The utils that are pledged checked HAVE_PLEDGE which was
bogus. OpenBSD defines __OpenBSD__, which you can check
for in ifdef.
This change makes nvmutil and spkmodem-recv *actually*
use pledge, when the utils are compiled on OpenBSD.

It will only be used on OpenBSD. Other operating
systems will behave in the same way.
Pledge is feature specific to OpenBSD that
restricts system operations, for security:

printf outputs to stdout, which is line buffered
by default.
Adding a -u option to disable buffering.
Exit when a non-support flag is given, but adhere
to current behaviour when no flag is given.

They do not need to be initialised zero, because
global variables are always zero by default,
unless set differently by the programmer.

print_char() is referenced last, so declare it last.

This is a good general practise, to catch errors.
Any errors found can then be handled in code.

Main should only be a skeletal structure.
Actual logic should always be handled externally.

Add the appropriate prototype.
Top-down function order is easier to read.

Imported from util/spkmodem_recv at coreboot
revision:
e70bc423f9a2e1d13827f2703efe1f9c72549f20
This is a client for spkmodem, to allow serial
console via PC speaker.
I've decided to import it in lbmk, because I
heavily modified it. The patches will be
applied next.

the return value was never used
|
|
the deleted patch (in this commit) was written to fix an
issue theoretically; it hasn't been fully tested, and some
people have reported strange issues since this patch was
merged - there is no proof that this patch causes them, but
removing this patch is the correct thing to do regardless

when nicholas added this, he removed the README because it's
going on libreboot.org instead. however, i merged a WIP version
of his page for now because i want to get the e6400 going in
libreboot sooner. so, temp-readding this README. will just
link to this on codeberg or something, from the lb docs
NOTE: I didn't write this README, hence author field set
in the commit. Nicholas wrote it, but I (Leah Rowe) am just
adding it. so, git author set to nicholas, not me
|
|
Adding it to lbmk for now as it is not yet in coreboot. If it is merged
into coreboot we can just reference the one there. The original README
will be incorporated into a new page on lbwww, so README.md just points
to a placeholder URL that should match the new page.

small nitpick, but i try to use openbsd style
since i like that style. upon further reading
of their style guidelines today, it was revealed
to me that for includes, they:
* sort sys/ includes alphabetically, at the top
* after sys/ includes, have an empty line
* includes for networking-related headers below that
* empty space below networking headers if there
* after that, have the rest of the includes, sorted
alphabetically
at least, that is my understanding. i have to admit,
it does look cleaner
not really that critical but why not do it?
|
|
At the end of each line is an errant space.
Fix that.
|

don't download it. keep it in lbmk.
libreboot moved to codeberg for git hosting,
and i didn't want to keep lugging around an
extra git repo just for one tiny project.

not just sloccount, but compiled binary size as
tested with tcc on an x86_64 host
|
|
i went too hard on the sloc reductions
a check inside a for loop could cause
incomplete reading of gbe images
revert that
|
|
also removed some unnecessary checks
fixed the check of pwrite's return value
(it should check for -1)
|
|
|
|
added a few that were more useful
deleted a few obnoxious ones
|
|
the byteswap() function is used for big endian host
compatibility, but it can also be used to swap words
in the stored mac address
