Changes v5->v6, along with who suggested it.
--------------------------------------------
- [Eric Biggers] Cleaner and more efficient blake2s_final function.
- [Eric Biggers] Remove modulo trick that was working around a gcc 8.1 bug.
- [Eric Biggers] Use crypto_xor_cpy to avoid a memmove in chacha20.
- In the unlikely condition that we transition from SIMD back to scalar
instructions for Poly1305, it's important that we also convert back
from base 2^26 to 2^64. This is super rare and weird, and it's hard
to imagine somebody actually doing this for whatever bad reason, but
it is a possibility, so we shouldn't calculate things wrong in that
instance.
- [Andrew Lunn] Change BUG_ON to WARN_ON in choice places.
- [Thomas Gleixner] Explicitly dual license files under X where X≠GPL2
to be under X && GPL2.
- [Andy Lutomirski] Use separate symbols for selftests that are of
variable length, so that we neither waste space on disk nor waste space
in memory (via __initconst).
- [Thomas Gleixner] Make SPDX headers a standalone comment, and use the
// commenting style in .h files, per the kernel style guide.
- [Paul Burton] Allow assembler to fill branch delay slots on MIPS32r2,
so that the implementation is more future-proof.
- [Eric Biggers] Use Eric's scalar implementation for ChaCha20 ARM, which
performs very well for Cortex-A7,5 and ARMv6, while using Andy
Polyakov's NEON implementation for other ARMv7.
- [Ard Biesheuvel] Reduce optimization from -O3 to -O2.
- [Arn?d Bi?e(rgmann|shuvel)] Make sure stack frames stay inside 1024
bytes on 32-bit and 1280 bytes on 64-bit.
- [Ard Biesheuvel] CRYPTOGAMS-related commit messages now have the
corresponding OpenSSL commit written in them.
- [Eric Biggers] Keep HChaCha20 key in native endian, since in some
cases it can trivially be passed into the ChaCha20 block later.
- Make constants follow a consistent naming scheme.
- Workaround gcc 8 stack mis-optimization on m68k.
- [Arnd Bergmann] Workaround gcc 8 stack mis-optimization with KASAN.
Many of the above ARM changes are a result of discussions between Ard,
Eric, AndyL, AndyP, Samuel, and me. These discussions are ongoing, and so
it's possible we'll do another revision with further ARM tweaks. But perhaps
this one will be sufficient for merging now, and we can continue to refine
later in the cycle.
-----------------------------------------------------------
This patchset is available on git.kernel.org in this branch, where it may be
pulled directly for inclusion into net-next:
* https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux.git/log/?h=jd/wireguard
-----------------------------------------------------------
WireGuard is a secure network tunnel written especially for Linux, which
has faced around three years of serious development, deployment, and
scrutiny. It delivers excellent performance and is extremely easy to
use and configure. It has been designed with the primary goal of being
both easy to audit by virtue of being small and highly secure from a
cryptography and systems security perspective. WireGuard is used by some
massive companies pushing enormous amounts of traffic, and likely
already today you've consumed bytes that at some point transited through
a WireGuard tunnel. Even as an out-of-tree module, WireGuard has been
integrated into various userspace tools, Linux distributions, mobile
phones, and data centers. There are ports in several languages to
several operating systems, and even commercial hardware and services
sold integrating WireGuard. It is time, therefore, for WireGuard to be
properly integrated into Linux.
Ample information, including documentation, installation instructions,
and project details, is available at:
* https://www.wireguard.com/
* https://www.wireguard.com/papers/wireguard.pdf
As it is currently an out-of-tree module, it lives in its own git repo
and has its own mailing list, and every commit for the module is tested
against every stable kernel since 3.10 on a variety of architectures
using an extensive test suite:
* https://git.zx2c4.com/WireGuard
https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/WireGuard.git/
* https://lists.zx2c4.com/mailman/listinfo/wireguard
* https://www.wireguard.com/build-status/
The project has been broadly discussed at conferences, and was presented
to the Netdev developers in Seoul last November, where a paper was
released detailing some interesting aspects of the project. Dave asked
me after the talk if I would consider sending in a v1 "sooner rather
than later", hence this patchset. A decision is still waiting from the
Linux Plumbers Conference, but an update on these topics may be presented
in Vancouver in a few months. Prior presentations:
* https://www.wireguard.com/presentations/
* https://www.wireguard.com/papers/wireguard-netdev22.pdf
The cryptography in the protocol itself has been formally verified by
several independent academic teams with positive results, and I know of
two additional efforts on their way to further corroborate those
findings. The version 1 protocol is "complete", and so the purpose of
this review is to assess the implementation of the protocol. However, it
still may be of interest to know that the thing you're reviewing uses a
protocol with various nice security properties:
* https://www.wireguard.com/formal-verification/
This patchset is divided into four segments. The first introduces a very
simple helper for working with the FPU state for the purposes of amortizing
SIMD operations. The second segment is a small collection of cryptographic
primitives, split up into several commits by primitive and by hardware. The
third shows usage of Zinc within the existing crypto API and as a replacement
to the existing crypto API. The last is WireGuard itself, presented as an
unintrusive and self-contained virtual network driver.
It is intended that this entire patch series enter the kernel through
DaveM's net-next tree. Subsequently, WireGuard patches will go through
DaveM's net-next tree, while Zinc patches will go through Greg KH's tree.
Enjoy,
Jason
Sometimes it's useful to amortize calls to XSAVE/XRSTOR and the related
FPU/SIMD functions over a number of calls, because FPU restoration is
quite expensive. This adds a simple header for carrying out this pattern:
simd_context_t simd_context;
simd_get(&simd_context);
while ((item = get_item_from_queue()) != NULL) {
encrypt_item(item, simd_context);
simd_relax(&simd_context);
}
simd_put(&simd_context);
The relaxation step ensures that we don't trample over preemption, and
the get/put API should be a familiar paradigm in the kernel.
On the other end, code that actually wants to use SIMD instructions can
accept this as a parameter and check it via:
void encrypt_item(struct item *item, simd_context_t *simd_context)
{
if (item->len > LARGE_FOR_SIMD && simd_use(simd_context))
wild_simd_code(item);
else
boring_scalar_code(item);
}
The actual XSAVE happens during simd_use (and only on the first time),
so that if the context is never actually used, no performance penalty is
hit.

2.19.0
Zinc stands for "Zinc Is Neat Crypto" or "Zinc as IN Crypto" or maybe
just "Zx2c4's INsane Cryptolib." It's also short, easy to type, and
plays nicely with the recent trend of naming crypto libraries after
elements. The guiding principle is "don't overdo it". It's less of a
library and more of a directory tree for organizing well-curated direct
implementations of cryptography primitives.
Zinc is a new cryptography API that is much more minimal and lower-level
than the current one. It intends to complement it and provide a basis
upon which the current crypto API might build, as the provider of
software implementations of cryptographic primitives. It is motivated by
three primary observations in crypto API design:
* Highly composable "cipher modes" and related abstractions from
90s cryptographers did not turn out to be as terrific an idea as
hoped, leading to a host of API misuse problems.
* Most programmers are afraid of crypto code, and so prefer to
integrate it into libraries in a highly abstracted manner, so as to
shield themselves from implementation details. Cryptographers, on
the other hand, prefer simple direct implementations, which they're
able to verify for high assurance and optimize in accordance with
their expertise.
* Overly abstracted and flexible cryptography APIs lead to a host of
dangerous problems and performance issues. The kernel is in the
business usually not of coming up with new uses of crypto, but
rather implementing various constructions, which means it essentially
needs a library of primitives, not a highly abstracted enterprise-ready
pluggable system, with a few particular exceptions.
This last observation has seen itself play out several times over and
over again within the kernel:
* The perennial move of actual primitives away from crypto/ and into
lib/, so that users can actually call these functions directly with
no overhead and without lots of allocations, function pointers,
string specifier parsing, and general clunkiness. For example:
sha256, chacha20, siphash, sha1, and so forth live in lib/ rather
than in crypto/. Zinc intends to stop the cluttering of lib/ and
introduce these direct primitives into their proper place, lib/zinc/.
* An abundance of misuse bugs with the present crypto API that have
been very unpleasant to clean up.
* A hesitance to even use cryptography, because of the overhead and
headaches involved in accessing the routines.
Zinc goes in a rather different direction. Rather than providing a
thoroughly designed and abstracted API, Zinc gives you simple functions,
which implement some primitive, or some particular and specific
construction of primitives. It is not dynamic in the least, though one
could imagine implementing a complex dynamic dispatch mechanism (such as
the current crypto API) on top of these basic functions. After all,
dynamic dispatch is usually needed for applications with cipher agility,
such as IPsec, dm-crypt, AF_ALG, and so forth, and the existing crypto
API will continue to play that role. However, Zinc will provide a non-
haphazard way of directly utilizing crypto routines in applications
that do have neither the need nor desire for abstraction and dynamic
dispatch.
It also organizes the implementations in a simple, straight-forward,
and direct manner, making it enjoyable and intuitive to work on.
Rather than moving optimized assembly implementations into arch/, it
keeps them all together in lib/zinc/, making it simple and obvious to
compare and contrast what's happening. This is, notably, exactly what
the lib/raid6/ tree does, and that seems to work out rather well. It's
also the pattern of most successful crypto libraries. The architecture-
specific glue-code is made a part of each translation unit, rather than
being in a separate one, so that generic and architecture-optimized code
are combined at compile-time, and incompatibility branches compiled out by
the optimizer.
All implementations have been extensively tested and fuzzed, and are
selected for their quality, trustworthiness, and performance. Wherever
possible and performant, formally verified implementations are used,
such as those from HACL* [1] and Fiat-Crypto [2]. The routines also take
special care to zero out secrets using memzero_explicit (and future work
is planned to have gcc do this more reliably and performantly with
compiler plugins). The performance of the selected implementations is
state-of-the-art and unrivaled on a broad array of hardware, though of
course we will continue to fine tune these to the hardware demands
needed by kernel contributors. Each implementation also comes with
extensive self-tests and crafted test vectors, pulled from various
places such as Wycheproof [9].
Regularity of function signatures is important, so that users can easily
"guess" the name of the function they want. Though, individual
primitives are oftentimes not trivially interchangeable, having been
designed for different things and requiring different parameters and
semantics, and so the function signatures they provide will directly
reflect the realities of the primitives' usages, rather than hiding it
behind (inevitably leaky) abstractions. Also, in contrast to the current
crypto API, Zinc functions can work on stack buffers, and can be called
with different keys, without requiring allocations or locking.
SIMD is used automatically when available, though some routines may
benefit from either having their SIMD disabled for particular
invocations, or to have the SIMD initialization calls amortized over
several invocations of the function, and so Zinc utilizes function
signatures enabling that in conjunction with the recently introduced
simd_context_t.
More generally, Zinc provides function signatures that allow just what
is required by the various callers. This isn't to say that users of the
functions will be permitted to pollute the function semantics with weird
particular needs, but we are trying very hard not to overdo it, and that
means looking carefully at what's actually necessary, and doing just that,
and not much more than that. Remember: practicality and cleanliness rather
than over-zealous infrastructure.
Zinc provides also an opening for the best implementers in academia to
contribute their time and effort to the kernel, by being sufficiently
simple and inviting. In discussing this commit with some of the best and
brightest over the last few years, there are many who are eager to
devote rare talent and energy to this effort.
Following the merging of this, I expect for the primitives that
currently exist in lib/ to work their way into lib/zinc/, after intense
scrutiny of each implementation, potentially replacing them with either
formally-verified implementations, or better studied and faster
state-of-the-art implementations.
Also following the merging of this, I expect for the old crypto API
implementations to be ported over to use Zinc for their software-based
implementations.
As Zinc is simply library code, its config options are un-menued, with
the exception of CONFIG_ZINC_DEBUG, which enables various selftests and
BUG_ONs.

