David Ahern 9ae2872748 net: add extack arg to lwtunnel build state
Pass extack arg down to lwtunnel_build_state and the build_state callbacks.
Add messages for failures in lwtunnel_build_state, and add the extarg to
nla_parse where possible in the build_state callbacks.

Florian Fainelli a399546049 net: phy: Relax error checking on sysfs_create_link()
Some Ethernet drivers will attach/connect to a PHY device before calling
register_netdevice() which is responsible for calling netdev_register_kobject()
which would do the network device's kobject initialization. In such a case,
sysfs_create_link() would return -ENOENT because the network device's kobject
is not ready yet, and we would fail to connect to the PHY device.

In order to keep things simple and symetrical, we just take the success path as
indicative of the ability to access the network device's kobject, and create
the second link if that's the case.

Vlad Yasevich 3d3ea5af5c rtnl: Add support for netdev event to link messages
When netdev events happen, a rtnetlink_event() handler will send
messages for every event in it's white list.  These messages contain
current information about a particular device, but they do not include
the iformation about which event just happened.  So, it is impossible
to tell what just happend for these events.

This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT
that would have an encoding of event that triggered this
message.  This would allow the the message consumer to easily determine
if it needs to perform certain actions.

Ido Schimmel 9341b988e6 bridge: Export multicast enabled state
During enslavement to a bridge, after the CHANGEUPPER is sent, the
multicast enabled state of the bridge isn't propagated down to the
offloading driver unless it's changed.

This patch allows such drivers to query the multicast enabled state from
the bridge, so that they'll be able to correctly configure their flood
tables during port enslavement.

In case multicast is disabled, unregistered multicast packets can be
treated as broadcast and be flooded through all the bridge ports.

Ido Schimmel 1f51445af3 bridge: Export VLAN filtering state
It's useful for drivers supporting bridge offload to be able to query
the bridge's VLAN filtering state.

Currently, upon enslavement to a bridge master, the offloading driver
will only learn about the bridge's VLAN filtering state after the bridge
device was already linked with its slave.

Being able to query the bridge's VLAN filtering state allows such
drivers to forbid enslavement in case resource couldn't be allocated for
a VLAN-aware bridge and also choose the correct initialization routine
for the enslaved port, which is dependent on the bridge type.

Vlad Yasevich 35d2f80b07 vlan: Fix tcp checksum offloads in Q-in-Q vlans
It appears that TCP checksum offloading has been broken for
Q-in-Q vlans.  The behavior was execerbated by the
series
    commit afb0bc972b ("Merge branch 'stacked_vlan_tso'")
that that enabled accleleration features on stacked vlans.

However, event without that series, it is possible to trigger
this issue.  It just requires a lot more specialized configuration.

The root cause is the interaction between how
netdev_intersect_features() works, the features actually set on
the vlan devices and HW having the ability to run checksum with
longer headers.

The issue starts when netdev_interesect_features() replaces
NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM,
if the HW advertises IP|IPV6 specific checksums.  This happens
for tagged and multi-tagged packets.   However, HW that enables
IP|IPV6 checksum offloading doesn't gurantee that packets with
arbitrarily long headers can be checksummed.

This patch disables IP|IPV6 checksums on the packet for multi-tagged
packets.

Mohamad Haj Yahia 73dd3a4839 net/mlx5: Avoid using pending command interface slots
Currently when firmware command gets stuck or it takes long time to
complete, the driver command will get timeout and the command slot is
freed and can be used for new commands, and if the firmware receive new
command on the old busy slot its behavior is unexpected and this could
be harmful.
To fix this when the driver command gets timeout we return failure,
but we don't free the command slot and we wait for the firmware to
explicitly respond to that command.
Once all the entries are busy we will stop processing new firmware
commands.

Eric W. Biederman c70d9d809f ptrace: Properly initialize ptracer_cred on fork
When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default.  This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.

Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.

Fix this by properly initializing ptracer_cred in ptrace_init_task

This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork.  Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

Add messages for non-obvious errors (e.g, no need to add text for malloc
failures or ENODEV failures). This mostly covers the annoying EINVAL errors
Some message strings violate the 80-columns but searchable strings need to
trump that rule.

Jan Glauber c2372c2042 of/platform: Make of_platform_device_destroy globally visible
of_platform_device_destroy is the counterpart to
of_platform_device_create which is a non-static function.

After creating a platform device it might be neccessary
to destroy it to deal with -EPROBE_DEFER where a
repeated of_platform_device_create call would fail otherwise.

Therefore also make of_platform_device_destroy globally visible.

Miroslav Lichvar b50a5c70ff net: allow simultaneous SW and HW transmit timestamping
Add SOF_TIMESTAMPING_OPT_TX_SWHW option to allow an outgoing packet to
be looped to the socket's error queue with a software timestamp even
when a hardware transmit timestamp is expected to be provided by the
driver.

