* Revert "sit: stateless autoconf for isatap"Sascha Hlusiak2009-09-261-1/+1
| | | | | | | | | | | | | | | 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 <contact@saschahlusiak.de> Acked-by: Fred L. Templin <Fred.L.Templin@boeing.com> Signed-off-by: David S.

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. Signed-off-by: Sascha Hlusiak <contact@saschahlusiak.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: replace __constant_{endian} uses in net headersHarvey Harrison2009-02-141-8/+8
| | | | | | | | Base versions handle constant folding now. For headers exposed to userspace, we must only expose the __ prefixed versions. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Fix userland breakage wrt. linux/if_tunnel.hDavid S. Miller2009-02-021-0/+3
| | | | | | | | | | | | | | | | | Reported by Andrew Walrond <andrew@walrond.org> Changeset c19e654ddbe3831252f61e76a74d661e1a755530 ("gre: Add netlink interface") added an include of linux/ip.h to linux/if_tunnel.h We can't really let that get exposed to userspace because this conflicts with types defined in netinet/ip.h which userland is almost certainly going to have included either explicitly or implicitly. So guard this include with a __KERNEL__ ifdef. Signed-off-by: David S. Miller <davem@davemloft.net>
* gre: Add netlink interfaceHerbert Xu2008-10-091-0/+19
| | | | | | | | | | | | | This patch adds a netlink interface that will eventually displace the existing ioctl interface. It utilises the elegant rtnl_link_ops mechanism. This also means that user-space no longer needs to rely on the tunnel interface being of type GRE to identify GRE tunnels. The identification can now occur using rtnl_link_ops.

* ipv6 sit: Avoid extra need for compat layer in PRL management.YOSHIFUJI Hideaki2008-06-161-1/+1
| | | | | | | | | | | We've introduced extra need of compat layer for ip_tunnel_prl{} for PRL (Potential Router List) management. Though compat_ioctl is still missing in ipv4/ipv6, let's make the interface more straight-forward and eliminate extra need for nasty compat layer anyway since the interface is new for 2.6.26.

* [IPV6] SIT: Add PRL management for ISATAP.Templin, Fred L2008-04-031-3/+15
| | | | | | | | | | | | 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.

* [IPV6]: Add RFC4214 supportFred L. Templin2008-01-281-0/+3
| | | | | | | | | | | | | | | | | | This patch includes support for the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) per RFC4214. It uses the SIT module, and is configured using extensions to the "iproute2" utility. The diffs are specific to the Linux 2.6.24-rc2 kernel distribution. This version includes the diff for ./include/linux/if.h which was missing in the v2.4 submission and is needed to make the patch compile. The patch has been installed, compiled and tested in a clean 2.6.24-rc2 kernel build area. Signed-off-by: Fred L.

* [IP] TUNNEL: Fix to be built with user application.Masahide NAKAMURA2007-01-231-0/+2
| | | | | | | | | | | | | include/linux/if_tunnel.h is broken for user application because it was changed to use __be32 which is required to include linux/types.h in advance but didn't. (This issue is found when building MIPL2 daemon. We are not sure this is the last header to be fixed about __be32.)

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
