====================
pull-request: bpf-next 2018-05-17
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Provide a new BPF helper for doing a FIB and neighbor lookup
in the kernel tables from an XDP or tc BPF program. The helper
provides a fast-path for forwarding packets. The API supports
IPv4, IPv6 and MPLS protocols, but currently IPv4 and IPv6 are
implemented in this initial work, from David (Ahern).
2) Just a tiny diff but huge feature enabled for nfp driver by
extending the BPF offload beyond a pure host processing offload.
Offloaded XDP programs are allowed to set the RX queue index and
thus opening the door for defining a fully programmable RSS/n-tuple
filter replacement. Once BPF decided on a queue already, the device
data-path will skip the conventional RSS processing completely,
from Jakub.
3) The original sockmap implementation was array based similar to
devmap. However unlike devmap where an ifindex has a 1:1 mapping
into the map there are use cases with sockets that need to be
referenced using longer keys. Hence, sockhash map is added reusing
as much of the sockmap code as possible, from John.
4) Introduce BTF ID. The ID is allocatd through an IDR similar as
with BPF maps and progs. It also makes BTF accessible to user
space via BPF_BTF_GET_FD_BY_ID and adds exposure of the BTF data
through BPF_OBJ_GET_INFO_BY_FD, from Martin.
5) Enable BPF stackmap with build_id also in NMI context. Due to the
up_read() of current->mm->mmap_sem build_id cannot be parsed.
This work defers the up_read() via a per-cpu irq_work so that
at least limited support can be enabled, from Song.
6) Various BPF JIT follow-up cleanups and fixups after the LD_ABS/LD_IND
JIT conversion as well as implementation of an optimized 32/64 bit
immediate load in the arm64 JIT that allows to reduce the number of
emitted instructions; in case of tested real-world programs they
were shrinking by three percent, from Daniel.
7) Add ifindex parameter to the libbpf loader in order to enable
BPF offload support. Right now only iproute2 can load offloaded
BPF and this will also enable libbpf for direct integration into
other applications, from David (Beckett).
8) Convert the plain text documentation under Documentation/bpf/ into
RST format since this is the appropriate standard the kernel is
moving to for all documentation. Also add an overview README.rst,
from Jesper.
9) Add __printf verification attribute to the bpf_verifier_vlog()
helper. Though it uses va_list we can still allow gcc to check
the format string, from Mathieu.
10) Fix a bash reference in the BPF selftest's Makefile. The '|& ...'
is a bash 4.0+ feature which is not guaranteed to be available
when calling out to shell, therefore use a more portable variant,
from Joe.
11) Fix a 64 bit division in xdp_umem_reg() by using div_u64()
instead of relying on the gcc built-in, from Björn.
12) Fix a sock hashmap kmalloc warning reported by syzbot when an
overly large key size is used in hashmap then causing overflows
in htab->elem_size. Reject bogus attr->key_size early in the
sock_hash_alloc(), from Yonghong.
13) Ensure in BPF selftests when urandom_read is being linked that
--build-id is always enabled so that test_stacktrace_build_id[_nmi]
won't be failing, from Alexei.
14) Add bitsperlong.h as well as errno.h uapi headers into the tools
header infrastructure which point to one of the arch specific
uapi headers. This was needed in order to fix a build error on
some systems for the BPF selftests, from Sirio.
15) Allow for short options to be used in the xdp_monitor BPF sample
code. And also a bpf.h tools uapi header sync in order to fix a
selftest build failure. Both from Prashant.
16) More formally clarify the meaning of ID in the direct packet access
section of the BPF documentation, from Wang.

When waiting for a cacheline to change state in cmpwait, we may immediately
wake-up the first time around the outer loop if the event register was
already set (for example, because of the event stream).
Avoid these spurious wakeups by explicitly clearing the event register
before loading the cacheline and setting the exclusive monitor.

It is probably safe to assume that all Armv8-A implementations have a
multiplier whose efficiency is comparable or better than a sequence of
three or so register-dependent arithmetic instructions. Select
ARCH_HAS_FAST_MULTIPLIER to get ever-so-slightly nicer codegen in the
few dusty old corners which care.
In a contrived benchmark calling hweight64() in a loop, this does indeed
turn out to be a small win overall, with no measurable impact on
Cortex-A57 but about 5% performance improvement on Cortex-A53.

