* net: replace dst_cache ip6_tunnel implementation with the generic onePaolo Abeni2016-02-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This also fix a potential race into the existing tunnel code, which could lead to the wrong dst to be permanenty cached: CPU1: CPU2: <xmit on ip6_tunnel> <cache lookup fails> dst = ip6_route_output(...) <tunnel params are changed via nl> dst_cache_reset() // no effect, // the cache is empty dst_cache_set() // the wrong dst // is permanenty stored // into the cache With the new dst implementation the above race is not possible since the first cache lookup after dst_cache_reset will fail due to the timestamp check Signed-off-by: Paolo Abeni <pabeni@redhat.com> Suggested-and-acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

* ipv4+ipv6: Make INET*_ESP select CRYPTO_ECHAINIVThomas Egerer2016-01-251-0/+1
| | | | | | | | | | | | | | | The ESP algorithms using CBC mode require echainiv. Hence INET*_ESP have to select CRYPTO_ECHAINIV in order to work properly. This solves the issues caused by a misconfiguration as described in [1]. The original approach, patching crypto/Kconfig was turned down by Herbert Xu [2].

* net: Identifier Locator Addressing moduleTom Herbert2015-08-171-0/+19
| | | | | | | | | | | | | | | | | Adding new module name ila. This implements ILA translation. Light weight tunnel redirection is used to perform the translation in the data path. This is configured by the "ip -6 route" command using the "encap ila <locator>" option, where <locator> is the value to set in destination locator of the packet. e.g. ip -6 route add 3333:0:0:1:5555:0:1:0/128 \ encap ila 2001:0:0:1 via 2401:db00:20:911a:face:0:25:0 Sets a route where 3333:0:0:1 will be overwritten by 2001:0:0:1 on output.

* net: Build IPv6 into kernel by defaultTom Herbert2015-07-131-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the default to build IPv6 into the kernel. IPv6 now has significant traction and any remaining vestiges of IPv6 not being provided parity with IPv4 should be swept away. IPv6 is now core to the Internet and kernel. Points on IPv6 adoption: - Per Google statistics, IPv6 usage has reached 7% on the Internet and continues to exhibit an exponential growth rate https://www.google.com/intl/en/ipv6/statistics.html - Just a few days ago ARIN officially depleted its IPv4 pool - IPv6 only data centers are being successfully built (e.g. at Facebook) This patch changes the IPv6 Kconfig for IPV6. Default for CONFIG_IPV6 is set to "y" and the text has been updated to reflect the maturity of IPv6. Impact: Under some circumstances building modules in to kernel might have a performance advantage. In my testing, I did notice a very slight improvement. This will obviously increase the size of the kernel image. In my configuration I see: IPv6 as module: text data bss dec hex filename 9703666 1899288 933888 12536842 bf4c0a vmlinux IPv6 built into kernel text data bss dec hex filename 9436490 1879600 913408 12229498 ba9b7a vmlinux Which increases text size by ~270K (2.8% increase in size for me). If image size is an issue, presumably for a device which does not do IP networking (IMO we should be discouraging IPv4-only devices), IPV6 can be disabled or still built as a module.

* ipv6: ip6mr: support multiple tablesPatrick McHardy2010-05-111-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net>

| | | | | | | | | | | | | | | | | | | | 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.

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: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | Nominally an autoconfigured IPv6 address is added to an interface in the Tentative state (as per RFC 2462). Addresses in this state remain in this state while the Duplicate Address Detection process operates on them to determine their uniqueness on the network. During this period, these tentative addresses may not be used for communication, increasing the time before a node may be able to communicate on a network. Using Optimistic Duplicate Address Detection, autoconfigured addresses may be used immediately for communication on the network, as long as certain rules are followed to avoid conflicts with other nodes during the Duplicate Address Detection process.

* [INET]: Introduce tunnel4/tunnel6Herbert Xu2006-03-281-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically this patch moves the generic tunnel protocol stuff out of xfrm4_tunnel/xfrm6_tunnel and moves it into the new files of tunnel4.c and tunnel6 respectively. The reason for this is that the problem that Hugo uncovered is only the tip of the iceberg. The real problem is that when we removed the dependency of ipip on xfrm4_tunnel we didn't really consider the module case at all. For instance, as it is it's possible to build both ipip and xfrm4_tunnel as modules and if the latter is loaded then ipip simply won't load. After considering the alternatives I've decided that the best way out of this is to restore the dependency of ipip on the non-xfrm-specific part of xfrm4_tunnel. This is acceptable IMHO because the intention of the removal was really to be able to use ipip without the xfrm subsystem. This is still preserved by this patch. So now both ipip/xfrm4_tunnel depend on the new tunnel4.c which handles the arbitration between the two. The order of processing is determined by a simple integer which ensures that ipip gets processed before xfrm4_tunnel. The situation for ICMP handling is a little bit more complicated since we may not have enough information to determine who it's for. It's not a big deal at the moment since the xfrm ICMP handlers are basically no-ops. In future we can deal with this when we look at ICMP caching in general. The user-visible change to this is the removal of the TUNNEL Kconfig prompts. This makes sense because it can only be used through IPCOMP as it stands. The addition of the new modules shouldn't introduce any problems since module dependency will cause them to be loaded. Oh and I also turned some unnecessary pskb's in IPv6 related to this patch to skb's. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
