[PATCH v2 00/19] Implement DWARF modversions

[PATCH v2 00/19] Implement DWARF modversions

[Sami Tolvanen]

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!

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.

[PATCH v2 01/19] tools: Add gendwarfksyms

[Sami Tolvanen]

Add a basic DWARF parser, which uses libdw to traverse the debugging
information in an object file and looks for functions and variables.
In follow-up patches, this will be expanded to produce symbol versions
for CONFIG_MODVERSIONS from DWARF.

[PATCH v2 03/19] gendwarfksyms: Add address matching

[Sami Tolvanen]

The compiler may choose not to emit type information in DWARF for all
aliases, but it's possible for each alias to be exported separately.
To ensure we find type information for the aliases as well, read
{section, address} tuples from the symbol table and match symbols also
by address.

[PATCH v2 04/19] gendwarfksyms: Add support for type pointers

[Sami Tolvanen]

The compiler may choose not to emit type information in DWARF for
external symbols. Clang, for example, does this for symbols not
defined in the current TU.

To provide a way to work around this issue, add support for
__gendwarfksyms_ptr_<symbol> pointers that force the compiler to emit
the necessary type information in DWARF also for the missing symbols.

Example usage:

  #define GENDWARFKSYMS_PTR(sym) \
      static typeof(sym) *__gendwarfksyms_ptr_##sym __used  \
          __section(".discard.gendwarfksyms") = &sym;

  extern int external_symbol(void);
  GENDWARFKSYMS_PTR(external_symbol);

[PATCH v2 06/19] gendwarfksyms: Add a cache for processed DIEs

[Sami Tolvanen]

Basic types in DWARF repeat frequently and traversing the DIEs using
libdw is relatively slow. Add a simple hashtable based cache for the
processed DIEs.

[PATCH v2 07/19] gendwarfksyms: Expand type modifiers and typedefs

[Sami Tolvanen]

Add support for expanding DWARF type modifiers, such as pointers,
const values etc., and typedefs. These types all have DW_AT_type
attribute pointing to the underlying type, and thus produce similar
output.

Also add linebreaks and indentation to debugging output to make it
more readable.

[PATCH v2 11/19] gendwarfksyms: Limit structure expansion

[Sami Tolvanen]

Expand each structure type only once per exported symbol. This
is necessary to support self-referential structures, which would
otherwise result in infinite recursion, but is still sufficient for
catching ABI changes.

For pointers to structure types, limit type expansion inside the
pointer to two levels. This should be plenty for detecting ABI
differences, but it stops us from pulling in half the kernel for
types that contain pointers to large kernel data structures, like
task_struct, for example.

[PATCH v2 12/19] gendwarfksyms: Add die_map debugging

[Sami Tolvanen]

Debugging the DWARF processing can be somewhat challenging, so add
more detailed debugging output for die_map operations. Move parsed
die_map output behind --dump-dies to clean up the --debug output, and
add a --dump-die-map flag, which adds highlighted tags to the output
about die_map operations.

[PATCH v2 13/19] gendwarfksyms: Add symtypes output

[Sami Tolvanen]

Add support for producing genksyms-style symtypes files. Process
die_map to find the longest expansions for each type, and use symtypes
references in type definitions. The basic file format is similar to
genksyms, with two notable exceptions:

  1. Type names with spaces (common with Rust) in references are
     wrapped in single quotes. E.g.:

     s#'core::result::Result<u8, core::num::error::ParseIntError>'

  2. The actual type definition is the simple parsed DWARF format we
     output with --dump-dies, not the preprocessed C-style format
     genksyms produces.

[PATCH v2 15/19] gendwarfksyms: Add support for declaration-only data structures

[Sami Tolvanen]

If a source file refers to an opaque data structure, the DWARF
debugging information in the resulting object file will only contain a
structure declation, which means the contents of the structure are not
included when computing symbol versions. For example:

Source code:

  struct struct0;
  int func(struct struct0 *);

gendwarfksyms --debug:

  subprogram(
    formal_parameter pointer_type <unnamed> {
      structure_type struct0 {
        <declaration>
      }
    } byte_size(8),
  )
  -> base_type int byte_size(4) encoding(5);
  #SYMVER func 0x7e8284f9

The declaration can change into a full definition when an additional
include is added to the TU, which changes the version CRC, even though
the ABI has not changed. If this happens during an LTS update, a
distribution that wants to maintain a stable ABI needs a way to ensure
symbol versions remain unchanged.

With genksyms, the usual solution is to use #ifndef __GENKSYMS__ to
skip the newly added header file when computing symbol versions, but
that's not an option when we're processing a precompiled object file.

To support this use case, add a --stable command line flag that gates
kABI stability features that are not needed in mainline, but can be
useful for distributions, and add support for symbol annotations that
allow structures to always be treated as declarations when versions
are computed. If a __gendwarfksyms_declonly_<structname> symbol
exists in the object file's symbol table, the "structname" structure
is treated as a declaration only, and not expanded when computing
versions. The symbol can be defined using the following macro, for
example, which discards it from the final kernel binary:

  #define GENDWARFKSYMS_DECLONLY(structname) \
      static void *__gendwarfksyms_declonly_##structname __used \
        __section(".discard.gendwarfksyms")

