[ Upstream commit 0cff90dec6 ]
The arguments for __dma_buf_debugfs_list_del do not match for both the
CONFIG_DEBUG_FS case and the !CONFIG_DEBUG_FS case. The !CONFIG_DEBUG_FS
case should take a struct dma_buf *, but it's currently struct file *.
This can lead to the build error:
error: passing argument 1 of ‘__dma_buf_debugfs_list_del’ from
incompatible pointer type [-Werror=incompatible-pointer-types]

[ Upstream commit f49856f525 ]
In export_udmabuf(), if dma_buf_fd() fails because the FD table is full, a
dma_buf owning the udmabuf has already been created; but the error handling
in udmabuf_create() will tear down the udmabuf without doing anything about
the containing dma_buf.
This leaves a dma_buf in memory that contains a dangling pointer; though
that doesn't seem to lead to anything bad except a memory leak.
Fix it by moving the dma_buf_fd() call out of export_udmabuf() so that we
can give it different error handling.
Note that the shape of this code changed a lot in commit 5e72b2b41a
("udmabuf: convert udmabuf driver to use folios"); but the memory leak
seems to have existed since the introduction of udmabuf.

commit 24740385cb upstream.
When USB-C monitor is connected directly to Intel Barlow Ridge host, it
goes into "redrive" mode that basically routes the DisplayPort signals
directly from the GPU to the USB-C monitor without any tunneling needed.
However, the host router must be powered on for this to work. Aaron
reported that there are a couple of cases where this will not work with
the current code:
- Booting with USB-C monitor plugged in.
- Plugging in USB-C monitor when the host router is in sleep state
(runtime suspended).
- Plugging in USB-C device while the system is in system sleep state.
In all these cases once the host router is runtime suspended the picture
on the connected USB-C display disappears too. This is certainly not
what the user expected.
For this reason improve the redrive mode handling to keep the host
router from runtime suspending when detect that any of the above cases
is happening.

When looking up a non-existent file, efivarfs returns -EINVAL if the

This is caused by efivars_d_hash() returning -EINVAL if the name is not

returns a negative dentry, and is the error value that the user sees.
Fix by removing this check. If the file does not exist, simple_lookup()
will return a negative dentry leading to -ENOENT and efivarfs_create()
already has a validity check before it creates an entry (and will
correctly return -EINVAL)

commit de6b43798d upstream.
Currently, the RIIC driver may run the I2C bus faster than requested,
which may cause subtle failures. E.g. Biju reported a measured bus
speed of 450 kHz instead of the expected maximum of 400 kHz on RZ/G2L.
The initial calculation of the bus period uses DIV_ROUND_UP(), to make
sure the actual bus speed never becomes faster than the requested bus
speed. However, the subsequent division-by-two steps do not use
round-up, which may lead to a too-small period, hence a too-fast and
possible out-of-spec bus speed. E.g. on RZ/Five, requesting a bus speed
of 100 resp. 400 kHz will yield too-fast target bus speeds of 100806
resp. 403226 Hz instead of 97656 resp. 390625 Hz.
Fix this by using DIV_ROUND_UP() in the subsequent divisions, too.
Tested on RZ/A1H, RZ/A2M, and RZ/Five.

means we may leak skbs if a message is not successfully queued to a

Instead, ensure that we're freeing the skb where the sock hasn't
otherwise taken ownership of the skb by adding checks on the
sock_queue_rcv_skb() to invoke a kfree on failure.
In doing so, rather than using the 'rc' value to trigger the
kfree_skb(), use the skb pointer itself, which is more explicit.
Also, add a kunit test for the sock delivery failure cases.

