The realpath(3) function expects that when a buffer is passed for the 'resolved_path' that it be at least PATH_MAX in length. If it's not a buffer overflow may occur. Therefore the passed buffer size is changed from MAXNAMELEN to MAXPATHLEN. We also take this opertunity to dynamically allocate the buffer to keep it off the stack. warning: call to '__realpath_chk_warn' declared with attribute warning: second argument of realpath must be either NULL or at least PATH_MAX bytes long buffer [enabled by default] Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
To copy the kernel code inside your kernel source tree for builtin compilation:
$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...
Full documentation for building, configuring, and using ZFS can be found at: http://zfsonlinux.org