2.19.0
This provides SSSE3, AVX-2, AVX-512F, and AVX-512VL implementations for
ChaCha20. The AVX-512F implementation is disabled on Skylake, due to
throttling, and the VL ymm implementation is used instead. These come
from Andy Polyakov's implementation, with the following modifications
from Samuel Neves:
- Some cosmetic changes, like renaming labels to .Lname, constants,
and other Linux conventions.
- CPU feature checking is done in C by the glue code, so that has been
removed from the assembly.
- Eliminate translating certain instructions, such as pshufb, palignr,
vprotd, etc, to .byte directives. This is meant for compatibility
with ancient toolchains, but presumably it is unnecessary here,
since the build system already does checks on what GNU as can
assemble.
- When aligning the stack, the original code was saving %rsp to %r9.
To keep objtool happy, we use instead the DRAP idiom to save %rsp
to %r10:
leaq 8(%rsp),%r10
... code here ...
leaq -8(%r10),%rsp
- The original code assumes the stack comes aligned to 16 bytes. This
is not necessarily the case, and to avoid crashes,
`andq $-alignment, %rsp` was added in the prolog of a few functions.
- The original hardcodes returns as .byte 0xf3,0xc3, aka "rep ret".
We replace this by "ret". "rep ret" was meant to help with AMD K8
chips, cf. http://repzret.org/p/repzret. It makes no sense to
continue to use this kludge for code that won't even run on ancient
AMD chips.
While this is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit cded951378069a478391843f5f8653c1eb5128da

2.19.0
These port and prepare Andy Polyakov's implementations for the kernel,
but don't actually wire up any of the code yet. The wiring will be done
in a subsequent commit, since we'll need to merge these implementations
with another one. We make a few small changes to the assembly:
- Entries and exits use the proper kernel convention macro.
- CPU feature checking is done in C by the glue code, so that has been
removed from the assembly.
- The function names have been renamed to fit kernel conventions.
- Labels have been renamed (prefixed with .L) to fit kernel conventions.
- Constants have been rearranged so that they are closer to the code
that is using them. [ARM only]
- The neon code can jump to the scalar code when it makes sense to do
so.
- The neon_512 function as a separate function has been removed, leaving
the decision up to the main neon entry point. [ARM64 only]

These NEON and non-NEON implementations come from Andy Polyakov's
implementation, and are included here in raw form without modification,
so that subsequent commits that fix these up for the kernel can see how
it has changed. This awkward commit splitting has been requested for the
ARM[64] implementations in particular.
While this is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit 87cc649f30aaf69b351701875b9dac07c29ce8a2

These two C implementations -- a 32x32 one and a 64x64 one, depending on
the platform -- come from Andrew Moon's public domain poly1305-donna
portable code, modified for usage in the kernel and for usage with
accelerated primitives.

so that subsequent commits that fix these up for the kernel can see how
it has changed. This awkward commit splitting has been requested for the
ARM[64] implementations in particular.
While this is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit 5bb1cd2292b388263a0cc05392bb99141212aa53

+ @ Trivia.
+ @
+ @ Result of multiplication of n-bit number by m-bit number is
+ @ n+m bits wide. However! Even though 2^n is a n+1-bit number,
+ @ m-bit number multiplied by 2^n is still n+m bits wide.
+ @
+ @ Sum of two n-bit numbers is n+1 bits wide, sum of three - n+2,
+ @ and so is sum of four. Sum of 2^m n-m-bit numbers and n-bit
+ @ one is n+1 bits wide.
+ @
+ @ >>+ denotes Hnext += Hn>>26, Hn &= 0x3ffffff. This means that
+ @ H0, H2, H3 are guaranteed to be 26 bits wide, while H1 and H4
+ @ can be 27. However! In cases when their width exceeds 26 bits
+ @ they are limited by 2^26+2^6. This in turn means that *sum*
+ @ of the products with these values can still be viewed as sum
+ @ of 52-bit numbers as long as the amount of addends is not a
+ @ power of 2. For example,
+ @
+ @ H4 = H4*R0 + H3*R1 + H2*R2 + H1*R3 + H0 * R4,
+ @
+ @ which can't be larger than 5 * (2^26 + 2^6) * (2^26 + 2^6), or
+ @ 5 * (2^52 + 2*2^32 + 2^12), which in turn is smaller than
+ @ 8 * (2^52) or 2^55. However, the value is then multiplied by
+ @ by 5, so we should be looking at 5 * 5 * (2^52 + 2^33 + 2^12),
+ @ which is less than 32 * (2^52) or 2^57. And when processing
+ @ data we are looking at triple as many addends...
+ @
+ @ In key setup procedure pre-reduced H0 is limited by 5*4+1 and
+ @ 5*H4 - by 5*5 52-bit addends, or 57 bits. But when hashing the
+ @ input H0 is limited by (5*4+1)*3 addends, or 58 bits, while
+ @ 5*H4 by 5*5*3, or 59[!] bits. How is this relevant? vmlal.u32
+ @ instruction accepts 2x32-bit input and writes 2x64-bit result.
+ @ This means that result of reduction have to be compressed upon
+ @ loop wrap-around. This can be done in the process of reduction
+ @ to minimize amount of instructions [as well as amount of
+ @ 128-bit instructions, which benefits low-end processors], but
+ @ one has to watch for H2 (which is narrower than H0) and 5*H4
+ @ not being wider than 58 bits, so that result of right shift
+ @ by 26 bits fits in 32 bits. This is also useful on x86,
+ @ because it allows to use paddd in place for paddq, which
+ @ benefits Atom, where paddq is ridiculously slow.

This MIPS32r2 implementation comes from René van Dorst and me and
results in a nice speedup on the usual OpenWRT targets. The MIPS64
implementation comes from Andy Polyakov results in a nice speedup on
commodity Octeon hardware, and has been modified slightly from the
original:
- The function names have been renamed to fit kernel conventions.
- A comment has been added.
No changes have been made to the actual instructions.
While MIPS64 is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit 947716c1872d210828122212d076d503ae68b928

2.19.0
This contains two formally verified C implementations of the Curve25519
scalar multiplication function, one for 32-bit systems, and one for
64-bit systems whose compiler supports efficient 128-bit integer types.
Not only are these implementations formally verified, but they are also
the fastest available C implementations. They have been modified to be
friendly to kernel space and to be generally less horrendous looking,
but still an effort has been made to retain their formally verified
characteristic, and so the C might look slightly unidiomatic.
The 64-bit version comes from HACL*: https://github.com/project-everest/hacl-star
The 32-bit version comes from Fiat: https://github.com/mit-plv/fiat-crypto

2.19.0
This implementation is the fastest available x86_64 implementation, and
unlike Sandy2x, it doesn't requie use of the floating point registers at
all. Instead it makes use of BMI2 and ADX, available on recent
microarchitectures. The implementation was written by Armando
Faz-Hernández with contributions (upstream) from Samuel Neves and me,
in addition to further changes in the kernel implementation from us.

2.19.0
A while back, I noticed that the crypto and crypto API usage in big_keys
were entirely broken in multiple ways, so I rewrote it. Now, I'm
rewriting it again, but this time using Zinc's ChaCha20Poly1305
function. This makes the file considerably more simple; the diffstat
alone should justify this commit. It also should be faster, since it no
longer requires a mutex around the "aead api object" (nor allocations),
allowing us to encrypt multiple items in parallel. We also benefit from
being able to pass any type of pointer to Zinc, so we can get rid of the
ridiculously complex custom page allocator that big_key really doesn't
need.

- # This function encrypts eight consecutive ChaCha20 blocks by loading
- # the state matrix in AVX registers eight times. As we need some
- # scratch registers, we save the first four registers on the stack. The
- # algorithm performs each operation on the corresponding word of each
- # state matrix, hence requires no word shuffling. For final XORing step
- # we transpose the matrix by interleaving 32-, 64- and then 128-bit
- # words, which allows us to do XOR in AVX registers. 8/16-bit word
- # rotation is done with the slightly better performing byte shuffling,
- # 7/12-bit word rotation uses traditional shift+OR.

- # This function encrypts four consecutive ChaCha20 blocks by loading the
- # the state matrix in SSE registers four times. As we need some scratch
- # registers, we save the first four registers on the stack. The
- # algorithm performs each operation on the corresponding word of each
- # state matrix, hence requires no word shuffling. For final XORing step
- # we transpose the matrix by interleaving 32- and then 64-bit words,
- # which allows us to do XOR in SSE registers. 8/16-bit word rotation is
- # done with the slightly better performing SSSE3 byte shuffling,
- # 7/12-bit word rotation uses traditional shift+OR.

2.19.0
WireGuard is a layer 3 secure networking tunnel made specifically for
the kernel, that aims to be much simpler and easier to audit than IPsec.
Extensive documentation and description of the protocol and
considerations, along with formal proofs of the cryptography, are
available at:
* https://www.wireguard.com/
* https://www.wireguard.com/papers/wireguard.pdf
This commit implements WireGuard as a simple network device driver,
accessible in the usual RTNL way used by virtual network drivers. It
makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of
networking subsystem APIs. It has a somewhat novel multicore queueing
system designed for maximum throughput and minimal latency of encryption
operations, but it is implemented modestly using workqueues and NAPI.
Configuration is done via generic Netlink, and following a review from
the Netlink maintainer a year ago, several high profile userspace
have already implemented the API.
This commit also comes with several different tests, both in-kernel
tests and out-of-kernel tests based on network namespaces, taking profit
of the fact that sockets used by WireGuard intentionally stay in the
namespace the WireGuard interface was originally created, exactly like
the semantics of userspace tun devices. See wireguard.com/netns/ for
pictures and examples.
The source code is fairly short, but rather than combining everything
into a single file, WireGuard is developed as cleanly separable files,
making auditing and comprehension easier. Things are laid out as
follows:
* noise.[ch], cookie.[ch], messages.h: These implement the bulk of the
cryptographic aspects of the protocol, and are mostly data-only in
nature, taking in buffers of bytes and spitting out buffers of
bytes. They also handle reference counting for their various shared
pieces of data, like keys and key lists.
* ratelimiter.[ch]: Used as an integral part of cookie.[ch] for
ratelimiting certain types of cryptographic operations in accordance
with particular WireGuard semantics.
* allowedips.[ch], hashtables.[ch]: The main lookup structures of
WireGuard, the former being trie-like with particular semantics, an
integral part of the design of the protocol, and the latter just
being nice helper functions around the specific hashtables we use.
* device.[ch]: Implementation of functions for the netdevice and for
rtnl, responsible for maintaining the life of a given interface and
wiring it up to the rest of WireGuard.
* peer.[ch]: Each interface has a list of peers, with helper functions
available here for creation, destruction, and reference counting.
* socket.[ch]: Implementation of functions related to udp_socket and
the general set of kernel socket APIs, for sending and receiving
ciphertext UDP packets, and taking care of WireGuard-specific sticky
socket routing semantics for the automatic roaming.
* netlink.[ch]: Userspace API entry point for configuring WireGuard
peers and devices. The API has been implemented by several userspace
tools and network management utility, and the WireGuard project
distributes the basic wg(8) tool.
* queueing.[ch]: Shared function on the rx and tx path for handling
the various queues used in the multicore algorithms.
* send.c: Handles encrypting outgoing packets in parallel on
multiple cores, before sending them in order on a single core, via
workqueues and ring buffers. Also handles sending handshake and cookie
messages as part of the protocol, in parallel.
* receive.c: Handles decrypting incoming packets in parallel on
multiple cores, before passing them off in order to be ingested via
the rest of the networking subsystem with GRO via the typical NAPI
poll function. Also handles receiving handshake and cookie messages
as part of the protocol, in parallel.
* timers.[ch]: Uses the timer wheel to implement protocol particular
event timeouts, and gives a set of very simple event-driven entry
point functions for callers.
* main.c, version.h: Initialization and deinitialization of the module.
* selftest/*.h: Runtime unit tests for some of the most security
sensitive functions.
* tools/testing/selftests/wireguard/netns.sh: Aforementioned testing
script using network namespaces.
This commit aims to be as self-contained as possible, implementing
WireGuard as a standalone module not needing much special handling or
coordination from the network subsystem. I expect for future
optimizations to the network stack to positively improve WireGuard, and
vice-versa, but for the time being, this exists as intentionally
standalone.
We introduce a menu option for CONFIG_WIREGUARD, as well as providing a
verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG.

