From c485b111e69c76a39d5535c0d53050635f0e3314 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 a0972dea9e6c..193556507957 100644 --- a/tools/usb/usbip/src/usbipd.c +++ b/tools/usb/usbip/src/usbipd.c @@ -463,7 +463,7 @@ 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;
