PATCH 1/191 iov_iter, x86: Be consistent about the __user tag on copy_mc_to_user()

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: David Howells <[email protected]>

[ Upstream commit 066baf92bed934c9fb4bcee97a193f47aa63431c ]

copy_mc_to_user() has the destination marked __user on powerpc, but not on x86; the latter results in a sparse warning in lib/iov_iter.c.

Fix this by applying the tag on x86 too.

Fixes ec6347bb4339 ("x86, powerpc: Rename memcpy_mcsafe() to copy_mc_to_{user, kernel}()")

PATCH 2/191 sched/uclamp: Ignore (util == 0) optimization in feec() when p_util_max = 0

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Qais Yousef <[email protected]>

[ Upstream commit 23c9519def98ee0fa97ea5871535e9b136f522fc ]

find_energy_efficient_cpu() bails out early if effective util of the task is 0 as the delta at this point will be zero and there's nothing for EAS to do. When uclamp is being used, this could lead to wrong decisions when uclamp_max is set to 0. In this case the task is capped to performance point 0, but it is actually running and consuming energy and we can benefit from EAS energy calculations.

Rework the condition so that it bails out when both util and uclamp_min are 0.

We can do that without needing to use uclamp_task_util(); remove it.

Fixes d81304bc6193 ("sched/uclamp: Cater for uclamp in find_energy_efficient_cpu()'s early exit condition")

PATCH 3/191 vfs: fix readahead(2) on block devices

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Reuben Hawkins <[email protected]>

[ Upstream commit 7116c0af4b8414b2f19fdb366eea213cbd9d91c2 ]

Readahead was factored to call generic_fadvise. That refactor added an S_ISREG restriction which broke readahead on block devices.

In addition to S_ISREG, this change checks S_ISBLK to fix block device readahead. There is no change in behavior with any file type besides block devices in this change.

PATCH 5/191 futex: Dont include process MM in futex key on no-MMU

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ben Wolsieffer <[email protected]>

[ Upstream commit c73801ae4f22b390228ebf471d55668e824198b6 ]

On no-MMU, all futexes are treated as private because there is no need to map a virtual address to physical to match the futex across processes. This doesn't quite work though, because private futexes include the current process's mm_struct as part of their key. This makes it impossible for one process to wake up a shared futex being waited on in another process.

Fix this bug by excluding the mm_struct from the key. With a single address space, the futex address is already a unique key.

PATCH 8/191 genirq/matrix: Exclude managed interrupts in irq_matrix_allocated()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Chen Yu <[email protected]>

[ Upstream commit a0b0bad10587ae2948a7c36ca4ffc206007fbcf3 ]

When a CPU is about to be offlined, x86 validates that all active interrupts which are targeted to this CPU can be migrated to the remaining online CPUs. If not, the offline operation is aborted.

The validation uses irq_matrix_allocated() to retrieve the number of vectors which are allocated on the outgoing CPU. The returned number of allocated vectors includes also vectors which are associated to managed interrupts.

That's overaccounting because managed interrupts are:

- not migrated when the affinity mask of the interrupt targets only the outgoing CPU

- migrated to another CPU, but in that case the vector is already pre-allocated on the potential target CPUs and must not be taken into account.

As a consequence the check whether the remaining online CPUs have enough capacity for migrating the allocated vectors from the outgoing CPU might fail incorrectly.

Let irq_matrix_allocated() return only the number of allocated non-managed interrupts to make this validation check correct.

PATCH 10/191 wifi: iwlwifi: Use FW rate for non-data frames

In reply to Greg Kroah-Hartman

------------------

From: Miri Korenblit <[email protected]>

[ Upstream commit 499d02790495958506a64f37ceda7e97345a50a8 ]

Currently we are setting the rate in the tx cmd for mgmt frames (e.g. during connection establishment). This was problematic when sending mgmt frames in eSR mode, as we don't know what link this frame will be sent on (This is decided by the FW), so we don't know what is the lowest rate.
Fix this by not setting the rate in tx cmd and rely
on FW to choose the right one.
Set rate only for injected frames with fixed rate,
or when no sta is given.
Also set for important frames (EAPOL etc.) the High Priority flag.

PATCH 12/191 tcp: call tcp_try_undo_recovery when an RTOd TFO SYNACK is ACKed

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Aananth V <[email protected]>

[ Upstream commit e326578a21414738de45f77badd332fb00bd0f58 ]

For passive TCP Fast Open sockets that had SYN/ACK timeout and did not send more data in SYN_RECV, upon receiving the final ACK in 3WHS, the congestion state may awkwardly stay in CA_Loss mode unless the CA state was undone due to TCP timestamp checks. However, if tcp_rcv_synrecv_state_fastopen() decides not to undo, then we should enter CA_Open, because at that point we have received an ACK covering the retransmitted SYNACKs. Currently, the icsk_ca_state is only set to CA_Open after we receive an ACK for a data-packet. This is because tcp_ack does not call tcp_fastretrans_alert (and tcp_process_loss) if !prior_packets

Note that tcp_process_loss() calls tcp_try_undo_recovery(), so having tcp_rcv_synrecv_state_fastopen() decide that if we're in CA_Loss we should call tcp_try_undo_recovery() is consistent with that, and low risk.

PATCH 13/191 overflow: Implement size_t saturating arithmetic helpers

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kees Cook <[email protected]>

[ Upstream commit e1be43d9b5d0d1310dbd90185a8e5c7145dde40f ]

In order to perform more open-coded replacements of common allocation size arithmetic, the kernel needs saturating (SIZE_MAX) helpers for multiplication, addition, and subtraction. For example, it is common in allocators, especially on realloc, to add to an existing size:

    p = krealloc(map->patch,
                 sizeof(struct reg_sequence) * (map->patch_regs + num_regs),
                 GFP_KERNEL);

There is no existing saturating replacement for this calculation, and just leaving the addition open coded inside array_size() could potentially overflow as well. For example, an overflow in an expression for a size_t argument might wrap to zero:

    array_size(anything, something_at_size_max + 1) == 0

Introduce size_mul(), size_add(), and size_sub() helpers that implicitly promote arguments to size_t and saturated calculations for use in allocations. With these helpers it is also possible to redefine array_size(), array3_size(), flex_array_size(), and struct_size() in terms of the new helpers.

As with the check_*_overflow() helpers, the new helpers use __must_check, though what is really desired is a way to make sure that assignment is only to a size_t lvalue. Without this, it's still possible to introduce overflow/underflow via type conversion (i.e. from size_t to int). Enforcing this will currently need to be left to static analysis or future use of -Wconversion.

Additionally update the overflow unit tests to force runtime evaluation for the pathological cases.

