BUG: https://bugzilla.samba.org/show_bug.cgi?id=14817
(cherry picked from commit 290c1dc097)
F_GETLEASE/F_SETLEASE are available (at least) since Linux 2.4.0 from
2002.
We also should not have the configure check depend on the filesystem
we find at build time. It's very common that the build-environment is
much more restricted than the runtime-environment will be.
As a history we had this check on Samba 3.6:
AC_CACHE_CHECK([for Linux kernel oplocks],samba_cv_HAVE_KERNEL_OPLOCKS_LINUX,[
AC_TRY_RUN([
#include <sys/types.h>
#include <fcntl.h>
#ifndef F_GETLEASE
#define F_GETLEASE 1025
#endif
main() {
int fd = open("/dev/null", O_RDONLY);
return fcntl(fd, F_GETLEASE, 0) == -1;
}
],
samba_cv_HAVE_KERNEL_OPLOCKS_LINUX=yes,samba_cv_HAVE_KERNEL_OPLOCKS_LINUX=no,samba_cv_HAVE_KERNEL_OPLOCKS_LINUX=cross)])
if test x"$samba_cv_HAVE_KERNEL_OPLOCKS_LINUX" = x"yes"; then
AC_DEFINE(HAVE_KERNEL_OPLOCKS_LINUX,1,[Whether to use linux kernel oplocks])
fi
which didn't depend on the filesystem.
Then we got a broken check introduced in Samba 4.0 (a copy of the
F_NOTIFY check):
# Check for Linux kernel oplocks
conf.CHECK_CODE('''
#include <sys/types.h>
#include <fcntl.h>
#include <signal.h>
#ifndef F_NOTIFY
#define F_NOTIFY 1026
#endif
main() {
exit(fcntl(open("/tmp", O_RDONLY), F_NOTIFY, 0) == -1 ? 1 : 0);
}''', 'HAVE_KERNEL_OPLOCKS_LINUX', addmain=False, execute=True,
msg="Checking for Linux kernel oplocks")
this got "fixed" in Samba 4.7 (and backports to 4.6, 4.5 and 4.4) into
# Check for Linux kernel oplocks
conf.CHECK_CODE('''
#include <sys/types.h>
#include <fcntl.h>
#include <signal.h>
#ifndef F_GETLEASE
#define F_GETLEASE 1025
#endif
main() {
exit(fcntl(open("/tmp", O_RDONLY), F_GETLEASE, 0) == -1 ? 1 : 0);
}''', 'HAVE_KERNEL_OPLOCKS_LINUX', addmain=False, execute=True,
msg="Checking for Linux kernel oplocks")
Lately it became dependend on the filesystem in the build-environment:
# Check for Linux kernel oplocks
conf.CHECK_CODE('''
#include <sys/types.h>
#include <fcntl.h>
#include <signal.h>
#ifndef F_GETLEASE
#define F_GETLEASE 1025
#endif
main() {
const char *fname="/tmp/oplock-test.txt";
int fd = open(fname, O_RDWR|O_CREAT, 0644);
int ret = fcntl(fd, F_SETLEASE, F_WRLCK);
unlink(fname);
return (ret == -1) ? 1 : 0;
}''', 'HAVE_KERNEL_OPLOCKS_LINUX', addmain=False, execute=True,
msg="Checking for Linux kernel oplocks")
Now we just check for F_SETLEASE being available in linux/fcntl.h.

lib/util/safe_string.h is similar to source3/include/safe_string.h, but
the former has fewer checks. It is missing bcopy, strcasecmp, and
strncasecmp.
Add the missing elements to lib/util/safe_string.h remove the other
safe_string.h which is in the source3-specific path. To accomodate
existing uses of str(n?)casecmp, add #undef lines to source files where
they are used.

Commit 810397f89a, and possibly others, broke the build for macOS and
other environments which don't have st_[acm]tim fields on 'struct stat'.
Multiple places in the codebase used the config.h values to determine
how to access the nanosecond or microsecond values of the stat
timestamps, so rather than add more, centralize them all into
lib/util/time.c.
Also allow pvfs_fileinfo.c to read nanosecond-granularity timestamps on
platforms where it didn't before, since its #if branches were not
complete.

This uses the Linux libaio that does not meet Samba's needs. If
someone wanted to add async I/O to ntvfs, the io_uring API is the way
to go. Second option would be to use a pthreads-based API.

While this could have been a very interesting idea (particularly
if it allowed our main SMB server to disable SMB1), it has never
been enabled in our testsuite so relying on it would be quite
brave.
