pwru is an eBPF-based tool for tracing network packets in the Linux kernel with advanced filtering capabilities. It allows fine-grained introspection of kernel state to facilitate debugging network connectivity issues.

...It can log OpenCL calls or errors, time expensive functions, modify the devices or extensions returned to the program, or track OpenCL objects. Tracking OpenCL objects also allows CLIntercept to detect some common programming errors, such as leaks, mismatched calls to retain/release, situations that are not thread safe, and errors with mapped images or buffers, including buffer overwrites. Any of these can be missed by the OpenCL implementation and led to incorrect behavior or even crash the system.

gdbplus is an extension to formal releases of GNU debugger gdb. On top of gdb functions, the extension provides additional commands to analyze heap data, object relationship, etc. These power features may shed light on tough issues such as memory corruption, debugging highly optimized code, etc.

... - it uses the hardware paging system for immediate error detection (most other memory checkers look for modified memory in no mans land) - it is very fast compared to other hardware memory checkers because it makes fewer changes to the paging tables - it can track the original release location when debugging duplicate free problems - it is designed for large scale integration with the ability to call user defined fail functions
