founder	431732396b	fix: apply nft batches in the selected namespace, complete the swap rollback [P0] ... Two release blockers, the first a regression introduced by dd5be47. 1. The anti-torrent batch was applied on the host. Making the rebuild atomic moved it from run_step(transport, ..) to run_nft_batch(script), and run_nft_batch spawned `nft` directly with Command::new. An nft transaction belongs to the network namespace of the process that runs nft, so with the production default apply_in_amnezia_netns = true the sequence became: inspect inside the container, install the table on the host, verify inside the container, fail. The guard was silently ineffective, a stray table accumulated on the host, and the next reconcile could fail on `add table` because the host copy already existed. NsTransport gains run_with_stdin, implemented for all three transports - host, nsenter, and docker exec with -i, which is required or the child sees EOF immediately. run_nft_batch now takes the transport, and both callers pass the one they inspected with. A recording fake transport asserts the script goes through the transport rather than to a host process, which is the regression this could not previously catch. 2. Swap replacement rolled back with the wrong priority and not from every branch. The rollback reactivated with desired.priority - the value that may be exactly what the kernel had just rejected - because the previously active priority was dropped at the match arm and never passed in. The active entry's priority is now carried into replace_active_swapfile and used by the rollback. Three early failure branches also returned without undoing anything: a failed swapoff of the original, a failed rename to .previous, and a failed swapoff of the staging file all left the staging swap active and the transition half-applied, after which the next reconcile tried to unlink a file that was still active and could not proceed. The transition now records what it completed - staging_active, original_active, original_moved, new_installed - and one rollback undoes exactly that much, in an order that never leaves the host without swap: restore the original file, reactivate it at its previous priority, confirm it, and only then release and remove the staging swap. The returned error carries the original cause plus what the recovery achieved. Leftovers from a killed process are no longer removed blindly. A .new or .previous that is still active cannot be unlinked, so it is reported with the swapoff command that clears it instead of failing the same way on every reconcile. Also in this commit, from the same audit: - Requires=docker.service dropped in favour of Wants=. The daemon is built to outlive Docker being down, but Requires= had systemd stop the harness whenever Docker stopped, and Restart=on-failure does not cover a dependency-ordered stop - so the reconnect loop never got to run. - apply_antitorrent_disabled swallowed every discover_target error, not just "no container running". Docker being unreachable or a permission error on the socket reported success for a cleanup that never happened. Only AppError::NotFound is tolerated now. - FstabTransaction::begin asserts /etc/fstab is a regular non-symlink file. read_to_string and metadata both follow links, so a symlinked fstab would be read through and then replaced by the rename, detaching the real file from the path the system boots from. - append_event serialises its read-modify-write behind a mutex; the reconcile loop and the Docker events thread both append and could drop an entry. - tool_exists loses the fallocate, chmod and dd arms, dead since mkswap --file replaced the allocation chain. Docs corrected where they no longer matched the code: findmnt is described as mandatory rather than skippable, the swap creation wording is mkswap --file, and the README package examples use 0.1.6 to match Cargo.toml. Remaining fallocate mentions are explicitly historical ("the previous chain"), which is accurate. Seven tests added: batch routed through the given transport, batch failure reported as such, rollback state defaults and previous-priority carry, active leftovers reported rather than deleted, inactive leftovers cleared. cargo fmt --check, clippy -D warnings, cargo test --locked --workspace --release: 188 + 4 passed.	2026-08-07 05:08:20 +05:00
