+Subject: [PATCH] crypto: chacha - move existing library code into lib/crypto
+
+commit 5fb8ef25803ef33e2eb60b626435828b937bed75 upstream.
+
+Currently, our generic ChaCha implementation consists of a permute
+function in lib/chacha.c that operates on the 64-byte ChaCha state
+directly [and which is always included into the core kernel since it
+is used by the /dev/random driver], and the crypto API plumbing to
+expose it as a skcipher.
+
+In order to support in-kernel users that need the ChaCha streamcipher
+but have no need [or tolerance] for going through the abstractions of
+the crypto API, let's expose the streamcipher bits via a library API
+as well, in a way that permits the implementation to be superseded by
+an architecture specific one if provided.
+
+So move the streamcipher code into a separate module in lib/crypto,
+and expose the init() and crypt() routines to users of the library.

+Subject: [PATCH] crypto: x86/chacha - depend on generic chacha library instead
+ of crypto driver
+
+commit 28e8d89b1ce8d2e7badfb5f69971dd635acb8863 upstream.
+
+In preparation of extending the x86 ChaCha driver to also expose the ChaCha
+library interface, drop the dependency on the chacha_generic crypto driver
+as a non-SIMD fallback, and depend on the generic ChaCha library directly.
+This way, we only pull in the code we actually need, without registering
+a set of ChaCha skciphers that we will never use.
+
+Since turning the FPU on and off is cheap these days, simplify the SIMD
+routine by dropping the per-page yield, which makes for a cleaner switch
+to the library API as well. This also allows use to invoke the skcipher
+walk routines in non-atomic mode.

+ function
+
+commit 84e03fa39fbe95a5567d43bff458c6d3b3a23ad1 upstream.
+
+Wire the existing x86 SIMD ChaCha code into the new ChaCha library
+interface, so that users of the library interface will get the
+accelerated version when available.
+
+Given that calls into the library API will always go through the
+routines in this module if it is enabled, switch to static keys
+to select the optimal implementation available (which may be none
+at all, in which case we defer to the generic implementation for
+all invocations).

+Subject: [PATCH] crypto: arm64/chacha - depend on generic chacha library
+ instead of crypto driver
+
+commit c77da4867cbb7841177275dbb250f5c09679fae4 upstream.
+
+Depend on the generic ChaCha library routines instead of pulling in the
+generic ChaCha skcipher driver, which is more than we need, and makes
+managing the dependencies between the generic library, generic driver,
+accelerated library and driver more complicated.
+
+While at it, drop the logic to prefer the scalar code on short inputs.
+Turning the NEON on and off is cheap these days, and one major use case
+for ChaCha20 is ChaCha20-Poly1305, which is guaranteed to hit the scalar
+path upon every invocation (when doing the Poly1305 nonce generation)

+ function
+
+commit b3aad5bad26a01a4bd8c49a5c5f52aec665f3b7c upstream.
+
+Expose the accelerated NEON ChaCha routine directly as a symbol
+export so that users of the ChaCha library API can use it directly.
+
+Given that calls into the library API will always go through the
+routines in this module if it is enabled, switch to static keys
+to select the optimal implementation available (which may be none
+at all, in which case we defer to the generic implementation for
+all invocations).

++ *
++ * 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.

+Subject: [PATCH] crypto: arm/chacha - remove dependency on generic ChaCha
+ driver
+
+commit b36d8c09e710c71f6a9690b6586fea2d1c9e1e27 upstream.
+
+Instead of falling back to the generic ChaCha skcipher driver for
+non-SIMD cases, use a fast scalar implementation for ARM authored
+by Eric Biggers. This removes the module dependency on chacha-generic
+altogether, which also simplifies things when we expose the ChaCha
+library interface from this module.

+Subject: [PATCH] crypto: arm/chacha - expose ARM ChaCha routine as library
+ function
+
+commit a44a3430d71bad4ee56788a59fff099b291ea54c upstream.
+
+Expose the accelerated NEON ChaCha routine directly as a symbol
+export so that users of the ChaCha library API can use it directly.
+
+Given that calls into the library API will always go through the
+routines in this module if it is enabled, switch to static keys
+to select the optimal implementation available (which may be none
+at all, in which case we defer to the generic implementation for
+all invocations).

+From: Ard Biesheuvel <ardb@kernel.org>
+Date: Fri, 8 Nov 2019 13:22:17 +0100
+Subject: [PATCH] crypto: mips/chacha - wire up accelerated 32r2 code from Zinc
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 3a2f58f3ba4f6f44e33d1a48240d5eadb882cb59 upstream.
+
+This integrates the accelerated MIPS 32r2 implementation of ChaCha
+into both the API and library interfaces of the kernel crypto stack.
+
+The significance of this is that, in addition to becoming available
+as an accelerated library implementation, it can also be used by
+existing crypto API code such as Adiantum (for block encryption on
+ultra low performance cores) or IPsec using chacha20poly1305. These
+are use cases that have already opted into using the abstract crypto
+API. In order to support Adiantum, the core assembler routine has
+been adapted to take the round count as a function argument rather
+than hardcoding it to 20.

+Subject: [PATCH] crypto: chacha - unexport chacha_generic routines
+
+commit 22cf705360707ced15f9fe5423938f313c7df536 upstream.
+
+Now that all users of generic ChaCha code have moved to the core library,
+there is no longer a need for the generic ChaCha skcpiher driver to
+export parts of it implementation for reuse by other drivers. So drop
+the exports, and make the symbols static.

+Subject: [PATCH] crypto: poly1305 - move core routines into a separate library
+
+commit 48ea8c6ebc96bc0990e12ee1c43d0832c23576bb upstream.
+
+Move the core Poly1305 routines shared between the generic Poly1305
+shash driver and the Adiantum and NHPoly1305 drivers into a separate
+library so that using just this pieces does not pull in the crypto
+API pieces of the generic Poly1305 routine.
+
+In a subsequent patch, we will augment this generic library with
+init/update/final routines so that Poyl1305 algorithm can be used
+directly without the need for using the crypto API's shash abstraction.

+Subject: [PATCH] crypto: x86/poly1305 - unify Poly1305 state struct with
+ generic code
+
+commit ad8f5b88383ea685f2b8df2a12ee3e08089a1287 upstream.
+
+In preparation of exposing a Poly1305 library interface directly from
+the accelerated x86 driver, align the state descriptor of the x86 code
+with the one used by the generic driver. This is needed to make the
+library interface unified between all implementations.

+Subject: [PATCH] crypto: poly1305 - expose init/update/final library interface
+
+commit a1d93064094cc5e24d64e35cf093e7191d0c9344 upstream.
+
+Expose the existing generic Poly1305 code via a init/update/final
+library interface so that callers are not required to go through
+the crypto API's shash abstraction to access it. At the same time,
+make some preparations so that the library implementation can be
+superseded by an accelerated arch-specific version in the future.

+Subject: [PATCH] crypto: x86/poly1305 - depend on generic library not generic
+ shash
+
+commit 1b2c6a5120489d41c8ea3b8dacd0b4586289b158 upstream.
+
+Remove the dependency on the generic Poly1305 driver. Instead, depend
+on the generic library so that we only reuse code without pulling in
+the generic skcipher implementation as well.
+
+While at it, remove the logic that prefers the non-SIMD path for short
+inputs - this is no longer necessary after recent FPU handling changes
+on x86.
+
+Since this removes the last remaining user of the routines exported
+by the generic shash driver, unexport them and make them static.

+Subject: [PATCH] crypto: arm64/poly1305 - incorporate OpenSSL/CRYPTOGAMS NEON
+ implementation
+
+commit f569ca16475155013525686d0f73bc379c67e635 upstream.
+
+This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation
+for NEON authored by Andy Polyakov, and contributed by him to the OpenSSL
+project. The file 'poly1305-armv8.pl' is taken straight from this upstream
+GitHub repository [0] at commit ec55a08dc0244ce570c4fc7cade330c60798952f,
+and already contains all the changes required to build it as part of a
+Linux kernel module.

+Subject: [PATCH] crypto: arm/poly1305 - incorporate OpenSSL/CRYPTOGAMS NEON
+ implementation
+
+commit a6b803b3ddc793d6db0c16f12fc12d30d20fa9cc upstream.
+
+This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation
+for NEON authored by Andy Polyakov, and contributed by him to the OpenSSL
+project. The file 'poly1305-armv4.pl' is taken straight from this upstream
+GitHub repository [0] at commit ec55a08dc0244ce570c4fc7cade330c60798952f,
+and already contains all the changes required to build it as part of a
+Linux kernel module.

