2020-06-24crypto: omap-sham - add proper load balancing support for multicoreTero Kristo1-33/+31
[ Upstream commit 281c377872ff5d15d80df25fc4df02d2676c7cde ] The current implementation of the multiple accelerator core support for OMAP SHA does not work properly. It always picks up the first probed accelerator core if this is available, and rest of the book keeping also gets confused if there are two cores available. Add proper load balancing support for SHA, and also fix any bugs related to the multicore support while doing it.

2020-06-17crypto: virtio: Fix use-after-free in virtio_crypto_skcipher_finalize_req()Longpeng(Mike)1-2/+3
[ Upstream commit 8c855f0720ff006d75d0a2512c7f6c4f60ff60ee ] 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.

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.

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.

AMD Seattle incorporates a non-PCI version of the v3 CCP crypto accelerator, and this version was left behind when the maximum RSA modulus size was parameterized in order to support v5 hardware which supports larger moduli than v3 hardware does.

commit 1372a51b88fa0d5a8ed2803e4975c98da3f08463 upstream. 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.

commit bd56cea012fc2d6381e8cd3209510ce09f9de8c9 upstream. The chelsio crypto driver is casting 'struct crypto_aead' directly to 'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the first field of 'struct crypto_aead'. Consequently, the calls to crypto_tfm_set_flags() are modifying some other field in the struct. Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in ->setauthsize(), not just in ->setkey(). This is incorrect since this flag is for bad key lengths, not for bad authentication tag lengths. Fix these bugs by removing the broken crypto_tfm_set_flags() calls from ->setauthsize() and by fixing them in ->setkey().

commit 4549f7e5aa27ffc2cba63b5db8842a3b486f5688 upstream. The geode AES driver is heavily broken because it stores per-request state in the transform context. So it will crash or produce the wrong result if used by any of the many places in the kernel that issue concurrent requests for the same transform object. This driver is also implemented using the deprecated blkcipher API, which makes it difficult to fix, and puts it among the drivers preventing that API from being removed. Convert this driver to use the skcipher API, and change it to not store per-request state in the transform context.

[ Upstream commit 4ee812f6143d78d8ba1399671d78c8d78bf2817c ] In the vmx crypto Makefile we assign to a variable called TARGET and pass that to the aesp8-ppc.pl and ghashp8-ppc.pl scripts. The variable is meant to describe what flavour of powerpc we're building for, eg. either 32 or 64-bit, and big or little endian. Unfortunately TARGET is a fairly common name for a make variable, and if it happens that TARGET is specified as a command line parameter to make, the value specified on the command line will override our value. In particular this can happen if the kernel Makefile is driven by an external Makefile that uses TARGET for something. This leads to weird build failures, eg: nonsense at /build/linux/drivers/crypto/vmx/ghashp8-ppc.pl line 45. /linux/drivers/crypto/vmx/Makefile:20: recipe for target 'drivers/crypto/vmx/ghashp8-ppc.S' failed Which shows that we passed an empty value for $(TARGET) to the perl script, confirmed with make V=1: perl /linux/drivers/crypto/vmx/ghashp8-ppc.pl > drivers/crypto/vmx/ghashp8-ppc.S We can avoid this confusion by using override, to tell make that we don't want anything to override our variable, even a value specified on the command line. We can also use a less common name, given the script calls it "flavour", let's use that.

So, just initialize the list head to avoid the problem.

2019-12-13crypto: geode-aes - switch to skcipher for cbc(aes) fallbackArd Biesheuvel2-25/+34
commit 504582e8e40b90b8f8c58783e2d1e4f6a2b71a3a upstream. Commit 79c65d179a40e145 ("crypto: cbc - Convert to skcipher") updated the generic CBC template wrapper from a blkcipher to a skcipher algo, to get away from the deprecated blkcipher interface. However, as a side effect, drivers that instantiate CBC transforms using the blkcipher as a fallback no longer work, since skciphers can wrap blkciphers but not the other way around. This broke the geode-aes driver. So let's fix it by moving to the sync skcipher interface when allocating the fallback. At the same time, align with the generic API for ECB and CBC by rejecting inputs that are not a multiple of the AES block size.
