Kristoffer Dalby e26c0059f3 types: add when a node's run of control sessions began 2026-10-28 00:51:39 +00:00
Kristoffer Dalby d59e14b197 state: keep a prefix mapped when no router is available 
Peers keep the routes of an offline or expired router, as on Tailscale.
The previous primary keeps the prefix, else the lowest-ID approver;
never one the prober declared unreachable.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 7daa08e94e policy/v2, state: elect via primaries among online, healthy routers 
Availability tests expiry itself, not only the online flag.
A health change on a via target now triggers a peer recompute.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby fe42e17a30 state: withhold HA probe results only for routers tied to a deferred one 2026-10-28 00:51:39 +00:00
Kristoffer Dalby b95f19e0d8 state: keep probing a lone advertiser while it is unhealthy 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 1864e7a284 hscontrol, types: strip trailing slashes from server_url 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 857e3fe5be db: bound the wait for a legacy hash verification slot 2026-10-28 00:51:39 +00:00
Kristoffer Dalby cbe5883e95 db: reload the credential row after a legacy hash verification 2026-10-28 00:51:39 +00:00
Kristoffer Dalby c827dc8fdc db: disable GORM's prepared statement cache on SQLite 
database.gorm.prepare_stmt is now ignored, with a startup warning.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby e6302ce9b6 policy/v2: refuse check SSH rules with tag sources 
A check asks the source's user to log in again, and a tagged node has
none. Tailscale SaaS refuses the rule; headscale accepted it.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 7fa1aa7d66 policy/v2: limit the destination and port pairs a policy declares 
A grant lists dst and ip apart, so its filter grows with their product.
Refuse a policy over 100,000 pairs, on every parse.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby f2924f39e6 policy/v2: refuse a port list in a grant ip entry 
Tailscale SaaS takes one port range per ip entry; a list was accepted
and expanded. Write each range as an entry of its own.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby a0ae68f22b policy/v2: evaluate policy tests before taking the write lock 
SetPolicy ran the policy's tests under the lock every map response and
node write needs. Run them on a snapshot of users and nodes first.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 350aea66f4 policy/v2: index compiled SSH rules by source for sshTests 
Each check scanned every rule and parsed every principal per login name,
destination and source address. Compile once per run, key each
destination's rules by principal address, and evaluate a name once.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby ea9f099657 policy/v2: parse the compiled filter once per tests run 
The tests evaluator parsed every SrcIPs and DstPorts entry again for
each assertion, source prefix and rule. Parse the filter once per run.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 643ed8bfc6 policy/v2: need every dst node for a tests accept, no range sources 
An accept passes only when each node behind the dst is reached, as on
Tailscale SaaS; a deny keeps its rule. A CIDR, "*" or autogroup:tagged
src names no user or host, so its test fails.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby bda2cb5076 policy/v2: label sshTests failures with the dst alias 
The report goes back to the policy author: name src and dst as written,
one line per dst occurrence, and a dst with no node as not reached.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 649985954f policy/v2: bound the tests and sshTests failure report 
The report printed every failure with the full labels, so its size was
labels times failures. Print 100 lines of 256-byte labels, then a count.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 76bdf3adad policy/v2: refuse autogroup:member as an sshTests destination 
Tailscale SaaS refuses it when parsing; headscale evaluated it.
 2026-10-28 00:51:39 +00:00
Kristoffer Dalby 124efeeaa0 policy/v2: refuse address ranges as sshTests sources 
A CIDR, or a hosts entry holding one, as an sshTests src is refused,
as on Tailscale SaaS. Destinations share the range check.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby a70a567ab7 policy/v2: map login 0 to no local user in SSH rules 
Every rule that maps root now carries "0": "", as Tailscale SaaS writes
it, also when the policy lists "0".
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 1eab82f7f5 policy/v2: write an ACL's repeated destination once 
An ACL that names a destination and port twice wrote the pair twice.
Grants keep their repeats, as on Tailscale SaaS.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby b4b2322182 policy/v2: write a single-address via destination bare 
Via rules wrote every destination with its prefix bits; ACL and grant
rules already drop them for a single address. Both use one formatter.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby c294109190 db: keep only the current policy 
Every write inserted a row and nothing deleted one, while every reader
takes only the newest. Writers store and install under one lock, so an
uncommitted insert cannot outlive the newer row that pruned the rest.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby f24fad2ccc state: install a written policy only after it is stored 
Writers validated by installing the policy live, so a store failure
left a refused or unstored policy enforced. Validate on a throwaway
manager, store, then reload from the stored row.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 3a57f3a6e3 policy/v2: refuse an empty policy 
SetPolicy returned a nil error for empty input it ignored, so the v1
API stored it as valid. Reload skips only the nil "no policy" case.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 3e9dc82f20 policy/v2: resolve tag owners one hop deep 
A user claims only the tags it owns directly, and a tag owns only the
tags that list it, as on Tailscale SaaS. With no walk left, validate
names an undefined owner once, with the tag that lists it.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby bd63cdd767 policy/v2: evaluate sshTests sources through the nodes they cover 
A src was expanded to every address it names, so "*" or ::/0 never
finished. Principals are node addresses: keep those plus one stand-in.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 6d1f582fdf policy/v2: resolve each group once per policy compile 
Group.resolve walked users and nodes for every member at every mention.
Resolve all groups once on a copy of the policy and compile from it.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby b00456eb02 policy/v2: compile SSH rules once and share them across nodes 
SSHPolicy re-resolved every rule and built private principals per node.
Compile the rules once per policy, users and nodes; per node, only
select.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby e1d755bc82 policy/v2: merge rules sharing a source slice without rejoining it 
The rules of one ACL now share one SrcIPs slice; key it once instead of
joining it again for every rule, globally and per node.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 571e4476ca policy/v2: resolve an ACL's sources once for all its destinations 
An ACL compiles to one grant per destination, and each resolved and
rendered the same sources. ViaRoutesForPeer only needs one grant per
ACL.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 64b324f4d4 policy/v2: bound via route steering by the peer's routes 
Include and Exclude held one entry per overlapping dst, and the election
walked them per dst. Keep one entry per route; a peer without routes
returns at once.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 4dcb59d453 policy/v2: refresh clients when a user change drops the last via grant 
SetUsers read needsPerNodeFilter after the recompile cleared it, so
the change was reported as empty and clients kept the via rules.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 200c7b799f state: serialise policy reloads 
Load and install the stored policy as one step, so an older
reload cannot install its document over a newer one.
 2026-10-27 21:32:32 +00:00
Kristoffer Dalby 674c52523b policy/v2: recapture SSH data captures 
Every ssh_results row captured again from SaaS. SaaS now maps login "0"
to no local user in rules that map root, quotes a refused checkPeriod as
written and rewords its tailnet-domain refusal.
 2026-10-27 21:31:36 +00:00
Kristoffer Dalby 90933aef03 hscontrol, servertest: add key list scope golden data 
Read-only and key-making OAuth tokens of each tag set list auth keys
with and without all=true, over admin- and token-made keys of every tag
relation, one admin key made after the token-made ones.
 2026-10-27 21:31:36 +00:00
Kristoffer Dalby 85b9b022a4 servertest: add user role dispatch golden data 
An admin role change under autogroup:admin, mirrored as a user rename;
peers, filter and frames per node per step, and v2 device users.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 791ad5fd2c servertest, state: add node name golden data 
Labels under taken hostnames, case-only renames, hostname changes, long
hostnames and a Service's name; API, peer and self per step, and State
labels as a restart would load them.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 376390ed7c policy/v2, servertest: add policy generation golden data 
One policy over joins, a via router swap, an admin tag, a delete and a
group edit; filter, SSH, peers and routes per step, and the manager
against a fresh one.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 6900fc2182 servertest: add hidden peer and route announcement golden data 
What a node hears of peers it cannot see, and what a router's peers hear
of routes it announces; presence, removals, peers and routes per step.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 3a8d0aacc8 servertest: count map frames per client 
Counts ControlTime events, so frames that leave the netmap as it was,
or that a delta client applies in place, still show.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby bafeb7ebc0 servertest: recapture map delivery golden data 
The probe now bounds snapshot reads and keeps feature refusals as data.
SaaS now sends appc and sshd laptop's unchanged entry on the restore.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 5f01923282 servertest: wait for each replayed join before the next 
Polls start in the background, so a later router could come online
first and keep the global primary SaaS gave the first.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby be8c273504 servertest: count deleted nodes in replayed peer views 
Only nodes still in State resolved to an alias, so a client that kept
a deleted peer passed the peers and route owner checks.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 2a8b614a03 servertest: recapture via HA failover golden data 
The probe now bounds its reads and stops when a step loses data.
Route owners and peers match the first capture at every step.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby a0d6662119 hscontrol, servertest: fail on any unread pending login or expiry entry 
Each map serves one capture, so a misspelled capture name never went
stale.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 254205db54 servertest: require a map on each stream an expiry replay opens 
The cached netmap outlives a stream, so a refused re-poll passed.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby 673a17156e servertest: compare filter and SSH rules in expiry replays 
Changed-or-not alone let empty rules pass for SaaS's new ones.
 2026-10-27 21:31:35 +00:00
Kristoffer Dalby c370d9737e servertest: recapture ephemeral, expiry and pending login golden data 
The expiry file now holds the shared policy, DNS and observer setup.
Outcomes match the first capture; collection was seen one poll earlier.
 2026-10-27 21:31:35 +00:00
