26 OK, so you've got approval to integrate code, and you want to know how to
27 properly communicate the license terms. What do you do next?
29 0. Determine whether your code should be covered by Oracle copyright,
30 CDDL, and/or a third party license. If only Oracle copyright and/or
31 CDDL, then skip to step 3.
33 1. Scan the source code and extract all of the third party licenses
34 into one or more separate files.
36 This information may be present in comments in source code, or may
37 already be provided as separate files. For example, GPL license
38 terms are often found in files named "COPYING."
40 A. In general, you'll name these files "THIRDPARTYLICENSE," and
41 you'll put one in each source directory (i.e. one per library,
42 or one per command, or one per kernel module.)
44 EXAMPLE: usr/src/uts/common/io/pcan/THIRDPARTYLICENSE
46 If this file proves unmanageable, or you're adding licenses
47 that really are independent of each other, you may instead
48 create multiple "THIRDPARTYLICENSE.foo" files, where "foo"
49 obviously corresponds to the license in question.
51 EXAMPLE: usr/src/lib/libsmbfs/smb/THIRDPARTYLICENSE.*
53 B. If you planned ahead and included graceful delimiters in your
54 source code, the THIRDPARTYLICENSE files may actually be build
55 targets in your Makefiles.
57 EXAMPLE: usr/src/cmd/perl/Makefile
59 If the corresponding copyright will change dates frequently,
60 then this approach can work well, because you won't need to
61 update the license files manually.
63 If you do this, then your license file should be a dependency of
64 both the all and install targets, and should be removed via
65 clobber, usually by way of CLOBBERFILES.
67 2. Give each of the license files a corresponding ".descrip" file with
68 a terse explanation of the contents. Something like "MJN DRIVER"
69 or "PORTIONS OF ARCANE FUNCTIONALITY" is sufficient.
71 EXAMPLE: usr/src/cmd/refer/THIRDPARTYLICENSE.descrip
73 3. Figure out which packages deliver objects that are built using the
74 new source, and add license actions to the package manifest(s).
76 A. It's extremely rare for a package NOT to include a Sun copyright
77 and CDDL. If your package is one of the 99 percent that should
78 have a Sun copyright and CDDL, then your package should have license
81 license lic_CDDL license=lic_CDDL
82 license cr_Sun license=cr_Sun
84 B. If your package delivers ONLY header files, and has multiple different
85 copyrights or licenses, you can use
87 license license_in_headers license=license_in_headers
88 license path/to/most/common/copyright/file \
89 license=path/to/most/common/copyright/file
90 license path/to/most/common/license/file \
91 license=path/to/most/common/license/file
93 C. For your new license files, the path you use in your license
94 actions should be relative to ${SRCTOP}.
96 D. Empty packages: if your package delivers nothing (or, more strictly
97 speaking, nothing besides directories) you should include the Sun
98 copyright but not the CDDL.
100 E. As with any other action that is architecture dependent, license
101 actions may be preceded by $(blah_ONLY), where "blah" corresponds
104 If you don't add the appropriate license actions to package
105 manifests, then your license and description files will show up as
106 unreferenced in the build.
