John Fastabend says: ==================== sockmap fixes for net The following implements a set of fixes for sockmap and changes the API slightly in a few places to reduce preempt_disable/enable scope. We do this here in net because it requires an API change and this avoids getting stuck with legacy API going forward. The short description: Access to skb mark is removed, it is problematic when we add features in the future because mark is a union and used by the TCP/socket code internally. We don't want to expose this to the BPF programs or let programs change the values. The other change is caching metadata in the skb itself between when the BPF program returns a redirect code and the core code implements the redirect. This avoids having per cpu metadata. Finally, tighten restriction on using sockmap to CAP_NET_ADMIN and only SOCK_STREAM sockets. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

README
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.
