ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Fix interactions of initial-exec TLS model and dlopen (1) If an initial-exec relocation was used for a non-local symbol (i.e. the definition of the symbol is in a different DSO), the computation of the static TLS offset used the wrong DSO. This would effectively mean the wrong address was computed (PR toolchain/50277, PR pkg/57445). Fix this by forcing the computation of the correct DSO (the one defining the symbol). This code uses __UNCONST to avoid the vast interface changes for this special case. (2) If symbols from a DSO loaded via dlopen are used with both global-dynamic/local-dynamic and initial-exec relocations AND a initial-exec relocation was resolved first in a thread, a split brain situation could exist where the dynamic relocations would use one memory block (separate allocation) and the initial-exec relocations the static per-thread TLS space. (3) If the initial-exec relocation in (2) is seen after any thread has already used a GD/LD allocation, bail out. Since IE relocations are used only in the GOT, this will prevent the dlopen. This is a bit more aggressive than necessary, but a full blown reference counting doesn't seem to be justified.

Pull up following revision(s) (requested by thorpej in ticket #758): libexec/ld.elf_so/map_object.c: revision 1.61 libexec/ld.elf_so/headers.c: revision 1.68 libexec/ld.elf_so/rtld.c: revision 1.203 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. XXX pullup-9

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. 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.
make sure we set LIBISPRIVATE.
fixes build issues reported by moof.

Coverity CID 2749: Fix another double free. Instead of removing that last free() call, change the allocation policy to leave the responsibility for allocation/freeing the pathname to _rtld_map_object(), instead of having the caller allocate it and _rtld_map_object() free it. This simplifies the code a lot and it is more efficient.

Rearrange _rtld_map_object() a little, so that we don't have to have the first page of the object double-mapped. Not that it matters much, but someone was whinging about it. While I'm at it, nuke obj->phdr and obj->phsize; they're unused.

Change the munmap() of the text-data gap to mprotect(PROT_NONE). This avoids having scattered little mappings, although it's probably not the best way...

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.

Introduce a new flag, `isdynamic', which is used to remember whether the executable was of type ET_DYN. Use this instead of `mainprog' to determine whether we need to do base-relative fixups of the PLT. (This allows loading non-relocatable objects, should we desire to do that at some point...)

SIMPLEQ rototill: - implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n), this mirrors the functionality of SLIST_REMOVE() (the other singly-linked list type) and FreeBSD's STAILQ_REMOVE() - remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD(). this mirrors the functionality of SLIST_REMOVE_HEAD() (the other singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD() - remove notes about SIMPLEQ not supporting arbitrary element removal - use SIMPLEQ_FOREACH() instead of home-grown for loops - use SIMPLEQ_EMPTY() appropriately - use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly - reorder manual page; be consistent about how the types are listed - other minor cleanups

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).

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.
