When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

Recent AEAD changes in testmgr framework introduced by commit a0d608ee ("crypto: testmgr - unify the AEAD encryption and decryption test vectors") uncovered an error in the CAAM drivers, since they don't correctly handle the case when AEAD output length is zero. Add checks to avoid feeding zero-length req->dst to DMA API. Signed-off-by:

Add cmac(aes) keyed hash offloading support. Similar to xcbc implementation, driver must make sure there are still some bytes buffered when ahash_final() is called. This way HW is able to decide whether padding is needed and which key to derive (L -> K1 / K2) for the last block. Signed-off-by:

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by:

The virtio-rng driver uses a completion called have_data to wait for a virtio read to be fulfilled by the hypervisor. The completion is reset before placing a buffer on the virtio queue and completed by the virtio callback once data has been written into the buffer. Prior to this commit, the driver called init_completion on this completion both during probe as well as when registering virtio buffers as part of a hwrng read operation. The second of these init_completion calls should instead be reinit_completion because the have_data completion has already been inited by probe. As described in Documentation/scheduler/completion.txt, "Calling init_completion() twice on the same completion object is most likely a bug". This bug was present in the initial implementation of virtio-rng in f7f510ec ("virtio: An entropy device, as suggested by hpa"). Back then the have_data completion was a single static completion rather than a member of one of potentially multiple virtrng_info structs as implemented later by 08e53fbd ("virtio-rng: support multiple virtio-rng devices"). The original driver incorrectly used init_completion rather than INIT_COMPLETION to reset have_data during read. Tested by running `head -c48 /dev/random | hexdump` within crosvm, the Chrome OS virtual machine monitor, and confirming that the virtio-rng driver successfully produces random bytes from the host.

Precise and non-ambiguous license information is important. The recently added morus header files have a SPDX license identifier, which is nice, but at the same time they have a contradictionary license boiler plate text.

As the other morus 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.

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(-)". Signed-off-by: -
