commit 4d92e7c5ccadc79764674ffc2c88d329aabbb7e0 upstream.
When mhi_async_power_up() enables IRQs, it is possible that we could
receive a SYSERR notification from the device if the firmware has crashed
for some reason. Then the SYSERR notification queues a work item that
cannot execute until the pm_mutex is released by mhi_async_power_up().
So the SYSERR work item will be pending. If mhi_async_power_up() detects
the SYSERR, it will handle it. If the device is in PBL, then the PBL state
transition event will be queued, resulting in a work item after the
pending SYSERR work item. Once mhi_async_power_up() releases the pm_mutex,
the SYSERR work item can run. It will blindly attempt to reset the MHI
state machine, which is the recovery action for SYSERR. PBL/SBL are not
interrupt driven and will ignore the MHI Reset unless SYSERR is actively
advertised. This will cause the SYSERR work item to timeout waiting for
reset to be cleared, and will leave the host state in SYSERR processing.
The PBL transition work item will then run, and immediately fail because
SYSERR processing is not a valid state for PBL transition.
This leaves the device uninitialized.
This issue has a fairly unique signature in the kernel log:
mhi mhi3: Requested to power ON
Qualcomm Cloud AI 100 0000:36:00.0: Fatal error received from
device. Attempting to recover
mhi mhi3: Power on setup success
mhi mhi3: Device failed to exit MHI Reset state
mhi mhi3: Device MHI is not in valid state
We cannot remove the SYSERR handling from mhi_async_power_up() because the
device may be in the SYSERR state, but we missed the notification as the
irq was fired before irqs were enabled. We also can't queue the SYSERR work
item from mhi_async_power_up() if SYSERR is detected because that may
result in a duplicate work item, and cause the same issue since the
duplicate item will blindly issue MHI reset even if SYSERR is no longer
active.
Instead, add a check in the SYSERR work item to make sure that MHI reset is
only issued if the device is in SYSERR state for PBL or SBL EEs.

The late init call just writes to omap4 registers as soon as
CONFIG_MFD_CPCAP is enabled without checking whether the
cpcap driver is actually there or the SoC is indeed an
OMAP4.
Rather do these things only with the right device combination.
Fixes booting the BT200 with said configuration enabled and non-factory

arm/memremap: fix arch_memremap_can_ram_remap()
commit 260364d112 ("arm[64]/memremap: don't abuse pfn_valid() to ensure
presence of linear map") added the definition of
arch_memremap_can_ram_remap() for arm[64] specific filtering of what pages
can be used from the linear mapping. memblock_is_map_memory() was called
with the pfn of the address given to arch_memremap_can_ram_remap();
however, memblock_is_map_memory() expects to be given an address for arm,
not a pfn.
This results in calls to memremap() returning a newly mapped area when
it should return an address in the existing linear mapping.
Fix this by removing the address to pfn translation and pass the
address directly.

commit 4b634918384c0f84c33aeb4dd9fd4c38e7be5ccb upstream.
Commit 3ea277194d ("mm, mprotect: flush TLB if potentially racing with
a parallel reclaim leaving stale TLB entries") describes a race that,
prior to the commit, could occur between reclaim and operations such as
mprotect() when using reclaim's tlbbatch mechanism. See that commit for
details but the summary is:
"""
Nadav Amit identified a theoritical race between page reclaim and
mprotect due to TLB flushes being batched outside of the PTL being held.
He described the race as follows:
CPU0 CPU1
---- ----
user accesses memory using RW PTE
[PTE now cached in TLB]
try_to_unmap_one()
==> ptep_get_and_clear()
==> set_tlb_ubc_flush_pending()
mprotect(addr, PROT_READ)
==> change_pte_range()
==> [ PTE non-present - no flush ]
user writes using cached RW PTE
...
try_to_unmap_flush()
"""
The solution was to insert flush_tlb_batched_pending() in mprotect() and
friends to explcitly drain any pending reclaim TLB flushes. In the
modern version of this solution, arch_flush_tlb_batched_pending() is
called to do that synchronisation.
arm64's tlbbatch implementation simply issues TLBIs at queue-time
(arch_tlbbatch_add_pending()), eliding the trailing dsb(ish). The
trailing dsb(ish) is finally issued in arch_tlbbatch_flush() at the end
of the batch to wait for all the issued TLBIs to complete.
Now, the Arm ARM states:
"""
The completion of the TLB maintenance instruction is guaranteed only by
the execution of a DSB by the observer that performed the TLB
maintenance instruction. The execution of a DSB by a different observer
does not have this effect, even if the DSB is known to be executed after
the TLB maintenance instruction is observed by that different observer.
"""
arch_tlbbatch_add_pending() and arch_tlbbatch_flush() conform to this
requirement because they are called from the same task (either kswapd or
caller of madvise(MADV_PAGEOUT)), so either they are on the same CPU or
if the task was migrated, __switch_to() contains an extra dsb(ish).
HOWEVER, arm64's arch_flush_tlb_batched_pending() is also implemented as
a dsb(ish). But this may be running on a CPU remote from the one that
issued the outstanding TLBIs. So there is no architectural gurantee of
synchonization. Therefore we are still vulnerable to the theoretical
race described in Commit 3ea277194d ("mm, mprotect: flush TLB if
potentially racing with a parallel reclaim leaving stale TLB entries").
Fix this by flushing the entire mm in arch_flush_tlb_batched_pending().
This aligns with what the other arches that implement the tlbbatch
feature do.

