[PATCH v2 1/2] BaseTools: Define the read-only data section name per toolchain


Marvin Häuser
 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3318

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.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3318

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best. 

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation? Also see above regarding compiler-emitted __DATA,__const.

Thanks for your notes and insight!

Best regards,
Marvin

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].

Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.

This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.

Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?

The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly. 

Also see above regarding compiler-emitted __DATA,__const.


OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section. 

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`. We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata? I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.

I forgot I have an Ubuntu VM so we can take a look at an ELF to PE/COFF  toolchain example ….

So it looks like nasm[1] “does the right thing”(tm) and places a .rodata section in the object file….

But it looks like GenFw[2] smashed the .rodata section into .data section when it translated to PE/COFF. This was the issue I was worried about…. 

Actually I should probably look at the ELF executable too[3]. Yikes no .rodata in the ELF. So it looks likely that the linker scripts are smashing .rodata into .data. So there may be multiple issues with ELF toolchains that need to change to end up with a .rodata in the PE/COFF.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].

Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.

This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.

Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?

The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly. 

Also see above regarding compiler-emitted __DATA,__const.


OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section. 

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`. We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata? I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.

I forgot I have an Ubuntu VM so we can take a look at an ELF to PE/COFF  toolchain example ….

So it looks like nasm[1] “does the right thing”(tm) and places a .rodata section in the object file….

But it looks like GenFw[2] smashed the .rodata section into .data section when it translated to PE/COFF. This was the issue I was worried about….

Actually I should probably look at the ELF executable too[3]. Yikes no .rodata in the ELF. So it looks likely that the linker scripts are smashing .rodata into .data.
They smash it into .text, as linked in the other mail [1]. This is fine honestly, just I want some toggle that decides consistently for all toolchains what to do (merge into .text or let it live as a separate section). But that'd be a task for another patch.

So there may be multiple issues with ELF toolchains that need to change to end up with a .rodata in the PE/COFF.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.

Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`. We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata? I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.


Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?

We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?

Marvin

Actually I should probably look at the ELF executable too[3]. Yikes no .rodata in the ELF. So it looks likely that the linker scripts are smashing .rodata into .data.
They smash it into .text, as linked in the other mail [1].
Sorry I get way to much email…..

This is fine honestly, just I want some toggle that decides consistently for all toolchains what to do (merge into .text or let it live as a separate section). But that'd be a task for another patch.
I’m still trying to wrap my head around the definition of the nasm RODATA_SECTION_NAME. Do we want it to track what ends up in the object file, the native executable, or the PE/COFF?

It seems like it is tracking the object file. If that is the case we can just fix the XCODE changes to use `__TEXT,__const`and all the toolchains would be consistent.

I’d like to see the commit message reworked to better define what is going on. RODATA_SECTION_NAME tracks what end up object file, and PE/COFF results are controlled by the linker script/GenFw or mtoc.

So there may be multiple issues with ELF toolchains that need to change to end up with a .rodata in the PE/COFF.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.

Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1] gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`. We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata? I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?


The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.


If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.
It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.


Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1] gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?


We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?
I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.

Thanks,

Andrew Fish

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.
It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.
(I think all open ends of the other threads are in here too, so let's drop them and go on only here?)

Right, ok, thanks!

Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1] gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?
Yes, it is for NASM. My point is, the actual issue is not that my macro uses __DATA,__const, but that __DATA,__const is not merged into .text, but into .data. Fixing the macro fixes where the NASM definitions go, but what about the C definitions? I cannot test it, as I said, because I don't have an Xcode machine, but let's say we have a stupid example like this:

volatile UINT32 a;
volatile UINT32 *CONST p = &a;

The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?

We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?
I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.
Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.

Marvin

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.

It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.

(I think all open ends of the other threads are in here too, so let's drop them and go on only here?)

Right, ok, thanks!

Also see above regarding compiler-emitted __DATA,__const.

OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?

