tools/headers: Synchronize kernel ABI headers, v4.16-rc1

2018-02-15T13:01:46+00:00

Sync the following tooling headers with the latest kernel version:

  tools/arch/powerpc/include/uapi/asm/kvm.h
  tools/arch/x86/include/asm/cpufeatures.h
  tools/include/uapi/drm/i915_drm.h
  tools/include/uapi/linux/if_link.h
  tools/include/uapi/linux/kvm.h

All the changes are new ABI additions which don't impact their use
in existing tooling.

====================
pull-request: bpf 2018-02-09

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

The main changes are:

1) Two fixes for BPF sockmap in order to break up circular map references
   from programs attached to sockmap, and detaching related sockets in
   case of socket close() event. For the latter we get rid of the
   smap_state_change() and plug into ULP infrastructure, which will later
   also be used for additional features anyway such as TX hooks. For the
   second issue, dependency chain is broken up via map release callback
   to free parse/verdict programs, all from John.

2) Fix a libbpf relocation issue that was found while implementing XDP
   support for Suricata project. Issue was that when clang was invoked
   with default target instead of bpf target, then various other e.g.
   debugging relevant sections are added to the ELF file that contained
   relocation entries pointing to non-BPF related sections which libbpf
   trips over instead of skipping them. Test cases for libbpf are added
   as well, from Jesper.

3) Various misc fixes for bpftool and one for libbpf: a small addition
   to libbpf to make sure it recognizes all standard section prefixes.
   Then, the Makefile in bpftool/Documentation is improved to explicitly
   check for rst2man being installed on the system as we otherwise risk
   installing empty man pages; the man page for bpftool-map is corrected
   and a set of missing bash completions added in order to avoid shipping
   bpftool where the completions are only partially working, from Quentin.

4) Fix applying the relocation to immediate load instructions in the
   nfp JIT which were missing a shift, from Jakub.

5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y
   gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL
   in this case; and explicitly delete the veth devices in the two tests
   test_xdp_{meta,redirect}.sh before dismantling the netnses as when
   selftests are run in batch mode, then workqueue to handle destruction
   might not have finished yet and thus veth creation in next test under
   same dev name would fail, from Yonghong.

6) Fix test_kmod.sh to check the test_bpf.ko module path before performing
   an insmod, and fallback to modprobe. Especially the latter is useful
   when having a device under test that has the modules installed instead,
   from Naresh.

bpf: Sync kernel ABI header with tooling header for bpf_common.h

2018-02-08T23:24:38+00:00

I recently fixed up a lot of commits that forgot to keep the tooling
headers in sync.  And then I forgot to do the same thing in commit
cb5f7334d479 ("bpf: add comments to BPF ld/ldx sizes"). Let correct
that before people notice ;-).

Lawrence did partly fix/sync this for bpf.h in commit d6d4f60c3a09
("bpf: add selftest for tcpbpf").

tools headers: Sync {tools/,}arch/powerpc/include/uapi/asm/kvm.h

2018-02-02T20:04:53+00:00

The changes in the 3214d01f139b ("KVM: PPC: Book3S: Provide information
about hardware/firmware CVE workarounds") commit right now will not
produce any change in the tools, but that is because we still need to
improve tools/perf/trace/beauty/kvm_ioctl.sh to build per arch string
tables, so that we avoid assigning multiple times to the same command
string entry, i.e. multiple defines, for different arches, have the same
value, causing this:

  In file included from trace/beauty/ioctl.c:82:0:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c: In function ‘ioctl__scnprintf_kvm_cmd’:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:76:11: error: initialized field overwritten [-Werror=override-init]
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:88:11: note: (near initialization for ‘kvm_ioctl_cmds[165]’)
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:90:11: error: initialized field overwritten [-Werror=override-init]
    [0xa6] = "PPC_GET_SMMU_INFO",
             ^~~~~~~~~~~~~~~~~~~

So the onlye effect of updating the tools/ copy of ppc's kvm.h header
is to silence these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/kvm.h' differs from latest version at 'arch/powerpc/include/uapi/asm/kvm.h'

At some point we should do what we did for the errno tables and create
per-arch string translation tables for the KVM ioctl commands for the
architectures supporting KVM, such as s/390, PowerPC, x86_64 and ARM.

bpf: add selftest for tcpbpf

2018-01-26T00:41:15+00:00

Added a selftest for tcpbpf (sock_ops) that checks that the appropriate
callbacks occured and that it can access tcp_sock fields and that their
values are correct.

Run with command: ./test_tcpbpf_user
Adding the flag "-d" will show why it did not pass.
