[Bluez-users] Driver version problems..hci_usb & bluetooth parser

[Bluez-users] Driver version problems..hci_usb & bluetooth parser

[benbouzid imad]

Hi,

I work with 2.6.10-1.766_FC3 kernel. 
I rebuilt bluetooth.ko and hci_usb.ko using using
those makefile:
---------------------------------
#
# Makefile for bluetooth.ko
#

obj-m	+= bluetooth.o
bluetooth-objs := af_bluetooth.o hci_core.o hci_conn.o
hci_event.o hci_sock.o hci_sysfs.o lib.o

KDIR	:= /lib/modules/$(shell uname -r)/build
PWD	:= $(shell pwd)
default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
----------------------------------
#
# Makefile for the Linux Bluetooth HCI device drivers.
#

obj-m	:= hci_usb.o

KDIR	:= /lib/modules/$(shell uname -r)/build
PWD	:= $(shell pwd)

default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
------------------------------------- 


but with this I used bluetooth files of 2.6.8 kernel.
and before building modules I changed in
/lib/modules/2.6.10-1.766_FC3/build/include/net
the bluetooth directory by the 2.6.8 kernel one.

until know everyting is okay and is not blutooth
specific.

The copilation is okay, and I put my too modules in
the specific directories in
/lib/modules/2.6.10-1.766_FC3/kernel

Any bluez module at this time is loaded.
and when I run
#modprobe bluetooth.ko
i can see my module with lsmod.
but when I run
#modprobe hci_usb.ko
I had:

FATAL: Error inserting hci_usb
(/lib/modules/2.6.10-1.766_FC3/kernel/drivers/bluetooth/hci_usb.ko):
Unknown symbol in module, or unknown parameter (see
dmesg)

and I see with dmesg:
Bluetooth: Core ver 2.6
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager
initialized
Bluetooth: HCI socket layer initialized
hci_usb: disagrees about version of symbol
hci_free_dev
hci_usb: Unknown symbol hci_free_dev
hci_usb: disagrees about version of symbol
hci_alloc_dev
hci_usb: Unknown symbol hci_alloc_dev
hci_usb: disagrees about version of symbol
hci_unregister_dev
hci_usb: Unknown symbol hci_unregister_dev
hci_usb: disagrees about version of symbol
hci_register_dev
hci_usb: Unknown symbol hci_register_dev

hci_free_dev,...etc are defined in hci_core.h

bluetooth.ko use hci_core.c and hci_usb.c includes
hci_core.h
and If review what I deed I use thes same version of
Hci_core for my too modulues. 
so I don't undersand why there is a misunderstanding
between the too modules?

regards

use either the Fedora Core kernel or the vanilla one. Don't try to play
tricks and then complain that it does not work.

Marcel

Re: [Bluez-users] Driver version problems..hci_usb & bluetooth parser

[benbouzid imad]

when I tape
#modprobe -f hci_usb
it works, I can do an hciconfig hci0 up  an using
hcitool etc...


dmesg tells:
hci_usb: no version for "struct_module" found: kernel
tainted.
hci_usb: no version magic, tainting kernel.
Bluetooth: HCI USB driver ver 2.7 
usbcore: registered new driver hci_usb 

I don't understand where is the matter. But is it
possible that HCI USB driver is a ver 2.7 and the
Bluetooth: Core ver 2.6 in the same kernel?

this is no problem. All modules have there own version number.

Hi!

Try google or some other great magic tool ;-)
Seems to me that the kernel image was not compiled from
exactly the same sources.
IMHO it's better to compile a complete new kernel and not
only some modules and try to load them into the
distribution kernel (this is just my guess about what might
be the problem so please complain if I'm wrong)

Best regards,
Sebastian
