hi doug,
  thank you very much , wlan_ccmp.o is also a gpl and bsd license module, 

MODULE_LICENSE("Duak BSD/GPL");

I change MODULE_LICENSE("Duak BSD/GPL") to MODULE_LICENSE("GPL") in source codes ,but the same problem is present.

                         advan

This means that the symbols were exported with
EXPORT_SYMBOL_GPL(...).  See

http://ussg.iu.edu/hypermail/linux/kernel/0110.2/0369.html

for an excellent description.  Is wlan_ccmp a GPL'd
module.  If not, wlan_ccmp is not allowed to use
symbols crypto_alloc_tfm and crytpo_free_tfm.

Regards,
...doug
