[ Upstream commit af8c53c8bc087459b1aadd4c94805d8272358d79 ]
If userspace asked fsmap to try to count the number of entries, we cannot
return more than UINT_MAX entries because fmh_entries is u32.
Therefore, stop counting if we hit this limit or else we will waste time
to return truncated results.

[ Upstream commit 377254b2cd2252c7c3151b113cbdf93a7736c2e9 ]
If a device is hot-removed --- for example, when a physical device is
unplugged from pcie slot or a nbd device's network is shutdown ---
this can result in a BUG_ON() crash in submit_bh_wbc(). This is
because the when the block device dies, the buffer heads will have
their Buffer_Mapped flag get cleared, leading to the crash in
submit_bh_wbc.
We had attempted to work around this problem in commit a17712c8
("ext4: check superblock mapped prior to committing"). Unfortunately,
it's still possible to hit the BUG_ON(!buffer_mapped(bh)) if the
device dies between when the work-around check in ext4_commit_super()
and when submit_bh_wbh() is finally called:

To address this, add the check of 'buffer_mapped(bh)' to
__sync_dirty_buffer(). This also has the benefit of fixing this for
other file systems.
With this addition, we can drop the workaround in ext4_commit_supper().

When remounting filesystem fails late during remount handling and
block_validity mount option is also changed during the remount, we fail
to restore system zone information to a state matching the mount option.
This is mostly harmless, just the block validity checking will not match
the situation described by the mount option. Make sure these two are always
consistent.

[ Upstream commit f25391ebb475d3ffb3aa61bb90e3594c841749ef ]
Currently there is a problem with mount options that can be both set by
vfs using mount flags or by a string parsing in ext4.
i_version/iversion options gets lost after remount, for example
$ mount -o i_version /dev/pmem0 /mnt
$ grep pmem0 /proc/self/mountinfo | grep i_version
310 95 259:0 / /mnt rw,relatime shared:163 - ext4 /dev/pmem0 rw,seclabel,i_version
$ mount -o remount,ro /mnt
$ grep pmem0 /proc/self/mountinfo | grep i_version
nolazytime gets ignored by ext4 on remount, for example
$ mount -o lazytime /dev/pmem0 /mnt
$ grep pmem0 /proc/self/mountinfo | grep lazytime
310 95 259:0 / /mnt rw,relatime shared:163 - ext4 /dev/pmem0 rw,lazytime,seclabel
$ mount -o remount,nolazytime /mnt
$ grep pmem0 /proc/self/mountinfo | grep lazytime
310 95 259:0 / /mnt rw,relatime shared:163 - ext4 /dev/pmem0 rw,lazytime,seclabel
Fix it by applying the SB_LAZYTIME and SB_I_VERSION flags from *flags to
s_flags before we parse the option and use the resulting state of the
same flags in *flags at the end of successful remount.

[ Upstream commit 11215630aada28307ba555a43138db6ac54fa825 ]
A customer has reported a BUG_ON in ext4_clear_journal_err() hitting
during an LTP testing. Either this has been caused by a test setup
issue where the filesystem was being overwritten while LTP was mounting
it or the journal replay has overwritten the superblock with invalid
data. In either case it is preferable we don't take the machine down
with a BUG_ON. So handle the situation of unexpectedly missing
has_journal feature more gracefully. We issue warning and fail the mount
in the cases where the race window is narrow and the failed check is
most likely a programming error. In cases where fs corruption is more
likely, we do full ext4_error() handling before failing mount / remount.

[ Upstream commit bf9a379d0980e7413d94cb18dac73db2bfc5f470 ]
Currently, add_system_zone() just silently merges two added system zones
that overlap. However the overlap should not happen and it generally
suggests that some unrelated metadata overlap which indicates the fs is
corrupted. We should have caught such problems earlier (e.g. in
ext4_check_descriptors()) but add this check as another line of defense.
In later patch we also use this for stricter checking of journal inode
extent tree.

[ Upstream commit 5872331b3d91820e14716632ebb56b1399b34fe1 ]
If for any reason a directory passed to do_split() does not have enough
active entries to exceed half the size of the block, we can end up
iterating over all "count" entries without finding a split point.
In this case, count == move, and split will be zero, and we will
attempt a negative index into map[].
Guard against this by detecting this case, and falling back to
split-to-half-of-count instead; in this case we will still have
plenty of space (> half blocksize) in each split block.

ext4_check_dir_entry() with proper constraints that could result in
accepting corrupted directory entry as well as false positive filesystem

