crypto: lib/Kconfig - Hide arch options from user commit 17ec3e71ba797cdb62164fea9532c81b60f47167 upstream. The ARCH_MAY_HAVE patch missed arm64, mips and s390. But it may also lead to arch options being enabled but ineffective because of modular/built-in conflicts. As the primary user of all these options wireguard is selecting the arch options anyway, make the same selections at the lib/crypto option level and hide the arch options from the user. Instead of selecting them centrally from lib/crypto, simply set the default of each arch option as suggested by Eric Biggers. Change the Crypto API generic algorithms to select the top-level lib/crypto options instead of the generic one as otherwise there is no way to enable the arch options (Eric Biggers). Introduce a set of INTERNAL options to work around dependency cycles on the CONFIG_CRYPTO symbol.

crypto: lib - implement library version of AES in CFB mode Implement AES in CFB mode using the existing, mostly constant-time generic AES library implementation. This will be used by the TPM code to encrypt communications with TPM hardware, which is often a discrete component connected using sniffable wires or traces. While a CFB template does exist, using a skcipher is a major pain for non-performance critical synchronous crypto where the algorithm is known at compile time and the data is in contiguous buffers with valid kernel virtual addresses.

crypto: remove MODULE_LICENSE in non-modules Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

crypto: curve25519 - Fix selftest build error 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.

crypto: lib - rename 'mod_init' & 'mod_exit' functions to be module-specific Rename module_init & module_exit functions that are named "mod_init" and "mod_exit" so that they are unique in both the System.map file and in initcall_debug output instead of showing up as almost anonymous "mod_init". This is helpful for debugging and in determining how long certain module_init calls take to execute.

crypto: lib/gf128mul - make gf128mul_lle time invariant The gf128mul library has different variants with different memory/performance tradeoffs, where the faster ones use 4k or 64k lookup tables precomputed at runtime, which are based on one of the multiplication factors, which is commonly the key for keyed hash algorithms such as GHASH. The slowest variant is gf128_mul_lle() [and its bbe/ble counterparts], which does not use precomputed lookup tables, but it still relies on a single u16[256] lookup table which is input independent. The use of such a table may cause the execution time of gf128_mul_lle() to correlate with the value of the inputs, which is generally something that must be avoided for cryptographic algorithms. On top of that, the function uses a sequence of if () statements that conditionally invoke be128_xor() based on which bits are set in the second argument of the function, which is usually a pointer to the multiplication factor that represents the key. In order to remove the correlation between the execution time of gf128_mul_lle() and the value of its inputs, let's address the identified shortcomings: - add a time invariant version of gf128mul_x8_lle() that replaces the table lookup with the expression that is used at compile time to populate the lookup table; - make the invocations of be128_xor() unconditional, but pass a zero vector as the third argument if the associated bit in the key is cleared. The resulting code is likely to be significantly slower. However, given that this is the slowest version already, making it even slower in order to make it more secure is assumed to be justified. The bbe and ble counterparts could receive the same treatment, but the former is never used anywhere in the kernel, and the latter is only used in the driver for a asynchronous crypto h/w accelerator (Chelsio), where timing variances are unlikely to matter.
