rxrpc: Fix overproduction of wakeups to recvmsg()
Fix three cases of overproduction of wakeups:
(1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
data for recvmsg() to collect if it queues some data - and then its
only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.
Fix the rxrpc_input_data() to only do the wakeup in failure cases.
(2) If a DATA packet is received for a call by the I/O thread whilst
recvmsg() is busy draining the call's rx queue in the app thread, the
call will left on the recvmsg() queue for recvmsg() to pick up, even
though there isn't any data on it.
This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
set after the reply has been posted to a service call.
Fix this by discarding pending calls from the recvmsg() queue that
don't need servicing yet.
(3) Not-yet-completed calls get requeued after having data read from them,
even if they have no data to read.
Fix this by only requeuing them if they have data waiting on them; if
they don't, the I/O thread will requeue them when data arrives or they
fail.

====================
net: final GSI register updates
I believe this is the last set of changes required to allow IPA v5.0
to be supported. There is a little cleanup work remaining, but that
can happen in the next Linux release cycle. Otherwise we just need
config data and register definitions for IPA v5.0 (and DTS updates).
These are ready but won't be posted without further testing.
The first patch in this series fixes a minor bug in a patch just
posted, which I found too late. The second eliminates the GSI
memory "adjustment"; this was done previously to avoid/delay the
need to implement a more general way to define GSI register offsets.
Note that this patch causes "checkpatch" warnings due to indentation
that aligns with an open parenthesis.
The third patch makes use of the newly-defined register offsets, to
eliminate the need for a function that hid a few details. The next
modifies a different helper function to work properly for IPA v5.0+.
The fifth patch changes the way the event ring size is specified
based on how it's now done for IPA v5.0+. And the last defines a
new register required for IPA v5.0+.

net: ipa: kill gsi->virt_raw
Starting at IPA v4.5, almost all GSI registers had their offsets
changed by a fixed amount (shifted downward by 0xd000). Rather than
defining offsets for all those registers dependent on version, an
adjustment was applied for most register accesses. This was
implemented in commit
cdeee49f3ef7f ("net: ipa: adjust GSI register
addresses"). It was later modified to be a bit more obvious about
the adjusment, in commit
571b1e7e58ad3 ("net: ipa: use a separate
pointer for adjusted GSI memory").
We now are able to define every GSI register with its own offset, so
there's no need to implement this special adjustment.
So get rid of the "virt_raw" pointer, and just maintain "virt" as
the (non-adjusted) base address of I/O mapped GSI register memory.
Redefine the offsets of all GSI registers (other than the INTER_EE
ones, which were not subject to the adjustment) for IPA v4.5+,
subtracting 0xd000 from their defined offsets instead.
Move the ERROR_LOG and ERROR_LOG_CLR definitions further down in the
register definition files so all registers are defined in order of
their offset.

====================
seg6: add PSP flavor support for SRv6 End behavior
Segment Routing for IPv6 (SRv6 in short) [1] is the instantiation of the
Segment Routing (SR) [2] architecture on the IPv6 dataplane.
In SRv6, the segment identifiers (SID) are IPv6 addresses and the segment list
(SID List) is carried in the Segment Routing Header (SRH). A segment may be
bound to a specific packet processing operation called "behavior". The RFC8986
[3] defines and standardizes the most common/relevant behaviors for network
operators, e.g., End, End.X and End.T and so on.
The RFC8986 also introduces the "flavors" framework aiming to modify or extend
the capabilities of SRv6 End, End.X and End.T behaviors. Specifically, these
behaviors support the following flavors (either individually or in
combinations):
- Penultimate Segment Pop (PSP);
- Ultimate Segment Pop (USP);
- Ultimate Segment Decapsulation (USD).
Such flavors enable an End/End.X/End.T behavior to pop the SRH on the
penultimate/ultimate SR endpoint node listed in the SID List or to perform a
full decapsulation.
Currently, the Linux kernel supports a large subset of behaviors described in
RFC8986, including the End, End.X and End.T. However, PSP, USP and USD flavors
have not yet been implemented.
In this patchset, we extend the SRv6 subsystem to implement the PSP flavor in
the SRv6 End behavior. To accomplish this task, we leverage the flavor
framework previously introduced by another patchset required for supporting the
efficient representation of the SID List through the NEXT-C-SID mechanism [4].
In details, the patchset is made of:
- patch 1/3: seg6: factor out End lookup nexthop processing to a dedicated
function
- patch 2/3: seg6: add PSP flavor support for SRv6 End behavior
- patch 3/3: selftests: seg6: add selftest for PSP flavor in SRv6 End
behavior
From the user space perspective, we do not need to change the iproute2 code to
support the PSP flavor. However, we provide the man page for the PSP flavor in
a separate patch.
Comments, improvements and suggestions are always appreciated.

