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_skb_ecn_set_ce'

Lawrence Brakmo says:

====================
Host Bandwidth Manager is a framework for limiting the bandwidth used
by v2 cgroups. It consists of 1 BPF helper, a sample BPF program to
limit egress bandwdith as well as a sample user program and script to
simplify HBM testing.

The sample HBM BPF program is not meant to be production quality, it is
provided as proof of concept. A lot more information, including sample
runs in some cases, are provided in the commit messages of the individual
patches.

A future patch will add support for reducing TCP's cwnd (we are evaluating
alternatives). Another patch will add support for fair queueing's Earliest
Departure Time. Until then, HBM is better suited for flows supporitng ECN.

In addition, A BPF program to limit ingress bandwidth will be provided in
an upcomming patchset.

Changes from v1 to v2:
* bpf_tcp_enter_cwr can only be called from a cgroup skb egress BPF
program (otherwise load or attach will fail) where we already hold
the sk lock. Also only applies for ESTABLISHED state.
* bpf_skb_ecn_set_ce uses INET_ECN_set_ce()
* bpf_tcp_check_probe_timer now uses tcp_reset_xmit_timer. Can only be
used by egress cgroup skb programs.
* removed load_cg_skb user program.
* nrm bpf egress program checks packet header in skb to determine
ECN value. Now also works for ECN enabled UDP packets.
Using ECN_ defines instead of integers.
* NRM script test program now uses bpftool instead of load_cg_skb

Changes from v2 to v3:
* Changed name from NRM (Network Resource Manager) to HBM (Host
Bandwdith Manager)
* The bpf helper to set ECN ce now checks that the header is writeable
* Removed helper bpf functions that modified TCP state due to a concern
about whether the socket is locked by the current thread.

The program nrm creates a cgroup and attaches a BPF program to the

One still needs to create network traffic. This can be done through

A follow-up patch contains a script to create traffic.

-t <time> Exit after specified seconds (deault is 0)
-w Work conserving flag. cgroup can increase its bandwidth
beyond the rate limit specified while there is available
bandwidth. Current implementation assumes there is only
NIC (eth0), but can be extended to support multiple NICs.
Currrently only supported for egress. Note, this is just
a proof of concept.

bpf: Sample HBM BPF program to limit egress bw

A cgroup skb BPF program to limit cgroup output bandwidth.
It uses a modified virtual token bucket queue to limit average
egress bandwidth. The implementation uses credits instead of tokens.
Negative credits imply that queueing would have happened (this is
a virtual queue, so no queueing is done by it. However, queueing may
occur at the actual qdisc (which is not used for rate limiting).

This implementation uses 3 thresholds, one to start marking packets and
the other two to drop packets:
CREDIT
- <--------------------------|------------------------> +
| | | 0
| Large pkt |
| drop thresh |
Small pkt drop Mark threshold
thresh

The effect of marking depends on the type of packet:
a) If the packet is ECN enabled, then the packet is ECN ce marked.
The current mark threshold is tuned for DCTCP.
c) Else, it is dropped if it is a large packet.

If the credit is below the drop threshold, the packet is dropped.
Note that dropping a packet through the BPF program does not trigger CWR
(Congestion Window Reduction) in TCP packets. A future patch will add
support for triggering CWR.

This BPF program actually uses 2 drop thresholds, one threshold
for larger packets (>= 120 bytes) and another for smaller packets. This
protects smaller packets such as SYNs, ACKs, etc.

The default bandwidth limit is set at 1Gbps but this can be changed by
a user program through a shared BPF map. In addition, by default this BPF
program does not limit connections using loopback. This behavior can be
overwritten by the user program. There is also an option to calculate
some statistics, such as percent of packets marked or dropped, which
the user program can access.

A latter patch provides such a program (hbm.c)

This set is next part of a quest to get rid of the bpf_load

First patch fixes ping invocations, ping localhost defaults
to IPv6 on modern setups. Next load_sock_ops sample is removed
and users are directed towards using bpftool directly.

Patch 4 removes the use of bpf_load from samples which don't
need the auto-attachment functionality at all.

Patch 5 improves symbol counting in libbpf, it's not currently
an issue but it will be when anyone adds a symbol with a long
name. Let's make sure that person doesn't have to spend time
scratching their head and wondering why .a and .so symbol
counts don't match.

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

This commit converts the xdpsock sample application to use the AF_XDP

300 lines of code.

The default ring sizes plus the batch size has been increased and the
size of the umem area has decreased. This so that the sample application
will provide higher throughput. Note also that the shared umem code
has been removed from the sample as this is not supported by libbpf
at this point in time.
