- Add a libdwfl fallback that opens absolute module paths through /proc/<pid>/root so remote Pyxis/Enroot targets can resolve libraries that are only visible inside the container filesystem. - Associate the analyzed PID with each DWFL module before attach so the ELF lookup callback can find the target process root during native unwinding. - Preserve the existing build-id and linux-proc lookup paths first; the process-root fallback is used only when normal host lookup fails. - This fixes the behavior seen with the ImageNet Pyxis NCCL run where PyStack 1.6 reported insufficient native information or lost libtorch/libtorch_cuda/NCCL frames from container targets. Signed-off-by: Pramod Kumbhar <prkumbhar@nvidia.com>
- Resolve mapped paths through /proc/<pid>/root before libdwfl's fallback to avoid opening a different host file. - Preserve plain module paths for identical files so same-namespace module and debuginfo behavior stays unchanged. - Handle deleted and missing module names safely, and match load points against reported, main, and debug paths. Signed-off-by: Pramod Kumbhar <prkumbhar@nvidia.com>
- Build target and host-decoy libraries at one mapped path to verify native symbols use the target filesystem view. - Require the mount-namespace test in coverage CI while allowing unsupported local environments to skip it. Signed-off-by: Pramod Kumbhar <prkumbhar@nvidia.com>
- Trigger full coverage for pushes to pramodk/container-native-symbols and allow manual workflow dispatches. Signed-off-by: Pramod Kumbhar <prkumbhar@nvidia.com>
