5 months agoserial: 8250_dw: Don't use struct dw8250_data outside of 8250_dw
Andy Shevchenko [Tue, 14 May 2024 19:05:53 +0000 (22:05 +0300)]
serial: 8250_dw: Don't use struct dw8250_data outside of 8250_dw

The container of the struct dw8250_port_data is private to the actual
driver. In particular, 8250_lpss and 8250_dw use different data types
that are assigned to the UART port private_data. Hence, it must not
be used outside the specific driver.

Currently the only cpr_val is required by the common code, make it
be available via struct dw8250_port_data.

This fixes the UART breakage on Intel Galileo boards.

5 months agotty: n_tty: Fix buffer offsets when lookahead is used
Ilpo Järvinen [Tue, 14 May 2024 14:04:29 +0000 (17:04 +0300)]
tty: n_tty: Fix buffer offsets when lookahead is used

When lookahead has "consumed" some characters (la_count > 0),
n_tty_receive_buf_standard() and n_tty_receive_buf_closing() for
characters beyond the la_count are given wrong cp/fp offsets which
leads to duplicating and losing some characters.

If la_count > 0, correct buffer pointers and make count consistent too
(the latter is not strictly necessary to fix the issue but seems more
logical to adjust all variables immediately to keep state consistent).

5 months agox86/topology/intel: Unlock CPUID before evaluating anything
Thomas Gleixner [Thu, 30 May 2024 15:29:18 +0000 (17:29 +0200)]
x86/topology/intel: Unlock CPUID before evaluating anything

Intel CPUs have a MSR bit to limit CPUID enumeration to leaf two. If
this bit is set by the BIOS then CPUID evaluation including topology
enumeration does not work correctly as the evaluation code does not try
to analyze any leaf greater than two.

This went unnoticed before because the original topology code just
repeated evaluation several times and managed to overwrite the initial
limited information with the correct one later. The new evaluation code
does it once and therefore ends up with the limited and wrong
information.

Cure this by unlocking CPUID right before evaluating anything which
depends on the maximum CPUID leaf being greater than two instead of
rereading stuff after unlock.

block: Fix zone write plugging handling of devices with a runt zone

A zoned device may have a last sequential write required zone that is
smaller than other zones. However, all tests to check if a zone write
plug write offset exceeds the zone capacity use the same capacity
value stored in the gendisk zone_capacity field. This is incorrect for a
zoned device with a last runt (smaller) zone.

Add the new field last_zone_capacity to struct gendisk to store the
capacity of the last zone of the device. blk_revalidate_seq_zone() and
blk_revalidate_conv_zone() are both modified to get this value when
disk_zone_is_last() returns true. Similarly to zone_capacity, the value
is first stored using the last_zone_capacity field of struct
blk_revalidate_zone_args. Once zone revalidation of all zones is done,
this is used to set the gendisk last_zone_capacity field.

The checks to determine if a zone is full or if a sector offset in a
zone exceeds the zone capacity in disk_should_remove_zone_wplug(),
disk_zone_wplug_abort_unaligned(), blk_zone_write_plug_init_request(),
and blk_zone_wplug_prepare_bio() are modified to use the new helper
functions disk_zone_is_full() and disk_zone_wplug_is_full().
disk_zone_is_full() uses the zone index to determine if the zone being
tested is the last one of the disk and uses the either the disk
zone_capacity or last_zone_capacity accordingly.

a zoned device is constant for all zones. However, this check ignores
the possibility that a zoned device has a smaller last zone with a size

practice to an SMR drive with a smaller last zone and all zones with a

different than the capacity of other zones.

Correctly handle such device by fixing the check for the constant zone
capacity in blk_revalidate_seq_zone() using the new helper function
disk_zone_is_last(). This helper function is also used in

5 months agox86/cpu: Provide default cache line size if not enumerated
Dave Hansen [Fri, 17 May 2024 20:05:34 +0000 (13:05 -0700)]
x86/cpu: Provide default cache line size if not enumerated

tl;dr: CPUs with CPUID.80000008H but without CPUID.01H:EDX[CLFSH]
will end up reporting cache_line_size()==0 and bad things happen.
Fill in a default on those to avoid the problem.

