Daniel Barlow 74f2aa6247 initramfs-peek: an initramfs image with a shell, for debugging 2023-05-06 23:03:51 +01:00
Daniel Barlow 888a0d5f74 mips-vm: allow env var to override la network interface 
this is handy if you want to connect to it from the host
for e.g. seeing if min-copy-closure works
 2023-05-06 23:01:56 +01:00
Daniel Barlow 30153a2d4e add min-copy-closure, a minimal nix-copy-closure substitute 2023-05-06 22:47:03 +01:00
Daniel Barlow 67768004ee erase full flash, it seems to help with jffs2 2023-04-26 22:19:01 +01:00
Daniel Barlow 26c6eac937 delete config boot.tftp.enable as it doesn't enable anything 2023-04-26 22:18:23 +01:00
Daniel Barlow 4cfaed7303 specify root device as /dev/mtdblockn 
the (openwrt?) magic that autodetects it based on mtd labels
won't work with a two-stage boot
 2023-04-26 22:16:15 +01:00
Daniel Barlow 6d6dbe1cbb tftpboot: allow padding image with freeSpaceBytes 
this is useful for writable filesystems so that there's more than
an erase block of space to write into
 2023-04-26 22:15:19 +01:00
Daniel Barlow 151dc88c28 little evidence of thinking 2023-04-23 21:24:37 +01:00
Daniel Barlow 2f3b108ef1 tftpboot: set phram erase block size to match hardware 
this is needed for tftp boot with a jffs2 filesystem
 2023-04-23 21:24:37 +01:00
Daniel Barlow 6adab44fcf rotuer; run chronyd for accurate time 2023-04-23 20:56:20 +01:00
Daniel Barlow 4342d3403f make rotuer example build again 2023-04-23 20:56:20 +01:00
Daniel Barlow 28264febdb add smaller-than-gnu "hello world" package 2023-04-23 20:56:20 +01:00
Daniel Barlow 2c4f8b823e remove jffs2boot target 
It's not needed now initramfs is compiled into the kernel.
 2023-04-23 20:56:20 +01:00
Daniel Barlow 3595e36294 workaround for huge musl binaries 
something in our configuration is causing gcc to generate binaries
in excess of 68K for "hello world". hardeningDisable seems to stop it
doing that, turning it on for s6 which writes _lots_ of binaries
but would be good to get to the bottom of this

Daniel Barlow c7aa8c7756 some notes on how we couldn't make it smaller 2023-04-19 22:03:18 +01:00

Daniel Barlow 65dfbad365 systemconfig: chown files if uid/gid > 0 2023-04-15 22:53:28 +01:00
Daniel Barlow 5dd0c6e3c0 rewrite preinit as very small C program 
By using the kernel "nolibc" header to avoid requiring a C library, we
can bring the initramfs size to around 4k

This does involve a tiny bit of inline mips assembly which I'm not
sure about. gcc seems unwilling to generate the code to load $gp at
function entry of main(), so we do it by hand - but I'd rather find
out why gcc doesn't.

Daniel Barlow b1a89ae8c3 jffs2: squash uids, enable lzo compression 2023-04-15 17:23:58 +01:00
Daniel Barlow 11f2715d18 mips-vm: enlarge mtd 2023-04-15 17:22:35 +01:00
Daniel Barlow 1cc0b13b57 rewrite systemconfig in C and link statically 
systemconfig (a.k.a "activate") is run from the initramfs. Converting
it from a shell script to an executable means it doesn't depend on
there being a shell in the initramfs
 2023-04-15 17:21:27 +01:00
Daniel Barlow c744ef8c17 systemconfig: accept uid and gid options 
all we do with them is assert they're zero, to unbreak CI.
This code is getting rewritten anyway
 2023-04-14 23:19:56 +01:00
Daniel Barlow 9f3c80e774 make initramfs busybox (very slightly) smaller 2023-04-11 23:08:02 +01:00

