Subject: [PATCH 01/37] Bookworm migration: nftables, IFB QoS, Python 3.11, IPS
 and build fixes

- ut-uvm-update-rules.sh: nftables tune table (replaces iptable_tune kernel patch)
- qos-status.py: IMQ to IFB device migration + parse fix for trailing newlines
- uvm wrapper: suppress iptable_tune modprobe warning on bookworm
- ut-force-time-sync: add 30s timeout to prevent boot hang
- i18n_helper.py: codeset + lgettext deprecation fix for Python 3.11
- captive-portal handler.py: lgettext + imp module + form bytes fix for Python 3.11
- captive-portal logout.py: lgettext deprecation fix for Python 3.11
- IPS suricata_conf.py: ruamel.yaml text_type compatibility for Python 3.11
- IPS suricata_signature.py: Python 3.11 regex fix (re.IGNORECASE)
- libnetcap: conntrack netlink compatibility for kernel 6.1
- debian/control: bookworm dependency updates
- buildtools/jars.rb: OpenJDK 17 path updates
- build-order.txt: updated for bookworm

Subject: [PATCH 03/37] IPsec VPN: fix VTI tunnel teardown and L2TP mark rule
 errors

Add error suppression to IPsec updown scripts to prevent cascading
failures during tunnel teardown when routing tables or iptables rules
don't exist. Without this fix, disabling the IPsec app while VTI
tunnels are active leaves stale routes that break network connectivity.

P0 — IPS suricata config generator broken on trixie:
intrusion-prevention/.../suricata_conf.py uses ruamel.yaml's legacy
module-level load()/dump() APIs which were removed in 0.18 (trixie
ships ruamel.yaml 0.18+). Without this fix
intrusion-prevention-create-config.py exits 1 silently → suricata
runs with NFQUEUE=0, no IPS detection. Migrated both load and dump
to YAML(typ='rt') instance API, preserving preserve_quotes,
version=(1,1), and explicit_start. Validated end-to-end on
192.168.56.155: NFQUEUE=2930 systemd drop-in generated, suricata.yaml
rule-files updated, 27738-line ngfw.rules loaded.

Phase G trixie porting (12 source files):

build-order.txt: . bookworm → . trixie

buildtools/buildtools.rb: prefer openjdk-21 over openjdk-17 over -11.
Trixie ships JDK 21 in main; 17 stays as fallback for bookworm builds.

buildtools/target.rb + rakefile: Ruby 3.x deprecation —
File.exists? → File.exist? (3 occurrences total). exists? was
removed in Ruby 3.2; trixie ships Ruby 3.3 default.

debian/control:
- openjdk-17-jdk-headless → openjdk-21-jdk-headless |
  openjdk-17-jdk-headless build-dep alternative.
- untangle-app-virus-blocker Depends: add untangle-kernel-modules-trixie
  as the first alternative (matches new
  untangle-kernel-modules-trixie-amd64 package shipped in ngfw_pkgs
  commit aa164ae57).

libnetcap/src/netcap_init.c: add 6.12. kernel detection alongside
existing 6.1. and earlier branches. Sets ip_saddr=27, ip_sendnfmark=28,
is_new_kernel=612 — same offsets as 6.1 since the cmsg layout from
patches 0002/0004 carries forward unchanged in 6.12.

uvm/hier/.../login_tools.py + ut-textui.py + web/auth/index.py +
unit_tests/test_web_auth_index.py: Python 3.11+ string handling
fixes (gettext lgettext fallback, importlib.util replacing imp).

debian/changelog: 3 auto-build entries from local trixie rebuilds
(2026-05-11). Versions are valid (proper timestamp.commit format),
not stubs. Noise that the next build pipeline will subsume.

Validated: round-15 trixie ISO install on 192.168.56.137 ships these
patches; UVM starts; IPS infra (NFQUEUE bound, rules loaded);
virus-blocker dep chain resolves via untangle-kernel-modules-trixie.

Subject: [PATCH 08/37] NGFW-15749: drop -extensions from openssl req in
 cert-gen scripts (OpenSSL 3.5)

Trixie OpenSSL 3.5 rejects authorityKeyIdentifier=keyid,issuer:always when
applied via `openssl req -extensions <section>` (no issuer cert at CSR time).
OpenSSL 3.0 (bookworm) silently tolerated this. CSR never written, paired
`openssl ca` then fails, cert never produced. Both scripts lack set -e so
failure is masked and the app starts broken.

