RFC 4861 says that the IP source address of the Redirect is the same as the current first-hop router for the specified ICMP Destination Address, so the gateway should be taken into consideration when we find the route for redirect. There was once a check in commit a6279458 ("NDISC: Search over all possible rules on receipt of redirect.") and the check went away in commit b94f1c09 ("ipv6: Use icmpv6_notify() to propagate redirect, instead of rt6_redirect()"). The bug is only "exploitable" on layer-2 because the source address of the redirect is checked to be a valid link-local address but it makes spoofing a lot easier in the same L2 domain nonetheless. Thanks very much for Hannes's help. Signed-off-by:

This patch adds two more ndo ops: ndo_add_rx_vxlan_port() and ndo_del_rx_vxlan_port(). Drivers can get notifications through the above functions about changes of the UDP listening port of VXLAN. Also, when physical ports come up, now they can call vxlan_get_rx_port() in order to obtain the port number(s) of the existing VXLAN interface in case they already up before them. This information about the listening UDP port would be used for VXLAN related offloads. A big thank you to John Fastabend (john.r.fastabend@intel.com) for his input and his suggestions on this patch set.

Currently if there is no listener for a certain group then IPv6 packets for that group are flooded on all ports, even though there might be no host and router interested in it on a port. With this commit they are only forwarded to ports with a multicast router. Just like commit bd4265fe ("bridge: Only flood unregistered groups to routers") did for IPv4, let's do the same for IPv6 with the same reasoning. Signed-off-by:

RFC3810, 10. Security Considerations says under subsection 10.1. Query Message: A forged Version 1 Query message will put MLDv2 listeners on that link in MLDv1 Host Compatibility Mode. This scenario can be avoided by providing MLDv2 hosts with a configuration option to ignore Version 1 messages completely. Hence, implement a MLDv2-only mode that will ignore MLDv1 traffic: echo 2 > /proc/sys/net/ipv6/conf/ethX/force_mld_version or echo 2 > /proc/sys/net/ipv6/conf/all/force_mld_version Note that <all> device has a higher precedence as it was previously also the case in the macro MLD_V1_SEEN() that would "short-circuit" if condition on <all> case.

i) RFC3810, 9.2. Query Interval [QI] says: The Query Interval variable denotes the interval between General Queries sent by the Querier. Default value: 125 seconds. [...] ii) RFC3810, 9.3. Query Response Interval [QRI] says: The Maximum Response Delay used to calculate the Maximum Response Code inserted into the periodic General Queries. Default value: 10000 (10 seconds) [...] The number of seconds represented by the [Query Response Interval] must be less than the [Query Interval]. iii) RFC3810, 9.12. Older Version Querier Present Timeout [OVQPT] says: The Older Version Querier Present Timeout is the time-out for transitioning a host back to MLDv2 Host Compatibility Mode. When an MLDv1 query is received, MLDv2 hosts set their Older Version Querier Present Timer to [Older Version Querier Present Timeout]. This value MUST be ([Robustness Variable] times (the [Query Interval] in the last Query received)) plus ([Query Response Interval]). Hence, on *default* the timeout results in: [RV] = 2, [QI] = 125sec, [QRI] = 10sec [OVQPT] = [RV] * [QI] + [QRI] = 260sec Having that said, we currently calculate [OVQPT] (here given as 'switchback' variable) as ... switchback = (idev->mc_qrv + 1) * max_delay RFC3810, 9.12. says "the [Query Interval] in the last Query received". In section "9.14. Configuring timers", it is said: This section is meant to provide advice to network administrators on how to tune these settings to their network. Ambitious router implementations might tune these settings dynamically based upon changing characteristics of the network. [...] iv) RFC38010, 9.14.2. Query Interval: The overall level of periodic MLD traffic is inversely proportional to the Query Interval. A longer Query Interval results in a lower overall level of MLD traffic. The value of the Query Interval MUST be equal to or greater than the Maximum Response Delay used to calculate the Maximum Response Code inserted in General Query messages. I assume that was why switchback is calculated as is (3 * max_delay), although this setting seems to be meant for routers only to configure their [QI] interval for non-default intervals. So usage here like this is clearly wrong. Concluding, the current behaviour in IPv6's multicast code is not conform to the RFC as switch back is calculated wrongly. That is, it has a too small value, so MLDv2 hosts switch back again to MLDv2 way too early, i.e. ~30secs instead of ~260secs on default. Hence, introduce necessary helper functions and fix this up properly as it should be. Introduced in 06da9228 ("[IPV6]: Add MLDv2 support."). Credits to Hannes Frederic Sowa who also had a hand in this as well. Also thanks to Hangbin Liu who did initial testing. Signed-off-by:

