* Be more careful when checking superblock. We have already checkedXin LI2008-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | whether fs_bsize is larger than MINBSIZE, which is larger than the value that is used to compared with fs_bsize, the sizeof fs, so the check followed, will be always true. By inspecting the code and some old commit log, I believe that the check must be that *fs_sbsize* is larger than sizeof fs. We round up the size to nearest dev_bsize, as the smallest accepted fs_sbsize, personally, I think this can be even changed to equal, because this number is mostly an invariant in file systems. With this check, fsck_ffs(8) will be more picky and has better chance rejecting bad first superblock rather than referring to bad value it supplied, thus gives better chance for it to check the filesystem carefully.

* Make background fsck based summary adjustments actually work byXin LI2005-03-071-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | initializing the sysctl mibs data before actually using them. The original patchset (which is the actual version that is running on my testboxes) have checked whether all of these sysctls and refuses to do background fsck if we don't have them. Kirk has pointed out that refusing running fsck on old kernels is pointless, as old kernels will recompute the summary at mount time, so I have removed these checks. Unfortunatelly, as the checks will initialize the mib values of those sysctl's, and which are vital for the runtime summary adjustment to work, we can not simply remove the check, which will lead to problem when running background fsck over a dirty volume. Add these checks in a different way: give a warning rather than refusing to work, and complain if the functionality is not available when adjustments are necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | filesystem expands the inode to 256 bytes to make space for 64-bit block pointers. It also adds a file-creation time field, an ability to use jumbo blocks per inode to allow extent like pointer density, and space for extended attributes (up to twice the filesystem block size worth of attributes, e.g., on a 16K filesystem, there is space for 32K of attributes). UFS2 fully supports and runs existing UFS1 filesystems. New filesystems built using newfs can be built in either UFS1 or UFS2 format using the -O option. In this commit UFS1 is the default format, so if you want to build UFS2 format filesystems, you must specify -O 2. This default will be changed to UFS2 when UFS2 proves itself to be stable. In this commit the boot code for reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c) as there is insufficient space in the boot block. Once the size of the boot block is increased, this code can be defined. Things to note: the definition of SBSIZE has changed to SBLOCKSIZE. The header file <ufs/ufs/dinode.h> must be included before <ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and ufs_lbn_t. Still TODO: Verify that the first level bootstraps work for all the architectures. Convert the utility ffsinfo to understand UFS2 and test growfs. Add support for the extended attribute storage. Update soft updates to ensure integrity of extended attribute storage. Switch the current extended attribute interfaces to use the extended attribute storage.

| | | | | | | | | | | | | | | | | that might have changed, then did a byte-by-byte comparison with the alternate. If any unused fields got used, they had to be added to the exception list. Such changes caused too many false alarms. So, I have changed the comparison algorithm to compare a selected set of fields that are not expected to change. This new algorithm causes far fewer false hits and still does a good job of detecting problems when they have really occurred. In particular, this change should ease the transition to kernels supporting UFS2 which make some significant changes to the superblock.

* Fsck_ffs did not properly range-check the inode 'di_size'Ian Dowse2001-01-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | field, so it was possible for a filesystem marked clean by fsck_ffs to cause kernel crashes later when mounted. This could occur when fsck_ffs was used to repair a badly corrupted filesystem. As pointed out by bde, it is not sufficient to restrict di_size to just the superblock fs_maxfilesize limit. The use of 32-bit logical block numbers (both in fsck and the kernel) induces another file size limit which is usually lower than fs_maxfilesize. Also, the old 4.3BSD filesystem does not have fs_maxfilesize initialised. Following this change, fsck_ffs will enforce exactly the same file size limits as are used by the kernel.

* The ffs superblock includes a 128-byte region for use by temporaryIan Dowse2001-01-151-3/+4
| | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=71073

Newfs does not change the label at all, so there is no problem (except the breakage of the automatic search for backup superblocks) unless something else sets the partition type to 4.2BSD.
