lukem 0fa231134c - replace "defopt" with "defparam" for options which must take a value,
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

itojun e2df911079 do not grab packet to joined multicast group, when ip6_dst and in6p_laddr
mismatches.  it makes the behavior more closer to 4.4BSD IPv4 code.

matt da5a70805c Convert netinet to not use the internal <sys/queue.h> field names
but instead the access macros.  Use the FOREACH macros where appropriate.

one value - 65280).

itojun e4b5b62a3d array boundary overflow on the use of IPv4 mapped address. from simonb 2001-11-02 02:37:50 +00:00
kml 77c99e8c60 Add in support for timing out IPv4 routes added due to redirects,
as discussed in tech-net several weeks ago.  It turned out that
KAME had already added this functionality to the IPv6 stack, so
I followed their example in adding the sysctl variables
net.inet.icmp.rediraccept and net.inet.icmp.redirtimeout.

thorpej e45efd967f Deprecate the "m_act" alias of "m_nextpkt" (m_act is a historical
name), and just use m_nextpkt everywhere.

IPV6_BINDV6ONLY (netbsd only) is deprecated, but still work just like before.

chs 80373b7e54 don't depend on other headers to include sys/proc.h for us. 2001-09-28 11:59:51 +00:00
thorpej d679590033 Split the pre-computed ifnet checksum flags into Tx and Rx directions.
Add capabilities bits that indicate an interface can only perform
in-bound TCPv4 or UDPv4 checksums.  There is at least one Gig-E chip
for which this is true (Level One LXT-1001), and this is also the
case for the Intel i82559 10/100 Ethernet chips.

thorpej 050e9de009 Use callouts for SYN cache timers, rather than traversing time queues
in tcp_slowtimo().

thorpej 4745c7f252 Update copyrights. 2001-09-10 22:45:46 +00:00
thorpej 6d0e813f6c Use callouts for TCP timers, rather than traversing the list of
all open TCP connections in tcp_slowtimo() (which is called 2x
per second).  It's fairly rare for TCP timers to actually fire,
so saving this list traversal is good, especially if you want
to scale to thousands of open connections.

thorpej 413e5cb878 Initialize TCP timer variables in a new function, tcp_timer_init(). 2001-09-10 20:36:43 +00:00
thorpej 3d9c42775e Add explicit initialization of TCP timer state. A noop right now. 2001-09-10 20:19:54 +00:00
thorpej 45e02f5ee8 Split tcp_timers() into multiple functions, one for each timer,
and call it directly from tcp_slowtimo() (via a table) rather
than going through tcp_userreq().

This will allow us to call TCP timers directly from callouts,
in a future revision.
2001-09-10 20:15:14 +00:00
thorpej 7446fd2bc8 Change the way receive idle time and round trip time are measured.
Instead of incrementing t_idle and t_rtt in tcp_slowtimo(), we now
take a timstamp (via tcp_now) and use subtraction to compute the
delta when we actually need it (using unsigned arithmetic so that
tcp_now wrapping is handled correctly).

Based on similar changes in FreeBSD.

thorpej c82b0994e7 Permit weaker interface matches for incoming ARP packets if the packet was
received on an interface that is part of a bridge and we find an ifaddr on
an interface that is part of the same bridge.

thorpej 35df06a642 Carve off the code that builds a TCP data packet into its own
function, and inline it, except when profiling... so we can
profile it.
2001-07-31 02:25:22 +00:00
thorpej 938720eea4 Count the number of times we "self-quench" (ip_output() returns
ENOBUFS), and don't inline tcp_segsize() if profiling.

IFF_RUNNING is clearified.  attach/detach logic is more clearner.
