ptrace, treewide: Rename ptrace_report_syscall_entry() to ptrace_report_syscall_permit_entry()

2026-07-12T10:38:02+00:00

The return value of that function is boolean and tells the caller whether to permit the syscall processing or not. Rename the function so the purpose is clear and make the return type bool.

syscall.h: introduce syscall_set_nr()

2025-05-12T00:48:15+00:00

Similar to syscall_set_arguments() that complements syscall_get_arguments(), introduce syscall_set_nr() that complements syscall_get_nr(). syscall_set_nr() is going to be needed along with syscall_set_arguments() on all HAVE_ARCH_TRACEHOOK architectures to implement PTRACE_SET_SYSCALL_INFO API.

syscall.h: add syscall_set_arguments()

2025-05-12T00:48:15+00:00

This function is going to be needed on all HAVE_ARCH_TRACEHOOK architectures to implement PTRACE_SET_SYSCALL_INFO API. This partially reverts commit 7962c2eddbfe ("arch: remove unused function syscall_set_arguments()") by reusing some of old syscall_set_arguments() implementations.

audit: Migrate to use SYSCALL_WORK flag

2020-11-16T20:53:16+00:00

On architectures using the generic syscall entry code the architecture independent syscall work is moved to flags in thread_info::syscall_work. This removes architecture dependencies and frees up TIF bits. Define SYSCALL_WORK_SYSCALL_AUDIT, use it in the generic entry code and convert the code which uses the TIF specific helper functions to use the new *_syscall_work() helpers which either resolve to the new mode for users of the generic entry code or to the TIF based functions for the other architectures.
