[ Upstream commit e9537962519e88969f5f69cd0571eb4f6984403c ]

This reverts commit
443a98e649b4 ("soundwire: bus: use pm_runtime_resume_and_get()")

Change calls to pm_runtime_resume_and_get() back to pm_runtime_get_sync().
This fixes a usage count underrun caused by doing a pm_runtime_put() even
though pm_runtime_resume_and_get() returned an error.

The three affected functions ignore -EACCES error from trying to get
pm_runtime, and carry on, including a put at the end of the function.
But pm_runtime_resume_and_get() does not increment the usage count if it
returns an error. So in the -EACCES case you must not call
pm_runtime_put().

The documentation for pm_runtime_get_sync() says:
 "Consider using pm_runtime_resume_and_get() ...  as this is likely to
 result in cleaner code."

In this case I don't think it results in cleaner code because the
pm_runtime_put() at the end of the function would have to be conditional on
the return value from pm_runtime_resume_and_get() at the top of the
function.

pm_runtime_get_sync() doesn't have this problem because it always
increments the count, so always needs a put. The code can just flow through
and do the pm_runtime_put() unconditionally.

[ Upstream commit 2367e0ecb498764e95cfda691ff0828f7d25f9a4 ]

There are two issues related to the number of ports coming from
Devicetree when exceeding in total QCOM_SDW_MAX_PORTS.  Both lead to
incorrect memory accesses:
1. With DTS having too big value of input or output ports, the driver,
   when copying port parameters from local/stack arrays into 'pconfig'
   array in 'struct qcom_swrm_ctrl', will iterate over their sizes.

2. If DTS also has too many parameters for these ports (e.g.
   qcom,ports-sinterval-low), the driver will overflow buffers on the
   stack when reading these properties from DTS.

Add a sanity check so incorrect DTS will not cause kernel memory
corruption.

When we unbind a serial port hardware specific 8250 driver, the generic
serial8250 driver takes over the port. After that we see an oops about 10

Unhandled fault: imprecise external abort (0x1406)
Internal error: : 1406 [#1] SMP ARM

Turns out that we may still have the serial port hardware specific driver
port->pm in use, and serial8250_pm() tries to call it after the port
specific driver is gone:

serial8250_pm [8250_base] from uart_change_pm+0x54/0x8c [serial_base]

Let's fix the issue by calling serial8250_set_defaults() in
serial8250_unregister_port(). This will set the port back to using
the serial8250 default functions, and sets the port->pm to point to

a battery object. Similarly, if a family of peripherals shares the same

On some ACPI platforms (namely the ASUS Zenbook UM325) the _DSM method must
not be called after a notification is received but instead the mailbox
should be read immediately from RAM. This is because the ACPI interrupt
handler destroys the CCI in ERAM after copying to system memory, and when
_DSM is later called to perform a second copy, it retrieves a garbage
value.

Instead, the _DSM(read) method should only be called when necessary, i.e.
for polling the state after reset and for retrieving the version. Other
reads should not call _DSM and only peek into the RAM region.

This adds a separate read operation for the Zenbook that syncs the
ACPI mailbox only with polled commands.

Bluetooth: hci_bcm: Fall back to getting bdaddr from EFI if not set

[ Upstream commit 0d218c3642b9ccf71f44987cd03c19320f3bd918 ]

On some devices the BCM Bluetooth adapter does not have a valid bdaddr set.

btbcm.c currently sets HCI_QUIRK_INVALID_BDADDR to indicate when this is
the case. But this requires users to manual setup a btaddr, by doing e.g.:

btmgmt -i hci0 public-addr 'B0:F1:EC:82:1D:B3'

Which means that Bluetooth will not work out of the box on such devices.
To avoid this (where possible) hci_bcm sets: HCI_QUIRK_USE_BDADDR_PROPERTY
which tries to get the bdaddr from devicetree.

But this only works on devicetree platforms. On UEFI based platforms
there is a special Broadcom UEFI variable which when present contains
the devices bdaddr, just like how there is another UEFI variable which
contains wifi nvram contents including the wifi MAC address.

Add support for getting the bdaddr from this Broadcom UEFI variable,
so that Bluetooth will work OOTB for users on devices where this
UEFI variable is present.

This fixes Bluetooth not working on for example Asus T100HA 2-in-1s.

[ Upstream commit e3478c68f6704638d08f437cbc552ca5970c151a ]

In ip_vs_sync_conn_v0() copy is made to struct ip_vs_sync_conn_options.
That structure looks like this:

struct ip_vs_sync_conn_options {
        struct ip_vs_seq        in_seq;
        struct ip_vs_seq        out_seq;
};

The source of the copy is the in_seq field of struct ip_vs_conn.  Whose
type is struct ip_vs_seq. Thus we can see that the source - is not as
wide as the amount of data copied, which is the width of struct
ip_vs_sync_conn_option.