Yes, it is for NASM. My point is, the actual issue is not that my macro uses __DATA,__const, but that __DATA,__const is not merged into .text, but into .data. Fixing the macro fixes where the NASM definitions go, but what about the C definitions? I cannot test it, as I said, because I don't have an Xcode machine, but let's say we have a stupid example like this:

volatile UINT32 a;
volatile UINT32 *CONST p = &a;


In this case p ends up in a __DATA__,__const section since &a requires a relocation. 


The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?

I don’t see your bigger point. The compiler is free to implement as it sees fit. Which section some code ends up in is more of an implementation detail for the compiler, and we can’t really depend on that?


We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?

I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.

Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.


OK then please refactor the commit message to make it clear that this patch is to get the correct section in the object files, and work is still need to get this into executable images. 

For Xcode you can make it __DATA__,__const since that is the closest thing to read only data and I think that is your intent. 

GenFW is part of EDKII BaseTools and mtoc is part of the open source CCTOOLS project and both those tools would need to be modified to create a .rodata section in PE/COFF.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.
It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.
(I think all open ends of the other threads are in here too, so let's drop them and go on only here?)

Right, ok, thanks!

Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?
Yes, it is for NASM. My point is, the actual issue is not that my macro uses __DATA,__const, but that __DATA,__const is not merged into .text, but into .data. Fixing the macro fixes where the NASM definitions go, but what about the C definitions? I cannot test it, as I said, because I don't have an Xcode machine, but let's say we have a stupid example like this:

volatile UINT32 a;
volatile UINT32 *CONST p = &a;
In this case p ends up in a __DATA__,__const section since &a requires a relocation.
OK, good, thanks!



The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?
I don’t see your bigger point. The compiler is free to implement as it sees fit. Which section some code ends up in is more of an implementation detail for the compiler, and we can’t really depend on that?
Your point, rightfully, was that things that we request to be read-only (may) end up being read-write. My issue is that, if the compiler requests this pointer to be read-only (it may not, but also it may), our PE executable does not honour it either. __DATA,__const is a section for constant data, and we put it into a read-write section. The bigger point is, whenever the compile stack wants something read-only (be that NASM or be that Apple Clang, anything really), we should actually ensure it is read-only. I can do that for only NASM by forcing the __TEXT,__const section name (at the cost of prohibiting relocs), but I do not know how to do it for Apple Clang. At worst we could take a hacked-ish solution, where all Mach-O segments are converted to PE/COFF sections - with the exception of the __DATA,__const section, which, if aligned on a segment alignment boundary, can be inserted between the two other parts .data is split into. I read in the XNU source that the ARM protection code does something roughly like this [1], but I'm really far from well-versed in the deep details of macOS.

Sorry for this not being "integrated" in above text, but I found two more things while looking for citation 1.

1) Mach-O sections can be renamed, including the preceding segment name [2]. According to the very next line, the example actually creates a new segment. Does it allow merging into another, existing segment? What if I did something like:

-Wl,-rename_section,__DATA,__const,__TEXT,__const2

or even

-Wl,-rename_section,__DATA,__const,__TEXT,__const

i.e. can it merge two sections together? if __DATA,__const had data with relocs, would the renaming trigger the "no relocs" error of __TEXT, or does that happen before section renaming? Any chance it can be turned off?

1.1) Actually, for the standalone .rodata section, we can just rename it to __DATA_CONST,__const, as I have seen elsewhere in XNU. No hacked-ish solution needed. :)

2) We actually can force the compiler to put data in the constant data segment [3]. This is of course not used in EDK II, and probably neither portable nor necessary, but an interesting detail. I really think we should honour it either way.

I will likely try to get my hands on some sort of Apple development environment soon, but I cannot promise much right now. I think it really is better if I can test through all toolchains myself. If you release Apple Clang for Linux, I also won't complain of course. :)



We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?
I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.
Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.
OK then please refactor the commit message to make it clear that this patch is to get the correct section in the object files, and work is still need to get this into executable images.
Sure.