founder	eea787d6f8	chore: reap docker events, cut per-cycle work, use mkswap --file [P1/P2] ... 1. docker events was leaking zombies. docker_events_loop spawned the child, read its stdout to EOF and returned without calling wait(). Dropping a Child does not reap it, so every reconnect - which happens whenever Docker restarts or the stream ends - left a defunct process behind for the lifetime of the daemon. The reader loop moved into its own function so the wait happens on every exit path, and the exit status is logged rather than discarded. 2. sysctl status still decided ownership with contains(). The destructive paths were fixed earlier, but inspect_sysctl_tuning kept first.contains(MANAGED_MARKER) in the disabled branch, so a file whose first line merely embedded the marker was reported as managed. Diagnostic-only, but it contradicted the rule the rest of the module follows. Now an exact match on the trimmed first line. 3. Swap was reconciled at the traffic interval. ensure_swap ran every reconcile_interval_secs, default 15, and each run spawns swapon --show, sysctl reads, the persistence check and the final verify. A swapfile, its fstab entry and vm.swappiness change when an operator changes them and at no other time, so this was process spawning for state that does not drift. Swap now runs on its own 300-second schedule; traffic and firewall keep the configured interval. The startup reconcile is unchanged, so a fresh daemon still converges immediately. 4. The event log recorded routine success. Every successful cycle appended a line, and appending means reading the whole file, rewriting it and truncating. At 15 seconds that is roughly 17k entries a day, and the entries worth reading were buried among them. Only transitions are written now: a new failure, a failure whose message changed, and the recovery after one. set_ok and set_err report whether the state actually changed, which is what makes that possible. journald still has the full per-cycle picture through the tracing output. 5. Swapfile creation is one command. mkswap --file <path> --size <N>M creates and formats the file, replacing the fallocate → dd fallback → chmod → mkswap chain: four processes, three failure branches, and a window where the file existed but was not yet formatted. util-linux on Debian 13 also handles filesystem-specific requirements - Btrfs in particular - that raw fallocate does not. fallocate, dd and chmod drop out of the required host tools when swap is enabled. cargo test --workspace: 183 + 4 passed. clippy -D warnings clean.	2026-08-07 04:50:57 +05:00
founder	61ce1beb19	fix: make the reboot plan trustworthy and report unreadable sysctl files [P2] ... Three diagnostic defects from the follow-up audit. 1. The reboot plan was entirely best-effort. persist_plan discarded the directory creation, the write and every error. The plan file is the only thing on the host that says when it is going to reboot, so a failed write produced a scheduler sitting on a timer that nothing could report. It now creates the directory, writes through a temp file with sync_all and rename, and returns Result. The plan also outlived its meaning in two places. With reboot.enabled = false the scheduler exited without touching a plan written when it was still enabled, so status kept advertising a reboot that would never happen. And after systemd accepted the reboot request the plan stayed behind, leaving a past timestamp looking pending. Both paths now clear it; an absent plan is the desired end state, not an error. 2. sysctl status turned a read failure into "file absent". inspect_sysctl_tuning used fs::read_to_string(..).ok() for both managed files, so an unreadable file was reported as missing - a diagnostic stating the opposite of the truth, in the module whose whole job is to report drift accurately. Reads now go through ManagedFile::read, which distinguishes absent from unreadable, and an unreadable file produces its own drift reason naming the path and the error. 3. README described the removed ExecStartPre. It still said the service runs ensure-swap before starting the daemon. The daemon performs it as the first step of its own startup sequence. Docs also state explicitly what survives swap.enabled = false, which was implied but never written: the swapfile, its activation and the /etc/fstab entry all remain, so swap comes back after a reboot. Only the vm.swappiness persistence is removed. Acceptance checklist gained seven checks covering the priority-only path not recreating the file, swap remaining active throughout a resize, foreign-swap rollback, the unreadable status, and both reboot-plan lifecycle cases. cargo test --workspace: 179 + 4 passed. clippy -D warnings clean.	2026-08-07 04:18:35 +05:00
