The EEE toggle posted `eee <port> <on|off>`, the reverse of the
`eee [on|off|status] [port] [100m|1g|2g5]` the parser and the
documentation describe, so the switch answered with its usage line and
the checkbox sprang back. The multi-page UI this replaced sent `eee on`
with no port at all, which toggled every port instead of one.
Moving the port to the end breaks the stored-configuration merge, which
builds its drop key as a line prefix: with the port trailing, a per-port
line matches the bare eee entry and replaces every eee line in the
configuration rather than the one for that port. Give the command its own
case beside the bandwidth one, so a line with a port replaces only that
port and a line without one clears them all, and accept the optional
speed word the command has always taken.
Reported by tofurky in issue #459.
The row sits between Hardware and Flash. The firmware sends the formatted string
rather than the raw register, since the System table prints its values as they
arrive.
Costs 186 bytes in BANK1.
The replay takes a line of at most 126 bytes, so a longer one is skipped
on boot. Neither the upload path nor the editor looked at line length,
so the file the user saved was not the configuration the switch would
come up with.
Reject such a body in config_take(), before the sector is erased, which
the upload path already maps to 400. The editor points at the offending
line and its length, and measures it in bytes rather than characters, so
a name written in a non-ASCII script is counted the way the switch
counts it.
Adds a numeric input next to the syslog settings to read and set the
session timeout without knowing the command. The current value is
reported in information.json, so the field also shows the default the
firmware was built with.
Costs 86 bytes of code (BANK1) and nothing in RAM.
Save to flash ran the stored config through the same filter as the
command log, so stored lines the page does not know were dropped. The
stored lines are now carried over as they are and only the log is
filtered.
ingress only changes the ports it lists, but the merge replaced every
stored ingress line. It now merges per port; "ingress t|u|a" still
replaces everything, and per-port settings an all-ports line already
overrode are not revived.
Write from the config editor no longer clears the command log or the
unsaved marker, since the edited text does not hold the changes made on
other pages; only Save, which merges them, clears the log.
The command log grows from 1 kB to 2 kB, which still fits the 2500 byte
output buffer, and send_cmd_log() stops at the end of that buffer.
The session timeout was a compile-time constant (200 s), so changing it
meant rebuilding the firmware. Make it a variable that keeps the same
default and add a "session <seconds>" command, so it can be set from
the console or from the startup configuration like the other settings.
Measured on KP_9000_9XHML_X_V3_1: ROM +180 bytes (BANK1 +17, BANK2
+161) and xdata +2 bytes; the internal RAM map is unchanged.
The firmware counts every authenticated request as session activity, and
the page polls the status every 2.5 s, so an open tab never let the
session expire. Track the last mouse, key, touch or wheel event and treat
the page as hidden once ten minutes have passed without one: the pollers
keep ticking but send nothing, the session times out in the firmware as
it did before, and the next input resumes polling, which meets the 401
and returns to the login page.
The firmware lists a LAG as its own entity in /stp.json (`lag` and `mbr`,
`p` 0) and drops the member ports from the list; its settings take
`stp lag <n>`. Give the group its own row in both spanning tree tables,
named with its members, key the cells by entity rather than port number,
and rebuild the tables whenever the entity set or a membership changes so
a group created on the LAG tab appears without a reload. The `stp lag`
commands are recognised for the unsaved-changes badge and the startup
config merge alongside `stp port`.
A dark receiver reports 0 mW, which printed as -Infinity dBm. The DOM
value has a resolution of 0.1 uW, so -40 dBm is the lowest reading the
module can express; clamp there.
The header carried the save button, the language selector and the theme
selector on every section, although the latter two are set once. They
now live in a Display card in the System section; the header keeps the
title, the unsaved-changes badge and Save to flash.
The forwarding database is read a page at a time; leaving the MAC table
or ports section let the walk carry on through the request queue. Give
the walk a generation number that the leave hooks bump, and stop the
walk at the next page when it is stale.
