Drop unused navigation-compose and material3-window-size-class.
alpha19+/beta01 need AGP 9.1 + compileSdk 37, so alpha18 is pinned.

Direct destinations that stay unreachable past the cooldown are now
routed through the VPN tunnel until the network changes. The Home
availability card marks such hosts "via tunnel" and offers a one-tap
"Via VPN" action for the rest.

underlyingNetworkLabel() returned the first non-VPN network from
allNetworks, whose order is unspecified - Android keeps the cellular
network agent alive in parallel with Wi-Fi, so on Wi-Fi the details
sheet could show "Сотовая сеть". Wi-Fi now wins when present (same
precedence as NetworkMonitor's trust decision); cellular is only
reported when no Wi-Fi network exists.
- ConnectionDetailsSheet: session traffic split "via VPN / direct (RU)"
from the native engine counters (userspace mode only; system-routes
mode shows no split - the engine never sees that traffic), public exit
IP + country via cloudflare cdn-cgi/trace through the tunnel, current
underlying network (Wi-Fi + SSID / cellular)
- ConnectionCard: one-glance "N% direct" caption when the RU split moves
traffic directly
- dead direct hosts surfaced in UI: native snapshot of the negative-cache
table via new get_dead_targets (mutex-guarded, sorted by failures) +
JNI getDeadDirectTargets; section on the Routing tab and a badge in the
Home availability card naming dst, failure count, remaining cooldown
and the owning app (from the 2.13.15 owner-attribution cache)
- HomeViewModel: split/exit/deadTargets as separate hot flows; exit
refreshed with the probe round (60s cache), dead targets every round
minSdk 23 flipped AGP's useLegacyPackaging default to false (uncompressed
.so, extractNativeLibs=false): the APK grew 12 -> 23 MB. Updates are
downloaded over cellular, so pin useLegacyPackaging = true; APK is back
to ~12 MB (2.14.0 re-published with the same versionCode, sha updated in
the manifest before any device fetched it).
- minSdkVersion 21 -> 23 (device is Android 17, no other users); jni
Application.mk: APP_PLATFORM android-23 + -DHAVE_SIGWAITINFO (the NDK
sysroot declares sigwaitinfo since API 23, conflicting with strongSwan's
fallback prototype; the system implementation is used now)
- replace the bottom NavigationBar with NavigationSuiteScaffold (bottom bar
on phones, navigation rail in landscape/on tablets); item colors keep the
brand palette via NavigationSuiteItemColors(bar/rail/drawer)
- HomeScreen applies statusBarsPadding itself (the adaptive scaffold no
longer pads the content area)
- predictive back was already enabled (android:enableOnBackInvokedCallback)
Log-driven fixes from the 10-04 diag/charon analysis:
- direct_tcp: negative-cache window now escalates 45s x2 up to 5 min
(Telegram was opening ~3000 connects/h to each of two dead hosts,
waking the radio for every leaked 45s probe); skip the unconditional
fresh-socket retry on ECONNREFUSED (a refusal is deterministic on the
network the socket is bound to; roam-time sockets are already aborted
by reprotect)
- new dead-destination diag line (dst, fail count, cooldown) via JNI
callback when the window escalates or hits every 100th failure
- VpnStateService: double-start guard - a second connect() for the same
profile while a healthy attempt is in flight is ignored (four starters
raced through here within 20 s after the 2.13.14 self-update)
- NetworkMonitor/AutoConnectManager: flap detection (>=2 kind changes in
5 min stretches the auto-connect delay to 10 s; a Wi-Fi flap produced
a 7-second-lived session and a wasted IKE handshake)
- hardcode diag TAGs obfuscated by R8 ("a: update: up to date" ->
"UpdateManager: ..."), same for UpdateInstaller/VpnShortcutManager
Diag/charon logs from 2026-09-30 16:45 showed that after a Wi-Fi->cellular
roam every direct-TCP connect failed asynchronously with EHOSTUNREACH for
minutes, while the IKE socket worked and a Java socket explicitly bound to
the underlying network connected fine: a bare VpnService.protect() left
fresh sockets routed over the vanished network.
