<font face="courier new,monospace">HI Friends,<br>Trying to Play with Net-Filter Hooks and here are my Queries!<br><br>1] While adding a New UDP/IP Header over the received skbuffer from NetFilter Module;need to fill the UDP Check-sum. Please let me know ; if there is any Kernel Function which we can use to do this Job ??? OR Do I need to write our own Function to calculate the Check-sum ???<br clear="all">
<br>2] Once after adding New Headers to the received skbuffer ; am trying to return NF_ACCEPT. My Understanding was that ; the newly expanded skbuffer with added Headers will be again taken my Net-Filter Hooks Module and will deliver back to the net device. rt? OR Was there some thing more that I should do ; to send the new skbuffer to the device ??<br>
<br>Looking forward for the reply !!<br><br>-Thanks in Advance,<br></font><font style="font-family:courier new,monospace" size="2">VKS</font><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace"></span><br>