++ @
++ @ 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.

++ @ 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.

+Subject: [PATCH] crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS
+ optimized implementation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit a11d055e7a64ac34a5e99b6fe731299449cbcd58 upstream.
+
+This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for
+MIPS authored by Andy Polyakov, a prior 64-bit only version of which has been
+contributed by him to the OpenSSL project. The file 'poly1305-mips.pl' is taken
+straight from this upstream GitHub repository [0] at commit
+d22ade312a7af958ec955620b0d241cf42c37feb, and already contains all the changes
+required to build it as part of a Linux kernel module.

++# There is a number of MIPS ABI in use, O32 and N32/64 are most
++# widely used. Then there is a new contender: NUBI. It appears that if
++# one picks the latter, it's possible to arrange code in ABI neutral
++# manner. Therefore let's stick to NUBI register layout:
++#
++($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
++($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
++($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
++($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
++#
++# The return value is placed in $a0. Following coding rules facilitate
++# interoperability:
++#
++# - never ever touch $tp, "thread pointer", former $gp [o32 can be
++# excluded from the rule, because it's specified volatile];
++# - copy return value to $t0, former $v0 [or to $a0 if you're adapting
++# old code];
++# - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
++#
++# For reference here is register layout for N32/64 MIPS ABIs:
++#
++# ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
++# ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
++# ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
++# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
++# ($gp,$sp,$fp,$ra)=map("\$$_",(28..31));

+Subject: [PATCH] crypto: blake2s - generic C library implementation and
+ selftest
+
+commit 66d7fb94e4ffe5acc589e0b2b4710aecc1f07a28 upstream.
+
+The C implementation was originally based on Samuel Neves' public
+domain reference implementation but has since been heavily modified
+for the kernel. We're able to do compile-time optimizations by moving
+some scaffolding around the final function into the header file.

+[ardb: - move from lib/zinc to lib/crypto
+ - remove simd handling
+ - rewrote selftest for better coverage
+ - use fixed digest length for blake2s_hmac() and rename to
+ blake2s256_hmac() ]

+Subject: [PATCH] crypto: testmgr - add test cases for Blake2s
+
+commit 17e1df67023a5c9ccaeb5de8bf5b88f63127ecf7 upstream.
+
+As suggested by Eric for the Blake2b implementation contributed by
+David, introduce a set of test vectors for Blake2s covering different
+digest and key sizes.

+
+commit ed0356eda153f6a95649e11feb7b07083caf9e20 upstream.
+
+These implementations from Samuel Neves support AVX and AVX-512VL.
+Originally this used AVX-512F, but Skylake thermal throttling made
+AVX-512VL more attractive and possible to do with negligable difference.

+Subject: [PATCH] crypto: curve25519 - generic C library implementations
+
+commit 0ed42a6f431e930b2e8fae21955406e09fe75d70 upstream.
+
+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
+
+Information: https://cr.yp.to/ecdh.html

+Subject: [PATCH] crypto: lib/curve25519 - work around Clang stack spilling
+ issue
+
+commit 660bb8e1f833ea63185fe80fde847e3e42f18e3b upstream.
+
+Arnd reports that the 32-bit generic library code for Curve25119 ends
+up using an excessive amount of stack space when built with Clang:
+
+ lib/crypto/curve25519-fiat32.c:756:6: error: stack frame size
+ of 1384 bytes in function 'curve25519_generic'
+ [-Werror,-Wframe-larger-than=]
+
+Let's give some hints to the compiler regarding which routines should
+not be inlined, to prevent it from running out of registers and spilling
+to the stack. The resulting code performs identically under both GCC
+and Clang, and makes the warning go away.

+Subject: [PATCH] crypto: curve25519 - x86_64 library and KPP implementations
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit bb611bdfd6be34d9f822c73305fcc83720499d38 upstream.
+
+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.

+Subject: [PATCH] crypto: arm/curve25519 - import Bernstein and Schwabe's
+ Curve25519 ARM implementation
+
+commit f0fb006b604f98e2309a30f34ef455ac734f7c1c upstream.
+
+This comes from Dan Bernstein and Peter Schwabe's public domain NEON
+code, and is included here in raw form so that subsequent commits that
+fix these up for the kernel can see how it has changed. This code does
+have some entirely cosmetic formatting differences, adding indentation
+and so forth, so that when we actually port it for use in the kernel in
+the subsequent commit, it's obvious what's changed in the process.
+
+This code originates from SUPERCOP 20180818, available at
+<https://bench.cr.yp.to/supercop.html>.

+Subject: [PATCH] crypto: arm/curve25519 - wire up NEON implementation
+
+commit d8f1308a025fc7e00414194ed742d5f05a21e13c upstream.
+
+This ports the SUPERCOP implementation for usage in kernel space. In
+addition to the usual header, macro, and style changes required for
+kernel space, it makes a few small changes to the code:
+
+ - The stack alignment is relaxed to 16 bytes.
+ - Superfluous mov statements have been removed.
+ - ldr for constants has been replaced with movw.
+ - ldreq has been replaced with moveq.
+ - The str epilogue has been made more idiomatic.
+ - SIMD registers are not pushed and popped at the beginning and end.
+ - The prologue and epilogue have been made idiomatic.
+ - A hole has been removed from the stack, saving 32 bytes.
+ - We write-back the base register whenever possible for vld1.8.
+ - Some multiplications have been reordered for better A7 performance.
+
+There are more opportunities for cleanup, since this code is from qhasm,
+which doesn't always do the most opportune thing. But even prior to
+extensive hand optimizations, this code delivers significant performance
+improvements (given in get_cycles() per call):

+Subject: [PATCH] crypto: chacha20poly1305 - import construction and selftest
+ from Zinc
+
+commit ed20078b7e3331e82828be357147af6a3282e4ce upstream.
+
+This incorporates the chacha20poly1305 from the Zinc library, retaining
+the library interface, but replacing the implementation with calls into
+the code that already existed in the kernel's crypto API.
+
+Note that this library API does not implement RFC7539 fully, given that
+it is limited to 64-bit nonces. (The 96-bit nonce version that was part
+of the selftest only has been removed, along with the 96-bit nonce test
+vectors that only tested the selftest but not the actual library itself)

+Subject: [PATCH] crypto: lib/chacha20poly1305 - reimplement crypt_from_sg()
+ routine
+
+commit d95312a3ccc0cd544d374be2fc45aeaa803e5fd9 upstream.
+
+Reimplement the library routines to perform chacha20poly1305 en/decryption
+on scatterlists, without [ab]using the [deprecated] blkcipher interface,
+which is rather heavyweight and does things we don't really need.
+
+Instead, we use the sg_miter API in a novel and clever way, to iterate
+over the scatterlist in-place (i.e., source == destination, which is the
+only way this library is expected to be used). That way, we don't have to
+iterate over two scatterlists in parallel.
+
+Another optimization is that, instead of relying on the blkcipher walker
+to present the input in suitable chunks, we recognize that ChaCha is a
+streamcipher, and so we can simply deal with partial blocks by keeping a
+block of cipherstream on the stack and use crypto_xor() to mix it with
+the in/output.
+
+Finally, we omit the scatterwalk_and_copy() call if the last element of
+the scatterlist covers the MAC as well (which is the common case),
+avoiding the need to walk the scatterlist and kmap() the page twice.

+
+commit 413808b71e6204b0cc1eeaa77960f7c3cd381d33 upstream.
+
+Use chacha20_crypt() instead of chacha_crypt(), since it's not really
+appropriate for users of the ChaCha library API to be passing the number
+of rounds as an argument.

+Subject: [PATCH] crypto: arch - conditionalize crypto api in arch glue for lib
+ code
+
+commit 8394bfec51e0e565556101bcc4e2fe7551104cd8 upstream.
+
+For glue code that's used by Zinc, the actual Crypto API functions might
+not necessarily exist, and don't need to exist either. Before this
+patch, there are valid build configurations that lead to a unbuildable
+kernel. This fixes it to conditionalize those symbols on the existence
+of the proper config entry.

