2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers1-1/+2
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.

2020-08-28crypto: ccree - fix runtime PM imbalance on errordinghao.liu@zju.edu.cn1-1/+5
pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. However, users of cc_pm_get(), a direct wrapper of pm_runtime_get_sync(), assume that PM usage counter will not change on error. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.

2020-08-07mm, treewide: rename kzfree() to kfree_sensitive()Waiman Long5-12/+12
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.

2020-02-22crypto: ccree - simplify Runtime PM handlingGeert Uytterhoeven4-65/+29
Currently, a large part of the probe function runs before Runtime PM is enabled. As the driver manages the device's clock manually, this may work fine on some systems, but may break on platforms with a more complex power hierarchy. Fix this by moving the initialization of Runtime PM before the first register access (in cc_wait_for_reset_completion()), and putting the device to sleep only after the last access (in cc_set_ree_fips_status()). This allows to remove the pm_on flag, which was used to track manually if Runtime PM had been enabled or not. Remove the cc_pm_{init,go,fini}() wrappers, as they are called only once, and obscure operation.
