When a device is stacked like (team, bonding, failsafe or netvsc) the
XDP generic program for the parent device was not called.

Move the call to XDP generic inside __netif_receive_skb_core where
it can be done multiple times for stacked case.

Stephen Hemminger 996ed04741 netvsc: unshare skb in VF rx handler
The netvsc VF skb handler should make sure that skb is not
shared. Similar logic already exists in bonding and team device
drivers.

This is not an issue in practice because the VF devicex
does not send up shared skb's. But the netvsc driver
should do the right thing if it did.

Sean Tranchetti f2696099c6 udp: Avoid post-GRO UDP checksum recalculation
Currently, when resegmenting an unexpected UDP GRO packet, the full UDP
checksum will be calculated for every new SKB created by skb_segment()
because the netdev features passed in by udp_rcv_segment() lack any
information about checksum offload capabilities.

Usually, we have no need to perform this calculation again, as
  1) The GRO implementation guarantees that any packets making it to the
     udp_rcv_segment() function had correct checksums, and, more
     importantly,
  2) Upon the successful return of udp_rcv_segment(), we immediately pull
     the UDP header off and either queue the segment to the socket or
     hand it off to a new protocol handler.

Unless userspace has set the IP_CHECKSUM sockopt to indicate that they
want the final checksum values, we can pass the needed netdev feature
flags to __skb_gso_segment() to avoid checksumming each segment in
skb_segment().

Linus Torvalds bec7550cca The Sphinx 2.0 release contained a few incompatible API changes that broke
our extensions and, thus, the documentation build in general.  Who knew
 that those deprecation warnings it was outputting actually meant we should
 change something?  This set of fixes makes the build work again with
 Sphinx 2.0 and eliminates the warnings for 1.8.  As part of that, we also
 need a few fixes to the docs for places where the new Sphinx is more
 strict.
 
 It is a bit late in the cycle for this kind of change, but it does fix
 problems that people are experiencing now.
 
 There has been some talk of raising the minimum version of Sphinx we
 support.  I don't want to do that abruptly, though, so these changes add
 some glue to continue to support versions back to 1.3.  We will be adding
 some infrastructure soon to nudge users of old versions forward, with the
 idea of maybe increasing our minimum version (and removing this glue)
 sometime in the future.

Shuah Khan 3ea3091f1b usbip: usbip_host: fix stub_dev lock context imbalance regression
Fix the following sparse context imbalance regression introduced in

Yoshihiro Shimoda 315ca92dd8 net: sh_eth: fix mdio access in sh_eth_close() for R-Car Gen2 and RZ/A1 SoCs
The sh_eth_close() resets the MAC and then calls phy_stop()
so that mdio read access result is incorrect without any error
according to kernel trace like below:

ifconfig-216   [003] .n..   109.133124: mdio_access: ee700000.ethernet-ffffffff read  phy:0x01 reg:0x00 val:0xffff

According to the hardware manual, the RMII mode should be set to 1
before operation the Ethernet MAC. However, the previous code was not
set to 1 after the driver issued the soft_reset in sh_eth_dev_exit()
so that the mdio read access result seemed incorrect. To fix the issue,
this patch adds a condition and set the RMII mode register in
sh_eth_dev_exit() for R-Car Gen2 and RZ/A1 SoCs.

Note that when I have tried to move the sh_eth_dev_exit() calling
after phy_stop() on sh_eth_close(), but it gets worse (kernel panic
happened and it seems that a register is accessed while the clock is
off).

Eric W. Biederman d76cac67db signal/arm64: Use force_sig not force_sig_fault for SIGKILL
I don't think this is userspace visible but SIGKILL does not have
any si_codes that use the fault member of the siginfo union.  Correct
this the simple way and call force_sig instead of force_sig_fault when
the signal is SIGKILL.

The two know places where synchronous SIGKILL are generated are
do_bad_area and fpsimd_save.  The call paths to force_sig_fault are:
do_bad_area
  arm64_force_sig_fault
    force_sig_fault
force_signal_inject
  arm64_notify_die
    arm64_force_sig_fault
       force_sig_fault

Which means correcting this in arm64_force_sig_fault is enough
to ensure the arm64 code is not misusing the generic code, which
could lead to maintenance problems later.

We met another Acer Aspire laptop which has the problem on the
headset-mic, the Pin 0x19 is not set the corret configuration for a
mic and the pin presence can't be detected too after plugging a
headset. Kailang suggested that we should set the coeff to enable the
mic and apply the ALC269_FIXUP_LIFEBOOK_EXTMIC. After doing that,
both headset-mic presence and headset-mic work well.

The existing ALC255_FIXUP_ACER_MIC_NO_PRESENCE set the headset-mic
jack to be a phantom jack. Now since the jack can support presence
unsol event, let us imporve it to set the jack to be a normal jack.

Saeed Mahameed c0194e2d0e net/mlx5e: Disable rxhash when CQE compress is enabled
When CQE compression is enabled (Multi-host systems), compressed CQEs
might arrive to the driver rx, compressed CQEs don't have a valid hash
offload and the driver already reports a hash value of 0 and invalid hash
type on the skb for compressed CQEs, but this is not good enough.

On a congested PCIe, where CQE compression will kick in aggressively,
gro will deliver lots of out of order packets due to the invalid hash
and this might cause a serious performance drop.

The only valid solution, is to disable rxhash offload at all when CQE
compression is favorable (Multi-host systems).

Stefano Brivio 73f51d151e selftests: pmtu: Fix encapsulating device in pmtu_vti6_link_change_mtu
In the pmtu_vti6_link_change_mtu test, both local and remote addresses
for the vti6 tunnel are assigned to the same address given to the dummy
interface that we use as encapsulating device with a known MTU.

This works as long as the dummy interface is actually selected, via
rt6_lookup(), as encapsulating device. But if the remote address of the
tunnel is a local address too, the loopback interface could also be
selected, and there's nothing wrong with it.

This is what some older -stable kernels do (3.18.z, at least), and
nothing prevents us from subtly changing FIB implementation to revert
back to that behaviour in the future.

Define an IPv6 prefix instead, and use two separate addresses as local
and remote for vti6, so that the encapsulating device can't be a
loopback interface.

Tomas Bortoli dfb4a6f219 tracing: Avoid memory leak in predicate_parse()
In case of errors, predicate_parse() goes to the out_free label
to free memory and to return an error code.

However, predicate_parse() does not free the predicates of the
temporary prog_stack array, thence leaking them.

Madalin Bucur 7aae703f80 dpaa_eth: use only online CPU portals
Make sure only the portals for the online CPUs are used.
Without this change, there are issues when someone boots with
maxcpus=n, with n < actual number of cores available as frames
either received or corresponding to the transmit confirmation
path would be offered for dequeue to the offline CPU portals,
getting lost.
