If get destination options with length which is not enough for that option,getsockopt() will still return the real length of the option, which is larger then the buffer space. This is because ipv6_getsockopt_sticky() returns the real length of the option. This patch fix this problem.

If we pass NULL data buffer to getsockopt(), it will return 0, and the option length is set to -EFAULT: getsockopt(sk, IPPROTO_IPV6, IPV6_DSTOPTS, NULL, &len); This is because ipv6_getsockopt_sticky() will return -EFAULT or -EINVAL if some error occur.

The last hunk from the commit dae50295 (ipv4/ipv6 compat: Fix SSM applications on 64bit kernels.) escaped from the compat_ipv6_setsockopt to the ipv6_getsockopt (I guess due to patch smartness wrt searching for context) thus breaking 32-bit and 64-bit-without-compat compilation.

This reverts commit db1ed684 ("[IPV6] UDP: Rename IPv6 UDP files."), commit 8be8af8f ("[IPV4] UDP: Move IPv4-specific bits to other file.") and commit e898d4db ("[UDP]: Allow users to configure UDP-Lite."). First, udplite is of such small cost, and it is a core protocol just like TCP and normal UDP are. We spent enormous amounts of effort to make udplite share as much code with core UDP as possible. All of that work is less valuable if we're just going to slap a config option on udplite support. It is also causing build failures, as reported on linux-next, showing that the changeset was not tested very well. In fact, this is the second build failure resulting from the udplite change. Finally, the config options provided was a bool, instead of a modular option. Meaning the udplite code does not even get build tested by allmodconfig builds, and furthermore the user is not presented with a reasonable modular build option which is particularly needed by distribution vendors.

This patchset makes the different protocols to return an error code, so the af_inet6 module can check the initialization was correct or not.

From RFC 3493, Section 5.2: IPV6_MULTICAST_IF Set the interface to use for outgoing multicast packets. The argument is the index of the interface to use. If the interface index is specified as zero, the system selects the interface (for example, by looking up the address in a routing table and using the resulting interface). This patch adds support for (index == 0) to reset the value to it's original state, allowing the system to choose the best interface. IPv4 already behaves this way.

This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: NEric W.

This patch makes MIPv6 loadable module named "mip6". Here is a modprobe.conf(5) example to load it automatically when user application uses XFRM state for MIPv6: alias xfrm-type-10-43 mip6 alias xfrm-type-10-60 mip6 Some MIPv6 feature is not included by this modular, however, it should not be affected to other features like either IPsec or IPv6 with and without the patch. We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt separately for future work. Loadable features: * MH receiving check (to send ICMP error back) * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS) * XFRM policy/state database handling for RO These are NOT covered as loadable: * Home Address flags and its rule on source address selection * XFRM sub policy (depends on its own kernel option) * XFRM functions to receive RO as IPv6 extension header * MH sending/receiving through raw socket if user application opens it (since raw socket allows to do so) * RH2 sending as ancillary data * RH2 operation with setsockopt(2) Signed-off-by: NMasahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: NDavid S.
