The PR removed the bulk of non-newlib headers from the NodeMCU source base.
app/libc has now been cut down to the bare minimum overrides to shadow the
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately,
but it's no worse than it has been before.
This enables our source files to compile successfully using the standard header files,
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and
memwhatever()s. These end up, through macro and linker magic, mapped to the
appropriate SDK or ROM functions.
* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.
* Update TLS protocol support
TLS1.0 is past PCI's EOL; BEAST is no more
Enable elliptic curve key exchanges
Do not enable the smallest ECs for security
Do not enable the largest ECs for computational time
Do not enable 25519 (sad) because it doesn't go across the wire
Drop non-PFS key exchanges
Drop ARC4, Blowfish, DES, genprime, XTEA code
Drop renegotiation support completely
It takes so much heap that it's not likely to work out well
Tidy handling of SSL_BUFFER_SIZE
Update docs
Drop mention of startcom, since they are no more, for letsencrypt
* Update mbedtls to 2.7.7
Preserve our vsnprintf and platform hacks
* Introduce TLS maximum fragment size knob
Reduce buffer size to 4Ki by default and advertize that. That's the
largest we can advertize with the TLS MFL extension, so there's no
point in making them larger. The truly adventurous can re-raise
SSL_BUFFER_SIZE and undefine the SSL_MAX_FRAGMENT_LENGTH_CODE and get
back to the earlier behavior.
* Default to mbedTLS debug with DEVELOP_VERSION

Apply local changes to build:
app/include/lwip/app/espconn.h pulls changes (and license decl) from
upstream SDK. Makefile is altered to use this file ahead of the
SDK's.
Remove lwip's sntp support, since it was never really wired in anyway.
See https://github.com/nodemcu/nodemcu-firmware/issues/2042 for more
information. Patch Makefile to strip time.o, the consumer of lwip's
sntp functionality, from libmain.a, resulting in much
easier-to-understand error messages.
This has consequences for mbedtls. The simplest thing to do, which is,
impressively, not a change in behavior, is to completely disable TLS
certificate time validation; a later patch can optionally couple this to
RTCTIME support.
Similarly, it happens that the sqlite3 import was calling time(), but
this was not going to work out well for it. Just stub it out to always
return unix timestamp 0, as would have happened anyway.
Changes unprocessed:
0007-sync-from-080c37e1.patch
0008-feat-lib-Compile-some-libraries-with-ffunction-secti.patch
These two make changes to the linker script; perhaps
they are worth porting over, but I have not done so
here.
This is build-tested (ADC, BIT, COLOR_UTILS, CRON, CRYPTO, DHT, ENCODER,
FILE, GPIO, HTTP, I2C, MQTT, NET, NODE, OW, PCM, PERF, PWM, RTCFIFO,
RTCMEM, RTCTIME, SNTP, SPI, SQLITE3, STRUCT, TLS, TMR, UART, WIFI,
WS2812, WS2812_EFFECTS) and boots, but only limited run-time testing has
been performed. Testing done does, however, include having made a few
TLS connections through the HTTP module, so things are not hopelessly
broken, at the very least.
The esp_init_data_default.bin is now extracted from the SDK (and its
patch file, if present), and the contents are automatically embedded
into user_main.o.
To work around the pesky "rf_cal[0] !=0x05" hang when booting on a chip
which doesn't have esp_init_data written to it.
It is no longer possible to do the writing of the esp_init_data_default
from within nodemcu_init(), as the SDK now hangs long before it gets
there. As such, I've had to reimplement this in our user_start_trampoline
and get it all done before the SDK has a chance to look for the init data.
It's unfortunate that we have to spend IRAM on this, but I see no better
alternative at this point.
Input during startup (especially while doing initial filesystem format)
ran the risk of filling up the task queue, preventing the start_lua task
from being queued, and hence NodeMCU would not start up that time.

- Stop fighting against the SDK in terms of owning/writing the init_data block.
NodeMCU included a default init_data block because originally the SDK did
not, but by now it's not needed.
- Expose a way to reconfigure the ADC mode from Lua land. With most people
using the cloud builder and not able to change the #define for byte 107
this has been a pain point.
- Less confusion about which init_data has been used. Lua code can now simply
state what mode it wants the ADC to be in, and not worry about the rest of
the init_data complexities such as the init_data changing location due to
flashing with wrong flash_size setting, or doing/not doing a chip-erase
before loading new NodeMCU firmware.
AFAIK no one uses the wifi.startsmart() and wifi.stopsmart(). Removing
them frees up an extra 20-25K of Flash to use as filesystem. So I have
added a new config define WIFI_SMART_ENABLE which is enabled by default
so the default functionality is the same, but if this is commented out
then this code is omitted.
I have also removed wofs and upgrade from this build as we no longer
support these.
As with the last commit this rolls up the follwowing, but include the various
review comments on the PR.
- **Documentation changes**. I've added the taks FAQ as a stub new Extension
developer FAQ, and split the old FAQ into a Lua Developer FAQ and a Hardware
FAQ.
- **Tasking I/F**. New `app/task/Makefile`, `app/task/task.c`,
`app/include/task/task.h` and `app/Makefile` as per previous commit. Cascade
changes to `app/driver/uart.c`, `app/include/driver/uart.h`,
`app/user/user_main.c` and `app/modules/node.c`
- **GPIO Rework** to `app/modules/gpio.c` and `pin_map.[hc]`, `platform.[hc]`
in `app/platform`
- **Other Optimisations** Move the `platform_*_exists()` from
`app/platform/common.c` to static inline declarations in `platform.h` as
this generates faster, smaller code. Move lgc.a routines out of iram0.
This addresses the issue where a server would otherwise reject a valid
connection attempt from a rebooted node, due to the server thinking that
packet belonged to a recently closed session. By starting off the local
TCP port numbers at random* points each boot the risk of port reuse
across a reboot is significantly reduced.
*) As random as can be had via the lower 12 bits of the ccounter.
Added Lua module rtctime to interface with it.
This keeps as accurate time as is possible on the ESP8266, including across
deep sleeps (provided rtctime.dsleep() is used rather than node.dsleep()).
Intended to be used together with NTP for high accuracy time keeping. The
API is via rtctime.{get,set}timeofday(), working from Unix epoch.
Note that 160MHz CPU clock is not currently supported by the rtctime code,
as it is only aware of the 52MHz boot clock and the regular 80Mhz default
clock.
See rtctime.h for detailed info on how this all works.
Accessing 8bit and 16bit constants from ROM rather than RAM comes with a
performance cost, as these loads go through the load/store exception
vector. Any performance critical constants can be forced back into RAM
as RAM_CONST_ATTR.
The entry point has changed from call_user_start() to user_start_trampoline()
in order for the exception handler to be installed early enough.