+ function
+
+commit 84faa307249b341f6ad8de3e1869d77a65e26669 upstream.
+
+Somehow this was forgotten when Zinc was being split into oddly shaped
+pieces, resulting in linker errors. The x86_64 glue has a specific key
+generation implementation, but the Arm one does not. However, it can
+still receive the NEON speedups by calling the ordinary DH function
+using the base point.

+commit aa127963f1cab2b93c74c9b128a84610203fb674 upstream.
+
+Somehow these were dropped when Zinc was being integrated, which is
+problematic, because testing the library interface for Curve25519 is
+important.. This commit simply adds them back and wires them in in the
+same way that the blake2s selftests are wired in.

+Subject: [PATCH] crypto: poly1305 - add new 32 and 64-bit generic versions
+
+commit 1c08a104360f3e18f4ee6346c21cc3923efb952e upstream.
+
+These two C implementations from Zinc -- 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. The
+precomputation in the 32-bit version and the use of 64x64 multiplies in
+the 64-bit version make these perform better than the code it replaces.
+Moon's code is also very widespread and has received many eyeballs of
+scrutiny.
+
+There's a bit of interference between the x86 implementation, which
+relies on internal details of the old scalar implementation. In the next
+commit, the x86 implementation will be replaced with a faster one that
+doesn't rely on this, so none of this matters much. But for now, to keep
+this passing the tests, we inline the bits of the old implementation
+that the x86 implementation relied on. Also, since we now support a
+slightly larger key space, via the union, some offsets had to be fixed
+up.
+
+Nonce calculation was folded in with the emit function, to take
+advantage of 64x64 arithmetic. However, Adiantum appeared to rely on no
+nonce handling in emit, so this path was conditionalized. We also
+introduced a new struct, poly1305_core_key, to represent the precise
+amount of space that particular implementation uses.
+
+Testing with kbench9000, depending on the CPU, the update function for
+the 32x32 version has been improved by 4%-7%, and for the 64x64 by
+19%-30%. The 32x32 gains are small, but I think there's great value in
+having a parallel implementation to the 64x64 one so that the two can be
+compared side-by-side as nice stand-alone units.

+Subject: [PATCH] crypto: x86/poly1305 - import unmodified cryptogams
+ implementation
+
+commit 0896ca2a0cb6127e8a129f1f2a680d49b6b0f65c upstream.
+
+These x86_64 vectorized implementations come from Andy Polyakov's
+CRYPTOGAMS 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.

++#
++# Convert AVX512F+VL+BW code path to pure AVX512F, so that it can be
++# executed even on Knights Landing. Trigger for modification was
++# observation that AVX512 code paths can negatively affect overall
++# Skylake-X system performance. Since we are likely to suppress
++# AVX512F capability flag [at least on Skylake-X], conversion serves
++# as kind of "investment protection". Note that next *lake processor,
++# Cannolake, has AVX512IFMA code path to execute...
++#
++# Numbers are cycles per processed byte with poly1305_blocks alone,
++# measured with rdtsc at fixed clock frequency.

++# One can argue that base 2^52 would be more natural. Well, even though
++# some operations would be more natural, one has to recognize couple of
++# things. Base 2^52 doesn't provide advantage over base 2^44 if you look
++# at amount of multiply-n-accumulate operations. Secondly, it makes it
++# impossible to pre-compute multiples of 5 [referred to as s[]/sN in
++# reference implementations], which means that more such operations
++# would have to be performed in inner loop, which in turn makes critical
++# path longer. In other words, even though base 2^44 reduction might
++# look less elegant, overall critical path is actually shorter...

+Subject: [PATCH] crypto: x86/poly1305 - wire up faster implementations for
+ kernel
+
+commit d7d7b853566254648df59f7ea27ea05952a6cfa8 upstream.
+
+These x86_64 vectorized implementations support AVX, AVX-2, and AVX512F.
+The AVX-512F implementation is disabled on Skylake, due to throttling,
+but it is quite fast on >= Cannonlake.
+
+On the left is cycle counts on a Core i7 6700HQ using the AVX-2
+codepath, comparing this implementation ("new") to the implementation in
+the current crypto api ("old"). On the right are benchmarks on a Xeon
+Gold 5120 using the AVX-512 codepath. The new implementation is faster
+on all benchmarks.

+
+This commit wires in the prior implementation from Andy, and makes the
+following changes to be suitable for kernel land.
+
+ - Some cosmetic and structural changes, like renaming labels to
+ .Lname, constants, and other Linux conventions, as well as making
+ the code easy for us to maintain moving forward.
+
+ - CPU feature checking is done in C by the glue code.
+
+ - We avoid jumping into the middle of functions, to appease objtool,
+ and instead parameterize shared code.
+
+ - We maintain frame pointers so that stack traces make sense.
+
+ - We remove the dependency on the perl xlate code, which transforms
+ the output into things that assemblers we don't care about use.
+
+Importantly, none of our changes affect the arithmetic or core code, but
+just involve the differing environment of kernel space.

+Subject: [PATCH] crypto: {arm,arm64,mips}/poly1305 - remove redundant
+ non-reduction from emit
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 31899908a0d248b030b4464425b86c717e0007d4 upstream.
+
+This appears to be some kind of copy and paste error, and is actually
+dead code.
+
+Pre: f = 0 ⇒ (f >> 32) = 0
+ f = (f >> 32) + le32_to_cpu(digest[0]);
+Post: 0 ≤ f < 2³²
+ put_unaligned_le32(f, dst);
+
+Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
+ f = (f >> 32) + le32_to_cpu(digest[1]);
+Post: 0 ≤ f < 2³²
+ put_unaligned_le32(f, dst + 4);
+
+Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
+ f = (f >> 32) + le32_to_cpu(digest[2]);
+Post: 0 ≤ f < 2³²
+ put_unaligned_le32(f, dst + 8);
+
+Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
+ f = (f >> 32) + le32_to_cpu(digest[3]);
+Post: 0 ≤ f < 2³²
+ put_unaligned_le32(f, dst + 12);
+
+Therefore this sequence is redundant. And Andy's code appears to handle
+misalignment acceptably.

+Subject: [PATCH] crypto: curve25519 - Fix selftest build error
+
+commit a8bdf2c42ee4d1ee42af1f3601f85de94e70a421 upstream.
+
+If CRYPTO_CURVE25519 is y, CRYPTO_LIB_CURVE25519_GENERIC will be
+y, but CRYPTO_LIB_CURVE25519 may be set to m, this causes build
+errors:
+
+lib/crypto/curve25519-selftest.o: In function `curve25519':
+curve25519-selftest.c:(.text.unlikely+0xc): undefined reference to `curve25519_arch'
+lib/crypto/curve25519-selftest.o: In function `curve25519_selftest':
+curve25519-selftest.c:(.init.text+0x17e): undefined reference to `curve25519_base_arch'
+
+This is because the curve25519 self-test code is being controlled
+by the GENERIC option rather than the overall CURVE25519 option,
+as is the case with blake2s. To recap, the GENERIC and ARCH options
+for CURVE25519 are internal only and selected by users such as
+the Crypto API, or the externally visible CURVE25519 option which
+in turn is selected by wireguard. The self-test is specific to the
+the external CURVE25519 option and should not be enabled by the
+Crypto API.
+
+This patch fixes this by splitting the GENERIC module from the
+CURVE25519 module with the latter now containing just the self-test.

+Subject: [PATCH] crypto: chacha20poly1305 - add back missing test vectors and
+ test chunking
+
+commit 72c7943792c9e7788ddd182337bcf8f650cf56f5 upstream.
+
+When this was originally ported, the 12-byte nonce vectors were left out
+to keep things simple. I agree that we don't need nor want a library
+interface for 12-byte nonces. But these test vectors were specially
+crafted to look at issues in the underlying primitives and related
+interactions. Therefore, we actually want to keep around all of the
+test vectors, and simply have a helper function to test them with.
+
+Secondly, the sglist-based chunking code in the library interface is
+rather complicated, so this adds a developer-only test for ensuring that
+all the book keeping is correct, across a wide array of possibilities.

+
+commit f9e7fe32a792726186301423ff63a465d63386e1 upstream.
+
+The emit code does optional base conversion itself in assembly, so we
+don't need to do that here. Also, neither one of these functions uses
+simd instructions, so checking for that doesn't make sense either.

