* Much delayed but now present: RFC 1948 style sequence numberssilby2001-08-221-21/+0
| | | | | | | | | | In order to ensure security and functionality, RFC 1948 style initial sequence number generation has been implemented. Barring any major crypographic breakthroughs, this algorithm should be unbreakable. In addition, the problems with TIME_WAIT recycling which affect our currently used algorithm are not present.

| | | | | | | | | | | | | | | | | | generation scheme. Users may now select between the currently used OpenBSD algorithm and the older random positive increment method. While the OpenBSD algorithm is more secure, it also breaks TIME_WAIT handling; this is causing trouble for an increasing number of folks. To switch between generation schemes, one sets the sysctl net.inet.tcp.tcp_seq_genscheme. 0 = random positive increments, 1 = the OpenBSD algorithm. 1 is still the default. Once a secure _and_ compatible algorithm is implemented, this sysctl will be removed. Reviewed by: jlemon Tested by: numerous subscribers of -net

* Restructure TCP timeout handling:jlemon1999-08-301-1/+1
| | | | | | | | | | - eliminate the fast/slow timeout lists for TCP and instead use a callout entry for each timer. - increase the TCP timer granularity to HZ - implement "bad retransmit" recovery, as presented in "On Estimating End-to-End Network Path Properties", by Allman and Paxson.
