PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
to debug/stack_chk_fail.c, debug/stack_chk_fail_local.c should be
removed. Since dummy __stack_chk_fail and __stack_chk_fail_local
symbols are used in ld.so, tst-_dl_addr_inside_object should be
linked with $(dummy-stack-chk-fail). Tested on x86-64 with
--enable-stack-protector=all and got
FAIL: elf/tst-env-setuid
FAIL: elf/tst-env-setuid-tunables
FAIL: stdlib/tst-secure-getenv
which are the same as without this patch.
* [BZ #21740]
* debug/Makefile (static-only-routines): Remove
stack_chk_fail_local.
* debug/stack_chk_fail_local.c: Removed.
* elf/Makefile (LDFLAGS-tst-_dl_addr_inside_object): New.