The VLAN table is one /vlanlist plus one /vlan.json per VLAN. A failed
per-VLAN request rejected the chain, so every VLAN after it was missing
from the table, indistinguishable from VLANs that do not exist. Keep the
row with the id and name from the list and a ? in the port columns.
Save to flash showed the merged startup config read-only, so a stray line
had to be fixed afterwards in the System section. The preview is now a
textarea: the size and unknown-line notes follow the edits, the write
button is disabled above 2048 bytes, and what is written is the edited
text.
The default hostname (RTLPlayground- plus six hex digits) overflows the
200 px sidebar; clip it with an ellipsis and keep the full name in the
title. The MTU and Mbit/s fields were 70 px, which leaves no room for five
digits next to a number spinner. The main column stops at 1400 px instead
of 1100 px so the dashboard cards sit side by side on a wide screen.
The old dashboard showed a hover tooltip per port with the link state and,
for SFP ports, the module and its DOM readings, and rewrote it on every
poll. The single-page app replaced it with a click-to-open dialog that was
a snapshot: the values did not change while it was open.
Build the rows once per port and use them for both: the dialog is
re-rendered on every status poll while it is open, and each port in the
strip carries the same rows as its title.
The firmware emits every per-port array in logical port order, which on a
board with a remapped port table (SWGT024: phys_to_log = {4,5,6,7,8,3,...})
is 6, 1, 2, 3, 4, 5. The old pages iterated over physical port numbers and
looked each entry up; the single-page app rendered the arrays as received,
so the ports, spanning tree, EEE and bandwidth tables and the dashboard
strip came out in logical order, and the strip put the SFP marker and the
detail view on the wrong port.
Sort every array by portNum on receipt so index i is port i+1 throughout.
The pages become one index.html holding every section, one app.js and a
self-contained login.html. The layout is a sidebar with light, dark and
Selenized themes (or follow the OS), a live dashboard with per-port
packet rates, and confirmation dialogs in front of the actions that can
lock the operator out.
Behaviour changes against the previous pages:
- every request goes through one queue that waits for the previous
response BODY rather than its headers: the firmware shares a single
output buffer across connections and delimits responses by closing,
so a second request in flight corrupts the first
- "Save to flash" merges the command log into the startup configuration
with the grammar the console accepts, shows the result before writing,
verifies the sector by reading it back and clears the command log only
after that; the header shows an "unsaved changes" badge while the
running configuration differs from flash
- the console section shows the output the firmware returns for a
command, including the parser's explanation on a rejected one
- the firmware update section checks size, bank header and CRC16 of the
image in the browser before uploading, shows upload progress and waits
for the switch to come back after the reset
- the ports table shows the learned MAC of a port when there is exactly
one and the count otherwise; the MAC table sorts per column, filters,
and names the LAG a learned address sits behind
- the spanning tree section sends only the settings that changed on
Apply instead of one command per control event
- link aggregation groups are numbered 1-4 like the command line, and
applying an empty group clears it
The translation table is inline in app.js with English, Japanese and
Chinese. The language selector sits in the page header and reloads the
page so that dynamically built tables are rebuilt in the new language.
Only login.html and the favicon are served before authentication; the
stylesheet, the port images and the old script bundle no longer exist.
The simulator's allowlist follows the firmware's.
The web UI became one index.html plus one main.js while this branch was
open, so the STP page changes had no html/stp.js and html/config.js left to
live in. They are re-applied here against the new structure.
A row now carries two derived fields: the name the CLI expects for it
("port N" or "lag N") and the key its controls are keyed by (the port
number or "LN"). A group's row is labelled with its front panel members,
which /stp.json reports in the mbr field.
conf_cmds and conf_overwrite accept the "stp lag N ..." forms so the
startup config keeps them.
Leaving SFP ports out of the table is deliberate for now, and being able to
force a module's speed belongs in a feature of its own rather than arriving
inside a fix, so that half goes again.
