Split the priv-socket wire types (PrivRequest/PrivResponse/PrivEvent and
friends) out of hive-sh4re into their own hive-priv-sock crate, mirroring
the existing hive-host-sock split. hive-priv — the root-privileged
helper — now depends on just this narrow protocol crate instead of the
much larger daemon-shared crate, shrinking its dependency surface and
making the privsep boundary easier to audit. No server/client
implementation lives here, only the wire contract; hive-c0re still
depends on hive-sh4re directly for everything else.
argus flagged (approving) that an unvalidated label could build a path
outside the state dir; mara called it out as a usability issue in its
own right, not just a low-risk security nit — a typo'd label should
give a precise 'not a valid label' error, not a confusing file-not-found
or an unexpected traversal.
Reject anything outside the plain lowercase+digits+hyphens charset
dashboard/extra_forges.rs already enforces on write, before touching
the filesystem at all.
Targets a dashboard-provisioned external forge account (FORGES tab)
instead of the internal forge: resolves `forge-<label>-token` for the
token and `forge-<label>.json`'s base_url for the URL, the same two
files dashboard/extra_forges.rs writes, instead of
HIVE_FORGE_URL/forge-token. Falls back to today's behavior when unset.
Orthogonal to -r/--repo.
An unknown label gives a clear error listing the labels actually found
in the state dir instead of a raw file-not-found. The base_url JSON key
is read via a typed sidecar struct pinned to what extra_forges.rs
writes, so the read side can't silently drift from the write side.
- regenerate docs/tools/hivectl-cli.md for the new `subvol snapshot send` verb
- close the TOCTOU on the no-overwrite guard: File::options().create_new(true)
(O_CREAT|O_EXCL) instead of exists()-then-create, so the guarantee is
atomic against a concurrent request racing the same dest filename
- warn (not silently swallow) if cleaning up a partial export after a
failed btrfs send itself fails, so a stuck garbage file masquerading
as a completed export is visible in the log
SendAgentSnapshotToFile priv op: btrfs send [-p <parent>] <snapshot> to a
file under MIGRATE_STAGING_ROOT. Standalone-useful as a point-in-time
snapshot export/backup today; the cross-hive ssh-piped leg (auth/trust
design posted on #1763, awaiting mara/damocles steer) is a later,
separate piece this doesn't block on.
- hive-sh4re: PrivRequest::SendAgentSnapshotToFile + MIGRATE_STAGING_ROOT
- hive-priv: validates names, refuses to overwrite an existing export,
cleans up a partial file on btrfs send failure
- hive-c0re: priv_client::send_agent_snapshot_to_file
- hivectl: `hivectl subvol snapshot send <agent> <label> [--parent <label>] --dest <file>`
nix/modules/ was restructured into nix/host-modules/ + nix/agent-modules/
before the extra-forges branch merged; this doc-only fix from PR #2422
(e53f70ac) landed after the merge went through and got dropped. Reapplying
directly against main.
Per mara: "i would have even disallowed ., we are making up the rules
here lets go strict". validate_credential_name now restricts to
[A-Za-z0-9_-] (no dot at all) instead of [A-Za-z0-9_.-] + a separate
".." substring check — simpler rule, and there's no legitimate need
for a dot in either a systemd credential id or a hive- prefixed
snapshot label. Matching hivectl client-side check + wire-proto doc
comments updated.
Per mara's review: validate_credential_name allowed any [A-Za-z0-9_.-]
byte sequence, which permits a literal ".." substring. Not currently
exploitable (snapshot_path() embeds the label inside a single
format!()'d path component with no "/" in the allowed charset, so
there's no directory to traverse into), but it's a landmine for any
future caller that builds a path via PathBuf::from(name) directly
instead of the current string-embedding. Reject ".." outright in the
shared validator, plus a matching client-side check in hivectl for
fail-fast UX (hive-priv's copy is still the authoritative one).
Per mara's PR review:
- snapshot label is now mandatory (was optional w/ timestamp default)
and must start with "hive-" — hive-priv enforces this as an
allow-list on top of the existing credential-name charset check, so
only hivectl-issued labels can reach the btrfs shellout.
- nest under `subvol snapshot create`/`subvol snapshot delete`
instead of othering delete as a separate top-level `delete-snapshot`
verb.
Per argus's review:
- regenerate docs/tools/hivectl-cli.md (hivectl markdown-docs) to
include the new subcommands — CI's hivectl-docs-fresh check compares
this file against generated output.
Adds the first missing piece from #2391's migration-gaps list: a
read-only btrfs snapshot priv op so hivectl migrate can freeze a
consistent point-in-time copy of an agent's state subvolume for
btrfs send, without stopping the live agent.
- PrivRequest::SnapshotAgentSubvolume / DeleteAgentSnapshot (hive-sh4re)
- hive-priv handlers: btrfs subvolume snapshot -r / delete, sibling
dot-prefixed path (<AGENT_STATE_ROOT>/.<agent>.snapshot.<label>)
- hive-c0re::priv_client wrappers
- hivectl subvol snapshot / delete-snapshot verbs (no agent stop needed
— btrfs snapshots are atomic against a live subvolume)
Does not yet wire actual btrfs send/receive or the hivectl migrate
verb — those stay tracked on #2391 as separate follow-up pieces.
extra.rs (external-forge account minting) was removed in the
dashboard-provisioned redesign; TOKEN_SCOPES only applies to tokens
hive-c0re mints itself on the internal forge. External forge tokens
are pasted by the operator verbatim, so we never mint them and don't
need to know their scope.
