Summary: REGRESSION: ReactOS fails to boot in 2nd setup stage in VirtualBox
Key: CORE-14601
URL: https://jira.reactos.org/browse/CORE-14601
Project: Core ReactOS
Issue Type: Bug
Reporter: Illen

ReactOS fails to boot in 2nd setup stage in VirtualBox, it is reproducible only in some host systems. The workarounds are either to disable Intel VT-x or boot with "Debug" option, hence I can't get a debug log, however it fails to boot with the "Screen" option, so I could get a backtrace and attach screenshots. The guilty revision is 0.4.9-dev-766-g6dd27bd. Tested in VirtualBox 5.2.8.

---------------------------------

[~Illen]: I barely see how 0.4.9-dev-766-g6dd27bd could be guilty since this corresponds to a mere commit in cmd.exe which has strictly nothing to do with the bug you encounter. Please verify the few commits before that one.

Illen commented on CORE-14601:
------------------------------

[~hbelusca] That's what I got from other user, he reported that 766 is a guilty revision, but since it is a race condition, he could be wrong. I tested previous commits, and to me, revision 762 definitely is a guilty one.

??get a backtrace and attach screenshots??

Please, attach a screenshot of before you type "bt" too.

??0.4.9-dev-766-g6dd27bd??

I concur with Hermès.
Isn't it only the build you tried?
Which is the last previous build (you tried) that worked?

Also, there were some more Cc commits since that "8 days ago" commit.
Did (not) they fix this issue?

------------------------------

[~Serge Gautherie] It is not fixed in latest builds. I can't take a screenshot before the debugger entrance, everything is erased. The last working build is 0.4.9-dev-761-g2ea6de8.

---------------------------------

By definition, a "guilty revision" is a revision that *introduces* the problem/bug. So it's not just a random revision that exhibits the bug.

Illen commented on CORE-14601:
------------------------------

I'm aware of that. I noticed that the reproducibility depends from the host CPU speed, the faster CPU is, the more chance is that ReactOS will fail to boot. That's why ReactOS could boot up successfully without VT-x (VM works slower without that) or with "Debug" option (ReactOS works slower when debugging is enabled). So anyone who has a fast CPU will experience this issue.

Thomas Faber commented on CORE-14601:
-------------------------------------

Those uniata functions do seem to use a bit more stack than what we saw in the other backtraces. Printing out ebp again could indicate whether that's the problem.

However if, as before, the stack only has one page of stack, it's doomed to fail anyway. So finding out why that happens (are we being called from a WndProc, so win32k already ate up all the stack?) would be key. I'm also not sure why we can't see past KiInterruptTemplateHandler. Perhaps getting a manual stack dump (x esp L 800 or some such) would tell us more.

I still can reproduce the similar issue, however, the reproducibility is much lower than before, and backtrace looks different.

[~Illen], can you try with [^fastfat_stackoverflow.diff]? With it, I cannot reproduce in both QEMU/KVM & VBox.

I've attached the BT with stack and its translation. Beware of rw.c lines are not reliable due to a patch from me there (for StackOverflow ;-)) which is disabled here to allow perfect reproducibility.

Thomas Faber commented on CORE-14601:
-------------------------------------

Okay, disassembly looks as expected, {{mov BYTE PTR [ebp-45],bl}} would indeed access the stack at a lower address than any previous instructions, so would be the point to trigger an overflow.

Stack overflow checking in fastfat makes sense, but I'm not sure whether that would help in this particular case. The call stack looks long, but given what it does it seems relatively minimal. And actually, looking at the stack trace, I don't immediately see any function that uses a lot of stack (I would have expected AtapiStartIo, but that doesn't seem to be too bad).
Anyway, if the check in fastfat works, that's great. If not, the kdbg patch should hopefully tell us where to look for the culprit.

Thanks [~ThFabba], I'll look at applying the KDBG patch.
I also uploaded [^disasm] which contains the disasm of the faulty address. This is at the nearly being of a function.

Thomas Faber commented on CORE-14601:
-------------------------------------

[~Heis Spiter] It does look like it's running out of stack but we'd need to look at the disassembly around uniata.sys:99df to confirm. It doesn't look like an interrupt storm, but it is a deep call stack and I recall some uniata functions using more stack than they should.

It may also be useful to try with some variation of kdbg-print-ebp.patch (first two hunks only I guess) from CORE-11123 to see how much stack space each frame uses.

------------------------------------------

With [^cc_push_lock.diff], I manage to reproduce the issue as well and to get debug to screen ( !qemu_bt1.png|thumbnail! and !qemu_bt2.png|thumbnail! ).
It's interesting in the way that the backtrace seems to be more relevant, we end in uniata interrupts.
I translated the BT (through OCR software, not perfect, sorry).
[~ThFabba], might still come from interrupt storm?

REGRESSION: ReactOS fails to boot in 2nd setup stage in VirtualBox
------------------------------------------------------------------
Key: CORE-14601
URL: https://jira.reactos.org/browse/CORE-14601
Project: Core ReactOS
Issue Type: Bug
Components: Filesystems
Reporter: Illen
Assignee: Bug Zilla
Fix For: 0.4.9
Attachments: VirtualBox_ReactOS_07_05_2018_15_04_39.png, VirtualBox_ReactOS_07_05_2018_15_04_56.png, VirtualBox_ReactOS_10_05_2018_19_08_45.png, backtrace_translated.log, backtrace_translated2.log, backtrace_translated3.log, cc_push_lock.diff, disasm, fastfat_stackoverflow.diff, fastfat_stackoverflow.diff, kvm_translated, kvm_translated, qemu_bt1.png, qemu_bt1.png, qemu_bt2.png, qemu_bt2.png, stack_dump.zip
ReactOS fails to boot in 2nd setup stage in VirtualBox, it is reproducible only in some host systems. The workarounds are either to disable Intel VT-x or boot with "Debug" option, hence I can't get a debug log, however it fails to boot with the "Screen" option, so I could get a backtrace and attach screenshots. The guilty revision is 0.4.9-dev-762-g94ead99. Tested in VirtualBox 5.2.8.

-------------------------------------

Thanks. No excessive stack usage then. We're all within one page of stack again.

Next thing I would try is to manually determine what happens below KiInterruptTemplateHandler by looking at a stack dump. Also, printing out the thread's initial stack and stack limit could be interesting.