What remains is the off-by-one: createPortTable() read pState[i] where the
array is filled by portNum - 1, so every row started out showing the next
port's link speed until the first refresh corrected it. The debug line above
it goes too; it printed a third index, pState[i-2].
The port table skipped every SFP port outright, so on a SWTGW218AS the
uplink simply was not there. Of the seven columns only Set Speed is
meaningless for a module: the name, the link speed and the devices behind
the port all are worth showing, and the name in particular was accepted on
another page and then never displayed anywhere. The MTU table further down
the same page has always drawn the port, so the page disagreed with itself.
Give an SFP port its row and leave the three control cells empty. Whether
speed and disable should work for a module is a separate question and
untested, so this does not offer a button for it.
The link state was read one port too far. main.js fills pState by
portNum - 1, updatePortTable() reads pState[i-1], and createPortTable()
read pState[i], so every row started out showing the next port's link
speed until the first refresh corrected it. On the last copper port that
meant showing the uplink's speed. Feeding the real status.json of a nine
port switch through both versions:
expected 7 7 7 1 7 1 7 7 6
before 7 7 1 7 1 7 7 6
after 7 7 7 1 7 1 7 7 6
Dropping the skip also removes a trap rather than papering over it.
updatePortTable() addresses rows as tbl.rows[i], which only lined up with
port i because the SFP port happens to be last on this board. With a
module in the middle every row after it would have been off by one.
A device on an aggregate is learned against whichever member the frame came in
on, and the hash moves that around: the same address changes port every time
the flow mix changes. The table was telling the truth and there was no way to
read it, since nothing on the page or the console says those two ports are one
link.
port_lag_of() already exists and already knows the answer, so both views ask
it. The console prints LAG1 in place of the member, and /l2.json carries a
"lag" field beside the port, 0 when the port stands alone, which is the shape
/stp.json already uses.
Costs 151 bytes of BANK1.
The LAG page draws four sections headed LAG 1 to LAG 4 and wires their buttons
to lagSub(0) through lagSub(3), which then sends the index straight through as
the group number. So the first button asks for "lag 0", which the parser
rejects, and the page shows nothing at all because the error only goes to the
console. Every other button is off by one: the section headed LAG 2 creates
group 1.
The index stays 0-based for the element ids and only the command gets the
1-based number the CLI documents.
The firmware now refuses to delete the switch's own entry, so the
button on the CPU row can only fail; leave it out. When a delete
succeeds, remove the entry from the cached table and repaint instead
of leaving the stale row until the next refresh.
fetch() does not throw on 4xx, so a request that came back 401 after the
session had timed out reached the same line as a successful one: the
window showed the prompt and nothing under it, and the input was cleared
as if the command had run. The session lasts 200 seconds, so leaving the
tab open is enough to hit it.
A 401 now goes to the login page instead. The transcript also gets a
trailing newline when the answer lacks one, so the next prompt does not
run into the last line of output, and it is capped so a long session
does not keep growing the node.
The console tab posts to /cmd and throws the response away, so the page stayed
silent whether the command worked, was refused or was just misspelt. Now that
/cmd answers with the command's output, the page keeps a running transcript:
each command echoed after a prompt, then whatever it printed.
The box is a pre element filled through textContent, so nothing the device
prints is taken for markup. It scrolls to the newest line and the input clears
after a send.
Saving the configuration drops the syslog server address whenever the log
of executed commands also contains "syslog on", which it almost always
does, since you have to enable the thing after pointing it somewhere.
parseConf() deduplicates by taking the matched text of a conf_overwrite
entry and removing every stored line that starts with it. For "syslog on"
the entry that matches is the catch-all ^syslog\b, so the matched text is
just "syslog" and the filter removes anything beginning with "syslog ",
including the "syslog ip ..." line saved a moment earlier. The address then
falls back to 0.0.0.0 on the next boot.
It fails quietly: nothing is reported, the running switch keeps logging
until it is restarted, and the loss looks like the firmware forgetting a
setting rather than the page dropping it.
