Hi All
I want to know which are the evnets
that can lead to the calling of alloc_skb
function which is used to allocate sk_buff.
Arrival and departure of packet are 2 events
which I know. Are there any other events/cases
which can lead to alloc_skb(...) function call in kernel.
Thanks for help
Sushant

Some non-network related drivers use skb's for non-network related
things (ieee1394 is one such abuser).

And some network protocol stacks use it to report events, like
connection requests, etc see the x25 code, for instance
(x25_establish_link, x25_terminate_link), sometimes allocating
1 byte, sometimes using the skb->cb scratch area.
