 * newer U-Boot version
 * util-linux can now be built (previously depended on systemd)

+2024-01-30

+New port! Thanks to Arnout Engelen <arnout@bzzt.net>, Liminix
+now runs on the TP-Link Archer AX23
+
+2024-02-12
+
+* We now build wifi drivers (mac80211) from the same kernel source as
+the running kernel, instead of using drivers from the linux-backports
+project.  This may be a regression on some devices that depend on
+OpenWrt patches for wireless functionality: if you have a device that
+used to work and now doesn't, refer to OpenWrt
+package/kernel/mac80211/patches/ to see if there's something in there
+that needs to be applied.
+
+* in general, we build kernel modules (e.g. for nftables) at the same
+time as the kernel itself instead of expecting to be able to build
+them afterwards as though they were "out of tree". Refer to commit
+b9c0d93670275e69df24902b05bf4aa4f0fcbe96 for a fuller explanation
+of how this simplifies things.
+
+2024-02-13
+
+So that we can be more consistent about services that would like their
+state to be preserved across boots (assuming a writable filesystem)
+these changes have been made
+
+* /run/service-state has been moved to /run/services/outputs
+ to better reflect what it's used for
+* /run/services/state is either a symlink to /persist/services/state
+ (if there's a writeable fs on /persist) or a directory (if there
+ isn't)
+
+The change will lose your ssh host key(s) unless you copy them from
+the old location to the new one before rebooting into the new system
+
+   mkdir -m 02751 -p /run/services/state/dropbear
+   cp /persist/secrets/dropbear/* /run/services/state/dropbear
+
+The `output`, `mkoutputs` functions defined by ${serviceFns}
+have been updated for the new location.
+
+2024-02-16
+
+New (or at least, previously unreported) port! Liminix now runs on the
+Turris Omnia and has been serving my family's internet needs for most
+of this week.  Thanks to NGI0 Entrust and the NLnet Foundation for
+sponsoring this development (and funding the hardware)

+Before calling the Omnia "done" I'd like to get it to the point that
+I can actually use it as a CPE. This means
+
+- writing something down about how we handle static addresses
+  - hosts that need static ipv6 can configure it themselves as ::n
+    where n is a small number. this won't clash with slaac
+  - the `hosts` param to dnsmasq can specify static ipv4
+
+- dealing with port forwards and allowed incoming in the firewall
+
+- would be quite cool to run sniproxy instead of forwarding to
+  loaclhost (extra credit)

+
+ARGH KERNEL
+
+You can't define CONFIG_NETFILTER=y in a monolithic kernel and expect
+later to separately build some modules that use it, because there are
+a bunch of symbols that only get defined if certain other CONFIG
+options are set at the time that the monolithic kernel is built.
+
+https://github.com/torvalds/linux/blob/master/net/netfilter/core.c#L689
+
+Another example is
+https://github.com/torvalds/linux/blob/master/include/linux/netdevice.h#L160
+- if you decide after building the kernel that you're going to build
+some wireless modules, you can't do that without rebuilding the kernel
+so that it knows to expect them
+
+The moral of the story seems to be: if you have a compiled Linux kernel source tree and you change some symbol from "is not set" to m and then run  make modules, you cannot in general expect that newly compiled  module to work.
+
+AP advertised VHT without HT, disabling HT/VHT/HE
+
+TODO
+
+- [done] support kernel version as parameter to builder pkgs/kernel/default.nix
+- [done] extract the change in how module loading works from omnia device config,
+  and fix the other thing that uses it
+- [axed] wlan module to take 'backported' as a parameter
+  half of the omnia conditionalConfig can go into the module
+- [done] upgrade omnia to kernel v6
+- figure out what mdns we need for local hostname resolution
+  (maybe bridging lan/wlan)?
+- [DONE] slow wifi because "AP advertised VHT without HT, disabling HT/VHT/HE"
+- [DONE] add local domain to secrets
+- run sniproxy instead of forwarding
+- [test] forward some port to loaclhost 22 for inbound ipv4 ssh