Narrow the entry to the commands it is meant to collapse, so the address and
the port keep their own entries and are no longer collateral.
That alone would stop "syslog on" and "syslog off" from replacing each other,
because the list drops lines starting with the text it matched and "syslog off"
does not start with "syslog on". A separate list names the stem of such a pair
and collapses the two, which is what the catch-all used to do by accident.
The port was frozen at 514 in the call that opens the connection, so a
collector listening anywhere else was simply out of reach, and plenty do,
because 514 is privileged and containerised collectors usually get a high
port instead. Working around it meant putting a proxy in front, which then
rewrites the source address and hides which device actually sent the line.
Add `syslog port <n>`. The default stays 514, so nothing changes for an
existing configuration. Setting it tears the connection down and builds a
new one, the same dance the address already does, because uip_udp_new()
freezes the port into the connection.
The value is parsed here rather than through atoi_short(), which reports
"no digits" but not overflow: 65540 would quietly wrap to 4 and we would
open a connection to a port nobody asked for. Checking before each multiply
keeps it in 16-bit arithmetic. Zero then covers all three ways to be wrong -
no digits, past 65535, or an explicit "0", which is not a port either.
Whitelist the new command in config.js as well, next to `syslog ip`, or the
line is dropped without a word when the configuration is saved and the
setting quietly fails to survive a reboot. The dedup entry has to precede
the general `^syslog\b` one, otherwise it would deduplicate against
`syslog on`.
itoa_short() is new: itoa() only handles a byte and print_short() prints
hex, so there was no way to show a port as a decimal number. Kept separate
from itoa() rather than widening it, because every existing caller passes a
byte and would start paying for 16-bit divisions it does not need.
The scratch variables for the parser live in xdata. Locals there would take
internal RAM, and this image has none left: data ends at 0x77, the overlay
occupies 0x78-0x7f and the stack starts at 0x80. Measured: no module's DSEG
grew.
cmd_parser.c conflicted twice: main rewrote the pvid command around the
new port-separator and atoi helpers, next to the line where this branch
delegates "stp" to stp_parse(). Both belong, so the STP delegation keeps
main's pvid body.
The linker caught what the merge could not see: main changed atoi_byte()
to return the digit count and leave the value in atoi_results_u8, where
it used to return non-zero on failure and write through a pointer. Note
the sense is inverted, so the three calls in rtl837x_stp.c are adjusted
rather than just re-arranged.
The window could be armed from the serial console but only ever disarmed
by an HTTP request. save_cmd, which gates arming, is cleared only while
execute_config() replays the startup config, so every interactive command
armed it wherever it was typed, while mgmt_alive, which disarms it, was
written in exactly one place, on HTTP traffic. An operator working
entirely on the serial console therefore lost STP 180 seconds after
enabling it however much they typed, which is what makes the mechanism
impossible to test from a console.
The documentation described the behaviour that was intended rather than
the one that was built, and in both directions: it said a command on the
serial console also confirms, and it said a reboot with STP in the
startup config disables it again three minutes later. Neither held. The
replay path never armed the window at all.
Repairing the asymmetry would have kept a mechanism whose premise is
contested anyway. A watchdog that switches the protection off in response
to silence adds a second failure mode on top of the first: where the
network is misconfigured and STP is the thing holding a storm back,
restoring forwarding removes the last reason management still answers.
Gone with it: the stp failsafe command, the fs and fsT fields of
/stp.json, the input and the tripped banner on the Spanning Tree page,
the two persistence patterns in config.js, the documentation section, and
mgmt_alive itself, which had no other reader.
550 bytes back, 145 of BANK1 and 405 of BANK2, and five of xdata, which
is the four counters and mgmt_alive and nothing else. Built for
SWTGW218AS and KP_9000_6XHML_X2 on sdcc 4.5.0.
Three things from the page feedback.
