2017-06-01	9d6fc3c Browse files » FWU: Introduce FWU_SMC_IMAGE_RESET ... This SMC is as a means for the image loading state machine to go from COPYING, COPIED or AUTHENTICATED states to RESET state. Previously, this was only done when the authentication of an image failed or when the execution of the image finished. Documentation updated.

	128daee Browse files » FWU: Check for overlaps when loading images ... Added checks to FWU_SMC_IMAGE_COPY to prevent loading data into a memory region where another image data is already loaded. Without this check, if two images are configured to be loaded in overlapping memory regions, one of them can be loaded and authenticated and the copy function is still able to load data from the second image on top of the first one. Since the first image is still in authenticated state, it can be executed, which could lead to the execution of unauthenticated arbitrary code of the second image. Firmware update documentation updated. Change-Id: Ib6871e569794c8e610a5ea59fe162ff5dcec526c Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com> Antonio Nino Diaz committed on 1 Jun 2017
	79eb1af Browse files » Remove `DISABLE_PEDANTIC` build option ... It doesn't make sense to use the `-pedantic` flag when building the Trusted Firmware as we use GNU extensions and so our code is not fully ISO C compliant. This flag only makes sense if the code intends to be ISO C compliant.

This options enables an implementation of SHA-256 that has a smaller code footprint (~1.6 KB less) but is also ~30% slower.

Added a small note about this option to the documentation of the authentication framework.

This subset internally uses `snprintf`, but the only format specifier used is '%d', which is supported by `tf_snprintf`. This patch makes mbed TLS use `tf_snprintf` instead of `snprintf`, saving 3 KB in both debug and release builds when TBBR is enabled.

	bb41eb7 Browse files » cert: move platform_oid.h to include/tools_share for all platforms ... Platforms aligned with TBBR are supposed to use their own OIDs, but defining the same macros with different OIDs does not provide any value (at least technically). For easier use of TBBR, this commit allows platforms to reuse the OIDs obtained by ARM Ltd. This will be useful for non-ARM vendors that do not need their own extension fields in their certificate files. The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by defining USE_TBBR_DEFS as 1. USE_TBBR_DEFS is 0 by default to keep the backward compatibility. For clarification, I inserted a blank line between headers from the include/ directory (#include <...>) and ones from a local directory (#include "..." ).

	2a6c1a8 Browse files » fip: move headers shared between TF and fiptool to include/tools_share ... Some header files need to be shared between TF and host programs. For fiptool, two headers are copied to the tools/fiptool directory, but it looks clumsy. This commit introduces a new directory, include/tools_share, which collects headers that should be shared between TF and host programs. This will clarify the interface exposed to host tools. We should add new headers to this directory only when we really need to do so.
