This one looks better, but failes to compile: http://bugs.funtoo.org/secure/attachment/11099/0001-missing-Don-t-call-syscall-with-syscallno-1.patch libkmod/missing.h:27:17: error: '__NR_finit_module' undeclared (first use in this function) I've changed your patch a little (put the real call into the #else branch). With this version, I don't see the problem any more. ---- From: Lucas De Marchi <lucas.de.marchi@xxxxxxxxx> Date: Thu, 2 May 2013 13:22:57 -0300 Subject: [PATCH] missing: Don't call syscall() with syscallno == -1 Reported-by: Jean-Francis Roy <jeanfrancis@xxxxxxxxxx> Reported-by: Jan Luebbe <jlu@xxxxxxxxxxxxxx> --- libkmod/missing.h | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/libkmod/missing.h b/libkmod/missing.h index edb88b9..b31af84 100644 --- a/libkmod/missing.h +++ b/libkmod/missing.h @@ -1,5 +1,6 @@ #pragma once +#include <errno.h> #include <unistd.h> #include <sys/syscall.h> @@ -15,13 +16,14 @@ # define MODULE_INIT_IGNORE_VERMAGIC 2 #endif -#ifndef __NR_finit_module -# define __NR_finit_module -1 -#endif - #ifndef HAVE_FINIT_MODULE static inline int finit_module(int fd, const char *uargs, int flags) { +#ifndef __NR_finit_module + errno = ENOSYS; + return -1; +#else return syscall(__NR_finit_module, fd, uargs, flags); +#endif } #endif -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- To unsubscribe from this list: send the line "unsubscribe linux-modules" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
