ASoC: Fixes for v5.1

A few core fixes along with the driver specific ones, mainly fixing
small issues that only affect x86 platforms for various reasons (their
unusual machine enumeration mechanisms mainly, plus a fix for error
handling in topology).

There's some of the driver fixes that look larger than they are, like
the hdmi-codec changes which resulted in an indentation change, and most
of the other large changes are for new drivers like the STM32 changes.

Daniel Borkmann says:

====================
pull-request: bpf-next 2019-03-04

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

The main changes are:

1) Add AF_XDP support to libbpf. Rationale is to facilitate writing
AF_XDP applications by offering higher-level APIs that hide many
of the details of the AF_XDP uapi. Sample programs are converted
over to this new interface as well, from Magnus.

2) Introduce a new cant_sleep() macro for annotation of functions
that cannot sleep and use it in BPF_PROG_RUN() to assert that
BPF programs run under preemption disabled context, from Peter.

3) Introduce per BPF prog stats in order to monitor the usage
of BPF; this is controlled by kernel.bpf_stats_enabled sysctl
knob where monitoring tools can make use of this to efficiently
determine the average cost of programs, from Alexei.

4) Split up BPF selftest's test_progs similarly as we already
did with test_verifier. This allows to further reduce merge
conflicts in future and to get more structure into our
quickly growing BPF selftest suite, from Stanislav.

5) Fix a bug in BTF's dedup algorithm which can cause an infinite
loop in some circumstances; also various BPF doc fixes and
improvements, from Andrii.

6) Various BPF sample cleanups and migration to libbpf in order
to further isolate the old sample loader code (so we can get
rid of it at some point), from Jakub.

7) Add a new BPF helper for BPF cgroup skb progs that allows
to set ECN CE code point and a Host Bandwidth Manager (HBM)
sample program for limiting the bandwidth used by v2 cgroups,
from Lawrence.

8) Enable write access to skb->queue_mapping from tc BPF egress
programs in order to let BPF pick TX queue, from Jesper.

9) Fix a bug in BPF spinlock handling for map-in-map which did
not propagate spin_lock_off to the meta map, from Yonghong.

10) Fix a bug in the new per-CPU BPF prog counters to properly
initialize stats for each CPU, from Eric.

11) Add various BPF helper prototypes to selftest's bpf_helpers.h,
from Willem.

12) Fix various BPF samples bugs in XDP and tracing progs,
from Toke, Daniel and Yonghong.

13) Silence preemption splat in test_bpf after BPF_PROG_RUN()
enforces it now everywhere, from Anders.

14) Fix a signedness bug in libbpf's btf_dedup_ref_type() to
get error handling working, from Dan.

15) Fix bpftool documentation and auto-completion with regards
to stream_{verdict,parser} attach types, from Alban.

Merge branch 'bpf-libbpf-af-xdp'

Magnus Karlsson says:

====================
This patch proposes to add AF_XDP support to libbpf. The main reason
for this is to facilitate writing applications that use AF_XDP by
offering higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.

The proposed interface is composed of two parts:

* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting up umems
and AF_XDP sockets. This interface also loads a simple XDP program
that routes all traffic on a queue up to the AF_XDP socket.

The sample program has been updated to use this new interface and in
that process it lost roughly 300 lines of code. I cannot detect any
performance degradations due to the use of this library instead of the
previous functions that were inlined in the sample application. But I
did measure this on a slower machine and not the Broadwell that we
normally use.

The rings are now called xsk_ring and when a producer operates on
it. It is xsk_ring_prod and for a consumer it is xsk_ring_cons. This
way we can get some compile time error checking that the rings are
used correctly.

Comments and contenplations:

* The current behaviour is that the library loads an XDP program (if
requested to do so) but the clean up of this program is left to the
application. It would be possible to implement this cleanup in the
library, but it would require state to be kept on netdev level,
which there is none at the moment, and the synchronization of this
between processes. All this adding complexity. But when we get an
XDP program per queue id, then it becomes trivial to also remove the
XDP program when the application exits. This proposal from Jesper,
Björn and others will also improve the performance of libbpf, since
most of the XDP program code can be removed when that feature is
supported.

