vbus-enet: the backpressure code should initially use sown to
check for ring full condition. There is a small window
where full=0 and sown=1 until the host clears it
int iter_pop.

I've been doing some benchmarks with alacrityvm and ran across couple of BUGs. The setup I'm using has two venet-tap/vbus_enet interfaces on the guest which are bridged to two physical interfaces on the host. There's an external machine with two interfaces sending IP traffic which the guest forwards. The kernels on both host and guest were running alacrityvm kernel with last commit b8fbfd1629f43fd3d9ab2819adcdc5c5a287501f The kernel .configs are available at http://sisapiiri.net/~jmaki/vbus/ --- [ 0.163438] BUG: unable to handle kernel NULL pointer dereference at (null) [ 0.164008] IP: [<ffffffff8127637b>] __mutex_lock_common+0xcc/0x229 [ 0.164008] PGD 0 [ 0.164008] Oops: 0002 [#1] PREEMPT SMP [ 0.164008] last sysfs file: [ 0.164008] CPU 0 [ 0.164008] Modules linked in: [ 0.164008] Pid: 1, comm: swapper Not tainted 2.6.32.8-alacrityvm #1 [ 0.164008] RIP: 0010:[<ffffffff8127637b>] [<ffffffff8127637b>] __mutex_lock_common+0xcc/0x229 [ 0.164008] RSP: 0018:ffff88001f433e48 EFLAGS: 00010246 [ 0.164008] RAX: 0000000000000000 RBX: ffffffff8145e888 RCX: ffffffff8127621c [ 0.164008] RDX: ffff88001f433e58 RSI: 0000000000000003 RDI: ffffffff8145e88c [ 0.164008] RBP: ffffffff8145e88c R08: 0000000000000000 R09: ffffffff8136e9e0 [ 0.164008] R10: ffff88001f504400 R11: 000000007ffffffc R12: ffff88001f450000 [ 0.164008] R13: ffff88001f432000 R14: 0000000000000002 R15: ffffffff8145e890 [ 0.164008] FS: 0000000000000000(0000) GS:ffff880001600000(0000) knlGS:0000000000000000 [ 0.164008] CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b [ 0.164008] CR2: 0000000000000000 CR3: 0000000001001000 CR4: 00000000000006b0 [ 0.164008] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 0.164008] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 0.164008] Process swapper (pid: 1, threadinfo ffff88001f432000, task ffff88001f450000) [ 0.164008] Stack: [ 0.164008] ffffffff8145e8a0 ffffffff8137a9f8 ffffffff8145e890 0000000000000000 [ 0.164008] <0> ffffffff8135bfa8 0000ffffffff813b ffffffff811acb8f ffffffff8145e888 [ 0.164008] <0> ffffffff8137ac60 0000000000000004 0000000000000004 ffffffff8135bfa8 [ 0.164008] Call Trace: [ 0.164008] [<ffffffff811acb8f>] ? device_create+0x2c/0x31 [ 0.164008] [<ffffffff8127621c>] ? mutex_lock+0x12/0x2b [ 0.164008] [<ffffffff81064c76>] ? vbus_devclass_register+0x19/0x7f [ 0.164008] [<ffffffff81194e69>] ? misc_register+0x107/0x126 [ 0.164008] [<ffffffff813caf31>] ? vbus_admin_init+0x0/0x14 [ 0.164008] [<ffffffff813caf45>] ? venettap_init+0x0/0x14 [ 0.164008] [<ffffffff81009050>] ? do_one_initcall+0x4f/0x149 [ 0.164008] [<ffffffff813b9482>] ? kernel_init+0x14b/0x1a3 [ 0.164008] [<ffffffff8100be7a>] ? child_rip+0xa/0x20 [ 0.164008] [<ffffffff813b9337>] ? kernel_init+0x0/0x1a3 [ 0.164008] [<ffffffff8100be70>] ? child_rip+0x0/0x20 [ 0.164008] Code: f3 90 eb 9a 48 8d 6b 04 4c 8d 7b 08 48 89 ef e8 5d 0c 00 00 48 8b 43 10 48 8d 54 24 10 48 89 44 24 18 48 89 53 10 4c 89 7c 24 10 <48> 89 10 48 83 ca ff 4c 89 64 24 20 48 89 d0 87 03 ff c8 0f 84 [ 0.164008] RIP [<ffffffff8127637b>] __mutex_lock_common+0xcc/0x229 [ 0.164008] RSP <ffff88001f433e48> [ 0.164008] CR2: 0000000000000000 [ 0.196670] ---[ end trace a7919e7f17c0a725 ]--- [ 0.197301] note: swapper[1] exited with preempt_count 3 [ 0.197951] Kernel panic - not syncing: Attempted to kill init!

