Add checks in the XDP redirect callback to prevent XDP from running when
the TX ring is undergoing shutdown.
Also remove redundant checks in the XDP redirect callback to validate the
txr and the flag that indicates the ring supports XDP. The modulo
arithmetic on 'tx_nr_rings_xdp' already guarantees the derived TX
ring is an XDP ring. txr is also guaranteed to be valid after checking
BNXT_STATE_OPEN and within RCU grace period.

Insufficient space was being reserved in the page used for packet
reception, so the interface MTU could be set too large to still have
room for the contents of the packet when doing XDP redirect. This
resulted in the following message when redirecting a packet between
3520 and 3822 bytes with an MTU of 3822:

If there are more CPUs than the number of TX XDP rings, multiple XDP
redirects can select the same TX ring based on the CPU on which
XDP redirect is called. Add locking when needed and use static

To fix a coverity complain, commit d5ac07dfbd2b
("qed: Initialize debug string array") removed "sw-platform"
(one of the common global parameters) from the dump as this
was used in the dump with an uninitialized string, however
it did not reduce the number of common global parameters
which caused the incorrect (unable to parse) register dump
this patch fixes it with reducing NUM_COMMON_GLOBAL_PARAMS
bye one.

When the PHY and the MAC are capable of doing timestamping, the PHY has
priority. Therefore the DT option lan8814,ignore-ts was added such that
the PHY will not expose a PHC so then the timestamping was done in the
MAC. This is not the correct approach of doing it, therefore remove
this.

In commit 9cbadf094d9d ("net: stmmac: support max-speed device tree
property"), when DT platforms don't set "max-speed", max_speed is set to
-1; for non-DT platforms, it stays the default 0.
Prior to commit eeef2f6b9f6e ("net: stmmac: Start adding phylink support"),
the check for a valid max_speed setting was to check if it was greater
than zero. This commit got it right, but subsequent patches just checked
for non-zero, which is incorrect for DT platforms.
In commit 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()")
the conversion switched completely to checking for non-zero value as a
valid value, which caused 1000base-T to stop getting advertised by
default.
Instead of trying to fix all the checks, simply leave max_speed alone if
DT property parsing fails.

Handling of all-multicast flag and associated multicast promiscuous
mode is broken in ice driver. When an user switches allmulticast
flag on or off the driver checks whether any VLANs are configured
over the interface (except default VLAN 0).
If any extra VLANs are registered it enables multicast promiscuous
mode for all these VLANs (including default VLAN 0) using
ICE_SW_LKUP_PROMISC_VLAN look-up type. In this situation all
multicast packets tagged with known VLAN ID or untagged are received
and multicast packets tagged with unknown VLAN ID ignored.
If no extra VLANs are registered (so only VLAN 0 exists) it enables
multicast promiscuous mode for VLAN 0 and uses ICE_SW_LKUP_PROMISC
look-up type. In this situation any multicast packets including
tagged ones are received.
The driver handles IFF_ALLMULTI in ice_vsi_sync_fltr() this way:
ice_vsi_sync_fltr() {
...
if (changed_flags & IFF_ALLMULTI) {
if (netdev->flags & IFF_ALLMULTI) {
if (vsi->num_vlans > 1)
ice_set_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS);
else
ice_set_promisc(..., ICE_MCAST_PROMISC_BITS);
} else {
if (vsi->num_vlans > 1)
ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS);
else
ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS);
}
}
...
}
The code above depends on value vsi->num_vlan that specifies number
of VLANs configured over the interface (including VLAN 0) and
this is problem because that value is modified in NDO callbacks
ice_vlan_rx_add_vid() and ice_vlan_rx_kill_vid().
Scenario 1:
1. ip link set ens7f0 allmulticast on
2. ip link add vlan10 link ens7f0 type vlan id 10
3. ip link set ens7f0 allmulticast off
4. ip link set ens7f0 allmulticast on
[1] In this scenario IFF_ALLMULTI is enabled and the driver calls
ice_set_promisc(..., ICE_MCAST_PROMISC_BITS) that installs
multicast promisc rule with non-VLAN look-up type.
[2] Then VLAN with ID 10 is added and vsi->num_vlan incremented to 2
[3] Command switches IFF_ALLMULTI off and the driver calls
ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS) but this
call is effectively NOP because it looks for multicast promisc
rules for VLAN 0 and VLAN 10 with VLAN look-up type but no such
rules exist. So the all-multicast remains enabled silently
in hardware.
[4] Command tries to switch IFF_ALLMULTI on and the driver calls
ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS) but this call
fails (-EEXIST) because non-VLAN multicast promisc rule already
exists.
Scenario 2:
1. ip link add vlan10 link ens7f0 type vlan id 10
2. ip link set ens7f0 allmulticast on
3. ip link add vlan20 link ens7f0 type vlan id 20
4. ip link del vlan10 ; ip link del vlan20
5. ip link set ens7f0 allmulticast off
[1] VLAN with ID 10 is added and vsi->num_vlan==2
[2] Command switches IFF_ALLMULTI on and driver installs multicast
promisc rules with VLAN look-up type for VLAN 0 and 10
[3] VLAN with ID 20 is added and vsi->num_vlan==3 but no multicast
promisc rules is added for this new VLAN so the interface does
not receive MC packets from VLAN 20
[4] Both VLANs are removed but multicast rule for VLAN 10 remains
installed so interface receives multicast packets from VLAN 10
[5] Command switches IFF_ALLMULTI off and because vsi->num_vlan is 1
the driver tries to remove multicast promisc rule for VLAN 0
with non-VLAN look-up that does not exist.
All-multicast looks disabled from user point of view but it
is partially enabled in HW (interface receives all multicast
packets either untagged or tagged with VLAN ID 10)
To resolve these issues the patch introduces these changes:
1. Adds handling for IFF_ALLMULTI to ice_vlan_rx_add_vid() and
ice_vlan_rx_kill_vid() callbacks. So when VLAN is added/removed
and IFF_ALLMULTI is enabled an appropriate multicast promisc
rule for that VLAN ID is added/removed.
2. In ice_vlan_rx_add_vid() when first VLAN besides VLAN 0 is added
so (vsi->num_vlan == 2) and IFF_ALLMULTI is enabled then look-up
type for existing multicast promisc rule for VLAN 0 is updated
to ICE_MCAST_VLAN_PROMISC_BITS.
3. In ice_vlan_rx_kill_vid() when last VLAN besides VLAN 0 is removed
so (vsi->num_vlan == 1) and IFF_ALLMULTI is enabled then look-up
type for existing multicast promisc rule for VLAN 0 is updated
to ICE_MCAST_PROMISC_BITS.
4. Both ice_vlan_rx_{add,kill}_vid() have to run under ICE_CFG_BUSY
bit protection to avoid races with ice_vsi_sync_fltr() that runs
in ice_service_task() context.
5. Bit ICE_VSI_VLAN_FLTR_CHANGED is use-less and can be removed.
6. Error messages added to ice_fltr_*_vsi_promisc() helper functions
to avoid them in their callers
7. Small improvements to increase readability

