commit ff2047fb755d4415ec3c70ac799889371151796d upstream.

Drop support for these ioctls:
* PIO_FONT, PIO_FONTX
* GIO_FONT, GIO_FONTX
* PIO_FONTRESET

As was demonstrated by commit 90bfdeef83f1 (tty: make FONTX ioctl use the tty pointer they were actually passed), these ioctls are not used from userspace, as:
1) they used to be broken (set up font on current console, not the open one) and racy (before the commit above)
2) KDFONTOP ioctl is used for years instead

Note that PIO_FONTRESET is defunct on most systems as VGA_CONSOLE is set on them for ages. That turns on BROKEN_GRAPHICS_PROGRAMS which makes PIO_FONTRESET just return an error.

We are removing KD_FONT_FLAG_OLD here as it was used only by these removed ioctls. kd.h header exists both in kernel and uapi headers, so we can remove the kernel one completely. Everyone includeing kd.h will now automatically get the uapi one.

There are now unused definitions of the ioctl numbers and "struct consolefontdesc" in kd.h, but as it is a uapi header, I am not touching these.

commit 534d2eaf1970274150596fdd2bf552721e65d6b2 upstream.

It used to be that mix_interrupt_randomness() would credit 1 bit each time it ran, and so add_interrupt_randomness() would schedule mix() to run every 64 interrupts, a fairly arbitrary number, but nonetheless considered to be a decent enough conservative estimate.

Since e3e33fc2ea7f ("random: do not use input pool from hard IRQs"), mix() is now able to credit multiple bits, depending on the number of calls to add(). This was done for reasons separate from this commit, but it has the nice side effect of enabling this patch to schedule mix() less often.

Currently the rules are:
a) Credit 1 bit for every 64 calls to add().
b) Schedule mix() once a second that add() is called.
c) Schedule mix() once every 64 calls to add().

Rules (a) and (c) no longer need to be coupled. It's still important to have _some_ value in (c), so that we don't "over-saturate" the fast pool, but the once per second we get from rule (b) is a plenty enough baseline. So, by increasing the 64 in rule (c) to something larger, we avoid calling queue_work_on() as frequently during irq storms.

This commit changes that 64 in rule (c) to be 1024, which means we schedule mix() 16 times less often. And it does *not* need to change the 64 in rule (a).

commit 9ae6e8b1c9bbf6874163d1243e393137313762b7 upstream.

During postsuspend dm-era does the following:

1. Archives the current era
2. Commits the metadata, as part of the RPC call for archiving the current era
3. Stops the worker

Until the worker stops, it might write to the metadata again. Moreover, these writes are not flushed to disk immediately, but are cached by the dm-bufio client, which writes them back asynchronously.

As a result, the committed metadata of a suspended dm-era device might not be consistent with the in-core metadata.

In some cases, this can result in the corruption of the on-disk metadata. Suppose the following sequence of events:

1. Load a new table, e.g. a snapshot-origin table, to a device with a dm-era table
2. Suspend the device
3. dm-era commits its metadata, but the worker does a few more metadata writes until it stops, as part of digesting an archived writeset
4. These writes are cached by the dm-bufio client
5. Load the dm-era table to another device.
6. The new instance of the dm-era target loads the committed, on-disk metadata, which don't include the extra writes done by the worker after the metadata commit.
7. Resume the new device
8. The new dm-era target instance starts using the metadata
9. Resume the original device
10. The destructor of the old dm-era target instance is called and destroys the dm-bufio client, which results in flushing the cached writes to disk
11. These writes might overwrite the writes done by the new dm-era instance, hence corrupting its metadata.

Fix this by committing the metadata after the worker stops running.

stop_worker uses flush_workqueue to flush the current work. However, the work item may re-queue itself and flush_workqueue doesn't wait for re-queued works to finish.

This could result in the worker changing the metadata after they have been committed, or writing to the metadata concurrently with the commit in the postsuspend thread.

Use drain_workqueue instead, which waits until the work and all re-queued works finish.

commit c01d4d0a82b71857be7449380338bc53dde2da92 upstream.

random.c ratelimits how much it warns about uninitialized urandom reads using __ratelimit(). When the RNG is finally initialized, it prints the number of missed messages due to ratelimiting.

