commit 8786841bc2020f7f2513a6c74e64912f07b9c0dc upstream.

Use the full path in the include guards for the BLAKE2s headers to avoid
ambiguity and to match the convention for most files in include/crypto/.

commit 66d7fb94e4ffe5acc589e0b2b4710aecc1f07a28 upstream.

The C implementation was originally based on Samuel Neves' public
domain reference implementation but has since been heavily modified
for the kernel. We're able to do compile-time optimizations by moving
some scaffolding around the final function into the header file.

<title>crypto: shash - avoid comparing pointers to exported functions under CFI</title>

<id>urn:sha1:80b9d3becd84ef0b096df286cdf4663d74e8354a</id>
<content type='text'>
[ Upstream commit 22ca9f4aaf431a9413dcc115dd590123307f274f ]

crypto_shash_alg_has_setkey() is implemented by testing whether the
.setkey() member of a struct shash_alg points to the default version,
called shash_no_setkey(). As crypto_shash_alg_has_setkey() is a static
inline, this requires shash_no_setkey() to be exported to modules.

Unfortunately, when building with CFI, function pointers are routed
via CFI stubs which are private to each module (or to the kernel proper)
and so this function pointer comparison may fail spuriously.

Let's fix this by turning crypto_shash_alg_has_setkey() into an out of
line function.

<title>crypto: algif_skcipher - Use chunksize instead of blocksize</title>

<content type='text'>
commit 5b0fe9552336338acb52756daf65dd7a4eeca73f upstream.

When algif_skcipher does a partial operation it always process data
that is a multiple of blocksize.  However, for algorithms such as
CTR this is wrong because even though it can process any number of
bytes overall, the partial block must come at the very end and not
in the middle.

This is exactly what chunksize is meant to describe so this patch
changes blocksize to chunksize.

<title>crypto: skcipher - add the ability to abort a skcipher walk</title>

<content type='text'>
After starting a skcipher walk, the only way to ensure that all
resources it has tied up are released is to complete it. In some
cases, it will be useful to be able to abort a walk cleanly after
it has started, so add this ability to the skcipher walk API.

<content type='text'>
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.

<title>crypto: des/3des_ede - add new helpers to verify keys</title>

<id>urn:sha1:6ee41e5420d0afa8cddf09aa7384dabe570f8dc7</id>
<content type='text'>
The recently added helper routine to perform key strength validation
of triple DES keys is slightly inadequate, since it comes in two versions,
neither of which are highly useful for anything other than skciphers (and
many drivers still use the older blkcipher interfaces).

So let's add a new helper and, considering that this is a helper function
that is only intended to be used by crypto code itself, put it in a new
des.h header under crypto/internal.

While at it, implement a similar helper for single DES, so that we can
start replacing the pattern of calling des_ekey() into a temp buffer
that occurs in many drivers in drivers/crypto.

<title>crypto: user - fix potential warnings in cryptouser.h</title>

<content type='text'>
Function definitions in headers are usually marked as 'static inline'.

Since 'inline' is missing for crypto_reportstat(), if it were not
referenced from a .c file that includes this header, it would produce
a warning.

Also, 'struct crypto_user_alg' is not declared in this header.

I included &lt;linux/crytouser.h&gt; instead of adding the forward declaration
as suggested [1].

Detected by compile-testing this header as a standalone unit:

./include/crypto/internal/cryptouser.h:6:44: warning: ‘struct crypto_user_alg’ declared inside parameter list will not be visible outside of this definition or declaration
 struct crypto_alg *crypto_alg_match(struct crypto_user_alg *p, int exact);
                                            ^~~~~~~~~~~~~~~
./include/crypto/internal/cryptouser.h:11:12: warning: ‘crypto_reportstat’ defined but not used [-Wunused-function]
 static int crypto_reportstat(struct sk_buff *in_skb, struct nlmsghdr *in_nlh, struct nlattr **attrs)

Currently, NETLINK_CRYPTO works only in the init network namespace. It
doesn't make much sense to cut it out of the other network namespaces,
so do the minor plumbing work necessary to make it work in any network
namespace. Code inspired by net/core/sock_diag.c.

Tested using kcapi-dgst from libkcapi [1]:
Before:
    # unshare -n kcapi-dgst -c sha256 &lt;/dev/null | wc -c
    libkcapi - Error: Netlink error: sendmsg failed
    libkcapi - Error: Netlink error: sendmsg failed
    libkcapi - Error: NETLINK_CRYPTO: cannot obtain cipher information for hmac(sha512) (is required crypto_user.c patch missing? see documentation)
    0

After:
    # unshare -n kcapi-dgst -c sha256 &lt;/dev/null | wc -c
    32
