Commit Message

Adhemerval Zanella Nov. 15, 2021, 6:37 p.m. UTC
The audit callback is not called for binaries built with -Wl,-z,now or
when LD_BIND_NOW=1 is used.  The PLT tracking callbacks are still not
issue for such case, since this will would change the expected program
semantic (where no PTL is expected) and also yield performance
implications (such as for BZ#15533).

To handle powerpc64 ELFv1 function descriptor, _dl_audit_symbind()
requires to know whether bind-now is used so the symbol value is
updated to function text segment instead of the OPD (for lazy binding
this is done by PPC64_LOAD_FUNCPTR on _dl_runtime_resolve).

Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
powerpc64-linux-gnu.
