[Kernel-packages] [Bug 1579135] Re: AppArmor profile reloading causes an intermittent kernel BUG
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

I'm running through the tests in qemu on a current 16 image (built yesteray), and hitting this most of the time with the homeInterface Suite tests in particular. The networkInterfaceSuite tests also seem to produce a similar problem: sudo snap connect home-consumer:home ubuntu-core:home [/] Connect home-consumer:home to ubuntu-core:home home-consumer.writer /home/ubuntu/snap/snappy-tests/11/writable sudo snap disconnect home-consumer:home ubuntu-core:home [ 519.416354] BUG: unable to handle kernel NULL pointer dereference at 0038 [ 519.417327] IP: [] profile_cmp+0x2f/0x180 [ 519.417978] PGD 1f26a067 PUD 1aa4f067 PMD 0 [ 519.418574] Oops: [#1] SMP [ 519.419032] Modules linked in: kvm_intel joydev kvm ppdev snd_pcm snd_timer irqbypass snd soundcore parport_pc pcspkr input_leds floppy parport evbug psmouse e1000 8250_fintek i2c_piix4 mac_hid pata_acpi serio_raw autofs4 nls_iso8859_1 usb_storage ahci libahci squashfs [ 519.422747] CPU: 0 PID: 1915 Comm: apparmor_parser Tainted: GW 4.4.0-21-generic #37-Ubuntu [ 519.423689] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Ubuntu-1.8.2-1ubuntu1 04/01/2014 [ 519.424627] task: 88001d23cb00 ti: 88001b58c000 task.ti: 88001b58c000 [ 519.425385] RIP: 0010:[] [] profile_cmp+0x2f/0x180 [ 519.426242] RSP: 0018:88001b58fcb0 EFLAGS: 00010086 [ 519.426791] RAX: RBX: 88001b1b1400 RCX: 0006 [ 519.427628] RDX: RSI: RDI: 0009 [ 519.428405] RBP: 88001b58fcc0 R08: 000a R09: 0274 [ 519.429127] R10: 88001f236890 R11: 0274 R12: [ 519.429956] R13: 000b R14: R15: 88001abff950 [ 519.430957] FS: 7f0c1609b740() GS:88001fc0() knlGS: [ 519.432256] CS: 0010 DS: ES: CR0: 80050033 [ 519.433030] CR2: 0038 CR3: 1b14b000 CR4: 06f0 [ 519.433868] Stack: [ 519.434204] 000c 88001abff9b0 88001b58fd08 8138a0c3 [ 519.435355] 00011f2b9450 880c 88001abff950 88001b1b1760 [ 519.436480] 88001f236848 88001abff900 88001f236840 88001b58fd98 [ 519.437609] Call Trace: [ 519.438007] [] aa_vec_unique+0x163/0x240 [ 519.438709] [] __aa_labelset_update_subtree+0x687/0x820 [ 519.439537] [] aa_replace_profiles+0x59b/0xb70 [ 519.440268] [] ? __kmalloc+0x22e/0x250 [ 519.440944] [] policy_update+0x9f/0x1f0 [ 519.441617] [] profile_replace+0x13/0x20 [ 519.442299] [] __vfs_write+0x18/0x40 [ 519.443032] [] vfs_write+0xa9/0x1a0 [ 519.443721] [] ? do_sys_open+0x1bf/0x2a0 [ 519.16] [] SyS_write+0x55/0xc0 [ 519.445042] [] entry_SYSCALL_64_fastpath+0x16/0x71 [ 519.445802] Code: 00 55 48 85 ff 48 89 e5 41 54 53 49 89 f4 48 89 fb 0f 84 8b 00 00 00 4d 85 e4 0f 84 aa 00 00 00 48 83 7b 38 00 0f 84 c9 00 00 00 <49> 83 7c 24 38 00 0f 84 e8 00 00 00 48 83 7b 08 00 0f 84 07 01 [ 519.451336] RIP [] profile_cmp+0x2f/0x180 [ 519.452088] RSP [ 519.452570] CR2: 0038 [ 519.453032] ---[ end trace 65ff12ee2e7c26af ]--- The details of this test can be found at: https://github.com/ubuntu-core/snappy/tree/master/integration-tests/data/snaps/home-consumer Will follow up with more details To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/