Current Sound is using simple-audio-card which can't support HDMI.
To use HDMI sound, we need to use audio-graph-card.
But, one note is that r8a7795 has 2 HDMI ports, but r8a7796 has 1.
Because of this mismatch, supporting HDMI on salvator-common is
impossible.
Thus, this patch exchange sound card to audio-graph-card and keep
supporting ak4613 as 1st sound node.
r8a7795/r8a7796 salvator-x{s} need to add HDMI sound individually.

This patch increases the ARCH_DMA_MINALIGN to 128 so that it covers the
currently known Cache Writeback Granule (CTR_EL0.CWG) on arm64 and moves
the fallback in cache_line_size() from L1_CACHE_BYTES to this constant.
In addition, it warns (and taints) if the CWG is larger than
ARCH_DMA_MINALIGN as this is not safe with non-coherent DMA.

kvm_read_guest() will eventually look up in kvm_memslots(), which requires
either to hold the kvm->slots_lock or to be inside a kvm->srcu critical
section.
In contrast to x86 and s390 we don't take the SRCU lock on every guest
exit, so we have to do it individually for each kvm_read_guest() call.
Provide a wrapper which does that and use that everywhere.
Note that ending the SRCU critical section before returning from the
kvm_read_guest() wrapper is safe, because the data has been *copied*, so
we don't need to rely on valid references to the memslot anymore.

The following commit:
38b850a730 ("arm64: spinlock: order spin_{is_locked,unlock_wait} against local locks")
... added an smp_mb() to arch_spin_is_locked(), in order
"to ensure that the lock value is always loaded after any other locks have
been taken by the current CPU", and reported one example (the "insane case"
in ipc/sem.c) relying on such guarantee.
It is however understood that spin_is_locked() is not required to provide
such an ordering guarantee (a guarantee that is currently not provided by
all the implementations/archs), and that callers relying on such ordering
should instead insert suitable memory barriers before acting on the result
of spin_is_locked().
Following a recent auditing [1] of the callers of {,raw_}spin_is_locked(),
revealing that none of them are relying on the ordering guarantee anymore,
this commit removes the leading smp_mb() from the primitive thus reverting
38b850a730.

We can trivially save 4 bytes in prologue for cBPF since tail calls
can never be used from there. The register push/pop is pairwise,
here, x25 (fp) and x26 (tcc), so no point in changing that, only
reset to zero is not needed.

Improve the JIT to emit 64 and 32 bit immediates, the current
algorithm is not optimal and we often emit more instructions
than actually needed. arm64 has movz, movn, movk variants but
for the current 64 bit immediates we only use movz with a
series of movk when needed.
For example loading ffffffffffffabab emits the following 4
instructions in the JIT today:
* movz: abab, shift: 0, result: 000000000000abab
* movk: ffff, shift: 16, result: 00000000ffffabab
* movk: ffff, shift: 32, result: 0000ffffffffabab
* movk: ffff, shift: 48, result: ffffffffffffabab
Whereas after the patch the same load only needs a single
instruction:
* movn: 5454, shift: 0, result: ffffffffffffabab
Another example where two extra instructions can be saved:
* movz: abab, shift: 0, result: 000000000000abab
* movk: 1f2f, shift: 16, result: 000000001f2fabab
* movk: ffff, shift: 32, result: 0000ffff1f2fabab
* movk: ffff, shift: 48, result: ffffffff1f2fabab
After the patch:
* movn: e0d0, shift: 16, result: ffffffff1f2fffff
* movk: abab, shift: 0, result: ffffffff1f2fabab
Another example with movz, before:
* movz: 0000, shift: 0, result: 0000000000000000
* movk: fea0, shift: 32, result: 0000fea000000000
After:
* movz: fea0, shift: 32, result: 0000fea000000000
Moreover, reuse emit_a64_mov_i() for 32 bit immediates that
are loaded via emit_a64_mov_i64() which is a similar optimization
as done in 6fe8b9c1f4 ("bpf, x64: save several bytes by using
mov over movabsq when possible"). On arm64, the latter allows to
use a single instruction with movn due to zero extension where
otherwise two would be needed. And last but not least add a
missing optimization in emit_a64_mov_i() where movn is used but
the subsequent movk not needed. With some of the Cilium programs
in use, this shrinks the needed instructions by about three
percent. Tested on Cavium ThunderX CN8890.

Commit 9730348075 ("arm64: Increase the max granular size") increased
the cache line size to 128 to match Cavium ThunderX, apparently for some
performance benefit which could not be confirmed. This change, however,
has an impact on the network packet allocation in certain circumstances,
requiring slightly over a 4K page with a significant performance
degradation. The patch reverts L1_CACHE_SHIFT back to 6 (64-byte cache
line).