Now, if we include struct0 definition in our source code, and add a
declaration-only annotation, we have:

  struct struct0 { int a; };
  GENDWARFKSYMS_DECLONLY(struct0);
  int func(struct struct0 *);

gendwarfksyms --debug reflects the added definition:

  subprogram(
    formal_parameter pointer_type <unnamed> {
      structure_type struct0 {
        member base_type int byte_size(4) encoding(5) data_member_location(0),
      } byte_size(4)
    } byte_size(8),
  )
  -> base_type int byte_size(4) encoding(5);
  #SYMVER func 0xc0de983d

But with --debug --stable, the definition is ignored and we again
have the original symbol version:

  subprogram(
    formal_parameter pointer_type <unnamed> {
      structure_type struct0 {
        <declaration>
      }
    } byte_size(8),
  )
  -> base_type int byte_size(4) encoding(5);
  #SYMVER func 0x7e8284f9

[PATCH v2 16/19] gendwarfksyms: Add support for reserved structure fields

[Sami Tolvanen]

Distributions that want to maintain a stable kABI need the ability to
add reserved fields to kernel data structures that they anticipate
will be modified during the ABI support timeframe, either by LTS
updates or backports.

With genksyms, developers would typically hide changes to the reserved
fields from version calculation with #ifndef __GENKSYMS__, which would
result in the symbol version not changing even though the actual type
of the reserved field changes. When we process precompiled object
files, this is again not an option.

To support stable symbol versions for reserved fields, change the
union type processing to recognize field name prefixes, and if the
union contains a field name that starts with __kabi_reserved, only use
the type of that field for computing symbol versions. In other words,
let's assume we have a structure where we want to reserve space for
future changes:

  struct struct1 {
    long a;
    long __kabi_reserved_0; /* reserved for future use */
  };
  struct struct1 exported;

gendwarfksyms --debug produces the following output:

  variable structure_type struct1 {
    member base_type long int byte_size(8) encoding(5) data_member_location(0),
    member base_type long int byte_size(8) encoding(5) data_member_location(8),
  } byte_size(16);
  #SYMVER exported 0x67997f89

To take the reserved field into use, a distribution would replace it
with a union, with one of the fields keeping the __kabi_reserved name
prefix for the original type:

  struct struct1 {
    long a;
    union {
      long __kabi_reserved_0;
      struct {
          int b;
          int v;
      };
    };

gendwarfksyms --debug now produces the following output:

  variable structure_type struct1 {
    member base_type long int byte_size(8) encoding(5) data_member_location(0),
    member union_type <unnamed> {
      member base_type long int byte_size(8) encoding(5),
      member structure_type <unnamed> {
        member base_type int byte_size(4) encoding(5) data_member_location(0),
        member base_type int byte_size(4) encoding(5) data_member_location(4),
      } byte_size(8),
    } byte_size(8) data_member_location(8),
  } byte_size(16);
  #SYMVER exported 0x66916c41

But with --stable, gendwarfksyms only uses the reserved field for the
version calculation, thus leaving the symbol version unchanged:

  variable structure_type struct1 {
    member base_type long int byte_size(8) encoding(5) data_member_location(0),
    member base_type long int byte_size(8) encoding(5) data_member_location(8),
  } byte_size(16);
  #SYMVER exported 0x67997f89

[PATCH v2 17/19] export: Add __gendwarfksyms_ptr_ references to exported symbols

[Sami Tolvanen]

With gendwarfksyms, we need each TU where the EXPORT_SYMBOL() macro
is used to also contain DWARF type information for the symbols it
exports.  However, as a TU can also export external symbols and
compilers may choose not to emit debugging information for symbols not
defined in the current TU, the missing types will result in missing
symbol versions. Stand-alone assembly code also doesn't contain type
information for exported symbols, so we need to compile a temporary
object file with asm-prototypes.h instead, and similarly need to
ensure the DWARF in the temporary object file contains the necessary
types.

To always emit type information for external exports, add explicit
__gendwarfksyms_ptr_<symbol> references to them in EXPORT_SYMBOL().
gendwarfksyms will use the type information for __gendwarfksyms_ptr_*
if needed. Discard the pointers from the final binary to avoid further
bloat.

I missed the examples for this, is there a Documentation/ update

Ah, ignore my previous email, here's the --stable stuff.

But this all needs to go into some documentation somewhere, trying to
dig it out of a changelog is going to be impossible to point people at.

Seems semi-sane, I can live with this.

I don't know if you want to take the next step and provide examples of
how to use this in "easy to use macros" for it all, but if so, that
might be nice.  Especially as I have no idea how you are going to do
this with the rust side of things, this all will work for any structures
defined in .rs code, right?

I agree, which is why I included the details in the comments too.
There's also an example file if you scroll down a bit further, but I
can certainly add some actual documentation too. Since the --stable
bits are not really needed in the mainline kernel, do you prefer a
file in Documentation/ or is it sufficient to expand the example files
to include any missing details?

Is there something you'd change to make this more than semi-sane?

This should already work with the macros Android uses, for example,
with minor changes. The current example file doesn't include macro
wrappers, but I can add them in the next version.

Yes, Rust structures can use the same scheme. Accessing union members
might be less convenient than in C, but can presumably be wrapped in
helper macros if needed.

Ah, I missed the examples, I thought that was a test for the feature :)

Yes, it needs to be documented somewhere, and usually documentation is
in Documentation/ so that it shows up on the web and everywhere else.

I can't think of it, but perhaps we need a check somewhere to ensure
that these symbol names do NOT end up in the main kernel tree?

Or just keep this whole patch as an add-on on the end that is only
applied by the distro kernels and is not merged into mainline at all?

