The PowerPC implementation of SHA-1 doesn't actually use the 16-word temporary array that's passed to the assembly code. This was probably meant to correspond to the 'W' array that lib/sha1.c uses. However, in sha1-powerpc-asm.S these values are actually stored in GPRs 16-31. Referencing SHA_WORKSPACE_WORDS from this code also isn't appropriate, since it's an implementation detail of lib/sha1.c. Therefore, just remove this unneeded array. Tested with: export ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- make mpc85xx_defconfig cat >> .config << EOF # CONFIG_MODULES is not set # CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set CONFIG_DEBUG_KERNEL=y CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y CONFIG_CRYPTO_SHA1_PPC=y EOF make olddefconfig make -j32 qemu-system-ppc -M mpc8544ds -cpu e500 -nographic \ -kernel arch/powerpc/boot/zImage \ -append "cryptomgr.fuzz_iterations=1000 cryptomgr.panic_on_fail=1" Cc: linuxppc-dev@lists.ozlabs.org Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Eric Biggers <ebiggers@google.com> Acked-by: Michael Ellerman <mpe@ellerman.id.au> (powerpc) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
