Precise and non-ambiguous license information is important. The recently added aegis header file has a SPDX license identifier, which is nice, but at the same time it has a contradictionary license boiler plate text. SPDX-License-Identifier: GPL-2.0 versus * This program is free software; you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the Free * Software Foundation; either version 2 of the License, or (at your option) * any later version Oh well. As the other aegis related files are licensed under the GPL v2 or later, it's assumed that the boiler plate code is correct, but the SPDX license identifier is wrong. Fix the SPDX identifier and remove the boiler plate as it is redundant. Fixes: f606a88e ("crypto: aegis - Add generic AEGIS AEAD implementations") Signed-off-by:

For decryption in CBC mode we need to save the last ciphertext block for use as the next IV. However, we were trying to do this also with zero sized ciphertext resulting in a panic. Fix this by only doing the copy if the ciphertext length is at least of IV size. Signed-off-by:

We were copying the last ciphertext block into the IV field for CBC before removing the DMA mapping of the output buffer with the result of the buffer sometime being out-of-sync cache wise and were getting intermittent cases of bad output IV. Fix it by moving the DMA buffer unmapping before the copy. Signed-off-by:

Currently testmgr has separate encryption and decryption test vectors for AEADs. That's massively redundant, since usually the decryption tests are identical to the encryption tests, just with the input/result swapped. And for some algorithms it was forgotten to add decryption test vectors, so for them currently only encryption is being tested. Therefore, eliminate the redundancy by removing the AEAD decryption test vectors and updating testmgr to test both AEAD encryption and decryption using what used to be the encryption test vectors. Naming is adjusted accordingly: each aead_testvec now has a 'ptext' (plaintext), 'plen' (plaintext length), 'ctext' (ciphertext), and 'clen' (ciphertext length) instead of an 'input', 'ilen', 'result', and 'rlen'. "Ciphertext" here refers to the full ciphertext, including the authentication tag. For now the scatterlist divisions are just given for the plaintext length, not also the ciphertext length. For decryption, the last scatterlist element is just extended by the authentication tag length. In total, this removes over 5000 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. The testmgr.h portion of this patch was automatically generated using the following awk script, except that I also manually updated the definition of 'struct aead_testvec' and fixed the location of the comment describing the AEGIS-128 test vectors. BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER } /^static const struct aead_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC } /^static const struct aead_testvec.*_dec_/ { mode = DECVEC } mode == ENCVEC { sub(/\.input[[:space:]]*=/, ".ptext\t=") sub(/\.result[[:space:]]*=/, ".ctext\t=") sub(/\.ilen[[:space:]]*=/, ".plen\t=") sub(/\.rlen[[:space:]]*=/, ".clen\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, 1235 insertions(+), 6491 deletions(-)".

Before this, if akcipher_testvec have `public_key_vec' set to true (i.e. having a public key) only sign/encrypt test is performed, but verify/decrypt test is skipped. With a public key we could do encrypt and verify, but to sign and decrypt a private key is required. This logic is correct for encrypt/decrypt tests (decrypt is skipped if no private key). But incorrect for sign/verify tests - sign is performed no matter if there is no private key, but verify is skipped if there is a public key. Rework `test_akcipher_one' to arrange tests properly depending on value of `public_key_vec` and `siggen_sigver_test'. No tests were missed since there is only one sign/verify test (which have `siggen_sigver_test' set to true) and it has a private key, but future tests could benefit from this improvement.

crypto_init_shash_ops_async() only gives the ahash tfm non-NULL ->export() and ->import() if the underlying shash alg has these non-NULL. This doesn't make sense because when an shash algorithm is registered, shash_prepare_alg() sets a default ->export() and ->import() if the implementor didn't provide them. And elsewhere it's assumed that all shash algs and ahash tfms have non-NULL ->export() and ->import(). Therefore, remove these unnecessary, always-true conditions. Signed-off-by:

Prevent registering shash algorithms that implement ->export() but not ->import(), or ->import() but not ->export(). Such cases don't make sense and could confuse the check that shash_prepare_alg() does for just ->export(). I don't believe this affects any existing algorithms; this is just preventing future mistakes. Signed-off-by:

Some algorithms have a ->setkey() method that is not atomic, in the sense that setting a key can fail after changes were already made to the tfm context. In this case, if a key was already set the tfm can end up in a state that corresponds to neither the old key nor the new key. For example, in gcm.c, if the kzalloc() fails due to lack of memory, then the CTR part of GCM will have the new key but GHASH will not. It's not feasible to make all ->setkey() methods atomic, especially ones that have to key multiple sub-tfms. Therefore, make the crypto API set CRYPTO_TFM_NEED_KEY if ->setkey() fails, to prevent the tfm from being used until a new key is set. [Cc stable mainly because when introducing the NEED_KEY flag I changed AF_ALG to rely on it; and unlike in-kernel crypto API users, AF_ALG previously didn't have this problem. So these "incompletely keyed" states became theoretically accessible via AF_ALG -- though, the opportunities for causing real mischief seem pretty limited.] Fixes: dc26c17f ("crypto: aead - prevent using AEADs without setting key") Cc: <stable@vger.kernel.org> # v4.16+ Signed-off-by:

For example, in lrw.c, if gf128mul_init_64k_bbe() fails due to lack of memory, then priv::table will be left NULL. After that, encryption with that tfm will cause a NULL pointer dereference.

It took me a while to notice the bug where the adiantum template left crypto_spawn::inst == NULL, because this only caused problems in certain cases where algorithms are dynamically loaded/unloaded. More improvements are needed, but for now make crypto_init_spawn() reject this case and WARN(), so this type of bug will be noticed immediately in the future. Note: I checked all callers and the adiantum template was the only place that had this wrong. So this WARN shouldn't trigger anymore. Signed-off-by:

Now that all "blkcipher" templates have been converted to "skcipher", crypto_alloc_instance() is no longer used. And it's not useful any longer as it creates an old-style weakly typed instance rather than a new-style strongly typed instance. So remove it, and now that the name is freed up rename crypto_alloc_instance2() to crypto_alloc_instance(). Signed-off-by:
