Zhihao Cheng 2dc49f58a2 ubifs: Rectify space amount budget for mkdir/tmpfile operations
[ Upstream commit a6dab6607d4681d227905d5198710b575dbdb519 ]

UBIFS should make sure the flash has enough space to store dirty (Data
that is newer than disk) data (in memory), space budget is exactly
designed to do that. If space budget calculates less data than we need,
'make_reservation()' will do more work(return -ENOSPC if no free space
lelf, sometimes we can see "cannot reserve xxx bytes in jhead xxx, error
-28" in ubifs error messages) with ubifs inodes locked, which may effect
other syscalls.

A simple way to decide how much space do we need when make a budget:
See how much space is needed by 'make_reservation()' in ubifs_jnl_xxx()
function according to corresponding operation.

It's better to report ENOSPC in ubifs_budget_space(), as early as we can.

Baokun Li 8a0c70c238 ubifs: rename_whiteout: correct old_dir size computing
commit 705757274599e2e064dd3054aabc74e8af31a095 upstream.

When renaming the whiteout file, the old whiteout file is not deleted.
Therefore, we add the old dentry size to the old dir like XFS.
Otherwise, an error may be reported due to `fscki->calc_sz != fscki->size`
in check_indes.

Zhihao Cheng 13b2a8151e ubifs: Add missing iput if do_tmpfile() failed in rename whiteout
commit 716b4573026bcbfa7b58ed19fe15554bac66b082 upstream.

whiteout inode should be put when do_tmpfile() failed if inode has been
initialized. Otherwise we will get following warning during umount:
  UBIFS error (ubi0:0 pid 1494): ubifs_assert_failed [ubifs]: UBIFS
  assert failed: c->bi.dd_growth == 0, in fs/ubifs/super.c:1930
  VFS: Busy inodes after unmount of ubifs. Self-destruct in 5 seconds.

Zhihao Cheng 83e42a7842 ubifs: Fix deadlock in concurrent rename whiteout and inode writeback

, are caused by concurrent rename whiteout and inode writeback processes:

ubifs_rename
  do_rename
    lock_4_inodes (Hold ui_mutex)

					            LOCK(ui_mutex)
							   ↑
	      wb_wait_for_completion (Wait wb work) <-- deadlock!

Reproducer (Detail program in [Link]):
  1. SYS_renameat2("/mp/dir/file", "/mp/dir/whiteout", RENAME_WHITEOUT)
  2. Consume out of space before kernel(mdelay) doing budget for whiteout

Fix it by doing whiteout space budget before locking ubifs inodes.
BTW, it also fixes wrong goto tag 'out_release' in whiteout budget
error handling path(It should at least recover dir i_size and unlock
4 ubifs inodes).

Zhihao Cheng a90e2dbe66 ubifs: rename_whiteout: Fix double free for whiteout_ui->data
commit 40a8f0d5e7b3999f096570edab71c345da812e3e upstream.

'whiteout_ui->data' will be freed twice if space budget fail for
rename whiteout operation as following process:

rename_whiteout
  dev = kmalloc
  whiteout_ui->data = dev
  kfree(whiteout_ui->data)  // Free first time
  iput(whiteout)
    ubifs_free_inode
      kfree(ui->data)	    // Double free!

Let ubifs_free_inode() free 'whiteout_ui->data'. BTW, delete unused
assignment 'whiteout_ui->data_len = 0', process 'ubifs_evict_inode()
-> ubifs_jnl_delete_inode() -> ubifs_jnl_write_inode()' doesn't need it
(because 'inc_nlink(whiteout)' won't be excuted by 'goto out_release',
 and the nlink of whiteout inode is 0).

Eric Biggers 4af7c34103 fscrypt: introduce fscrypt_prepare_readdir()
The last remaining use of fscrypt_get_encryption_info() from filesystems
is for readdir (->iterate_shared()).  Every other call is now in
fs/crypto/ as part of some other higher-level operation.

We need to add a new argument to fscrypt_get_encryption_info() to
indicate whether the encryption policy is allowed to be unrecognized or
not.  Doing this is easier if we can work with high-level operations
rather than direct filesystem use of fscrypt_get_encryption_info().

So add a function fscrypt_prepare_readdir() which wraps the call to
fscrypt_get_encryption_info() for the readdir use case.

Eric Biggers c247d00ee0 ubifs: remove ubifs_dir_open()
Since encrypted directories can be opened and searched without their key
being available, and each readdir and ->lookup() tries to set up the
key, trying to set up the key in ->open() too isn't really useful.

Just remove it so that directories don't need an ->open() method
anymore, and so that we eliminate a use of fscrypt_get_encryption_info()
(which I'd like to stop exporting to filesystems).

