This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

The following commit: b6c40d68 net: only invoke dev->change_rx_flags when device is UP tried to fix a problem with VLAN devices and promiscuouse flag setting. The issue was that VLAN device was setting a flag on an interface that was down, thus resulting in bad promiscuity count. This commit blocked flag propagation to any device that is currently down. A later commit: deede2fa vlan: Don't propagate flag changes on down interfaces fixed VLAN code to only propagate flags when the VLAN interface is up, thus fixing the same issue as above, only localized to VLAN. The problem we have now is that if we have create a complex stack involving multiple software devices like bridges, bonds, and vlans, then it is possible that the flags would not propagate properly to the physical devices. A simple examle of the scenario is the following: eth0----> bond0 ----> bridge0 ---> vlan50 If bond0 or eth0 happen to be down at the time bond0 is added to the bridge, then eth0 will never have promisc mode set which is currently required for operation as part of the bridge. As a result, packets with vlan50 will be dropped by the interface. The only 2 devices that implement the special flag handling are VLAN and DSA and they both have required code to prevent incorrect flag propagation. As a result we can remove the generic solution introduced in b6c40d68 and leave it to the individual devices to decide whether they will block flag propagation or not.

CPUs can ask for local route via ip_route_input_noref() concurrently. if nh_rth_input is not cached yet, CPUs will proceed to allocate equivalent DSTs on 'lo' and then will try to cache them in nh_rth_input via rt_cache_route() Most of the time they succeed, but on occasion the following two lines: orig = *p; prev = cmpxchg(p, orig, rt); in rt_cache_route() do race and one of the cpus fails to complete cmpxchg. But ip_route_input_slow() doesn't check the return code of rt_cache_route(), so dst is leaking. dst_destroy() is never called and 'lo' device refcnt doesn't go to zero, which can be seen in the logs as: unregister_netdevice: waiting for lo to become free. Usage count = 1 Adding mdelay() between above two lines makes it easily reproducible. Fix it similar to nh_pcpu_rth_output case. Fixes: d2d68ba9 ("ipv4: Cache input routes in fib_info nexthops.")

The tx/rx would access the memory which is out of the desired range. Modify the method of checking the end of the memory to avoid it. For r8152_tx_agg_fill(), the variable remain may become negative. However, the declaration is unsigned, so the while loop wouldn't break when reaching the end of the desied memory. Although to change the declaration from unsigned to signed is enough to fix it, I also modify the checking method for safe. Replace remain = rx_buf_sz - sizeof(*tx_desc) - (u32)((void *)tx_data - agg->head); with remain = rx_buf_sz - (int)(tx_agg_align(tx_data) - agg->head); to make sure the variable remain is always positive. Then, the overflow wouldn't happen. For rx_bottom(), the rx_desc should not be used to calculate the packet length before making sure the rx_desc is in the desired range. Change the checking to two parts. First, check the descriptor is in the memory. The other, using the descriptor to find out the packet length and check if the packet is in the memory.

It appears that driver runs into a problem here if fibsize is too small because we allocate user_srbcmd with fibsize size only but later we access it until user_srbcmd->sg.count to copy it over to srbcmd. It is not correct to test (fibsize < sizeof(*user_srbcmd)) because this structure already includes one sg element and this is not needed for commands without data. So, we would recommend to add the following (instead of test for fibsize == 0).

Pull networking fixes from David Miller: "Mostly these are fixes for fallout due to merge window changes, as well as cures for problems that have been with us for a much longer period of time" 1) Johannes Berg noticed two major deficiencies in our genetlink registration. 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 ...

Johannes Berg says: ==================== genetlink: clean up multicast group APIs The generic netlink multicast group registration doesn't have to be dynamic, and can thus be simplified just like I did with the ops. This removes some complexity in registration code. Additionally, two users of generic netlink already use multicast groups in a wrong way, add workarounds for those two to keep the userspace API working, but at the same time make them not clash with other users of multicast groups as might happen now. While making it all a bit easier, also prevent such abuse by adding checks to the APIs so each family can only use the groups it owns. ==================== Signed-off-by: NDavid S.

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.

snd_nxt must be updated synchronously with sk_send_head. Otherwise tp->packets_out may be updated incorrectly, what may bring a kernel panic. Here is a kernel panic from my host.

[ 146.301158] Call Trace: [ 146.301158] [<ffffffff815ab7f0>] tcp_ack+0xcc0/0x12c0 Before this panic a tcp socket was restored. This socket had sent and unsent data in the write queue. Sent data was restored in repair mode, then the socket was switched from reapair mode and unsent data was restored. After that the socket was switched back into repair mode. In that moment we had a socket where write queue looks like this: snd_una snd_nxt write_seq |_________|________| | sk_send_head After a second switching from repair mode the state of socket was changed: snd_una snd_nxt, write_seq |_________ ________| | sk_send_head This state is inconsistent, because snd_nxt and sk_send_head are not synchronized. Bellow you can find a call trace, how packets_out can be incremented twice for one skb, if snd_nxt and sk_send_head are not synchronized. In this case packets_out will be always positive, even when sk_write_queue is empty. tcp_write_wakeup skb = tcp_send_head(sk); tcp_fragment if (!before(tp->snd_nxt, TCP_SKB_CB(buff)->end_seq)) tcp_adjust_pcount(sk, skb, diff); tcp_event_new_data_sent tp->packets_out += tcp_skb_pcount(skb); I think update of snd_nxt isn't required, when a socket is switched from repair mode. Because it's initialized in tcp_connect_init. Then when a write queue is restored, snd_nxt is incremented in tcp_event_new_data_sent, so it's always is in consistent state. I have checked, that the bug is not reproduced with this patch and all tests about restoring tcp connections work fine.
