Bandan Das 83c44b44d4 usb-mtp: change default to success for usb_mtp_update_object
Commit c5ead51f90 (usb-mtp: return incomplete transfer on a lstat
failure) checks if lstat succeeded when updating attributes of a
file. However, it also changed behavior to return an error by
default. This is incorrect because for smaller file sizes, Qemu
will attempt to write the file in one go and there won't be
an object for it.

Daniel P. Berrangé 1259f27ec2 usb-mtp: fix alignment of access of ObjectInfo filename field
The ObjectInfo struct's "filename" field is following a uint8_t
field in a packed struct and thus has bad alignment for a 16-bit
field. Switch the field to to uint8_t and use the helper function
for accessing unaligned 16-bit data.

Note that although the MTP spec specifies big endian, when transported
over the USB protocol, data is little endian.

Daniel P. Berrangé 3541cd48f3 usb-mtp: fix string length for filename when writing metadata
The ObjectInfo 'length' field provides the length of the
wide character string filename. This is then converted to
a multi-byte character string. This may have a different
byte count to the wide character string. We should use the
C string length of the multi-byte string instead.

Daniel P. Berrangé 375cb86d9f usb-mtp: fix bounds check for guest provided filename
The ObjectInfo struct has a variable length array containing the UTF-16
encoded filename. The number of characters of trailing data is given by
the 'length' field in the struct and this must be validated against the
size of the data packet received from the guest.

Since the data is UTF-16, we must convert the byte count we have to a
character count before validating. This must take care to truncate if
a malicious guest sent an odd number of bytes.

Daniel P. Berrangé b4682a63f8 filemon: fix watch IDs to avoid potential wraparound issues
Watch IDs are allocated from incrementing a int counter against
the QFileMonitor object. In very long life QEMU processes with
a huge amount of USB MTP activity creating & deleting directories
it is just about conceivable that the int counter can wrap
around. This would result in incorrect behaviour of the file
monitor watch APIs due to clashing watch IDs.

Instead of trying to detect this situation, this patch changes
the way watch IDs are allocated. It is turned into an int64_t
variable where the high 32 bits are set from the underlying
inotify "int" ID. This gives an ID that is guaranteed unique
for the directory as a whole, and we can rely on the kernel
to enforce this. QFileMonitor then sets the low 32 bits from
a per-directory counter.

The USB MTP device only sets watches on the directory as a
whole, not files within, so there is no risk of guest
triggered wrap around on the low 32 bits.

Bandan Das 4bc1591681 usb-mtp: fix return status of delete
Spotted by Coverity: CID 1399414

mtp delete allows the return status of delete succeeded,
partial_delete or readonly - when none of the objects could be
deleted. Give more meaningful names to return values of the
delete function.

Some initiators recurse over the objects themselves. In that case,
only READ_ONLY can be returned.

Open files and directories with O_NOFOLLOW to avoid symlinks attacks.
While being at it also add O_CLOEXEC.

usb-mtp only handles regular files and directories and ignores
everything else, so users should not see a difference.

Because qemu ignores symlinks, carrying out a successful symlink attack
requires swapping an existing file or directory below rootdir for a
symlink and winning the race against the inotify notification to qemu.

Also, add a "readonly" property which needs to be set to false
for deletion to work.

Bandan Das 5d13ebeacc usb-mtp: print parent path in IN_IGNORED trace fn
Fix a possible null dereference when deleting a folder and
its contents. An ignored event might be received for its contents
after the parent folder is deleted which will return a null object.

Thomas Huth cdab4dc01a usb: Set category and description of the MTP device
It's a storage device, so let's classify it accordingly. And
while we're at it, also add a short description for people who
do not know what MTP means.

Isaac Lozano 67f3ef0c7a usb-mtp: added object properties
Windows uses object properties to determine the size of a file, so to
add object properties, we must also add a minimum set of new commands
and object properties. Most object properties are data that we already
have, except for the unique persistant object identifier. Windows
doesn't use this property, it seems, so we can cheat a bit and just use
the object handle for it.

Isaac Lozano 8a5865f331 usb-mtp: fix sending files larger than 4gb
MTP requires that if a file is larger than 4gb or if sending data larger
than 4gb, that the length field be set to 0xFFFFFFFF.

Also widened a couple variables to prevent overflow errors.

Isaac Lozano 1f66fe5778 usb-mtp: fix usb_mtp_get_device_info so that libmtp on the guest doesn't complain
If an application uses libmtp on the guest system,
it will complain with the warning message:
LIBMTP WARNING: VendorExtensionID: ffffffff
LIBMTP WARNING: VendorExtensionDesc: (null)
LIBMTP WARNING: this typically means the device is PTP (i.e. a camera) but
not a MTP device at all. Trying to continue anyway.

This is because libmtp expects a MTP Vendor Extension ID of 0x00000006 and a
MTP Version of 0x0064. These numbers are taken from Microsoft's MTP Vendor
Extension Identification Message page and are what most physical devices
show.
