From 4309a1e0d1c39b5ad082e421d003085d38d20595 Mon Sep 17 00:00:00 2001 From: Julien BOIBESSOT Date: Tue, 5 Dec 2017 18:48:14 +0100 Subject: [PATCH] tools/usbip: fixes build with musl libc toolchain MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 77be4c878c72e411ad22af96b6f81dd45c26450a ] Indeed musl doesn't define old SIGCLD signal name but only new one SIGCHLD. SIGCHLD is the new POSIX name for that signal so it doesn't change anything on other libcs. This fixes this kind of build error: usbipd.c: In function ‘set_signal’: usbipd.c:459:12: error: 'SIGCLD' undeclared (first use in this function) sigaction(SIGCLD, &act, NULL); ^~~~~~ usbipd.c:459:12: note: each undeclared identifier is reported only once for each function it appears in Makefile:407: recipe for target 'usbipd.o' failed make[3]: *** [usbipd.o] Error 1 Signed-off-by: Julien BOIBESSOT Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- tools/usb/usbip/src/usbipd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/usb/usbip/src/usbipd.c b/tools/usb/usbip/src/usbipd.c index 009afb4a3aae..c6dad2a13c80 100644 --- a/tools/usb/usbip/src/usbipd.c +++ b/tools/usb/usbip/src/usbipd.c @@ -456,7 +456,7 @@ static void set_signal(void) sigaction(SIGTERM, &act, NULL); sigaction(SIGINT, &act, NULL); act.sa_handler = SIG_IGN; - sigaction(SIGCLD, &act, NULL); + sigaction(SIGCHLD, &act, NULL); } static const char *pid_file;
