2016-12-16ovl: check for emptiness of redirect dirAmir Goldstein1-9/+22
Before introducing redirect_dir feature, the condition !ovl_lower_positive(dentry) for a directory, implied that it is a pure upper directory, which may be removed if empty. Now that directory can be redirect, it is possible that upper does not cover any lower (i.e. !ovl_lower_positive(dentry)), but the directory is a merge (with redirected path) and maybe non empty. Check for this case in ovl_remove_upper(). This change fixes the following test case from rename-pop-dir.py of unionmount-testsuite: """Remove dir and rename old name""" d = ctx.non_empty_dir() d2 = ctx.no_dir() ctx.rmdir(d, err=ENOTEMPTY) ctx.rename(d, d2) ctx.rmdir(d, err=ENOENT) ctx.rmdir(d2, err=ENOTEMPTY) ./run --ov rename-pop-dir /mnt/a/no_dir103: Expected error (Directory not empty) was not produced Signed-off-by: Amir Goldstein <[email protected]> Signed-off-by: Miklos Szeredi <[email protected]>
2016-12-16ovl: redirect on rename-dirMiklos Szeredi7-30/+195
Current code returns EXDEV when a directory would need to be copied up to move. We could copy up the directory tree in this case, but there's another, simpler solution: point to old lower directory from moved upper directory. This is achieved with a "trusted.overlay.redirect" xattr storing the path relative to the root of the overlay. After such attribute has been set, the directory can be moved without further actions required. This is a backward incompatible feature, old kernels won't be able to correctly mount an overlay containing redirected directories. Signed-off-by: Miklos Szeredi <[email protected]>
2016-12-16ovl: lookup redirectsMiklos Szeredi4-2/+123
If a directory has the "trusted.overlay.redirect" xattr, it means that the value of the xattr should be used to find the underlying directory on the next lower layer. The redirect may be relative or absolute. Absolute redirects begin with a slash. A relative redirect means: instead of the current dentry's name use the value of the redirect to find the directory in the next lower layer. Relative redirects must not contain a slash. An absolute redirect means: look up the directory relative to the root of the overlay using the value of the redirect in the next lower layer. Redirects work on lower layers as well.

2016-12-16ovl: fix nested overlayfs mountAmir Goldstein1-2/+2
When the upper overlayfs checks "trusted.overlay.*" xattr on the underlying overlayfs mount, it gets -EPERM, which confuses the upper overlayfs. Fix this by returning -EOPNOTSUPP instead of -EPERM from ovl_own_xattr_get() and ovl_own_xattr_set(). This behavior is consistent with the behavior of ovl_listxattr(), which filters out the private overlayfs xattrs. Note: nested overlays are deprecated. But this change makes sense regardless: these xattrs are private to the overlay and should always be hidden. Hence getting and setting them should indicate this. [SzMi: Use EOPNOTSUPP instead of ENODATA and use it for both getting and setting "trusted.overlay." xattrs. This is a perfectly valid error code for "we don't support this prefix", which is the case here.] Signed-off-by: Amir Goldstein <[email protected]> Signed-off-by: Miklos Szeredi <[email protected]>

2016-12-16ovl: simplify lookupMiklos Szeredi1-29/+25
If encountering a non-directory, then stop looking at lower layers. In this case the oe->opaque flag is not set anymore, which doesn't matter since existence of lower file is now checked at remove/rename time. Signed-off-by: Miklos Szeredi <[email protected]>
2016-12-16ovl: check lower existence of rename targetMiklos Szeredi1-52/+11
Check if something exists on the lower layer(s) under the target or rename to decide if directory needs to be marked "opaque". Marking opaque is done before the rename, and on failure the marking was undone. Also the opaque xattr was removed if the target didn't cover anything. This patch changes behavior so that removal of "opaque" is not done in either of the above cases. This means that directory may have the opaque flag even if it doesn't cover anything. However this shouldn't affect the performance or semantics of the overalay, while simplifying the code. Signed-off-by: Miklos Szeredi <[email protected]>

2016-12-16ovl: check lower existence when removingMiklos Szeredi3-3/+56
Currently ovl_lookup() checks existence of lower file even if there's a non-directory on upper (which is always opaque). This is done so that remove can decide whether a whiteout is needed or not. It would be better to defer this check to unlink, since most of the time the gathered information about opaqueness will be unused. This adds a helper ovl_lower_positive() that checks if there's anything on the lower layer(s). The following patches also introduce changes to how the "opaque" attribute is updated on directories: this attribute is added when the directory is creted or moved over a whiteout or object covering something on the lower layer. However following changes will allow the attribute to remain on the directory after being moved, even if the new location doesn't cover anything. Because of this, we need to check lower layers even for opaque directories, so that whiteout is only created when necessary. This function will later be also used to decide about marking a directory opaque, so deal with negative dentries as well. When dealing with negative, it's enough to check for being a whiteout If the dentry is positive but not upper then it also obviously needs whiteout/opaque.

2016-12-16ovl: use vfs_clone_file_range() for copy up if possibleAmir Goldstein1-1/+8
When copying up within the same fs, try to use vfs_clone_file_range(). This is very efficient when lower and upper are on the same fs with file reflink support. If vfs_clone_file_range() fails for any reason, copy up falls back to the regular data copy code. Tested correct behavior when lower and upper are on: 1. same ext4 (copy) 2. same xfs + reflink patches + mkfs.xfs (copy) 3. same xfs + reflink patches + mkfs.xfs -m reflink=1 (reflink) 4. different xfs + reflink patches + mkfs.xfs -m reflink=1 (copy) For comparison, on my laptop, xfstest overlay/001 (copy up of large sparse files) takes less than 1 second in the xfs reflink setup vs. 25 seconds on the rest of the setups.

2016-12-16vfs: fix vfs_clone_file_range() for overlayfs filesAmir Goldstein1-5/+5
With overlayfs, it is wrong to compare file_inode(inode)->i_sb of regular files with those of non-regular files, because the former reference the real (upper/lower) sb and the latter reference the overlayfs sb. Move the test for same super block after the sanity tests for clone range of directory and non-regular file. This change fixes xfstest generic/157, which returned EXDEV instead of EISDIR/EINVAL in the following test cases over overlayfs: echo "Try to reflink a dir" _reflink_range $testdir1/dir1 0 $testdir1/file2 0 $blksz echo "Try to reflink a device" _reflink_range $testdir1/dev1 0 $testdir1/file2 0 $blksz Signed-off-by: Amir Goldstein <[email protected]> Signed-off-by: Miklos Szeredi <[email protected]>

FICLONE/FICLONERANGE ioctls return -EXDEV if src and dest files are not on the same mount point. Practically, clone only requires that src and dest files are on the same file system.