founder	322f67f69a	fix(swap): bind ownership to device+inode, restrict swap.path to root-owned roots [P0] ... Two defects that together made the previous ownership model unsafe, and reverse an earlier deviation that the follow-up audit correctly rejected. 1. The sidecar marker identified a path, not a file. Ownership was `<swap.path>.awg2-harness-owned` sitting next to the swapfile, and the check was whether that sidecar existed and started with our marker. Nothing tied it to the file it was supposed to describe. The sequence that loses data: our swapfile is removed by hand, the sidecar survives, an operator puts an unrelated file at the same path - and the next reconcile calls it managed and, if the size differs, deletes it. The claim in the previous commit that a wrong path "can now only fail, never destroy" was wrong. Ownership now lives in /var/lib/awg2-harness/swap-ownership.conf, a root-only directory created 0700, and records version, path, device and inode. A path is not an identity: a file can be deleted and another created in its place, but (device, inode) cannot be reused while our file exists. Classification gained StaleOwnership for "right path, different file", which refuses exactly like Foreign but says which situation the operator is actually in. Only ManagedValid and ManagedWrongSize ever authorise a delete, and that is asserted directly. The record is written after the file exists, from its real metadata, so until it lands the swapfile is not considered managed. The old sidecar is now only ever removed, never read. classify_ownership is a pure function taking the recorded state and the observed identity, so the cases that matter - stale record, record for another path, no record - are unit-testable rather than requiring a Linux filesystem. 2. An arbitrary swap.path was still exploitable. The previous commit kept arbitrary absolute paths and argued the ownership marker was sufficient protection. It is not, and the audit is right to reject it. Between assert_swap_path_is_safe and fallocate/dd/mkswap running, a user who can write the parent directory replaces the final component with a symlink and redirects a root-owned operation. That is a TOCTOU; stat-ing before use cannot close it, because the check and the use are separate syscalls. Paths like /tmp/awg.swap or /home/user/awg.swap made this reachable by any local user. swap.path is now restricted to /swapfile or a file directly under /var/lib/awg2-harness/. Both are root-owned, so the window does not exist rather than being detected. /swapfile is kept so existing deployments need no config change. The deny-list it replaces only ruled out the paths someone had thought of; what actually matters is who can write the parent. Eleven tests: the five classification states, a stale record, a record for another path, the invariant that no refusal state is managed, record round-trip, malformed and unsupported-version records, the newly allowed and newly rejected path shapes. cargo test --workspace: 176 + 4 passed. clippy -D warnings clean.	2026-08-07 04:08:52 +05:00
founder	6643328567	docs+test(wg): column count never identifies an AWG version [P2] ... Both the code comment and the docs said the interface row is "14 columns for AWG 2.0, 28 for AWG 3.0". That reads as a version signal and it is not one. The width of the row is decided by the version of amneziawg-tools doing the printing, not by which protocol parameters the tunnel has configured: AWG 3.0 tools emit the wide row for an AWG 2.0 configuration too, with the newer fields simply zero, empty or (none). Any rule of the form "N columns means version X" is wrong by construction. The classifier never relied on column count for that purpose - it discriminates on the allowed-ips column - so this is a correction to what the code claims about itself and to what the docs would lead a future change to assume. Five fixtures added from the audit's list, all previously uncovered: - AWG 3.0 interface row with header protection disabled: the key column is (none) and the range fields collapse to single values; - an AWG 2.0 configuration read through AWG 3.0 tools, asserted to have the same width as a native AWG 3.0 row and to still be rejected while its peer parses; - a dump containing several interfaces, each with its own peers; - an interface with no peers at all; - malformed rows - truncated, non-numeric handshake, non-CIDR allowed-ips - which must be skipped rather than partially interpreted. Docs also pin what was verified and against which versions, rather than stating it as timeless: AmneziaVPN 5.0.0.5 and the master branches of amneziawg-tools and amneziawg-go at the time of the change. amnezia-awg3 is now described as what it is - not a confirmed official name. AmneziaVPN 5.0.0.5 added AWG 3.0 support but still exposes only Awg and Awg2 container variants. It stays in the example list on purpose, and the reasoning is written down: a name that does not match costs nothing because the search continues down the list, while a name missing from the list produces a silent "container not found". This is a deliberate deviation from the audit's suggestion to build defaults only from names in use today. cargo fmt --check, clippy -D warnings, and cargo test --locked --workspace --release all clean: 163 + 4 passed.	2026-08-06 23:03:10 +05:00
