# BusyBox Patches
2+
3+
This directory contains patches we apply during our various builds of BusyBox. They are not necessarily *all* applied to all builds, but they are intended to be as minimal as possible, focused primarily on compilation or correctness issues, such that we still represent upstream's releases accurately.
4+
5+
Metadata in each patch should be following [Debian's "DEP-3" Patch Tagging Guidelines](https://dep-team.pages.debian.net/deps/dep3/) to ensure we track appropriate provenance (and that they were submitted upstream in some form, or that we're explicitly tracking our justification for *why* we didn't do so).

Description: libbb/sha: add missing sha-NI guard
2+
Author: André Przywara <[email protected]>

Date: Tue, 10 Sep 2024 06:33:00 -0700

Origin: http://lists.busybox.net/pipermail/busybox/2024-September/090899.html

The ENABLE_SHA1_HWACCEL Kconfig symbol is meant to be archicture
7+
agnostic, so can be enabled regardless of whether your build
8+
architecture provides hardware acceleration or not. At the moment only
9+
x86 implements this, so every piece of optimised code should be guarded
10+
by both ENABLE_SHA1_HWACCEL and (__x86_64__ || __i386__). This is missing
11+
at one place, so compiling for arm64 breaks when ENABLE_SHA1_HWACCEL is
12+
enabled:
13+
================================
14+
libbb/hash_md5_sha.c: In function ‘sha1_end’:
15+
libbb/hash_md5_sha.c:1316:28: error: ‘sha1_process_block64_shaNI’ undeclared (first use in this function); did you mean ‘sha1_process_block64’?
16+
1316 | || ctx->process_block == sha1_process_block64_shaNI
17+
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
18+
| sha1_process_block64
19+
libbb/hash_md5_sha.c:1316:28: note: each undeclared identifier is reported only once for each function it appears in
20+
make[1]: *** [scripts/Makefile.build:197: libbb/hash_md5_sha.o] Error 1
21+
make: *** [Makefile:744: libbb] Error 2
22+
================================
23+
24+
Add the missing guards around the call to sha1_process_block64_shaNI to
25+
fix the build on other architectures with ENABLE_SHA1_HWACCEL enabled.
