Hi, all:
In function tcp_timewait(), which will be called when receiving a
segment as current TCP state at TIME_WAIT. However, in the body of the
function definition, it simply goes to "drop" before generating RST or
RST/ACK towards the unicast source. Is the behavior correct because the
followed codes (from line 2228 to line 3261) would never be reached!
Yes, this code was never used. After the 'goto drop;' there used
to be a 'reset:' label. However it was never used and got lost
in rev. 1.254 because of compiler warnings. The code is related
to the comment earlier in the function: "NOTE: for FIN_WAIT_2 (to
be added later), must validate sequence number before accepting RST".
I agree that is very confusing and I shall put an appropriate comment
next to it.