PATCH 14/191 gve: Use size_add() in call to struct_size()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

PATCH 19/191 wifi: mt76: mt7603: rework/fix rx pse hang check

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <[email protected]>

[ Upstream commit baa19b2e4b7bbb509a7ca7939c8785477dcd40ee ]

It turns out that the code in mt7603_rx_pse_busy() does not detect actual hardware hangs, it only checks for busy conditions in PSE.
A reset should only be performed if these conditions are true and if there is no rx activity as well.
Reset the counter whenever a rx interrupt occurs. In order to also deal with a fully loaded CPU that leaves interrupts disabled with continuous NAPI polling, also check for pending rx interrupts in the function itself.

PATCH 24/191 can: dev: can_restart(): dont crash kernel if carrier is OK

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Marc Kleine-Budde <[email protected]>

[ Upstream commit fe5c9940dfd8ba0c73672dddb30acd1b7a11d4c7 ]

During testing, I triggered a can_restart() with the netif carrier being OK [1]. The BUG_ON, which checks if the carrier is OK, results in a fatal kernel crash. This is neither helpful for debugging nor for a production system.

[1] The root cause is a race condition in can_restart() which will be fixed in the next patch.

Do not crash the kernel, issue an error message instead, and continue restarting the CAN device anyway.

This race condition was discovered while updating the at91_can driver to use can_bus_off(). The following scenario describes how the converted at91_can driver would behave.

When a CAN device goes into BUS-OFF state, the driver usually stops/resets the CAN device and calls can_bus_off().

This function sets the netif carrier to off, and (if configured by user space) schedules a delayed work that calls can_restart() to restart the CAN device.

The can_restart() function first checks if the carrier is off and triggers an error message if the carrier is OK.

Then it calls the driver's do_set_mode() function to restart the device, then it sets the netif carrier to on. There is a race window between these two calls.

The at91 CAN controller (observed on the sama5d3, a single core 32 bit ARM CPU) has a hardware limitation. If the device goes into bus-off while sending a CAN frame, there is no way to abort the sending of this frame. After the controller is enabled again, another attempt is made to send it.

If the bus is still faulty, the device immediately goes back to the bus-off state. The driver calls can_bus_off(), the netif carrier is switched off and another can_restart is scheduled. This occurs within the race window before the original can_restart() handler marks the netif carrier as OK. This would cause the 2nd can_restart() to be called with an OK netif carrier, resulting in an error message.

The flow of the 1st can_restart() looks like this:

can_restart()

    // bail out if netif_carrier is OK

    netif_carrier_ok(dev)
    priv->do_set_mode(dev, CAN_MODE_START)
        // enable CAN controller
        // sama5d3 restarts sending old message

        // CAN devices goes into BUS_OFF, triggers IRQ

// IRQ handler start

    at91_irq()
        at91_irq_err_line()
            can_bus_off()
                netif_carrier_off()
                schedule_delayed_work()

// IRQ handler end

netif_carrier_on()

The 2nd can_restart() will be called with an OK netif carrier and the error message will be printed.

To close the race window, first set the netif carrier to on, then restart the controller. In case the restart fails with an error code, roll back the netif carrier to off.

PATCH 28/191 r8169: use tp_to_dev instead of open code

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Juhee Kang <[email protected]>

[ Upstream commit 4b6c6065fca123d419afef005a696f51e6590470 ]

The open code is defined as a helper function(tp_to_dev) on r8169_main.c, which the open code is &tp->pci_dev->dev. The helper function was added in commit 1e1205b7d3e9 ("r8169: add helper tp_to_dev"). And then later, commit f1e911d5d0df ("r8169: add basic phylib support") added r8169_phylink_handler function but it didn't use the helper function. Thus, tp_to_dev() replaces the open code. This patch doesn't change logic.

In reply to Greg Kroah-Hartman

------------------

From: Heiner Kallweit <[email protected]>

[ Upstream commit 621735f590643e3048ca2060c285b80551660601 ]

In very rare cases (I've seen two reports so far about different RTL8125 chip versions) it seems the MAC locks up when link goes down and requires a software reset to get revived.
Realtek doesn't publish hw errata information, therefore the root cause is unknown. Realtek vendor drivers do a full hw re-initialization on each link-up event, the slimmed-down variant here was reported to fix the issue for the reporting user.
It's not fully clear which parts of the NIC are reset as part of the software reset, therefore I can't rule out side effects.

PATCH 31/191 tcp: fix cookie_init_timestamp() overflows

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <[email protected]>

[ Upstream commit 73ed8e03388d16c12fc577e5c700b58a29045a15 ]

cookie_init_timestamp() is supposed to return a 64bit timestamp suitable for both TSval determination and setting of skb->tstamp.

Unfortunately it uses 32bit fields and overflows after 2^32 * 10^6 nsec (~49 days) of uptime.

Generated TSval are still correct, but skb->tstamp might be set far away in the past, potentially confusing other layers.

tcp_ns_to_ts() is changed to return a full 64bit value, ts and ts_now variables are changed to u64 type, and TSMASK is removed in favor of shifts operations.

While we are at it, change this sequence:

		ts >>= TSBITS;
		ts--;
		ts <<= TSBITS;
		ts |= options;
to:
		ts -= (1UL << TSBITS);

PATCH 32/191 ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <[email protected]>

[ Upstream commit 48cf49d31994ff97b33c4044e618560ec84d35fb ]

snprintf() does not return negative values on error.

To know if the buffer was too small, the returned value needs to be compared with the length of the passed buffer. If it is greater or equal, the output has been truncated, so add checks for the truncation to create_pnp_modalias() and create_of_modalias(). Also make them return -ENOMEM in that case, as they already do that elsewhere.

Moreover, the remaining size of the buffer used by snprintf() needs to be updated after the first write to avoid out-of-bounds access as already done correctly in create_pnp_modalias(), but not in create_of_modalias(), so change the latter accordingly.

Fixes 8765c5ba1949 ("ACPI / scan: Rework modalias creation when "compatible" is present")

PATCH 33/191 ipv6: avoid atomic fragment on GSO packets

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Yan Zhai <[email protected]>

[ Upstream commit 03d6c848bfb406e9ef6d9846d759e97beaeea113 ]

When the ipv6 stack output a GSO packet, if its gso_size is larger than dst MTU, then all segments would be fragmented. However, it is possible for a GSO packet to have a trailing segment with smaller actual size than both gso_size as well as the MTU, which leads to an "atomic fragment". Atomic fragments are considered harmful in RFC-8021. An Existing report from APNIC also shows that atomic fragments are more likely to be dropped even it is equivalent to a no-op [1].

Add an extra check in the GSO slow output path. For each segment from the original over-sized packet, if it fits with the path MTU, then avoid generating an atomic fragment.

PATCH 35/191 ipvlan: properly track tx_errors

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <[email protected]>

[ Upstream commit ff672b9ffeb3f82135488ac16c5c5eb4b992999b ]

Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound() increment dev->stats.tx_errors in case of errors.

Unfortunately there are two issues :

1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.

