* [PANIC, hyperv] BUG: unable to handle kernel paging request at ffff880077800004 (hv_ringbuffer_write) @ 2014-08-20 9:26 Sitsofe Wheeler 2014-08-20 11:15 ` Dexuan Cui 2014-08-25 14:02 ` Dexuan Cui 0 siblings, 2 replies; 24+ messages in thread From: Sitsofe Wheeler @ 2014-08-20 9:26 UTC (permalink / raw) To: Dexuan Cui Cc: K. Y. Srinivasan, Greg Kroah-Hartman, Haiyang Zhang, devel, linux-kernel, Jean-Christophe Plagniol-Villard, linux-fbdev While booting a Hyper-V 3.17.0-rc1 guest on a 2012 R2 host a BUG was triggered while registering hyperv_fb which in turn caused a panic. Various kernel debugging options (CONFIG_DEBUG_PAGEALLOC, CONFIG_SLUB_DEBUG=y...) were on at the time. This only seems to happen if the guest is being booted with only one CPU allocated to it.

I suppose you're using the latest mainline v3.17-rc1(7d1311b9). Can you please attach your kernel config file so that I can try to reproduce the issue more easily? Do you mean the issue only happens to UP guest and doesn't happen to SMP guest? Thanks, -- Dexuan ^ permalink raw reply [flat|nested] 24+ messages in thread

You're welcome! > I suppose you're using the latest mainline v3.17-rc1(7d1311b9). That's right - Linux 3.17-rc1 (7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9). > Can you please attach your kernel config file so that I can try to reproduce > the issue more easily? Sure (it's pretty much the same one mentioned in https://lkml.org/lkml/2014/8/19/101 and https://lkml.org/lkml/2014/8/19/708 but those don't seem framebuffer related) but just in case I'll attach it to this mail. > Do you mean the issue only happens to UP guest and doesn't happen to > SMP guest? Yes - if in Windows I go to Hyper-V Manager, press the right mouse button over the guest and go to Settings..., click on Processor at the left and set the Number of virtual processors to 1 on the right then this issue occurs. If the number is greater than 1 then this does not seem to occur. -- Sitsofe | http://sucs.org/~sits/ [-- Attachment #2: kconfig-hv-3.17-debug --] [-- Type: text/plain, Size: 84110 bytes --] # # Automatically generated file; DO NOT EDIT. #

This sounds very fishy as if network setup has left things in a bad state. What is baffles me is the whole UP vs SMP thing - why would UP make this show up consistently? Perhaps some assertions could be added to check that rbi->ring_buffer still has sane values in it after operations on it are finished? I guess you could try switching things around and using kmemcheck (https://www.kernel.org/doc/Documentation/kmemcheck.txt ). If the whole area close to rbi->ring_buffer->read_index is being stomped on it should show up. If it's just being set to a duff value or freed that going to be harder to track down although poisoning before freeing should allow us to distinguish that case... >From your analysis this doesn't sound framebuffer related - perhaps we could drop the linuxfb CC's on these mails going forward? -- Sitsofe | http://sucs.org/~sits/ ^ permalink raw reply [flat|nested] 24+ messages in thread

IMO it has nothing to do with the hyperv netvsc, as here hypervfb is the first one to invoke vmbus_open(), and hyperv netvsc's vmbus_open() hasn't been invoked. > This sounds very fishy as if network setup has left things in a bad > state. Ditto. I doubt the network driver causes the issue. > What is baffles me is the whole UP vs SMP thing - why would UP > make this show up consistently?

With more tests, I found vcpus=2 has the same issue, despite a small possibility. vcpus=4 seems fine in my limited tests. > I guess you could try switching things around and using > kmemcheck (https://www.kernel.org/doc/Documentation/kmemcheck.txt ). > If > the whole area close to rbi->ring_buffer->read_index is being stomped on > it should show up.