+
+Before we put this back live, would be good to
+
+[done] 1) move the leases file into /persist
+
+I think we'll do /persist/service/<name>/ and change ssh to use the same
+scheme.
+
+we could put mkpersist() in serviceFns which would check for /persist
+and return a directory in /persist/service/ or /run/service-state
+
+(will something bad happen if we use /run/service-state? it will also
+expose the thingy as an output, but whether it's accessible that way
+will depend on whether there's a writable fs or not, which is unexpected)
+
+: rename service-state to  /run/services/outputs
+: on boot
+:  if /persist
+:    create /persist/services/state and symlink /run/services/state to it
+:  else create /run/services/state
+
+
+[done] 2) maybe change the local domain back to .lan?  setting up
+  systemd-networkd with search domains is an awful faff
+
+[done] 3) work out what to do with incoming ssh from wan
+
+- For noetbook and thinkpad we have a vpn anyway so can expect to
+  reach loaclhost directly using ipv6
+
+- stop ssh from ever trying to get to our ipv4 address.
+  - we could get rid of A record for loaclhost.telent.net but
+    there are a bunch of CNAMES pointing at it for web servers.
+  - we could reject incoming connections to tcp4 port 22 in firewall
+    and then there is a clear signal to Dont Do That Then
+
+- for emergency use, dnat ipv4 2200 and 2201 to rotuer and loaclhost
+
+Tue Feb 13 22:31:03 GMT 2024
+
+* the reason we can't reboot is that there is a service to add each
+lan device to the bridge which does ifwait $dev running, which doesn't
+return until there's something plugged in. So s6-rc hangs indefinitely
+until the lan switch is fully populated. This is definitely a "next
+milestone" thing.
+
+* another example of "thing that depends on other thing but which it
+  is actually OK if neither of them happen" might be "mount a
+  filesystem if there is a usb mass storage device attached"
+
+* I don't know if failover also fits into the model we don't quite
+  have. LTE route depends on pppoe not being healthy
+
+we can have services (or bundles) that aren't part of the default target,
+and plumb them into events of some kind (netlink?) to bring them up/down?
+
+we can use s6-rc instanced services:
+https://skarnet.org/software/s6/instances.html
+
+"s6-instance-create and s6-instance-delete are relatively expensive operations, because they have to recursively copy or delete directories and use the synchronization mechanism with the instance supervisor, compared to s6-instance-control which only has to send commands to already existing supervisors. If you are going to turn instances on and off on a regular basis, it is more efficient to keep the instance existing and control it with s6-instance-control than it is to repeatedly create and delete it. "
+
+Probably we need something that reads netlink messages and converts
+them to a format that we can use to control services. Is there a
+benefit to using services here and not just running commands? it means
+the system state change we desire will stay changed.
+
+TODO items not to lose track of
+
+- speed testing (iperf)
+- make gl-ar750 tftpboot build again
+- finish belkin
+- install sniproxy
+- is there something simple we can do to make it reboot again?
+- turn rotuer,extneder examples into "profiles" that don't embed
+  hardware specifics
+
+Thu Feb 15 11:50:56 GMT 2024
+
+1) to make tftpboot work with old bootm implementations we need
+
+- compressed root
+- uncompressed root
+- kernel with dtb
+ dtb needs to know where uncompressed rootfs is and how big
+
+2) if the image is a zImage (arm32) or an Image (arm64) we have to stick
+with the three-arg bootz, and the dtb has to be lower in ram than the kernel
+
+Fri Feb 16 15:43:32 GMT 2024
+
+DHCP6c refresh is still wrong. We get updates for an address that
+hasn't changed prefix or length, when the expiry times have changed,
+and we can't action that by remove;add because remove will wipe out
+any routes through the interface but add won't put them back
+
+We can use "change" for both adds and changes, but we need to know that
+a change is not a delete
+
+The "identity" of an address is the address itself: kernel won't
+let you add the same address with two different prefixes.
+
+Keeping it simple, we could call "change" on every address in the
+new-addresses list and "del" on every address in old-addresses
+that is no longer in new-addresses
+
+If the upstream has changed length, "ip addr change" is ignored,
+so it needs to be in deleted as well as added/changed

+    Hardware summary
+    ================
+
+    - MediaTek MT7621 (880MHz)
+    - 16MB Flash
+    - 128MB RAM
+    - WLan hardware: Mediatek MT7905, MT7975
+
+    Limitations
+    ===========
+
+    Status LEDs do not work yet.
+
+    Uploading an image via tftp doesn't work yet, because the Archer uboot
+    version is so old it doesn't support overriding the DTB from the mboot
+    command. The tftpboot module doesn't support this yet, see
+    https://gti.telent.net/dan/liminix/pulls/5 for the WiP.

    to work (and provides you an easy rollback if you decide you don't
    like Liminix after all).

