* feat(net): support Linux network device query ioctls Add a shared, query-only socket ioctl adapter for SIOCGIFINDEX, SIOCGIFFLAGS, SIOCGIFMTU, and SIOCGIFHWADDR. Resolve devices through the namespace captured by each socket so descriptors retain Linux sock_net() behavior across namespace changes. Move SIOCGIFCONF into the adapter, serialize its multi-device snapshot with RTNL, remove synthetic loopback ordering, and copy data after releasing the lock. Only write back ifc_len, matching Linux while avoiding structure-padding disclosure. Add host/DragonOS coverage for ABI field widths, aliases, user-copy faults, unprivileged access, socket namespace stability, and ifconf padding. Remove the AF_PACKET hardware-address fallbacks so the standard ioctl path is exercised directly. Part of #2233. Signed-off-by: longjin <longjin@dragonos.org> * fix(net): derive user-visible interface flags Derive IFF_RUNNING, IFF_LOWER_UP, and IFF_DORMANT from the interface lifecycle, operational, and carrier state instead of returning cached initialization flags. Keep administratively configured receive-mode flags separate from AF_PACKET reference-counted effective modes, and use one projection for SIOCGIFFLAGS and RTM_GETLINK. Synchronize the interface START state when RTM_NEWLINK changes IFF_UP. Add cross-ABI link state coverage and verify packet memberships update rtnetlink counters without changing configured PROMISC or ALLMULTI flags. Signed-off-by: longjin <longjin@dragonos.org> * test(packet): isolate fanout frames across runs Tag each fanout load-balancing test invocation with a process- and run-specific marker so delayed frames from earlier AF_PACKET traffic cannot be counted as current input. Continue checking the 8/8 distribution while also asserting that every current sequence is delivered exactly once, preserving coverage for broadcasts, duplicates, and drops.

Lightweight Cloud-Native Kernel
DragonOS
Languages 中文|English
DragonOS is a 64-bit operating system with a completely independent kernel, designed for lightweight cloud computing scenarios, offering Linux binary compatibility. It aims to provide lightweight, high-performance solutions for containerized workloads. Developed using Rust for enhanced reliability.
The DragonOS open-source community was established in July 2022 and is entirely commercially neutral. We warmly welcome interested developers and enthusiasts to join us!
DragonOS features excellent and comprehensive architectural design. Compared to other systems of similar scale, DragonOS supports eBPF and virtualization. Currently, we are actively advancing container support, cloud platform compatibility, RISC-V support, as well as porting compilers and application software. Our goal is to achieve large-scale production environment deployment within five years.
DragonOS is rapidly evolving under community-driven development. Currently, DragonOS has implemented approximately 1/4 of Linux interfaces. In the future, we will provide 100% Linux compatibility along with new features.