+ * Documentation
+ * =============
+ *
+ * The below enums and macros are for interfacing with WireGuard, using generic
+ * netlink, with family WG_GENL_NAME and version WG_GENL_VERSION. It defines two
+ * methods: get and set. Note that while they share many common attributes,
+ * these two functions actually accept a slightly different set of inputs and
+ * outputs.
+ *
+ * WG_CMD_GET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST | NLM_F_DUMP. The command should contain
+ * one but not both of:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+ *
+ * The kernel will then return several messages (NLM_F_MULTI) containing the
+ * following tree of nested items:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+ * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN
+ * WGDEVICE_A_PUBLIC_KEY: len WG_KEY_LEN
+ * WGDEVICE_A_LISTEN_PORT: NLA_U16
+ * WGDEVICE_A_FWMARK: NLA_U32
+ * WGDEVICE_A_PEERS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+ * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN
+ * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
+ * WGPEER_A_LAST_HANDSHAKE_TIME: struct timespec
+ * WGPEER_A_RX_BYTES: NLA_U64

+ * It is possible that all of the allowed IPs of a single peer will not
+ * fit within a single netlink message. In that case, the same peer will
+ * be written in the following message, except it will only contain
+ * WGPEER_A_PUBLIC_KEY and WGPEER_A_ALLOWEDIPS. This may occur several
+ * times in a row for the same peer. It is then up to the receiver to
+ * coalesce adjacent peers. Likewise, it is possible that all peers will
+ * not fit within a single message. So, subsequent peers will be sent
+ * in following messages, except those will only contain WGDEVICE_A_IFNAME
+ * and WGDEVICE_A_PEERS. It is then up to the receiver to coalesce these
+ * messages to form the complete list of peers.
+ *
+ * Since this is an NLA_F_DUMP command, the final message will always be
+ * NLMSG_DONE, even if an error occurs. However, this NLMSG_DONE message
+ * contains an integer error code. It is either zero or a negative error
+ * code corresponding to the errno.
+ *
+ * WG_CMD_SET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST. The command should contain the
+ * following tree of nested items, containing one but not both of
+ * WGDEVICE_A_IFINDEX and WGDEVICE_A_IFNAME:
+ *
+ * WGDEVICE_A_IFINDEX: NLA_U32
+ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+ * WGDEVICE_A_FLAGS: NLA_U32, 0 or WGDEVICE_F_REPLACE_PEERS if all current
+ * peers should be removed prior to adding the list below.
+ * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN, all zeros to remove
+ * WGDEVICE_A_LISTEN_PORT: NLA_U16, 0 to choose randomly
+ * WGDEVICE_A_FWMARK: NLA_U32, 0 to disable
+ * WGDEVICE_A_PEERS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+ * WGPEER_A_FLAGS: NLA_U32, 0 and/or WGPEER_F_REMOVE_ME if the
+ * specified peer should be removed rather than
+ * added/updated and/or WGPEER_F_REPLACE_ALLOWEDIPS
+ * if all current allowed IPs of this peer should be
+ * removed prior to adding the list below.
+ * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN, all zeros to remove
+ * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16, 0 to disable
+ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
+ * 0: NLA_NESTED
+ * WGALLOWEDIP_A_FAMILY: NLA_U16
+ * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
+ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+ * 1: NLA_NESTED
+ * ...
+ * 2: NLA_NESTED
+ * ...
+ * ...
+ * WGPEER_A_PROTOCOL_VERSION: NLA_U32, should not be set or used at
+ * all by most users of this API, as the
+ * most recent protocol will be used when
+ * this is unset. Otherwise, must be set
+ * to 1.
+ * 1: NLA_NESTED
+ * ...
+ * ...
+ *
+ * It is possible that the amount of configuration data exceeds that of
+ * the maximum message length accepted by the kernel. In that case, several
+ * messages should be sent one after another, with each successive one
+ * filling in information not contained in the prior. Note that if
+ * WGDEVICE_F_REPLACE_PEERS is specified in the first message, it probably
+ * should not be specified in fragments that come after, so that the list
+ * of peers is only cleared the first time but appened after. Likewise for
+ * peers, if WGPEER_F_REPLACE_ALLOWEDIPS is specified in the first message
+ * of a peer, it likely should not be specified in subsequent fragments.
+ *
+ * If an error occurs, NLMSG_ERROR will reply containing an errno.

2.19.0
These wire Andy Polyakov's implementations up to the kernel. We make a
few small changes to the assembly:
- Entries and exits use the proper kernel convention macro.
- CPU feature checking is done in C by the glue code, so that has been
removed from the assembly.
- The function names have been renamed to fit kernel conventions.
- Labels have been renamed to fit kernel conventions.
- The neon code can jump to the scalar code when it makes sense to do
so.

2.19.0
This provides AVX, AVX-2, and AVX-512F implementations for Poly1305.
The AVX-512F implementation is disabled on Skylake, due to throttling.
These come from Andy Polyakov's implementation, with the following
modifications from Samuel Neves:
- Some cosmetic changes, like renaming labels to .Lname, constants,
and other Linux conventions.
- CPU feature checking is done in C by the glue code, so that has been
removed from the assembly.
- poly1305_blocks_avx512 jumped to the middle of the poly1305_blocks_avx2
for the final blocks. To appease objtool, the relevant tail avx2 code
was duplicated for the avx512 function.
- The original uses %rbp as a scratch register. However, the kernel
expects %rbp to be a valid frame pointer at any given time in order
to do proper unwinding. Thus we need to alter the code in order to
preserve it. The most straightforward manner in which this was
accomplished was by replacing $d3, formerly %r10, by %rdi, and
replacing %rbp by %r10. Because %rdi, a pointer to the context
structure, does not change and is not used by poly1305_iteration,
it is safe to use it here, and the overhead of saving and restoring
it should be minimal.
- The original hardcodes returns as .byte 0xf3,0xc3, aka "rep ret".
We replace this by "ret". "rep ret" was meant to help with AMD K8
chips, cf. http://repzret.org/p/repzret. It makes no sense to
continue to use this kludge for code that won't even run on ancient
AMD chips.
While this is CRYPTOGAMS code, the originating code for this happens to
be the same as OpenSSL's commit 4dfe4310c31c4483705991d9a798ce9be1ed1c68

2.19.0
These wire Andy Polyakov's implementations up to the kernel for ARMv7,8
NEON, and introduce Eric Biggers' ultra-fast scalar implementation for
CPUs without NEON or for CPUs with slow NEON (Cortex-A5,7).
This commit does the following:
- Adds the glue code for the assembly implementations.
- Renames the ARMv8 code into place, since it can at this point be
used wholesale.
- Merges Andy Polyakov's ARMv7 NEON code with Eric Biggers' <=ARMv7
scalar code.
Commit note: Eric Biggers' scalar code is brand new, and quite possibly
prematurely added to this commit, and so it may require a bit of revision.
This commit delivers approximately the same or much better performance than
the existing crypto API's code and has been measured to do as such on:
- ARM1176JZF-S [ARMv6]
- Cortex-A7 [ARMv7]
- Cortex-A8 [ARMv7]
- Cortex-A9 [ARMv7]
- Cortex-A17 [ARMv7]
- Cortex-A53 [ARMv8]
- Cortex-A55 [ARMv8]
- Cortex-A73 [ARMv8]
- Cortex-A75 [ARMv8]
Interestingly, Andy Polyakov's scalar code is slower than Eric Biggers',
but is also significantly shorter. This has the advantage that it does
not evict other code from L1 cache -- particularly on ARM11 chips -- and
so in certain circumstances it can actually be faster. However, it wasn't
found that this had an affect on any code existing in the kernel today.

+ * The following scalar routine was written by Eric Biggers.
+ *
+ * Design notes:
+ *
+ * 16 registers would be needed to hold the state matrix, but only 14 are
+ * available because 'sp' and 'pc' cannot be used. So we spill the elements
+ * (x8, x9) to the stack and swap them out with (x10, x11). This adds one
+ * 'ldrd' and one 'strd' instruction per round.
+ *
+ * All rotates are performed using the implicit rotate operand accepted by the
+ * 'add' and 'eor' instructions. This is faster than using explicit rotate
+ * instructions. To make this work, we allow the values in the second and last
+ * rows of the ChaCha state matrix (rows 'b' and 'd') to temporarily have the
+ * wrong rotation amount. The rotation amount is then fixed up just in time
+ * when the values are used. 'brot' is the number of bits the values in row 'b'
+ * need to be rotated right to arrive at the correct values, and 'drot'
+ * similarly for row 'd'. (brot, drot) start out as (0, 0) but we make it such
+ * that they end up as (25, 24) after every round.

I think the -Dpr_fmt is especially odd and not
really acceptable as it not used anywhere else
in the kernel.

There are about 2000 cases in the kernel of the same '#define
pr_fmt...' being pasted into the top of the file, which seems a bit
cumbersome. Rather than having to paste that into each and every file
that I pr_err from, why can't I just do this from the makefile, since
I want that same pr_fmt to copy the whole directory?

Because people like to be able to just read the C file to figure out what it does. Or we could adopt the Makefile approach kernel-wide, since this use of it seems reasonable.

It would indeed be nice to see this done tree-wide. I can recall
various random bugs over the year where some dmesg messages are
missing a prefix because the author forgot to copy and paste the thing
to /yet another file/ in the same directory.

As far as I can tell, zinc doesn't use pr_err, just
pr_info in all the selftest blocks which are only
used when DEBUG is #defined.
Perhaps all the pr_info uses should use pr_debug
instead as well as dynamic debugging which already
optionally adds KBUILD_MODINFO.

Ideally all of those
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
uses will be removed one day soon and the default
will change.
https://lore.kernel.org/patchwork/cover/904507/
This slightly odd use might complicate that.

Yes, pr_info, not pr_err. Apologies for my imprecision. But the
distinction does not matter at all, since they both use pr_fmt in
exactly the same way, which is sufficient for the purposes of this
discussion.

Oh, that's good to see. In this case, I'm prefixing all of them with
zinc: instead of zinc_chacha20: (the modname), but I wouldn't object
to that changing to KBUILD_MODNAME if your patch lands. IOW, once your
patch lands, I'm happy to revisit this discussion and fall back to
using the sane defaults you're in the process of setting up for
everyone.

I'd still prefer as all these are effectively
debugging output that you convert the pr_info
uses pr_debug and so avoid using pr_fmt altogether.

I started to write back, "sure no problem, this will be in v7," but
then I gave it a closer look, and I think actually I'll be changing
these into pr_err/pr_info and not naming this "DEBUG" but rather
"SELFTEST", since I think these are actually very good to have beyond
mere debugging.

Then you should change the CONFIG_ZINC_DEBUG option too.
Dunno what you should do with the
#ifdef DEBUG
BUG_ON(...);
#endif
uses though.

Also, this still has unbounded worst case scheduling latency, given
that the outer library function passes its entire input straight into
the NEON routine.

Good idea. I'll fix that up.

The vast majority of crypto routines in arch/*/crypto/ follow this
same exact pattern, actually. I realize a few don't -- probably the
ones you had a hand in :) -- but I think this is up to the caller to
handle. I made a change so that in chacha20poly1305.c, it calls
simd_relax after handling each scatter-gather element, so a
"construction" will handle this gracefully. But I believe it's up to
the caller to decide on what sizes of information it wants to pass to
primitives. Put differently, this also hasn't ever been an issue
before -- the existing state of the tree indicates this -- and so I
don't anticipate this will be a real issue now. And if it becomes one,
this is something we can address *later*, but certainly there's no use
of adding additional complexity to the initial patchset to do this
now.

