In some cases the CCB DMA-based internal transfer started by the MOVE command (src=M3 register, dst=descriptor buffer) does not finish in time and DECO executes the unpatched descriptor. This leads eventually to a DECO Watchdog Timer timeout error. To make sure the transfer ends, change the MOVE command to be blocking. Signed-off-by:

Management Complex (MC) f/w detection is based on CTPR_MS[DPAA2] bit. This is incorrect since: -the bit is set for all CAAM blocks integrated in SoCs with a certain Layerscape Chassis -some SoCs with LS Chassis don't have an MC block (thus no MC f/w) To fix this, MC f/w detection will be based on the presence of "fsl,qoriq-mc" compatible string in the device tree. Fixes: 297b9ceb ("crypto: caam/jr - add support for DPAA2 parts") Signed-off-by:

Several source files have been taken from OpenSSL. In some of them a comment that "permission to use under GPL terms is granted" was included below a contradictory license statement. In several cases, there was no indication that the license of the code was compatible with the GPLv2. This change clarifies the licensing for all of these files. I've confirmed with the author (Andy Polyakov) that a) he has licensed the files with the GPLv2 comment under that license and b) that he's also happy to license the other files under GPLv2 too. In one case, the file is already contained in his CRYPTOGAMS bundle, which has a GPLv2 option, and so no special measures are needed. In all cases, the license status of code has been clarified by making the GPLv2 license prominent. The .S files have been regenerated from the updated .pl files. This is a comment-only change. No code is changed. Signed-off-by:

Commit 56e8e57f ("crypto: morus - Add common SIMD glue code for MORUS") accidetally consiedered the glue code to be usable by different architectures, but it seems to be only usable on x86. This patch moves it under arch/x86/crypto and adds 'depends on X86' to the Kconfig options and also removes the prompt to hide these internal options from the user. Reported-by:

Currently testmgr has separate encryption and decryption test vectors for symmetric ciphers. That's massively redundant, since with few exceptions (mostly mistakes, apparently), all decryption tests are identical to the encryption tests, just with the input/result flipped. Therefore, eliminate the redundancy by removing the decryption test vectors and updating testmgr to test both encryption and decryption using what used to be the encryption test vectors. Naming is adjusted accordingly: each cipher_testvec now has a 'ptext' (plaintext), 'ctext' (ciphertext), and 'len' instead of an 'input', 'result', 'ilen', and 'rlen'. Note that it was always the case that 'ilen == rlen'. AES keywrap ("kw(aes)") is special because its IV is generated by the encryption. Previously this was handled by specifying 'iv_out' for encryption and 'iv' for decryption. To make it work cleanly with only one set of test vectors, put the IV in 'iv', remove 'iv_out', and add a boolean that indicates that the IV is generated by the encryption. In total, this removes over 10000 lines from testmgr.h, with no reduction in test coverage since prior patches already copied the few unique decryption test vectors into the encryption test vectors. This covers all algorithms that used 'struct cipher_testvec', e.g. any block cipher in the ECB, CBC, CTR, XTS, LRW, CTS-CBC, PCBC, OFB, or keywrap modes, and Salsa20 and ChaCha20. No change is made to AEAD tests, though we probably can eliminate a similar redundancy there too. The testmgr.h portion of this patch was automatically generated using the following awk script, with some slight manual fixups on top (updated 'struct cipher_testvec' definition, updated a few comments, and fixed up the AES keywrap test vectors): BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER } /^static const struct cipher_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC } /^static const struct cipher_testvec.*_dec_/ { mode = DECVEC } mode == ENCVEC && !/\.ilen[[:space:]]*=/ { sub(/\.input[[:space:]]*=$/, ".ptext =") sub(/\.input[[:space:]]*=/, ".ptext\t=") sub(/\.result[[:space:]]*=$/, ".ctext =") sub(/\.result[[:space:]]*=/, ".ctext\t=") sub(/\.rlen[[:space:]]*=/, ".len\t=") print } mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER } mode == OTHER { print } mode == ENCVEC && /^};/ { mode = OTHER } mode == DECVEC && /^};/ { mode = DECVEC_TAIL } Note that git's default diff algorithm gets confused by the testmgr.h portion of this patch, and reports too many lines added and removed. It's better viewed with 'git diff --minimal' (or 'git show --minimal'), which reports "2 files changed, 919 insertions(+), 11723 deletions(-)".

