* bpf: cleanup bpf_prog_run_{save,clear}_cb helpersDaniel Borkmann2016-01-091-10/+29
| | | | | | | | | | | | Move the details behind the cb[] access into a small helper to decouple and make them generic for bpf_prog_run_save_cb()/bpf_prog_run_clear_cb() that was introduced via commit ff936a04e5f2 ("bpf: fix cb access in socket filter programs"). Also add a comment to better clarify what is done in bpf_skb_cb(). Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | We have to release the existing objects on netns removal otherwise we leak them. Chains are unregistered in first place to make sure no packets are walking on our rules and sets anymore.

These options can be used on the first socket to belong to a group before bind or on any socket in the group after bind. This change includes refactoring of the existing sk_filter code to allow reuse of the existing BPF filter validation checks.

* | | | | soreuseport: fast reuseport UDP socket selectionCraig Gallek2016-01-052-2/+3

When selecting a socket for an incoming UDP packet, use the information available in sock_reuseport if present. This required adding an additional field to the UDP source address equality function to differentiate between exact and wildcard matches. The original use case allowed wildcard matches when checking for existing port uses during bind. The new use case of adding a socket to a reuseport group requires exact address matching. Performance test (using a machine with 2 CPU sockets and a total of 48 cores): Create reuseport groups of varying size. Use one socket from this group per user thread (pinning each thread to a different core) calling recvmmsg in a tight loop. Record number of messages received per second while saturating a 10G link. 10 sockets: 18% increase (~2.8M -> 3.3M pkts/s) 20 sockets: 14% increase (~2.9M -> 3.3M pkts/s) 40 sockets: 13% increase (~3.0M -> 3.4M pkts/s) This work is based off a similar implementation written by Ying Cai <ycai@google.com> for implementing policy-based reuseport selection.

* | | | | soreuseport: define reuseport groupsCraig Gallek2016-01-052-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct sock_reuseport is an optional shared structure referenced by each socket belonging to a reuseport group. When a socket is bound to an address/port not yet in use and the reuseport flag has been set, the structure will be allocated and attached to the newly bound socket. When subsequent calls to bind are made for the same address/port, the shared structure will be updated to include the new socket and the newly bound socket will reference the group structure. Usually, when an incoming packet was destined for a reuseport group, all sockets in the same group needed to be considered before a dispatching decision was made. With this structure, an appropriate socket can be found after looking up just one socket in the group. This shared structure will also allow for more complicated decisions to be made when selecting a socket (eg a BPF filter). This work is based off a similar implementation written by Ying Cai <ycai@google.com> for implementing policy-based reuseport selection.

The ST95HF is an NFC digital transceiver with an embedded analog front-end and as such relies on the Linux NFC digital implementation. This is the 3rd user of the NFC digital stack. - ACPI support for the ST st-nci and st21nfca drivers. - A small improvement for the nfcsim driver, as we can now tune the Rx delay through sysfs. - A bunch of minor cleanups and small fixes from Christophe Ricard, for a few drivers and the NFC core code. ==================== Signed-off-by: David S.