It is a bit unorthodox to just include a file in the middle of a another
DTS file, it breaks the pattern from other device trees and also makes
it really hard to reference things across the files with phandles.
Restructure the include for the Juno/RTSM motherboards to happen at the
top of the file, reference the target nodes directly, and indent the
motherboard .dtsi files to reflect their actual depth in the hierarchy.
This is a purely syntactic change that result in the same DTB files from
the DTS/DTSI files. This is based on similar patch from Linus Walleij
for ARM Vexpress platforms.

It is a bit unorthodox to just include a file in the middle of a another
DTS file, it breaks the pattern from other device trees and also makes
it really hard to reference things across the files with phandles.
Restructure the include for the Versatile Express motherboards to happen
at the top of the file, reference the target nodes directly, and indent
the motherboard .dtsi files to reflect their actual depth in the
hierarchy.
This is a purely syntactic change that result in the same DTB files from
the DTS/DTSI files.

This way we have one central definition of it, and user can select it as
needed. The new option is not user visible, which is the behavior
it had in most architectures, with a few notable exceptions:
- On x86_64 and mips/loongson3 it used to be user selectable, but
defaulted to y. It now is unconditional, which seems like the right
thing for 64-bit architectures without guaranteed availablity of
IOMMUs.
- on powerpc the symbol is user selectable and defaults to n, but
many boards select it. This change assumes no working setup
required a manual selection, but if that turned out to be wrong
we'll have to add another select statement or two for the respective
boards.

Most mainstream architectures are using 65536 entries, so lets stick to
that. If someone is really desperate to override it that can still be
done through <asm/dma-mapping.h>, but I'd rather see a really good
rationale for that.
dma_debug_init is now called as a core_initcall, which for many
architectures means much earlier, and provides dma-debug functionality
earlier in the boot process. This should be safe as it only relies
on the memory allocator already being available.

Proxying the cpuif accesses at EL2 makes use of vcpu_data_guest_to_host
and co, which check the endianness, which call into vcpu_read_sys_reg...
which isn't mapped at EL2 (it was inlined before, and got moved OoL
with the VHE optimizations).
The result is of course a nice panic. Let's add some specialized
cruft to keep the broken platforms that require this hack alive.
But, this code used vcpu_data_guest_to_host(), which expected us to
write the value to host memory, instead we have trapped the guest's
read or write to an mmio-device, and are about to replay it using the
host's readl()/writel() which also perform swabbing based on the host
endianness. This goes wrong when both host and guest are big-endian,
as readl()/writel() will undo the guest's swabbing, causing the
big-endian value to be written to device-memory.
What needs doing?
A big-endian guest will have pre-swabbed data before storing, undo this.
If its necessary for the host, writel() will re-swab it.
For a read a big-endian guest expects to swab the data after the load.
The hosts's readl() will correct for host endianness, giving us the
device-memory's value in the register. For a big-endian guest, swab it
as if we'd only done the load.
For a little-endian guest, nothing needs doing as readl()/writel() leave
the correct device-memory value in registers.
Tested on Juno with that rarest of things: a big-endian 64K host.
Based on a patch from Marc Zyngier.

Our out-of-line atomics are built with a special calling convention,
preventing pointless stack spilling, and allowing us to patch call sites
with ARMv8.1 atomic instructions.
Instrumentation inserted by the compiler may result in calls to
functions not following this special calling convention, resulting in
registers being unexpectedly clobbered, and various problems resulting
from this.
For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the
compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of
the atomic functions. This has been observed to result in spurious
cmpxchg failures, leading to a hang early on in the boot process.
This patch avoids such issues by preventing instrumentation of our
out-of-line atomics.

Recently kernelCI reported the board mt7622-rfb1 has a fail test with
kernel: ERROR: did not start booting whose details could be seen at [1].
The cause is that UART0 can't output anything when it's missing a proper
pin setup with current DTS, so the essential driver is always getting
enabled to fix up the issue.

("ARM: multi_v7_defconfig: enable Rockchip io-domain driver"). This
change is also needed for arm64 rockchip boards, so, do the same for arm64.
The io-domain driver is necessary to notify the soc about voltages
changes happening on supplying regulators. Probably the most important
user right now is the mmc tuning code, where the soc needs to get
notified when the voltage is dropped to the 1.8V point.
As this option is necessary to successfully tune UHS cards etc, it
should get built in. Otherwise, tuning will fail with,

Call clear_siginfo to ensure every stack allocated siginfo is properly
initialized before being passed to the signal sending functions.
Note: It is not safe to depend on C initializers to initialize struct
siginfo on the stack because C is allowed to skip holes when
initializing a structure.
The initialization of struct siginfo in tracehook_report_syscall_exit
was moved from the helper user_single_step_siginfo into
tracehook_report_syscall_exit itself, to make it clear that the local
variable siginfo gets fully initialized.
In a few cases the scope of struct siginfo has been reduced to make it
clear that siginfo siginfo is not used on other paths in the function
in which it is declared.
Instances of using memset to initialize siginfo have been replaced
with calls clear_siginfo for clarity.