Change-Id: Icd6c8647a1a5c49b44b9280d9a947f2af6b450db
This patch is used to fix ext4 direct I/O read error when
the read size is not aligned with block size.
Then, I will use a test to explain the error.
(1) Make a file that is not aligned with block size:
$dd if=/dev/zero of=./test.jar bs=1000 count=3
(2) I wrote a source file named "direct_io_read_file.c" as following:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/file.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <string.h>
#define BUF_SIZE 1024
int main()
{
int fd;
int ret;
unsigned char *buf;
ret = posix_memalign((void **)&buf, 512, BUF_SIZE);
if (ret) {
perror("posix_memalign failed");
exit(1);
}
fd = open("./test.jar", O_RDONLY | O_DIRECT, 0755);
if (fd < 0){
perror("open ./test.jar failed");
exit(1);
}
do {
ret = read(fd, buf, BUF_SIZE);
printf("ret=%d\n",ret);
if (ret < 0) {
perror("write test.jar failed");
}
} while (ret > 0);
free(buf);
close(fd);
}
(3) Compile the source file:
$gcc direct_io_read_file.c -D_GNU_SOURCE
(4) Run the test program:
$./a.out
The result is as following:
ret=1024
ret=1024
ret=952
ret=-1
write test.jar failed: Invalid argument.
I have tested this program on XFS filesystem, XFS does not have
this problem, because XFS use iomap_dio_rw() to do direct I/O
read. And the comparing between read offset and file size is done
in iomap_dio_rw(), the code is as following:
if (pos < size) {
retval = filemap_write_and_wait_range(mapping, pos,
pos + iov_length(iov, nr_segs) - 1);
if (!retval) {
retval = mapping->a_ops->direct_IO(READ, iocb,
iov, pos, nr_segs);
}
...
}
...only when "pos < size", direct I/O can be done, or 0 will be return.
I have tested the fix patch on Ext4, it is up to the mustard of
EINVAL in man2(read) as following:
#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);
EINVAL
fd is attached to an object which is unsuitable for reading;
or the file was opened with the O_DIRECT flag, and either the
address specified in buf, the value specified in count, or the
current file offset is not suitably aligned.
So I think this patch can be applied to fix ext4 direct I/O error.
However Ext4 introduces direct I/O read using iomap infrastructure
on kernel 5.5, the patch is commit <b1b4705d54ab>
("ext4: introduce direct I/O read using iomap infrastructure"),
then Ext4 will be the same as XFS, they all use iomap_dio_rw() to do direct
I/O read. So this problem does not exist on kernel 5.5 for Ext4.
>From above description, we can see this problem exists on all the kernel
versions between kernel 3.14 and kernel 5.4. It will cause the Applications
to fail to read. For example, when the search service downloads a new full
index file, the search engine is loading the previous index file and is
processing the search request, it can not use buffer io that may squeeze
the previous index file in use from pagecache, so the serch service must
use direct I/O read.
Please apply this patch on these kernel versions, or please use the method
on kernel 5.5 to fix this problem.

[ Upstream commit 829b37b8cddb1db75c1b7905505b90e593b15db1 ]
Trying to change dax mount options when remounting could allow mount
options to be enabled for a small amount of time, and then the mount
option change would be reverted.
In the case of "mount -o remount,dax", this can cause a race where
files would temporarily treated as DAX --- and then not.

[ Upstream commit cfb3c85a600c6aa25a2581b3c1c4db3460f14e46 ]
Fix the bug when calculating the physical block number of the first
block in the split extent.
This bug will cause xfstests shared/298 failure on ext4 with bigalloc
enabled occasionally. Ext4 error messages indicate that previously freed
blocks are being freed again, and the following fsck will fail due to
the inconsistency of block bitmap and bg descriptor.
The following is an example case:
1. First, Initialize a ext4 filesystem with cluster size '16K', block size
'4K', in which case, one cluster contains four blocks.
2. Create one file (e.g., xxx.img) on this ext4 filesystem. Now the extent
tree of this file is like:
...
36864:[0]4:220160
36868:[0]14332:145408
51200:[0]2:231424
...
3. Then execute PUNCH_HOLE fallocate on this file. The hole range is
like:
..
ext4_ext_remove_space: dev 254,16 ino 12 since 49506 end 49506 depth 1
ext4_ext_remove_space: dev 254,16 ino 12 since 49544 end 49546 depth 1
ext4_ext_remove_space: dev 254,16 ino 12 since 49605 end 49607 depth 1
...
4. Then the extent tree of this file after punching is like
...
49507:[0]37:158047
49547:[0]58:158087
...
5. Detailed procedure of punching hole [49544, 49546]
5.1. The block address space:
```
lblk ~49505 49506 49507~49543 49544~49546 49547~
---------+------+-------------+----------------+--------
extent | hole | extent | hole | extent
---------+------+-------------+----------------+--------
pblk ~158045 158046 158047~158083 158084~158086 158087~
```
5.2. The detailed layout of cluster 39521:
```
cluster 39521
<------------------------------->
hole extent
<----------------------><--------
lblk 49544 49545 49546 49547
+-------+-------+-------+-------+
| | | | |
+-------+-------+-------+-------+
pblk 158084 1580845 158086 158087
```
5.3. The ftrace output when punching hole [49544, 49546]:
- ext4_ext_remove_space (start 49544, end 49546)
- ext4_ext_rm_leaf (start 49544, end 49546, last_extent [49507(158047), 40], partial [pclu 39522 lblk 0 state 2])
- ext4_remove_blocks (extent [49507(158047), 40], from 49544 to 49546, partial [pclu 39522 lblk 0 state 2]
- ext4_free_blocks: (block 158084 count 4)
- ext4_mballoc_free (extent 1/6753/1)
5.4. Ext4 error message in dmesg:
EXT4-fs error (device vdb): mb_free_blocks:1457: group 1, block 158084:freeing already freed block (bit 6753); block bitmap corrupt.
EXT4-fs error (device vdb): ext4_mb_generate_buddy:747: group 1, block bitmap and bg descriptor inconsistent: 19550 vs 19551 free clusters
In this case, the whole cluster 39521 is freed mistakenly when freeing
pblock 158084~158086 (i.e., the first three blocks of this cluster),
although pblock 158087 (the last remaining block of this cluster) has
not been freed yet.
The root cause of this isuue is that, the pclu of the partial cluster is
calculated mistakenly in ext4_ext_remove_space(). The correct
partial_cluster.pclu (i.e., the cluster number of the first block in the
next extent, that is, lblock 49597 (pblock 158086)) should be 39521 rather
than 39522.

