https://git.lua4.win/openbsd/atom?h=libressl-v4.1.22024-03-28T01:49:29+00:00Use C functions for RC4 public API.2024-03-28T01:49:29+00:00jsing2024-03-28T01:49:29+00:00urn:sha1:ee4f7c5caf1aa306d0a5b443f5c9133ae646925b
Rather than having public API switch between C and assembly, always
use C functions as entry points, which then call an assembly
implementation (if available). This makes it significantly easier
to deal with symbol aliasing/namespaces and it also means we
benefit from vulnerability prevention provided by the C compiler.
Rename the assembly generated functions from RC4() to rc4_internal()
and RC4_set_key() to rc4_set_key_internal(). Always include rc4.c
and change it to use defines that are similar to those used in BN.

Remove unused rc4 parisc assembly.2024-03-27T12:59:12+00:00jsing2024-03-27T12:59:12+00:00urn:sha1:ddf23e9f98c2df931e1bb028e49b3087001d98cc
This is already disabled since it is "about 35% slower than C code".
Remove assembly for stitched modes.2024-03-27T12:42:30+00:00jsing2024-03-27T12:42:30+00:00urn:sha1:f2c1de8d1431b110f243d6333f47359ef369d280
The stitched modes have been removed, so having assembly for them is of
little use.
Replace uses of endbr64 with _CET_ENDBR from cet.h2024-02-24T15:30:14+00:00tb2024-02-24T15:30:14+00:00urn:sha1:c730c3b3b1845cc7c4a4aceff2031f1135faa6bb
cet.h is needed for other platforms to emit the relevant .gnu.properties
sections that are necessary for them to enable IBT. It also avoids issues
with older toolchains on macOS that explode on encountering endbr64.

Various, ancient ciphers exposed some of their innards via an _options()
API. Apart from openssl version/speed, only some lua thingie in nmap ever
looked at these. Go figure.

Use explicit .text instead of .previous to please Windows/MinGW on amd642023-02-23T08:55:44+00:00tb2023-02-23T08:55:44+00:00urn:sha1:0dadd2bf46f37ca96a50e247649a11b3c5273234

Use .section .rodata instead of a plain .rodata2023-02-09T19:57:00+00:00tb2023-02-09T19:57:00+00:00urn:sha1:4355eb6aeababf0126972f85bdeed63048a99df1
At least gcc 12 on Fedora is very unhappy about a plain .rodata and throws
Error: unknown pseudo-op: `.rodata'. So add a .section in front of it to
make it happy.
