494320b removed strcpy() from rtl837x_flash.c but left its declaration
in rtl837x_common.h. Since then the linker has taken strcpy from the
SDCC library instead, which expects the destination as a generic pointer
in DPL, DPH and B. The callers pass an __xdata pointer and leave B as it
is, so the copy lands wherever B happens to point. boot.c only gets away
with it because B is zero there; a call with B set, as from the ChaCha20
test in #207, writes into internal RAM and stops the 8051.
With several switches open, every tab was called "Switch". The
dashboard tab now shows the hostname, and the login page shows the
hostname seen at the last login on that address (kept in localStorage,
which is per switch), or the address itself before the first login.

The firmware page accepted any valid image, also one built for a
different board whose SFP, LED and button pins differ. Every image
carries its machine name as a NUL-terminated string, the same one the
switch reports as hw_ver; when the selected image lacks it, the page
now warns below the check result and in the confirmation dialog. The
upload stays possible on purpose.

The V3.2 board has the same component placement as V3.1 and works with
its machine definition: RJ45 links at 2.5G, LEDs, SFP detection with DOM
readings at 10G, factory MAC at 0x1FC000 and the reset button. The new
target only reports "V3.2" as the machine name.
Installed from the original firmware V100.9.25 through its web
interface with the OEM installer image. Reading the flash in-circuit with
a SOIC-8 clip gave the chip ID EF FF FF, as on a V3.1 board.

Follow-up to #494. Storm control (#455) was merged after it and brings
three objects in code space without const: the extern declaration of
machine in rtl837x_storm.c and the name tables storm_types and
storm_names. SDCC 4.6.0 reports them as warnings 356 and 357, which
fail the build with CI=1 (--Werror). SDCC 4.5, which the CI uses, does
not report them.
The declarations now take the form used in the rest of the tree, as in
mime_strings in httpd.c. The images for KP_9000_6XHML_X2 and
KP_9000_9XHML_X_V3_1 are byte-identical before and after.
Adds a German dictionary to LANG in app.js (all 317 keys, placeholders
unchanged), the language selector entry in index.html and the login
strings in login.html. Uses Swiss spelling (ss instead of ß), which
reads correctly for all German speakers.
Checked against a mock of the httpd endpoints: every section renders
with the German strings; no layout changes compared to English.