2) Increments are not atomic. KCSAN would complain eventually.

Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64() to copy the value back to user.

PATCH 36/191 regmap: debugfs: Fix a erroneous check after snprintf()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <[email protected]>

[ Upstream commit d3601857e14de6369f00ae19564f1d817d175d19 ]

This error handling looks really strange.
Check if the string has been truncated instead.

PATCH 37/191 clk: qcom: clk-rcg2: Fix clock rate overflow for high parent frequencies

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Devi Priya <[email protected]>

[ Upstream commit f7b7d30158cff246667273bd2a62fc93ee0725d2 ]

If the parent clock rate is greater than unsigned long max/2 then integer overflow happens when calculating the clock rate on 32-bit systems. As RCG2 uses half integer dividers, the clock rate is first being multiplied by 2 which will overflow the unsigned long max value. Hence, replace the common pattern of doing 64-bit multiplication and then a do_div() call with simpler mult_frac call.

Fixes bcd61c0f535a ("clk: qcom: Add support for root clock generators (RCGs)")

PATCH 38/191 clk: qcom: mmcc-msm8998: Add hardware clockgating registers to some clks

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: AngeloGioacchino Del Regno <[email protected]>

[ Upstream commit fa92f3b093d6ca624f42d444d5a206f8724b6bb3 ]

Hardware clock gating is supported on some of the clocks declared in
there: ignoring that it does exist may lead to unstabilities on some firmwares.
Add the HWCG registers where applicable to stop potential crashes.

This was verified on a smartphone shipped with a recent MSM8998 firmware, which will experience random crashes without this change.

[ Upstream commit 9906c4140897bbdbff7bb71c6ae67903cb9954ce ]

Some branch clocks are governed externally and we're only supposed to send a request concerning their shutdown, not actually ensure it happens.

Use the BRANCH_HALT_SKIP define to skip checking the halt bit.

From: AngeloGioacchino Del Regno <[email protected]>

[ Upstream commit 68e1d106eb4dceb61bc2818d829786b364fd502b ]

This GDSC enables (or cuts!) power to the Multimedia Subsystem IOMMU (mmss smmu), which has bootloader pre-set secure contexts. In the event of a complete power loss, the secure contexts will be reset and the hypervisor will crash the SoC.

To prevent this, and get a working multimedia subsystem, set this GDSC as always on.

PATCH 44/191 clk: imx: Select MXC_CLK for CLK_IMX8QXP

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Abel Vesa <[email protected]>

[ Upstream commit 317e69c49b4ceef8aebb47d771498ccb3571bdf9 ]

If the i.MX8QXP clock provider is built-in but the MXC_CLK is built as module, build fails:

aarch64-linux-ld: drivers/clk/imx/clk-imx8-acm.o: in function `imx8_acm_clk_probe':
clk-imx8-acm.c:(.text+0x3d0): undefined reference to `imx_check_clk_hws'

Fix that by selecting MXC_CLK in case of CLK_IMX8QXP.

PATCH 46/191 clk: asm9260: use parent index to link the reference clock

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dmitry Baryshkov <[email protected]>

[ Upstream commit f5290d8e4f0caa81a491448a27dd70e726095d07 ]

Rewrite clk-asm9260 to use parent index to use the reference clock. During this rework two helpers are added:

- clk_hw_register_mux_table_parent_data() to supplement clk_hw_register_mux_table() but using parent_data instead of parent_names

- clk_hw_register_fixed_rate_parent_accuracy() to be used instead of directly calling __clk_hw_register_fixed_rate(). The later function is an internal API, which is better not to be called directly.

Stable-dep-of: 84aefafe6b29 ("clk: linux/clk-provider.h: fix kernel-doc warnings and typos")

PATCH 48/191 spi: nxp-fspi: use the correct ioremap function

In reply to Greg Kroah-Hartman

From: Han Xu <[email protected]>

[ Upstream commit c3aa5cb264a38ae9bbcce32abca4c155af0456df ]

AHB memory as MMIO should be mapped with ioremap rather than ioremap_wc, which should have been used initially just to handle unaligned access as a workaround.

PATCH 53/191 clk: ti: change ti_clk_register[_omap_hw]() API

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dario Binacchi <[email protected]>

[ Upstream commit 3400d546a741a2b2001d88e7fa29110d45a3930d ]

The ti_clk_register() and ti_clk_register_omap_hw() functions are always called with the parameter of type "struct device" set to NULL, since the functions from which they are called always have a parameter of type "struct device_node". Replacing "struct device" type parameter with "struct device_node" will allow you to register a TI clock to the common clock framework by taking advantage of the facilities provided by the "struct device_node" type. Further, adding the "of_" prefix to the name of these functions explicitly binds them to the "struct device_node" type.

The patch has been tested on a Beaglebone board.

Stable-dep-of: 7af5b9eadd64 ("clk: ti: fix double free in of_ti_divider_clk_setup()")

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <[email protected]>

[ Upstream commit 7af5b9eadd64c9e02a71f97c45bcdf3b64841f6b ]

The "div" pointer is freed in _register_divider() and again in of_ti_divider_clk_setup(). Delete the free in _register_divider()

Fixes fbbc18591585 ("clk: ti: divider: cleanup _register_divider and ti_clk_get_div_table")

PATCH 55/191 clk: npcm7xx: Fix incorrect kfree

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jonathan Neuschäfer <[email protected]>

[ Upstream commit bbc5080bef4a245106aa8e8d424ba8847ca7c0ca ]

The corresponding allocation is:

Quoted 2 lines

npcm7xx_clk_data = kzalloc(struct_size(npcm7xx_clk_data, hws,

			     NPCM7XX_NUM_CLOCKS), GFP_KERNEL);

... so, kfree should be applied to npcm7xx_clk_data, not npcm7xx_clk_data->hws.

PATCH 63/191 platform/x86: wmi: Fix probe failure when failing to register WMI devices

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Armin Wolf <[email protected]>

[ Upstream commit ed85891a276edaf7a867de0e9acd0837bc3008f2 ]

When a WMI device besides the first one somehow fails to register, retval is returned while still containing a negative error code. This causes the ACPI device fail to probe, leaving behind zombie WMI devices leading to various errors later.

Handle the single error path separately and return 0 unconditionally after trying to register all WMI devices to solve the issue. Also continue to register WMI devices even if some fail to allocate memory.

Fixes 6ee50aaa9a20 ("platform/x86: wmi: Instantiate all devices before adding them")

PATCH 65/191 platform/x86: wmi: Fix opening of char device

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Armin Wolf <[email protected]>

[ Upstream commit eba9ac7abab91c8f6d351460239108bef5e7a0b6 ]

Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices().

Fix the problem by using the miscdevice pointer to retrieve the WMI device data associated with a char device using container_of(). This also avoids wmi_char_open() picking a wrong WMI device bound to a driver with the same name as the original driver.

