Subject: [PATCH] openat2: define _GNU_SOURCE and include <fcntl.h>
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
||
|
||
On Fedora Rawhide (glibc 2.43+), libc exposes openat2() and struct open_how,
|
||
so our configure script defines HAVE_OPENAT2 and the fallback definition in
|
||
lapi/openat2.h gets skipped. But openat20*.c never included <fcntl.h> (and
|
||
lacked _GNU_SOURCE), so the libc-provided prototype and struct stayed hidden,
|
||
so compilation failed:
|
||
|
||
# uname -r
|
||
6.18.0-65.fc44.x86_64
|
||
|
||
# rpm -qf /usr/include/fcntl.h
|
||
glibc-devel-2.43-1.fc44.x86_64
|
||
|
||
# nm -D /usr/lib64/libc.so.6 | grep -w openat2
|
||
00000000000eb890 W openat2@@GLIBC_2.43
|
||
|
||
# make -C testcase/kernel/syscalls/openat2
|
||
openat201.c:27:62: error: invalid application of ‘sizeof’ to incomplete type ‘struct open_how’
|
||
27 | {&dir_fd, TEST_FILE, O_RDWR, S_IRWXU, 0, &how, sizeof(*how)},
|
||
|
||
Define _GNU_SOURCE and include <fcntl.h> in openat2 tests to make the
|
||
prototype available and fix the build.