Eric Biggers cfdfa25f08 ubifs: prevent creating duplicate encrypted filenames
As described in "fscrypt: add fscrypt_is_nokey_name()", it's possible to
create a duplicate filename in an encrypted directory by creating a file
concurrently with adding the directory's encryption key.

Fix this bug on ubifs by rejecting no-key dentries in ubifs_create(),
ubifs_mkdir(), ubifs_mknod(), and ubifs_symlink().

Note that ubifs doesn't actually report the duplicate filenames from
readdir, but rather it seems to replace the original dentry with a new
one (which is still wrong, just a different effect from ext4).

On ubifs, this fixes xfstest generic/595 as well as the new xfstest I
wrote specifically for this bug.

Daniel Rosenberg 39c8e0ea66 fscrypt: Have filesystems handle their d_ops
This shifts the responsibility of setting up dentry operations from
fscrypt to the individual filesystems, allowing them to have their own
operations while still setting fscrypt's d_revalidate as appropriate.

Most filesystems can just use generic_set_encrypted_ci_d_ops, unless
they have their own specific dentry operations as well. That operation
will set the minimal d_ops required under the circumstances.

Since the fscrypt d_ops are set later on, we must set all d_ops there,
since we cannot adjust those later on. This should not result in any
change in behavior.

Convert ubifs to use the new functions fscrypt_prepare_new_inode() and
fscrypt_set_context().

Unlike ext4 and f2fs, this doesn't appear to fix any deadlock bug.  But
it does shorten the code slightly and get all filesystems using the same
helper functions, so that fscrypt_inherit_context() can be removed.

It also fixes an incorrect error code where ubifs returned EPERM instead
of the expected ENOKEY.

Kees Cook 3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

Eric Biggers aec992aab8 ubifs: allow both hash and disk name to be provided in no-key names
In order to support a new dirhash method that is a secret-keyed hash
over the plaintext filenames (which will be used by encrypted+casefolded
directories on ext4 and f2fs), fscrypt will be switching to a new no-key
name format that always encodes the dirhash in the name.

UBIFS isn't happy with this because it has assertions that verify that
either the hash or the disk name is provided, not both.

Change it to use the disk name if one is provided, even if a hash is
available too; else use the hash.

If userspace provides an invalid fscrypt no-key filename which encodes a
hash value with any of the UBIFS node type bits set (i.e. the high 3
bits), gracefully report ENOENT rather than triggering ubifs_assert().

Test case with kvm-xfstests shell:

    dev=$(__blkdev_to_ubi_volume /dev/vdc)
    ubiupdatevol $dev -t
    mount $dev /mnt -t ubifs
    mkdir /mnt/edir
    xfs_io -c set_encpolicy /mnt/edir
    rm /mnt/edir/_,,,,,DAAAAAAAAAAAAAAAAAAAAAAAAAA

With the bug, the following assertion fails on the 'rm' command:

    [   19.066048] UBIFS error (ubi0:0 pid 379): ubifs_assert_failed: UBIFS assert failed: !(hash & ~UBIFS_S_KEY_HASH_MASK), in fs/ubifs/key.h:170

shouldn't change any behavior since the flags are kept in sync.

Richard Weinberger 9ca2d73264 ubifs: Limit number of xattrs per inode
Since we have to write one deletion inode per xattr
into the journal, limit the max number of xattrs.

In theory UBIFS supported up to 65535 xattrs per inode.
But this never worked correctly, expect no powercuts happened.
Now we support only as many xattrs as we can store in 50% of a
LEB.
Even for tiny flashes this allows dozens of xattrs per inode,
which is for an embedded filesystem still fine.

In case someone has existing inodes with much more xattrs, it is
still possible to delete them.
UBIFS will fall back to an non-atomic deletion mode.

Eric Biggers c64cda8a99 ubifs: remove unnecessary calls to set up directory key
In ubifs_unlink() and ubifs_rmdir(), remove the call to
fscrypt_get_encryption_info() that precedes fscrypt_setup_filename().
This call was unnecessary, because fscrypt_setup_filename() already
tries to set up the directory's encryption key.

Eric Biggers b01531db6c fscrypt: fix race where ->lookup() marks plaintext dentry as ciphertext
->lookup() in an encrypted directory begins as follows:

1. fscrypt_prepare_lookup():
    a. Try to load the directory's encryption key.
    b. If the key is unavailable, mark the dentry as a ciphertext name
       via d_flags.
2. fscrypt_setup_filename():
    a. Try to load the directory's encryption key.
    b. If the key is available, encrypt the name (treated as a plaintext
       name) to get the on-disk name.  Otherwise decode the name
       (treated as a ciphertext name) to get the on-disk name.

But if the key is concurrently added, it may be found at (2a) but not at
(1a).  In this case, the dentry will be wrongly marked as a ciphertext
name even though it was actually treated as plaintext.