founder	bf43b763cd	refactor(lock): use kernel file locking instead of a hand-rolled PID lock [P2] ... The previous implementation had every failure mode a home-grown PID lock has: - contention was detected by matching the substring "lock already exists" in an error message, so any change to the message would have turned a busy lock into a hard error; - stale-lock recovery removed the file and created it again as two separate operations, so two processes could each decide the lock was stale and each take it; - a reused PID made a live lock look stale, since the check was only whether /proc/<pid> exists; - Drop deleted the lock file, racing with a process that had already opened it and was sleeping on the retry loop - it would then lock a file that no longer has a directory entry, and the next arrival would create a fresh one and lock that instead. Replaced with advisory kernel locking through std::fs::File::try_lock, stabilised in Rust 1.89 and backed by flock on Linux. No new dependency. The kernel releases the lock when the holder exits by any means, including kill -9, so there is no stale state to reason about and no recovery heuristic to get wrong. The PID is still written to the file, but purely as diagnostics - nothing reads it back to make a decision. The lock file is now never deleted. Its presence carries no meaning; only the lock held on it does. That removes the race the old Drop introduced. Five tests: a second acquisition of a live lock fails, timeout reports lock busy timeout, the lock is free again once the guard drops, the file survives release, and a leftover file from a previous run does not block acquisition. Behaviour note for the four call sites (traffic, firewall, sysctl_tuning, swap): timeouts are unchanged, and a process killed mid-reconcile no longer leaves anything that needs cleaning up before the next run. cargo test --workspace: 158 + 4 passed. clippy -D warnings clean.	2026-08-06 22:56:59 +05:00
founder	a9b6e3c15d	fix(systemd): drop the duplicate ensure-swap, use Type=exec and stepped restart backoff [P1] ... awg2-harness.service ran ensure-swap from ExecStartPre while the daemon runs it again as the first step of its own startup. Idempotency kept it harmless, but it cost two locks, two reads of /proc/swaps, two persistence checks, and split the startup failure path across two units so an operator reading systemctl status could not tell which invocation failed. The daemon owns the startup sequence, its error contract and its log stream, so the ExecStartPre is removed. The standalone ensure-swap subcommand is unaffected. Type=simple reports a unit as started the moment systemd forks, before the binary is known to be executable. Type=exec waits for the exec to succeed, so a missing or non-executable /usr/sbin/awg2-harness fails the unit instead of appearing to start. Restart policy: the daemon moves from Restart=always to on-failure, matching the scheduler. A clean exit is deliberate and should not be respawned. For the scheduler this was already load-bearing and is now documented - it exits 0 both when reboot.enabled is false and after systemd accepts the reboot request, so Restart=always would have spun it in a loop on any host with scheduled reboots disabled. RestartSec=10s with StartLimitBurst=5 over StartLimitIntervalSec=60 could exhaust the limit in about 50 seconds, which is easy to hit when the daemon is failing because Docker or the container is still coming up - the restarts burn the budget before the dependency can recover. Replaced with a stepped backoff, 10 -> 20 -> 40 -> 80 -> 160s via RestartSteps=4 and RestartMaxDelaySec=160s, and the limit window widened to 15 minutes with a burst of 10 so a full backoff sequence fits inside it. Both directives require systemd 254+; Debian 13 ships 257. Documented alongside, because it is the same lifecycle contract and had no home in the docs: configuration is read once at process start and a config edit needs a restart of the affected service. daemon-reload is not involved - it applies to unit files, not to the application config. ExecReload is deliberately absent, since adding it without real SIGHUP handling would imply a reload path that does not exist. Unit files are installed from the repo root by tools/build.sh, which already runs systemd-analyze verify on the build host when it is available, so these changes are verified there. Not verifiable in this environment: no Debian, no systemd. Acceptance checklist gained five checks covering unit verification, the restart-required contract, single ensure-swap per start, growing backoff, and the scheduler not looping when reboots are disabled.	2026-08-06 22:54:11 +05:00
