Hello sir,
I am using madwifi v1.5 driver with linksys pci
adapter.
I have written a lsm hook for netif_rx(struct sk_buff
*skb) in security.h file.
I have called that hook from netif_rx fuction (after
variable declaration) in net/core/dev.c .
Then I have written module for that hook.In that
module, I have dropped Icmp packets. But in Wireless
network ,When i ping machine "B" from machine "A" ,i
am getting the message on console like this
64 bytes from machine "B" ip addr :icmp_seq=no
......
but this should not happen because i am dropping
incoming Icmp packets in my module.
Can you tell me why this is happening.What i have made
wrong .
Note : 1)My module is working proper and i have
also
freed the skb buffer.
2)It work fine for wired network.
3)Ethereal shows the correct result (does not
capture ICMP reply packets)
for both wired and wireless network.
-Plz help me.We are trying
this from 6 days .
thanks in advance
-Rishi
