From e4da89d02f369450996cfd04f64b1cce4d8afaea Mon Sep 17 00:00:00 2001 From: Will Drewry Date: Tue, 17 Apr 2012 14:48:57 -0500 Subject: seccomp: ignore secure_computing return values This change is inspired by https://lkml.org/lkml/2012/4/16/14 which fixes the build warnings for arches that don't support CONFIG_HAVE_ARCH_SECCOMP_FILTER. In particular, there is no requirement for the return value of secure_computing() to be checked unless the architecture supports seccomp filter. Instead of silencing the warnings with (void) a new static inline is added to encode the expected behavior in a compiler and human friendly way. v2: - cleans things up with a static inline - removes sfr's signed-off-by since it is a different approach v1: - matches sfr's original change Reported-by: Stephen Rothwell Signed-off-by: Will Drewry Acked-by: Kees Cook Signed-off-by: James Morris --- arch/mips/kernel/ptrace.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/mips') diff --git a/arch/mips/kernel/ptrace.c b/arch/mips/kernel/ptrace.c index 7c24c2973c6d..4812c6d916e4 100644 --- a/arch/mips/kernel/ptrace.c +++ b/arch/mips/kernel/ptrace.c @@ -535,7 +535,7 @@ static inline int audit_arch(void) asmlinkage void syscall_trace_enter(struct pt_regs *regs) { /* do the secure computing check first */ - secure_computing(regs->regs[2]); + secure_computing_strict(regs->regs[2]); if (!(current->ptrace & PT_PTRACED)) goto out; -- cgit v1.2.3
