The open coded access to co-processor #10 to set FPEXC is not supported by the CLANG assembler, but the architecturally correct VMSR instruction is not supported by older binutils. So keep the former unless __clang__ is defined.

Commit bd3fc81 ("ShellPkg/App: Fix memory leak and save resources.", 2016-05-20) added a FreePool() call for Split->SplitStdIn, near end of the RunSplitCommand(), right after the same shell file was closed with CloseFile(). The argument was: > 1) RunSplitCommand() allocates the initial SplitStdOut via > CreateFileInterfaceMem(). Free SplitStdIn after the swap to fix > the memory leak. There is no memory leak actually, and the FreePool() call in question constitutes a double-free: (a) This is how the handle is established: ConvertEfiFileProtocolToShellHandle ( CreateFileInterfaceMem (Unicode), NULL ); CreateFileInterfaceMem() allocates an EFI_FILE_PROTOCOL_MEM object and populates it fully. ConvertEfiFileProtocolToShellHandle() allocates some administrative structures and links the EFI_FILE_PROTOCOL_MEM object into "mFileHandleList". (b) EFI_SHELL_PROTOCOL.CloseFile() is required to close the SHELL_FILE_HANDLE and to release all associated data. Accordingly, near the end of RunSplitCommand(), we have: EfiShellClose() ShellFileHandleRemove() // // undoes the effects of ConvertEfiFileProtocolToShellHandle() // ConvertShellHandleToEfiFileProtocol() // // note that this does not adjust the pointer value; it's a pure // type cast // FileHandleClose() FileInterfaceMemClose() // // tears down EFI_FILE_PROTOCOL_MEM completely, undoing the // effects of CreateFileInterfaceMem () // The FreePool() call added by bd3fc81 conflicts with SHELL_FREE_NON_NULL(This); in FileInterfaceMemClose(), so remove it. This error can be reproduced for example with: > Shell> map | more > 'more' is not recognized as an internal or external command, operable > program, or script file. which triggers: > ASSERT MdeModulePkg/Core/Dxe/Mem/Pool.c(624): CR has Bad Signature with the following stack dump: > #0 0x000000007f6dc094 in CpuDeadLoop () at > MdePkg/Library/BaseLib/CpuDeadLoop.c:37 > #1 0x000000007f6dd1b4 in DebugAssert (FileName=0x7f6ed9f0 > "MdeModulePkg/Core/Dxe/Mem/Pool.c", LineNumber=624, > Description=0x7f6ed9d8 "CR has Bad Signature") at > OvmfPkg/Library/PlatformDebugLibIoPort/DebugLib.c:153 > #2 0x000000007f6d075d in CoreFreePoolI (Buffer=0x7e232c98, > PoolType=0x7f6bc1c4) at MdeModulePkg/Core/Dxe/Mem/Pool.c:624 > tianocore#3 0x000000007f6d060e in CoreInternalFreePool (Buffer=0x7e232c98, > PoolType=0x7f6bc1c4) at MdeModulePkg/Core/Dxe/Mem/Pool.c:529 > tianocore#4 0x000000007f6d0648 in CoreFreePool (Buffer=0x7e232c98) at > MdeModulePkg/Core/Dxe/Mem/Pool.c:552 > tianocore#5 0x000000007d49fbf8 in FreePool (Buffer=0x7e232c98) at > MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c:818 > tianocore#6 0x000000007d4875c3 in RunSplitCommand (CmdLine=0x7d898398, > StdIn=0x0, StdOut=0x0) at ShellPkg/Application/Shell/Shell.c:1813 > tianocore#7 0x000000007d487d59 in ProcessNewSplitCommandLine > (CmdLine=0x7d898398) at ShellPkg/Application/Shell/Shell.c:2121 > tianocore#8 0x000000007d488937 in RunShellCommand (CmdLine=0x7e233018, > CommandStatus=0x0) at ShellPkg/Application/Shell/Shell.c:2670 > tianocore#9 0x000000007d488b0b in RunCommand (CmdLine=0x7e233018) at > ShellPkg/Application/Shell/Shell.c:2732 > tianocore#10 0x000000007d4867c8 in DoShellPrompt () at > ShellPkg/Application/Shell/Shell.c:1349 > tianocore#11 0x000000007d48524d in UefiMain (ImageHandle=0x7e24c898, > SystemTable=0x7f5b6018) at ShellPkg/Application/Shell/Shell.c:631 Cc: Jaben Carsey <[email protected]> Cc: Marvin Häuser <[email protected]> Cc: Qiu Shumin <[email protected]> Cc: Ruiyu Ni <[email protected]> Fixes: bd3fc81 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <[email protected]>

This patch does not impact functionality. It aims to clarify the synchronization flow between the BSP and APs to enhance code readability and understanding: Steps tianocore#6 and tianocore#11 are the basic synchronization requirements for all cases. Steps tianocore#1 and tianocore#2 are additional requirements if the MmCpuSyncModeTradition mode is selected. Steps tianocore#1, tianocore#2, tianocore#3, tianocore#4, tianocore#5, tianocore#7, tianocore#8, tianocore#9, and tianocore#10 are additional requirements if the system needs to configure the MTRR. Steps tianocore#9 and tianocore#10 are additional requirements if the system needs to support the mSmmDebugAgentSupport. Signed-off-by: Jiaxin Wu <[email protected]>
