Here is a minimal test case that reproduces the problem at mine. Run it
as un unprivilegied user in a directory you on which you have write
access:
$ pwd
/pfs/manu/xinstall
$ ls -ld .
drwxr-xr-x 4 manu manu 512 May 26 16:17 .
$ id
uid=500(manu) gid=500(manu) groups=500(manu),0(wheel)
$ ./test
test: fchmod failed: Permission denied
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <err.h>
#include <errno.h>
#include <sysexits.h>
#include <sys/stat.h>
#define TESTFILE "testfile"
int
main(void)
{
int fd;
char buf[16384];
if ((unlink(TESTFILE) == -1) && (errno != ENOENT))
err(EX_OSERR, "unlink failed");
if ((fd = open(TESTFILE, O_CREAT|O_EXCL|O_RDWR, 0600)) == -1)
err(EX_OSERR, "open failed");
if (write(fd, buf, sizeof(buf)) != sizeof(buf))
err(EX_OSERR, "write failed");
if (fchmod(fd, 0555) == -1)
err(EX_OSERR, "fchmod failed");
if (close(fd) == -1)
err(EX_OSERR, "close failed");
return EX_OK;
}