The Android macros are a copy of what SLES and RHEL does so that's good.

And yes, an example macro would be nice so we all don't have to reinvent
it yet-again like we have done already.  Consolidation is nice.

That feels ripe for problems for any rust code as forcing a helper macro
for a "normal" access to a structure field is going to be a lot of churn
over time.  Is the need for a macro due to the fact that accessing a
union is always considered "unsafe" in rust?  If that's the case, ick,
this is going to get even messier even faster as the need for sprinkling
unsafe accesses everywhere for what used to be a normal/safe one will
cause people to get nervous...

The reason for union field access being unsafe in Rust is that you can
easily shoot yourself in the foot. For example:

    union Foo {
        a: bool,
        b: i32,
    }

    let foo = Foo { b: 3 };
    println!("{}", unsafe { foo.a });

This is UB, since `3` is of course not a valid value for `bool`. With
unions the compiler doesn't know which variant is active.

Since unions are unsafe in Rust, we don't really use them directly (in
the `kernel` crate, we have 0 union definitions). Instead we use certain
unions from the stdlib such as `MaybeUninit`. But the fields of that
union are private and never accessed.

In general, unions in Rust are very important primitive types, but they
are seldomly used directly. Instead enums are used a lot more, since you
don't need to roll your own tagged unions.

For this use-case (the one in the patch), I don't really know if we want
to copy the approach from C. Do we even support exporting kABI from
Rust? If yes, then we I would recommend we tag it in the source code
instead of using a union. Here the example from the patch adapted:

    #[repr(C)] // needed for layout stability
    pub struct Struct1 {
        a: u64,
        #[kabi_reserved(u64)] // this marker is new
        _reserved: u64,
    }

And then to use the reserved field, you would do this:
    
    #[repr(C)]
    pub struct Struct1 {
        a: u64,
        #[kabi_reserved(u64)]
        b: Struct2,
    }

    #[repr(C)]
    pub struct Struct2 {
        b: i32,
        v: i32,
    }

The attribute would check that the size of the two types match and
gendwarfksyms would use the type given in "()" instead of the actual
type.

Understood, then why attempt to use a union for this type of "abi safe
padding"?

That's the goal here, you want to create an abi that can change over
time without "breaking" the abi.  Usually this is just adding additional
padding in structures to have room for new additions.

Remember the "goal" here is to NOT have to modify the places in the
kernel that use the new field in the structure, but for that to "just
work".  Your change here wouldn't allow that as any use of the new "b"
field would have to be through something in "Struct2", not directly in
Struct1, right?

We can mess with the structure definitions but we should not have to
touch the places where the structure fields are used at all.  If that's
going to be a requirement (as it sounds like it would with the use of
unsafe in the union), then this is not going to be a solution at all.

This definitely looks cleaner than unions in Rust, but how would this
scheme be visible in DWARF? You might also need to expand the annotation
to allow replacing one reserved field with multiple smaller ones without
using structs.

This confuses me, since I thought that in C you would need to use the
new fields. So for example we have

    void increment(struct struct1 *x)
    {
        x->a += 1;
    }

and then we do the extension and also want to increment `b`, then we
have to do this:

    void increment(struct struct1 *x)
    {
        x->a += 1;
        x->b += 1;
    }

I am not 100% sure if you meant the following problem: if a user uses
the `increment` function like this:

    struct struct1 x = { .a = 0, .__kabi_reserved_0 = 0 };
    increment(&x);

Then in the C example they don't need to change their usage. In Rust,
they would, but we shouldn't make the struct fields public, then they
can't create the struct using the initializer syntax, but instead we
would provide stable initialization functions. Translating the entire
example to Rust:

    impl Struct1 {
        pub fn new(a: u64) -> Self {
            Self { a, _reserved: 0 }
        }

        pub fn increment(&mut self) {
            self.a += 1;
        }
    }

Then after adding the new field, this becomes:

    impl Struct1 {
        pub fn new(a: u64) -> Self {
            Self { a, b: Struct2 { b: 0, v: 0 } }
        }

        pub fn increment(&mut self) {
            self.a += 1;
            self.b.b += 1;
        }
    }

So the following user would also not have to change the code:

    let mut x = Struct1::new(0);
    x.increment();

So the union approach *could* work and the users of the API would not
have to use `unsafe`. But doing it the way I suggest above is going to
be cleaner, as the people who use the API won't ever need to know of the
internals.

Hmm that's a good question, I have no idea how DWARF works. The way you
do it in this patch is just by the name of the field, right?

If Rust's DWARF output contains exact types names (I just checked this,
I *think* that this is the case, but I have never used/seen DWARF
before), we might be able to just create a `KAbiReserved<T, R>` type
that you search for instead of the attribute. The usage would then be
like this:

    #[repr(C)]
    pub struct Struct1 {
        a: u64,
        _reserved: KAbiReserved<(), u64>,
    }

And then when adding a new field, you would do this:

    #[repr(C)]
    pub struct Struct1 {
        a: u64,
        b: KAbiReserved<Struct2, u64>,
    }

    /* Struct2 as above */

The way `KAbiReserved` is implemented is via a `union` (maybe a bit
ironic, considering what I said in my other replies, but in this case,
we would provide a safe abstraction over this `union`, thus avoiding
exposing users of this type to `unsafe`):

