perf auxtrace: Fix queue resize

2018-09-09T08:32:41+00:00

commit 99cbbe56eb8bede625f410ab62ba34673ffa7d21 upstream.

When the number of queues grows beyond 32, the array of queues is
resized but not all members were being copied. Fix by also copying
'tid', 'cpu' and 'set'.

perf kvm: Fix subcommands on s390

2018-09-05T07:29:44+00:00

commit 8a95c8994509c55abf1e38c0cc037b1205725e21 upstream.

With commit eca0fa28cd0d ("perf record: Provide detailed information on
s390 CPU") s390 platform provides detailed type/model/capacity
information in the CPU identifier string instead of just "IBM/S390".

This breaks 'perf kvm' support which uses hard coded string IBM/S390 to
compare with the CPU identifier string. Fix this by changing the
comparison.

bpf, sockmap: fix cork timeout for select due to epipe

2018-08-08T19:06:17+00:00

I ran into the same issue as a009f1f396d0 ("selftests/bpf:
test_sockmap, timing improvements") where I had a broken
pipe error on the socket due to remote end timing out on
select and then shutting down it's sockets while the other
side was still sending. We may need to do a bigger rework
in general on the test_sockmap.c, but for now increase it
to a more suitable timeout.

 "A set of fixes for perf:

  Kernel side:

   - Fix the hardcoded index of extra PCI devices on Broadwell which
     caused a resource conflict and triggered warnings on CPU hotplug.

  Tooling:

   - Update the tools copy of several files, including perf_event.h,
     powerpc's asm/unistd.h (new io_pgetevents syscall), bpf.h and x86's
     memcpy_64.s (used in 'perf bench mem'), silencing the respective
     warnings during the perf tools build.

   - Fix the build on the alpine:edge distro"

====================
pull-request: bpf 2018-08-05

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix bpftool percpu_array dump by using correct roundup to next
   multiple of 8 for the value size, from Yonghong.

2) Fix in AF_XDP's __xsk_rcv_zc() to not returning frames back to
   allocator since driver will recycle frame anyway in case of an
   error, from Jakub.

3) Fix up BPF test_lwt_seg6local test cases to final iproute2
   syntax, from Mathieu.

selftests/bpf: update test_lwt_seg6local.sh according to iproute2

2018-08-03T08:19:33+00:00

The shell file for test_lwt_seg6local contains an early iproute2 syntax
for installing a seg6local End.BPF route. iproute2 support for this
feature has recently been upstreamed, but with an additional keyword
required. This patch updates test_lwt_seg6local.sh to the definitive
iproute2 syntax

Pull power management fixes from Rafael Wysocki:
 "These fix the scope of a recent intel_pstate driver optimization used
  incorrectly on some systems due to processor identification ambiguity
  and fix a few issues in the turbostat utility, including three recent
  regressions.

  Specifics:

   - Use ACPI FADT preferred PM Profile to distinguish Skylake desktop
     processors from some server ones with the same model number in
     order to limit the scope of the recent IO-wait boost optimization
     to servers, as intended (Srinivas Pandruvada).

   - Fix several issues in the turbostat utility:
      * Fix the -S option on 1-CPU systems (Len Brown).
      * Fix computations using incorrect processor core counts (Artem
        Bityutskiy).
      * Fix the x2apic debug message (Len Brown).
      * Fix logical node enumeration to allow for non-sequential
        physical nodes (Prarit Bhargava).
