All three relay checks filter themselves out of the candidates with id !=
ignoreId, so nothing ever compared an AmneziaWG row's own WireGuard listen port
with the relay port its own id derives. Saving a row on that exact port left the
embedded device (UDP on the inbound's listen address, amneziawgnet/device.go:137)
and its injected relay (TCP and UDP on 127.0.0.1, amneziawgnet/relay.go:47-61)
bound to the same UDP port, so whichever loses the race dies -- and when the
relay loses it, Xray refuses the whole config and takes every other protocol on
the host with it. The first AmneziaWG inbound on port 65101 was enough to reach
it: id 1 derives exactly that port.
The row now states the rule its three siblings do: it owns the slot its id
derives. A node-hosted row still keeps its own port, since it binds no relay on
this host.
TestAddInbound_AmneziawgRefusesItsOwnRelayPort and
TestUpdateInbound_AmneziawgRefusesItsOwnRelayPort fail without this -- both were
watched red first -- and pin the two separate call sites, AddInbound's post-Save
block and checkPortConflictTx's ignoreId > 0 block.
* test(amneziawg): pin that a disabled row still owns its relay slot
checkAmneziawgnetSocksConflict filters enable = true, so a disabled AmneziaWG
row is not a candidate when an ordinary inbound's configured port is validated.
SetInboundEnable then flips the column with no port check, so enabling that row
later puts a second inbound on 127.0.0.1:65101 and Xray refuses the whole config.
Expected red on this head; the fix follows.
* fix(amneziawg): count a disabled inbound as owning its relay slot
The forward port check filtered its candidates with enable = true, so a disabled
AmneziaWG row was invisible when an ordinary inbound's configured port was
validated. Nothing else covered the gap: the relay is not a database row, and
SetInboundEnable flips the column with no port check, so re-enabling that row put
a second inbound on 127.0.0.1:65101 and made Xray refuse its whole config,
taking every other protocol on the host down with it.
A row owns the slot its id derives for as long as the row exists, which is the
rule the reverse-direction check already follows. TestCheckPortConflict_
DisabledAmneziawgStillOwnsItsRelaySlot fails without this, on a test-only head
whose go-test run failed on exactly that test, and passes with it.
* test(amneziawg): drop the disabled-row case that asserts the reversed rule
TestCheckPortConflict_AmneziawgnetSocksRelayIgnoredWhenDisabled stated, in its
name and its doc comment, that a disabled AmneziaWG inbound's port must not
block anything -- the rule the parent commit reverses. It also never reached the
predicate it named: its fixture seeds Settings: {}, which
amneziawg.InstanceFromInbound rejects on parsed.Server == nil one statement
before the enable column is read, so it passed with or without the filter.
Leaving it would document both rules for the same operator state with nothing
failing to flag the contradiction. The rule this PR pins is covered for real by
TestCheckPortConflict_DisabledAmneziawgStillOwnsItsRelaySlot, whose fixture
carries a qualifying server block and an enabled peer.
* fix(amneziawg): wrap the relay port window instead of refusing ids past it
An AmneziaWG inbound's loopback relay port is SOCKSBasePort + row id, and
AddInbound refused any id that pushed it past 65535. The inbounds table is
AUTOINCREMENT, so an id is never reused and the counter is only reset when the
table empties: the 435-port window was a lifetime budget, and a database that
had ever created more inbounds could never create another AmneziaWG one --
the reporter's counter sits at 70350, so the protocol never worked there at all
(#6537).
Ids now wrap into the same 435 ports, which leaves every id up to 435 with the
exact port it had, so no existing row, relay or generated config moves.
Wrapping makes the id -> port map non-injective, and nothing compared two
derived relay ports before -- two relays on one port would leave Xray with a
duplicate listen and refuse to start, taking the whole panel's proxy down.
checkAmneziawgnetSocksRelayCollision now refuses a create or an edit whose
derived port another local AmneziaWG row already owns, disabled rows included:
a row owns its slot for good, and enabling it later re-runs no port check.
* test(amneziawg): give each relay-window fixture its own client email
Every fixture built the same client email, and an email is unique across the
whole panel, so AddInbound refused the second create with "Duplicate email"
before either new guard ran -- CI exercised neither the wrap nor the collision
refusal. Each fixture now derives its email from its own tag, which is what the
tag already exists for.
* fix(amneziawg): say relay port in the relay conflict message
A refusal that named the port of the automatic loopback relay read as if the
named inbound listened on an unrelated port -- its own port is the WireGuard
one. portConflictDetail now carries Relay, and both messages that report a
derived relay port say "relay port N"; messages that report a configured port
render byte-for-byte as before.
* test(amneziawg): pin that a node-assigned inbound owns no relay slot
A row adopted from a node carries a NodeID and the protocol it arrived with
(inbound_node.go:737), yet injectAmneziawgnetSocks skips it, so it binds no
loopback relay. The gate this PR added to checkPortConflictTx never looked at
NodeID, so editing such a row can be refused for a slot it does not own.
Expected red on this head; the fix follows.
* fix(amneziawg): skip the relay guards for node-assigned inbounds
Round-2 review finding: the gate this PR added to checkPortConflictTx keyed on
inbound.Protocol alone, so it also ran for a row adopted from a node. Such a row
carries a NodeID and gets no loopback relay -- injectAmneziawgnetSocks skips it
and the desired-instance query is node_id IS NULL -- so it owns no slot and can
collide with nothing, yet editing it was refused with "relay port N ... already
used by inbound '<local>'", naming a port the edited row never binds.
Wrapping made this visible: before it, an adopted id above 435 derived a port
above 65535 that no row could hold, so the pre-existing reverse check under the
same gate could not fire.
Both call sites now require NodeID == nil, matching the local-only predicate the
forward check already used. TestCheckPortConflict_NodeAssignedAmneziawgOwnsNoRelaySlot
fails without this, with the exact false refusal, and passes with it.
