Windows Server 2003: stack overflow


In this case Windows Server 2003 was crashing during boot.

kd> vertarget
Windows Server 2003 Kernel Version 3790 (Service Pack 2) UP Free x86 compatible
Product: LanManNt, suite: TerminalServer SingleUserTS
Built by: 3790.srv03_sp2_qfe.150316-2035

As always a good start to analyze a crash dump is the !analyze command.

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 00000008, EXCEPTION_DOUBLE_FAULT
Arg2: 80042000
Arg3: 00000000
Arg4: 00000000

The !analyze output indicates that this crash the result of stack overflow and suggests us to use the !stackusage command to investigate stack usage. So, let's follow the instructions that the debugger is giving us.

It would be easy to blame NTFS since it is the top stack consumer, but instead let's find out what drivers are making calls into NTFS to access data. We can see from above that the rest of the stack is not complete. It's because third party drivers were compiled with FPO optimisation turned on. So, I reconstructed the stack manually.

As we can see there is only one call that is accessing some data and the result of this call is that about half of the stack was consumed.

kd> ? b7953784-b7952000
Evaluate expression: 6020 = 00001784

kd> ? b7955000-b7953784
Evaluate expression: 6268 = 0000187c

Let's find out the name of the file. We know that the third parameter to the ZwCreateFile function is a pointer to an OBJECT_ATTRIBUTES structure that specifies the object name.

kd> dps b7953784 L5
b7953784  00080286
b7953788  b8572ab9 nv4_mini!nvDumpConfig+0x1e1b29
b795378c  b79537d8
b7953790  80100000
b7953794  88ad4db4

kd> dt nt!_OBJECT_ATTRIBUTES 88ad4db4
   +0x000 Length           : 0x18
   +0x004 RootDirectory    : (null) 
   +0x008 ObjectName       : 0xb79539c8 _UNICODE_STRING "\SystemRoot\system32\nvdrssel.bin"
   +0x00c Attributes       : 0x240
   +0x010 SecurityDescriptor : (null) 
   +0x014 SecurityQualityOfService : (null)

So, to lower the stack consumption and to stop its overflow, I recommended to rename the nvdrssel.bin file. When it was done, the server came back to life.
