These are the style points that I'd like to try and maintain in our lua
scripts:
- Parentheses around conditionals
- Trailing semicolons, except on block terminators
- s:method(...) instead of string.method(s, ...) where applicable
There's likely more, but that'll get hammered out as we continue.
Prompt for GELI passphrase when geom_eli_passphrase_prompt has been set to
"YES" in loader.conf(5).
This entailed breaking out the password prompt into its own function that
can be reused between the password compare bits and this prompt that simply
takes the entered password and passes it along in the environment as
kern.geom.eli.passphrase.
I've also added a TODO to re-evaluate later if we want the "password
masking" -- it is currently not functional, so one still can't observe the
length of the password typed at the prompt.
This is the procedure that config.loadkernel tries to go through, but
reloading kernel config didn't use this function. Amend config.loadkernel to
take an optional other_kernel.
While here, be a little more verbose ("Trying to load kernel") so that it's
easy to follow where we've gone wrong.
1.) Instead of string.function(s, ...), use s:function(...)
2.) Don't try to concatenate `res`, it was just tested to be nil
3.) Note that "Loading configuration" is configured modules, and be a little
more precise in mentioning what failed ("loading of one or more modules")
An empty module_path to start with isn't ideal, but if all modules are
contained within a kernel directory (which is what we just tested) then it
isn't strictly an error. Don't assume that module_path has a value already.
When we fail to load the kernel, printing the result (which is guaranteed to
be nil) is not intended; print the name of the kernel.
autoboot_delay=NO is documented to wait for input and *not* autoboot, which
is the exact opposite of the current behavior.
Additionally, autoboot_delay=-1 is documented to disallow the user from
interrupting the boot (i.e. autoboot immediately), which was not previously
honored.
This also fixes the case insensitive comparison to be truly case
insensitive. This is kind of nit-picky, but the previous version would only
accept "no" and "NO".
Don't move this into config.reload because we may want to force reloads if
/boot changes out from under us later.
As a caution: changing kernels in lualoader at the moment might not be
loading all of your modules (in my testing, at least) from loader.conf(5).
This is a known problem.
Detect ancient GCC specifically, rather than using target architecture as a
crude heuristic.
Side note: compilers should really ignore -Wno- and -Wno-error= flags they
don't recognize. Seems like modern compilers produce warnings instead of
errors. Though, with -Werror they turn into errors. Clang's error can be
disabled with -Wno-error=unknown-warning-option, but GCC doesn't seem to
have a named method to disable the specific warning.

Defaulting to CK_MD_RMO has the unfortunate side effect of generating
memory barriers that are useless on those arches, and the even more
unfortunate side effect of generating lfence/sfence/mfence on i386, even
if older CPUs don't support it.
This should fix the panic reported when using IPFW on a Pentium 3.
Note that mfence and sfence might still be used in a few case, but that
shouldn't happen in FreeBSD right now, and should be fixed upstream first.

Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."
This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.

The Pine64 root filesystem was incorrectly created directly on the MBR
partition. This can cause the loader to get confused when loading the
kernel from this filesystem.
The loader will see this as a small partition meaning later checks to
ensure it doesn't read past the end of the disk incorrectly report a
failure. This seems to work mostly by accident with the released images as
they are smaller than the reported size, however after growfs has run the
image may no longer boot.

ffs_sbget() may return a superblock buffer even if it fails, so the
caller must be prepared to free it in this case. Moreover, when tasting
alternate superblock locations in a loop, ffs_sbget()'s readfunc
callback must free the previously allocated buffer.

EXPORT_SYMS can be set to YES, NO, a list of symbols to export from a
module, or to a filename containing such a list. For the case that it
is set to a symbol list, replace spaces in the list with newlines, so
the created file is in the format expected by kmod_syms.awk.

Many licenses on Linuxolator files contained small variations from the
standard FreeBSD license text. To avoid license proliferation switch to
the standard 2-clause FreeBSD license for those files where I have
permission from each of the listed copyright holders. Additional files
waiting on permission from others are listed in review D14210.

This is a pre-cursor to boot environment support in lualoader. Create a new
menu item type, "carousel_entry", that generally provides a callback to get
the list of items, a carousel_id for storing the current value, and the
standard name/func functions that an entry has.
The difference between this and a normal menu item, functionally, is that
selecting a carousel item will automatically rotate through available items
and wrap back at the beginning when the list is exhausted.
The 'name' function takes the choice index, current choice, and the list of
choices as parameters so that the menu item can decorate the name freely as
desired.
The 'func' function takes the current choice as a parameter, so it can act
accordingly.
The kernel menu item has been rewritten to use the carousel_entry type as
both an example and initial test of its functionality before it is used for
boot environment options.
