* ipv6: simplify detection of first operational link-local address on interfaceHannes Frederic Sowa2014-01-171-1/+0
| | | | | | | | | | | | | | | | | | | In commit 1ec047eb4751e3 ("ipv6: introduce per-interface counter for dad-completed ipv6 addresses") I build the detection of the first operational link-local address much to complex. Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

* sctp: Remove outqueue empty stateVlad Yasevich2014-01-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SCTP outqueue structure maintains a data chunks that are pending transmission, the list of chunks that are pending a retransmission and a length of data in flight. It also tries to keep the emtpy state so that it can performe shutdown sequence or notify user. The problem is that the empy state is inconsistently tracked. It is possible to completely drain the queue without sending anything when using PR-SCTP. In this case, the empty state will not be correctly state as report by Jamal Hadi Salim <jhs@mojatatu.com>. This can cause an association to be perminantly stuck in the SHUTDOWN_PENDING state. Additionally, SCTP is incredibly inefficient when setting the empty state. Even though all the data is availaible in the outqueue structure, we ignore it and walk a list of trasnports. In the end, we can completely remove the extra empty state and figure out if the queue is empty by looking at 3 things: length of pending data, length of in-flight data, and exisiting of retransmit data. All of these are already in the strucutre.

* net: llc: fix order of evaluation in llc_conn_ac_inc_vr_by_1Daniel Borkmann2014-01-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Function llc_conn_ac_inc_vr_by_1() evaluates via macro PDU_GET_NEXT_Vr() into ... llc_sk(sk)->vR = ++llc_sk(sk)->vR & 0xffffffffffffff7f ... but the order in which the side effects take place is undefined because there is no intervening sequence point. As llc_sk(sk)->vR is written in llc_sk(sk)->vR (assignment left-hand side) and written in ++llc_sk(sk)->vR & 0xffffffffffffff7f this might possibly yield undefined behavior. The final value of llc_sk(sk)->vR is ambiguous, because, depending on the order of expression evaluation, the increment may occur before, after, or interleaved with the assignment. In C, evaluating such an expression yields undefined behavior. Since we're doing the increment via PDU_GET_NEXT_Vr() macro and the only place it is being used is from llc_conn_ac_inc_vr_by_1(), in order to increment vR by 1 with a follow-up optimized modulo, rewrite the expression into ((vR + 1) & CONST) in order to fix this.

* sctp: properly latch and use autoclose value from sock to associationNeil Horman2013-12-101-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, sctp associations latch a sockets autoclose value to an association at association init time, subject to capping constraints from the max_autoclose sysctl value. This leads to an odd situation where an application may set a socket level autoclose timeout, but sliently sctp will limit the autoclose timeout to something less than that. Fix this by modifying the autoclose setsockopt function to check the limit, cap it and warn the user via syslog that the timeout is capped. This will allow getsockopt to return valid autoclose timeout values that reflect what subsequent associations actually use. While were at it, also elimintate the assoc->autoclose variable, it duplicates whats in the timeout array, which leads to multiple sources for the same information, that may differ (as the former isn't subject to any capping). This gives us the timeout information in a canonical place and saves some space in the association structure as well.

* tcp_memcontrol: Cleanup/fix cg_proto->memory_pressure handling.Eric W. Biederman2013-12-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | kill memcg_tcp_enter_memory_pressure. The only function of memcg_tcp_enter_memory_pressure was to reduce deal with the unnecessary abstraction that was tcp_memcontrol. Now that struct tcp_memcontrol is gone remove this unnecessary function, the unnecessary function pointer, and modify sk_enter_memory_pressure to set this field directly, just as sk_leave_memory_pressure cleas this field directly. This fixes a small bug I intruduced when killing struct tcp_memcontrol that caused memcg_tcp_enter_memory_pressure to never be called and thus failed to ever set cg_proto->memory_pressure. Remove the cg_proto enter_memory_pressure function as it now serves no useful purpose. Don't test cg_proto->memory_presser in sk_leave_memory_pressure before clearing it. The test was originally there to ensure that the pointer was non-NULL. Now that cg_proto is not a pointer the pointer does not matter. Signed-off-by: "Eric W.

| | | | | | | | | | | | | | | | | | | The code to detect fragments in checksum_setup() was missing for IPv4 and too eager for IPv6. (It transpires that Windows seems to send IPv6 packets with a fragment header even if they are not a fragment - i.e. offset is zero, and M bit is not set).

The recv_error and rxpmtu functions relied on the recvmsg functions to set up addr_len before.

