2024-11-15io_uring: add memory region registrationPavel Begunkov
Regions will serve multiple purposes. First, with it we can decouple ring/etc. object creation from registration / mapping of the memory they will be placed in. We already have hacks that allow to put both SQ and CQ into the same huge page, in the future we should be able to: region = create_region(io_ring); create_pbuf_ring(io_uring, region, offset=0); create_pbuf_ring(io_uring, region, offset=N); The second use case is efficiently passing parameters. The following patch enables back on top of regions IORING_ENTER_EXT_ARG_REG, which optimises wait arguments. It'll also be useful for request arguments replacing iovecs, msghdr, etc. pointers. Eventually it would also be handy for BPF as well if it comes to fruition.

2024-11-15io_uring: introduce concept of memory regionsPavel Begunkov
We've got a good number of mappings we share with the userspace, that includes the main rings, provided buffer rings, upcoming rings for zerocopy rx and more. All of them duplicate user argument parsing and some internal details as well (page pinnning, huge page optimisations, mmap'ing, etc.) Introduce a notion of regions. For userspace for now it's just a new structure called struct io_uring_region_desc which is supposed to parameterise all such mapping / queue creations. A region either represents a user provided chunk of memory, in which case the user_addr field should point to it, or a request for the kernel to allocate the memory, in which case the user would need to mmap it after using the offset returned in the mmap_offset field. With a uniform userspace API we can avoid additional boiler plate code and apply future optimisation to all of them at once. Internally, there is a new structure struct io_mapped_region holding all relevant runtime information and some helpers to work with it. This patch limits it to user provided regions.

2024-11-15workqueue: Reduce expensive locks for unbound workqueueWangyang Guo
For unbound workqueue, pwqs usually map to just a few pools. Most of the time, pwqs will be linked sequentially to wq->pwqs list by cpu index. Usually, consecutive CPUs have the same workqueue attribute (e.g. belong to the same NUMA node). This makes pwqs with the same pool cluster together in the pwq list. Only do lock/unlock if the pool has changed in flush_workqueue_prep_pwqs(). This reduces the number of expensive lock operations. The performance data shows this change boosts FIO by 65x in some cases when multiple concurrent threads write to xfs mount points with fsync. FIO Benchmark Details - FIO version: v3.35 - FIO Options: ioengine=libaio,iodepth=64,norandommap=1,rw=write, size=128M,bs=4k,fsync=1 - FIO Job Configs: 64 jobs in total writing to 4 mount points (ramdisks formatted as xfs file system). - Kernel Codebase: v6.12-rc5 - Test Platform: Xeon 8380 (2 sockets) Reviewed-by: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Wangyang Guo <wangyang.guo@intel.com> Reviewed-by: Lai Jiangshan <jiangshanlai@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2024-11-15efi/libstub: Parse builtin command line after bootloader provided oneArd Biesheuvel
When CONFIG_CMDLINE_EXTEND is set, the core kernel command line handling logic appends CONFIG_CMDLINE to the bootloader provided command line. The EFI stub does the opposite, and parses the builtin one first. The usual behavior of command line options is that the last one takes precedence if it appears multiple times, unless there is a meaningful way to combine them. In either case, parsing the builtin command line first while the core kernel does it in the opposite order is likely to produce inconsistent results in such cases. Therefore, switch the order in the stub to match the core kernel. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2024-11-15x86/efi: Apply EFI Memory Attributes after kexecNicolas Saenz Julienne

2024-11-15crypto: arm/crct10dif - Implement plain NEON variantArd Biesheuvel
The CRC-T10DIF algorithm produces a 16-bit CRC, and this is reflected in the folding coefficients, which are also only 16 bits wide. This means that the polynomial multiplications involving these coefficients can be performed using 8-bit long polynomial multiplication (8x8 -> 16) in only a few steps, and this is an instruction that is part of the base NEON ISA, which is all most real ARMv7 cores implement. (The 64-bit PMULL instruction is part of the crypto extensions, which are only implemented by 64-bit cores) The final reduction is a bit more involved, but we can delegate that to the generic CRC-T10DIF implementation after folding the entire input into a 16 byte vector. This results in a speedup of around 6.6x on Cortex-A72 running in 32-bit mode. On Cortex-A8 (BeagleBone White), the results are substantially better than that, but not sufficiently reproducible (with tcrypt) to quote a number here.

2024-11-15crypto: arm64/crct10dif - Use faster 16x64 bit polynomial multiplyArd Biesheuvel
The CRC-T10DIF implementation for arm64 has a version that uses 8x8 polynomial multiplication, for cores that lack the crypto extensions, which cover the 64x64 polynomial multiplication instruction that the algorithm was built around. This fallback version rather naively adopted the 64x64 polynomial multiplication algorithm that I ported from ARM for the GHASH driver, which needs 8 PMULL8 instructions to implement one PMULL64. This is reasonable, given that each 8-bit vector element needs to be multiplied with each element in the other vector, producing 8 vectors with partial results that need to be combined to yield the correct result. However, most PMULL64 invocations in the CRC-T10DIF code involve multiplication by a pair of 16-bit folding coefficients, and so all the partial results from higher order bytes will be zero, and there is no need to calculate them to begin with. Then, the CRC-T10DIF algorithm always XORs the output values of the PMULL64 instructions being issued in pairs, and so there is no need to faithfully implement each individual PMULL64 instruction, as long as XORing the results pairwise produces the expected result. Implementing these improvements results in a speedup of 3.3x on low-end platforms such as Raspberry Pi 4 (Cortex-A72) Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2024-11-15efi/memattr: Ignore table if the size is clearly bogusArd Biesheuvel
There are reports [0] of cases where a corrupt EFI Memory Attributes Table leads to out of memory issues at boot because the descriptor size and entry count in the table header are still used to reserve the entire table in memory, even though the resulting region is gigabytes in size. Given that the EFI Memory Attributes Table is supposed to carry up to 3 entries for each EfiRuntimeServicesCode region in the EFI memory map, and given that there is no reason for the descriptor size used in the table to exceed the one used in the EFI memory map, 3x the size of the entire EFI memory map is a reasonable upper bound for the size of this table. This means that sizes exceeding that are highly likely to be based on corrupted data, and the table should just be ignored instead.

2024-11-15netfilter: nf_dup4: Convert nf_dup_ipv4_route() to dscp_t.Guillaume Nault
Use ip4h_dscp() instead of reading iph->tos directly. ip4h_dscp() returns a dscp_t value which is temporarily converted back to __u8 with inet_dscp_to_dsfield(). When converting ->flowi4_tos to dscp_t in the future, we'll only have to remove that inet_dscp_to_dsfield() call.

2024-11-15efi/zboot: Fix outdated comment about using LoadImage/StartImageArd Biesheuvel
EFI zboot no longer uses LoadImage/StartImage, but subsumes the arch code to load and start the bare metal image directly. Fix the Kconfig description accordingly. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2024-11-15efi/libstub: Free correct pointer on failureArd Biesheuvel
cmdline_ptr is an out parameter, which is not allocated by the function itself, and likely points into the caller's stack. cmdline refers to the pool allocation that should be freed when cleaning up after a failure, so pass this instead to free_pool().

2024-11-15ovl: convert ovl_real_fdget() callers to ovl_real_file()Amir Goldstein
Stop using struct fd to return a real file from ovl_real_fdget(), because we no longer return a temporary file object and the callers always get a borrowed file reference. Rename the helper to ovl_real_file(), return a borrowed reference of the real file that is referenced from the overlayfs file or an error. Signed-off-by: Amir Goldstein <amir73il@gmail.com>