Fix: remove -extensions from the req lines. Paired `openssl ca -extensions`
calls keep the extensions at signing time where AKI computation works.

openvpn-generate-certs: 1 site (server cert).
ut-certgen: 4 sites (REQUEST, APACHE, SERVER, MITM modes).

Validated on trixie 192.168.56.155: openvpn server cert regenerates and
daemon starts cleanly; SSL Inspector forges per-flow MITM leaf certs and
web filter renders the block page for https://www.beer.com (Alcohol/Tobacco).

No effect on bookworm/bullseye (lenient OpenSSL 3.0 silently skipped these).

Subject: [PATCH 09/37] NGFW-15749: move UDP QoS connmark save into
 ut-uvm-update-rules.sh

The connmark-save rule for UDP packets carrying QoS priority bits was
emitted by sync-settings/300-qos as `nft insert rule inet tune queue-to-uvm
... ct mark set mark`. But it raced against 010-flush which deletes the
inet tune table at the start of every 960-iptables run; 300-qos then ran
before 800-uvm (= this script's symlink) recreated the table, so the
insert silently failed and the rule was never installed. UDP-heavy QoS
deployments would see priority class flap per-packet on long-lived flows
(DNS, RTP, video, gaming) instead of being inherited from conntrack.

Move the rule into ut-uvm-update-rules.sh, in the same code block that
creates the queue-to-uvm chain. Single owner, no race possible. Gated by
/usr/share/untangle/conf/qos-enabled flag managed by qos_manager.py.

Subject: [PATCH 11/37] NGFW-15749: trixie Dockerfile add safe.directory '*'
 for git 2.47
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trixie's git 2.47 enforces safe.directory checks stricter than bookworm's
git 2.39. Bind-mounted /opt/untangle/build inherits host-side ownership
that triggers "dubious ownership" inside the container, making `git log`
return empty. pkgtools set-version.sh derives the timestamp from that
git log output, so empty timestamps produce malformed debian/changelog
trailers, breaking libapache2-mod-python setup.py with InvalidVersion.

Fix is container-local (safe.directory '*' system-wide) — root cause is
the Docker image, not pkgtools.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fakeroot's default SysV semaphore backend hangs indefinitely under
Travis CI's restricted Docker IPC namespace, wedging do-build after
the post-build dput on every package. Local Docker setups (full IPC
access) don't trigger this, which is why the bug only surfaced on CI.

The TCP backend uses sockets instead of SysV IPC and is fully
compatible — same fakeroot semantics, just a different transport.
libfakeroot-tcp.so is upstream-shipped, no extra package needed.

Subject: [PATCH 13/37] NGFW-15749: NO_CLEAN=1 to skip fakeroot cleanup hang on
 Travis trixie
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Same workaround as ngfw_pkgs 6aa95e6e3 / ngfw_hades-pkgs de1cb997 /
ngfw_vendor-pkgs a6b81b7 — fakeroot (both SysV and TCP backends) hangs
in Travis Docker IPC during post-build cleanup, killing the job after
10 min no-output. NO_CLEAN=1 skips the cleanup block.

Subject: [PATCH 14/37] NGFW-15749: Dockerfile.trixie-base export keyring as
 .asc for sqv

trixie's sqv (apt-key replacement) rejects keybox-format .gpg files.
Export ASCII-armored .asc so apt accepts the untangle archive key.
Mirrors the fix shipped in ngfw_pkgs untangle-archive-keyring
(commit aa164ae57). Without this commit, any future clean rebuild of
the trixie base image re-introduces the keybox bug.

See memory: trixie-keyring-sqv-fix Fix #2 (export --armor).

Subject: [PATCH 15/37] NGFW-15749: WebrootQuery raise BctidClientReadTimeout
 5000 -> 30000

bctid Pulse first-install was caught in a cache-wiping restart loop when
the upstream resolver silently drops AAAA queries (VBox NAT 10.0.2.3,
some consumer routers). glibc parallel A+AAAA blocks ~15s; prior 5s
read timeout fired first, declared Pulse dead, triggered
'systemctl restart untangle-bctid' which wiped bctid's resolved-IP
cache and re-entered the same DNS stall.

