The motivation for this work is to improve the test coverage and reliability of the Netlink subsystem, specifically for the core af_netlink.c and genetlink.c components. While the subsystem is critical for kernel-userspace communication, its coverage by the existing selftests is quite limited.
To quantify the improvement, these new selftests achieve the following line coverage (as measured by gcov): - net/netlink/af_netlink.c: 84.0% - net/netlink/genetlink.c: 88.8% Integrating these tests into the upstream suite will provide long-term stability and make it safer to refactor or add new features to the Netlink core in the future. пт, 12 сент. 2025 г. в 23:17, Jakub Kicinski <[email protected]>: пт, 12 сент. 2025 г. в 23:17, Jakub Kicinski <[email protected]>: > > On Fri, 12 Sep 2025 22:53:23 +0300 Yana Bashlykova wrote: > > This series adds comprehensive testing infrastructure for Netlink > > and Generic Netlink > > > > The implementation includes both kernel module and userspace tests to > > verify correct Generic Netlink and Netlink behaviors under > > various conditions. > > What is the motivation for this work?
