bridge: mcast: Do not derive entry type from its filter mode
Currently, the filter mode (i.e., INCLUDE / EXCLUDE) of MDB entries
cannot be set from user space. Instead, it is set by the kernel
according to the entry type: (*, G) entries are treated as EXCLUDE and
(S, G) entries are treated as INCLUDE. This allows the kernel to derive
the entry type from its filter mode.
Subsequent patches will allow user space to set the filter mode of (*,
G) entries, making the current assumption incorrect.
As a preparation, remove the current assumption and instead determine
the entry type from its key, which is a more direct way.

Currently, in bonding it reused the IFF_SLAVE flag and checked it
in ipv6 addrconf to prevent ipv6 addrconf.
However, it is not a proper flag to use for no ipv6 addrconf, for
bonding it has to move IFF_SLAVE flag setting ahead of dev_open()

used in bonding and eql, as Jiri mentioned, the new devices like
Team, Failover do not use this flag.

net: dsa: mv88e6xxx: read FID when handling ATU violations
When an ATU violation occurs, the switch uses the ATU FID register to
report the FID of the MAC address that incurred the violation. It would
be good for the driver to know the FID value for purposes such as
logging and CPU-based authentication.
Up until now, the driver has been calling the mv88e6xxx_g1_atu_op()
function to read ATU violations, but that doesn't do exactly what we
want, namely it calls mv88e6xxx_g1_atu_fid_write() with FID 0.
(side note, the documentation for the ATU Get/Clear Violation command
says that writes to the ATU FID register have no effect before the
operation starts, it's only that we disregard the value that this
register provides once the operation completes)
So mv88e6xxx_g1_atu_fid_write() is not what we want, but rather
mv88e6xxx_g1_atu_fid_read(). However, the latter doesn't exist, we need
to write it.
The remainder of mv88e6xxx_g1_atu_op() except for
mv88e6xxx_g1_atu_fid_write() is still needed, namely to send a
GET_CLR_VIOLATION command to the ATU. In principle we could have still
kept calling mv88e6xxx_g1_atu_op(), but the MDIO writes to the ATU FID
register are pointless, but in the interest of doing less CPU work per
interrupt, write a new function called mv88e6xxx_g1_read_atu_violation()
and call it.
The FID will be the port default FID as set by mv88e6xxx_port_set_fid()
if the VID from the packet cannot be found in the VTU. Otherwise it is
the FID derived from the VTU entry associated with that VID.

from Li Qiong.
7) A large batch of IPVS updates to replace timer-based estimators by
kthreads to scale up wrt. CPUs and workload (millions of estimators).
Julian Anastasov says:
This patchset implements stats estimation in kthread context.
It replaces the code that runs on single CPU in timer context every 2
seconds and causing latency splats as shown in reports [1], [2], [3].
The solution targets setups with thousands of IPVS services,
destinations and multi-CPU boxes.
Spread the estimation on multiple (configured) CPUs and multiple
time slots (timer ticks) by using multiple chains organized under RCU
rules. When stats are not needed, it is recommended to use
run_estimation=0 as already implemented before this change.
RCU Locking:
- As stats are now RCU-locked, tot_stats, svc and dest which
hold estimator structures are now always freed from RCU
callback. This ensures RCU grace period after the
ip_vs_stop_estimator() call.
Kthread data:
- every kthread works over its own data structure and all
such structures are attached to array. For now we limit
kthreads depending on the number of CPUs.
- even while there can be a kthread structure, its task
may not be running, eg. before first service is added or
while the sysctl var is set to an empty cpulist or
when run_estimation is set to 0 to disable the estimation.
- the allocated kthread context may grow from 1 to 50
allocated structures for timer ticks which saves memory for
setups with small number of estimators
- a task and its structure may be released if all
estimators are unlinked from its chains, leaving the
slot in the array empty
- every kthread data structure allows limited number
of estimators. Kthread 0 is also used to initially
calculate the max number of estimators to allow in every
chain considering a sub-100 microsecond cond_resched
rate. This number can be from 1 to hundreds.
- kthread 0 has an additional job of optimizing the
adding of estimators: they are first added in
temp list (est_temp_list) and later kthread 0
distributes them to other kthreads. The optimization
is based on the fact that newly added estimator
should be estimated after 2 seconds, so we have the
time to offload the adding to chain from controlling
process to kthread 0.
- to add new estimators we use the last added kthread
context (est_add_ktid). The new estimators are linked to
the chains just before the estimated one, based on add_row.
This ensures their estimation will start after 2 seconds.
If estimators are added in bursts, common case if all
services and dests are initially configured, we may
spread the estimators to more chains and as result,
reducing the initial delay below 2 seconds.
Many thanks to Jiri Wiesner for his valuable comments
and for spending a lot of time reviewing and testing
the changes on different platforms with 48-256 CPUs and
1-8 NUMA nodes under different cpufreq governors.
The new IPVS estimators do not use workqueue infrastructure
because:
- The estimation can take long time when using multiple IPVS rules (eg.
millions estimator structures) and especially when box has multiple
CPUs due to the for_each_possible_cpu usage that expects packets from
any CPU. With est_nice sysctl we have more control how to prioritize the
estimation kthreads compared to other processes/kthreads that have
latency requirements (such as servers). As a benefit, we can see these
kthreads in top and decide if we will need some further control to limit
their CPU usage (max number of structure to estimate per kthread).
- with kthreads we run code that is read-mostly, no write/lock
operations to process the estimators in 2-second intervals.
- work items are one-shot: as estimators are processed every
2 seconds, they need to be re-added every time. This again
loads the timers (add_timer) if we use delayed works, as there are
no kthreads to do the timings.

