-Subject: ath10k-ct: apply mac80211 rates to ath10k-ct rate state
-
-The rates from mac80211 have to be copied to the state of ath10k-ct or
-otherwise the ath10k_check_apply_special_rates function overwrites
-them again with some default values. This breaks for example the
-mcast_rate set for a wifi-iface.

-From: Sebastian Gottschall <s.gottschall@newmedia-net.de>
-
-Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based
-chipsets with on chipset connected led's using WMI Firmware API.  The LED
-device will get available named as "ath10k-phyX" at sysfs and can be controlled
-with various triggers.  adds also debugfs interface for gpio control.
-
-This patch is specific for OpenWRt base, as is use old backported package
-with old wireless source. Support for QCA9984 is removed.
-Reworked to use ath10k-ct custom source

----
-
-v13:
-
-* only compile tested!
-
-* fix all checkpatch warnings
-
-* fix commit log
-
-* sizeof(struct ath10k_gpiocontrol) -> sizeof(*gpio)
-
-* unsigned -> unsigned int
-
-* remove GPIOLIB code, that should be added in a separate patch
-
-* rename gpio.c to leds.c
-
-* add leds.h
-
-* rename some functions:
-
-  ath10k_attach_led() -> ath10k_leds_register()
-  ath10k_unregister_led() -> ath10k_leds_unregister()
-  ath10k_reset_led_pin() -> ath10k_leds_start()
-
-* call ath10k_leds_unregister() before ath10k_thermal_unregister() to preserve ordering
-
-* call ath10k_leds_start() only from ath10k_core_start() and not from mac.c
-
-* rename struct ath10k_gpiocontrol as anonymous function under struct
-  ath10k::leds, no need for memory allocation
-
-* merge ath10k_add_led() to ath10k_attach_led(), which is it's only caller
-
-* remove #if IS_ENABLED() checks from most of places, memory savings from those were not worth it
-
-* Kconfig help text improvement and move it lower in the menu, also don't enable it by default
-
-* switch to set_brightness_blocking() so that the callback can sleep,
-  then no need to use ath10k_wmi_cmd_send_nowait() and can take mutex
-  to access ar->state
-
-* don't touch ath10k_wmi_pdev_get_temperature()
-
-* as QCA6174/QCA9377 are not (yet) supported don't add the command to WMI-TLV interface
-
-* remove debugfs interface, that should be added in another patch
-
-* cleanup includes

-
-config BATMAN_ADV_NC
-	bool "Network Coding"
-	depends on PACKAGE_kmod-batman-adv
-	help
-	  This option enables network coding, a mechanism that aims to
-	  increase the overall network throughput by fusing multiple
-	  packets in one transmission.
-	  Note that interfaces controlled by batman-adv must be manually
-	  configured to have promiscuous mode enabled in order to make
-	  network coding work.
-	  If you think that your network does not need this feature you
-	  can safely disable it and save some space.
-
-config BATMAN_ADV_MCAST

-	  log_level setting.
-
-config BATMAN_ADV_SYSFS
-	bool "batman-adv sysfs entries"

-	help
-	  Say Y here if you want to enable batman-adv device configuration and

-Subject: [PATCH] modpost: add a helper to get data pointed by a symbol
-
-When CONFIG_MODULE_REL_CRCS is enabled, the value of __crc_* is not
-an absolute value, but the address to the CRC data embedded in the
-.rodata section.
-
-Getting the data pointed by the symbol value is somewhat complex.
-Split it out into a new helper, sym_get_data().
-
-I will reuse it to refactor namespace_from_kstrtabns() in the next
-commit.

-Subject: [PATCH] modpost: refactor namespace_from_kstrtabns() to not hard-code
- section name
-
-Currently, namespace_from_kstrtabns() relies on the fact that
-namespace strings are recorded in the __ksymtab_strings section.
-Actually, it is coded in include/linux/export.h, but modpost does
-not need to hard-code the section name.
-
-Elf_Sym::st_shndx holds the index of the relevant section. Using it is
-a more portable way to get the namespace string.
-
-Make namespace_from_kstrtabns() simply call sym_get_data(), and delete
-the info->ksymtab_strings .
-
-While I was here, I added more 'const' qualifiers to pointers.

-Subject: [PATCH] arm64: Implement optimised checksum routine
-
-Apparently there exist certain workloads which rely heavily on software
-checksumming, for which the generic do_csum() implementation becomes a
-significant bottleneck. Therefore let's give arm64 its own optimised
-version - for ease of maintenance this foregoes assembly or intrisics,
-and is thus not actually arm64-specific, but does rely heavily on C
-idioms that translate well to the A64 ISA and the typical load/store
-capabilities of most ARMv8 CPU cores.
-
-The resulting increase in checksum throughput scales nicely with buffer
-size, tending towards 4x for a small in-order core (Cortex-A53), and up
-to 6x or more for an aggressive big core (Ampere eMAG).

-Subject: [PATCH] arm64: csum: Fix pathological zero-length calls
-
-In validating the checksumming results of the new routine, I sadly
-neglected to test its not-checksumming results. Thus it slipped through
-that the one case where @buff is already dword-aligned and @len = 0
-manages to defeat the tail-masking logic and behave as if @len = 8.
-For a zero length it doesn't make much sense to deference @buff anyway,
-so just add an early return (which has essentially zero impact on
-performance).

-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.

-
-Given that calls into the library API will always go through the

-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)

-Subject: [PATCH] crypto: arm64/chacha - expose arm64 ChaCha routine as library
- 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).

-+ * 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.

-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).

-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.

-From: Ard Biesheuvel <ardb@kernel.org>
-Date: Fri, 8 Nov 2019 13:22:18 +0100
-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: 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: 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.

- 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: 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.

- 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.