For Xcode you can make it __DATA__,__const since that is the closest thing to read only data and I think that is your intent.
I would like to do that, but only if we can ensure __DATA,__const is merged into .text, or is a separate RNX section.


GenFW is part of EDKII BaseTools and mtoc is part of the open source CCTOOLS project and both those tools would need to be modified to create a .rodata section in PE/COFF.
Yes, that should not be a big problem. Remaining issues for me:
1) How to merge __DATA,__const into .text, or how to emit a standalone .rodata section, for Xcode-based toolchains? (Some ideas above, will ping Vitaly soon as well)
2) How to submit modified mtoc? Any chance it could be maintained in EDK II like GenFw? (Would be nice if you could provide some insight)
3) How to merge .rdata into .text for MSVC? (I will try to research this soon-ish, but no promises)
4) How to design a toggle for the platform maintainer to choose between .text merge and standalone .rodata?

Please note that I'm not asking you to research any of those questions (but 2) would be nice :) ), this is merely a summary of open points till the second stage (correct executables, not just correct object sections) can be properly approached.

Thanks for your time and insight!

The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?
I don’t see your bigger point. The compiler is free to implement as it sees fit. Which section some code ends up in is more of an implementation detail for the compiler, and we can’t really depend on that?
Your point, rightfully, was that things that we request to be read-only (may) end up being read-write. My issue is that, if the compiler requests this pointer to be read-only (it may not, but also it may), our PE executable does not honour it either. __DATA,__const is a section for constant data, and we put it into a read-write section. The bigger point is, whenever the compile stack wants something read-only (be that NASM or be that Apple Clang, anything really), we should actually ensure it is read-only. I can do that for only NASM by forcing the __TEXT,__const section name (at the cost of prohibiting relocs), but I do not know how to do it for Apple Clang. At worst we could take a hacked-ish solution, where all Mach-O segments are converted to PE/COFF sections - with the exception of the __DATA,__const section, which, if aligned on a segment alignment boundary, can be inserted between the two other parts .data is split into. I read in the XNU source that the ARM protection code does something roughly like this [1], but I'm really far from well-versed in the deep details of macOS.

Sorry for this not being "integrated" in above text, but I found two more things while looking for citation 1.

1) Mach-O sections can be renamed, including the preceding segment name [2]. According to the very next line, the example actually creates a new segment. Does it allow merging into another, existing segment? What if I did something like:

-Wl,-rename_section,__DATA,__const,__TEXT,__const2

or even

-Wl,-rename_section,__DATA,__const,__TEXT,__const
(I cut the upper part of the quote to make some room...)

Both worked as expected.


i.e. can it merge two sections together? if __DATA,__const had data with relocs, would the renaming trigger the "no relocs" error of __TEXT, or does that happen before section renaming? Any chance it can be turned off?
As feared, the error triggers. However I found a seemingly not-so-well-known flag for Apple ld64 to disable it: "-read_only_relocs suppress". In fact, it is already used for IA32 builds, but not for X64 builds? [1]

I also noticed the extent of the XCODE5 "exceptions", e.g. duplicated files [2]. The files seem to be out-of-sync, but interestingly the XCODE5 version is the one that is more current and used in other toolchain builds as well.

So, maybe we can do the following?
1) Pass "-read_only_relocs suppress" for X64 and clean up any XCODE5-specific workarounds for text relocations.
2) Use neither "__TEXT,__const" nor "__DATA,__const" for NASM_RODATA_SECTION_NAME, but "__DATA_CONST,__const". Give it RNX permissions.
3) Case-distinct between "generate standalone .rodata" and "merge .rodata into .text".
3.1) case 1: Rename "__TEXT,__const" and "__TEXT,__cstring" to "__DATA_CONST,__text_const" and "__DATA_CONST,__cstring" respectively.
3.2) case 2: Rename "__DATA_CONST,__const" to "__TEXT,__data_const".

