b2d35fa5fc selftests: add headers_install to lib.mk 
If the kernel headers aren't installed we can't build all the tests.
Add a new make target rule 'khdr' in the file lib.mk to generate the
kernel headers and that gets include for every test-dir Makefile that
includes lib.mk If the testdir in turn have its own sub-dirs the
top_srcdir needs to be set to the linux-rootdir to be able to generate
the kernel headers.

1632936480 perf tests: Fix record+probe_libc_inet_pton.sh without ping's debuginfo 
When we don't have the iputils-debuginfo package installed, i.e. when we
don't have the DWARF information needed to resolve ping's samples, we
end up failing this 'perf test' entry:

  # perf test ping
  62: probe libc's inet_pton & backtrace it with ping       : Ok
  # rpm -e iputils-debuginfo
  # perf test ping
  62: probe libc's inet_pton & backtrace it with ping       : FAILED!
  #

Fix it to accept "[unknown]" where the symbol + offset, when resolved,
is expected.

I think this will fail in the other arches as well, but since I can't
test now, I'm leaving s390x and ppc cases as-is.

904506562e tools/vm/slabinfo.c: fix sign-compare warning 
Currently we get the following compiler warning:

    slabinfo.c:854:22: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
       if (s->object_size < min_objsize)
                          ^

due to the mismatch of signed/unsigned comparison.  ->object_size and
->slab_size are never expected to be negative, so let's define them as
unsigned int.

[n-horiguchi@ah.jp.nec.com: convert everything - none of these can be negative]

b1a9e2535e perf trace: Use the raw_syscalls:sys_enter for the augmented syscalls 
Now we combine what comes from the "bpf-output" event, i.e. what is
added in the augmented_syscalls.c BPF program via the
__augmented_syscalls__ BPF map, i.e. the payload we get with
raw_syscalls:sys_enter tracepoints plus the pointer contents, right
after that payload, with the raw_syscall:sys_exit also added, without
augmentation, in the augmented_syscalls.c program.

The end result is that for the hooked syscalls, we get strace like
output with pointer expansion, something that wasn't possible before
with just raw_syscalls:sys_enter + raw_syscalls:sys_exit.

E.g.:

  #

Now to think how to hook on all syscalls, fallbacking to the non-augmented
raw_syscalls:sys_enter payload.

Probably the best way is to use a BPF_MAP_TYPE_PROG_ARRAY just like
samples/bpf/tracex5_kern.c does.

db2da3f85c perf trace: Setup augmented_args in the raw_syscalls:sys_enter handler 
Without using something to augment the raw_syscalls:sys_enter tracepoint
payload with the pointer contents, this will work just like before, i.e.
the augmented_args arg will be NULL and the augmented_args_size will be
0.

This just paves the way for the next cset where we will associate the
trace__sys_enter tracepoint handler with the augmented "bpf-output"
event named "__augmented_args__".

35386dfd13 spi: spidev_test: Improve decoded text part of hex dump 
- Print spaces as spaces,
  - Do not print characters > 126, as they will be shown as garbage
    in the modern UTF-8 era,
  - Use a normal period instead of its hexadecimal ASCII value,
  - Delimit the text part with pipe symbols on both sides (was left side
    only), without any spaces, to make it clear where the decoded text
    starts and ends,
  - Drop a useless comment.

7538d16397 perf augmented_syscalls: Avoid optimization to pass older BPF validators 
See https://www.spinics.net/lists/netdev/msg480099.html for the whole
discussio, but to make the augmented_syscalls.c BPF program to get built
and loaded successfully in a greater range of kernels, add an extra
check.

Related patch:

  a60dd35d2e ("bpf: change bpf_perf_event_output arg5 type to ARG_CONST_SIZE_OR_ZERO")

That is in the kernel since v4.15, I couldn't figure why this is hitting
me with 4.17.17, but adding the workaround discussed there makes this
work with this fedora kernel and with 4.18.recent.

21d7eb9a24 perf augmented_syscalls: Check probe_read_str() return separately 
Using a value returned from probe_read_str() to tell how many bytes to
copy using perf_event_output() has issues in some older kernels, like
4.17.17-100.fc27.x86_64, so separate the bounds checking done on how
many bytes to copy to a separate variable, so that the next patch has
only what is being done to make the test pass on older BPF validators.

For reference, see the discussion in this thread:

fbb0de7950 Add udmabuf misc device 
A driver to let userspace turn memfd regions into dma-bufs.

Use case:  Allows qemu create dmabufs for the vga framebuffer or
virtio-gpu ressources.  Then they can be passed around to display
those guest things on the host.  To spice client for classic full
framebuffer display, and hopefully some day to wayland server for
seamless guest window display.

fd3c040b24 Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next 
Daniel Borkmann says:

====================
pull-request: bpf-next 2018-09-01

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

The main changes are:

1) Add AF_XDP zero-copy support for i40e driver (!), from Björn and Magnus.

2) BPF verifier improvements by giving each register its own liveness
   chain which allows to simplify and getting rid of skip_callee() logic,
   from Edward.

3) Add bpf fs pretty print support for percpu arraymap, percpu hashmap
   and percpu lru hashmap. Also add generic percpu formatted print on
   bpftool so the same can be dumped there, from Yonghong.

4) Add bpf_{set,get}sockopt() helper support for TCP_SAVE_SYN and
   TCP_SAVED_SYN options to allow reflection of tos/tclass from received
   SYN packet, from Nikita.

5) Misc improvements to the BPF sockmap test cases in terms of cgroup v2
   interaction and removal of incorrect shutdown() calls, from John.

6) Few cleanups in xdp_umem_assign_dev() and xdpsock samples, from Prashant.

Now that the RCU-bh and RCU-sched update-side functions are simple
wrappers around their RCU counterparts, there isn't a whole lot of
point in testing them.  This commit therefore removes the self-test

58094c48f4 perf annotate: Handle arm64 move instructions 
Add default handler for non-jump instructions.  This really only has an
effect on instructions that compute a PC-relative address, such as
'adrp,' as seen in these couple of examples:

BEFORE: adrp   x0, ffff20000aa11000 <kallsyms_token_index+0xce000>
AFTER:  adrp   x0, kallsyms_token_index+0xce000

BEFORE: adrp   x23, ffff20000ae94000 <__per_cpu_load>
AFTER:  adrp   x23, __per_cpu_load

The implementation is identical to that of s390, but with a slight
adjustment for objdump whitespace propagation (arm64 objdump puts spaces
after commas, whereas s390's presumably doesn't).

The mov__scnprintf() declaration is moved from s390's to arm64's
instructions.c because arm64's gets included before s390's.

Committer testing:

Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff.
