X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 28 Jun 2018 22:45:37 -0000 Hi All, The following patches are to fix a problem with detaching a KNI interface using rte_kni_release and to add a new API function to allow users to change the link status (up/down, speed, etc) of the interface in the linux kernel. In previous versions, it was impossible to release a KNI interface without waiting for the timeout in kni_net_process_request to expire if the interface is in the UP state. The solution to this issue was to separate the process of releasing the netdev device from the linux kernel from actually freeing the KNI interface in the kernel and in the RTE library by introducing a new API function, rte_kni_free(). The last patch : 'kni: add API to set link status on kernel interface' adds a new API function to allow the DPDK user to change the link speed and status reported by the netdev in the linux kernel. This resolves issues with allowing automatic network configuration applciations such as NetworkManager to assign addresses and for user space applications to be able to open sockets on these interfaces, as some operations rely on the link status being up before they work properly. This last patch is included in this series because both new "features" introduce new ioctls to the rte_kni kernel module, so the order in which the patches get applied affects which number each new ioctl gets. I thought it better to bundle them together to try to get them applied as a series to avoid any issues with this. Please have a look! thanks dan Dan Gora (10): kni: remove unused variables from struct kni_dev kni: separate releasing netdev from freeing KNI interface kni: don't touch struct kni_dev after freeing kni: add rte_kni_free to KNI library kni: don't run rte_kni_handle_request after interface release kni: increase length of timeout for KNI responses kni: update kni test for rte_kni_free kni: add rte_kni_free to KNI example app kni: add rte_kni_free to KNI vdev driver kni: add API to set link status on kernel interface drivers/net/kni/rte_eth_kni.c | 6 +- examples/kni/main.c | 4 +- kernel/linux/kni/kni_dev.h | 5 +- kernel/linux/kni/kni_misc.c | 156 ++++++++++++++++-- kernel/linux/kni/kni_net.c | 7 +- .../eal/include/exec-env/rte_kni_common.h | 20 +++ lib/librte_kni/rte_kni.c | 75 ++++++++- lib/librte_kni/rte_kni.h | 51 +++++- test/test/test_kni.c | 20 +++ 9 files changed, 313 insertions(+), 31 deletions(-) -- 2.18.0.rc1.1.g6f333ff2f