* In a future release, I am planning on adding a higher level data
plane interface too. This will be based around recvmsg and sendmsg
with the use of struct iovec for batching, without the user having
to know anything about the underlying four rings of an AF_XDP
socket. There will be one semantic difference though from the
standard recvmsg and that is that the kernel will fill in the iovecs
instead of the application. But the rest should be the same as the
libc versions so that application writers feel at home.

Patch 1: adds AF_XDP support in libbpf
Patch 2: updates the xdpsock sample application to use the libbpf functions
Patch 3: Documentation update to help first time users

Changes v5 to v6:
* Fixed prog_fd bug found by Xiaolong Ye. Thanks!
Changes v4 to v5:
* Added a FAQ to the documentation
* Removed xsk_umem__get_data and renamed xsk_umem__get_dat_raw to
xsk_umem__get_data
* Replaced the netlink code with bpf_get_link_xdp_id()
* Dynamic allocation of the map sizes. They are now sized after
the max number of queueus on the netdev in question.
Changes v3 to v4:
* Dropped the pr_*() patch in favor of Yonghong Song's patch set
* Addressed the review comments of Daniel Borkmann, mainly leaking
of file descriptors at clean up and making the data plane APIs
all static inline (with the exception of xsk_umem__get_data that
uses an internal structure I do not want to expose).
* Fixed the netlink callback as suggested by Maciej Fijalkowski.
* Removed an unecessary include in the sample program as spotted by
Ilia Fillipov.
Changes v2 to v3:
* Added automatic loading of a simple XDP program that routes all
traffic on a queue up to the AF_XDP socket. This program loading
can be disabled.
* Updated function names to be consistent with the libbpf naming
convention
* Moved all code to xsk.[ch]
* Removed all the XDP program loading code from the sample since
this is now done by libbpf
* The initialization functions now return a handle as suggested by
Alexei
* const statements added in the API where applicable.
Changes v1 to v2:
* Fixed cleanup of library state on error.
* Moved API to initial version
* Prefixed all public functions by xsk__ instead of xsk_
* Added comment about changed default ring sizes, batch size and umem
size in the sample application commit message
* The library now only creates an Rx or Tx ring if the respective
parameter is != NULL

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

The main changes are:

1) Teach verifier dead code removal, this also allows for optimizing /
removing conditional branches around dead code and to shrink the
resulting image. Code store constrained architectures like nfp would

2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
code generation for 32-bit sub-registers. Evaluation shows that this
can result in code reduction of ~5-20% compared to 64 bit-only code
generation. Also add implementation for most JITs, from Jiong.

3) Add support for __int128 types in BTF which is also needed for
vmlinux's BTF conversion to work, from Yonghong.

4) Add a new command to bpftool in order to dump a list of BPF-related
parameters from the system or for a specific network device e.g. in
terms of available prog/map types or helper functions, from Quentin.

5) Add AF_XDP sock_diag interface for querying sockets from user
space which provides information about the RX/TX/fill/completion
rings, umem, memory usage etc, from Björn.

8) Split BPF kselftest's test_verifier into various subgroups of tests
in order better deal with merge conflicts in this area, from Jakub.

9) Add support for queue/stack manipulations in bpftool, from Stanislav.

10) Document BTF, from Yonghong.

11) Dump supported ELF section names in libbpf on program load
failure, from Taeung.

12) Silence a false positive compiler warning in verifier's BTF

Merge branch 'bpftool-probes'

Quentin Monnet says:

====================
Hi,
This set adds a new command to bpftool in order to dump a list of
eBPF-related parameters for the system (or for a specific network
device) to the console. Once again, this is based on a suggestion from
Daniel.

At this time, output includes:

- Availability of bpf() system call
- Availability of bpf() system call for unprivileged users
- JIT status (enabled or not, with or without debugging traces)
- JIT hardening status
- JIT kallsyms exports status
- Global memory limit for JIT compiler for unprivileged users
- Status of kernel compilation options related to BPF features
- Availability of known eBPF program types
- Availability of known eBPF map types
- Availability of known eBPF helper functions

There are three different ways to dump this information at this time:

- Plain output dumps probe results in plain text. It is the most
flexible options for providing descriptive output to the user, but
should not be relied upon for parsing the output.
- JSON output is supported.
- A third mode, available through the "macros" keyword appended to the
command line, dumps some of those parameters (not all) as a series of
"#define" directives, that can be included into a C header file for
example.