The copy is safe because the next field in is another struct ip_vs_seq.
Make use of struct_group() to annotate this.

nbd: fix incomplete validation of ioctl arg

[ Upstream commit 55793ea54d77719a071b1ccc05a05056e3b5e009 ]

We tested and found an alarm caused by nbd_ioctl arg without verification.
The UBSAN warning calltrace like below:

The reason for triggering this warning is __block_write_full_page()
-> i_size_read(inode) - 1 overflow.
inode->i_size is assigned in __nbd_ioctl() -> nbd_set_size() -> bytesize.
We think it is necessary to limit the size of arg to prevent errors.

Moreover, __nbd_ioctl() -> nbd_add_socket(), arg will be cast to int.
Assuming the value of arg is 0x80000000000000001) (on a 64-bit machine),
it will become 1 after the coercion, which will return unexpected results.

Fix it by adding checks to prevent passing in too large numbers.

[ Upstream commit f9fff67d2d7ca6fa8066132003a3deef654c55b1 ]

While running traffics for a long time, randomly an RX descriptor
filled with value "0" from REO destination ring is received.
This descriptor which is invalid causes the wrong SKB (SKB stored in
the IDR lookup with buffer id "0") to be fetched which in turn
causes SKB memory corruption issue and the same leads to crash
after some time.

Changed the start id for idr allocation to "1" and the buffer id "0"
is reserved for error validation. Introduced Sanity check to validate
the descriptor, before processing the SKB.

Crash Signature :

wifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_buf

[ Upstream commit 58d1b717879bfeabe09b35e41ad667c79933eb2e ]

An integer overflow occurs in the iwl_write_to_user_buf() function,
which is called by the iwl_dbgfs_monitor_data_read() function.

static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,
  void *buf, ssize_t *size,
  ssize_t *bytes_copied)
{
int buf_size_left = count - *bytes_copied;

buf_size_left = buf_size_left - (buf_size_left % sizeof(u32));
if (*size > buf_size_left)
*size = buf_size_left;

If the user passes a SIZE_MAX value to the "ssize_t count" parameter,
the ssize_t count parameter is assigned to "int buf_size_left".
Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a
negative number, so "*size" is assigned "buf_size_left" and goes into
the third argument of the copy_to_user function, causing a heap overflow.

This is not a security vulnerability because iwl_dbgfs_monitor_data_read()
is a debugfs operation with 0400 privileges.

md: fix soft lockup in status_resync

[ Upstream commit 6efddf1e32e2a264694766ca485a4f5e04ee82a7 ]

status_resync() will calculate 'curr_resync - recovery_active' to show
user a progress bar like following:

[============>........]  resync = 61.4%

'curr_resync' and 'recovery_active' is updated in md_do_sync(), and
status_resync() can read them concurrently, hence it's possible that
'curr_resync - recovery_active' can overflow to a huge number. In this
case status_resync() will be stuck in the loop to print a large amount
of '=', which will end up soft lockup.

Fix the problem by setting 'resync' to MD_RESYNC_ACTIVE in this case,
this way resync in progress will be reported to user.

13 months agocrypto: jitter - permanent and intermittent health errors
Stephan Müller [Mon, 27 Mar 2023 07:03:52 +0000 (09:03 +0200)]
crypto: jitter - permanent and intermittent health errors

[ Upstream commit 3fde2fe99aa6dacd4151c87382b07ce7f30f0a52 ]

According to SP800-90B, two health failures are allowed: the intermittend
and the permanent failure. So far, only the intermittent failure was
implemented. The permanent failure was achieved by resetting the entire
entropy source including its health test state and waiting for two or
more back-to-back health errors.

This approach is appropriate for RCT, but not for APT as APT has a
non-linear cutoff value. Thus, this patch implements 2 cutoff values
for both RCT/APT. This implies that the health state is left untouched
when an intermittent failure occurs. The noise source is reset
and a new APT powerup-self test is performed. Yet, whith the unchanged
health test state, the counting of failures continues until a permanent
failure is reached.

Any non-failing raw entropy value causes the health tests to reset.

The intermittent error has an unchanged significance level of 2^-30.
The permanent error has a significance level of 2^-60. Considering that
this level also indicates a false-positive rate (see SP800-90B section 4.2)
a false-positive must only be incurred with a low probability when
considering a fleet of Linux kernels as a whole. Hitting the permanent
error may cause a panic(), the following calculation applies: Assuming
that a fleet of 10^9 Linux kernels run concurrently with this patch in
FIPS mode and on each kernel 2 health tests are performed every minute
for one year, the chances of a false positive is about 1:1000
based on the binomial distribution.

