Sebastian Andrzej Siewior f053322543 xsk: Add truesize to skb_add_rx_frag(). ... [ Upstream commit 2127c60438 ] xsk_build_skb() allocates a page and adds it to the skb via skb_add_rx_frag() and specifies 0 for truesize. This leads to a warning in skb_add_rx_frag() with CONFIG_DEBUG_NET enabled because size is larger than truesize. Increasing truesize requires to add the same amount to socket's sk_wmem_alloc counter in order not to underflow the counter during release in the destructor (sock_wfree()). Pass the size of the allocated page as truesize to skb_add_rx_frag(). Add this mount to socket's sk_wmem_alloc counter.
