2024-09-12net: apple: bmac: Use IRQF_NO_AUTOEN flag in request_irq()Jinjie Ruan
disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

Guillaume Nault says: ==================== bareudp: Pull inner IP header on xmit/recv. Bareudp accesses the inner IP header in its xmit and recv paths. However it doesn't ensure that this header is part of skb->head. Both vxlan and geneve have received fixes for similar problems in the past.

2024-09-12bareudp: Pull inner IP header on xmit.Guillaume Nault
Both bareudp_xmit_skb() and bareudp6_xmit_skb() read their skb's inner IP header to get its ECN value (with ip_tunnel_ecn_encap()). Therefore we need to ensure that the inner IP header is part of the skb's linear data.

Bareudp reads the inner IP header to get the ECN value. Therefore, it needs to ensure that it's part of the skb's linear data.

2024-09-12mm: avoid leaving partial pfn mappings around in error caseLinus Torvalds
As Jann points out, PFN mappings are special, because unlike normal memory mappings, there is no lifetime information associated with the mapping - it is just a raw mapping of PFNs with no reference counting of a 'struct page'. That's all very much intentional, but it does mean that it's easy to mess up the cleanup in case of errors. Yes, a failed mmap() will always eventually clean up any partial mappings, but without any explicit lifetime in the page table mapping itself, it's very easy to do the error handling in the wrong order. In particular, it's easy to mistakenly free the physical backing store before the page tables are actually cleaned up and (temporarily) have stale dangling PTE entries. To make this situation less error-prone, just make sure that any partial pfn mapping is torn down early, before any other error handling.

2024-09-12drm/xe: prevent potential UAF in pf_provision_vf_ggtt()Matthew Auld
The node ptr can point to an already freed ptr, if we hit the path with an already allocated node. We later dereference that pointer with: xe_gt_assert(gt, !xe_ggtt_node_allocated(node)); which is a potential UAF. Fix this by not stashing the ptr for node. Also since it is likely a bad idea to leave config->ggtt_region pointing to a stale ptr, also set that to NULL by calling pf_release_vf_config_ggtt() instead of pf_release_ggtt().

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.

2024-09-12ALSA: memalloc: Use proper DMA mapping API for x86 S/G buffer allocationsTakashi Iwai
The fallback S/G buffer allocation for x86 used the addresses deduced from the page allocations blindly. It broke the allocations on IOMMU and made us to work around with a hackish DMA ops check. For cleaning up those messes, this patch switches to the proper DMA mapping API usages with the standard sg-table instead. By introducing the sg-table, the address table isn't needed, but for keeping the original allocation sizes for freeing, replace it with the array keeping the number of pages. The get_addr callback is changed to use the existing one for non-contiguous buffers. (Also it's the reason sg_table is put at the beginning of struct snd_dma_sg_fallback.) And finally, the hackish workaround that checks the DMA ops is dropped now. Link: https://patch.msgid.link/20240912155227.4078-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

2024-09-12kunit: tool: Build compile_commands.jsonBrendan Jackman
compile_commands.json is used by clangd[1] to provide code navigation and completion functionality to editors. See [2] for an example configuration that includes this functionality for VSCode. It can currently be built manually when using kunit.py, by running: ./scripts/clang-tools/gen_compile_commands.py -d .kunit With this change however, it's built automatically so you don't need to manually keep it up to date. Unlike the manual approach, having make build the compile_commands.json means that it appears in the build output tree instead of at the root of the source tree, so you'll need to add --compile-commands-dir=.kunit to your clangd args for it to be found. This might turn out to be pretty annoying, I'm not sure yet. If so maybe we can later add some hackery to kunit.py to work around it.
