* resize2fs: correctly account for clusters when calculating summary statsTheodore Ts'o2013-01-191-13/+24

* libext2fs: teach the ext2fs_*_block_bitmap_range2() about clustersTheodore Ts'o2013-01-191-0/+30
| | | | | | | | | | | | | | | | | | | The ext2fs_{mark,unmark,test}_block_bitmap2() functions understand about clusters, and will take block numbers and convert them to clusters before checking the bitmap. The ext2fs_*_block_bitmap_range2() functions did not do this, which made them inconsistent. Fortunately, nothing has depended on this incorrect behavior, and in fact most of the usage of these functions have only recently been added, and only for optimizations that were only enabled for non-bigalloc file systems. So this is a change in previously exported functions, but (a) it doesn't change the behavior at all for non-bigalloc file systems, and (b) the change is more likely to fix bugs for bigalloc file systems. For example, this change fixes a problem with resize2fs and bigalloc file systems. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| | | | | | | | | | | | | | Add support for symbolic links using a new symlink command. Modeled after the do_mkdir() command. Testing demonstrates both fastlinks and slowlinks work correctly. Very long target paths fail as the command parsing appears to truncate the input to somewhere around 256 bytes.

* libext2fs: add the ext2fs_symlink() functionDarren Hart2013-01-164-0/+171
| | | | | | | | | | | | | | | | | | | | | | | | Creating symlinks is a complex affair when accounting for slowlinks. Create a new function, ext2fs_symlink(), modeled after ext2fs_mkdir(). Like ext2fs_mkdir(), ext2fs_symlink() takes on the task of allocating a new inode and block (for slowlinks), setting up sane default values in the inode, copying the target path to either the inode (for fastlinks) or to the first block (for slowlinks), and accounting for the inode and block stats. Disallow link targets longer than blocksize as the Linux kernel prevents this. It does not attempt to expand the parent directory, instead returning EXT2_ET_DIR_NO_SPACE and leaving it to the caller to expand just as ext2fs_mkdir() does. Ideally, I think both of these functions should make a single attempt to expand the directory.

* libext2fs: avoid 32-bit overflow in ext2fs_initialize with a 512M cluster sizeTheodore Ts'o2013-01-151-3/+12
| | | | | | | | | | | If the user attemps to create a 512MB cluster, we need to adjust the defaults to avoid a 32-bit overflow of s_blocks_per_group. Also check to make sure that the caller of ext2fs_initialize() has not given a value of s_clusters_per_group that would result in an overflow of s_blocks_per_group.

* mke2fs: require the bigalloc feature explicity if the cluster size is setZheng Liu2013-01-141-0/+5
| | | | | | | | | | | | When cluster-size is specified without the bigalloc feature, mke2fs will ignore this argument silently. But user might think bigalloc feature has been enabled unless they use the dumpe2fs command. So now we ask user to set bigalloc feature explicity when cluster-size is enabled. This can make sure that users understand what they are doing because bigalloc might impact the performance for some workloads.

* resize2fs: add debugging code to test the old online resizing interfacesTheodore Ts'o2013-01-141-2/+43
| | | | | | | | | | | | | | | | | | | | | | The old online resize ioctl interfaces are still present in the kernel, and we want to make it easy to test both the kernel code for those older interfaces, and resize2fs's use of those interfaces in a relatively easy manner. To do this, resize2fs will now check the environment variable RESIZE2FS_KERNEL_VERSION. If the version given is less than 3.3, then do not try using the new resizing ioctl, but instead use the resizing ioctls that were used before Linux version 3.3. If the version given is less than 3.7, then emulate sanity checks which get done to protect against the fact that the new resizing ioctl prior to 3.7 did not handle meta_bg resizing. (This was previously tested via the presence of the RESIZE2FS_NO_META_BG_RESIZE environment variable. But the new environment variable, RESIZE2FS_KERNEL_VERISON, is more general.)

* e2fsck: do not crash on long log file namesNickolai Zeldovich2013-01-081-6/+12
| | | | | | | | | | | | | Previously e2fsck would corrupt memory if the log file name was longer than 100 bytes (e.g., a long log_filename value in e2fsck.conf or a pattern that expands out to more than 100 bytes). This was due to incorrectly calling realloc() in append_string() on the struct string instead of the malloc'ed char* buffer, among other problems. This patch fixes the call to realloc() and also ensures that the buffer is grown by sufficiently many bytes (not just by 2x).