Applications using this option will receive two separate messages from
the error queue, one with a software timestamp and the other with a
hardware timestamp. As the hardware timestamp is saved to the shared skb
info, which may happen before the first message with software timestamp
is received by the application, the hardware timestamp is copied to the
SCM_TIMESTAMPING control message only when the skb has no software
timestamp or it is an incoming packet.

While changing sw_tx_timestamp(), inline it in skb_tx_timestamp() as
there are no other users.

Miroslav Lichvar 90b602f803 net: add function to retrieve original skb device using NAPI ID
Since commit b68581778c ("net: Make skb->skb_iif always track
skb->dev") skbs don't have the original index of the interface which
received the packet. This information is now needed for a new control
message related to hardware timestamping.

Instead of adding a new field to skb, we can find the device by the NAPI
ID if it is available, i.e. CONFIG_NET_RX_BUSY_POLL is enabled and the
driver is using NAPI. Add dev_get_by_napi_id() and also skb_napi_id() to
hide the CONFIG_NET_RX_BUSY_POLL ifdef.

Pablo Neira Ayuso says:

====================
Netfilter/IPVS fixes for net

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

1) When using IPVS in direct-routing mode, normal traffic from the LVS
   host to a back-end server is sometimes incorrectly NATed on the way
   back into the LVS host. Patch to fix this from Julian Anastasov.

2) Calm down clang compilation warning in ctnetlink due to type
   mismatch, from Matthias Kaehlcke.

3) Do not re-setup NAT for conntracks that are already confirmed, this
   is fixing a problem that was introduced in the previous nf-next batch.
   Patch from Liping Zhang.

4) Do not allow conntrack helper removal from userspace cthelper
   infrastructure if already in used. This comes with an initial patch
   to introduce nf_conntrack_helper_put() that is required by this fix.
   From Liping Zhang.

5) Zero the pad when copying data to userspace, otherwise iptables fails
   to remove rules. This is a follow up on the patchset that sorts out
   the internal match/target structure pointer leak to userspace. Patch
   from the same author, Willem de Bruijn. This also comes with a build
   failure when CONFIG_COMPAT is not on, coming in the last patch of
   this series.

6) SYNPROXY crashes with conntrack entries that are created via
   ctnetlink, more specifically via conntrackd state sync. Patch from
   Eric Leblond.

7) RCU safe iteration on set element dumping in nf_tables, from
   Liping Zhang.

8) Missing sanitization of immediate date for the bitwise and cmp
   expressions in nf_tables.

9) Refcounting logic for chain and objects from set elements does not
   integrate into the nf_tables 2-phase commit protocol.

10) Missing sanitization of target verdict in ebtables arpreply target,
    from Gao Feng.

Davide Caratti 43c26a1a45 net: more accurate checksumming in validate_xmit_skb()
skb_csum_hwoffload_help() uses netdev features and skb->csum_not_inet to
determine if skb needs software computation of Internet Checksum or crc32c
(or nothing, if this computation can be done by the hardware). Use it in
place of skb_checksum_help() in validate_xmit_skb() to avoid corruption
of non-GSO SCTP packets having skb->ip_summed equal to CHECKSUM_PARTIAL.

While at it, remove references to skb_csum_off_chk* functions, since they
are not present anymore in Linux  _ see commit cf53b1da73 ("Revert
 "net: Add driver helper functions to determine checksum offloadability"").

Pull ARM SoC fixes from Olof Johansson:
 "We had a small batch of fixes before -rc1, but here is a larger one.
  It contains a backmerge of 4.12-rc1 since some of the downstream
  branches we merge had that as base; at the same time we already had
  merged contents before -rc1 and rebase wasn't the right solution.

  A mix of random smaller fixes and a few things worth pointing out:

   - We've started telling people to avoid cross-tree shared branches if
     all they're doing is picking up one or two DT-used constants from a
     shared include file, and instead to use the numeric values on first
     submission. Follow-up moving over to symbolic names are sent in
     right after -rc1, i.e. here. It's only a few minor patches of this
     type.

   - Linus Walleij and others are resurrecting the 'Gemini' platform,
     and wanted a cut-down platform-specific defconfig for it. So I
     picked that up for them.

   - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
     helps people to prepare patches since it's a pain when defconfig
     and current savedefconfig contents differs too much.

   - Devicetree additions for some pinctrl drivers for Armada that were
     merged this window. I'd have preferred to see those earlier but
     it's not a huge deail.

  The biggest change worth pointing out though since it's touching other
  parts of the tree: We added prefixes to be used when cross-including
  DT contents between arm64 and arm, allowing someone to #include
  <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
  arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
  resulted in a recursive symlink.

  Instead, I've now moved it out of arch/*/boot/dts/include, into a
  shared location under scripts/dtc. While I was at it, I consolidated
  so all architectures now behave the same way in this manner.

  Rob Herring (DT maintainer) has acked it. I cc:d most other arch
  maintainers but nobody seems to care much; it doesn't really affect
  them since functionality is unchanged for them by default"