Rationales:
1) There is no such concept in PE/COFF, we can discard it and align with PE/COFF and ELF toolchains. Allows ".rodata" merge into ".text".
2) There is no pre-existing segment for read-only data, so we create our own with a naming convention taken from XNU.
3.1) Both former sections do not contain executable code, so we properly enforce the separation introduced in 2). Choose unique names to not reduce the object file separation.
3.2) Merge ".rodata" into ".text" in the same way ELF toolchains do. Saves space and we get to keep read-only.

I can test both cases work fine soon.


1.1) Actually, for the standalone .rodata section, we can just rename it to __DATA_CONST,__const, as I have seen elsewhere in XNU. No hacked-ish solution needed. :)

2) We actually can force the compiler to put data in the constant data segment [3]. This is of course not used in EDK II, and probably neither portable nor necessary, but an interesting detail. I really think we should honour it either way.

I will likely try to get my hands on some sort of Apple development environment soon, but I cannot promise much right now. I think it really is better if I can test through all toolchains myself. If you release Apple Clang for Linux, I also won't complain of course. :)
I found a port of Apple ld64 for Linux. I get it's not "the real deal", but all observed behaviour matches what I've seen so far from Apple Xcode. Actually boots OVMF. :)

A side note, seems like even latest mtoc gives .data RWX no matter what? Ouch...

https://github.com/tianocore/edk2/blob/0a6b303dcedb7af238ad485d545802befb797b3a/UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ExceptionHandlerAsm.nasm




We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?
I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.
Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.
OK then please refactor the commit message to make it clear that this patch is to get the correct section in the object files, and work is still need to get this into executable images.
Sure.


For Xcode you can make it __DATA__,__const since that is the closest thing to read only data and I think that is your intent.
I would like to do that, but only if we can ensure __DATA,__const is merged into .text, or is a separate RNX section.


GenFW is part of EDKII BaseTools and mtoc is part of the open source CCTOOLS project and both those tools would need to be modified to create a .rodata section in PE/COFF.
Yes, that should not be a big problem. Remaining issues for me:
1) How to merge __DATA,__const into .text, or how to emit a standalone .rodata section, for Xcode-based toolchains? (Some ideas above, will ping Vitaly soon as well)
2) How to submit modified mtoc? Any chance it could be maintained in EDK II like GenFw? (Would be nice if you could provide some insight)
3) How to merge .rdata into .text for MSVC? (I will try to research this soon-ish, but no promises)
4) How to design a toggle for the platform maintainer to choose between .text merge and standalone .rodata?

Please note that I'm not asking you to research any of those questions (but 2) would be nice :) ), this is merely a summary of open points till the second stage (correct executables, not just correct object sections) can be properly approached.

Thanks for your time and insight!

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.
It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.
(I think all open ends of the other threads are in here too, so let's drop them and go on only here?)

Right, ok, thanks!

Also see above regarding compiler-emitted __DATA,__const.
OK so the current nasm `SECTION .rodata`[1] gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?
Yes, it is for NASM. My point is, the actual issue is not that my macro uses __DATA,__const, but that __DATA,__const is not merged into .text, but into .data. Fixing the macro fixes where the NASM definitions go, but what about the C definitions? I cannot test it, as I said, because I don't have an Xcode machine, but let's say we have a stupid example like this:

volatile UINT32 a;
volatile UINT32 *CONST p = &a;
In this case p ends up in a __DATA__,__const section since &a requires a relocation.
OK, good, thanks!



