Traceroute executed in a vrf succeeds if no device is given or if the
vrf is given as the device, but fails if the interface is given as the
device. This is for default UDP probes, it succeeds for TCP SYN or ICMP
ECHO probes. As the skb bound dev is the interface and the sk dev is
the vrf, sk lookup fails for ICMP_DEST_UNREACH and ICMP_TIME_EXCEEDED
messages. The solution is for the secondary dev to be passed so that
the interface is available for the device match to succeed, in the same
way as is already done for non-error cases.

Based on RFC 4541, 2.1.1. IGMP Forwarding Rules
The switch supporting IGMP snooping must maintain a list of
multicast routers and the ports on which they are attached. This
list can be constructed in any combination of the following ways:
a) This list should be built by the snooping switch sending
Multicast Router Solicitation messages as described in IGMP
Multicast Router Discovery [MRDISC]. It may also snoop
Multicast Router Advertisement messages sent by and to other
nodes.
b) The arrival port for IGMP Queries (sent by multicast routers)
where the source address is not 0.0.0.0.
We should not add the port to router list when receives query with source
0.0.0.0.

Commit a61bbcf28a8c ("[NET]: Store skb->timestamp as offset to a base
timestamp") introduces a neighbour control buffer and zeroes it out in
ndisc_rcv(), as ndisc_recv_ns() uses it.
Commit f2776ff04722 ("[IPV6]: Fix address/interface handling in UDP and
DCCP, according to the scoping architecture.") introduces the usage of the
IPv6 control buffer in protocol error handlers (e.g. inet6_iif() in
present-day __udp6_lib_err()).
Now, with commit b94f1c0904da ("ipv6: Use icmpv6_notify() to propagate
redirect, instead of rt6_redirect()."), we call protocol error handlers
from ndisc_redirect_rcv(), after the control buffer is already stolen and
some parts are already zeroed out. This implies that inet6_iif() on this
path will always return zero.
This gives unexpected results on UDP socket lookup in __udp6_lib_err(), as
we might actually need to match sockets for a given interface.
Instead of always claiming the control buffer in ndisc_rcv(), do that only
when needed.

It was reported that WoL from S5 is broken (WoL from S3 works) and the
analysis showed that during system shutdown the network interface was
brought down already when the actual kernel shutdown started.
Therefore netif_running() returned false and as a consequence the PHY
was suspended. Obviously WoL wasn't working then.
To fix this the original patch needs to be effectively reverted.
A side effect is that when normally bringing down the interface and
WoL is enabled the PHY will remain powered on (like it was before the
original patch).

The intent of ip6_route_check_nh_onlink is to make sure the gateway
given for an onlink route is not actually on a connected route for
a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then
an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway
lookup hits the default route then it most likely will be a different
interface than the onlink route which is ok.
Update ip6_route_check_nh_onlink to disregard the device mismatch
if the gateway lookup hits the default route. Turns out the existing
onlink tests are passing because there is no default route or it is
an unreachable default, so update the onlink tests to have a default
route other than unreachable.

When the physical link goes up or down, the driver is supposed to
receive a link status event (LSE). The driver currently has the code
to handle LSEs but there is no firmware support for this feature yet.
So this patch adds the ability for the driver to poll for link status
changes. The polling itself is done in ice_watchdog_subtask.
For namespace cleanliness, this patch also removes code that handles
LSE. This code will be reintroduced once the feature is officially
supported.

