[Bug 9607] New: Wine causes process hang in kernel when running applications from FAT partition

http://bugs.winehq.org/show_bug.cgi?id=9607

Summary: Wine causes process hang in kernel when running
                    applications from FAT partition
           Product: Wine
           Version: 0.9.39.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Distro: Kubuntu Dapper 6.06
Wine: 0.9.9-0ubuntu2 (tested also with 0.9.39 from winehq.org)
Kernel: 2.6.15-29-386 (2.6.15-29.58)

This is kernel bug, but affects only wine, so workaround in wine is easier.

When .exe is run from FAT partition, wine process gets stuck in kernel in "D"
state and cannot be killed.

I have straced the process and it appears it is stuck in:
 ioctl(9, TUNIOCGETINFO or VFAT_IOCTL_READDIR_BOTH
This way user can prevent unmounting FAT partition by running wine on FAT
partition.
To reproduce:
 1. Mount any FAT volume (for example USB pendrive)
 2. Copy some file.exe file to it.
 3. Run: wine /media/mydisk/file.exe
 4. Wine hangs and cannot be killed.

Possible workaround is to recompile wine with "#define VFAT_IOCTL_READDIR_BOTH"
in dlls/ntdll/directory.c commented out.
I have checked that it works.

Invalid right from the gate.

Wine does not support running apps from a FAT partition.

Reporter, upgrade to the latest Wine version (which is wine-0.9.44) and retest.
However you should really upgrade your kernel version.

According to http://wiki.winehq.org/FAQ,%22Does it matter what filesystem I use?"

Wine is written to be file system independent, so MS Windows applications will
install and run under virtually any file system supported by your brand of
UNIX.

Wine already has workarounds for various kernel bugs in VFAT driver, so adding
one more shouldn't hurt IMO.

Re-opening.

Have we talked to the kernel dev for vfat about these problems?

Wine contains hooks which are valid only on FAT partition, like the mentioned
VFAT_IOCTL_READDIR_BOTH ioctl.

I will re-test  on wine 0.44, but from reading the source I am pretty sure it
is the same.

How urgent is this to fix?

Does it e.g. hurt people using "portable apps" on pen drives?
I haven't heard of any complaints from those folks for some reason...

I guess this does not happen in newer kernel version.
Kernel 2.6.15 is though used in Ubuntu 6.06, which is long-term supported
version, so it should be spotted by some people.

I have come across the bug when some other user reported he cannot run
application from his Windows partition (which used FAT), but FAT Windows
partitions are rare this time.

If this particular bug is fixed newer kernels, can we just resolve this invalid
then? It's not a wine bug.

If you want this fixed in ubuntu LTS, you should file a bug report there. That
seems reasonable enough.

I don't know if it is fixed in newer kernel versions. If it is, I guess you
should close the bug.

I have sucessfuly started several programs from a pen-drive on my 2.6.20-16
kernel from Ubuntu 7.04 and then unmounted the drive. Do you have this problem
with every executable you try to run or only certain directories or executables
triggers the bug? Can you create a small FAT image (let's say no more than
360kB) that triggers it and attach it (compressed) to this bug?

I ran into this bug with wine 1.0-rc1 and Picasa on a machine running Ubuntu
Dapper. Picasa scanned a USB drive and hung on the ioctl call.

I'll test on more machines when I get a chance. Reopening.

This is a kernel bug only found in Ubuntu Dapper 2.6.15-28 and up, due to a
copy and paste error in the Ubuntu specific patches. Fortunately it's an
one-liner so hopefully Ubuntu will push out a new update soon.

FYI, the one liner patch has been committed into Ubuntu. A linux kernel with
version > 2.6.15-52.71 should be available for Dapper in the near future.
