Linux-2.6.12-rc2 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.

ipv6: updates to privacy addresses per RFC 4941. Update the code to handle some of the differences between RFC 3041 and RFC 4941, which obsoletes it. Also a couple of janitorial fixes. - Allow router advertisements to increase the lifetime of temporary addresses. This was not allowed by RFC 3041, but is specified by RFC 4941. It is useful when RA lifetimes are lower than TEMP_{VALID,PREFERRED}_LIFETIME: in this case, the previous code would delete or deprecate addresses prematurely. - Change the default of MAX_RETRY to 3 per RFC 4941. - Add a comment to clarify that the preferred and valid lifetimes in inet6_ifaddr are relative to the timestamp. - Shorten lines to 80 characters in a couple of places.

ipv4: introduce address lifetime There are some usecase when lifetime of ipv4 addresses might be helpful. For example: 1) initramfs networkmanager uses a DHCP daemon to learn network configuration parameters 2) initramfs networkmanager addresses, routes and DNS configuration 3) initramfs networkmanager is requested to stop 4) initramfs networkmanager stops all daemons including dhclient 5) there are addresses and routes configured but no daemon running. If the system doesn't start networkmanager for some reason, addresses and routes will be used forever, which violates RFC 2131. This patch is essentially a backport of ivp6 address lifetime mechanism for ipv4 addresses. Current "ip" tool supports this without any patch (since it does not distinguish between ipv4 and ipv6 addresses in this perspective. Also, this should be back-compatible with all current netlink users. Reported-by: Pavel Šimerda <psimerda@redhat.com> Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S.

[IPV6]: Add RFC4214 support This patch includes support for the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) per RFC4214. It uses the SIT module, and is configured using extensions to the "iproute2" utility. The diffs are specific to the Linux 2.6.24-rc2 kernel distribution. This version includes the diff for ./include/linux/if.h which was missing in the v2.4 submission and is needed to make the patch compile. The patch has been installed, compiled and tested in a clean 2.6.24-rc2 kernel build area. Signed-off-by: Fred L.

ipv6: add ipv6_addr_hash() helper Introduce ipv6_addr_hash() helper doing a XOR on all bits of an IPv6 address, with an optimized x86_64 version. Use it in flow dissector, as suggested by Andrew McGregor, to reduce hash collision probabilities in fq_codel (and other users of flow dissector) Use it in ip6_tunnel.c and use more bit shuffling, as suggested by David Laight, as existing hash was ignoring most of them. Use it in sunrpc and use more bit shuffling, using hash_32(). Use it in net/ipv6/addrconf.c, using hash_32() as well. As a cleanup, use it in net/ipv4/tcp_metrics.c Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Andrew McGregor <andrewmcgr@gmail.com> Cc: Dave Taht <dave.taht@gmail.com> Cc: Tom Herbert <therbert@google.com> Cc: David Laight <David.Laight@ACULAB.COM> Cc: Joe Perches <joe@perches.com> Signed-off-by: David S.

netfilter: add nf_ipv6_ops hook to fix xt_addrtype with IPv6 Quoting https://bugzilla.netfilter.org/show_bug.cgi?id=812: [ ip6tables -m addrtype ] When I tried to use in the nat/PREROUTING it messes up the routing cache even if the rule didn't matched at all. [..] If I remove the --limit-iface-in from the non-working scenario, so just use the -m addrtype --dst-type LOCAL it works! This happens when LOCAL type matching is requested with --limit-iface-in, and the default ipv6 route is via the interface the packet we test arrived on. Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation creates an unwanted cached entry, and the packet won't make it to the real/expected destination. Silently ignoring --limit-iface-in makes the routing work but it breaks rule matching (--dst-type LOCAL with limit-iface-in is supposed to only match if the dst address is configured on the incoming interface; without --limit-iface-in it will match if the address is reachable via lo). The test should call ipv6_chk_addr() instead. However, this would add a link-time dependency on ipv6. There are two possible solutions: 1) Revert the commit that moved ipt_addrtype to xt_addrtype, and put ipv6 specific code into ip6t_addrtype. 2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions. While the former might seem preferable, Pablo pointed out that there are more xt modules with link-time dependeny issues regarding ipv6, so lets go for 2).

[IPV6] MIP6: Loadable module support for MIPv6. 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: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

[IPV6] ADDRCONF: Optimistic Duplicate Address Detection (RFC 4429) Support. 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.

In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.

bonding: remap muticast addresses without using dev_close() and dev_open() This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.

ipv6: Check RA for sllao when configuring optimistic ipv6 address (v2) Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop route for the interface we're adding an addres to was wrong (see commit 7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069). for one, it never triggers, and two, it was completely wrong to begin with. This test was meant to cover this section of RFC 4429: 3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration * (modifies section 5.5) A host MAY choose to configure a new address as an Optimistic Address. A host that does not know the SLLAO of its router SHOULD NOT configure a new address as Optimistic. A router SHOULD NOT configure an Optimistic Address. This patch should bring us into proper compliance with the above clause. Since we only add a SLAAC address after we've received a RA which may or may not contain a source link layer address option, we can pass a pointer to that option to addrconf_prefix_rcv (which may be null if the option is not present), and only set the optimistic flag if the option was found in the RA. Change notes: (v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than a pointer to make its use more clear as per request from davem.

net: ipv6: autoconf routes into per-device tables Currently, IPv6 router discovery always puts routes into RT6_TABLE_MAIN. This causes problems for connection managers that want to support multiple simultaneous network connections and want control over which one is used by default (e.g., wifi and wired). To work around this connection managers typically take the routes they prefer and copy them to static routes with low metrics in the main table. This puts the burden on the connection manager to watch netlink to see if the routes have changed, delete the routes when their lifetime expires, etc. Instead, this patch adds a per-interface sysctl to have the kernel put autoconf routes into different tables. This allows each interface to have its own autoconf table, and choosing the default interface (or using different interfaces at the same time for different types of traffic) can be done using appropriate ip rules. The sysctl behaves as follows: - = 0: default. Put routes into RT6_TABLE_MAIN as before. - > 0: manual. Put routes into the specified table. - < 0: automatic. Add the absolute value of the sysctl to the device's ifindex, and use that table. The automatic mode is most useful in conjunction with net.ipv6.conf.default.accept_ra_rt_table. A connection manager or distribution could set it to, say, -100 on boot, and thereafter just use IP rules.

ipv6: clean up anycast when an interface is destroyed If we try to rmmod the driver for an interface while sockets with setsockopt(JOIN_ANYCAST) are alive, some refcounts aren't cleaned up and we get stuck on: unregister_netdevice: waiting for ens3 to become free. Usage count = 1 If we LEAVE_ANYCAST/close everything before rmmod'ing, there is no problem. We need to perform a cleanup similar to the one for multicast in addrconf_ifdown(how == 1).

Linux-2.6.12-rc2 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!

[IPV6]: Add RFC4214 support This patch includes support for the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) per RFC4214. It uses the SIT module, and is configured using extensions to the "iproute2" utility. The diffs are specific to the Linux 2.6.24-rc2 kernel distribution. This version includes the diff for ./include/linux/if.h which was missing in the v2.4 submission and is needed to make the patch compile. The patch has been installed, compiled and tested in a clean 2.6.24-rc2 kernel build area. Signed-off-by: Fred L.
