drm/amdgpu: Match against exact bootloader status

[ Upstream commit d3de41ee5febe5c2d9989fe9810bce2bb54a3a8e ]

On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the
least significant bits for any command submission. Hence match against
the exact register value, otherwise a register value of all 0xFFs also
could falsely indicate that boot loader is ready. Also, from PSP v13.0.6
and newer, bits[7:0] will be used to indicate command error status.

[ Upstream commit dd64f80587190265ca8a0f4be6c64c2fda6d3ac2 ]

As &qedi_percpu->p_work_lock is acquired by hard IRQ qedi_msix_handler(),
other acquisitions of the same lock under process context should disable
IRQ, otherwise deadlock could happen if the IRQ preempts the execution
while the lock is held in process context on the same CPU.

qedi_cpu_offline() is one such function which acquires the lock in process
context.

[Deadlock Scenario]
qedi_cpu_offline()
    ->spin_lock(&p->p_work_lock)
        <irq>
        ->qedi_msix_handler()
        ->edi_process_completions()
        ->spin_lock_irqsave(&p->p_work_lock, flags); (deadlock here)

      ppc_md.calibrate_decr() (pmac_calibrate_decr)
        via_calibrate_decr()

ioremap() and iounmap() are called. The unmap can enable interrupts

Using brcmfmac with 6.5-rc3 on a brcmfmac43241b4-sdio triggers
a backtrace caused by the following field-spanning warning:

memcpy: detected field-spanning write (size 120) of single field
  "&params_le->channel_list[0]" at
  drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:1072 (size 2)

The driver still works after this warning. The warning was introduced by the
new field-spanning write checks which were enabled recently.

Fix this by replacing the channel_list[1] declaration at the end of
the struct with a flexible array declaration.

Most users of struct brcmf_scan_params_le calculate the size to alloc
using the size of the non flex-array part of the struct + needed extra
space, so they do not care about sizeof(struct brcmf_scan_params_le).

brcmf_notify_escan_complete() however uses the struct on the stack,
expecting there to be room for at least 1 entry in the channel-list
to store the special -1 abort channel-id.

To make this work use an anonymous union with a padding member
added + the actual channel_list flexible array.

ksz-switch spi1.0 lan1 (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 0

HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS
method. If VGBS is not called on boot, the firmware sends an initial

is booted in the laptop mode. However, if the device is booted in the
tablet mode and VGBS is not called, there is no initial 0xcc event, and
the input device for SW_TABLET_MODE is not registered up until the user
turns the device into the laptop mode.

Call VGBS on boot on this device to get the initial state of
SW_TABLET_MODE in a reliable way.

Note this also makes the intel_button_array_enable() call in probe()

[ Upstream commit 3da435063777f8d861ba5a165344e3f75f839357 ]

Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
USB Link") has a playback and a capture mixer volume/switch, but they
are fairly broken.  The descriptor reports wrong dB ranges for
playback, and the capture volume/switch don't influence on the actual
recording at all.  Moreover, there seem instabilities in the
connection, and at best, we should disable the runtime PM.

So this ended up with a quirk entry for:
- Correct the playback dB range;
  I picked up some reasonable values but it's a guess work
- Disable the capture mixer;
  it's completely useless and confuses PA/PW
- Suppress get-sample-rate, apply the delay for message handling,
  and suppress the auto-suspend

The behavior of the wheel control on the headset is somehow flaky,
too, but it's an issue of HID.

The DASD device driver has a function to requeue requests to the
blocklayer.
This function is used in various cases when basic settings for the device
have to be changed like High Performance Ficon related parameters or copy
pair settings.

The functions iterates over the device->ccw_queue and also removes the
requests from the block->ccw_queue.
In case the device is started on an alias device instead of the base
device it might be removed from the block->ccw_queue without having it
canceled properly before. This might lead to a hanging device since the
request is no longer on a queue and can not be handled properly.

Fix by iterating over the block->ccw_queue instead of the
device->ccw_queue. This will take care of all blocklayer related requests
and handle them on all associated DASD devices.

s390/dasd: use correct number of retries for ERP requests

[ Upstream commit acea28a6b74f458defda7417d2217b051ba7d444 ]

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.

The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Correctly use the number of retries of the original request for ERP
requests.

m68k: Fix invalid .section syntax

[ Upstream commit 922a9bd138101e3e5718f0f4d40dba68ef89bb43 ]

gas supports several different forms for .section for ELF targets,
including:
    .section NAME [, "FLAGS"[, @TYPE[,FLAG_SPECIFIC_ARGUMENTS]]]
and:
    .section "NAME"[, #FLAGS...]

In several places we use a mix of these two forms:
    .section NAME, #FLAGS...

A current development snapshot of binutils (2.40.50.20230611) treats
this mixed syntax as an error.

Change to consistently use:
    .section NAME, "FLAGS"
as is used elsewhere in the kernel.

da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just

still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.

