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.

loader: network read rework The current read from network is working from up to down - we have some protocol needing the data from the network, so we build the buffer space for that protocol, add the extra space for headers and pass this buffer down to be filled by nif get call in hope, we have guessed the incoming packet size right. Amazingly enough this approach mostly does work, but not always... So, this update does work from down to up - we allocate buffer (based on MTU or frame size info), fill it up, and pass on for upper layers. The obvious problem is that when we should free the buffer - if at all. In the current implementation the upper layer will free the packet on error or when the packet is no longer needed. While working on the issue, the additional issue did pop up - the bios implementation does not have generic get/put interface but is using pxe udpsend/udpreceive instead. So the udp calls are gone and undi interface is implemented instead. Which in turn means slight other changes as we do not need to have duplicated pxe implementation and can just use dev_net. To align packet content, the actual read from nic is using shifted buffer by ETHER_ALIGN (2). Reviewed by: bapt Differential Revision: https://reviews.freebsd.org/D10232

In case of BIOS, the chain will read the boot block to address 0000:7c00 and jumps on it. In case of UEFI, the chain command is to be used with efi application, typically stored in EFI System Partition. The update also does add simple menu entry, if the variable chain_disk is set.

Implement boot-time encryption key passing (keybuf) This patch adds a general mechanism for providing encryption keys to the kernel from the boot loader. This is intended to enable GELI support at boot time, providing a better mechanism for passing keys to the kernel than environment variables. It is designed to be extensible to other applications, and can easily handle multiple encrypted volumes with different keys. This mechanism is currently used by the pending GELI EFI work. Additionally, this mechanism can potentially be used to interface with GRUB, opening up options for coreboot+GRUB configurations with completely encrypted disks. Another benefit over the existing system is that it does not require re-deriving the user key from the password at each boot stage. Most of this patch was written by Eric McCorkle. It was extended by Allan Jude with a number of minor enhancements and extending the keybuf feature into boot2. GELI user keys are now derived once, in boot2, then passed to the loader, which reuses the key, then passes it to the kernel, where the GELI module destroys the keybuf after decrypting the volumes.

This eliminates the need to set the LOADER_ZFS_SUPPORT variable in order to get a ZFS enabled loader. Note however, that you must reinstall your bootcode (zfsboot/gptzfsboot) in order for the boot process to use the new loader. New installations will no longer be required to build a ZFS enabled loader for a working ZFS boot system.

${LOADER}: ${LOADER}.bin ${BTXLDR} ${BTXKERN}
Revert previous untested revision. The i386 loader consists of three parts: At the front is btxldr, in the middle is BTX itself (our mini-kernel), and then the 'client' (loader.bin) which is the actual loader itself. boot2 just executes a raw ELF or a.out binary with the only setup provided being that a bootinfo structure is passed on the stack. Now, since loader.bin is a BTX client, the loader needs to be able to locate a BTX kernel for the client to execute in the context. Thus, just like pxelder, btxldr uses the a.out header on the loader binary to find the BTX kernel stored in the loader and set it up. It does _not_ just reuse the BTX kernel that boot2 invoked it with. This is because it can't assume that it will _have_ a "spare" BTX kernel lying around. For example, when cdboot loads the loader there isn't an existing BTX kernel. In fact, cdboot will only work with an a.out loader as well since it also "borrows" the BTX kernel in the loader binary (which it finds by parsing the a.out header) just as pxeldr does. The only difference between cdboot and pxeldr is where they get /boot/loader from. If we wanted to make /boot/loader be an actual ELF binary we would need to change the following utilites to handle that (and they all have to be able to handle locating the BTX kernel inside of an ELF binary somehow): - btxldr - pxeldr - cdboot If we didn't want to require a flag day but make the transition smooth then we need to be able to support both a.out and ELF versions of /boot/loader which isn't exactly trivial since all three of these utilities are written in assembly.

Create a seperate ZFS enabled loader. This adds zfsloader which will be called by zfsboot/gptzfsboot code rather than the tradional loader. This eliminates the need to set the LOADER_ZFS_SUPPORT variable in order to get a ZFS enabled loader. Note however, that you must reinstall your bootcode (zfsboot/gptzfsboot) in order for the boot process to use the new loader. New installations will no longer be required to build a ZFS enabled loader for a working ZFS boot system. Installing zfsboot/gptzfsboot is sufficient for acknowledging the use of CDDL code and therefore the ZFS enabled loader. Based on a previous patch from jhb@ Reviewed by: jhb@ MFC after: 2 weeks

-b ${BTXKERN} ${LOADER}.bin
Initial integration of the i386 bootloader and BTX. - Discard large amounts of BIOS-related code in favour of the more compact BTX vm86 interface. - Build the loader module as ELF, although the resulting object is a.out, make gensetdefs 32/64-bit sensitive and use a single copy of it. - Throw away installboot, as it's no longer required. - Use direct bcopy operations in the i386_copy module, as BTX maps the first 16M of memory. Check operations against the detected size of actual memory.