Long Story:

The kernel dies a horrible death if c->x86_cache_alignment (aka.
cache_line_size() is 0.  Normally, this value is populated from
c->x86_clflush_size.

Right now the code is set up to get c->x86_clflush_size from two
places.  First, modern CPUs get it from CPUID.  Old CPUs that don't
have leaf 0x80000008 (or CPUID at all) just get some sane defaults
from the kernel in get_cpu_address_sizes().

The vast majority of CPUs that have leaf 0x80000008 also get
->x86_clflush_size from CPUID.  But there are oddballs.

Intel Quark CPUs[1] and others[2] have leaf 0x80000008 but don't set
CPUID.01H:EDX[CLFSH], so they skip over filling in ->x86_clflush_size:

cpuid(0x00000001, &tfms, &misc, &junk, &cap0);
if (cap0 & (1<<19))
c->x86_clflush_size = ((misc >> 8) & 0xff) * 8;

So they: land in get_cpu_address_sizes() and see that CPUID has level
0x80000008 and jump into the side of the if() that does not fill in
c->x86_clflush_size.  That assigns a 0 to c->x86_cache_alignment, and
hilarity ensues in code like:

        buffer = kzalloc(ALIGN(sizeof(*buffer), cache_line_size()),
                         GFP_KERNEL);

To fix this, always provide a sane value for ->x86_clflush_size.

Big thanks to Andy Shevchenko for finding and reporting this and also
providing a first pass at a fix. But his fix was only partial and only
worked on the Quark CPUs.  It would not, for instance, have worked on
the QEMU config.

1. https://raw.githubusercontent.com/InstLatx64/InstLatx64/master/GenuineIntel/GenuineIntel0000590_Clanton_03_CPUID.txt
2. You can also get this behavior if you use "-cpu 486,+clzero"
   in QEMU.

io_uring/rw: Free iovec before cleaning async data

kmemleak shows that there is a memory leak in io_uring read operation,
where a buffer is allocated at iovec import, but never de-allocated.

The memory is allocated at io_async_rw->free_iovec, but, then
io_async_rw is kfreed, taking the allocated memory with it. I saw this
happening when the read operation fails with -11 (EAGAIN).

This is the kmemleak splat.

This occurs because the async data cleanup functions are not set for
read/write operations. As a result, the potentially allocated iovec in
the rw async data is not freed before the async data is released,
leading to a memory leak.

With this following patch, kmemleak does not show the leaked memory

ASoC: SOF: ipc4-topology: Fix nhlt configuration blob

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

The existing logic to pick a DMIC blob is based on several historical
assumptions that the NHLT in BIOS always contains 32-bits per sample
type (first patch, [1]).

The other issue with the existing logic is that it was designed to care only
about the bit depth of the format and fails to find the existing and correct
blob when rate/channels are different on the FE side compared to what we should
be using on the DAI side (we have components in path which can change
rate/channel count).

These issues have not been observed in past but with new MTL based (Windows)
laptops and new topologies to enhance the audio quality, we started to see weird
issues around how our assumptions of vendors failed.

Since some NHLT blob handling cleanup has been done for 6.10, this series will
complete that work to cover even cases that we don't anticipate to see.

powerpc/uaccess: Use YZ asm constraint for ld

The 'ld' instruction requires a 4-byte aligned displacement because it
is a DS-form instruction. But the "m" asm constraint doesn't enforce
that.

Add a special case of __get_user_asm2_goto() so that the "YZ" constraint
can be used for "ld".

The "Z" constraint is documented in the GCC manual PowerPC machine

indirect addressing". "Y" is not documented in the manual but specifies
a "memory operand for a DS-form instruction". Using both allows the
compiler to generate a DS-form "ld" or X-form "ldx" as appropriate.

The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because
the "Y" constraint does not guarantee 4-byte alignment when prefixed
instructions are enabled.

No build errors have been reported due to this, but the possibility is
there depending on compiler code generation decisions.

The 'std' instruction requires a 4-byte aligned displacement because
it is a DS-form instruction, and as the assembler says, 18 is not a
multiple of 4.

A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y.

