A stack buffer overflow can be caused deliberately as part of an attack known as stack smashing. If the affected program is running with special privileges, or accepts data from untrusted network hosts (e.g. a webserver) then the bug is a potential security vulnerability. If the stack buffer is filled with data supplied from an untrusted user ...
The kerneloops software can collect and submit kernel oopses to a repository such as the www.kerneloops.org website, [7] which provides statistics and public access to reported oopses. A simplified crash screen was introduced in Linux 6.10, similar to the Blue Screen of Death on Windows. [8]
Netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.Netfilter offers various functions and operations for packet filtering, network address translation, and port translation, which provide the functionality required for directing packets through a network and prohibiting packets from ...
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 ...
In strace version 4.7, released in May 2012, [12] all non-Linux code had been removed; [13] since strace 4.13, [14] the project follows Linux kernel's release schedule, and as of version 5.0, [15] it follows Linux's versioning scheme as well. In 2012 strace also gained support for path tracing and file descriptor path decoding. [16]
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 ...
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.
The Linux kernel's network stack contains several other buffers, which are not managed by the network scheduler. [a] Berkeley Packet Filter filters can be attached to the packet scheduler's classifiers. The eBPF functionality brought by version 4.1 of the Linux kernel in 2015 extends the classic BPF programmable classifiers to eBPF. [17]