The rows came out in logical order while carrying the physical port number,
so on the six-port boards the first row is labelled 5. Sorting the rows by
that number in JS puts every board back into front-panel order. I walked all
25 machine definitions and each one now yields a clean 1..N.
The Designated Bridge column is hard to read without knowing this switch's
own bridge ID, so the status line shows it in the same priority and MAC shape
as the cells use. On the test switch that reads 61440-06:05:16:1E:F9:24 and
matches the Designated Bridge of every locally designated port, which is the
comparison that was missing. The root bridge and the path cost now use the
same formatting as the columns instead of raw hex.
Enabling STP printed nothing until the next poll, and because the ports start
blocked, management can stay quiet for the whole listening and learning
period, so the page had no chance to say anything later. It now writes what
is about to happen before the command goes out, and how long the ports need.
Page data only. Both banks, xdata and the common bank are unchanged.
Bring the Spanning Tree page in line with a typical managed switch's
per-port panel. Configuration gains the full-range path cost (raw
0..200000000, 0 = auto, replacing the old 1000x-scaled byte), a
point-to-point admin control (auto/on/off), and the priority is now a
0..240 step-16 dropdown. A new status table shows, per port, the Port
State, Role, Designated Bridge / Port ID / Cost (learned from received
BPDUs, kept per port and aged via the BPDU age), Operational Edge and
Operational Point-to-Point.
The designated fields fall back to presenting this switch as the
segment's designated bridge when no fresh BPDU has been heard (so a
quiet port shows our own bridge-id, as the vendor UIs do). /stp.json
carries the packed hex fields plus our own MAC for that fallback.
Space: reclaim BANK2 for the above by moving rtl837x_pins to HOME and
compacting leds_dump into a register-address table (~800B); bandwidth
returns to BANK1. No BANK3 - hardware-verified that PSBANK > 2 crashes
this SoC at boot (a bricked unit and an SPI-programmer recovery earlier
today); a warning to that effect is now in rtl837x_lldp.c.
Hardware-verified: cost 200000000 and p2p off round-trip through the CLI
and JSON, the status table populates correctly with STP enabled (all
ports Forwarding/Designated, oper-edge and oper-p2p True), LACP 3f/3f
and the LAN unaffected.
(cherry picked from commit 2ec62072f061dc9e78bc821ba1c297cb6819e206)
Enabling STP on a bridge whose management rides an in-band VLAN can cut
off that very management - and not only by our own blocking: on this
network the upstream TP-Link Easy Smart switch's "loop prevention"
reacted to our BPDU hellos by blocking ITS port towards us while our
ASIC was all-forwarding, isolating the whole segment until a power
cycle. Recoverable only by going quiet.
Add a commit-confirm watchdog: while STP is enabled, any HTTP request
re-arms a countdown ("stp failsafe <seconds>", default 180, 0 disables);
if management stays silent for the whole window, STP disables itself,
which also stops BPDU TX so a neighbour's loop protection can release
its block. The web UI polls /stp.json every 2 s, so an open browser
naturally keeps the watchdog re-armed. The trip is reported via
/stp.json (fs, fsT) and as a warning on the Spanning Tree page.
Deliberately not conditioned on our own MSTP port states - the incident
above proves the uplink can be dead while every local port forwards.
Also bound the NIC DMA busy-waits (nic_tx_packet, nic_rx_header,
nic_rx_packet): an unbounded spin on SFR_NIC_CTRL freezes the entire
main loop (timers, HTTP, ARP) if the ASIC ever fails to consume a
transfer; give up after ~65k polls and drop the frame instead.
Hardware-verified end to end: with priority 15 against a live RSTP
bridge the uplink died 6 s after "stp on" and the network recovered BY
ITSELF 66 s later (trip at 45 s + neighbour release), fsT=1, LACP and
LAN intact. Telemetry via syslog-to-edge-port host confirmed the full
chain: countdown 44->4, trip, hello TX stopping at the trip.
