* screen: a signature vouches for its change and what it builds ontv3 days1-0/+3
| | | | | | | | | | | | | | | Review finding 5: vouching by (actor, seq) isn't bound to a hash. A member can make a change under another member's actor at a seq that member's signature covers. The change is then taken as vouched, and if it breaks a rule, the honest member is refused as a whole and logged as the one whose own change broke the rules. A signature now vouches for its change and the changes of its actor it builds on: in the document, as before; among received changes, those it reaches through the batch's dependencies. A received change under an actor at a seq whose change the document holds (a signature verified up to it) is a fork: refused as forged, never as its actor's node's, not told back in REFUSALS, and logged with the peer that brought it.
* sync: a member refused as a whole, synced with again once it changed documenttv3 days1-3/+21
| | | | | | | | | | | | A node refusing a member as a whole sent it nothing, and lifted that only when a change of the member's was taken again. But a member that dropped what was refused (REFUSALS) starts its sync sessions over, and a fresh session sends no changes until the other side answers: the two waited for each other, and the member stayed refused. The refusal now notes the member's run and epoch_seq when it began; a member with another document since (it dropped what was refused, or rejoined) is synced with again.
* swarm: changes taken unjudged, dropped (REFUSALS)tv4 days1-4/+15
| | | | | | | | | A node refusing changes a peer brought tells it which broke a rule; the peer judges them itself, and if its rules refuse them too, drops them with all built on them (its document forked without them, a fresh actor), quarantining its own writes among them. Wire version 42. Auth plan M6 (rejoin on taint).
* access: members refused as a wholetv4 days1-0/+8
| | | | | | | | | With signatures required, a member whose own change broke a rule is refused as a whole: sent nothing, shown in /peers (refused), in stats (sync.refusedPeers) and on the dashboard, until a change of its is taken again or the epoch changes. Auth plan M6 (diverged standing).
* access: refused oncetv4 days1-5/+28
| | | | | | | | A refused change is remembered by its hash: offered again it is refused without decoding, judging or logging, so is one built on it, and a peer offering nothing else is answered later each time, up to a minute. Auth plan M6 (re-sending).
* access: signatures requiredtv4 days1-5/+20
| | | | | | | | "signatures": "required": a change counts only once a signature by its committer vouches for it, and waits until then; every node then signs every change it makes. Auth plan M6.
* access: the policy enforcedtv4 days1-2/+31
| | | | | | | | _continuum/access/policy ({"version": 1}) has every node screen every change it receives, on every path changes come in. A policy a node doesn't know stops its writes through the API. GET /admin/refused. Auth plan M6.
* signatures: with sync messagestv4 days1-1/+40
| | | | | | | Sync messages carry, for each actor's writes, the latest signature the sender checked; the receiver checks it once it holds the change. Auth plan M5.
