opkg is GPLv2+ licensed but it has optional support for sha256 checksums which
was GPLv3+ licensed. This code is not built unless '--enable-sha256' is passed
to the configure script, the default is equivalent to '--disable-sha256'.
However, the header 'sha256.h', which is GPLv3+ licensed, is in the list of
header files to be installed and thus could end up in the libopkg-dev package.
As this header is installed to '/usr/include/libopkg' it is very unlikely that
it will ever be used. However, if you're uncomfortable with GPLv3 code going
anywhere near your target filesystem you won't want this to happen.
The simplest solution is to replace the sha256 implementation in opkg with the
implementation from coreutils-6.9 which is licensed under GPLv2+. This is
committed to the opkg subversion repository as r652/r653.
The only intervening commit between r650 (previous SRCREV) and this is r651,
which integrates 'obsolete_automake_macros.patch' into the opkg sources. Thus
this patch isn't needed in oe-core anymore.
(Note: Before 873689bbabba25e7be5c12317c04519a7bc8d0ef, this header is only
installed if opkg is built in its source tree (ie. ${B}=${S}). After that commit
the header will always be installed)

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
http://www.openembedded.org/
Where to Send Patches
=====================
As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.
bitbake:
bitbake-devel@lists.openembedded.org
meta-yocto:
poky@yoctoproject.org
Most everything else should be sent to the OpenEmbedded Core mailing list. If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix
of oe-core and poky-specific files.
