Reaper v3.3.4-beta — RT-BE86U

v3.3.4 — a real Site Survey, destination names in the Flow Explorer, Policy Routing rebuilds without a gap, the ZenWiFi BQ16 Pro joins

• A real Site Survey replaces the stock one (field, RT-BE86U: "nothing beyond channel 44"). The
  stock Network Tools page ran a prebuilt scan core whose fixed event buffer kept only the first
  networks in channel order. Reaper_Survey.asp reads wl escanresults per radio through a
  detached worker (httpd/reaper_survey.c, a libc parser; 512-network cap; never runs beside a
  capture or Auto Scan) and shows each radio's own outcome - networks and time, a passive or
  own-block fallback, radio off, or the driver's own error text and exit code. Channel occupancy is
  drawn as one card per channel with this router's channel marked. A 5 GHz radio under radar
  monitoring refuses every scan request on this platform; a plain Scan never moves a radio and says
  so. Scan with channel move (two-step confirm) does what the stock core did silently: it moves a
  5 GHz radio that heard nothing to 36/80 or 149/80 with the chanspec and acs_update iovars - a
  bare wl chanspec changes only the configured value of a running radio - scans once the radio
  really operates there, and returns through dfs_ap_move when the driver has background radar
  checks, so the radio keeps serving through the minute-long check. A move cut short is undone at the
  next start. The worker resets SIGCHLD: it inherited httpd's reaper, and every exit status had read
  -1.
• The Flow Explorer names the destination. rdnsmapd learns names at DNS time instead of looking
  anything up: an AF_PACKET socket with a 16-instruction classic BPF filter (UDP replies from port
  53) blocks in recv, and every A record in a reply's answer section is stored under the question's
  name, which follows the CNAME chain for free. The table is a 131,136-byte tmpfs file that the daemon
  and httpd both map (shared/reaper_dnsmap.h: 2048 slots, earliest-expiry replacement, TTL clamped
  to 1-24 h), so there is no publish or parse step and no idle CPU. A Names switch on the page
  (default on) stops the daemon and deletes the table; switching it back on sends one reverse query
  per listed remote address to the local resolver (about 50 per second, capped at 512) and shows those
  names muted until a forward reply replaces them. The page keeps a name while its address is listed,
  labels the router's own bridge addresses "This router", treats every live bridge subnet as LAN (not
  only br0 - guest and VLAN sources showed the WAN address), and its detail panel now follows the
  reader down the list.
• Policy Routing rebuilds without a rules-free window. An Apply used to tear the chain down and
  build it again. rc/reaper_pbr.c now builds the new rules under a second chain name, replaces the
  PREROUTING jump in place (-R), drops the old chain and renames the new one; routing rules are
  kept or added first and only stale ones are deleted afterwards. A full teardown happens only when
  the feature is switched off.
• The DNS health check holds its verdict while the uplink is down (owner RT-BE96U). Each WAN blip
  cost a resolver failover, a re-apply, a restore and two extra dnsmasq reloads, because a
  LAN-side resolver failed the real-query probe whenever the uplink was gone. rc/rdnshc.c no longer
  counts a miss while the WAN is known down; boxes without the WAN state keys are never held.
• A clock that is already right counts as synced (field, RT-BE86U). busybox ntpd slews a clock
  that is within a second, and amtm's RouterDate pre-sets it, so the sync hook - which honoured only
  step - never set ntp_ready, and WireGuard, OpenVPN, cron and add-ons waited 23 minutes or more.
  A stratum or periodic event with a valid stratum now counts as the first sync.
• The firewall chains are signed and watched. apply.sh writes an md5 of each Reaper filter chain
  and the nat chain; rwatch recomputes it, and two ticks of drift re-apply the committed rules under
  the firewall lock (600 s apart, at most twice, never while a change is armed). rwatch's incident
  bundle now takes the kernel log and a 300-line syslog tail first, before its own accelerator dumps
  push the trigger out, and the syslog mirror rotates before appending, not after.
• rpunctd no longer resets on one odd read. A single differing chanspec read was taken as a
  channel change (six false resets on wl1 in two days, each discarding the puncturing baseline); a
  second read must now agree.
• Diagnostics v1.3.29. Reads a boot that rotated into syslog.log-1; adds findings for an unset
  ntp_ready after 300 s, for every probe lost and for a log that starts after the boot; prints the
  lease time remaining (udhcpc stores boot uptime plus lease); labels mounts hidden by a later mount;
  lists each log file once when /tmp names are symlinks to /jffs; adds the name map's counters.
• Image and build hygiene. A stock Makefile line copied the toolchain's own x86-64 libexpat.so
  into /lib of every image (197 KB no ARM process could load); it is gone, and reaper_verify
  gained a host-arch check that fails on any non-ARM binary in the staged filesystem. Quagga
  (zebra, ripd) is no longer built: it shipped inert, with a default vty password.
• Interface. DTIM Interval defaults to 1 on every radio, set once per box, with the explainer
  saying why; the Wireless Settings scheduler grid opens over the row you clicked; the firmware
  overlay shows no button during a download and the upload veil lost its dead Cancel; the System Log
  dropdowns explain themselves; the About page's vendor credits are reworded; 94 strings that were
  still English in every language pack are translated (19 brand and acronym tokens stay).
• The ZenWiFi BQ16 Pro joins (BE30000, quad-band 2.4/5/6/6 GHz). Same GPL drop as the BQ16, the
  GT-BE98 Pro's radio layout, its own radio driver and dongle firmware from the stock Pro image. It
  builds and passes verification and publishes as a prerelease; it carries the BQ16's header art
  until its own is drawn. No tester has run it yet.
• Tooling. New host suites test_site_survey.py and test_dnsmap.py (the DNS parser, the BPF
  program run through an interpreter, the backfill), test_pbr_apply_script.py drives the swap-in
  against a stateful fake iptables, and test_reaper_diag_counters.py covers the rotated boot. The
  stale-configure guard (build-scripts/reaper_stale_configure.sh) now also clears a package's
  stamp-h1: 76 packages in the router Makefile re-run configure only when that sentinel is missing, so
  clearing the Makefile alone left the package unbuildable (hit by this rung's cut build on expat).

Images & checksums (RT-BE86U)

Two flashable images: + AI Advisor (default) and Standard (noMCP, all AI components compiled out entirely). Flash the *_nand_squashfs.pkgtb via Administration > Firmware Upgrade.

This is a beta release. Its filename carries _BETA and the router reports the same string on the dashboard and the About page, so you can always tell which channel a flashed image came from. Stable releases carry no marker.