The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?
I don’t see your bigger point. The compiler is free to implement as it sees fit. Which section some code ends up in is more of an implementation detail for the compiler, and we can’t really depend on that?
Your point, rightfully, was that things that we request to be read-only (may) end up being read-write. My issue is that, if the compiler requests this pointer to be read-only (it may not, but also it may), our PE executable does not honour it either. __DATA,__const is a section for constant data, and we put it into a read-write section. The bigger point is, whenever the compile stack wants something read-only (be that NASM or be that Apple Clang, anything really), we should actually ensure it is read-only. I can do that for only NASM by forcing the __TEXT,__const section name (at the cost of prohibiting relocs), but I do not know how to do it for Apple Clang. At worst we could take a hacked-ish solution, where all Mach-O segments are converted to PE/COFF sections - with the exception of the __DATA,__const section, which, if aligned on a segment alignment boundary, can be inserted between the two other parts .data is split into. I read in the XNU source that the ARM protection code does something roughly like this [1], but I'm really far from well-versed in the deep details of macOS.

Sorry for this not being "integrated" in above text, but I found two more things while looking for citation 1.

1) Mach-O sections can be renamed, including the preceding segment name [2]. According to the very next line, the example actually creates a new segment. Does it allow merging into another, existing segment? What if I did something like:

-Wl,-rename_section,__DATA,__const,__TEXT,__const2

or even

-Wl,-rename_section,__DATA,__const,__TEXT,__const

i.e. can it merge two sections together? if __DATA,__const had data with relocs, would the renaming trigger the "no relocs" error of __TEXT, or does that happen before section renaming? Any chance it can be turned off?

1.1) Actually, for the standalone .rodata section, we can just rename it to __DATA_CONST,__const, as I have seen elsewhere in XNU. No hacked-ish solution needed. :)

2) We actually can force the compiler to put data in the constant data segment [3]. This is of course not used in EDK II, and probably neither portable nor necessary, but an interesting detail. I really think we should honour it either way.

I will likely try to get my hands on some sort of Apple development environment soon, but I cannot promise much right now. I think it really is better if I can test through all toolchains myself. If you release Apple Clang for Linux, I also won't complain of course. :)
When I ask compiler questions to my compiler peeps they sometime answer via: https://godbolt.org. You can pas -emit-llvm, -S, or actually run code all from the webpage. It lets you compare the output of lots of versions of clang and compare it with other compilers too. You might find that useful for your research.

For EFI/EDKII clang is mostly just clang (strange triple for x86_64). It is ld64 that is macOS specific, and there is not cross version of ld64 that I know about.

FYI I worked really closely with the owner of ld64, Nick, when we got EFI working. What looks like the strange set of args is what is required to make ld64 “do the right thing”. The biggest portability issue with ld64 is it does not support the GCC ld linker scripts.


I think I’ve forgotten to mention one, relevant, historical point. One of the reasons that sections got collapsed together was to save size. This is the same reason you see the page size/section alignment set to 0x20 (32 bytes). 32 bytes was the smallest alignment the VC++ would support back in the day. In recent times the runtime code got converted to 4K section alignment so the OS could provide better page based protection. That ended up not being too bad as all that code is stored compressed, and it compresses well. Usually the biggest size risk is PEI as it is common for chunks of that code to run directly from ROM, and you would be surprised how much complexity can be involved in turning on DRAM, and that makes for larger PEIMs.

Thanks,

Andrew Fish



We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?
I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.
Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.
OK then please refactor the commit message to make it clear that this patch is to get the correct section in the object files, and work is still need to get this into executable images.
Sure.


For Xcode you can make it __DATA__,__const since that is the closest thing to read only data and I think that is your intent.
I would like to do that, but only if we can ensure __DATA,__const is merged into .text, or is a separate RNX section.


GenFW is part of EDKII BaseTools and mtoc is part of the open source CCTOOLS project and both those tools would need to be modified to create a .rodata section in PE/COFF.
Yes, that should not be a big problem. Remaining issues for me:
1) How to merge __DATA,__const into .text, or how to emit a standalone .rodata section, for Xcode-based toolchains? (Some ideas above, will ping Vitaly soon as well)
2) How to submit modified mtoc? Any chance it could be maintained in EDK II like GenFw? (Would be nice if you could provide some insight)
3) How to merge .rdata into .text for MSVC? (I will try to research this soon-ish, but no promises)
4) How to design a toggle for the platform maintainer to choose between .text merge and standalone .rodata?