This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

which indicates that the AAD IRQ handler is unexpectedly running when

over I2C and is hitting the I2C driver "Transfer while suspended"
failure.

However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending

unexpectedly generated after jack detection is already disabled.

14 months agonilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuse
Ryusuke Konishi [Fri, 18 Aug 2023 13:18:04 +0000 (22:18 +0900)]
nilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuse

commit cdaac8e7e5a059f9b5e816cda257f08d0abffacd upstream.

A syzbot stress test using a corrupted disk image reported that
mark_buffer_dirty() called from __nilfs_mark_inode_dirty() or
nilfs_palloc_commit_alloc_entry() may output a kernel warning, and can
panic if the kernel is booted with panic_on_warn.

This is because nilfs2 keeps buffer pointers in local structures for some
metadata and reuses them, but such buffers may be forcibly discarded by
nilfs_clear_dirty_page() in some critical situations.

This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do
not write dirty data after degenerating to read-only"), but the issue has
potentially existed before.

Fix this issue by checking the uptodate flag when attempting to reuse an
internally held buffer, and reloading the metadata instead of reusing the
buffer if the flag was lost.

commit f83913f8c5b882a312e72b7669762f8a5c9385e4 upstream.

A syzbot stress test reported that create_empty_buffers() called from
nilfs_lookup_dirty_data_buffers() can cause a general protection fault.

Analysis using its reproducer revealed that the back reference "mapping"

Fix this issue by excluding pages/folios from being collected if, after
acquiring a lock on each page/folio, its back reference "mapping" differs
from the pointer to the address space struct that held the page/folio.

serial: sc16is7xx: fix bug when first setting GPIO direction

commit 9baeea723c0fb9c3ba9a336369f758ed9bc6831d upstream.

When configuring a pin as an output pin with a value of logic 0, we
end up as having a value of logic 1 on the output pin. Setting a
logic 0 a second time (or more) after that will correctly output a
logic 0 on the output pin.

By default, all GPIO pins are configured as inputs. When we enter
sc16is7xx_gpio_direction_output() for the first time, we first set the
desired value in IOSTATE, and then we configure the pin as an output.
The datasheet states that writing to IOSTATE register will trigger a
transfer of the value to the I/O pin configured as output, so if the
pin is configured as an input, nothing will be transferred.

Therefore, set the direction first in IODIR, and then set the desired
value in IOSTATE.

This is what is done in NXP application note AN10587.

serial: sc16is7xx: fix broken port 0 uart init

commit 2861ed4d6e6d1a2c9de9bf5b0abd996c2dc673d0 upstream.

The sc16is7xx_config_rs485() function is called only for the second
port (index 1, channel B), causing initialization problems for the
first port.

For the sc16is7xx driver, port->membase and port->mapbase are not set,
and their default values are 0. And we set port->iobase to the device
index. This means that when the first device is registered using the
uart_add_one_port() function, the following values will be in the port
structure:
    port->membase = 0
    port->mapbase = 0
    port->iobase  = 0

Therefore, the function uart_configure_port() in serial_core.c will
exit early because of the following check:
/*
 * If there isn't a port here, don't do anything further.
 */
if (!port->iobase && !port->mapbase && !port->membase)
return;

Typically, I2C and SPI drivers do not set port->membase and
port->mapbase.

The max310x driver sets port->membase to ~0 (all ones). By
implementing the same change in this driver, uart_configure_port() is
now correctly executed for all ports.

ALSA: usb-audio: Fix init call orders for UAC1

commit 5fadc941d07530d681f3b7ec91e56d8445bc3825 upstream.

There have been reports of USB-audio driver spewing errors at the
probe time on a few devices like Jabra and Logitech.  The suggested
fix there couldn't be applied as is, unfortunately, because it'll
likely break other devices.

But, the patch suggested an interesting point: looking at the current
init code in stream.c, one may notice that it does initialize
differently from the device setup in endpoint.c.  Namely, for UAC1, we
should call snd_usb_init_pitch() and snd_usb_init_sample_rate() after
setting the interface, while the init sequence at parsing calls them
before setting the interface blindly.

This patch changes the init sequence at parsing for UAC1 (and other
devices that need a similar behavior) to be aligned with the rest of
the code, setting the interface at first.  And, this fixes the
long-standing problems on a few UAC1 devices like Jabra / Logitech,
as reported, too.

14 months agomodules: only allow symbol_get of EXPORT_SYMBOL_GPL modules

modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules

commit 9011e49d54dcc7653ebb8a1e05b5badb5ecfa9f9 upstream.

It has recently come to my attention that nvidia is circumventing the
protection added in 262e6ae7081d ("modules: inherit
TAINT_PROPRIETARY_MODULE") by importing exports from their proprietary
modules into an allegedly GPL licensed module and then rexporting them.

Given that symbol_get was only ever intended for tightly cooperating
modules using very internal symbols it is logical to restrict it to
being used on EXPORT_SYMBOL_GPL and prevent nvidia from costly DMCA
Circumvention of Access Controls law suites.

