Public bug reported:
Binary package hint: linux-wlan-ng
I compiled linux-wlan-ng from the svn repository.
It produced segfaults after loading the module prism2_usb.
I changes following file:
src/p80211/p80211netdev.c
in function wlan_setup:
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,28) )
dev = alloc_netdev(0,"wlan%d",ether_setup);
#else
dev = kmalloc(sizeof(netdevice_t), GFP_ATOMIC);
#endif
if ( dev == NULL ) {
WLAN_LOG_ERROR("Failed to alloc netdev.\n");
result = 1;
} else {
#if (LINUX_VERSION_CODE < KERNEL_VERSION(2,6,28) )
memset( dev, 0, sizeof(netdevice_t));
ether_setup(dev);
#endif
.....
if (dev->_tx == NULL) {
WLAN_LOG_ERROR("null pointer netif_stop_queue\n");
result = 1;
}
else {
netif_stop_queue(dev);
}
