Date: Fri, 24 Sep 2010 20:05:57 -0700 (PDT) [thread overview]
Message-ID: <20100924.200557.229751150.davem@davemloft.net> (raw)
In-Reply-To: <20100922020212.d2aaec57.akpm@linux-foundation.org>
tcp_syn_retries is not an exact calculation.
It is input into a calculation which estimates how long that many
retransmits (with suitable backoff applied) will take, and that time
estimte in turn determines the time limit for when we'll kill the
connection attempt.
Feel free to update the documentation in
Documentation/networking/ip-sysctl.txt to more closely match the
behavior.
The logic is in net/ipv4/tcp_timer.c:retransmits_timed_out().
