2024-12-18drm/amdgpu: don't access invalid schedPierre-Eric Pelloux-Prayer
Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()") accessing job->base.sched can produce unexpected results as the initialisation of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the memset. This commit fixes an issue when a CS would fail validation and would be rejected after job->num_ibs is incremented. In this case, amdgpu_ib_free(ring->adev, ...) will be called, which would crash the machine because the ring value is bogus. To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this because the device is actually not used in this function. The next commit will remove the ring argument completely.

2024-12-18thermal/thresholds: Fix boundaries and detection routineDaniel Lezcano
The current implementation does not work if the thermal zone is interrupt driven only. The boundaries are not correctly checked and computed as it happens only when the temperature is increasing or decreasing. The problem arises because the routine to detect when we cross a threshold is correlated with the computation of the boundaries. We assume we have to recompute the boundaries when a threshold is crossed but actually we should do that even if the it is not the case. Mixing the boundaries computation and the threshold detection for the sake of optimizing the routine is much more complex as it appears intuitively and prone to errors. This fix separates the boundaries computation and the threshold crossing detection into different routines. The result is a code much more simple to understand, thus easier to maintain. The drawback is we browse the thresholds list several time but we can consider that as neglictible because that happens when the temperature is updated. There are certainly some aeras to improve in the temperature update routine but it would be not adequate as this change aims to fix the thresholds for v6.13.

2024-12-18can: m_can: fix missed interrupts with m_can_pciMatthias Schiffer
The interrupt line of PCI devices is interpreted as edge-triggered, however the interrupt signal of the m_can controller integrated in Intel Elkhart Lake CPUs appears to be generated level-triggered. Consider the following sequence of events: - IR register is read, interrupt X is set - A new interrupt Y is triggered in the m_can controller - IR register is written to acknowledge interrupt X. Y remains set in IR As at no point in this sequence no interrupt flag is set in IR, the m_can interrupt line will never become deasserted, and no edge will ever be observed to trigger another run of the ISR. This was observed to result in the TX queue of the EHL m_can to get stuck under high load, because frames were queued to the hardware in m_can_start_xmit(), but m_can_finish_tx() was never run to account for their successful transmission. On an Elkhart Lake based board with the two CAN interfaces connected to each other, the following script can reproduce the issue: ip link set can0 up type can bitrate 1000000 ip link set can1 up type can bitrate 1000000 cangen can0 -g 2 -I 000 -L 8 & cangen can0 -g 2 -I 001 -L 8 & cangen can0 -g 2 -I 002 -L 8 & cangen can0 -g 2 -I 003 -L 8 & cangen can0 -g 2 -I 004 -L 8 & cangen can0 -g 2 -I 005 -L 8 & cangen can0 -g 2 -I 006 -L 8 & cangen can0 -g 2 -I 007 -L 8 & cangen can1 -g 2 -I 100 -L 8 & cangen can1 -g 2 -I 101 -L 8 & cangen can1 -g 2 -I 102 -L 8 & cangen can1 -g 2 -I 103 -L 8 & cangen can1 -g 2 -I 104 -L 8 & cangen can1 -g 2 -I 105 -L 8 & cangen can1 -g 2 -I 106 -L 8 & cangen can1 -g 2 -I 107 -L 8 & stress-ng --matrix 0 & To fix the issue, repeatedly read and acknowledge interrupts at the start of the ISR until no interrupt flags are set, so the next incoming interrupt will also result in an edge on the interrupt line. While we have received a report that even with this patch, the TX queue can become stuck under certain (currently unknown) circumstances on the Elkhart Lake, this patch completely fixes the issue with the above reproducer, and it is unclear whether the remaining issue has a similar cause at all.

2024-12-18can: m_can: set init flag earlier in probeMatthias Schiffer
While an m_can controller usually already has the init flag from a hardware reset, no such reset happens on the integrated m_can_pci of the Intel Elkhart Lake. If the CAN controller is found in an active state, m_can_dev_setup() would fail because m_can_niso_supported() calls m_can_cccr_update_bits(), which refuses to modify any other configuration bits when CCCR_INIT is not set. To avoid this issue, set CCCR_INIT before attempting to modify any other configuration flags.

