Jakub Kicinski says: ==================== This series is a redo of reporting offload device information to user space after the first attempt did not take into account name spaces. As requested by Kirill offloads are now protected by an r/w sem. This allows us to remove the workqueue and free the offload state fully when device is removed (suggested by Alexei). Net namespace is reported with a device/inode pair. The accompanying bpftool support is placed in common code because maps will have very similar info. Note that the UAPI information can't be nicely encapsulated into a struct, because in case we need to grow the device information the new fields will have to be added at the end of struct bpf_prog_info, we can't grow structures in the middle of bpf_prog_info. v3: - use dev_get_by_index(); - redo ns code (new patch 6). v2: - rework the locking in patch 1 (use RCU instead of locking dependencies); - grab RTNL for a short time in patch 6; - minor update to the test in patch 8. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
