* vboot/secdata: fix 2secdata.h includesJoel Kitching2019-08-312-4/+1
| | | | | | | | | | | | | | | | | | | | Get rid of vb2_context forward declaration and vb2_error_t redefinition from 2secdata.h, and properly include 2api.h instead. Remove 2secdata.h from 2api.h (should not be publicly accessible), and add 2secdata.h include to appropriate files.

| | | | | | | | | | | | | | | | | | | | | | | For clarity's sake, rename: secdata -> secdata_firmware secdatak -> secdata_kernel secdata is now the general term to refer to any secure data spaces: firmware, kernel, and FWMP. Once coreboot code has been updated, the sections in 2api.h and 2constants.h may be removed.

* Fix fall through warning reported by ToT clang.Manoj Gupta2019-08-281-0/+21
| | | | | | | | | | | | | | | | | | | | Clang is diagnosing implicit fallthrough in C code past https://reviews.llvm.org/rL369414. Detect the support for the fallthrough attributes in gcc/clang and enable it as VBOOT_FALLTHROUGH (copied from boringssl). This is needed to fix ToT clang builds. Note: GCC apparently does not diagnose fallthrough to another case with break but clang does (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91432). And clang does not detect the fallthrough based on code comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | vb2_shared_data struct has many offsets to other objects in the workbuf. They are all prefixed with `workbuf_`, e.g.: uint32_t workbuf_data_key_offset; uint32_t workbuf_data_key_size; In order to adhere to a hierarchical structure on the workbuf, remove the workbuf_ prefix from these symbols to reflect the relationship between vb2_shared_data and its children more accurately. Create a helper function vb2_member_of to safely look up a child of a particular object in the workbuf by offset. Pointer arithmetic to find vb2_shared_data children is replaced with calls to this function.

Enabling it in the vboot Makefile means they also apply to host utilities and tests, which sounds desirable for consistency. Fix enough of the cruft and bad coding practices that accumulated over the years of not having warnings enabled to get it to build again (this includes making functions static, removing dead code, cleaning up prototypes, etc.).

* futility: Merge Debug() into VB2_DEBUG()Julius Werner2019-03-062-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Futility has two debug facilities: the Debug() function that can be enabled by passing --debug on the command line, and the VB2_DEBUG() macro (mostly in common code from the firmware/ directory that it includes) which can only be enabled by passing DEBUG=1 at build time. This is confusing and inconvenient, since you don't always want to rebuild futility whenever you need that extra debug output and it's not very obvious that you can get even more debugging beyond just passing --debug. This patch resolves the inconsistency by merging both facilities together into a single VB2_DEBUG() that is output when passing --debug. In order to make this work, we'll have to move the VBOOT_DEBUG #define so that it only affects the stub implementation of vb2ex_printf(), and any caller overriding the stub is in charge of their own destiny. This should be okay since callers can still individually implement debugging policy in their versions of vb2ex_printf() if they want to. (This may have been useful to cut down the binary space for debugging strings, but our firmware has always been unconditionally enabling VBOOT_DEBUG in the past years, so that doesn't seem to be very important in practice.)
