XDP (eXpress Data Path) is an eBPF-based high-performance network data path used to send and receive network packets at high rates by bypassing most of the operating system networking stack. It is merged in the Linux kernel since version 4.8. [2] This implementation is licensed under GPL. Large technology firms including Amazon, Google and ...
kdump (Linux) – Linux kernel's crash dump mechanism, which internally uses kexec System.map – contains mappings between symbol names and their addresses in memory, used to interpret oopses References
www.kernel.org /pub /software /network /ethtool / ethtool is the primary means in Linux kernel -based operating systems (primarily Linux and Android ) for displaying and modifying the parameters of network interface controllers (NICs) and their associated device driver software from application programs running in userspace .
SocketCAN is a set of open source CAN drivers and a networking stack contributed by Volkswagen Research to the Linux kernel. SocketCAN was formerly known as Low Level CAN Framework (LLCF). Typical CAN communication layers. With SocketCAN (left) or conventional (right). Traditional CAN drivers for Linux are based on the model of character devices.
After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
Linux kernel: network device drivers and network stack. Utility programs are not depicted, they communicate through the SCI with the different components of the kernel. To connect computers with each other, various communications protocols have been developed, e.g. IEEE 802.3 (Ethernet), IEEE 802.11 ("wireless"), IEEE 802.15.1 (Bluetooth ...
The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space. This offloading achieves higher ...
When a socket is ungraciously closed, either by the user or because of a process crash, the kernel socket cleanup code will by its own initiative issue a FIN/ERROR message to the peer. When contact to a cluster node is lost, the local link layer will issue FIN/ERROR messages to all sockets having connections towards that node.
