Kristoffer DalbyandKristoffer Dalby 1d82c1b3d0 gokrazy/tsapp: lock down breakglass access
Point tsapp at the tailscale/breakglass fork, fetch SSH keys from EC2
IMDSv2, restrict to the sec-scan user and internal CIDRs, start on
boot, and stop after 120s idle.

Brad FitzpatrickandBrad Fitzpatrick 0fb8226708 gokrazy, tstest, cmd/vnet: switch amd64 kernel to gokrazy/kernel.amd64
The tailscale/gokrazy-kernel module was a fork of rtr7/kernel that
stalled at Linux 6.8.9 (July 2024). All of the kernel config options we
had added in that fork (ENA, Xen for EC2, virtio-mmio for qemu microvm,
virtio RNG, IPv6 policy routing, netlink diag, etc) are now present in
the gokrazy project's own gokrazy/kernel.amd64 module, which tracks
current kernel.org releases (Linux 7.1.3 as of this change) and is the
gokrazy project's supported kernel for x86_64 PCs and VMs.

Switch the tsapp and natlabapp images, the natlab VM tests, and the
CI workflow to gokrazy/kernel.amd64, drop the tailscale/gokrazy-kernel
dependency, and update gokrazy/kernel.arm64 to latest while here.

Verified with TestEasyEasy, TestJustIPv6, and TestTailscaleSSH in
tstest/natlab/vmtest with --run-vm-tests.

Brad FitzpatrickandBrad Fitzpatrick 887005d255 cmd/tailscale: add 'configure pve-appliance' to make Proxmox VM of appliance
This is a variant of "tailscale configure flash-appliance" but for running
on Proxmox PVE hosts to make a Proxmox VM running the experimental
Tailscale Appliance.

This also makes the "Esc" key make the fbstatus GUI open up a terminal,
instead of Control-Alt-F2 which is hard to type over NoVNC.

And make gafpush unidirectional, to not require a local port be opened locally,
which I hit while working on this.

And make fbstatus included in all appliance variants, but bail out early
and stop respawing if the machine has no framebuffer (e.g. AWS VMs).

Brad FitzpatrickandBrad Fitzpatrick 76eece2d15 gokrazy, Makefile: improve appliance build tooling
Several improvements to the gokrazy appliance build and flash workflow:

gokrazy/build.go:
  - Round Pi image size up to a power of 2 (QEMU raspi3b requires it)
  - Use monogok's mkfs.Perm for the /perm ext4 partition (pure Go,
    cross-platform, no e2fsprogs dependency)

gokrazy/mkfs:
  - Accept optional PermFile entries to include in the freshly-created
    ext4 filesystem (used for breakglass authorized_keys)
  - Use progresstracking.Ticker for flush progress reporting

gokrazy/tsapp*/config.json:
  - Point breakglass at /perm/breakglass.authorized_keys (not ec2)
  - Fix Pi SerialConsole to serial0,115200 (not ttyS0)

cmd/tailscale/cli/configure-flash-appliance.go:
  - Add --add-ssh-authorized-keys flag to write an authorized_keys
    file into /perm during flash (for breakglass SSH access)
  - Use progresstracking.CountingWriter + Ticker for write progress

Makefile:
  - tsapp-build-and-flash-pi: auto-include ~/.ssh/id_ed25519.pub
  - tsapp-qemu-pi: use virt machine + UEFI + ramfb + e1000 (working
    network + framebuffer), with DTB watchdog patch and
    gokrazy.log_to_serial for debugging
  - Auto-detect UEFI firmware path across Debian/Homebrew/Fedora

Brad FitzpatrickandBrad Fitzpatrick fad8b9b8a9 clientupdate, cmd/tailscale: verify signed GAFs, wire up tailscale update for Gokrazy
Builds on top of the unsigned URL-based GAF update flow added previously
(see referenced issue for context). The pkgs.tailscale.com server now
publishes signed GAFs for the unstable track, with detached ed25519
signatures produced by pkgsign's signdist path (the same distsign scheme
used for every other release artifact). This change consumes them.

The URL-based path (tailscale update --gokrazy-update-from-url=URL) now
verifies the signature by default using clientupdate/distsign.Client,
which fetches distsign.pub from the root of the host serving the GAF and
checks the .sig against the root keys embedded in this binary. The
--unsigned flag stays for TestGokrazyUpdatesItselfToSameImage, whose
in-test fileserver does not publish distsign.pub.

The bare tailscale update path is now wired up for the Tailscale
appliance image. It fetches <pkgs>/<track>/?mode=json, picks the GAF
whose key matches the local device (vm-amd64, vm-arm64, or pi-arm64,
where arm64 is split via /sys/firmware/devicetree/base/model), confirms
the version with the user, and reuses the verified download path above.

To avoid wiping a user's custom Gokrazy build that happens to include
tailscaled, the bare update path is gated on hostinfo.Package == "tsapp",
which is only set when the new ts_appliance build tag is present
(mirroring the existing ts_package_container tag). The
gokrazy/tsapp*/config.json files now pass GoBuildTags ["ts_appliance"]
for the tailscale and tailscaled packages so monogok bakes the tag into
the official appliance builds. The TS_FORCE_ALLOW_TSAPP_UPDATE env var
is an escape hatch for callers who want to force the appliance update
path on a non-appliance build. The URL-based path stays ungated since it
requires explicit user intent (and is exercised by the natlab vmtest).

Brad FitzpatrickandBrad Fitzpatrick 70f0b261b6 go.mod, gokrazy: bump to fork of gokrazy/gokrazy init process for syslog change
When we switched to monogok in 371d6369cd, we lost our gokrazy fork's
change to let the syslog be configured from the Linux cmdline.

That's sent upstream in gokrazy/gokrazy#275 but still in review. Meanwhile,
revert to a fork, while still keeping monogok. Monogok was updated to
support an alternate init package, which is now hosted temporarily at
https://github.com/tailscale/ts-gokrazy

This means we can rip out the log polling loop out of pending PR #19568
and go ack to using syslog.

Andrew Dunham f572286bf9 gokrazy, various: use point versions of Go and update Nix deps
This un-breaks vim-go (which doesn't understand "go 1.23") and allows
the natlab tests to work in a Nix shell (by adding the "qemu-img" and
"mkfs.ext4" binaries to the shell). These binaries are available even on
macOS, as I'm testing on my M1 Max.

These three packages aren't in gokrazy/tsapp/config.json but

in the resulting image. Apparently `gok` doesn't delete them or
warn about them being present on disk when they're moved from
the config file.

Brad FitzpatrickandBrad Fitzpatrick 10d0ce8dde tstest/natlab: get tailscaled logs from gokrazy via syslog
Using https://github.com/gokrazy/gokrazy/pull/275

This is much lower latency than logcatcher, which is higher latency
and chunkier. And this is better than getting it via 'tailscale debug
daemon-logs', which misses early interesting logs.