Anything that uses the scatterwalk API (AEADs and skciphers) will
handle at most a page at a time. Hashes are different, which is why
some of them have to handle it explicitly.

The state of the tree does not capture all relevant context or
history. The scheduling latency issue was brought up very recently by
the -rt folks on the mailing lists.

You are introducing a very useful SIMD abstraction, but it lets code
run with preemption disabled for unbounded amounts of time, and so now
is the time to ensure we get it right.
Part of the [justified] criticism on the current state of the crypto
API is on its complexity, and so I don't think it makes sense to keep
it simple now and add the complexity later (and the same concern
applies to async support btw).

Hi Jason
This is not my area of expertise, so you should verify what i'm say
here...
My guess is, IPSEC will mostly ask the crypto code to work on 1500
byte full MTU packets and 64 byte TCP ACK packets. Disk encryption i
guess works on 4K blocks. So these requests are all quite small,
keeping the latency reasonably bounded.
The wireguard interface claims it is GSO capable. This means the
network stack will pass it big chunks of data and leave it to the
network interface to perform the segmentation into 1500 byte MTU
frames on the wire. I've not looked at how wireguard actually handles
these big chunks. But to get maximum performance, it should try to
keep them whole, just add a header and/or trailer. Will wireguard pass
these big chunks of data to the crypto code? Do we now have 64K blocks
being worked on? Does the latency jump from 4K to 64K? That might be
new, so the existing state of the tree does not help you here.

No, it only requests GSO superpackets so that it can group the pieces
and encrypt them on the same core. But they're each encrypted
separately (broken up immediately after ndo_start_xmit), and so they
wind up being ~1420 bytes each to encrypt. I spoke about this at
netdev2.2 if you're interested in the architecture; there's a paper:

Ugh, no. I don't want to add needless complexity, period. Zinc is
synchronous, not asynchronous. It provides software implementations.
That's what it does. While many of your reviews have been useful, many
of your comments indicate some desire to change and mold the purpose
and focus of Zinc away from Zinc's intents. Stop that. It's not going
to become a bloated mess of "things Ard wanted and quipped about on
LKML." Things like these only serve to filibuster the patchset
indefinitely. But maybe that's what you'd like all along? Hard to
tell, honestly. So, no, sorry, Zinc isn't gaining an async interface
right now.

Actually, looking at the code again, the abstraction does appear to be
fine, it is just the chacha20 code that does not make use of it.

So what you have in mind is something like calling simd_relax() every
4096 bytes or so?

That was actually pretty easy, putting together both of your suggestions:
static inline bool chacha20_arch(struct chacha20_ctx *state, u8 *dst,
u8 *src, size_t len,
simd_context_t *simd_context)
{
while (len > PAGE_SIZE) {
chacha20_arch(state, dst, src, PAGE_SIZE, simd_context);
len -= PAGE_SIZE;
src += PAGE_SIZE;
dst += PAGE_SIZE;
simd_relax(simd_context);
}
if (IS_ENABLED(CONFIG_KERNEL_MODE_NEON) && chacha20_use_neon &&
len >= CHACHA20_BLOCK_SIZE * 3 && simd_use(simd_context))
chacha20_neon(dst, src, len, state->key, state->counter);
else
chacha20_arm(dst, src, len, state->key, state->counter);
state->counter[0] += (len + 63) / 64;
return true;
}

Hi,
is there documentation and/or rationale for ecn handling?
Quick search for ecn and dscp didn't reveal any.

ECN support was developed with Dave Taht so that it does the right
thing with CAKE and such. He's CC'd, so that he can fill in details,
and sure, we can write these up. As well, I can add the rationale for
the handshake-packet-specific DSCP value to the paper in the next few
days; thanks for pointing out these documentation oversights.

Are, is what you’re saying that the Zinc chacha20 functions should call simd_relax() every n bytes automatically for some reasonable value of n? If so, seems sensible, except that some care might be needed to make sure they interact with preemption correctly.
What I mean is: the public Zinc entry points should either be callable in an atomic context or they should not be. I think this should be checked at runtime in an appropriate place with an __might_sleep or similar. Or simd_relax should learn to *not* schedule if the result of preempt_enable() leaves it atomic. (And the latter needs to be done in a way that works even on non-preempt kernels, and I don’t remember whether that’s possible.). And this should happen regardless of how many bytes are processed. IOW, calling into Zinc should be equally not atomic-safe for 100 bytes and for 10 MB.
As for async, ISTM a really good WireGuard accelerator would expose a different interface than crypto API supports, and it probably makes sense to wait for such hardware to show up before figuring out how to use it. And no matter what form it takes, I don’t think it should complicate the basic Zinc crypto entry points.

Framing it as /needless/ complexity does not help at all. The changes
you are proposing are very useful, but nobody wants two crypto
subsystems with two different maintainers in the kernel, so I would
like to understand where this is going in the future. I am not saying
it should block these patches though.
Also, I have spent a *lot* of time looking at your code, and trying to
make it better, especially for use cases that weren't on your radar to
begin with (e.g., 'pet projects' [your words] like the Cortex-A7 which
will be in almost every new 32-bit Android phone). So characterizing
my feedback as some kind of sabotage is not very productive either.
Contrary to what you seem to think, I am not deeply invested in the
crypto API. What I do care about is that the ARM crypto pieces in the
kernel are maintained, supported and improved by someone who
understands the use cases Linaro's members care about, and is willing
to make an effort to gain such understanding if he doesn't. I have no
doubt that your involvement in the kernel's crypto subsystem will have
a significant positive impact when it comes to code quality,
robustness and usability. I'd just like to see a bit more
consideration for other aspects of kernel programming, e.g.,
preemption under -rt, stack size constraints, coding style, importing
code from other projects etc. - please try to be less dismissive of
feedback first time around, but try to understand why people are
raising these issues; I'm sure you will appreciate it when future
contributors to zinc will do the same.

I'm not sure this is actually a problem. Namely:
preempt_disable();
kernel_fpu_begin();
kernel_fpu_end();
schedule(); <--- bug!
Calling kernel_fpu_end() disables preemption, but AFAIK, preemption
enabling/disabling is recursive, so kernel_fpu_end's use of
preempt_disable won't actually do anything until the outer preempt
enable is called:
preempt_disable();
kernel_fpu_begin();
kernel_fpu_end();
preempt_enable();
schedule(); <--- works!
Or am I missing some more subtle point?

Thanks for clarifying. I understood you to be intending to block the
patches until they were converted to an async interface, which is not
what Zinc's about. Seeing as you're just curious about future
directions, that seems much more tenable.

I am extremely grateful for a good portion of your reviews indeed. As
I mentioned earlier, much is very useful. But in other places, I fear
you're steering this in a direction I really am hesitant to go.

And indeed all of these concerns I've been pretty amenable to, and
continue to do so. What I'm commenting on are things outside of these.

Apologies, and duly noted. I'll give you the benefit of the doubt.

No, I think you’re right. I was mid-remembering precisely how simd_relax() worked.

Can you please stop accusing Ard of "filibustering" your patchset? Spending too
long in non-preemptible code is a real problem even on non-RT systems.
syzkaller has been reporting bugs where the kernel spins too long without any
preemption points, both in crypto-related code and elsewhere in the kernel. So
we've had to add explicit preemption points to address those, as otherwise users
can lock up all CPUs for tens of seconds. The issue being discussed here is
basically the same except here preemption is being explicitly disabled via
kernel_neon_begin(), so it becomes a problem even on non-CONFIG_PREEMPT kernels.
It's much better to address this problem (which is a regression from the current
skcipher API which only maps a page at a time) up front rather than have to rush
to patch it after the fact once the syzbot reports start coming in.

The async distraction (re:filibustering) and the preempt concern are
two totally different things. I've already posted some code elsewhere
in this thread that addresses the preempt issue that looked good to
Ard. This will be part of v7.

As elegant as my quick recursive solution was, gcc produced kind of
bad code from it, as you might expect. So I've implemented this using
a boring old loop that works the way it's supposed to. This is marked
for v7.
Hi Jason
I know you have been concentrating on the crypto code, so i'm not
expecting too many changes at the moment in the network code.
It would be good to further reduce the number of checkpatch warnings.
The biggest problem i have at the moment is that all the trivial to
fix warnings are hiding a few more important warnings. There are a few
like these which are not obvious to see:
WARNING: Avoid crashing the kernel - try using WARN_ON & recovery code rather than BUG() or BUG_ON()
#2984: FILE: drivers/net/wireguard/noise.c:293:
+ BUG_ON(first_len > BLAKE2S_HASH_SIZE || second_len > BLAKE2S_HASH_SIZE ||
WARNING: Macros with flow control statements should be avoided
#5471: FILE: drivers/net/wireguard/selftest/allowedips.h:456:
+#define init_peer(name) do { \
+ name = kzalloc(sizeof(*name), GFP_KERNEL); \
+ if (unlikely(!name)) { \
+ pr_info("allowedips self-test: out of memory\n"); \
+ goto free; \
+ } \
+ kref_init(&name->refcount); \
+ } while (0)
The namespace pollution also needs to be addresses. You have some
pretty generic named global symbols. I picked out a few examples from
objdump
00002a94 g F .text 00000060 peer_put
00003484 g F .text 0000004c timers_stop
00003520 g F .text 00000114 packet_queue_init
00002640 g F .text 00000034 device_uninit
000026bc g F .text 00000288 peer_create
000090d4 g F .text 000001bc ratelimiter_init
Please make use of a prefix for global symbols, e.g. wg_.

Hi Thomas,
I'm trying to optimize this for crypto performance while still taking
into account preemption concerns. I'm having a bit of trouble figuring
out a way to determine numerically what the upper bounds for this
stuff looks like. I'm sure I could pick a pretty sane number that's
arguably okay -- and way under the limit -- but I still am interested
in determining what that limit actually is. I was hoping there'd be a
debugging option called, "warn if preemption is disabled for too
long", or something, but I couldn't find anything like that. I'm also
not quite sure what the latency limits are, to just compute this with
a formula. Essentially what I'm trying to determine is:
preempt_disable();
asm volatile(".fill N, 1, 0x90;");
preempt_enable();
What is the maximum value of N for which the above is okay? What
technique would you generally use in measuring this?
Thanks,
Jason

I would add another consideration: if you can get better latency with negligible overhead (0.1%? 0.05%), then that might make sense too. For example, it seems plausible that checking need_resched() every few blocks adds basically no overhead, and the SIMD helpers could do this themselves or perhaps only ever do a block at a time.
need_resched() costs a cacheline access, but it’s usually a hot cacheline, and the actual check is just whether a certain bit in memory is set.

Yes you're right, I do plan to check quite often, rather than seldom,
for this reason. I've been toying with the idea of instead processing
65k (maximum size of a UDP packet) at a time before checking
need_resched(), but armed with the 20µs figure, this isn't remotely
possible on most hardware. So I'll stick with the original
conservative plan of checking very often, and not making things
different from the aspects worked out by the present crypto API in
this regard.