    #[repr(C)]
    pub union KAbiReserved<T, R> {
        value: T,
        _reserved: R,
    }

    impl<T, R> Drop for KAbiReserved<T, R> {
        fn drop(&mut self) {
            let val = &mut **self;
            unsafe { ptr::drop_in_place(val) };
        }
    }

    impl<T, R> Deref for KAbiReserved<T, R> {
        type Target = T;

        fn deref(&self) -> &Self::Target {
            unsafe { &self.value }
        }
    }

    impl<T, R> DerefMut for KAbiReserved<T, R> {
        fn deref_mut(&mut self) -> &mut Self::Target {
            unsafe { &mut self.value }
        }
    }

    impl<T, R> KAbiReserved<T, R> {
        pub fn new(value: T) -> Self {
            // we want to ensure that people don't accidentally use a bigger type.
            build_assert!(size_of::<R>() >= size_of::<T>());
            Self { value }
        }

        pub fn into_value(self) -> T {
            unsafe { self.value }
        }
    }

This needs some more work, but is a lot cleaner than having the users
use raw unions + unsafe (essentially they would re-implement the code
above).

If you want me to turn the above into a patch let me know (also if you
or someone else wants to give it a try, then please go ahead! If you
need help, just send me a mail or a message on zulip).

Correct, it just looks at the name of the union fields.

I like this approach even better, assuming any remaining issues with
ownership etc. can be sorted out. This would also look identical to
the C version in DWARF if you rename _reserved in the union to
__kabi_reserved. Of course, we can always change gendwarfksyms to
support a different scheme for Rust code if a better solution comes
along later.

Agreement here - this seems like a good approach to representing
reserved in Rust code. A few minor adjustments we discussed off-list
which aren't required for gendwarfksyms to know about:
1. Types being added to reserved fields have to be `Copy`, e.g. they
must be `!Drop`.
2. Types being added to reserved fields must be legal to be
represented by all zeroes.
3. Reserved fields need to be initialized to zero before having their
union set to the provided value when constructing them.
4. It may be helpful to have delegating trait implementations to avoid
the couple places where autoderef won't handle the conversion.

While I think this is the right solution, esp. since it can share a
representation with C, I wanted to call out one minor shortfall - a
reserved field can only be replaced by one type. We could still
indicate a replacement by two fields the same as in C, by using a
tuple which will look like an anonymous struct. The limitation will be
that if two or more new fields were introduced, we'd need to edit the
patches accessing them to do foo.x.y and foo.x.z for their accesses
instead of simply foo.y and foo.z - the autoref trick only works for a
single type.

We will have to see how often multiple fields are added to a struct. If
they are infrequent and it's fine for those patches to then touch the
field accesses, then I think we can just stick with this approach.
If there are problems with that, we can also try the following:
all fields of kABI structs must be private and must only be accessed
through setters/getters. We can then modify the body the setters/getters
to handle the additional indirection.

If that also sounds too much work compared to the C side, then we can
get in touch with the Rust language folks and see if they can provide us
with a better solution.

That's just not going to work, sorry.  Remember, the goal here is to
keep the code that comes from kernel.org identical to what you have in
your "enterprise" kernel tree, with the exception of the few extra
"padding" fields you have added to allow for changes in the future in
the kernel.org versions.

Requiring all kernel.org changes that add a new field to a structure to
only do so with a settter/getter is going to just not fly at all as they
will not care one bit.

Or, we can just forget about "abi stability" for rust code entirely,
which I am totally fine with.  It's something that managers seem to like
for a "check box" but in reality, no one really needs it (hint, vendors
rebuild their code anyway.)

Yeah, that's what I thought.

The approach already works for a adding a single field and I got from
the discussions with Matthew and Sami that that is the most common case.
We will reach out to the Rust folks and see what we can do about the
multiple field case.

No, single field is NOT the common case, the common case is reserving
multiple padding variables in a structure as lots of things can change
of the long lifetimes of some of these kernel trees.  Look at the
changes in the Android or SLES or RHEL kernels for specifics.

Here's one example in the android tree where 4 64bit fields are reserved
for future abi changes:
	https://android.googlesource.com/kernel/common/+/refs/heads/android12-5.10/include/linux/fs.h#421

And here's a different place where a field is being used with many

Let me correct myself, it's only possible to replace one `KAbiReserved`
by one new field. You can have as many fields of type `KAbiReserved` as
you want. The thing that you can't do is replace a single `KAbiReserved`
field by multiple (well you can, but then you have to change the sites
that use it).

All of those structs need to be `repr(C)`, otherwise they don't
have a stable layout to begin with. Other than that, only autoderef
might be missing. But we would have to see if that even comes up.

> Or if not possible, just don't export any rust structures at all :)

I think that we should try to get this working.

Potentially silly question but: how similarly?  Specifically, do the two

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.

That's odd/foolish, why would that be the case?  Isn't that exactly what
a union is for?  How are you going to know ahead of time what size types
to save space for?

All we really want to do here is "pad out this structure by X bytes" and
then later "take X bytes to represent this variable" at a later point in
time.

Surely rust can do that, right?  :)

Do we have any way to enforce at build time that exports from rust code
are in this format to ensure that this will work properly going forward?
I guess someone is going to have to write the first api in rust that
actually gets used before we worry about this...

I believe Benno is referring to the lack of anonymous structures in
Rust. While you can replace a reserved field with a struct that
contains multiple smaller fields, you can't access the fields
transparently from the parent struct like you can in C:

    struct s { struct { u32 a; u32 b; }; };
    struct s s;
    s.a = 0;
    ...