founder	e9f0e29f75	refactor: one ownership model for every file written under /etc [P1] ... Two modules wrote into /etc/sysctl.d and did it differently. sysctl_tuning refused to touch a file whose first line lacked its marker and cleaned up on disable. swap wrote /etc/sysctl.d/99-awg2-harness.conf with a different marker, no ownership check at all - an administrator's file at that path was silently clobbered - and never removed it when the module was turned off, so vm.swappiness stayed pinned forever. New module managed_file.rs holds the rules once: - a read that fails is never an absent file; - ownership is Absent / Managed / Foreign, decided by the marker on the first line; - write refuses Foreign, skips when the content already matches, and is otherwise atomic: temp sibling created with create_new, sync_all, mode 0644, rename, directory flush; - remove refuses Foreign and treats Absent as success. Both modules now go through it. sysctl_tuning loses its private write_atomic, ensure_managed_or_absent and remove_managed_sysctl_file_at. The swappiness file moves to /etc/sysctl.d/90-awg2-harness-swap.conf with the marker "# Managed by awg2-harness swap", matching the 90- prefix every other managed file uses. The old path is removed on first run of the new version, but only when it still carries the previous "# Managed by awg2-harness" marker; a foreign file there is left alone and does not fail the migration, since the current file lives elsewhere. Disable semantics are now explicit: swap.enabled = false removes the managed file and does nothing else. Runtime vm.swappiness is deliberately not reset - picking a value would be inventing a policy - and active swap is not deactivated, because merely turning a feature off should not trigger a destructive action. Previously ensure_swap returned early and left the persisted file behind. Also replaced a vacuous test: swappiness_conf_render_is_stable asserted that a string literal equals a format! of the same literal, touching no production code at all. It now exercises render_swappiness_conf, and a companion test proves the rendered file is recognised as managed by the same marker check that guards overwriting it - otherwise every reconcile would refuse to touch its own output. Twelve tests: the three ownership states, refusal to overwrite and refusal to remove a foreign file with content asserted intact, idempotent write, stale temp handling, an unreadable path reported as an error, plus legacy migration in all three cases - ours, foreign, absent. cargo test --workspace: 148 + 4 passed. clippy -D warnings clean.	2026-08-06 22:50:19 +05:00
founder	a895295701	fix(swap): never touch an unowned swapfile, activate before deactivating [P0] ... Two more release blockers in the swap module. 1. Foreign files could be destroyed. swap.path was validated against a blacklist of exact strings. /etc/../etc/fstab is not string-equal to /etc/fstab but resolves to it, and nothing normalized the path or checked the parent chain for symlinks. ensure_desired_swapfile then removed any existing regular file whose size did not match the configured one, so a mistyped or hostile path meant deleting /etc/passwd, an application config, or any other regular file. disable_foreign_swaps additionally deleted foreign swapfiles outright. Ownership is now explicit. A sidecar marker <swap.path>.awg2-harness-owned sits next to the managed swapfile, and inspect_swapfile_ownership classifies the path as Missing, ManagedValid, ManagedWrongSize or Foreign. Foreign is always a hard error - the file is never resized, rewritten or removed. Foreign active swaps are now only swapped off; deleting an administrator's swapfile is not this package's call, and swapoff plus the fstab rewrite already produce the exclusive runtime state. Path validation is split in two. The lexical half rejects relative paths, '.' and '..' components, whitespace, control characters and backslashes, the system path list, and anything under /proc, /sys or /dev; it touches no filesystem, so validate-config stays side-effect free on a host where the file does not exist yet. It runs after '..' is rejected, so the string is already normalized and the blacklist cannot be bypassed. The filesystem half runs just before use and refuses a symlink anywhere in the parent chain, not only at the final component. One deliberate deviation from the audit: arbitrary absolute paths stay allowed rather than being restricted to a fixed managed location. Pinning the path would break deployments that already configured their own, and the ownership marker is the guard that actually prevents data loss - a wrong path can now only fail, never destroy. 