It has been this way since that functionality was introduced back in 2018. Recently, cc1e127bfa95 ("random: remove ratelimiting for in-kernel unseeded randomness") put a bit more stress on the urandom ratelimiting, which teased out a bug in the implementation.

Specifically, when under pressure, __ratelimit() will print its own message and reset the count back to 0, making the final message at the end less useful. Secondly, it does so as a pr_warn(), which apparently is undesirable for people's CI.

Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly for this purpose, so we set the flag.

commit 15b694e96c31807d8515aacfa687a1e8a4fbbadc upstream.

Add usb product id of the Quectel RM500K module.

RM500K provides 2 mandatory interfaces to Linux host after enumeration.
- /dev/ttyUSB5: this is a serial interface for control path. User needs to write AT commands to this device node to query status, set APN, set PIN code, and enable/disable the data connection to 5G network.
- ethX: this is the data path provided as a RNDIS devices. After the data connection has been established, Linux host can access 5G data network via this interface.

"RNDIS": RNDIS + ADB + AT (/dev/ttyUSB5) + MODEM COMs

The bonding ARP monitor fails to decrement send_peer_notif, the number of peer notifications (gratuitous ARP or ND) to be sent. This results in a continuous series of notifications.

Correct this by decrementing the counter for each notification.

commit 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx") added a function irq_dispatch, and it'll increase irq_err_count when the get_irq callback returns a negative value, but increase irq_err_count in get_irq was not removed.

And also, modpost complains once gpio-vr41xx drivers become modules.
ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined!

So it would be a good idea to remove repetitive increase irq_err_count in get_irq callback.

[ Upstream commit 4e0effd9007ea0be31f7488611eb3824b4541554 ]

Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps.

According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case.

In addition to that, commit b6e0c419f040 ("igb: Move DMA Coalescing init code to separate function.") seems to wrongly changed from enabling E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

commit e5f3205b04d7f95a2ef43bce4b454a7f264d6923 upstream.

IIO trigger interface function iio_trigger_get() should be called after iio_trigger_register() (or its devm analogue) strictly, because of iio_trigger_get() acquires module refcnt based on the trigger->owner pointer, which is initialized inside iio_trigger_register() to THIS_MODULE.
If this call order is wrong, the next iio_trigger_put() (from sysfs callback or "delete module" path) will dereference "default" module refcnt, which is incorrect behaviour.

Since commit 9bcf15f75cac ("iio: adc: axp288: Fix TS-pin handling") we preserve the bias current set by the firmware at boot. This fixes issues we were seeing on various models.

Some models like the Nuvision Solo 10 Draw tablet actually need the old hardcoded 80ųA bias current for battery temperature monitoring to work properly.

Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table to restore setting the bias current to 80ųA on this model.

commit a0117dc956429f2ede17b323046e1968d1849150 upstream.

In calibrate_ccount(), of_find_compatible_node() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.

commit ec6d0dde71d760aa60316f8d1c9a1b0d99213529 upstream.

On execve[at], we are zero'ing out most of the thread register state including gpr[0], which contains the syscall number. Due to this, we fail to trigger the syscall exit tracepoint properly. Fix this by retaining gpr[0] in the thread register state.

commit 7bc08056a6dabc3a1442216daf527edf61ac24b6 upstream.

Add a special case to block_rtas_call() to allow the ibm,platform-dump RTAS call through the RTAS filter if the buffer address is 0.

According to PAPR, ibm,platform-dump is called with a null buffer address to notify the platform firmware that processing of a particular dump is finished.

Without this, on a pseries machine with CONFIG_PPC_RTAS_FILTER enabled, an application such as rtas_errd that is attempting to retrieve a dump will encounter an error at the end of the retrieval process.

commit f3eac426657d985b97c92fa5f7ae1d43f04721f3 upstream.

The platform's RNG must be available before random_init() in order to be useful for initial seeding, which in turn means that it needs to be called from setup_arch(), rather than from an init call.

Complicating things, however, is that POWER8 systems need some per-cpu state and kmalloc, which isn't available at this stage. So we split things up into an early phase and a later opportunistic phase. This commit also removes some noisy log messages that don't add much.

commit 93a8ba2a619816d631bd69e9ce2172b4d7a481b8 upstream.

