2022-08-26crypto: Kconfig - add submenusRobert Elliott
Convert each comment section into a submenu: Cryptographic API Crypto core or helper Public-key cryptography Block ciphers Length-preserving ciphers and modes AEAD (authenticated encryption with associated data) ciphers Hashes, digests, and MACs CRCs (cyclic redundancy checks) Compression Random number generation Userspace interface That helps find entries (e.g., searching for a name like SHA512 doesn't just report the location is Main menu -> Cryptography API, leaving you to wade through 153 entries; it points you to the Digests page).

2022-08-19crypto: testmgr - don't generate WARN for missing modulesRobert Elliott
This userspace command: modprobe tcrypt or modprobe tcrypt mode=0 runs all the tcrypt test cases numbered <200 (i.e., all the test cases calling tcrypt_test() and returning return values). Tests are sparsely numbered from 0 to 1000. For example: modprobe tcrypt mode=12 tests sha512, and modprobe tcrypt mode=152 tests rfc4543(gcm(aes))) - AES-GCM as GMAC The test manager generates WARNING crashdumps every time it attempts a test using an algorithm that is not available (not built-in to the kernel or available as a module): alg: skcipher: failed to allocate transform for ecb(arc4): -2 ------------[ cut here ]----------- alg: self-tests for ecb(arc4) (ecb(arc4)) failed (rc=-2) WARNING: CPU: 9 PID: 4618 at crypto/testmgr.c:5777 alg_test+0x30b/0x510 [50 more lines....] ---[ end trace 0000000000000000 ]--- If the kernel is compiled with CRYPTO_USER_API_ENABLE_OBSOLETE disabled (the default), then these algorithms are not compiled into the kernel or made into modules and trigger WARNINGs: arc4 tea xtea khazad anubis xeta seed Additionally, any other algorithms that are not enabled in .config will generate WARNINGs. In RHEL 9.0, for example, the default selection of algorithms leads to 16 WARNING dumps. One attempt to fix this was by modifying tcrypt_test() to check crypto_has_alg() and immediately return 0 if crypto_has_alg() fails, rather than proceed and return a non-zero error value that causes the caller (alg_test() in crypto/testmgr.c) to invoke WARN(). That knocks out too many algorithms, though; some combinations like ctr(des3_ede) would work. Instead, change the condition on the WARN to ignore a return value is ENOENT, which is the value returned when the algorithm or combination of algorithms doesn't exist. Add a pr_warn to communicate that information in case the WARN is skipped. This approach allows algorithm tests to work that are combinations, not provided by one driver, like ctr(blowfish). Result - no more WARNINGs: modprobe tcrypt [ 115.541765] tcrypt: testing md5 [ 115.556415] tcrypt: testing sha1 [ 115.570463] tcrypt: testing ecb(des) [ 115.585303] cryptomgr: alg: skcipher: failed to allocate transform for ecb(des): -2 [ 115.593037] cryptomgr: alg: self-tests for ecb(des) using ecb(des) failed (rc=-2) [ 115.593038] tcrypt: testing cbc(des) [ 115.610641] cryptomgr: alg: skcipher: failed to allocate transform for cbc(des): -2 [ 115.618359] cryptomgr: alg: self-tests for cbc(des) using cbc(des) failed (rc=-2) ...

2022-08-19crypto: lib - move __crypto_xor into utilsEric Biggers
CRYPTO_LIB_CHACHA depends on CRYPTO for __crypto_xor, defined in crypto/algapi.c. This is a layering violation because the dependencies should only go in the other direction (crypto/ => lib/crypto/). Also the correct dependency would be CRYPTO_ALGAPI, not CRYPTO. Fix this by moving __crypto_xor into the utils module in lib/crypto/. Note that CRYPTO_LIB_CHACHA_GENERIC selected XOR_BLOCKS, which is unrelated and unnecessary. It was perhaps thought that XOR_BLOCKS was needed for __crypto_xor, but that's not the case.

As more crypto library utilities are being added, this creates a single place for them to go without cluttering up the main lib directory. The module's main file will be lib/crypto/utils.c.

2022-08-10crypto: blake2b: effectively disable frame size warningLinus Torvalds
It turns out that gcc-12.1 has some nasty problems with register allocation on a 32-bit x86 build for the 64-bit values used in the generic blake2b implementation, where the pattern of 64-bit rotates and xor operations ends up making gcc generate horrible code. As a result it ends up with a ridiculously large stack frame for all the spills it generates, resulting in the following build problem: crypto/blake2b_generic.c: In function ‘blake2b_compress_one_generic’: crypto/blake2b_generic.c:109:1: error: the frame size of 2640 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] on the same test-case, clang ends up generating a stack frame that is just 296 bytes (and older gcc versions generate a slightly bigger one at 428 bytes - still nowhere near that almost 3kB monster stack frame of gcc-12.1). The issue is fixed both in mainline and the GCC 12 release branch [1], but current release compilers end up failing the i386 allmodconfig build due to this issue. Disable the warning for now by simply raising the frame size for this one file, just to keep this issue from having people turn off WERROR.

