2017-08-14	tcp: ulp: avoid module refcnt leak in tcp_set_ulp	Sabrina Dubroca
	__tcp_ulp_find_autoload returns tcp_ulp_ops after taking a reference on the module. Then, if ->init fails, tcp_set_ulp propagates the error but nothing releases that reference.

2017-06-23	tcp: fix out-of-bounds access in ULP sysctl	Jakub Kicinski
	KASAN reports out-of-bound access in proc_dostring() coming from proc_tcp_available_ulp() because in case TCP ULP list is empty the buffer allocated for the response will not have anything printed into it. Set the first byte to zero to avoid strlen() going out-of-bounds. Fixes: 734942cc4ea6 ("tcp: ULP infrastructure") Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2017-06-15	tcp: ULP infrastructure	Dave Watson
	Add the infrustructure for attaching Upper Layer Protocols (ULPs) over TCP sockets. Based on a similar infrastructure in tcp_cong. The idea is that any ULP can add its own logic by changing the TCP proto_ops structure to its own methods. Example usage: setsockopt(sock, SOL_TCP, TCP_ULP, "tls", sizeof("tls")); modules will call: tcp_register_ulp(&tcp_tls_ulp_ops); to register/unregister their ulp, with an init function and name. A list of registered ulps will be returned by tcp_get_available_ulp, which is hooked up to /proc. Example: $ cat /proc/sys/net/ipv4/tcp_available_ulp tls There is currently no functionality to remove or chain ULPs, but it should be possible to add these in the future if needed.