Contrary to what was believed at the time, the ramp delay of 150us is not plenty for the PU LDO with the default step time of 512 pulses of the 24MHz clock. Measurements have shown that after enabling the LDO the voltage on VDDPU_CAP jumps to ~750mV in the first step and after that the regulator executes the normal ramp up as defined by the step size control.

This means it takes the regulator between 360us and 370us to ramp up to the nominal 1.15V voltage for this power domain. With the old setting of the ramp delay the power up of the PU GPC domain would happen in the middle of the regulator ramp with the voltage being at around 900mV. Apparently this was enough for most units to properly power up the peripherals in the domain and execute the reset. Some units however, fail to power up properly, especially when the chip is at a low temperature. In that case any access to the GPU registers would yield an incorrect result with no way to recover from this situation.

Change the ramp delay to 380us to cover the measured ramp up time with a bit of additional slack.

commit bf22c9ec39da90ce866d5f625d616f28bc733dc1 upstream.

drm_fb_helper_modinit has a lot of boilerplate for what is not very simple functionality. Just open code it in the only caller using IS_ENABLED and IS_MODULE, and skip the find_module check as a request_module is harmless if the module is already loaded (and not other caller has this find_module check either).

commit dbac14a5a05ff8e1ce7c0da0e1f520ce39ec62ea upstream.

EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic.

modpost used to detect it, but it has been broken for a decade.

Recently, I fixed modpost so it started to warn it again, then this showed up in linux-next builds.

There are two ways to fix it:

- Remove __init
- Remove EXPORT_SYMBOL

I chose the latter for this case because none of the in-tree call-sites (arch/arm/xen/enlighten.c, arch/x86/xen/grant-table.c) is compiled as modular.

Commit 428826f5358c ("fdt: add support for rng-seed") moves of_fdt_crc32 from early_init_dt_verify() to early_init_dt_scan() since early_init_dt_scan_chosen() may modify fdt to erase rng-seed.

However, arm and some other arch won't call early_init_dt_scan(), they call early_init_dt_verify() then early_init_dt_scan_nodes().

Restore of_fdt_crc32 to early_init_dt_verify() then update it in early_init_dt_scan_chosen() if fdt if updated.

commit 3e35142ef99fe6b4fe5d834ad43ee13cca10a2dc upstream.

Since commit d1bcae833b32f1 ("ELF: Don't generate unused section symbols") [1], binutils (v2.36+) started dropping section symbols that it thought were unused. This isn't an issue in general, but with kexec_file.c, gcc is placing kexec_arch_apply_relocations[_add] into a separate .text.unlikely section and the section symbol ".text.unlikely" is being dropped. Due to this, recordmcount is unable to find a non-weak symbol in .text.unlikely to generate a relocation record against.

Address this by dropping the weak attribute from these functions. Instead, follow the existing pattern of having architectures #define the name of the function they want to override in their headers.

  * Free up memory used by kernel, initrd, and command line. This is temporary
  * memory allocation which is not needed any more after these buffers have

From: Liu Shixin <[email protected]>

After patch ddbd89deb7d3 ("swiotlb: fix info leak with DMA_FROM_DEVICE"), swiotlb_bounce will be called in swiotlb_tbl_map_single unconditionally. This requires that the physical address must be valid, which is not always true on stable-4.19 or earlier version.
On stable-4.19, swiotlb_alloc_buffer will call swiotlb_tbl_map_single with orig_addr equal to zero, which cause such a panic:

Unable to handle kernel paging request at virtual address ffffb77a40000000
...
pc : __memcpy+0x100/0x180
lr : swiotlb_bounce+0x74/0x88
...
Call trace:
 __memcpy+0x100/0x180
 swiotlb_tbl_map_single+0x2c8/0x338
 swiotlb_alloc+0xb4/0x198
 __dma_alloc+0x84/0x1d8
 ...

On stable-4.9 and stable-4.14, swiotlb_alloc_coherent wille call map_single with orig_addr equal to zero, which can cause same panic.

Fix this by skipping swiotlb_bounce when orig_addr is zero.
