Jenkins has been updated with new jobs that scan and execute
Jenkinsfiles. These Jenkinsfiles encapsulates all logic for building
and validating the commits in both pull requests and merged pull
requests.
Filestructure is as follows:
.ci/Jenkinsfile - This is the main Jenkinsfile that handles normal
pull request builds as well as merged pull request
post-validation.
Any repository in the MySensors GitHub organization
can implement this file and Jenkins will pick up
and execute it automatically.
.ci/Jenkinsfile-nightly - This perform merged pull request
post-validation using the nightly builds of
the Arduino IDE to provide early compliancy
status of the MySensors library for
upcoming releases of the Arduino IDE
.ci/ - This folder contain all the auxiliary scripts executed by the
Jenkinsfiles as well
Fixes#934
This commit changes the way random numbers are available
with MySensors.
The AVR platform uses a 32 Bit random seed build from a floating
analog pin. The way of the generation of this seed is FIPS 140-2
compliant.
For support MCU with a fast way to generate random data, the
hwGetentropy() command is now available to allow rapid generation
of random data.
The ESP8266 platform uses the internal random source for randomness
for hwGetentropy() and Arduino's random() function.
The NRF5 platform initializes the pseudo random number generator
from internal hardware number generator. The internal AES-ECB unit
generates random data after filling with HWRNG data by AES-CBC.
On Linux getrandom() is implemented via syscall().
signerAtsha204SoftGetNonce speed:
AVR = ~14000us (sha204Soft)
NRF51 = ~152us (AES-CBC), 1739us (old sha204Soft)
NRF52 = ~31us (AES-CBC), 183us (old sha204Soft)
ESP8266 = ~20us (RANDOM_REG32), 380us (old sha204Soft)
All Nonce results tested for FIPS 140-2 compliance successfully.
