[PATCH] arm64: morello: Enable BINFMT_MISC in defconfig

by Kevin Brodsky

binfmt_misc is notably useful for qemu-user. To enable systemd to automatically mount the binfmt_misc filesystem using autofs, also select AUTOFS_FS (like the standard arm64 defconfig).

[PATCH] mm/(cap_addr_mgmt,mmap) : Fix for mas_empty_area()

by Amit Daniel Kachhap

mas_empty_area() maple tree interface does not work properly and returns -EBUSY if there is no gap in the range. This commit explicitly scans the VMAs for the input range and checks if they are continuous or not. Note: reserv_vmi_range_mapped() can switch to the old method of using mas_empty_area() if this issue is resolved in core maple tree library.

[Announcement] Integration drop 1.8.0 - changelog

by Kevin Brodsky

Hi, The top of the master branch has been tagged [1] as part of the integration drop 1.8.0. Below is the changelog for kernel users, since the previous integration drop (1.7.0). --------- * [Issue #4] The BPF syscall interface has been adapted to operate on full capabilities, while retaining backwards-compatibility with existing arm64 binaries (via 64-bit compat). Please refer to include/uapi/linux/bpf.h [2] for a full list of modified uapi structs. * [Issue #5, #58] User-provided capabilities are now always checked when user memory is accessed (standard uaccess routines such as copy_from_user() now use capability-based loads and stores to perform the access). As a result, passing invalid capabilities to syscalls will typically lead to the syscall failing with -EFAULT. New Morello kselftests have been added to ensure that this capability checking occurs as expected. * The branch has been rebased on the 6.7 upstream release. The morello.rst document has moved under Documentation/arch/arm64 as a result, and a few uapi adaptations have been added for io_uring features that appeared upstream since 6.4. For more details, please refer to this email [3]. * Minor internal refactoring and cleanups related to 64-bit compat support. Contributions ------------- Kudos to everyone who has contributed to Morello Linux! Here are the contributors and number of patches since the previous integration drop: 21 Kevin Brodsky <kevin.brodsky(a)arm.com> 13 Zachary Leaf <zachary.leaf(a)arm.com> 1 Aditya Deshpande <aditya.deshpande(a)arm.com> 1 Akram Ahmad <Akram.Ahmad(a)arm.com> Special thanks are also extended to everyone who has assisted in reviewing these patches.

[PATCH v3 00/25] Introduce mm reservation interface for PCuABI

by Amit Daniel Kachhap

Hi All, This patch series introduces the mm reservation interface to manage the owning capability of the allocated addresses. This series adds reservation details in the VMA structure and different capability/reservation constraint checks. Looking for feedback regarding API names, directory structure etc. Details about several rules implemented can be found in PCuABI spec here [1]. This series is based on tree [2]. Changes in this v3 as compared with v2(Based on suggestions from Kevin): 1) Implemented all suggestion from Kevin on V2 version. However, suggestion to use (unsigned long __user *) instead of user_uintptr_t was not done due to not much benefits and lack of time. 2) vm_mmap() now takes address as unsigned long instead of user_uintptr_t. 3) get_unmapped_area() now checks if address range falling within reservation in case of MAP_FIXED address. 4) New function check_pcuabi_params() added to check parameters sanity in mmap and mremap syscalls. 5) Several fixes and cleanups. 6) Patch 3, 24 and 25 are new patches. Testing: 1) All tests by Chaitanya in v8 selftests [3] passes. 2) Purecap/Compat Busybox boot passes after adding [WIP] patches present in [4]. The whole series can be found here [4].

[PATCH v3] mmc: ioctl: Remove hard-coded MMC_IOC_{MULTI_}CMD values

by Akram Ahmad

The "mmc: Support capabilities in MMC_IOC_{MULTI_}CMD ioctls" patch previously hard-coded the ioctl command value in order to maintain compatibility with non-PCuABI ioctl handlers such as those found in block.c. This deviates from the standard approach which is to always define the ioctl command value in terms of the struct size (which may change), instead providing any fixes in the kernel via compat ioctl handlers. This patch therefore aligns the MMC ioctl handlers in block.c with the standard approach. Undoing the hard-coding in the header leaves the ioctl command value unchanged in all situations except in PCuABI where the structs sizes, and hence the ioctl command values, are now larger (the ioctl value remains unchanged in compat64 as well). The additional comments that were added in the aforementioned patch regarding the changing size of the structs is also removed in this patch.
