Hi,

Here's v2 of the DWARF modversions series [1]. The main motivation
remains modversions support for Rust, which is important for
distributions like Android that are eager to ship Rust kernel
modules. However, per Luis' request [2], v2 drops all Rust specific
bits from the series and instead adds the feature as an option
for the entire kernel. Matt is addressing Rust modversion_info
compatibility issues in a separate series [3], and we'll follow up
with a patch to actually allow CONFIG_MODVERSIONS with Rust once
these have been sorted out.

A short background recap: Unlike C, Rust source code doesn't have
sufficient information about the final ABI, as the compiler has
considerable freedom in adjusting structure layout for improved
performance [4], for example, which makes using a source code
parser like genksyms a non-starter. Based on Matt's suggestion and
previous feedback from maintainers, this series uses DWARF debugging
information for computing versions. DWARF is an established and
a relatively stable format, which includes all the necessary ABI
details, and adding a CONFIG_DEBUG_INFO dependency for Rust symbol
versioning seems like a reasonable trade-off.

The first 16 patches of this series add a small tool for computing
symbol versions from DWARF, called gendwarfksyms. When passed a
list of exported symbols and an object file, the tool generates
an expanded type string for each symbol, and computes symbol CRCs
similarly to genksyms. gendwarfksyms is written in C and uses libdw
to process DWARF, mainly because of the existing support for C host
tools that use elfutils (e.g., objtool). The next two patches ensure
that debugging information is present where we need it and fix a
compilation issue with x86 asm-prototypes.h. The last patch adds
gendwarfksyms as an alternative to genksyms.

A quick note about performance: On my development system, building
x86_64 defconfig with MODVERSIONS takes about 59.4s with gcc 13
(avg. of ten runs). Adding DEBUG_INFO_DWARF5 increases the build
time by ~23% to 73.3s. Switching from GENKSYMS to GENDWARFKSYMS
reduces the build time by 6% to 68.9s, which is still ~16% slower
than genksyms without debugging information. Therefore, if you
already build kernels with debugging information, gendwarfksyms
should be slightly faster. YMMV, of course.

Things would change with LTO, because we won't have full DWARF
until we have an ELF binary, which means we'd have to process
vmlinux.o. This version of gendwarfksyms is still single-threaded
as it seems we can't rely on libdw to be thread-safe. Processing
a ThinLTO x86_64 defconfig vmlinux.o on my system takes ~2m16s,
and would have to happen even on incremental builds, just like
LTO linking itself. As cross-language LTO presumably isn't wildly
popular yet, gendwarfksyms intentionally depends in !LTO in this
version.

Looking forward to hearing your thoughts!

Sami

Changes in v2:
- Per Luis' request, dropped Rust-specific patches and added
  gendwarfksyms as an alternative to genksyms for the entire
  kernel.

- Added support for missing DWARF features needed to handle
  also non-Rust code.

- Changed symbol address matching to use the symbol table
  information instead of relying on addresses in DWARF.

- Added __gendwarfksyms_ptr patches to ensure the compiler emits
  the necessary type information in DWARF even for symbols that
  are defined in other TUs.

- Refactored debugging output and moved the more verbose output
  behind --dump* flags.

- Added a --symtypes flag for generating a genksyms-style
  symtypes output based on Petr's feedback, and refactored
  symbol version calculations to be based on symtypes instead
  of raw --dump-dies output.

- Based on feedback from Greg and Petr, added --stable flag and
  support for reserved data structure fields and declaration-onl
  structures. Also added examples for using these features.

- Added a GENDWARFKSYMS option and hooked up kbuild support
  for both C and assembly code. Note that with gendwarfksyms,
  we have to actually build a temporary .o file for calculating
  assembly modversions.

Hi Sami,

so this work is on top of Linux v6.11-rc3 - can you tag it as gendwarfksyms-v2?

Thanks.

I missed the examples for this, is there a Documentation/ update
somewhere to explain this?  What patch of the series handles this?

thanks,

Tested successfully against Linux v6.11-rc4+ with SLIM LLVM-toolchain
v18.0,8 from [1].

scripts/config -d LTO_CLANG -d LTO_CLANG_THIN
scripts/config -d GENKSYMS -e GENDWARFKSYMS

My first Clang-KCFI build without setting Clang-LTO.

Attached are my config and dmesg files.

Potentially silly question but: how similarly?  Specifically, do the two
tools generate the same CRCs for the same symbols?  It seems that might
be important for users transitioning to the new DWARF world order.

Thanks,

Reconstructing the source-based type strings genksyms uses from DWARF
wouldn't really be feasible, so the CRCs will be different. The
similar part is just that we build a human-readable string from the
debugging information and compute a CRC from it. If anyone is
interested in switching to gendwarfksyms, they'll have to rebuild all
their modules too.

Splitting a new tool into small chunks makes line-by-line review difficult.

For example, 02/19 adds malloc().

03/19 immediately replaces it with calloc().

Then, I wonder why you did not add calloc() in the first place.





And, I do not think it is so "small".
It is bigger than the current genksyms.

Why is "a list of exported symbols" passed separately?

All necessary information is available in the object file.
(The export symbols are listed in the .export_symbol section.

I do not know if this is worthwhile.


And, it is obviously a build error.

gendwarfksyms cannot create %.symtypes from %.c.


The following is the step to see the build error.

I split this into smaller pieces to make it less of a chore to
review, but I'm also happy to squash these into larger patches if you
prefer. How would you like to see this split instead?

Yes, that wasn't ideal, but like I said in my other response, I tried
to keep the churn minimal. Please let me know if you spot any other
annoyances.

In my defense, the first version was smaller, but sure, I'll drop the
false advertising from the cover letter now that it has more features.

Unfortunately this is not the case for Rust object files where exports
are handled separately. Passing the list of symbols as input feels
more flexible to me, and also is rather convenient for debugging.

Greg, Petr, do you want to comment on the usefulness of the symtypes
output? I was under the impression it was a useful tool for figuring
out exactly what caused the versions to change?

Ah, this obviously needs to depends on the .o files instead. I'll sort
this out in v3.

Thanks for taking a look!

Right, the symtypes data is useful if distributions wish to maintain
stable kABI for their kernels. The data can be compressed/consolidated
and stored together with the source code for the distribution kernel,
serving as a reference kABI. Later, when the kernel is updated and CRCs
of some symbols change, the reference can be compared with the new
symtypes data to understand what has actually changed.

The previous discussion was under v1 of the series:
