TCP zerocopy takes a uarg reference for every skb, plus one for the
tcp_sendmsg_locked datapath temporarily, to avoid reaching refcnt zero
as it builds, sends and frees skbs inside its inner loop.
UDP and RAW zerocopy do not send inside the inner loop so do not need
the extra sock_zerocopy_get + sock_zerocopy_put pair. Commit
52900d22288ed ("udp: elide zerocopy operation in hot path") introduced
extra_uref to pass the initial reference taken in sock_zerocopy_alloc
to the first generated skb.
But, sock_zerocopy_realloc takes this extra reference at the start of
every call. With MSG_MORE, no new skb may be generated to attach the
extra_uref to, so refcnt is incorrectly 2 with only one skb.

When parsing an ethtool flow spec to build a flow_rule, the code checks
if both the vlan etype and the vlan tci are specified by the user to add
a FLOW_DISSECTOR_KEY_VLAN match.
However, when the user only specified a vlan etype or a vlan tci, this
check silently ignores these parameters.
For example, the following rule :
ethtool -N eth0 flow-type udp4 vlan 0x0010 action -1 loc 0
will result in no error being issued, but the equivalent rule will be
created and passed to the NIC driver :
ethtool -N eth0 flow-type udp4 action -1 loc 0
In the end, neither the NIC driver using the rule nor the end user have
a way to know that these keys were dropped along the way, or that
incorrect parameters were entered.
This kind of check should be left to either the driver, or the ethtool
flow spec layer.
This commit makes so that ethtool parameters are forwarded as-is to the
NIC driver.
Since none of the users of ethtool_rx_flow_rule_create are using the
VLAN dissector, I don't think this qualifies as a regression.

If a network driver provides to napi_gro_frags() an

to gro_pull_from_frag0() will 'consume' the fragment

Fixes for DSA tagging using 802.1Q
During the prototyping for the "Decoupling PHYLINK from struct
net_device" patchset, the CPU port of the sja1105 driver was moved to a
different spot. This uncovered an issue in the tag_8021q DSA code,
which used to work by mistake - the CPU port was the last hardware port
numerically, and this was masking an ordering issue which is very likely
to be seen in other drivers that make use of 802.1Q tags.
A question was also raised whether the VID numbers bear any meaning, and
the conclusion was that they don't, at least not in an absolute sense.
The second patch defines bit fields inside the DSA 802.1Q VID so that
tcpdump can decode it unambiguously (although the meaning is now clear
even by visual inspection).
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Tools like tcpdump need to be able to decode the significance of fake
VLAN headers that DSA uses to separate switch ports.
But currently these have no global significance - they are simply an
ordered list of DSA_MAX_SWITCHES x DSA_MAX_PORTS numbers ending at 4095.
The reason why this is submitted as a fix is that the existing mapping
of VIDs should not enter into a stable kernel, so we can pretend that
only the new format exists. This way tcpdump won't need to try to make
something out of the VLAN tags on 5.2 kernels.

The 802.1Q tagging performs an unbalanced setup in terms of RX VIDs on
the CPU port. For the ingress path of a 802.1Q switch to work, the RX
VID of a port needs to be seen as tagged egress on the CPU port.
While configuring the other front-panel ports to be part of this VID,
for bridge scenarios, the untagged flag is applied even on the CPU port
in dsa_switch_vlan_add. This happens because DSA applies the same flags
on the CPU port as on the (bridge-controlled) slave ports, and the
effect in this case is that the CPU port tagged settings get deleted.
Instead of fixing DSA by introducing a way to control VLAN flags on the
CPU port (and hence stop inheriting from the slave ports) - a hard,
perhaps intractable problem - avoid this situation by moving the setup
part of the RX VID on the CPU port after all the other front-panel ports
have been added to the VID.

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().

Calling sys_ni_syscall through a syscall_fn_t pointer trips indirect
call Control-Flow Integrity checking due to a function type
mismatch. Use SYSCALL_DEFINE0 for __arm64_sys_ni_syscall instead and
remove the now unnecessary casts.

Although a syscall defined using SYSCALL_DEFINE0 doesn't accept
parameters, use the correct function type to avoid indirect call
type mismatches with Control-Flow Integrity checking.

Syscall wrappers in <asm/syscall_wrapper.h> use const struct pt_regs *

Fix this by adding the missing "ULL" suffixes.
Add the same suffix to the last constant, to maintain consistency.