Current handling of CHECKSUM_COMPLETE packets by the UDP stack is
incorrect for any packet that has an incorrect checksum value.
udp4/6_csum_init() will both make a call to
__skb_checksum_validate_complete() to initialize/validate the csum
field when receiving a CHECKSUM_COMPLETE packet. When this packet
fails validation, skb->csum will be overwritten with the pseudoheader
checksum so the packet can be fully validated by software, but the
skb->ip_summed value will be left as CHECKSUM_COMPLETE so that way
the stack can later warn the user about their hardware spewing bad
checksums. Unfortunately, leaving the SKB in this state can cause
problems later on in the checksum calculation.
Since the the packet is still marked as CHECKSUM_COMPLETE,
udp_csum_pull_header() will SUBTRACT the checksum of the UDP header
from skb->csum instead of adding it, leaving us with a garbage value
in that field. Once we try to copy the packet to userspace in the
udp4/6_recvmsg(), we'll make a call to skb_copy_and_csum_datagram_msg()
to checksum the packet data and add it in the garbage skb->csum value
to perform our final validation check.
Since the value we're validating is not the proper checksum, it's possible
that the folded value could come out to 0, causing us not to drop the
packet. Instead, we believe that the packet was checksummed incorrectly
by hardware since skb->ip_summed is still CHECKSUM_COMPLETE, and we attempt
to warn the user with netdev_rx_csum_fault(skb->dev);
Unfortunately, since this is the UDP path, skb->dev has been overwritten
by skb->dev_scratch and is no longer a valid pointer, so we end up
reading invalid memory.
This patch addresses this problem in two ways:
1) Do not use the dev pointer when calling netdev_rx_csum_fault()
from skb_copy_and_csum_datagram_msg(). Since this gets called
from the UDP path where skb->dev has been overwritten, we have
no way of knowing if the pointer is still valid. Also for the
sake of consistency with the other uses of
netdev_rx_csum_fault(), don't attempt to call it if the
packet was checksummed by software.
2) Add better CHECKSUM_COMPLETE handling to udp4/6_csum_init().
If we receive a packet that's CHECKSUM_COMPLETE that fails
verification (i.e. skb->csum_valid == 0), check who performed
the calculation. It's possible that the checksum was done in
software by the network stack earlier (such as Netfilter's
CONNTRACK module), and if that says the checksum is bad,
we can drop the packet immediately instead of waiting until
we try and copy it to userspace. Otherwise, we need to
mark the SKB as CHECKSUM_NONE, since the skb->csum field
no longer contains the full packet checksum after the
call to __skb_checksum_validate_complete().

But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on

the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

With EDT model, SRTT no longer is inflated by pacing delays.
This means that RTO and some other xmit timers might be setup
incorrectly. This is particularly visible with either :
- Very small enforced pacing rates (SO_MAX_PACING_RATE)
- Reduced rto (from the default 200 ms)
This can lead to TCP flows aborts in the worst case,
or spurious retransmits in other cases.
For example, this session gets far more throughput
than the requested 80kbit :
$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET

Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
540000 262144 262144 104.00 2.66
With the fix :
$ netperf -H 127.0.0.2 -l 100 -- -q 10000
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET

EDT allows for better control of rtx timers, since TCP has
a better idea of the earliest departure time of each skb
in the rtx queue. We only have to eventually add to the
timer the difference of the EDT time with current time.

This reverts commit dd979b4df817e9976f18fb6f9d134d6bc4a3c317.
This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an
internal TCP socket for the initial handshake with the remote peer.
Whenever the SMC connection can not be established this TCP socket is
used as a fallback. All socket operations on the SMC socket are then
forwarded to the TCP socket. In case of poll, the file->private_data
pointer references the SMC socket because the TCP socket has no file
assigned. This causes tcp_poll to wait on the wrong socket.

There is a compatibility issue between RTL8211E implemented
in Developerbox and netsec ethernet controller IP.
Our MDIO controller stops MDC clock right after the write
access, but RTL8211E expects MDC clock must be kept toggling
for several clock cycle with MDIO high before entering
the IDLE state. Without keeping clock after write access,
write access is not correctly handled and register is not
updated.
To meet this requirement, netsec driver needs to issue dummy
read(e.g. read PHYID1(offset 0x2) register) right after write
access, to keep MDC clock.
We think this compatibility issue is a problem specific to
our MDIO controller and RTL8211E.

