in-core pointers to summary information. An array in this region (fs_csp) could overflow on filesystems with a very large number of cylinder groups (~16000 on i386 with 8k blocks). When this happens, other fields in the superblock get corrupted, and fsck refuses to check the filesystem. Solve this problem by replacing the fs_csp array in 'struct fs' with a single pointer, and add padding to keep the length of the 128-byte region fixed. Update the kernel and userland utilities to use just this single pointer. With this change, the kernel no longer makes use of the superblock fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c to indicate that these fields must be calculated for compatibility with older kernels. Reviewed by: mckusick |