Commit 2ccc1c1ccc671b ("ice: Remove excess error variables") merged
the usage of 'status' and 'err' variables into single one in
function ice_set_mac_address(). Unfortunately this causes
a regression when call of ice_fltr_add_mac() returns -EEXIST because
this return value does not indicate an error in this case but
value of 'err' remains to be -EEXIST till the end of the function
and is returned to caller.
Prior mentioned commit this does not happen because return value of
ice_fltr_add_mac() was stored to 'status' variable first and
if it was -EEXIST then 'err' remains to be zero.
Fix the problem by reset 'err' to zero when ice_fltr_add_mac()
returns -EEXIST.

VSI is set as default forwarding one when promisc mode is set for
PF interface, when PF is switched to switchdev mode or when VF
driver asks to enable allmulticast or promisc mode for the VF
interface (when vf-true-promisc-support priv flag is off).
The third case is buggy because in that case VSI associated with
VF remains as default one after VF removal.
Reproducer:
1. Create VF
echo 1 > sys/class/net/ens7f0/device/sriov_numvfs
2. Enable allmulticast or promisc mode on VF
ip link set ens7f0v0 allmulticast on
ip link set ens7f0v0 promisc on
3. Delete VF
echo 0 > sys/class/net/ens7f0/device/sriov_numvfs
4. Try to enable promisc mode on PF
ip link set ens7f0 promisc on
Although it looks that promisc mode on PF is enabled the opposite
is true because ice_vsi_sync_fltr() responsible for IFF_PROMISC
handling first checks if any other VSI is set as default forwarding
one and if so the function does not do anything. At this point
it is not possible to enable promisc mode on PF without re-probe
device.
To resolve the issue this patch clear default forwarding VSI
during ice_vsi_release() when the VSI to be released is the default
one.

in commit 048939088220
("vrf: add mac header for tunneled packets when sniffer is attached")
an Ethernet header was cooked for traffic originating from tunnel devices.
However, the header is added based on whether the mac_header is unset
and ignores cases where the device doesn't expose a mac header to upper
layers, such as in ip tunnels like ipip and gre.
Traffic originating from such devices still appears garbled when capturing
on the vrf device.
Fix by observing whether the original device exposes a header to upper
layers, similar to the logic done in af_packet.
In addition, skb->mac_len needs to be adjusted after adding the Ethernet
header for the skb_push/pull() surrounding dev_queue_xmit_nit() to work
on these packets.

