Hello,
I am trying to recursively check/change projid on a directory that
contains symlinks among other files. The way I do it is like this
(attributes reading part as an example, modulo error handling):
oflags = O_NOFOLLOW | O_RDONLY;
if (S_ISDIR(stat->st_mode))
oflags |= O_DIRECTORY;
if (S_ISLNK(stat->st_mode))
oflags |= O_PATH;
fd = open(path, oflags, 0);
xfsctl(NULL, fd, XFS_IOC_FSGETXATTR, &attr);
The xfsctl() call fails with EBADF. Apparently this is because
xfsctl() is implemented as ioctl(), at least on Linux, which doesn't
work with file descriptors obtained with O_PATH. Is there any way to
manipulate projid on symlinks?
Thanks!
