Most recent kernel where this bug did not occur: 2.6.18.1 Distribution: Gentoo Linux Hardware Environment: Intel Pentium M, i915M Laptop Software Environment: GNU, nbd userspace tools 2.8.6 (on server and client which are on distinct hardware) Problem Description: When using a network block device with heavy IO (reads and writes) either the process(es) doing IO end up in disk-wait state or kernel panics with null-pointer/page-fault. Dead-locks happen either with debugging output enabled for nbd or playing with scroll-lock on the process doing IO. ============ debug kprint output from nbd (2.6.18.1) ===================== [ 245.424000] nbd0: request f693d4f8: dequeued (flags=944) [ 245.428000] nbd0: request f693d4f8: sending control (read@1646915584,4096B) [ 245.432000] nbd0: request f693d4f8: got reply [ 245.436000] nbd0: request f693d4f8: got 4096 bytes data [ 245.440000] nbd0: request f693d4f8: done [ 245.444000] nbd0: request f693d4f8: dequeued (flags=944) [ 245.448000] nbd0: request f693d4f8: sending control (read@2209558528,4096B) [ 245.452000] nbd0: request f693d4f8: got reply [ 245.456000] nbd0: request f693d4f8: got 4096 bytes data [ 245.460000] nbd0: request f693d4f8: done [ 245.464000] nbd0: request f693d59c: dequeued (flags=944) [ 245.468000] nbd0: request f693d59c: sending control (read@2760994816,4096B) [ 245.472000] nbd0: request f693d4f8: dequeued (flags=4000945) [ 245.476000] nbd0: request f693d4f8: sending control (write@2155683328,3584B) [ 245.480000] nbd0: request f693d59c: got reply [ 245.484000] nbd0: request f693d59c: got 4096 bytes data [ 245.488000] nbd0: request f693d59c: done [ 245.492000] nbd0: request f693d4f8: sending 3584 bytes data [ 245.496000] nbd0: request f693d4f8: got reply [ 245.500000] nbd0: request f693d4f8: done ============== end of debug kprint output from nbd ================ The last line from output above is the last message generated by nbd before processes went into disk-wait.

Oh wonderful. The call trace is garbage because the kernel oopsed while trying to generate the call trace. Can you please try 2.6.19-rc2 (or at least 2.6.18, but 2.6.19-rc2 has more fixes) and also disable CONFIG_UNWIND_INFO? Hopefully that'll get us a decent backtrace. Also the backtraces you've included here got wordwrapped, which makes them hard to read. Thanks.
With 2.6.18.1 I have troubles getting stacktrace, there netconsole stops working "just before" kernel panics and outputs dumps to screen. From netconsole I get output of normal printk(), but no more from the stack-traces which are at least two 0x31A screens high. Serial console is not possible as I have no serial port on that host and no nullmodem cable either (for use with usb2serial). With 2.6.18.1 in most cases I get no output at all, only with pushing all output to console (dmesg -n 8) I get some stacktrace. Otherwise it's like a deadlock, sysrq is not answering either in that state. Regarding 2.6.19-rc2 I will try to reproduce there as well and report back! Here is one trace that it accepted to send via netconsole: [ 275.396000] BUG: unable to handle kernel paging request at virtual address 8bec5593 [ 275.400000] BUG: unable to handle kernel paging

I tried 2.6.19-rc2 as well, same kind of crash with page-fault.

Hope this helps figuring out what's happening. From memory point of view, system has 2GB and has plenty of unused memory (fresh start in console mode only) dd if=/dev/ndb0 of=/dev/null works without an issue, copying lots of files to empty partition on nbd0 worked fine, just (intense) mixed read/write access seems to cause trouble.
Have you tried setting CONFIG_4KSTACKS=n?

