This reduces the amount of noise in the Linux kernel config files
by only storing the differences from the stock configuration.
It adds a new makefile target 'linux.saveconfig' to convert the
build tree's .config file into config/linux-linuxboot.config.
The Librem Key is a custom device USB-based security token Nitrokey is
producing for Purism and among other things it has custom firmware
created for use with Heads. In particular, when a board is configured
with CONFIG_LIBREMKEY, this custom firmware allows Heads to use the
sealed TOTP secret to also send an HOTP authentication to the Librem
Key. If the HOTP code is successful, the Librem Key will blink a green
LED, if unsuccessful it will blink red, thereby informing the user that
Heads has been tampered with without requiring them to use a phone to
validate the TOTP secret.
Heads will still use and show the TOTP secret, in case the user wants to
validate both codes (in case the Librem Key was lost or is no longer
trusted). It will also show the result of the HOTP verification (but not
the code itself), even though the user should trust only what the Librem
Key displays, so the user can confirm that both the device and Heads are
in sync. If HOTP is enabled, Heads will maintain a new TPM counter
separate from the Heads TPM counter that will increment each time HOTP
codes are checked.
This change also modifies the routines that update TOTP so that if
the Librem Key executables are present it will also update HOTP codes
and synchronize them with a Librem Key.
This modifies the segment at 0x0 so that it contains enough of a fake
Extended BIOS Data Area at addresses 0x40e and 0x413 that Xen can
correctly locate its trampoline code.
Since custom Xen is no longer required, we can remove the module,
the patches and all of the references to it in the board definition
files.
The modules file had a few errors that prevented slang from being built.
First the src/elfobjs file needed to be created before make started.
Second it needed to be configured without external png, pcre and onig
libraries it doesn't need for this application.
The whiptail binary will allow us to create GUI menus from bash scripts.
It is included in the newt library, which depends on slang. To enable,
the board configuration file should add CONFIG_SLANG=y and CONFIG_NEWT=y
USB smart card readers are most full speed devices, and there is no
"rate-matching hubs" beneath the root hub on older (e.g. GM45) plat-
forms, which has companion OHCI or UHCI controllers and needs cor-
responding drivers to communicate with card readers directly plugged
into the motherboard, otherwise a discrete USB hub should be inserted
between the motherboard and the reader.
This time I make inserting linux modules for OHCI and UHCI controllable
with option CONFIG_LINUX_USB_COMPANION_CONTROLLER.
A linux config for x200 is added as an example.
Tested on my x200s and elitebook revolve 810g1.
This adds a `CONFIG_UROOT=y` option to allow the busybox
runtime to be replaced with the go u-root runtime.
You must have go 1.9 or newer for it to work.
It has been tested on the OCP winterfell and qemu nodes,
and it can be specified on the build command line as well.
Nothing from `heads/initrd` or any of the tools will be
linked into the cpio file. Only the kernel modules and the
go shell will be included.
Move board configuration into `boards/` instead of `config/`
Fix mistake in building kernel module tree before kernel was done.
Allow per-board initrd builds (#278)
Allow per-board configurations for things (#304)
This development branch builds a NERF firmware for the Dell R630
server. It does not use coreboot; instead it branches directly
from the vendor's PEI core into Linux and the Heads runtime
that is setup to be run as an EFI executable.
Each of the submodule configuration files defined a subset of the
cross compiler tools that it used and many were picking up the
system `ar`, `nm`, `strip, `ld`, etc. They all now use a `Makefile`
macro that defines the path to the proper cross compiler tools.
For ones that need the tools, but not the musl-libc gcc,
there is $(CROSS_TOOLS_NOCC) that is all of them without gcc.
This is for musl-libc itself, as well as xen and the Linux kernel.
Replace libuuid with util-linux libuuid (and libblkid,
although we are not using libblkid right now).
This also requires a much larger coreboot cbfs, which was
fixed as part of issue #154.
This addresses multiple issues:
* Issue #63: initrd is build fresh each time, so tracked files do not matter.
* Issue #144: build time configuration
* Issue #123: allows us to customize the startup experience
* Issue #122: manual start-xen will go away
* Issue #25: tpmtotp PCRs are updated after reading the secret
* Issue #16: insmod now meaures modules
Reduce the size of flashrom by commenting out most flash chips,
boards and programmers.
Wrapper script to make it easier to rewrite the ROM on the x230
using the flashrom layout.
Keep the entire 12 MB ROM for flashing.
The populate-lib program was buggy on some systems and could accidentally
introduce unwanted libraries into the initrd. The Makefile now uses the
modules' $(module_libraries) variable to select which libraries should be
installed into the initrd.
Kernel modules are now stripped and installed using a similar system.
This is a step towards unifying the server and laptop config (issue #139)
and also makes it possible to later remove the USB modules from the
normal boot path.
This merges pull request #99 by @blackwellops and removes
the ./bootstrap script since the musl-cross can be built as
part of the normal dependency tree.
Use --prefix="" to ensure that no destination paths are in libraries.
Use -fdebug-prefix-map to rewrite build path so that it does not
appear in the executables.
Use -gno-record-gcc-switches to ensure that the -fdebug-prefix-map
does not appear in the executables.
Change all of the builds to use $(MAKE) instead of the /usr/bin/make.
Download and build GNU make-4.2 if the wrong version is installed
on the system.
Re-invoke build/make-4.2/make with the target that was passed in once
the correct make has been built.
Pass in the --host argument to all of the various programs
that need to treat the configure scripts as cross compilation
targets.
This removes all dependencies on the host libc (issue #7)
and adds some tools to the initrd (cryptsetup #46).
This adds compilations modules for musl-libc and kernel-headers.
The entire initrd (busybox, cryptsetup, gpgv, kexec, etc) can be built
with the much smaller libc and it appears to work with chroot.
Library paths are not set correctly and files are installed into
heads/install to make them accessible to other modules. This prevents
the initrd from working without manual fixup; need to fix before
merging into master.
Build times have gone up since everything is being rebuilt more
often for some reason.
As part of issue #1, we should build all libraries and programs that we
deploy into the Heads initrd. This modifies the module configurations
for all of them to install into heads/install so that we can build
against them.
Add dmsetup, cryptsetup and veritysetup (issue #46).
Build gpgv 1.4 as a standalone tool (issue #23).
Modify populate-lib to use the install directory by setting
LD_LIBRARY_PATH (issue #35).
No patches are required to boot 4.9 as a coreboot payload,
unlike the 4.7 kernel that required a head_64.S patch.
The new kernel is about 40 KB larger than the 4.7; the
config might be shrinkable.
Close issue #61.
rename TARGET to BOARD (fix#55)
use .INTERMEDIATE trick to avoid building multiple times (fix#52)
Don't touch build/*/.config if we don't have to (fix#51)
This touches most of the module configurations since the
coreboot build process had to add a few new features.
The Linux kernel could make use of it as well if we need
separate x230/chell/qemu kernels, for instance.
