The netbuf_data() function only returns data from the first pbuf in the
chain. We need to use netbuf_first() and netbuf_next() to walk the
pbuf chain and act on each in turn.
* Leaner, meaner crypto module; now with HMAC
Based on my testing, mbedtls pulls in all its algorithm regardless of
whether the NodeMCU crypto module was using them or not. As such, the
space savings from omitting algorithms were only in the tens of bytes.
By switching to using the mbedtls generic message digest interface, the
crypto module itself could be shrunk in size and complexity. Despite
adding support for HMAC on all algorithms (plus including RIPEMD160),
this version is 330 bytes smaller.
* Updated crypto module docs.
* Removed superfluous brackets in crypto docs.

With the IDF asserting full control over the linker scripts and insisting on
the application description being the first entry in the .flash.rodata
section, or previous method of doing link-time arrays stopped working.
Why? Because the build patched in a SHA256 digest straight into our arrays.
With the limited language of the gcc linker scripts I could find no other
way of getting it in cleanly.
The IDF "linker fragments" support can not be made to work for our needs:
- no support for setting alignment before including objects
- no support for declaring symbols
- no support for adding our terminating zeros
- insists on grouping objects by lib rather than by declared grouping,
which means we could at most have a single link-time-array using
the IDF mechanism
- also does not like underscores in section names, but that's just an
annoyance
So, the least bad option that I could come up with was to use a project-wide
makefile snippet to add a target in-between the IDF's generation of the
esp32.project.ld file, and the linking of our NodeMCU.elf. In this target
we read in the esp32.project.ld linker script, check whether we have our
arrays in there, and if not rewrites the linker script.
Oh, and the esp32.project.ld file only came into existence on the IDF 3.3
branch, so I had to change up the IDF to the latest release/3.3 as well.
I would've preferred a stable tag, but the v3.3-beta3 had a really nasty
regression for us (can't add partition entry), so that was a no-go.
* ESP32: Added pulsecnt module
The pulsecnt module let's you use the ESP32's pulse counter capabilities from Lua.
* ESP32: Pulsecnt module. Better/faster callback.
Reduced the amount of callback variables to speed things up and shift more logic to Lua than in the C code.
* ESP32: Completed docs for pulsecnt
* ESP32: Final release of pulsecnt
* ESP32: Production release of pulsecnt
* ESP32: Release (tweaked docs)
* ESP32: Pulse Counter Release. Cleaned up .gitignore
* ESP32: Pulse counter release (changed ch1 gpio to int to match ch0)
* ESP32: Add option to set IP/dns config
This commit adds support for setting:
* Hostname
* Static IP / Dns server (Sta mode)
* Changing AP network ip config
* Setting DNS server IP for DHCP
* ESP32: Documentation for setting IP/dns/hostname config
* Documented new functions
* sethostname() now returns true if success
* ESP32: add support for RS485
This commit adds support for switching UART mode to RS485/IRDA.
Also included are patches for memory leaks then handling UART events other than data.
* ESP32: Documentation for uart.setmode()
* ESP32: Add time modules
New time module for manipulating system time/ calendar and controlling SNTP server
* ESP32: Time module documentation & style fixes
* added documentation for time modules
* style fixes as pointed out by @devsaurus
* ESP32: Time module small fixes
* Couple small fixes
* Esp32: Add SJSON module
This adds SJSON module taken directly from master
* ESP32: Fixes for sjson lib
Fixed compilation not including config header, thus braking some of libs functionality
* ESP32: Upgraded SJSON to master
* Adding qrcodegen module for generating QR Codes
* Added LUA_MODULE_QRCODEGEN KConfig
* Changed qrcodegen.encodeText() to use an options table
Created common.h with new option table helper fns.
* Reworked http.c to use new common.h options table APIs
* esp32: Reinstate tmr.now() function using esp_timer_get_time()
Also added larger limit before wrapping if Lua's number type supports
it.
* Renamed tmr.now() to node.uptime()
Added second return value to indicate timer wrap
- implement file.size for spiffs (#1516)
- fix vfs_lseek() result checking in enduser_setup and clarify SPIFFS_lseek() return value (#1570)
- Handle error condition in file.read() (#1599)
* #2521: Add object-based file API to dev-esp32 branch
Merged in from master@c708828bbe853764b9de58fb8113a70f5a24002d minus
some VFS changes and similar.
* Updated file docs from master
Omitting:
* file.mount()
* reference to rtctime.epoch2cal()
* file.stat()
As these are not available in dev-esp32 branch
Unsure about whether "directories are not supported" is still true
* Set stdout to unbuffered
This fixes issue #2507 esp32 serial console doesn't show output until
enter pressed.
* Moved setvbuf call to app_main immediately after console_init
