From 629ed239a9d27f2b58697ef48d7a12c81e5d74cf Mon Sep 17 00:00:00 2001 From: Logan Chien Date: Thu, 31 Aug 2017 19:15:50 +0800 Subject: Fix import_scrypt.sh This commit fixes various issues in import_scrypt.sh: * Add `-N` option to `diff` command so that arm_neon.diff can be generated by import_scrypt.sh * Rename SCRYPT_PATCHES_bionic_SOURCES to SCRYPT_PATCHES_arm_neon_SOURCES * Reorder SCRYPT_PATCHES_arm_neon_SOURCES to mimic git-diff output * Add missing `lib/crypto/crypto_scrypt-sse.c` file for use_openssl_pbkdf2.patch * Add `-f` to `rm` command in the `generate` command because `config.h` is not in the upstream release tarball * Replace typo `$SCRYPT_DIR_ORIG_ORIG` with `$SCRYPT_DIR_ORIG` * Rename arm-neon.patch to arm_neon.patch (for consistency) Bug: 65425184 Test: ./import_scrypt.sh import upstream/scrypt-1.1.6.tgz Test: ./import_scrypt.sh generate patches/arm_neon.patch \ upstream/scrypt-1.1.6.tgz Test: ./import_scrypt.sh generate patches/use_openssl_pbkdf2.patch \ upstream/scrypt-1.1.6.tgz Change-Id: I843a21440527ed4037525468e9f66630f24b4cee --- import_scrypt.sh | 6 +- patches/README | 2 +- patches/arm-neon.patch | 436 ------------------------------------------------- patches/arm_neon.patch | 436 +++++++++++++++++++++++++++++++++++++++++++++++++ scrypt.config | 7 +- 5 files changed, 444 insertions(+), 443 deletions(-) delete mode 100644 patches/arm-neon.patch create mode 100644 patches/arm_neon.patch diff --git a/import_scrypt.sh b/import_scrypt.sh index 324eae6..d85d763 100755 --- a/import_scrypt.sh +++ b/import_scrypt.sh @@ -90,7 +90,7 @@ function main() { declare -r patch=$1 shift || usage "No patch file specified."
