2020-02-28	net: datagram: drop 'destructor' argument from several helpers	Paolo Abeni	1	-1/+1
	The only users for such argument are the UDP protocol and the UNIX socket family. We can safely reclaim the accounted memory directly from the UDP code and, after the previous patch, we can do scm stats accounting outside the datagram helpers. Overall this cleans up a bit some datagram-related helpers, and avoids an indirect call per packet in the UDP receive path. v1 -> v2: - call scm_stat_del() only when not peeking - Kirill - fix build issue with CONFIG_INET_ESPINTCP Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Kirill Tkhai <ktkhai@virtuozzo.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2019-12-09	xfrm: add espintcp (RFC 8229)	Sabrina Dubroca	1	-0/+509
	TCP encapsulation of IKE and IPsec messages (RFC 8229) is implemented as a TCP ULP, overriding in particular the sendmsg and recvmsg operations. A Stream Parser is used to extract messages out of the TCP stream using the first 2 bytes as length marker. Received IKE messages are put on "ike_queue", waiting to be dequeued by the custom recvmsg implementation. Received ESP messages are sent to XFRM, like with UDP encapsulation. Some of this code is taken from the original submission by Herbert Xu. Currently, only IPv4 is supported, like for UDP encapsulation.
