           Summary: libbpf: failed to find BTF info for global/extern
                    symbol 'bpf_link_fops'
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal

--- Comment #3 from David Faust <david.faust at oracle dot com> ---
There are two remaining issues:

1. We are missing support for 'linkage=extern' encoding for variables,
   so 'bpf_link_fops' and others are incorrectly marked with 'linkage=global'
   instead.

2. 'bpf_link_fops' variable is encoded as 'void' type not 'const void'.
   This is a result of the BTF being generated from internal DWARF
   representation. The distinction seems to be intentionally removed in
   dwarf2out.cc:add_type_attribute(), with the later side-effect that
   looking up the type DIE for the variable when generating BTF actually
   fails and falls back to the default 'void'.

I have an implementation for (1) in progress. For (2) I need to understand
why the 'void'/'const void' distinction is removed in DWARF and how to work 
around it.

proposed patch

Should fix the remaining issues with 'extern' linkage and the missing 'const'
modifier (and includes the earlier partial fixes in this bug)

Fixes the reported test failure but some others(unclear if related to this bug)

unsigned long long load_word(void *skb,
                             unsigned long long off) asm("llvm.bpf.load.word");

Looks like LLVM-specific inline asm to use their llvm.bpf.load.word intrinsic.

GCC has equivalent __builtin_load_{byte,half,word} target builtins.

Hm, looks like we are OK for extern variables but are mis-generating something
(or missing something) for extern funcs still. Will look into this.

Update the 'extern' variable marking, and also mark 'extern' funcs.

That fixes the issue in kfunc_call_test.c but I'm still hitting a few like this

    btf: fix 'extern const void' variables [PR106773]

    The eBPF loader expects to find BTF_KIND_VAR records for references to
    extern const void symbols. We were mistakenly identifing these as
    unsupported types, and as a result skipping emitting VAR records for
    them.

    In addition, the internal DWARF representation from which BTF is
    produced does not generate 'const' modifier DIEs for the void type,
    which meant in BTF the 'const' qualifier was dropped for 'extern const
    void' variables. This patch also adds support for generating a const
    void type in BTF to correct emission for these variables.