2022-08-03KEYS: asymmetric: enforce SM2 signature use pkey algoTianjia Zhang
The signature verification of SM2 needs to add the Za value and recalculate sig->digest, which requires the detection of the pkey_algo in public_key_verify_signature(). As Eric Biggers said, the pkey_algo field in sig is attacker-controlled and should be use pkey->pkey_algo instead of sig->pkey_algo, and secondly, if sig->pkey_algo is NULL, it will also cause signature verification failure. The software_key_determine_akcipher() already forces the algorithms are matched, so the SM3 algorithm is enforced in the SM2 signature, although this has been checked, we still avoid using any algorithm information in the signature as input.

2022-07-15crypto: lib - make the sha1 library optionalEric Biggers
Since the Linux RNG no longer uses sha1_transform(), the SHA-1 library is no longer needed unconditionally. Make it possible to build the Linux kernel without the SHA-1 library by putting it behind a kconfig option, and selecting this new option from the kconfig options that gate the remaining users: CRYPTO_SHA1 for crypto/sha1_generic.c, BPF for kernel/bpf/core.c, and IPV6 for net/ipv6/addrconf.c. Unfortunately, since BPF is selected by NET, for now this can only make a difference for kernels built without networking support.

Changes from v1: * replace some accidental spaces with tabs In commit f145d411a67e ("crypto: rsa - implement Chinese Remainder Theorem for faster private key operations") we have started to use the additional primes and coefficients for RSA private key operations. However, these additional parameters are not present (defined as 0 integers) in the RSA test vectors. Some parameters were borrowed from OpenSSL, so I was able to find the source. I could not find the public source for 1 vector though, so had to recover the parameters by implementing Appendix C from [1].

2022-06-24crypto: rsa - implement Chinese Remainder Theorem for faster private key ↵Ignat Korchagin
operations Changes from v1: * exported mpi_sub and mpi_mul, otherwise the build fails when RSA is a module The kernel RSA ASN.1 private key parser already supports only private keys with additional values to be used with the Chinese Remainder Theorem [1], but these values are currently not used. This rudimentary CRT implementation speeds up RSA private key operations for the following Go benchmark up to ~3x. This implementation also tries to minimise the allocation of additional MPIs, so existing MPIs are reused as much as possible (hence the variable names are a bit weird). The benchmark used: ``` package keyring_test import ( "crypto" "crypto/rand" "crypto/rsa" "crypto/x509" "io" "syscall" "testing" "unsafe" ) type KeySerial int32 type Keyring int32 const ( KEY_SPEC_PROCESS_KEYRING Keyring = -2 KEYCTL_PKEY_SIGN = 27 ) var ( keyTypeAsym = []byte("asymmetric\x00") sha256pkcs1 = []byte("enc=pkcs1 hash=sha256\x00") ) func (keyring Keyring) LoadAsym(desc string, payload []byte) (KeySerial, error) { cdesc := []byte(desc + "\x00") serial, _, errno := syscall.Syscall6(syscall.SYS_ADD_KEY, uintptr(unsafe.Pointer(&keyTypeAsym[0])), uintptr(unsafe.Pointer(&cdesc[0])), uintptr(unsafe.Pointer(&payload[0])), uintptr(len(payload)), uintptr(keyring), uintptr(0)) if errno == 0 { return KeySerial(serial), nil } return KeySerial(serial), errno } type pkeyParams struct { key_id KeySerial in_len uint32 out_or_in2_len uint32 __spare [7]uint32 } // the output signature buffer is an input parameter here, because we want to // avoid Go buffer allocation leaking into our benchmarks func (key KeySerial) Sign(info, digest, out []byte) error { var params pkeyParams params.key_id = key params.in_len = uint32(len(digest)) params.out_or_in2_len = uint32(len(out)) _, _, errno := syscall.Syscall6(syscall.SYS_KEYCTL, KEYCTL_PKEY_SIGN, uintptr(unsafe.Pointer(&params)), uintptr(unsafe.Pointer(&info[0])), uintptr(unsafe.Pointer(&digest[0])), uintptr(unsafe.Pointer(&out[0])), uintptr(0)) if errno == 0 { return nil } return errno } func BenchmarkSign(b *testing.B) { priv, err := rsa.GenerateKey(rand.Reader, 2048) if err != nil { b.Fatalf("failed to generate private key: %v", err) } pkcs8, err := x509.MarshalPKCS8PrivateKey(priv) if err != nil { b.Fatalf("failed to serialize the private key to PKCS8 blob: %v", err) } serial, err := KEY_SPEC_PROCESS_KEYRING.LoadAsym("test rsa key", pkcs8) if err != nil { b.Fatalf("failed to load the private key into the keyring: %v", err) } b.Logf("loaded test rsa key: %v", serial) digest := make([]byte, 32) _, err = io.ReadFull(rand.Reader, digest) if err != nil { b.Fatalf("failed to generate a random digest: %v", err) } sig := make([]byte, 256) for n := 0; n < b.N; n++ { err = serial.Sign(sha256pkcs1, digest, sig) if err != nil { b.Fatalf("failed to sign the digest: %v", err) } } err = rsa.VerifyPKCS1v15(&priv.PublicKey, crypto.SHA256, digest, sig) if err != nil { b.Fatalf("failed to verify the signature: %v", err) } } ``` [1]: https://en.wikipedia.org/wiki/RSA_(cryptosystem)#Using_the_Chinese_remainder_algorithm Signed-off-by: Ignat Korchagin <ignat@cloudflare.com> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
