From 51fd67fcbfa598e2fe1885b517451b84c0bfe3b7 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 30 Jul 2019 22:11:39 -0400 Subject: get/setsockopt: add fallback for new time64 SO_RCVTIMEO/SO_SNDTIMEO without this, the SO_RCVTIMEO and SO_SNDTIMEO socket options would stop working on pre-5.1 kernels after time_t is switched to 64-bit and their values are changed to the new time64 versions. new code is written such that it's statically unreachable on 64-bit archs, and on existing 32-bit archs until the macro values are changed to activate 64-bit time_t. --- src/internal/syscall.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/internal/syscall.h') diff --git a/src/internal/syscall.h b/src/internal/syscall.h index 5db18b05..16edf30a 100644 --- a/src/internal/syscall.h +++ b/src/internal/syscall.h @@ -299,6 +299,13 @@ hidden long __syscall_ret(unsigned long), #define __SC_recvmmsg 19 #define __SC_sendmmsg 20 +#ifndef SO_RCVTIMEO_OLD +#define SO_RCVTIMEO_OLD 20 +#endif +#ifndef SO_SNDTIMEO_OLD +#define SO_SNDTIMEO_OLD 21 +#endif + #ifdef SYS_open #define __sys_open2(x,pn,fl) __syscall2(SYS_open, pn, (fl)|O_LARGEFILE) #define __sys_open3(x,pn,fl,mo) __syscall3(SYS_open, pn, (fl)|O_LARGEFILE, mo) -- cgit v1.2.1
