Date: Fri, 25 Sep 2020 21:26:41 -0700 From: John Fastabend <john.fastabend@...il.com> To: ast@...nel.org, daniel@...earbox.net Cc: netdev@...r.kernel.org, john.fastabend@...il.com, jakub@...udflare.com, lmb@...udflare.com Subject: [bpf-next PATCH 0/2] Add skb_adjust_room() for SK_SKB This implements the helper skb_adjust_room() for BPF_SKS_BK_STREAM_VERDICT programs so we can push/pop headers from the data on recieve. The obvious use case is to pop TLS headers of kTLS packets. The first patch implements the helper and the second updates test_sockmap to use it removing some case handling we had to do earlier to account for the TLS headers in the kTLS case. I have a couple more series to flush off my stack then I'll work on modernizing the test_sockmap tests themselves. It was created before global data and a few other nice things so its a bit more verbose than necessary.