+Subject: [PATCH] crypto: arm/chacha - fix build failured when kernel mode NEON
+ is disabled
+
+commit 0bc81767c5bd9d005fae1099fb39eb3688370cb1 upstream.
+
+When the ARM accelerated ChaCha driver is built as part of a configuration
+that has kernel mode NEON disabled, we expect the compiler to propagate
+the build time constant expression IS_ENABLED(CONFIG_KERNEL_MODE_NEON) in
+a way that eliminates all the cross-object references to the actual NEON
+routines, which allows the chacha-neon-core.o object to be omitted from
+the build entirely.
+
+Unfortunately, this fails to work as expected in some cases, and we may
+end up with a build error such as
+
+ chacha-glue.c:(.text+0xc0): undefined reference to `chacha_4block_xor_neon'
+
+caused by the fact that chacha_doneon() has not been eliminated from the
+object code, even though it will never be called in practice.
+
+Let's fix this by adding some IS_ENABLED(CONFIG_KERNEL_MODE_NEON) tests
+that are not strictly needed from a logical point of view, but should
+help the compiler infer that the NEON code paths are unreachable in
+those cases.

+Subject: [PATCH] crypto: chacha20poly1305 - prevent integer overflow on large
+ input
+
+commit c9cc0517bba9f0213f1e55172feceb99e5512daf upstream.
+
+This code assigns src_len (size_t) to sl (int), which causes problems
+when src_len is very large. Probably nobody in the kernel should be
+passing this much data to chacha20poly1305 all in one go anyway, so I
+don't think we need to change the algorithm or introduce larger types
+or anything. But we should at least error out early in this case and
+print a warning so that we get reports if this does happen and can look
+into why anybody is possibly passing it that much data or if they're
+accidently passing -1 or similar.

+Subject: [PATCH] crypto: x86/curve25519 - support assemblers with no adx
+ support
+
+commit 1579f1bc3b753d17a44de3457d5c6f4a5b14c752 upstream.
+
+Some older version of GAS do not support the ADX instructions, similarly
+to how they also don't support AVX and such. This commit adds the same
+build-time detection mechanisms we use for AVX and others for ADX, and
+then makes sure that the curve25519 library dispatcher calls the right
+functions.

+Subject: [PATCH] crypto: arm64/chacha - correctly walk through blocks
+
+commit c8cfcb78c65877313cda7bcbace624d3dbd1f3b3 upstream.
+
+Prior, passing in chunks of 2, 3, or 4, followed by any additional
+chunks would result in the chacha state counter getting out of sync,
+resulting in incorrect encryption/decryption, which is a pretty nasty
+crypto vuln: "why do images look weird on webpages?" WireGuard users
+never experienced this prior, because we have always, out of tree, used
+a different crypto library, until the recent Frankenzinc addition. This
+commit fixes the issue by advancing the pointers and state counter by
+the actual size processed. It also fixes up a bug in the (optional,
+costly) stride test that prevented it from running on arm64.
+
+Fixes: b3aad5bad26a ("crypto: arm64/chacha - expose arm64 ChaCha routine as library function")

+Subject: [PATCH] crypto: x86/curve25519 - replace with formally verified
+ implementation
+
+commit 07b586fe06625b0b610dc3d3a969c51913d143d4 upstream.
+
+This comes from INRIA's HACL*/Vale. It implements the same algorithm and
+implementation strategy as the code it replaces, only this code has been
+formally verified, sans the base point multiplication, which uses code
+similar to prior, only it uses the formally verified field arithmetic
+alongside reproducable ladder generation steps. This doesn't have a
+pure-bmi2 version, which means haswell no longer benefits, but the
+increased (doubled) code complexity is not worth it for a single
+generation of chips that's already old.
+
+Performance-wise, this is around 1% slower on older microarchitectures,
+and slightly faster on newer microarchitectures, mainly 10nm ones or
+backports of 10nm to 14nm. This implementation is "everest" below:
+
+Xeon E5-2680 v4 (Broadwell)
+
+ armfazh: 133340 cycles per call
+ everest: 133436 cycles per call
+
+Xeon Gold 5120 (Sky Lake Server)
+
+ armfazh: 112636 cycles per call
+ everest: 113906 cycles per call
+
+Core i5-6300U (Sky Lake Client)
+
+ armfazh: 116810 cycles per call
+ everest: 117916 cycles per call
+
+Core i7-7600U (Kaby Lake)
+
+ armfazh: 119523 cycles per call
+ everest: 119040 cycles per call
+
+Core i7-8750H (Coffee Lake)
+
+ armfazh: 113914 cycles per call
+ everest: 113650 cycles per call
+
+Core i9-9880H (Coffee Lake Refresh)
+
+ armfazh: 112616 cycles per call
+ everest: 114082 cycles per call
+
+Core i3-8121U (Cannon Lake)
+
+ armfazh: 113202 cycles per call
+ everest: 111382 cycles per call
+
+Core i7-8265U (Whiskey Lake)
+
+ armfazh: 127307 cycles per call
+ everest: 127697 cycles per call
+
+Core i7-8550U (Kaby Lake Refresh)
+
+ armfazh: 127522 cycles per call
+ everest: 127083 cycles per call
+
+Xeon Platinum 8275CL (Cascade Lake)
+
+ armfazh: 114380 cycles per call
+ everest: 114656 cycles per call
+
+Achieving these kind of results with formally verified code is quite
+remarkable, especialy considering that performance is favorable for
+newer chips.

+Date: Sun, 1 Mar 2020 16:06:56 +0800
+Subject: [PATCH] crypto: x86/curve25519 - leave r12 as spare register
+
+commit dc7fc3a53ae158263196b1892b672aedf67796c5 upstream.
+
+This updates to the newer register selection proved by HACL*, which
+leads to a more compact instruction encoding, and saves around 100
+cycles.

+Subject: [PATCH] crypto: arch/lib - limit simd usage to 4k chunks
+
+commit 706024a52c614b478b63f7728d202532ce6591a9 upstream.
+
+The initial Zinc patchset, after some mailing list discussion, contained
+code to ensure that kernel_fpu_enable would not be kept on for more than
+a 4k chunk, since it disables preemption. The choice of 4k isn't totally
+scientific, but it's not a bad guess either, and it's what's used in
+both the x86 poly1305, blake2s, and nhpoly1305 code already (in the form
+of PAGE_SIZE, which this commit corrects to be explicitly 4k for the
+former two).
+
+Ard did some back of the envelope calculations and found that
+at 5 cycles/byte (overestimate) on a 1ghz processor (pretty slow), 4k
+means we have a maximum preemption disabling of 20us, which Sebastian
+confirmed was probably a good limit.
+
+Unfortunately the chunking appears to have been left out of the final
+patchset that added the glue code. So, this commit adds it back in.

+Subject: [PATCH] crypto: x86/chacha-sse3 - use unaligned loads for state array
+
+commit e79a31715193686e92dadb4caedfbb1f5de3659c upstream.
+
+Due to the fact that the x86 port does not support allocating objects
+on the stack with an alignment that exceeds 8 bytes, we have a rather
+ugly hack in the x86 code for ChaCha to ensure that the state array is
+aligned to 16 bytes, allowing the SSE3 implementation of the algorithm
+to use aligned loads.
+
+Given that the performance benefit of using of aligned loads appears to
+be limited (~0.25% for 1k blocks using tcrypt on a Corei7-8650U), and
+the fact that this hack has leaked into generic ChaCha code, let's just
+remove it.

+Subject: [PATCH] crypto: x86/curve25519 - Remove unused carry variables
+
+commit 054a5540fb8f7268e2c79e9deab4242db15c8cba upstream.
+
+The carry variables are assigned but never used, which upsets
+the compiler. This patch removes them.

+Subject: [PATCH] crypto: curve25519-x86_64 - Use XORL r32,32
+
+commit db719539fd3889836900bf912755aa30a5985e9a upstream.
+
+x86_64 zero extends 32bit operations, so for 64bit operands,
+XORL r32,r32 is functionally equal to XORL r64,r64, but avoids
+a REX prefix byte when legacy registers are used.

+
+commit 7dfd1e01b3dfc13431b1b25720cf2692a7e111ef upstream.
+
+x86_64 zero extends 32bit operations, so for 64bit operands,
+XORL r32,r32 is functionally equal to XORQ r64,r64, but avoids
+a REX prefix byte when legacy registers are used.