2. The migration order left the host swapless on failure. ensure_swap ran disable_foreign_swaps first, then created the swapfile, then activated it. Any failure in fallocate, dd, mkswap or swapon after that first step left the host with no swap at all - on a box provisioned with swap precisely because it is short on memory. The sequence is now a transaction: preflight, prepare the managed swapfile, swapon, verify it actually appears in the active list, and only then swapoff the others, rewrite fstab, apply swappiness and verify. Nothing destructive happens until the replacement is confirmed live. The one unavoidable gap is deactivating our own swap to resize it, which cannot be done in place; foreign swap stays up throughout. chmod 0600 now also happens before mkswap, so the file is never briefly world-readable while it already holds swap structure. config.rs no longer carries its own copy of the path blacklist and calls the shared validator. Twelve tests: the four ownership states, refusal to recreate a foreign file with its content asserted intact afterwards, '..' traversal, dangerous and virtual paths, whitespace and control characters, relative and directory paths, a missing parent directory, an accepted chain, and a symlinked parent (unix only). Docs updated: IMPLEMENTATION_SPEC section 17 gained the ownership table, the ordered transaction and the path rules; CONFIGURATION and the acceptance checklist gained the operator-facing constraints and nine checks. cargo test --workspace: 136 + 4 passed. clippy -D warnings clean.	2026-08-06 21:07:55 +05:00
founder	549fbcae31	fix(swap): make the /etc/fstab rewrite transactional [P0] ... Two release blockers, both in the most destructive operation the package performs. 1. An unreadable /etc/fstab was treated as an empty one. let content = fs::read_to_string(fstab_path).unwrap_or_default(); PermissionDenied, an I/O error, a damaged filesystem and "file absent" all collapsed into an empty string. The rewrite then emitted a fstab containing only the managed swap line and installed it atomically and successfully, dropping the root and boot mounts. Consequence: a host that does not boot, guarded by one unwrap_or_default. The same masking was present in read_fstab_swap_entries, so an unreadable fstab was reported by status as "no swap entries", which reads as healthy drift-free state. 2. The backup was best-effort. let _ = fs::write(bak_path, &content); If it failed, the rewrite proceeded anyway. IMPLEMENTATION_SPEC and the acceptance checklist both asserted the backup exists. The scenario where the backup fails is exactly the scenario where it is needed. New module fstab.rs owns the operation: - read_required distinguishes NotFound from every other error and fails on both. A missing /etc/fstab on Debian is an anomaly, not a blank slate, so it is never created; - a blank candidate is refused outright; - the backup is mandatory and flushed before the temp file is created, so there is no window where the target is about to be replaced and no recovery copy exists; - two copies are kept: .awg2-harness.bak is the state before the current rewrite, .awg2-harness.original is written once with create_new and holds the host as it was before this package first touched it; - the temp file is a sibling of the target, created with create_new, sync_all'd, and inherits the original permissions; a stale temp from a killed run is removed explicitly rather than reused; - the candidate is validated with findmnt --verify --tab-file before the swap. The step is skipped when findmnt cannot be spawned; a rejection is fatal; - commit is an atomic rename followed by a directory fsync; - after the rename the target is re-read and compared to what was written. A mismatch restores the backup and fails. Also fixed: render_fstab_line interpolated the path raw. fstab fields are whitespace-separated, so a space or tab in swap.path would shift every following column. Paths now go through octal escaping (\040, \011, \012, \134). Ten tests, all portable - the "unreadable but present" case is exercised by pointing the reader at a directory, which fails as a non-NotFound error on every platform. Covered: unreadable target is an error rather than an empty file, missing target is an error, backup failure leaves the target byte-identical, blank candidate refused, unchanged candidate is a no-op that writes no backup, the pristine copy survives repeated rewrites, a stale temp does not block commit, and field escaping. Docs updated: IMPLEMENTATION_SPEC section 17 gained the full rewrite contract, the acceptance checklist gained seven checks including the two failure modes above. cargo test --workspace: 124 + 4 passed, ten new. clippy -D warnings clean.	2026-08-06 21:02:38 +05:00
