Similarly as in commit 8e2f1a63 ("packet: fix packet_direct_xmit for BQL enabled drivers"), we test for __QUEUE_STATE_STACK_XOFF bit in pktgen's xmit, which would not fully fill the device's TX ring for BQL drivers that use netdev_tx_sent_queue(). Fix is to use, similarly as we do in packet sockets, netif_xmit_frozen_or_drv_stopped() test. Signed-off-by:

The at91_ether driver calls macb_mii_init passing a 'struct macb' structure whose tx_clk member is initialized to 0. However, macb_handle_link_change() expects tx_clk to be the result of a call to clk_get, and so IS_ERR(tx_clk) to be true if the clock is invalid. This causes an oops when booting Linux 3.14 on the csb637 board. The following changes avoids this. Signed-off-by:

The old interpreter behaviour was that we returned with 0 whenever we found a division by 0 would take place. In the new interpreter we would currently just skip that instead and continue execution. It's true that a value of 0 as return might not be appropriate in all cases, but current users (socket filters -> drop packet, seccomp -> SECCOMP_RET_KILL, cls_bpf -> unclassified, etc) seem fine with that behaviour. Better this than undefined BPF program behaviour as it's expected that A contains the result of the division. In future, as more use cases open up, we could further adapt this return value to our needs, if necessary. So reintroduce return of 0 for division by 0 as in the old interpreter. Also in case of K which is guaranteed to be 32bit wide, sk_chk_filter() already takes care of preventing division by 0 invoked through K, so we can generally spare us these tests. Signed-off-by:

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter fixes for your net tree, they are: * Use 16-bits offset and length fields instead of 8-bits in the conntrack extension to avoid an overflow when many conntrack extension are used, from Andrey Vagin. * Allow to use cgroup match from LOCAL_IN, there is no apparent reason for not allowing this, from Alexey Perevalov. * Fix build of the connlimit match after recent changes to let it scale up that result in a divide by zero compilation error in UP, from Florian Westphal. * Move the lock out of the structure connlimit_data to avoid a false sharing spotted by Eric Dumazet and Jesper D. Brouer, this needed as part of the recent connlimit scalability improvements, also from Florian Westphal. * Add missing module aliases in xt_osf to fix loading of rules using this match, from Kirill Tkhai. * Restrict set names in nf_tables to 15 characters instead of silently trimming them off, from me. * Fix wrong format in nf_tables request module call for chain types, spotted by Florian Westphal, patch from me. * Fix crash in xtables when it fails to copy the counters back to userspace after having replaced the table already. ==================== Signed-off-by:

All xtables variants suffer from the defect that the copy_to_user() to copy the counters to user memory may fail after the table has already been exchanged and thus exposed. Return an error at this point will result in freeing the already exposed table. Any subsequent packet processing will result in a kernel panic. We can't copy the counters before exposing the new tables as we want provide the counter state after the old table has been unhooked. Therefore convert this into a silent error.

bond_open is not setting the inactive flag correctly for some modes (alb and tlb), resulting in error behavior if the bond has been administratively set down and then back up. This effect should not occur when slaves are added while the bond is up; it's something that only happens after a down/up bounce of the bond. For example, in bond tlb or alb mode, domu send some ARP request which go out from dom0 bond's active slave, then the ARP broadcast request packets go back to inactive slave from switch, because the inactive slave's inactive flag is zero, kernel will receive the packets and pass them to bridge that cause dom0's bridge map domu's MAC address to port of bond, bridge should map domu's MAC to port of vif.

"len" contains sizeof(nf_ct_ext) and size of extensions. In a worst case it can contain all extensions. Bellow you can find sizes for all types of extensions. Their sum is definitely bigger than 256. nf_ct_ext_types[0]->len = 24 nf_ct_ext_types[1]->len = 32 nf_ct_ext_types[2]->len = 24 nf_ct_ext_types[3]->len = 32 nf_ct_ext_types[4]->len = 152 nf_ct_ext_types[5]->len = 2 nf_ct_ext_types[6]->len = 16 nf_ct_ext_types[7]->len = 8 I have seen "len" up to 280 and my host has crashes w/o this patch. The right way to fix this problem is reducing the size of the ecache extension (4) and Florian is going to do this, but these changes will be quite large to be appropriate for a stable tree.

This simple modification allows iptables to work with INPUT chain in combination with cgroup module. It could be useful for counting ingress traffic per cgroup with nfacct netfilter module. There were no problems to count the egress traffic that way formerly. It's possible to get classified sk_buff after PREROUTING, due to socket lookup being done in early_demux (tcp_v4_early_demux). Also it works for udp as well. Trivial usage example, assuming we're in the same shell every step and we have enough permissions: 1) Classic net_cls cgroup initialization: mkdir /sys/fs/cgroup/net_cls mount -t cgroup -o net_cls net_cls /sys/fs/cgroup/net_cls 2) Set up cgroup for interesting application: mkdir /sys/fs/cgroup/net_cls/wget echo 1 > /sys/fs/cgroup/net_cls/wget/net_cls.classid echo $BASHPID > /sys/fs/cgroup/net_cls/wget/cgroup.procs 3) Create kernel counters: nfacct add wget-cgroup-in iptables -A INPUT -m cgroup ! --cgroup 1 -m nfacct --nfacct-name wget-cgroup-in nfacct add wget-cgroup-out iptables -A OUTPUT -m cgroup ! --cgroup 1 -m nfacct --nfacct-name wget-cgroup-out 4) Network usage: wget https://www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.14-rc6.tar.xz 5) Check results: nfacct list Cgroup approach is being used for the DataUsage (counting & blocking traffic) feature for Samsung's modification of the Tizen OS.

Eric points out that the locks can be global. Moreover, both Jesper and Eric note that using only 32 locks increases false sharing as only two cache lines are used. This increases locks to 256 (16 cache lines assuming 64byte cacheline and 4 bytes per spinlock). Suggested-by:

Recycling skb always had been very tough... This time it appears GRO layer can accumulate skb->truesize adjustments made by drivers when they attach a fragment to skb. skb_gro_receive() can only subtract from skb->truesize the used part of a fragment. I spotted this problem seeing TcpExtPruneCalled and TcpExtTCPRcvCollapsed that were unexpected with a recent kernel, where TCP receive window should be sized properly to accept traffic coming from a driver not overshooting skb->truesize.

Commit 5902385a ("tipc: obsolete the remote management feature") introduces a regression where node topology events are not being generated because the publication that triggers this: {0, <z.c.n>, <z.c.n>} is no longer available. This will break applications that rely on node events to discover when nodes join/leave a cluster. We fix this by advertising the node publication when TIPC enters networking mode, and withdraws it upon shutdown. Signed-off-by:

Currently, in packet_direct_xmit() we test the assigned netdevice queue for netif_xmit_frozen_or_stopped() before doing an ndo_start_xmit(). This can have the side-effect that BQL enabled drivers which make use of netdev_tx_sent_queue() internally, set __QUEUE_STATE_STACK_XOFF from within the stack and would not fully fill the device's TX ring from packet sockets with PACKET_QDISC_BYPASS enabled. Instead, use a test without BQL bit so that bursts can be absorbed into the NICs TX ring. Fix and code suggested by Eric Dumazet, thanks! Signed-off-by:

Since commit 015f0688 ("net: net: add a core netdev->tx_dropped counter"), we can now account for TX drops from within the core stack instead of drivers. Therefore, fix packet_direct_xmit() and increase drop count when we encounter a problem before driver's xmit function was called (we do not want to doubly account for it). Suggested-by:

An old inefficiency of the TX path that we are grant mapping the first slot, and then copy the header part to the linear area. Instead, doing a grant copy for that header straight on is more reasonable. Especially because there are ongoing efforts to make Xen avoiding TLB flush after unmap when the page were not touched in Dom0. In the original way the memcpy ruined that. The key changes: - the vif has a tx_copy_ops array again - xenvif_tx_build_gops sets up the grant copy operations - we don't have to figure out whether the header and first frag are on the same grant mapped page or not Note, we only grant copy PKT_PROT_LEN bytes from the first slot, the rest (if any) will be on the first frag, which is grant mapped. If the first slot is smaller than PKT_PROT_LEN, then we grant copy that, and later __pskb_pull_tail will pull more from the frags (if any) Signed-off-by:

For instance, in the following scenario: node A: $ ip link add dev vxlan42 address 2c:c2:60:00:10:20 type vxlan id 42 $ ip addr add dev vxlan42 10.0.0.1/24 $ ip link set up dev vxlan42 $ arp -i vxlan42 -s 10.0.0.2 2c:c2:60:00:01:02 $ bridge fdb add dev vxlan42 to 2c:c2:60:00:01:02 dst <IPv4 address> $ ping 10.0.0.2 node B: $ ip link add dev vxlan42 address 2c:c2:60:00:01:02 type vxlan id 42 $ ip addr add dev vxlan42 10.0.0.2/24 $ ip link set up dev vxlan42 $ arp -i vxlan42 -s 10.0.0.1 2c:c2:60:00:10:20 node B crashes: vxlan42: 2c:c2:60:00:10:20 migrated from 4011:eca4:c0a8:6466:c0a8:6415:8e09:2118 to (invalid address) vxlan42: 2c:c2:60:00:10:20 migrated from 4011:eca4:c0a8:6466:c0a8:6415:8e09:2118 to (invalid address) BUG: unable to handle kernel NULL pointer dereference at 0000000000000046 IP: [<ffffffff8143c459>] ip6_route_output+0x58/0x82 PGD 7bd89067 PUD 7bd4e067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 3.14.0-rc8-hvx-xen-00019-g97a5221f-dirty #154 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 task: ffff88007c774f50 ti: ffff88007c79c000 task.ti: ffff88007c79c000 RIP: 0010:[<ffffffff8143c459>] [<ffffffff8143c459>] ip6_route_output+0x58/0x82 RSP: 0018:ffff88007fd03668 EFLAGS: 00010282 RAX: 0000000000000000 RBX: ffffffff8186a000 RCX: 0000000000000040 RDX: 0000000000000000 RSI: ffff88007b0e4a80 RDI: ffff88007fd03754 RBP: ffff88007fd03688 R08: ffff88007b0e4a80 R09: 0000000000000000 R10: 0200000a0100000a R11: 0001002200000000 R12: ffff88007fd03740 R13: ffff88007b0e4a80 R14: ffff88007b0e4a80 R15: ffff88007bba0c50 FS: 0000000000000000(0000) GS:ffff88007fd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000046 CR3: 000000007bb60000 CR4: 00000000000006e0 Stack: 0000000000000000 ffff88007fd037a0 ffffffff8186a000 ffff88007fd03740 ffff88007fd036c8 ffffffff814320bb 0000000000006e49 ffff88007b8b7360 ffff88007bdbf200 ffff88007bcbc000 ffff88007b8b7000 ffff88007b8b7360 Call Trace: <IRQ> [<ffffffff814320bb>] ip6_dst_lookup_tail+0x2d/0xa4 [<ffffffff814322a5>] ip6_dst_lookup+0x10/0x12 [<ffffffff81323b4e>] vxlan_xmit_one+0x32a/0x68c [<ffffffff814a325a>] ? _raw_spin_unlock_irqrestore+0x12/0x14 [<ffffffff8104c551>] ? lock_timer_base.isra.23+0x26/0x4b [<ffffffff8132451a>] vxlan_xmit+0x66a/0x6a8 [<ffffffff8141a365>] ? ipt_do_table+0x35f/0x37e [<ffffffff81204ba2>] ? selinux_ip_postroute+0x41/0x26e [<ffffffff8139d0c1>] dev_hard_start_xmit+0x2ce/0x3ce [<ffffffff8139d491>] __dev_queue_xmit+0x2d0/0x392 [<ffffffff813b380f>] ? eth_header+0x28/0xb5 [<ffffffff8139d569>] dev_queue_xmit+0xb/0xd [<ffffffff813a5aa6>] neigh_resolve_output+0x134/0x152 [<ffffffff813db741>] ip_finish_output2+0x236/0x299 [<ffffffff813dc074>] ip_finish_output+0x98/0x9d [<ffffffff813dc749>] ip_output+0x62/0x67 [<ffffffff813da9f2>] dst_output+0xf/0x11 [<ffffffff813dc11c>] ip_local_out+0x1b/0x1f [<ffffffff813dcf1b>] ip_send_skb+0x11/0x37 [<ffffffff813dcf70>] ip_push_pending_frames+0x2f/0x33 [<ffffffff813ff732>] icmp_push_reply+0x106/0x115 [<ffffffff813ff9e4>] icmp_reply+0x142/0x164 [<ffffffff813ffb3b>] icmp_echo.part.16+0x46/0x48 [<ffffffff813c1d30>] ? nf_iterate+0x43/0x80 [<ffffffff813d8037>] ? xfrm4_policy_check.constprop.11+0x52/0x52 [<ffffffff813ffb62>] icmp_echo+0x25/0x27 [<ffffffff814005f7>] icmp_rcv+0x1d2/0x20a [<ffffffff813d8037>] ? xfrm4_policy_check.constprop.11+0x52/0x52 [<ffffffff813d810d>] ip_local_deliver_finish+0xd6/0x14f [<ffffffff813d8037>] ? xfrm4_policy_check.constprop.11+0x52/0x52 [<ffffffff813d7fde>] NF_HOOK.constprop.10+0x4c/0x53 [<ffffffff813d82bf>] ip_local_deliver+0x4a/0x4f [<ffffffff813d7f7b>] ip_rcv_finish+0x253/0x26a [<ffffffff813d7d28>] ? inet_add_protocol+0x3e/0x3e [<ffffffff813d7fde>] NF_HOOK.constprop.10+0x4c/0x53 [<ffffffff813d856a>] ip_rcv+0x2a6/0x2ec [<ffffffff8139a9a0>] __netif_receive_skb_core+0x43e/0x478 [<ffffffff812a346f>] ? virtqueue_poll+0x16/0x27 [<ffffffff8139aa2f>] __netif_receive_skb+0x55/0x5a [<ffffffff8139aaaa>] process_backlog+0x76/0x12f [<ffffffff8139add8>] net_rx_action+0xa2/0x1ab [<ffffffff81047847>] __do_softirq+0xca/0x1d1 [<ffffffff81047ace>] irq_exit+0x3e/0x85 [<ffffffff8100b98b>] do_IRQ+0xa9/0xc4 [<ffffffff814a37ad>] common_interrupt+0x6d/0x6d <EOI> [<ffffffff810378db>] ? native_safe_halt+0x6/0x8 [<ffffffff810110c7>] default_idle+0x9/0xd [<ffffffff81011694>] arch_cpu_idle+0x13/0x1c [<ffffffff8107480d>] cpu_startup_entry+0xbc/0x137 [<ffffffff8102e741>] start_secondary+0x1a0/0x1a5 Code: 24 14 e8 f1 e5 01 00 31 d2 a8 32 0f 95 c2 49 8b 44 24 2c 49 0b 44 24 24 74 05 83 ca 04 eb 1c 4d 85 ed 74 17 49 8b 85 a8 02 00 00 <66> 8b 40 46 66 c1 e8 07 83 e0 07 c1 e0 03 09 c2 4c 89 e6 48 89 RIP [<ffffffff8143c459>] ip6_route_output+0x58/0x82 RSP <ffff88007fd03668> CR2: 0000000000000046 ---[ end trace 4612329caab37efd ]--- When vxlan interface is created without explicit group definition, the default_dst protocol family is initialiazed to AF_UNSPEC and the driver assumes IPv4 configuration. On the other side, the default_dst protocol family is used to differentiate between IPv4 and IPv6 cases and, since, AF_UNSPEC != AF_INET, the processing takes the IPv6 path. Making the IPv4 assumption explicit by settting default_dst protocol family to AF_INET4 and preventing mixing of IPv4 and IPv6 addresses in snooped fdb entries fixes the corner case crashes.