Hi All, I have created #alacrityvm on OFTC (irc.oftc.net) for live-chat discussions of the project, including user or developer issues. Hope to see you there, -Greg |

Hi all, FYI, I have created a new git tree to house guest drivers. The honorary first commit goes to the scripts that I have to generate a KMP for linux guests: Here is the linux/README: ----------------------- How to use: 1) make KSRC=./path/to/alacrityvm/linux-2.6.git This results in a .src.rpm being generated, the location of which should be reported by the build tool. For example: "Wrote: /usr/src/packages/SRPMS/alacrityvm-drivers-0.2-1.src.rpm" 2) rpmbuild --rebuild ./path/to/src.rpm For example: rpmbuild --rebuild /usr/src/packages/SRPMS/alacrityvm-drivers-0.2-1.src.rpm ---------------------- I have updated the "repositories" page on the wiki: http://developer.novell.com/wiki/index.php/AlacrityVM/Repositories Kind Regards, -Greg |

Thank you to Pat Mullaney for forward porting the tree from 31.y to 32.8 and 33-rc8 http://git.kernel.org/?p=linux/kernel/git/ghaskins/alacrityvm/linux-2.6.git;a=summary We have now officially updated the kernel tree "master" to 33-rc8. We also have parallel branches for 2.6.31.y and 2.6.32.y, and plan to maintain 1-2 stable releases behind the latest going forward. Let us know if there are any problems or concerns. -Greg |

If you have the git sources somewhere, I could look to (potentially) update my sources and see if it is already fixed or not.

Hi Dhavai, I am having trouble reproducing this (albeit on a 2.6.33-rc8 kernel) and I wanted to make sure I was trying correctly. Is that just a ping flood (ping -f destip) directed at the guest from any other host. Thanks.

Hi, So I have been experimenting about a bit with alacrityvm. One of the things I have been doing to measure latencies is to flood ping the guest. This exposes the following BUG/panic in the guest. ------------[ cut here ]------------ kernel BUG at drivers/net/vbus-enet.c:831! invalid opcode: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:01.1/host0/target0:0:0/0:0:0:0/block/sda/size Modules linked in: sunrpc ipv6 dm_multipath ppdev parport_pc parport vbus_enet pcspkr i2c_piix4 i2c_core floppy ata_generic pata_acpi [last unloaded: microcode] Pid: 0, comm: swapper Not tainted (2.6.31.6-avm #3) EIP: 0060:[<f81b4909>] EFLAGS: 00010002 CPU: 0 EIP is at vbus_enet_tx_start+0xfc/0x373 [vbus_enet] EAX: c0c49118 EBX: f50c1900 ECX: c0c49118 EDX: 966394d5 ESI: 00000000 EDI: 00000001 EBP: c1581b8c ESP: c15819dc DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Process swapper (pid: 0, ti=c1580000 task=c1586e60 task.ti=c1580000) Stack: 00000246 00000000 f6143000 f6143340 f6330980 c0c48024 00000087 c0c49118 <0> c1581a3d c1d7d1e2 00000202 00000062 00000000 00000000 00000000 00000000 <0> 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 Call Trace: [<c10437e8>] ?

This makes it much easier to distinguish the alacrity kernel from other kernels.

We currently try to generate an EVQ::LINKSTATE event regardless of the actual state of the EVQ. This can cause a host side oops when the guest does not enable EVQ.
