2024-09-13blk-integrity: improved sg segment mappingKeith Busch
Make the integrity mapping more like data mapping, blk_rq_map_sg. Use the request to validate the segment count, and update the callers so they don't have to.

Always defining the field will make using it easier and less error prone in future patches. There shouldn't be any downside to this: the field fits in what would otherwise be a 2-byte hole, so we're not saving space by conditionally leaving it out.

2024-09-13mm: Define VM_DROPPABLE for powerpc/32Christophe Leroy
Commit 9651fcedf7b9 ("mm: add MAP_DROPPABLE for designating always lazily freeable mappings") only adds VM_DROPPABLE for 64 bits architectures. In order to also use the getrandom vDSO implementation on powerpc/32, use VM_ARCH_1 for VM_DROPPABLE on powerpc/32. This is possible because VM_ARCH_1 is used for VM_SAO on powerpc and VM_SAO is only for powerpc/64. It is used in combination with PROT_SAO in some parts of code that are restricted to CONFIG_PPC64 through #ifdefs, it is therefore possible to define VM_SAO for CONFIG_PPC64 only.

2024-09-13random: vDSO: add a __vdso_getrandom prototype for all architecturesXi Ruoyao
Without a prototype, we'll have to add a prototype for each architecture implementing vDSO getrandom. As most architectures will likely have the vDSO getrandom implemented in a near future, and we'd like to keep the declarations compatible everywhere (to ease the libc implementor work), we should really just have one copy of the prototype. This also is what's already done inside of include/vdso/gettime.h for those vDSO functions, so this continues that convention.

2024-09-13random: vDSO: minimize and simplify header includesChristophe Leroy
Depending on the architecture, building a 32-bit vDSO on a 64-bit kernel is problematic when some system headers are included. Minimise the amount of headers by moving needed items, such as __{get,put}_unaligned_t, into dedicated common headers and in general use more specific headers, similar to what was done in commit 8165b57bca21 ("linux/const.h: Extract common header for vDSO") and commit 8c59ab839f52 ("lib/vdso: Enable common headers"). On some architectures this results in missing PAGE_SIZE, as was described by commit 8b3843ae3634 ("vdso/datapage: Quick fix - use asm/page-def.h for ARM64"), so define this if necessary, in the same way as done prior by commit cffaefd15a8f ("vdso: Use CONFIG_PAGE_SHIFT in vdso/datapage.h"). Removing linux/time64.h leads to missing 'struct timespec64' in x86's asm/pvclock.h. Add a forward declaration of that struct in that file.

2024-09-13random: vDSO: move prototype of arch chacha function to vdso/getrandom.hJason A. Donenfeld
Having the prototype for __arch_chacha20_blocks_nostack in arch/x86/include/asm/vdso/getrandom.h meant that the prototype and large doc comment were cloned by every architecture, which has been causing unnecessary churn. Instead move it into include/vdso/getrandom.h, where it can be shared by all archs implementing it. As a side bonus, this then lets us use that prototype in the vdso_test_chacha self test, to ensure that it matches the source, and indeed doing so turned up some inconsistencies, which are rectified here.

2024-09-13locking/mutex: Define mutex_init() onceBart Van Assche
With CONFIG_PREEMPT_RT disabled __mutex_init() is a function. With CONFIG_PREEMPT_RT enabled, __mutex_init() is a macro. I assume this is why mutex_init() is defined twice as exactly the same macro. Prepare for introducing a new macro for mutex initialization by combining the two identical mutex_init() definitions into a single definition. This patch does not change any functionality because the C preprocessor expands macros when it encounters the macro name and not when a macro definition is encountered.

2024-09-13RDMA/mlx5: Use IB set_netdev and get_netdev functionsChiara Meiohas
The IB layer provides a common interface to store and get net devices associated to an IB device port (ib_device_set_netdev() and ib_device_get_netdev()). Previously, mlx5_ib stored and managed the associated net devices internally. Replace internal net device management in mlx5_ib with ib_device_set_netdev() when attaching/detaching a net device and ib_device_get_netdev() when retrieving the net device. Export ib_device_get_netdev(). For mlx5 representors/PFs/VFs and lag creation we replace the netdev assignments with the IB set/get netdev functions. In active-backup mode lag the active slave net device is stored in the lag itself. To assure the net device stored in a lag bond IB device is the active slave we implement the following: - mlx5_core: when modifying the slave of a bond we send the internal driver event MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE. - mlx5_ib: when catching the event call ib_device_set_netdev() This patch also ensures the correct IB events are sent in switchdev lag. While at it, when in multiport eswitch mode, only a single IB device is created for all ports. The said IB device will receive all netdev events of its VFs once loaded, thus to avoid overwriting the mapping of PF IB device to PF netdev, ignore NETDEV_REGISTER events if the ib device has already been mapped to a netdev.

2024-09-12io_uring: add IORING_REGISTER_COPY_BUFFERS methodJens Axboe
Buffers can get registered with io_uring, which allows to skip the repeated pin_pages, unpin/unref pages for each O_DIRECT operation. This reduces the overhead of O_DIRECT IO. However, registrering buffers can take some time. Normally this isn't an issue as it's done at initialization time (and hence less critical), but for cases where rings can be created and destroyed as part of an IO thread pool, registering the same buffers for multiple rings become a more time sensitive proposition. As an example, let's say an application has an IO memory pool of 500G. Initial registration takes: Got 500 huge pages (each 1024MB) Registered 500 pages in 409 msec or about 0.4 seconds. If we go higher to 900 1GB huge pages being registered: Registered 900 pages in 738 msec which is, as expected, a fully linear scaling. Rather than have each ring pin/map/register the same buffer pool, provide an io_uring_register(2) opcode to simply duplicate the buffers that are registered with another ring. Adding the same 900GB of registered buffers to the target ring can then be accomplished in: Copied 900 pages in 17 usec While timing differs a bit, this provides around a 25,000-40,000x speedup for this use case.

2024-09-12cxl: Move mailbox related bits to the same contextDave Jiang
Create a new 'struct cxl_mailbox' and move all mailbox related bits to it. This allows isolation of all CXL mailbox data in order to export some of the calls to external kernel callers and avoid exporting of CXL driver specific bits such has device states. The allocation of 'struct cxl_mailbox' is also split out with cxl_mailbox_init() so the mailbox can be created independently.

The flag of FW_ISO_CONTEXT_COMPLETIONS_CAUSE_IRQ directly causes hardIRQ request by 1394 OHCI hardware when the corresponding isochronous packet is transferred, however it is not so directly associated to hardIRQ processing itself. This commit renames the flag so that it relates to interrupt parameter of internal packet data.
