This reverts commit b3484d2b03e4c940a9598aa841a52d69729c582a.
That change attempted to improve the DRM drivers fbdev emulation device
names to avoid having confusing names like "simpledrmdrmfb" in /proc/fb.
But unfortunately, there are user-space programs such as pm-utils that
match against the fbdev names and so broke after the mentioned commit.
Since the names in /proc/fb are used by tools that consider it an uAPI,
let's restore the old names even when this lead to silly names like the
one mentioned above.

The driver currently assumes that the notify callback is only received
when the device is done with all the queued buffers.
However, this is not true, since the notify callback could be called
without any of the queued buffers being completed (for example, with
virtio-pci and shared interrupts) or with only some of the buffers being
completed (since the driver makes them available to the device in
multiple separate virtqueue_add_sgs() calls).
This can lead to incorrect data on the I2C bus or memory corruption in
the guest if the device operates on buffers which are have been freed by
the driver. (The WARN_ON in the driver is also triggered.)

The CAN clock frequency is used when calculating the CAN bittiming
parameters. When wrong clock frequency is used, the device may end up
with wrong bittiming parameters, depending on user requested bittiming
parameters.
To avoid this, get the CAN clock frequency from the device. Various
existing Kvaser Leaf products use different CAN clocks.

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.
[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.
Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.

The registration of XDP queue information is incorrect because the
RX queue id we use is invalid. When port->id == 0 it appears to works
as expected yet it's no longer the case when port->id != 0.
The problem arised while using a recent kernel version on the
MACCHIATOBin. This board has several ports:
* eth0 and eth1 are 10Gbps interfaces ; both ports has port->id == 0;
* eth2 is a 1Gbps interface with port->id != 0.
Code from xdp-tutorial (more specifically advanced03-AF_XDP) was used
to test packet capture and injection on all these interfaces. The XDP
kernel was simplified to:
SEC("xdp_sock")
int xdp_sock_prog(struct xdp_md *ctx)
{
int index = ctx->rx_queue_index;
/* A set entry here means that the correspnding queue_id
* has an active AF_XDP socket bound to it. */
if (bpf_map_lookup_elem(&xsks_map, &index))
return bpf_redirect_map(&xsks_map, index, 0);
return XDP_PASS;
}
Starting the program using:
./af_xdp_user -d DEV
Gives the following result:
* eth0 : ok
* eth1 : ok
* eth2 : no capture, no injection
Investigating the issue shows that XDP rx queues for eth2 are wrong:
XDP expects their id to be in the range [0..3] but we found them to be
in the range [32..35].
Trying to force rx queue ids using:
./af_xdp_user -d eth2 -Q 32
fails as expected (we shall not have more than 4 queues).
When we register the XDP rx queue information (using
xdp_rxq_info_reg() in function mvpp2_rxq_init()) we tell it to use
rxq->id as the queue id. This value is computed as:
rxq->id = port->id * max_rxq_count + queue_id
where max_rxq_count depends on the device version. In the MACCHIATOBin
case, this value is 32, meaning that rx queues on eth2 are numbered
from 32 to 35 - there are four of them.
Clearly, this is not the per-port queue id that XDP is expecting:
it wants a value in the range [0..3]. It shall directly use queue_id
which is stored in rxq->logic_rxq -- so let's use that value instead.
rxq->id is left untouched ; its value is indeed valid but it should
not be used in this context.
This is consistent with the remaining part of the code in
mvpp2_rxq_init().
With this change, packet capture is working as expected on all the
MACCHIATOBin ports.

This commit fixes a misunderstanding in commit 4a3e0aeddf09 ("net: dsa:
mv88e6xxx: don't use PHY_DETECT on internal PHY's").
For Marvell DSA switches with the PHY_DETECT bit (for non-6250 family
devices), controls whether the PPU polls the PHY to retrieve the link,
speed, duplex and pause status to update the port configuration. This
applies for both internal and external PHYs.
For some switches such as 88E6352 and 88E6390X, PHY_DETECT has an
additional function of enabling auto-media mode between the internal
PHY and SERDES blocks depending on which first gains link.
The original intention of commit 5d5b231da7ac (net: dsa: mv88e6xxx: use
PHY_DETECT in mac_link_up/mac_link_down) was to allow this bit to be
used to detect when this propagation is enabled, and allow software to
update the port configuration. This has found to be necessary for some
switches which do not automatically propagate status from the SERDES to
the port, which includes the 88E6390. However, commit 4a3e0aeddf09
("net: dsa: mv88e6xxx: don't use PHY_DETECT on internal PHY's") breaks
this assumption.
Maarten Zanders has confirmed that the issue he was addressing was for
an 88E6250 switch, which does not have a PHY_DETECT bit in bit 12, but
instead a link status bit. Therefore, mv88e6xxx_port_ppu_updates() does
not report correctly.
This patch resolves the above issues by reverting Maarten's change and
instead making mv88e6xxx_port_ppu_updates() indicate whether the port
is internal for the 88E6250 family of switches.
Yes, you're right, I'm targeting the 6250 family. And yes, your
suggestion would solve my case and is a better implementation for
the other devices (as far as I can see).

virtio_max_dma_size() returns the maximum DMA mapping size of the virtio
device by querying dma_max_mapping_size() for the device when the DMA
API is in use for the vring. Unfortunately, the device passed is
initialised by register_virtio_device() and does not inherit the DMA
configuration from its parent, resulting in SWIOTLB errors when bouncing
is enabled and the default 256K mapping limit (IO_TLB_SEGSIZE) is not
respected:
| virtio-pci 0000:00:01.0: swiotlb buffer is full (sz: 294912 bytes), total 1024 (slots), used 725 (slots)
Follow the pattern used elsewhere in the virtio_ring code when calling
into the DMA layer and pass the parent device to dma_max_mapping_size()
instead.

This condition checks "len" but it does not check "offset" and that
could result in an out of bounds read if "offset > dev->config_size".
The problem is that since both variables are unsigned the
"dev->config_size - offset" subtraction would result in a very high
unsigned value.
I think these checks might not be necessary because "len" and "offset"
are supposed to already have been validated using the
vhost_vdpa_config_validate() function. But I do not know the code
perfectly, and I like to be safe.

In this function "c->off" is a u32 and "size" is a long. On 64bit systems
if "c->off" is greater than "size" then "size - c->off" is a negative and

promoted to a high positive u32 value and basically any "c->len" is

The "config.offset" comes from the user. There needs to a check to
prevent it being out of bounds. The "config.offset" and
"dev->config_size" variables are both type u32. So if the offset if
out of bounds then the "dev->config_size - config.offset" subtraction
results in a very high u32 value. The out of bounds offset can result
in memory corruption.

The driver was zeroing live stats that could be fetched by
ndo_get_stats64 at any time. This could result in inconsistent
statistics, and the telltale sign was when reading stats frequently from
/proc/net/dev, the stats would go backwards.
Fix by collecting stats into a local, and delaying when we write to the
structure so it's not incremental.

This is now the only driver that selects the LEDS_CLASS framework,
which is normally user-selectable. While it doesn't strictly cause
a bug, rework the Kconfig logic to be more consistent with what
other drivers do, and only enable LED support in brcmsmac if the
dependencies are all there, rather than using 'select' to enable
what it needs.

The dependencies for LED configuration are highly inconsistent and too
complicated at the moment. One of the results is a randconfig failure I
get very rarely when LEDS_CLASS is in a loadable module, but the wireless
core is built-in:
WARNING: unmet direct dependencies detected for MAC80211_LEDS

led.c:(.text+0x200): undefined reference to `led_classdev_unregister'
For iwlwifi, the dependency is wrong, since this config prevents the
MAC80211_LEDS code from being part of a built-in MAC80211 driver.
For iwlegacy, this is worse because the driver tries to force-enable
the other subsystems, which is both a layering violation and a bug
because it will still fail with MAC80211=y and IWLEGACY=m, leading
to LEDS_CLASS being a module as well.
The actual link failure in the ath5k driver is a result of MAC80211_LEDS
being enabled but not usable. With the Kconfig logic fixed in the
Intel drivers, the ath5k driver works as expected again.

dma_fence_chain_find_seqno only ever returns the top fence in the
chain or an unsignalled fence. Hence if we request a seqno that
is already signalled it returns a NULL fence. Some callers are
not prepared to handle this, like the syncobj transfer functions
for example.
This behavior is "new" with timeline syncobj and it looks like
not all callers were updated. To fix this behavior make sure
that a successful drm_sync_find_fence always returns a non-NULL
fence.

functions.

At the moment, using the ARM32 multi_v7_defconfig always results in two
SoCs being exposed in sysfs. This is wrong, as far as I'm aware the
Qualcomm DragonBoard 410c does not actually make use of a i.MX SoC. :)
qcom-db410c:/sys/devices/soc0$ grep . *
family:Freescale i.MX
machine:Qualcomm Technologies, Inc. APQ 8016 SBC
revision:0.0
serial_number:0000000000000000
soc_id:Unknown
qcom-db410c:/sys/devices/soc1$ grep . *
family:Snapdragon
machine:APQ8016
...
This happens because imx_soc_device_init() registers the soc device
unconditionally, even when running on devices that do not make use of i.MX.
Arnd already reported this more than a year ago and even suggested a fix
similar to this commit, but for some reason it was never submitted.
Fix it by checking if the "__mxc_cpu_type" variable was actually
initialized by earlier platform code. On devices without i.MX it will
simply stay 0.

