* Add files that would normally be generated by the e2fsprogs build systemBernhard Rosenkränzer2014-01-051-1/+0
| | | | | | | | | | | | | | | | | Android doesn't run ./configure and friends, so it has to rely on pre-populated versions of the autogenerated files. This is somewhat bogus (e.g. hardcoded little-endian reference in lib/ext2fs/ext2_types.h) and should at some point be fixed, but it's what Android has always done, not a regression from the 1.41.14 branch. Also, don't #include config.h which we don't generate (we pass what it usually contains as -D parameters from Android.mk) anywhere. Add a new Android.mk file for the quota library.

* libext2fs, libe2p: Reserve RO_COMPAT_REPLICA featureTheodore Ts'o2012-02-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The replica is a feature which stores multiple copies of the key metadata blocks so a single block failure in failure-prone media (read: certain types of flash storage) doesn't take out the entire file system. Discussion on the upstream list proved not to be very positive on this feature; the arguments were that it added complexity that wasn't warrented, since common practice in industry is to insist on reliable media, and if media is unreliable, you're kind of toast anyway (unless the file system is being used as the back-end store of a cluster file system where checksuming and data replication is happening above the local disk file system level). So, this feature is being developed out of tree. We reserve the code points so that other people won't accidentally step on them. Since it's not upstream, it's a soft reservation, but it's not like we have any shortage of RO_COMPAT features. We are a bit more tight on reserved inodes, but EXT2_BOOT_LOADER_INO and EXT2_UNDEL_DIR_INO are not currently used anywhere, and EXT2_EXCLUDE_INO is a reservation for another out-of-tree feature. There are no features currently being discussed which require a reserved inode, but if a need were to arise, we can claw back code point reservations that were never used or not in tree, as those will always be considered lower priority than in-tree features.

* ext2fs: add multi-mount protection (INCOMPAT_MMP)Andreas Dilger2011-09-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* debugfs: add 64-bit support to the set_field commandsTheodore Ts'o2011-09-161-1/+1
| | | | | | | | | | | | | The set_fields commands (set_super_value, set_inode_field, set_block_group) now handle fields which store in split fields on ext4's on-disk format. For example, the superblock fields s_blocks_count and s_blocks_count_hi. The user can either set the low or high part of the field via "blocks_count_lo" or "blocks_count_hi", or both parts can be set via "blocks_count". Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* libext2fs: add metadata checksum and snapshot feature flagsTheodore Ts'o2011-09-161-0/+4
| | | | | | | | | | | | | | | | | | Reserve EXT4_FEATURE_RO_COMPAT_METADATA_CSUM and EXT2_FEATURE_COMPAT_EXCLUDE_BITMAP. Also reserve fields in the superblock and the inode for the checksums. In the block group descriptor, reserve the exclude bitmap field for the snapshot feature, and checksums for the inode and block allocation bitmaps. With this commit, the metadata checksum and exclude bitmap features should have reserved all of the fields they need in ext4's on-disk format. This commit also fixes an a missing byte swap for s_overhead_blocks. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: Darrick J. Wong <djwong@us.ibm.com> Cc: Amir Goldstein <amir73il@gmail.com>

* Add support for EXT2_FEATURE_COMPAT_LAZY_BGTheodore Ts'o2006-05-081-0/+2
| | | | | | | | | | | | | | This feature is initially intended for testing purposes; it allows an ext2/ext3 developer to create very large filesystems using sparse files where most of the block groups are not initialized and so do not require much disk space. Eventually it could be used as a way of speeding up mke2fs and e2fsck for large filesystem, but that would be best done by adding an RO_COMPAT extension to the filesystem to allow the inode table to be lazily initialized on a per-block basis, instead of being entirely initialized or entirely unused on a per-blockgroup basis.
