This can be broken down into these major areas: - Documentation updates (language translations and fixes, as well as kobject and kset documenatation updates.) - major kset/kobject/ktype rework and fixes. This cleans up the kset and kobject and ktype relationship and architecture, making sense of things now, and good documenation and samples are provided for others to use. Also the attributes for kobjects are much easier to handle now. This cleaned up a LOT of code all through the kernel, making kobjects easier to use if you want to. - struct bus_type has been reworked to now handle the lifetime rules properly, as the kobject is properly dynamic. - struct driver has also been reworked, and now the lifetime issues are resolved. - the block subsystem has been converted to use struct device now, and not "raw" kobjects. This patch has been in the -mm tree for over a year now, and finally all the issues are worked out with it. Older distros now properly work with new kernels, and no userspace updates are needed at all. - nozomi driver is added. This has also been in -mm for a long time, and many people have asked for it to go in. It is now in good enough shape to do so. - lots of class_device conversions to use struct device instead. The tree is almost all cleaned up now, only SCSI and IB is the remaining code to fix up... * git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (196 commits) Driver core: coding style fixes Kobject: fix coding style issues in kobject c files Kobject: fix coding style issues in kobject.h Driver core: fix coding style issues in device.h spi: use class iteration api scsi: use class iteration api rtc: use class iteration api power supply : use class iteration api ieee1394: use class iteration api Driver Core: add class iteration api Driver core: Cleanup get_device_parent() in device_add() and device_move() UIO: constify function pointer tables Driver Core: constify the name passed to platform_device_register_simple driver core: fix build with SYSFS=n sysfs: make SYSFS_DEPRECATED depend on SYSFS Driver core: use LIST_HEAD instead of call to INIT_LIST_HEAD in __init kobject: add sample code for how to use ksets/ktypes/kobjects kobject: add sample code for how to use kobjects in a simple manner. kobject: update the kobject/kset documentation kobject: remove old, outdated documentation. ...

fix oops on rmmod capidrv

Fix overwriting the stack with the version string (it is currently 10 bytes + zero) when unloading the capidrv module. Safeguard against overwriting it should the version string grow in the future.

[ISDN] capidrv: address two longstanding warnings

2007-10-29T08:45:06Z

* change #warning to a code comment * add comment and special ifdef'd 64-bit code for a situation where we must store a pointer into a CAPI field 'Data', which is fixed by the interface at 32 bits. Signed-off-by: Jeff Garzik Acked-by: Karsten Keil

isdn: guard against a potential NULL pointer dereference in old_capi_manufacturer()

2007-10-16T16:43:10Z

In drivers/isdn/capi/kcapi.c::old_capi_manufacturer(), if the call to get_capi_ctr_by_nr(ldef.contr); in line 823 returns NULL, then we'll be dereferencing a NULL pointer in the very next line.

fix possible NULL deref on low memory condition in capidrv.c::send_message()

2007-10-16T16:43:10Z

If we fail to allocate an skb in drivers/isdn/capi/capidrv.c::send_message(), then we'll end up dereferencing a NULL pointer. Since out of memory conditions are not unheard of, I believe it is better to print a error message and just return rather than bring down the whole kernel. Sure, doing this may upset some application, but that's still better than crashing the whole system.

isdn/capi warning fixes

2007-07-17T17:23:06Z

drivers/isdn/capi/capi.c: In function 'handle_minor_send': drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of different size Of course, the code here might actually be buggy, in which case this patch should not be applied? Answer: No this field is ignored inside linux kernel.Yes this is ugly, but it's the CAPI spec for all OS. CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which represent the 32 bit buffer address of the payload data. In linux the payload data do not use a sperate buffer, data follows directely after the CAPI Message in the same skb and we use this assumption inside the drivers, so we can ignore this field. Inside the linux CAPI implemetation we never use this field, so it could also have no value, but since random data in a message is bad as well (e.g. displayed in CAPI traces) we set is to the most adequate value. Outside the kernel the capi20 library sets the correct addresses (there is an optional second field for 64 bit adresses for 64 bit systems, we do not use here).
