lukem c80b4400e5 add the following, derived from FreeBSD: 
* IP_PORTRANGE socket option, which controls how the ephemeral ports
  are allocated. it takes the following settings:
	IP_PORTRANGE_DEFAULT	use anonportmin (49152) -> anonportmax (65535)
	IP_PORTRANGE_HIGH	as IP_PORTRANGE_DEFAULT (retained for FreeBSD
				compat reasons, where these are separate)
	IP_PORTRANGE_LOW	use 600 -> 1023. only works if uid==0.
* in_pcb flag INP_ANONPORT. set if port was allocated ephmerally

matt 8c42ff649b Add support for returning maximum supported MTU when ip_output fails with 
EMSGSIZE.

thorpej de572198ad Implement in_pcbrtentry() - return the route associated with a PCB. If 
one does not exist, attempt to allocate one.  This is mostly pulled from
tcp_input.c.

thorpej efa8881dbe Pull SYN_cache_branch down into the main line. 1997-07-23 21:26:40 +00:00
thorpej 9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

mycroft d6121891ef Overlay inp_faddr and inp_laddr into the header prototype. 1996-09-17 17:10:20 +00:00
mycroft 9bfa240a98 Hash unconnected PCBs. 1996-09-15 18:11:06 +00:00
mycroft 62a6cce9ca Add in_nullhost() and in_hosteq() macros, to hide some protocol 
details.  Also, fix a bug in TCP wrt SYN+URG packets.

mycroft 49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and 
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.

mycroft 67e78477db Build a hash table of PCBs. Hash function needs tweaking. 1996-01-31 03:49:23 +00:00
cgd f90cf78fba convert pcb lists to CIRCLEQs, so that the end can be looked at more 
easily, and so that the original (insque/remque) logic can be effectively
mimiced.  (This fixes a bug in the previous set of list changes.)
also (since terminator is no longer null) reinstate uninitted list checks,
but mark them XXX.

mycroft cd7edee1ca in_pcbnotify*() don't return anything. 1995-06-12 06:49:55 +00:00
mycroft 6897f39ae9 Various cleanup, including: 
* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.

These patches are derived from the IP Multicast patches for BSDI.