2024-12-17idpf: trigger SW interrupt when exiting wb_on_itr modeJoshua Hay
There is a race condition between exiting wb_on_itr and completion write backs. For example, we are in wb_on_itr mode and a Tx completion is generated by HW, ready to be written back, as we are re-enabling interrupts: HW SW | | | | idpf_tx_splitq_clean_all | | napi_complete_done | | | tx_completion_wb | idpf_vport_intr_update_itr_ena_irq That tx_completion_wb happens before the vector is fully re-enabled. Continuing with this example, it is a UDP stream and the tx_completion_wb is the last one in the flow (there are no rx packets). Because the HW generated the completion before the interrupt is fully enabled, the HW will not fire the interrupt once the timer expires and the write back will not happen. NAPI poll won't be called. We have indicated we're back in interrupt mode but nothing else will trigger the interrupt. Therefore, the completion goes unprocessed, triggering a Tx timeout. To mitigate this, fire a SW triggered interrupt upon exiting wb_on_itr. This interrupt will catch the rogue completion and avoid the timeout. Add logic to set the appropriate bits in the vector's dyn_ctl register.

2024-12-17clk: thead: Fix TH1520 emmc and shdci clock rateMaksim Kiselev
In accordance with LicheePi 4A BSP the clock that comes to emmc/sdhci is 198Mhz which is got through frequency division of source clock VIDEO PLL by 4 [1]. But now the AP_SUBSYS driver sets the CLK EMMC SDIO to the same frequency as the VIDEO PLL, equal to 792 MHz. This causes emmc/sdhci to work 4 times slower. Let's fix this issue by adding fixed factor clock that divides VIDEO PLL by 4 for emmc/sdhci.

2024-12-17pinctrl: mcp23s08: Fix sleeping in atomic context due to regmap lockingEvgenii Shatokhin
If a device uses MCP23xxx IO expander to receive IRQs, the following bug can happen: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, ... preempt_count: 1, expected: 0 ... Call Trace: ... __might_resched+0x104/0x10e __might_sleep+0x3e/0x62 mutex_lock+0x20/0x4c regmap_lock_mutex+0x10/0x18 regmap_update_bits_base+0x2c/0x66 mcp23s08_irq_set_type+0x1ae/0x1d6 __irq_set_trigger+0x56/0x172 __setup_irq+0x1e6/0x646 request_threaded_irq+0xb6/0x160 ... We observed the problem while experimenting with a touchscreen driver which used MCP23017 IO expander (I2C). The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection from concurrent accesses, which is the default for regmaps without .fast_io, .disable_locking, etc. mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latter locks the mutex. However, __setup_irq() locks desc->lock spinlock before calling these functions. As a result, the system tries to lock the mutex whole holding the spinlock. It seems, the internal regmap locks are not needed in this driver at all. mcp->lock seems to protect the regmap from concurrent accesses already, except, probably, in mcp_pinconf_get/set. mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under chip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes mcp->lock and enables regmap caching, so that the potentially slow I2C accesses are deferred until chip_bus_unlock(). The accesses to the regmap from mcp23s08_probe_one() do not need additional locking. In all remaining places where the regmap is accessed, except mcp_pinconf_get/set(), the driver already takes mcp->lock. This patch adds locking in mcp_pinconf_get/set() and disables internal locking in the regmap config. Among other things, it fixes the sleeping in atomic context described above.

2024-12-17net: ethernet: oa_tc6: fix tx skb race condition between reference pointersParthiban Veerasooran
There are two skb pointers to manage tx skb's enqueued from n/w stack. waiting_tx_skb pointer points to the tx skb which needs to be processed and ongoing_tx_skb pointer points to the tx skb which is being processed. SPI thread prepares the tx data chunks from the tx skb pointed by the ongoing_tx_skb pointer. When the tx skb pointed by the ongoing_tx_skb is processed, the tx skb pointed by the waiting_tx_skb is assigned to ongoing_tx_skb and the waiting_tx_skb pointer is assigned with NULL. Whenever there is a new tx skb from n/w stack, it will be assigned to waiting_tx_skb pointer if it is NULL. Enqueuing and processing of a tx skb handled in two different threads. Consider a scenario where the SPI thread processed an ongoing_tx_skb and it moves next tx skb from waiting_tx_skb pointer to ongoing_tx_skb pointer without doing any NULL check. At this time, if the waiting_tx_skb pointer is NULL then ongoing_tx_skb pointer is also assigned with NULL. After that, if a new tx skb is assigned to waiting_tx_skb pointer by the n/w stack and there is a chance to overwrite the tx skb pointer with NULL in the SPI thread. Finally one of the tx skb will be left as unhandled, resulting packet missing and memory leak. - Consider the below scenario where the TXC reported from the previous transfer is 10 and ongoing_tx_skb holds an tx ethernet frame which can be transported in 20 TXCs and waiting_tx_skb is still NULL. tx_credits = 10; /* 21 are filled in the previous transfer */ ongoing_tx_skb = 20; waiting_tx_skb = NULL; /* Still NULL */ - So, (tc6->ongoing_tx_skb || tc6->waiting_tx_skb) becomes true. - After oa_tc6_prepare_spi_tx_buf_for_tx_skbs() ongoing_tx_skb = 10; waiting_tx_skb = NULL; /* Still NULL */ - Perform SPI transfer. - Process SPI rx buffer to get the TXC from footers. - Now let's assume previously filled 21 TXCs are freed so we are good to transport the next remaining 10 tx chunks from ongoing_tx_skb. tx_credits = 21; ongoing_tx_skb = 10; waiting_tx_skb = NULL; - So, (tc6->ongoing_tx_skb || tc6->waiting_tx_skb) becomes true again. - In the oa_tc6_prepare_spi_tx_buf_for_tx_skbs() ongoing_tx_skb = NULL; waiting_tx_skb = NULL; - Now the below bad case might happen, Thread1 (oa_tc6_start_xmit) Thread2 (oa_tc6_spi_thread_handler) --------------------------- ----------------------------------- - if waiting_tx_skb is NULL - if ongoing_tx_skb is NULL - ongoing_tx_skb = waiting_tx_skb - waiting_tx_skb = skb - waiting_tx_skb = NULL ... - ongoing_tx_skb = NULL - if waiting_tx_skb is NULL - waiting_tx_skb = skb To overcome the above issue, protect the moving of tx skb reference from waiting_tx_skb pointer to ongoing_tx_skb pointer and assigning new tx skb to waiting_tx_skb pointer, so that the other thread can't access the waiting_tx_skb pointer until the current thread completes moving the tx skb reference safely.