Background:
We have a customer is running a Profinet stack on the 8MM which receives and
responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from
time to time the received PNIO-CM package is "stock" and is only handled when
receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and
the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from
the expected 40 ms and not the 2s delay of the DCERPC-Ping).
After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would
be handled by different RX queues.
The root cause should be driver ack all queues' interrupt when handle a
specific queue in fec_enet_rx_queue(). The blamed patch is introduced to
receive as much packets as possible once to avoid interrupt flooding.
But it's unreasonable to clear other queues'interrupt when handling one
queue, this patch tries to fix it.

Before commit fc0c209c147f ("clk: Allow parents to be specified without
string names") child clks couldn't find their parent until the parent
clk was added to a list in __clk_core_init(). After that commit, child
clks can reference their parent clks directly via a clk_hw pointer, or
they can lookup that clk_hw pointer via DT if the parent clk is
registered with an OF clk provider.
The common clk framework treats hw->core being non-NULL as "the clk is
registered" per the logic within clk_core_fill_parent_index():
parent = entry->hw->core;
/*
* We have a direct reference but it isn't registered yet?
* Orphan it and let clk_reparent() update the orphan status
* when the parent is registered.
*/
if (!parent)
Therefore we need to be extra careful to not set hw->core until the clk
is fully registered with the clk framework. Otherwise we can get into a
situation where a child finds a parent clk and we move the child clk off
the orphan list when the parent isn't actually registered, wrecking our
enable accounting and breaking critical clks.
Consider the following scenario:
CPU0 CPU1
---- ----
struct clk_hw clkBad;
struct clk_hw clkA;
clkA.init.parent_hws = { &clkBad };
clk_hw_register(&clkA) clk_hw_register(&clkBad)
... __clk_register()
hw->core = core
...
__clk_register()
__clk_core_init()
clk_prepare_lock()
__clk_init_parent()
clk_core_get_parent_by_index()
clk_core_fill_parent_index()
if (entry->hw) {
parent = entry->hw->core;
At this point, 'parent' points to clkBad even though clkBad hasn't been
fully registered yet. Ouch! A similar problem can happen if a clk
controller registers orphan clks that are referenced in the DT node of
another clk controller.
Let's fix all this by only setting the hw->core pointer underneath the
clk prepare lock in __clk_core_init(). This way we know that
clk_core_fill_parent_index() can't see hw->core be non-NULL until the
clk is fully registered.

After the below patch, the conntrack attached to skb is set to "notrack" in
the context of vrf device, for locally generated packets.
But this is true only when the default qdisc is set to the vrf device. When
changing the qdisc, notrack is not set anymore.
In fact, there is a shortcut in the vrf driver, when the default qdisc is
set, see commit dcdd43c41e60 ("net: vrf: performance improvements for
IPv4") for more details.
This patch ensures that the behavior is always the same, whatever the qdisc
is.
To demonstrate the difference, a new test is added in conntrack_vrf.sh.

In tunnels packet there can be two UDP headers:
- outer which for hw should be mark as ICE_UDP_OF
- inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if
inner header is of TCP type
In none tunnels packet header can be:
- UDP, which for hw should be mark as ICE_UDP_ILOS
- TCP, which for hw should be mark as ICE_TCP_IL
Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS.
ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to
error from hw while adding this kind of recipe.
In summary, for tunnel outer port type should always be set to
ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be
set to ICE_UDP_ILOS.

If the hardware is constantly receiving unicast or broadcast packets
during driver load, the device previously counted many GLV_RDPC (VSI
dropped packets) events during init. This causes confusing dropped
packet statistics during driver load. The dropped packets counter
incrementing does stop once the driver finishes loading.
Avoid this problem by baselining our statistics at the end of driver
open instead of the end of probe.

The same patch also added a check for when the DCBx state could

This frees "name" and then tries to display in as part of the error
message on the next line. Swap the order.

The ql_wait_for_drvr_lock() fails and returns false, then this
function should return an error code instead of returning success.
The other problem is that the success path prints an error message
netdev_err(ndev, "Releasing driver lock\n"); Delete that and
re-order the code a little to make it more clear.
