Pull two 'perf bench' fixes from Arnaldo:

  * Make 'perf bench mem' (i.e. no args) mean 'run all tests' so that we can run
    all tests, not stopping at the numa ones.  (Arnaldo Carvalho de Melo)

  * Fix NULL pointer dereference after last test in in "perf bench all" (Patrick Palka)

perf bench: Fix NULL pointer dereference in "perf bench all"

2014-03-14T16:45:54+00:00

The for_each_bench() macro must check that the "benchmarks" field of a
collection is not NULL before dereferencing it because the "all"
collection in particular has a NULL "benchmarks" field (signifying that
it has no benchmarks to iterate over).

This fixes this NULL pointer dereference when running "perf bench all":

  [root@ssdandy ~]# perf bench all
  

  # Running mem/memset benchmark...
  # Copying 1MB Bytes ...

         2.453675 GB/Sec
        12.056327 GB/Sec (with prefault)

  Segmentation fault (core dumped)

perf bench numa: Make no args mean 'run all tests'

2014-03-14T13:04:10+00:00

If we call just:

  perf bench numa mem

it will present the same output as:

  perf bench numa mem -h

i.e. ask for instructions about what to run.

While that is kinda ok, using 'run all tests' as the default, i.e.
making 'no parms' be equivalent to:

  perf bench numa mem -a

Will allow:

  perf bench numa all

to actually do what is asked: i.e. run all the 'bench' tests, instead of
responding to that by asking what to do.

That, in turn, allows:

  perf bench all

to actually complete, for the same reasons.

And after that, the tests that come after that, and that at some point
hit a NULL deref, will run, allowing me to reproduce a recently reported
problem.

That when you have the needed numa libraries, which wasn't the case for
the reporter, making me a bit confused after trying to reproduce his
report.

So make no parms mean -a.

Pull networking fixes from David Miller:
 "I know this is a bit more than you want to see, and I've told the
  wireless folks under no uncertain terms that they must severely scale
  back the extent of the fixes they are submitting this late in the
  game.

  Anyways:

   1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
      is the correct implementation, like it should.  Instead it does
      something like a NAPI poll operation.  This leads to crashes.

      From Neil Horman and Arnd Bergmann.

   2) Segmentation of SKBs requires proper socket orphaning of the
      fragments, otherwise we might access stale state released by the
      release callbacks.

      This is a 5 patch fix, but the initial patches are giving
      variables and such significantly clearer names such that the
      actual fix itself at the end looks trivial.

      From Michael S.  Tsirkin.

   3) TCP control block release can deadlock if invoked from a timer on
      an already "owned" socket.  Fix from Eric Dumazet.

   4) In the bridge multicast code, we must validate that the
      destination address of general queries is the link local all-nodes
      multicast address.  From Linus Lüssing.

   5) The x86 BPF JIT support for negative offsets puts the parameter
      for the helper function call in the wrong register.  Fix from
      Alexei Starovoitov.

   6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
      r8169 driver is incorrect.  Fix from Hayes Wang.

   7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
      if a packet is a GSO frame, but that's not the correct test.  It
      should use skb_is_gso(skb) instead.  Fix from Wei Liu.

   8) Negative msg->msg_namelen values should generate an error, from
      Matthew Leach.

   9) at86rf230 can deadlock because it takes the same lock from it's
      ISR and it's hard_start_xmit method, without disabling interrupts
      in the latter.  Fix from Alexander Aring.

  10) The FEC driver's restart doesn't perform operations in the correct
      order, so promiscuous settings can get lost.  Fix from Stefan
      Wahren.

  11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.

  12) Reference count and memory leak fixes in TIPC from Ying Xue and
      Erik Hugne.

  13) Forced eviction in inet_frag_evictor() must strictly make sure all
      frags are deleted, otherwise module unload (f.e.  6lowpan) can
      crash.  Fix from Florian Westphal.

  14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
      uses as a hash function), which breaks on PowerPC.  From Anton
      Blanchard.

      The main gist of the issue is that csum_partial() is defined only
      as a value that, once folded (f.e.  via csum_fold()) produces a
      correct 16-bit checksum.  It is legitimate, therefore, for
      csum_partial() to produce two different 32-bit values over the
      same data if their respective alignments are different.

  15) Fix endiannes bug in MAC address handling of ibmveth driver, also
      from Anton Blanchard.

  16) Error checks for ipv6 exthdrs offload registration are reversed,
      from Anton Nayshtut.

  17) Externally triggered ipv6 addrconf routes should count against the
      garbage collection threshold.  Fix from Sabrina Dubroca.

  18) The PCI shutdown handler added to the bnx2 driver can wedge the
      chip if it was not brought up earlier already, which in particular
      causes the firmware to shut down the PHY.  Fix from Michael Chan.

  19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
      currently coded it can and does trigger in legitimate situations.
      From Eric Dumazet.

  20) BNA driver fails to build on ARM because of a too large udelay()
      call, fix from Ben Hutchings.

  21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
      from Eric Dumazet.

  22) The vlan passthrough ops added in the previous release causes a
      regression in source MAC address setting of outgoing headers in
      some circumstances.  Fix from Peter Boström"

perf machine: Use map as success in ip__resolve_ams

2014-03-10T14:19:36+00:00

When trying to map a bunch of instruction addresses to their respective
threads, I kept getting a lot of bogus entries [I forget the exact
reason as I patched my code months ago].

Looking through ip__resolve_ams, I noticed the check for

  if (al.sym)

and realized, most times I have an al.map definition but sometimes an
al.sym is undefined.  In the cases where al.sym is undefined, the loop
keeps going even though a valid al.map exists.

Modify this check to use the more reliable al.map.  This fixed my bogus
entries.