Fixes 44b6b7661132 ("platform/x86: wmi: create userspace interface for drivers")

PATCH 66/191 hwmon: (axi-fan-control) Support temperature vs pwm points

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nuno Sá <[email protected]>

[ Upstream commit 2aee7e67bee7a5aa741bad6a0a472f108b29ad40 ]

The HW has some predefined points where it will associate a PWM value. However some users might want to better set these points to their usecases. This patch exposes these points as pwm auto_points:

PATCH 67/191 hwmon: (axi-fan-control) Fix possible NULL pointer dereference

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dragos Bogdan <[email protected]>

[ Upstream commit 2a5b3370a1d9750eca325292e291c8c7cb8cf2e0 ]

axi_fan_control_irq_handler(), dependent on the private axi_fan_control_data structure, might be called before the hwmon device is registered. That will cause an "Unable to handle kernel NULL pointer dereference" error.

Given that

PATCH 73/191 drm/bridge: tc358768: Disable non-continuous clock mode

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dmitry Osipenko <[email protected]>

[ Upstream commit fbc5a90e82c1131869e76ce5b082693b8a75c121 ]

Non-continuous clock mode doesn't work because driver doesn't support it properly. The bridge driver programs wrong bitfields that are required by the non-continuous mode (BTACNTRL1 register bitfields are swapped in the code), but fixing them doesn't help.

Display panel of ASUS Transformer TF700T tablet supports non-continuous mode and display doesn't work at all using that mode. There are no device-trees that are actively using this DSI bridge in upstream yet, so clearly the broken mode wasn't ever tested properly. It's a bit too difficult to get LP mode working, hence let's disable the offending mode for now and fall back to continuous mode.

PATCH 74/191 drm/bridge: tc358768: Fix bit updates

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Tomi Valkeinen <[email protected]>

[ Upstream commit 66962d5c3c51377b9b90cae35b7e038950438e02 ]

The driver has a few places where it does:

if (thing_is_enabled_in_config)
update_thing_bit_in_hw()

This means that if the thing is _not_ enabled, the bit never gets cleared. This affects the h/vsyncs and continuous DSI clock bits.

Fix the driver to always update the bit.

PATCH 75/191 drm/mediatek: Fix iommu fault during crtc enabling

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jason-JH.Lin <[email protected]>

[ Upstream commit 53412dc2905401207f264dc30890f6b9e41524a6 ]

The difference between drm_atomic_helper_commit_tail() and drm_atomic_helper_commit_tail_rpm() is drm_atomic_helper_commit_tail() will commit plane first and then enable crtc, drm_atomic_helper_commit_tail_rpm() will enable crtc first and then commit plane.

Before mediatek-drm enables crtc, the power and clk required by OVL have not been turned on, so the commit plane cannot be committed before crtc is enabled. That means OVL layer should not be enabled before crtc is enabled.
Therefore, the atomic_commit_tail of mediatek-drm is hooked with drm_atomic_helper_commit_tail_rpm().

Another reason is that the plane_state of drm_atomic_state is not synchronized with the plane_state stored in mtk_crtc during crtc enablng, so just set all planes to disabled.

PATCH 76/191 drm/rockchip: cdn-dp: Fix some error handling paths in cdn_dp_probe()

In reply to Greg Kroah-Hartman

cdn_dp_audio_codec_init() can fail. So add some error handling.

If component_add() fails, the previous cdn_dp_audio_codec_init() call should be undone, as already done in the remove function.

PATCH 77/191 arm64/arm: xen: enlighten: Fix KPTI checks

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mark Rutland <[email protected]>

[ Upstream commit 20f3b8eafe0ba5d3c69d5011a9b07739e9645132 ]

When KPTI is in use, we cannot register a runstate region as XEN requires that this is always a valid VA, which we cannot guarantee. Due to this, xen_starting_cpu() must avoid registering each CPU's runstate region, and xen_guest_init() must avoid setting up features that depend upon it.

We tried to ensure that in commit:

f88af7229f6f22ce (" xen/arm: do not setup the runstate info page if kpti is enabled")

... where we added checks for xen_kernel_unmapped_at_usr(), which wraps arm64_kernel_unmapped_at_el0() on arm64 and is always false on 32-bit arm.

Unfortunately, as xen_guest_init() is an early_initcall, this happens before secondary CPUs are booted and arm64 has finalized the ARM64_UNMAP_KERNEL_AT_EL0 cpucap which backs arm64_kernel_unmapped_at_el0(), and so this can subsequently be set as secondary CPUs are onlined. On a big.LITTLE system where the boot CPU does not require KPTI but some secondary CPUs do, this will result in xen_guest_init() intializing features that depend on the runstate region, and xen_starting_cpu() registering the runstate region on some CPUs before KPTI is subsequent enabled, resulting the the problems the aforementioned commit tried to avoid.

Handle this more robsutly by deferring the initialization of the runstate region until secondary CPUs have been initialized and the ARM64_UNMAP_KERNEL_AT_EL0 cpucap has been finalized. The per-cpu work is moved into a new hotplug starting function which is registered later when we're certain that KPTI will not be used.

Fixes f88af7229f6f ("xen/arm: do not setup the runstate info page if kpti is enabled")

PATCH 78/191 drm/rockchip: Fix type promotion bug in rockchip_gem_iommu_map()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <[email protected]>

[ Upstream commit 6471da5ee311d53ef46eebcb7725bc94266cc0cf ]

The "ret" variable is declared as ssize_t and it can hold negative error codes but the "rk_obj->base.size" variable is type size_t. This means that when we compare them, they are both type promoted to size_t and the negative error code becomes a high unsigned value and is treated as success. Add a cast to fix this.

PATCH 79/191 xen-pciback: Consider INTx disabled when MSI/MSI-X is enabled

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Marek Marczykowski-Górecki <[email protected]>

[ Upstream commit 2c269f42d0f382743ab230308b836ffe5ae9b2ae ]

Linux enables MSI-X before disabling INTx, but keeps MSI-X masked until the table is filled. Then it disables INTx just before clearing MASKALL bit. Currently this approach is rejected by xen-pciback. According to the PCIe spec, device cannot use INTx when MSI/MSI-X is enabled (in other words: enabling MSI/MSI-X implicitly disables INTx).

Change the logic to consider INTx disabled if MSI/MSI-X is enabled. This applies to three places:
- checking currently enabled interrupts type,
- transition to MSI/MSI-X - where INTx would be implicitly disabled,
- clearing INTx disable bit - which can be allowed even if MSI/MSI-X is enabled, as device should consider INTx disabled anyway in that case

PATCH 84/191 firmware: ti_sci: Mark driver as non removable

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dhruva Gole <[email protected]>

[ Upstream commit 7b7a224b1ba1703583b25a3641ad9798f34d832a ]

The TI-SCI message protocol provides a way to communicate between various compute processors with a central system controller entity. It provides the fundamental device management capability and clock control in the SOCs that it's used in.

