Remove btrfs_qgroup_inherit_add_copy() and the command line interface.

This was designed to add a pair of source/destination qgroups into
btrfs_qgroup_inherit structure, so that rfer/excl numbers would be
copied from the source qgroup into the destination one.

This behavior has been intentionally hidden since 2016, as such copy will
cause qgroup inconsistent immediately and a rescan would reset whatever
numbers copied anyway.

Now we're going to reject the copy behavior from kernel, there is no
need to keep those hidden (and already disabled for "subvolume create")
case.

Remove btrfs_qgroup_inherit_add_copy() call, and cleanup the
undocumented options.

[BUG]
With the latest kernel patch to reject invalid qgroupids in
btrfs_qgroup_inherit structure, "btrfs subvolume create" or "btrfs
subvolume snapshot" can lead to the following output:

 # mkfs.btrfs -O quota -f $dev
 # mount $dev $mnt
 # btrfs subvolume create -i 2/0 $mnt/subv1
 Create subvolume '/mnt/btrfs/subv1'
 ERROR: cannot create subvolume: No such file or directory

The "btrfs subvolume" command output the first line, seemingly to
indicate a successful subvolume creation, then followed by an error
message.

This can be a little confusing on whether if the subvolume is created or
not.

[FIX]
Fix the output by only outputting the regular line if the ioctl
succeeded.

The initial version of libbtrfsutil did not follow a unified naming
scheme that's usually used for libraries like those provide by
util-linux. Add aliases that are "btrfs_util_" + object + action +
suffix.

The library version changes to 1.3 but there's no new functionality,
only the aliases added. New functions can be added in the future without
possible confusion when the same action could apply to different
objects.

Add wrappers around v1 and v2 of TREE_SEARCH ioctl so it can be
transparently used by code. The structures partially overlap but due to
the buffer size the v2 is offset and also needs a filler to expand the
flexible buffer.

Usage:

- define struct btrfs_tree_search_args, all zeros
- btrfs_tree_search_sk() reads offset of the search key within the
  structures
- btrfs_tree_search_ioctl() detect support and call the highest
  supported ioctl version, v2 has been supported since 3.14 but we want
  to keep backward compatibility
- btrfs_tree_search_data() read data from the buffer previously filled
  by ioctl, a sequence of (search header, data)

Signed-off-by: David Sterba <[email protected]>
For unclear reasons using the v2 ioctl leads to an infinite loop in
'btrfs fi usage' in load_chunk_info() when there's only one valid item
returned and then it keeps looping. Can be reproduced by mkfs-tests/001.

After debugging, from second item in the buffer there's all zeros, while
it's returned nr_items=4. Switching the same code to use v1 makes it
work again. It's puzzling as it's the same code in kernel.

We want to make the switch eventually so only disable the detection so
other code can use the new API.

Signed-off-by: David Sterba <[email protected]>
Use tree search ioctl wrappers for code that is considered internal, ie.
leaving out libbtrfs (legacy), libbtrfsutil (needs own API for that).

Conversion is mostly direct of what the API provides.

The filename sanitization is not recommended as it introduces mismatches
between DIR_ITEM and INODE_REF.

Even hash collision mode (double "-s" option) is not ensured to always
find a hash collision, and when fails to find one, a mismatch happens.

And when a mismatch happens, the kernel will not resolve the path
correctly since kernel uses the hash from DIR_ITEM to lookup the child
inode.

So add a warning into the "-s" option of btrfs-image.

[BUG]
There is a bug report that image dump taken by "btrfs-image -s" doesn't
really sanitize the filenames:

  # truncates -s 1G source.raw
  # mkfs.btrfs -f source.raw
  # mount source.raw $mnt
  # touch $mnt/top_secret_filename
  # touch $mnt/secret_filename
  # umount $mnt
  # btrfs-image -s source.raw dump.img
  # string dump.img | grep filename
  top_secret_filename
  secret_filename
  top_secret_filename
  secret_filename
  top_secret_filename