commit 1201f226c8 upstream.
Snapshot the output of CPUID.0xD.[1..n] during kvm.ko initiliaization to
avoid the overead of CPUID during runtime. The offset, size, and metadata
for CPUID.0xD.[1..n] sub-leaves does not depend on XCR0 or XSS values, i.e.
is constant for a given CPU, and thus can be cached during module load.
On Intel's Emerald Rapids, CPUID is *wildly* expensive, to the point where
recomputing XSAVE offsets and sizes results in a 4x increase in latency of
nested VM-Enter and VM-Exit (nested transitions can trigger
xstate_required_size() multiple times per transition), relative to using
cached values. The issue is easily visible by running `perf top` while
triggering nested transitions: kvm_update_cpuid_runtime() shows up at a
whopping 50%.
As measured via RDTSC from L2 (using KVM-Unit-Test's CPUID VM-Exit test
and a slightly modified L1 KVM to handle CPUID in the fastpath), a nested
roundtrip to emulate CPUID on Skylake (SKX), Icelake (ICX), and Emerald
Rapids (EMR) takes:
SKX 11650
ICX 22350
EMR 28850
Using cached values, the latency drops to:
SKX 6850
ICX 9000
EMR 7900
The underlying issue is that CPUID itself is slow on ICX, and comically
slow on EMR. The problem is exacerbated on CPUs which support XSAVES
and/or XSAVEC, as KVM invokes xstate_required_size() twice on each
runtime CPUID update, and because there are more supported XSAVE features
(CPUID for supported XSAVE feature sub-leafs is significantly slower).
SKX:
CPUID.0xD.2 = 348 cycles
CPUID.0xD.3 = 400 cycles
CPUID.0xD.4 = 276 cycles
CPUID.0xD.5 = 236 cycles
<other sub-leaves are similar>
EMR:
CPUID.0xD.2 = 1138 cycles
CPUID.0xD.3 = 1362 cycles
CPUID.0xD.4 = 1068 cycles
CPUID.0xD.5 = 910 cycles
CPUID.0xD.6 = 914 cycles
CPUID.0xD.7 = 1350 cycles
CPUID.0xD.8 = 734 cycles
CPUID.0xD.9 = 766 cycles
CPUID.0xD.10 = 732 cycles
CPUID.0xD.11 = 718 cycles
CPUID.0xD.12 = 734 cycles
CPUID.0xD.13 = 1700 cycles
CPUID.0xD.14 = 1126 cycles
CPUID.0xD.15 = 898 cycles
CPUID.0xD.16 = 716 cycles
CPUID.0xD.17 = 748 cycles
CPUID.0xD.18 = 776 cycles
Note, updating runtime CPUID information multiple times per nested
transition is itself a flaw, especially since CPUID is a mandotory
intercept on both Intel and AMD. E.g. KVM doesn't need to ensure emulated
CPUID state is up-to-date while running L2. That flaw will be fixed in a
future patch, as deferring runtime CPUID updates is more subtle than it
appears at first glance, the benefits aren't super critical to have once
the XSAVE issue is resolved, and caching CPUID output is desirable even if
KVM's updates are deferred.

commit 03c7527e97 upstream.
Catalin reports that a hypervisor lying to a guest about the size
of the ASID field may result in unexpected issues:
- if the underlying HW does only supports 8 bit ASIDs, the ASID
field in a TLBI VAE1* operation is only 8 bits, and the HW will
ignore the other 8 bits
- if on the contrary the HW is 16 bit capable, the ASID field
in the same TLBI operation is always 16 bits, irrespective of
the value of TCR_ELx.AS.
This could lead to missed invalidations if the guest was lead to
assume that the HW had 8 bit ASIDs while they really are 16 bit wide.
In order to avoid any potential disaster that would be hard to debug,
prenent the migration between a host with 8 bit ASIDs to one with
wider ASIDs (the converse was obviously always forbidden). This is
also consistent with what we already do for VMIDs.
If it becomes absolutely mandatory to support such a migration path
in the future, we will have to trap and emulate all TLBIs, something
that nobody should look forward to.