uvc_gpio_parse() can return -EPROBE_DEFER when the GPIOs it depends on
have not yet been probed. This return code should be propagated to the

Currently, this error code is incorrectly converted to -ENODEV,
causing some internal cameras to be ignored.

v4l2_jpeg_parse_header() will return error, then driver will mark this

But if the error occurs in the first frames, before setup the capture
queue, there is no chance to schedule device_run(), and there may be no
capture to mark error.
So we need to drop this buffer with error flag, and make the decoding
can continue.

Disable ASPM on this combo as a quirk.
This patch is a revision of a previous patch (linked below) which
attempted to disable ASPM for RTL8723BE on all Intel Skylake and Kaby Lake
PCIe bridges. I take a more conservative approach as all known reports
point to ASUSTek laptops of these two generations with this particular
wireless card.
Please note, however, before the rtl8723be finishes probing, the AER
errors remained. After the module finishes probing, all AER errors would
indeed be eliminated, along with heavy lags, poor network throughput,
and/or occasional lock-ups.

commit 490340faddea461319652ce36dbc7c1b4482c35e upstream.
RTL8811AU stops responding during the firmware download on some systems:
[ 809.256440] rtw_8821au 5-2.1:1.0: Firmware version 42.4.0, H2C version 0
[ 812.759142] rtw_8821au 5-2.1:1.0 wlp48s0f4u2u1: renamed from wlan0

[ 897.730952] rtw_8821au 1-4:1.0: write register 0x1efc failed with -110
Each write takes 30 seconds to fail because that's the timeout currently
used for control messages in rtw_usb_write().
In this scenario the firmware download takes at least 2000 seconds.
Because this is done from the USB probe function, the long delay makes
other things in the system hang.
Reduce the timeout to 500 ms. This is the value used by the official USB
wifi drivers from Realtek.
Of course this only makes things hang for ~30 seconds instead of ~30
minutes. It doesn't fix the firmware download.
Tested with RTL8822CU, RTL8812BU, RTL8811CU, RTL8814AU, RTL8811AU,
RTL8812AU, RTL8821AU, RTL8723DU.

commit 6b67d2cf14ea997061f61e9c8afd4e1c0f22acb9 upstream.
Users of the Lenovo ThinkPad X13s have reported that Wi-Fi sometimes
breaks and the log fills up with errors like:
ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1484, expected 1492
ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1460, expected 1484
which based on a quick look at the ath11k driver seemed to indicate some
kind of ring-buffer corruption.
Miaoqing Pan tracked it down to the host seeing the updated destination
ring head pointer before the updated descriptor, and the error handling
for that in turn leaves the ring buffer in an inconsistent state.
While this has not yet been observed with ath12k, the ring-buffer
implementation is very similar to the ath11k one and it suffers from the
same bugs.
Add the missing memory barrier to make sure that the descriptor is read
after the head pointer to address the root cause of the corruption while
fixing up the error handling in case there are ever any (ordering) bugs
on the device side.
Note that the READ_ONCE() are only needed to avoid compiler mischief in
case the ring-buffer helpers are ever inlined.