[CAUSE]
Using above image to store the fs, and we got the following result in fs
tree:

	item 0 key (256 INODE_ITEM 0) itemoff 16123 itemsize 160
		generation 3 transid 7 size 68 nbytes 16384
		block group 0 mode 40755 links 1 uid 0 gid 0 rdev 0
		sequence 2 flags 0x0(none)
	item 1 key (256 INODE_REF 256) itemoff 16111 itemsize 12
		index 0 namelen 2 name: ..
	item 2 key (256 DIR_ITEM 439756795) itemoff 16062 itemsize 49
		location key (257 INODE_ITEM 0) type FILE
		transid 7 data_len 0 name_len 19
		name: top_secret_filename
	item 3 key (256 DIR_ITEM 693462946) itemoff 16017 itemsize 45
		location key (258 INODE_ITEM 0) type FILE
		transid 7 data_len 0 name_len 15
		name: secret_filename
	item 4 key (256 DIR_INDEX 2) itemoff 15968 itemsize 49
		location key (257 INODE_ITEM 0) type FILE
		transid 7 data_len 0 name_len 19
		name: top_secret_filename
	item 5 key (256 DIR_INDEX 3) itemoff 15923 itemsize 45
		location key (258 INODE_ITEM 0) type FILE
		transid 7 data_len 0 name_len 15
		name: secret_filename
	item 6 key (257 INODE_ITEM 0) itemoff 15763 itemsize 160
		generation 7 transid 7 size 0 nbytes 0
		block group 0 mode 100644 links 1 uid 0 gid 0 rdev 0
		sequence 1 flags 0x0(none)
	item 7 key (257 INODE_REF 256) itemoff 15734 itemsize 29
		index 2 namelen 19 name: top_secret_filename
	item 8 key (258 INODE_ITEM 0) itemoff 15574 itemsize 160
		generation 7 transid 7 size 0 nbytes 0
		block group 0 mode 100644 links 1 uid 0 gid 0 rdev 0
		sequence 1 flags 0x0(none)
	item 9 key (258 INODE_REF 256) itemoff 15549 itemsize 25
		index 3 namelen 15 name: 1���'�gc*&R

The result shows, only the last INODE_REF got sanitized, all the
remaining are not touched at all.

This is caused by how we sanitize the filenames:

 copy_buffer()
 |- memcpy(dst, src->data, src->len);
 |  This means we copy the whole eb into our buffer already.
 |
 |- zero_items()
    |- sanitize_name()
       |- eb = alloc_dummy_eb();
       |- memcpy(eb->data, src->data, src->len);
       |  This means we generate a dummy eb with the same contents of
       |  the source eb.
       |
       |- sanitize_dir_item();
       |  We override the dir item of the given item (specified by the
       |  slot number) inside our dummy eb.
       |
       |- memcpy(dst, eb->data, eb->lem);

The last one copy the dummy eb into our buffer, with only the slot
corrupted.

But when the whole work flow hits the next slot, we only corrupt the
next slot, but still copy the whole dummy eb back to buffer.

This means the previous slot would be overwritten by the old unsanitized
data.

Resulting only the last slot is corrupted.

[FIX]
Fix the bug by only copying back the corrupted item to the buffer.
So that other slots won't be overwritten by unsanitized data.

[BUG]
When rolling back a converted btrfs, the filename output is corrupted:

  $ btrfs-convert -r  ~/test.img
  btrfs-convert from btrfs-progs v6.9.2

  Open filesystem for rollback:
    Label:
    UUID:            df54baf3-c91e-4956-96f9-99413a857576
    Restoring from:  ext2_saved0ƨy/image
                               ^^^ Corruption
  Rollback succeeded

[CAUSE]
The error is in how we handle the filename.  In btrfs all our strings
are not '\0' terminated, but with explicit length.

But in C, most strings are '\0' terminated, so after reading a filename
from btrfs, we need to manually terminate the string.