Probes for supported program and map types, and supported helpers, are
directly added to libbpf, so that other applications (or selftests) can
reuse them as necessary.

If the user does not have root privileges (or more precisely, the
CAP_SYS_ADMIN capability) detection will be erroneous for most
parameters. Therefore, forbid non-root users to run the command.

v5:
- Move exported symbols to a new LIBBPF_0.0.2 section in libbpf.map
(patches 4 to 6).
- Minor fixes on patches 3 and 4.

v4:
- Probe bpf_jit_limit parameter (patch 2).
- Probe some additional kernel config options (patch 3).
- Minor fixes on patch 6.

v3:
- Do not probe kernel version in bpftool (just retrieve it to probe support
for kprobes in libbpf).
- Change the way results for helper support is displayed: now one list of
compatible helpers for each program type (and C-style output gets a
HAVE_PROG_TYPE_HELPER(prog_type, helper) macro to help with tests. See
patches 6, 7.
- Address other comments from feedback from v2 (please refer to individual
patches' history).

v2 (please also refer to individual patches' history):
- Move probes for prog/map types, helpers, from bpftool to libbpf.
- Move C-style output as a separate patch, and restrict it to a subset of
collected information (bpf() availability, prog/map types, helpers).
- Now probe helpers with all supported program types, and display a list of
compatible program types (as supported on the system) for each helper.
- NOT addressed: grouping compilation options for kernel into subsections
(patch 3) (I don't see an easy way of grouping them at the moment, please
see also the discussion on v1 thread).

tools: bpftool: add probes for eBPF program types

Introduce probes for supported BPF program types in libbpf, and call it
from bpftool to test what types are available on the system. The probe
simply consists in loading a very basic program of that type and see if
the verifier complains or not.

Sample output:

# bpftool feature probe kernel
...

eBPF program_type socket_filter is available
eBPF program_type kprobe is available
eBPF program_type sched_cls is available
...

# bpftool --json --pretty feature probe kernel

...
"program_types": {
"have_socket_filter_prog_type": true,
"have_kprobe_prog_type": true,
"have_sched_cls_prog_type": true,
...
}
}

v5:
- In libbpf.map, move global symbol to a new LIBBPF_0.0.2 section.
- Rename (non-API function) prog_load() as probe_load().

v3:
- Get kernel version for checking kprobes availability from libbpf
instead of from bpftool. Do not pass kernel_version as an argument
when calling libbpf probes.
- Use a switch with all enum values for setting specific program
parameters just before probing, so that gcc complains at compile time
(-Wswitch-enum) if new prog types were added to the kernel but libbpf
was not updated.
- Add a comment in libbpf.h about setrlimit() usage to allow many
consecutive probe attempts.

v2:
- Move probes from bpftool to libbpf.
- Remove C-style macros output from this patch.

14) Packed ring support for virtio, from Tiwei Bie.

15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov.

16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu.

17) Implement coalescing on TCP backlog queue, from Eric Dumazet.

18) Implement carrier change in tun driver, from Nicolas Dichtel.

19) Support msg_zerocopy in UDP, from Willem de Bruijn.

20) Significantly improve garbage collection of neighbor objects when
the table has many PERMANENT entries, from David Ahern.

21) Remove egdev usage from nfp and mlx5, and remove the facility
completely from the tree as it no longer has any users. From Oz
Shlomo and others.

22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
therefore abort the operation before the commit phase (which is the
NETDEV_CHANGEADDR event). From Petr Machata.

23) Add indirect call wrappers to avoid retpoline overhead, and use them
in the GRO code paths. From Paolo Abeni.

24) Add support for netlink FDB get operations, from Roopa Prabhu.

25) Support bloom filter in mlxsw driver, from Nir Dotan.

26) Add SKB extension infrastructure. This consolidates the handling of
the auxiliary SKB data used by IPSEC and bridge netfilter, and is
designed to support the needs to MPTCP which could be integrated in
the future.

27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.
