Mike Turner 5dbfa01e2e MdePkg/BaseLib: Introduce CharToUpper and AsciiCharToUpper publicly
Introduce two public functions CharToUpper and AsciiCharToUpper.
They have the same functions as InternalCharToUpper and
InternalBaseLibAsciiToUpper.Considering the internal functions will
be removed,so directly I change their function names to the public ones'.

Hao Wu 0dab57708d MdePkg/BaseLib: AsciiStrToUnicodeStr(S) not handle EASCII properly
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1262

Current implementation of BaseLib APIs:

AsciiStrToUnicodeStr()
AsciiStrToUnicodeStrS()
AsciiStrnToUnicodeStrS()

do not handle EASCII properly.

More specifically, if the value of ASCII character is larger than 0x7F,
then the converted Unicode character will have all '1's in the higher 8
bits.

An example:
  0xC9 => 0xFFC9 (current implementations)
and it should be:
  0xC9 => 0x00C9

This commit will address this issue.

Ruiyu Ni 56658c22a6 MdePkg/SafeString: Fix potential out-of-bound memory access
Today's implementation of [Ascii]StrnCpyS/[Ascii]StrnCatS calls
StrnLenS () to get the length of source string but supplies the
destination buffer size as max size.
It's a bug that may cause out-of-bound memory access.
For example:
  StrnCpyS (Dest[10], 10, "hello", 6)
  -> StrnLenS ("hello", 10) //< cause out-of bound memory access

In a pool guard enabled environment, when using shell to edit an
existing file which contains empty line, the page fault is met.

The patch fixes the four library functions to avoid such
out-of-bound memory access.

Hao Wu 02263214ef MdePkg/BaseLib: Add safe string functions [U|A]StrnTo[A|U]StrS
Add the following 2 APIs:
UnicodeStrnToAsciiStrS
AsciiStrnToUnicodeStrS

These APIs are used to enhance APIs UnicodeStrToAsciiStrS and
AsciiStrToUnicodeStrS (without 'n' in names) by:
1. Adds an input parameter 'Length' to specify the maximum number of
Ascii/Unicode characters to convert.
2. Adds an output parameter 'DestinationLength' to indicate the number of
Ascii/Unicode characters successfully converted.

Hao Wu d8af3301a6 MdePkg/BaseLib: Add safe string functions that convert str to value
Add the following 8 APIs:
[Ascii]StrDecimalToUintnS
[Ascii]StrDecimalToUint64S
[Ascii]StrHexToUintnS
[Ascii]StrHexToUint64S

These safe version APIs are used to enhance their counterpart (APIs
without trailing 'S' in function names).

These safe version APIs perform checks to the input string and will return
relative status to reflect the check result:
When the input string exceeds the range of UINTN/64, these APIs will
return RETURN_UNSUPPORTED and store MAX_UINTN/64 in the output data.
When no conversion can be performed for the input string, these APIs will
return RETURN_SUCCESS and store 0 in the output data.

The optional parameter 'EndPointer', if provided, will point to the
character that stopped the scan.

Leif Lindholm 2ad9cf37a4 MdePkg: ensure SafeString length functions don't access beyond MaxSize
The StrnLenS and AsciiStrnLenS functions, when presented with a string
with no terminating NULL in the first MaxSize characters will check
the character at String[MaxSize] before checking if Length < MaxSize.
(They return the correct value, but have accessed beyond the stated
limit in the process.)

Flip the order of the tests to prevent this behaviour.