However the code adding the terminating '\0' looks like this:

	/* Get the filename length. */
	name_len = btrfs_root_ref_name_len(path.nodes[0], root_ref_item);

	/*
	 * This should not happen, but as an extra handling for possible
	 * corrupted btrfs.
	 */
	if (name_len > sizeof(dir_name))
		name_len = sizeof(dir_name) - 1;
	/* Got the real filename into our buffer. */
 	read_extent_buffer(path.nodes[0], dir_name, (unsigned long)(root_ref_item + 1), name_len);

	/* Terminate the string. */
	dir_name[sizeof(dir_name) - 1] = 0;

The problem is, the final termination is totally wrong, it always make
the last buffer char '\0', not using the @name_len we read before.

[FIX]
Use @name_len to terminate the string, as we have already updated it to
handle buffer overflow, it can handle both the regular and corrupted
case.

The new new test case is to make sure the rollback output for a fixed
content converted fs contains the string "ext2_saved/image".

As we have a bug in the past where after the string "ext2_saved", we can
have some unterminated garbage.

For "btrfstune --csum", currently we do the following operations in just
one transaction for each:

- Delete old data csums
- Change new data csums objectid

Both operation can modify up to GiB or even TiB level of metadata, doing
them in just one transaction is definitely going to cause problems.

This patch adds a leaf number based threshold (32 leaves), after
modifying/deleting this many leaves, we commit a transaction to avoid
huge amount of dirty leaves piling up.

Python 3.13, currently in beta, removed the internal
_PyObject_LookupSpecial function. The libbtrfsutil Python bindings use
it in the path_converter() function because it was based on internal
path_converter() function in CPython [1]. This is causing build failures
on Fedora Rawhide [2] and Gentoo [3]. Replace path_converter() with a
version that only uses public functions based on the one in drgn [4].

…onvert

Currently mkfs uses its own create_uuid_tree(), but that function is
only handling FS_TREE.  This means for btrfs-convert we do not generate
the uuid tree, nor add the UUID of the image subvolume.  This can be a
problem if we're going to support multiple subvolumes during mkfs time.

To address this, introduce a new helper, btrfs_rebuild_uuid_tree():

- Create a new uuid tree if there is not one

- Remove all the existing items from uuid tree

- Iterate through all subvolumes
  * If the subvolume has no valid UUID, regenerate one
  * Add the uuid entry for the subvolume UUID
  * If the subvolume has received UUID, also add it to UUID tree

By this, this new helper can handle all the uuid tree generation needs for:

- Current mkfs
  Only one uuid entry for FS_TREE

- Current btrfs-convert
  Only FS_TREE and the image subvolume

- Future multi-subvolume mkfs
  As we do the scan for all subvolumes.

- Future "btrfs rescue rebuild-uuid-tree"

Commit d7492ec ("btrfs-progs: use on-stack buffer in
__ino_to_path_fd") was supposed to switch path buffer from dynamic
allocation to on-stack but it was done wrong. The btrfs_data_container
is a flexible array so it needs to be explicitly allocated to the right
size.

The conversion turned it to an array. Gcc 13.x started to warn about
access to fspath->val[i] being out of bounds. Fortunately overall size
was 65536 and used only first 4096 bytes.

toplevel qgroup.

It's caused by the fact that we called qgroups_search_all() but didn't
do any cleanup.

[FIX]
Call __free_all_qgroups() inside cmd_qgroup_clear_stale() to properly
free the qgroups.

The thread sanitizer finds race conditions and in the past did find
some bugs. There's not much threaded code, it's namely the progress
tracking in btrfs-convert so the coverage is slightly redundant. Add it
just in case.

It is possible to create swapfile on a multi-device filesystem but it's
not reliable. The check that verifies that in kernel:

10698                 } else if (device != map->stripes[0].dev) {
10699                         btrfs_warn(fs_info, "swapfile must be on one device");
10700                         ret = -EINVAL;
10701                         goto out;
10702                 }

This does not count devices but rather the actual placement of the
swapfile extents, so multi-device filesystem with single profile can
create it as long as there's enough space and the allocator decides to
place it properly.

Make it more visible what the result of snapshotted subvolume is. This
partially duplicates the other section.

The sysfs file description is hard to find. Also link to btrfs(5) from
administration.

The page is not complete but mentions at least NFS, cgroups and
fsverity.