- CharonVpnService.protectDirect(fd): protect + Network.bindSocket to the
active non-VPN network (API 23+, best-effort, adoptFd/detachFd)
- charonservice_protect_direct_socket() JNI wrapper; relay and UDP flow
sockets use it at creation
- direct_tcp: one retry on a fresh socket when an async connect fails;
reprotect aborts still-connecting relays (RST) instead of letting the
kernel take ~90s to report the dead route; failures log dst=ip:port
- direct_udp: reprotect closes all flows; they re-open per packet with a
fresh, network-pinned socket
- TUN reader: EBADF after a reauth re-establish is no longer logged
Published as 2.13.10 (versionCode 147).
Replaces the fragment-based UI with a full Jetpack Compose app
(HOME/profiles/routing/settings/trusted networks in Compose, adaptive
brand theming, notification/vector drawables), adds the SHX release
pipeline (build-local.sh, UpdateManager self-update from the S3 bucket,
DiagLog diagnostics rotated into diag.log with crash capture) and the
watchdog/auto-connect/reconnect hardening series.
RU-GeoIP split now has two modes (Routing screen):
- OS routes (default): coarsened complement of the RU list installed
as system routes, bounded by the binder budget (2.12.x behavior)
- Userspace routing (beta): only the default routes point into the
TUN; every packet is classified natively against the exact RU list
(ring-buffer queue, fixed flow tables - allocation-free hot path)
and RU TCP/UDP leaves through protected sockets. TCP is terminated
by a vendored lwIP 2.2.0 (tun2socks model, err_t renamed to avoid
the strongSwan typedef clash, wildcard-port listener patch, asserts
into diag.log). IPv4 addresses are compared in Java's numeric byte
order and ranges sorted natively; direct flows re-protect on roam;
relay errors log errno. Route diagnostics block 12s after connect.
Also: SIM2-crash hardening, connectivity watchdog with wakeup alarm,
profile export, connectivity self-check screen, tests.

Since 5.9.6, the number of half-open SAs includes queued initial IKE
messages. So that number could be higher than the number of managed
SAs, which causes an underflow in the output.
Fixes: b866ee88bf ("ike: Track unprocessed initial IKE messages like half-open IKE_SAs")
The previous code did not synchronize some of the flags, so it was
possible that `cancel()` did not work properly (e.g. no APC queued).
This change uses atomics to set/read the flags, it also avoids using
the global thread lock for synchronization as getting the condvar before
queuing the APC avoids having to sync with `docancel()`. However, to
make sure we don't use a stale and potentially already freed condvar
when the thread is canceled a new lock is added and held until the
condvar has been signaled (using atomics for that member doesn't work as
the ordering rules enforced by atomics can not avoid that the thread in
`cancel()` potentially reads a stale value, or the race between reading
and signaling it).
The protocol has long been replaced by IKEv2 and is officially deprecated
since several years (RFC 9395). As a first step to removing support for
it completely, this makes the configure option disabled by default and
warns users about its use.
There is no reason to keep this around anymore (has been superseded by
TNCCS-2.0 a long time ago). Removed the corresponding test scenarios.
Since this is the last user of libxml, also removed those references.
This was primarily used in our labs to visualize some TNC aspects but
the third-party daemon and frontend we used have not seen any development
in a decade. There never was any industry interest in this protocol
anyway, so just remove it.
Besides the relatively recent update to libsoup-3, this has not seen
much development and lacks several features. There does not seem to be
any advantage over using the curl plugin. So just remove it to reduce
the maintenance burden.
This has not seen any significant changes for years. So it lacks support
for modern algorithms and would require quite some work for an overhaul.