Actually I found the direct cause of the panic: sometimes vmbus_post_msg() can return 4 (HV_STATUS_INVALID_ALIGNMENT), but vmbus_open() doesn't propagate this error to the caller synthvid_connect_vsp(), and vmbus_open() " goto error1" and frees the ringbuffer! So later the access to ring_buffer->read_index is caught by CONFIG_DEBUG_PAGEALLOC. I don't see any "invalid alignment" here... and I can't explain why vcpus=4 seems OK... Debugging WIP. BTW, please try the attached patch. With it, the VM doesn't panic in my side with vcpus=1 and can boot to shell prompt(looks the boot-up is very slow. I have to wait for several minutes...) > From your analysis this doesn't sound framebuffer related - perhaps we > could drop the linuxfb CC's on these mails going forward? OK.

This is because if the mimetype of the attachment is something like octet/stream then various tools (e.g. https://lkml.org/lkml/2014/8/26/271 and https://patchwork.kernel.org/project/LKML/list/?submitter=100981 ) won't archive/extract the patch... I rebased your patch on top of the K.Y.'s "Drivers: hv: vmbus: Eliminate calls to BUG_ON()" patch set (see below). The combination no longer triggers the bug and it doesn't take too long to boot but the network interface fails to work (which I believe is . Rebased vmbus open fixes patch. --- drivers/hv/channel.c | 4 +++- drivers/hv/connection.c | 2 ++ 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/drivers/hv/channel.c b/drivers/hv/channel.c index c7ffd42..964cdc9 100644 --- a/drivers/hv/channel.c +++ b/drivers/hv/channel.c @@ -165,8 +165,10 @@ int vmbus_open(struct vmbus_channel *newchannel, u32 send_ringbuffer_size, ret = vmbus_post_msg(open_msg, sizeof(struct vmbus_channel_open_channel)); - if (ret != 0) + if (ret != 0) { + err = ret; goto error1; + } t = wait_for_completion_timeout(&open_info->waitevent, 5*HZ); if (t == 0) { diff --git a/drivers/hv/connection.c b/drivers/hv/connection.c index 16c2ccb..17bf48f 100644 --- a/drivers/hv/connection.c +++ b/drivers/hv/connection.c @@ -433,6 +433,7 @@ int vmbus_post_msg(void *buffer, size_t buflen) switch (ret) { case HV_STATUS_INSUFFICIENT_BUFFERS: case -ENOMEM: + WARN(ret, KERN_ERR "ret = %d\n", ret); break; default: return ret; @@ -441,6 +442,7 @@ int vmbus_post_msg(void *buffer, size_t buflen) retries++; msleep(100); } + WARN(ret, KERN_ERR "ret = %d, retries=%d\n", ret, retries); return ret; } -- 1.9.3 Boot dmesg output (there's no line that mentions retries).

First let me thank you guys for looking into this issue. Looking at your dmesg, it looked like storvsc probe failed as Dexuan had seen. Since the failure appears to be alignment related, perhaps we could test with allocating a page all the time (and getting rid of the kmalloc). Sitsofe, here is a patch based on Dexuan's patch. If this works, I will probably minimize failure cases by pre-allocating per-cpu pages for this.: diff --git a/drivers/hv/hv.c b/drivers/hv/hv.c index edfc848..0ca0cba 100644 --- a/drivers/hv/hv.c +++ b/drivers/hv/hv.c @@ -217,25 +217,17 @@ int hv_post_message(union hv_connection_id connection_id, enum hv_message_type message_type, void *payload, size_t payload_size) { - struct aligned_input { - u64 alignment8; - struct hv_input_post_message msg; - }; struct hv_input_post_message *aligned_msg; u16 status; - unsigned long addr; if (payload_size > HV_MESSAGE_PAYLOAD_BYTE_COUNT) return -EMSGSIZE; - addr = (unsigned long)kmalloc(sizeof(struct aligned_input), GFP_ATOMIC); - if (!addr) + aligned_msg = (struct hv_input_post_message *)get_zeroed_page(GFP_ATOMIC); + if (!aligned_msg) return -ENOMEM; - aligned_msg = (struct hv_input_post_message *) - (ALIGN(addr, HV_HYPERCALL_PARAM_ALIGN)); - aligned_msg->connectionid = connection_id; aligned_msg->message_type = message_type; aligned_msg->payload_size = payload_size; @@ -244,7 +236,7 @@ int hv_post_message(union hv_connection_id connection_id, status = do_hypercall(HVCALL_POST_MESSAGE, aligned_msg, NULL) & 0xFFFF; - kfree((void *)addr); + free_page((unsigned long)aligned_msg); return status; } -- 1.7.4.1 ^ permalink raw reply related [flat|nested] 24+ messages in thread

