[PATCH v2 0/9] EmbeddedPkg: eliminate calls to deprecated functions

[PATCH v2 0/9] EmbeddedPkg: eliminate calls to deprecated functions

[Ard Biesheuvel]

This series prepares EmbeddedPkg for building with the preprocess symbol
DISABLE_NEW_DEPRECATED_INTERFACES defined, by adding missing components
to EmbeddedPkg (#3), fixing broken code or code that relies on deprecated
functionality (#1 - #2, #4 - #8), and finally adds
-DDISABLE_NEW_DEPRECATED_INTERFACES to the CC flags for all build types,
toolchains and architectures.

v2:
- incorporated Laszlo's feedback
- add some R-b's

Again, a *big* thank you to Laszlo for taking the time to review these
patches. I do apologize for not being as thorough as I could have been,
resulting in issues in the code that Laszlo spotted in his review.

[PATCH v2 1/9] EmbeddedPkg/AndroidFastbootTransportTcpDxe: remove broken hostname handling

[Ard Biesheuvel]

The fastboot TCP connection setup routine retrieves a hostname from a
UEFI variable 'hostname' that is scoped under a GUID gEfiHostnameVariableGuid
whose definition is missing from the code. Since the hostname is only printed
and then discarded, let's just drop the whole thing.

It also gets rid of some needlessly hardcoded buffers, which I'm all
for - so:

Remove this unused version: all existing platforms use the one under
ArmPlatformPkg instead.

[PATCH v2 4/9] EmbeddedPkg/GdbDebugAgent: fix VOID* cast of incorrect size

[Ard Biesheuvel]

The result of PcdGet64() can only be cast to VOID* on 64-bit platforms,
so add an intermediate UINTN cast to make this code build again on 32 bit.

I'll try to keep the bikeshedding to a minimum, but since
mNumDataBytes is generated from NumBytesString in the first place, why
not do
  "DATA%s", NumBytesString
?

Well, the original code used NumBytesString, and your updated version
does not.

As per Laszlo's comment - the implementation of
AsciiStrHexToUint64 means that an arbitrarily long string of leading
zeroes could be handled by this version that would not previously have
been handled.

If that is desired behaviour, then that makes this change a bugfix
rather than just an API cleanup. Which should be mentioned in the
commit message. If you do that:

Indeed, I missed that. Been looking at many different variations on
this theme over the past week, so my vision got a little blurry,

Yes, I agree it's an improvement if Ard spells out the "added
robustness" in the commit message. (Should not require a repost.)

In this case, we do have a comment in the function:

  // Argument is 8-character ASCII string hex representation of number
  // of bytes that will be sent in the data phase.
  // Response is "DATA" + that same 8-character string.

Honestly, I didn't trust it fully. I didn't verify where the data comes
from, so the comment could be true. But, in all such cases, as a general
principle, I re-format the string representation from the parsed integer
value. It deals nicely with leading "no-op" characters, such as space
and zeros, and it also drops any trailing garbage even if the input is
*not* overlong.

(For example, if the input is "12zzzz", then AsciiStrHexToUint64() will
return 0x12, and ignore the "zzzz" suffix. I think there's value in not
reproducing such trailing garbage.)

I guess I stick to this principle without much thinking, so I didn't ask
for the commit message to be updated. :)

... Extrapolating a bit, I think you might ask for a commit message
update on patch v2 #8 as well :) Because, in addition to the API
replacement there, the patch fixes a separate, genuine overflow as well
(present in the original code). I think mentioning that fact in passing
in the commit message of v2 #8 should suffice.

Thanks!
Laszlo
