christos 761bd09636 PR/30154: YAMAMOTO Takashi: tcp_close locking botch 
chgsbsize() as mentioned in the PR can be called from an interrupt context
via tcp_close(). Avoid calling uid_find() in chgsbsize().
- Instead of storing so_uid in struct socketvar, store *so_uidinfo
- Add a simple lock to struct uidinfo.

yamt 23cd288d37 ip_output: handle the case M_CSUM_TSOv4 but !IFCAP_TSOv4. 2005-04-18 22:06:28 +00:00
yamt fa67035590 add a function to handle M_CSUM_TSOv4 by software. 2005-04-18 21:55:06 +00:00
yamt e5a2b5a4a4 fix problems related to loopback interface checksum omission. PR/29971. 
- for ipv4, defer decision to ip layer as h/w checksum offloading does
  so that it can check the actual interface the packet is going to.
- for ipv6, disable it.
  (maybe will be revisited when it implements h/w checksum offloading.)

ok'ed by Jason Thorpe.

kurahone f7707899c1 Added sysctl tunable limits for the number of maximum SACK holes 
per connection and per system.

Idea taken from FreeBSD.

kurahone 0eb940bc75 TCP/SACK changes from FreeBSD. 
Ignore the SACK option if
 * The packet is not an ACK.
 * The ACK is outside of snd_una -> snd_max

yamt df05ca7085 simplify data receiver side sack processing. 
- introduce t_segqlen, the number of segments in segq/timeq.
  the name is from freebsd.
- rather than maintaining a copy of sack blocks (rcv_sack_block[]),
  build it directly from the segment list when needed.
 2005-03-16 00:39:56 +00:00
yamt 0446b7c3e3 - use full sized segments unless we actually have SACKs to send. 
- avoid TSO duplicate D-SACK.
- send SACKs regardless of TF_ACKNOW.
- don't clear rcv_sack_num when transmitting.

discussed on tech-net@.
 2005-03-16 00:38:27 +00:00
yamt 9482bc7356 don't try to use TSO to transmit a single segment. 
- there's no benefit.
- rtl8169 seems to be stuck with it.

matt 7dfa1d8cf7 Set ip_len to 0 in the wm driver when TSO is being used. 2005-03-11 17:07:51 +00:00
atatat 5b8a6c916d Revert the change that made kern.file2 and net.*.*.pcblist into nodes 
instead of structs.  It had other deleterious side-effects that are
rather nasty.  Another solution must be found.

thorpej 3901f760df In ip_fragment(): 
- Use the correct IP header length variable for other-than-first packets.
- Remove redundant setting of the original IP header length in the first
  packet's csum_data.  (It's already set before ip_fragment() is called
  in 1.147.)

atatat d945605f5b Make this build without INET6 xor INET (hah!) again. 2005-03-10 05:49:14 +00:00
atatat ca63da437a Change types of kern.file2 and net.*.*.pcblist to NODE 2005-03-10 05:43:25 +00:00
atatat 7c62c74d09 Add the following nodes to the sysctl tree: 
net.local.stream.pcblist
	net.local.dgram.pcblist
	net.inet.tcp.pcblist
	net.inet.udp.pcblist
	net.inet.raw.pcblist
	net.inet6.tcp6.pcblist
	net.inet6.udp6.pcblist
	net.inet6.raw6.pcblist

which allow retrieval of the pcbs in use for those protocols.  The
struct involved is 32/64 bit clean and incorporates parts of struct
inpcb, struct unpcb, a bit of struct tcpcb, and two socket addresses.
