pacify lint

add now required includes for memcpy prototypes analogue to other hash functions

(fix the build)

Fix byte order bug in murmurhash and pacify sanitizers.

murmurhash2: add an optimised path for the aligned pointer case.

RUMP fix: ifdef weak alias. Pointed out by martin@.

branches: 1.4.2; 1.4.4;
Fix kernel compilation: no namespace.h
Fix libc RCSID protection.
Remove useless cast.

Add weak symbol for murmurhash2.

Shut up lint.

Add MurmurHash2 -- a non-cryptographic hash function by Austin Appleby.
The code is taken from the upstream and is in the public domain.

Sort includes.

On big endian machines needs to include sys/endian.h for le32dec

Mainly affects cross builds on big endian; tested on FreeBSD mips
and Linux ppc.

Don't define weak aliases if _STANDALONE.

For all files under src/common, as well as related man pages under
src/lib/libc, or related headers under src/sys/sys: change u_intNN_t to
uintNN_t.

branches: 1.3.4; 1.3.8;
Fix SIGBUS issues on strict alignment issues. Use le32dec in RMD160
as the data pointer to RMD160_Update doesn't have to be aligned.
In SHA256_Update and SHA512_Update, only operate directly on the passed
in data if no left-over in the context exists and the data is correctly
aligned. The problem was exposed by the audit-packages rewrite in C
and reported for the libnbcompat version in PR pkg/36662.

branches: 1.2.2; 1.2.4; 1.2.12;
Add include of <sys/param.h>, to allow vax kernels to build again.
For vax, this causes <machine/macros.h> to be included and the
redefine of memset() to take effect.

this is shared with the kernel now.

Use defined constant instead of direct value (Etienne Brateau)

branches: 1.6.48;
Improve portability and clarity by using uint8_t for the byte data
and expanding u_int to not depend on the !POSIX types.

Don't define weak aliases if _STANDALONE.

ansify function definitions

branches: 1.3.12;
For all files under src/common, as well as related man pages under

restruct the include files to look like the other hash functions.

add files I forgot to commit.

move local decls to headers

Fix build with -Werror=array-parameter (Etienne Brateau)

branches: 1.24.28;
no need for the local defs of he enc functions; compat_defs.h provides them.

Use be{32,64}enc, suggested by joerg.

PR/47908: Gary Grebus: SHA256_Transform and SHA512_Transform are called
by openssl with unaligned buffers. All other Transforms can handle unaligned
buffers so make these handle them too.
XXX[1]: any better fixes are welcome
XXX[2]: pullup-5, pullup-6

Fix unaligned access in *_Final for SHA224/SHA256/SHA384.
Remaining part of PR 42273. Tested by snj.

Fix unaligned access as reported in PR port-sparc/42273

Don't define weak aliases if _STANDALONE.

Fix initialisation of SHA224.

- move #include <sys/param.h> inside #if defined(_KERNEL) section
where it's actually required
- add XXX comments that notes <sys/param.h> is required for vax memset(9)

Back out the addition of memset.c to the vax libkern, and instead do
as tsutsui@ suggested, and include <sys/param.h> in sha2.c instead.
On the vax, this causes <machine/macros.h> to be included, and it contains
that machine's memset() macro+inline.

Fix copy&paste errors

Provide fallback definitions of be[32|64]toh and htobe[32|64] for
systems without sys/endian.h.

use memcpy for bitcount writes to the buffer to avoid type punning issues.

- fix sha224 functions that used sha256 ctx, and add casts.
- fix sha224 function lengths.
- wrap long lines
- use NULL
- fix whitespace
- put all 224 functions together in the same spirit as 384

KNF

De-uglify:
- drop useless asserts
- use uintXX_t directly
- use NULL

Simplify by using sys/endian.h functions. Fixes Big Endian case for SHA2.

Add SHA224 implementation to libc.
Make libcrypto use the SHA2 implementation of libc.
Bump minor versions of libc and libcrypto.

C99 is no longer "very recent". Adjust a comment accordingly, and
start using uintNN_t instead of u_intNN_t in the definitions of
sha2_{byte,word32,word64}.