+Subject: [PATCH] crypto: arm/chacha-neon - optimize for non-block size
+ multiples
+
+commit 86cd97ec4b943af35562a74688bc4e909b32c3d1 upstream.
+
+The current NEON based ChaCha implementation for ARM is optimized for
+multiples of 4x the ChaCha block size (64 bytes). This makes sense for
+block encryption, but given that ChaCha is also often used in the
+context of networking, it makes sense to consider arbitrary length
+inputs as well.
+
+For example, WireGuard typically uses 1420 byte packets, and performing
+ChaCha encryption involves 5 invocations of chacha_4block_xor_neon()
+and 3 invocations of chacha_block_xor_neon(), where the last one also
+involves a memcpy() using a buffer on the stack to process the final
+chunk of 1420 % 64 == 12 bytes.
+
+Let's optimize for this case as well, by letting chacha_4block_xor_neon()
+deal with any input size between 64 and 256 bytes, using NEON permutation
+instructions and overlapping loads and stores. This way, the 140 byte
+tail of a 1420 byte input buffer can simply be processed in one go.
+
+This results in the following performance improvements for 1420 byte
+blocks, without significant impact on power-of-2 input sizes. (Note
+that Raspberry Pi is widely used in combination with a 32-bit kernel,
+even though the core is 64-bit capable)

+Subject: [PATCH] crypto: arm64/chacha - simplify tail block handling
+
+commit c4fc6328d6c67690a7e6e03f43a5a976a13120ef upstream.
+
+Based on lessons learnt from optimizing the 32-bit version of this driver,
+we can simplify the arm64 version considerably, by reordering the final
+two stores when the last block is not a multiple of 64 bytes. This removes
+the need to use permutation instructions to calculate the elements that are
+clobbered by the final overlapping store, given that the store of the
+penultimate block now follows it, and that one carries the correct values
+for those elements already.
+
+While at it, simplify the overlapping loads as well, by calculating the
+address of the final overlapping load upfront, and switching to this
+address for every load that would otherwise extend past the end of the
+source buffer.
+
+There is no impact on performance, but the resulting code is substantially
+smaller and easier to follow.

+
+With no mod_exit function, users are unable to unload the module after

+prohibited for this one, so this commit simply adds an empty exit
+function.

+Subject: [PATCH] crypto: arm/chacha-neon - add missing counter increment
+
+commit fd16931a2f518a32753920ff20895e5cf04c8ff1 upstream.
+
+Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block
+size multiples") refactored the chacha block handling in the glue code in
+a way that may result in the counter increment to be omitted when calling
+chacha_block_xor_neon() to process a full block. This violates the skcipher
+API, which requires that the output IV is suitable for handling more input
+as long as the preceding input has been presented in round multiples of the
+block size. Also, the same code is exposed via the chacha library interface
+whose callers may actually rely on this increment to occur even for final
+blocks that are smaller than the chacha block size.
+
+So increment the counter after calling chacha_block_xor_neon().
+

+Subject: [PATCH] net: WireGuard secure network tunnel
+
+commit e7096c131e5161fa3b8e52a650d7719d2857adfd upstream.
+
+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 tools
+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], peerlookup.[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 various 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: NLA_EXACT_LEN, len WG_KEY_LEN
++ * WGDEVICE_A_PUBLIC_KEY: NLA_EXACT_LEN, 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: NLA_EXACT_LEN, len WG_KEY_LEN
++ * WGPEER_A_PRESHARED_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
++ * WGPEER_A_ENDPOINT: NLA_MIN_LEN(struct sockaddr), struct sockaddr_in or struct sockaddr_in6
++ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
++ * WGPEER_A_LAST_HANDSHAKE_TIME: NLA_EXACT_LEN, struct __kernel_timespec
++ * WGPEER_A_RX_BYTES: NLA_U64
++ * WGPEER_A_TX_BYTES: NLA_U64
++ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
++ * 0: NLA_NESTED
++ * WGALLOWEDIP_A_FAMILY: NLA_U16
++ * WGALLOWEDIP_A_IPADDR: NLA_MIN_LEN(struct in_addr), struct in_addr or struct in6_addr
++ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
++ * 0: NLA_NESTED
++ * ...
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ * WGPEER_A_PROTOCOL_VERSION: NLA_U32
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ *
++ * 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 not exist at the end of the
++ * operation, 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 and/or WGPEER_F_UPDATE_ONLY if the
++ * peer should only be set if it already exists.
++ * 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
++ * 0: NLA_NESTED
++ * ...
++ * 0: 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.
++ * 0: 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.

+Subject: [PATCH] wireguard: selftests: import harness makefile for test suite
+
+commit 65d88d04114bca7d85faebd5fed61069cb2b632c upstream.
+
+WireGuard has been using this on build.wireguard.com for the last
+several years with considerable success. It allows for very quick and
+iterative development cycles, and supports several platforms.
+
+To run the test suite on your current platform in QEMU:
+
+ $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
+
+To run it with KASAN and such turned on:
+
+ $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
+
+To run it emulated for another platform in QEMU:
+
+ $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc)
+
+At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k,
+mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64.
+
+The system supports incremental rebuilding, so it should be very fast to
+change a single file and then test it out and have immediate feedback.
+
+This requires for the right toolchain and qemu to be installed prior.
+I've had success with those from musl.cc.
+
+This is tailored for WireGuard at the moment, though later projects
+might generalize it for other network testing.

+
+commit d7c68a38bb4f9b7c1a2e4a772872c752ee5c44a6 upstream.
+
+This fixes the crypto selection submenu depenencies. Otherwise, we'd
+wind up issuing warnings in which certain dependencies we also select
+couldn't be satisfied. This condition was triggered by the addition of
+the test suite autobuilder in the previous commit.

+Subject: [PATCH] wireguard: selftests: remove ancient kernel compatibility
+ code
+
+commit 9a69a4c8802adf642bc4a13d471b5a86b44ed434 upstream.
+
+Quite a bit of the test suite was designed to work with ancient kernels.
+Thankfully we no longer have to deal with this. This commit updates
+things that we can finally update and removes things that we can finally
+remove, to avoid the build-up of the last several years as a result of
+having to support ancient kernels. We can finally rely on suppress_
+prefixlength being available. On the build side of things, the no-PIE
+hack is no longer required, and we can bump some of the tools, repair
+our m68k and i686-kvm support, and get better coverage of the static
+branches used in the crypto lib and in udp_tunnel.

+Subject: [PATCH] wireguard: queueing: do not account for pfmemalloc when
+ clearing skb header
+
+commit 04d2ea92a18417619182cbb79063f154892b0150 upstream.
+
+Before 8b7008620b84 ("net: Don't copy pfmemalloc flag in __copy_skb_
+header()"), the pfmemalloc flag used to be between headers_start and
+headers_end, which is a region we clear when preparing the packet for
+encryption/decryption. This is a parameter we certainly want to
+preserve, which is why 8b7008620b84 moved it out of there. The code here
+was written in a world before 8b7008620b84, though, where we had to
+manually account for it. This commit brings things up to speed.

+Subject: [PATCH] wireguard: socket: mark skbs as not on list when receiving
+ via gro
+
+commit 736775d06bac60d7a353e405398b48b2bd8b1e54 upstream.
+
+Certain drivers will pass gro skbs to udp, at which point the udp driver
+simply iterates through them and passes them off to encap_rcv, which is
+where we pick up. At the moment, we're not attempting to coalesce these
+into bundles, but we also don't want to wind up having cascaded lists of
+skbs treated separately. The right behavior here, then, is to just mark
+each incoming one as not on a list. This can be seen in practice, for
+example, with Qualcomm's rmnet_perf driver.

