Created attachment 289885 [details] systemd-networkd config files for reproducing the issue Hello, Our upstream systemd-networkd testsuite[0] managed to hit a NULL pointer dereference in the macsec driver on Arch Linux on kernel 5.7.2, filed as [1]. After minimizing the reproducer, I tried on Fedora Rawhide with 5.8.0-0.rc2.20200623gitdd0d718152e4.1 and apart from the original NULL pointer dereference, there's also "kernel: BUG: sleeping function called from invalid context at include/linux/percpu-rwsem.h:49": [ 76.101843] MACsec IEEE 802.1AE [ 76.160695] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 76.166980] #PF: supervisor read access in kernel mode [ 76.168639] #PF: error_code(0x0000) - not-present page [ 76.170211] PGD 0 P4D 0 [ 76.170993] Oops: 0000 [#1] SMP PTI [ 76.172048] CPU: 0 PID: 581 Comm: systemd-network Not tainted 5.8.0-0.rc2.20200623gitdd0d718152e4.1.fc33.x86_64 #1 [ 76.175034] Hardware name: Red Hat OpenStack Compute, BIOS 1.11.0-2.el7 04/01/2014 [ 76.177432] RIP: 0010:macsec_add_rxsa+0x1a1/0x540 [macsec] [ 76.179285] Code: b6 78 04 48 8b 85 48 ff ff ff 0f b7 30 48 8b 85 e8 fe ff ff 0f b7 50 18 83 ee 04 39 f2 0f 85 f3 5b 00 00 48 8b 95 40 ff ff ff <0f> b7 32 83 ee 04 80 78 20 00 0f 84 31 02 00 00 83 fe 08 0f 85 7e [ 76.185346] RSP: 0018:ffffade24030fb10 EFLAGS: 00010246 [ 76.186924] RAX: ffff9a28f12a9c00 RBX: ffff9a28f0b402a0 RCX: 0000000000000000 [ 76.189178] RDX: 0000000000000000 RSI: 0000000000000010 RDI: 0000000000000246 [ 76.191657] RBP: ffffade24030fc40 R08: 0000000000000001 R09: 0000000000000001 [ 76.193924] R10: 0000000000000001 R11: 0000000000000000 R12: ffff9a28f0ff5900 [ 76.196152] R13: 0000000000000000 R14: ffff9a28f0ff5900 R15: 0000000000000002 [ 76.198246] FS: 00007f6620d82b80(0000) GS:ffff9a28ffc00000(0000) knlGS:0000000000000000 [ 76.200686] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 76.202431] CR2: 0000000000000000 CR3: 000000006f89a001 CR4: 00000000007606f0 [ 76.204581] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 76.206840] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 76.208937] PKRU: 55555554 [ 76.209754] Call Trace: [ 76.210581] ? avc_has_perm_noaudit+0xd8/0x1b0 [ 76.212136] ? find_held_lock+0x32/0x90 [ 76.213356] ? __nla_parse+0x22/0x25 [ 76.214418] ? genl_rcv_msg+0x18e/0x2d0 [ 76.215584] genl_rcv_msg+0x18e/0x2d0 [ 76.216723] ? genl_family_rcv_msg_attrs_parse.isra.0+0x100/0x100 [ 76.218553] netlink_rcv_skb+0x47/0x110 [ 76.219700] genl_rcv+0x24/0x40 [ 76.220622] netlink_unicast+0x16d/0x230 [ 76.221835] netlink_sendmsg+0x23f/0x460 [ 76.223044] sock_sendmsg+0x5e/0x60 [ 76.224275] __sys_sendto+0xf1/0x160 [ 76.225349] ? finish_task_switch+0x6a/0x2b0 [ 76.226592] ? syscall_trace_enter+0x14a/0x330 [ 76.227870] __x64_sys_sendto+0x25/0x30 [ 76.228997] do_syscall_64+0x52/0xb0 [ 76.230207] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 76.231826] RIP: 0033:0x7f6621ed65da [ 76.232913] Code: Bad RIP value.