founder	dbceda5c13	refactor(firewall): split firewall.rs by subsystem, collapse duplicated test fixtures ... firewall.rs held two subsystems that share nothing but the nft command layer: the host INPUT firewall, applied in the host namespace and owning inet awg2_host_firewall, and the anti-torrent guard, applied in the namespace chosen by config and owning inet awg2_harness. The split follows that boundary rather than an inspect/apply one: firewall/mod.rs apply_firewall, namespace selection, shared table constants firewall/nft.rs text normalization and the nft command wrappers firewall/host.rs host INPUT firewall and its 5 tests firewall/antitorrent.rs connection-count guard and its 6 tests Production logic is unchanged. Function sets before and after are identical: 25 against 25, verified by extracting names from the old blob and the four new files and diffing. Not a pure move in one respect, stated here so it is not a surprise in review: the test module contained four near-identical 45-line Config literals, about 180 lines of copy-paste, differing only in the single field each test actually cared about. Carrying four copies into the new files would have knowingly propagated the duplication, so they collapse into one test_config() helper in firewall/mod.rs that tests mutate. This is why the four files total 875 lines against the old 890 despite gaining doc comments. Doc comments now record the reasoning that was only implicit before: why nft output is compared after normalization (rendering differs across versions - quoting, comma-separated ct state lists, brace layout), why the host firewall batch never contains a delete (a partially applied INPUT chain could lock out SSH), why ct state new is load-bearing in the anti-torrent rule, why connlimit_state_present accepts two renderings, and why the anti-torrent rule defaults to the container namespace. IMPLEMENTATION_SPEC section 3 is updated: it described the old flat layout and carried the split as an unfulfilled intention. Both traffic and firewall now match what it documents. cargo test --workspace: 110 + 4 passed, unchanged count. clippy -D warnings clean.	2026-08-06 18:51:31 +05:00
founder	84275d0fe4	status: deduplicate the healthy and degraded paths, keep the System block contiguous ... print_status and print_degraded_sections carried four byte-identical blocks - host firewall (25 lines), anti-torrent (24), last actions (9) and recent events (10) - plus a Conntrack block that was the same logic assembled differently and a Traffic desired block of four printlns. Roughly 80 lines of copy-paste with no test covering either copy, so a format change applied to one path would have silently diverged from the other. The divergence would only ever be visible while the container is down, which is the worst moment to discover the diagnostic output is wrong. Every shared section is now one function called from both paths: print_traffic_desired_section, print_host_firewall_section, print_antitorrent_section, print_conntrack_section, print_last_actions_section, print_recent_events_section. The file already had this shape for print_swap_status and print_reboot_section; the pattern is now followed consistently. The Docker/Amnezia port path block keeps two variants because they genuinely differ - real values against unknown - but the shared FORWARD ownership note is a single constant. The runtime state paths were also duplicated across modules: status.rs re-declared the literals that daemon.rs already owns. daemon::LAST_STATE_FILE and daemon::EVENTS_FILE are now pub and reused, and the recent-events window is a named constant instead of a bare 10. Ordering fix in the same function: print_network_tuning_status ran between the service line and the container lines, so container/container_id/pid/netns/interface appeared under the "Network tuning:" header at the same two-space indent as its fields. Container identity is now printed inside the discovery match, before any other section opens, in both the healthy and degraded paths. Field names are unchanged; only the order of two blocks moved. IMPLEMENTATION_SPEC section 15 documented the old order and is updated. print_degraded_sections returned anyhow::Result<()> while never failing; it returns unit now. status.rs: 645 -> 602 lines. cargo test --workspace: 110 + 4 passed. clippy -D warnings clean.	2026-08-06 18:41:39 +05:00
