2025-06-26io_uring/kbuf: flag partial buffer mappingsJens Axboe
A previous commit aborted mapping more for a non-incremental ring for bundle peeking, but depending on where in the process this peeking happened, it would not necessarily prevent a retry by the user. That can create gaps in the received/read data. Add struct buf_sel_arg->partial_map, which can pass this information back. The networking side can then map that to internal state and use it to gate retry as well. Since this necessitates a new flag, change io_sr_msg->retry to a retry_flags member, and store both the retry and partial map condition in there.

2025-06-26NFSv4/flexfiles: Fix handling of NFS level errors in I/OTrond Myklebust
Allow the flexfiles error handling to recognise NFS level errors (as opposed to RPC level errors) and handle them separately. The main motivator is the NFSERR_PERM errors that get returned if the NFS client connects to the data server through a port number that is lower than 1024. In that case, the client should disconnect and retry a READ on a different data server, or it should retry a WRITE after reconnecting.

2025-06-26cifs: Fix reading into an ITER_FOLIOQ from the smbdirect codeDavid Howells
When performing a file read from RDMA, smbd_recv() prints an "Invalid msg type 4" error and fails the I/O. This is due to the switch-statement there not handling the ITER_FOLIOQ handed down from netfslib. Fix this by collapsing smbd_recv_buf() and smbd_recv_page() into smbd_recv() and just using copy_to_iter() instead of memcpy(). This future-proofs the function too, in case more ITER_* types are added.

2025-06-26cifs: Fix the smbd_response slab to allow usercopyDavid Howells
The handling of received data in the smbdirect client code involves using copy_to_iter() to copy data from the smbd_reponse struct's packet trailer to a folioq buffer provided by netfslib that encapsulates a chunk of pagecache. If, however, CONFIG_HARDENED_USERCOPY=y, this will result in the checks then performed in copy_to_iter() oopsing with something like the following: CIFS: Attempting to mount //172.31.9.1/test CIFS: VFS: RDMA transport established usercopy: Kernel memory exposure attempt detected from SLUB object 'smbd_response_0000000091e24ea1' (offset 81, size 63)! ------------[ cut here ]------------ kernel BUG at mm/usercopy.c:102! ...

Fix this by passing parameters to kmem_slab_create() to indicate that copy_to_iter() is permitted from the packet region of the smbd_response slab objects, less the header space.

2025-06-26ice: default to TIME_REF instead of TXCO on E825-CJacob Keller
The driver currently defaults to the internal oscillator as the clock source for E825-C hardware. While this clock source is labeled TCXO, indicating a temperature compensated oscillator, this is only true for some board designs. Many board designs have a less capable oscillator. The E825-C hardware may also have its clock source set to the TIME_REF pin. This pin is connected to the DPLL and is often a more stable clock source. The choice of the internal oscillator is not suitable for all systems, especially those which want to enable SyncE support. There is currently no interface available for users to configure the clock source. Other variants of the E82x board have the clock source configured in the NVM, but E825-C lacks this capability, so different board designs cannot select a different default clock via firmware. In most setups, the TIME_REF is a suitable default clock source. Additionally, we now fall back to the internal oscillator automatically if the TIME_REF clock source cannot be locked. Change the default clock source for E825-C to TIME_REF. Note that the driver logs a dev_dbg message upon configuring the TSPLL which includes the clock source and frequency. This can be enabled to confirm which clock source is in use. Longterm a proper interface to dynamically introspect and change the clock source will be designed (perhaps some extension of the DPLL subsystem?)

2025-06-26eth: fbnic: rename fbnic_fw_clear_cmpl to fbnic_mbx_clear_cmplJakub Kicinski
fbnic_fw_clear_cmpl() does the inverse of fbnic_mbx_set_cmpl(). It removes the completion from the mailbox table. It also calls fbnic_mbx_set_cmpl_slot() internally. It should have fbnic_mbx prefix, not fbnic_fw. I'm not very clear on what the distinction is between the two prefixes but the matching "set" and "clear" functions should use the same prefix. While at it move the "clear" function closer to the "set".

2025-06-26drm/xe/guc: Explicitly exit CT safe mode on unwindMichal Wajdeczko
During driver probe we might be briefly using CT safe mode, which is based on a delayed work, but usually we are able to stop this once we have IRQ fully operational. However, if we abort the probe quite early then during unwind we might try to destroy the workqueue while there is still a pending delayed work that attempts to restart itself which triggers a WARN.

For backwards compatibility, the "impossible" modes that claim to have a delay on the PCB are still accepted, but trigger a warning message. As Andrew suggested, I have also added a checkpatch check that requires a comment for any RGMII mode that is not "rgmii-id". No Device Trees are updated to avoid the warning for now, to give other projects syncing the Linux Device Trees some time to fix their drivers as well. I intend to submit an equivalent change for U-Boot's am65-cpsw-nuss driver as soon as the changes are accepted for Linux.

Historically, the RGMII PHY modes specified in Device Trees have been used inconsistently, often referring to the usage of delays on the PHY side rather than describing the board; many drivers still implement this incorrectly.

2025-06-26LoongArch: Reserve the EFI memory map regionMing Wang
The EFI memory map at 'boot_memmap' is crucial for kdump to understand the primary kernel's memory layout. This memory region, typically part of EFI Boot Services (BS) data, can be overwritten after ExitBootServices if not explicitly preserved by the kernel. This commit addresses this by: 1. Calling memblock_reserve() to reserve the entire physical region occupied by the EFI memory map (header + descriptors). This prevents the primary kernel from reallocating and corrupting this area. 2. Setting the EFI_PRESERVE_BS_REGIONS flag in efi.flags. This indicates that efforts have been made to preserve critical BS code/data regions which can be useful for other kernel subsystems or debugging. These changes ensure the original EFI memory map data remains intact, improving kdump reliability and potentially aiding other EFI-related functionalities that might rely on preserved BS code/data.

2025-06-26LoongArch: Replace __ASSEMBLY__ with __ASSEMBLER__ in headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This is bad since macros starting with two underscores are names that are reserved by the C language. It can also be very confusing for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with one comment tweaked manually in the arch/loongarch/include/asm/cpu.h file (it was missing the trailing underscores).

2025-06-26perf/aux: Fix pending disable flow when the AUX ring buffer overrunsLeo Yan
If an AUX event overruns, the event core layer intends to disable the event by setting the 'pending_disable' flag. Unfortunately, the event is not actually disabled afterwards. In commit: ca6c21327c6a ("perf: Fix missing SIGTRAPs") the 'pending_disable' flag was changed to a boolean. However, the AUX event code was not updated accordingly. The flag ends up holding a CPU number. If this number is zero, the flag is taken as false and the IRQ work is never triggered. Later, with commit: 2b84def990d3 ("perf: Split __perf_pending_irq() out of perf_pending_irq()") a new IRQ work 'pending_disable_irq' was introduced to handle event disabling. The AUX event path was not updated to kick off the work queue. To fix this bug, when an AUX ring buffer overrun is detected, call perf_event_disable_inatomic() to initiate the pending disable flow. Also update the outdated comment for setting the flag, to reflect the boolean values (0 or 1).
