* Disable PIE for powerpc bootloaders.Marcin Wojtas2021-02-244-0/+8
| | | | | | | | | | | | | Bootloaders for powerpc are not built as position independent code. Since bsd.prog.mk is used for building, when PIE is enabled, the PIE flags are added and that causes the build to fail. Adding MK_PIE=no stops bsd.prog.mk from adding PIE specific flags.

| | | | | | | | | | | | | | | | | | | Currently, the only thing that prevents a functioning 64-bit FICL build is a few integer types that were intended to be fixed-width. Changing them to C99 integer types allows building a functioning 64-bit FICL. While this isn't applicable to the default settings of any in-tree loaders, it is necessary for a future Petitboot loader, due to the requirement that it be compiled as a 64-bit program.

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-081-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.

* [PowerPC] Fix LLD10 linking of ofw loader on ppcBrandon Bergren2020-02-251-1/+5
| | | | | | | | | | | | | | | | | | | | | Before this change, LLD10 was creating several extra PT_LOAD sections, which OFW does not understand. Like we do for the kernel already, specify the program headers manually. Additionally, to work around a crash in our base ld.bfd, we need to actually assign something to the output section. LLD does not need this. One side effect of this change is the removal of the GNU_STACK header. This is more correct, since we are using a statically-allocated stack and RWX mappings across the board this early in boot.

* powerpc/loader: Install ubldr without strippingJustin Hibbits2019-09-201-0/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Install's strip capability, by way of strip(1), doesn't seem to work correctly on msdosfs, and instead ends up truncating the resulting binary to 0-length. As a workaround, don't strip ubldr(8). This fixes installworld on Book-E ubldr-based platforms, which prior to this would need to manually install ubldr separately after installworld, in order to have a functional ubldr. The same thing could be done on PowerNV platforms that use msdosfs /boot volumes, since loader and loader.kboot, etc, all get truncated to 0 on install. However, PowerNV does not use loader, instead loading from petitboot, so it's not really necessary at this time.

* [PPC64] Implement CASLeandro Lupori2019-07-313-1/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Guest PPC OSs running under a hypervisor may communicate the features they support, in order for the hypervisor to expose a virtualized machine in the way the client (guest OS) expects (see LoPAPR 1.1 - B.6.2.3). This is done by calling the "/ibm,client-architecture-support" (CAS) method, informing supported features in option vectors. Until now, FreeBSD wasn't using CAS, but instead relied on hypervisor/QEMU's defaults. The problem is that, without CAS, it is very inconvenient to run POWER9 VMs on a POWER9 host running with radix enabled. This happens because, in this case, the QEMU default is to present the guest OS a dual MMU (HPT/RPT), instead of presenting a regular HPT MMU, as FreeBSD expects, resulting in an early panic. The known workarounds required either changing the host to disable radix or passing a flag to QEMU to run in a POWER8 compatible mode. With CAS, FreeBSD is now able to communicate that it wants an HPT MMU, independent of the host setup, which now makes FreeBSD work on POWER9/pseries, with KVM enabled and without hugepages (support added in a previous commit). As CAS is invoked through OpenFirmware's call-method interface, it needs to be performed early, when OpenFirmware is still operational. Besides, now that FDT is the default way to inspect the device tree on PPC, OFW call-method feature will be unavailable by default, when control is passed to the kernel. Because of this, the call to CAS is being performed at the loader, instead of at the kernel. To avoid regressions with old platforms, this change uses CAS only on POWER8/POWER9.

* stand: refactor overlay loading a little bitKyle Evans2019-04-112-0/+12
| | | | | | | | | | | | | | | | | | | | | It was pointed out that manually loading a .dtb to be used rather than relying on platform-specific method for loading .dtb will result in overlays not being applied. This was true because overlay loading was hacked into fdt_platform_load_dtb, rather than done in a way more independent from how the .dtb is loaded. Instead, push overlay loading (for now) out into an fdt_platform_load_overlays. This method easily allows ubldr to pull in any fdt_overlays specified in the ub env, and omits overlay-checking on platforms where they're not tested and/or not desired (e.g. powerpc). If we eventually stop caring about fdt_overlays from ubenv (if we ever cared), this method should get chopped out in favor of just calling fdt_load_dtb_overlays() directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PowerPC Apple hardware, and likely all Open Firmware systems. The loader would allocate memory for its heap at whatever address Open Firmware gave it, which would in general be the lowest unallocated address, usually starting a page or two above 0. As the kernel is linked at 1 MB, and loader insists on running the kernel at its link address, any heap larger than 1 MB would overlap the kernel, causing loader memory allocations to corrupt the kernel and vice versa. Although r328806 made this problem much worse by increasing the heap size to 8 MB, causing 88% of the loader heap to overlap with the kernel, the problem has always existed. The old heap size was 1 MB and, unless that started exactly at zero, which would cause other problems, some number of pages of the loader heap still overlapped with the kernel. This patch solves the issue in two ways and cleans up some related code: - Moves the loader heap inside of the loader. This guarantees that the heap will be contiguous with the loader and simplifies the heap allocation code at no cost, since the heap lives in BSS. - Moves the loader, previously at 28 MB and dangerously close to the kernel it loads, a bit higher to 44 MB. This has the effect of breaking loader on non-embedded PPC machines with < 48 MB of RAM, but we did not support those anyway. The fundamental problem is that the way loader loads ELF files is incredibly fragile, but that can't be fixed without fundamental architectural changes.
