Subject: [bpf PATCH 0/3] bpf, sockmap ESTABLISHED state only
Date: Mon, 17 Sep 2018 10:31:44 -0700 [thread overview]
Message-ID: <20180917172946.21218.66049.stgit@john-Precision-Tower-5810> (raw)
Eric noted that using the close callback is not sufficient
to catch all transitions from ESTABLISHED state to a LISTEN
state. So this series does two things. First, only allow
adding socks in ESTABLISH state and second use unhash callback
to catch tcp_disconnect() transitions.
Thanks,
John
