* ipv6: add support for NETDEV_RESEND_IGMP eventVlad Yasevich2017-03-291-0/+2

* net: add confirm_neigh method to dst_opsJulian Anastasov2017-02-071-0/+17
| | | | | | | | | | | | | | Add confirm_neigh method to dst_ops and use it from IPv4 and IPv6 to lookup and confirm the neighbour. Its usage via the new helper dst_confirm_neigh() should be restricted to MSG_PROBE users for performance reasons. For XFRM prefer the last tunnel address, if present. With help from Steffen Klassert.

* ipv6 addrconf: Implemented enhanced DAD (RFC7527)Erik Nordmark2016-12-041-1/+4
| | | | | | | | | | | | | | | Implemented RFC7527 Enhanced DAD. IPv6 duplicate address detection can fail if there is some temporary loopback of Ethernet frames. RFC7527 solves this by including a random nonce in the NS messages used for DAD, and if an NS is received with the same nonce it is assumed to be a looped back DAD probe and is ignored. RFC7527 is enabled by default. Can be disabled by setting both of conf/{all,interface}/enhanced_dad to zero.

* ipv6: introduce neighbour discovery opsAlexander Aring2016-06-161-3/+194
| | | | | | | | | | | | | | | | | | This patch introduces neighbour discovery ops callback structure. The idea is to separate the handling for 6LoWPAN into the 6lowpan module.

* Revert "ipv6: ndisc: inherit metadata dst when creating ndisc requests"Nicolas Dichtel2015-12-011-2/+1
| | | | | | | | | | | | | | | | This reverts commit ab450605b35caa768ca33e86db9403229bf42be4. In IPv6, we cannot inherit the dst of the original dst. ndisc packets are IPv6 packets and may take another route than the original packet. This patch breaks the following scenario: a packet comes from eth0 and is forwarded through vxlan1. The encapsulated packet triggers an NS which cannot be sent because of the wrong route.

* neigh: Factor out ___neigh_lookup_norefEric W. Biederman2015-03-041-18/+1
| | | | | | | | | | | | | | | | | | | | | | | | | While looking at the mpls code I found myself writing yet another version of neigh_lookup_noref. We currently have __ipv4_lookup_noref and __ipv6_lookup_noref. So to make my work a little easier and to make it a smidge easier to verify/maintain the mpls code in the future I stopped and wrote ___neigh_lookup_noref. Then I rewote __ipv4_lookup_noref and __ipv6_lookup_noref in terms of this new function. I tested my new version by verifying that the same code is generated in ip_finish_output2 and ip6_finish_output2 where these functions are inlined. To get to ___neigh_lookup_noref I added a new neighbour cache table function key_eq. So that the static size of the key would be available. I also added __neigh_lookup_noref for people who want to to lookup a neighbour table entry quickly but don't know which neibhgour table they are going to look up. Signed-off-by: "Eric W.

* ipv6: don't call fib6_run_gc() until routing is readyMichal Kubeček2013-09-111-0/+2
| | | | | | | | | | | | | | | | | When loading the ipv6 module, ndisc_init() is called before ip6_route_init(). As the former registers a handler calling fib6_run_gc(), this opens a window to run the garbage collector before necessary data structures are initialized. If a network device is initialized in this window, adding MAC address to it triggers a NETDEV_CHANGEADDR event, leading to a crash in fib6_clean_all(). Take the event handler registration out of ndisc_init() into a separate function ndisc_late_init() and move it after ip6_route_init().

| | | | | | | | | | | | | | | | | Eric noticed, that when there will be devices with equal indices, some hash functions that use them will become less effective as they could. Fix this in advance by mixing the net_device address into the hash value instead of the device index. This is true for arp and ndisc hash fns. The netlabel, can and llc ones are also ifindex-based, but that three are init_net-only, thus will not be affected. Many thanks to David and Eric for the hash32_ptr implementation!

* ipv6: Fix sporadic sendmsg -EINVAL when sending to multicast groups.David S. Miller2009-01-051-2/+2
| | | | | | | | | | | | | | | | | | | | Thanks to excellent diagnosis by Eduard Guzovsky. The core problem is that on a network with lots of active multicast traffic, the neighbour cache can fill up. If we try to allocate a new route and thus neighbour cache entry, the bog-standard GC attempt the neighbour layer does in ineffective because route entries hold a reference to the existing neighbour entries and GC can only liberate entries with no references. IPV4 already has a way to handle this, by doing a route cache GC in such situations (when neigh attach returns -ENOBUFS). So simply mimick this on the ipv6 side.

* bonding: send IPv6 neighbor advertisement on failoverBrian Haley2008-11-061-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds better IPv6 failover support for bonding devices, especially when in active-backup mode and there are only IPv6 addresses configured, as reported by Alex Sidorenko. - Creates a new file, net/drivers/bonding/bond_ipv6.c, for the IPv6-specific routines. Both regular bonds and VLANs over bonds are supported. - Adds a new tunable, num_unsol_na, to limit the number of unsolicited IPv6 Neighbor Advertisements that are sent on a failover event. Default is 1. - Creates two new IPv6 neighbor discovery functions: ndisc_build_skb() ndisc_send_skb() These were required to support VLANs since we have to be able to add the VLAN id to the skb since ndisc_send_na() and friends shouldn't be asked to do this. These two routines are basically __ndisc_send() split into two pieces, in a slightly different order. - Updates Documentation/networking/bonding.txt and bumps the rev of bond support to 3.4.0. On failover, this new code will generate one packet: - An unsolicited IPv6 Neighbor Advertisement, which helps the switch learn that the address has moved to the new slave. Testing has shown that sending just the NA results in pretty good behavior when in active-back mode, I saw no lost ping packets for example.

* [INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.hArnaldo Carvalho de Melo2006-01-031-4/+13
| | | | | | | | | | | To help in reducing the number of include dependencies, several files were touched as they were getting needed headers indirectly for stuff they use. Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had linux/dccp.h include twice. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

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!
