Add support for using doubles in the LUA53 build. (#3225) 2020-11-07 22:38:40 +01:00
Nathaniel Wesley Filardo d480003a40 tls: fix new verification API
Because the old API was inactive, we were setting
MBEDTLS_SSL_VERIFY_NONE even after we'd parsed the certificate.

tls tests now include a deliberate certificate mismatch; this was
discovered by moving the mqtt tests over to the new API.

Nathaniel Wesley Filardo af426d0315 Networking rampage and accumulated fixes (#3060)
* espconn: remove unused espconn code, take 1

This is the easiest part of https://github.com/nodemcu/nodemcu-firmware/issues/3004 .
It removes a bunch of functions that were never called in our tree.

* espconn: De-orbit espconn_gethostbyname

Further work on https://github.com/nodemcu/nodemcu-firmware/issues/3004

While here, remove `mqtt`'s charming DNS-retry logic (which is neither
shared with nor duplicated in other modules) and update its :connect()
return value behavior and documentation.

* espconn: remove scary global pktinfo

A write-only global!  How about that.

* net: remove deprecated methods

All the TLS stuff moved over there a long time ago, and
net_createUDPSocket should just do what it says on the tin.

* espconn_secure: remove ESPCONN_SERVER support

We can barely function as a TLS client; being a TLS server seems like a
real stretch.  This code was never called from Lua anyway.

* espconn_secure: more code removal

* espconn_secure: simplify ssl options structure

There is nothing "ssl_packet" about this structure.  Get rid of the
terrifying "pbuffer" pointer.

Squash two structure types together and eliminate an unused field.

* espconn_secure: refactor mbedtls_msg_info_load

Split out espconn_mbedtls_parse, which we can use as part of our effort
towards addressing https://github.com/nodemcu/nodemcu-firmware/issues/3032

* espconn_secure: introduce TLS cert/key callbacks

The new feature part of https://github.com/nodemcu/nodemcu-firmware/issues/3032
Subsequent work will remove the old mechanism.

* tls: add deprecation warnings

* luacheck: net.ifinfo is a thing now

* tls: remove use of espconn->reverse

* mqtt: stop using espconn->reverse

Instead, just place the espconn structure itself at the top of the user
data.  This enlarges the structure somewhat but removes one more layer
of dynamic heap usage and NULL checks.

While here, simplify the code a bit.

* mqtt: remove redundant pointer to connect_info

Everywhere we have the mqtt_state_t we also have the lmqtt_userdata.

* mqtt: doc fixes

* mqtt: note bug

* tls: allow :on(...,nil) to unregister a callback

Nathaniel Wesley Filardo 863dfb59ed SSL rampage (#2938)
* Remove stale putative MD2 support

This hasn't worked in a while, presumably since one of our upstream
merges.  Don't bother making it work, since MD2 is generally considered
insecure.

* Land mbedtls 2.16.3-77-gf02988e57

* TLS: remove some dead code from espconn_mbedtls

There was some... frankly kind of scary buffer and data shuffling if
ESP8266_PLATFORM was defined.  Since we don't, in fact, define that
preprocessor symbol, just drop the code lest anyone (possibly future-me)
be scared.

* TLS: espconn_mbedtls: run through astyle

No functional changes

* TLS: espconn_mbedtls: put the file_params on the stack

There's no need to malloc a structure that's used only locally.

* TLS: Further minor tidying of mbedtls glue

What an absolute shitshow this is.  mbedtls should absolutely not
be mentioned inside sys/socket.h and app/mbedtls/app/lwIPSocket.c is not
so much glue as it as a complete copy of a random subset of lwIP; it
should go, but we aren't there yet.

Get rid of the mysterious "mbedlts_record" struct, which housed merely a
length of bytes sent solely for gating the "record sent" callback.

Remove spurious __attribute__((weak)) from symbols not otherwise
defined and rename them to emphasize that they are not actually part of
mbedtls proper.

* TLS: Rampage esp mbedtls glue and delete unused code

This at least makes the shitshow smaller

* TLS: lwip: fix some memp definitions

I presume these also need the new arguments

* TLS: Remove more non-NodeMCU code from our mbedtls

* TLS: drop support for 1.1

Depending on who you ask it's either EOL already or EOL soon, so
we may as well get rid of it now.

Evict c_types.h, tidy up a other c_prefixes. (#2841) 2019-07-23 14:22:38 +10:00
Johny Mattsson 526d21dab4 Major cleanup - c_whatever is finally history. (#2838)
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.

Nathaniel Wesley Filardo 6e95d74fbd Update TLS protocol support (#2587)
* 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

		Upstream files only

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.
