For the API EfiShellOpenRootByHandle():
The return status of the call to SimpleFileSystem->OpenVolume should be
checked.
It is possible that there is a media change in the device (like CD/DVD
ROM). In such case, the volume root opened and/or the device path opened
previously (also within EfiShellOpenRootByHandle) may be invalid.
This commit adds a check for the result of OpenVolume before subsequently
calling functions like EfiShellGetMapFromDevicePath() &
ConvertEfiFileProtocolToShellHandle().

than size of "Buffer", heap memory overflow occurs during copy.
One solution is to allocate pool first then copy the necessary bytes to new

Commit bd3fc8133b ("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 bd3fc8133b 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.

The "SPLIT_LIST.SplitStdOut" and "SPLIT_LIST.SplitStdIn" members currently
have type (SHELL_FILE_HANDLE *). This is wrong; SHELL_FILE_HANDLE is
already a pointer, there's no need to store a pointer to a pointer.
The error is obvious if we check where and how these members are used:
- In the RunSplitCommand() function, these members are used (populated)
extensively; this function has to be updated in sync.
ConvertEfiFileProtocolToShellHandle() already returns the temporary
memory file created with CreateFileInterfaceMem() as SHELL_FILE_HANDLE,
not as (SHELL_FILE_HANDLE *).
- In particular, the ConvertShellHandleToEfiFileProtocol() calls need to
be dropped as well in RunSplitCommand(), since
EFI_SHELL_PROTOCOL.SetFilePosition() and EFI_SHELL_PROTOCOL.CloseFile()
take SHELL_FILE_HANDLE parameters, not (EFI_FILE_PROTOCOL *).
Given that ConvertShellHandleToEfiFileProtocol() only performs a
type-cast (it does not adjust any pointer values), *and*
SHELL_FILE_HANDLE -- taken by EFI_SHELL_PROTOCOL member functions -- is
actually a typedef to (VOID *) -- see more on this later --, this
conversion error hasn't been caught by compilers.
- In the ProcessNewSplitCommandLine() function, RunSplitCommand() is
called either initially (passing in NULL / NULL; no update needed), or
recursively (passing in Split->SplitStdIn / Split->SplitStdOut; again no
update is necessary beyond the RunSplitCommand() modification above).
- In the UpdateStdInStdOutStdErr() and RestoreStdInStdOutStdErr()
functions, said structure members are compared and assigned to
"EFI_SHELL_PARAMETERS_PROTOCOL.StdIn" and
"EFI_SHELL_PARAMETERS_PROTOCOL.StdOut", both of which have type
SHELL_FILE_HANDLE, *not* (SHELL_FILE_HANDLE *).
The compiler hasn't caught this error because of the fatally flawed type
definition of SHELL_FILE_HANDLE, namely
typedef VOID *SHELL_FILE_HANDLE;
Pointer-to-void silently converts to and from most other pointer types;
among them, pointer-to-pointer-to-void. That is also why no update is
necessary for UpdateStdInStdOutStdErr() and RestoreStdInStdOutStdErr()
in this fix.
(
Generally speaking, using (VOID *) typedefs for opaque handles is a tragic
mistake in all of the UEFI-related specifications; this practice defeats
any type checking that compilers might help programmers with. The right
way to define an opaque handle is as follows:
//
// Introduce the incomplete structure type, and the derived pointer
// type, in both the specification and the public edk2 headers. Note
// that the derived pointer type itself is a complete type, and it can
// be used freely by client code.
//
typedef struct SHELL_FILE *SHELL_FILE_HANDLE;
//
// Complete the structure type in the edk2 internal C source files.
//
struct SHELL_FILE {
//
// list fields
//
};
This way the structure size and members remain hidden from client code,
but the C compiler can nonetheless catch any invalid conversions between
incompatible XXX_HANDLE types.

For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):
"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."
In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.
Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:
UINT8 *Ptr1, *Ptr2;
UINTN PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);
The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:
PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;

The ProcessCommandLine() function in the shell

Shell Parameters Protocol to assemble a new command
line, but the double quotes that may have been
originally present for an argument are not preserved.
ProcessCommandLine() is updated to check if an
