xsk: Add truesize to skb_add_rx_frag().

[ Upstream commit 2127c604383666675789fd4a5fc2aead46c73aad ]

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.

xsk: add multi-buffer support for sockets sharing umem

[ Upstream commit d609f3d228a8efe991f44f11f24146e2a5209755 ]

Userspace applications indicate their multi-buffer capability to xsk
using XSK_USE_SG socket bind flag. For sockets using shared umem the
bind flag may contain XSK_USE_SG only for the first socket. For any
subsequent socket the only option supported is XDP_SHARED_UMEM.

Add option XDP_UMEM_SG_FLAG in umem config flags to store the
multi-buffer handling capability when indicated by XSK_USE_SG option in
bing flag by the first socket. Use this to derive multi-buffer capability
for subsequent sockets in xsk core.

xsk: Skip polling event check for unbound socket

[ Upstream commit e4d008d49a7135214e0ee70537405b6a069e3a3f ]

In xsk_poll(), checking available events and setting mask bits should
be executed only when a socket has been bound. Setting mask bits for
unbound socket is meaningless.

Currently, it checks events even when xsk_check_common() failed.
To prevent this, we move goto location (skip_tx) after that checking.

xsk: Fix xsk_build_skb() error: 'skb' dereferencing possible ERR_PTR()

Currently, xsk_build_skb() is a function that builds skb in two possible
ways and then is ended with common error handling.

We can distinguish four possible error paths and handling in xsk_build_skb():

1. sock_alloc_send_skb fails: Retry (skb is NULL).
2. skb_store_bits fails : Free skb and retry.
3. MAX_SKB_FRAGS exceeded: Free skb, cleanup and drop packet.
4. alloc_page fails for frag: Retry page allocation w/o freeing skb

1] and 3] can happen in xsk_build_skb_zerocopy(), which is one of the
two code paths responsible for building skb. Common error path in
xsk_build_skb() assumes that in case errno != -EAGAIN, skb is a valid
pointer, which is wrong as kernel test robot reports that in
xsk_build_skb_zerocopy() other errno values are returned for skb being
NULL.

To fix this, set -EOVERFLOW as error when MAX_SKB_FRAGS are exceeded
and packet needs to be dropped in both xsk_build_skb() and
xsk_build_skb_zerocopy() and use this to distinguish against all other
error cases. Also, add explicit kfree_skb() for 3] so that handling
of 1], 2], and 3] becomes identical where allocation needs to be retried.
