net: ipa: last things before PM conversion
This series contains a few remaining changes needed before fully
switching over to using runtime power management rather than the
previous "IPA clock" mechanism.
The first patch moves the calls to enable and disable the IPA
interrupt as a system wakeup interrupt into "ipa_clock.c" with the
rest of the power-related code.
The second adds a flag to make it possible to distinguish runtime
suspend from system suspend.
The third and fourth patches arrange for the ->start_xmit path to
resume hardware if necessary, to ensure it is powered. If power is
not active, the TX queue is stopped, and arrangements are made for
the queue to be restarted once hardware power is active again.
The fifth patch keeps the TX queue active during suspend. This
isn't necessary for system suspend but it's important for runtime
suspend.
And the last patch makes it so we don't hold the hardware active
while the modem network device is open.
====================

Currently a clock reference is taken whenever the ->ndo_open
callback for the modem netdev is called. That reference is dropped
when the device is closed, in ipa_stop().
We no longer need this, because ipa_start_xmit() now handles the
situation where the hardware power state is not active.
Drop the clock reference in ipa_open() when we're done, and take a
new reference in ipa_stop() before we begin closing the interface.
Finally (and unrelated, but trivial), change the return type of
ipa_start_xmit() to be netdev_tx_t instead of int.

Currently we stop the modem netdev transmit queue when suspending
the hardware. For system suspend this ensured we'd never attempt
to transmit while attempting to suspend the modem endpoints.
For runtime suspend, the IPA hardware might get suspended while the
system is operating. In that case we want an attempt to transmit a
packet to cause the hardware to resume if necessary. But if we
disable the queue this cannot happen.
So stop disabling the queue on suspend. In case we end up disabling
it in ipa_start_xmit() (see the previous commit), we still arrange
to start the TX queue on resume.

We need to ensure the hardware is powered when we transmit a packet.
But if it's not, we can't block to wait for it. So asynchronously
request power in ipa_start_xmit(), and only proceed if the return
value indicates the power state is active.
If the hardware is not active, a runtime resume request will have
been initiated. In that case, stop the network stack from further
transmit attempts until the resume completes. Return NETDEV_TX_BUSY,
to retry sending the packet once the queue is restarted.
If the power request returns an error (other than -EINPROGRESS,
which just means a resume requested elsewhere isn't complete), just
drop the packet.

Create a new work structure in the modem private data, and use it to
re-enable the modem network device transmit queue when resuming.
This is needed by the next patch, which stops the TX queue if IPA
power isn't active when a transmit request arrives. Packets will
start arriving the instant the TX queue is enabled, but resuming
isn't complete until ipa_modem_resume() returns. This way we're
sure to be resumed before transmits are allowed again.
Cancel it before calling ipa_stop() in ipa_modem_stop() to ensure
the transmit queue restart completes before it gets stopped there.

net: bridge: mcast: dump querier state
This set adds the ability to dump the current multicast querier state.
This is extremely useful when debugging multicast issues, we've had
many cases of unexpected queriers causing strange behaviour and mcast
test failures. The first patch changes the querier struct to record
a port device's ifindex instead of a pointer to the port itself so we
can later retrieve it, I chose this way because it's much simpler
and doesn't require us to do querier port ref counting, it is best
effort anyway. Then patch 02 makes the querier address/port updates
consistent via a combination of multicast_lock and seqcount, so readers
can only use seqcount to get a consistent snapshot of address and port.
Patch 03 is a minor cleanup in preparation for the dump support, it
consolidates IPv4 and IPv6 querier selection paths as they share most of
the logic (except address comparisons of course). Finally the last three
patches add the new querier state dumping support, for the bridge's
global multicast context we embed the BRIDGE_QUERIER_xxx attributes
into IFLA_BR_MCAST_QUERIER_STATE and for the per-vlan global mcast
contexts we embed them into BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE.
The structure is:
[IFLA_BR_MCAST_QUERIER_STATE / BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE]
`[BRIDGE_QUERIER_IP_ADDRESS] - ip address of the querier
`[BRIDGE_QUERIER_IP_PORT] - bridge port ifindex where the querier was
seen (set only if external querier)
`[BRIDGE_QUERIER_IP_OTHER_TIMER] - other querier timeout
`[BRIDGE_QUERIER_IPV6_ADDRESS] - ip address of the querier
`[BRIDGE_QUERIER_IPV6_PORT] - bridge port ifindex where the querier
was seen (set only if external querier)
`[BRIDGE_QUERIER_IPV6_OTHER_TIMER] - other querier timeout
Later we can also add IGMP version of seen queriers and last seen values
from the queries.

Currently when a querier port is detected its net_bridge_port pointer is
recorded, but it's used only for comparisons so it's fine to have stale
pointer, in order to dereference and use the port pointer a proper
accounting of its usage must be implemented adding unnecessary
complexity. To solve the problem we can just store the netdevice ifindex
instead of the port pointer and retrieve the bridge port. It is a best
effort and the device needs to be validated that is still part of that
bridge before use, but that is small price to pay for avoiding querier
reference counting for each port/vlan.

mptcp: Improve use of backup subflows
Multipath TCP combines multiple TCP subflows in to one stream, and the
MPTCP-level socket must decide which subflow to use when sending (or
resending) chunks of data. The choice of the "best" subflow to transmit
on can vary depending on the priority (normal or backup) for each
subflow and how well the subflow is performing.
In order to improve MPTCP performance when some subflows are failing,
this patch set changes how backup subflows are utilized and introduces
tracking of "stale" subflows that are still connected but not making
progress.
Patch 1 adjusts MPTCP-level retransmit timeouts to use data from all
subflows.
Patch 2 makes MPTCP-level retransmissions less aggressive to avoid
resending data that's still queued at the TCP level.
Patch 3 changes the way pending data is handled when subflows are
closed. Unacked MPTCP-level data still in the subflow tx queue is
immediately moved to another subflow for transmission instead of waiting
for MPTCP-level timeouts to trigger retransmission.
Patch 4 has some sysctl code cleanup.
Patches 5 and 6 add tracking of "stale" subflows, so only underlying TCP
subflow connections that appear to be making progress are considered
when selecting a subflow to (re)transmit data. How fast a subflow goes
stale is configurable with a per-namespace sysctl. Related MIBS are
added too.
Patch 7 makes sure the backup flag is always correctly recorded when the
MP_JOIN SYN/ACK is received for an added subflow.
Patch 8 adds more test cases for backup subflows and stale subflows.

The msk can use backup subflows to transmit in-sequence data
only if there are no other active subflow. On active backup
scenario, the MPTCP connection can do forward progress only
due to MPTCP retransmissions - rtx can pick backup subflows.
This patch introduces a new flag flow MPTCP subflows: if the
underlying TCP connection made no progresses for long time,
and there are other less problematic subflows available, the
given subflow become stale.
Stale subflows are not considered active: if all non backup
subflows become stale, the MPTCP scheduler can pick backup
subflows for plain transmissions.
Stale subflows can return in active state, as soon as any reply
from the peer is observed.
Active backup scenarios can now leverage the available b/w
with no restrinction.

The PM can close active subflow, e.g. due to ingress RM_ADDR
option. Such subflow could carry data still unacked at the
MPTCP-level, both in the write and the rtx_queue, which has
never reached the other peer.
Currently the mptcp-level retransmission will deliver such data,
but at a very low rate (at most 1 DSM for each MPTCP rtx interval).
We can speed-up the recovery a lot, moving all the unacked in the
tcp write_queue, so that it will be pushed again via other
subflows, at the speed allowed by them.

The 'imply' keyword does not do what most people think it does, it only
politely asks Kconfig to turn on another symbol, but does not prevent
it from being disabled manually or built as a loadable module when the
user is built-in. In the ICE driver, the latter now causes a link failure:

aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild':
This is a recurring problem in many drivers, and we have discussed
it several times befores, without reaching a consensus. I'm providing
a link to the previous email thread for reference, which discusses
some related problems.
To solve the dependency issue better than the 'imply' keyword, introduce a
separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver
can depend on if it is able to use PTP support when available, but works
fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are
then prevented from being built-in, the same way as with a 'depends on
PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick,
but that can be rather confusing when you first see it.
Since this should cover the dependencies correctly, the IS_REACHABLE()
hack in the header is no longer needed now, and can be turned back
into a normal IS_ENABLED() check. Any driver that gets the dependency
wrong will now cause a link time failure rather than being unable to use
PTP support when that is in a loadable module.
However, the two recently added ptp_get_vclocks_index() and
ptp_convert_timestamp() interfaces are only called from builtin code with
ethtool and socket timestamps, so keep the current behavior by stubbing
those out completely when PTP is in a loadable module. This should be
addressed properly in a follow-up.
As Richard suggested, we may want to actually turn PTP support into a
'bool' option later on, preventing it from being a loadable module
altogether, which would be one way to solve the problem with the ethtool
interface.