This will cause the dentry to be wrongly invalidated on the next lookup,
potentially causing problems.  For example, if the racy ->lookup() was
part of sys_mount(), then the new mount will be detached when anything
tries to access it.  This is despite the mountpoint having a plaintext
path, which should remain valid now that the key was added.

Of course, this is only possible if there's a userspace race.  Still,
the additional kernel-side race is confusing and unexpected.

Close the kernel-side race by changing fscrypt_prepare_lookup() to also
set the on-disk filename (step 2b), consistent with the d_flags update.

This aids in reliability testing, especially since some xattr

Also an embedded system might not need it, so this allows for a

Linus Torvalds 7a932516f5 vfs/y2038: inode timestamps conversion to timespec64
This is a late set of changes from Deepa Dinamani doing an automated
 treewide conversion of the inode and iattr structures from 'timespec'
 to 'timespec64', to push the conversion from the VFS layer into the
 individual file systems.
 
 There were no conflicts between this and the contents of linux-next
 until just before the merge window, when we saw multiple problems:
 
 - A minor conflict with my own y2038 fixes, which I could address
   by adding another patch on top here.
 - One semantic conflict with late changes to the NFS tree. I addressed
   this by merging Deepa's original branch on top of the changes that
   now got merged into mainline and making sure the merge commit includes
   the necessary changes as produced by coccinelle.
 - A trivial conflict against the removal of staging/lustre.
 - Multiple conflicts against the VFS changes in the overlayfs tree.
   These are still part of linux-next, but apparently this is no longer
   intended for 4.18 [1], so I am ignoring that part.
 
 As Deepa writes:
 
   The series aims to switch vfs timestamps to use struct timespec64.
   Currently vfs uses struct timespec, which is not y2038 safe.
 
   The series involves the following:
   1. Add vfs helper functions for supporting struct timepec64 timestamps.
   2. Cast prints of vfs timestamps to avoid warnings after the switch.
   3. Simplify code using vfs timestamps so that the actual
      replacement becomes easy.
   4. Convert vfs timestamps to use struct timespec64 using a script.
      This is a flag day patch.
 
   Next steps:
   1. Convert APIs that can handle timespec64, instead of converting
      timestamps at the boundaries.
   2. Update internal data structures to avoid timestamp conversions.
 
 Thomas Gleixner adds:
 
   I think there is no point to drag that out for the next merge window.
   The whole thing needs to be done in one go for the core changes which
   means that you're going to play that catchup game forever. Let's get
   over with it towards the end of the merge window.

Deepa Dinamani 95582b0083 vfs: change inode times to use struct timespec64
struct timespec is not y2038 safe. Transition vfs to use
y2038 safe struct timespec64 instead.

The change was made with the help of the following cocinelle
script. This catches about 80% of the changes.
All the header file and logic changes are included in the
first 5 rules. The rest are trivial substitutions.
I avoid changing any of the function signatures or any other
filesystem specific data structures to keep the patch simple
for review.

The script can be a little shorter by combining different cases.
But, this version was sufficient for my usecase.

  from the fscrypt tree. This will end up dropping the kzalloc() ->

  fine"

Richard Weinberger a02a6eba99 ubifs: Wire-up statx() support
statx() can report what flags a file has, expose flags that UBIFS
supports. Especially STATX_ATTR_COMPRESSED and STATX_ATTR_ENCRYPTED
can be interesting for userspace.

David Gstir f34e87f58d ubifs: Don't encrypt special files on creation
When a new inode is created, we check if the containing folder has a encryption
policy set and inherit that. This should however only be done for regular
files, links and subdirectories. Not for sockes fifos etc.

Deepa Dinamani 607a11ad94 fs: ubifs: replace CURRENT_TIME_SEC with current_time
CURRENT_TIME_SEC is not y2038 safe.  current_time() will be transitioned
to use 64 bit time along with vfs in a separate patch.  There is no plan
to transition CURRENT_TIME_SEC to use y2038 safe time interfaces.

current_time() returns timestamps according to the granularities set in
the inode's super_block.  The granularity check to call
current_fs_time() or CURRENT_TIME_SEC is not required.

Use current_time() directly to update inode timestamp.  Use
timespec_trunc during file system creation, before the first inode is
created.

Eric Biggers 413d5a9edb ubifs: check for consistent encryption contexts in ubifs_lookup()
As ext4 and f2fs do, ubifs should check for consistent encryption
contexts during ->lookup() in an encrypted directory.  This protects
certain users of filesystem encryption against certain types of offline
attacks.

Richard Weinberger 32fe905c17 ubifs: Fix O_TMPFILE corner case in ubifs_link()
It is perfectly fine to link a tmpfile back using linkat().
Since tmpfiles are created with a link count of 0 they appear
on the orphan list, upon re-linking the inode has to be removed
from the orphan list again.

Ralph faced a filesystem corruption in combination with overlayfs
due to this bug.
