* 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.
This allows requesting environment variable values set in the C++ test
code, from python mock code. Use case is cross-checking test
results against values expected by the host side part of the test.
Previously device tests included information such as access point SSID/password at compile time. This made it difficult to compile test binaries once and then send them to multiple test runners for execution.
This change adds a command to the test library to set environment variable on the target device: “setenv key value”. C library setenv/getenv facility is used to store variables.
Test runner, tests, and makefile are updated to use this functionality.
* tests/device/Makefile: use bourne shell compatible "." instead ot "source" (ubuntu's dash does not understand it)
* tests/device: make BEGINTIMEOUT a new error return value instead of a test-process-breaking exception
