Missing license and copyright info from libraries and other files

[maqifrnswa]

Many files have missing license and copyright info, which makes redistribution (and inclusion in commercial projects) problematic. I can do a pull for the assumed LGPL and GPL ones, but I don't know who the copyright holders are.

The most important ones to address are the libraries, since they are the most likely to be included in other projects and need clear distribution license/copyrights.

Libraries (assume LGPL, but no header or copyright info):

Wifi: ./libraries/WiFi/WiFi.cpp ./libraries/WiFi/WiFi.h ./libraries/WiFi/WiFiClient.cpp ./libraries/WiFi/WiFiClient.h ./libraries/WiFi/WiFiServer.cpp ./libraries/WiFi/WiFiServer.h ./libraries/WiFi/utility/debug.h ./libraries/WiFi/utility/server_drv.cpp ./libraries/WiFi/utility/server_drv.h ./libraries/WiFi/utility/socket.c ./libraries/WiFi/utility/socket.h ./libraries/WiFi/utility/spi_drv.cpp ./libraries/WiFi/utility/spi_drv.h ./libraries/WiFi/utility/wifi_drv.cpp ./libraries/WiFi/utility/wifi_drv.h ./libraries/WiFi/utility/wifi_spi.h ./libraries/WiFi/utility/wl_definitions.h ./libraries/WiFi/utility/wl_types.h

See also #1847 for some follow ups. I'll strike-through the completed files by editing the original issue.

I just found this in one of the fedora or opensuse rpms:

# The "extra" wifi components are licensed non-free and do not fall under the
# "firmware" execption.
rm -rf hardware/arduino/avr/firmwares/wifishield
rm -rf libraries/WiFi/extras
# As mentioned earlier, binary forms are removed here.
find -type d \( -name macosx -o -name windows \) -print0 | xargs -0 rm -rf
find -name '*.tgz' -delete
find -name '*.tar.gz' -delete
find -name '*.elf' -delete
find -name '*.class' -delete
find -name '*.jar' -delete
find -name '*.so' -delete
find -name '*.hex' -delete

This refers to those files: https://github.com/arduino/Arduino/tree/master/hardware/arduino/avr/firmwares/wifishield https://github.com/arduino-libraries/WiFi101-FirmwareUpdater-Plugin

The firmware updater seems to be GPL, but which license does the wifishielf firmware has? Or do you have any idea why they got removed in their rpm?

Bootloaders (optiboot is GPL v2 according to http://code.google.com/p/optiboot/ but I can't find copyright info or license info attributing that in Arduino): ./hardware/arduino/bootloaders/optiboot/optiboot.c

Isn't it here?: https://github.com/arduino/Arduino/blob/1.8.3/hardware/arduino/avr/bootloaders/optiboot/optiboot.c#L59-L77

[giallu]

I am the current Fedora RPM maintainer and I am also wondering why the .hex files were removed in our package. Apparently, that was made in response to this opened issue: https://bugzilla.redhat.com/show_bug.cgi?id=949158

However, I can see the corresponding sources for the hex files are included and with a free license so I will revert the change for now.

[cmaglie]

@giallu you should ask the Fedora RPM maintainers to do so, since it's their decision to remove the .hex files. As Arduino we are not involved in any way with the package maintenance.

[cmaglie]

sorry just re-read your message again... :-)

However, I can see the corresponding sources for the hex files are included and with a free license so I will revert the change for now.

I think it's the right choice, some of those .hex are needed for the "Burn Bootloader" command to work.

LiquidCrystal: ./libraries/LiquidCrystal/LiquidCrystal.cpp ./libraries/LiquidCrystal/LiquidCrystal.h

There is now a license defined in the library's readme: https://github.com/arduino-libraries/LiquidCrystal/blob/master/README.adoc

Ethernet: ./libraries/Ethernet/Dhcp.cpp ./libraries/Ethernet/Dhcp.h

There is now a license defined in the library's readme: https://github.com/arduino-libraries/Ethernet/blob/master/README.adoc

Is that sufficient?
