From edefba66d929eb2d023df93a0a8175a4ffe82684 Mon Sep 17 00:00:00 2001 From: Jason Xing Date: Fri, 2 Aug 2024 18:21:09 +0800 Subject: tcp: rstreason: introduce SK_RST_REASON_TCP_STATE for active reset Introducing a new type TCP_STATE to handle some reset conditions appearing in RFC 793 due to its socket state. Actually, we can look into RFC 9293 which has no discrepancy about this part. Signed-off-by: Jason Xing Reviewed-by: Eric Dumazet Signed-off-by: David S.