The remove function failed to do all the necessary cleanup if there are registered users. Some things are freed however which likely results in an oops later on.

Ensure that the driver isn't unbound by suppressing its bind and unbind sysfs attributes. As the driver is built-in there is no way to remove device once bound.

We can also remove the ti_sci_remove call along with the ti_sci_debugfs_destroy as there are no callers for it any longer.

PATCH 86/191 selftests/pidfd: Fix ksft print formats

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Maciej Wieczor-Retman <[email protected]>

[ Upstream commit 4d7f4e8158b62f63031510cdc24acc520956c091 ]

Compiling pidfd selftest after adding a __printf() attribute to ksft_print_msg() and ksft_test_result_pass() exposes -Wformat warnings in error_report(), test_pidfd_poll_exec_thread(), child_poll_exec_test(), test_pidfd_poll_leader_exit_thread(), child_poll_leader_exit_test().

The ksft_test_result_pass() in error_report() expects a string but doesn't provide any argument after the format string. All the other calls to ksft_print_msg() in the functions mentioned above have format strings that don't match with other passed arguments.

Fix format specifiers so they match the passed variables.

Add a missing variable to ksft_test_result_pass() inside error_report() so it matches other cases in the switch statement.

Fixes 2def297ec7fb ("pidfd: add tests for NSpid info in fdinfo")

PATCH 87/191 selftests/resctrl: Ensure the benchmark commands fits to its array

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ilpo Järvinen <[email protected]>

[ Upstream commit 4a28c7665c2a1ac0400864eabb0c641e135f61aa ]

Benchmark command is copied into an array in the stack. The array is BENCHMARK_ARGS items long but the command line could try to provide a longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63 bytes of space after fitting the terminating \0 character) and user could have inputted argument longer than that.

Return error in case the benchmark command does not fit to the space allocated for it.

PATCH 89/191 hwrng: geode - fix accessing registers

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jonas Gorski <[email protected]>

[ Upstream commit 464bd8ec2f06707f3773676a1bd2c64832a3c805 ]

When the membase and pci_dev pointer were moved to a new struct in priv, the actual membase users were left untouched, and they started reading out arbitrary memory behind the struct instead of registers. This unfortunately turned the RNG into a constant number generator, depending on the content of what was at that offset.

To fix this, update geode_rng_data_{read,present}() to also get the membase via amd_geode_priv, and properly read from the right addresses again.

PATCH 91/191 nd_btt: Make BTT lanes preemptible

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Tomas Glozar <[email protected]>

[ Upstream commit 36c75ce3bd299878fd9b238e9803d3817ddafbf3 ]

nd_region_acquire_lane uses get_cpu, which disables preemption. This is an issue on PREEMPT_RT kernels, since btt_write_pg and also nd_region_acquire_lane itself take a spin lock, resulting in BUG:
sleeping function called from invalid context.

Fix the issue by replacing get_cpu with smp_process_id and migrate_disable when needed. This makes BTT operations preemptible, thus permitting the use of spin_lock.

BUG example occurring when running ndctl tests on PREEMPT_RT kernel:

PATCH 95/191 crypto: qat - increase size of buffers

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Giovanni Cabiddu <[email protected]>

[ Upstream commit 4e4e2ed22d505c5bacf65c6a39bfb6d120d24785 ]

Increase the size of the buffers used for composing the names used for the transport debugfs entries and the vector name to avoid a potential truncation.

This resolves the following errors when compiling the driver with W=1 and KCFLAGS=-Werror on GCC 12.3.1:

drivers/crypto/intel/qat/qat_common/adf_transport_debug.c: In function ‘adf_ring_debugfs_add’:
drivers/crypto/intel/qat/qat_common/adf_transport_debug.c:100:60: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=] drivers/crypto/intel/qat/qat_common/adf_isr.c: In function ‘adf_isr_resource_alloc’:

PATCH 96/191 hid: cp2112: Fix duplicate workqueue initialization

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Danny Kaehn <[email protected]>

[ Upstream commit e3c2d2d144c082dd71596953193adf9891491f42 ]

Previously the cp2112 driver called INIT_DELAYED_WORK within cp2112_gpio_irq_startup, resulting in duplicate initilizations of the workqueue on subsequent IRQ startups following an initial request. This resulted in a warning in set_work_data in workqueue.c, as well as a rare NULL dereference within process_one_work in workqueue.c.

Initialize the workqueue within _probe instead.

PATCH 97/191 ARM: 9321/1: memset: cast the constant byte to unsigned char

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Kursad Oney <[email protected]>

[ Upstream commit c0e824661f443b8cab3897006c1bbc69fd0e7bc4 ]

memset() description in ISO/IEC 9899:1999 (and elsewhere) says:

The memset function copies the value of c (converted to an unsigned char) into each of the first n characters of the object pointed to by s.

The kernel's arm32 memset does not cast c to unsigned char. This results in the following code to produce erroneous output:

	char a[128];
	memset(a, -128, sizeof(a));

This is because gcc will generally emit the following code before it calls memset() :

	mov   r0, r7
	mvn   r1, #127        ; 0x7f
	bl    00000000 <memset>

r1 ends up with 0xffffff80 before being used by memset() and the 'a' array will have -128 once in every four bytes while the other bytes will be set incorrectly to -1 like this (printing the first 8 bytes) :

	test_module: -128 -1 -1 -1
	test_module: -1 -1 -1 -128

The change here is to 'and' r1 with 255 before it is used.

PATCH 100/191 IB/mlx5: Fix rdma counter binding for RAW QP

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Patrisious Haddad <[email protected]>

[ Upstream commit c1336bb4aa5e809a622a87d74311275514086596 ]

Previously when we had a RAW QP, we bound a counter to it when it moved to INIT state, using the counter context inside RQC.

But when we try to modify that counter later in RTS state we used modify QP which tries to change the counter inside QPC instead of RQC.

Now we correctly modify the counter set_id inside of RQC instead of QPC for the RAW QP.

PATCH 101/191 RDMA/hns: Fix uninitialized ucmd in hns_roce_create_qp_common()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Chengchang Tang <[email protected]>

[ Upstream commit c64e9710f9241e38a1c761ed1c1a30854784da66 ]

ucmd in hns_roce_create_qp_common() are not initialized. But it works fine until new member sdb_addr is added to struct hns_roce_ib_create_qp.

If the user-mode driver uses an old version ABI, then the value of the new member will be undefined after ib_copy_from_udata().

This patch fixes it by initialize this variable to 0. And the default value of the new member sdb_addr will be 0 which is invalid.

[ Upstream commit a75a16c62a2540f11eeae4f2b50e95deefb652ea ]

utf16s_to_utf8s does not NULL terminate the output string. For us to be able to add a NULL character when utf16s_to_utf8s returns, we need to make sure that there is space for such NULL character at the end of the output buffer. We can achieve this by passing an output buffer size to utf16s_to_utf8s that is one character less than what we allocated.