It looks like nightly Rust does have some level of support for unnamed
fields in unions, but the implementation is not yet complete:

https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=4f268d308fe6aa7a47566c7080c6e604

Benno, Matt, are you familiar with this feature?

That's what I interpreted from the links you provided above, there are
multiple invocations of `ANDROID_KABI_RESERVE` and I figured they each
can be used to insert a new field. Or can you replace each one by as
many fields as you want, as long as the size is still fine?

Not with all the other things that you need. I feel like this discussion
is dragging a bit on, so we will just ask the Rust folks if they have
any suggestions and if they don't we will ask for a solution. We can
then get back to this when that's done.
It's not like we need this immediately.

I don't know if we already have a way, but we will need one if people
start writing kabi in Rust.

No, thanks for pointing that out!

But this will run into the issue that field access for unions is
`unsafe`. So we can't really use it. I also tried to use our current
`KAbiReserved<T, R>` approach and using this as `T`:

    struct Foo {
        _: struct { a: u32, b: u32 }
    }

But that doesn't work.

I see that libdwfl has also directly function dwfl_nextcu(). Would it

Isn't fd consumed by dwfl_report_offline() on success? I'm seeing EBADF

True, this could overflow object_files with a sufficient number of

How do you propose using the function? This loop goes through multiple
input files, should we need them, and we iterate through all the CUs
in process_modules.

Nit: extern isn't necessary here and in other similar cases throughout
the series. It should be removed per

The loop leaks line on a potential sscanf() error and name if the symbol
is a duplicate or malloc(sizeof(struct symbol)) fails. Additionally, it
should be possible to avoid allocating line by getline() on each
iteration.

I would change it to something like this (not tested):

int symbol_read_exports(FILE *file)
{
	struct symbol *sym;
	char *line = NULL;
	char *name = NULL;
	size_t size = 0;
	int nsym = 0;
	int ret = -1;

	while (getline(&line, &size, file) > 0) {
		if (sscanf(line, "%ms\n", &name) != 1) {
			error("malformed input line: %s", line);
			goto out;
		}

		if (is_exported(name)) {
			/* Ignore duplicates */
			free(name);
			name = NULL;
			continue;
		}

		sym = malloc(sizeof(struct symbol));
		if (!sym) {
			error("malloc failed");
			goto out;
		}

		sym->name = name;
		name = NULL;

		hash_add(symbol_names, &sym->name_hash, name_hash(sym->name));
		++nsym;

		debug("%s", sym->name);
	}

	debug("%d exported symbols", nsym);
	ret = 0;

out:
	free(line);
	free(name);
	return ret;
}

I would be careful and avoid including the padding between

I think strictly speaking this should be:
size_t nsyms = shdr->sh_size / shdr->sh_entsize;
.. and the code could check that shdr->sh_entsize is same as what
gelf_fsize(elf, ELF_T_SYM, 1, EV_CURRENT) returns.

The first symbol in the symbol table is always undefined, the loop can
start from 1.

Alternatively, since elf_for_each_symbol() ends up in the entire series
being used only with process_symbol() which skips symbols with the local
binding, the function could be renamed to elf_for_each_global_symbol()
and start the loop from shdr->sh_info.

Thanks for bringing this up. The license is inherited from the
genksyms code that's included in this series, but I'll consult with
our licensing folks and adjust this in v3 for the other parts if
needed.

Sure, I can change this. I'm not sure if there's a situation where the
current calculation wouldn't result in the exact same result though.

Patch 15 ("Add support for declaration-only data structures") actually
also needs to process local symbols, so we can't skip them completely.

Commit ddb5cdbafaaad6b99d7007ae1740403124502d03
had a similar idea; it has a reference to each
export symbol, including the ones defined in different TUs,
but in assembly code.

Didn't it suffice your need?

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.

Presumably, this is an unfortunate duplication, but I do not have an
idea to avoid it.

The symbol reference in assembly code works in *.S as well as *.c.

The C reference will pull-in the debug info, but it will not work in *.S

I was thinking it could be possible to replace the code to traverse
modules and their their CUs, that is functions process_modules() and
process_module(), with dwfl_nextcu(). However, I now notice that more
work is added in subsequent patches to process_modules() so this
wouldn't quite work.

I would then only suggest to change some function names in the current
code. Function process_modules() is a callback to process a single
module and so it would be better to name it process_module(). The
present function process_module() actually processes a compilation unit
DIE so I would rename it to something like process_cu().

Mostly a minor suggestion too.. Looking at the entire series, state.mod
ends up unused and state.dbg is only used in process_cached() where it
could be possibly replaced by doing dwarf_cu_getdwarf(die->cu)?

Removing these two members from the state struct would then allow to
instantiate a new state in process_exported_symbols() for each processed
symbol. That looks cleaner than changing state.sym and resetting some
parts of the state as the function walks over the exported symbols.

Sorry, I don't want to comment much on function names.. but I realized
the name of is_export_symbol() isn't really great. The "is_" prefix
strongly indicates that it is only a query function, yet it changes the
state. It makes its caller process_exported_symbols() hard to understand
on the first read.

Nit: The state parameter is unused by a number of these process_*()
functions, including the leaf process(). I suggest removing it so it
doesn't need to be passed around unnecessarily.

This check looks off by one, though on the safe side:

Failed check(process()) calls here return immediately and so would leak
scopes. However, I see this is fixed in the following patch
"gendwarfksyms: Add a cache for processed DIEs" so it's ok.

