Moving the global on/off onto the LLDP page
Building a table of LLDP status from the S ports. Later on, if
we wish to implement an lldp receiver we can display the remote
details here
Adding support to the cmd parser for the lldp commands
A matrix of the ports, one row per ingress port, showing which ports a
frame entering there may leave through. The port number of a row turns
red when the port is not fully open, and the cell for the port itself is
marked since it is always allowed. Apply sends one "isolate" command per
changed row, and Allow all ticks the whole matrix.
The switch side is a new /isolation.json, which reports each port's
allowance mask read back from the hardware. The page is an Isolation
section of the single-page UI.
Building with SDCC 4.6.0 emits tons of warnings e.g.:
cmd_parser.c:31: warning 356: object in read-only code space should be const
cmd_parser.c:36: warning 357: pointer to object in read-only code space should be pointer to const
These of course become fatal when building with --Werror.
Comparing resultant binaries, it seems that a single string is shifted
(deduplication?) but the numbers emitted at the end of the build are
otherwise identical.
The session cookie carried neither Expires nor Max-Age, so browsers that
clean up session cookies aggressively (LibreWolf, for one) may drop it
while the session is still valid. Send Max-Age=session_timeout so the
declared lifetime matches the timeout already enforced by the firmware.
itoa16_html() only converted four digits, so extend it to five to print
timeouts up to 65535. That also fixes information.json, which used the
same helper and reported wrong values from 10000 s up.
The /cmd path carried its own copy of the plain-text response header,
which was the same string page_impl.c already keeps in
HTTP_RESPONCE_TXT, minus one difference: the shared one never said
Connection: close.
This httpd closes after every response, so a reply that does not
advertise it invites the browser to reuse the socket and lose the next
request. HTTP_RESPONCE_JSON has always said so; the text one was the
odd one out, and send_config() and send_cmd_log() were answering
without it.
The copy is gone and the shared string carries the header. The check
for a command that printed nothing now compares against the length
strtox() returned instead of sizeof() on the macro.
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.
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.
Recovered-from: 3132319, 9365c86
Returns a JSON array of all configured VLANs with their IDs and names,
e.g. [{"id":1,"name":""},{"id":20,"name":"IoT"}].
The endpoint iterates VLAN IDs 1..4094 and filters by the validity bit
in sfr_data[0] (0x02), following the same pattern as vlan_create() and
vlan_setup() in rtl837x_port.c.
Also adds a small itoa16_html() helper for emitting decimal numbers
up to 4 digits (analogous to the existing 8-bit itoa_html()), used
for VLAN IDs which can reach 4094. Response builder uses the existing
vlan_name() helper for the name lookup, consistent with send_vlan().
Buffer overflow is prevented by breaking out of the iteration loop at
TCP_OUTBUF_SIZE - 60.
This endpoint is the foundation for upcoming UI improvements
(VLAN selector dropdown and overview table).
flash_read_bulk() is kind of a printf function. But did not work as well.
flash_read_bulk() was used in the http generation so this needed to be changed as well.
For the website we decided that we are going to use CSR(Client Side Rendering).
So every HTML and JS files are now static.
Variables are fetched via json calls and output is render on the client side.
Also usefull for the future when we want a REST like API.
execute_config() was also using flash_read_bulk().
This have been replaced with flash_read_bulk() and parsing the flash_buf buffer.
