2018-04-01LLVM 6.0.0's -Wextra warnings now complain if you do arithmetics on NULLPatrick Wildt
pointers. Since binutils 2.17 is compiled with -Werror, this breaks the build. Change the function to return -1 as suggested by the comment in said function. ok kettenis@

2018-01-04Add ARM EABI aliases and remove functions that are also provided by our libc.Mark Kettenis
This allows linking code compiled by clang with the gcc compiler driver and makes sure we always use the softfloat implementation in libc. The libc softfloat implementation is preferred over the one in libgcc as it implements rounding modes and floating point exceptions. ok patrick@

instructions to have side effects so the optimizer does not reorder them across fnstcw/fldcw sequences. Fixes a bug seen in sqlite3 on i386. ok kettenis@

Makes gas work when compiled with clang. ok patrick@, millert@
2017-11-21The compiler is generally free to allocate general purpose registers in whatevermortimer
order it chooses. Reasons for choosing one register before another usually incl ude compiled instruction size (avoidance of REX prefixes, etc.) or usage convent ions, but somehow haven't included security implications in the compiled bytecod e. Some bytecode is more useful in polymorphic ROP sequences than others, so it seems prudent to try to avoid that bytecode when possible. This patch moves EBX/RBX towards the end of the allocation preference for 32 and 64 bit general purpose registers. Some instructions using RBX/EBX/BX/BL as a de stination register end up with a ModR/M byte of C3 or CB, which is often useful in ROP gadgets. Because these gadgets often occur in the middle of functions, th ey exhibit somewhat higher diversity than some other C3/CB terminated gadgets. T his change removes about 3% of total gadgets from the kernel, but about 6% of un ique gadgets. There are other possible changes in this direction. BX/BL are obvious next targe ts for avoidance, and MM3/XMM3 may also be useful to try to avoid if possible. ok deraadt@

2017-11-04Revert recent changes to unbreak ports/net/sambaJeremie Courreges-Anglas
While it is not clear (to me) why that ports ends up with corrupted shared libs, reverting those changes fixes the issue and should allow us to close p2k17 more smoothly. Discussed with a bunch, ok ajacoutot@ guenther@
2017-10-31Make -zdefs and --no-undefined no-ops for now, to unblock ports devs at p2k17.Philip Guenther
We don't link libc into shared-libraries by default to avoid binding libraries to specific libc majors, so those options have always suffered false positives for us, but with the move of functions from libpthread to libc the problem has gotten even worse. A version-agnostic binding to libc would solve this better but it's on back-order behind the pony I requested. tweak and ok deraadt@

This is mostly needed by syspatch at the moment to be to be able to re-link in the same order as the original libraries were linked with by relying on the readelf(1) and without this .(s|S) assembly files were not getting a file directive.