-    The install process is designed so that you should not need to open
-    the device and add a serial console (although it may be handy
-    for visibility  and in case anything goes wrong). In outline
+    The install process has two stages, and is intended that you
+    should not need to open the device and add a serial console
+    (although it may be handy for visibility, and in case anything
+    goes wrong). First we build a minimal installation/recovery
+    system, then we reboot into that recovery image to prepare the
+    device for the full target install.

-      1. build a "recovery" system with useful btrfs tools
-      2. boot that system using TFTP or a USB stick
-      3. once booted, mount the real root filesystem on /mnt
-      4. take a snapshot using schnapps, and then delete everything
-      5. use min-copy-closure -d /mnt/@ to copy the real configuration
-         to the device
-      6. reboot into a fully operational system
+    Installation using a USB stick
+    ==============================
+
+    First, build the image for the USB stick. Review
+    :file:`examples/recovery.nix` in order to change the default
+    root password (which is ``secret``) and/or the SSH keys, then
+    build it with
+
+    .. code-block:: console
+
+        $ nix-build -I liminix-config=./examples/recovery.nix \
+          --arg device "import ./devices/turris-omnia" \
+          -A outputs.mbrimage -o mbrimage
+        $ file -L mbrimage
+        mbrimage: DOS/MBR boot sector; partition 1 : ID=0x83, active, start-CHS (0x0,0,5), end-CHS (0x6,130,26), startsector 4, 104602 sectors
+
+    Next, copy the image from your build machine to a USB storage
+    medium using :command:`dd` or your other most favoured file copying
+    tool, which might be a comand something like this:
+
+    .. code-block:: console
+
+        $ dd if=mbrimage of=/dev/path/to/the/usb/stick \
+          bs=1M conv=fdatasync status=progress
+
+    The Omnia's default boot order only checks USB after it has failed
+    to boot from eMMC, which is not ideal for our purpose.  Unless you
+    have a serial cable, the easiest way to change this is by booting
+    to TurrisOS and logging in with ssh:
+
+    .. code-block:: console
+
+        root@turris:/# fw_printenv boot_targets
+        boot_targets=mmc0 nvme0 scsi0 usb0 pxe dhcp
+        root@turris:/# fw_setenv boot_targets usb0 mmc0
+        root@turris:/# fw_printenv boot_targets
+        boot_targets=usb0 mmc0
+        root@turris:/# reboot -f
+
+    It should now boot into the recovery image. It expects a network
+    cable to be plugged into LAN2 with something on the other end of
+    it that serves DHCP requests.  Check your DHCP server logs for a
+    request from a ``liminix-recovery`` host and figure out what IP
+    address was assigned.
+
+    .. code-block:: console
+
+        $ ssh liminix-recovery.lan
+
+    You should get a "Busybox" banner and a root prompt. Now you can
+    start preparing the device to install Liminix on it. First we'll
+    mount the root filesystem and take a snapshot:
+
+    .. code-block:: console
+
+        # mkdir /dest && mount /dev/mmcblk0p1 /dest
+        # schnapps -d /dest create "pre liminix"
+        # schnapps -d /dest list
+        ERROR: not a valid btrfs filesystem: /
+            # | Type      | Size        | Date                      | Description
+        ------+-----------+-------------+---------------------------+------------------------------------
+            1 | single    |    16.00KiB | 1970-01-01 00:11:49 +0000 | pre liminix
+
+    (``not a valid btrfs filesystem: /`` is not a real error)
+
+    then we can remove all the files
+
+    .. code-block:: console
+
+        # rm -r /dest/@/*
+
+    and then it's ready to install the real Liminix system onto. On
+    your build system, create the Liminix configuration you wish to
+    install: here we'll use the ``rotuer`` example.
+
+    .. code-block:: console
+
+        build$ nix-build -I liminix-config=./examples/rotuer.nix \
+          --arg device "import ./devices/turris-omnia" \
+          -A outputs.systemConfiguration
+
+    and then use :command:`min-copy-closure` to copy it to the device.
+
+    .. code-block:: console
+
+        build$ nix-shell --run \
+          "min-copy-closure -r /dest/@  root@liminix-recovery.lan result"
+
+    and activate it
+
+    .. code-block:: console
+
+        build$ ssh root@liminix-recovery.lan \
+          "/dest/@/$(readlink result)/bin/install /dest/@"
+
+    The final steps are performed directly on the device again: add
+    a symlink so U-Boot can find :file:`/boot`, then restore the
+    default boot order and reboot into the new configuration.
+
+    .. code-block:: console
+
+        # cd /dest && ln -s @/boot .
+        # fw_setenv boot_targets "mmc0 nvme0 scsi0 usb0 pxe dhcp"
+        # cd / ; umount /dest
+        # reboot
+
+
+    Installation using a TFTP server and serial console
+    ===================================================
+
+    If you have a :ref:`serial` console connection and a TFTP server,
+    and would rather use them than fiddling with USB sticks, the
+    :file:`examples/recovery.nix` configuration also works
+    using the ``tftpboot`` output. So you can do
+
+    .. code-block:: console
+
+        build$ nix-build -I liminix-config=./examples/recovery.nix \
+          --arg device "import ./devices/turris-omnia" \
+          -A outputs.tftpboot
+
+    and then paste the generated :file:`result/boot.scr` into
+    U-Boot, and you will end up with the same system as you would
+    have had after booting from USB. If you don't have a serial
+    console connection you could probably even get clever with
+    elaborate use of :command:`fw_setenv`, but that is left as
+    an exercise for the reader.

