From 5847084f6bbd0778afb29f0574085d4210ea8cff Mon Sep 17 00:00:00 2001 From: Vagrant Cascadian Date: Thu, 16 Jun 2016 12:28:40 -0700 Subject: Respect SOURCE_DATE_EPOCH when building FIT images. Embedding timestamps in FIT images results in unreproducible builds for targets that generate a fit image, such as dra7xx_evm. This patch uses the SOURCE_DATE_EPOCH environment variable, when set, to use specified value for the date. Thanks to HW42 for debugging the issue and providing the patch: https://lists.alioth.debian.org/pipermail/reproducible-builds/Week-of-Mon-20160606/005722.html For more information about reproducible builds and the SOURCE_DATE_EPOCH specification: https://reproducible-builds.org/specs/source-date-epoch/ https://reproducible-builds.org/ Signed-off-by: Vagrant Cascadian Reviewed-by: Simon Glass --- tools/default_image.c | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-) (limited to 'tools/default_image.c') diff --git a/tools/default_image.c b/tools/default_image.c index 3ed7014..6e4ae14 100644 --- a/tools/default_image.c +++ b/tools/default_image.c @@ -88,7 +88,6 @@ static void image_set_header(void *ptr, struct stat *sbuf, int ifd, struct image_tool_params *params) { uint32_t checksum; - char *source_date_epoch; time_t time; image_header_t * hdr = (image_header_t *)ptr; @@ -98,18 +97,7 @@ static void image_set_header(void *ptr, struct stat *sbuf, int ifd, sizeof(image_header_t)), sbuf->st_size - sizeof(image_header_t)); - source_date_epoch = getenv("SOURCE_DATE_EPOCH"); - if (source_date_epoch != NULL) { - time = (time_t) strtol(source_date_epoch, NULL, 10); - - if (gmtime(&time) == NULL) { - fprintf(stderr, "%s: SOURCE_DATE_EPOCH is not valid\n", - __func__); - time = 0; - } - } else { - time = sbuf->st_mtime; - } + time = imagetool_get_source_date(params, sbuf->st_mtime); /* Build new header */ image_set_magic(hdr, IH_MAGIC); -- cgit v1.1
