[PATCH 3/3] TCP: htcp - use measured rtt

Change HTCP to use measured RTT rather than smooth RTT. Srtt is computed using the TCP receive timestamp options, so it is vulnerable to hostile receivers. To avoid any problems this might cause use the measured RTT instead. Signed-off-by: Stephen Hemminger <[EMAIL PROTECTED]> --- a/net/ipv4/tcp_

[PATCH 1/3] TCP: congestion control API pass RTT in microseconds

This patch changes the API for the callback that is done after an ACK is received. It solves a couple of issues: * Some congestion controls want higher resolution value of RTT (controlled by TCP_CONG_RTT_SAMPLE flag). These don't really want a ktime, but all compute a RTT in microsecond

[PATCH 2/3] TCP: cubic - eliminate use of receive time stamp

Remove use of received timestamp option value from RTT calculation in Cubic. A hostile receiver may be returning a larger timestamp option than the original value. This would cause the sender to believe the malevolent receiver had a larger RTT and because Cubic tries to provide some RTT friendlines

[PATCH 0/3] TCP timestamp hardening (update)

These patches deal with issues brought up by Gavin McCullagh about reactions of Cubic and HTCP to hostile receivers that return bogus timestamp options. If the receiver crafts a timestamp that is larger than the original, then some of the congestion control algorithms maybe come unfair. The soluti
