Feature #1361: Add support for socket options TCP_KEEPCNT, TCP_KEEPIDLE, TCP_KEEPINTVL
1361 missed two codepaths
The changes for bug 1361 missed two codepaths (and this code reviewer takes full responsibility for missing them during review).
1.) The tcp_reinit_values() function needs to mention every field in tcp_t, according to the header file. It actually doesn't, but our new fields should be mentioned in there.
2.) tcp_init_values() has a (parent != NULL) case (i.e. sockets created by accept(3xn)) which doesn't copy over the new values.
