2023-09-20crypto: cavium/nitrox - refactor deprecated strncpyJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We know `hw.partname` is supposed to be NUL-terminated by its later use with seq_printf: | nitrox_debugfs.c +25 | seq_printf(s, " Part Name: %s\n", ndev->hw.partname); Let's prefer a more robust and less ambiguous string interface. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer.

2023-01-06crypto: xts - drop xts_check_key()Vladis Dronov
xts_check_key() is obsoleted by xts_verify_key(). Over time XTS crypto drivers adopted the newer xts_verify_key() variant, but xts_check_key() is still used by a number of drivers. Switch drivers to use the newer xts_verify_key() and make a couple of cleanups. This allows us to drop xts_check_key() completely and avoid redundancy.

2022-10-21crypto: nitrox - avoid double free on error path in nitrox_sriov_init()Natalia Petrova
If alloc_workqueue() fails in nitrox_mbox_init() it deallocates ndev->iov.vfdev and returns error code, but then nitrox_sriov_init() calls nitrox_sriov_cleanup() where ndev->iov.vfdev is deallocated again. Fix this by nulling ndev->iov.vfdev after the first deallocation. Found by Linux Verification Center (linuxtesting.org) with SVACE. Fixes: 9e5de3e06e54 ("crypto: cavium/nitrox - Add mailbox...")

loop body When list_for_each_entry() completes the iteration over the whole list without breaking the loop, the iterator value will be a bogus pointer computed based on the head element. While it is safe to use the pointer to determine if it was computed based on the head element, either with list_entry_is_head() or &pos->member == head, using the iterator variable after the loop should be avoided. In preparation to limit the scope of a list iterator to the list traversal loop, use a dedicated pointer to point to the found element [1].

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-08-07mm, treewide: rename kzfree() to kfree_sensitive()Waiman Long
As said by Linus: A symmetric naming is only helpful if it implies symmetries in use. Otherwise it's actively misleading. In "kzalloc()", the z is meaningful and an important part of what the caller wants. In "kzfree()", the z is actively detrimental, because maybe in the future we really _might_ want to use that "memfill(0xdeadbeef)" or something. The "zero" part of the interface isn't even _relevant_. The main reason that kzfree() exists is to clear sensitive information that should not be leaked to other future users of the same memory objects. Rename kzfree() to kfree_sensitive() to follow the example of the recently added kvfree_sensitive() and make the intention of the API more explicit. In addition, memzero_explicit() is used to clear the memory to make sure that it won't get optimized away by the compiler. The renaming is done by using the command sequence: git grep -w --name-only kzfree |\ xargs sed -i 's/kzfree/kfree_sensitive/' followed by some editing of the kfree_sensitive() kerneldoc and adding a kzfree backward compatibility macro in slab.h.

2020-03-06crypto: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by: Gustavo A. R.

2020-01-09crypto: remove CRYPTO_TFM_RES_BAD_KEY_LENEric Biggers
The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to make the ->setkey() functions provide more information about errors. However, no one actually checks for this flag, which makes it pointless. Also, many algorithms fail to set this flag when given a bad length key. Reviewing just the generic implementations, this is the case for aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309, rfc7539, rfc7539esp, salsa20, seqiv, and xcbc. But there are probably many more in arch/*/crypto/ and drivers/crypto/. Some algorithms can even set this flag when the key is the correct length. For example, authenc and authencesn set it when the key payload is malformed in any way (not just a bad length), the atmel-sha and ccree drivers can set it if a memory allocation fails, and the chelsio driver sets it for bad auth tag lengths, not just bad key lengths. So even if someone actually wanted to start checking this flag (which seems unlikely, since it's been unused for a long time), there would be a lot of work needed to get it working correctly. But it would probably be much better to go back to the drawing board and just define 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 this flag.

2019-10-05crypto: cavium/nitrox - check assoclen and authsize for gcm(aes) cipherNagadheeraj Rottela
Check if device supports assoclen to solve hung task timeout error when extra tests are enabled. Return -EINVAL if assoclen is not supported. Check authsize to return -EINVAL if authentication tag size is invalid. Change blocksize to 1 to match with generic implementation.

2019-08-22crypto: des - split off DES library from generic DES cipher driverArd Biesheuvel
Another one for the cipher museum: split off DES core processing into a separate module so other drivers (mostly for crypto accelerators) can reuse the code without pulling in the generic DES cipher itself. This will also permit the cipher interface to be made private to the crypto API itself once we move the only user in the kernel (CIFS) to this library interface.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.
