Jakub Kicinski b026755cc9 tls: rx: strp: don't use GFP_KERNEL in softirq context ... commit 74836ec828 upstream. When receive buffer is small, or the TCP rx queue looks too complicated to bother using it directly - we allocate a new skb and copy data into it. We already use sk->sk_allocation... but nothing actually sets it to GFP_ATOMIC on the ->sk_data_ready() path. Users of HW offload are far more likely to experience problems due to scheduling while atomic. "Copy mode" is very rarely triggered with SW crypto.
