* Serial console menus for lua.Warner Losh2018-08-202-26/+0
| | | | | | | | | | | Remove a bunch of special cases for UEFI and serial consoles. We do want to do curses and menu things here. This makes us match what we do in FORTH, with the possible exception of boxes around menus. Differential Revision: https://reviews.freebsd.org/D16816 Notes: svn path=/head/; revision=338108

* lualoader: Add drawer-exported variables for default logodefsKyle Evans2018-08-191-2/+4
| | | | | | | | | | | Uncovered while writing the documentation from this, we previously explicitly fell back to orb or orbbw if an invalid or incompatible logodef was selected -- in contrast to branddefs, which have an exported variable that one can whip up a quick local.lua to override in a safe manner that works regardless of whether or not loader.conf(5) successfully loads.

* Turn back the clock just a little: make userboot.so always be 4thWarner Losh2018-08-191-0/+1
| | | | | | | | | | | | | | | | | Turns out there was a hidden dependency we hasn't counted upon. The host load /boot/userboot.so to boot the VMs it runs. This means that the change to lua meant suddently that nobody could run their older VMs because LUA wasn't in 10.0, last month's HardenedBSD, 11.2 or whatever. Even more than for the /boot/loader* binaries, we need a good coexistance strategy for this. While that's being designed and implemented, drop back to always 4th for userboot.so. This will fail safe in all but the most extreme environments (but lua-only hacks to .lua files won't be processes in VMs until we fix it).

| | | | | | | | | | | | | | After years in the making, lualoader is ready to make its debut. Both flavors of loader are still built by default, and may be installed as /boot/loader or /boot/loader.efi as appropriate either by manually creating hard links or using LOADER_DEFAULT_INTERP as documented in build(7).

| | | | | | | | | | | | | | | Compiling FreeBSD/i386 with modern GCC triggers warnings for various places that convert 64-bit EFI_ADDRs to pointers and vice versa. - Cast pointers to uintptr_t rather than to uint64_t when assigning to a 64-bit integer. - Cast 64-bit integers to uintptr_t before a cast to a pointer.

However, we already have support for partial reads in bcache, and there is no need to have duplication via preprocessor controls. Note that bioscd/biosdisk interface is assumed to perform IO in 512B blocks, so the only translation we have to do is 512 <-> native block size.

* stand: Use -Oz/-Os for all loader/stand builds.Warner Losh2018-08-151-1/+6
| | | | | | | | | | | | | | | | | | | | While we're not super size constrained, the x86 BIOS /boot/loader has to be less than about 520k-530k to be reliable. The LUA loader is at this size today. -Oz saves 15-20% on the size, keeping us safely small enough (comparable to where we were with the 4th loader). This will also help with sjg's work on bringing in bearssl, though we may again be looking for space in the LUA loader.

| | | | | | | | | | | | | | | | | | Create loader_{4th,lua,simp}{,.efi}. All of these are installed by default. Create LOADER_DEFAULT_INTERP to specify the default interpreter when no other is specified. LOADER_INTERP is the current interpreter language building. Turn building of lua on by default to match 4th. simploader is a simplified loader build w/o any interpreter language (but with a simple loader). This is the historic behavir you got with WITHOUT_FORTH. Make a hard link to the default loader. This has to be a hard link rather than the more desirable soft link because older zfsboot blocks don't support symlinks.

| | | | | | | | | | | | | | | | On a FreeNAS mini XL, with geli encrypted drives the loader crashed in geli_read(). When we iterate over the list of disks and allocate the zfsdsk structures we don’t zero out the gdev pointer. In one case that resulted in geli_read() (called on the bogus pointer) dividing by zero. Use calloc() to ensure the zfsdsk structure is always zeroed, so the pointer is initialised to NULL. As a side benefit it gets rid of one #ifdef LOADER_GELI_SUPPORT.

| | | | | | | | | | | | | | | | | | | | efi-autoresizecons is currently executed for every boot. If it fails, we risk failing the boot, and we really shouldn't do that unless we absolutely must. Not being able to locate GOP or UGA is not a significant enough failure to kill the boot. We always have the option to fall back to resizing ConOut to a higher text mode resolution (if available), so do that. This was detected by Doug [1] while attempting a bhyve + UEFI + PXE boot. This patch was effectively also submitted by Doug, but I expanded the comment he had originally sent me a little bit to indicate why this is an OK idea.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | number of sectors reported through the BIOS. Cylinders * heads * sectors may not necessarily be equal to the total number of sectors reported through int13h function 48h. An example of this is when a Mediasonic HD3-U2B PATA to USB enclosure with a 80 GB disk is attached. Loader hangs at line 506 of stand/i386/libi386/biosdisk.c while attempting to read sectors beyond the end of the disk, sector 156906855. I discovered that the Mediasonic enclosure was reporting the disk with 9767 cylinders, 255 heads, 63 sectors/track. That's 156906855 sectors. However camcontrol and Windows 10 both report report the disk having 156301488 sectors, not the calculated value. At line 280 biosdisk.c sets the sectors to the higher of either bd->bd_sectors or the total calculated at line 276 (156906855) instead of the lower and correct value of 156301488 reported by int 13h 48h. This was tested on all three of my Mediasonic HD3-U2B PATA to USB enclosures. Instead of using the higher of bd_sectors (returned by int13h) or the calculated value, this patch uses the lower and safer of the values.
