This removes a redundancy in the CCID half-connection (hc) naming scheme: * instead of 'hctx->tx_...', write 'hc->tx_...'; * instead of 'hcrx->rx_...', write 'hc->rx_...'; which works because the 'type' of the half-connection is encoded in the 'rx_' / 'tx_' prefixes.

This patch starts a less problematic naming convention for CCID structs. The old naming convention used 'hc{tx,rx}->ccid?hc{tx,rx}->...' as recurring prefixes, which made the code * hard to write (not easy to fit into 80 characters); * hard to read (most of the space is occupied by prefixes). The new naming scheme: * struct entries for the TX socket are prefixed by 'tx_'; * and those for the RX socket are prefixed by 'rx_'. The identifiers then remain distinguishable when grep-ing through the tree: (a) RX/TX sockets are distinguished by the naming scheme, (b) individual CCIDs are distinguished by filename (ccid{2,3,4}.{c,h}). This first patch implements the scheme for CCID-2. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk> Acked-by: NArnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: NDavid S.

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: NCosmin Ratiu <cratiu@ixiacom.com> Signed-off-by: NOctavian Purdila <opurdila@ixiacom.com> Signed-off-by: NDavid S.

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.

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.

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: NIlia K. <mail4ilia@gmail.com> === modified file 'include/linux/mroute.h' Signed-off-by: NDavid S.
