2024-09-09ASoC: tlv320aic31xx: Add support for loading filter coefficientsRomain Gantois
The TLV320DAC3100 Audio DAC has 25 built-in digital audio processing blocks (PRBs). Each of these PRBs has a static filter structure with programmable coefficients. Once a PRB is selected for use by the DAC, its filter coefficients can be configured via a dedicated set of registers. Define a new optional firmware which can be loaded by the TLV320DAC driver. This firmware describes a full set of filter coefficients for all blocks used by the various PRBs. The firmware's binary format is heavily inspired by the one used in the peb2466 driver. It includes a version marker to allow for potential evolutions of the format. Note that adaptive filtering is not supported i.e. filter coefficients are loaded once before power-on and then cannot be changed while the DAC is powered. This is why only page A coefficients are modified. Page B coefficients are only used for adaptive filtering.

2024-09-09dma-buf: heaps: Fix off-by-one in CMA heap fault handlerT.J. Mercier
Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping.

2024-09-09net: ethernet: fs_enet: phylink conversionMaxime Chevallier
fs_enet is a quite old but still used Ethernet driver found on some NXP devices. It has support for 10/100 Mbps ethernet, with half and full duplex. Some variants of it can use RMII, while other integrations are MII-only. Add phylink support, thus removing custom fixed-link hanldling. This also allows removing some internal flags such as the use_rmii flag.

2024-09-09net: ethernet: fs_enet: only protect the .restart() call in .adjust_linkMaxime Chevallier
When .adjust_link() gets called, it runs in thread context, with the phydev->lock held. We only need to protect the fep->fecp/fccp/sccp register that are accessed within the .restart() function from concurrent access from the interrupts. These registers are being protected by the fep->lock spinlock, so we can move the spinlock protection around the .restart() call instead of the entire adjust_link() call. By doing so, we can simplify further the .adjust_link() callback and avoid the intermediate helper.

2024-09-09can: rockchip_canfd: fix return type of rkcanfd_start_xmit()Nathan Chancellor
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A warning in clang aims to catch these at compile time, which reveals: drivers/net/can/rockchip/rockchip_canfd-core.c:770:20: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict] 770 | .ndo_start_xmit = rkcanfd_start_xmit, | ^~~~~~~~~~~~~~~~~~ ->ndo_start_xmit() in 'struct net_device_ops' expects a return type of 'netdev_tx_t', not 'int' (although the types are ABI compatible). Adjust the return type of rkcanfd_start_xmit() to match the prototype's to resolve the warning.

2024-09-08io_uring/eventfd: move refs to refcount_tJens Axboe
atomic_t for the struct io_ev_fd references and there are no issues with it. While the ref getting and putting for the eventfd code is somewhat performance critical for cases where eventfd signaling is used (news flash, you should not...), it probably doesn't warrant using an atomic_t for this. Let's just move to it to refcount_t to get the added protection of over/underflows.

2024-09-08ptp/ioctl: support MONOTONIC{,_RAW} timestamps for PTP_SYS_OFFSET_EXTENDEDMahesh Bandewar
The ability to read the PHC (Physical Hardware Clock) alongside multiple system clocks is currently dependent on the specific hardware architecture. This limitation restricts the use of PTP_SYS_OFFSET_PRECISE to certain hardware configurations. The generic soultion which would work across all architectures is to read the PHC along with the latency to perform PHC-read as offered by PTP_SYS_OFFSET_EXTENDED which provides pre and post timestamps. However, these timestamps are currently limited to the CLOCK_REALTIME timebase. Since CLOCK_REALTIME is affected by NTP (or similar time synchronization services), it can experience significant jumps forward or backward. This hinders the precise latency measurements that PTP_SYS_OFFSET_EXTENDED is designed to provide. This problem could be addressed by supporting MONOTONIC_RAW timestamps within PTP_SYS_OFFSET_EXTENDED. Unlike CLOCK_REALTIME or CLOCK_MONOTONIC, the MONOTONIC_RAW timebase is unaffected by NTP adjustments. This enhancement can be implemented by utilizing one of the three reserved words within the PTP_SYS_OFFSET_EXTENDED struct to pass the clock-id for timestamps. The current behavior aligns with clock-id for CLOCK_REALTIME timebase (value of 0), ensuring backward compatibility of the UAPI.
