Kirk McKusick 93440bbefd The binary representation of the superblock (the fs structure) is written ... out verbatim to the disk: see ffs_sbput() in sys/ufs/ffs/ffs_subr.c. It contains a pointer to the fs_summary_info structure. This pointer value inadvertently causes garbage to be stored. It is garbage because the pointer to the fs_summary_info structure is the address the then current stack or heap. Although a mere pointer does not reveal anything useful (like a part of a private key) to an attacker, garbage output deteriorates reproducibility. This commit zeros out the pointer to the fs_summary_info structure before writing the out the superblock.
