This results in uncertainty on what exactly is the current UID used for machine_set_hashable and to compare against with TLV. Add an additional global var, that represents a binary representation of the soc_uid_bin variable. This can now be used to feed as data for bound-soc-uid into `bareboxtlv-generator.py` or as the value for `CONFIG_HABV4_CSF_UNLOCK_UID` Signed-off-by: Fabian Pflug --- common/misc.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/common/misc.c b/common/misc.c index ecf9574f7a..f18c8b5825 100644 --- a/common/misc.c +++ b/common/misc.c @@ -268,6 +268,7 @@ const uuid_t *barebox_get_product_uuid(void) BAREBOX_MAGICVAR(global.product.uuid, "SMBIOS-reported product UUID"); static char *soc_uid_str; +static char *soc_uid_bin_str; static void *soc_uid; static size_t soc_uid_len; @@ -295,16 +296,19 @@ void barebox_set_soc_uid(const char *uidstr, const void *uidbuf, size_t len) soc_uid = xmemdup(uidbuf, len); soc_uid_len = len; + soc_uid_bin_str = xzalloc(len * 2 + 1); + bin2hex(soc_uid_bin_str, uidbuf, len); + if (uidstr) { soc_uid_str = xstrdup(uidstr); } else { - soc_uid_str = xzalloc(len * 2 + 1); - bin2hex(soc_uid_str, uidbuf, len); + soc_uid_str = soc_uid_bin_str; } machine_id_set_hashable(uidbuf, len); globalvar_add_simple_string("soc_uid", &soc_uid_str); + globalvar_add_simple_string("soc_uid_bin", &soc_uid_bin_str); } BAREBOX_MAGICVAR(global.soc_uid, "SoC Unique ID"); -- 2.47.3
