            Bug ID: 30583
           Summary: RFE: Export all IFUNCs as @GLIBC_PRIVATE symbols to
                    support overrides via audtior (LD_AUDIT)
           Product: glibc
           Version: 2.38
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: libc

  Target Milestone: ---

We should make it easy for users to experiement with the different
implementations of IFUNCs.

One way to do this is to use GLIBC_TUNABLES, but this is often crude and
applies to all IFUNCs, not just one.

What we should really do is export all IFUNCs as @GLIBC_PRIVATE symbols to
allow a user-written audit module (LD_AUDIT) to select a specific IFUNC dur=
ing
binding.
