* [IPV6]: Call inet6addr_chain notifiers on link downVlad Yasevich2007-07-151-0/+1
| | | | | | | | | | Currently if the link is brought down via ip link or ifconfig down, the inet6addr_chain notifiers are not called even though all the addresses are removed from the interface. This caused SCTP to add duplicate addresses to it's list. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV6]: MSG_ERRQUEUE messages do not pass to connected raw socketsDmitry Butskoy2007-07-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Dmitry Butskoy <dmitry@butskoy.name> Taken from http://bugzilla.kernel.org/show_bug.cgi?id=8747 Problem Description: It is related to the possibility to obtain MSG_ERRQUEUE messages from the udp and raw sockets, both connected and unconnected. There is a little typo in net/ipv6/icmp.c code, which prevents such messages to be delivered to the errqueue of the correspond raw socket, when the socket is CONNECTED. The typo is due to swap of local/remote addresses. Consider __raw_v6_lookup() function from net/ipv6/raw.c. When a raw socket is looked up usual way, it is something like: sk = __raw_v6_lookup(sk, nexthdr, daddr, saddr, IP6CB(skb)->iif); where "daddr" is a destination address of the incoming packet (IOW our local address), "saddr" is a source address of the incoming packet (the remote end). But when the raw socket is looked up for some icmp error report, in net/ipv6/icmp.c:icmpv6_notify() , daddr/saddr are obtained from the echoed fragment of the "bad" packet, i.e. "daddr" is the original destination address of that packet, "saddr" is our local address. Hence, for icmpv6_notify() must use "saddr, daddr" in its arguments, not "daddr, saddr" ... Steps to reproduce: Create some raw socket, connect it to an address, and cause some error situation: f.e. set ttl=1 where the remote address is more than 1 hop to reach. Set IPV6_RECVERR . Then send something and wait for the error (f.e. poll() with POLLERR|POLLIN). You should receive "time exceeded" icmp message (because of "ttl=1"), but the socket do not receive it. If you do not connect your raw socket, you will receive MSG_ERRQUEUE successfully. (The reason is that for unconnected socket there are no actual checks for local/remote addresses).

* [IPV6] MIP6: Loadable module support for MIPv6.Masahide NAKAMURA2007-07-1114-40/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* bonding / ipv6: no addrconf for slaves separately from masterJay Vosburgh2007-07-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, when a device is enslaved to bonding, if ipv6 is active then addrconf will be initated on the slave (because it is closed then opened during the enslavement processing). This causes DAD and RS packets to be sent from the slave. These packets in turn can confuse switches that perform ipv6 snooping, causing them to incorrectly update their forwarding tables (if, e.g., the slave being added is an inactve backup that won't be used right away) and direct traffic away from the active slave to a backup slave (where the incoming packets will be dropped). This patch alters the behavior so that addrconf will only run on the master device itself. I believe this is logically correct, as it prevents slaves from having an IPv6 identity independent from the master. This is consistent with the IPv4 behavior for bonding. This is accomplished by (a) having bonding set IFF_SLAVE sooner in the enslavement processing than currently occurs (before open, not after), and (b) having ipv6 addrconf ignore UP and CHANGE events on slave devices. The eql driver also uses the IFF_SLAVE flag. I inspected eql, and I believe this change is reasonable for its usage of IFF_SLAVE, but I did not test it.

* [IPV6] addrconf: Fix IPv6 on tuntap tunnelsHerbert Xu2007-06-141-22/+11
| | | | | | | | | | | | | | | | | | | | | | | The recent patch that added ipv6_hwtype is broken on tuntap tunnels. Indeed, it's broken on any device that does not pass the ipv6_hwtype test. The reason is that the original test only applies to autoconfiguration, not IPv6 support. IPv6 support is allowed on any device. In fact, even with the ipv6_hwtype patch applied you can still add IPv6 addresses to any interface that doesn't pass thw ipv6_hwtype test provided that they have a sufficiently large MTU. This is a serious problem because come deregistration time these devices won't be cleaned up properly. I've gone back and looked at the rationale for the patch. It appears that the real problem is that we were creating IPv6 devices even if the MTU was too small. So here's a patch which fixes that and reverts the ipv6_hwtype stuff.

| | | | | | | | | | | | | | When a helper module is unloaded all conntracks refering to it have their helper pointer NULLed out, leading to lots of races.

* [XFRM]: Allow packet drops during larval state resolution.David S. Miller2007-05-255-8/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current IPSEC rule resolution behavior we have does not work for a lot of people, even though technically it's an improvement from the -EAGAIN buisness we had before. Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S. Miller <davem@davemloft.net>
