Correctly define the read-only data sections with the
toolchain-specific section name. This hardens image permission
security and may save image space.

The current certificate lookup code does not check the bounds of the
authentication data before accessing it. Abort if the header cannot
fit, and proceed to the next hashing algortihm if the OID of the
current one exceeds the authentication data bounds.

Additionally move the two-byte encoding check out of the loop as the
data is invariant.

C prohibits not only dereferencing but also casting to unaligned
pointers. Thus, the current set of unaligned APIs cannot be called
safely. Update their prototypes to take VOID * pointers, which must
be able to represent any valid pointer.

The current certificate lookup code does not check the bounds of the
authentication data before accessing it. Abort if the header cannot
fit. Also, the lookup code aborts once the authetication data is
smaller than an algorithm's OID size. As OIDs are variably-sized,
this may cause unexpected authentication failure due to the early
error-exit.

Additionally move the two-byte encoding check out of the loop as the
data is invariant.

Different toolchains of the EDK II build system may generate ELF or
Mach-O files, which use the ".rodata" naming convention, or PE/COFF
files, which use the ".rdata" naming convention. Section permissions
are chosen based on this name per file format by NASM. To harden
image permission security, and to save space by avoiding both
".rdata" and ".rodata" sections being emitted, expose the appropriate
name as a preprocessor constant.

C prohibits not only dereferencing but also casting to unaligned
pointers. Thus, the current set of unaligned APIs cannot be called
safely. Update their prototypes to take VOID * pointers, which must
be able to represent any valid pointer.

2.31.1

There are various issues regarding DebugImageInfoTable:
1) Interrupting the table updates (e.g. an exception occured) may
leave the table in an inconsistent state.
2) Deleting an entry from the table may hide a different entry.
3) The type of image entries is not checked before accessing them as
NormalImage. This is practically safe now, because there is only one
type, but it adding more types would cause the accesses to
potentially invoke Undefined Behaviour.
4) The guarantees the table gives are not clear. For example, the
LoadedImage protocol instance can never be NULL (and wouldn't make
sense to be either), yet it is checked in some places, but not in
others.

This patch series addresses all of these issues.

Hi Leif，

According to your advice, I have changed the name of header to OemHisiMiscLib and snet the v2 patch to you. Please help reviewing it when you are free.

Thanks
Wenyi

So this patch changes the call of copy2() to copyfile().

DebugImageInfoTable updates

Good day Hao,

Sorry for the confusion, and you are (rightfully!) not alone. :( I'll quote myself
from a different patch:

[...] for some reason, none of the other patch series had indices appended.
I'm sure I can get that fixed shortly, but what to do then, re-send the entire
bulk? I don't want to spam the list, maybe it is smarter to group them by
some overview mail this one time?

I would suggest to send a V2 series for all the patches (not only limited to MdeModulePkg) you sent.

Right, I can do that, just many of the patches were actually meant to be single and independent. I believe there were two series that somehow did not get indexed by the command. I just forced numbering now and it seems to work.

May it be easier if I re-send only the two series? A few of the individual patches actually started review.

Thanks for your suggestions, and sorry again for the disruption!

Best regards,
Marvin

Please ensure that patches belong to one series are generated by a single 'git format-patch' command.
I think doing so will add information like '1/n', '2/n', ..., 'n/n' for the patches in one series.
And you may need to create a cover-letter for one patch series to give a brief summary on the purpose of the series as a whole.

Also, if you are implementing a new feature or a fix that touches many modules, I suggest to file a Bugzilla tracker for it:
Feature request: https://bugzilla.tianocore.org/enter_bug.cgi?product=Tianocore%20Feature%20Requests
Bugfix: https://bugzilla.tianocore.org/enter_bug.cgi?product=EDK2

Lastly, you may keep the 'Reviewed-by' tags already received by other reviewers.

Best Regards,
Hao Wu

Sorry for the disruption!

Best regards,
Marvin

Subject: [PATCH] MdeModulePkg/DxeCore: Consistent

DebugImageInfoTable

updates

In theory, modifications to the DebugImageInfoTable may cause

exceptions.

If the exception handler parses the table, this can lead to
subsequent exceptions if the table state is inconsistent.

Ensure the DebugImageInfoTable remains consistent during modifications.
This includes:
1) Free the old table only only after the new table has been published.
Mitigates use-after-free of the old table.
2) Do not insert an image entry till it is fully initialised. Entries
may be inserted in the live range if an entry was deleted previously.
Mitigaes the usage of inconsistent entries.
3) Free the old image entry only after the table has been updated
with the NULL value. Mitigates use-after-free of the old entry.
4) Set the MODIFIED state before performing any modifications.
