| | | | | | | | | | | | | | | | | | | | | | | | weren't needed, and their existance interfered with things in subtle ways. One of these subtle ways was that malloc could be different based on what files were included when (even within the same .c file, it turns out). Move to a single malloc implementation as well by adding the calls to setheap() to gptboot.c and zfsboot.c. Once upon a time, these boot loaders strove to not use libstand. However, with the proliferation of features, that striving is too hard for too little gain and lead to stupid mistakes. This fixes the GELI-enabled (but not even using) boot environment. The geli routines were calling libstand malloc but zfsboot.c and gptboot.c were using the mini libstand malloc, so this failed when we tried to probe for GELI partitions. Subtle changes in build order when moving to self-contained stand build in r326593 toggled what it used from one type to another due to odd nesting of the zfs implementation code that differed subtly between zfsloader and zfsboot.

* Cargo cut a fix for the regressions r326585 caused.Warner Losh2017-12-141-3/+3
| | | | | | | | | | | | | | | | We need to include ficl.h after the standard includes, rather than before them. It changes the generated code in ways that haven't been completely analyized. This restores the old code generation (as verified by md5 changing back for zfsloader). This should restore GPT + ZFS and GPT + ZFS + GELI booting that was broken in r326585 (or would have been if r326584 hadn't broken the build).

* Save and restore r9 register in arm ubldr. In old gcc 4.2, r9 was a callee-Ian Lepore2017-12-101-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | saved register, but in arm EABI it may be either callee-saved or dedicated to some special purpose (such as a TLS pointer). It appears clang does not treat it as a callee-saved register (instead using it as another work register, similar to r12). Another important side effect of these changes is that saving an extra register in the push/pop statements keeps the stack aligned to an 8-byte boundary during the self_reloc() call, as it always should have been. As stated in the PR... Essentially the important caller-saved registers are pushed (r0, r1, r9, lr) before the relocation call, and popped after. Then r8/r9 are saved as usual for the syscall trampoline, and lr is stored in r8 (now free) as a callee-saved value before calling into `main`. The call to `main` can no longer be a tail call because we must restore r9 especially after main returns (although since we have used r8 to hold lr we must also restore this).

| | | | | | | | | | | | | | | Building with the standard system headers isn't a perfect match to the stand environment. Instead, copy over the files we know are safe to use and constrain what else is used. We use -nostdinc to achieve this. This also fixes issues with building 32-bit libraries on amd64 sometimes pulling in the wrong cpufunc.h giving an error now that we stop on errors.
