* Fix fsck_ffs build with a 64-bit ino_t.mdf2012-09-271-9/+11
| | | | Original code by: Gleb Kurtsou
* Replace index() and rindex() calls with strchr() and strrchr().ed2012-01-031-1/+1
| | | | | | | | | | The index() and rindex() functions were marked LEGACY in the 2001 revision of POSIX and were subsequently removed from the 2008 revision. The strchr() and strrchr() functions are part of the C standard. This makes the source code a lot more consistent, as most of these C files also call into other str*() routines. In fact, about a dozen already perform strchr() calls.

* When renaming a directory it passes through several intermediatemckusick2010-01-111-21/+109
| | | | | | | | | | | | | | | | | | | | | | | | states. First its new name will be created causing it to have two names (from possibly different parents). Next, if it has different parents, its value of ".." will be changed from pointing to the old parent to pointing to the new parent. Concurrently, its old name will be removed bringing it back into a consistent state. When fsck encounters an extra name for a directory, it offers to remove the "extraneous hard link"; when it finds that the names have been changed but the update to ".." has not happened, it offers to rewrite ".." to point at the correct parent. Both of these changes were considered unexpected so would cause fsck in preen mode or fsck in background mode to fail with the need to run fsck manually to fix these problems. This update changes these errors to be expected so that in preen mode fsck will simply fix these transitional errors. For now, background fsck will note these errors, but will need additional kernel support to fix them, so will simply ignore them rather than fail. A future update will allow background fsck to fix these problems. Reported by: jeff

* This commit adds basic support for the UFS2 filesystem. The UFS2mckusick2002-06-211-16/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Add the extent like functionality (framework is there, but is currently never used). Sponsored by: DARPA & NAI Labs. Reviewed by: Poul-Henning Kamp <phk@freebsd.org>

To try out this change, set the fsck passno to zero in /etc/fstab to cause the filesystem to be mounted without running fsck, then run `fsck_ffs -p -B <filesystem>' after the system has been brought up multiuser to run a background cleanup on <filesystem>. Note that the <filesystem> in question must have soft updates enabled.