commit 773c05f417 upstream.
It appears that the relatively popular RK3399 SoC has been put together
using a large amount of illicit substances, as experiments reveal that its
integration of GIC500 exposes the *secure* programming interface to
non-secure.
This has some pretty bad effects on the way priorities are handled, and
results in a dead machine if booting with pseudo-NMI enabled
(irqchip.gicv3_pseudo_nmi=1) if the kernel contains 18fdb6348c ("arm64:
irqchip/gic-v3: Select priorities at boot time"), which relies on the
priorities being programmed using the NS view.
Let's restore some sanity by going one step further and disable security
altogether in this case. This is not any worse, and puts us in a mode where
priorities actually make some sense.
Huge thanks to Mark Kettenis who initially identified this issue on
OpenBSD, and to Chen-Yu Tsai who reported the problem in Linux.

VLAN-unaware bridge ports is broken with ocelot-8021q. He is describing
the same symptoms as for commit 1f9fc48fd3 ("net: dsa: sja1105: fix
reception from VLAN-unaware bridges").
For context, the set merged as "VLAN fixes for Ocelot driver":
https://lore.kernel.org/netdev/20240815000707.2006121-1-vladimir.oltean@nxp.com/
was developed in a slightly different form earlier this year, in January.
Initially, the switch was unconditionally configured to set OCELOT_ES0_TAG
when using ocelot-8021q, regardless of port operating mode.
This led to the situation where VLAN-unaware bridge ports would always
push their PVID - see ocelot_vlan_unaware_pvid() - a negligible value
anyway - into RX packets. To strip this in software, we would have needed
DSA to know what private VID the switch chose for VLAN-unaware bridge
ports, and pushed into the packets. This was implemented downstream, and
a remnant of it remains in the form of a comment mentioning
ds->ops->get_private_vid(), as something which would maybe need to be
considered in the future.
However, for upstream, it was deemed inappropriate, because it would
mean introducing yet another behavior for stripping VLAN tags from
VLAN-unaware bridge ports, when one already existed (ds->untag_bridge_pvid).
The latter has been marked as obsolete along with an explanation why it
is logically broken, but still, it would have been confusing.
So, for upstream, felix_update_tag_8021q_rx_rule() was developed, which
essentially changed the state of affairs from "Felix with ocelot-8021q
delivers all packets as VLAN-tagged towards the CPU" into "Felix with
ocelot-8021q delivers all packets from VLAN-aware bridge ports towards
the CPU". This was done on the premise that in VLAN-unaware mode,
there's nothing useful in the VLAN tags, and we can avoid introducing
ds->ops->get_private_vid() in the DSA receive path if we configure the
switch to not push those VLAN tags into packets in the first place.
Unfortunately, and this is when the trainwreck started, the selftests
developed initially and posted with the series were not re-ran.
dsa_software_vlan_untag() was initially written given the assumption
that users of this feature would send _all_ traffic as VLAN-tagged.
It was only partially adapted to the new scheme, by removing
ds->ops->get_private_vid(), which also used to be necessary in
standalone ports mode.
Where the trainwreck became even worse is that I had a second opportunity
to think about this, when the dsa_software_vlan_untag() logic change
initially broke sja1105, in commit 1f9fc48fd3 ("net: dsa: sja1105: fix
reception from VLAN-unaware bridges"). I did not connect the dots that
it also breaks ocelot-8021q, for pretty much the same reason that not
all received packets will be VLAN-tagged.
To be compatible with the optimized Felix control path which runs
felix_update_tag_8021q_rx_rule() to only push VLAN tags when useful (in
VLAN-aware mode), we need to restore the old dsa_software_vlan_untag()
logic. The blamed commit introduced the assumption that
dsa_software_vlan_untag() will see only VLAN-tagged packets, assumption
which is false. What corrupts RX traffic is the fact that we call
skb_vlan_untag() on packets which are not VLAN-tagged in the first
place.

