crypto: Replaced gcc specific attributes with macros from compiler.h Continuing from this commit: 52f5684c8e1e ("kernel: use macros from compiler.h instead of __attribute__((...))") I submitted 4 total patches. They are part of task I've taken up to increase compiler portability in the kernel. I've cleaned up the subsystems under /kernel /mm /block and /security, this patch targets /crypto. There is <linux/compiler.h> which provides macros for various gcc specific constructs. Eg: __weak for __attribute__((weak)). I've cleaned all instances of gcc specific attributes with the right macros for the crypto subsystem. I had to make one additional change into compiler-gcc.h for the case when one wants to use this: __attribute__((aligned) and not specify an alignment factor. From the gcc docs, this will result in the largest alignment for that data type on the target machine so I've named the macro __aligned_largest. Please advise if another name is more appropriate.

crypto: remove propagation of CRYPTO_TFM_RES_* flags The CRYPTO_TFM_RES_* flags were apparently meant as a way to make the ->setkey() functions provide more information about errors. But these flags weren't actually being used or tested, and in many cases they weren't being set correctly anyway. So they've now been removed. Also, if someone ever actually needs to start better distinguishing ->setkey() errors (which is somewhat unlikely, as this has been unneeded for a long time), we'd be much better off just defining different return values, like -EINVAL if the key is invalid for the algorithm vs. -EKEYREJECTED if the key was rejected by a policy like "no weak keys". That would be much simpler, less error-prone, and easier to test. So just remove CRYPTO_TFM_RES_MASK and all the unneeded logic that propagates these flags around.

crypto: memzero_explicit - make sure to clear out sensitive data Recently, in commit 13aa93c70e71 ("random: add and use memzero_explicit() for clearing data"), we have found that GCC may optimize some memset() cases away when it detects a stack variable is not being used anymore and going out of scope. This can happen, for example, in cases when we are clearing out sensitive information such as keying material or any e.g. intermediate results from crypto computations, etc. With the help of Coccinelle, we can figure out and fix such occurences in the crypto subsytem as well. Julia Lawall provided the following Coccinelle program: @@ type T; identifier x; @@ T x; ... when exists when any -memset +memzero_explicit (&x, -0, ...) ... when != x when strict @@ type T; identifier x; @@ T x[...]; ... when exists when any -memset +memzero_explicit (x, -0, ...) ... when != x when strict Therefore, make use of the drop-in replacement memzero_explicit() for exactly such cases instead of using memset().

crypto: cts - don't support empty messages My patches to make testmgr fuzz algorithms against their generic implementation detected that the arm64 implementations of "cts(cbc(aes))" handle empty messages differently from the cts template. Namely, the arm64 implementations forbids (with -EINVAL) all messages shorter than the block size, including the empty message; but the cts template permits empty messages as a special case. No user should be CTS-encrypting/decrypting empty messages, but we need to keep the behavior consistent. Unfortunately, as noted in the source of OpenSSL's CTS implementation [1], there's no common specification for CTS. This makes it somewhat debatable what the behavior should be. However, all CTS specifications seem to agree that messages shorter than the block size are not allowed, and OpenSSL follows this in both CTS conventions it implements. It would also simplify the user-visible semantics to have empty messages no longer be a special case. Therefore, make the cts template return -EINVAL on *all* messages shorter than the block size, including the empty message.

crypto: cts - don't support empty messages My patches to make testmgr fuzz algorithms against their generic implementation detected that the arm64 implementations of "cts(cbc(aes))" handle empty messages differently from the cts template. Namely, the arm64 implementations forbids (with -EINVAL) all messages shorter than the block size, including the empty message; but the cts template permits empty messages as a special case. No user should be CTS-encrypting/decrypting empty messages, but we need to keep the behavior consistent. Unfortunately, as noted in the source of OpenSSL's CTS implementation [1], there's no common specification for CTS. This makes it somewhat debatable what the behavior should be. However, all CTS specifications seem to agree that messages shorter than the block size are not allowed, and OpenSSL follows this in both CTS conventions it implements. It would also simplify the user-visible semantics to have empty messages no longer be a special case. Therefore, make the cts template return -EINVAL on *all* messages shorter than the block size, including the empty message.

crypto: algapi - use common mechanism for inheriting flags The flag CRYPTO_ALG_ASYNC is "inherited" in the sense that when a template is instantiated, the template will have CRYPTO_ALG_ASYNC set if any of the algorithms it uses has CRYPTO_ALG_ASYNC set. We'd like to add a second flag (CRYPTO_ALG_ALLOCATES_MEMORY) that gets "inherited" in the same way. This is difficult because the handling of CRYPTO_ALG_ASYNC is hardcoded everywhere. Address this by: - Add CRYPTO_ALG_INHERITED_FLAGS, which contains the set of flags that have these inheritance semantics. - Add crypto_algt_inherited_mask(), for use by template ->create() methods. It returns any of these flags that the user asked to be unset and thus must be passed in the 'mask' to crypto_grab_*(). - Also modify crypto_check_attr_type() to handle computing the 'mask' so that most templates can just use this. - Make crypto_grab_*() propagate these flags to the template instance being created so that templates don't have to do this themselves. Make crypto/simd.c propagate these flags too, since it "wraps" another algorithm, similar to a template.

crypto: cts - Convert to skcipher This patch converts cts over to the skcipher interface. It also optimises the implementation to use one CBC operation for all but the last block, which is then processed separately. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Revert "crypto: run initcalls for generic implementations earlier" This reverts commit c4741b23059794bd99beef0f700103b0d983b3fd. Crypto API self-tests no longer run at registration time and now occur either at late_initcall or upon the first use. Therefore the premise of the above commit no longer exists. Revert it and subsequent additions of subsys_initcall and arch_initcall. Note that lib/crypto calls will stay at subsys_initcall (or rather downgraded from arch_initcall) because they may need to occur before Crypto API registration.

crypto: include crypto- module prefix in template This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
