Re: how to hack the sk_buff memory

["Peter Teoh" <htmldeveloper@xxxxxxxxx>]

The whole net code is highly optimized - in the sense that it is
copied between different parts of the memory only twice - according to
"Linux Network Internals" - all the way to userspace (correct? if i
did not remember wrongly :-)).   And if you want to intercept, many
ways.   One is to intercept right after the packets is received from
the network card, which is the function net_rx_action(), and just
before sending is net_tx_action().
Above that the packet will be reassembled/disassembled according to
network protocols.
Have fun.
