License cleanup: add SPDX license identifier to uapi header files with a license

2017-11-02T10:20:11Z

Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

can: cangw: introduce optional uid to reference created routing jobs

2015-06-09T07:39:49Z

Similar to referencing iptables rules by their line number this UID allows to reference created routing jobs, e.g. to alter configured data modifications. The UID is an optional non-zero value which can be provided at routing job creation time. When the UID is set the UID replaces the data modification configuration as job identification attribute e.g. at job removal time. Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: unify identifiers to ensure unique include processing

2014-05-19T07:38:24Z

Armin pointed me to the fact that the identifier which is used to ensure the unique include processing in lunux/include/uapi/linux/can.h is CAN_H. This clashed with his own source as includes from libraries and APIs should use an underscore '_' at the identifier start. This patch fixes the protection identifiers in all CAN relavant includes.

can: add explicit copyrights to can headers

2013-09-21T13:43:12Z

These files are copied to the source code of user space applications (in this case can-utils) and so it makes sense to mention explicitly their copyright. I added the terms of C code that was introduced in the same commit as these headers.

can: gw: add a per rule limitation of frame hops

2013-08-29T20:58:24Z

Usually the received CAN frames can be processed/routed as much as 'max_hops' times (which is given at module load time of the can-gw module). Introduce a new configuration option to reduce the number of possible hops for a specific gateway rule to a value smaller then max_hops.

can: gw: indicate and count deleted frames due to misconfiguration

Add a statistic counter to detect deleted frames due to misconfiguration with a new read-only CGW_DELETED netlink attribute for the CAN gateway. Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: gw: make routing to the incoming CAN interface configurable

2013-01-26T15:59:01Z

Introduce new configuration flag CGW_FLAGS_CAN_IIF_TX_OK to configure if a CAN sk_buff that has been routed with can-gw is allowed to be send back to the originating CAN interface. Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde
