The HiperSockets-based transport path in af_iucv is still too closely
entangled with qeth.
With commit
a647a02512ca ("s390/qeth: speed-up L3 IQD xmit"), the
relevant xmit code in qeth has begun to use skb_cow_head(). So to avoid
unnecessary skb head expansions, af_iucv must learn to
1) respect dev->needed_headroom when allocating skbs, and
2) drop the header reference before cloning the skb.
While at it, also stop hard-coding the LL-header creation stage and just
use the appropriate helper.

net/udp_gso: Allow TX timestamp with UDP GSO
[ Upstream commit
76e21533a48bb42d1fa894f93f6233bf4554f45e ]
Fixes an issue where TX Timestamps are not arriving on the error queue
when UDP_SEGMENT CMSG type is combined with CMSG type SO_TIMESTAMPING.
This can be illustrated with an updated updgso_bench_tx program which
includes the '-T' option to test for this condition. It also introduces
the '-P' option which will call poll() before reading the error queue.
./udpgso_bench_tx -4ucTPv -S 1472 -l2 -D 172.16.120.18
poll timeout
udp tx: 0 MB/s 1 calls/s 1 msg/s
The "poll timeout" message above indicates that TX timestamp never
arrived.
This patch preserves tx_flags for the first UDP GSO segment. Only the
first segment is timestamped, even though in some cases there may be
benefital in timestamping both the first and last segment.
Factors in deciding on first segment timestamp only:
- Timestamping both first and last segmented is not feasible. Hardware
can only have one outstanding TS request at a time.
- Timestamping last segment may under report network latency of the
previous segments. Even though the doorbell is suppressed, the ring
producer counter has been incremented.
- Timestamping the first segment has the upside in that it reports
timestamps from the application's view, e.g. RTT.
- Timestamping the first segment has the downside that it may
underreport tx host network latency. It appears that we have to pick
one or the other. And possibly follow-up with a config flag to choose
behavior.

net: netem: fix backlog accounting for corrupted GSO frames
[ Upstream commit
177b8007463c4f36c9a2c7ce7aa9875a4cad9bd5 ]
When GSO frame has to be corrupted netem uses skb_gso_segment()
to produce the list of frames, and re-enqueues the segments one
by one. The backlog length has to be adjusted to account for
new frames.
The current calculation is incorrect, leading to wrong backlog
lengths in the parent qdisc (both bytes and packets), and
incorrect packet backlog count in netem itself.
Parent backlog goes negative, netem's packet backlog counts
all non-first segments twice (thus remaining non-zero even
after qdisc is emptied).
Move the variables used to count the adjustment into local
scope to make 100% sure they aren't used at any stage in
backports.

The call to sc_buffer_alloc currently returns NULL (no buffer) or

There is a third case when the port is down. Currently that
returns NULL and this prevents the caller from properly handling the
sc_buffer_alloc() failure. A verbs code link test after the call is
racy so the indication needs to come from the state check inside the allocation
routine to be valid.

are added at all call sites. For verbs send, this needs to treat any
error by returning a completion without any MMIO copy.

[ Upstream commit
90d4fa39d028f2e46c57c3d0e1b759e5287d98b7 ]
It is incorrect to specify the no-ether-link property for the AVB device on
the Ebisu board. This is because the property should only be used when a
board does not provide a proper AVB_LINK signal. However, the Ebisu board
does provide this signal.
As per
87c059e9c39d ("arm64: dts: renesas: salvator-x: Remove renesas,
no-ether-link property") this fixes a bug:
Steps to reproduce:
- start AVB TX stream (Using aplay via MSE),
- disconnect+reconnect the eth cable,
- after a reconnection the eth connection goes iteratively up/down
without user interaction,
- this may heal after some seconds or even stay for minutes.
As the documentation specifies, the "renesas,no-ether-link" option
should be used when a board does not provide a proper AVB_LINK signal.
There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS
and ULCB starter kits since the AVB_LINK is correctly handled by HW.
Choosing to keep or remove the "renesas,no-ether-link" option will have
impact on the code flow in the following ways:
- keeping this option enabled may lead to unexpected behavior since the
RX & TX are enabled/disabled directly from adjust_link function
without any HW interrogation,
- removing this option, the RX & TX will only be enabled/disabled after
HW interrogation. The HW check is made through the LMON pin in PSR
register which specifies AVB_LINK signal value (0 - at low level;
1 - at high level).
In conclusion, the present change is also a safety improvement because
it removes the "renesas,no-ether-link" option leading to a proper way
of detecting the link state based on HW interrogation and not on
software heuristic.

The locking in force_sig_info is not prepared to deal with a task that

in force_sig as force_sig is only built to handle synchronous
exceptions.
Further the function force_sig_info changes the signal state if the

delivery of the signal. The signal SIGKILL can not be ignored and can
not be blocked and SIGNAL_UNKILLABLE won't prevent it from being
delivered.
So using force_sig rather than send_sig for SIGKILL is confusing
and pointless.
Because it won't impact the sending of the signal and and because
using force_sig is wrong, replace force_sig with send_sig.

Commit
f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status")
added support to save and restore the DMA channel registers when runtime
suspending the ADMA. This change is causing the kernel to crash when
probing the ADMA, if the device is probed deferred when looking up the
channel interrupts. The crash occurs because not all of the channel base
addresses have been setup at this point and in the clean-up path of the
probe, pm_runtime_suspend() is called invoking its callback which
expects all the channel base addresses to be initialised.
Although this could be fixed by simply checking for a NULL address, on
further review of the driver it seems more appropriate that we only call
pm_runtime_get_sync() after all the channel interrupts and base
addresses have been configured. Therefore, fix this crash by moving the
calls to pm_runtime_enable(), pm_runtime_get_sync() and
tegra_adma_init() after the DMA channels have been initialised.

There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

nfp: bpf: fix static check error through tightening shift amount adjustment
[ Upstream commit
69e168ebdcfcb87ce7252d4857d570f99996fa27 ]
NFP shift instruction has something special. If shift direction is left
then shift amount of 1 to 31 is specified as 32 minus the amount to shift.
But no need to do this for indirect shift which has shift amount be 0. Even
after we do this subtraction, shift amount 0 will be turned into 32 which
will eventually be encoded the same as 0 because only low 5 bits are
encoded, but shift amount be 32 will fail the FIELD_PREP check done later
on shift mask (0x1f), due to 32 is out of mask range. Such error has been
observed when compiling nfp/bpf/jit.c using gcc 8.3 + O3.
This issue has started when indirect shift support added after which the
incoming shift amount to __emit_shf could be 0, therefore it is at that
time shift amount adjustment inside __emit_shf should have been tightened.

51496e4446875726d50a5617a6e0e0dabbc2e6da ]
The pre-divider allows configuring longer PWM periods compared to using
the input clock directly. The pre-divider is 7 bit wide, meaning it's
maximum value is 128 (the register value is off-by-one: 0x7f or 127).
Change the loop to also allow for the maximum possible value to be
considered valid.

to use the value that gets written to it when we call videobuf_dqbuf().
The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function. It's this final value which we
want.
Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf(). I ended up doing a little cleanup related to that as

vfio/mdev: Fix aborting mdev child device removal if one fails
[ Upstream commit
6093e348a5e2475c5bb2e571346460f939998670 ]
device_for_each_child() stops executing callback function for remaining
child devices, if callback hits an error.
Each child mdev device is independent of each other.
While unregistering parent device, mdev core must remove all child mdev
devices.
Therefore, mdev_device_remove_cb() always returns success so that
device_for_each_child doesn't abort if one child removal hits error.
While at it, improve remove and unregister functions for below simplicity.
There isn't need to pass forced flag pointer during mdev parent
removal which invokes mdev_device_remove(). So simplify the flow.
mdev_device_remove() is called from two paths.
1. mdev_unregister_driver()
mdev_device_remove_cb()
mdev_device_remove()
2. remove_store()
mdev_device_remove()

iommu/vt-d: Make kernel parameter igfx_off work with vIOMMU
[ Upstream commit
5daab58043ee2bca861068e2595564828f3bc663 ]
The kernel parameter igfx_off is used by users to disable
DMA remapping for the Intel integrated graphic device. It
was designed for bare metal cases where a dedicated IOMMU
is used for graphic. This doesn't apply to virtual IOMMU
case where an include-all IOMMU is used. This makes the
kernel parameter work with virtual IOMMU as well.

IB/mlx5: Add missing XRC options to QP optional params mask
[ Upstream commit
8f4426aa19fcdb9326ac44154a117b1a3a5ae126 ]
The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.
Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table. These omissions caused failures when doing XRC QP
state transitions.
For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.
Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.

be valid and not have any channel. Let's use this condition instead to

packet: in recvmsg msg_name return at least sizeof sockaddr_ll
[ Upstream commit

Packet send checks that msg_name is at least sizeof sockaddr_ll.
Packet recv must return at least this length, so that its output
can be passed unmodified to packet send.
This ceased to be true since adding support for lladdr longer than
sll_addr. Since, the return value uses true address length.
Always return at least sizeof sockaddr_ll, even if address length
is shorter. Zero the padding bytes.
Change v1->v2: do not overwrite zeroed padding again. use copy_len.
