elf: Issue la_symbind for bind-now (BZ #23734)
|
|
|
|
The audit symbind callback is not called for binaries built with
|
|
-Wl,-z,now or when LD_BIND_NOW=1 is used, nor the PLT tracking callbacks
|
|
(plt_enter and plt_exit) since this would change the expected
|
|
program semantics (where no PLT is expected) and would have performance
|
|
implications (such as for BZ#15533).
|
|
|
|
LAV_CURRENT is also bumped to indicate the audit ABI change (where
|
|
la_symbind flags are set by the loader to indicate no possible PLT
|
|
trace).
|
|
|
|
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.