Please note that I'm not asking you to research any of those questions (but 2) would be nice :) ), this is merely a summary of open points till the second stage (correct executables, not just correct object sections) can be properly approached.

Thanks for your time and insight!

2.31.1











Andrew Fish
 

Just ran across this today and wanted to share. The NASM Chapter 7 [1] defines the behavior for .rodata for ELF and mach-O .

So the behavior is well defined. From 

7.8.1 macho extensions to the SECTION Directive

...

The default is data, unless the section name is __text or __bss in which case the default is text or bss, respectively.

For compatibility with other Unix platforms, the following standard names are also supported:

.text    = __TEXT,__text  text 
.rodata  = __DATA,__const data 
.data    = __DATA,__data  data 
.bss     = __DATA,__bss   bss

If the .rodata section contains no relocations, it is instead put into the __TEXT,__const section unless this section has already been specified explicitly. However, it is probably better to specify __TEXT,__const and__DATA,__const explicitly as appropriate.

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.

An EFI Mach-O file does not contain a .rodata section. A Mach-O contains a __DATA segment that is broken up into sections. For a typical EFI image there are __const, __data, __bss sections in the __DATA segment [1].
Yes, and ".rodata" is almost a synonym for "__DATA,__const", with a small exception [1]. Maybe it'd be clearer if the macro was renamed to "NASM_RODATA_SECTION_NAME", to indicate this is not just a "raw" name, but NASM gives it a semantic meaning?

The mtoc [2] tool used to convert mach-O to PE/COFF converts the entire __DATA segment (__const, __data, and __bss) into the .data section. Thus adding any kind of new data section is a no-op at best.
This is a part I missed, because I do not have an Xcode toolchain at hand, so thanks for investigating. However this, in my opinion, is a flaw with Mach-O/mtoc and not with my patch. It seems like the only difference between __TEXT,__const and __DATA,__const is whether the data is targeted by a relocation or not. Such a concept does not exist for PE/COFF (and I think not even for ELF, but I'm not too familiar with it), thus the logical PE/COFF section __DATA,__const should be merged into is .rdata (and .rdata may or may not be merged into .text in an earlier step, I assume transitivity). I could change the macro definition to explicitly declare __TEXT,__const, but that would still put the compiler-emitted data in the wrong section. Does Xcode provide anything remotely similar to GNU linker scripts which we can use to move the section?

Please also note that .rodata is used for Xcode-based toolchains already (in fact, all toolchains, and this is the issue), I'm not regressing anything. I just expected it to work fine as-is. This patch mainly fixed PE/COFF-based toolchains, which get both .rdata from the compiler and .rodata with RX permissions from NASM, because ".rodata" only has a semantic meaning for ELF and Mach-O outputs, but not for PE/COFF.

If you want something to be read only for Xcode/clang you are better off putting it in the __TEXT section [3]. The __TEXT section is read only and for X64 can not even contain relocations.
Well, this kind of is an issue. We would need to introduce an arbitrary constraint on the relocation part that holds only for Xcode-based toolchains. Does the compiler emit an error when data in __TEXT,__const is targeted by a relocation?
The Xcode linker emits a fatal error on X64 for a relocation in the __TEXT section, everything needs to be RIP relative and the compiler does that for free. We generally only run into this for hand coded assembler and the fix is to use RIP relative addressing in the assembly.
Good, thanks for confirming! Still, this would be a bit of an awkward constraints for Xcode only.

It is a physics problem we can’t fix, so I end up writing some patches to fix other peoples assembler from time to time. The CI building with Xcode helps with this a lot.

(I think all open ends of the other threads are in here too, so let's drop them and go on only here?)