+  For development, the `GL.iNet GL-MT300A <https://www.gl-inet.com/products/gl-mt300a/>`_
+  is an attractive choice as it has a builtin "debrick" procedure in the
+  boot monitor and is also comparatively simple to
+  attach serial cables to (soldering not required), so it
+  is lower-risk than some devices.
+
+  For a more powerful device, something with an ath10k would be the safe bet,
+  or the Linksys E8450 which seems popular in the openwrt community.

+        *****************
+
+        For creating 'safeloader' images for tp-link devices.
+
+        These can be flashed to the device using the firmware update feature
+        in the TP-link web UI or the OEM bootloader recovery: Use something
+        sharp to hold the 'reset' button while turning on the router until
+        only the orange LED remains lit. The router will assume IP address
+        192.168.0.1 and expect you to take 192.168.0.5 on one of the LAN ports.
+        On NixOS, use something like::
+
+            networking.interfaces.enp0s20f0u1c2 = {
+              ipv4.addresses = [ {
+                address = "192.168.0.5";
+                prefixLength = 24;
+              } ];
+            };
+            networking.networkmanager = {
+                unmanaged = [ "enp0s20f0u1c2" ];
+            };
+
+        This connection is rather somewhat temperamental, it may take a couple
+        of attempts, possibly re-attaching the USB dongle and running
+        ``systemctl restart network-start.service``. The web interface does not
+        give accurate feedback (the progress bar is a lie), so you may want
+        to upload the firmware using ``curl -F firmware=@result http://192.168.0.1/f2.htm``.
+        After this shows a 'success' JSON, the image still needs to be
+        transferred from memory to flash, so be patient.
+      '';

Daniel Barlow	c373152673	make tftpboot work on devices with old u-boot Some devices have a U-boot variant that does not accept a third parameter on the "bootm" command, meaning we can't override the dtb in the bootloader so have to smush it back into the kernel image This doesn't work in QEMU but I think the problem is with the U-Boot configuration for QEMU. It does work on at least one hardware device so I'm pushing it anyway Based on https://gti.telent.net/raboof/liminix/src/branch/tftp-old-uboot Co-authored-by: Arnout Engelen <arnout@bzzt.net>	2024-02-15 23:44:47 +00:00

Daniel Barlow	b9c0d93670	build modules at same time as main kernel vmlinux This changes the practice for building kernel modules: now we expect that the appropriate Kconfig symbols are set to =m in config.kernel.config, and then use pkgs.kmodloader to create a service that loads and unloads all the modules depended on by a particular requirement. Note that modules won't be installed on the target device just by virue of having been built: only the modules that are referenced by a kmodloader package will be in the closure. An example may make this clearer: see modules/firewall/default.nix in this commit. Why? If you have a compiled Linux kernel source tree and you change some symbol from "is not set" to m and then run make modules, you cannot in general expect that newly compiled module to work. This is because there are places in the build of the main kernel where it looks to see which modules _may_ be defined and uses that information to accommodate them. For example in an in-kernel build of https://github.com/torvalds/linux/blob/master/net/netfilter/core.c#L689 some symbols are defined only if CONFIG_NF_CONNTRACK is set, meaning this code won't work if we have it unset initially then try later to enable it and build modules only. Or see https://github.com/torvalds/linux/blob/master/include/linux/netdevice.h#L160	2024-02-11 23:47:11 +00:00
