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.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.

Revert to version 1.55 of map_object.c. This reverts:

"really unmap the gap between the text and data rather than just removing
all access with mprotect().  the latter results in the kernel having to
keep track of that range separately since the permissions are different.
avoid calling mmap() with a size of zero."

As per toolchain/52054: src/libexec/ld.elf_so update breaks everything,
this commit is very broken for some people (but not others). chs mentioned
he has a fix, but best not to leave -current broken in the meantime.

Fixed handling of DT_SONAME:

	- add function to add name aliases for shared libraries loaded
	  XXX[1]: we don't add a name during load time, only when DT_SONAME
	  is present.
	- search already loaded objects in load_by_name for an already
	  loaded object that matches our name and return it.
	- add missing initialization and cleanup for obj->names
	  XXX[2]: should we make them SIMPLEQ?
	- Add XXX in rtld.c about getting the name of an object.

NB: This makes the jdk work again without resorting to a hack of putting
    the build path of libjvm.so into the run path (which is a security
    problem).

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.

the caller allocate it and _rtld_map_object() free it. This simplifies the
code a lot and it is more efficient.

Several small changes that shave 7-8% off the simple-exec-loop test:

* Rename _rtld_find_library() to _rtld_load_library().  It now calls
  _rtld_load_object() if necessary to actually load the object, rather
  than having the caller do it.  To do this, it also takes the `mode'
  argument that gets passed to _rtld_load_object().

* On a related note, remove _rtld_check_library(), and instead call
  _rtld_load_object() to instead try actually loading the object.  We
  save two extra namei's and a bunch of redundant work (almost
  literally the same code) this way.

* In _rtld_map_object(), mmap(2) the first page read-only, rather than
  read(2)ing it.

* In _rtld_symlook_obj(), compare the *second* character of the symbol
  name before calling strcmp().  (This first character is too
  frequently `_', and turns out to not be helpful, in libc.)

* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
  -- this also allows removing the `in_plt' argument to
  _rtld_symlook_list() and _rtld_symlook_obj().

Also:

* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
  the each object, instead use obj->mapsize as the upper bound.

Pull up revision 1.12 (requested by skrll):
  Add init/fini section support in crtbegin and crtend, and introduce
  support for DWARF2 exception handling.  Fixes PR#12865, PR#13488,
  PR#13489, and PR#13491.  Also fix ld.elf_so to deal appropriately.

Return an error when there are too many segments rather than abort()ing.
This way `ldd /usr/libexec/ld.elf_so' doesn't core dump.

switch back to using a file mapping for the initial mapping of a new object.
this allows the kernel to use PMAP_PREFER() to give us better alignment on
platforms that care.

Undo last change. While these macros are defined in exec_elf.h, they are
enclosed by `#ifdef _KERNEL'.

When allocating the entire address space of an object, map an anonymous
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.

The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.

This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

Mipsel changes to ELF ldd/ld.so:
  * don't abort() on NetBSD/pmax 1.1 elf binaries;
  * Assume 32-bit elf unless compiling for Alpha;
  * note bugs in ldd's README.

First cut at an ELF shared loader.  Originally from John Polstra's FreeBSD elf
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.).  This runs, but it's
in serious need of cleaning and/or a fair bit of reworking.  See the README
file for more information, and a list of things to do.
