From ac3e262cba81889c0bb04ce87a50a1709f2726e7 Mon Sep 17 00:00:00 2001 From: Petr Vorel Date: Thu, 1 Oct 2020 23:28:39 +0200 Subject: [PATCH] lapi: Add sysinfo.h to fix build with MUSL libc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The reason is to avoid indirect include when using some network headers: or others -> -> This indirect include causes on MUSL redefinition of struct sysinfo when included both and some of UAPI headers: In file included from x86_64-buildroot-linux-musl/sysroot/usr/include/linux/kernel.h:5, from x86_64-buildroot-linux-musl/sysroot/usr/include/linux/netlink.h:5, from ../include/tst_netlink.h:14, from tst_crypto.c:13: x86_64-buildroot-linux-musl/sysroot/usr/include/linux/sysinfo.h:8:8: error: redefinition of ‘struct sysinfo’ struct sysinfo { ^~~~~~~ In file included from ../include/tst_safe_macros.h:15, from ../include/tst_test.h:93, from tst_crypto.c:11: x86_64-buildroot-linux-musl/sysroot/usr/include/sys/sysinfo.h:10:8: note: originally defined here Signed-off-by: Petr Vorel [ upstream status: https://patchwork.ozlabs.org/project/ltp/patch/20201001231256.6930-1-petr.vorel@gmail.com/ ] --- include/lapi/sysinfo.h | 22 +++++++++++++++++++ include/tst_safe_macros.h | 2 +- lib/safe_macros.c | 2 +- lib/tst_memutils.c | 2 +- testcases/kernel/mem/mtest01/mtest01.c | 2 +- testcases/kernel/syscalls/madvise/madvise06.c | 2 +- testcases/kernel/syscalls/sysinfo/sysinfo01.c | 2 +- testcases/kernel/syscalls/sysinfo/sysinfo02.c | 2 +- testcases/kernel/syscalls/sysinfo/sysinfo03.c | 2 +- 9 files changed, 30 insertions(+), 8 deletions(-) create mode 100644 include/lapi/sysinfo.h diff --git a/include/lapi/sysinfo.h b/include/lapi/sysinfo.h new file mode 100644 index 000000000..d0e0e93d7 --- /dev/null +++ b/include/lapi/sysinfo.h @@ -0,0 +1,22 @@ +// SPDX-License-Identifier: GPL-2.0-or-later +/* + * Copyright (c) 2020 Petr Vorel + */ + +#ifndef SYSINFO_H__ + +/* + * Don't use as it breaks build MUSL toolchain. + * Use instead. + * + * Some kernel UAPI headers do indirect include: + * or others -> -> + * + * This indirect include causes on MUSL redefinition of struct sysinfo when + * included both and some of UAPI headers: + */ +#include + +#define SYSINFO_H__ + +#endif /* SYSINFO_H__ */ diff --git a/include/tst_safe_macros.h b/include/tst_safe_macros.h index 053c3bcf9..61ea2076d 100644 --- a/include/tst_safe_macros.h +++ b/include/tst_safe_macros.h @@ -12,7 +12,7 @@ #include #include #include -#include +#include #include #include #include diff --git a/lib/safe_macros.c b/lib/safe_macros.c index 4f48d7529..d8ee03dae 100644 --- a/lib/safe_macros.c +++ b/lib/safe_macros.c @@ -11,7 +11,6 @@ #include #include #include -#include #include #include #include @@ -23,6 +22,7 @@ #include #include "test.h" #include "safe_macros.h" +#include "lapi/sysinfo.h" char *safe_basename(const char *file, const int lineno, void (*cleanup_fn) (void), char *path) diff --git a/lib/tst_memutils.c b/lib/tst_memutils.c index f134d90c9..647db951e 100644 --- a/lib/tst_memutils.c +++ b/lib/tst_memutils.c @@ -5,11 +5,11 @@ #include #include -#include #include #define TST_NO_DEFAULT_MAIN #include "tst_test.h" +#include "lapi/sysinfo.h" #define BLOCKSIZE (16 * 1024 * 1024) diff --git a/testcases/kernel/mem/mtest01/mtest01.c b/testcases/kernel/mem/mtest01/mtest01.c index f08d3943f..9b4d856f8 100644 --- a/testcases/kernel/mem/mtest01/mtest01.c +++ b/testcases/kernel/mem/mtest01/mtest01.c @@ -20,7 +20,6 @@ */ #include -#include #include #include #include @@ -29,6 +28,7 @@ #include #include "lapi/abisize.h" +#include "lapi/sysinfo.h" #include "tst_test.h" #define FIVE_HUNDRED_MB (500ULL*1024*1024) diff --git a/testcases/kernel/syscalls/madvise/madvise06.c b/testcases/kernel/syscalls/madvise/madvise06.c index f76f3f6aa..b2613670b 100644 --- a/testcases/kernel/syscalls/madvise/madvise06.c +++ b/testcases/kernel/syscalls/madvise/madvise06.c @@ -24,8 +24,8 @@ #include #include #include -#include #include "tst_test.h" +#include "lapi/sysinfo.h" #define CHUNK_SZ (400*1024*1024L) #define CHUNK_PAGES (CHUNK_SZ / pg_sz) diff --git a/testcases/kernel/syscalls/sysinfo/sysinfo01.c b/testcases/kernel/syscalls/sysinfo/sysinfo01.c index 2ea44a2be..a95066bf5 100644 --- a/testcases/kernel/syscalls/sysinfo/sysinfo01.c +++ b/testcases/kernel/syscalls/sysinfo/sysinfo01.c @@ -69,9 +69,9 @@ #include #include #include -#include #include "test.h" +#include "lapi/sysinfo.h" void setup();
