2023-04-17x86/hyperv: Exclude lazy TLB mode CPUs from enlightened TLB flushesMichael Kelley
In the case where page tables are not freed, native_flush_tlb_multi() does not do a remote TLB flush on CPUs in lazy TLB mode because the CPU will flush itself at the next context switch. By comparison, the Hyper-V enlightened TLB flush does not exclude CPUs in lazy TLB mode and so performs unnecessary flushes. If we're not freeing page tables, add logic to test for lazy TLB mode when adding CPUs to the input argument to the Hyper-V TLB flush hypercall. Exclude lazy TLB mode CPUs so the behavior matches native_flush_tlb_multi() and the unnecessary flushes are avoided. Handle both the <=64 vCPU case and the _ex case for >64 vCPUs.

2023-04-17x86/hyperv: Add callback filter to cpumask_to_vpset()Michael Kelley
When copying CPUs from a Linux cpumask to a Hyper-V VPset, cpumask_to_vpset() currently has a "_noself" variant that doesn't copy the current CPU to the VPset. Generalize this variant by replacing it with a "_skip" variant having a callback function that is invoked for each CPU to decide if that CPU should be copied. Update the one caller of cpumask_to_vpset_noself() to use the new "_skip" variant instead. No functional change.

2023-04-17PCI: hv: Enable PCI pass-thru devices in Confidential VMsMichael Kelley
For PCI pass-thru devices in a Confidential VM, Hyper-V requires that PCI config space be accessed via hypercalls. In normal VMs, config space accesses are trapped to the Hyper-V host and emulated. But in a confidential VM, the host can't access guest memory to decode the instruction for emulation, so an explicit hypercall must be used. Add functions to make the new MMIO read and MMIO write hypercalls. Update the PCI config space access functions to use the hypercalls when such use is indicated by Hyper-V flags. Also, set the flag to allow the Hyper-V PCI driver to be loaded and used in a Confidential VM (a.k.a., "Isolation VM"). The driver has previously been hardened against a malicious Hyper-V host[1].

2023-04-17Drivers: hv: Don't remap addresses that are above shared_gpa_boundaryMichael Kelley
With the vTOM bit now treated as a protection flag and not part of the physical address, avoid remapping physical addresses with vTOM set since technically such addresses aren't valid. Use ioremap_cache() instead of memremap() to ensure that the mapping provides decrypted access, which will correctly set the vTOM bit as a protection flag. While this change is not required for correctness with the current implementation of memremap(), for general code hygiene it's better to not depend on the mapping functions doing something reasonable with a physical address that is out-of-range. While here, fix typos in two error messages.

2023-04-17hv_netvsc: Remove second mapping of send and recv buffersMichael Kelley
With changes to how Hyper-V guest VMs flip memory between private (encrypted) and shared (decrypted), creating a second kernel virtual mapping for shared memory is no longer necessary. Everything needed for the transition to shared is handled by set_memory_decrypted(). As such, remove the code to create and manage the second mapping for the pre-allocated send and recv buffers. This mapping is the last user of hv_map_memory()/hv_unmap_memory(), so delete these functions as well. Finally, hv_map_memory() is the last user of vmap_pfn() in Hyper-V guest code, so remove the Kconfig selection of VMAP_PFN.

2023-04-16kbuild: do not create intermediate *.tar for source tarballsMasahiro Yamada
Since commit 05e96e96a315 ("kbuild: use git-archive for source package creation"), a source tarball is created in two steps; create *.tar file then compress it. I split the compression as a separate rule because I just thought 'git archive' supported only gzip. For other compression algorithms, I could pipe the two commands: $ git archive HEAD | xz > linux.tar.xz I read git-archive(1) carefully, and I realized GIT had provided a more elegant way: $ git -c tar.tar.xz.command=xz archive -o linux.tar.xz HEAD This commit uses 'tar.tar.*.command' configuration to specify the compression backend so we can compress a source tarball on-the-fly. GIT commit 767cf4579f0e ("archive: implement configurable tar filters") is more than a decade old, so it should be available on almost all build environments.

Forwarding variadic argument lists can't be done by passing a va_list to a function with signature foo(...) (as panic() has). It ends up interpreting the va_list itself as a single argument instead of iterating it. printf() happily accepts it of course, leading to corrupt output. Convert panic_show_mem() to a macro to allow forwarding the arguments. The function is trivial enough that it's easier than trying to introduce a vpanic() variant.

Similar to commit 4c9d410f32b3 ("initramfs: Check timestamp to prevent broken cpio archive"), except asserts that the timestamp is non-negative. This can happen when the KBUILD_BUILD_TIMESTAMP is a value before UNIX epoch, which may be set when making reproducible builds that don't want to look like they use a valid date. While support for dates before 1970 might not be supported, this is more about preventing undetected CPIO corruption. The printf's use a minimum length format specifier, and will happily make the field longer than 8 characters if they need to.

2023-04-14io_uring: complete request via task work in case of DEFER_TASKRUNMing Lei
So far io_req_complete_post() only covers DEFER_TASKRUN by completing request via task work when the request is completed from IOWQ. However, uring command could be completed from any context, and if io uring is setup with DEFER_TASKRUN, the command is required to be completed from current context, otherwise wait on IORING_ENTER_GETEVENTS can't be wakeup, and may hang forever. The issue can be observed on removing ublk device, but turns out it is one generic issue for uring command & DEFER_TASKRUN, so solve it in io_uring core code.

2023-04-14ALSA: hda/hdmi: disable KAE for Intel DG2Kai Vehmanen
Use of keep-alive (KAE) has resulted in loss of audio on some A750/770 cards as the transition from keep-alive to stream playback is not working as expected. As there is limited benefit of the new KAE mode on discrete cards, revert back to older silent-stream implementation on these systems.

2023-04-13riscv: No need to relocate the dtb as it lies in the fixmap regionAlexandre Ghiti
We used to access the dtb via its linear mapping address but now that the dtb early mapping was moved in the fixmap region, we can keep using this address since it is present in swapper_pg_dir, and remove the dtb relocation. Note that the relocation was wrong anyway since early_memremap() is restricted to 256K whereas the maximum fdt size is 2MB.
