Martin KaFai Lau says: ==================== The bpf_prog can store specific info to a sk by using bpf_sk_storage. In other words, a sk can be extended by a bpf_prog. This series is to support providing bpf_sk_storage data during inet_diag's dump. The primary target is the usage like iproute2's "ss". The first two patches are refactoring works in inet_diag to make adding bpf_sk_storage support easier. The next two patches do the actual work. Please see individual patch for details. v2: - Add commit message for u16 to u32 change in min_dump_alloc in Patch 4 (Song) - Add comment to explain the !skb->len check in __inet_diag_dump in Patch 4. - Do the map->map_type check earlier in Patch 3 for readability. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
