2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result. Then doing the same thing for BIOS_WARN with 's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi' Signed-off-by: Julius Werner <jwerner@chromium.org> Change-Id: I3d0573acb23d2df53db6813cb1a5fc31b5357db8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/61309 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Reviewed-by: Lance Zhao Reviewed-by: Jason Glenesk <jason.glenesk@gmail.com>

2020-05-08security: tcg-2.0: Ignore data payload for errors, fix Cr50 boot modeJulius Werner
This patch improves the response buffer handling for TPM 2.0. Previously we would allow any command to return no payload, but if there was a payload we would always try to unmarshal it according to the normal success response. This was sort of relying on the fact that the TPM usually returns no additional data after the header for error responses, but in practice that is not always true. It also means that commands without a response payload accidentally work by default even though we did not explicitly add unmarshallig support for them, which seems undesirable. Adding explicit unmarshalling support for TPM2_SelfTest which was only supported through this loophole before. This patch changes the behavior to always accept any amount of payload data for error responses but not unmarshal any of it. None of our use cases actually care about payload data for errors, so it seems safer to not even try to interpret it. For success responses, on the other hand, we always require support for the command to be explicitly added. This fixes a problem with the Cr50 GET_BOOT_MODE command where an error response would only return the subcommand code but no data after that. Also add support for a second, slightly different NO_SUCH_COMMAND error code that was added in Cr50 recently.

This reverts commit fdb9805d6884090fd7bf62dbdf9c858692e55fb4. CB:33252 wasn't reviewed by a TPM maintainer and breaks abstraction layers (pulling TSS-details into TSPI, completely changing interpretation of the arguments to tlcl_extend() based on TSS version). It's also not clear why it was implemented the way it was (should have been much easier and cleaner ways to achieve the same thing). Since the author is not reacting, let's revert it for now. It can be cleaned up and resubmitted later. (Not reverting the header changes since those are not objectionable, and there are later patches dependent on it.)