Fix the way tcpdump is executed by:
- Using the right variable for the namespace. Currently the use of the
empty "ns" makes the command fail.
- Waiting until it starts to capture to ensure the interesting traffic
is caught on slow systems.
- Using line-buffered output to ensure logs are available when the test
is paused with "-p". Otherwise the last chunk of data might only be
written when tcpdump is killed.

[ Upstream commit 70b6f46a4e ]
With CONFIG_PROVE_LOCKING, when creating a set of type bitmap:ip, adding
it to a set of type list:set and populating it from iptables SET target
triggers a kernel warning:

This is a false alarm: ipset does not allow nested list:set type, so the

other set type supports embedded sets, so this is the only case to
consider.
To avoid the false report, create a distinct lock class for list:set

[ Upstream commit cf2c97423a ]
The 'max_avail' value is calculated from the system memory
size using order_base_2().
order_base_2(x) is defined as '(x) ? fn(x) : 0'.
The compiler generates two copies of the code that follows
and then expands clamp(max, min, PAGE_SHIFT - 12) (11 on 32bit).
This triggers a compile-time assert since min is 5.
In reality a system would have to have less than 512MB memory
for the bounds passed to clamp to be reversed.
Swap the order of the arguments to clamp() to avoid the warning.
Replace the clamp_val() on the line below with clamp().
clamp_val() is just 'an accident waiting to happen' and not needed here.
Detected by compile time checks added to clamp(), specifically:

[ Upstream commit 743375f8de ]
The interrupt line of PCI devices is interpreted as edge-triggered,
however the interrupt signal of the m_can controller integrated in Intel
Elkhart Lake CPUs appears to be generated level-triggered.
Consider the following sequence of events:
- IR register is read, interrupt X is set
- A new interrupt Y is triggered in the m_can controller
- IR register is written to acknowledge interrupt X. Y remains set in IR
As at no point in this sequence no interrupt flag is set in IR, the
m_can interrupt line will never become deasserted, and no edge will ever
be observed to trigger another run of the ISR. This was observed to
result in the TX queue of the EHL m_can to get stuck under high load,
because frames were queued to the hardware in m_can_start_xmit(), but
m_can_finish_tx() was never run to account for their successful
transmission.
On an Elkhart Lake based board with the two CAN interfaces connected to
each other, the following script can reproduce the issue:
ip link set can0 up type can bitrate 1000000
ip link set can1 up type can bitrate 1000000
cangen can0 -g 2 -I 000 -L 8 &
cangen can0 -g 2 -I 001 -L 8 &
cangen can0 -g 2 -I 002 -L 8 &
cangen can0 -g 2 -I 003 -L 8 &
cangen can0 -g 2 -I 004 -L 8 &
cangen can0 -g 2 -I 005 -L 8 &

cangen can0 -g 2 -I 007 -L 8 &
cangen can1 -g 2 -I 100 -L 8 &

cangen can1 -g 2 -I 105 -L 8 &
cangen can1 -g 2 -I 106 -L 8 &
cangen can1 -g 2 -I 107 -L 8 &
stress-ng --matrix 0 &
To fix the issue, repeatedly read and acknowledge interrupts at the
start of the ISR until no interrupt flags are set, so the next incoming
interrupt will also result in an edge on the interrupt line.
While we have received a report that even with this patch, the TX queue
can become stuck under certain (currently unknown) circumstances on the
Elkhart Lake, this patch completely fixes the issue with the above
reproducer, and it is unclear whether the remaining issue has a similar
cause at all.

While an m_can controller usually already has the init flag from a
hardware reset, no such reset happens on the integrated m_can_pci of the
Intel Elkhart Lake. If the CAN controller is found in an active state,
m_can_dev_setup() would fail because m_can_niso_supported() calls
m_can_cccr_update_bits(), which refuses to modify any other configuration
bits when CCCR_INIT is not set.
To avoid this issue, set CCCR_INIT before attempting to modify any other
configuration flags.

