Hopefully, you recieved an email about this last November, but this
is a follow up because the bug is still there.
Smatch complains about a buffer overflow in this:
drivers/scsi/csiostor/csio_rnode.c:872 csio_rnode_fwevt_handler()
error: buffer overflow '(rn)-stats.n_evt_fw' 22 = 26
This series regards the whitelist that is used for the SG_IO ioctl. This
whitelist has three problems:
* the bitmap of allowed commands is designed for MMC devices (roughly,
play/burn CDs without requiring root) but some opcodes overlap across SCSI
device classes and have different meanings
Scanners allow all commands because vendor-specific commands are common.
The queue flag we just added lets us keep this behavior by default,
while making it possible to disable it.

Some defines and structs remained when support was removed for SG_IO
filters in sysfs. Remove them.

This queue flag will let unprivileged users send any SG_IO command to
the device, without any filtering.
This is useful for virtualization, where some trusted guests would like
to send commands such as persistent reservations, but still the virtual
machine monitor should run with restricted

Only commands that affect the medium are added. Commands that affect

Some SCSI commands can be sent to disks via SG_IO even by unprivileged
users. Unfortunately, some opcodes overlap across SCSI device classes
and have different meanings for different classes. Four of them can
be used for read-only file descriptors on MMC, but should be limited to
descriptors
Tapes have no problematic overlap, but quite a few commands
are missing that are useful when operating tapes with /dev/sg.
This patch adds them.
START STOP UNIT, FORMAT UNIT and SEEK(10) have similar meanings
but different names for tapes, so move them to the tape section
of the whitelist.

Besides CD-ROMs, three more device types are interesting for SG_IO:
media changers, tapes and of course disks.
Starting with this patch, we will whitelist a few more commands for
these devices. For media changers, enable INITIALIZE ELEMENT STATUS
and REQUEST VOLUME ELEMENT ADDRESS. A few
Three MMC commands were never included: PLAY AUDIO(12), SERVICE ACTION

not been obsoleted in recent versions of the standard.

Store the filters in a 256-entry array, and pick an appropriate filter
for SCSI devices. Apart from SCSI disks, SG_IO is supported for CCISS,
ide-floppy and virtio-blk devices; TYPE_DISK (which is zero, i.e. the
default) is more appropriate for these devices than TYPE_ROM.

To prepare for the next patches, reorganize the list of commands into
a two-way table of command numbers and device types.
One command (READ CAPACITY) was listed twice in the old table, hence
the new table has one entry less than the old one.
Right now, there is still just one bitmap and the
