[Group.of.nepali.translators] [Bug 1616107] Re: Kernel oops + system freeze on network-bridge shutdown
Based on the investigation so far, it seems to me that this is entirely a kernel bug, and there is nothing required in the bridge-utils package in order to fix this issue. So I'm marking this bug as Invalid for bridge-utils. The kernel tasks remain open. If this is incorrect, please explain why you expect to need a fix in bridge-utils and reopen that task. ** Changed in: bridge-utils (Ubuntu) Status: Confirmed => Invalid ** Changed in: bridge-utils (Ubuntu Xenial) Status: Confirmed => Invalid ** Changed in: bridge-utils (Ubuntu Yakkety) Status: Confirmed => Invalid -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1616107 Title: Kernel oops + system freeze on network-bridge shutdown Status in bridge-utils package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Status in bridge-utils source package in Xenial: New Status in linux source package in Xenial: Confirmed Status in bridge-utils source package in Yakkety: New Bug description: A Kernel oops leaves Ubuntu 16.04 unusable when a network bridge is brought down on a HPE 530SFP+ 10GBit NIC that uses bnx2x as a driver. This error does not appear in Ubuntu 14.04 however. The error is reproducible whenever issuing the commands "shutdown", "service networking stop" or "brctl delbr br0". Manually creating the bridge and subsequently bringing it down results in the same error. /var/log/kern.log: [...] Aug 23 15:09:46 base1 kernel: [ 617.996677] device ens1f0 left promiscuous mode Aug 23 15:09:46 base1 kernel: [ 617.996699] br0: port 1(ens1f0) entered disabled state Aug 23 15:09:46 base1 kernel: [ 617.996730] BUG: unable to handle kernel NULL pointer dereference at 00d2 Aug 23 15:09:46 base1 kernel: [ 618.008306] IP: [] __vlan_flush+0x18/0x60 [bridge] Aug 23 15:09:46 base1 kernel: [ 618.020549] PGD 10374c0067 PUD 1033927067 PMD 0 Aug 23 15:09:46 base1 kernel: [ 618.032773] Oops: 0002 [#1] SMP Aug 23 15:09:46 base1 kernel: [ 618.044434] Modules linked in: nls_iso8859_1 ipmi_ssif intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm irqbypass sb_edac edac_core joydev bridge stp llc input_leds hpilo lpc_ich ioatdma ipmi_si ipmi_msghandler shpchp mac_hid acpi_power_meter ib_iser rdma_cm iw_cm ib_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid0 multipath linear raid1 hid_generic crct10dif_pclmul crc32_pclmul aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd igb usbhid hid bnx2x dca ahci i2c_algo_bit vxlan libahci ip6_udp_tunnel udp_tunnel ptp pps_core mdio libcrc32c wmi fjes Aug 23 15:09:46 base1 kernel: [ 618.058563] CPU: 3 PID: 4049 Comm: brctl Not tainted 4.4.0-34-generic #53-Ubuntu Aug 23 15:09:46 base1 kernel: [ 618.058564] Hardware name: HP ProLiant DL120 Gen9/ProLiant DL120 Gen9, BIOS P86 05/05/2016 Aug 23 15:09:46 base1 kernel: [ 618.058574] task: 881030676040 ti: 8810341e4000 task.ti: 8810341e4000 Aug 23 15:09:46 base1 kernel: [ 618.058576] RIP: 0010:[] [] __vlan_flush+0x18/0x60 [bridge] Aug 23 15:09:46 base1 kernel: [ 618.058754] RSP: 0018:8810341e7d68 EFLAGS: 00010206 Aug 23 15:09:46 base1 kernel: [ 618.058769] RAX: RBX: RCX: Aug 23 15:09:46 base1 kernel: [ 618.058774] RDX: 881038470848 RSI: RDI: Aug 23 15:09:46 base1 kernel: [ 618.058775] RBP: 8810341e7d78 R08: R09: 8170d949 Aug 23 15:09:46 base1 kernel: [ 618.058776] R10: ead61340 R11: 8810329d2c00 R12: 00c0 Aug 23 15:09:46 base1 kernel: [ 618.058777] R13: 881030044000 R14: 881038470840 R15: Aug 23 15:09:46 base1 kernel: [ 618.058782] FS: 7f9aebc94700() GS:88107fcc() knlGS: Aug 23 15:09:46 base1 kernel: [ 618.058789] CS: 0010 DS: ES: CR0: 80050033 Aug 23 15:09:46 base1 kernel: [ 618.058790] CR2: 00d2 CR3: 00102fe83000 CR4: 001406e0 Aug 23 15:09:46 base1 kernel: [ 618.058802] Stack: Aug 23 15:09:46 base1 kernel: [ 618.058806] 8810356a4c00 8810341e7d98 c0489258 Aug 23 15:09:46 base1 kernel: [ 618.058822] 8810356a4c00 881038470840 8810341e7dc0 c0479bd8 Aug 23 15:09:46 base1 kernel: [ 618.058825] 881038470838 881038470848 88103847 8810341e7df8 Aug 23 15:09:46 base1 kernel: [ 618.058827] Call Trace: Aug 23 15:09:46 base1 kernel: [ 618.058863] [] nbp_vlan_flush+0x28/0x65 [bridge] Aug 23 15:09:46 base1 kernel: [ 618.058870] [] del_nbp+0x98/0x130 [bridge] Aug 23 15:09:46 base1 kernel: [ 618.058889] []