The fix is to change the constraint on the memory operand to put_user(),
from "m" which is a general memory reference to "YZ".

The "Z" constraint is documented in the GCC manual PowerPC machine

indirect addressing". "Y" is not documented in the manual but specifies
a "memory operand for a DS-form instruction". Using both allows the
compiler to generate a DS-form "std" or X-form "stdx" as appropriate.

The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because
the "Y" constraint does not guarantee 4-byte alignment when prefixed
instructions are enabled.

Unfortunately clang doesn't support the "Y" constraint so that has to be
behind an ifdef.

Although the build error is only seen with GCC 13/14, that appears
to just be luck. The constraint has been incorrect since it was first
added.

ASoC: SOF: ipc4-topology: Adjust the params based on DAI formats

Currently we only check the bit depth value among to DAI formats, but other
parameters might be constant, like number of channels and/or rate.

In capture we use the fe params as a reference to find the format and blob
which should be used, but in the path we can have components which can
handle expanding/narrowing number of channels or do a resample.

In these cases the topology is expected to have 'fixed' parameter for
channels/rates/bit depth and the conversion to the fe format is going to
be done within the path.

In practice this patch fixes issues like:
All DMIC formats are fixed four channels
We have a component which converts the four channel to stereo
FE is opened with 2 channel

Even if we have the correct bit depth format and blob (for four channel) we
will still be looking for stereo configurations, which will fail.

Note: the adjustment of params have switched order with the checking of
single bit depth (needed for the NHLT blob fallback support). This change
is non function, just that if the sof_ipc4_narrow_params_to_format() would
fail, there is no point of checking the single bit depth.

Patch #4 fixes vlan mangling in skbuff when vlan offload is present
         in skbuff, without this patch nft_payload corrupts packets
         in this case.

Patch #5 fixes possible nul-deref in tproxy no IP address is found in

Patch #6 removes a superfluous restriction which prevents loose fib

My assessment is that patches #1, #2 and #5 address possible kernel

On module load, the ice driver checks for the lack of a specific PF
capability to determine if it should reduce the number of devlink params
to register.  One situation when this test returns true is when the
driver loads in safe mode.  The same check is not present on the unload
path when devlink params are unregistered.  This results in the driver
triggering a WARN_ON in the kernel devlink code.

The current check and code path uses a reduction in the number of elements
reported in the list of params.  This is fragile and not good for future
maintaining.

Change the parameters to be held in two lists, one always registered and
one dependent on the check.

Add a symmetrical check in the unload path so that the correct parameters
are unregistered as well.

e1000e: move force SMBUS near the end of enable_ulp function

The commit 861e8086029e ("e1000e: move force SMBUS from enable ulp
function to avoid PHY loss issue") introduces a regression on
PCH_MTP_I219_LM18 (PCIID: 0x8086550A). Without the referred commit, the
ethernet works well after suspend and resume, but after applying the
commit, the ethernet couldn't work anymore after the resume and the
dmesg shows that the NIC link changes to 10Mbps (1000Mbps originally):

    [   43.305084] e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx

Without the commit, the force SMBUS code will not be executed if
"return 0" or "goto out" is executed in the enable_ulp(), and in my
case, the "goto out" is executed since FWSM_FW_VALID is set. But after
applying the commit, the force SMBUS code will be ran unconditionally.

Here move the force SMBUS code back to enable_ulp() and put it
immediately ahead of hw->phy.ops.release(hw), this could allow the
longest settling time as possible for interface in this function and
doesn't change the original code logic.

The issue was found on a Lenovo laptop with the ethernet hw as below:
00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:550a]
(rev 20).

And this patch is verified (cable plug and unplug, system suspend
and resume) on Lenovo laptops with ethernet hw: [8086:550a],
[8086:550b], [8086:15bb], [8086:15be], [8086:1a1f], [8086:1a1c] and

5 months agonet: fix __dst_negative_advice() race
Eric Dumazet [Tue, 28 May 2024 11:43:53 +0000 (11:43 +0000)]
net: fix __dst_negative_advice() race

__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.

RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).

Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.

Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.

Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.

Many thanks to Clement Lecigne for tracking this issue.

This old bug became visible after the blamed commit, using UDP sockets.