Other call sites of utf16s_to_utf8s appear to be using the same technique where they artificially reduce the buffer size by one to leave space for a NULL character or line feed character.

PATCH 106/191 hid: cp2112: Fix IRQ shutdown stopping polling for all IRQs on chip

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Danny Kaehn <[email protected]>

[ Upstream commit dc3115e6c5d9863ec1a9ff1acf004ede93c34361 ]

Previously cp2112_gpio_irq_shutdown() always cancelled the gpio_poll_worker, even if other IRQs were still active, and did not set the gpio_poll flag to false. This resulted in any call to _shutdown() resulting in interrupts no longer functioning on the chip until a _remove() occurred (a.e. the cp2112 is unplugged or system rebooted).

Only cancel polling if all IRQs are disabled/masked, and correctly set the gpio_poll flag, allowing polling to restart when an interrupt is next enabled.

PATCH 107/191 sh: bios: Revive earlyprintk support

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <[email protected]>

[ Upstream commit 553f7ac78fbb41b2c93ab9b9d78e42274d27daa9 ]

The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK. However, when this protection was added, it was missed that SuperH no longer defines an EARLY_PRINTK config symbol since commit e76fe57447e88916 ("sh: Remove old early serial console code V2"), so BIOS earlyprintk can no longer be used.

Fix this by reviving the EARLY_PRINTK config symbol.

PATCH 108/191 Revert "HID: logitech-hidpp: add a module parameter to keep firmware gestures"

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Bastien Nocera <[email protected]>

[ Upstream commit cae253d6033da885e71c29c1591b22838a52de76 ]

Now that we're in 2022, and the majority of desktop environments can and should support touchpad gestures through libinput, remove the legacy module parameter that made it possible to use gestures implemented in firmware.

This will eventually allow simplifying the driver's initialisation code.

This reverts commit 9188dbaed68a4b23dc96eba165265c08caa7dc2a.

PATCH 109/191 HID: logitech-hidpp: Remove HIDPP_QUIRK_NO_HIDINPUT quirk

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Bastien Nocera <[email protected]>

[ Upstream commit d83956c8855c6c2ed4bd16cec4a5083d63df17e4 ]

HIDPP_QUIRK_NO_HIDINPUT isn't used by any devices but still happens to work as HIDPP_QUIRK_DELAYED_INIT is defined to the same value. Remove HIDPP_QUIRK_NO_HIDINPUT and use HIDPP_QUIRK_DELAYED_INIT everywhere instead.

Tested on a T650 which requires that quirk, and a number of unifying and Bluetooth devices that don't.

PATCH 110/191 HID: logitech-hidpp: Dont restart IO, instead defer hid_connect() only

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hans de Goede <[email protected]>

[ Upstream commit 11ca0322a41920df2b462d2e45b0731e47ff475b ]

Restarting IO causes 2 problems:

1. Some devices do not like IO being restarted this was addressed in commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication if not necessary"), but that change has issues of its own and needs to be reverted.

2. Restarting IO and specifically calling hid_device_io_stop() causes received packets to be missed, which may cause connect-events to get missed.

Restarting IO was introduced in commit 91cf9a98ae41 ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and serial number and store these in hdev->name and hdev->uniq before connecting any hid subdrivers (hid-input, hidraw) exporting this info to userspace.

But this does not require restarting IO, this merely requires deferring calling hid_connect(). Calling hid_hw_start() with a connect-mask of 0 makes it skip calling hid_connect(), so hidpp_probe() can simply call hid_connect() later without needing to restart IO.

Remove the stop + restart of IO and instead just call hid_connect() later to avoid the issues caused by restarting IO.

Now that IO is no longer stopped, hid_hw_close() must be called at the end of probe() to balance the hid_hw_open() done at the beginning probe().

This series has been tested on the following devices:
Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0) Logitech M720 Triathlon (bluetooth, HID++ 4.5)
Logitech M720 Triathlon (unifying, HID++ 4.5)
Logitech K400 Pro (unifying, HID++ 4.1)

Logitech LX501 keyboard (27 Mhz, HID++ builtin scroll-wheel, HID++ 1.0) Logitech M-RAZ105 mouse (27 Mhz, HID++ extra mouse buttons, HID++ 1.0)

And by bentiss:
Logitech Touchpad T650 (unifying)
Logitech Touchpad T651 (bluetooth)
Logitech MX Master 3B (BLE)
Logitech G403 (plain USB / Gaming receiver)

PATCH 111/191 HID: logitech-hidpp: Revert "Dont restart communication if not necessary"

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hans de Goede <[email protected]>

[ Upstream commit 55bf70362ffc4ddd7c8745e2fe880edac00e4aff ]

Commit 91cf9a98ae41 ("HID: logitech-hidpp: make .probe usbhid capable") makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO without connecting any hid subdrivers (hid-input, hidraw).

This is done to allow to retrieve the device's name and serial number and store these in hdev->name and hdev->uniq.

Then later on IO was stopped and started again with hid_hw_start(hdev, HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name and serial number have been setup.

Commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication if not necessary") changed the probe() code to only do the start with a 0 connect-mask + restart later for unifying devices.

But for non unifying devices hdev->name and hdev->uniq are updated too. So this change re-introduces the problem for which the start with a 0 connect-mask + restart later behavior was introduced.

The previous patch in this series changes the unifying path to instead of restarting IO only call hid_connect() later. This avoids possible issues with restarting IO seen on non unifying devices.

Revert the change to limit the restart behavior to unifying devices to fix hdev->name changing after userspace facing devices have already been registered.

This series has been tested on the following devices:
Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0) Logitech M720 Triathlon (bluetooth, HID++ 4.5)

PATCH 112/191 HID: logitech-hidpp: Move get_wireless_feature_index() check to hidpp_connect_event()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hans de Goede <[email protected]>

[ Upstream commit ba9de350509504fb748837b71e23d7e84c83d93c ]

Calling get_wireless_feature_index() from probe() causes the wireless_feature_index to only get set for unifying devices which are already connected at probe() time. It does not get set for devices which connect later.

Fix this by moving get_wireless_feature_index() to hidpp_connect_event(), this does not make a difference for devices connected at probe() since probe() will queue the hidpp_connect_event() for those at probe time.

