[ASan] Shared optimized callbacks implementation.
ClosedPublic

Authored by kstoimenov on Nov 24 2021, 12:08 PM.

Details

Summary

This change moves optimized callbacks from each .o file to compiler-rt. Instead of using code generation it uses direct assembly implementation. Please note that the 'or' version is not implemented and it will produce unresolved external if somehow 'or' version is requested.

can you commit this line reordering separately and rebase the patch

351 ↗(On Diff #389622)

I see SHADOW_OFFSET_STR neither in existing code nor in the patch
Is some file is missing or another patch.

compiler-rt/lib/sanitizer_common/sanitizer_shadow_defines.h

why it's in common? these constants are asan specific

61 ↗(On Diff #389622)

why do you need x86_64 in nname?

Nit: Can we omit the semicolons?

88 ↗(On Diff #389622)
99 ↗(On Diff #389622)

I think we also need to handle the 16 byte case.

compiler-rt/lib/sanitizer_common/sanitizer_shadow_defines.h
32 ↗(On Diff #389622)

Looks like in asan_mapping.h this value is 0xd55550000.

46 ↗(On Diff #389622)

Why is the offset 0 for all these platforms? It looks like they have non-zero in asan_mapping.h.

compiler-rt/test/asan/TestCases/Linux/interface_symbols_linux.cpp

Why is this step required now?

42 ↗(On Diff #389622)

Maybe I've confused myself, but isn't this condition opposite of what we want?

if (last_accessed_byte >= shadow_value) crash()

would translate to

cmp %ecx, %r8d
...
jl RLABEL(...)

or

cmp %r8d, %ecx
...
jg RLABEL(...)

Unfortunately no. The issue is that macros are expanded as single line and ; is used instead of a new line character.

Here is the disassembled version of __asan_load1:

mov    %rdi,%rax

jne    <__asan_load1+0x13>

Good catch!

compiler-rt/lib/asan/asan_shadow_defines.h

Fixed 0 constants. @morehouse PTAL.

compiler-rt/lib/asan/tests/asan_noinst_test.cpp
351 ↗(On Diff #389622)

It is supposed to be SHADOW_OFFSET. Good catch.

compiler-rt/test/asan/TestCases/Linux/interface_symbols_linux.cpp
4 ↗(On Diff #389622)

It runs the preprocessor, which will produce platform specific files for the platform as they are guarded by #ifdef in the asan_interface.inc file.

61 ↗(On Diff #389622)

No, it doesn't. Removed.

Updated comments to reflect the R10, R11 change.

kstoimenov updated this revision to Diff 391336.Dec 2 2021, 8:25 AM

Fixed SHADOW_OFFSET_CONST.

compiler-rt/lib/asan/tests/asan_noinst_test.cpp
351 ↗(On Diff #389622)

Correction:
It should be SHADOW_OFFSET_CONST.

kstoimenov updated this revision to Diff 391365.Dec 2 2021, 9:41 AM

Fixed the test and SHADOW_OFFSET_CONST.

Added an error message.

I would recommend to separate llvm into a separate patch, so you can land compiler-rt separately. That part is likely NFC on it's own, but you can wait some time to see if it was not reverted because of breaking. And then you can land/revert llvm part as many times you want

compiler-rt/lib/asan/asan_mapping.h
160–225

it would be nice to move formating out of the patch and submit separately, review is not required

compiler-rt/lib/asan/asan_rtl_x86_64.S
88 ↗(On Diff #389622)

it's back again?

compiler-rt/lib/asan/asan_shadow_defines.h
17 ↗(On Diff #391374)

why can't you move this into asan_mapping.h?

compiler-rt/lib/asan/tests/asan_noinst_test.cpp
331 ↗(On Diff #391374)

ASAN_MEMORY_ACCESS_CALLBACKS_ADD -> TEST_ASAN_MEMORY_ACCESS_CALLBACKS_ADD

because it instantiates tests

After landing format fix.

Can you do an opposite? include this one into asan_mapping and use SHADOW_OFFSET_CONST there.