Right, ok, thanks!

Also see above regarding compiler-emitted __DATA,__const.

OK so the current nasm `SECTION .rodata`[1]  gets mapped to __TEXT,__const[2] for Xcode clang, and this is done by nasm (I dumped the object file). GenFw and mtoc only run on executables, also they tend to be conservative as they need to keep the layout the same and the relative layout between sections the same, but in this case it is nasm placing the data in the text section.

So what I’d like to see in the patch is to define RODATA_SECTION_NAME to match what is actually happening. So for XCODE that would be `__TEXT,__const` not `.rodata`.
We can do that, but what to do about compiler-emitted __DATA,__const?
Sorry I don’t understand what RODATA_SECTION_NAME has to do with the compiler? I thought it was for nasm?

Yes, it is for NASM. My point is, the actual issue is not that my macro uses __DATA,__const, but that __DATA,__const is not merged into .text, but into .data. Fixing the macro fixes where the NASM definitions go, but what about the C definitions? I cannot test it, as I said, because I don't have an Xcode machine, but let's say we have a stupid example like this:

volatile UINT32 a;
volatile UINT32 *CONST p = &a;


In this case p ends up in a __DATA__,__const section since &a requires a relocation.

OK, good, thanks!



The value of p is constant, so it can be placed in a constant data section. p points to a global variable, so if the compiler does not manage to somehow turn this into relative addressing (let's assume it does not), it needs to generate a relocation. This means the compiler cannot put it in __TEXT,__const, so it has to put it in __DATA,__const (of course it could put it in other __DATA sections, but let's assume the compiler agrees this should be read-only). The very same issue will arise and no matter the choice of the compiler, this will end up in .data. Do you agree? Or do we have some guarantee that Apple Clang cannot emit __DATA,__const?

I don’t see your bigger point. The compiler is free to implement as it sees fit. Which section some code ends up in is more of an implementation detail for the compiler, and we can’t really depend on that?

Your point, rightfully, was that things that we request to be read-only (may) end up being read-write. My issue is that, if the compiler requests this pointer to be read-only (it may not, but also it may), our PE executable does not honour it either. __DATA,__const is a section for constant data, and we put it into a read-write section. The bigger point is, whenever the compile stack wants something read-only (be that NASM or be that Apple Clang, anything really), we should actually ensure it is read-only. I can do that for only NASM by forcing the __TEXT,__const section name (at the cost of prohibiting relocs), but I do not know how to do it for Apple Clang. At worst we could take a hacked-ish solution, where all Mach-O segments are converted to PE/COFF sections - with the exception of the __DATA,__const section, which, if aligned on a segment alignment boundary, can be inserted between the two other parts .data is split into. I read in the XNU source that the ARM protection code does something roughly like this [1], but I'm really far from well-versed in the deep details of macOS.

Sorry for this not being "integrated" in above text, but I found two more things while looking for citation 1.

1) Mach-O sections can be renamed, including the preceding segment name [2]. According to the very next line, the example actually creates a new segment. Does it allow merging into another, existing segment? What if I did something like:

-Wl,-rename_section,__DATA,__const,__TEXT,__const2

or even

-Wl,-rename_section,__DATA,__const,__TEXT,__const

i.e. can it merge two sections together? if __DATA,__const had data with relocs, would the renaming trigger the "no relocs" error of __TEXT, or does that happen before section renaming? Any chance it can be turned off?

1.1) Actually, for the standalone .rodata section, we can just rename it to __DATA_CONST,__const, as I have seen elsewhere in XNU. No hacked-ish solution needed. :)

2) We actually can force the compiler to put data in the constant data segment [3]. This is of course not used in EDK II, and probably neither portable nor necessary, but an interesting detail. I really think we should honour it either way.

