* net: Remove __KERNEL__ cpp checks from include/netDavid S. Miller2011-04-241-6/+0
| | | | | | | | | | | These header files are never installed to user consumption, so any __KERNEL__ cpp checks are superfluous. Projects should also not copy these files into their userland utility sources and try to use them there. If they insist on doing so, the onus is on them to sanitize the headers as needed.

| | | | | | | | | | | | | | | | | | | | | It's unused. It isn't needed -- read or write flag is already passed and sysctl shouldn't care about the rest.

* ipv6: Fix sporadic sendmsg -EINVAL when sending to multicast groups.David S. Miller2009-01-041-2/+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.

* [IPv6]: Export userland ND options through netlink (RDNSS support)Pierre Ynard2007-10-101-0/+1
| | | | | | | | | | | | | | | | | As discussed before, this patch provides userland with a way to access relevant options in Router Advertisements, after they are processed and validated by the kernel. Extra options are processed in a generic way; this patch only exports RDNSS options described in RFC5006, but support to control which options are exported could be easily added. A new rtnetlink message type is defined, to transport Neighbor Discovery options, along with optional context information. At the moment only the address of the router sending an RDNSS option is included, but additional attributes may be later defined, if needed by new use cases.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+135
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!
