Although CONFIG_VSOCKETS_DIAG depends on CONFIG_VSOCKETS,
vsock_init_tables() is not always called, it is called only
if other modules call its caller. Therefore if we only
enable CONFIG_VSOCKETS_DIAG, it would crash kernel on uninitialized
vsock_bind_table.
This patch fixes it by moving vsock_init_tables() to its own
module_init().
Fixes: 413a4317aca7 ("VSOCK: add sock_diag interface")

Make the LAN9303 work when lan9303_probe() is called twice.
For some unknown reason the LAN9303 switch fail to forward data when switch
fabric port 0 TX is disabled during probe. (Write of LAN9303_MAC_TX_CFG_0
in lan9303_disable_processing_port().)
In that situation the switch fabric seem to receive frames, because the ALR
is learning addresses. But no frames are transmitted on any of the ports.
In our system lan9303_probe() is called twice, first time
dsa_register_switch() return -EPROBE_DEFER. As an experiment, modified the
code to skip writing LAN9303_MAC_TX_CFG_0, port 0 during the first probe.
Then the switch works as expected.
Resolve the problem by not calling lan9303_disable_processing_port() on
port 0 during probe. Ports 1 and 2 are still disabled.
Although unsatisfying that the exact failure mechanism is not known,
the patch should not cause any harm.

net: dsa: don't unmask port bitmaps
DSA has several bitmaps to store the type of ports: cpu_port_mask,
dsa_port_mask and enabled_port_mask. But the code is inconsistently
unmasking them.
The legacy code tries to unmask cpu_port_mask and dsa_port_mask but
skips enabled_port_mask.
The new bindings unmasks cpu_port_mask and enabled_port_mask but skips
dsa_port_mask.
In fact there is no need to unmask them because we are in the error
path, and they won't be used after. Instead of fixing the unmasking,
simply remove them.

The unapply functions are called on the error path.
As for dsa_port_mask, enabled_port_mask and cpu_port_mask won't be used
after so there's no need to unmask the corresponding port bit from them.
This makes dsa_cpu_port_unapply() and dsa_dsa_port_unapply() identical,
which can be factorized later.

net: bcmgenet: start/stop sequence refinement
This commit set is the result of an investigation into an issue that
occurred when bringing the interface up and down repeatedly with an
external 100BASE-T PHY. In some cases the MAC would experience mass
receive packet duplication that could in rare cases lead to a stall
from overflow. The fix for this is contained in the third commit.
The first 3 commits represent bug fixes that should be applied to the
net repository and are candidates for backporting to stable releases.
The remaining commits are enhancements which is why the set is being
submitted to net-next but they are implemented on top of the fixes.
The first fix is provided as justification for why the set isn't
split between a net submission and a net-next submission.

Now that the software reset of the PHY has been removed it is no
longer necessary to retain a private pointer to the phydev for
use when the PHY is detached (which isn't generally safe anyway).
The driver now uses the phydev member attached to the net_device.
For ethtool commands that have a PHY component, an explicit check
is made to prevent accessing an invalid phydev pointer when one
is not attached (e.g. interface is down).

Since the NAPI interrupts are basically ignored when NAPI is
disabled we don't need to mask them within the functions
bcmgenet_disable_tx_napi() and bcmgenet_disable_rx_napi().
So wait until all NAPI instances are disabled and mask all of the
bcmgenet driver interrupts together in bcmgenet_netif_stop().
The interrupts can still be enabled in the functions
bcmgenet_enable_tx_napi() and bcmgenet_enable_rx_napi(), but use
the ring context int_enable() method to keep the functionality
consistent and the code cleaner.

It is necessary for the UniMAC to be clocked at least 5 cycles
while the sw_reset is asserted to ensure a clean reset.
It was discovered that this condition was not being met when
connected to an external RGMII PHY that disabled the Rx clock in
the Power Save state.
This commit modifies the reset_umac function to place the (RG)MII
interface into a local loopback mode where the Rx clock comes
from the GENET sourced Tx clk during the sw_reset to ensure the
presence and stability of the clock.
In addition, it turns out that the sw_reset of the UniMAC is not
self clearing, but this was masked by a bug in the timeout code.
The sw_reset is now explicitly cleared by zeroing the UMAC_CMD
register before returning from reset_umac which makes it no
longer necessary to do so in init_umac and makes the clearing of
CMD_TX_EN and CMD_RX_EN by umac_enable_set redundant. The
timeout code (and its associated bug) are removed so reset_umac
no longer needs to return a result, and that means init_umac
that calls reset_umac does not need to as well.

This patch enables multiple bpf attachments for a
kprobe/uprobe/tracepoint single trace event.
Each trace_event keeps a list of attached perf events.
When an event happens, all attached bpf programs will
be executed based on the order of attachment.
A global bpf_event_mutex lock is introduced to protect
prog_array attaching and detaching. An alternative will
be introduce a mutex lock in every trace_event_call
structure, but it takes a lot of extra memory.
So a global bpf_event_mutex lock is a good compromise.
The bpf prog detachment involves allocation of memory.
If the allocation fails, a dummy do-nothing program
will replace to-be-detached program in-place.

Currently, ip6_tnl_xmit_ctl drops tunneled packets if the remote
address (outer v6 destination) is one of host's locally configured
addresses.
Same applies to ip6_tnl_rcv_ctl: it drops packets if the remote address
(outer v6 source) is a local address.
This prevents using ipxip6 (and ip6_gre) tunnels whose local/remote
endpoints are on same host; OTOH v4 tunnels (ipip or gre) allow such
configurations.
An example where this proves useful is a system where entities are
identified by their unique v6 addresses, and use tunnels to encapsulate
traffic between them. The limitation prevents placing several entities
on same host.
Introduce IP6_TNL_F_ALLOW_LOCAL_REMOTE which allows to bypass this
restriction.

Fix various endianness issues in comparisons and assignments. The fix is
entirely cosmetic as all the values fixed are endianness-agnostic.

During the dump the per netlink packet entry counter should be zeroed out
when new packet is created.

Prior to commit b3f55bdda8df, the networking core doesn't wire an in-place
actions list the when the low level driver is called to offload the flow,
but all low level drivers do that (call tcf_exts_to_list()) in their
offloading "add" logic.
Now, the in-place list is set in the core which goes over the list in a loop,
but also by the hw driver when their offloading code is invoked indirectly:
cls_xxx add flow -> tc_setup_cb_call -> tc_exts_setup_cb_egdev_call -> hw driver
which messes up the core list instance upon driver return. Fix that by avoiding
in-place list on the net core code that deals with adding flows.
