socket has a memory budget, static or dynamic, in sk_rcvbuf.
      
      Because we do not really know how this memory budget translates to
      a TCP window (payload), TCP announces a small initial window
      (about 20 MSS).
      
      When a packet is received, we increase TCP rcv_win depending
      on the payload/truesize ratio of this packet. Good citizen
      packets give a hint that it's reasonable to have rcv_win = sk_rcvbuf/2
      
      This heuristic takes place in tcp_grow_window()
      
      Problem is : We currently call tcp_grow_window() only for in-order
      packets.
      
      This means that reorders or packet losses stop proper grow of
      rcv_win, and senders are unable to benefit from fast recovery,
      or proper reordering level detection.
      
      Really, a packet being stored in OFO queue is not a bad citizen.
      It should be part of the game as in-order packets.
      
      In our traces, we very often see sender is limited by linux small
      receive windows, even if linux hosts use autotuning (DRS) and should
      allow rcv_win to grow to ~3MB.

      tcp: fix no cwnd growth after timeout · 16edfe7e
      Yuchung Cheng authored
      In commit 0f7cc9a3
      
       "tcp: increase throughput when reordering is high",
      it only allows cwnd to increase in Open state. This mistakenly disables
      slow start after timeout (CA_Loss). Moreover cwnd won't grow if the
      state moves from Disorder to Open later in tcp_fastretrans_alert().
      
      Therefore the correct logic should be to allow cwnd to grow as long
      as the data is received in order in Open, Loss, or even Disorder state.

       "Here's the powerpc batch for this merge window.  Some of the
        highlights are:
      
         - A bunch of endian fixes ! We don't have full LE support yet in that
           release but this contains a lot of fixes all over arch/powerpc to
           use the proper accessors, call the firmware with the right endian
           mode, etc...
      
         - A few updates to our "powernv" platform (non-virtualized, the one
           to run KVM on), among other, support for bridging the P8 LPC bus
           for UARTs, support and some EEH fixes.
      
         - Some mpc51xx clock API cleanups in preparation for a clock API
           overhaul
      
         - A pile of cleanups of our old math emulation code, including better
           support for using it to emulate optional FP instructions on
           embedded chips that otherwise have a HW FPU.
      
         - Some infrastructure in selftest, for powerpc now, but could be
           generalized, initially used by some tests for our perf instruction
           counting code.
      
         - A pile of fixes for hotplug on pseries (that was seriously
           bitrotting)
      
         - The usual slew of freescale embedded updates, new boards, 64-bit
           hiberation support, e6500 core PMU support, etc..."

      These are based on the current shipping versions of the config files
      from Tilera, as synced up to the tip, so are a better starting point
      for folks who want a default configuration.

      tile: rework <asm/cmpxchg.h> · 6dc9658f
      Chris Metcalf authored
      
      
      The macrology in cmpxchg.h was designed to allow arbitrary pointer
      and integer values to be passed through the routines.  To support
      cmpxchg() on 64-bit values on the 32-bit tilepro architecture, we
      used the idiom "(typeof(val))(typeof(val-val))".  This way, in the
      "size 8" branch of the switch, when the underlying cmpxchg routine
      returns a 64-bit quantity, we cast it first to a typeof(val-val)
      quantity (i.e. size_t if "val" is a pointer) with no warnings about
      casting between pointers and integers of different sizes, then cast
      onwards to typeof(val), again with no warnings.  If val is not a
      pointer type, the additional cast is a no-op.  We can't replace the
      typeof(val-val) cast with (for example) unsigned long, since then if
      "val" is really a 64-bit type, we cast away the high bits.
      
      HOWEVER, this fails with current gcc (through 4.7 at least) if "val"
      is a pointer to an incomplete type.  Unfortunately gcc isn't smart
      enough to realize that "val - val" will always be a size_t type
      even if it's an incomplete type pointer.
      
      Accordingly, I've reworked the way we handle the casting.  We have
      given up the ability to use cmpxchg() on 64-bit values on tilepro,
      which is OK in the kernel since we should use cmpxchg64() explicitly
      on such values anyway.  As a result, I can just use simple "unsigned
      long" casts internally.
      
      As I reworked it, I realized it would be cleaner to move the
      architecture-specific conditionals for cmpxchg and xchg out of the
      atomic.h headers and into cmpxchg, and then use the cmpxchg() and
      xchg() primitives directly in atomic.h and elsewhere.  This allowed
      the cmpxchg.h header to stand on its own without relying on the
      implicit include of it that is performed by <asm/atomic.h>.
      It also allowed collapsing the atomic_xchg/atomic_cmpxchg routines
      from atomic_{32,64}.h into atomic.h.
      
      I improved the tests that guard the allowed size of the arguments
      to the routines to use a __compiletime_error() test.  (By avoiding
      the use of BUILD_BUG, I could include cmpxchg.h into bitops.h as
      well and use the macros there, which is otherwise impossible due
      to include order dependency issues.)
      
      The tilepro _atomic_xxx internal methods were previously set up to
      take atomic_t and atomic64_t arguments, which isn't as convenient
      with the new model, so I modified them to take int or u64 arguments,
      which is consistent with how they used the arguments internally
      anyway, so provided some nice simplification there too.
