The installer Makefile called whatever sdcc was on the PATH, so an
installer built by hand came out of the system compiler, without the
fixes in sdcc/. Use the same toolchain/sdcc-<cksum> as the main Makefile,
built on demand by sdcc/build.sh if a bare installer build gets there
first, and keep CC= on the command line as the way to pick another
compiler. The README example shows the new command lines.
Review feedback on #560 (DrDoof):
- A login that came with a cookie that is still valid took a second
slot. The first one looked fresh, so the next login could push out
someone who is using the switch. The slot of the cookie now gets the
new id.
- Changing the password leaves no old login valid: session_init() from
parse_passwd(). With one session the next login pushed a leftover one
out, with several it would stay valid until the next restart.
- The 32-bit comparison of the last use times moves into a leaf function,
so the compiler does not give it a 4-byte scratch in internal RAM.

The web server's bank had no room left for the four sessions once the
original firmware's more robust header handling came in. Picking a slot,
checking a cookie and starting a session move to sessions.c in bank 3;
httpd.c only calls session_init(), session_check() and session_new().
The random id is written straight into the reply, which drops
gen_random_hex_chars() from bank 1.

Logging in from a second browser ended the first one's session at its next
request: two browsers open on the switch logged each other out every few
seconds. Up to four sessions now, each with its own cookie and expiry; a
fifth login replaces the least recently used. The expiry check is a leaf
function so its 32-bit scratch stays out of internal RAM (stack still
159 bytes with HEALTH).

html_min was phony, so every make deleted output/html_min and minified
all of html/ again, even with nothing changed. A stamp file now stands for
the minified copy and depends on the sources and on minify.py. A list of
the source names, rewritten only when it changes, is a dependency too, so
adding or removing a file in html/ still redoes the copy and a removed
file does not stay behind in the image. If output/html_min is missing,
the stamp is remade in the same run.
The note on version.h in webui-compression.md still said it was phony.
Three more bench scenarios around the closing boundary. Every value
of the last image byte, uploaded whole and split right after the
payload, must end the part. A run of CR before the boundary of even
length passed before the fix and an odd one did not, so both are
checked. An image made of CR only, longer than a flash page, and one
made of repeated "\r\n-" exercise the broken matches back to back:
each one appends to the page buffer without a byte written, and the
page flush after both paths has to keep up.
stream_upload() matches the closing multipart boundary byte by byte.
When a byte breaks a partial match, the matched prefix goes to flash as
data, and so does the breaking byte, without being compared against the
start of the boundary.
The boundary starts with "\r\n--", so an image whose last byte is '\r'
never completes: that '\r' starts a match, the '\r' of the boundary
breaks it and is written as data, and the rest of the boundary no
longer matches. The browser waits for a reply that never comes.
Flush the matched prefix and look at the breaking byte again from the
start of the boundary. A boundary may not contain CR, so no longer
suffix of the matched prefix can start a new match.
The 8051 assembler sign-extends every value to 24 bits, so the top
byte of a __sfr32 address list like 0xa4a5a6a7 comes out as 0xff.
The patch keeps 32-bit arithmetic while leaving the 24-bit T line
addresses alone, so the relocations are unchanged. Proposed upstream
in the bug thread. With it SFR_DATA_U32 can be used again, which
saves about 240 bytes of code in REG_SET.
The workflow and the Dockerfile install what building SDCC needs instead
of the distribution's sdcc, and the workflow caches toolchain/ keyed on
the contents of sdcc/.
Released SDCC 4.5.0 and 4.6.0 miscompile some of our code in the mcs51
register allocator (SDCC bugs 4153 and 4154, fixed in trunk r17025 and
r17039). The first make now downloads the 4.6.0 sources, checks their
sha256, applies the two fixes from sdcc/ and installs the compiler into
toolchain/, named after a checksum of sdcc/, so a changed patch builds a
new one. make CC=sdcc still uses an installed compiler.
The masks were 0, so 0x3e2 was ORed into the reset value 0xbff and both
SerDes stayed off on boards without 10G ports (n_10g == 0), e.g. the
HC-SWTG124AS. With SDS 0 off RTL837X_REG_SEC_COUNTER does not hold a
written value: it reads 0, so NTP never retried after a failed first
attempt at boot and froze the clock after a sync.
Tested with regset on an HC-SWTG124AS: the register keeps a write with
SDS 0 in SGMII or 10GR, not with SDS 0 off (also not with only SDS 1
on).
Firefox filled a saved login into the System tab's password fields and
its user name into the NTP poll interval, the input before them. That
input event marked the Time card as edited, so ntpLoad() left NTP off,
the server empty and the time zone at UTC-12:00.
