Sometimes, pacman will show messages about maintenance steps that you will need to perform with certain files (typically configurations) after the update. Also, you should check both the Parabola and Arch home pages to see if they mention any issues. If a new kernel is installed, you should also update to be able to use it (the currently running kernel will also be fine). It's generally good enough to update Parabola once every week, or maybe twice. As a rolling release distribution, it's a good idea never to leave your install too outdated; update regularly. This is simply because of the way the project works; old packages are deleted from the repositories quickly, once they are updated. A system that hasn't been updated for quite a while will mean potentially more reading of previous posts through the website, and more maintenance work. + +The Arch forum can also be useful, if others have the same issue as you (if you encounter issues, that is). The @emph{Parabola} IRC channel (#parabola on freenode) can also help you. + +Due to this and the volatile nature of Parabola/Arch, you should only update when you have at least a couple hours of spare time in case of issues that need to be resolved. You should never update, for example, if you need your system for an important event, like a presentation or sending an email to an important person before an allocated deadline, and so on. + +Relax - packages are well-tested regularly when new updates are made to the repositories. Separate 'testing' repositories exist for this exact reason.

Doing so will make the upcoming ROM modifications MUCH easier to perform and less risky! @uref{configuring_parabola.html,configuring_parabola.html} shows my own notes post-installation. Using these, you can get a basic system similar to the one that I chose for myself. You can also cherry pick useful notes and come up with your own system. Parabola is user-centric, which means that you are in control. For more information, read @uref{https://wiki.archlinux.org/index.php/The_Arch_Way,The Arch Way} (Parabola also follows it). + +@node Modify grubcfg inside the ROM +@section Modify grub.cfg inside the ROM +@anchor{#modify-grub.cfg-inside-the-rom} +(Re-)log in to your system, pressing C, so booting manually from GRUB (see above). You need to modify the ROM, so that Parabola can boot automatically with this configuration. @uref{grub_cbfs.html,grub_cbfs.html} shows you how. Follow that guide, using the configuration details below. If you go for option 2 (re-flash), promise to do this on grubtest.cfg first! We can't emphasise this enough. This is to reduce the possibility of bricking your device! + +I will go for the re-flash option here. Firstly, cd to the libreboot_util/cbfstool/@{armv7l i686 x86_64@} directory. Dump the current firmware - where @emph{libreboot.rom} is an example: make sure to adapt:@* # @strong{flashrom -p internal -r libreboot.rom}@* If flashrom complains about multiple flash chips detected, add a @emph{-c} option at the end, with the name of your chosen chip is quotes.@* You can check if everything is in there (@emph{grub.cfg} and @emph{grubtest.cfg} would be really nice):@* $ @strong{./cbfstool libreboot.rom print}@* Extract grubtest.cfg:@* $ @strong{./cbfstool libreboot.rom extract -n grubtest.cfg -f grubtest.cfg}@* And modify:@* $ @strong{nano grubtest.cfg} + +In grubtest.cfg, inside the 'Load Operating System' menu entry, change the contents to: + +@verbatim +cryptomount -a +set root='lvm/matrix-rootvol' +linux /boot/vmlinuz-linux-libre-lts root=/dev/matrix/rootvol cryptdevice=/dev/sda1:root +initrd /boot/initramfs-linux-libre-lts.img +@end verbatim + +Note: the underlined parts above (-lts) can also be removed, to boot the latest kernel instead of LTS (long-term support) kernels. You could also copy the menu entry and in one have -lts, and without in the other menuentry. You could also create a menu entry to load /boot/vmlinuz-linux-libre-grsec and /boot/initramfs-linux-libre-grsec.img The first entry will load by default. + +Without specifying a device, the @emph{-a} parameter tries to unlock all detected LUKS volumes. You can also specify -u UUID or -a (device). + +Now, to protect your system from an attacker simply booting a live usb distro and re-flashing the boot firmware, we are going to add a password for GRUB. In a new terminal window, if you are not yet online, start dhcp on ethernet:@* # @strong{systemctl start dhcpcd.service} Or make sure to get connected to the internet in any other way you prefer, at least. + +Use of the @emph{diceware method} is recommended, for generating secure passphrases (instead of passwords). + +AGAIN: MAKE SURE TO DO THIS WHOLE SECTION ON grubtest.cfg *BEFORE* DOING IT ON grub.cfg. (When we get there, upon reboot, select the menu entry that says @emph{Switch to grubtest.cfg} and test that it works. Only once you are satisfied, copy that to grub.cfg. Only a few steps to go, though.) WHY? BECAUSE AN INCORRECTLY SET PASSWORD CONFIG MEANS YOU CAN'T AUTHENTICATE, WHICH MEANS 'BRICK'. + +(emphasis added, because it's needed: this is a common roadblock for users.) + +We need a utility that comes with GRUB, so we will download it temporarily. (Remember that GRUB isn't needed for booting, since it's already included as a payload in libreboot.) Also, we will use flashrom, and I installed dmidecode. You only need base-devel (compilers and so on) to build and use cbfstool. It was already installed if you followed this tutorial, but here it is:@* # @strong{pacman -S grub flashrom dmidecode base-devel}@* Next, do:@* # @strong{grub-mkpasswd-pbkdf2}@* Enter your chosen password at the prompt and your hash will be shown. Copy this string - you will add it to your grubtest.cfg. + +The password below (it's @strong{password}, by the way) after @emph{'password_pbkdf2 root'} @emph{should be changed} to your own. Make sure to specify a password that is different from both your LUKS *and* your root/user password. Obviously, do not simply copy and paste the examples shown here... + +Next, back in grubtest.cfg, above the first 'Load Operating System' menu entry, you should now add your GRUB password, like so (replace with your own name (I used @strong{root} on both lines, feel free to choose another one) and the password hash which you copied): + +@verbatim +set superusers="root" +password_pbkdf2 root grub.pbkdf2.sha512.10000.711F186347156BC105CD83A2ED7AF1EB971AA2B1EB2640172F34B0DEFFC97E654AF48E5F0C3B7622502B76458DA494270CC0EA6504411D676E6752FD1651E749.8DD11178EB8D1F633308FD8FCC64D0B243F949B9B99CCEADE2ECA11657A757D22025986B0FA116F1D5191E0A22677674C994EDBFADE62240E9D161688266A711 +@end verbatim + +Save your changes in grubtest.cfg, then delete the unmodified config from the ROM image:@* $ @strong{./cbfstool libreboot.rom remove -n grubtest.cfg}@* and insert the modified grubtest.cfg:@* $ @strong{./cbfstool libreboot.rom add -n grubtest.cfg -f grubtest.cfg -t raw}@* + +Now refer to @uref{http://libreboot.org/install/index.html#flashrom,http://libreboot.org/install/index.html#flashrom}.

