* btrfs-progs: convert/ext2: Fix memory leak caused by handled ext2_filsysQu Wenruo2018-02-14
| | | | | | | | | | | | | Exposed by convert-test with D=asan. Unlike btrfs, ext2fs_close() still leaves its ext2_filsys parameter filled with allocated pointers. It needs ext2fs_free() to free those pointers. Issue: #92 Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: Sync code with kernel for BTRFS_MAX_INLINE_DATA_SIZEGu Jinxiang2018-02-02
| | | | | | | | | | | | | Do a cleanup. Also make it consistent with kernel. Use fs_info instead of root for BTRFS_MAX_INLINE_DATA_SIZE, since maybe in some situation we do not know root, but just know fs_info. Change macro to inline function to be consistent with kernel. And change the function body to match kernel. Signed-off-by: Gu Jinxiang <gujx@cn.fujitsu.com> Reviewed-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: convert: don't print message when fs is not recognized, ext2David Sterba2017-09-08
| | | | | | | Bad magic error means it's not the desired filesystem so the error message is just noise. Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: add crude error handling when transaction start failsDavid Sterba2017-09-08
| | | | | | | | | | Currently transaction bugs out insided btrfs_start_transaction in case of error, we want to lift the error handling to the callers. This patch adds the BUG_ON anywhere it's been missing so far. This is not the best way of course. Transforming BUG_ON to a proper error handling highly depends on the caller and should be dealt with case by case. Signed-off-by: David Sterba <dsterba@suse.com>

* Btrfs-progs: convert: do not clear nodatasum flag in inode itemLiu Bo2017-06-30
| | | | | | | | | With the current btrfs-convert, if we convert a ext4 without data checksum, it'd not set nodatasum flag in inode item, nor create csum item, reading file ends up with checksum errors. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: convert: Add larger device supportLakshmipathi.G2017-06-26
| | | | | | | | | | | | | | | | With larger file system (in this case its 22TB), ext2fs_open() returns EXT2_ET_CANT_USE_LEGACY_BITMAPS error message with ext2fs_read_block_bitmap(). To overcome this issue, (a) we need pass EXT2_FLAG_64BITS flag with ext2fs_open. (b) use 64-bit functions like ext2fs_get_block_bitmap_range2, ext2fs_inode_data_blocks2,ext2fs_read_ext_attr2 (c) use 64bit types with btrfs_convert_context fields Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=194795 Signed-off-by: Lakshmipathi.G <lakshmipathi.g@giis.co.in> Signed-off-by: David Sterba <dsterba@suse.com>
