2020-06-17crypto: virtio: Fix src/dst scatterlist calculation in ↵Longpeng(Mike)
__virtio_crypto_skcipher_do_req() commit b02989f37fc5e865ceeee9070907e4493b3a21e2 upstream. The system will crash when the users insmod crypto/tcrypt.ko with mode=38 ( testing "cts(cbc(aes))" ). Usually the next entry of one sg will be @sg@ + 1, but if this sg element is part of a chained scatterlist, it could jump to the start of a new scatterlist array. Fix it by sg_next() on calculation of src/dst scatterlist.

2020-06-17crypto: virtio: Fix use-after-free in virtio_crypto_skcipher_finalize_req()Longpeng(Mike)
commit 8c855f0720ff006d75d0a2512c7f6c4f60ff60ee upstream. The system'll crash when the users insmod crypto/tcrypto.ko with mode=155 ( testing "authenc(hmac(sha1),cbc(aes))" ). It's caused by reuse the memory of request structure. In crypto_authenc_init_tfm(), the reqsize is set to: [PART 1] sizeof(authenc_request_ctx) + [PART 2] ictx->reqoff + [PART 3] MAX(ahash part, skcipher part) and the 'PART 3' is used by both ahash and skcipher in turn. When the virtio_crypto driver finish skcipher req, it'll call ->complete callback(in crypto_finalize_skcipher_request) and then free its resources whose pointers are recorded in 'skcipher parts'. However, the ->complete is 'crypto_authenc_encrypt_done' in this case, it will use the 'ahash part' of the request and change its content, so virtio_crypto driver will get the wrong pointer after ->complete finish and mistakenly free some other's memory. So the system will crash when these memory will be used again. The resources which need to be cleaned up are not used any more. But the pointers of these resources may be changed in the function "crypto_finalize_skcipher_request". Thus release specific resources before calling this function.

For skcipher algorithms, the input, output HW S/G tables look like this: [IV, src][dst, IV] Now, we can have 2 conditions here: - there is no IV; - src and dst are equal (in-place encryption) and scattered and the error is an "off-by-one" in the HW S/G table.

2020-05-02Crypto: chelsio - Fixes a hang issue during driver registrationAyush Sawal
commit ad59ddd02de26271b89564962e74d689f1a30b49 upstream. This issue occurs only when multiadapters are present. Hang happens because assign_chcr_device returns u_ctx pointer of adapter which is not yet initialized as for this adapter cxgb_up is not been called yet. The last_dev pointer is used to determine u_ctx pointer and it is initialized two times in chcr_uld_add in chcr_dev_add respectively. The fix here is don't initialize the last_dev pointer during chcr_uld_add. Only assign to value to it when the adapter's initialization is completed i.e in chcr_dev_add.

2020-04-23crypto: qce - use cryptlen when adding extra sglEneas U de Queiroz
[ Upstream commit d6364b8128439a8c0e381f80c38667de9f15eef8 ] The qce crypto driver appends an extra entry to the dst sgl, to maintain private state information. When the gcm driver sends requests to the ctr skcipher, it passes the authentication tag after the actual crypto payload, but it must not be touched. Commit 1336c2221bee ("crypto: qce - save a sg table slot for result buf") limited the destination sgl to avoid overwriting the authentication tag but it assumed the tag would be in a separate sgl entry. This is not always the case, so it is better to limit the length of the destination buffer to req->cryptlen before appending the result buf.

2020-04-17crypto: caam/qi2 - fix chacha20 data size errorHoria Geantă
commit 3a5a9e1ef37b030b836d92df8264f840988f4a38 upstream. HW generates a Data Size error for chacha20 requests that are not a multiple of 64B, since algorithm state (AS) does not have the FINAL bit set. Since updating req->iv (for chaining) is not required, modify skcipher descriptors to set the FINAL bit for chacha20. [Note that for skcipher decryption we know that ctx1_iv_off is 0, which allows for an optimization by not checking algorithm type, since append_dec_op1() sets FINAL bit for all algorithms except AES.] Also drop the descriptor operations that save the IV. However, in order to keep code logic simple, things like S/G tables generation etc. are not touched.

2020-01-16crypto: vmx - reject xts inputs that are too shortDaniel Axtens
When the kernel XTS implementation was extended to deal with ciphertext stealing in commit 8083b1bf8163 ("crypto: xts - add support for ciphertext stealing"), a check was added to reject inputs that were too short. However, in the vmx enablement - commit 239668419349 ("crypto: vmx/xts - use fallback for ciphertext stealing"), that check wasn't added to the vmx implementation. This disparity leads to errors like the following: alg: skcipher: p8_aes_xts encryption unexpectedly succeeded on test vector "random: len=0 klen=64"; expected_error=-22, cfg="random: inplace may_sleep use_finup src_divs=[<flush>66.99%@+10, 33.1%@alignmask+1155]" Return -EINVAL if asked to operate with a cryptlen smaller than the AES block size. This brings vmx in line with the generic implementation.
