loader: Allocate trampoline as EfiLoaderCode, not Data

2026-07-21T21:23:11Z

Firmware on a test machine applied NX to non-code allocations, which resulted in a fault when jumping to the trampoline. Reviewed by: kib Tested by: Jim Huang Chen Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D58383

stand: Recognize SHT_INIT_ARRAY sections as constructor sections

2026-07-15T14:58:32Z

Pass such a section to the kernel using modinfo, otherwise link_elf.c won't execute constructors for the file. This is required for KASAN, otherwise redzones for global buffers are not poisoned during boot.

loader: Fix indentation mistakes

2026-07-13T20:23:31Z

Somehow, I wound up with space indents rather than tab indents, so fix this. Sponsored by: Netflix

loader: Add forgotten xz.c and zstdfs.c

2026-07-12T03:53:29Z

These were overlooked when I added compression support. Fixes: 86d719ae68aa ("loader: Add xzfs, like gzipfs but with xz.") Fixes: c61ee49cd06a ("loader: zstd based filesystem, zstdfs like gzipfs") Sponsored by: Netflix

loader: Add xzfs support by defualt to BIOS and EFI loaders

2026-07-11T19:28:47Z

For the BIOS, add xzfs support. This is a tiny increase in the loader size, but allows us to fetch compressed files from any of the filesystems we support, including over the network. For EFI, also add gzipfs and bzip2fs support we well. The increment for these files is tiny. Sponsored by: Netflix

loader: Add xzfs, like gzipfs but with xz.

2026-07-11T19:28:47Z

This is just like gzipfs or bzipfs, except done with the newer xz program. This is off by default for the moment. Sponsored by: Netflix

loader.efi: Add xz decompression

We can now decompress .xz compressed memory disks, like FreeBSD-15.1-RELEASE-amd64-disc1.iso.xz Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D58073

loader: Add two new build knobs for x86 BIOS loaders

2026-07-10T04:13:07Z

We have two sets of BIOS loaders: One that lives in stand/i386 and one that lives in stand/userboot. Add knows to turn these on/off, with the default being on. These often aren't needed when creating a minimal UEFI system, so add knobs to turn them off. Given light-weight VMs have created a new use cases for these loaders, there's no plans at all to eliminate them. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D58072