Why is Herbert Xu's existing crypto tree being circumvented, especially for
future patches (the initial merge isn't quite as important as that's a one-time
event)? I like being able to check out cryptodev to test upcoming crypto
patches. And currently, changes to APIs, algorithms, tests, and implementations
all go through cryptodev, which is convenient for crypto developers.
Apparently, you're proposing that someone adding a new algorithm will now have
to submit the API portion to one maintainer (Herbert Xu) and the implementation
portion to another maintainer (you), and they'll go through separate git trees.
That's inconvenient for developers, and it seems that in practice you and
Herbert will be stepping on each other's toes a lot.
Can you please reach some kind of sane agreement with Herbert so that the
development process isn't fractured into two? Perhaps you could review patches,
but Herbert could still apply them?
I'm also wondering about the criteria for making additions and changes to
"Zinc". You mentioned before that one of the "advantages" of Zinc is that it
doesn't include "cipher modes from 90s cryptographers" -- what does that mean
exactly? You've also indicated before that you don't want people modifying the
Poly1305 implementations as they are too error-prone. Yet apparently it's fine
to change them yourself, e.g. when you added the part that converts the
accumulator from base 26 to base 32. I worry there may be double standards
here, and useful contributions could be blocked or discouraged in the future.
Can you please elaborate on your criteria for contributions to Zinc?
Also, will you allow algorithms that aren't up to modern security standards but
are needed for compatibility reasons, e.g. MD5, SHA-1, and DES? There are
existing standards, APIs, and data formats that use these "legacy" algorithms;
so implementations of them are often still needed, whether we like it or not.
And does it matter who designed the algorithms, e.g. do algorithms from Daniel
Bernstein get effectively a free pass, while algorithms from certain countries,
governments, or organizations are not allowed? E.g. wireless driver developers
may need the SM4 block cipher (which is now supported by the crypto API) as it's
specified in a Chinese wireless standard. Will you allow SM4 in Zinc? Or will
people have to submit some algorithms to Herbert and some to you due to
disagreements about what algorithms should be included?

I think you're overthinking it a bit. Zinc will have a few software
implementations of primitives that are useful in cases where it's nice to call
the primitive directly. Think: various usages of sha2, siphash, the wireguard
suite (what this patchset includes), other things in lib/, etc. In so much as
this winds up duplicating things within the crypto API, I'll work with Herbert
to build one on top of the other -- as I've done in the two commits in this
series. But beyond that, think of the two initiatives as orthogonal. I'm
working on curating a few primitives that are maximally useful throughout
the kernel for various uses, and doing so in a way that I think brings
about a certain quality. Meanwhile the crypto API is amassing a huge
collection of primitives for some things, and that will continue to exist,
and Herbert will continue to maintain that. I expect for the crossover
to be fairly isolated and manageable, without too much foreseeable tree-
conflicts and such. Therefore, Samuel Neves and I plan to maintain the
codebase we've spent quite some time writing, and maintain our own tree for
it, which we'll be submitting through Greg. In other words, this is not
a matter of "circumvention" or "stepping on toes", but rather separate
efforts. I'm quite certain to the extent they overlap we'll be able to work
out fairly easily.
Either way, I'll take your suggestion and reach out to Herbert, since at
least a discussion between the two of us sounds like it could be productive.

Similarly here, I think you're over-politicizing everything. Stable address
generation for IPv6 uses SHA1 -- see net/ipv6/addrconf.c:3203 -- do you think
that this should use, say, the SM3 chinese hash function instead? No, of
course not, for a variety of interesting reasons. Rather, it should use some
simple hash function that's fast in software that we have available in Zinc.
On the other hand, it seems like parts of the kernel that have pretty high-
levels of cipher agility -- such as dmcrypt, ipsec, wifi apparently, and
so on -- will continue to use dynamic-dispatch system like the crypto API,
since that's what it was made to do and is effective at doing. And so, your
example of SM4 seems to fit perfectly into what the crypto API is well-suited
for, and it would fit naturally in there.
In other words, the "political criteria" for what we add to lib/zinc/ will
mostly be the same as for the rest of lib/: are there things using it that
benefit from it being there in a direct and obvious way, and does the
implementation meet certain quality standards.

We do actually appreciate your concern here. However, there's a lot more that
went into that short patch than meets the eye:
- It matches exactly what Andy Polyakov's code is doing for the exact
same reason, so this isn't something that's actually "new". (There
are paths inside his implementation that branch from the vector code
to the scalar code.)
- It has been discussed at length with Andy, including what kinds of
proofs we'll need if we want to chop it down further (to remove that
final reduction), and why we both don't want to do that yet, and so
we go with the full carrying for the avoidance of risk.
- We've proved its correctness with Z3, actually using an even looser
constraint on digit size than what Andy mentioned to us, thus resulting
in a stronger proof result. So we're certain this isn't rubbish.
- There's been some considerable computing power sunk into fuzzing it.
There's no doubt about it, we've done our due-diligence here. This is in
fact the kind of efforts we require of submissions. You could fault us for
not detailing this in "the commit message" -- except as this is still a
patch series, we're putting improvements into the 00/XX change log, instead
of adding fixes and additions on top of the series. Of course in the ordinary
course of kernel development, this would exist instead as a standalone commit.
If you have a better idea of how this kind of thing can be communicated, and
where precisely, in the pre-merge process, I'd be interested in hearing
suggestions.
Thanks,
Jason

I was actually going to ask you about this, because it applies
similarly in another context too that I'm trying to refine. The above
function you quote has the following properties:
- Only ever accepts fixed length parameters, so the compiler can
constant fold invocations of it fantastically. Those parameters are
fixed length in the sense that they're enum/macro constants. They
never come from the user or from a packet or something.
- Never produces an incorrect result. For said constants, all inputs
are valid, and so it succeeds in producing an output every time.
- Is a "pure" function, just knocking bytes around, without needing to
interact with fancy kernel-y things; could be implemented on some sort
of WWII-era rotor machine provided you had the patience.
Because of the above, there's never any error to return to the user of
the function. Also, because it only ever takes constant sized inputs,
in theory I should be able to change that BUG_ON() to BUILD_BUG_ON(),
but in practice the optimizer/inliner isn't actually that aggressive.
But what I would like is some way of signaling to the developer using
this function that they've passed it an illegal value, and their code
should not ship until that's fixed, under any circumstances at all --
that their usage of the function is completely unacceptable and wrong.
Bla bla strong statements.
For this, I figured the notion would come across with the aberrant
behavior of "crash the developer's [in this case, my] QEMU instance"
when "#ifdef DEBUG is true". This is the same kind of place where I'd
have an "assert()" statement in userland. It sounds like what you're
saying is that a WARN_ON is equally as effective instead? Or given the
above, do you think the BUG_ON is actually sensible? Or neither and I
should do something else?

This is part of a debugging selftest, where I'm initing a bunch of
peers one after another, and this macro helps keep the test clear
while offloading the actual irrelevant coding part to this macro. The
test itself then just has code like:
init_peer(a);
init_peer(b);
init_peer(c);
init_peer(d);
init_peer(e);
init_peer(f);
init_peer(g);
init_peer(h);
insert(4, a, 192, 168, 4, 0, 24);
insert(4, b, 192, 168, 4, 4, 32);
insert(4, c, 192, 168, 0, 0, 16);
insert(4, d, 192, 95, 5, 64, 27);
/* replaces previous entry, and maskself is required */
insert(4, c, 192, 95, 5, 65, 27);
insert(6, d, 0x26075300, 0x60006b00, 0, 0xc05f0543, 128);
insert(6, c, 0x26075300, 0x60006b00, 0, 0, 64);
...
And so forth. I can probably figure out a different way to code this
if you really want, but I thought this would be clear.

Will do. v7 will include the wg_ prefix.
On a slightly related note, out of curiosity, any idea what's up with
the future of LTO in the kernel? It sounds like that'd be nice to have
on a module-by-module basis. IOW, I'd love to LTO all of my .c files
in wireguard together, and then only ever expose mod_init/exit and
whatever I explicitly EXPORT_SYMBOL, and then have the compiler and
linker treat the rest of everything as essentially in one .c file and
optimize the heck out of it, and then strip all the symbols. It would,
incidentally, remove the need for said symbol prefixes, since I
wouldn't be making anything global. (Probably perf/ftrace/etc would
become harder to use though.)

So, Zinc will simultaneously replace the current crypto implementations, *and*
be "orthogonal" and "separate" from all the crypto code currently maintained by
Herbert? You can't have your cake and eat it too...
I'm still concerned you're splitting the community in two. It will be unclear
where new algorithms and implementations should go. Some people will choose
Herbert and the current crypto API and conventions, and some people will choose
you and Zinc... I still don't see clear guidelines for what will go where. And
yes, you and Herbert will step on each others' toes and duplicate stuff, as the
efforts are *not* separate, as you've even argued yourself.
Please reach out to Herbert to find a sane solution, ideally one that involves
having a single git tree for crypto development and allows people to continue
crypto development without choosing "sides".

So, crypto implementations and algorithms will go to different maintainers,
source locations, and git trees based purely on whether the current users need
"cipher agility"? Note that usage can change over time; a user that requires a
single cipher could later need multiple, and vice versa.
What if the portion of a wireless driver that needs SM4 doesn't need any other
cipher in the same place, so static dispatch would suffice? Would SM4 be
allowed in Zinc then?

Matches Andy's code, where? The reason you had to add the radix conversion is

Sorry, other people don't know about your private discussions. For the rest of
us, why not add a comment to the code explaining what's going on?

AFAICS actually it *is* rubbish, because your C code stores the accumulator as
64-bit integers whereas the asm code (at least, the 32-bit version) reads it as
32-bit integers. That won't work correctly on big endian ARM.

Apparently not, given that it's broken on big endian ARM.

The details of the correctness proofs and fuzzing you claim to have done aren't
explained, even in the cover letter; so for now we just have to trust you on
that point. Of course, having bugs in code which you insist was proven correct
+ fuzzed doesn't exactly inspire trust.
I understand that your standards are still as high or even higher than
Herbert's, which is good; crypto code should be held to high standards! But
based on the evidence, I do worry there's a double standard going on where you
get away with things yourself which you won't allow from others in Zinc. It's
just not honest, and it will make people not want to contribute to Zinc.
Maintainers are supposed to be unbiased and hold all contributions to the same
standard.
We need "Zinc" to be Linux's crypto library, not "Jason's crypto library".

The plan is for it to replace many uses of the crypto API where it makes
sense, but not replace uses where it doesn't make sense. Perhaps in the
long run, over time, its usage will grow to cover those cases too, or,
perhaps instead, Zinc will form a simple basis of software crypto
algorithms in whatever future API designs crop up. In other words, like
most changes in kernel development, things happen gradually, starting
with a few good cases, and gradually growing as the need and design
arise.

I can try to work out some explicit guidelines and write these up for
Documentation/, if that'd make a difference for you. I don't think this
is a matter of "community splitting". On the contrary, I think Zinc will
bring communities together, inviting the larger cryptography community
to take an interest in improving the state of crypto in Linux. Either
way, the litmus test for where code should go remains pretty similar to
how it's been working so far. Are you tempted to stick it in lib/
because that fits your programming paradigm and because you think it's
generally useful? If so, submit it to lib/zinc/. Conversely, is it only
something used in the large array of options provided by dmcrypt, ipsec,
afalg, etc? Submit it to the crypto API.
If you think this criteria is lacking, I'm amenable to adjusting that
and changing it, especially as situations and designs change and morph
over time. But that seems like a fairly decent starting point.
> Please reach out to Herbert to find a sane solution
> crypto development without choosing "sides".
Please, don't politicize this. This has nothing to do with "sides". This
has to do with which paradigm makes sense for implementing a particular
algorithm. And everything that goes in Zinc gets to be used seamlessly
by the crypto API anyway, through use of the trivial stub glue code,
like what I've shown in the two commits in this series. Again, if it's
something that will work well as a direct function call, then it seems
like Zinc makes sense as a home for it.
With that said, I've reached out to Herbert, and we'll of course discuss
and reach a good conclusion together.
> Note that usage can change over time; a user that requires a
> single cipher could later need multiple, and vice versa.
I think this depends on the design of the driver and the style it's
implemented in. For example, I could imagine something like this:
encrypt_stuff_with_morus(obj, key);
evolving over time to:
if (obj->type == MORUS_TYPE)
encrypt_stuff_with_morus(obj, key);
else if (obj->type == AEGIS_TYPE)
encrypt_stuff_with_aegis(obj, key);
On the other hand, if the developer has good reason to use the crypto
API's dynamic dispatch and async API and so forth, then perhaps it just
changes from:
static const char *cipher_name = "morus";
to
static const char *cipher_name_type_1 = "morus";
static const char *cipher_name_type_2 = "aegis";
I can imagine both programming styles and evolutions being desirable for
different reasons.

