      netfilter: nf_tables: always initialize flowtable hook list in transaction · 2c9e4559
      Pablo Neira Ayuso authored 
      The hook list is used if nft_trans_flowtable_update(trans) == true. However,
initialize this list for other cases for safety reasons.

      module: Fix prefix for module.sig_enforce module param · 73503963
      Saravana Kannan authored 
      Commit cfc1d277 ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files.  A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.

This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.

So, set the prefix back to "module.".

Fixes: cfc1d277 ("module: Move all into module/")

      Eric Dumazet says:

====================
net: af_packet: be careful when expanding mac header size

A recent regression in af_packet needed a preliminary debug patch,
which will presumably be useful for next bugs hunting.

The af_packet fix is to make sure MAC headers are contained in
skb linear part, as GSO stack requests.

v2: CONFIG_DEBUG_NET depends on CONFIG_NET to avoid compile
   errors found by kernel bots.

      net/af_packet: make sure to pull mac header · e9d3f809
      Eric Dumazet authored 
      GSO assumes skb->head contains link layer headers.

tun device in some case can provide base 14 bytes,
regardless of VLAN being used or not.

After blamed commit, we can end up setting a network
header offset of 18+, we better pull the missing
bytes to avoid a posible crash in GSO.

      net: add debug info to __skb_pull() · 22296a5c
      Eric Dumazet authored 
      While analyzing yet another syzbot report, I found the following
patch very useful. It allows to better understand what went wrong.

This debug info is only enabled if CONFIG_DEBUG_NET=y,
which is the case for syzbot builds.

      net: stmmac: use dev_err_probe() for reporting mdio bus registration failure · 839612d2
      Rasmus Villemoes authored 
      I have a board where these two lines are always printed during boot:

   imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
   imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed

It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.

Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.

While here, add the missing \n to one of the format strings.
