      Possible problem with e6afc8ac ("udp: remove headers from UDP packets before queueing") · ce25d66a
      Eric Dumazet authored 
      Paul Moore tracked a regression caused by a recent commit, which
mistakenly assumed that sk_filter() could be avoided if socket
had no current BPF filter.

The intent was to avoid udp_lib_checksum_complete() overhead.

But sk_filter() also checks skb_pfmemalloc() and
security_sock_rcv_skb(), so better call it.

      stmmac: do not sleep in atomic context for mdio_reset · f55d84b0
      Vincent Palatin authored 
      stmmac_mdio_reset() has been updated to use msleep rather udelay
(as some PHY requires a one second delay there).
It called from stmmac_resume() within the spin_lock_irqsave block
atomic context triggering 'scheduling while atomic'.

The stmmac_priv lock usage is not fully documented, but it seems
to protect the access to the MAC registers / DMA structures rather
than the MDIO bus or the PHY (which have separate locking),
so we can push the spin_lock after the stmmac_mdio_reset call.

      qed: fix qed_fill_link() error handling · 14b84e86
      Arnd Bergmann authored 
      gcc warns about qed_fill_link possibly accessing uninitialized data:

drivers/net/ethernet/qlogic/qed/qed_main.c: In function 'qed_fill_link':
drivers/net/ethernet/qlogic/qed/qed_main.c:1170:35: error: 'link_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized]

While this warning is only about the specific case of CONFIG_QED_SRIOV
being disabled but the function getting called for a VF (which should
never happen), another possibility is that qed_mcp_get_*() fails without
returning data.

This rearranges the code so we bail out in either of the two cases
and print a warning instead of accessing the uninitialized data.

The qed_link_output structure remains untouched in this case, but
all callers first call memset() on it, so at least we are not leaking
stack data then.

As discussed, we also use a compile-time check to ensure we never
use any of the VF code if CONFIG_QED_SRIOV is disabled, and the
PCI device table is updated to no longer bind to virtual functions
in that configuration.

      net/ethoc: fix null dereference on error exit path · bfa49cfc
      Colin Ian King authored 
      priv is assigned to NULL however some of the early error exit paths to
label 'free' dereference priv, causing a null pointer dereference.

Move the label 'free' to just the free_netdev statement, and add a new
exit path 'free2' for the error cases were clk_disable_unprepare needs
calling before the final free.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Fix incorrect timestamp in nfnetlink_queue introduced when addressing
   y2038 safe timestamp, from Florian Westphal.

2) Get rid of leftover conntrack definition from the previous merge
   window, oneliner from Florian.

3) Make nf_queue handler pernet to resolve race on dereferencing the
   hook state structure with netns removal, from Eric Biederman.

4) Ensure clean exit on unregistered helper ports, from Taehee Yoo.

5) Restore FLOWI_FLAG_KNOWN_NH in nf_dup_ipv6. This got lost while
   generalizing xt_TEE to add packet duplication support in nf_tables,
   from Paolo Abeni.

6) Insufficient netlink NFTA_SET_TABLE attribute check in
   nf_tables_getset(), from Phil Turnbull.

7) Reject helper registration on duplicated ports via modparams.
