These definitions are essential for applications to set\nsocket options and protocol identifiers related to the QUIC protocol.\n\nQUIC does not possess a protocol number allocated from IANA, and like\nIPPROTO_MPTCP, IPPROTO_QUIC is merely a value used when opening a QUIC\nsocket with:\n\n socket(AF_INET, SOCK_STREAM, IPPROTO_QUIC);\n\nNote we did not opt for UDP ULP for QUIC implementation due to several\nconsiderations:\n\n- QUIC's connection Migration requires at least 2 UDP sockets for one\n QUIC connection at the same time, not to mention the multipath\n feature in one of its draft RFCs.\n\n- In-Kernel QUIC, as a Transport Protocol, wants to provide users with\n the TCP or SCTP like Socket APIs, like connect()/listen()/accept()...\n Note that a single UDP socket might even be used for multiple QUIC\n connections.\n\nThe use of IPPROTO_QUIC type sockets over UDP tunnel will effectively\naddress these challenges and provides a more flexible and scalable\nsolution.\n\nSigned-off-by: Xin Long \nAcked-by: Paolo Abeni \n---\nv11:\n - Set maximum line length to 80 characters.\n---\n include/linux/socket.h | 1 +\n include/uapi/linux/in.h | 2 ++\n 2 files changed, 3 insertions(+)","diff":"diff --git a/include/linux/socket.h b/include/linux/socket.h\nindex ec4a0a025793..9b6c3cd766ca 100644\n--- a/include/linux/socket.h\n+++ b/include/linux/socket.h\n@@ -401,6 +401,7 @@ struct ucred {\n #define SOL_MCTP\t285\n #define SOL_SMC\t\t286\n #define SOL_VSOCK\t287\n+#define SOL_QUIC\t288\n \n /* IPX options */\n #define IPX_TYPE\t1\ndiff --git a/include/uapi/linux/in.h b/include/uapi/linux/in.h\nindex ced0fc3c3aa5..e4072152f2e6 100644\n--- a/include/uapi/linux/in.h\n+++ b/include/uapi/linux/in.h\n@@ -85,6 +85,8 @@ enum {\n #define IPPROTO_RAW\t\tIPPROTO_RAW\n IPPROTO_SMC = 256,\t\t/* Shared Memory Communications\t\t*/\n #define IPPROTO_SMC\t\tIPPROTO_SMC\n+ IPPROTO_QUIC = 261,\t\t/* A UDP-Based Multiplexed Secure Transport */\n+#define IPPROTO_QUIC\t\tIPPROTO_QUIC\n IPPROTO_MPTCP = 262,\t\t/* Multipath TCP connection\t\t*/\n #define IPPROTO_MPTCP\t\tIPPROTO_MPTCP\n IPPROTO_MAX\n","prefixes":["net-next","v11","01/15"]}