founder	d98ade42ce	docs: unify language contract to Russian and reconcile the spec with the code ... The docs folder had drifted into a mixed-language contract: IMPLEMENTATION_SPEC.md was entirely in English while the rest was Russian with English headings. Prose is now Russian throughout; English is kept only where it is technically load-bearing (commands, tool output, config keys, file/module/table names, tc handles) and for terms with no settled Russian equivalent in this context (drift, reconcile, peer, namespace, handshake). docs/README.md now states that contract explicitly. Rewriting the spec surfaced several places where it described intent rather than the code. Corrected against traffic_core/src: - module layout: the spec showed traffic/ and firewall/ as directories with model/inspect/apply submodules. They are single files, and sysctl_tuning.rs was missing from the tree entirely. - data model: Peer was documented as carrying public key, handshake and counters. It carries only ipv4; runtime state lives in a separate PeerRuntime, and there is no desired-state struct at all - it is derived inline from config plus sorted peers. RuntimeTarget.netns_path is a String, not a PathBuf. - interface detection: the spec listed a third step taking the first non-loopback interface with an IPv4 address. No such fallback exists; detection bails with an explicit error, which is safer and is now documented as deliberate. - reconcile: the pseudo-flow folded firewall into reconcile_traffic. They are two independent reconciles with separate locks. - locking: only traffic.lock was documented. There are three locks, and sysctl_tuning.lock has a 30s timeout rather than 10s. Stale-lock recovery via /proc/<pid> was undocumented. - sysctl_tuning: the module also manages /etc/modules-load.d/90-awg2-harness-bbr.conf when BBR is active, and refuses to touch either managed file without its marker. Both docs and the acceptance checklist claimed only the sysctl.d file was written. - status contract: the documented output was outdated. All 15 printed sections are now listed in the order status.rs emits them, including the degraded path when no container is found, and the fact that the Network tuning block is printed between the System service line and the container lines. - swap: size was documented as a constant 2048 MB instead of swap.size_mb, and the /etc/fstab.awg2-harness.bak backup was undocumented. - apply/verify: the tolerated-error lists are now the actual closed sets from the code. Acceptance checklist gained checks for the daemon startup failure policy (sysctl/swap fatal, traffic/firewall not), lock contention and stale-lock recovery, degraded status, the modules-load file, and the marker guard. The stale host wg requirement was dropped from its host-tools item. Every path, table, counter and log string quoted in the docs was verified to exist in the source. cargo test --workspace: 110 + 4 passed.	2026-08-06 16:45:00 +05:00
founder	16214f3c66	AmneziaWG 3.0 readiness: centralize wg CLI contract, drop dead host-side fallback ... Peer discovery is now the single owner of how wg is invoked and parsed. wg.rs: - resolve the binary through ordered amnezia.wg_binaries (default [awg, wg]); awg is the real binary in the official image and wg is a symlink to it, so awg is tried first and wg stays for plain WireGuard containers. No probe call: resolution is a property of the command being run anyway. - drop the nsenter fallback. AmneziaWG is userspace and its UAPI socket lives under RUNSTATEDIR/amneziawg/ in the container mount namespace, while host wireguard-tools looks under /var/run/wireguard/. nsenter -n enters only the network namespace, so that path could never return peers. - classify dump lines structurally instead of by column count. The AWG interface line is longer than a peer line (14 columns on AWG 2.0, 28 on AWG 3.0) and its handshake/rx/tx positions hold junk-packet sizes that parse as integers, so only the allowed-ips column discriminates. Column 1 of an interface line is the device private key, which the previous heuristic rejected only incidentally. - fix allowed-ips parsing: `show all allowed-ips` separates a peer's addresses with spaces, not commas, so peers with more than one allowed IP were shaped on their first address only and the rest ran unlimited. - collapse the three duplicated /32-in-CIDR filters into one tokenizer shared by the allowed-ips, dump and pretty-print parsers. config.rs: - add amnezia.wg_binaries with serde default, validated as bare command names (non-empty, no whitespace, no path separators) since they execute inside the container. Existing deployed configs keep parsing unchanged. - remove host wg from the required-tool preflight. It gated daemon startup on wireguard-tools for a code path that produced nothing. status.rs: - discover peers once instead of twice per status call and degrade gracefully like the neighbouring sections instead of aborting the whole output. Tests: real AWG 3.0 / AWG 2.0 / plain WireGuard interface-line fixtures, AWG 3.0 range keepalive, space-separated allowed-ips, binary resolution order, and a test that parses and validates the shipped config.example.toml.	2026-08-06 15:32:26 +05:00