For example, check out the avx blocks function. The radix conversion
happens in a few different places throughout. The reason we need it
separately here is because, unlike userspace, it's possible the kernel
code will transition from 2^26 back to 2^64 as a result of the FPU
context changing.
As well, AndyP seems to like the idea of including this logic in the
assembly instead of in C, if I understood our discussions correctly, so
there's a decent chance this will migrate out of the glue code and into
the assembly properly, which is probably a better place for it.

That's a good idea. I can include some discussion about this as well in
the commit message that introduces the glue code, too, I guess? I've
been hesitant to fill these commit messages up even more, given there
are already so many walls of text and whatnot, but if you think that'd
be useful, I'll do that for v7, and also add comments.

What's with the snark? It's not rubbish. I'm not sure if you noticed it in
the development trees (both the WireGuard module tree and my kernel.org
integration tree for this patch), but the big endian ARM support was fixed
pretty shortly after I jumped the gun posting v6. Like, super soon after.
That, and other big endian fixes (on aarch64 as well) are already queued up
for v7. And now build.wireguard.com has more big endian running in CI.

"Claim to have done", "trust you on that point" -- I think there's no
reason to doubt the integrity of my "claims", and I don't appreciate the
phrasing that appears to call that into question.
Regardless, sure, we can expand the "wall-of-text" commit messages even
further, if you want, and include the verbatim Z3 scripts for reproduction.

This is complete and utter garbage, and I find its insinuations insulting
and ridiculous. There is absolutely no lack of honesty and no double
standard being applied whatsoever. Your attempt to cast doubt about the
quality of standards applied and the integrity of the process is wholly
inappropriate. When I tell you that high standards were applied and that
due-diligence was done in developing a particular patch, I mean what I
say.
> We need "Zinc" to be Linux's crypto library, not "Jason's crypto library".
This very much is a project directed toward the benefit of the kernel in
a general sense. It's been this way from the start, and there's nothing
in its goals or plans to the contrary of that. Please leave this vague
and unproductive rhetoric aside.

Please re-read what I wrote. Here I'm talking about the crypto code itself, not
its users.
And you still haven't answered my question about adding a new algorithm that is
useful to have in both APIs. You're proposing that in most cases the crypto API
part will need to go through Herbert while the implementation will need to go
through you/Greg, right? Or will you/Greg be taking both? Or will Herbert take
both?

A documentation file for Zinc is a good idea. Some of the information in your
commit messages should be moved there too.

I'm not trying to "politicize" this, but rather determine your criteria for
including algorithms in Zinc, which you haven't made clear. Since for the
second time you've avoided answering my question about whether you'd allow the
SM4 cipher in Zinc, and you designed WireGuard to be "cryptographically
opinionated", and you were one of the loudest voices calling for the Speck
cipher to be removed, and your justification for Zinc complains about cipher
modes from "90s cryptographers", I think it's reasonable for people to wonder
whether as the Zinc (i.e. Linux crypto library) maintainer you will restrict the
inclusion of crypto algorithms to the ones you prefer, rather than the ones that
users need. Note that the kernel is used by people all over the world and needs
to support various standards, protocols, and APIs that use different crypto
algorithms, not always the ones we'd like; and different users have different
preferences. People need to know whether the Linux kernel's crypto library will
meet (or be allowed to meet) their crypto needs.

IOW, you had to rewrite the x86 assembly algorithm in C and make it use a
different Poly1305 context format. That's a major change, where bugs can be
introduced -- and at least one was introduced, in fact. I'd appreciate it if
you were more accurate in describing your modifications and the potential risks
involved.
And yes I know why converting radixes is needed, as I had pointed it out...

No, I was not aware of the fixed version. I found the bug myself reading the
latest patchset you've mailed out, v6. It's great that you found and fixed this
bug on your own, and of course that raises my level of confidence in your work.
Still, the v6 patchset still includes your claim that "All implementations have
been extensively tested and fuzzed"; so that claim was objectively wrong. So I
disagree that my concerns are "complete and utter garbage". And I think that
the fact that you prefer to respond by attacking me, rather than committing to
be more accurate in your claims and to treat all contributions fairly, is
problematic.
Also, if you have extra tests that you're running, it would be great if you
could include them as part of the submission so that others can run them too.

If an implementation enters Zinc, it will go through my tree. If it
enters the crypto API, it will go through Herbert's tree. If there
wind up being messy tree dependency and merge timing issues, I can
work this out in the usual way with Herbert. I'll be sure to discuss
these edge cases with him when we discuss. I think there's a way to
handle that with minimum friction.

WireGuard is indeed quite opinionated in its primitive choices, but I
don't think it'd be wise to apply the same design to Zinc. There are
APIs where the goal is to have a limited set of high-level functions,
and have those implemented in only a preferred set of primitives. NaCl
is a good example of this -- functions like "crypto_secretbox" that
are actually xsalsapoly under the hood. Zinc doesn't intend to become
an API like those, but rather to provide the actual primitives for use
cases where that specific primitive is used. Sometimes the kernel is
in the business of being able to pick its own crypto -- random.c, tcp
sequence numbers, big_key.c, etc -- but most of the time the kernel is
in the business of implementing other people's crypto, for specific
devices/protocols/diskformats. And for those use cases we need not
some high-level API like NaCl, but rather direct access to the
primitives that are required to implement those drivers. WireGuard is
one such example, but so would be Bluetooth, CIFS/SMB, WiFi, and so
on. We're in the business of writing drivers, after all. So, no, I
don't think I'd knock down the addition of a primitive because of a
simple preference for a different primitive, if it was clearly the
case that the driver requiring it really benefited from having
accessible via the plain Zinc function calls. Sorry if I hadn't made
this clear earlier -- I thought Ard had asked more or less the same
thing about DES and I answered accordingly, but maybe that wasn't made
clear enough there.

A different Poly1305 context format? Not at all - it's using the exact
same context struct as the assembly. And it's making the same
conversion that the assembly is. There's not something "different"
happening; that's the whole point.
Also, this is not some process of frightfully transcribing assembly to
C and hoping it all works out. This is a careful process of reasoning
about the limbs, proving that the carries are correct, and that the
arithmetic done in C actually corresponds to what we want. And then
finally we check that what we've implemented is indeed the same as
what the assembly implemented. Finally, as I mentioned, hopefully Andy
will be folding this back into his implementations sometime soon
anyway.

I believe you have the sequence of events wrong. I've stated and made
that there isn't a double standard, that the standards intend to be
evenly rigorous, and I solicited your feedback on how I could best
communicate changes in pre-merged patch series; I did the things
you've said one should do. But your rhetoric then moved to questioning
my integrity, and I believe that was uncalled for, inappropriate, and
not a useful contribution to this mostly productive discussion --
hence garbage. In other words, I provided an acceptable defense, not
an attack. But can we move past all this schoolyard nonsense? Cut the
rhetoric, please; it's really quite overwhelming.

Good.

I don't think that claim is wrong. The fuzzing and testing that's been
done has been extensive, and the fuzzing and testing that continues to
occur is extensive. As mentioned, the bug was fixed pretty much right
after git-send-email. If you'd like I can try to space out the patch
submissions by a little bit longer -- that would probably have various
benefits -- but given that the netdev code is yet to receive a
thorough review, I think we've got a bit of time before this is
merged. The faster-paced patch cycles might inadvertently introduce
things that get fixed immediately after sending then, unfortunately,
but I don't think this will be the case with the final series that's
merged. Though I'm incorporating tons and tons of feedback right now,
I do look forward to the structure of the series settling down a
little bit and the pace of suggestions decreasing, so that I can focus
on auditing and verifying again. But given the dynamism and
interesting insights of the reviews so far, I think the fast pace has
actually been useful for elucidating the various expectations and
suggestions of reviewers. It's most certainly improved this patchset
in terrific ways.

This expansion of the acronym was intended as a totally ridiculous
joke. I guess it wasn't received well. I'll remove it from the next
series. Sorry.

I would also strongly prefer that all crypto work is taken through
Herbert's tree, so we have a coherent view of it before it goes
upstream.

As I understood from someone who was at your Kernel Recipes talk, you
mentioned that it actually stands for 'zinc is not crypto/' (note the
slash)
That is needlessly divisive and condescending, so if you want to move
past the rhetoric and the schoolyard nonsense, perhaps you can find a
better name for it? Or just put your stuff into crypto/base/,
crypto/core/ or something like that.

Given that this patch applies to all architectures at once, it is
probably better to drop the unrelated reordering hunks to avoid
conflicts.

I mentioned this was in v1 but it wasn't taken as lightly as planned
and was removed, so if it needs a recursive acronym it can be "zinc is
nice crypto", "zinc is neat crypto", or as the commit message
mentions, "zinc as in crypto." Alternatively, it can just not stand
for anything at all. Zinc -> Zinc. That's what the thing is called.

Sure, sounds easy enough.

In case it matters, the motivation for making this a typedef is I
could imagine this at some point turning into a more complicated
struct on certain platforms and that would make refactoring easier. I
could just make it `struct simd_context` now with 1 member though...

The rationale for it being a typedef or moving to a struct now?

Yes just switch to a struct.

Okay. No problem with that, but will wait to hear from Joe first.

We have the above case, and we have the general case. The general case
is, only use BUG_ON() when you know things have already gone bad and
there is no recovery for the machine. I doubt that ever applies to
wireguard. So i expect all the BUG_ON() to be removed. This is
something which Linus keeps ranting about....
In this case:
You have it inside a #ifdef. Meaning you don't really care, you can
keep going anyway if debugging is turned of. So just turn it into a
WARN_ON() so you get the splat, but the kernel keeps running.
You have some other options. first_len, second_len, third_len are all
parameter coming from #defines. As you suggested, you could do
BUILD_BUG_ON(), but you have to do it at the caller. Which is fine,
this is debug code, not user input validation code...
BUILD_BUG_ON(NOISE_HASH_LEN > BLAKE2S_HAS_SIZE)
BUILD_BUG_ON(NOISE_SYMMETRIC_KEY_LEN > BLAKE2S_HAS_SIZE)
BUILD_BUG_ON(NOISE_PUBLIC_KEY_LEN > BLAKE2S_HAS_SIZE)

NOISE_SYMMETRIC_KEY_LEN, 0, NOISE_PUBLIC_KEY_LEN, chaining_key);

Please don't focus on just the examples i give you. Look at the bigger
issue. We cannot see the woods for the trees. checkpatch is giving out
lots of warnings. There are so many, it is hard to see the interesting
ones from the simple ones where you need to add an extra space, or add
missing {}.
If checkpatch was just issues one or two warnings about a goto in a
macro, and nothing else, i probably would let it pass. This is bad,
but it is not terrible. I personally have fallen into a trap caused by
a goto in a macro. I changed the locking, not knowing about the goto,
causing an error path not to unlock the lock. It took a while, but
eventually the error happened, and soon after the machine
deadlocked. At the time static checkers did not expand macros, so they
did not detect the issue.

The namespace is more than just about the linker. I see an Opps stack
trace with wg_ symbols, i know i need to talk to Jason. Without any
prefix, i have to go digging into the code to find out who i need to
talk to. This is one reason why often every symbol has the prefix, not
just the global scope ones. Go look at other code in driver/net. You
will find that most drivers use a prefix everywhere, both local and
global.

Good point. I'll see what the wg_ prefixing looks like for all the
static functions too.

