selftests: drivers/dma-buf: Fix implicit declaration warns

2021-09-27T15:52:29Z

udmabuf has the following implicit declaration warns: udmabuf.c:30:10: warning: implicit declaration of function 'open'; udmabuf.c:42:8: warning: implicit declaration of function 'fcntl' These are caused due to not including fcntl.h and including just linux/fcntl.h. Fix it to include fcntl.h which will bring in the linux/fcntl.h. In addition, define __EXPORTED_HEADERS__ to bring in F_ADD_SEALS and F_SEAL_SHRINK defines and fix the following error that show up when just fcntl.h is included. udmabuf.c:45:21: error: 'F_ADD_SEALS' undeclared 45 | ret = fcntl(memfd, F_ADD_SEALS, F_SEAL_SHRINK); | ^~~~~~~~~~~ udmabuf.c:45:34: error: 'F_SEAL_SHRINK' undeclared 45 | ret = fcntl(memfd, F_ADD_SEALS, F_SEAL_SHRINK); | ^~~~~~~~~~~~~ Signed-off-by: Shuah Khan

net: update NXP copyright text

2021-09-17T12:52:17Z

NXP Legal insists that the following are not fine: - Saying "NXP Semiconductors" instead of "NXP", since the company's registered name is "NXP" - Putting a "(c)" sign in the copyright string - Putting a comma in the copyright string The only accepted copyright string format is "Copyright NXP". This patch changes the copyright headers in the networking files that were sent by me, or derived from code sent by me. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV

2021-06-08T21:39:07Z

In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

selftests: Clean forgotten resources as part of cleanup()

2021-06-08T21:39:07Z

Several tests do not set some ports down as part of their cleanup(), resulting in IPv6 link-local addresses and associated routes not being deleted. These leaks were found using a BPF tool that monitors ASIC resources. Solve this by setting the ports down at the end of the tests.

selftests: router_scale: Do not count failed routes

2021-06-08T21:39:07Z

To check how many routes are installed in hardware, the test runs "ip route" and greps for "offload", which includes routes with state "offload_failed". Till now, this wrong check was not found because after one failure in route insertion, the driver moved to "abort" mode, which means that user cannot try to add more routes. The previous patch removed the abort mechanism and now failed routes are counted as offloaded. Fix this by not considering routes with "offload_failed" flag as offloaded.
