c4190ca330 btrfs-progs: ci: do apt-get update before trying to install
To ensure that package indexes are up to date.

That should help to avoid recent failed CI runs, which failed to install
certain packages as local cache is out-of-date and remote mirrors no
longer provide that specific (and out-of-date) version of package:

9ad15a7301 btrfs-progs: use btrfs_link_subvolume() to replace btrfs_mksubvol()
The function btrfs_mksubvol() is very different between btrfs-progs and
kernel, the former version is really just linking a subvolume to another
directory inode, but the kernel version is really to make a completely
new subvolume.

Instead of same-named function, introduce btrfs_link_subvolume() and use
it to replace the old btrfs_mksubvol().

This is done by:

- Introduce btrfs_link_subvolume()
  Which does extra checks before doing any modification:
  * Make sure the target inode is a directory
  * Make sure no filename conflict

  Then do the linkage:
  * Add the dir_item/dir_index into the parent inode
  * Add the forward and backward root refs into tree root

- Introduce link_image_subvolume() helper
  Currently btrfs_mksubvol() has a dedicated convert filename retry
  behavior, which is unnecessary and should be done by the convert code.

  Now move the filename retry behavior into the helper.

- Remove btrfs_mksubvol()
  Since there is only one caller utilizing btrfs_mksubvol(), and it's
  now gone, we can remove the old btrfs_mksubvol().

3c555beabf btrfs-progs: introduce btrfs_make_subvolume()
There are two different subvolume/data reloc tree creation routines:

- create_subvol() from convert/main.c
  * calls btrfs_copy_root() to create an empty root
    This is not safe, as it relies on the source root to be empty.
  * calls btrfs_read_fs_root() to add it to the cache and trace it
    properly
  * calls btrfs_make_root_dir() to initialize the empty new root

- create_data_reloc_tree() from mkfs/main.c
  * calls btrfs_create_tree() to create an empty root
  * Manually add the root to fs_root cache
    This is only safe for data reloc tree as it's never updated
    inside btrfs-progs.
    But not safe for other subvolume trees.
  * manually setup the root dir

Both have their good and bad aspects, so here we introduce a new helper,
btrfs_make_subvolume():

- Calls btrfs_create_tree() to create an empty root
- Calls btrfs_read_fs_root() to setup the cache and tracking properly
- Calls btrfs_make_root_dir() to initialize the root dir
- Calls btrfs_update_root() to reflect the rootdir change

So this new helper can replace both create_subvol() and
create_data_reloc_tree().

9fdb8d7469 btrfs-progs: add uClibc-ng compatibility for printf format %pV
Commit [1] 164bc10d "btrfs-progs: add musl compatibility for printf
format %pV" added a logic to detect the presence of the glibc
<printf.h> header, and if present, to use the
register_printf_specifier() and register_printf_modifier() functions.

The original intent (as the commit log suggests), was to support the
musl libc, which does not provides this <printf.h> header.

When compiling with another libc, such as uClibc-ng, btrfs-progs fail
to build with error:

    common/messages.c: In function 'print_va_format':
    common/messages.c:51:19: error: 'const struct printf_info' has no member named 'user'
       51 |         if (!(info->user & va_modifier))
          |                   ^~
    common/messages.c: In function 'btrfs_no_printk':
    common/messages.c:76:17: warning: implicit declaration of function 'register_printf_specifier'; did you mean 'register_printf_function'? [-Wimplicit-function-declaration]
       76 |                 register_printf_specifier('V', print_va_format,
          |                 ^~~~~~~~~~~~~~~~~~~~~~~~~
          |                 register_printf_function
    common/messages.c:78:31: warning: implicit declaration of function 'register_printf_modifier'; did you mean 'register_printf_function'? [-Wimplicit-function-declaration]
       78 |                 va_modifier = register_printf_modifier(L"p");
          |                               ^~~~~~~~~~~~~~~~~~~~~~~~
          |                               register_printf_function

This is because uClibc-ng provides a <printf.h> header, but not the
register_printf_specifier() and register_printf_modifier() functions.
See [2]. It mainly includes register_printf_function(). uClibc-ng
emulates an older glibc behavior. Glibc added support for printf user
elements in commit [3] (first included in glibc-2.10, in 2009). Checking
only the <printf.h> is not sufficient.

This commit fixes this build issue by refining the detection logic of
the <printf.h> functions required by btrfs-progs.

61e7ade17e btrfs-progs: kerncompat: fix fallthrough definition for gcc 5.x and 6.x.
Commit [1] 3a1d4aa089 "btrfs-progs: fix fallthrough cases with proper
attributes" introduced a macro "fallthrough" to better handle compiler
warnings of fallthrough situations.

This macro is defined using the "__has_attribute" built-in
function-like macro, which was introduced in GCC 5. See [2]. It then
test for the "__fallthrough__" attribute, which was introduced in
GCC 7. See [3].