Why not getopt_long()?


See

So, this entirely traverses the singly-linked list
every time a new item is appended to the tail.


In my analysis, this while loop iterates for thousands
of times in total for emitting each export symbol.


Why isn't this list_add_tail()?

symbol_read_exports() is only called from main().

Do you need to make symbol_read_exports() return
the error code all the way back to the main()
function?

Personally, I'd like to make the program bail out as early as
possible if there is no point in continuing running.

I am tired of noise changes when reviewing this patch set.


2/19 added malloc(), which is immediately replaced with calloc() by 3/19.

Sure, sounds reasonable. I'll rename these.

Ah yes, mod was was leftover from previous refactoring. I'll clean this
up.

Right now it doesn't, but if we want to support LTO, we'll need to also
process the temporary object files we build for stand-alone assembly to
find types for the symbols exported there.

That's a valid point. The current error handling prints out a short
trace of exactly where something failed as the error propagates
through the call stack, but bailing out after printing the first
error is probably informative enough. I'll look into cleaning this
up.

Thanks for the link. In general I prefer to print out an error to
indicate what went wrong, but I suppose memory allocation errors
should be rare enough that it's not necessary. I'll switch to these
in the next version.

Here, no, but in Petr's cleaned up version it is again necessary, so

This was changed to calloc because the structure now has a new field
that should be zero-initialized, but I do agree, this could have
just been a calloc from the beginning. I'll change this in the next
version.

I did try to make sure there wouldn't be too much churn in the series,
but clearly I've missed a few places. Hopefully there's nothing
equally egregious in the later patches!

Correct. I'm not a huge fan of the extra reference either, but I don't
see a cleaner way to ensure we always have all the types in DWARF.

Yeah, I noticed this as well. I think Masahiro's suggestion to just

Good catch, I'll fix this in the next version. Keeping track of the

I split this into smaller pieces to make it less of a chore to

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

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

yes, this is one of the approaches we use in SLES. We add kabi paddings 
to some structures in advance (see [1] as a random example) and then use 
it later if needed.

It is not the only approach. Much more often we do not have a padding and 
use alignment holes ([5]), addition of a new member to the end of a 
structure ([2] or [3]) and such "tricks" ([4] for a newly fully defined 
structure).

It is not feasible to add kabi paddings to all structures. We also have a 
different approach to kabi in terms of its coverage than RHEL does for 
example (as far as I know).

Not sure if it is interesting to upstream but I wanted to mention that it 
is not only about the ability to add reserved fields to kernel structures 
in practice.

Thanks for bringing this up! Sounds like we're also going to need a
way to completely exclude specific fields from the output then. I
think we can use a similar union approach, but instead of instructing
the tool to use another type, we can just indicate that the field
should be skipped. I'll come up with a solution for v3.

Then, why don't you include <asm/ptrace.h>
from arch/x86/include/asm/ftrace.h
instead of from arch/x86/include/asm/asm-prototypes.h


And, this patch can get in independently.

You should send it as a standalone patch

I also tend to regard this kind comment line change as a noise.



I think you can squash 02/19 into 01/19 because
this tool does not do anything useful at this point.

These two lines can be replaced with

                  sym->addr = *addr;

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:

This slightly changes how scopes with no name are processed which is
unrelated to the added caching. The previous logic used "<unnamed>" for
individual unnamed scopes. The new code in such a case returns an empty
FQN which is turned in process_fqn() into "<unnamed>".

This is likely ok in practice for this particular tool. In general,
I think "<unnamed>" should be returned when the initial DIE is missing
a name and something like "<anonymous>::foo" when an outer scope has no
name.

More importantly, using "<unnamed>" when a type has no name looks to me
overly verbose, in particular, when it comes to the symtypes output. For
instance, the current output for a 'const char *' parameter is:
formal_parameter pointer_type <unnamed> { const_type <unnamed> { base_type char byte_size(1) encoding(8) } } byte_size(8)

.. while the following should be sufficient and easier to grasp:
formal_parameter pointer_type { const_type { base_type char byte_size(1) encoding(8) } } byte_size(8)

Small optimization: This loop could be written as follows to avoid
repeatedly searching the end of fqn:

char *p = *fqn;
for (i = 0; i < count; i++)
	p = stpcpy(p, list[i]);

As a small optimization and for consistency, I would recommended to also
cache the "<unnamed>" name to avoid repeatedly calling get_fqn() for
such DIEs.

If I understand correctly, this formatting logic also affects the
symtypes output. Looking at its format, I would like to propose a few
minor changes.

Example of the current symtypes output:
kprobe_event_cmd_init subprogram( formal_parameter pointer_type <unnamed> { s#dynevent_cmd } byte_size(8), formal_parameter pointer_type <unnamed> { base_type char byte_size(1) encoding(8) } byte_size(8), formal_parameter base_type int byte_size(4) encoding(5),  ) -> base_type void

Proposed changes:
kprobe_event_cmd_init subprogram ( formal_parameter pointer_type <unnamed> { s#dynevent_cmd } byte_size(8) , formal_parameter pointer_type <unnamed> { base_type char byte_size(1) encoding(8) } byte_size(8) , formal_parameter base_type int byte_size(4) encoding(5) ) -> base_type void
                                ^- (1)                                                                    ^- (2)                                                                                                                                                       ^- (3)

(1) "subprogram(" is split to "subprogram (".
(2) A space is added prior to ",".
(3) String ", " is removed after the last parameter.