+Subject: [PATCH] wireguard: noise: reject peers with low order public keys
+
+commit ec31c2676a10e064878927b243fada8c2fb0c03c upstream.
+
+Our static-static calculation returns a failure if the public key is of
+low order. We check for this when peers are added, and don't allow them
+to be added if they're low order, except in the case where we haven't
+yet been given a private key. In that case, we would defer the removal
+of the peer until we're given a private key, since at that point we're
+doing new static-static calculations which incur failures we can act on.
+This meant, however, that we wound up removing peers rather late in the
+configuration flow.
+
+Syzkaller points out that peer_remove calls flush_workqueue, which in
+turn might then wait for sending a handshake initiation to complete.
+Since handshake initiation needs the static identity lock, holding the
+static identity lock while calling peer_remove can result in a rare
+deadlock. We have precisely this case in this situation of late-stage
+peer removal based on an invalid public key. We can't drop the lock when
+removing, because then incoming handshakes might interact with a bogus
+static-static calculation.
+
+While the band-aid patch for this would involve breaking up the peer
+removal into two steps like wg_peer_remove_all does, in order to solve
+the locking issue, there's actually a much more elegant way of fixing
+this:
+
+If the static-static calculation succeeds with one private key, it
+*must* succeed with all others, because all 32-byte strings map to valid
+private keys, thanks to clamping. That means we can get rid of this
+silly dance and locking headaches of removing peers late in the
+configuration flow, and instead just reject them early on, regardless of
+whether the device has yet been assigned a private key. For the case
+where the device doesn't yet have a private key, we safely use zeros
+just for the purposes of checking for low order points by way of
+checking the output of the calculation.
+
+The following PoC will trigger the deadlock:
+
+ip link add wg0 type wireguard
+ip addr add 10.0.0.1/24 dev wg0
+ip link set wg0 up
+ping -f 10.0.0.2 &
+while true; do
+ wg set wg0 private-key /dev/null peer AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= allowed-ips 10.0.0.0/24 endpoint 10.0.0.3:1234
+ wg set wg0 private-key <(echo AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=)
+done

+Subject: [PATCH] wireguard: selftests: ensure non-addition of peers with
+ failed precomputation
+
+commit f9398acba6a4ae9cb98bfe4d56414d376eff8d57 upstream.
+
+Ensure that peers with low order points are ignored, both in the case
+where we already have a device private key and in the case where we do
+not. This adds points that naturally give a zero output.

+
+commit 88f404a9b1d75388225b1c67b6dd327cb2182777 upstream.
+
+Without this, we wind up proceeding too early sometimes when the
+previous process has just used the same listening port. So, we tie the
+listening socket query to the specific pid we're interested in.

+Subject: [PATCH] wireguard: device: use icmp_ndo_send helper
+
+commit a12d7f3cbdc72c7625881c8dc2660fc2c979fdf2 upstream.
+
+Because wireguard is calling icmp from network device context, it should
+use the ndo helper so that the rate limiting applies correctly. This
+commit adds a small test to the wireguard test suite to ensure that the
+new functions continue doing the right thing in the context of
+wireguard. It does this by setting up a condition that will definately
+evoke an icmp error message from the driver, but along a nat'd path.

+
+commit 2a8a4df36462aa85b0db87b7c5ea145ba67e34a8 upstream.
+
+This is a small optimization that prevents more expensive comparisons
+from happening when they are no longer necessary, by clearing the
+last_under_load variable whenever we wind up in a state where we were
+under load but we no longer are.

+Subject: [PATCH] wireguard: send: account for mtu=0 devices
+
+commit 175f1ca9a9ed8689d2028da1a7c624bb4fb4ff7e upstream.
+
+It turns out there's an easy way to get packets queued up while still
+having an MTU of zero, and that's via persistent keep alive. This commit
+makes sure that in whatever condition, we don't wind up dividing by
+zero. Note that an MTU of zero for a wireguard interface is something
+quasi-valid, so I don't think the correct fix is to limit it via
+min_mtu. This can be reproduced easily with:
+
+ip link add wg0 type wireguard
+ip link add wg1 type wireguard
+ip link set wg0 up mtu 0
+ip link set wg1 up
+wg set wg0 private-key <(wg genkey)
+wg set wg1 listen-port 1 private-key <(wg genkey) peer $(wg show wg0 public-key)
+wg set wg0 peer $(wg show wg1 public-key) persistent-keepalive 1 endpoint 127.0.0.1:1
+
+However, while min_mtu=0 seems fine, it makes sense to restrict the
+max_mtu. This commit also restricts the maximum MTU to the greatest
+number for which rounding up to the padding multiple won't overflow a
+signed integer. Packets this large were always rejected anyway
+eventually, due to checks deeper in, but it seems more sound not to even
+let the administrator configure something that won't work anyway.
+
+We use this opportunity to clean up this function a bit so that it's
+clear which paths we're expecting.

+
+commit 1fbc33b0a7feb6ca72bf7dc8a05d81485ee8ee2e upstream.
+
+synchronize_net() is a wrapper around synchronize_rcu(), so there's no
+point in having synchronize_net and synchronize_rcu back to back,
+despite the documentation comment suggesting maybe it's somewhat useful,
+"Wait for packets currently being received to be done." This commit

+Subject: [PATCH] wireguard: queueing: account for skb->protocol==0
+
+commit a5588604af448664e796daf3c1d5a4523c60667b upstream.
+
+We carry out checks to the effect of:
+
+ if (skb->protocol != wg_examine_packet_protocol(skb))
+ goto err;
+
+By having wg_skb_examine_untrusted_ip_hdr return 0 on failure, this
+means that the check above still passes in the case where skb->protocol
+is zero, which is possible to hit with AF_PACKET:
+
+ struct sockaddr_pkt saddr = { .spkt_device = "wg0" };
+ unsigned char buffer[5] = { 0 };
+ sendto(socket(AF_PACKET, SOCK_PACKET, /* skb->protocol = */ 0),
+ buffer, sizeof(buffer), 0, (const struct sockaddr *)&saddr, sizeof(saddr));
+
+Additional checks mean that this isn't actually a problem in the code
+base, but I could imagine it becoming a problem later if the function is
+used more liberally.
+
+I would prefer to fix this by having wg_examine_packet_protocol return a
+32-bit ~0 value on failure, which will never match any value of
+skb->protocol, which would simply change the generated code from a mov
+to a movzx. However, sparse complains, and adding __force casts doesn't
+seem like a good idea, so instead we just add a simple helper function
+to check for the zero return value. Since wg_examine_packet_protocol
+itself gets inlined, this winds up not adding an additional branch to
+the generated code, since the 0 return value already happens in a
+mergable branch.

+ rather than config
+
+commit 11a7686aa99c7fe4b3f80f6dcccd54129817984d upstream.
+
+We precompute the static-static ECDH during configuration time, in order
+to save an expensive computation later when receiving network packets.
+However, not all ECDH computations yield a contributory result. Prior,
+we were just not letting those peers be added to the interface. However,
+this creates a strange inconsistency, since it was still possible to add
+other weird points, like a valid public key plus a low-order point, and,
+like points that result in zeros, a handshake would not complete. In
+order to make the behavior more uniform and less surprising, simply
+allow all peers to be added. Then, we'll error out later when doing the
+crypto if there's an issue. This also adds more separation between the
+crypto layer and the configuration layer.

+Subject: [PATCH] wireguard: receive: use tunnel helpers for decapsulating ECN
+ markings
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit eebabcb26ea1e3295704477c6cd4e772c96a9559 upstream.
+
+WireGuard currently only propagates ECN markings on tunnel decap according
+to the old RFC3168 specification. However, the spec has since been updated
+in RFC6040 to recommend slightly different decapsulation semantics. This
+was implemented in the kernel as a set of common helpers for ECN
+decapsulation, so let's just switch over WireGuard to using those, so it
+can benefit from this enhancement and any future tweaks. We do not drop
+packets with invalid ECN marking combinations, because WireGuard is
+frequently used to work around broken ISPs, which could be doing that.

+
+commit a0fd7cc87a018df1a17f9d3f0bd994c1f22c6b34 upstream.
+
+While at some point it might have made sense to be running these tests
+on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on
+64-bit powerpc in a long time, and more interesting things that we test
+don't really work when we deviate from the default (16k). So, we stop
+pushing our luck in this commit, and return to the default instead of
+the minimum.

+Subject: [PATCH] wireguard: socket: remove errant restriction on looping to
+ self
+
+commit b673e24aad36981f327a6570412ffa7754de8911 upstream.
+
+It's already possible to create two different interfaces and loop
+packets between them. This has always been possible with tunnels in the
+kernel, and isn't specific to wireguard. Therefore, the networking stack
+already needs to deal with that. At the very least, the packet winds up
+exceeding the MTU and is discarded at that point. So, since this is
+already something that happens, there's no need to forbid the not very
+exceptional case of routing a packet back to the same interface; this
+loop is no different than others, and we shouldn't special case it, but
+rather rely on generic handling of loops in general. This also makes it
+easier to do interesting things with wireguard such as onion routing.
+
+At the same time, we add a selftest for this, ensuring that both onion
+routing works and infinite routing loops do not crash the kernel. We
+also add a test case for wireguard interfaces nesting packets and
+sending traffic between each other, as well as the loop in this case
+too. We make sure to send some throughput-heavy traffic for this use
+case, to stress out any possible recursion issues with the locks around
+workqueues.

