Revert "sit: stateless autoconf for isatap"

2009-09-27T03:28:07Z

This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by: Sascha Hlusiak Acked-by: Fred L. Templin Signed-off-by: David S. Miller

tunnel: eliminate recursion field

2009-09-24T22:39:22Z

It seems recursion field from "struct ip_tunnel" is not anymore needed. recursion prevention is done at the upper level (in dev_queue_xmit()), since we use HARD_TX_LOCK protection for tunnels. This avoids a cache line ping pong on "struct ip_tunnel" : This structure should be now mostly read on xmit and receive paths. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

sit: stateless autoconf for isatap

be sent periodically. The rs_delay can be speficied when adding the PRL entry and defaults to 15 minutes. The RS is sent from every link local adress that's assigned to the tunnel interface. It's directed to the (guessed) linklocal address of the router and is sent through the tunnel. Better: send to ff02::2 encapsuled in unicast directed to router-v4.

inet: Make tunnel RX/TX byte counters more consistent

2008-10-09T19:03:17Z

This patch makes the RX/TX byte counters for IPIP, GRE and SIT more consistent. Previously we included the external IP headers on the way out but not when the packet is inbound. The new scheme is to count payload only in both directions. For IPIP and SIT this simply means the exclusion of the external IP header. For GRE this means that we exclude the GRE header as well.

tunnels: Remove stat member from ip_tunnel struct.

All users already use on-device statistics, so this field can be safely removed. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller

[IPV6] SIT: Add PRL management for ISATAP.

2008-04-03T01:05:58Z

This patch updates the Linux the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) implementation. It places the ISATAP potential router list (PRL) in the kernel and adds three new private ioctls for PRL management. [Add several changes of structure name, constant names etc. - yoshfuji] Signed-off-by: Fred L. Templin Signed-off-by: YOSHIFUJI Hideaki

[IPV4]: Add ip_local_out

2008-01-28T22:53:47Z

Most callers of the LOCAL_OUT chain will set the IP packet length and header checksum before doing so. They also share the same output function dst_output. This patch creates a new function called ip_local_out which does all of that and converts the appropriate users over to it. Apart from removing duplicate code, it will also help in merging the IPsec output path once the same thing is done for IPv6. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPV6] net/ipv6/sit.c: make 2 functions static

[TCP/DCCP]: Introduce net_xmit_eval

2006-12-03T05:22:27Z

Throughout the TCP/DCCP (and tunnelling) code, it often happens that the return code of a transmit function needs to be tested against NET_XMIT_CN which is a value that does not indicate a strict error condition. This patch uses a macro for these recurring situations which is consistent with the already existing macro net_xmit_errno, saving on duplicated code.