Separating each token with a whitespace matches the current genksyms
format, makes the data trivially parsable and easy to pretty-print by
additional tools. If some tokens are merged, as in "subprogram(", then
such a tool needs to have extra logic to parse each word and split it
into tokens.

For attributes with one value, such as "byte_size(4)", I think the
current format is probably ok.

I'm quite worried about this optimization for pointer types. It could
result in some kABI changes not being recognized.

I assume the goal of the optimization is to speed up the tool's runtime.
How much does it improve the processing time and is there any other way
how it could be done?

I wonder if it would make sense to share the cache between processing
individual exported symbols.

The hard case looks to be the following:
s#A struct A { int ; }
s#B struct B { s#A ; }
foo void foo ( s#B )
bar void bar ( s#A , s#B )

When processing foo, the code would cache s#B with expanded s#A.
However, when processing bar and reaching s#B, the cache should report
a miss because s#B with unexpanded s#A is required.

So the code would need to track which types were already expanded and
have each cache entry accordingly tagged with similar data.

Hm, it might be that doing all this additional tracking would then be
actually slower than processing the types repeatedly for each symbol.
I'm not sure.

Could you include external headers first,
then in-tree headers?
(and one blank line in-between).



Also, please consider using scripts/include/hashtable.h



How about this?


#include <dwarf.h>
#include <elfutils/libdw.h>
#include <elfutils/libdwfl.h>
#include <inttypes.h>
#include <stdlib.h>
#include <stdio.h>

#include <hashtable.h>






If necessary, you can use this patch too:

I did consider that, but didn't find instances of anonymous scopes in
the output, so I simplified this a bit. I'll dig around a bit more and
change this if I find a use case. Note that going through the scopes
is mostly just needed for Rust code.

Agreed, that's way more readable. I'll drop the "<unnamed>" from the output.

True, I'll change this. Thanks!

Correct, it's passed directly to the symtypes output.

It’s mostly a matter of how deep it makes sense to go. For example,
queue_delayed_work_on accepts a pointer to s#workqueue_struct, which
points to s#worker, which points to s#task_struct, which points to
s#mm_struct etc. Does a change to an internal kernel data structure
several references deep change the ABI of the function?

If we traverse through the DWARF without limits, during a defconfig
build the highest pointer expansion depth I see is 70 levels (!), with
~5k symbols going 30+ levels deep. We would end up pulling in a lot of
major internal data structures at that point, and a change to any of
them would change thousands of symbol versions, which feels
undesirable.

I'm fine with increasing the limit to something more reasonable
though, the impact on performance doesn't seem to be significant in
parallel builds. Of course, this might impact vmlinux.o processing
more, if we end up doing that, since the DWARF at that point contains
information about all the data structures.

I do wonder if there's a better way to figure out where to stop than a
hard limit. Any thoughts?

The actual DIE caching happens in die_map, which is already shared
between symbols. The expansion cache keeps track of which DIEs we have
processed per symbol, so we don't process the same thing twice and end
up in a loop, for example.

Thanks for the patch! I think this would otherwise work, but I also
need jhash (or a similar hash function), and I can't combine the
tools/include version with this, because it ends up pulling in a
duplicate definition of struct list_head. Would you consider adding a
hash function as well?

I did it as a part of my kconfig works.

Check scripts/include/hash.h added by the following patches.

https://lore.kernel.org/linux-kbuild/20240908124352.1828890-1-masahiroy@kernel.org/T/#mea41ff4c5b6c77aaaae1ed9dac6723bc2f705107

I think simple helpers are enough for name_hash and addr_hash,
but please let me know if you encounter a problem.

Thank you for adding this output to the tool.

The fclose() call should be wrapped in check() to catch a situation when
flushing the stream potentially failed.

Nit: These defines should go into the patch 15/19 "gendwarfksyms: Add
support for declaration-only data structures".

I found the manipulation of type_expansion.expanded and
type_expansion.last somewhat strange.

The list starts already with one element in type_expansion_init(). This
is apparently to make the last pointer valid. This element is however
empty and gets only assigned on the first call to type_list_append().
Other elements are then added normally, always assigned.

Perhaps consider using a regular list implementation, similarly to what
was discussed under the patch 06/19 "gendwarfksyms: Add a cache for
processed DIEs".

Yeah, I noticed these too. Will fix in the next version.

Agreed, I'll switch this to a regular list in v3.

I think the CRC32 code should be ideally shared between genksyms and
gendwarfksyms. One option would be to stick it under scripts/include,
not sure if the best one though.

Nit: The "get_" prefix in the name of this function is misleading. It
isn't a plain getter but has an effect of setting the symbol die.
A different name would be better.

Nit: This cast removes constness. Is there a good reason why symbol.name
is 'const char *' instead of 'char *'?

The name of the function is also somewhat misleading. One would expect
that the function prints versions for all symbols, yet it has
a side-effect of freeing all symbol data. A different name or splitting
the function into two would be better.

Nit: The name parameter is unused.

More importantly, it made me think which names are included in the CRC
calculation and which ones are omitted.

If I'm looking correctly, names of structs, enums and enumerators make
it into the calculation. On the other hand, names of struct members,
function parameters and exports (functions/variables) are missing.

I think the names of struct members and function parameters should be
added as well. If the code changes 'struct A { int cols; int rows; }' to
'struct A { int rows; int cols; }' then that should be recognized as
a different API/ABI. The same applies to function parameters.

