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- trusty' to 'verification-done-trusty'. 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.

Anyone can use the following PPA for hotfixed 3.13 (Trusty) kernel for x86/x64: https://launchpad.net/~inaddy/+archive/ubuntu/lp1443648-x64 And the following PPA for hotfixed kernel for arm64 (moonshot): https://launchpad.net/~inaddy/+archive/ubuntu/lp1443648-arm64 These PPAs should be used for any Trusty machine being an iSER (iSCSI over IB) client. PLEASE - provide feedback for these kernels so I can ask kernel team to SRU my backport. OBS: I had to deal with some conflicts when backporting code from 3.16 to 3.13. I already tested myself and it looks okay but I'll stress test the 3.13 iSER code a bit more. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1443648 Title: Kernel panics on iSER (iscsi over IB) logouts Status in linux package in Ubuntu: Confirmed Bug description: While shutting down the open-iscsi daemon (with an iSER mapped volume from other host) I'm getting the following kernel panic for kernel 3.13.0-49: [272820.948946] scsi15 : iSCSI Initiator over iSER [272843.474551] sd 14:0:0:1: [sdc] Synchronizing SCSI cache [272843.998231] BUG: unable to handle kernel paging request at a03840b7 [272843.998258] IP: [a03840b7] 0xa03840b7 [272843.998278] PGD 1c11067 PUD 1c12063 PMD 80afb5067 PTE 0 [272843.998306] Oops: 0010 [#1] SMP [272843.998324] Modules linked in: rdma_ucm ib_ucm ib_srp scsi_transport_srp scsi_tgt ib_srpt ib_mthca ib_ipa [272843.998742] CPU: 1 PID: 32399 Comm: kworker/1:0 Not tainted 3.13.0-49-generic #81-Ubuntu [272843.998758] Hardware name: HP ProLiant DL360e Gen8, BIOS P73 11/12/2013 [272843.998774] Workqueue: ib_cm cm_work_handler [ib_cm] [272843.998789] task: 88080b72c800 ti: 880802522000 task.ti: 880802522000 [272843.998827] RIP: 0010:[a03840b7] [a03840b7] 0xa03840b7 [272843.998870] RSP: 0018:880802523c28 EFLAGS: 00010296 [272843.998893] RAX: 8800b851d801 RBX: 8807af8482b8 RCX: 00018028 [272843.998929] RDX: 00018029 RSI: 8028 RDI: 88081f003900 [272843.998965] RBP: 880802523c30 R08: R09: 0001 [272843.999002] R10: ea0002e14740 R11: a00e0b9a R12: 88080953e400 [272843.999038] R13: 8807af8482b8 R14: 88080953e400 R15: [272843.999075] FS: () GS:88083f42() knlGS: [272843.999113] CS: 0010 DS: ES: CR0: 80050033 [272843.999136] CR2: a03840b7 CR3: 0008024f1000 CR4: 000407e0 [272843.999173] Stack: [272843.999191] 8807af54 880802523c60 a0386425 8807af8482b8 [272843.999245] 88080953e400 88080acf9fa8 880802523cf0 880802523ca0 [272843.999297] a0384f58 810aacc4 8807af8482b8 8807af8482d0 [272843.999349] Call Trace: [272843.999378] [810aacc4] ? __wake_up+0x44/0x50 [272843.999406] [a03c436b] ? cma_comp_exch+0x4b/0x60 [rdma_cm] [272843.999432] [a03c6429] ? cma_ib_handler+0xf9/0x230 [rdma_cm] [272843.999460] [a01b2166] ? cm_process_work+0x26/0x150 [ib_cm] [272843.999487] [a01b4183] ? cm_work_handler+0xa83/0x161c [ib_cm] [272843.999515] [81083a82] ? process_one_work+0x182/0x450 [272843.999540] [81084871] ? worker_thread+0x121/0x410 [272843.999565] [81084750] ? rescuer_thread+0x430/0x430 [272843.999590] [8108b5b2] ? kthread+0xd2/0xf0 [272843.999615] [8108b4e0] ? kthread_create_on_node+0x1c0/0x1c0 [272843.999641] [8173258c] ? ret_from_fork+0x7c/0xb0 [272843.999666] [8108b4e0] ? kthread_create_on_node+0x1c0/0x1c0 [272843.999691] Code: Bad RIP value.

[Kernel-packages] [Bug 1443648] Re: Kernel panics on iSER (iscsi over IB) logouts
After taking long time bisecting kernel (3.13 - 3.16) it came out that the following commit (and its dependencies) are the ones that fixes the issue: commit b73c3adabdb1e2cb2f2c69bc3cbb9306aa3f9700 Author: Ariel Nahum ari...@mellanox.com Date: Thu May 22 11:00:18 2014 +0300 IB/iser: Simplify connection management iSER relies on refcounting to manage iser connections establishment and teardown. Following commit 39ff05dbbbdb (IB/iser: Enhance disconnection logic for multi-pathing), iser connection maintain 3 references: - iscsi_endpoint (at creation stage) - cma_id (at connection request stage) - iscsi_conn (at bind stage) We can avoid taking explicit refcounts by correctly serializing iser teardown flows (graceful and non-graceful). Our approach is to trigger a scheduled work to handle ordered teardown by gracefully waiting for 2 cleanup stages to complete: 1. Cleanup of live pending tasks indicated by iscsi_conn_stop completion 2. Flush errors processing Each completed stage will notify a waiting worker thread when it is done to allow teardwon continuation. Since iSCSI connection establishment may trigger endpoint disconnect without a successful endpoint connect, we rely on the iscsi - iser binding (.conn_bind) to learn about the teardown policy we should take wrt cleanup stages. Since all cleanup worker threads are scheduled (release_wq) in .ep_disconnect it is safe to assume that when module_exit is called, all cleanup workers are already scheduled. Thus proper module unload shall flush all scheduled works before allowing safe exit, to guarantee no resources got left behind.