Given that we support several other crypto backends, let's just remove
this to reduce the maintenance burden.
The test scenarios and other references are also removed.
The 7.2 kernel has officially deprecated the interface and it will soon
be removed (support for hardware crypto offload has already been removed).
Also removed the corresponding test scenarios.
This plugin was developed for a customer who had very specific
requirements. It never did anything useful for regular users and
usually caused confusing errors if they enabled it by mistake. So
just remove it.
There is no reason to use Blowfish nowadays. Given that there are some
other plugins that still provide it, there is especially no reason to
maintain this custom implementation. Also removed the two test scenarios
that used the plugin to avoid promoting the use of this algorithm.
This was from a student project that has never been developed further.
And similar to the manager web application it lacks all sorts of modern
standards. So just remove it and the two plugins it relied on.
The test scenario is renamed to avoid confusion (neither of the two
p2pnat scenarios uses medsrv/medcli).
This fixes a potential TOCTOU issue with opening log files. The use of
`chown()` instead of `fchown()` could theoretically allow modifying the
ownership of an unintended file.
The log file now also is not world-readable anymore.
Also, the patch fixes the log groups for the two `(f)chown()` errors.

It might not be a good idea to blindly accept such extensions. A scoped
CRL could be accepted for the wrong scope. So just reject them again.
This reverts commit 126778679f.
The enumerator strictly handles pointers to pointers, so passing a
`u_int` is incorrect on 64-bit platforms.
Fixes: 918e92c4c9 ("Support multiple different public key strength types in constraints")
While for most uses the length is fixed and public (e.g. PRF/MAC outputs),
there are a few (e.g. in xauth-generic) that compare variable length
data.
The previous code directly leaked a differing length by short-circuiting
before comparing anything. While we could limit the comparison by the
minimum length (and call `memeq_const()`), that could still leak the
length because the time will plateau once the secret's length is reached.
Similarly, if the comparison was bound by the longer chunk (would prevent
the use of `memeq_const()`), the length could also be revealed once the
input gets longer than the secret and the time increases.
This changes the semantics of the function by declaring the first
argument the expected/reference secret and the second the variable input.
This strictly makes the function constant-time, bound by the secret's
length. So the length can't be guessed by providing different input (but
if an attacker can trigger the comparison against different secrets, of
potentially known lengths, it might still be possible). If the chunks
are known to have the same length, the order doesn't matter.
Callers of this function have been updated accordingly.
The check only references the original chunk, so for each parsed payload
it checks the same thing. The length of each individual payload is
checked by the parser anyway. So I think this was primarily added for
the IKEv1 "wrong PSK" use case. Let's keep it for now.
Fixes: dd5c3787dc ("Give a hint that decryption failed if payload length invalid")
If the padding was larger than the whole blob, all available bytes were
checked for a match and the blob's length was eventually adjusted and
SUCCESS returned. Due to the underflow this could result in a huge size
that would then get copied. Zero-length padding was also incorrectly
accepted as was padding larger than the block size.
Fixes: 160f4c225d ("moved PEM parsing functionality to its own plugin")
Should be rare that the eap-identity plugin is not loaded when
authenticating clients with EAP. And the second error path will
currently never get used as `process()` always succeeds.
Fixes: 79f2102cb4 ("implemented server side support for EAP-TTLS")
Because `builtin_vsnprintf()` returns the length of the (theoretically)
produced string even if the buffer is too small, the `fwrite()` calls
would read past the buffer. While it rarely happens that log messages
are even close to the current buffer size, it might get triggered by an
overlong IKE/EAP identity or similar.
For `vasprintf()`, the allocation for the complete required length is
now correctly handled (capped at `INT_MAX` as that's what
`builtin_vsnprintf()` can technically return).
Also fixed is an incorrect mapping of the return value of `fwrite()` in
case of an error. While the latter returns the elements written so far,
the expected return value from `vfprintf()` is negative.