a reference to MICROBLAZE_64K_PAGES in the config VMXNET3 in
./drivers/net/Kconfig.
Remove this obsolete reference to config MICROBLAZE_64K_PAGES.

By default FEC driver treat irq[0] (i.e. int0 described in dt-binding) as
wakeup interrupt, but this situation changed on i.MX8M serials, SoC
integration guys mix wakeup interrupt signal into int2 interrupt line.
This patch introduces FEC_QUIRK_WAKEUP_FROM_INT2 to indicate int2 as wakeup
interrupt for i.MX8MQ.

The EtherAVB instances on the R-Car E3/D3 and RZ/G2E SoCs do not support
TX clock internal delay modes, and the EtherAVB driver prints a warning
if an unsupported "rgmii-*id" PHY mode is specified, to catch buggy
DTBs.
Commit a6f51f2efa ("ravb: Add support for explicit internal
clock delay configuration") deprecated deriving the internal delay mode
from the PHY mode, in favor of explicit configuration using the now
mandatory "rx-internal-delay-ps" and "tx-internal-delay-ps" properties,
thus delegating the warning to the legacy fallback code.
Since explicit configuration of a (valid) internal clock delay
configuration is enforced by validating device tree source files against
DT binding files, and all upstream DTS files have been converted as of
commit a5200e63af ("arm64: dts: renesas: rzg2: Convert EtherAVB to
explicit delay handling"), the checks in the legacy fallback code can be
removed.

The new vlan+srcmac xmit policy is not implementable with XDP since
in many cases the 802.1Q payload is not present in the packet. This
can be for example due to hardware offload or in the case of veth
due to use of skbuffs internally.
This also fixes the NULL deref with the vlan+srcmac xmit policy
reported by Jonathan Toppins by additionally checking the skb
pointer.

Pull networking fixes from Jakub Kicinski:
"Networking fixes, including fixes from netfilter, bpf, can and
ieee802154.
The size of this is pretty normal, but we got more fixes for 5.14
changes this week than last week. Nothing major but the trend is the
opposite of what we like. We'll see how the next week goes..
Current release - regressions:
- r8169: fix ASPM-related link-up regressions
- bridge: fix flags interpretation for extern learn fdb entries
- phy: micrel: fix link detection on ksz87xx switch
- Revert "tipc: Return the correct errno code"
- ptp: fix possible memory leak caused by invalid cast
Current release - new code bugs:
- bpf: add missing bpf_read_[un]lock_trace() for syscall program
- bpf: fix potentially incorrect results with bpf_get_local_storage()
- page_pool: mask the page->signature before the checking, avoid dma
mapping leaks
- netfilter: nfnetlink_hook: 5 fixes to information in netlink dumps
- bnxt_en: fix firmware interface issues with PTP
- mlx5: Bridge, fix ageing time
Previous releases - regressions:
- linkwatch: fix failure to restore device state across
suspend/resume
- bareudp: fix invalid read beyond skb's linear data
Previous releases - always broken:
- bpf: fix integer overflow involving bucket_size
- ppp: fix issues when desired interface name is specified via
netlink
- wwan: mhi_wwan_ctrl: fix possible deadlock
- dsa: microchip: ksz8795: fix number of VLAN related bugs
- dsa: drivers: fix broken backpressure in .port_fdb_dump
- dsa: qca: ar9331: make proper initial port defaults
Misc:
- bpf: add lockdown check for probe_write_user helper
- netfilter: conntrack: remove offload_pickup sysctl before 5.14 is
out
- netfilter: conntrack: collect all entries in one cycle,
heuristically slow down garbage collection scans on idle systems to
prevent frequent wake ups"
