* Signing support with MAX_PAYLOAD>32
Support in the signing backends to handle configurations
where MAX_PAYLOAD is more than 32 bytes.
Fixes#748
* Support big message signatures
Support for signing messages larger than 32 bytes.
This is not fully testable with the current version of
the library but the change would add theoretical support
for signing any sized messages.
Fixes#749
* Have gw properly indicate whitelisting preferences
If the gateway hold a signing whitelist, inform all
nodes of this requirement and not just nodes that hold
whitelists themselves.
Fixes#806
* Harden security
The flag MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL
has been removed. Gateway will now request signatures
from everyone by default.
In addition to this, no nodes in the network will allow
clearing of signing/whitelisting preferences by OTA
commands by default.
If the old behaviour is needed (suitable for gradual
signing roll out and development purposes) a new flag,
MY_SIGNING_WEAK_SECURITY can be set.
Fixes#807
* Signing debug messages rewritten
All signing related debug has been rewritten to
better match other core debug printouts.
Also, backends are updated to have a smaller
implementation delta.
* Simplified signing option implemented
Enable by MY_SIGNING_SIMPLE_PASSWD. Signing, and signing requirements
will be enabled, as will encryption. Whitelisting is optional.
The value provided to MY_SIGNING_SIMPLE_PASSWD is used as HMAC and AES
key. Whitelists use the first 8 bytes of the password and the ninth
byte from the node ID as serial.
Password is required to be at least 8 characters wide. It is zero
padded if it is not long enough to cover the AES (16 bytes) and HMAC
(32 bytes) keys. It is not recommended to have a password shorter than
32 bytes, and there is no need for a password longer than 32 bytes.
* Add documentation section for signing debug
* Add nRF5 encryption to simple signing option
* Restructure MySigning documentation
* Minor fixes for Linux
RPi and Linux refactor.
Add GPIO Sysfs for GPIO operations.
Update configure script.
Fix some cppcheck warnings.
Add serial emulation that prints to stdout.
Fix some file headers.
* Add option to not install a init script
* Added autotools default install prefix
* Add autotools ${DESTDIR} to the install paths
* Add option to specify platform type
Add option to set an external arduino libraries directory.
All libraries from this folder will be compile and available for use
in the gateway.
Some Arduino libraries can be used on Linux/RPI with minor adjustments,
but there are some that will have to be completely rewritten.
The build process uses a separate folder for objects and binary files
which can be set by the user.
Initialize the bcm2835 inside a class constructor to fix cases where
pin operations are used before hwInit().
Fix SPI pins default values.
Fix activation interrupt functions.
Fix some headers.
Rename gateway binary and services to mysgw.
