From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- crypto/sm3.c | 89 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 crypto/sm3.c (limited to 'crypto/sm3.c') diff --git a/crypto/sm3.c b/crypto/sm3.c new file mode 100644 index 000000000..05111a99b --- /dev/null +++ b/crypto/sm3.c @@ -0,0 +1,89 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * SM3 secure hash, as specified by OSCCA GM/T 0004-2012 SM3 and + * described at https://tools.ietf.org/html/draft-shen-sm3-hash-01 + * + * Copyright (C) 2017 ARM Limited or its affiliates. + * Written by Gilad Ben-Yossef + * Copyright (C) 2021 Tianjia Zhang + * Copyright 2026 Google LLC + */ + +#include +#include +#include +#include + +#define SM3_CTX(desc) ((struct sm3_ctx *)shash_desc_ctx(desc)) + +static int crypto_sm3_init(struct shash_desc *desc) +{ + sm3_init(SM3_CTX(desc)); + return 0; +} + +static int crypto_sm3_update(struct shash_desc *desc, + const u8 *data, unsigned int len) +{ + sm3_update(SM3_CTX(desc), data, len); + return 0; +} + +static int crypto_sm3_final(struct shash_desc *desc, u8 *out) +{ + sm3_final(SM3_CTX(desc), out); + return 0; +} + +static int crypto_sm3_digest(struct shash_desc *desc, + const u8 *data, unsigned int len, u8 *out) +{ + sm3(data, len, out); + return 0; +} + +static int crypto_sm3_export_core(struct shash_desc *desc, void *out) +{ + memcpy(out, SM3_CTX(desc), sizeof(struct sm3_ctx)); + return 0; +} + +static int crypto_sm3_import_core(struct shash_desc *desc, const void *in) +{ + memcpy(SM3_CTX(desc), in, sizeof(struct sm3_ctx)); + return 0; +} + +static struct shash_alg sm3_alg = { + .base.cra_name = "sm3", + .base.cra_driver_name = "sm3-lib", + .base.cra_priority = 300, + .base.cra_blocksize = SM3_BLOCK_SIZE, + .base.cra_module = THIS_MODULE, + .digestsize = SM3_DIGEST_SIZE, + .init = crypto_sm3_init, + .update = crypto_sm3_update, + .final = crypto_sm3_final, + .digest = crypto_sm3_digest, + .export_core = crypto_sm3_export_core, + .import_core = crypto_sm3_import_core, + .descsize = sizeof(struct sm3_ctx), +}; + +static int __init crypto_sm3_mod_init(void) +{ + return crypto_register_shash(&sm3_alg); +} +module_init(crypto_sm3_mod_init); + +static void __exit crypto_sm3_mod_exit(void) +{ + crypto_unregister_shash(&sm3_alg); +} +module_exit(crypto_sm3_mod_exit); + +MODULE_LICENSE("GPL v2"); +MODULE_DESCRIPTION("Crypto API support for SM3"); + +MODULE_ALIAS_CRYPTO("sm3"); +MODULE_ALIAS_CRYPTO("sm3-lib"); -- cgit v1.3.1
