* Btrfs-progs: add fsck test for filesystem with shared prealloc extentsFilipe Manana2018-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Verify that a filesystem check operation (fsck) does not report the following scenario as an error: An extent is shared between two inodes, as a result of clone/reflink operation, and for one of the inodes, lets call it inode A, the extent is referenced through a file extent item as a prealloc extent, while for the other inode, call it inode B, the extent is referenced through a regular file extent item, that is, it was written to. The goal of this test is to make sure a filesystem check operation will not report "odd csum items" errors for the prealloc extent at inode A, because this scenario is valid since the extent was written through inode B and therefore it is expected to have checksum items in the filesystem's checksum btree for that shared extent. Such scenario can be created with the following steps for example: mkfs.btrfs -f /dev/sdb mount /dev/sdb /mnt touch /mnt/foo xfs_io -c "falloc 0 256K" /mnt/foo sync xfs_io -c "pwrite -S 0xab 0 256K" /mnt/foo touch /mnt/bar xfs_io -c "reflink /mnt/foo 0 0 256K" /mnt/bar xfs_io -c "fsync" /mnt/bar <power fail> mount /dev/sdb /mnt umount /mnt This scenario is fixed by the following patch for the filesystem checker: "Btrfs-progs: check, fix false error reports for shared prealloc extents" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

| | | | | | | | | | Move the testsuite to tests/ and make the tarball generation more deterministic.

* btrfs-progs: Add make testsuite command for export testsGu Jinxiang2018-02-13
| | | | | | | | | | | | | | | | | Export the testsuite files to a separate tar. Since fsck tests depend on btrfs-corrupt-block, and misc tests depends on both btrfs-corrupt-block and fssum, so set it as prerequisites for package commad. Because, althougth fssum can be generated by source that are all in tests directory, and has no rely on the btrfs's structure. But btrfs-corrupt-block deeply relys on btrfs's structure. For consistency, at the present stage, generete the two when create test tar.

* btrfs-progs: treewide: Replace strerror(errno) with %m.Rosen Penev2018-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As btrfs is specific to Linux, %m can be used instead of strerror(errno) in format strings. This has some size reduction benefits for embedded systems. glibc, musl, and uclibc-ng all support %m as a modifier to printf. A quick glance at the BIONIC libc source indicates that it has support for %m as well. BSDs and Windows do not but I do believe them to be beyond the scope of btrfs-progs.
