Raw Normal View History

This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.

Enable the i386 loader to load and run an amd64 kernel. If this puts things over floppy size limits, I can exclude it for release builds or something like that. Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64.

Separate out the ELF relocation code from the ELF loader, and add better relocation support for the amd64 and i386 platforms.

RISC-V boot1.efi and loader.efi support This implementation doesn't have any major deviations from the other EFI ports. I've copied the boilerplate from arm and arm64. I've tested this with the following boot flows: OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required, as the HSM extension is needed to bring them up explicitly. Because of this, using BBL as the SBI implementation will not be possible. Additionally, there are a few recent u-boot changes that are required as well, all of which will be present in the upcoming v2020.07 release.

This will allow to use disk image from file system to load and start the kernel. By mapping file, we create vdiskX device, the device will be listed by lsdev [-v] and can be accessed directly as ls vdisk0p1:/path or can be used as value for currdev variable. vdisk strategy function does not use bcache as we have bcache used with backing file. vdisk can be unmapped when all consumers have closed the open files. In first iteration we do not support the zfs images because zfs pools do keep the device open (there is no "zpool export" mechanism). Adding zfs support is relatively simple, we just need to run zfs disk probe after mapping is done. Differential Revision: https://reviews.freebsd.org/D19733

Add flua to the base system, install to /usr/libexec FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

Break out the interpreters (simple and forth) w/o ifdefs. This is akin to what Pedro Souza and Wojciech Koszek did in the lua GSoC with interp.h, interp_simple.c and changes to interp.c and interp_forth.c, but completely redone from scratch. This effectively restores the spirit of r326712 (my first attempt to bring in Pedro's and Wojciech's work) updated for new requirements that had silently broke their original work. This change also differs by using fixed function names instead of function pointers to simply things. Only one interpreter at a time may be compiled in. Also of note: we take a mutable string, pass it in via a const char * pointer into intrp_forth's interp_run(). We then cast away the const to pass into ficlExec since ficl would require extensive changes to properly const-poison. See Sections 6.5.2.5 and 6.7.3 of C11 standard noting it's only UB if you modify a const object through a non-const pointer, but not char [] -> const char * -> char * as here.

.include "${BOOTSRC}/veriexec.mk"
Create kernel module to parse Veriexec manifest based on envs The current approach of injecting manifest into mac_veriexec is to verify the integrity of it in userspace (veriexec (8)) and pass its entries into kernel using a char device (/dev/veriexec). This requires verifying root partition integrity in loader, for example by using memory disk and checking its hash. Otherwise if rootfs is compromised an attacker could inject their own data. This patch introduces an option to parse manifest in kernel based on envs. The loader sets manifest path and digest. EVENTHANDLER is used to launch the module right after the rootfs is mounted. It has to be done this way, since one might want to verify integrity of the init file. This means that manifest is required to be present on the root partition. Note that the envs have to be set right before boot to make sure that no one can spoof them.

Introduce a new option (BOOT_PROMPT_123) that lets enter the boot prompt only when typing the sequence "123" (opposite to the standard 'push any button' approach). That results useful when using serial lines sending garbage and leading to unwilling boot prompt appearence.

Optionally include the install command as found on Juniper products like EX and SRX. The install command uses pkgfs to extract a kernel, zero or more modules and a root file system from the specified package and boots the kernel. The name of the kernel, the list of modules and the name of the root file system can be specified by putting a file called "metatags in the package. The package to use is given by an URL. The schemes supported are tftp and file. For the file scheme, the disk is currently hardcoded but that should really look for the package on all devices and partititions.

Collapse zfsloader functionality back down into loader. We no longer really need a separate zfsloader. It was useful when we were first supporting ZFS and had limited ability to properly boot off of ZFS without the special boot loader. Now that the boot loader has matured, go the way loader.efi pioneered and just build one binary. Change the name of the loader to load in the secondary boot blocks to be just /boot/loader. Provide a symbolic link from zfsloader to loader so people who have not upgraded their boot blocks are not affected. This has the happy benefit of making coexistence easier as well (fewer binaries in the matrix).

Secondly, all nvlist details are moved to separate source file and restructured a bit. This is done to provide base support to add nvlist add/update feature in followup updates.

Numerous cleanups from the original GSoC project, including hacking libsa to allow lua to be built with only one change outside luaconf.h. Add the final bit of lua glue to bring in liblua and plug into the multiple interpreter framework, previously committed. Add LOADER_LUA option, currently off by default. Presently, this is an experimental option. One must opt-in to using this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been lightly tested, so keep a backup copy of your old loader handy.