In addition, any power-up health test errors triggered with
jent_entropy_init are treated as permanent errors.

A permanent failure causes the entire entropy source to permanently
return an error. This implies that a caller can only remedy the situation
by re-allocating a new instance of the Jitter RNG. In a subsequent
patch, a transparent re-allocation will be provided which also changes
the implied heuristic entropy assessment.

In addition, when the kernel is booted with fips=1, the Jitter RNG
is defined to be part of a FIPS module. The permanent error of the
Jitter RNG is translated as a FIPS module error. In this case, the entire
FIPS module must cease operation. This is implemented in the kernel by
invoking panic().

The patch also fixes an off-by-one in the RCT cutoff value which is now
set to 30 instead of 31. This is because the counting of the values
starts with 0.

ext4: Fix best extent lstart adjustment logic in ext4_mb_new_inode_pa()

[ Upstream commit 93cdf49f6eca5e23f6546b8f28457b2e6a6961d9 ]

When the length of best extent found is less than the length of goal extent
we need to make sure that the best extent atleast covers the start of the
original request. This is done by adjusting the ac_b_ex.fe_logical (logical
start) of the extent.

While doing so, the current logic sometimes results in the best extent's
logical range overflowing the goal extent. Since this best extent is later
added to the inode preallocation list, we have a possibility of introducing
overlapping preallocations. This is discussed in detail here [1].

As per Jan's suggestion, to fix this, replace the existing logic with the
below logic for adjusting best extent as it keeps fragmentation in check
while ensuring logical range of best extent doesn't overflow out of goal
extent:

1. Check if best extent can be kept at end of goal range and still cover
   original start.
2. Else, check if best extent can be kept at start of goal range and still
   cover original start.
3. Else, keep the best extent at start of original request.

Also, add a few extra BUG_ONs that might help catch errors faster.

When calling irq_set_affinity_notifier() with NULL at the notify
argument, it will cause freeing of the glue pointer in the
corresponding array entry but will leave the pointer in the array. A
subsequent call to free_irq_cpu_rmap() will try to free this entry again
leading to possible use after free.

Fix that by setting NULL to the array entry and checking that we have
non-zero at the array entry when iterating over the array in
free_irq_cpu_rmap().

The current code does not suffer from this since there are no cases
where irq_set_affinity_notifier(irq, NULL) (note the NULL passed for the
notify arg) is called, followed by a call to free_irq_cpu_rmap() so we
don't hit and issue. Subsequent patches in this series excersize this

scsi: lpfc: Correct used_rpi count when devloss tmo fires with no recovery

[ Upstream commit db651ec22524eb8f9c854fbb4d9acd5d7e5be9e4 ]

A fabric controller can sometimes send an RDP request right before a link
down event.  Because of this outstanding RDP request, the driver does not
remove the last reference count on its ndlp causing a potential leak of RPI
resources when devloss tmo fires.

In lpfc_cmpl_els_rsp(), modify the NPIV clause to always allow the
lpfc_drop_node() routine to execute when not registered with SCSI
transport.

This relaxes the contraint that an NPIV ndlp must be in a specific state in
order to call lpfc_drop node.  Logic is revised such that the
lpfc_drop_node() routine is always called to ensure the last ndlp decrement
occurs.

[ Upstream commit 35727af2b15d98a2dd2811d631d3a3886111312e ]

The T241 platform suffers from the T241-FABRIC-4 erratum which causes
unexpected behavior in the GIC when multiple transactions are received
simultaneously from different sources. This hardware issue impacts
NVIDIA server platforms that use more than two T241 chips
interconnected. Each chip has support for 320 {E}SPIs.

This issue occurs when multiple packets from different GICs are
incorrectly interleaved at the target chip. The erratum text below
specifies exactly what can cause multiple transfer packets susceptible
to interleaving and GIC state corruption. GIC state corruption can
lead to a range of problems, including kernel panics, and unexpected
behavior.

>From the erratum text:
  "In some cases, inter-socket AXI4 Stream packets with multiple
  transfers, may be interleaved by the fabric when presented to ARM
  Generic Interrupt Controller. GIC expects all transfers of a packet
  to be delivered without any interleaving.

  The following GICv3 commands may result in multiple transfer packets
  over inter-socket AXI4 Stream interface:
   - Register reads from GICD_I* and GICD_N*
   - Register writes to 64-bit GICD registers other than GICD_IROUTERn*
   - ITS command MOVALL

  Multiple commands in GICv4+ utilize multiple transfer packets,
  including VMOVP, VMOVI, VMAPP, and 64-bit register accesses."

