From 538c0f2d3798261161a28a05e445d0c85af56276 Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Fri, 3 Sep 2021 10:55:52 +0900 Subject: efi_loader: fix efi_tcg2_hash_log_extend_event() parameter check TCG EFI Protocol Specification defines that PCRIndex parameter passed from caller must be 0 to 23. TPM2_MAX_PCRS is currently used to check the range of PCRIndex, but TPM2_MAX_PCRS is tpm2 device dependent and may have larger value. This commit newly adds EFI_TCG2_MAX_PCR_INDEX macro, it is used to check the range of PCRIndex parameter.
