LICENSES: Clearly mark dual license only licensesJust like the CDDL the Apache license and the MPL must only be used asa choice in additional to an GPL2 compatible license. Copy over theboilerplate from the CDDL file to the other two after fixing it up tomake it clear the licenses need to be GPL2 compatible, not just themore generic GPL compatible. For example the Apache 2 license is GPL3compatible, but that doesn't matter for the kernel.Also move these licenses to a separate directory and document the rulesin license-rules.rst.Signed-off-by: Christoph Hellwig Reviewed-by: Greg Kroah-Hartman Signed-off-by: Jonathan Corbet List of files: /linux-6.15/LICENSES/dual/Apache-2.0/linux-6.15/LICENSES/dual/CDDL-1.0/linux-6.15/LICENSES/dual/MPL-1.1

ad9f64cd - LICENSES: Add the copyleft-next-0.3.1 license

LICENSES: Add the copyleft-next-0.3.1 licenseAdd the full text of the copyleft-next-0.3.1 license to the kerneltree as well as the required tags for reference and tooling.The license text was copied directly from the copyleft-next project'sgit tree [0].Discussion of using copyleft-next-0.3.1 on Linux started since June,2016 [1]. In the end Linus' preference was to have drivers useMODULE_LICENSE("GPL") to make it clear that the GPL applies when itcomes to Linux [2]. Additionally, even though copyleft-next-0.3.1 hasbeen found to be to be GPLv2 compatible by three attorneys at SUSE andRedhat [3], to err on the side of caution we simply recommend toalways use the "OR" language for this license [4].Even though it has been a goal of the project to be GPL-v2 compatibleto be certain in 2016 I asked for a clarification about what makescopyleft-next GPLv2 compatible and also asked for a summary ofbenefits. This prompted some small minor changes to make compatibilityeven further clear and as of copyleft 0.3.1 compatibility shouldbe crystal clear [5].The summary of why copyleft-next 0.3.1 is compatible with GPLv2is explained as follows: Like GPLv2, copyleft-next requires distribution of derivative works ("Derived Works" in copyleft-next 0.3.x) to be under the same license. Ordinarily this would make the two licenses incompatible. However, copyleft-next 0.3.1 says: "If the Derived Work includes material licensed under the GPL, You may instead license the Derived Work under the GPL." "GPL" is defined to include GPLv2.In practice this means copyleft-next code in Linux may be licensedunder the GPL2, however there are additional obvious gains forbringing contributions from Linux outbound where copyleft-next ispreferred. A summary of benefits why projects outside of Linux mightprefer to use copyleft-next >= 0.3.1 over GPLv2:o It is much shorter and simplero It has an explicit patent license grant, unlike GPLv2o Its notice preservation conditions are clearero More free software/open source licenses are compatible with it (via section 4)o The source code requirement triggered by binary distribution is much simpler in a procedural senseo Recipients potentially have a contract claim against distributors who are noncompliant with the source code requiremento There is a built-in inbound=outbound policy for upstream contributions (cf. Apache License 2.0 section 5)o There are disincentives to engage in the controversial practice of copyleft/ proprietary dual-licensingo In 15 years copyleft expires, which can be advantageous for legacy codeo There are explicit disincentives to bringing patent infringement claims accusing the licensed work of infringement (see 10b)o There is a cure period for licensees who are not compliant with the license (there is no cure opportunity in GPLv2)o copyleft-next has a 'built-in or-later' provisionThe first driver submission to Linux under this dual strategy waslib/test_sysctl.c through commit 9308f2f9e7f05 ("test_sysctl: adddedicated proc sysctl test driver") merged in July 2017. Shortly afterthat I also added test_kmod through commit d9c6a72d6fa29 ("kmod: addtest driver to stress test the module loader") in the same month. Thesetwo drivers went in just a few months before the SPDX license practicekicked in. In 2018 Kuno Woudt went through the process to get SPDXidentifiers for copyleft-next [6] [7]. Although there are SPDX tagsfor copyleft-next-0.3.0, we only document use in Linux starting fromcopyleft-next-0.3.1 which makes GPLv2 compatibility crystal clear.This patch will let us update the two Linux selftest drivers insubsequent patches with their respective SPDX license identifiers andlet us remove repetitive license boiler plate.[0] https://github.com/copyleft-next/copyleft-next/blob/master/Releases/copyleft-next-0.3.1[1] https://lore.kernel.org/lkml/1465929311-13509-1-git-send-email-mcgrof@kernel.org/[2] https://lore.kernel.org/lkml/CA+55aFyhxcvD+q7tp+-yrSFDKfR0mOHgyEAe=f_94aKLsOu0Og@mail.gmail.com/[3] https://lore.kernel.org/lkml/20170516232702.GL17314@wotan.suse.de/[4] https://lkml.kernel.org/r/1495234558.7848.122.camel@linux.intel.com[5] https://lists.fedorahosted.org/archives/list/copyleft-next@lists.fedorahosted.org/thread/JTGV56DDADWGKU7ZKTZA4DLXTGTLNJ57/#SQMDIKBRAVDOCT4UVNOOCRGBN2UJIKHZ[6] https://spdx.org/licenses/copyleft-next-0.3.0.html[7] https://spdx.org/licenses/copyleft-next-0.3.1.htmlCc: Goldwyn Rodrigues Cc: Kuno Woudt Cc: Richard Fontana Cc: copyleft-next@lists.fedorahosted.orgCc: Ciaran Farrell Cc: Christopher De Nicolo Cc: Christoph Hellwig Cc: Greg Kroah-Hartman Cc: Thomas Gleixner Cc: Jonathan Corbet Cc: Thorsten Leemhuis Cc: Andrew Morton Reviewed-by: Kees Cook Signed-off-by: Luis Chamberlain Reviewed-by: Tim Bird Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/LICENSES/dual/copyleft-next-0.3.1