+ worker ringbuffers
+
+commit 4005f5c3c9d006157ba716594e0d70c88a235c5e upstream.
+
+Users with pathological hardware reported CPU stalls on CONFIG_
+PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning
+these workers would never terminate. That turned out not to be okay on
+systems without forced preemption, which Sultan observed. This commit
+adds a cond_resched() to the bottom of each loop iteration, so that
+these workers don't hog the core. Note that we don't need this on the
+napi poll worker, since that terminates after its budget is expended.

+Subject: [PATCH] wireguard: send/receive: use explicit unlikely branch instead
+ of implicit coalescing
+
+commit 243f2148937adc72bcaaa590d482d599c936efde upstream.
+
+It's very unlikely that send will become true. It's nearly always false
+between 0 and 120 seconds of a session, and in most cases becomes true
+only between 120 and 121 seconds before becoming false again. So,
+unlikely(send) is clearly the right option here.
+
+What happened before was that we had this complex boolean expression
+with multiple likely and unlikely clauses nested. Since this is
+evaluated left-to-right anyway, the whole thing got converted to
+unlikely. So, we can clean this up to better represent what's going on.
+
+The generated code is the same.

+Subject: [PATCH] wireguard: selftests: use newer iproute2 for gcc-10
+
+commit ee3c1aa3f34b7842c1557cfe5d8c3f7b8c692de8 upstream.
+
+gcc-10 switched to defaulting to -fno-common, which broke iproute2-5.4.
+This was fixed in iproute-5.6, so switch to that. Because we're after a
+stable testing surface, we generally don't like to bump these
+unnecessarily, but in this case, being able to actually build is a basic
+necessity.

+Subject: [PATCH] wireguard: noise: read preshared key while taking lock
+
+commit bc67d371256f5c47d824e2eec51e46c8d62d022e upstream.
+
+Prior we read the preshared key after dropping the handshake lock, which
+isn't an actual crypto issue if it races, but it's still not quite
+correct. So copy that part of the state into a temporary like we do with
+the rest of the handshake state variables. Then we can release the lock,
+operate on the temporary, and zero it out at the end of the function. In
+performance tests, the impact of this was entirely unnoticable, probably
+because those bytes are coming from the same cacheline as other things
+that are being copied out in the same manner.

+Subject: [PATCH] wireguard: queueing: preserve flow hash across packet
+ scrubbing
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit c78a0b4a78839d572d8a80f6a62221c0d7843135 upstream.
+
+It's important that we clear most header fields during encapsulation and
+decapsulation, because the packet is substantially changed, and we don't
+want any info leak or logic bug due to an accidental correlation. But,
+for encapsulation, it's wrong to clear skb->hash, since it's used by
+fq_codel and flow dissection in general. Without it, classification does
+not proceed as usual. This change might make it easier to estimate the
+number of innerflows by examining clustering of out of order packets,
+but this shouldn't open up anything that can't already be inferred
+otherwise (e.g. syn packet size inference), and fq_codel can be disabled
+anyway.
+
+Furthermore, it might be the case that the hash isn't used or queried at
+all until after wireguard transmits the encrypted UDP packet, which
+means skb->hash might still be zero at this point, and thus no hash
+taken over the inner packet data. In order to address this situation, we
+force a calculation of skb->hash before encrypting packet data.
+
+Of course this means that fq_codel might transmit packets slightly more
+out of order than usual. Toke did some testing on beefy machines with
+high quantities of parallel flows and found that increasing the
+reply-attack counter to 8192 takes care of the most pathological cases
+pretty well.

+Subject: [PATCH] wireguard: noise: separate receive counter from send counter
+
+commit a9e90d9931f3a474f04bab782ccd9d77904941e9 upstream.
+
+In "wireguard: queueing: preserve flow hash across packet scrubbing", we
+were required to slightly increase the size of the receive replay
+counter to something still fairly small, but an increase nonetheless.
+It turns out that we can recoup some of the additional memory overhead
+by splitting up the prior union type into two distinct types. Before, we
+used the same "noise_counter" union for both sending and receiving, with
+sending just using a simple atomic64_t, while receiving used the full
+replay counter checker. This meant that most of the memory being
+allocated for the sending counter was being wasted. Since the old
+"noise_counter" type increased in size in the prior commit, now is a
+good time to split up that union type into a distinct "noise_replay_
+counter" for receiving and a boring atomic64_t for sending, each using
+neither more nor less memory than required.
+
+Also, since sometimes the replay counter is accessed without
+necessitating additional accesses to the bitmap, we can reduce cache
+misses by hoisting the always-necessary lock above the bitmap in the
+struct layout. We also change a "noise_replay_counter" stack allocation
+to kmalloc in a -DDEBUG selftest so that KASAN doesn't trigger a stack
+frame warning.
+
+All and all, removing a bit of abstraction in this commit makes the code
+simpler and smaller, in addition to the motivating memory usage
+recuperation. For example, passing around raw "noise_symmetric_key"
+structs is something that really only makes sense within noise.c, in the
+one place where the sending and receiving keys can safely be thought of
+as the same type of object; subsequent to that, it's important that we
+uniformly access these through keypair->{sending,receiving}, where their
+distinct roles are always made explicit. So this patch allows us to draw
+that distinction clearly as well.

+Subject: [PATCH] wireguard: device: avoid circular netns references
+
+commit 900575aa33a3eaaef802b31de187a85c4a4b4bd0 upstream.
+
+Before, we took a reference to the creating netns if the new netns was
+different. This caused issues with circular references, with two
+wireguard interfaces swapping namespaces. The solution is to rather not
+take any extra references at all, but instead simply invalidate the
+creating netns pointer when that netns is deleted.
+
+In order to prevent this from happening again, this commit improves the
+rough object leak tracking by allowing it to account for created and
+destroyed interfaces, aside from just peers and keys. That then makes it
+possible to check for the object leak when having two interfaces take a
+reference to each others' namespaces.
+

+Subject: [PATCH] wireguard: receive: account for napi_gro_receive never
+ returning GRO_DROP
+
+commit df08126e3833e9dca19e2407db5f5860a7c194fb upstream.
+
+The napi_gro_receive function no longer returns GRO_DROP ever, making
+handling GRO_DROP dead code. This commit removes that dead code.
+Further, it's not even clear that device drivers have any business in
+taking action after passing off received packets; that's arguably out of
+their hands.

+
+commit 2606aff916854b61234bf85001be9777bab2d5f8 upstream.
+
+Some devices that take straight up layer 3 packets benefit from having a
+shared header_ops so that AF_PACKET sockets can inject packets that are
+recognized. This shared infrastructure will be used by other drivers
+that currently can't inject packets using AF_PACKET. It also exposes the
+parser function, as it is useful in standalone form too.

+Subject: [PATCH] wireguard: implement header_ops->parse_protocol for AF_PACKET
+
+commit 01a4967c71c004f8ecad4ab57021348636502fa9 upstream.
+
+WireGuard uses skb->protocol to determine packet type, and bails out if
+it's not set or set to something it's not expecting. For AF_PACKET
+injection, we need to support its call chain of:
+
+ packet_sendmsg -> packet_snd -> packet_parse_headers ->
+ dev_parse_header_protocol -> parse_protocol
+
+Without a valid parse_protocol, this returns zero, and wireguard then
+rejects the skb. So, this wires up the ip_tunnel handler for layer 3
+packets for that case.

+
+commit 1a574074ae7d1d745c16f7710655f38a53174c27 upstream.
+
+Now that wg_examine_packet_protocol has been added for general

+wg_examine_packet_protocol and simply use the new
+ip_tunnel_parse_protocol function directly.