Our arm64_skip_faulting_instruction() helper advances the userspace
singlestep state machine, but this is also called by the kernel BRK
handler, as used for WARN*().
Thus, if we happen to hit a WARN*() while the user singlestep state
machine is in the active-no-pending state, we'll advance to the
active-pending state without having executed a user instruction, and
will take a step exception earlier than expected when we return to
userspace.
Let's fix this by only advancing the state machine when skipping a user
instruction.

This clashes with commit bd8b22d288 ("Kbuild: kallsyms: ignore veneers

The problem was manifested as 'perf test -vvvvv vmlinux' failed,

Although we've implemented PSCI 0.1, 0.2 and 1.0, we expose either 0.1
or 1.0 to a guest, defaulting to the latest version of the PSCI
implementation that is compatible with the requested version. This is
no different from doing a firmware upgrade on KVM.
But in order to give a chance to hypothetical badly implemented guests
that would have a fit by discovering something other than PSCI 0.2,
let's provide a new API that allows userspace to pick one particular
version of the API.
This is implemented as a new class of "firmware" registers, where
we expose the PSCI version. This allows the PSCI version to be
save/restored as part of a guest migration, and also set to
any supported version if the guest requires it.

Both 32-bit amd 64-bit ARM use the asm-generic header files for their
sysvipc data structures, so no special care is needed to make those
work beyond y2038, with the one exception of compat mode: Since there
is no asm-generic definition of the compat mode IPC structures, ARM64
provides its own copy, and we make those match the changes in the native
asm-generic header files.
There is sufficient padding in these data structures to extend all
timestamps to 64 bit, but on big-endian ARM kernels, the padding
is in the wrong place, so the C library has to ensure it reassembles
a 64-bit time_t correctly.

The USB configuration on GXM is slightly different than on GXL. The dwc3
controller's internal hub has three USB2 ports (instead of 2 on GXL)
along with a dedicated USB2 PHY for this port. However, it seems that
there are no pins on GXM which would allow connecting the third port to
a physical USB port.
Passing the third PHY is required though, because without it none of the
other USB ports is working (this seems to be a limitation of how the
internal USB hub works, if one PHY is disabled then no USB port works).

This adds USB host support to the Meson GXL SoC. A dwc3 controller is
used for host-mode, while a dwc2 controller (not added in this patch
because I could not get it working) is used for device-mode only.
The dwc3 controller's internal roothub has two USB2 ports enabled but no
USB3 port. Each of the ports is supplied by a separate PHY. The USB pins
are connected to the SoC's USBHOST_A and USBOTG_B pins.
Due to the way the roothub works internally the USB PHYs are left
enabled. When the dwc3 controller is disabled the PHY is never powered on
so it does not draw any extra power. However, when the dwc3 host
controller is enabled then all PHYs also have to be enabled, otherwise
USB devices will not be detected (regardless of whether they are plugged
into an enabled port or not). This means that only the dwc3 controller
has to be enabled on boards with USB support (instead of requiring all
boards to enable the PHYs additionally with the chance of forgetting to
enable one and breaking all other ports with that as well).
This also adds the USB3 PHY which currently only does some basic
initialization. That however is required because without it high-speed
devices (like USB thumb drives) do not work on some devices (probably
because the bootloader does not configure the USB3 PHY registers).

Since commit:
a7e6f1ca90 ("arm64: signal: Force SIGKILL for unknown signals in force_signal_inject")
... any signal which is not SIGKILL will be upgraded to a SIGKILL be
force_signal_inject(). This includes signals we do expect, such as
SIGILL triggered by do_undefinstr().
Fix the check to use a logical AND rather than a logical OR, permitting
signals whose layout is SIL_FAULT.

While generating a message about guests probing for SVE/LORegions
is a useful debugging tool, considering it an error is slightly
over the top, as this is the only way the guest can find out
about the presence of the feature.
Let's turn these message into kvm_debug so that they can only
be seen if CONFIG_DYNAMIC_DEBUG, and kept quiet otherwise.