It instantiates a virtual network composed of several nodes: hosts and

properly interconnected to others through veth pairs.
The test makes use of the SRv6 End behavior and of the PSP flavor needed
for removing the SRH from the IPv6 header at the penultimate node.
The correct execution of the behavior is verified through reachability

- Penultimate Segment Pop (PSP);
- Ultimate Segment Pop (USP);
- Ultimate Segment Decapsulation (USD).
Depending on how the Segment Routing Header (SRH) has to be handled, an
SRv6 End* behavior can support these flavors either individually or in
combinations.
In this patch, we only consider the PSP flavor for the SRv6 End behavior.
A PSP enabled SRv6 End behavior is used by the Source/Ingress SR node
(i.e., the one applying the SRv6 Policy) when it needs to instruct the
penultimate SR Endpoint node listed in the SID List (carried by the SRH) to
remove the SRH from the IPv6 header.
Specifically, a PSP enabled SRv6 End behavior processes the SRH by:
i) decreasing the Segment Left (SL) from 1 to 0;
ii) copying the Last Segment IDentifier (SID) into the IPv6 Destination
Address (DA);
iii) removing (i.e., popping) the outer SRH from the extension headers
following the IPv6 header.
It is important to note that PSP operation (steps i, ii, iii) takes place
only at a penultimate SR Segment Endpoint node (i.e., when the SL=1) and
does not happen at non-penultimate Endpoint nodes. Indeed, when a SID of
PSP flavor is processed at a non-penultimate SR Segment Endpoint node, the
PSP operation is not performed because it would not be possible to decrease
the SL from 1 to 0.
SL=2 SL=1 SL=0
| | |
For example, given the SRv6 policy (SID List := < X, Y, Z >):
- a PSP enabled SRv6 End behavior bound to SID "Y" will apply the PSP
operation as Segment Left (SL) is 1, corresponding to the Penultimate
Segment of the SID List;
- a PSP enabled SRv6 End behavior bound to SID "X" will *NOT* apply the
PSP operation as the Segment Left is 2. This behavior instance will
apply the "standard" End packet processing, ignoring the configured PSP
flavor at all.

====================
sfc: devlink support for ef100
This patchset adds devlink port support for ef100 allowing setting VFs
mac addresses through the VF representor devlink ports.
Basic devlink infrastructure is first introduced, then support for info
command. Next changes for enumerating MAE ports which will be used for
devlink port creation when netdevs are registered.
Adding support for devlink port_function_hw_addr_get requires changes in
the ef100 driver for getting the mac address based on a client handle.
This allows to obtain VFs mac addresses during netdev initialization as
well what is included in patch 6.
Such client handle is used in patches 7 and 8 for getting and setting
devlink port addresses.

devlink: Fix netdev notifier chain corruption
Cited commit changed devlink to register its netdev notifier block on
the global netdev notifier chain instead of on the per network namespace
one.
However, when changing the network namespace of the devlink instance,
devlink still tries to unregister its notifier block from the chain of
the old namespace and register it on the chain of the new namespace.
This results in corruption of the notifier chains, as the same notifier
block is registered on two different chains: The global one and the per
network namespace one. In turn, this causes other problems such as the
inability to dismantle namespaces due to netdev reference count issues.
Fix by preventing devlink from moving its notifier block between
namespaces.

net/sched: transition actions to pcpu stats and rcu
Following the work done for act_pedit[0], transition the remaining tc
actions to percpu stats and rcu, whenever possible.
Percpu stats make updating the action stats very cheap, while combining
it with rcu action parameters makes it possible to get rid of the per
action lock in the datapath.
For act_connmark and act_nat we run the following tests:
- tc filter add dev ens2f0 ingress matchall action connmark
- tc filter add dev ens2f0 ingress matchall action nat ingress any 10.10.10.10
Our setup consists of a 26 cores Intel CPU and a 25G NIC.
We use TRex to shoot 10mpps TCP packets and take perf measurements.
Both actions improved performance as expected since the datapath lock disappeared.
For act_pedit we move the drop counter to percpu, when available.
For act_gate we move the counters to percpu, when available.

net/sched: Retire some tc qdiscs and classifiers
The CBQ + dsmark qdiscs and the tcindex + rsvp classifiers have served us for
over 2 decades. Unfortunately, they have not been getting much attention due
to reduced usage. While we dont have a good metric for tabulating how much use
a specific kernel feature gets, for these specific features we observed that
some of the functionality has been broken for some time and no users complained.
In addition, syzkaller has been going to town on most of these and finding
issues; and while we have been fixing those issues, at times it becomes obvious
that we would need to perform bigger surgeries to resolve things found while
getting a syzkaller fix in place. After some discussion we feel that in order
to reduce the maintenance burden it is best to retire them.
This patchset leaves the UAPI alone. I could send another version which deletes
the UAPI as well. AFAIK, this has not been done before - so it wasnt clear what
how to handle UAPI. It seems legit to just delete it but we would need to
coordinate with iproute2 (given they sync up with kernel uapi headers). There
are probably other users we don't know of that copy kernel headers.
If folks feel differently I will resend the patches deleting UAPI for these
qdiscs and classifiers.
I will start another thread on iproute2 before sending any patches to iproute2.

