The current mptcp re-inject strategy is very aggressive,
we have mptcp-level retransmissions even on single subflow
connection, if the link in-use is lossy.
Let's be a little more conservative: we do retransmit
only if at least a subflow has write and rtx queue empty.
Additionally use the backup subflows only if the active
subflows are stale - no progresses in at least an rtx period
and ignore stale subflows for rtx timeout update

As reported by Maxim, we have a lot of MPTCP-level
retransmissions when multilple links with different latencies
are in use.
This patch refactor the mptcp-level timeout accounting so that
the maximum of all the active subflow timeout is used. To avoid
traversing the subflow list multiple times, the update is
performed inside the packet scheduler.
Additionally clean-up a bit timeout handling.

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_eth_ioctl':
ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config'

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.

Add support for SFP cages connected to the Marvell 88E1512 transceiver.
88E1512 supports for SGMII/1000Base-X/100Base-FX media type with RGMII
on system interface. Configure PHY to appropriate mode depending on the
type of SFP inserted. On SFP removal configure PHY to the RGMII-copper

Lukas Bulwahn says:
====================
Kconfig symbol clean-up on net
The script ./scripts/checkkconfigsymbols.py warns on invalid references to
Kconfig symbols (often, minor typos, name confusions or outdated references).
This patch series addresses all issues reported by
./scripts/checkkconfigsymbols.py in ./net/ and ./drivers/net/ for Kconfig
and Makefile files. Issues in the Kconfig and Makefile files indicate some
shortcomings in the overall build definitions, and often are true actionable
issues to address.
These issues can be identified and filtered by:
./scripts/checkkconfigsymbols.py \
| grep -E "(drivers/)?net/.*(Kconfig|Makefile)" -B 1 -A 1
After applying this patch series on linux-next (next-20210811), the command
above yields no further issues to address.

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 a6f51f2efa742df0 ("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 a5200e63af57d05e ("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.

It isn't required, but all callers of ipa_aggr_granularity_val()
pass a constant value (IPA_AGGR_GRANULARITY) as the usec argument.
Two of those callers are in ipa_validate_build(), with the result
being passed to BUILD_BUG_ON().
Evidently the "sparc64-linux-gcc" compiler (at least) doesn't always
inline ipa_aggr_granularity_val(), so the result of the function is
not constant at compile time, and that leads to build errors.
Define the function with the __always_inline attribute to avoid the
errors. We can see by inspection that the value passed is never
zero, so we can just remove its WARN_ON() call.

There's a potential deadlock case when remove the vsock device or
process the RESET event:
vsock_for_each_connected_socket:
spin_lock_bh(&vsock_table_lock) ----------- (1)
...
virtio_vsock_reset_sock:
lock_sock(sk) --------------------- (2)
...
spin_unlock_bh(&vsock_table_lock)
lock_sock() may do initiative schedule when the 'sk' is owned by
other thread at the same time, we would receivce a warning message
that "scheduling while atomic".
Even worse, if the next task (selected by the scheduler) try to
release a 'sk', it need to request vsock_table_lock and the deadlock
occur, cause the system into softlockup state.
Call trace:
queued_spin_lock_slowpath
vsock_remove_bound
vsock_remove_sock
virtio_transport_release
__vsock_release
vsock_release
__sock_release
sock_close
__fput
____fput
So we should not require sk_lock in this case, just like the behavior
in vhost_vsock or vmci.

Pull ucounts fix from Eric Biederman:
"This fixes the ucount sysctls on big endian architectures.
The counts were expanded to be longs instead of ints, and the sysctl
code was overlooked, so only the low 32bit were being processed. On
litte endian just processing the low 32bits is fine, but on 64bit big
endian processing just the low 32bits results in the high order bits
instead of the low order bits being processed and nothing works
proper.
This change took a little bit to mature as we have the SYSCTL_ZERO,
and SYSCTL_INT_MAX macros that are only usable for sysctls operating
on ints, but unfortunately are not obviously broken. Which resulted in
the versions of this change working on big endian and not on little
endian, because the int SYSCTL_ZERO when extended 64bit wound up being
0x100000000. So we only allowed values greater than 0x100000000 and
less than 0faff. Which unfortunately broken everything that tried to
set the sysctls. (First reported with the windows subsystem for
linux).
I have tested this on x86_64 64bit after first reproducing the
problems with the earlier version of this change, and then verifying
the problems do not exist when we use appropriate long min and max
values for extra1 and extra2"