[ Upstream commit e592b5110b ]
There are two skb pointers to manage tx skb's enqueued from n/w stack.
waiting_tx_skb pointer points to the tx skb which needs to be processed
and ongoing_tx_skb pointer points to the tx skb which is being processed.
SPI thread prepares the tx data chunks from the tx skb pointed by the
ongoing_tx_skb pointer. When the tx skb pointed by the ongoing_tx_skb is
processed, the tx skb pointed by the waiting_tx_skb is assigned to
ongoing_tx_skb and the waiting_tx_skb pointer is assigned with NULL.
Whenever there is a new tx skb from n/w stack, it will be assigned to
waiting_tx_skb pointer if it is NULL. Enqueuing and processing of a tx skb
handled in two different threads.
Consider a scenario where the SPI thread processed an ongoing_tx_skb and
it moves next tx skb from waiting_tx_skb pointer to ongoing_tx_skb pointer
without doing any NULL check. At this time, if the waiting_tx_skb pointer
is NULL then ongoing_tx_skb pointer is also assigned with NULL. After
that, if a new tx skb is assigned to waiting_tx_skb pointer by the n/w
stack and there is a chance to overwrite the tx skb pointer with NULL in
the SPI thread. Finally one of the tx skb will be left as unhandled,
resulting packet missing and memory leak.
- Consider the below scenario where the TXC reported from the previous
transfer is 10 and ongoing_tx_skb holds an tx ethernet frame which can be
transported in 20 TXCs and waiting_tx_skb is still NULL.
tx_credits = 10; /* 21 are filled in the previous transfer */
ongoing_tx_skb = 20;
waiting_tx_skb = NULL; /* Still NULL */
- So, (tc6->ongoing_tx_skb || tc6->waiting_tx_skb) becomes true.
- After oa_tc6_prepare_spi_tx_buf_for_tx_skbs()
ongoing_tx_skb = 10;
waiting_tx_skb = NULL; /* Still NULL */
- Perform SPI transfer.
- Process SPI rx buffer to get the TXC from footers.
- Now let's assume previously filled 21 TXCs are freed so we are good to
transport the next remaining 10 tx chunks from ongoing_tx_skb.
tx_credits = 21;
ongoing_tx_skb = 10;
waiting_tx_skb = NULL;
- So, (tc6->ongoing_tx_skb || tc6->waiting_tx_skb) becomes true again.
- In the oa_tc6_prepare_spi_tx_buf_for_tx_skbs()
ongoing_tx_skb = NULL;
waiting_tx_skb = NULL;
- Now the below bad case might happen,
Thread1 (oa_tc6_start_xmit) Thread2 (oa_tc6_spi_thread_handler)
--------------------------- -----------------------------------
- if waiting_tx_skb is NULL
- if ongoing_tx_skb is NULL
- ongoing_tx_skb = waiting_tx_skb
- waiting_tx_skb = skb
- waiting_tx_skb = NULL
...
- ongoing_tx_skb = NULL
- if waiting_tx_skb is NULL
- waiting_tx_skb = skb
To overcome the above issue, protect the moving of tx skb reference from
waiting_tx_skb pointer to ongoing_tx_skb pointer and assigning new tx skb
to waiting_tx_skb pointer, so that the other thread can't access the
waiting_tx_skb pointer until the current thread completes moving the tx
skb reference safely.

[ Upstream commit 7d2f320e12 ]
SPI thread wakes up to perform SPI transfer whenever there is an TX skb
from n/w stack or interrupt from MAC-PHY. Ethernet frame from TX skb is
transferred based on the availability tx credits in the MAC-PHY which is
reported from the previous SPI transfer. Sometimes there is a possibility
that TX skb is available to transmit but there is no tx credits from
MAC-PHY. In this case, there will not be any SPI transfer but the thread
will be running in an endless loop until tx credits available again.
So checking the availability of tx credits along with TX skb will prevent
the above infinite loop. When the tx credits available again that will be
notified through interrupt which will trigger the SPI transfer to get the
available tx credits.
