From: guenther Date: Thu, 18 May 2023 16:11:09 +0000 (+0000) Subject: Add PROTO_NORMAL() declarations for the remaining syscalls, to avoid X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=170ca6cd9aafa3cdc31a31ea372066cfe462e34a;p=openbsd Add PROTO_NORMAL() declarations for the remaining syscalls, to avoid future, inadvertant PLT entries. Move the __getcwd and __realpath declarations to hidden/{stdlib,unistd}.h to consolidate and remove duplication. ok tb@ otto@ deraadt@ --- diff --git a/lib/libc/compat-43/getwd.c b/lib/libc/compat-43/getwd.c index 2ae13683744..824d827f70c 100644 --- a/lib/libc/compat-43/getwd.c +++ b/lib/libc/compat-43/getwd.c @@ -1,4 +1,4 @@ -/* $OpenBSD: getwd.c,v 1.13 2021/12/16 19:12:43 millert Exp $ */ +/* $OpenBSD: getwd.c,v 1.14 2023/05/18 16:11:09 guenther Exp $ */ /*- * Copyright (c) 1990 The Regents of the University of California. * All rights reserved. @@ -34,9 +34,6 @@ #include #include -int __getcwd(char *buf, size_t len); -PROTO_NORMAL(__getcwd); - char * getwd(char *buf) { diff --git a/lib/libc/gen/getcwd.c b/lib/libc/gen/getcwd.c index 7197276d8d7..1bc9065563d 100644 --- a/lib/libc/gen/getcwd.c +++ b/lib/libc/gen/getcwd.c @@ -1,4 +1,4 @@ -/* $OpenBSD: getcwd.c,v 1.21 2016/05/07 19:48:00 guenther Exp $ */ +/* $OpenBSD: getcwd.c,v 1.22 2023/05/18 16:11:09 guenther Exp $ */ /* * Copyright (c) 2005 Marius Eriksen @@ -21,9 +21,6 @@ #include #include -int __getcwd(char *buf, size_t len); -PROTO_NORMAL(__getcwd); - char * getcwd(char *buf, size_t size) { diff --git a/lib/libc/hidden/stdlib.h b/lib/libc/hidden/stdlib.h index 5753c32945f..46c3536715d 100644 --- a/lib/libc/hidden/stdlib.h +++ b/lib/libc/hidden/stdlib.h @@ -1,4 +1,4 @@ -/* $OpenBSD: stdlib.h,v 1.16 2019/05/10 15:03:24 otto Exp $ */ +/* $OpenBSD: stdlib.h,v 1.17 2023/05/18 16:11:09 guenther Exp $ */ /* $NetBSD: stdlib.h,v 1.25 1995/12/27 21:19:08 jtc Exp $ */ /*- @@ -45,11 +45,14 @@ __END_HIDDEN_DECLS extern char **environ; extern char *__progname; +int __realpath(const char *pathname, char *resolved); + #if 0 /*extern PROTO_NORMAL(suboptarg);*/ #endif PROTO_NORMAL(__mb_cur_max); +PROTO_NORMAL(__realpath); PROTO_STD_DEPRECATED(_Exit); PROTO_DEPRECATED(a64l); PROTO_NORMAL(abort); diff --git a/lib/libc/hidden/sys/event.h b/lib/libc/hidden/sys/event.h new file mode 100644 index 00000000000..7e129b8aab4 --- /dev/null +++ b/lib/libc/hidden/sys/event.h @@ -0,0 +1,26 @@ +/* $OpenBSD: event.h,v 1.1 2023/05/18 16:11:09 guenther Exp $ */ +/* + * Copyright (c) 2023 Philip Guenther + * + * Permission to use, copy, modify, and distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
