Description:
Rpc.gssd faults with a kernel oops, and stopping the rpc-gssd service doesn't kill the offending process. Shutdown doesn't go cleanly and requires hard shutdown. Additional info: Gives a kernel oops similar to: NFS: Registering the id_resolver key type Key type id_resolver registered Key type id_legacy registered BUG: unable to handle kernel NULL pointer dereference at 0000000000000c68 IP: [<ffffffffa0a3900c>] put_pipe_version+0x1c/0x80 [auth_rpcgss] PGD 7b2fa067 PUD 764f1067 PMD 0 Oops: 0000 [#1] PREEMPT SMP Modules linked in: rpcsec_gss_krb5 nfsv4 nfsd auth_rpcgss oid_registry nfs_acl xfs crc32c libcrc32c arc4 b43 bcma mac80211 cfg80211 joydev iTCO_wdt iTCO_vendor_support coretemp hp_wmi sparse_keymap ssb rfkill mmc_core pcmcia microcode pcmcia_core pcspkr psmouse serio_raw i2c_i801 lpc_ich 8139too snd_hda_codec_conexant snd_hda_intel 8139cp snd_hda_codec mii snd_hwdep snd_pcm snd_page_alloc snd_timer snd wmi thermal shpchp evdev battery ac processor soundcore nfs lockd sunrpc fscache ext4 crc16 mbcache jbd2 hid_generic usbhid hid sd_mod sr_mod cdrom ata_generic pata_acpi ahci libahci ata_piix libata ehci_pci scsi_mod uhci_hcd ehci_hcd usbcore usb_common i915 video button i2c_algo_bit intel_agp intel_gtt drm_kms_helper drm i2c_core CPU: 0 PID: 822 Comm: rpc.gssd Not tainted 3.12.0-1-ARCH #1 Hardware name: task: ffff88007a60c580 ti: ffff880076646000 task.ti: ffff880076646000 RIP: 0010:[<ffffffffa0a3900c>] [<ffffffffa0a3900c>] put_pipe_version+0x1c/0x80 [auth_rpcgss] RSP: 0000:ffff880076647e38 EFLAGS: 00010202 RAX: ffff88007a60c580 RBX: 0000000000000001 RCX: 00000000c0000100 RDX: ffff880076647fd8 RSI: ffff88007a60c580 RDI: 0000000000000000 RBP: ffff880076647e48 R08: ffff880076646000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000 R13: 0000000000000010 R14: ffff880053defa00 R15: ffff880053dc0d20 FS: 00007f1aa8c4d740(0000) GS:ffff88007ea00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000c68 CR3: 000000007650c000 CR4: 00000000000007f0 Stack: ffff880053defa00 ffff880059cfe5c8 ffff880076647e60 ffffffffa0a3909d ffff8800766865c0 ffff880076647ec0 ffffffffa0a39fe8 0000000000000000 0000000000000065 ffff880059cfe5c8 ffff8800766865c4 0000000100317f41 Call Trace: [<ffffffffa0a3909d>] gss_release_msg+0x2d/0x80 [auth_rpcgss] [<ffffffffa0a39fe8>] gss_pipe_downcall+0x248/0x540 [auth_rpcgss] [<ffffffffa048a866>] rpc_pipe_write+0x56/0x70 [sunrpc] [<ffffffff811a3a8d>] vfs_write+0xbd/0x1e0 [<ffffffff811a44e9>] SyS_write+0x49/0xa0 [<ffffffff814fabad>] system_call_fastpath+0x1a/0x1f Code: 31 c0 e8 26 07 ab e0 31 c0 eb b4 0f 1f 40 00 66 66 66 66 90 55 48 89 e5 41 54 49 89 fc 53 8b 1d ab 42 a6 ff e8 c6 8b 64 e0 85 db <49> 8b 84 24 68 0c 00 00 74 4b 3b 18 77 47 83 eb 01 48 63 db 48 RIP [<ffffffffa0a3900c>] put_pipe_version+0x1c/0x80 [auth_rpcgss] RSP <ffff880076647e38> CR2: 0000000000000c68 ---[ end trace be1777d1c894f03f ]--- INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=18002 jiffies, g=299650, c=299649, q=7598) INFO: Stall ended before state dump start INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=72007 jiffies, g=299650, c=299649, q=25163) INFO: Stall ended before state dump start INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=126013 jiffies, g=299650, c=299649, q=42479) INFO: Stall ended before state dump start INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=180018 jiffies, g=299650, c=299649, q=59833) INFO: Stall ended before state dump start INFO: rcu_preempt detected stalls on CPUs/tasks: {} (detected by 0, t=234023 jiffies, g=299650, c=299649, q=79646) INFO: Stall ended before state dump start Steps to reproduce: Mount a nfs share on the client with rpc-gssd running to a nfs server and will not ever complete the mount resulting in kernel oops using default package configuration (not sure if this makes a difference). Disabling rpc-gssd with systemctl and rebooting clears up the problems with a slight delay for mounting nfs share (that of which was occurring without rpc-nssd). |

The delay you notice when rpc.gssd isn't running is expected: http://www.spinics.net/lists/linux-nfs/msg38268.html
Is jelly using Xen, too?
