Lorenz Bauer says: ==================== This series adds the necessary helpers to determine wheter a given (encapsulated) TCP packet belongs to a connection known to the network stack. * bpf_skc_lookup_tcp gives access to request and timewait sockets * bpf_tcp_check_syncookie identifies the final 3WHS ACK when syncookies are enabled The goal is to be able to implement load-balancing approaches like glb-director [1] or Beamer [2] in pure eBPF. Specifically, we'd like to replace the functionality of the glb-redirect kernel module [3] by an XDP program or tc classifier. Changes in v3: * Fix missing check for ip4->ihl * Only cast to unsigned long in BPF_CALLs Changes in v2: * Rename bpf_sk_check_syncookie to bpf_tcp_check_syncookie. * Add bpf_skc_lookup_tcp. Without it bpf_tcp_check_syncookie doesn't make sense. * Check tcp_synq_no_recent_overflow() in bpf_tcp_check_syncookie. * Check th->syn in bpf_tcp_check_syncookie. * Require CONFIG_IPV6 to be a built in. 1: https://github.com/github/glb-director 2: https://www.usenix.org/conference/nsdi18/presentation/olteanu 3: https://github.com/github/glb-director/tree/master/src/glb-redirect ==================== 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.