commit 4c10fa44bc5f700e2ea21de2fbae520ba21f19d9 upstream.
Sometimes, when a file was read while it was being truncated by
another NFS client, the kernel could deadlock because folio_unlock()
was called twice, and the second call would XOR back the `PG_locked`
flag.
Most of the time (depending on the timing of the truncation), nobody
notices the problem because folio_unlock() gets called three times,
which flips `PG_locked` back off:
1. vfs_read, nfs_read_folio, ... nfs_read_add_folio,
nfs_return_empty_folio
2. vfs_read, nfs_read_folio, ... netfs_read_collection,
netfs_unlock_abandoned_read_pages
3. vfs_read, ... nfs_do_read_folio, nfs_read_add_folio,
nfs_return_empty_folio
The problem is that nfs_read_add_folio() is not supposed to unlock the
folio if fscache is enabled, and a nfs_netfs_folio_unlock() check is
missing in nfs_return_empty_folio().
Rarely this leads to a warning in netfs_read_collection():
------------[ cut here ]------------

Most of the time, however, processes just get stuck forever in
folio_wait_bit_common(), waiting for `PG_locked` to disappear, which
never happens because nobody is really holding the folio lock.

commit 0bd2f6b8996d4f1ca4573652454987826730a04a upstream.
Engineers at Hammerspace noticed that sometimes mounting with
"xprtsec=tls" hangs for a minute or so, and then times out, even
when the NFS server is reachable and responsive.
kTLS shuts off data_ready callbacks if strp->msg_ready is set to
mitigate data_ready callbacks when a full TLS record is not yet
ready to be read from the socket.
Normally msg_ready is clear when the first TLS record arrives on
a socket. However, I observed that sometimes tls_setsockopt() sets
strp->msg_ready, and that prevents forward progress because
tls_data_ready() becomes a no-op.
Moreover, Jakub says: "If there's a full record queued at the time
when [tlshd] passes the socket back to the kernel, it's up to the
reader to read the already queued data out." So SunRPC cannot
expect a data_ready call when ingress data is already waiting.
Add an explicit poll after SunRPC's upper transport is set up to
pick up any data that arrived after the TLS handshake but before
transport set-up is complete.

commit b31da62889e6d610114d81dc7a6edbcaa503fcf8 upstream.
In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through
nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized,
this can cause NULL pointer dereference.
Normally the delayed start of laundromat_work allows sufficient time for
nfsd_ssc initialization to complete. However, when the kernel waits too
long for userspace responses (e.g. in nfs4_state_start_net ->
nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->
cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the
delayed work may start before nfsd_ssc initialization finishes.
Fix this by moving nfsd_ssc initialization before starting laundromat_work.

Robert Morris reported:
|If a malicious USB device pretends to be an Intersil p54 wifi
|interface and generates an eeprom_readback message with a large
|eeprom->v1.len, p54_rx_eeprom_readback() will copy data from the

|
|static void p54_rx_eeprom_readback(struct p54_common *priv,

|
| if (priv->fw_var >= 0x509) {

| } else {
| memcpy(priv->eeprom, eeprom->v1.data,
| le16_to_cpu(eeprom->v1.len));
| }
| [...]
The eeprom->v{1,2}.len is set by the driver in p54_download_eeprom().
The device is supposed to provide the same length back to the driver.
But yes, it's possible (like shown in the report) to alter the value
to something that causes a crash/panic due to overrun.
This patch addresses the issue by adding the size to the common device
context, so p54_rx_eeprom_readback no longer relies on possibly tampered
values... That said, it also checks if the "firmware" altered the value
and no longer copies them.
The one, small saving grace is: Before the driver tries to read the eeprom,
it needs to upload >a< firmware. the vendor firmware has a proprietary
license and as a reason, it is not present on most distributions by
default.

commit 9cc0eafd28c7faef300822992bb08d79cab2a36c upstream.
When a system is being suspended to RAM, the PCI devices are also
suspended and the PPC code ends up calling pseries_msi_compose_msg() and
this triggers the BUG_ON() in __pci_read_msi_msg() because the device at
this point is in reduced power state. In reduced power state, the memory
mapped registers of the PCI device are not accessible.
To replicate the bug:
1. Make sure deep sleep is selected
# cat /sys/power/mem_sleep
s2idle [deep]
2. Make sure console is not suspended (so that dmesg logs are visible)
echo N > /sys/module/printk/parameters/console_suspend
3. Suspend the system
echo mem > /sys/power/state
To fix this behaviour, read the cached msi message of the device when the
device is not in PCI_D0 power state instead of touching the hardware.
