| | | | | | | | | | | | | | | | | | | | | | | | | check hash to the filesystem inodes. Access attempts to files associated with an inode with an invalid check hash will fail with EINVAL (Invalid argument). Access is reestablished after an fsck is run to find and validate the inodes with invalid check-hashes. This check avoids a class of filesystem panics related to corrupted inodes. The hash is done using crc32c. Note this check-hash is for the inode itself and not any of its indirect blocks. Check-hash validation may be extended to also cover indirect block pointers, but that will be a separate (and more costly) feature. Check hashes are added only to UFS2 and not to UFS1 as UFS1 is primarily used in embedded systems with small memories and low-powered processors which need as light-weight a filesystem as possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | folks running filesystems created on check-hash enabled kernels (which I will call "new") on a non-check-hash enabled kernels (which I will call "old). The idea here is to detect when a filesystem is run on an old kernel and flag the filesystem so that when it gets moved back to a new kernel, it will not start getting a slew of check-hash errors. Back when the UFS version 2 filesystem was created, it added a file flag FS_INDEXDIRS that was to be set on any filesystem that kept some sort of on-disk indexing for directories. The idea was precisely to solve the issue we have today. Specifically that a newer kernel that supported indexing would be able to tell that the filesystem had been run on an older non-indexing kernel and that the indexes should not be used until they had been rebuilt. Since we have never implemented on-disk directory indicies, the FS_INDEXDIRS flag is cleared every time any UFS version 2 filesystem ever created is mounted for writing. This commit repurposes the FS_INDEXDIRS flag as the FS_METACKHASH flag. Thus, the FS_METACKHASH is definitively known to have always been cleared. The FS_INDEXDIRS flag has been moved to a new block of flags that will always be cleared starting with this commit (until they get used to implement some future feature which needs to detect that the filesystem was mounted on a kernel that predates the new feature). If a filesystem with check-hashes enabled is mounted on an old kernel the FS_METACKHASH flag is cleared. When that filesystem is mounted on a new kernel it will see that the FS_METACKHASH has been cleared and clears all of the fs_metackhash flags. To get them re-enabled the user must run fsck (in interactive mode without the -y flag) which will ask for each supported check hash whether it should be rebuilt and enabled. When fsck is run in its default preen mode, it will just ignore the check hashes so they will remain disabled. The kernel has always disabled any check hash functions that it does not support, so as more types of check hashes are added, we will get a non-surprising result. Specifically if filesystems get moved to kernels supporting fewer of the check hashes, those that are not supported will be disabled. If the filesystem is moved back to a kernel with more of the check-hashes available and fsck is run interactively to rebuild them, then their checking will resume. Otherwise just the smaller subset will be checked. A side effect of this commit is that filesystems running with cylinder-group check hashes will stop having them checked until fsck is run to re-enable them (since none of them currently have the FS_METACKHASH flag set). So, if you want check hashes enabled on your filesystems after booting a kernel with these changes, you need to run fsck to enable them. Any newly created filesystems will have check hashes enabled. If in doubt as to whether you have check hashes emabled, run dumpfs and look at the list of enabled flags at the end of the superblock details. Notes: svn path=/head/; revision=329051

If a check hash fails when a cylinder group is read, no further allocations are attempted in that cylinder group until it has been fixed by fsck. This avoids a class of filesystem panics related to corrupted cylinder group maps. The hash is done using crc32c. Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily used in embedded systems with small memories and low-powered processors which need as light-weight a filesystem as possible. Specifics of the changes: sys/sys/buf.h: Add BX_FSPRIV to reserve a set of eight b_xflags that may be used by individual filesystems for their own purpose. Their specific definitions are found in the header files for each filesystem that uses them. Also add fields to struct buf as noted below. sys/kern/vfs_bio.c: It is only necessary to compute a check hash for a cylinder group when it is actually read from disk. When calling bread, you do not know whether the buffer was found in the cache or read. So a new flag (GB_CKHASH) and a pointer to a function to perform the hash has been added to breadn_flags to say that the function should be called to calculate a hash if the data has been read. The check hash is placed in b_ckhash and the B_CKHASH flag is set to indicate that a read was done and a check hash calculated. Though a rather elaborate mechanism, it should also work for check hashing other metadata in the future. A kernel internal API change was to change breada into a static fucntion and add flags and a function pointer to a check-hash function. sys/ufs/ffs/fs.h: Add flags for types of check hashes; stored in a new word in the superblock. Define corresponding BX_ flags for the different types of check hashes. Add a check hash word in the cylinder group. sys/ufs/ffs/ffs_alloc.c: In ffs_getcg do the dance with breadn_flags to get a check hash and if one is provided, check it. sys/ufs/ffs/ffs_vfsops.c: Copy across the BX_FFSTYPES flags in background writes. Update the check hash when writing out buffers that need them. sys/ufs/ffs/ffs_snapshot.c: Recompute check hash when updating snapshot cylinder groups. sys/libkern/crc32.c: lib/libufs/Makefile: lib/libufs/libufs.h: lib/libufs/cgroup.c: Include libkern/crc32.c in libufs and use it to compute check hashes when updating cylinder groups. Four utilities are affected: sbin/newfs/mkfs.c: Add the check hashes when building the cylinder groups. sbin/fsck_ffs/fsck.h: sbin/fsck_ffs/fsutil.c: Verify and update check hashes when checking and writing cylinder groups. sbin/fsck_ffs/pass5.c: Offer to add check hashes to existing filesystems. Precompute check hashes when rebuilding cylinder group (although this will be done when it is written in fsutil.c it is necessary to do it early before comparing with the old cylinder group) sbin/dumpfs/dumpfs.c Print out the new check hash flag(s) sbin/fsdb/Makefile: Needs to add libufs now used by pass5.c imported from fsck_ffs.