Steen Hegelund says:
====================
Adding Sparx5 ES0 VCAP support
This provides the Egress Stage 0 (ES0) VCAP (Versatile Content-Aware
Processor) support for the Sparx5 platform.
The ES0 VCAP is an Egress Access Control VCAP that uses frame keyfields and
previously classified keyfields to add, rewrite or remove VLAN tags on the
egress frames, and is therefore often referred to as the rewriter.
The ES0 VCAP also supports trapping frames to the host.
The ES0 VCAP has 1 lookup accessible with this chain id:
- chain
10000000: ES0 Lookup 0
The ES0 VCAP does not do traffic classification to select a keyset, but it
does have two keysets that can be used on all traffic. For now only the
ISDX keyset is used.
The ES0 VCAP can match on an ISDX key (Ingress Service Index) as one of the
frame metadata keyfields, similar to the ES2 VCAP.
The ES0 VCAP uses external counters in the XQS (statistics) group.

igb: conditionalize I2C bit banging on external thermal sensor support
Commit
a97f8783a937 ("igb: unbreak I2C bit-banging on i350") introduced
code to change I2C settings to bit banging unconditionally.
However, this patch introduced a regression: On an Intel S2600CWR
Server Board with three NICs:
- 1x dual-port copper
Intel I350 Gigabit Network Connection [8086:1521] (rev 01)
fw 1.63, 0x80000dda
- 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ
Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01)
fw 1.52.0
the SFP NICs no longer get link at all. Reverting commit
a97f8783a937
or switching to the Intel out-of-tree driver both fix the problem.
Per the igb out-of-tree driver, I2C bit banging on i350 depends on
support for an external thermal sensor (ETS). However, commit
a97f8783a937 added bit banging unconditionally. Additionally, the
out-of-tree driver always calls init_thermal_sensor_thresh on probe,
while our driver only calls init_thermal_sensor_thresh only in
igb_reset(), and only if an ETS is present, ignoring the internal
thermal sensor. The affected SFPs don't provide an ETS. Per Intel,
the behaviour is a result of i350 firmware requirements.
This patch fixes the problem by aligning the behaviour to the
out-of-tree driver:
- split igb_init_i2c() into two functions:
- igb_init_i2c() only performs the basic I2C initialization.
- igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set
and enables bit-banging.
- igb_probe() only calls igb_set_i2c_bb() if an ETS is present.
- igb_probe() calls init_thermal_sensor_thresh() unconditionally.
- igb_reset() aligns its behaviour to igb_probe(), i. e., call
igb_set_i2c_bb() if an ETS is present and call
init_thermal_sensor_thresh() unconditionally.

====================
mlx5-updates-2023-02-10
1) From Roi and Mark: MultiPort eswitch support
MultiPort E-Switch builds on newer hardware's capabilities and introduces
a mode where a single E-Switch is used and all the vports and physical
ports on the NIC are connected to it.
The new mode will allow in the future a decrease in the memory used by the
driver and advanced features that aren't possible today.
This represents a big change in the current E-Switch implantation in mlx5.
Currently, by default, each E-Switch manager manages its E-Switch.
Steering rules in each E-Switch can only forward traffic to the native
physical port associated with that E-Switch. While there are ways to target
non-native physical ports, for example using a bond or via special TC
rules. None of the ways allows a user to configure the driver
to operate by default in such a mode nor can the driver decide
to move to this mode by default as it's user configuration-driven right now.
While MultiPort E-Switch single FDB mode is the preferred mode, older
generations of ConnectX hardware couldn't support this mode so it was never
implemented. Now that there is capable hardware present, start the
transition to having this mode by default.
Introduce a devlink parameter to control MultiPort Eswitch single FDB mode.
This will allow users to select this mode on their system right now
and in the future will allow the driver to move to this mode by default.

apparmor: Fix regression in compat permissions for getattr
This fixes a regression in mediation of getattr when old policy built
under an older ABI is loaded and mapped to internal permissions.
The regression does not occur for all getattr permission requests,
only appearing if state zero is the final state in the permission
lookup. This is because despite the first state (index 0) being
guaranteed to not have permissions in both newer and older permission
formats, it may have to carry permissions that were not mediated as
part of an older policy. These backward compat permissions are
mapped here to avoid special casing the mediation code paths.
Since the mapping code already takes into account backwards compat
permission from older formats it can be applied to state 0 to fix
the regression.
