2015-09-01netfilter: conntrack: use nf_ct_tmpl_free in CT/synproxy error pathsDaniel Borkmann
Commit 0838aa7fcfcd ("netfilter: fix netns dependencies with conntrack templates") migrated templates to the new allocator api, but forgot to update error paths for them in CT and synproxy to use nf_ct_tmpl_free() instead of nf_conntrack_free(). Due to that, memory is being freed into the wrong kmemcache, but also we drop the per net reference count of ct objects causing an imbalance. In Brad's case, this leads to a wrap-around of net->ct.count and thus lets __nf_conntrack_alloc() refuse to create a new ct object: [ 10.340913] xt_addrtype: ipv6 does not support BROADCAST matching [ 10.810168] nf_conntrack: table full, dropping packet [ 11.917416] r8169 0000:07:00.0 eth0: link up [ 11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 12.815902] nf_conntrack: table full, dropping packet [ 15.688561] nf_conntrack: table full, dropping packet [ 15.689365] nf_conntrack: table full, dropping packet [ 15.690169] nf_conntrack: table full, dropping packet [ 15.690967] nf_conntrack: table full, dropping packet [...] With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs. nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus, to fix the problem, export and use nf_ct_tmpl_free() instead.

2015-08-31tcp: use dctcp if enabled on the route to the initiatorDaniel Borkmann
Currently, the following case doesn't use DCTCP, even if it should: A responder has f.e. Cubic as system wide default, but for a specific route to the initiating host, DCTCP is being set in RTAX_CC_ALGO. The initiating host then uses DCTCP as congestion control, but since the initiator sets ECT(0), tcp_ecn_create_request() doesn't set ecn_ok, and we have to fall back to Reno after 3WHS completes. We were thinking on how to solve this in a minimal, non-intrusive way without bloating tcp_ecn_create_request() needlessly: lets cache the CA ecn option flag in RTAX_FEATURES. In other words, when ECT(0) is set on the SYN packet, set ecn_ok=1 iff route RTAX_FEATURES contains the unexposed (internal-only) DST_FEATURE_ECN_CA. This allows to only do a single metric feature lookup inside tcp_ecn_create_request(). Joint work with Florian Westphal.

2015-08-30netlink: rx mmap: fix POLLIN conditionKen-ichirou MATSUZAWA
Poll() returns immediately after setting the kernel current frame (ring->head) to SKIP from user space even though there is no new frame. And in a case of all frames is VALID, user space program unintensionally sets (only) kernel current frame to UNUSED, then calls poll(), it will not return immediately even though there are VALID frames. To avoid situations like above, I think we need to scan all frames to find VALID frames at poll() like netlink_alloc_skb(), netlink_forward_ring() finding an UNUSED frame at skb allocation.

2015-08-30IB/core: Make ib_dealloc_pd return voidJason Gunthorpe
The majority of callers never check the return value, and even if they did, they can't do anything about a failure. All possible failure cases represent a bug in the caller, so just WARN_ON inside the function instead. This fixes a few random errors: net/rd/iw.c infinite loops while it fails. (racing with EBUSY?) This also lays the ground work to get rid of error return from the drivers. Most drivers do not error, the few that do are broken since it cannot be handled. Since uverbs can legitimately make use of EBUSY, open code the check.

2015-08-30IB/core: lock client data with lists_rwsemHaggai Eran
An ib_client callback that is called with the lists_rwsem locked only for read is protected from changes to the IB client lists, but not from ib_unregister_device() freeing its client data. This is because ib_unregister_device() will remove the device from the device list with lists_rwsem locked for write, but perform the rest of the cleanup, including the call to remove() without that lock. Mark client data that is undergoing de-registration with a new going_down flag in the client data context. Lock the client data list with lists_rwsem for write in addition to using the spinlock, so that functions calling the callback would be able to lock only lists_rwsem for read and let callbacks sleep. Since ib_unregister_client() now marks the client data context, no need for remove() to search the context again, so pass the client data directly to remove() callbacks.

2015-08-29vxlan: do not receive IPv4 packets on IPv6 socketJiri Benc
By default (subject to the sysctl settings), IPv6 sockets listen also for IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in packets received through an IPv6 socket. In addition, it's currently not possible to have both IPv4 and IPv6 vxlan tunnel on the same port (unless bindv6only sysctl is enabled), as it's not possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's no way to specify both IPv4 and IPv6 remote/group IP addresses. Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not done globally in udp_tunnel, as l2tp and tipc seems to work okay when receiving IPv4 packets on IPv6 socket and people may rely on this behavior. The other tunnels (geneve and fou) do not support IPv6. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-29fou: reject IPv6 configJiri Benc
fou does not really support IPv6 encapsulation. After an UDP socket is created in fou_create, the encap_rcv callback is set either to fou_udp_recv or to gue_udp_recv. Both of those unconditionally assume that the received packet has an IPv4 header and access the data at network_header as it was an IPv4 header. This leads to IPv6 flow label being interpreted as IP packet length, etc. Disallow fou tunnel to be configured as IPv6 until real IPv6 support is added to fou.

From Julian Anastasov. 4) Enhance multicast configuration for the IPVS state sync daemon. Also from Julian. 5) Resolve sparse warnings in the nf_dup modules. 6) Fix a linking problem when CONFIG_NF_DUP_IPV6 is not set. 7) Add ICMP codes 5 and 6 to IPv6 REJECT target, they are more informative subsets of code 1. From Andreas Herz. 8) Revert the jumpstack size calculation from mark_source_chains due to chain depth miscalculations, from Florian Westphal. 9) Calm down more sparse warning around the Netfilter tree, again from Florian Westphal. ==================== Signed-off-by: David S.

Make sure we catch future netpoll_send_udp users who use it without disabling irqs and also as a hint for poll_controller users. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-29netfilter: nfnetlink: work around wrong endianess in res_id fieldPablo Neira Ayuso
The convention in nfnetlink is to use network byte order in every header field as well as in the attribute payload. The initial version of the batching infrastructure assumes that res_id comes in host byte order though. The only client of the batching infrastructure is nf_tables, so let's add a workaround to address this inconsistency. We currently have 11 nfnetlink subsystems according to NFNL_SUBSYS_COUNT, so we can assume that the subsystem 2560, ie. htons(10), will not be allocated anytime soon, so it can be an alias of nf_tables from the nfnetlink batching path when interpreting the res_id field. Based on original patch from Florian Westphal. Reported-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