Bluetooth: virtio_bt: fix device removal
Device removal is clearly out of virtio spec: it attempts to remove
unused buffers from a VQ before invoking device reset. To fix, make
open/close NOPs and do all cleanup/setup in probe/remove.
NB: This is a hacky way to handle this - virtbt_{open,close} as NOP is
not really what a driver is supposed to be doing. These are transport
enable/disable callbacks from the BT core towards the driver. It maps to
a device being enabled/disabled by something like bluetoothd for
example. So if disabled, users expect that no resources/queues are in
use. It does work with all other transports like USB, SDIO, UART etc.
There should be no buffer used if the device is powered off. We also
don’t have any USB URBs in-flight if the transport is not active.
The way to implement a proper fix would be using vq reset if supported,
or even using a full device reset.
The cost of the hack is a single skb wasted on an unused bt device.
NB2: with this fix in place driver still suffers from a race condition
if an interrupt triggers while device is being reset. To fix, in the
virtbt_close() callback we should deactivate all interrupts. To be
fixed.

Bluetooth: Work around SCO over USB HCI design defect
The USB interface between the host and the bluetooth adapter used for
SCO packets uses an USB isochronous endpoint with a fragmentation scheme
that does not tolerate errors. Except USB isochronous transfers do
not provide a reliable stream with guaranteed delivery. (There is no
retry on error, see USB spec v2.0 5.6 and 8.5.5.)
To fragment a packet, the bluetooth HCI simply splits it in parts and
transfer them as-is. The receiver is expected to reconstruct the packet
by assuming the first fragment contains the header and parsing its size
field. There is no error detection either.
If a fragment is lost, the end result is that the kernel is no longer
synchronized and will pass malformed data to the upper layers, since it
has no way to tell if the first fragment is an actual first fragment or
a continuation fragment. Resynchronization can only happen by luck and
requires an unbounded amount of time.
The typical symptom for a HSP/HFP bluetooth headset is that the
microphone stops working and dmesg contains piles of rate-limited
"Bluetooth: hci0: SCO packet for unknown connection handle XXXX"
errors for an indeterminate amount of time, until the kernel accidentally
resynchronize.
A workaround is to ask the upper layer to prevalidate the first fragment
header. This is not possible with user channels so this workaround is
disabled in this case.
This problem is the most severe when using an ath3k adapter on an i.MX 6
board, where packet loss occur regularly, possibly because it is an USB1
device connected on an USB2 hub and this is a special case requiring
split transactions.

sctp: sysctl: make extra pointers netns aware
Recently, a customer reported that from their container whose
net namespace is different to the host's init_net, they can't set
the container's net.sctp.rto_max to any value smaller than
init_net.sctp.rto_min.
For instance,
Host:
sudo sysctl net.sctp.rto_min
net.sctp.rto_min = 1000
Container:
echo 100 > /mnt/proc-net/sctp/rto_min
echo 400 > /mnt/proc-net/sctp/rto_max
echo: write error: Invalid argument
This is caused by the check made from this'commit
4f3fdf3bc59c
("sctp: add check rto_min and rto_max in sysctl")'
When validating the input value, it's always referring the boundary
value set for the init_net namespace.
Having container's rto_max smaller than host's init_net.sctp.rto_min
does make sense. Consider that the rto between two containers on the
same host is very likely smaller than it for two hosts.
So to fix this problem, as suggested by Marcelo, this patch makes the
extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point
to the corresponding variables from the newly created net namespace while
the new net namespace is being registered in sctp_sysctl_net_register.

