2011-10-04libquota: use ext2_loff_t instead of loff_tTheodore Ts'o3-12/+16
The type loff_t is not portable. Use ext2_loff_t which handles this for us. Cc: Aditya Kali <adityakali@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-10-04libquota: remove get_qf_name()Theodore Ts'o5-22/+8
The get_qf_name() function used PATH_MAX, which is non-portable. Worse, it blindly assumed that PATH_MAX was the size of the buffer passed to it --- which in the one and only place where it was used in libquota, was a buffer declared to a fixed size 256 bytes. Fix this by simply getting rid of the function altogether. Cc: Aditya Kali <adityakali@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-10-04libquota: clean up some gcc -Wall warningsTheodore Ts'o9-65/+29
Remove unused variables, places where 'return' was used with no value in a non-void function, missing function declarations, etc. Don't assume that all systems have quotactl(), and use <sys/quota.h> if it exists to define the quotactl interfaces. One of the unused variables also got rid of a non-portable use of PATH_MAX. Cc: Aditya Kali <adityakali@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-10-04libquota: remove get_qf_path()Theodore Ts'o2-20/+0
This function isn't used anywhere, so remove it. It also uses PATH_MAX which is not portable. Cc: Aditya Kali <adityakali@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-10-03libext2fs: fix bad cast which causes problems for file systems > 512EBTheodore Ts'o1-1/+1
If the number of block groups exceeds 2**32, a bad cast would lead to a bogus "Not enough space to build proposed filesystem while setting up superblock" failure. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2011-10-03Add "big" and "huge" types to mke2fs.confTheodore Ts'o2-0/+12
mke2fs attempts to use the "big" and "huge" types, and now that mke2fs will complain if there are file system types which are undefined, let's add definitions for them. Thanks to Richard Jones for reporting this problem. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-10-03libext2fs: move #include "ext2fs.h" from crc32c_defs.h to crc32c.cTheodore Ts'o2-17/+17
The byte swap functions which are defined in ext2fs.h are only needed by crc32.c, and not by gen_crc32ctable.c. The gen_crc32ctable program needs to be compiled on the host OS, where ext2fs.h may not be present. So move the use of the header function to crc32c.c, to avoid compilation problems.

2011-10-03resize2fs: fix on-line resizingTheodore Ts'o1-4/+12
On-line resizing has been broken in the 1.42 series for two reasons: (a) the call to the new EXT4_IOC_RESIZE_FS ioctl checked for ENOTTY to indicate that the ioctl does not exist, when in fact EINVAL is what is returned if the ioctl doesn't exist. (b) resize2fs was passing in a pointer to a 64-bit value, when the ioctl expected a 32-bit value. This was OK on little-endian systems, but it wouldn't work at all on big-endian systems. Fix both problems. Addresses-Debian-Bug: #451388 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-09-30e2fsck: avoid unnecessary reboots in some cases when checking the root fsTheodore Ts'o4-19/+9
If e2fsck modifies certain superblock fields which the kernel doesn't look at, mark the superblock as dirty without marking the file system as changed. This will avoid e2fsck signalling the init scripts that a reboot is necessary. This is safe, because the kernel doesn't actually look at these superblock fields.

2011-09-30filefrag: Display the number of contiguous, not physical, extentsTheodore Ts'o1-6/+3
From a bug report filed by Ibragimov Rinat: When filefrag uses FIEMAP ioctl its logic differs for ordinary and verbose (-v) modes. ext4 returns extent on every 32768 block so on large files it is possible that `filefrag large-file' tells about 4 extents while `filefrag -v large-file' finds only one. Also when I tried to use generic_block_fiemap function to add FIEMAP for reiserfs, every block was reported as a new extent resulting in thousands "extents" for continuous files. I think filefrag should merge adjacent extents even when -v is not specified. Addresses-Debian-Bug: #631498 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-09-30libext2fs: Always swab the MMP block on big-endian systems machinesDarrick J. Wong1-9/+6
The MMP code in libext2fs tries to gate MMP block swab'ing with this test: if (fs->super->s_magic == ext2fs_swab16(EXT2_SUPER_MAGIC)) However, EXT2FS_ENABLE_SWAPFS never seems to be defined anywhere (all possible existed, the field fs->super->s_magic is always in host byteorder, so the test always fails. So, we can change the #ifdef to WORDS_BIGENDIAN (which is conditionally defined on BE platforms) and get rid of the broken if test. Signed-off-by: Darrick J.

2011-09-30e2fsck: zero ctx->fs after freeing fs when restarting due to MMPDarrick J. Wong1-0/+1
If MMP is enabled and e2fsck determines that it needs to restart itself on account of various MMP conditions, it will close the current fs and jump back to the start of fs checking. However, closing fs also frees it, which means that we need to set ctx->fs to NULL to prevent subsequent open code from accessing the old deleted pointer. Signed-off-by: Darrick J.

If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which is also the default), s_max_mnt_count needs to be set to -1, instead of 0. Kernels newer than 3.0 will interpret 0 to disable periodic checks, but older kernels will print a warning message on each mount, which will annoy users.

2011-09-25e2fsck: regression tests for INCOMPAT_MMP featureAndreas Dilger13-3/+292
Add tests for the MMP feature - creating a filesystem with mke2fs and MMP enabled, enable/disable MMP with tune2fs, disabling the e2fsck MMP flag with tune2fs after a failed e2fsck, and e2fsck checking and fixing a corrupt MMP block. The MMP tests need to be run from a real disk, not tmpfs, because tmpfs doesn't support O_DIRECT reads, which MMP uses to ensure that reads from the MMP block are not filled from the page cache. Using a local disk does not slow down the tests noticably, since they wait to detect if the MMP block is being modified.

2011-09-25ext2fs: add multi-mount protection (INCOMPAT_MMP)Andreas Dilger30-79/+1166
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.

Continue to remove the external journal device even if the device cannot be found. Add a test to verify that the journal device/UUID are actually removed from the superblock. It isn't possible to use a real journal device for testing without loopback devices and such (it must be a block device) and this would invite complexity and failures in the regression test.

2011-09-24libext2fs: add flag to ext2fs_flush() and ext2fs_close() to avoid fsyncRichard W.M. Jones3-3/+25
This adds new APIs: ext2fs_flush2 and ext2fs_close2 which take an extra 'int flags' parameter. This allows us to pass in an EXT2_FLAG_FLUSH_NO_SYNC flag which avoids fsync'ing the filesystem when closing it. For the case we have in mind where we are just constructing a throwaway ext2 filesystem in a file in order to boot a VM, this saves over 5 seconds during the boot process and avoids many unnecessary disk writes. Existing code using ext2fs_flush and ext2fs_close remains unaffected by this change. Signed-off-by: Richard W.M. Jones <rjones@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

2011-09-18Shorten compile commands run by the build systemTheodore Ts'o268-790/+1969
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>