net: sctp: Fix data chunk fragmentation for MTU values which are not multiple of 4 Initially the problem was observed with ipsec, but later it became clear that SCTP data chunk fragmentation algorithm has problems with MTU values which are not multiple of 4. Test program was used which just transmits 2000 bytes long packets to other host. tcpdump was used to observe re-fragmentation in IP layer after SCTP already fragmented data chunks. With MTU 1500: 12:54:34.082904 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 1500) 10.151.38.153.39303 > 10.151.24.91.54321: sctp (1) [DATA] (B) [TSN: 2366088589] [SID: 0] [SSEQ 1] [PPID 0x0] 12:54:34.082933 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 596) 10.151.38.153.39303 > 10.151.24.91.54321: sctp (1) [DATA] (E) [TSN: 2366088590] [SID: 0] [SSEQ 1] [PPID 0x0] 12:54:34.090576 IP (tos 0x2,ECT(0), ttl 63, id 0, offset 0, flags [DF], proto SCTP (132), length 48) 10.151.24.91.54321 > 10.151.38.153.39303: sctp (1) [SACK] [cum ack 2366088590] [a_rwnd 79920] [#gap acks 0] [#dup tsns 0] With MTU 1499: 13:02:49.955220 IP (tos 0x2,ECT(0), ttl 64, id 48215, offset 0, flags [+], proto SCTP (132), length 1492) 10.151.38.153.39084 > 10.151.24.91.54321: sctp[|sctp] 13:02:49.955249 IP (tos 0x2,ECT(0), ttl 64, id 48215, offset 1472, flags [none], proto SCTP (132), length 28) 10.151.38.153 > 10.151.24.91: ip-proto-132 13:02:49.955262 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 600) 10.151.38.153.39084 > 10.151.24.91.54321: sctp (1) [DATA] (E) [TSN: 404355346] [SID: 0] [SSEQ 1] [PPID 0x0] 13:02:49.956770 IP (tos 0x2,ECT(0), ttl 63, id 0, offset 0, flags [DF], proto SCTP (132), length 48) 10.151.24.91.54321 > 10.151.38.153.39084: sctp (1) [SACK] [cum ack 404355346] [a_rwnd 79920] [#gap acks 0] [#dup tsns 0] Here problem in data portion limit calculation leads to re-fragmentation in IP, which is sub-optimal. The problem is max_data initial value, which doesn't take into account the fact, that data chunk must be padded to 4-bytes boundary. It's enough to correct max_data, because all later adjustments are correctly aligned to 4-bytes boundary. After the fix is applied, everything is fragmented correctly for uneven MTUs: 15:16:27.083881 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 1496) 10.151.38.153.53417 > 10.151.24.91.54321: sctp (1) [DATA] (B) [TSN: 3077098183] [SID: 0] [SSEQ 1] [PPID 0x0] 15:16:27.083907 IP (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 600) 10.151.38.153.53417 > 10.151.24.91.54321: sctp (1) [DATA] (E) [TSN: 3077098184] [SID: 0] [SSEQ 1] [PPID 0x0] 15:16:27.085640 IP (tos 0x2,ECT(0), ttl 63, id 0, offset 0, flags [DF], proto SCTP (132), length 48) 10.151.24.91.54321 > 10.151.38.153.53417: sctp (1) [SACK] [cum ack 3077098184] [a_rwnd 79920] [#gap acks 0] [#dup tsns 0] The bug was there for years already, but - is a performance issue, the packets are still transmitted - doesn't show up with default MTU 1500, but possibly with ipsec (MTU 1438) Signed-off-by:

Solution: ========= - Synchronize linux's `include/uapi/linux/in6.h' with glibc's `inet/netinet/in.h'. - Synchronize glibc's `inet/netinet/in.h with linux's `include/uapi/linux/in6.h'. - Allow including the headers in either other. - First header included defines the structures and macros. Details: ======== The kernel promises not to break the UAPI ABI so I don't see why we can't just have the two userspace headers coordinate? If you include the kernel headers first you get those, and if you include the glibc headers first you get those, and the following patch arranges a coordination and synchronization between the two. Let's handle `include/uapi/linux/in6.h' from linux, and `inet/netinet/in.h' from glibc and ensure they compile in any order and preserve the required ABI. These two patches pass the following compile tests: cat >> test1.c <<EOF int main (void) { return 0; } EOF gcc -c test1.c cat >> test2.c <<EOF int main (void) { return 0; } EOF gcc -c test2.c One wrinkle is that the kernel has a different name for one of the members in ipv6_mreq. In the kernel patch we create a macro to cover the uses of the old name, and while that's not entirely clean it's one of the best solutions (aside from an anonymous union which has other issues). I've reviewed the code and it looks to me like the ABI is assured and everything matches on both sides. Notes: - You want netinet/in.h to include bits/in.h as early as possible, but it needs in_addr so define in_addr early. - You want bits/in.h included as early as possible so you can use the linux specific code to define __USE_KERNEL_DEFS based on the _UAPI_* macro definition and use those to cull in.h. - glibc was missing IPPROTO_MH, added here. Compile tested and inspected. Reported-by:
