christos | Create a new header lwp_private.h to contain _lwp_getprivate_fast, _lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that: 1. we don't need special hacks to hide them 2. we can include <lwp.h> where needed to get the necessary prototypes without redefining them locally.

joerg | branches: 1.75.2; 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.

joerg | 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.

joerg | Add basic support for indirect functions. It allows providing a public function symbol with an implementation choosen at run time. Refactor calls to functions by address in ld.elf_so to create temporary function descriptors on the stack, if the address is not leaked outside.
Limitations: - no support for initialising static storage with function pointers - no support for unnamed resolver functions

Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase. Now when the symbol is resolved, st_value + maprelocbase will equal 0 and the above check in _rtld_bind will fire and a call to NULL will be avoided.

| 25-Sep-2002 |
mycroft | Resolve the GOT before doing relocations. Then, when doing relocations, for symbols in the global part of the symbol table, use the updated GOT entry rather than doing a lookup. (This provides the same effect as `-z combreloc' on other platforms -- at most one lookup is done per symbol.)
Unfortunately, it is necessary to turn off lazy binding on MIPS. As the comment says:
* XXX DANGER WILL ROBINSON! * You might think this is stupid, as it intentionally * defeats lazy binding -- and you'd be right. * Unfortunately, for lazy binding to work right, we * need to a way to force the GOT slots used for * function pointers to be resolved immediately. This * is supposed to be done automatically by the linker, * by not outputting a PLT slot and setting st_value * to 0, but GNU ld does not do so reliably.

|
1.29 |
| 13-Sep-2002 |
mycroft | Put back the lazy binding. For some bizarre reason, the linker occasionally does not create a PLT entry for a symbol, so we test st_value!=0 to see whether we can do a PLT fixup.

mycroft | Snapshot of work to make MIPS ld.elf_so relocatable.
|
1.16 |
| 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which indicates whether we're relocating ld.elf_so itself. Use this in some places rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore dodebug is always true.)
|
1.15 |
| 06-Sep-2002 |
mycroft | 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...)

mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
1.12 |
| 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions: * _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On most platforms it just does a simple base-relative fixup; on SPARC it does nothing.) * _rtld_relocate_plt_object() does immediate binding for a PLT entry. The basic gist is that this saves a bit of time on SPARC (where the iteration through the pltrela table was gratuitous), and a little less time on all other platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64

mycroft | A few things: * Pass a symbol number to _rtld_find_symdef(), not a r_info. * Don't try to do a symbol lookup when we find an unsupported relocation; instead get the symbol name from the referencing object's strtab. * Add preliminary support for `-z combreloc'-style startup optimization on i386, `#ifdef COMBRELOC'.

1.4 |
| 14-Oct-2001 |
rafal | Fix how underfined weak symbols are treated -- before, ld.so would do nothing with them, rather than defaulting them to zero. This caused breakage with the drawf EH stuff and init/fini code when they weren't used by the caller (and hence the appropriate handlers were left undefined). Also fix an un- initialized variable in symbol.c that only MIPS MD code tripped over.

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.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

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! PR misc/57462
