net: dsa: rename dsa_is_normal_port helper

This patch renames dsa_is_normal_port to dsa_is_user_port because "user"
is the correct term in the DSA terminology, not "normal".

net: dsa: fix dsa_is_normal_port helper

In order to know if a port is of type user, dsa_is_normal_port checks
that the given port is not of type DSA nor CPU. This is not enough
because a port can be unused.

Without the previous fix, this caused the unused mv88e6xxx ports to be
configured in normal mode.

The ds->enabled_port_mask reports the user ports, so check this instead.

net: dsa: add dsa_is_unused_port helper

As the comment above the chunk states, the b53 driver attempts to
disable the unused ports. But using ds->enabled_port_mask is misleading,
because this mask reports in fact the user ports.

To avoid confusion and fix this, this patch introduces an explicit
dsa_is_unused_port helper which ensures the corresponding bit is not
masked in any of the switch port masks.

Egil Hjelmeland says:

====================
net: dsa: lan9303: Learn addresses on CPU port when bridged

When CPU transmit directly to port using tag, the LAN9303 does not
learn MAC addresses received on the CPU port into the ALR table.
ALR learning is performed only when transmitting using ALR lookup.

Solution:
If the two external ports are bridged and the packet is not STP BPDU,
then use ALR lookup to allow ALR learning on CPU port.
Otherwise transmit directly to port with STP state override.

The first patch moves struct lan9303 to include/linux/dsa/lan9303.h in
order to prepare for the second patch.

Changes v1 -> v2:
 - new file: include/linux/dsa/lan9303.h instead of include/linux/lan9303.h
 - include linux/if_ether.h in include/linux/dsa/lan9303.h
 - renamed lan9303_tx_use_arl to lan9303_xmit_use_arl for consistency.

bpf: remove tail_call and get_stackid helper declarations from bpf.h

commit afdb09c720b6 ("security: bpf: Add LSM hooks for bpf object related
syscall") included linux/bpf.h in linux/security.h. As a result, bpf
programs including bpf_helpers.h and some other header that ends up
pulling in also security.h, such as several examples under samples/bpf,
fail to compile because bpf_tail_call and bpf_get_stackid are now
"redefined as different kind of symbol".

>From bpf.h:

u64 bpf_tail_call(u64 ctx, u64 r2, u64 index, u64 r4, u64 r5);
u64 bpf_get_stackid(u64 r1, u64 r2, u64 r3, u64 r4, u64 r5);

Whereas in bpf_helpers.h they are:

static void (*bpf_tail_call)(void *ctx, void *map, int index);
static int (*bpf_get_stackid)(void *ctx, void *map, int flags);

Fix this by removing the unused declaration of bpf_tail_call and moving
the declaration of bpf_get_stackid in bpf_trace.c, which is the only
place where it's needed.

thunderbolt: Drop sequence number check from tb_xdomain_match()

Commit 9a03c3d398c1 ("thunderbolt: Fix a couple right shifting to zero
bugs") revealed an issue that was previously hidden because we never
actually compared received XDomain message sequence numbers properly.
The idea with these sequence numbers is that the responding host uses
the same sequence number that was in the request packet which we can
then check at the requesting host.

However, testing against macOS it looks like it does not follow this but
instead uses some other logic. Windows driver on the other hand handles
it the same way than Linux.

In order to be able to talk to macOS again, fix this so that we drop the
whole sequence number check. This effectively works exactly the same
than it worked before the aforementioned commit. This also follows the
logic the original P2P networking code used.

net: dsa: lan9303: Do not disable switch fabric port 0 at .probe

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,

net: bcmgenet: enable loopback during UniMAC sw_reset

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.

net: bcmgenet: correct bad merge

As noted in the net-next submission for GENETv5 support [1], there
were merge conflicts with an earlier net submission [2] that had not
yet found its way to the net-next repository.

Unfortunately, when the branches were merged the conflicts were not
correctly resolved.  This commit attempts to correct that.

macvlan: remove unused fields in struct macvlan_dev

commit 635b8c8ecdd2 ("tap: Renaming tap related APIs, data structures,
macros") captured all the tap related fields into a new struct tap_dev.
However, it failed to remove those fields from struct macvlan_dev.
Those fields are currently unused and must be removed. While there
I moved the comment for MAX_TAP_QUEUES to the right place.

tipc: eliminate KASAN warning

The following warning was reported by syzbot on Oct 24. 2017:
KASAN: slab-out-of-bounds Read in tipc_nametbl_lookup_dst_nodes

This is a harmless bug, but we still want to get rid of the warning,
so we swap the two conditions in question.

Merge branch 'net-remove-rtmsg_ifinfo-used-in-bridge-and-bonding'

Xin Long says:

====================
net: remove rtmsg_ifinfo used in bridge and bonding

It's better to send notifications to userspace by the events in
rtnetlink_event, instead of calling rtmsg_ifinfo directly.

This patcheset is to remove rtmsg_ifinfo called in bonding and
bridge, the notifications can be handled by NETDEV_CHANGEUPPER
and NETDEV_CHANGELOWERSTATE events in rtnetlink_event.

It could also fix some redundant notifications from bonding and
bridge.

v1->v2:
  - post to net-next.git instead of net.git, for it's more like an
    improvement for bonding
v2->v3:
  - add patch 1/4 to remove rtmsg_ifinfo called in add_del_if