30s lets the first lookup complete. Once bctid caches the IP all
subsequent queries are sub-millisecond, so the slow path is first-
install only and does not affect steady-state performance.

Subject: [PATCH 16/37] NGFW-15749: SSL Inspector disable TLSv1 and TLSv1.1 for
 JDK21 compat

JDK21 (trixie) rejects the entire JSSE protocol list passed to
SSLEngine.setEnabledProtocols() if TLSv1 or TLSv1.1 are included,
breaking SSL Inspector for ALL HTTPS traffic, not just legacy sites.

Three coordinated changes so neither fresh installs, upgrades, nor a
user re-enabling the UI toggle can land in the broken state:

1. SslInspectorSettings: flip constructor defaults for
   client_TLSv10/11 and server_TLSv10/11 from true to false.

2. SslInspectorApp.preInit(): bump settings version 3 -> 4. Add v3->v4
   migration that force-flips legacy TLS flags to false on upgrade
   from bookworm/bullseye, where the prior True defaults would
   otherwise persist and brick SSL Inspector.

3. SslInspectorManager.generateProtocolList(): defensively strip
   TLSv1/TLSv1.1 from the protocol list regardless of the UI flag.
   The UI fields remain present (settings schema compatibility) but
   become dead controls. Flipping them on now produces a WARN log
   instead of breaking ALL HTTPS through the appliance.

Customers needing to MITM a legacy-TLS-only intranet server should
add an SSL Inspector rule with Action=IGNORE for that destination,
which bypasses JSSE entirely and passes the encrypted bytes through.

Validated on trixie .123: footgun engaged (client_TLSv10=true,
server_TLSv11=true) -> WARN logged 3x -> github.com HTTPS still
returns 307 web-filter blockpage (MitM succeeded, JSSE accepted the
filtered protocol list).

Subject: [PATCH 17/37] NGFW-15749: IPS guard synchronizeSettingsWithVariables
 against empty get-config output

On first install (and on first UVM restart post-upgrade), sync-settings
may be mid-rewrite of /etc/suricata/suricata.yaml when
intrusion-prevention-get-config.py --variables runs, producing empty
output. The split(\"\\\\r?\\\\n\") on \"\" returns [\"\"] (length 1) ->
loop body runs once -> \"\".split(\"=\") also returns [\"\"] (length 1)
-> variableLine[1] throws IndexOutOfBoundsException, settings_NN.js
never persists, UI shows install fail.

Reproduced on fresh trixie .123 install at 12:51:41 (app-26 install
crashed). Retry at 12:55:20 (app-27) worked because the race window
had closed. Same race is reachable on upgrades when post-upgrade
sync-settings and IPS reload happen close together.

One-line defensive guard skips empty/malformed lines. Happy-path
behavior unchanged.

Subject: [PATCH 18/37] NGFW-15749: ut-upgrade.py add Trixie target helpers +
 kept-back tolerance

Builds on the cherry-picked NGFW-15672 bookworm helpers. Mirrors the same
detect/pre/post pattern for the bookworm->trixie hop, plus a kept-back
tolerance refactor required to survive transitional packages mid-upgrade.

- check_upgrade() refactored to return distinguishable codes
  (0=clean, 1=kept-back, >1=real apt error). Caller decides whether
  kept-back is fatal. Existing bookworm path keeps abort-on-kept-back.

- is_trixie_upgrade() detects via apt sources + running kernel + a
  fixup-done flag file at /var/lib/untangle-vm/.trixie-upgrade-fixups-done
  so post-reboot reruns are idempotent.

- pre_upgrade_cleanup_trixie() pre-installs openjdk-21-jre-headless.
  Trixie untangle-vm needs JDK21 for SSL Inspector compat (afe4c8650a)
  but its Depends doesn't hard-pull it in, so apt would otherwise keep
  stale openjdk-17 and SSL Inspector v3->v4 migration could misbehave.

- post_upgrade_fixups_trixie() waits 30s for the deferred postinst
  daemon-reload cascade (multiple packages each call systemctl
  daemon-reload, cumulatively auto-restarting UVM) then issues a clean
  stop+start of untangle-vm. The cascade-triggered restart hits a
  JDK21+jabsorb parallel-load race where MarshallingModeContext.pop()
  throws NoSuchElementException and 3 apps fail to init (observed:
  tunnel-vpn, intrusion-prevention). Clean restart cures it.

