CVE-2023-53632: In the Linux kernel, the following vulnerability has been resolved:  net/mlx5e: Take RTNL lock when needed before calling xdp_set_features()  Hold RTNL lock when calling xdp_set_features() with a registered netdev, as the call triggers the netdev notifiers. This could happen when switching from uplink rep to nic profile for example.  This resolves the following call trace:  RTNL: assertion failed at net/core/dev.c (1953) WARNING: CPU: 6 PID: 112670 at net/core/dev.c:1953 call_netdevice_notifiers_info+0x7c/0x80 Modules linked in: sch_mqprio sch_mqprio_lib act_tunnel_key act_mirred act_skbedit cls_matchall nfnetlink_cttimeout act_gact cls_flower sch_ingress bonding ib_umad ip_gre rdma_ucm mlx5_vfio_pci ipip tunnel4 ip6_gre gre mlx5_ib vfio_pci vfio_pci_core vfio_iommu_type1 ib_uverbs vfio mlx5_core ib_ipoib geneve nf_tables ip6_tunnel tunnel6 iptable_raw openvswitch nsh rpcrdma ib_iser libiscsi scsi_transport_iscsi rdma_cm iw_cm ib_cm ib_core xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink xt_addrtype iptable_nat nf_nat br_netfilter rpcsec_gss_krb5 auth_rpcgss oid_registry overlay zram zsmalloc fuse [last unloaded: ib_uverbs] CPU: 6 PID: 112670 Comm: devlink Not tainted 6.4.0-rc7_for_upstream_min_debug_2023_06_28_17_02 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 RIP: 0010:call_netdevice_notifiers_info+0x7c/0x80 Code: 90 ff 80 3d 2d 6b f7 00 00 75 c5 ba a1 07 00 00 48 c7 c6 e4 ce 0b 82 48 c7 c7 c8 f4 04 82 c6 05 11 6b f7 00 01 e8 a4 7c 8e ff <0f> 0b eb a2 0f 1f 44 00 00 55 48 89 e5 41 54 48 83 e4 f0 48 83 ec RSP: 0018:ffff8882a21c3948 EFLAGS: 00010282 RAX: 0000000000000000 RBX: ffffffff82e6f880 RCX: 0000000000000027 RDX: ffff88885f99b5c8 RSI: 0000000000000001 RDI: ffff88885f99b5c0 RBP: 0000000000000028 R08: ffff88887ffabaa8 R09: 0000000000000003 R10: ffff88887fecbac0 R11: ffff88887ff7bac0 R12: ffff8882a21c3968 R13: ffff88811c018940 R14: 0000000000000000 R15: ffff8881274401a0 FS:  00007fe141c81800(0000) GS:ffff88885f980000(0000) knlGS:0000000000000000 CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f787c28b948 CR3: 000000014bcf3005 CR4: 0000000000370ea0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace:  <TASK>  ? __warn+0x79/0x120  ? call_netdevice_notifiers_info+0x7c/0x80  ? report_bug+0x17c/0x190  ? handle_bug+0x3c/0x60  ? exc_invalid_op+0x14/0x70  ? asm_exc_invalid_op+0x16/0x20  ? call_netdevice_notifiers_info+0x7c/0x80  ? call_netdevice_notifiers_info+0x7c/0x80  call_netdevice_notifiers+0x2e/0x50  mlx5e_set_xdp_feature+0x21/0x50 [mlx5_core]  mlx5e_nic_init+0xf1/0x1a0 [mlx5_core]  mlx5e_netdev_init_profile+0x76/0x110 [mlx5_core]  mlx5e_netdev_attach_profile+0x1f/0x90 [mlx5_core]  mlx5e_netdev_change_profile+0x92/0x160 [mlx5_core]  mlx5e_netdev_attach_nic_profile+0x1b/0x30 [mlx5_core]  mlx5e_vport_rep_unload+0xaa/0xc0 [mlx5_core]  __esw_offloads_unload_rep+0x52/0x60 [mlx5_core]  mlx5_esw_offloads_rep_unload+0x52/0x70 [mlx5_core]  esw_offloads_unload_rep+0x34/0x70 [mlx5_core]  esw_offloads_disable+0x2b/0x90 [mlx5_core]  mlx5_eswitch_disable_locked+0x1b9/0x210 [mlx5_core]  mlx5_devlink_eswitch_mode_set+0xf5/0x630 [mlx5_core]  ? devlink_get_from_attrs_lock+0x9e/0x110  devlink_nl_cmd_eswitch_set_doit+0x60/0xe0  genl_family_rcv_msg_doit.isra.0+0xc2/0x110  genl_rcv_msg+0x17d/0x2b0  ? devlink_get_from_attrs_lock+0x110/0x110  ? devlink_nl_cmd_eswitch_get_doit+0x290/0x290  ? devlink_pernet_pre_exit+0xf0/0xf0  ? genl_family_rcv_msg_doit.isra.0+0x110/0x110  netlink_rcv_skb+0x54/0x100  genl_rcv+0x24/0x40  netlink_unicast+0x1f6/0x2c0  netlink_sendmsg+0x232/0x4a0  sock_sendmsg+0x38/0x60  ? _copy_from_user+0x2a/0x60  __sys_sendto+0x110/0x160  ? __count_memcg_events+0x48/0x90  ? handle_mm_fault+0x161/0x260  ? do_user_addr_fault+0x278/0x6e0  __x64_sys_sendto+0x20/0x30  do_syscall_64+0x3d/0x90  entry_SYSCALL_64_after_hwframe+0x46/0xb0 RIP: 0033 ---truncated---
