device create: char: convert device_create_drvdata to device_create

2008-10-16T16:24:42+00:00

Now that device_create() has been audited, rename things back to the
original call to be sane.

device create: char: convert device_create to device_create_drvdata

2008-07-22T04:54:41+00:00

device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.

raw: BKL pushdown

Put explicit lock_kernel() calls into raw_open(), even though the existing
locking looks adequate.

cdev: remove unneeded setting of cdev names

2007-10-12T21:51:02+00:00

struct cdev does not need the kobject name to be set, as it is never
used.  This patch fixes up the few places it is set.

[PATCH] raw: don't allow the creation of a raw device with minor number 0

2007-02-11T18:51:34+00:00

Minor number 0 (under the raw major) is reserved for the rawctl device
file, which is used to query, set, and unset raw device bindings.  However,
the ioctl interface does not protect the user from specifying a raw device
with minor number 0:

$ sudo ./raw /dev/raw/raw0 /dev/VolGroup00/swap
/dev/raw/raw0:  bound to major 253, minor 2
$ ls -l /dev/rawctl
ls: /dev/rawctl: No such file or directory
$ ls -l /dev/raw/raw0
crw------- 1 root root 162, 0 Jan 12 10:51 /dev/raw/raw0
$ sudo ./raw -qa
Cannot open master raw device '/dev/rawctl' (No such file or directory)

As you can see, this prevents any further raw operations from
succeeding.  The fix (from Steve Fernandez) is quite simple--do not
allow the allocation of minor number 0.