Improvements to the DSA tag_8021q cross-chip notifiers

Currently, on my board with multiple sja1105 switches in disjoint trees
described in commit f66a6a69f97a ("net: dsa: permit cross-chip bridging
between all trees in the system"), rebooting the board triggers the
following benign warnings:
[ 12.345566] sja1105 spi2.0: port 0 failed to notify tag_8021q VLAN 1088 deletion: -ENOENT
[ 12.353804] sja1105 spi2.0: port 0 failed to notify tag_8021q VLAN 2112 deletion: -ENOENT
[ 12.362019] sja1105 spi2.0: port 1 failed to notify tag_8021q VLAN 1089 deletion: -ENOENT
[ 12.370246] sja1105 spi2.0: port 1 failed to notify tag_8021q VLAN 2113 deletion: -ENOENT
[ 12.378466] sja1105 spi2.0: port 2 failed to notify tag_8021q VLAN 1090 deletion: -ENOENT
[ 12.386683] sja1105 spi2.0: port 2 failed to notify tag_8021q VLAN 2114 deletion: -ENOENT
Basically switch 1 calls dsa_tag_8021q_unregister, and switch 1's TX and
RX VLANs cannot be found on switch 2's CPU port.
But why would switch 2 even attempt to delete switch 1's TX and RX
tag_8021q VLANs from its CPU port? Well, because we use dsa_broadcast,
and it is supposed that it had added those VLANs in the first place
(because in dsa_port_tag_8021q_vlan_match, all CPU ports match
regardless of their tree index or switch index).
The two trees probe asynchronously, and when switch 1 probed, it called
dsa_broadcast which did not notify the tree of switch 2, because that
didn't probe yet. But during unbind, switch 2's tree _is_ probed, so it
_is_ notified of the deletion.
Before jumping to introduce a synchronization mechanism between the
probing across disjoint switch trees, let's take a step back and see
whether we _need_ to do that in the first place.
The RX and TX VLANs of switch 1 would be needed on switch 2's CPU port
only if switch 1 and 2 were part of a cross-chip bridge. And
dsa_tag_8021q_bridge_join takes care precisely of that (but if probing
was synchronous, the bridge_join would just end up bumping the VLANs'
refcount, because they are already installed by the setup path).
Since by the time the ports are bridged, all DSA trees are already set
up, and we don't need the tag_8021q VLANs of one switch installed on the
other switches during probe time, the answer is that we don't need to
fix the synchronization issue.
So make the setup and teardown code paths call dsa_port_notify, which
notifies only the local tree, and the bridge code paths call
dsa_broadcast, which let the other trees know as well.

This mistake went unnoticed because until recently we were using the

offset was corrected, we started hitting errors like

The overtemperature bit is set if package temperature is beyond 155C°.
This functionality was tested by heating the package up to 200C°
The undervoltage bit is set if supply voltage drops beyond some critical
threshold. Currently not tested.
In a typical use case, both of this events should be logged and stored

====================
pktgen: Add IMIX mode
Adds internet mix (IMIX) mode to pktgen. Internet mix is
included in many user-space network perf testing tools. It allows
for the user to specify a distribution of discrete packet sizes to be
generated. This type of test is common among vendors when perf testing
their devices.
[RFC link: https://datatracker.ietf.org/doc/html/rfc2544#section-9.1]
This allows users to get a
more complete picture of how their device will perform in the
real-world.
This feature adds a command that allows users to specify an imix
distribution in the following format:
imix_weights size_1,weight_1 size_2,weight_2 ... size_n,weight_n
The distribution of packets with size_i will be
(weight_i / total_weights) where
total_weights = weight_1 + weight_2 + ... + weight_n
For example:
imix_weights 40,7 576,4 1500,1
The pkt_size "40" will account for 7 / (7 + 4 + 1) = ~58% of the total
packets sent.
This patch was tested with the following:
1. imix_weights = 40,7 576,4 1500,1
2. imix_weights = 0,7 576,4 1500,1
- Packet size of 0 is resized to the minimum, 42
3. imix_weights = 40,7 576,4 1500,1 count = 0
- Zero count.
- Runs until user stops pktgen.
Invalid Configurations
1. clone_skb = 200 imix_weights = 40,7 576,4 1500,1
- Returns error code -524 (-ENOTSUPP) when setting imix_weights
2. len(imix_weights) > MAX_IMIX_ENTRIES
- Returns -7 (-E2BIG)
This patch is split into three parts, each provide different aspects of
required functionality:
1. Parse internet mix input.
2. Add IMIX Distribution representation.
3. Process and output IMIX results.
Changes in v2:
* Remove __ prefix outside of uAPI.
* Use seq_puts instead of seq_printf where necessary.
* Reorder variable declaration.
* Return -EINVAL instead of -ENOTSUPP when using IMIX with clone_skb > 0

In order to represent the distribution of imix packet sizes, a
pre-computed data structure is used. It features 100 (IMIX_PRECISION)
"bins". Contiguous ranges of these bins represent the respective
packet size of each imix entry. This is done to avoid the overhead of
selecting the correct imix packet size based on the corresponding weights.
Example:
imix_weights 40,7 576,4 1500,1
total_weight = 7 + 4 + 1 = 12
pkt_size 40 occurs 7/total_weight = 58% of the time
pkt_size 576 occurs 4/total_weight = 33% of the time
pkt_size 1500 occurs 1/total_weight = 9% of the time
We generate a random number between 0-100 and select the corresponding
packet size based on the specified weights.
Eg. random number = 358723895 % 100 = 65
Selects the packet size corresponding to index:65 in the pre-computed
imix_distribution array.
An example of the pre-computed array is below:
The imix_distribution will look like the following:
0 -> 0 (index of imix_entry.size == 40)
1 -> 0 (index of imix_entry.size == 40)
2 -> 0 (index of imix_entry.size == 40)
[...] -> 0 (index of imix_entry.size == 40)
57 -> 0 (index of imix_entry.size == 40)
58 -> 1 (index of imix_entry.size == 576)
[...] -> 1 (index of imix_entry.size == 576)
90 -> 1 (index of imix_entry.size == 576)
91 -> 2 (index of imix_entry.size == 1500)
[...] -> 2 (index of imix_entry.size == 1500)
99 -> 2 (index of imix_entry.size == 1500)
Create and use "bin" representation of the imix distribution.

Adds "imix_weights" command for specifying internet mix distribution.
The command is in this format:
"imix_weights size_1,weight_1 size_2,weight_2 ... size_n,weight_n"
where the probability that packet size_i is picked is:
weight_i / (weight_1 + weight_2 + .. + weight_n)
The user may provide up to 100 imix entries (size_i,weight_i) in this
command.
The user specified imix entries will be displayed in the "Params"
section of the interface output.
Values for clone_skb > 0 is not supported in IMIX mode.
Summary of changes:
Add flag for enabling internet mix mode.
Add command (imix_weights) for internet mix input.
Return -ENOTSUPP when clone_skb > 0 in IMIX mode.