After rx/tx ring buffer size is changed, kernel panic occurs when
it acts XDP_TX or XDP_REDIRECT.
When tx/rx ring buffer size is changed(ethtool -G), sfc driver
reallocates and reinitializes rx and tx queues and their buffer
(tx_queue->buffer).
But it misses reinitializing xdp queues(efx->xdp_tx_queues).
So, while it is acting XDP_TX or XDP_REDIRECT, it uses the uninitialized
tx_queue->buffer.
A new function efx_set_xdp_channels() is separated from efx_set_channels()
to handle only xdp queues.
Splat looks like:

Marc Kleine-Budde says:
====================
pull-request: can 2022-03-31
The first patch is by Oliver Hartkopp and fixes MSG_PEEK feature in
the CAN ISOTP protocol (broken in net-next for v5.18 only).
Tom Rix's patch for the mcp251xfd driver fixes the propagation of an
error value in case of an error.
A patch by me for the m_can driver fixes a use-after-free in the xmit
handler for m_can IP cores v3.0.x.
Hangyu Hua contributes 3 patches fixing the same double free in the
error path of the xmit handler in the ems_usb, usb_8dev and mcba_usb
USB CAN driver.
Pavel Skripkin contributes a patch for the mcba_usb driver to properly
check the endpoint type.
The last patch is by me and fixes a mem leak in the gs_usb, which was
introduced in net-next for v5.18.

Currently, the debugfs mechanism is that all functions share a
global variable to save the pointer for obtaining data. When
different functions concurrently access the same file node,
repeated release exceptions occur. Therefore, the granularity
of the pointer for storing the obtained data is adjusted to be
private for each function.

timing configuration
Some CAN-FD capable devices offer extended bit timing information for
the data bit timing. The information must be read with an USB control

The previous commit fixed a memory leak on the send path in the event
that IPv6 is disabled at compile time, but how did a packet even arrive
there to begin with? It turns out we have previously allowed IPv6
endpoints even when IPv6 support is disabled at compile time. This is
awkward and inconsistent. Instead, let's just ignore all things IPv6,
the same way we do other malformed endpoints, in the case where IPv6 is
disabled.

We make too nuanced use of ptr_ring to entirely move to the skb_array
wrappers, but we at least should avoid the naughty function pointer cast
when cleaning up skbs. Otherwise RAP/CFI will honk at us. This patch
uses the __skb_array_destroy_skb wrapper for the cleanup, rather than
directly providing kfree_skb, which is what other drivers in the same
situation do too.

function is also transitioned to use dev_err_probe() to provide better

Pull rpmsg updates from Bjorn Andersson:
"The major part of the rpmsg changes for v5.18 relates to improvements
in the rpmsg char driver, which now allow automatically attaching to
rpmsg channels as well as initiating new communication channels from
the Linux side.
The SMD driver is moved to arch_initcall with the purpose of
registering root clocks earlier during boot.
Also in the SMD driver, a workaround for the resource power management
(RPM) channel is introduced to resolve an issue where both the RPM and
Linux side waits for the other to close the communication established
by the bootloader - this unblocks support for clocks and regulators on
some older Qualcomm platforms"

Pull clk updates from Stephen Boyd:
"There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each
time the rate is changed. Previously we wouldn't let clk providers see
a rate that was different if it was still within the range, which
could be bad for power if the clk could run slower when a range
expands. Now the clk provider can decide to do something differently
when the constraints change. This broke Nvidia's clk driver so we had
to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk
framework that we're going to extend in the next release. It already
made it easy to find corner cases in the rate range patches so I'm
excited to see it cover more clk code and increase our confidence in
core framework patches in the future. I also added a kunit test for
the basic clk gate code and that work will continue to cover more
basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and
additions. Qualcomm again dominates the diffstat here with lots more
SoCs being supported and i.MX follows afer that with a similar number
of SoCs gaining clk drivers. Beyond those large additions there's
drivers being modernized to use clk_parent_data so we can move away
from global string names for all the clks in an SoC. Finally there's
lots of little fixes all over the clk drivers for typos, warnings, and
missing clks that aren't critical and get batched up waiting for the
next merge window to open. Nothing super big stands out in the driver
pile. Full details are below.
Core:
- Make clk_set_rate_range() re-evaluate the limits each time
- Introduce various clk_set_rate_range() tests
- Add clk_drop_range() to drop a previously set range

Add the missing logic to allow Lasi, WAX and Dino to set the
CPU affinity. This fixes IRQ migration to other CPUs when a
CPU is shutdown which currently holds the IRQs for one of those
chips.