Per mara's feedback on PR #2407 ("better: you can also provide url in
dashboard, same as with matrix, no host config"), drops
services.hyperhive.extraForges and the admin-API mint/revoke flow
entirely. The operator now creates a token on the external forge
themselves and pastes a label + base URL + access token into the
dashboard's FORGES tab, the same shape as the GitHub PAT flow plus the
base-URL field from the matrix extra-account flow. hive-c0re only ever
writes/deletes two local files per account (forge-<label>-token,
forge-<label>.json sidecar for the URL) via hive-priv — no remote
account creation, no admin token, no revoke-on-the-remote-side, no nix
config to enumerate.
- nix/host-modules/hive-forge/default.nix: removed the extraForges
option, its label-format assertion, and the HYPERHIVE_EXTRA_FORGES
env forwarding.
- hive-c0re/src/forge/extra.rs: deleted (REST admin-API provisioning,
no longer needed).
- hive-c0re/src/dashboard/extra_forges.rs: GET /api/extra-forges?
agent= lists an agent's stored forges by scanning its state dir
(mirrors matrix_accounts.rs's filename-scan listing), POST
/api/extra-forge-account (agent/label/base_url/token/
action=add|remove) stores or removes an account.
- hive-sh4re/priv_proto.rs + hive-priv/main.rs: new
WriteAgentExtraForgeAccount/DeleteAgentExtraForgeAccount priv
requests (adds base_url, writes/deletes a JSON sidecar alongside the
token).
- hive-c0re/src/priv_client.rs: matching wrapper functions.
- frontend/packages/dashboard/src/credentials.{html,js}: FORGES tab is
a per-agent list + add-account paste form (label/base_url/token), no
grant/revoke-from-catalog UI.
- docs/web-ui/dashboard.md: FORGES tab section rewritten.
Supersedes the design in PR #2407 (already approved+green on the old
admin-API model) — opening as a fresh PR against the same issues
rather than force-pushing over the approved one.
gitea-runner registration (hive-ci-prefetch, host-side) sits on the
boot-critical path -- nspawn readiness is gated on the runner
registering, itself a forge + core-token round trip that can wait up
to 60s for the core token. The default ~60s TimeoutStartSec can trip
mid-register (especially right after a .runner purge, since every
boot re-registers from scratch), killing the half-started container
and triggering a restart loop until the token/forge settle. Bump to
180s so one register attempt has room to finish.
The live run-view streamer returns a single snapshot of whatever act_runner
had buffered by poll time. For a job that's still running that's fine (no
persisted log exists yet), but for a job that already finished it silently
truncates wherever the snapshot happened to stop -- the original bug: a
failed nix flake check run returned only the ~90s eval-phase prefix and
dropped the actual build-phase error entirely.
Flip the priority: try the durable persisted-log download first (complete
once it exists), fall back to the streamer only when nothing's persisted
yet (run still live). --step still goes straight to the streamer since the
persisted log is flat and doesn't honor per-step framing.
mara: "no, do split packages for the separate daemons" — instead of
grouping all daemon/harness/MCP bins into one hyperhive-daemon
derivation, each bin (hive-c0re, hive-priv, hive-agent,
hive-agent-mcp, hive-agent-wake, hive-bash-daemon, hive-bash-mcp,
hive-matrix-daemon, hive-matrix-mcp, hive-metric) is now its own
named package + overlay output, matching the existing hivectl /
hive-forge split. harness-base.nix's ExecStart/command lines now
point at the specific pkgs.hive-* each ExecStart needs, and
environment.systemPackages only carries the two bins actually
PATH-looked-up in-container (hive-agent-wake, hive-metric) instead
of the whole bundle.
Agent containers pulled in `pkgs.hyperhive` (packages.default: daemonBins +
hivectlPkg + hiveForgePkg) via environment.systemPackages and every
harness ExecStart. That shipped hivectl (a host-admin CLI dialing the
host admin socket, unreachable from inside a container, wrapped with
wireguard-tools for `hivectl wg`) plus a redundant second hive-forge
copy (already provided separately via hive-forge-tools.nix) into every
single agent's closure.
Expose the existing daemonBins split as packages.<system>.daemonBins
(mara: 'there should be split nix outputs already, use those' — no new
grouping derivation) + a hyperhive-daemon overlay entry, and repoint
harness-base.nix's systemPackages entry and all agent-run ExecStarts
(hive-agent, hive-agent-mcp, hive-bash-daemon, hive-matrix-daemon) plus
the bash/matrix MCP bridge commands at it instead of the full bundle.
nix flake check: daemonBins + agent-base-toplevel + ruth-toplevel all
evaluate cleanly (docs derivation failure is a preexisting dirty-tree
issue, unrelated).
Argus flagged the doc comment overclaiming no risk of a stale
suppression leaking onto a reused task id — narrow the wording to
match the acknowledged race in run_task's completion handler.
A `status` or `run` call whose inline `wait_seconds` poll observes a
terminal task hands the caller the full result in that same tool
response. The completion wake fired unconditionally regardless,
producing a redundant `bash-task-<id>` inbox message for information
the agent already has.
Add a one-shot, in-memory wake-suppression registry in hive-bash-mcp's
runner: `wait_for_task` (shared by both BashRun's and BashStatus's
inline-wait paths) marks a task's wake suppressed the moment it
observes a terminal state; `run_task`'s completion handler consumes
that flag before calling `send_wake` and skips the wake if set.
In-memory only (daemon restart wipes it) — fine, since a task still
running across a restart is separately marked `interrupted` on boot
and gets its own fresh wake. Narrow best-effort race window between
the terminal write and the wake send; acceptable given this daemon's
existing best-effort delivery tolerance elsewhere.
docs/tools/bash.md updated to describe the new suppression behavior.
