The number and types of parameters is such that +no ARM-specific processing is needed, so wiring up sys_accept4() +just requires defining __NR_accept4 and adding a direct call in +the syscall entry table. + +Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original +accept4() test program, modified to define __NR_accept4 for ARM. + +Using the updated unistd.h also eliminates a warning then building +glibc (2.10.2 and newer) about accept4() being unimplemented. + +Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> +Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> +--- + arch/arm/include/asm/unistd.h | 1 + + arch/arm/kernel/calls.S | 1 + + 2 files changed, 2 insertions(+), 0 deletions(-) + +diff --git a/arch/arm/include/asm/unistd.h b/arch/arm/include/asm/unistd.h +index dd2bf53..d02cfb6 100644 +--- a/arch/arm/include/asm/unistd.h ++++ b/arch/arm/include/asm/unistd.h +@@ -392,6 +392,7 @@ + #define __NR_rt_tgsigqueueinfo (__NR_SYSCALL_BASE+363) + #define __NR_perf_event_open (__NR_SYSCALL_BASE+364) + #define __NR_recvmmsg (__NR_SYSCALL_BASE+365) ++#define __NR_accept4 (__NR_SYSCALL_BASE+366) + + /* + * The following SWIs are ARM private. +diff --git a/arch/arm/kernel/calls.S b/arch/arm/kernel/calls.S +index 37ae301..afeb71f 100644 +--- a/arch/arm/kernel/calls.S ++++ b/arch/arm/kernel/calls.S +@@ -375,6 +375,7 @@ + CALL(sys_rt_tgsigqueueinfo) + CALL(sys_perf_event_open) + /* 365 */ CALL(sys_recvmmsg) ++ CALL(sys_accept4) + #ifndef syscalls_counted + .equ syscalls_padding, ((NR_syscalls + 3) & ~3) - NR_syscalls + #define syscalls_counted +-- +1.6.6.1 + |