- Main flow integrates trixie path via elif on bookworm_upgrade and
  conditional kept-back handling.

Subject: [PATCH 19/37] NGFW-15749: ut-upgrade.py gate REFRESH COLLATION behind
 PG15+

REFRESH COLLATION VERSION is PG15+ syntax. On a direct bullseye->trixie
upgrade PG13 may still be serving on socket 5432 (PG17 package installs
but its cluster isn't auto-created when PG13 already owns the port), so
the three unconditional ALTER calls in post_upgrade_fixups_trixie emit
harmless but noisy syntax errors into the upgrade log.

Query server_version_num before the ALTERs and skip them with a log
line when PG < 15. REINDEX is left unconditional (valid on all PG
versions and still useful after the glibc 2.36 -> 2.41 sort change).

Affects only post_upgrade_fixups_trixie callers (is_trixie_upgrade()
True path); bullseye-routine, bookworm-routine, and bullseye->bookworm
flows are bit-identical to before this change.

Subject: [PATCH 20/37] NGFW-15792: ut-upgrade.py trixie helper parity with
 bookworm + auto-reboot

Add missing pre/post-upgrade steps that the trixie helper omitted, found
during bullseye->trixie direct validation on 2026-05-26 (.175 ended up with
no nft binary -> no inet tune table -> no NFQUEUE divert -> every pipeline
app silently inspected zero traffic despite loading cleanly).

pre_upgrade_cleanup_trixie():
- Pre-install nftables. Required by ut-uvm-update-rules.sh which wires the
  inet tune table + NFQUEUE divert (queue 1981/1982) for the entire NGFW
  userspace inspection pipeline. On bullseye->trixie direct, bullseye uses
  iptables-legacy and never had nftables installed; no trixie package
  hard-depends on it, so apt won't pull it in. Mirrors the bookworm helper.
- Purge wireguard-dkms (trixie kernel 6.12 has wireguard built-in).
- Persist 'ifb' to /etc/modules so QoS survives reboot.

post_upgrade_fixups_trixie():
- modprobe ifb + create ifb0 device.
- nft list ruleset log dump.
- nft list tables validation w/ WARNING for bridge broute / bridge mangle /
  inet tune. Would have surfaced this regression in upgrade.log instead of
  post-deploy smoke.
- Write /tmp/.trixie-reboot-required flag when running kernel != 6.12.x
  (mirrors bookworm reboot-required pattern).
- Auto-reboot via 'shutdown -r +1' when reboot-required. UI-driven upgrades
  have no admin watching, so without this the box sits on the old kernel
  indefinitely. SSH users get a wall broadcast and can 'shutdown -c' to
  cancel. Same change applied to bookworm post_upgrade_fixups() for
  consistency. Gated on kernel mismatch, so same-distro patch upgrades are
  unaffected.

is_trixie_upgrade():
- Self-healing detector: re-run fixups if nft binary or required tables
  (inet tune, bridge broute) are missing, even when the fixup-done flag
  exists. Mirrors the bookworm detector.

protect_untangle_packages_from_autoremove():
- Add nftables to runtime_tools anti-sweep list as defense-in-depth.

(cherry picked from commit c5b24bc702d23442ea5edf04ed3c4ac32ec87271)

Subject: [PATCH 21/37] NGFW-15749: ATS test hardening for trixie post-upgrade
 flakes

Five tests failed on the 2026-05-28 bookworm->trixie ATS run that pass
cleanly on re-run minutes later. Root cause for 3 of them is the same:
Apache mod_python's DbmSession DB takes several seconds to warm up after
untangle-vm restart, during which login appears to succeed (Set-Cookie
returned) but the cookie isn't persisted server-side, so authenticated
admin paths return empty bodies or the apache "Permission denied"
fallback page.

test_administration.py (admin cert uploads):
  Consolidate the 4 duplicated login+multipart-upload blocks (~85 lines)
  into a single _login_and_upload_cert() helper that retries on empty
  response.text. Net 49-line reduction. Fixes test_021/022/023/025_invalid.

test_branding_manager.py (login page branding):
  Add _fetch_uvm_root_with_retry() helper -- GETs / via remote wget and
  retries until response title is not the apache fallback "Server" page.
  Fixes test_020_check_login_page_branding + test_021_changeBranding_*.