PATCH 115/191 padata: Fix refcnt handling in padata_free_shell()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: WangJinchao <[email protected]>

[ Upstream commit 7ddc21e317b360c3444de3023bcc83b85fabae2f ]

In a high-load arm64 environment, the pcrypt_aead01 test in LTP can lead to system UAF (Use-After-Free) issues. Due to the lengthy analysis of the pcrypt_aead01 function call, I'll describe the problem scenario using a simplified model:

Suppose there's a user of padata named user_function that adheres to the padata requirement of calling padata_free_shell after serial() has been invoked, as demonstrated in the following code:

```c
struct request {
    struct padata_priv padata;
    struct completion *done;
};

void parallel(struct padata_priv *padata) {
    do_something();
}

void serial(struct padata_priv *padata) {
    struct request *request = container_of(padata,
    				struct request,
				padata);
    complete(request->done);
}

void user_function() {
    DECLARE_COMPLETION(done)
    padata->parallel = parallel;
    padata->serial = serial;
    padata_do_parallel();
    wait_for_completion(&done);
    padata_free_shell();
}
```

In the corresponding padata.c file, there's the following code:

```c
static void padata_serial_worker(struct work_struct *serial_work) {
    ...
    cnt = 0;

    while (!list_empty(&local_list)) {
        ...
        padata->serial(padata);
        cnt++;
    }

    local_bh_enable();

    if (refcount_sub_and_test(cnt, &pd->refcnt))
        padata_free_pd(pd);
}
```

Because of the high system load and the accumulation of unexecuted softirq at this moment, local_bh_enable() in padata takes longer to execute than usual. Subsequently, when accessing pd->refcnt, pd has already been released by padata_free_shell(), resulting in a UAF issue with pd->refcnt.

The fix is straightforward: add refcount_dec_and_test before calling padata_free_pd in padata_free_shell.

Fixes 07928d9bfc81 ("padata: Remove broken queue flushing")

PATCH 118/191 mfd: core: Ensure disabled devices are skipped without aborting

In reply to Greg Kroah-Hartman

From: Herve Codina <[email protected]>

[ Upstream commit 7ba7bdef4d14e3722e2842da3b48cbadb73e52d6 ]

The loop searching for a matching device based on its compatible string is aborted when a matching disabled device is found. This abort prevents to add devices as soon as one disabled device is found.

Continue searching for an other device instead of aborting on the first disabled one fixes the issue.

PATCH 120/191 leds: pwm: Dont disable the PWM when the LED should be off

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Uwe Kleine-König <[email protected]>

[ Upstream commit 76fe464c8e64e71b2e4af11edeef0e5d85eeb6aa ]

Disabling a PWM (i.e. calling pwm_apply_state with .enabled = false) gives no guarantees what the PWM output does. It might freeze where it currently is, or go in a High-Z state or drive the active or inactive state, it might even continue to toggle.

To ensure that the LED gets really disabled, don't disable the PWM even when .duty_cycle is zero.

This fixes disabling a leds-pwm LED on i.MX28. The PWM on this SoC is one of those that freezes its output on disable, so if you disable an LED that is full on, it stays on. If you disable a LED with half brightness it goes off in 50% of the cases and full on in the other 50%.

When building with W=1, this fixes the following warnings:

------------------

From: Yi Yang <[email protected]>

[ Upstream commit 11e7f27b79757b6586645d87b95d5b78375ecdfc ]

There is a pid leakage:

It turns out that there is a race condition between disassociate_ctty() and tty_signal_session_leader(), which caused this leakage.

The pid memleak is triggered by the following race:
task[sshd] task[bash]
----------------------- -----------------------

                               disassociate_ctty();
                               spin_lock_irq(&current->sighand->siglock);
                               put_pid(current->signal->tty_old_pgrp);
                               current->signal->tty_old_pgrp = NULL;
                               tty = tty_kref_get(current->signal->tty);
                               spin_unlock_irq(&current->sighand->siglock);

tty_vhangup();
tty_lock(tty);
...
tty_signal_session_leader(); spin_lock_irq(&p->sighand->siglock);
...
if (tty->ctrl.pgrp) //tty->ctrl.pgrp is not NULL p->signal->tty_old_pgrp = get_pid(tty->ctrl.pgrp); //An extra get spin_unlock_irq(&p->sighand->siglock);
...

tty_unlock(tty);
                               if (tty) {
                                   tty_lock(tty);
                                   ...
                                   put_pid(tty->ctrl.pgrp);
                                   tty->ctrl.pgrp = NULL; //It's too late
                                   ...
                                   tty_unlock(tty);
                               }

The issue is believed to be introduced by commit c8bcd9c5be24 ("tty:
Fix ->session locking") who moves the unlock of siglock in disassociate_ctty() above "if (tty)", making a small window allowing tty_signal_session_leader() to kick in. It can be easily reproduced by adding a delay before "if (tty)" and at the entrance of tty_signal_session_leader().

To fix this issue, we move "put_pid(current->signal->tty_old_pgrp)" after "tty->ctrl.pgrp = NULL".

PATCH 125/191 perf tools: Get rid of evlist__add_on_all_cpus()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 60ea006f72512fd7c36f16cdbe91f4fc284f8115 ]

The cpu and thread maps are properly handled in libperf now. No need to do it in the perf tools anymore. Let's remove the logic.

PATCH 126/191 perf evlist: Avoid frequency mode for the dummy event

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ian Rogers <[email protected]>

[ Upstream commit f9cdeb58a9cf46c09b56f5f661ea8da24b6458c3 ]

Dummy events are created with an attribute where the period and freq are zero. evsel__config will then see the uninitialized values and initialize them in evsel__default_freq_period. As fequency mode is used by default the dummy event would be set to use frequency mode. However, this has no effect on the dummy event but does cause unnecessary timers/interrupts. Avoid this overhead by setting the period to 1 for dummy events.

evlist__add_aux_dummy calls evlist__add_dummy then sets freq=0 and period=1. This isn't necessary after this change and so the setting is removed.

Quoted 1 line

From Stephane:

The dummy event is not counting anything. It is used to collect mmap records and avoid a race condition during the synthesize mmap phase of perf record. As such, it should not cause any overhead during active profiling. Yet, it did. Because of a bug the dummy event was programmed as a sampling event in frequency mode. Events in that mode incur more kernel overheads because on timer tick, the kernel has to look at the number of samples for each event and potentially adjust the sampling period to achieve the desired frequency. The dummy event was therefore adding a frequency event to task and ctx contexts we may otherwise not have any, e.g.,

perf record -a -e cpu/event=0x3c,period=10000000/.

On each timer tick the perf_adjust_freq_unthr_context() is invoked and if ctx->nr_freq is non-zero, then the kernel will loop over ALL the events of the context looking for frequency mode ones. In doing, so it locks the context, and enable/disable the PMU of each hw event. If all the events of the context are in period mode, the kernel will have to traverse the list for nothing incurring overhead. The overhead is multiplied by a very large factor when this happens in a guest kernel. There is no need for the dummy event to be in frequency mode, it does not count anything and therefore should not cause extra overhead for no reason.

