GPT's created by libefi set the HeaderSize attribute in the GPT header to 512 -- size of the GPT header INCLUDING the 420 padding bytes at the end. Most other tools set the size to 92 -- size of the actual header itself excluding the padding. Most tools check the recorded HeaderSize when verifying CRC, but gptfdisk hardcodes 92 and thus reports CRC verification problems for full-disk vdevs created IE with `zpool create pool sdc`. This commit changes libefi's behavior for GPT creation and also fixes several edge cases where libefi's behavior was similar (though in an incompatible manner) to gptfdisk. Libefi assumed HeaderSize was always 512 even if the GPT recorded a different value. Sanity checks of the GPT headersize read from disk were added before applying checksum calculation -- this will prevent segfault in cases of bogus on-disk values. Zpools created with the resuling libefi are verified as correct both by parted and gptfdisk. Also pool have been tested to import correctly on ZFS on Linux as well as Solaris Express 11 livecd.

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
