This patch adds a new sysctl option (disabled by default) which controls whether this option should be sent even with unicast NAs. The need for this arose because certain routers expect the TLLAO in some situations even as a response to unicast NS packets. Moreover, RFC 2461 recommends sending this to avoid a race condition (section 4.4, Target link-layer address) Signed-off-by: Cosmin Ratiu <cratiu@ixiacom.com> Signed-off-by: Octavian Purdila <opurdila@ixiacom.com> Signed-off-by: David S.

2009-10-07ethtool: Add reset operationBen Hutchings2-0/+55
After updating firmware stored in flash, users may wish to reset the relevant hardware and start the new firmware immediately. This should not be completely automatic as it may be disruptive. A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion.

In some cases there is not desirable to switch back to primary interface when it's link recovers and rather stay with currently active one. We need to avoid packetloss as much as we can in some cases. This is solved by introducing primary_reselect option. Note that enslaved primary slave is set as current active no matter what.

2009-10-07ipv6 sit: 6rd (IPv6 Rapid Deployment) Support.YOSHIFUJI Hideaki / 吉藤英明4-8/+159
IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly deploy IPv6 unicast service to IPv4 sites to which it provides customer premise equipment. Like 6to4, it utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 prefix of its own in place of the fixed 6to4 prefix. With this option enabled, the SIT driver offers 6rd functionality by providing additional ioctl API to configure the IPv6 Prefix for in stead of static 2002::/16 for 6to4. Original patch was done by Alexandre Cassen <acassen@freebox.fr> based on old Internet-Draft. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

2009-10-07add vif using local interface index instead of IPIlia K2-5/+20
When routing daemon wants to enable forwarding of multicast traffic it performs something like: struct vifctl vc = { .vifc_vifi = 1, .vifc_flags = 0, .vifc_threshold = 1, .vifc_rate_limit = 0, .vifc_lcl_addr = ip, /* <--- ip address of physical interface, e.g. eth0 */ .vifc_rmt_addr.s_addr = htonl(INADDR_ANY), }; setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc)); This leads (in the kernel) to calling vif_add() function call which search the (physical) device using assigned IP address: dev = ip_dev_find(net, vifc->vifc_lcl_addr.s_addr); The current API (struct vifctl) does not allow to specify an interface other way than using it's IP, and if there are more than a single interface with specified IP only the first one will be found. The attached patch (against 2.6.30.4) allows to specify an interface by its index, instead of IP address: struct vifctl vc = { .vifc_vifi = 1, .vifc_flags = VIFF_USE_IFINDEX, /* NEW */ .vifc_threshold = 1, .vifc_rate_limit = 0, .vifc_lcl_ifindex = if_nametoindex("eth0"), /* NEW */ .vifc_rmt_addr.s_addr = htonl(INADDR_ANY), }; setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc)); Signed-off-by: Ilia K. <mail4ilia@gmail.com> === modified file 'include/linux/mroute.h' Signed-off-by: David S.