2024-12-17net: ethernet: oa_tc6: fix infinite loop error when tx credits becomes 0Parthiban Veerasooran
SPI thread wakes up to perform SPI transfer whenever there is an TX skb from n/w stack or interrupt from MAC-PHY. Ethernet frame from TX skb is transferred based on the availability tx credits in the MAC-PHY which is reported from the previous SPI transfer. Sometimes there is a possibility that TX skb is available to transmit but there is no tx credits from MAC-PHY. In this case, there will not be any SPI transfer but the thread will be running in an endless loop until tx credits available again. So checking the availability of tx credits along with TX skb will prevent the above infinite loop. When the tx credits available again that will be notified through interrupt which will trigger the SPI transfer to get the available tx credits.

Active busyness of an engine is calculated using gt timestamp and the context switch in time. While capturing the gt timestamp, it's possible that the context switches out. This race could result in an active busyness value that is greater than the actual context runtime value by a small amount. This leads to a negative delta and throws off busyness calculations for the user. If a subsequent count is smaller than the previous one, just return the previous one, since we expect the busyness to catch up.

Make it optional again to fix use of older DT. ti,ads1119 - Use a fixed size for the channel data rather than an integer, bringing the code inline with the advertised 16 bit channel size and avoiding userspace misinterpreting the data. ti,ads124s08 - Use _cansleep gpio calls as no reason to prevent sleeping and it was stopping a new board design working (trivial fix). ti,ads1298 - Add a check on failure of devm_kasprintf() * tag 'iio-fixes-for-6.13a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (27 commits) iio: adc: ti-ads1119: fix sample size in scan struct for triggered buffer iio: temperature: tmp006: fix information leak in triggered buffer iio: inkern: call iio_device_put() only on mapped devices iio: adc: ad9467: Fix the "don't allow reading vref if not available" case iio: adc: at91: call input_free_device() on allocated iio_dev iio: adc: ad7173: fix using shared static info struct iio: adc: ti-ads124s08: Use gpiod_set_value_cansleep() iio: adc: ti-ads1119: fix information leak in triggered buffer iio: pressure: zpa2326: fix information leak in triggered buffer iio: adc: rockchip_saradc: fix information leak in triggered buffer iio: imu: kmx61: fix information leak in triggered buffer iio: light: vcnl4035: fix information leak in triggered buffer iio: light: bh1745: fix information leak in triggered buffer iio: adc: ti-ads8688: fix information leak in triggered buffer iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered buffer iio: test: Fix GTS test config dt-bindings: iio: st-sensors: Re-add IIS2MDC magnetometer iio: adc: ti-ads1298: Add NULL check in ads1298_init iio: adc: stm32-dfsdm: handle label as an optional property iio: adc: ad4695: fix buffered read, single sample timings ...

2024-12-16RDMA/bnxt_re: Fix setting mandatory attributes for modify_qpDamodharam Ammepalli
Firmware expects "min_rnr_timer" as a mandatory attribute in MODIFY_QP command during the RTR-RTS transition. This needs to be enforced by the driver which is missing while setting bnxt_set_mandatory_attributes that sends these flags as part of modify_qp optimization.
