From 210620ae44a83f25220450bbfcc22e6fe986b25f Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 16 May 2023 18:50:37 -0700 Subject: tls: rx: strp: set the skb->len of detached / CoW'ed skbs alloc_skb_with_frags() fills in page frag sizes but does not set skb->len and skb->data_len. Set those correctly otherwise device offload will most likely generate an empty skb and hit the BUG() at the end of __skb_nsg().