Merge patch series "can: etas_es58x: report firmware, bootloader and hardware version"
Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:
The goal of this series is to report the firmware version, the
bootloader version and the hardware revision of ETAS ES58x devices.
These are already reported in the kernel log but this isn't best
practice. Remove the kernel log and instead export all these through
devlink. The devlink core automatically exports the firmware and the
bootloader version to ethtool, so no need to implement the
ethtool_ops::get_drvinfo() callback anymore.
Patch one and two implement the core support for devlink (at device
level) and devlink port (at the network interface level).
Patch three export usb_cache_string() and patch four add a new info
attribute to devlink.h. Both are prerequisites for patch five.
Patch five is the actual goal: it parses the product information from
a custom usb string returned by the device and expose them through
devlink.
Patch six removes the product information from the kernel log.
Finally, patch seven add a devlink documentation page with list all
the information attributes reported by the driver.

* Changelog *
v4 -> v5: https://lore.kernel.org/all/
20221130174658.29282-1-mailhol.vincent@wanadoo.fr
* [PATH 2/7] add devlink port support. This extends devlink to the
network interface.
* thanks to devlink port, 'ethtool -i' is now able to retrieve the
firmware version from devlink. No need to implement the
ethtool_ops::get_drvinfo() callback anymore: remove one patch from
the series.
* [PATCH 4/7] A new patch to add a new info attribute for the
bootloader version in devlink.h. This patch was initially sent as
a standalone patch here:
https://lore.kernel.org/netdev/
20221129031406.3849872-1-mailhol.vincent@wanadoo.fr
Merging it to this series so that it is both added and used at the
same time.
* [PATCH 5/7] use the newly info attribute defined in patch 4/7 to
report the bootloader version instead of the custom string "bl".
* [PATCH 5/7] because the series does not implement
ethtool_ops::get_drvinfo() anymore, the two helper functions
es58x_sw_version_is_set() and es58x_hw_revision_is_set() are only
used in devlink.c. Move them from es58x_core.h to es58x_devlink.c.
* [PATCH 5/7] small rework of the helper function
es58x_hw_revision_is_set(): it is OK to only check the letter (if
the letter is '\0', it will not be possible to print the next
numbers).
* [PATCH 5/7 and 6/7] add reviewed-by Andrew Lunn tag.
* [PATCH 7/7] Now, 'ethtool -i' reports both the firmware version
and the bootloader version (this is how the core export the
information from devlink to ethtool). Update the documentation to
reflect this fact.
* Reoder the patches.
v3 -> v4: https://lore.kernel.org/all/
20221126162211.93322-1-mailhol.vincent@wanadoo.fr
* major rework to use devlink instead of sysfs following Andrew's
comment.
* split the series in 6 patches.
* [PATCH 1/6] add Acked-by: Greg Kroah-Hartman
v2 -> v3: https://lore.kernel.org/all/
20221113040108.68249-1-mailhol.vincent@wanadoo.fr
* patch 2/3: do not spam the kernel log anymore with the product
number. Instead parse the product information string, extract the
firmware version, the bootloadar version and the hardware revision
and export them through sysfs.
* patch 2/3: rework the parsing in order not to need additional
fields in struct es58x_parameters.
* patch 3/3: only populate ethtool_drvinfo::fw_version because since
commit
edaf5df22cb8 ("ethtool: ethtool_get_drvinfo: populate
drvinfo fields even if callback exits"), there is no need to
populate ethtool_drvinfo::driver and ethtool_drvinfo::bus_info in
the driver.
v1 -> v2: https://lore.kernel.org/all/
20221104171604.24052-1-mailhol.vincent@wanadoo.fr
* was a single patch. It is now a series of three patches.
* add a first new patch to export usb_cache_string().
* add a second new patch to apply usb_cache_string() to existing code.
* add missing check on product info string to prevent a buffer overflow.
* add comma on the last entry of struct es58x_parameters.
