s390: remove the unneeded select GCC12_NO_ARRAY_BOUNDS

Commit 0da6e5fd6c37 ("gcc: disable '-Warray-bounds' for gcc-13 too") makes
config GCC11_NO_ARRAY_BOUNDS to be for disabling -Warray-bounds in any gcc
version 11 and upwards, and with that, removes the GCC12_NO_ARRAY_BOUNDS
config as it is now covered by the semantics of GCC11_NO_ARRAY_BOUNDS.

As GCC11_NO_ARRAY_BOUNDS is yes by default, there is no need for the s390
architecture to explicitly select GCC11_NO_ARRAY_BOUNDS. Hence, the select
GCC12_NO_ARRAY_BOUNDS in arch/s390/Kconfig can simply be dropped.

Remove the unneeded "select GCC12_NO_ARRAY_BOUNDS".

Merge branch 'x86-uaccess-cleanup': x86 uaccess header cleanups

Merge my x86 uaccess updates branch.

The LAM ("Linear Address Masking") updates in this release made me
unhappy about how "access_ok()" was done, and it actually turned out to
have a couple of small bugs in it too.  This is my cleanup of the code:

 - use the sign bit of the __user pointer rather than masking the
   address and checking it against the TASK_SIZE range.

   We already did this part for the get/put_user() side, but
   'access_ok()' did the naïve "mask and range check" thing, which not
   only generates nasty code, but also ended up meaning that __access_ok
   itself didn't do a good job, and so copy_from_user_nmi() didn't get
   the check right.

 - move all the code that is 64-bit only into the 64-bit version of the
   header file, so that we don't unnecessarily pollute the shared x86
   code and make it look like LAM might work in 32-bit too.

 - fix a bug in the address masking (that doesn't end up mattering: in
   this case the fix was to just remove the buggy code entirely).

 - a couple of trivial cleanups and added commentary about the
   access_ok() rules.

* x86-uaccess-cleanup:
  x86-64: mm: clarify the 'positive addresses' user address rules
  x86: mm: remove 'sign' games from LAM untagged_addr*() macros

When replacing a filter (i.e. 'fold' pointer is not NULL) the insertion of
new filter to idr is postponed until later in code since handle is already
provided by the user. However, the error handling code in fl_change()
always assumes that the new filter had been inserted into idr. If error
handler is reached when replacing existing filter it may remove it from idr
therefore making it unreachable for delete or dump afterwards. Fix the
issue by verifying that 'fold' argument wasn't provided by caller before
calling idr_remove().

net/sched: flower: fix filter idr initialization

The cited commit moved idr initialization too early in fl_change() which
allows concurrent users to access the filter that is still being
initialized and is in inconsistent state, which, in turn, can cause NULL
pointer dereference [0]. Since there is no obvious way to fix the ordering
without reverting the whole cited commit, alternative approach taken to
first insert NULL pointer into idr in order to allocate the handle but
still cause fl_get() to return NULL and prevent concurrent users from
seeing the filter while providing miss-to-action infrastructure with valid
handle id early in fl_change().

18 months agonet: dsa: mt7530: fix network connectivity with multiple CPU ports
Arınç ÜNAL [Tue, 2 May 2023 21:09:47 +0000 (00:09 +0300)]
net: dsa: mt7530: fix network connectivity with multiple CPU ports

On mt753x_cpu_port_enable() there's code that enables flooding for the CPU
port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports
are enabled, port 6 becomes the only port to forward the frames to. But
port 5 is the active port, so no frames received from the user ports will
be forwarded to port 5 which breaks network connectivity.

Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix
this issue by setting the bit that corresponds to the CPU port without
overwriting the other bits.

Clear the bits beforehand only for the MT7531 switch. According to the
documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference
Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and
UNU_FFP bits are set to 1 for MT7531, 0 for MT7530.

