2013-02-06Add a dummy memcpy(), needed when building ld.so with gcc3.Miod Vallat
2013-02-02Be sure to pass a NULL cleanup pointer to CSU.Miod Vallat
2013-01-31The code to use relative jumps in the GOT was completely broken, calculatingPhilip Guenther
the offset in the wrong direction, failing to take into account where in the relocation the jump would be, and not even using the right instructions in one case. Fortunately(?), the test of whether the offset was small enough had signed-vs-unsigned bugs too, so it was never used. ok miod@
2013-01-29refactor code a bit to actually store subjects in the subject objectMarc Espie
reformat for 8 spaces tab. okay millert@
2013-01-26Make sure to flush I$ over the plt in case of non-lazy relocation as well.Miod Vallat
2013-01-26Forgot to remove one line in 1.2, in turn caused div() from libc to fail ifMiod Vallat
invoked with lazy binding.
2013-01-23bits for an m68k ELF ld.so, to be used soon. Lazy resolver wrapper borrowed fromMiod Vallat
NetBSD.
2013-01-23Cache flush .plt after updating its pointers to .got during the initialMiod Vallat
object relocation, if loaded at a different address than the one it was compiled for; unsurprisingly fixes some spurious crashes.
2013-01-21Use jmp, not jsr, to jump through registers. Doh!Miod Vallat
This makes lazy binding work, so don't disable it anymore.
2013-01-21Correctly define RELOC_JMP_SLOT on m88k. While there, remove the old sparcMiod Vallat
wrong RELOC_JMP_SLOT define workaround.
2013-01-20A first cut at ld.so bits for m88k. Lazy binding is currently disabled as itMiod Vallat
does not work beyond the first few lazy resolver calls. But that's already enough to run simple binaries.
2013-01-19Do not divide by zero in _dl_findhint() if there is a valid hints file butMiod Vallat
no buckets in it (could happen if the administrator reruns ldconfig with bogus paths). ok matthew@ kurt@ drahn
2013-01-14Do not bogusly attempt to mprotect ld.so's .rodata area RW at bootstrapMiod Vallat
time: the logic is wrong, and there are no relocations to apply to .rodata anyway. ok jsing@ kettenis@
2013-01-13Fix warnings.Federico G. Schwindt
millert@ ok.
2013-01-13Correctly process RELOC_DIR32 while relocating ld.so itself; this allowMiod Vallat
global data initializers to work as intended. ok drahn kettenis@
2013-01-11Proper bounds checking for DT_xxx values in _dl_boot_bind(). Turned out to beMiod Vallat
harmless because we have full control over the array being processed, and none of the values we set up may trigger the bug; yet this may change in the future. ok drahn matthew@

2012-12-22Zero %r0 before transferring control to the main program, to indicate thatMark Kettenis

2012-11-01Zero v0 before transferring control to the main program to indicate thatMark Kettenis
the main program should not reguster a cleanup handler with atexit(3). This will allow us to add the cleanup handler registration code to crt0.c and have ld.so pass its cleanup handler to the main program in the future. While there, also zero ra to mark the last stack frame as demanded by the ELF ABI. ok kurt@, miod@

2012-08-31Compile ld.so with debug info. This will not only help people hacking onMark Kettenis
ld.so itself, but also make it easier to debug code that uses dlopen(3). ok deraadt@, matthew@

2012-08-28Add __guard_local as a hidden symbol to ld.so, kernel, and everyMatthew Dempsky
executable and DSO (via crtbegin.c/crtbeginS.c). Not used yet, but needed before GCC can start emitting -fstack-protector code that uses them instead of __guard.
2012-08-22Change ld.so and libc to use .openbsd.randomdata on ELF platforms forMatthew Dempsky
initializing their __guard values. For the time being, we're leaving libc's constructor method as a backup to make sure __guard actually gets initialized and to emit syslog warnings when it's not. Not really an ABI change, so no shlib bump... "hold on to your butts" ok deraadt, kettenis
2012-08-20Add support for .openbsd.randomdata sections and PT_OPENBSD_RANDOMIZEMatthew Dempsky
segments to the kernel, ld (2.15), and ld.so. Tested on alpha, amd64, i386, macppc, and sparc64 (thanks naddy, mpi, and okan!). Idea discussed for some time; committing now for further testing. ok deraadt
2012-08-17Fix mips64 and powerpc's ld.so syscall implementations by addingMatthew Dempsky
"memory" to the list of clobbered registers for all syscalls that accept a pointer. This prevents GCC from optimizing away memory loads and stores that otherwise appear unused in a function. Issue noted and identified by miod; fix by me. ok miod, mpi
