MIPS: Place __kernel_entry at the beginning of text section

2024-11-27T00:36:01Z

Mark __kernel_entry as ".head.text" and place HEAD_TEXT before TEXT_TEXT in the linker script. This ensures that __kernel_entry will be placed at the beginning of text section.

Pull vdso data page handling updates from Thomas Gleixner: "First steps of consolidating the VDSO data page handling. The VDSO data page handling is architecture specific for historical reasons, but there is no real technical reason to do so. Aside of that VDSO data has become a dump ground for various mechanisms and fail to provide a clear separation of the functionalities. Clean this up by: - consolidating the VDSO page data by getting rid of architecture specific warts especially in x86 and PowerPC. - removing the last includes of header files which are pulling in other headers outside of the VDSO namespace. - seperating timekeeping and other VDSO data accordingly. Further consolidation of the VDSO page handling is done in subsequent changes scheduled for the next merge window. This also lays the ground for expanding the VDSO time getters for independent PTP clocks in a generic way without making every architecture add support seperately" * tag 'timers-vdso-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (42 commits) x86/vdso: Add missing brackets in switch case vdso: Rename struct arch_vdso_data to arch_vdso_time_data powerpc: Split systemcfg struct definitions out from vdso powerpc: Split systemcfg data out of vdso data page powerpc: Add kconfig option for the systemcfg page powerpc/pseries/lparcfg: Use num_possible_cpus() for potential processors powerpc/pseries/lparcfg: Fix printing of system_active_processors powerpc/procfs: Propagate error of remap_pfn_range() powerpc/vdso: Remove offset comment from 32bit vdso_arch_data x86/vdso: Split virtual clock pages into dedicated mapping x86/vdso: Delete vvar.h x86/vdso: Access vdso data without vvar.h x86/vdso: Move the rng offset to vsyscall.h x86/vdso: Access rng vdso data without vvar.h x86/vdso: Access timens vdso data without vvar.h x86/vdso: Allocate vvar page from C code x86/vdso: Access rng data from kernel without vvar x86/vdso: Place vdso_data at beginning of vvar page x86/vdso: Use __arch_get_vdso_data() to access vdso data x86/mm/mmap: Remove arch_vma_name() ...

fs/xattr: add *at family syscalls

2024-11-06T17:59:44Z

Add the four syscalls setxattrat(), getxattrat(), listxattrat() and removexattrat(). Those can be used to operate on extended attributes, especially security related ones, either relative to a pinned directory or on a file descriptor without read access, avoiding a /proc//fd/ detour, requiring a mounted procfs. One use case will be setfiles(8) setting SELinux file contexts ("security.selinux") without race conditions and without a file descriptor opened with read access requiring SELinux read permission. Use the do_{name}at() pattern from fs/open.c. Pass the value of the extended attribute, its length, and for setxattrat(2) the command (XATTR_CREATE or XATTR_REPLACE) via an added struct xattr_args to not exceed six syscall arguments and not merging the AT_* and XATTR_* flags. [AV: fixes by Christian Brauner folded in, the entire thing rebased on top of {filename,file}_...xattr() primitives, treatment of empty pathnames regularized.

MIPS: Allow using more than 32-bit addresses for reset vectors when possible

2024-10-30T22:45:48Z

While most MIPS64 CPUs use 32-bit values for their VP Local Reset Exception Base registers, some I6500 CPUs can utilize a 64-bit value, allowing addressing up to 47 bits of physical memory. For the EyeQ6H CPU, where physical memory addresses exceed the 4GB limit, utilizing this feature is mandatory to enable SMP support. Unfortunately, there is no way to detect this capability based solely on the ID of the CPU. According to Imagination, which designed the CPU, the only reliable method is to fill the reset base field with 0xFF and then read back its value. If the upper part of the read-back value is zero, it indicates that the address space is limited to 32 bits. Signed-off-by: Gregory CLEMENT Signed-off-by: Thomas Bogendoerfer
