riastradh | ld.elf_so: Implement RELR relocations.
The SHT_RELR-type .relr.dyn section, pointed to by the DT_RELR
dynamic tag, holds compressed R_*_RELATIVE-type relocations,
substantially reducing the disk space occupied by many programs.
This commit adds support in ld.elf_so for relocating dynamically
linked executables with RELR relocations.

riastradh | ld.elf_so: Teach this to handle MIPS PIE rtld debug data.
Adapt t_rtld_r_debug to handle the two MIPS cases too.
XXX t_rtld_r_debug should be tested both as PIE and non-PIE to
exercise both cases.
Context:
The value of a DT_DEBUG .dynamic entry is initialized at load-time,
by ld.elf_so, to a pointer to a data structure set up by ld.elf_so
describing the shared objects loaded by the executable, so debuggers
can find them from, e.g., core dumps. None of this is really
documented anywhere that I can find. Best reference is this post on
the gdb mailing list from a quarter century ago saying there's no
real documentation:
https://web.archive.org/web/20250414021320/https://sourceware.org/pipermail/gdb/2000-April/004509.html
However, on MIPS, the .dynamic section is mapped read-only, so
ld.elf_so can't properly modify it (I imagine technically it could
with some mprotect shenanigans but that's not how it's done on MIPS).
Instead, the linker reserves a location in read/write memory and uses
a DT_MIPS_RLD_MAP entry with a pointer to that location.
However, in position-independent executables, the .dynamic entry
can't have an absolute pointer to that location because it's not
known up front. Instead, the the linker uses a DT_MIPS_RLD_MAP_REL
entry with the relative offset to that location from the Elf_Dyn
entry itself.
I would add a reference for this but it's basically a matter of UTSL
plus some oblique mentions on the web and mailing list discussions:

thorpej | PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.
Fixes PR toolchain/55043.

Applied latest patch.
|
| 1.40 |
| 09-Mar-2011 |
joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
grab these values via reach-over more easily.
some fixes for PR#40170:
- set NATIVE=yes in the environment for genscripts.sh
- set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
- set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
- get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)
- convert a.out, elf32 and elf64 support into convience libraries and
link them right ones in. if elf_ldd() fails on 64 bit platforms,
try elf32_ldd() before aout_ldd().
now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
*and _LP64. necessary for 32/64 bit combo ldd support.
- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.
make sure we set LIBISPRIVATE.
fixes build issues reported by moof.

Remove a debug assert that does not hold for PIE (e.g. phdr = 0x40, but
obj has not been mapped at 0, so obj->phdr is 0x100040).

Add special handling needed for OLO10 relocations.

Remove old assert that only two segments exist. The rest of the code has
been changed to cope with more and at least Go actively creates them.
Adjust the mapping size computation to use the maximum and not depend on
PT_LOAD segments to be in order.

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.
Fixes PR toolchain/55043.
