* btrfs-progs: test: Add test image for btrfsck qgroup rescan detectionQu Wenruo2016-10-24
| | | | | | | | | | | Fixed by commit 7c646c538e74 btrfs-progs: qgroup: Fix regression leads to corrupted qgroup status. Add minimal test image for that fix. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> [ minor cleanups in test.sh ] Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: Fix stack overflow for checking qgroup on tree reloc treeQu Wenruo2016-10-24
| | | | | | | | | | | | | | | | | For tree reloc tree whose level is >= 2, the root node's parent will point to itself. In this case it will make btrfsck overflow its stack and cause segfault. While for tree reloc tree, it doesn't affect qgroup and kernel can handle it well. So add tree reloc tree check for qgroup-verify.c and fix the bug. Test case will follow soon after I make a minimal image for it. Current xz ziped image is still over 10M for a 512M fs.

* btrfs-progs: convert-test: Add test case for common inode flagsQu Wenruo2016-10-24
| | | | | | | | | Add a new test case to check if btrfs-convert copies common inode flags like append(a), immutable(i). Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> [ minor fixes ] Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: convert: Convert ext inode flags to btrfs inode flagsQu Wenruo2016-10-24
| | | | | | | | | | | | | | | Before this patch, btrfs-convert never copy ext* inode flags to corresponding btrfs inode flags. This makes common flags like APPEND/SYNC/SYNCDIR/IMMUTABLE not copied to btrfs inode. This patch introduces ext2_convert_inode_flags() function to handle the convert, so btrfs-convert can copy as many inode flags as possible.

* btrfs-progs: Make btrfs-debug-tree print all readable strings for inode flagsQu Wenruo2016-10-24
| | | | | | | | | | | | Before this patch, only 3 inode flags have readable string: NODATACOW, NODATASUM, READONLY. This patch will output all readable strings for remaining inode flags, making debug-tree tool more handy.

* btrfs-progs: test: add default ioctl-test buildDavid Sterba2016-10-24
| | | | | | | | Add another target that'll use default compiler options, eg. if we don't know the bitness of the architecture or gcc does not recognize the -m32/-m64 options. Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: tests: make the ioctl-test actually usefulDavid Sterba2016-10-24

* btrfs-progs: ioctl: add 64bit compat for SENDDavid Sterba2016-10-24
| | | | | | | | | | | | | | | | The ioctl value of SEND will be different on 32bit userspace and 64bit kernel due to different pointer type width, that unfortunatelly made it into the structure definition. To maintain backward compatibility, we must do it in the 64bit->32bit way, because we don't have the kernel side workardound like SET_RECEIVED_SUBVOL has. Changing value of SEND would then break existing users of the raw ioctl. The compatibility structure and ioctl should not be used, exists for documentation, and testing.

* btrfs-progs: ioctl: add 32bit compat for SET_RECEIVED_SUBVOLDavid Sterba2016-10-24
| | | | | | | | | | | | The ioctl value of SET_RECEIVED_SUBVOL will be different on 32bit userspace and 64bit kernel. This is transparently handled on the kernel side. We now define the same structure so we can verify the ioctl value. The defined structure and ioctl should not be used. It is exists only for testing purposes, documenting the mess and as a warning for the future. Signed-off-by: David Sterba <dsterba@suse.com>

This leads to wrong slot[0] and read_qgroup_status() will read out wrong flags, leading to regression. Fix read_qgroup_status() by using eb and slot instread of wrong path strucutre.