PATCH 127/191 usb: dwc2: fix possible NULL pointer dereference caused by driver concurrency

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jia-Ju Bai <[email protected]>

[ Upstream commit ef307bc6ef04e8c1ea843231db58e3afaafa9fa6 ]

In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue():

    spin_lock_irqsave(&hsotg->lock, flags);
    ...
	if (!urb->hcpriv) {
		dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n");
		goto out;
	}
    rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv
    ...
out:
    spin_unlock_irqrestore(&hsotg->lock, flags);

When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are concurrently executed, the NULL check of "urb->hcpriv" can be executed before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL pointer dereference.

This possible bug is found by an experimental static analysis tool developed by myself. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported, when my tool analyzes the source code of Linux 6.5.

To fix this possible bug, "urb->hcpriv = NULL" should be executed with holding the lock "hsotg->lock". After using this patch, my tool never reports the possible bug, with the kernelconfiguration allyesconfig for x86_64. Because I have no associated hardware, I cannot test the patch in runtime testing, and just verify it according to the code logic.

PATCH 131/191 tools: iio: iio_generic_buffer: Fix some integer type and calculation

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Chenyuan Mi <[email protected]>

[ Upstream commit 49d736313d0975ddeb156f4f59801da833f78b30 ]

In function size_from_channelarray(), the return value 'bytes' is defined as int type. However, the calcution of 'bytes' in this function is designed to use the unsigned int type. So it is necessary to change 'bytes' type to unsigned int to avoid integer overflow.

The size_from_channelarray() is called in main() function, its return value is directly multipled by 'buf_len' and then used as the malloc() parameter. The 'buf_len' is completely controllable by user, thus a multiplication overflow may occur here. This could allocate an unexpected small area.

PATCH 132/191 tools: iio: iio_generic_buffer ensure alignment

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Matti Vaittinen <[email protected]>

[ Upstream commit 2d3dff577dd0ea8fe9637a13822f7603c4a881c8 ]

The iio_generic_buffer can return garbage values when the total size of scan data is not a multiple of the largest element in the scan. This can be demonstrated by reading a scan, consisting, for example of one 4-byte and one 2-byte element, where the 4-byte element is first in the buffer.

The IIO generic buffer code does not take into account the last two padding bytes that are needed to ensure that the 4-byte data for next scan is correctly aligned.

Add the padding bytes required to align the next sample with the scan size.

PATCH 133/191 USB: usbip: fix stub_dev hub disconnect

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jonas Blixt <[email protected]>

[ Upstream commit 97475763484245916735a1aa9a3310a01d46b008 ]

If a hub is disconnected that has device(s) that's attached to the usbip layer the disconnect function might fail because it tries to release the port on an already disconnected hub.

Fixes 6080cd0e9239 ("staging: usbip: claim ports used by shared devices")

PATCH 134/191 dmaengine: pxa_dma: Remove an erroneous BUG_ON() in pxad_free_desc()

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <[email protected]>

[ Upstream commit 83c761f568733277ce1f7eb9dc9e890649c29a8c ]

If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then sw_desc->nb_desc is zero.
In such a case pxad_free_desc() is called and it will BUG_ON().

Remove this erroneous BUG_ON().

It is also useless, because if "sw_desc->nb_desc == 0", then, on the first iteration of the for loop, i is -1 and the loop will not be executed. (both i and sw_desc->nb_desc are 'int')

PATCH 139/191 modpost: fix tee MODULE_DEVICE_TABLE built on big-endian host

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <[email protected]>

[ Upstream commit 7f54e00e5842663c2cea501bbbdfa572c94348a3 ]

When MODULE_DEVICE_TABLE(tee, ) is built on a host with a different endianness from the target architecture, it results in an incorrect MODULE_ALIAS().

For example, see a case where drivers/char/hw_random/optee-rng.c is built as a module for ARM little-endian.

If you build it on a little-endian host, you will get the correct MODULE_ALIAS:

    $ grep MODULE_ALIAS drivers/char/hw_random/optee-rng.mod.c
    MODULE_ALIAS("tee:ab7a617c-b8e7-4d8f-8301-d09b61036b64*");

However, if you build it on a big-endian host, you will get a wrong MODULE_ALIAS:

    $ grep MODULE_ALIAS drivers/char/hw_random/optee-rng.mod.c
    MODULE_ALIAS("tee:646b0361-9bd0-0183-8f4d-e7b87c617aab*");

The same problem also occurs when you enable CONFIG_CPU_BIG_ENDIAN, and build it on a little-endian host.

This issue has been unnoticed because the ARM kernel is configured for little-endian by default, and most likely built on a little-endian host (cross-build on x86 or native-build on ARM).

The uuid field must not be reversed because uuid_t is an array of __u8.

Fixes 0fc1db9d1059 ("tee: add bus driver framework for TEE based devices")

PATCH 140/191 powerpc/40x: Remove stale PTE_ATOMIC_UPDATES macro

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christophe Leroy <[email protected]>

[ Upstream commit cc8ee288f484a2a59c01ccd4d8a417d6ed3466e3 ]

40x TLB handlers were reworked by commit 2c74e2586bb9 ("powerpc/40x:
Rework 40x PTE access and TLB miss") to not require PTE_ATOMIC_UPDATES anymore.

Then commit 4e1df545e2fa ("powerpc/pgtable: Drop PTE_ATOMIC_UPDATES") removed all code related to PTE_ATOMIC_UPDATES.

Remove left over PTE_ATOMIC_UPDATES macro.

PATCH 141/191 powerpc/xive: Fix endian conversion size

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Benjamin Gray <[email protected]>

[ Upstream commit ff7a60ab1e065257a0e467c13b519f4debcd7fcf ]

Sparse reports a size mismatch in the endian swap. The Opal implementation[1] passes the value as a __be64, and the receiving variable out_qsize is a u64, so the use of be32_to_cpu() appears to be an error.

PATCH 144/191 xhci: Loosen RPM as default policy to cover for AMD xHC 1.1

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Basavaraj Natikar <[email protected]>

[ Upstream commit 4baf1218150985ee3ab0a27220456a1f027ea0ac ]

The AMD USB host controller (1022:43f7) isn't going into PCI D3 by default without anything connected. This is because the policy that was introduced by commit a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devices") only covered 1.2 or later.

The 1.1 specification also has the same requirement as the 1.2 specification for D3 support. So expand the runtime PM as default policy to all AMD 1.1 devices as well.

PATCH 145/191 usb: host: xhci-plat: fix possible kernel oops while resuming

In reply to Greg Kroah-Hartman

5.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Sergey Shtylyov <[email protected]>

[ Upstream commit a5f928db59519a15e82ecba4ae3e7cbf5a44715a ]

If this driver enables the xHC clocks while resuming from sleep, it calls clk_prepare_enable() without checking for errors and blithely goes on to read/write the xHC's registers -- which, with the xHC not being clocked, at least on ARM32 usually causes an imprecise external abort exceptions which cause kernel oops. Currently, the chips for which the driver does the clock dance on suspend/resume seem to be the Broadcom STB SoCs, based on ARM32 CPUs, as it seems...

Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.
