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. Signed-off-by:

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 VMBus monitor pages. Because set_memory_decrypted() and set_memory_encrypted() are no-ops in normal VMs, it's not even necessary to test for being in a Confidential VM (a.k.a., "Isolation VM"). Signed-off-by:

Update the driver to support Devicetree boot as well along with ACPI. At present the Devicetree parsing only provides the mmio region info and is not the exact copy of ACPI parsing. This is sufficient to cater all the current Devicetree usecases for VMBus. Currently Devicetree is supported only for x86 systems. Signed-off-by:

VMBus driver code currently has direct dependency on ACPI and struct acpi_device. As a staging step toward optionally configuring based on Devicetree instead of ACPI, use a more generic platform device to reduce the dependency on ACPI where possible, though the dependency on ACPI is not completely removed. Also rename the function vmbus_acpi_remove() to the more generic vmbus_mmio_remove(). Signed-off-by:

Add a placeholder function for the hv_setup_stimer0_irq API to accommodate systems without ACPI support. Since this function is not utilized on x86/x64 systems and non-ACPI support is only intended for x86/x64 systems, a placeholder function is sufficient for now and can be improved upon if necessary in the future.

Commit 05e96e96 ("kbuild: use git-archive for source package creation") split the compression as a separate step to factor out the common build rules. With the previous commit, we got back to the situation where source tarballs are compressed on-the-fly. There is no reason to keep the separate compression rules. Generate the comressed tar packages directly. Signed-off-by:

Masahiro Yamada authored
Since commit 05e96e96 ("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. Signed-off-by:

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. Signed-off-by:

Similar to commit 4c9d410f ("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. Signed-off-by:

smb311_decode_neg_context() doesn't properly check against SMB packet boundaries prior to accessing individual negotiate context entries. This is due to the length check omitting the eight byte smb2_neg_context header, as well as incorrect decrementing of len_of_ctxts.

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.
