Hi All, I am not sure if anybody has asked it before. I could not find answer by doing rough search on Internet, if it is duplicate question, sorry in advance.
My question is that, for getting socket options in tcp_ctloutput() in tcp_usrreq.c, why do we need to do lock with INP_WLOCK(inp) as setting socket options does. Why do we just use INP_RLOCK(inp), as it looks not changing anything in tcp control block? Thank you for your kindly answer.
