* chacha20poly1305: add __init to selftest helper functions
* chacha20: add independent self test

Tons of improvements all around the board to our cryptography library,
including some performance boosts with how we handle SIMD for small packets.

* send/receive: reduce number of sg entries

This quells a powerpc stack usage warning.

* global: remove non-essential inline annotations

We now allow the compiler to determine whether or not to inline certain
functions, while still manually choosing so for a few performance-critical
sections.

* curve25519: arm: do not modify sp directly
* compat: support neon.h on old kernels
* compat: arch-namespace certain includes
* compat: move simd.h from crypto to compat since it's going upstream

This fixes a decent amount of compat breakage and thumb2-mode breakage
introduced by our move to Zinc.

* crypto: use CRYPTOGAMS license

Rather than using code from OpenSSL, use code directly from AndyP.

* poly1305: rewrite self tests from scratch
* poly1305: switch to donna

This makes our C Poly1305 implementation a bit more intensely tested and also
faster, especially on 64-bit systems. It also sets the stage for moving to a
HACL* implementation when that's ready.

* Kconfig: use new-style help marker
* global: run through clang-format
* uapi: reformat
* global: satisfy check_patch.pl errors
* global: prefer sizeof(*pointer) when possible
* global: always find OOM unlikely

Tons of style cleanups.

* crypto: use unaligned helpers

We now avoid unaligned accesses for generic users of the crypto API.

* crypto: import zinc

More style cleanups and a rearrangement of the crypto routines to fit how this
is going to work upstream. This required some fairly big changes to our build
system, so there may be some build errors we'll have to address in subsequent
snapshots.

* compat: rng_is_initialized made it into 4.19

We therefore don't need it in the compat layer anymore.

* curve25519-hacl64: use formally verified C for comparisons

The previous code had been proved in Z3, but this new code from upstream
KreMLin is directly generated from the F*, which is preferable. The
assembly generated is identical.

* curve25519-x86_64: let the compiler decide when/how to load constants

Small performance boost.

* curve25519-arm: reformat
* curve25519-arm: cleanups from lkml
* curve25519-arm: add spaces after commas
* curve25519-arm: use ordinary prolog and epilogue
* curve25519-arm: do not waste 32 bytes of stack
* curve25519-arm: prefix immediates with #

This incorporates ASM nits from upstream review.

* send: switch handshake stamp to an atomic

Rather than abusing the handshake lock, we're much better off just using
a boring atomic64 for this. It's simpler and performs better. Also, while
we're at it, we set the handshake stamp both before and after the
calculations, in case the calculations block for a really long time waiting
for the RNG to initialize.

* compat: better atomic acquire/release backport

This should fix compilation and correctness on several platforms.

* crypto: move simd context to specific type

This was a suggestion from Andy Lutomirski on LKML.

* chacha20poly1305: selftest: use arrays for test vectors

We no longer have lines so long that they're rejected by SMTP servers.

* qemu: add easy git harness

This makes it a bit easier to use our qemu harness for testing our mainline
integration tree.

* curve25519-x86_64: avoid use of r12

This causes problems with RAP and KERNEXEC for PaX, as r12 is a
reserved register.

* chacha20: use memmove in case buffers overlap

A small correctness fix that we never actually hit in WireGuard but is
important especially for moving this into a general purpose library.

* curve25519-hacl64: simplify u64_eq_mask
* curve25519-hacl64: correct u64_gte_mask

Two bitmath fixes from Samuel, which come complete with a z3 script proving
their correctness.

* timers: include header in right file

This fixes compilation in some environments.

* netlink: don't start over iteration on multipart non-first allowedips

Matt Layher found a bug where a netlink dump of peers would never terminate in
some circumstances, causing wg(8) to keep trying forever. We now have a fix as
well as a unit test to mitigate this, and we'll be looking to create a fuzzer
out of Matt's nice library.

Commit 7f694582 introduced a bug where default_postinst() often fails to
remove a uci-defaults script after application, leaving it to run again
after a reboot.
(Note: commit 7f694582 also introduced FS#1021, now fixed by 73c745f6

)

The subtle problem arises from the shell logical chain:
[ -f "$i" ] && . "$i" && rm -f "$i"

Most uci-defaults scripts contain a terminal 'exit 0' statement which,
when sourced, results in the logic chain exiting before executing 'rm -f'.
This was observed while testing upgrades of 'luci-app-sqm'.

The solution is to wrap the shell sourcing in a subshell relative to the
command 'rm -f':
( [ -f "$i" ] && . "$i" ) && rm -f "$i"

Revert to using 'grep' to prefilter the list of entries from the control
file, which yields the full path of uci-defaults scripts. This allows
keeping the existence check, directory change and script sourcing inside
the subshell, with the script removal correctly outside.

This approach avoids adding a second subshell only around the "." (source)
command. The change also preserves the fix FS#1021, since the full path is
used to source the script, which is POSIX-portable irrespective of PATH
variable or reference to the CWD.

Run Tested on: LEDE 17.01.4 running ar71xx, while tracing installation of
package luci-app-sqm with its associated /etc/uci-defaults/luci-sqm file.

Backport an additional patch from 4.16 for nftables.

Fixes: f57806b5

 ("kernel: generic: Fix nftables inet table breakage")
Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
(backported from efffba34)

Commit b7265c59 ("kernel: backport a series of netfilter cleanup
patches to 4.14") added patch 302-netfilter-nf_tables_inet-don-t-use-
multihook-infrast.patch.  That patch switches the netfilter core in the
kernel to use the new native NFPROTO_INET support.  Unfortunately, the
new native NFPROTO_INET support does not exist in 4.14 and was not
backported along with this patchset.  As such, nftables inet tables never
see any traffic.

As an example the following nft counter rule should increment for every
packet coming into the box, but never will:

nft add table inet foo
nft add chain inet foo bar { type filter hook input priority 0\; }
nft add rule inet foo bar counter

This commit pulls in the required backport patches to add the new
native NFPROTO_INET support, and thus restore nftables inet table
functionality.

Tested on Turris Omnia (mvebu)

As of version 4.21, strace enforces mpers by default. The current
implementation of aarch64 compat in strace assumes it's identical to
ARMv7 EABI and therefore tries to enable m32 personality support. As
there is no -m32 support on aarch64, this causes the build to fail.

OpenWrt used to ship hardcoded defaults for lcp-echo-failure and
lcp-echo-interval in the non-uci /etc/ppp/options file.

These values break uci support for *disabling* LCP echos through
the use of "option keepalive 0" as either omitting the keepalive
option or setting it to 0 will result in no lcp-echo-* flags
getting passed to the pppd cmdline, causing the pppd process to
revert to the defaults in /etc/ppp/options.

Address this issue by letting the uci "keepalive" option default
to the former hardcoded values "5, 1" and by removing the fixed
lcp-echo-failure and lcp-echo-interval settings from the
/etc/ppp/options files.