The commit 5e5502e012b8 ("net: dsa: mt7530: fix roaming from DSA user
ports") silently changed the method to set the bits on the MT7530_MFC.
Instead of clearing the relevant bits before mt7530_cpu_port_enable()
which runs under a for loop, the commit started doing it on
mt7530_cpu_port_enable().

Back then, this didn't really matter as only a single CPU port could be
used since the CPU port number was hardcoded. The driver was later changed
with commit 1f9a6abecf53 ("net: dsa: mt7530: get cpu-port via dp->cpu_dp
instead of constant") to retrieve the CPU port via dp->cpu_dp. With that,
this silent change became an issue for when using multiple CPU ports.

Arınç ÜNAL [Tue, 2 May 2023 21:09:46 +0000 (00:09 +0300)]
net: dsa: mt7530: fix corrupt frames using trgmii on 40 MHz XTAL MT7621

The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.

This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.

My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.

Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.

Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.

Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.

This NULL pointer access happens in the powercap core idle-inject
function idle_inject_set_duration() as there is no NULL check for
idle_inject_device pointer. This pointer must be allocated by calling
idle_inject_register() or idle_inject_register_full().

In the function powerclamp_set_cur_state(), idle_inject_device pointer
is allocated only when the cur_state > 0. But setting 0 without changing
to any other state, idle_inject_set_duration() will be called with a
NULL idle_inject_device pointer.

To address this, just return from powerclamp_set_cur_state() if the
current cooling device state is the same as the last one. Since the
power-up default cooling device state is 0, changing the state to 0
again here will return without calling idle_inject_set_duration().

ACPI: video: Remove acpi_backlight=video quirk for Lenovo ThinkPad W530

Remove the acpi_backlight=video quirk for Lenovo ThinkPad W530.

This was intended to help users of the (unsupported) Nvidia binary driver,
but this has been reported to cause backlight control issues for users
who have the gfx configured in hybrid (dual-GPU) mode, so drop this.

The Nvidia binary driver should call acpi_video_register_backlight()
when necessary and this has been reported to Nvidia.

Until this is fixed Nvidia binary driver users can work around this by
passing "acpi_backlight=video" on the kernel commandline (with the latest
6.1.y or newer stable series, kernels < 6.1.y don't need this).

Fix a potential race in gmap_make_secure() and remove the last user of

The old code is locking something it doesn't have a reference to, and
as explained by Jason and David in this discussion:
https://lore.kernel.org/linux-mm/Y9J4P%2FRNvY1Ztn0Q@nvidia.com/
it can lead to all kind of bad things, including the page getting
unmapped (MADV_DONTNEED), freed, reallocated as a larger folio and the
unlock_page() would target the wrong bit.
There is also another race with the FOLL_WRITE, which could race
between the follow_page() and the get_locked_pte().

The main point is to remove the last use of follow_page() without

KVM: s390: pv: fix asynchronous teardown for small VMs

On machines without the Destroy Secure Configuration Fast UVC, the
topmost level of page tables is set aside and freed asynchronously
as last step of the asynchronous teardown.

Each gmap has a host_to_guest radix tree mapping host (userspace)
addresses (with 1M granularity) to gmap segment table entries (pmds).

If a guest is smaller than 2GB, the topmost level of page tables is the
segment table (i.e. there are only 2 levels). Replacing it means that
the pointers in the host_to_guest mapping would become stale and cause
all kinds of nasty issues.

This patch fixes the issue by disallowing asynchronous teardown for
guests with only 2 levels of page tables. Userspace should (and already
does) try using the normal destroy if the asynchronous one fails.

Update s390_replace_asce so it refuses to replace segment type ASCEs.

[Why]
The selfring doorbell aperture will change when resize FB
BAR successfully during gmc sw init, we should reorder
the sequence of enabling doorbell selfring aperture.

[How]
Move enable_doorbell_selfring_aperture from *_common_hw_init

This fixes the potential issue that GPU ring its own
