fan.du 7bda701e01 {vxlan, inet6} Mark vxlan_dev flags with VXLAN_F_IPV6 properly ... Even if user doesn't supply the physical netdev to attach vxlan dev to, and at the same time user want to vxlan sit top of IPv6, mark vxlan_dev flags with VXLAN_F_IPV6 to create IPv6 based socket. Otherwise kernel crashes safely every time spitting below messages, Steps to reproduce: ip link add vxlan0 type vxlan id 42 group ff0e::110 ip link set vxlan0 up [ 62.656266] BUG: unable to handle kernel NULL pointer dereference[ 62.656320] ip (3008) used greatest stack depth: 3912 bytes left at 0000000000000046 [ 62.656423] IP: [<ffffffff816d822d>] ip6_route_output+0xbd/0xe0 [ 62.656525] PGD 2c966067 PUD 2c9a2067 PMD 0 [ 62.656674] Oops: 0000 [#1] SMP [ 62.656781] Modules linked in: vxlan netconsole deflate zlib_deflate af_key [ 62.657083] CPU: 1 PID: 2128 Comm: whoopsie Not tainted 3.12.0+ #182 [ 62.657083] Hardware name: innotek GmbH VirtualBox, BIOS VirtualBox 12/01/2006 [ 62.657083] task: ffff88002e2335d0 ti: ffff88002c94c000 task.ti: ffff88002c94c000 [ 62.657083] RIP: 0010:[<ffffffff816d822d>] [<ffffffff816d822d>] ip6_route_output+0xbd/0xe0 [ 62.657083] RSP: 0000:ffff88002fd038f8 EFLAGS: 00210296 [ 62.657083] RAX: 0000000000000000 RBX: ffff88002fd039e0 RCX: 0000000000000000 [ 62.657083] RDX: ffff88002fd0eb68 RSI: ffff88002fd0d278 RDI: ffff88002fd0d278 [ 62.657083] RBP: ffff88002fd03918 R08: 0000000002000000 R09: 0000000000000000 [ 62.657083] R10: 00000000000001ff R11: 0000000000000000 R12: 0000000000000001 [ 62.657083] R13: ffff88002d96b480 R14: ffffffff81c8e2c0 R15: 0000000000000001 [ 62.657083] FS: 0000000000000000(0000) GS:ffff88002fd00000(0063) knlGS:00000000f693b740 [ 62.657083] CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 [ 62.657083] CR2: 0000000000000046 CR3: 000000002c9d2000 CR4: 00000000000006e0 [ 62.657083] Stack: [ 62.657083] ffff88002fd03a40 ffffffff81c8e2c0 ffff88002fd039e0 ffff88002d96b480 [ 62.657083] ffff88002fd03958 ffffffff816cac8b ffff880019277cc0 ffff8800192b5d00 [ 62.657083] ffff88002d5bc000 ffff880019277cc0 0000000000001821 0000000000000001 [ 62.657083] Call Trace: [ 62.657083] <IRQ> [ 62.657083] [<ffffffff816cac8b>] ip6_dst_lookup_tail+0xdb/0xf0 [ 62.657083] [<ffffffff816caea0>] ip6_dst_lookup+0x10/0x20 [ 62.657083] [<ffffffffa0020c13>] vxlan_xmit_one+0x193/0x9c0 [vxlan] [ 62.657083] [<ffffffff8137b3b7>] ? account+0xc7/0x1f0 [ 62.657083] [<ffffffffa0021513>] vxlan_xmit+0xd3/0x400 [vxlan] [ 62.657083] [<ffffffff8161390d>] dev_hard_start_xmit+0x49d/0x5e0 [ 62.657083] [<ffffffff81613d29>] dev_queue_xmit+0x2d9/0x480 [ 62.657083] [<ffffffff817cb854>] ? _raw_write_unlock_bh+0x14/0x20 [ 62.657083] [<ffffffff81630565>] ? eth_header+0x35/0xe0 [ 62.657083] [<ffffffff8161bc5e>] neigh_resolve_output+0x11e/0x1e0 [ 62.657083] [<ffffffff816ce0e0>] ? ip6_fragment+0xad0/0xad0 [ 62.657083] [<ffffffff816cb465>] ip6_finish_output2+0x2f5/0x470 [ 62.657083] [<ffffffff816ce166>] ip6_finish_output+0x86/0xc0 [ 62.657083] [<ffffffff816ce218>] ip6_output+0x78/0xb0 [ 62.657083] [<ffffffff816eadd6>] mld_sendpack+0x256/0x2a0 [ 62.657083] [<ffffffff816ebd8c>] mld_ifc_timer_expire+0x17c/0x290 [ 62.657083] [<ffffffff816ebc10>] ? igmp6_timer_handler+0x80/0x80 [ 62.657083] [<ffffffff816ebc10>] ? igmp6_timer_handler+0x80/0x80 [ 62.657083] [<ffffffff81051065>] call_timer_fn+0x45/0x150 [ 62.657083] [<ffffffff816ebc10>] ? igmp6_timer_handler+0x80/0x80 [ 62.657083] [<ffffffff81052353>] run_timer_softirq+0x1f3/0x2a0 [ 62.657083] [<ffffffff8102dfd8>] ? lapic_next_event+0x18/0x20 [ 62.657083] [<ffffffff8109e36f>] ? clockevents_program_event+0x6f/0x110 [ 62.657083] [<ffffffff8104a2f6>] __do_softirq+0xd6/0x2b0 [ 62.657083] [<ffffffff8104a75e>] irq_exit+0x7e/0xa0 [ 62.657083] [<ffffffff8102ea15>] smp_apic_timer_interrupt+0x45/0x60 [ 62.657083] [<ffffffff817d3eca>] apic_timer_interrupt+0x6a/0x70 [ 62.657083] <EOI> [ 62.657083] [<ffffffff817d4a35>] ? sysenter_dispatch+0x7/0x1a [ 62.657083] Code: 4d 8b 85 a8 02 00 00 4c 89 e9 ba 03 04 00 00 48 c7 c6 c0 be 8d 81 48 c7 c7 48 35 a3 81 31 c0 e8 db 68 0e 00 49 8b 85 a8 02 00 00 <0f> b6 40 46 c0 e8 05 0f b6 c0 c1 e0 03 41 09 c4 e9 77 ff ff ff [ 62.657083] RIP [<ffffffff816d822d>] ip6_route_output+0xbd/0xe0 [ 62.657083] RSP <ffff88002fd038f8> [ 62.657083] CR2: 0000000000000046 [ 62.657083] ---[ end trace ba8a9583d7cd1934 ]--- [ 62.657083] Kernel panic - not syncing: Fatal exception in interrupt Signed-off-by: Fan Du <fan.du@windriver.com> Reported-by: Ryan Whelan <rcwhelan@gmail.com> Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
