Pull networking fixes from David Miller:

 1) Sanity check URB networking device parameters to avoid divide by
    zero, from Oliver Neukum.

 2) Disable global multicast filter in NCSI, otherwise LLDP and IPV6
    don't work properly. Longer term this needs a better fix tho. From
    Vijay Khemka.

 3) Small fixes to selftests (use ping when ping6 is not present, etc.)
    from David Ahern.

 4) Bring back rt_uses_gateway member of struct rtable, it's semantics
    were not well understood and trying to remove it broke things. From
    David Ahern.

 5) Move usbnet snaity checking, ignore endpoints with invalid
    wMaxPacketSize. From Bjørn Mork.

 6) Missing Kconfig deps for sja1105 driver, from Mao Wenan.

 7) Various small fixes to the mlx5 DR steering code, from Alaa Hleihel,
    Alex Vesker, and Yevgeny Kliteynik

 8) Missing CAP_NET_RAW checks in various places, from Ori Nimron.

 9) Fix crash when removing sch_cbs entry while offloading is enabled,
    from Vinicius Costa Gomes.

10) Signedness bug fixes, generally in looking at the result given by
    of_get_phy_mode() and friends. From Dan Crapenter.

11) Disable preemption around BPF_PROG_RUN() calls, from Eric Dumazet.

12) Don't create VRF ipv6 rules if ipv6 is disabled, from David Ahern.

13) Fix quantization code in tcp_bbr, from Kevin Yang.

libbpf: Teach btf_dumper to emit stand-alone anonymous enum definitions

2019-09-26T12:38:29+00:00

BTF-to-C converter previously skipped anonymous enums in an assumption
that those are embedded in struct's field definitions. This is not
always the case and a lot of kernel constants are defined as part of
anonymous enums. This change fixes the logic by eagerly marking all
types as either referenced by any other type or not. This is enough to
distinguish two classes of anonymous enums and emit previously omitted
enum definitions.

rbtree: avoid generating code twice for the cached versions (tools copy)

2019-09-26T00:51:39+00:00

As was already noted in rbtree.h, the logic to cache rb_first (or
rb_last) can easily be implemented externally to the core rbtree api.

This commit takes the changes applied to the include/linux/ and lib/
rbtree files in 9f973cb38088 ("lib/rbtree: avoid generating code twice
for the cached versions"), and applies these to the
tools/include/linux/ and tools/lib/ files as well to keep them
synchronized.

libbpf: fix false uninitialized variable warning

2019-09-25T20:15:02+00:00

Some compilers emit warning for potential uninitialized next_id usage.
The code is correct, but control flow is too complicated for some
compilers to figure this out. Re-initialize next_id to satisfy
compiler.

libtraceevent: Move traceevent plugins in its own subdirectory

2019-09-25T12:51:43+00:00

All traceevent plugins code is moved to tools/lib/traceevent/plugins
subdirectory. It makes traceevent implementation in trace-cmd and in
kernel tree consistent. There is no changes in the way libtraceevent and
plugins are compiled and installed.

Committer notes:

Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf
target for the plugin dynamic list file. Problem noticed when cross
building to aarch64 from a Ubuntu 19.04 container.

libtraceevent: Add tep_get_event() in event-parse.h

2019-09-25T12:51:43+00:00

The tep_get_event() function is an official libtracevent API, described
in the library man pages. However, it cannot be used by the library users because
it is not declared in the event-parse.h file, where all libtracevent APIs are.
The function declaration is added in event-parse.h file.

libtraceevent: Man pages fix, changes in event printing APIs

2019-09-25T12:51:43+00:00

APIs for printing various trace event information were redesigned to be
more simple. However, the main libtraceevent man page was not updated
with those changes. The documentation is updated to describe the new
event print API.

libtraceevent: Man pages fix, rename tep_ref_get() to tep_get_ref()

2019-09-25T12:51:43+00:00

The tep_ref_get() was renamed to tep_get_ref(), to be more consistent
with the other tep_ref_* APIs. However, in the man pages the API is
still with the old name. The documentation is fixed to reflect the
actual name of the API.