(cherry picked from commit 1fa9775156fd6d7ebfdda2382f73430b86601230)
Implements the standard 802.1D-2004/802.1w configuration surface:
Bridge: priority (0-15 x4096), hello time, max age, forward delay,
force-version (RSTP v2 / STP-compatible v0 Config BPDUs), tx hold
count (per-port per-second BPDU budget).
Per port: enable, admin edge (forwarding immediately - no listen gap),
auto edge (forwarding after 3 s of BPDU silence; DEFAULT, so
host-facing ports no longer take the full forward delay),
path cost (0=auto/20000), port priority, BPDU guard (port disabled
on BPDU receipt), root guard (never accept a better root on the
port), BPDU filter (no BPDUs in or out).
Engine additions: root max-age expiry (reclaim the tree when the root goes
silent), root path cost accounting (rx cost + root-port cost, advertised in
our BPDUs), loop detection (our own BPDU coming back blocks the port for a
listen period), topology-change counter, approximated per-port roles
(Root/Designated/Alternate) for diagnostics.
CLI: "stp prio|hello|maxage|fwd|txhold|version ..." and
"stp port <n> on|off|edge|cost|prio|guard|filter ..." (stp_parse, delegated
from cmd_parser); all forms accepted by the startup-config validator so the
whole configuration persists. /stp.json now reports config + status; the
Spanning Tree page exposes everything with immediate-apply controls and live
state/role columns (edit-in-flight guard against the 2 s refresh).
8051 memory: the module moves to code BANK2; internal-RAM pressure from
cross-bank calls resolved by xdata loop iterators/scratch, __reentrant on
the small helpers, and moving httpd's header-pointer globals to xdata.
Verified on hardware (SWTGW218AS): defaults land per standard; priority and
hello change live; admin-edge ports (the LACP bond uplinks) keep the LAN at
0% loss THROUGH "stp on"; auto-edge ports forward after 3 s; a port that
heard real BPDUs (a VM bridge behind physical port 6) correctly declined
auto-edge, sat out the full listen period and became Designated; tc counts
promotions; we win the root election at priority 16384 vs 32768.
(cherry picked from commit 09a34dc6acdc81ab9cab0727d2f4a59c68131a3e)
Add a Spanning Tree page: an on/off toggle driving the existing "stp"
command over /cmd, and a live status section fed by a new /stp.json
endpoint - the elected root bridge (priority + MAC), our path cost,
whether we are the root, and the per-port STP state read live from the
ASIC's MSTP register (same 2-bit encoding stp_setup() writes). Ports are
reported by their physical numbers.

Adds a Connected devices column to the Port Configuration table, fed by
the shared walkL2() helper. A port with a single MAC behind it shows the
MAC directly; several are shown as a count with the full list in the
cell tooltip, since picking one of many to display would suggest it was
"the" device. The walk restarts 15 seconds after each completion and
starts 3 seconds after page load to stay clear of the initial status and
MTU requests. A walk that ends without ok keeps the previous cells,
since an incomplete table would blank ports that have devices behind
them. Translations for the three languages included.
Resolve the conflicts against the 41 upstream commits since 52692d0:
- Makefile: keep the upstream parallel-build fixes (grouped html_data
target with order-only deps, create_build_dir, crtbank, deterministic
BUILD_DATE, atomic version.h write) and keep the minify + gzip
pipeline (-z, html_min, .css/.ico in the html file list) on top.
- html: l2.js stays removed; port the upstream L2 fixes into the
single-page main.js (walkL2() with empty-reply and 4096-entry cap
handling, 3 retries on error). The L2 poll now re-schedules itself
after each walk and stops when the section is hidden.
- httpd/httpd.c merged cleanly (gzip Content-Encoding alongside the
upstream GET walk bound and counters.json port check).
- doc/webui-compression.md: describe the upstream version.h write.
Verified: KP_9000_6XHML_X2 and PCB_K0402WS_V3 build sequentially and
with make -j8; all 8 embedded files decompress byte-identically;
httpd_sim serves main.js/index.html and the L2 JSON endpoint.
