* MdePkg/BasePeCoffLib: Deal with broken debug directoriesArd Biesheuvel2023-05-051-0/+15
| | | | | | | | | | | | | | | | | | | | | | | Older versions of GenFw put the wrong value in the debug directory size field in the PE/COFF header: instead of putting the combined size of all the entries, it puts the size of the only entry it creates, but adds the size of the NB10 payload that the entry points to. This confuses the loader now that we started using additional debug directory entries to describe DLL characteristics. GenFw was fixed in commit 60e85a39fe49071, but the binaries that were generated with it still need to be supported. So let's detect this condition, and check whether the size of the debug directory is consistent with the NB10 payload: if we should expect additional directory entries where we observe the NB10 payload, the size field is clearly wrong, and we can break from the loop.

* MdePkg/BaseLib AARCH64: Make LongJump() BTI compatibleArd Biesheuvel2023-03-301-2/+1
| | | | | | | | | | | | | | | | | | Currently, the AArch64 implementation of LongJump() avoids using the RET instruction to perform the jump, even though the target address is held in the link register X30, as the nature of a long jump implies that the ordinary return address prediction machinery will not be able to make a correct prediction. However, LongJump() is rarely used, and the return stack will be out of sync in any case, so this optimization has little value in practice, and given that indirect calls other than function returns require a BTI landing pad at the call site, this optimization is not compatible with BTI. So let's just use RET instead. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Leif Lindholm <quic_llindhol@quicinc.com> Reviewed-by: Oliver Smith-Denny <osd@smith-denny.com>

Add UefiDevicePathLibStandaloneMm.inf back, but add comments that it is deprecated and that UefiDevicePathLibBase.inf should be used instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | REF? https://bugzilla.tianocore.org/show_bug.cgi?id=3912 UefiCpuPkg define a new Protocol with the new services SmmWaitForAllProcessor(), which can be used by SMI handler to optionally wait for other APs to complete SMM rendezvous in relaxed AP mode. VariableSmm and VariableStandaloneMM driver in MdeModulePkg need to use this services but MdeModulePkg can't depend on UefiCpuPkg. Thus, the solution is moving SmmCpuRendezvouslib.h from UefiCpuPkg to MdePkg and creating SmmCpuRendezvousLib NullLib version implementation in MdePkg as dependency for the pkg that can't depend on UefiCpuPkg.

* MdePkg: Probe Cc guest in BaseIoLibIntrinsicSevMin Xu2022-04-192-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902 Bad IO performance in SEC phase is observed after TDX features was introduced. (after commit b6b2de884864 - "MdePkg: Support mmio for Tdx guest in BaseIoLibIntrinsic"). This is because IsTdxGuest() will be called in each MMIO operation. It is trying to cache the result of the probe in the efi data segment. However, that doesn't work in SEC, because the data segment is read only (so the write seems to succeed but a read will always return the original value), leading to us calling TdIsEnabled() check for every mmio we do, which is causing the slowdown because it's very expensive. This patch is to call CcProbe instead of TdIsEnabled in IsTdxGuest. Null instance of CcProbe always returns CCGuestTypeNonEncrypted. Its OvmfPkg version returns the guest type in Ovmf work area.

If the access to MMIO fails, it fall backs to the direct access. BaseIoLibIntrinsic.inf is the IoLib used by other packages. It will not support I/O in Td guest. But some files are shared between BaseIoLibIntrinsic and BaseIoLibIntrinsicSev (IoLib.c is the example). So IoLibInternalTdxNull.c (which holds the null stub of the Td I/O routines) is included in BaseIoLibIntrinsic.inf. BaseIoLibIntrinsic.inf doesn't import TdxLib so that the Pkgs which include BaseIoLibIntrinsic.inf need not include TdxLib.