+Subject: [PATCH] wireguard: noise: take lock when removing handshake entry
+ from table
+
+commit 9179ba31367bcf481c3c79b5f028c94faad9f30a upstream.
+
+Eric reported that syzkaller found a race of this variety:
+
+CPU 1 CPU 2
+-------------------------------------------|---------------------------------------
+wg_index_hashtable_replace(old, ...) |
+ if (hlist_unhashed(&old->index_hash)) |
+ | wg_index_hashtable_remove(old)
+ | hlist_del_init_rcu(&old->index_hash)
+ | old->index_hash.pprev = NULL
+ hlist_replace_rcu(&old->index_hash, ...) |
+ *old->index_hash.pprev |
+
+Syzbot wasn't actually able to reproduce this more than once or create a
+reproducer, because the race window between checking "hlist_unhashed" and
+calling "hlist_replace_rcu" is just so small. Adding an mdelay(5) or
+similar there helps make this demonstrable using this simple script:
+
+ #!/bin/bash
+ set -ex
+ trap 'kill $pid1; kill $pid2; ip link del wg0; ip link del wg1' EXIT
+ ip link add wg0 type wireguard
+ ip link add wg1 type wireguard
+ wg set wg0 private-key <(wg genkey) listen-port 9999
+ wg set wg1 private-key <(wg genkey) peer $(wg show wg0 public-key) endpoint 127.0.0.1:9999 persistent-keepalive 1
+ wg set wg0 peer $(wg show wg1 public-key)
+ ip link set wg0 up
+ yes link set wg1 up | ip -force -batch - &
+ pid1=$!
+ yes link set wg1 down | ip -force -batch - &
+ pid2=$!
+ wait
+
+The fundumental underlying problem is that we permit calls to wg_index_
+hashtable_remove(handshake.entry) without requiring the caller to take
+the handshake mutex that is intended to protect members of handshake
+during mutations. This is consistently the case with calls to wg_index_
+hashtable_insert(handshake.entry) and wg_index_hashtable_replace(
+handshake.entry), but it's missing from a pertinent callsite of wg_
+index_hashtable_remove(handshake.entry). So, this patch makes sure that
+mutex is taken.
+
+The original code was a little bit funky though, in the form of:
+
+ remove(handshake.entry)
+ lock(), memzero(handshake.some_members), unlock()
+ remove(handshake.entry)
+
+The original intention of that double removal pattern outside the lock
+appears to be some attempt to prevent insertions that might happen while
+locks are dropped during expensive crypto operations, but actually, all
+callers of wg_index_hashtable_insert(handshake.entry) take the write
+lock and then explicitly check handshake.state, as they should, which
+the aforementioned memzero clears, which means an insertion should
+already be impossible. And regardless, the original intention was
+necessarily racy, since it wasn't guaranteed that something else would
+run after the unlock() instead of after the remove(). So, from a
+soundness perspective, it seems positive to remove what looks like a
+hack at best.
+
+The crash from both syzbot and from the script above is as follows:
+
+ general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN

+Subject: [PATCH] wireguard: peerlookup: take lock before checking hash in
+ replace operation
+
+commit 6147f7b1e90ff09bd52afc8b9206a7fcd133daf7 upstream.
+
+Eric's suggested fix for the previous commit's mentioned race condition
+was to simply take the table->lock in wg_index_hashtable_replace(). The
+table->lock of the hash table is supposed to protect the bucket heads,
+not the entires, but actually, since all the mutator functions are
+already taking it, it makes sense to take it too for the test to
+hlist_unhashed, as a defense in depth measure, so that it no longer
+races with deletions, regardless of what other locks are protecting
+individual entries. This is sensible from a performance perspective
+because, as Eric pointed out, the case of being unhashed is already the
+unlikely case, so this won't add common contention. And comparing
+instructions, this basically doesn't make much of a difference other
+than pushing and popping %r13, used by the new `bool ret`. More
+generally, I like the idea of locking consistency across table mutator
+functions, and this might let me rest slightly easier at night.

+Subject: [PATCH] wireguard: selftests: check that route_me_harder packets use
+ the right sk
+
+commit af8afcf1fdd5f365f70e2386c2d8c7a1abd853d7 upstream.
+
+If netfilter changes the packet mark, the packet is rerouted. The
+ip_route_me_harder family of functions fails to use the right sk, opting
+to instead use skb->sk, resulting in a routing loop when used with
+tunnels. With the next change fixing this issue in netfilter, test for
+the relevant condition inside our test suite, since wireguard was where
+the bug was discovered.

+
+commit 30ac4e2f54ec067b7b9ca0db27e75681581378d6 upstream.
+
+The definition of IS_ERR() already applies the unlikely() notation
+when checking the error status of the passed pointer. For this
+reason there is no need to have the same notation outside of
+IS_ERR() itself.
+
+Clean up code by removing redundant notation.

+Subject: [PATCH] wireguard: socket: remove bogus __be32 annotation
+
+commit 7f57bd8dc22de35ddd895294aa554003e4f19a72 upstream.
+
+The endpoint->src_if4 has nothing to do with fixed-endian numbers; remove
+the bogus annotation.
+
+This was introduced in
+https://git.zx2c4.com/wireguard-monolithic-historical/commit?id=14e7d0a499a676ec55176c0de2f9fcbd34074a82
+in the historical WireGuard repo because the old code used to
+zero-initialize multiple members as follows:
+
+ endpoint->src4.s_addr = endpoint->src_if4 = fl.saddr = 0;
+
+Because fl.saddr is fixed-endian and an assignment returns a value with the
+type of its left operand, this meant that sparse detected an assignment
+between values of different endianness.
+
+Since then, this assignment was already split up into separate statements;
+just the cast survived.

+
+In order to test ndo_start_xmit being called in parallel, explicitly add

+Subject: [PATCH] wireguard: queueing: get rid of per-peer ring buffers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 8b5553ace83cced775eefd0f3f18b5c6214ccf7a upstream.
+
+Having two ring buffers per-peer means that every peer results in two
+massive ring allocations. On an 8-core x86_64 machine, this commit
+reduces the per-peer allocation from 18,688 bytes to 1,856 bytes, which
+is an 90% reduction. Ninety percent! With some single-machine
+deployments approaching 500,000 peers, we're talking about a reduction
+from 7 gigs of memory down to 700 megs of memory.
+
+In order to get rid of these per-peer allocations, this commit switches
+to using a list-based queueing approach. Currently GSO fragments are
+chained together using the skb->next pointer (the skb_list_* singly
+linked list approach), so we form the per-peer queue around the unused
+skb->prev pointer (which sort of makes sense because the links are
+pointing backwards). Use of skb_queue_* is not possible here, because
+that is based on doubly linked lists and spinlocks. Multiple cores can
+write into the queue at any given time, because its writes occur in the
+start_xmit path or in the udp_recv path. But reads happen in a single
+workqueue item per-peer, amounting to a multi-producer, single-consumer
+paradigm.
+
+The MPSC queue is implemented locklessly and never blocks. However, it
+is not linearizable (though it is serializable), with a very tight and
+unlikely race on writes, which, when hit (some tiny fraction of the
+0.15% of partial adds on a fully loaded 16-core x86_64 system), causes
+the queue reader to terminate early. However, because every packet sent
+queues up the same workqueue item after it is fully added, the worker
+resumes again, and stopping early isn't actually a problem, since at
+that point the packet wouldn't have yet been added to the encryption
+queue. These properties allow us to avoid disabling interrupts or
+spinning. The design is based on Dmitry Vyukov's algorithm [1].
+
+Performance-wise, ordinarily list-based queues aren't preferable to
+ringbuffers, because of cache misses when following pointers around.
+However, we *already* have to follow the adjacent pointers when working
+through fragments, so there shouldn't actually be any change there. A
+potential downside is that dequeueing is a bit more complicated, but the
+ptr_ring structure used prior had a spinlock when dequeueing, so all and
+all the difference appears to be a wash.
+
+Actually, from profiling, the biggest performance hit, by far, of this
+commit winds up being atomic_add_unless(count, 1, max) and atomic_
+dec(count), which account for the majority of CPU time, according to
+perf. In that sense, the previous ring buffer was superior in that it
+could check if it was full by head==tail, which the list-based approach
+cannot do.
+
+But all and all, this enables us to get massive memory savings, allowing
+WireGuard to scale for real world deployments, without taking much of a
+performance hit.

+Subject: [PATCH] MIPS: select CPU_MIPS64 for remaining MIPS64 CPUs
+
+The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
+distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
+weren't selected by the specialty CPUs, Octeon and Loongson, which meant
+it was possible to hit a weird state of:
+
+ MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
+
+This commit rectifies the issue by having CPU_MIPS64 be selected when
+the missing Octeon or Loongson models are selected.
