[PATCH] Fix udev device creation

2006-05-20T22:00:32+00:00

This patch corrects the order of the calls to register_chrdev() and
pcmcia_register_driver().  Now udev correctly creates userspace device
files /dev/cmmN and /dev/cmxN respectively.

Based on an earlier patch by Jan Niehusmann .

[PATCH] Altix snsc: duplicate kobject fix

2006-05-01T19:03:43+00:00

Fix Altix system controller (snsc) device names to include the slot number
of the blade whose associated system controller is the target of the device
interface.  Including the slot number avoids a problem we're currently
having where slots within the same enclosure are attempting to create
multiple kobjects with identical names.

[PATCH] tipar oops fix

2006-05-01T19:03:42+00:00

If compiled into the kernel, parport_register_driver() is called before the
parport driver has been initalised.

This means that it is expected that tp_count is 0 after the
parport_register_driver() call() - tipar's attach function will not be
called until later during bootup.

[PATCH] cs5535_gpio.c: call cdev_del() during module_exit to unmap kobject references and other cleanups

2006-05-01T19:03:42+00:00

During module unloading, cdev_del() must be called to unmap cdev related
kobject references and other cleanups(such as inode->i_cdev being set to
NULL) which prevents the OOPS upon subsequent loading, usage and unloading
of modules(as seen in the mail thread
http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).

Also, remove unneeded test of gpio_base.

[PATCH] Fix file lookup without ref

2006-04-24T16:56:05+00:00

There are places in the kernel where we look up files in fd tables and
access the file structure without holding refereces to the file.  So, we
need special care to avoid the race between looking up files in the fd
table and tearing down of the file in another CPU.  Otherwise, one might
see a NULL f_dentry or such torn down version of the file.  This patch
fixes those special places where such a race may happen.

[PATCH] Open IPMI BT overflow

2006-04-24T16:56:04+00:00

I was looking into random driver code and found a suspicious looking
memcpy() in drivers/char/ipmi/ipmi_bt_sm.c on 2.6.17-rc1:

	if ((size < 2) || (size > IPMI_MAX_MSG_LENGTH))
		return -1;
	...
	memcpy(bt->write_data + 3, data + 1, size - 1);

where sizeof bt->write_data is IPMI_MAX_MSG_LENGTH.  It looks like the
memcpy would overflow by 2 bytes if size == IPMI_MAX_MSG_LENGTH.  A patch
attached to limit size to (IPMI_MAX_LENGTH - 2).

[PATCH] MPBL0010 driver sysfs permissions wide open

2006-04-17T20:16:04+00:00

The MPBL0010 Telco clock driver (drivers/char/tlclk.c) uses 0222 (anyone
can write) permissions on its writable sysfs entries.  Alter the
permissions to 0220 (owner and group can write).

The use case for this driver is to configure the fail over behavior of the
clock hardware.  That should be done by the more privileged users.

[PATCH] isicom must select FW_LOADER

2006-04-07T16:44:28+00:00

The isicom driver uses request_firmware()
and thus needs to select FW_LOADER.

This patch was already included in Linus' tree.