Some genetlink protocols we passing in constant counts for their ops array rather than something like ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were using fixed IDs for their multicast groups. We have to retain these fixed IDs to keep existing userland tools working, but reserve them so that other multicast groups used by other protocols can not possibly conflict. In dealing with these two problems, we actually now use less state management for genetlink operations and multicast groups. 2) When configuring interface hardware timestamping, fix several drivers that simply do not validate that the hwtstamp_config value is one the driver actually supports. From Ben Hutchings. 3) Invalid memory references in mwifiex driver, from Amitkumar Karwar. 4) In dev_forward_skb(), set the skb->protocol in the right order relative to skb_scrub_packet(). From Alexei Starovoitov. 5) Bridge erroneously fails to use the proper wrapper functions to make calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki Makita. 6) When detaching a bridge port, make sure to flush all VLAN IDs to prevent them from leaking, also from Toshiaki Makita. 7) Put in a compromise for TCP Small Queues so that deep queued devices that delay TX reclaim non-trivially don't have such a performance decrease. One particularly problematic area is 802.11 AMPDU in wireless. From Eric Dumazet. 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts here. Fix from Eric Dumzaet, reported by Dave Jones. 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn. 10) When computing mergeable buffer sizes, virtio-net fails to take the virtio-net header into account. From Michael Dalton. 11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic bumping, this one has been with us for a while. From Eric Dumazet. 12) Fix NULL deref in the new TIPC fragmentation handling, from Erik Hugne. 13) 6lowpan bit used for traffic classification was wrong, from Jukka Rissanen. 14) macvlan has the same issue as normal vlans did wrt. propagating LRO disabling down to the real device, fix it the same way. From Michal Kubecek. 15) CPSW driver needs to soft reset all slaves during suspend, from Daniel Mack. 16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet. 17) The xen-netfront RX buffer refill timer isn't properly scheduled on partial RX allocation success, from Ma JieYue. 18) When ipv6 ping protocol support was added, the AF_INET6 protocol initialization cleanup path on failure was borked a little. Fix from Vlad Yasevich. 19) If a socket disconnects during a read/recvmsg/recvfrom/etc that blocks we can do the wrong thing with the msg_name we write back to userspace. From Hannes Frederic Sowa. There is another fix in the works from Hannes which will prevent future problems of this nature. 20) Fix route leak in VTI tunnel transmit, from Fan Du. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits) genetlink: make multicast groups const, prevent abuse genetlink: pass family to functions using groups genetlink: add and use genl_set_err() genetlink: remove family pointer from genl_multicast_group genetlink: remove genl_unregister_mc_group() hsr: don't call genl_unregister_mc_group() quota/genetlink: use proper genetlink multicast APIs drop_monitor/genetlink: use proper genetlink multicast APIs genetlink: only pass array to genl_register_family_with_ops() tcp: don't update snd_nxt, when a socket is switched from repair mode atm: idt77252: fix dev refcnt leak xfrm: Release dst if this dst is improper for vti tunnel netlink: fix documentation typo in netlink_set_err() be2net: Delete secondary unicast MAC addresses during be_close be2net: Fix unconditional enabling of Rx interface options net, virtio_net: replace the magic value ping: prevent NULL pointer dereference on write to msg_name bnx2x: Prevent "timeout waiting for state X" bnx2x: prevent CFC attention bnx2x: Prevent panic during DMAE timeout ...
| * genetlink: make multicast groups const, prevent abuseJohannes Berg2013-11-191-17/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns.

The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

For example for matching, frags may not be matched correctly. Take following example: <example> On HOSTA do: ip6tables -I INPUT -p icmpv6 -j DROP ip6tables -I INPUT -p icmpv6 -m icmp6 --icmpv6-type 128 -j ACCEPT and on HOSTB you do: ping6 HOSTA -s2000 (MTU is 1500) Incoming echo requests will be filtered out on HOSTA. This issue does not occur with smaller packets than MTU (where fragmentation does not happen) </example> As was discussed previously, the only correct solution seems to be to use reassembled skb instead of separete frags. Doing this has positive side effects in reducing sk_buff by one pointer (nfct_reasm) and also the reams dances in ipvs and conntrack can be removed. Future plan is to remove net/ipv6/netfilter/nf_conntrack_reasm.c entirely and use code in net/ipv6/reassembly.c instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling and disabling SSP debug mode is useful for development. This adds a debugfs entry that allows to configure the SSP debug mode. On purpose this has been implemented as debugfs entry and not a public API since it is really only useful during testing and development.

| | * | Bluetooth: Remove interval parameter from HCI connectionMarcel Holtmann2013-10-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The conn->interval parameter of HCI connections is not used at all and so just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
| | * | Bluetooth: Select the own address type during initial setup phaseMarcel Holtmann2013-10-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The own address type is based on the fact if the controller has a public address or not. This means that this detail can be just configured once during setup phase. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

| | * | Bluetooth: Add address type to device blacklist tableMarcel Holtmann2013-10-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device blacklist is not taking care of the address type. Actually store the address type in the list entries and also use them when looking up addresses in the table. This is actually a serious bug. When adding a LE public address to the blacklist, then it would be blocking a device on BR/EDR. And this is not the expected behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This seems to be a left-over. The module parameter enable_hs has been removed, but its extern declaration is still present.