  This issue impacts system configurations with more than 2 sockets,
  that require multi-transfer packets to be sent over inter-socket
  AXI4 Stream interface between GIC instances on different sockets.
  GICv4 cannot be supported. GICv3 SW model can only be supported
  with the workaround. Single and Dual socket configurations are not
  impacted by this issue and support GICv3 and GICv4."

Link: https://developer.nvidia.com/docs/t241-fabric-4/nvidia-t241-fabric-4-errata.pdf
Writing to the chip alias region of the GICD_In{E} registers except
GICD_ICENABLERn has an equivalent effect as writing to the global
distributor. The SPI interrupt deactivate path is not impacted by
the erratum.

To fix this problem, implement a workaround that ensures read accesses
to the GICD_In{E} registers are directed to the chip that owns the
SPI, and disable GICv4.x features. To simplify code changes, the
gic_configure_irq() function uses the same alias region for both read
and write operations to GICD_ICFGR.

13 months agodrm/msm/dp: Clean up handling of DP AUX interrupts
Douglas Anderson [Fri, 27 Jan 2023 01:09:12 +0000 (17:09 -0800)]
drm/msm/dp: Clean up handling of DP AUX interrupts

[ Upstream commit b20566cdef05cd40d95f10869d2a7646f48b1bbe ]

The DP AUX interrupt handling was a bit of a mess.
* There were two functions (one for "native" transfers and one for
  "i2c" transfers) that were quite similar. It was hard to say how
  many of the differences between the two functions were on purpose
  and how many of them were just an accident of how they were coded.
* Each function sometimes used "else if" to test for error bits and
  sometimes didn't and again it was hard to say if this was on purpose
  or just an accident.
* The two functions wouldn't notice whether "unknown" bits were
  set. For instance, there seems to be a bit "DP_INTR_PLL_UNLOCKED"
  and if it was set there would be no indication.
* The two functions wouldn't notice if more than one error was set.

Let's fix this by being more consistent / explicit about what we're
doing.

By design this could cause different handling for AUX transfers,
though I'm not actually aware of any bug fixed as a result of
this patch (this patch was created because we simply noticed how odd
the old code was by code inspection). Specific notes here:
1. In the old native transfer case if we got "done + wrong address"
   we'd ignore the "wrong address" (because of the "else if"). Now we
   won't.
2. In the old native transfer case if we got "done + timeout" we'd
   ignore the "timeout" (because of the "else if"). Now we won't.
3. In the old native transfer case we'd see "nack_defer" and translate
   it to the error number for "nack". This differed from the i2c
   transfer case where "nack_defer" was given the error number for
   "nack_defer". This 100% can't matter because the only user of this
   error number treats "nack defer" the same as "nack", so it's clear
   that the difference between the "native" and "i2c" was pointless
   here.
4. In the old i2c transfer case if we got "done" plus any error
   besides "nack" or "defer" then we'd ignore the error. Now we don't.
5. If there is more than one error signaled by the hardware it's
   possible that we'll report a different one than we used to. I don't
   know if this matters. If someone is aware of a case this matters we
   should document it and change the code to make it explicit.
6. One quirk we keep (I don't know if this is important) is that in
   the i2c transfer case if we see "done + defer" we report that as a
   "nack". That seemed too intentional in the old code to just drop.

After this change we will add extra logging, including:
* A warning if we see more than one error bit set.
* A warning if we see an unexpected interrupt.
* A warning if we get an AUX transfer interrupt when shouldn't.

It actually turns out that as a result of this change then at boot we
sometimes see an error:
  [drm:dp_aux_isr] *ERROR* Unexpected DP AUX IRQ 0x01000000 when not busy
That means that, during init, we are seeing DP_INTR_PLL_UNLOCKED. For
now I'm going to say that leaving this error reported in the logs is
OK-ish and hopefully it will encourage someone to track down what's
going on at init time.

One last note here is that this change renames one of the interrupt
bits. The bit named "i2c done" clearly was used for native transfers
being done too, so I renamed it to indicate this.

multiplied by 1000, and assigned to the u64 variable pclk. We can avoid

[Why]
Observing underflow on dcn30+ system config at 4k144hz

[How]
We set the UCLK hardmax on AC/DC switch if softmax is enabled
and also on boot. While booting up the UCLK Hardmax is set
to softmax before the init sequence and the init sequence
resets the hardmax to UCLK max which enables P-state switching.
Just added a conditional check to avoid setting hardmax on init.
