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.

2022-09-30crypto: cavium - prevent integer overflow loading firmwareDan Carpenter
The "code_length" value comes from the firmware file. If your firmware is untrusted realistically there is probably very little you can do to protect yourself. Still we try to limit the damage as much as possible. Also Smatch marks any data read from the filesystem as untrusted and prints warnings if it not capped correctly.

2022-04-08crypto: cavium/nitrox - remove check of list iterator against head past the ↵Jakob Koschel
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].

On my renesas salavator-X, I saw some cavium driver failing crypto self-tests. But salvator does not have such hardware. This is due to cavium/zip driver registering algorithms even if hardware is not present. The solution is to move algorithm registration in the probe function.

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.