test_web_filter.py:
  - test_202/test_205: replace assertEquals (removed in Python 3.13) with
    assertEqual; 15 occurrences scrubbed.
  - test_205 concurrency assertion relaxed: which of 3 concurrent
    setBlockedUrls workers wins is implementation-defined; settings-file
    mtime is not a reliable proxy for winning-rule ownership. Accept any
    of the 3 worker IDs' rules being the survivor instead of pinning to
    the one whose settings file happened to be written last.

test_intrusion_prevention.py (test_300_flow_established_toggle):
  Tighten the leftover-detection grep from "flow:.*established" (greedy
  across `;` boundaries) to "flow:[^;]*\\bestablished\\b" (scoped to the
  flow: option value, word-boundary excludes not_established naturally).
  The old regex falsely caught any rule whose msg/content mentioned
  "established" after a correctly-stripped flow: clause -- a new
  Emerging Threats signature surfaced this on the trixie run. Source
  remove_flow_established() in suricata_signature.py is correct as-is.

test_directory_connector.py (test_060_user_authentication_adlm):
  Docstring-only clarification. Cross-checked against bullseye .172,
  trixie .138, and a third ATS .134: three different failure modes
  (AD audit on/off, ADLM agent forwarding on/off) prove this is AD test
  infrastructure flakiness, not an NGFW regression. No behavior change.

On trixie, UVM returns HTTP 302 for unauthenticated requests via
"localhost" but 200 via "127.0.0.1". This broke IPS signature updates
(intrusion-prevention-get-updates) and the serial console text UI
(ut-textui.py), both of which used hostname="localhost".

Subject: [PATCH 23/37] NGFW-15802: fix uvm_login.py IPv6 socket lookup for
 localhost auth
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

curl 8.x (shipped with trixie) resolves localhost to ::1 (IPv6)
internally, bypassing the system resolver. When Apache receives an
IPv6 loopback connection, uvm_login.py accepted ::1 as local but
then searched /proc/net/tcp (IPv4 only) for the socket — never
finding it in /proc/net/tcp6 where IPv6 sockets live. This caused
all localhost connections via ::1 to get HTTP 302 instead of 200.

Fix: when remote_ip is ::1, search /proc/net/tcp6 with the proper
32-char IPv6 hex address. IPv4 path unchanged.

Subject: [PATCH 24/37] NGFW-15749: fix test_310_system_logs unzip prompt on
 trixie

Trixie's unzip prompts for overwrite confirmation unlike bullseye.
Clean stale /tmp/system_logs before extracting, add -o flag to
force overwrite, and fix missing .zip extension in unzip command.

 on trixie

Trixie mod_python session handling can return non-JSON from /auth/login
during warmup. Catch JSONDecodeError and retry instead of crashing.

Subject: [PATCH 26/37] NGFW-15802: ATS Test fixes on trixie 1.reject invalid
 suricata variable names in IPS settings sync
 synchronizeSettingsWithVariables() splits get-config output on '=' and
 blindly adds any new variable to settings. If suricata.yaml contains
 corrupted entries (e.g. Python source leaked as a port variable), they
 persist across restarts. Only accept uppercase variable names matching
 suricata's convention (HOME_NET, HTTP_PORTS, etc.).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

2: tolerate kept-back packages on trixie steady-state updates

After trixie upgrade completes, is_trixie_upgrade() returns False but
regular updates with changed dependencies still produce kept-back
packages. Previously this caused ut-upgrade.py to abort, blocking
feature updates on trixie systems. Now tolerate kept-back on any
trixie kernel (6.12.x) since dist-upgrade resolves them correctly.

3: guard both directions of IPS variable sync + self-heal

create-config.py now skips invalid variable names when writing to
suricata.yaml (blocks settings→yaml corruption). Java sync also
purges existing invalid entries from settings on startup (self-heal
for boxes that already have the corruption from prior upgrades).

4: fix test_031_rule_modify empty rules list after test_030

test_030 deletes its rule at cleanup, leaving rules list empty.
test_031 assumes a rule exists at index 0. Add the rule if missing.

5: increase cert upload retry window for mod_python warmup

10 retries × 2s = 20s was insufficient on trixie ATS box where the
test suite starts shortly after UVM restart. Increase to 20 × 3s = 60s
to accommodate mod_python DbmSession initialization.

