* Fix data race in setting function descriptors during lazy binding on hppa.John David Anglin2020-03-301-5/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This addresses an issue that is present mainly on SMP machines running threaded code. In a typical indirect call or PLT import stub, the target address is loaded first. Then the global pointer is loaded into the PIC register in the delay slot of a branch to the target address. During lazy binding, the target address is a trampoline which transfers to _dl_runtime_resolve(). _dl_runtime_resolve() uses the relocation offset stored in the global pointer and the linkage map stored in the trampoline to find the relocation. Then, the function descriptor is updated. In a multi-threaded application, it is possible for the global pointer to be updated between the load of the target address and the global pointer. When this happens, the relocation offset has been replaced by the new global pointer. The function pointer has probably been updated as well but there is no way to find the address of the function descriptor and to transfer to the target. So, _dl_runtime_resolve() typically crashes. HP-UX addressed this problem by adding an extra pc-relative branch to the trampoline. The descriptor is initially setup to point to the branch. The branch then transfers to the trampoline. This allowed the trampoline code to figure out which descriptor was being used without any modification to user code. I didn't use this approach as it is more complex and changes function pointer canonicalization. The order of loading the target address and global pointer in indirect calls was not consistent with the order used in import stubs. In particular, $$dyncall and some inline versions of it loaded the global pointer first. This was inconsistent with the global pointer being updated first in dl-machine.h. Assuming the accesses are ordered, we want elf_machine_fixup_plt() to store the global pointer first and calls to load it last. Then, the global pointer will be correct when the target function is entered. However, just to make things more fun, HP added support for out-of-order execution of accesses in PA 2.0. The accesses used by calls are weakly ordered. So, it's possibly under some circumstances that a function might be entered with the wrong global pointer. However, HP uses weakly ordered accesses in 64-bit HP-UX, so I assume that loading the global pointer in the delay slot of the branch must work consistently. The basic fix for the race is a combination of modifying user code to preserve the address of the function descriptor in register %r22 and setting the least-significant bit in the relocation offset. The latter was suggested by Carlos as a way to distinguish relocation offsets from global pointer values. Conventionally, %r22 is used as the address of the function descriptor in calls to $$dyncall. So, it wasn't hard to preserve the address in %r22. I have updated gcc trunk and gcc-9 branch to not clobber %r22 in $$dyncall and inline indirect calls. I have also modified the import stubs in binutils trunk and the 2.33 branch to preserve %r22. This required making the stubs one instruction longer but we save one relocation. I also modified binutils to align the .plt section on a 8-byte boundary. This allows descriptors to be updated atomically with a floting-point store. With these changes, _dl_runtime_resolve() can fallback to an alternate mechanism to find the relocation offset when it has been clobbered. There's just one additional instruction in the fast path. I tested the fallback function, _dl_fix_reloc_arg(), by changing the branch to always use the fallback. Old code still runs as it did before. Fixes bug 23296.

* elf: Unify symbol address run-time calculation [BZ #19818]Maciej W. Rozycki2018-04-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.