That is good to hear. I was under the impression that this issue would be resolved with all the cleanup we have done. The last patch-set I posted earlier today has the fix for vmbus_open bug that Dexuan had identified. If you could try with the BUG_ON elimination patch-set I sent out earlier today with the fix in hv.c that I had sent that would be great. > > How come previous alignment efforts weren't working out? I have chosen to always allocate a page and so alignment won't be an issue. I want to eliminate failure in this path and so, I will most likely do a per-cpu pre-allocation of this buffer.

This always-use-page-allocation patch of KY works for me too. :-) > > The only issue seen on boot now is similar to > > https://lkml.org/lkml/2014/8/19/227 ... Hi Sitsofe, I don't see this issue. Do you still see the issue for EVERY boot after you applied KY's always-use-page-allocation patch? I doubt that because in the log of the above link: [ 34.628072] hv_netvsc vmbus_0_15: net device safe to remove [ 34.676573] hv_netvsc: hv_netvsc channel opened successfully [ 34.860292] hv_netvsc vmbus_0_15 eth1: unable to establish send buffer's gpadl [ 34.948983] hv_netvsc vmbus_0_15 eth1: unable to connect to NetVSP - 4 Here the 4 is just HV_STATUS_INVALID_ALIGNMENT -- it should be fixed by the patch. > > That is good to hear.

I'm not sure. If we trust the hypervisor, I would guess in hv_post_message() 1) We'd better add "aligned_msg->reserved = 0;" 2) Should we make sure "aligned_msg->payload_size % 8 == 0"? IMO aligned_msg->payload is an array of 8-byte. > I have chosen to always allocate a page and so alignment won't be > an issue.

Hi Sitsofe, This seems a hv_netvsc specific issue(?) IMO it's better to open a new thread. However, I tried vcpus=1, 2 and 4 for 5 times respectively but couldn't reproduce the same issue(surely I used all of KY's patches, including the page-aligned-input-parameter-for-hypercall one) I used a workload of dd-ing and scp-ing big files. > > > > How come previous alignment efforts weren't working out? > > I'm not sure. > > If we trust the hypervisor, I would guess in hv_post_message() > > 1) We'd better add "aligned_msg->reserved = 0;" > > 2) Should we make sure "aligned_msg->payload_size % 8 == 0"?

If so wouldn't its start have had to be > misaligned? I found in some normal code path, e.g., vmbus_open() -> vmbus_post_msg() -> ... (here the payload size is sizeof(struct vmbus_channel_open_channel), i.e., 148, not a multiple of 8), the payload_size is not a multiple of 8. I don't think this causes the issue here, but I think we'd better double check this and see if there is a potential issue or not.

The config that was posted earlier was an x86_64 config and on that system then the pointers from kmalloc() should already be aligned correctly at sizeof(u64). Earlier I said I suspected the code is racy, so possibly changing from kmalloc() to get_zeroed_page() just changes the timing enough so we don't see the race condition. regards, dan carpenter ^ permalink raw reply [flat|nested] 24+ messages in thread
