Each arch that supports audit requires syscall_get_arch() to able to log
and identify architecture-dependent syscall numbers. The information is used
in at least two different subsystems, so standardize it in the same call across
all arches.
Use the standardized syscall_get_arch() locally to add the arch to the
AUDIT_SECCOMP record to identify which syscall was issued.
Since all the callers of syscall_get_arch() presently pass "current" and none
of the arch-specific syscall_get_arch() implementations use the regs parameter,
call syscall_get_arch() locally where it is needed and drop passing around
arch, current and regs in __audit_syscall_entry() and audit_syscall_entry().
Compiles and runs on i686, x86_64, ppc, ppc64, s390, s390x, manually tested in
an x86_64 VM. aarch64 will be added soon.
Richard Guy Briggs (6):
syscall: define syscall_get_arch() for each audit-supported arch
audit: add arch field to seccomp event log
audit: __audit_syscall_entry: ignore arch arg and call
syscall_get_arch() directly
audit: drop arch from audit_syscall_entry() interface
audit: drop args from syscall_get_arch() interface
audit: drop arch from __audit_syscall_entry() interface