Daniel Barlow 0a2881914b set erase block size to something that works for jffs2 2023-04-10 22:57:50 +01:00
Daniel Barlow 4638092d3d build initramfs into kernel 
this doesn't matter for qemu, but there's no other way of
getting a hardware device to find it if the bootloader
won't co-operate
 2023-04-10 22:57:50 +01:00
Daniel Barlow 633a4f8003 move BLK_DEV_INITRD to base.nix 2023-04-10 22:57:50 +01:00
Daniel Barlow fe99abc450 shrink rsync 
remove openssl requirement, it  uses it for "optimised assembly
versions" of md5 - but only on x86/arm/sparc not mips anyway
 2023-04-10 22:57:50 +01:00
Daniel Barlow 42725f56f9 make jffs2 module provide o.rootfs, conditionally 
it's enabled if config.rootfsType == "jffs2"
 2023-04-10 20:01:58 +01:00
Daniel Barlow 63a89f7d0d add config.boot.initramfs.enable 2023-04-10 19:07:27 +01:00
Daniel Barlow 07eb3d66da remove unused combined-image output 2023-04-10 18:15:48 +01:00
Daniel Barlow 0687ae7f5c rename flashable->flashimage, o.squashfs to rootfs 
"rootfs" describes what it is for, "squashfs" merely says
how it's implemented

(also, rootfs-as-jffs2 will soon be added)

Daniel Barlow f5156425a2 correct jffs2 endian, remove unused bindings 2023-04-07 09:39:47 +01:00
Daniel Barlow db54c877d6 add CI test for jffs2 2023-04-06 20:58:26 +01:00
Daniel Barlow 54a1ab3529 support jffs2, with initramfs 
the jffs2 filesystem contains only /nix/store and a script which is
run in early init (initramfs) and is responsible for recreating
"traditional" directories (/bin /etc/**/* /var &c) based on the
configuration.

this is tested only in qemu so far and could use some cleanup
 2023-04-04 23:35:49 +01:00
Daniel Barlow 25d9da967c remove support for sockets in pseudofiles 
(1) we can't make them on a real filesystem except by running
something that calls socket()
(2) whyever would we want to?
 2023-04-04 23:23:22 +01:00

Daniel Barlow 342c87b256 qemu: boot from mtd using mtd2block 
doesn't make much difference for squashfs but this will make it much
simpler to test jffs2/ubifs

Daniel Barlow 3194262eb3 it has not been a production-ready week 2023-03-31 23:44:49 +01:00
Daniel Barlow 98243d43da add mtdutils mkfs.jffs2 --graft option 
we'd like a bit more of the convenience of mksquashfs
(never thought I'd say _that_) for jffs2, in particular
not having to copy all the desired store paths into a
single directory just so we can create an image from them

Daniel Barlow a172180be8 don't set lua5_3 in overlay 
sphinx depends on lua5_3, so overriding it globally means rebuilding
that - which isn't really necessary

Daniel Barlow f5a7b78679 rename kexec-tools-static 
it doesn't build natively on x86-64 and I don't suppose we need it to
anyway

Daniel Barlow a5cfa37ed3 unify kernel command line handling 
We now use MIPS_CMDLINE_DTB_EXTEND for all boot varieties
(tftpboot, flash boot, kexec) with the addition of
MIPS_BOOTLOADER_CMDLINE_REQUIRE_COOKIE - local patch -
so that the bootloader args are ignored unless they
contain the string "liminix"

Daniel Barlow 4b19568f1b add kexecboot 
This allows booting a new image from a running OS, creating a
phram mtd for the root squashfs

* enable CONFIG_KEXEC
* add modules/kexecboot
* patch kexec-tools to add --map-file option for the squashfs
* patch kernel kexec code to call new kernel with DTB

Daniel Barlow 3c6ec354ce move root's home directory to /home/root 
/ is a bad choice of home directory

/home/root instead of /root is to make it easier to write