32 *byte* alignment? Is that right? If this is for performance and it

Return values from initcalls are ignored, and given that chacha20 will
be depended upon by random.c, it will never be a module in practice.
Given your previous statement that selftest should *not* be a DEBUG

noisier here imo.
E.g.,

Please drop this SOB line: SOB is not about (co-)authorship but about
who handled the patch on its way into mainline. You are sending the

Note that I am getting bounces from LAKML because the patch is too big.

We're working on that, actually. It's not obvious when it'll be ready
to ship -- perhaps after the initial merge, but perhaps way sooner --
but that is something we're trying to do for arm/arm64/mips64.

Are these CONFIG_ symbols defined anywhere at this point?
In any case, I don't think these is a reason for these, at least not
on ARM/arm64. The 64-bitness is implied in both cases, and the
dependency on !CPU_32v3 you introduce (looking at the version of
Kconfig at the end of the series) seems spurious to me. Was that added
because of some kbuild robot report? (we don't support ARMv3 in the
kernel but ARCH_RPC is built in v3 mode because of historical reasons
while the actual core is a v4)

CRC32 is another case study that I would like to bring up:
- the current status is a bit of a mess, where we treat crc32() and
crc32c() differently - the latter is exposed by libcrc32.ko as a
wrapper around the crypto API, and there is some networking code (SCTP
iirc) that puts another kludge on top of that to ensure that the code
is not used before the module is loaded
- we have C versions, scalar hw instruction based versions and
carryless multiplication based versions for various architectures
- on ST platforms, we have a synchronous hw accelerator that is 10x
faster than C code on the same platform.
AFAICT none of its current users rely on the async interface or
runtime dispatch of the 'hash'.
CRC32/c is an area that I would *really* like to clean up (and am
already doing for arm64) - just having a function call interface would
be a huge improvement but it seems to me that the choice for
monolithic modules per algo/architecture implies that we will have to
leave ST behind in this case.
On the one hand, disregarding this seems fair, at least for the
moment. On the other hand, fixing this in the crypto API, e.g., by
permitting direct function calls to synchronous hashes and without the
need to allocate a transform/request etc, blurs the line even more
where different pieces should live.
Any thoughts?

It was originally this way, I believe, for vmovdqa, which requires
32-byte alignment in vex.256 encoding, and I never removed it after
changing some things. But I'll spend some time ensuring this is so and
if it doesn't make sense anymore it'll be gone by v7. On the other
hand, your suggestion of __cacheline_aligned may actually be something
worth considering, especially on MIPS.

Right, it's for crypto_xor_cpy. Good idea, I'll add the comment.

Okay. It's also there for the other primitives too; I'll nix it for all of them.

That's an excellent idea. We could bloat the whole thing with something like:
#ifdef MODULE
#define WARN_ON_IF_MODULE(x) (x)
#else
#define WARN_ON_IF_MODULE(x) WARN_ON(x)
#endif
But given that kind of thing would probably need to touch more files
in the tree, and hence involve more drawn-out conversation, I'll keep
it as the simple WARN_ON for now. Besides, being noisy no matter what
might actually be the best strategy for receiving bug reports on what
is potentially a pretty catastrophic error.
Thanks for the review.

The s-o-b line is about the DCoO, which is given here by both of us,
with the code starting in a shared tree that only had that s-o-b. I

I was wondering about the ordering of these, actually. I've seen s-o-b
on top and s-o-b on bottom of the cc list in lots of commits and

Yes, they're introduced in the first zinc commit. There's no git-blame
on git.kernel.org, presumably because it's expensive to compute, but
there is on my personal instance, so this might help:

You mean to say that since these nobs are def_bool y and are
essentially "depends on ARM", then I should just straight up use
CONFIG_ARM? I had thought about this, but figured this would make it
easier to later make these optional or have other options block them
need be, or even if the dependencies and requirements for having them
changes (for example, with UML on x86). I think doing it this way
gives us some flexibility later on. So if that's a compelling enough
reason, I'd like to keep those.

I added the !CPU_32v3 in my development tree after posting v6, so good
to hear you're just looking straight at the updated tree. If you see
things jump out in there prior to me posting v7, don't hesitate to let
me know.
The reason it was added was indeed because of:
https://lists.01.org/pipermail/kbuild-all/2018-September/053114.html
-- exactly what you suspected, ARCH_RPC. Have a better suggestion than
!CPU_32v3? It seems to me like so long as the kernel has CPU_32v3 as a
thing in any form, I should mark Zinc as not supporting it, since
we'll certainly be at least v4 and up. (Do you guys have any old Acorn
ARM610 boxes sitting around for old time's sake at LinaroHQ? ;-)

I've added Willy to the CC, as we were actually discussing the crc32
case together two days ago. If my understanding was correct, he seemed
to think it'd be pretty useful too.
It seems like unifying the crc32 implementations at some point would
make sense, and since there's no usage of these as part of the crypto
api, providing crc32 via a vanilla function call seems reasonable.
It's not clear that on some strict formal level, crc32 belongs
anywhere near Zinc, since it's not _exactly_ in the same category...
But one could broaden the scope a bit and make the argument that this
general idea of accepting some bytes, doing some "pure" arithmetic
operations from a particular discipline on them in slightly different
ways depending on the architecture, and then returning some other
bytes, is what in essence is happening with these all of these
function calls, no matter their security or intended use; so if crc32
would benefit from being implemented using the exact same design
patterns, then it might as well be grouped in with the rest of Zinc.
On the other hand, this might be a bit of a slippery slope ("are
compression functions next?"), and a libcrc32.ko could just as well
exist as a standalone thing. I can see it both ways and some other
arguments too, but also this might form a good setting for some much
needed cleanup of the crc32. So that's definitely something we can
consider.
Regarding the synchronous ST driver: I'll give it a thorough read
through, but I do wonder off the bat if actually it'd be possible to
incorporate that into the Zinc paradigm in a fairly non-intrusive way.
I'll give that some thought and play around a bit with it.

Yep, I've had a hard time finding a suitable implementation when I wrote
libslz (deflate+gzip compression). Some were totally inefficient in C,
spending their time negating the value twice for each byte because they
were using the pre-computed tables found in literature, some were using
optimized SIMD and I didn't understand them at all. Finally I spent some
time studying the principle and implemented mine. Later I discovered
that ARMv8 chips have a crc32 instruction for this which is very fast.
I tried it and it works much faster than my C implementation. For me
it's a perfect example of something that could go into a lib like zinc.

Well, it's a hash. Not a cryptographically secure one (32 bits only)
but definitely a hash usable (and used) for many cases. Those who need
a hash could start with SHA2 and figure that they don't need something
that secure since they only use 32 output bits and be fine with CRC32
instead. So that would make sense.

You should avoid suggesting it like this because you may end up
implementing addition :-) You should stick to the initial intent which
is to implement painful and boring stuff like crypto. But when you
see how to implement CRC32, you'll see that it's as painful to
implement as a crypto function. You start with a reference, you're
not satisfied and start to optimize various parts of it until you
break it for some inputs without noticing. I'm pretty sure that it
reminds you your own experience with some crypto functions because
I think we've all been in that situation in this domain.

I was thinking about it as well. There's a relation between crypto
and compression, all transform intelligible information into hidden
one in a reversable way, so the API is quite similar. One could argue
that compression usually requires memory allocation and huge states,
so that's probably not for the same use cases if the functions have
to deal with memory allocations.
In my opinion currently we have :
- asymmetric crypto whose goal is to reversably encrypt/decrypt
in order to protect confidentiality on small data like keys,
or to sign in order to authenticate small data like hashes
- symmetric crypto whose goal is to protect confidentiality on
data blocks.
- hashes whose goal is to provide integrity of data blocks (crc32
fall into this category by the way)
It's visible that despite using similar APIs, compression doesn't
fit into any of these categories.

Having it included could simplify exposing it as a static inline
function when it's a single native instruction on the CPU.
Just my two cents,

Yes, you could just add
asflags-$(CONFIG_CPU_32v3) += -march=armv4
with a comment stating that we don't actually support ARMv3 but only
use it as a code generation target for reasons unrelated to the ISA

AFAIK we only support the StrongARM flavor of RiscPC which is ARMv4.
But yes, some people do care deeply about these antiquated platforms,

of the code.
Anyone is free to submit patches adding code authored by others as
long as the author has made it available under a suitable license, and
this is actually the whole point of the S-o-B: you are stating to the
next guy that the code included in your patch was made available to
you under a compatible license.

Or you could just put the original author as the first S-o-b and then
another (second) S-o-b line where you put yourself as a submitter.
AFAIK, that's how people usually do it.

Alright, I'll do exactly that. Though, if the rationale for this has
to do only with codegen -- with what the C compiler does -- then
shouldn't this be set globally for CONFIG_CPU_32v3? I couldn't find
any macros that test against __LINUX_ARM_ARCH__ being 3 in the
assembly, so this shouldn't be a problem I don't think. Maybe I'll
send a patch.

Why do you need to hear from me again?
As far as I know, the only info about typedef avoidance are in

I personally prefer it with the typedef. If this were my code, I’d say the coding style is silly for opaque tiny structs like this.

Thanks for the clarification.
I've received the SOB directly from the individual in question as it
traveled through an intermediate tree on its way to the tree being
submitted here. Therefore I will retain that SOB so that it shows the
full path.

I don't have any problems with this interface.
However, I'm very unhappy about the fact that this adds another
copy of the chacha20 implementation to the kernel. Either this
is better than the one that we already have or it isn't.
So if it's better please replace the existing chacha20 C
implementation with this or otherwise just adapt the existing
implementation to this interface.
If we're replacing the existing one then you can either replace
it directly within this patch or in a subsequent patch but please
do it in the same series because otherwise we could wind up with
two implementations for years to come.

What is the old column? Is it the existing x86-64 implementation
in the kernel or something else? This needs to be made clear in the
patch description.
The same comment from the previous patch also stands here. Please
ensure that we only have one copy of chacha x86-64 code in the kernel.
Either replace the existing one right here or in a follow-up patch
in the same series.

Indeed this series takes care of removing the other implementation later on.
In case it helps to see things visualized, here's the layout of the
whole series:
https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux.git/log/?h=jd/wireguard
Note that comments on this are probably a bit more useful than on the
version posted to the mailing list, since I've already started
incorporating quite a bit of feedback from v6, and so v7 will be
posted sometime later containing these.

Oh nice, so you did the conversion of the existing crypto code.
I presume someone has done the numbers and verified that there
is no performance regression?
If so it would be good to include those numbers somewhere in this
submission (within a patch description so that it goes into git).

Indeed I've done a pretty ridiculous amount of benchmarking, and the
x86_64 numbers are included in those commits because they're pretty
straightforward to show. The performance is also better on
arm1176,cortex-a7,8,9,15,53,73. On mips, as well, performance is
better, since there wasn't any optimized code there at all. Early
versions of this patchset included a regression on cortex-a7, which
was particularly problematic because Eric Biggers recent fscrypt work
requires fast chacha on that hardware, but this v6 (and the future v7)
contain code that is faster on all platforms across the board.

I agree. I don't have any problems with the zinc code living in
its own git tree. But any upstream merges should definitely go
through the crypto tree because the inherent ties between the two
code-base.

I can send you pull requests then if there are development cycles when
there are in fact relations between the two trees. I'll update the
commit message describing Zinc to include this.

I think all merges should go through the crypto tree so that the
kernel crypto community has oversight over the crypto implementations.

I'll stick with a typedef. Reading the style guide, this clearly falls
into 5.a, 5.b, and maybe 5.c. For 5.a, at some point this will
possibly contain architecture specific blobs. For 5.b, it is just an
enum (integer) right now.

Can you explain why you it is so important to you that your changes
remain outside the crypto tree?
Also, I still think the name Zinc (zinc is not crypto/) is needlessly
divisive and condescending, and unsaying it (in v2 and up) doesn't
really work on the Internet (especially since you are still repeating
it in your conference talk.)

