H A D | skbuff.c | be503653 Mon Feb 19 03:51:54 CST 2024 Jeremy Kerr <jk@codeconstruct.com.au> net: mctp: copy skb ext data when fragmenting
[ Upstream commit 1394c1dec1c619a46867ed32791a29695372bff8 ]
If we're fragmenting on local output, the original packet may contain ext data for the MCTP flows. We'll want this in the resulting fragment skbs too.
So, do a skb_ext_copy() in the fragmentation path, and implement the MCTP-specific parts of an ext copy operation.