In ndo_stop, driver resets the netsec ethernet controller IP.
When the netsec IP is reset, HW running mode turns to NRM mode
and driver has to wait until this mode transition completes.
But mode transition to NRM will not complete if the PHY is
in normal operation state. Netsec IP requires PHY is in
power down state when it is reset.
This modification stops the PHY before resetting netsec.
Together with this modification, phy_addr is stored in netsec_priv
structure because ndev->phydev is not yet ready in ndo_init.

After flushing all mcast entries from the table, the ones contained in
mc list of ndev are not restored when promisc mode is toggled off,
because they are considered as synched with ALE, thus, in order to
restore them after promisc mode - reset syncing info. This fix
touches only switch mode devices, including single port boards
like Beagle Bone.

By default NIXLF is set in UCAST mode. This patch adds a new
mailbox message which when sent by a RVU PF changes this default
mode. When promiscuous mode is needed, the reserved promisc entry
for each of RVU PF is setup to match against ingress channel number
only, so that all pkts on that channel are accepted and forwarded
to the mode change requesting PF_FUNC's NIXLF.
PROMISC and ALLMULTI modes are supported only for PFs, for VFs only
UCAST mode is supported.

This patch adds support for a RVU PF/VF to change
NIX Rx flowkey algorithm index in NPC RX RSS_ACTION.
eg: a ethtool command changing RSS algorithm for a netdev
interface would trigger this change in NPC.
If PF/VF doesn't specify any MCAM entry index then default
UCAST entry of the NIXLF attached to PF/VF will be updated
with RSS_ACTION and flowkey index.

Configure NIX RX flowkey algorithm configuration to support
RSS (receive side scaling). Currently support for only L3/L4
2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added.
HW supports upto 32 different flowkey algorithms which SW
can define, this patch defines 9. NPC RX ACTION has to point
to one of these flowkey indices for RSS to work.
The configuration is dependent on NPC parse result's layer
info. So if NPC KPU profile changes suchthat LID/LTYPE values
of above said protocols change then this configuration will
most likely be effected.

Upon NIXLF_ALLOC install a unicast forwarding rule in NPC MCAM
like below
- Match pkt DMAC with NIXLF attached PF/VF's MAC address.
- Ingress channel
- Action is UCAST
- Forward to PF_FUNC of this NIXLF
And broadcast pkt forwarding rule as
- Match L2B bit in MCAM search key
- Ingress channel
- Action is UCAST, for now, later it will be changed to MCAST.
Only PFs can install this rule
Upon NIXLF_FREE disable all MCAM entries in use by that NIXLF.

This patch adds some minimal configuration for NPC MCAM and
LDATA extraction which is sufficient enough to install
ucast/bcast/promiscuous forwarding rules. Below is the
config done
- LDATA extraction config to extract DMAC from pkt
to offset 64bit in MCAM search key.
- Set MCAM lookup keysize to 224bits
- Set MCAM TX miss action to UCAST_DEFAULT
- Set MCAM RX miss action to DROP
Also inorder to have guaranteed space in MCAM to install
ucast forwarding rule for each of RVU PF/VF, reserved
one MCAM entry for each of NIXLF for ucast rule. And two
entries for each of RVU PF. One for bcast pkt replication
and other for promiscuous mode which allows all pkts
received on a HW CGX/LBK channel.

Config NPC layer info from KPU profile into protocol
checker to identify outer L2/IPv4/TCP/UDP headers in a
packet. And enable IPv4 checksum validation.
L3/L4 and L4 CSUM validation will be enabled by PF/VF
drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox
i.e 'nix_lf_alloc_req->rx_cfg'
Also enable setting of NPC_RESULT_S[L2B] when an outer
L2 broadcast address is detected. This will help in
installing NPC MCAM rules for broadcast packets.

Allocate memory for mcast/bcast/mirror replication entry
contexts, replication buffers (used by HW) and config HW
with corresponding memory bases. Added support for installing
MCEs via NIX AQ mbox.
For now support is restricted to broadcast pkt replication,
hence MCE table size and number of replication buffers
allocated are less. Each CGX LMAC mapped RVU PF is assigned
a MCE table of size 'num VFs of that PF + PF'.