I will likely try to get my hands on some sort of Apple development environment soon, but I cannot promise much right now. I think it really is better if I can test through all toolchains myself. If you release Apple Clang for Linux, I also won't complain of course. :)


When I ask compiler questions to my compiler peeps they sometime answer via: https://godbolt.org. You can pas -emit-llvm, -S, or actually run code all from the webpage. It lets you compare the output of lots of versions of clang and compare it with other compilers too. You might find that useful for your research. 

For EFI/EDKII clang is mostly just clang (strange triple for x86_64). It is ld64 that is macOS specific, and there is not  cross version of ld64 that I know about. 

FYI I worked really closely with the owner of ld64, Nick, when we got EFI working. What looks like the strange set of args is what is required to make ld64 “do the right thing”. The biggest portability issue with ld64 is it does not support the GCC ld linker scripts.


I think I’ve forgotten to mention one, relevant, historical point. One of the reasons that sections got collapsed together was to save size. This is the same reason you see the page size/section alignment set to 0x20 (32 bytes). 32 bytes was the smallest alignment the VC++ would support back in the day. In recent times the runtime code got converted to 4K section alignment so the OS could provide better page based protection. That ended up not being too bad as all that code is stored compressed, and it compresses well. Usually the biggest size risk is PEI as it is common for chunks of that code to run directly from ROM, and you would be surprised how much complexity can be involved in turning on DRAM, and that makes for larger PEIMs. 

Thanks,

Andrew Fish



We should double check what is happening for ELF on x86, ARM, RiskV, etc. and do the same thing. I assume all the tools that generate PE/COFF directly are good with .rodata?
They are not, that is the whole point of the patch in its current shape. .rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I think it is likely as simple as dumping the EFL object file in objdump or gdb for the given toolchain (like my Xcode example).

TL;DR It looks to me like nasm does some SECTION translations under the hood to make code portable, and I’d like to make sure we capture those in the new NASM_RODATA_SECTION_NAME. If some one is doing a security review having NASM_RODATA_SECTION_NAME is going to imply that a .rodata section is being used by that specific toolchain, and I think that is much worse than the current “magic” behavior in nasm. We are much better off explaining what is really happening, since it is not very obvious.
I feel like I'm too tired to get the point. Do you mean you want comments whenever this section name is used? Or comments in tools_def?

I think I’d settle for a more descriptive commit comment that better defines what the define means like I mentioned in the other mail.

Hmm no, we can do that too, but in that case I really want comments in the code. tools_def is not really documented at all, maybe it is time to introduce an example comment so at least new things get commented? Maybe just the start of a macro list. Relying on "git blame" to figure out simple things is rather awful.

One more thing from another thread: Yes, the new macro should refer to object file section naming. I want this patch to get object file sections proper and sound. From there on we can fix the linking stage to emit proper and sound executables in a later patch.


OK then please refactor the commit message to make it clear that this patch is to get the correct section in the object files, and work is still need to get this into executable images.

Sure.


For Xcode you can make it __DATA__,__const since that is the closest thing to read only data and I think that is your intent.

I would like to do that, but only if we can ensure __DATA,__const is merged into .text, or is a separate RNX section.


GenFW is part of EDKII BaseTools and mtoc is part of the open source CCTOOLS project and both those tools would need to be modified to create a .rodata section in PE/COFF.

Yes, that should not be a big problem. Remaining issues for me:
1) How to merge __DATA,__const into .text, or how to emit a standalone .rodata section, for Xcode-based toolchains? (Some ideas above, will ping Vitaly soon as well)
2) How to submit modified mtoc? Any chance it could be maintained in EDK II like GenFw? (Would be nice if you could provide some insight)
3) How to merge .rdata into .text for MSVC? (I will try to research this soon-ish, but no promises)
4) How to design a toggle for the platform maintainer to choose between .text merge and standalone .rodata?

Please note that I'm not asking you to research any of those questions (but 2) would be nice :) ), this is merely a summary of open points till the second stage (correct executables, not just correct object sections) can be properly approached.

Thanks for your time and insight!

Marvin