VERIFIED." written at the end of the flashrom output. + +With this new configuration, Parabola can boot automatically and you will have to enter a password at boot time, in GRUB, before being able to use any of the menu entries or switch to the terminal. Let's test it out: reboot and choose grubtest.cfg from the GRUB menu, using the arrow keys on your keyboard. Enter the name you chose, the GRUB password, your LUKS passphrase and login as root/your user. All went well? Great! + +If it does not work like you want it to, if you are unsure or sceptical in any way, don't despair: you have been wise and did not brick your device! Reboot and login the default way, and then modify your grubtest.cfg until you get it right! @strong{Do *not* proceed past this point unless you are 100% sure that your new configuration is safe (or desirable) to use.} + +Now, we can easily and safely create a copy of grubtest.cfg, called grub.cfg. This will be the same except for one difference: the menuentry 'Switch to grub.cfg' is changed to 'Switch to grubtest.cfg' and, inside it, all instances of grub.cfg to grubtest.cfg. This is so that the main config still links (in the menu) to grubtest.cfg, so that you don't have to manually switch to it, in case you ever want to follow this guide again in the future (modifying the already modified config). Inside libreboot_util/cbfstool/@{armv7l i686 x86_64@}, we can do this with the following command:@* $ @strong{sed -e 's:(cbfsdisk)/grub.cfg:(cbfsdisk)/grubtest.cfg:g' -e 's:Switch to grub.cfg:Switch to grubtest.cfg:g' < grubtest.cfg > grub.cfg}@* Delete the grub.cfg that remained inside the ROM:@* $ @strong{./cbfstool libreboot.rom remove -n grub.cfg}@* Add the modified version that you just made:@* $ @strong{./cbfstool libreboot.rom add -n grub.cfg -f grub.cfg -t raw}@* + +Now you have a modified ROM. Once more, refer to @uref{http://libreboot.org/install/index.html#flashrom,http://libreboot.org/install/index.html#flashrom}. Cd to the libreboot_util directory and update the flash chip contents:@* # @strong{./flash update libreboot.rom}@* And wait for the "Verifying flash... VERIFIED." Once you have done that, shut down and then boot up with your new configuration. + +When done, delete GRUB (remember, we only needed it for the @emph{grub-mkpasswd-pbkdf2} utility; GRUB is already part of libreboot, flashed alongside it as a @emph{payload}):@* # @strong{pacman -R grub} + +If you followed all that correctly, you should now have a fully encrypted Parabola installation.

However, they run with a lot of free software at the boot software and embedded controller levels, since free software gives Google enough flexibility to optimize various aspects such as boot time and most importantly, to implement the CrOS security system, that involves various aspects of the software. Google does hire a lot of Coreboot developers, who are generally friendly to the free software movement and try to be good members of the free software community, by contributing code back. + +CrOS devices are designed (from the factory) to actually coax the user into using @uref{https://www.gnu.org/philosophy/who-does-that-server-really-serve.en.html,proprietary web services} (SaaSS) that invade the user's privacy (ChromeOS is literally just the Google Chrome browser when you boot up, itself proprietary and comes with proprietary add-ons like flash. It's only intended for SaaSS, not actual, real computing). Google is even a member of the @emph{PRISM} program, as outlined by Edward Snowden. See notes about ChromeOS below. The libreboot project recommends that the user replace the default @emph{ChromeOS} with a distribution that can be used in freedom, without invading the user's privacy. + +We also use a similar argument for the MacBook and the ThinkPads that are supported in libreboot.