I'm not sure about export names. I would probably include them as well,
if only for consistency.

Genksyms incorporates in its calculation all of these names.

It might have been mentioned previously, not sure, but one more case to
consider is handling of enum declarations. New enumerators can be
typically added without breaking ABI, e.g. 'enum E { OLD1, OLD2, NEW }'.
It would be then great to have some ability to hide them from
gendwarfksyms.

I think neither of the __kabi_reserved or __gendwarfksyms_declonly
mechanism can currently help with that.

This was carried over from the initial version, which wasn't under
scripts yet. I'm happy to deduplicate this though. Masahiro, any
preferences on where this should go?

I did leave out member names because typically renaming a member
doesn't change the ABI, but you're right, it might help capture these
types of changes where fields with identical types are reordered for
some reason. I'll add names.

I would rather leave out the symbol names to have consistent CRCs
between symbols that have identical types. Or is there an actual
benefit in including the symbol name in the CRC? The names are already
rather explicitly involved when symbol versions are checked.

Ok with me. I can't think of a strong argument to do it one way or the
other.

I thought about this a bit and I wonder if we need a separate
mechanism for that, or is it sufficient to just #define any additional
hidden values you want to add instead of including them in the enum?

  enum e {
      A,
      B,
  #define C (B + 1)
  #define D (C + 1)
  };

Do you see any issues with this approach? I think Clang would complain
about this with -Wassign-enum, but I'm not sure if we even enable that
in the kernel, and as long as you don't overflow the underlying type,
which is a requirement for not breaking the ABI anyway, it should be
fine.

Rust has problems with `#define`-style enums, because bindgen (the tool
that generates definitions for Rust to be able to call C code) isn't
able to convert them to Rust enums.

So if you can come up with an approach that allows you to continue to
use C enums instead of `#define`, we would appreciate that, since it
would make our lives a lot easier.

That's an interesting point. Is the problem that you cannot assign
arbitrary values to the Rust enum that bindgen generates, or is using
a #define the problem? We could probably just make the hidden enum
values visible to bindgen only if needed.

So if I take your example from above add it to our bindgen input, then I
get the following output:

    pub const e_A: my_own_test_enum = 0;
    pub const e_B: my_own_test_enum = 1;
    pub type e_enum = core::ffi::c_uint;

So it doesn't pick up the other constants at all. That is probably
because we haven't enabled the bindgen flag that adds support for
function-like macros. If I enable that flag (`--clang-macro-fallback`,
then the output becomes:

    pub const C: u32 = 2;
    pub const D: u32 = 3;
    pub const e_A: e = 0;
    pub const e_B: e = 1;
    pub type e = ::std::os::raw::c_uint;

So it doesn't really work as we would like it to (ie missing e_ prefix).

But even if bindgen were to start supporting `#define` inside of the
enum. It might still have a problem with the `#define`: there is the
`--rustified-enum <REGEX>` option for bindgen that would change the
output to this:

    #[repr(u32)]
    #[derive(Debug, Copy, Clone, Hash, PartialEq, Eq)]
    pub enum e {
        A = 0,
        B = 1,
    }

Which makes using the values on the Rust side a lot easier, since you
get exhaustiveness checks when using `match`. Adding the
`--clang-macro-fallback` flag, I get:

    pub const C: u32 = 2;
    pub const D: u32 = 3;
    #[repr(u32)]
    #[derive(Debug, Copy, Clone, Hash, PartialEq, Eq)]
    pub enum e {
        A = 0,
        B = 1,
    }

Which is a big problem, because the enum `e` won't have 2 or 3 as valid
values (it will be UB to write them to a variable of type `e`).


Would you add conditions to the `#define`? For example checking for the
version of kABI? (or how would it work?)

Because we might want to have something similar on the Rust side then:

    #[repr(u32)]
    #[derive(Debug, Copy, Clone, Hash, PartialEq, Eq)]
    pub enum e {
        A = 0,
        B = 1,
        #[cfg(kabi >= "some-version")]
        C = 2,
        #[cfg(kabi >= "some-version")]
        B = 3,
    }

(still generated by bindgen though)

If defines are a problem, we can always use a const int instead. It
doesn't have to be defined inside the enum either, and probably we can
add a prefix too.

Yes, I sort of thought that this might be an issue. I don't see this
in bindgen flags right now, are you planning on switching the kernel
bindgen to use --rustified-enum?

If you do plan to use --rustified-enum, we could just use #ifdef
__BINDGEN__ to hide the fields from everyone else, but I think we
might actually need a more generic solution after all. I'll think
about it a bit more.

Perhaps the folks maintaining distros can chime in, but I suspect
there's typically one kABI version per branch, so there should be no
need to maintain multiple kABI versions in the same source file.

They might also be a problem, though I haven't checked. It would be best
if they can just stay in the `enum`.

You mean you don't see the `--clang-macro-fallback` option? I think it
was added in version 0.70.0.

Well we don't exactly plan to use `--rustified-enum`, the problem is
that transmuting the integer that C gives us to that enum is UB, when
the integer is not a valid bit pattern for that enum. Instead we would
like to have an option to generate both the Rust-style enum and a
newtype enum that can hold any integer value. We then check at runtime
that the value is in range and error otherwise. This is being worked on
at [1]. 
I would say that it has the same issue that `--rustified-enum` currently
has.
