elf: Fix dynamic-link.h usage on rtld.c
|
||
|
|
||
|
The 4af6982e4c fix does not fully handle RTLD_BOOTSTRAP usage on
|
||
|
rtld.c due two issues:
|
||
|
|
||
|
1. RTLD_BOOTSTRAP is also used on dl-machine.h on various
|
||
|
architectures and it changes the semantics of various machine
|
||
|
relocation functions.
|
||
|
|
||
|
2. The elf_get_dynamic_info() change was done sideways, previously
|
||
|
to 490e6c62aa get-dynamic-info.h was included by the first
|
||
|
dynamic-link.h include *without* RTLD_BOOTSTRAP being defined.
|
||
|
It means that the code within elf_get_dynamic_info() that uses
|
||
|
RTLD_BOOTSTRAP is in fact unused.
|
||
|
|
||
|
To fix 1. this patch now includes dynamic-link.h only once with
|
||
|
RTLD_BOOTSTRAP defined. The ELF_DYNAMIC_RELOCATE call will now have
|
||
|
the relocation fnctions with the expected semantics for the loader.
|
||
|
|
||
|
And to fix 2. part of 4af6982e4c is reverted (the check argument
|
||
|
elf_get_dynamic_info() is not required) and the RTLD_BOOTSTRAP
|
||
|
pieces are removed.
|
||
|
|
||
|
To reorganize the includes the static TLS definition is moved to
|
||
|
its own header to avoid a circular dependency (it is defined on
|
||
|
dynamic-link.h and dl-machine.h requires it at same time other
|
||
|
dynamic-link.h definition requires dl-machine.h defitions).
|
||
|
|
||
|
Also ELF_MACHINE_NO_REL, ELF_MACHINE_NO_RELA, and ELF_MACHINE_PLT_REL
|
||
|
are moved to its own header. Only ancient ABIs need special values
|
||
|
(arm, i386, and mips), so a generic one is used as default.
|
||
|
|
||
|
The powerpc Elf64_FuncDesc is also moved to its own header, since
|
||
|
csu code required its definition (which would require either include
|
||
|
elf/ folder or add a full path with elf/).
|
||
|
|
||
|
Checked on x86_64, i686, aarch64, armhf, powerpc64, powerpc32,
|
||
|
and powerpc64le.
