The current implementation of __strtoul_internal seems to only pretend
to support hex and octal strings by detecting a preceding 0x or 0 and
marking base as 8 or 16. When it comes to the actual processing of the
string, it only considers numeric values within, thus breaking hex
values that may have [a-f] in them. Fixed with this commit.
It may sometimes be desirable to make the dynamic linker only pick up
libraries from the library path and rpath and not look at the
ld.so.cache that ldconfig generates. An example of such a use case is
the glibc testsuite where the dynamic linker must not be influenced by
any external paths or caches.
This change adds a new option --inhibit-ldcache that when used, tells
the dynamic linker to not use ld.so.cache even if it is available.
* elf/rtld.c (dl_main): If DL_DEBUG_UNUSED is enabled, turn off
lazy binding.
* elf/dl-lookup (_dl_lookup_symbol_x): If DL_DEBUG_UNUSED, ignore
undefined symbol errors.
* elf/rtlc.c (dl_main): Skip VDSO when checking for unused
DT_NEEDED entries.
* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Protect local
variables with appropriate CPP guards.
* sysdeps/sparc/sparc32/dl-trampoline.S: Propagate the stack_ptr from the
frame pointer, not the stack pointer. Correct layout comments. Fix test
on resulting framesize and the management of the outregs buffer for pltexit.
Preserve floating point return values across _dl_call_pltexit call.
* sysdeps/sparc/sparc64/dl-trampoline.S: Fix test on resulting
framesize and the management of the outregs buffer for pltexit.
Preserve floating point return values across _dl_call_pltexit
call.
* elf/sotruss-lib.c (la_sparc32_gnu_pltenter, la_sparc64_gnu_pltenter,
la_sparc32_gnu_pltexit, la_sparc64_gnu_pltexit): New functions.
(print_exit): Fix format string for return register value.
update_get_addr returns a link_map*, but the return expression
was of type char*. Fix by relying on gcc's void* arithmetic
extension and auto-conversion from void*.
We never seem to have hit this problem but way relative relocations
were skipped was wrong. There are relative relocations only in the
DT_REL/DT_RELA section. The elf_dynamic_do_##reloc function skipped
the entries in all calls, though.
