* Update to BearSSL 0.6+ release, add AES_CCM modes
Pull in latest BearSSL head (0.6 + minor additions) release and add AES_CCM
modes to the encryption options.
* Enable the aes_ccm initialization in client/server
* Initial attempt
* Working code with second stack thunking
* Remove #ifdefs in .S file, not needed.
* Clean up thunks and remove separate stack flag
* Fix PIO assembler errors
* Remove #ifdef code changes, ensure same code as PC
Remove "#ifdef ESP8266;...;#else;...;#endif" brackets in BearSSL to
ensure the host-tested code is the same as the ESP8266-run code.
* Move to latest BearSSL w/EC progmem savings
* Merge with master
* Add br_thunk_* calls to do ref counting, painting
Add reference counting br_thunk_add/del_ref() to replace stack handling code
in the class.
Add in stack painting and max usage calculation.
* Add in postmortem stack dump hooks
When a crash occurs while in the second stack, dump the BSSL stack and
then also the stack that it was called from (either cont or sys).
* Update stack dump to match decoder expectations
* Move thunk to code core for linkiage
The thunk code needs to be visible to the core routines, so move it to the
cores/esp8266 directory. Probably need to refactor the stack setup and the
bearssl portion to avoid dependency on bearssl libs in cores/esp8266
* Add 2nd stack dump utility routine
* Refactor once more, update stack size, add stress
Make stack_thunks generic, remove bearssl include inside of cores/esp8266.
Allocate the stack on a WiFiServerSecure object creation to avoid
fragmentation since we will need to allocate the stack to do any
connected work, anyway.
A stress test is now included which checks the total BearSSL second
stack usage for a variety of TLS handshake and certificate options
from badssl.org.
* Update to latest to-thunks branch
* Add BearSSL device test using stack stress
Run a series of SSL connection and transmission tests that stress
BearSSL and its stack usage to the device tests.
Modify device tests to include a possible SPIFFS generation and
upload when a make_spiffs.py file is present in a test directory.
* Use bearssl/master branch, not /to-thunks branch
Update to use the merged master branch of bearssl. Should have no code
changes.
* fwupdate
* fw update to latest version:
WPA working, WEP+Open disabled by default. Need API change.
* helpers to follow sdk updates
* remove compare scripts - made a separate PR for them
* add wep api, restore original espressif comment (wep enabled does not prevent wpa)
* libmain was not up to date
* experimental: DTIM setting in WiFi.setSleepMode(WIFI_LIGHT/MODEM_SLEEP, DTIM-value)
with new getter: .getListenInterval() / .isSleepLevelMax()
* fixes
* fix debug message
* when not using listenInterval, set wifi sleep level to min
* update documentation
* update doc
Pull in latest BearSSL head (0.6 + minor additions) release and add AES_CCM
modes to the encryption options. Enable the aes_ccm initialization in client/server
The EC mul20 and square20 code was identical in two different files,
but because these copies were static, we ended up with an extra 6k of
duplicated code. Updated BearSSL to make them shared, saving 6KB.
* Move ICACHE_* to unique sections, local LD script
Similar to PROGMEM changes, make the name of each ICACHE_* variable/fuction
unique to avoid issues with section conflicts.
Also rename the generated LD linker script to avoid issue with older copies
of the eagle.app.v6.common.ld which were generated by the build process
in a global directory before being moved to the {build.path}. The linker
would use the older, generated *.ld file instead of the generated one, which
would lead to runtime failures on some systems and cause the VTABLE location
to not correspond to the IDE menu selection.
Fixes#5115, and is an update to #5117 and #5116.
* Update boards.txt.py and platform.io build
With the changes in PR #5117, blink and other examples compile but the 8266
gets stuck in a reset loop. Undo the changes from that commit until we can
figure out the root cause and fix it.
BearSSL (https://www.bearssl.org) is a TLS(SSL) library written by
Thomas Pornin that is optimized for lower-memory embedded systems
like the ESP8266. It supports a wide variety of modern ciphers and
is unique in that it doesn't perform any memory allocations during
operation (which is the unfortunate bane of the current axTLS).
BearSSL is also absolutely focused on security and by default performs
all its security checks on x.509 certificates during the connection
phase (but if you want to be insecure and dangerous, that's possible
too).
While it does support unidirectional SSL buffers, like axTLS,
as implemented the ESP8266 wrappers only support bidirectional
buffers. These bidirectional buffers avoid deadlocks in protocols
which don't have well separated receive and transmit periods.
This patch adds several classes which allow connecting to TLS servers
using this library in almost the same way as axTLS:
BearSSL::WiFiClientSecure - WiFiClient that supports TLS
BearSSL::WiFiServerSecure - WiFiServer supporting TLS and client certs
It also introduces objects for PEM/DER encoded keys and certificates:
BearSSLX509List - x.509 Certificate (list) for general use
BearSSLPrivateKey - RSA or EC private key
BearSSLPublicKey - RSA or EC public key (i.e. from a public website)
Finally, it adds a Certificate Authority store object which lets
BearSSL access a set of trusted CA certificates on SPIFFS to allow it
to verify the identity of any remote site on the Internet, without
requiring RAM except for the single matching certificate.
CertStoreSPIFFSBearSSL - Certificate store utility
Client certificates are supported for the BearSSL::WiFiClientSecure, and
what's more the BearSSL::WiFiServerSecure can also *require* remote clients
to have a trusted certificate signed by a specific CA (or yourself with
self-signing CAs).
Maximum Fragment Length Negotiation probing and usage are supported, but
be aware that most sites on the Internet don't support it yet. When
available, you can reduce the memory footprint of the SSL client or server
dramatically (i.e. down to 2-8KB vs. the ~22KB required for a full 16K
receive fragment and 512b send fragment). You can also manually set a
smaller fragment size and guarantee at your protocol level all data will
fit within it.
Examples are included to show the usage of these new features.
axTLS has been moved to its own namespace, "axtls". A default "using"
clause allows existing apps to run using axTLS without any changes.
The BearSSL::WiFi{client,server}Secure implements the axTLS
client/server API which lets many end user applications take advantage
of BearSSL with few or no changes.
The BearSSL static library used presently is stored at
https://github.com/earlephilhower/bearssl-esp8266 and can be built
using the standard ESP8266 toolchain.

patch
- Remove mem_manager.o from libmain.a (replaced with umm_malloc)
- Disable switch from DIO to QIO mode for certain flash chips (saves
IRAM space)
- Add user_rf_cal_sector_set; it points to rf_init_data sector.
- Change the way rf_init_data is spoofed.
This is now done by wrapping spi_flash_read and returning the data we
need during startup sequence.
- Place lwip library into flash using linker script instead of section
attributes (saves IRAM space)
- use new AutoInterruptLock
- add delay to give the RTOS some time to handle TCP
WiFiClient.cpp
- add stopAllexcepted to cancel all TCP excepted one
ClientContext.h
- add getLocalPort()
ESP8266HTTPUpdate.cpp
- close all not needed TCP and UDP
osapi.h
- missing commit from SDK
Fixes issue of reentrant calls to nointerrupts()

interrupts