You're right, without 4k stacks it works. Looks like nbd description should at least have a warning regarding 4K stacks, or nbd would need an own stack in case of 4k stacks (possibly the way loop does)

Created attachment 9358 [details] alt + sysreq + t output Unfrtuately the stack-overflows with 4k stacks are not the only troubles I experience with nbd... For now I've disabled 4k Stack but kept preemption (with preemptible big kernel lock) and regularly get heavy-io processes accessing my nbd device ending up in D state. Attached is the output of sysreq+t in such a locked state (with minimum of processes around) Most intresting are probably the following tasks: pdflush (PID 160) ebuild.sh (PID 20785) Both seem to be blocked by some XFS spinlock/mutex. ebuild.sh is a bash process doing some parsing for the Gentoo emerge (calculating dependencies for system update with empty cache) That call of emerge (like explicit metadata updates) produces a lot of disc activity on the cache (ndb in my case) and the portage tree (squashfs in my case). The probably important point is that there are lots of reads AND writes happening. Just reading or just writing never caused such deadlocks. This problem can be reproduced very easily. My setup: 2.6.18.1 kernel, based on config posted above (only limited changes) The kernel running at that time is patched with linux-vserver 2.1.1-rc42 and squashfs 3.1 CPU: PentiumM second generation (Family 6, model 13, steppting 8) RAM: 2GB GCC 3.4.6 + glibc 2.3.6 used to compile kernel + userspace GCC 4.1.1 + glibc 2.4-r3 used to compile userspace in chroot/context running emerge (PIDs: 9501, 9530, 9547, 20784, 20785) I will try to reproduce with vanilla 2.6.18.1 and 2.6.19-rc3, to be sure that linux-vserver does not interfere, and report back. If more specific information is useful, please indicate what information I should provide!
Created attachment 9364 [details] alt + sysreq + t output on vanila 2.6.18.1 Did similar working with vanilla 2.6.18.1 kernel and still get processes on NBD (XFS partition) to deadlock. This time stuck while doing a rm -rf. Using 2.6.19-rc3 I have not yet been able to reproduce these locks... maybe fixed by one of the XFS changes?...
Created attachment 9370 [details] alt + sysreq + t output on vanila 2.6.19-rc3 Also got it with vanilla 2.6.19-rc3, but it happens less often / less immediately... The output from kernel.log for this dead-lock contains two alt+sysReq+t, the second issued about 6 minutes after the first (no reboot in between, just umounting some other filesystems / flushing buffers on other block devices) The weird thing is that I never get such deadlocks with XFS on other blockdevices (loop, sd/usb-storage, local drive)...

See http://bugzilla.kernel.org/show_bug.cgi?id=7364 This guy has XFS deadlocks. And stack overruns, but we knew about that. Perhaps the deadlocks are due to NBD?

The first set of traces show: - pdflush trying to write the superblock and sleeping because the superblock buffer is pinned in memory. - a create waiting for the superblock buffer lock so it can include the superblock in a transaction The create is backed up behind superblock write, but hte superblock write can't make progress until the the pinned buffer is unpinned during I/O completion of the log buffer that contains the transaction that the superblock modification was recorded in. So it would appear we are hung up waiting for I/O to complete. And in the 2.6.18.1 trace we have: - rm doing an inode read from disk which is waiting for I/O completion. - pdflush trying to write the superblock and sleeping because the superblock buffer is pinned in memory. If the inode read wasn't a give-away, the pdflush thread should make it is obvious we are hung up waiting for I/O completion. And from 2.6.19-rc3, we have a pdflush thread asleep in xlog_state_get_iclog_space() waiting for a in-core log buffer to become available so it can commit an allocation transaction to the log. We only wait here when all the iclog buffers are under I/O and we have to wait for them to complete their I/O..... So, there's no deadlocks in XFS here - XFs is simply waiting for the I/O it issued to complete. I think this pretty clearly indicates an NBD problem. Cheers, Dave.

The only process that's in nbd code is the nbd-client, which is doing what it normally does: sitting and waiting for replies from the server. Any details about what was going on at the time of the deadlock? -- Paul
Bruno, Could you please give some more info on your application and setup. Also, have you tried the latest kernel again for the record? Thanks.

/dev/nbd0 I link an image of an XFS / filesystem (also Gentoo) and chroot into the mountpoint to run emerge --metadata (update of metadata with lots of I/O, reading and writing portage tree metadata) * nbd server Gentoo Linux, gcc 4.1.2, glibc 2.5, nbd 2.9.3 It exports the file-based image of that root filesystem Both machines are on the same subnet, after the BUG() messages in kernel log the emerge process is blocked in D state, no traffic pending on nbd connection on either side according to netstat. Filesystem is still working for other processes (e.g. listing files) and show network traffic.
Please verify against a modern kernel as XFS went on a stack diet
