This adds the SPDX-License-Identifier license headers to the majority of our source files to make it clearer exactly which license files are under. The bulk of the files are under GPL v2.0 with one found to be under V2.0 or later, some under MIT and some have dual license. There are some files which are potentially harder to classify where we've imported upstream code and those can be handled specifically in later commits. The COPYING file is replaced with LICENSE.X files which contain the full license texts.

BitBake 'Fetch' implementations
|
|
|
|
This implementation is for Secure Shell (SSH), and attempts to comply with the
|
|
IETF secsh internet draft:
|
|
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
|
|
|
|
Currently does not support the sftp parameters, as this uses scp
|
|
Also does not support the 'fingerprint' connection parameter.
|
|
|
|
Please note that '/' is used as host, path separator not ':' as you may
|
|
be used to, also '~' can be used to specify user HOME, but again after '/'
|
|
|
|
Example SRC_URI:
|
|
SRC_URI = "ssh://user@host.example.com/dir/path/file.txt"
|
|
SRC_URI = "ssh://user@host.example.com/~/file.txt"
