crypto: marvel/cesa - Fix tdma descriptor on 64-bit

2021-01-22T03:57:31+00:00

The patch that added src_dma/dst_dma to struct mv_cesa_tdma_desc
is broken on 64-bit systems as the size of the descriptor has been
changed.  This patch fixes it by using u32 instead of dma_addr_t.

crypto: marvell/octeontx - Use dma_set_mask_and_coherent to simplify code

2020-11-27T06:13:48+00:00

'pci_set_dma_mask()' + 'pci_set_consistent_dma_mask()' can be replaced by
an equivalent 'dma_set_mask_and_coherent()' which is much less verbose.

crypto: sha - split sha.h into sha1.h and sha2.h

2020-11-20T03:45:33+00:00

Currently  contains declarations for both SHA-1 and SHA-2,
and  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  into two headers  and
, 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.

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

crypto: marvell/cesa - Fix sparse warnings

2020-08-21T04:45:27+00:00

This patch fixes most sparse warnings in the cesa driver.  The only
ones remaining are to do with copying data between iomem pointers and
SG lists.

Most changes are trivial.  The following are the noteworthy ones:

- Removal of swab in mv_cesa_aes_setkey.  This appears to be bogus
as everything gets swabbed again later on so for BE this ends up
being different from LE.  The change takes the LE behaviour as the
correct one.

- next_dma in mv_cesa_tdma_chain was not swabbed.

crypto: algapi - Remove skbuff.h inclusion

2020-08-20T04:04:28+00:00

The header file algapi.h includes skbuff.h unnecessarily since
all we need is a forward declaration for struct sk_buff.  This
patch removes that inclusion.

Unfortunately skbuff.h pulls in a lot of things and drivers over
the years have come to rely on it so this patch adds a lot of
missing inclusions that result from this.

mm, treewide: rename kzfree() to kfree_sensitive()

2020-08-07T18:33:22+00:00

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.