Only frames to 01:00:5e:00:00:16 reached the IGMP handler, so v1/v2
reports, which go to the group address, were never seen. The handler
also took the group from the first v3 group record for every type.
Pass all IPv4 multicast to the handler, which takes the IGMP header
from the IP header length, the group from the IGMP header for v1/v2
reports and v2 leaves and from the first group record for v3, and
returns 0 for anything that is not IGMP so it goes on to the IP stack.
The message and record types have names now.
Storm control used meters 0 to 39, the same meters the ACL hands out,
so a storm limit and an acl meter could overwrite each other. It now
uses 24 + port * 4 + type, meters 24 to 63.
parse_storm() is no longer reentrant and uses plain locals, looks the
type up in a while loop and returns straight from the one-line cases.
storm_show() uses plain locals too.
The documentation says how IGMP decides between mcast and umcast, how
to get from a meter index to its limit, where the IFG bit of a meter
is, and what an ingress bandwidth limit on the same port does to the
storm limit.
The switch has no battery backed clock, only a seconds counter that starts
at zero on every boot. An SNTP client keeps UTC as the time of the last
answer plus the seconds counted since: "ntp server <name|ip>", "ntp interval
<minutes>", "ntp timezone <+hh:mm>", "ntp dst off|eu|us", "ntp on|off",
"ntp" and "time". A server given by name goes through the DNS resolver, an
answer from an unsynchronised server is ignored, and a failed attempt is
repeated after 30 seconds.
The local time adds the time zone offset and, while the European or United
States rule says so, one hour. The date is split with a shift and subtract
division and a walk over the years, so no 32-bit division from the library
ends up in the common area.
The System page gets the NTP settings and shows the local time.
A small resolver for IPv4 address records, so that clients such as NTP can
be given a host name: "dns server <ip> [<ip>]", "dns lookup <name>" and
"dns". Without a configured server it uses the one DHCP handed out. A query
goes to the servers in turn every two seconds and gives up after six tries;
answers with compressed names and CNAME records ahead of the address are
understood. A name that already is a dotted address is taken without a
query.
The resolver sits in BANK3, the command line in BANK2 next to the helpers it
uses. The System page shows and sets the servers.
The image rule no longer passes -p, so fileadder fell through to printing
html_data.h and html_data.c on stdout on every image build. The listing is
only useful when fileadder is run without an image, to see what it would
generate.
The .bin rule passes -p html_data to fileadder, which rewrites
html_data.c and html_data.h after the objects that include them have
already been compiled and linked. The next make therefore rebuilds
html_data.c, httpd.c and page_impl.c even when nothing changed, and
so does the one after that. The rule only needs to embed the files
into the image; the header comes from the html_data.c rule above.
Spotted by plaes in #358, which cannot be merged as it stands.
With this and the previous commit, a second make after a full build
compiles nothing, and the image is byte for byte the same as before.
Two things kept the same source from producing the same image.
fileadder walked the input directory with readdir(), which returns entries
in whatever order the filesystem hands them over. The same tree therefore
embedded the files in a different order on a different filesystem, and the
image differed byte for byte. scandir() with alphasort() fixes the order.
version.h was listed in .PHONY, which makes it permanently out of date and
propagates that to everything including it, so a plain build recompiled the
four largest translation units even when nothing had changed. Dropping it
from .PHONY alone would go too far the other way: with no prerequisites the
recipe would never run again and the version string would freeze at its
first value. A FORCE prerequisite keeps the recipe running every time, and
the generated header is only moved into place when its content actually
differs, so the timestamp survives an unchanged rebuild.
Measured on this tree: with FORCE the version follows GIT_VERSION and an
unchanged rebuild leaves version.h untouched; without it the header keeps
the value from the first build.
Restore the sy_igmp and sy_services_note lines to their original
indentation so they do not show up as changed in the diff; the new
session timeout strings move to their own lines. Also add the es
strings, which were missing after the merge with main.
test_port_tables and test_page_json link httpd/page_impl.c unmodified,
which now references session_timeout. Define it in support.c next to
the other firmware globals so the tests link again on current main.
The server timeout is an inactivity timeout: scan_header() refreshes
last_session_use on every authenticated request. Max-Age counts from
login instead, and the cookie is only set there, so the browser deletes
it session_timeout seconds after logging in however busy the session
is. Leave expiry to the server, which already handles it.
The five-digit itoa16_html() stays: information.json must print
timeouts from 10000 to 65535 correctly.
rtl837x_port.c prints "called" and "done" around mirroring, PVID, VLAN
and L2 setup, and dhcp.c around discover, request, start and stop. They
land on the console on every boot and config replay, and in the log
once syslog is running. The VLAN line keeps the VLAN, members and
tagged values, only without the function name in front.
On the KP_9000_6XHML_X2 this takes 359 bytes out of BANK1, 88 out of
BANK2 and 24 out of BANK3. BANK1 goes from 431 to 790 bytes free.
dhcp_addopt_request_ip() and dhcp_addopt_server_id() both end with a
copy of four bytes of our MAC to the current position, without moving
the position on. The next option always starts there, so those bytes
are written over before the packet goes out and never reach the wire.
The packet stays the same without the copy, and BANK3 is 102 bytes
smaller on the KP_9000_6XHML_X2.
ip_opt() copies four bytes whatever the option length says, so a
subnet, router, DNS, server id or broadcast option shorter than four
bytes stores the start of the next option as the address. long_opt()
does not look at the length at all and always moves on by six bytes, so
a lease, renewal or rebind option of another length puts the parser out
of step for the rest of the packet.
Both now read the length. An address or time shorter than four bytes is
skipped, a longer one is taken from its first four bytes and stepped
over whole, and a skipped time leaves the previous value alone.
Found in the code, not on the wire; no server here sends such options.
BANK3 is 47 bytes smaller on the KP_9000_6XHML_X2.
