Nikita V. Shirokov says: ==================== In this patch series I'm adding a helper for libbpf which would allow it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and BPF_MAP_TYPE_HASH_OF_MAPS). First patch contains new helper + explains proposed workflow second patch contains tests which also could be used as example usage. v4->v5: - naming: renamed everything to map_in_map instead of mapinmap - start to return nonzero val if set_inner_map_fd failed v3->v4: - renamed helper to set_inner_map_fd - now we set this value only if it haven't been set before and only for (array|hash) of maps v2->v3: - fixing typo in patch description - initializing inner_map_fd to -1 by default v1->v2: - addressing nits - removing const identifier from fd in new helper - starting to check return val for bpf_map_update_elem ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
