Package: smbnetfs
Version: 0.6.1-1
Severity: important

At least since 0.6.0, any attempt to use open(2) with O_CREAT on a mounted smb
filesystem fails with EIO (Input/output error). The file is created, with has a
size of 0.

This is a call caused by "cp" traced with strace:

 openat(AT_FDCWD, "/home/ydelia/shared/file", O_WRONLY|O_CREAT|O_EXCL, 0644) = 
-1 EIO (Input/output error)

This is what is outputed by smbnetfs with debugging enabled:

unique: 8, opcode: CREATE (35), nodeid: 5, insize: 62, pid: 4235
create flags: 0x80c1 /server/test/file 0100644 umask=0022
  create[139858764895120] flags: 0x80c1 /server/test/empty

  release[139858764895120] flags: 0x80c1
     unique: 8, error: -5 (Input/output error), outsize: 16

So it seems that smbnetfs creates the file correctly, then attempts an fstat
and stops there.