User flashing from software is possible, without having to externally re-flash, but the flash chip is SPI (SOIC-8 form factor) so you can also externally re-flash if you want to. In practise, you only need to externally re-flash if you brick the laptop; read @uref{../install/bbb_setup.html,../install/bbb_setup.html} for an example of how to set up an SPI programmer. + +Write protection is useful, because it prevents the firmware from being re-flashed by any malicious software that might become executed on your GNU/Linux system, as root.

This was originally done on the ThinkPad X200, and later adapted for the ThinkPad R400/T400/T500. It can in principle be done on any GM45 or GS45 system. + +The ME is a blob that typically must be left inside the flash chip (in the ME region, as outlined by the default descriptor). On GM45, it is possible to remove it without any ill effects. All other parts of coreboot on GM45 systems (provided GMA MHD4500 / Intel graphics) can be blob-free, so removing the ME was the last obstacle to make GM45 a feasible target in libreboot (the systems can also work without the microcode blobs). + +The ME is removed and disabled in libreboot by modifying the descriptor. More info about this can be found in the ich9deblob/ich9gen source code in resources/utilities/ich9deblob/ in libreboot, or more generally on this page. + +More information about the ME can be found at @uref{http://www.coreboot.org/Intel_Management_Engine,http://www.coreboot.org/Intel_Management_Engine} and @uref{http://me.bios.io/Main_Page,http://me.bios.io/Main_Page}. + +Another project recently found: @uref{http://io.smashthestack.org/me/,http://io.smashthestack.org/me/} + +@uref{index.html,Back to previous index}. + +@node ICH9 gen utility +@chapter ICH9 gen utility +@anchor{#ich9-gen-utility} +It is no longer necessary to use @ref{#ich9deblob,ich9deblob} to generate a deblobbed descriptor+gbe image for GM45 targets. ich9gen is a small utility within ich9deblob that can generate them from scratch, without a factory.bin dump. + +ich9gen executables can be found under ./ich9deblob/ statically compiled in libreboot_util.

You probably don't want to use the generic one; the ROM images in libreboot contain a descriptor+gbe image by default (already inserted) just to prevent or mitigate the risk of bricking your laptop, but with the generic MAC address (the libreboot project does not know what your real MAC address is). + +You can find out your MAC address from @strong{ip addr} or @strong{ifconfig} in GNU/Linux. Alternatively, if you are running libreboot already (with the correct MAC address in your ROM), dump it (flashrom -r) and read the first 6 bytes from position 0x1000 (or 0x2000) in a hex editor (or, rename it to factory.rom and run it in ich9deblob: in the newly created mkgbe.c will be the individual bytes of your MAC address). If you are currently running the stock firmware and haven't installed libreboot yet, you can also run that through ich9deblob to get the mac address. + +An even simpler way to get the MAC address would be to read what's on the little sticker on the bottom/base of the laptop. + +On GM45 laptops that use flash descriptors, the MAC address or the onboard ethernet chipset is flashed (inside the ROM image). You should generate a descriptor+gbe image with your own MAC address inside (with the Gbe checksum updated to match).

Some laptops use an extra SPI flash chip for the EC, some have EC in the main chip, some don't use SPI flash at all but have the firmware inside the EC chip itself. If the EC has integrated flash then you need to be able to get to the pins on the chip or be able to program them over LPC or SPI (if they have that feature). The lenovo laptops currently supported in libreboot all use H8 EC chips (contains flash inside the chip). Read the datasheets on how to externally flash the EC. Most CrOS devices run with a free EC firmware (@uref{https://chromium.googlesource.com/chromiumos/platform/ec/+/master/chip/,https://chromium.googlesource.com/chromiumos/platform/ec/+/master/chip/}). - see @uref{http://blogs.coreboot.org/blog/2015/05/28/progress-gsoc-week-1/,http://blogs.coreboot.org/blog/2015/05/28/progress-gsoc-week-1/} (H8S EC, applies to thinkpads) + +@uref{https://github.com/lynxis/h8s-ec,https://github.com/lynxis/h8s-ec} @uref{https://events.ccc.de/congress/2010/Fahrplan/events/4174.en.html,https://events.ccc.de/congress/2010/Fahrplan/events/4174.en.html} + +@uref{https://archive.org/details/27c3-4174-en-the_hidden_nemesis,https://archive.org/details/27c3-4174-en-the_hidden_nemesis} + +T60? @uref{http://ec.gnost.info/ec-18s/ec.html,http://ec.gnost.info/ec-18s/ec.html} + +@ref{#pagetop,Back to top of page.} + +Copyright © 2014, 2015 Francis Rowe <info@@gluglug.org.uk>@* Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
