| * debugfs: add the ability to manipulate the extent tree directlyTheodore Ts'o2012-12-241-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds the functionality which had previously only been in the tst_extents command to debugfs. The debugfs command extent_open will open extent tree of a particular inode, and enables a series of commands which will allow the user to interact with the extent tree directly. Once the extent tree is closed via extent_open(), these additional commands will be disabled again. This commit exports two new functions from lib/ext2fs/extent.c which had previously been statically defined: ext2fs_extent_node_split() and ext2fs_extent_goto2().

* | libext2fs: block group checksum should use metadata_csum algorithmDarrick J. Wong2012-08-021-2/+1
| | | | | | | | | | | | | | | | | | | | | | Change the block group algorithm to use the same algorithm as the rest of the metadata_csum. This mostly involves providing a helper function to tell if group descriptors should have checksums set or verified, and modifying the gdt checksum code to use the correct algorithm.

| | | | | | | | | | | Create a version of debugfs which only supports read-only examination of the file system metadata (but not the data blocks). The idea is that this version of debugfs might be suitable to be setuid root, and executable only by members of a particular group, or setgid disk, and globally executable, depending on the security/privacy policies in force at a particular site.

* libext2fs: ext2fs_[set_]file_acl_block needs to check for 64-bit feature flagTheodore Ts'o2011-10-161-1/+1
| | | | | | | | | | | | | | | | The ext2fs_file_acl_block() and ext2fs_set_file_acl_block() needs to only check i_file_acl_high if the 64-bit flag is set. This is needed because otherwise we will run into problems on Hurd systems which actually use that field for h_i_mode_high. This involves an ABI change since we need to pass ext2_filsys to these functions. Fortunately these functions were first included in the 1.42-WIP series, so it's OK for us to change them now. (This is why we have 1.42-WIP releases. :-) Addresses-Sourceforge-Bug: #3379227 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* ext2fs: add multi-mount protection (INCOMPAT_MMP)Andreas Dilger2011-09-251-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | Multi-mount protection is feature that allows mke2fs, e2fsck, and others to detect if the filesystem is mounted on a remote node (on SAN disks) and avoid corrupting the filesystem. For e2fsprogs this means that it checks the MMP block to see if the filesystem is in use, and marks the filesystem busy while e2fsck is running on the system. This is useful on SAN disks that are shared between high-availability servers, or accessible by multiple nodes that aren't in HA pairs. MMP isn't intended to serve as a primary HA exclusion mechanism, but as a failsafe to protect against user, software, or hardware errors. There is no requirement that e2fsck updates the MMP block at regular intervals, but e2fsck does this occasionally to provide useful information to the sysadmin in case of a detected conflict. For the kernel (since Linux 3.0) MMP adds a "heartbeat" mechanism to periodically write to disk (every few seconds by default) to notify other nodes that the filesystem is still in use and unsafe to modify.

* Shorten compile commands run by the build systemTheodore Ts'o2011-09-181-0/+1
| | | | | | | | | | | | | | | The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and this was starting to cause some tools heartburn. It also made "make V=1" almost useless, since trying to following the individual commands run by make was lost in the noise of all of the defines. So fix this by putting the configure-generated defines in lib/config.h and the directory pathnames to lib/dirpaths.h. In addition, clean up some vestigal defines in configure.in and in the Makefiles to further shorten the cc command lines. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
