This is the ninth report for TCP UTO. * Short TCP UTO description UTO stands for User Timeout Option (it is described in RFC5482). TCP UTO specifies a peer should be allowed to advertise its chosen `User Timeout' for a connection. The wiki page for this project: http://wiki.freebsd.org/CatalinNicutar/TCPUTO * Work completed last weeks * I have tested IPv6 and added 3 new tests in tools/regression * I have added a new capture file on the wiki page (a scenario where the server imposes a very small timeout) * I have started stressing the TCP stack with a tool that opens many connections and doesn't ACK data (tying server resources) * My goals for this week * I will try to address the security problems of large UTO values ( cases when server resources are tied by misbehaving clients) * I am considering adding support to varnishd and ftpd If you have questions, suggestions or advices drop me an email to cnicutar@FreeBSD.org.