One "cbc(des)" decryption test vector doesn't exactly match an encryption test vector with input and result swapped. It's *almost* the same as one, but the decryption version is "chunked" while the encryption version is "unchunked". In preparation for removing the decryption test vectors, make the encryption one both chunked and unchunked, so we don't lose any test coverage. Signed-off-by:

crc32c has an unkeyed test vector but crc32 did not. Add the crc32c one (which uses an empty input) to crc32 too, and also add a new one to both that uses a nonempty input. These test vectors verify that crc32 and crc32c implementations use the correct default initial state. Signed-off-by:

Since testmgr uses a single tfm for all tests of each hash algorithm, once a key is set the tfm won't be unkeyed anymore. But with crc32 and crc32c, the key is really the "default initial state" and is optional; those algorithms should have both keyed and unkeyed test vectors, to verify that implementations use the correct default key. Simply listing the unkeyed test vectors first isn't guaranteed to work yet because testmgr makes multiple passes through the test vectors. crc32c does have an unkeyed test vector listed first currently, but it only works by chance because the last crc32c test vector happens to use a key that is the same as the default key. Therefore, teach testmgr to split hash test vectors into unkeyed and keyed sections, and do all the unkeyed ones before the keyed ones. Signed-off-by:

The Blackfin CRC driver was removed by commit 9678a8dc ("crypto: bfin_crc - remove blackfin CRC driver"), but it was forgotten to remove the corresponding "hmac(crc32)" test vectors. I see no point in keeping them since nothing else appears to implement or use "hmac(crc32)", which isn't an algorithm that makes sense anyway because HMAC is meant to be used with a cryptographically secure hash function, which CRC's are not. Thus, remove the unneeded test vectors. Signed-off-by:

crc32c-generic sets an alignmask, but actually its ->update() works with any alignment; only its ->setkey() and outputting the final digest assume an alignment. To prevent the buffer from having to be aligned by the crypto API for just these cases, switch these cases over to the unaligned access macros and remove the cra_alignmask. Note that this also makes crc32c-generic more consistent with crc32-generic. Signed-off-by:

crc32-generic doesn't have a cra_alignmask set, which is desired as its ->update() works with any alignment. However, it incorrectly assumes 4-byte alignment in ->setkey() and when outputting the final digest. Fix this by using the unaligned access macros in those cases. Signed-off-by:

In do_chtls_setsockopt(), the tls crypto info is first copied from the poiner 'optval' in userspace and saved to 'tmp_crypto_info'. Then the 'version' of the crypto info is checked. If the version is not as expected, i.e., TLS_1_2_VERSION, error code -ENOTSUPP is returned to indicate that the provided crypto info is not supported yet. Then, the 'cipher_type' field of the 'tmp_crypto_info' is also checked to see if it is TLS_CIPHER_AES_GCM_128. If it is, the whole struct of tls12_crypto_info_aes_gcm_128 is copied from the pointer 'optval' and then the function chtls_setkey() is invoked to set the key. Given that the 'optval' pointer resides in userspace, a malicious userspace process can race to change the data pointed by 'optval' between the two copies. For example, a user can provide a crypto info with TLS_1_2_VERSION and TLS_CIPHER_AES_GCM_128. After the first copy, the user can modify the 'version' and the 'cipher_type' fields to any versions and/or cipher types that are not allowed. This way, the user can bypass the checks, inject bad data to the kernel, cause chtls_setkey() to set a wrong key or other issues. This patch reuses the data copied in the first try so as to ensure these checks will not be bypassed. Signed-off-by:

This patches reworks the way the algorithm type is set in the context, by using the fact that the decryption algorithms are just a combination of the algorithm encryption type and CONTEXT_CONTROL_TYPE_NULL_IN.

This patch adds optimized implementations of MORUS-640 and MORUS-1280, utilizing the SSE2 and AVX2 x86 extensions. For MORUS-1280 (which operates on 256-bit blocks) we provide both AVX2 and SSE2 implementation. Although SSE2 MORUS-1280 is slower than AVX2 MORUS-1280, it is comparable in speed to the SSE2 MORUS-640. Signed-off-by:
