"value": "In the Linux kernel, the following vulnerability has been resolved:\n\namt: Don't support cross-netns setup.\n\nWhen a lower device is unregistered, amt_device_event() tries\nto unregister its upper AMT device, but it has two problems.\n\n 1. amt_lookup_upper_dev() looks up an upper device in the\n lower device's netns only\n\n 2. amt_device_event() unregisters a single upper device only\n\nIf AMT device is created on a lower device in another netns,\nremoving the lower device triggers the splat below and gets\nstuck until all upper devices are removed. [0]\n\nThe cross-netns setup seems unintentional considering 1. and\nthe following points:\n\n * amt_link_setup() sets dev->netns_immutable to true\n * skb_scrub_packet() is not called in the fast path\n * iproute2 binary fails to find cross-netns lower device via\n link-netns:\n # ip -n ns1 link add amt0 link-netns ns2 type amt dev veth1\n Cannot find device \"veth1\"\n\nInstead of supporting it properly and preparing for per-netns\nnetdev unreg, let's forbid cross-netns setup.\n\nNote that the problem 2. needs a separate fix.\n\n[0]:\nWARNING: net/core/dev.c:12518 at unregister_netdevice_many_notify+0x1cce/0x2250, CPU#48: ip/2031\nModules linked in:\nCPU: 48 UID: 0 PID: 2031 Comm: ip Not tainted 7.2.0-rc5+ #27 PREEMPT(full)\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.17.0-debian-1.17.0-1 04/01/2014\nRIP: 0010:unregister_netdevice_many_notify (net/core/dev.c:12518)\nCode: 89 ef e8 d5 52 ae fe e9 d0 f4 ff ff 48 8d 3d f9 3b 9c 02 48 c7 c6 c0 0b 63 84 ba ab 1f 00 00 67 48 0f b9 3a e9 65 ff ff ff 90 <0f> 0b 90 eb 81 48 8d 3d f6 3b 9c 02 48 c7 c6 c0 0b 63 84 ba e2 1f\nRSP: 0018:ffffc90004abf160 EFLAGS: 00010212\nRAX: ffff888104d38260 RBX: ffff88800b0911b8 RCX: dffffc0000000000\nRDX: 0000000000000000 RSI: 0000000000000008 RDI: ffffffff85b9f880\nRBP: ffffc90004abf2d0 R08: ffffffff85b9f887 R09: 1ffffffff0b73f10\nR10: dffffc0000000000 R11: fffffbfff0b73f11 R12: ffff88800b091d08\nR13: ffff88800b091178 R14: dffffc0000000000 R15: ffff88800b091000\nFS: 00007f555b86c600(0000) GS:ffff8881942a0000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 0000562107d489c0 CR3: 0000000109a40002 CR4: 0000000000372ef0\nCall Trace:\n <TASK>\n rtnl_dellink (net/core/rtnetlink.c:3632 net/core/rtnetlink.c:3674)\n rtnetlink_rcv_msg (net/core/rtnetlink.c:7112)\n netlink_rcv_skb (net/netlink/af_netlink.c:2556)\n netlink_unicast (net/netlink/af_netlink.c:1319)\n netlink_sendmsg (net/netlink/af_netlink.c:1900)\n ____sys_sendmsg (net/socket.c:775)\n __sys_sendmsg (net/socket.c:2738)\n do_syscall_64 (arch/x86/entry/syscall_64.c:63)\n entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:121)\n...\nunregister_netdevice: waiting for veth0 to become free.