When compiling with a gcc version which supports "__has_attribute" and
not the "__fallthrough__" attribute, compilation fails with error
message:

    common/format-output.c: In function 'print_escaped':
    common/format-output.c:78:4: error: 'fallthrough' undeclared (first use in this function)
        fallthrough;
        ^
btrfs-progs claim to support gcc at minimal version 4.8 in [4].

This commit fixes this issue by adding the missing definition.

The definition of the unsupported case is duplicated, because testing
for "__has_attribute" and an attribute at the same time is not
portable. See the cpp "__has_attribute" documentation [5].

Note: the issue was found with Buildroot Linux [6], while testing with
the command "utils/test-pkg -a -p btrfs-progs".

There's another workflow with the same goal but based on different

db2cd62f2c btrfs-progs: inspect list-chunks: better sorting, updated output
Enhance the sorting capabilities of 'inspect list-chunks' to allow
multiple keys. Drop the gaps, this works only for pstart and it's hard
to make it work with arbitrary sort keys.

Usage is printed by default, assuming this is an interesting info and
even if it slows down the output (due to extra lookups) it's more
convenient to print it rather than not.

The options related to usage and empty were removed.

Output changes:

- rename Number to PNumber, meaning physical number on the device
- print Devid, device number, can be also sort key

Examples:

btrfs inspect list-chunks /mnt
btrfs inspect list-chunks --sort length,usage
btrfs inspect list-chunks --sort lstart

Depending on the sort key order, the output can be wild, for that the
PNumber and LNumber give some hint where the chunks lie in their space.

Example output:

$ sudo ./btrfs inspect list-chunks --sort length,usage /
Devid PNumber      Type/profile    PStart    Length      PEnd LNumber    LStart Usage%

e3e10fc8c6 libbtrfsutil: fix accidentally closing fd passed to subvolume iterator
For an unprivileged subvolume iterator, append_to_search_stack() closes
cur_fd. On the first call to btrfs_util_subvolume_iterator_next(),
cur_fd is equal to the fd that was passed to
btrfs_util_create_subvolume_iterator_fd(). We're not supposed to close
that. We didn't notice it because it's more common to use it through
btrfs_util_create_subvolume_iterator(), which opens its own fd that
should be closed, and because the fd number is often reused internally
by the subvolume iterator.

pop_search_stack() already has a check to avoid closing the passed fd;
add the same check to append_to_search_stack(). Also add a regression
test.

4e95d7d028 btrfs-progs: do not check ram_bytes for non-compressed data extents
This patch reverts the following 3 commits:
d0cc40d23a ("btrfs-progs: tests: add test case for ram_bytes detection and repair")
7313573c19 ("btrfs-progs: check: original, detect and repair ram_bytes mismatch")
97bf7a5969 ("btrfs-progs: check: lowmem, detect and repair mismatched ram_bytes")

The problem with the ram_bytes check is, kernel can handle it without
any problem, and the original objective for this is to detect such
problem as I immaturelly believe the problem is fixed.

But it turns out to be incorrect and this check is already causing
problems.

Fix it by doing a full revert for now.

ed1c6b8c00 btrfs-progs: convert: copy whole xattr name buffer
Commit 4db925911c ("btrfs-progs: use strncpy_null everywhere")
replaced strncpy with strncpy_null, the maximum xattr name length is 255
(current limit), the target buffer is large enough for the whole size so
make sure the last character is also copied.

Remove the not needed encoding and reserved fields in struct
raid_stripe_extent.

This saves 8 bytes per stripe extent.

Note: this is a format change and previously created filesystems with
raid-stripe-tree will not be accessible. Similar patch is needed in
kernel.

5887ea343f btrfs-progs: change-csum: fix the wrong metadata space reservation
[BUG]
'btrfstune --csum' would always fail for a newly created btrfs:

  # truncate -s 1G test.img
  # ./mkfs.btrfs -f test.img
  # ./btrsftune --csum xxhash test.img
  WARNING: Experimental build with unstable or unfinished features
  WARNING: Switching checksums is experimental, do not use for valuable data!

  Proceed to switch checksums
  ERROR: failed to start transaction: Unknown error -28
  ERROR: failed to start transaction: No space left on device
  ERROR: failed to generate new data csums: No space left on device
  ERROR: btrfstune failed

[CAUSE]
After commit e79f18a4a7 ("btrfs-progs: introduce a basic metadata free
space reservation check"), btrfs_start_transaction() would check the
metadata space.

But at the time of introduction of csum conversion, the parameter for
btrfs_start_transaction() was incorrect.

The 2nd parameter is the *number* of items to be added (if we're
deleting items, just pass 1).
However commit 08a3bd7694 ("btrfs-progs: tune: add the ability to
generate new data checksums") is using the item size, not the number of
items to be added.

This means we're passing a number 8 * nodesize times larger than the
original size, no wonder we would error out with -ENOSPC.

[FIX]
Use proper calcuation to convert the new csum item size to number of
leaves needed, and double it just in case.