I've been following the drama^Wdiscussion on the zinc for a long time now
and I also think that "zinc" is a misleading name.
Jason, you seem to hate the existing crypto framework with passion,
and the name reflects that.
Since we all agree that the framework can do better and your patches actually
make it better, please just rename it to something that reflects what
it is, a base
framework. I think Ard already suggested "crypto/base/" or "crypto/core/".

I can live with that, but other may still object.
In any case, since you are using the enum member as a bitfield, it
would be better to typedef it to int instead, and retain the enum
definition only for the symbolic constants.

It's not divisive or condescending. I don't hate the existing
framework with a passion -- this is patently false. The name even with
its original acronym doesn't imply anything essentially negative. I
see that you've repeatedly misinterpreted it this way -- which is why
I removed that from v2 for the avoidance of doubt -- but that doesn't
change the fact that its proper interpretation is not a condescending
or divisive one.
Look, people love to bikeshed about names. I'm sure you'll be able to
CC-in a large crew of people who have opinions in one way or another,
and this thread could begin to have many voices on that front or on
multiple fronts. There are real benefits of sticking with the name
I've given to the library I've spent enormous amounts of time writing.
And so I'm going to stick with Zinc, since that's why our library is
called. Sorry. We can talk about this at Plumbers in Vancouver if you
want, but I think you're not going to get very far with a mailing list
naming bikeshed.
Meanwhile, I'm working around the clock to integrate your very useful
technical suggestions, so please keep them coming if you still have
technical nits you'd like to be in v7 of this patchset.

Shouldn't this use the new simd abstraction as well?

I guess qhasm means generated code, right?
Because many of these adds are completely redundant ...

This looks odd as well.
Could you elaborate on what qhasm is exactly? And, as with the other
patches, I would prefer it if we could have your changes as a separate
patch (although having the qhasm base would be preferred)

redundant add
I'll stop here - let me just note that this code does not strike me as
particularly well optimized for in-order cores (such as A7).
For instance, the sequence
vmlal.s32 q2, d18, d7
vmlal.s32 q2, d19, d6
vmlal.s32 q5, d18, d6
vmlal.s32 q5, d19, d21
vmlal.s32 q1, d18, d21
vmlal.s32 q1, d19, d29
vmlal.s32 q0, d18, d28
vmlal.s32 q0, d19, d9
vmlal.s32 q6, d18, d29
vmlal.s32 q6, d19, d28
can be reordered as
vmlal.s32 q2, d18, d7
vmlal.s32 q5, d18, d6
vmlal.s32 q1, d18, d21
vmlal.s32 q0, d18, d28
vmlal.s32 q6, d18, d29
vmlal.s32 q2, d19, d6
vmlal.s32 q5, d19, d21
vmlal.s32 q1, d19, d29
vmlal.s32 q0, d19, d9
vmlal.s32 q6, d19, d28
and not have every other instruction depend on the output of the previous one.
Obviously, the ultimate truth is in the benchmark numbers, but I'd
thought I'd mention it anyway.

Yes.
Please see: http://cr.yp.to/qhasm.html
It generates code from a q-file (the "template").
Actually it is a rather powerful tool, but as you noticed, sometimes
the code is not perfect.

Indeed qhasm converts this --

Yes indeed the output is suboptimal in a lot of places. We can
gradually clean this up -- slowly and carefully over time -- if you
want. I can also look into producing a new implementation within HACL*
so that it's verified. Assurance-wise, though, I feel pretty good
about this implementation considering its origins, its breadth of use
(in BoringSSL), the fuzzing hours it's incurred, and the actual
implementation itself.
Either way, performance-wise, it's really worth having.
For example, on a Cortex-A7, we get these results (according to get_cycles()):
neon: 23142 cycles per call
fiat32: 49136 cycles per call
donna32: 71988 cycles per call
And on a Cortex-A9, we get these results (according to get_cycles()):
neon: 5020 cycles per call
fiat32: 17326 cycles per call
donna32: 28076 cycles per call

By the way, as of a few minutes ago, if you look in the development
tree at the commit called "zinc: Curve25519 ARM implementation", that
now shows the diffs to the original, as you requested. I'll probably
obsess over that a little bit more before v7, but if you see anything
gnarly there beforehand, I'd be happy to hear.

Multiple threads may use the same tfm concurrently, so the tfm context must not
be used to store per-request information such as the IV.

Sorry to ruin the fun, but actually there are no Poly1305 implementations in
CRYPTOGAMS (https://github.com/dot-asm/cryptogams). Nor are there any ChaCha20
implementations.
Andy P., can you please add your Poly1305 and ChaCha20 implementations to the
CRYPTOGAMS repository, so that they have a clear kernel-compatible license?
It would be great if you'd include a kernel-compatible license directly in the
versions in the OpenSSL tree too...
Thanks!

It's not really about the name, though. It's actually about the whole way of
thinking about the submission. Is it a new special library with its own things
going on, or is it just some crypto helper functions? It's really just the
latter, but you've been presenting it as the former, which is causing a lot of
unnecessary confusion and controversy. And I think that largely because you've
started from that perspective, you've ended up with some oddities like your own
directories in lib/ and include/ separate from the other existing crypto helper
functions, and proposals to maintain it completely separately from the existing
crypto code including having a separate git tree and separate upstreaming path.
For example, we already have include/crypto/. What's the difference between
include/crypto/ and include/zinc/? How do users know whether to include e.g.
<crypto/chacha20.h> rather than <zinc/chacha20.h>? And are users going to
remember and understand that "zinc" actually means "crypto" but not really? It
would be much more straightforward and intuitive if we just had
<crypto/chacha20.h>, and your new helper functions were declared in there.
Dismissing these concerns as bikeshedding about the name is missing the point.

"This awkward commit splitting"
Seriously?!?
So you really think it is fine to import huge chunks of code like this
from other projects without keeping track of the local changes?

So was this code taken directly from the OpenSSL project then? If so,
why do the commit messages claim otherwise?

Awkward in the sense that only those two commits are doing it, whereas
the rest of the series is not. Not awkward in any other sense that you
seemed to have divined based on your oversized punctuation below.
Fortunately, at your suggestion for v7, I've now done the splitting
for all of the other places, and so I the comment in the dev tree a
few days ago, since it's now done consistently across the patchset.

Nope. Like much of the net tree, WireGuard can function on ipv6-less
kernels. If you do find something in WireGuard isn't working in a
v6-less configuration, I consider that to be a bug that needs fixing.

OK. I hit a build error yesterday, and setting CONFIG_IPV6 fixed it.
Let me see if I can reproduce.

Nice catch. Looks like the norm is adding "depends on IPV6 || !IPV6"
or the like. I'll play and make sure this works for v7. Thanks for
pointing it out.

No, it really is its own thing with important differences from the
present crypto api. Zinc's focus is on simplicity and clarity. To the
extent that we're at all tangled with the current crypto api, the goal
is to untangle as much as possible. It intends to be a small and
lightweight set of routines, whose relationships are obvious, and with
this direct and to the point organization, as well as work with the larger
cryptography community and with academia to invite collaboration. With
this comes a different way of maintaining it, with higher standards
and a preference for different implementations than the current
situation. With Zinc, you have an obvious series of C function calls
composing the whole thing, without complicated indirection. It's
something that could be trivially lifted out into a userspace library,
and used broadly, for example -- something I'll probably do at some
point. That's a bit of a design change to the current crypto api, and
sprinkling some direct function calls within the current crypto api's
complicated enterprise situation would only kick the can further down
the road, as much complexity would still remain. The goal is to move
away from behemoth enterprise APIs, and large and complex codebases to
a simple and direct way of doing things. This desire to untangle, to
start from a simpler base, and to generally do things differently
means it will go into lib/zinc/ and include/zinc/ and have different
maintainers.

So we will have two competing crypo stacks in the kernel?
Having a lightweight crypto API is a good thing but I really don't like the idea
of having zinc parallel to the existing crypto stack.
And I strongly vote that Herbert Xu shall remain the maintainer of the whole
crypto system (including zinc!) in the kernel.

No, as you've seen in this patchset, the dynamic dispatch crypto API
can trivially be done on top of Zinc. So each time we introduce a new
primitive to Zinc that's also in the dynamic dispatch API, we
reimplement the current crypto API in terms of Zinc. Check out the two
patches in this series that do this; it's quite clean and sleek.

No, sorry, we intend to maintain the code we've written. But I am
amenable to taking a tree-route into upstream based on whatever makes
most sense with merge conflicts and such.

This is why I was asking. Your statement and the code didn't match for me.

So, you will be a sub-maintainer below Herbert's crypto, that's fine.
What you wrote sounded like a parallel world...

For the in-order ARM Cortex-A8 (the target for this code), adjacent
multiply-add instructions forward summands quickly. A simple in-order
dot-product computation has no latency problems, while interleaving
computations, as suggested in this thread, creates problems. Also, on
this microarchitecture, occasional ARM instructions run in parallel with
NEON, so trying to manually eliminate ARM instructions through global
pointer tracking wouldn't gain speed; it would simply create unnecessary
code-maintenance problems.
See https://cr.yp.to/papers.html#neoncrypto for analysis of the
performance of---and remaining bottlenecks in---this code. Further
speedups should be possible on this microarchitecture, but, for anyone
interested in this, I recommend focusing on building a cycle-accurate
simulator (e.g., fixing inaccuracies in the Sobole simulator) first.
Of course, there are other ARM microarchitectures, and there are many
cases where different microarchitectures prefer different optimizations.
The kernel already has boot-time benchmarks for different optimizations
for raid6, and should do the same for crypto code, so that implementors
can focus on each microarchitecture separately rather than living in the
barbaric world of having to choose which CPUs to favor.

Thanks Dan for the insight.
We have already established in a separate discussion that Cortex-A7,
which is main optimization target for future development, does not
have the microarchitectural peculiarity that you are referring to that
ARM instructions are essentially free when interleaved with NEON code.
But I take your point re benchmarking (as I already indicated in my
reply to Jason): if we optimize towards speed, we should ideally reuse
the existing benchmarking infrastructure we have to select the fastest
implementation at runtime. For instance, it turns out that scalar
ChaCha20 is almost as fast as NEON (or even faster?) on A7, and using
NEON in the kernel has some issues of its own.

I've been playing a bit with some code to do this sort of thing,
choosing a set of implementations to enable or disable by trying all the
combinations, and then calculating a quick median. I don't know if I'll
submit that for the initial merge of this patchset -- and in fact all
the current implementations I'm proposing are pretty much okay on
microarchitectures -- but down the line this could be useful as a
mechanism.

you have a speling error (ECM). :)
side note:
I have to say that wireguard works really well with ecn and non-ecn marked flows
against codel and fq_codel on the bottleneck router.
I'd still rather like it if wireguard focused a bit more on
interleaving multiple flows better
rather than on single stream benchmarks, one day.
In this case, codel is managing things not fq and we could possibly
shave a few ms of induced latency off of it in this particular test series:
http://tun.taht.net/~d/wireguard/rrul_-_comcast_v6.png
vs wireguard (doing it ivp6 over that ipv6)
http://tun.taht.net/~d/wireguard/rrul_-_wireguard.png
That said, I've been deploying wireguard widely in replacement of my
old tinc network particularly on machines that were formerly cpu
bottlenecked
and am insanely pleased with it. what's a few extra ms of latency
between friends?

We're working on it, actually. Toke has been running some tests on
some beefy 100gbps hardware he recently acquired, and after v1 lands
we'll probably have a few interesting ideas for this.

Any news on this?
To be clear, question is not about an insignificant documentation
oversight. It is about copying bits from inner packets to outer packets
of a secure* tunnel and documenting it AFAICT nowhere, while claiming
extensive documentation.
* it really should be specified what secure tunnel means, as it has many
plausible interpretations and wireguard surely does not fulfill all of them.