Subject: [PATCH 27/37] NGFW-15802: fix cert upload test failures on trixie ATS

Two issues caused test_021/022/023 to fail with 60s timeout in
full ATS runs on trixie:

1. admin.js not on disk: after bookworm->trixie upgrade, UVM holds
   admin settings in memory but writes admin.js to disk late in
   startup. The HTTP login handler (valid_login) reads from disk
   via settings_reader -- file missing means login always rejected.
   Fix: flush admin settings to disk via setSettings() JSONRPC if
   admin.js is absent before attempting HTTP login.

2. Double-slash URL: get_http_url() returns a trailing slash,
   producing //auth/login which Apache on trixie may not route to
   the mod_python auth handler. Fix: rstrip('/') on the URL.

Also requires python3-gdbm (added in prior commit to
untangle-apache2-config) to ensure mod_python's DbmSession uses
the gdbm backend instead of dbm.sqlite3 which lacks the
first()/next() API used by session cleanup.

Subject: [PATCH 28/37] NGFW-15826: remove admin.js flush workaround from cert
 upload tests

The flush workaround (get+setSettings to force admin.js/system.js to
disk) masked the real bug: ats-run.sh wiped settings while UVM was
still running after ut-upgrade.py restarted it. With the ATS runner
fixed to stop UVM before wiping, the workaround is unnecessary.

Subject: [PATCH 30/37] NGFW-15675: fix broken index.txt/serial.txt symlinks
 after root CA rotation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

NGFW-15675 changed symlinkRootCerts() to use Java file listing instead
of shell globs for the index*/serial* move (preventing shell injection).
However, it also symlinked index.txt and serial.txt to the timestamped
source directory. When removeCertificate("ROOT") later deletes that
directory, the symlinks break, causing ut-certgen to fail with exit 12
("Error generating signed certificate"). This silently breaks SSL
Inspector MITM cert generation — the app shows RUNNING but cannot
forge per-session certificates, so HTTPS traffic passes uninspected.

Fix: copy index.txt and serial.txt back as real files instead of
symlinking them. Unlike untangle.crt/untangle.key (read-only, safe
to symlink), these are OpenSSL CA database files actively written by
openssl-ca on every MITM cert generation and must always exist at the
top-level cert store path regardless of timestamped directory lifecycle.

Affected: both master and ngfw-release-17.5 (any box that triggers root
CA rotation after NGFW-15675 landed). Workaround for already-broken
boxes: ln -sf UntangleRootCA/index.txt index.txt (and serial.txt) in
/usr/share/untangle/settings/untangle-certificates/

Subject: [PATCH 33/37] NGFW-15675: move self-heal to constructor so it runs on
 every startup

The previous self-heal was inside symlinkRootCerts() which only runs
when untangle.crt/untangle.key are not symlinks. On boxes where the
root CA is already symlinked (normal state), symlinkRootCerts is
skipped and broken index.txt/serial.txt symlinks are never repaired.

Move the self-heal to the CertificateManagerImpl constructor so it
runs unconditionally on every UVM startup, after the symlink gate.

Subject: [PATCH 34/37] NGFW-15918: fix restart_uvm() NFQUEUE collision on
 trixie (JDK21)

JDK21 shutdown hooks take longer to release NFQUEUE sockets than JDK11.
Back-to-back init.d restart causes netcap init failure on the new instance.
Split into explicit stop, wait-for-java-dead (60s + kill -9 fallback), start.

Subject: [PATCH 35/37] Allow Pulse restart from DEAD state

Static singletons like WebrootDaemon create a Pulse once and reuse it
across app enable/disable cycles. When stop() is called, the Pulse
thread exits its run loop and sets state to DEAD. On the next start(),
the DEAD state was rejected with IllegalStateException, preventing
web-filter (and any app using WebrootDaemon) from ever restarting
without a full UVM restart.

This affects production customers who disable and re-enable web-filter,
and ATS runs where multiple test suites rapidly create/destroy apps
sharing the same WebrootDaemon singleton.

Allow start() from DEAD state alongside UNBORN and KILLED.

Subject: [PATCH 36/37] ATS: clean up apps when initial_extra_setup fails

When initial_extra_setup() throws (e.g. web-filter instantiation fails),
apps created during setup are left half-instantiated. Subsequent test
suites find them "already instantiated" and skip entirely, cascading
through the rest of the ATS run.

Call final_extra_tear_down() on failure to destroy leftover apps so
the next suite starts with a clean state.