All symbols except for four used through symbol_get were already exported
as EXPORT_SYMBOL_GPL, and the remaining four ones were switched over in
the preparation patches.

erofs: ensure that the post-EOF tails are all zeroed

commit e4c1cf523d820730a86cae2c6d55924833b6f7ac upstream.

This was accidentally fixed up in commit e4c1cf523d82 but we can't
take the full change due to other dependancy issues, so here is just
the actual bugfix that is needed.

[Background]

keltargw reported an issue [1] that with mmaped I/Os, sometimes the
tail of the last page (after file ends) is not filled with zeroes.

The root cause is that such tail page could be wrongly selected for
inplace I/Os so the zeroed part will then be filled with compressed
data instead of zeroes.

A simple fix is to avoid doing inplace I/Os for such tail parts,
actually that was already fixed upstream in commit e4c1cf523d82
("erofs: tidy up z_erofs_do_read_page()") by accident.

kallsyms: Fix kallsyms_selftest failure

commit 33f0467fe06934d5e4ea6e24ce2b9c65ce618e26 upstream.

Kernel test robot reported a kallsyms_test failure when clang lto is
enabled (thin or full) and CONFIG_KALLSYMS_SELFTEST is also enabled.
I can reproduce in my local environment with the following error message
with thin lto:
  [    1.877897] kallsyms_selftest: Test for 1750th symbol failed: (tsc_cs_mark_unstable) addr=ffffffff81038090
  [    1.877901] kallsyms_selftest: abort

It appears that commit 8cc32a9bbf29 ("kallsyms: strip LTO-only suffixes
from promoted global functions") caused the failure. Commit 8cc32a9bbf29
changed cleanup_symbol_name() based on ".llvm." instead of '.' where
".llvm." is appended to a before-lto-optimization local symbol name.
We need to propagate such knowledge in kallsyms_selftest.c as well.

Further more, compare_symbol_name() in kallsyms.c needs change as well.
In scripts/kallsyms.c, kallsyms_names and kallsyms_seqs_of_names are used
to record symbol names themselves and index to symbol names respectively.
For example:
  kallsyms_names:
    ...
    __amd_smn_rw._entry       <== seq 1000
    __amd_smn_rw._entry.5     <== seq 1001
    __amd_smn_rw.llvm.<hash>  <== seq 1002
    ...

kallsyms_seqs_of_names are sorted based on cleanup_symbol_name() through, so
the order in kallsyms_seqs_of_names actually has

  index 1000:   seq 1002   <== __amd_smn_rw.llvm.<hash> (actual symbol comparison using '__amd_smn_rw')
  index 1001:   seq 1000   <== __amd_smn_rw._entry
  index 1002:   seq 1001   <== __amd_smn_rw._entry.5

Let us say at a particular point, at index 1000, symbol '__amd_smn_rw.llvm.<hash>'
is comparing to '__amd_smn_rw._entry' where '__amd_smn_rw._entry' is the one to
search e.g., with function kallsyms_on_each_match_symbol(). The current implementation
will find out '__amd_smn_rw._entry' is less than '__amd_smn_rw.llvm.<hash>' and
then continue to search e.g., index 999 and never found a match although the actual
index 1001 is a match.

To fix this issue, let us do cleanup_symbol_name() first and then do comparison.
In the above case, comparing '__amd_smn_rw' vs '__amd_smn_rw._entry' and
'__amd_smn_rw._entry' being greater than '__amd_smn_rw', the next comparison will
be > index 1000 and eventually index 1001 will be hit an a match is found.

For any symbols not having '.llvm.' substr, there is no functionality change
for compare_symbol_name().

commit 567b35159e76997e95b643b9a8a5d9d2198f2522 upstream.

This change simplifies the randomization of file mapping regions. It
reworks the code to remove duplication. The flow is now similar to
that for mips. Finally, we consistently use the do_color_align variable
to determine when color alignment is needed.

Tested on rp3440.

lockdep: fix static memory detection even more

commit 0a6b58c5cd0dfd7961e725212f0fc8dfc5d96195 upstream.

On the parisc architecture, lockdep reports for all static objects which
are in the __initdata section (e.g. "setup_done" in devtmpfs,
"kthreadd_done" in init/main.c) this warning:

INFO: trying to register non-static key.

The warning itself is wrong, because those objects are in the __initdata
section, but the section itself is on parisc outside of range from
_stext to _end, which is why the static_obj() functions returns a wrong
answer.

While fixing this issue, I noticed that the whole existing check can
be simplified a lot.
Instead of checking against the _stext and _end symbols (which include
code areas too) just check for the .data and .bss segments (since we check a
data object). This can be done with the existing is_kernel_core_data()
macro.

In addition objects in the __initdata section can be checked with
init_section_contains(), and is_kernel_rodata() allows keys to be in the
_ro_after_init section.

This partly reverts and simplifies commit bac59d18c701 ("x86/setup: Fix static
memory detection").