Matching names with casefolded encrypting directories requires
decrypting entries to confirm case since we are case preserving. We can
avoid needing to decrypt if our hash values don't match.

Bug: 138322712
Change-Id: Id6024fc2a3bbde1e46a29070981fa64b3f667075
This adds support for encryption with casefolding.
Since the name on disk is case preserving, and also encrypted, we can no
longer just recompute the hash on the fly. Additionally, to avoid
leaking extra information from the hash of the unencrypted name, we use
siphash via an fscrypt v2 policy.
The hash is stored at the end of the directory entry for all entries
inside of an encrypted and casefolded directory apart from those that
deal with '.' and '..'. This way, the change is backwards compatible
with existing ext4 filesystems.

commit 08adf452e628b0e2ce9a01048cfbec52353703d7 upstream.
'igrab(d_inode(dentry->d_parent))' without holding dentry->d_lock is
broken because without d_lock, d_parent can be concurrently changed due
to a rename(). Then if the old directory is immediately deleted, old
d_parent->inode can be NULL. That causes a NULL dereference in igrab().
To fix this, use dget_parent() to safely grab a reference to the parent
dentry, which pins the inode. This also eliminates the need to use
d_find_any_alias() other than for the initial inode, as we no longer
throw away the dentry at each step.
This is an extremely hard race to hit, but it is possible. Adding a
udelay() in between the reads of ->d_parent and its ->d_inode makes it
reproducible on a no-journal filesystem using the following program:
#include <fcntl.h>
#include <unistd.h>
int main()
{
if (fork()) {
for (;;) {
mkdir("dir1", 0700);
int fd = open("dir1/file", O_RDWR|O_CREAT|O_SYNC);
write(fd, "X", 1);
close(fd);
}
} else {
mkdir("dir2", 0700);
for (;;) {
rename("dir1/file", "dir2/file");
rmdir("dir1");
}
}
}

commit 8418897f1bf87da0cb6936489d57a4320c32c0af upstream.
Don't pass error pointers to brelse().
commit 7159a986b420 ("ext4: fix some error pointer dereferences") has fixed
some cases, fix the remaining one case.
Once ext4_xattr_block_find()->ext4_sb_bread() failed, error pointer is
stored in @bs->bh, which will be passed to brelse() in the cleanup
routine of ext4_xattr_set_handle(). This will then cause a NULL panic
crash in __brelse().
BUG: unable to handle kernel NULL pointer dereference at 000000000000005b

commit c36a71b4e35ab35340facdd6964a00956b9fef0a upstream.
If eh->eh_max is 0, EXT_MAX_EXTENT/INDEX would evaluate to unsigned
(-1) resulting in illegal memory accesses. Although there is no
consistent repro, we see that generic/019 sometimes crashes because of
this bug.
Ran gce-xfstests smoke and verified that there were no regressions.

The only use of I_DIRTY_TIME_EXPIRE is to detect in
__writeback_single_inode() that inode got there because flush worker
decided it's time to writeback the dirty inode time stamps (either
because we are syncing or because of age). However we can detect this
directly in __writeback_single_inode() and there's no need for the
strange propagation with I_DIRTY_TIME_EXPIRE flag.

v1 encryption policies are deprecated in favor of v2, and some new
features (e.g. encryption+casefolding) are only being added for v2.
Therefore, the "test_dummy_encryption" mount option (which is used for
encryption I/O testing with xfstests) needs to support v2 policies.
To do this, extend its syntax to be "test_dummy_encryption=v1" or
"test_dummy_encryption=v2". The existing "test_dummy_encryption" (no
argument) also continues to be accepted, to specify the default setting
-- currently v1, but the next patch changes it to v2.
To cleanly support both v1 and v2 while also making it easy to support
specifying other encryption settings in the future (say, accepting
"$contents_mode:$filenames_mode:v2"), make ext4 and f2fs maintain a
pointer to the dummy fscrypt_context rather than using mount flags.
To avoid concurrency issues, don't allow test_dummy_encryption to be set
or changed during a remount. (The former restriction is new, but
xfstests doesn't run into it, so no one should notice.)
Tested with 'gce-xfstests -c {ext4,f2fs}/encrypt -g auto'. On ext4,
there are two regressions, both of which are test bugs: ext4/023 and
ext4/028 fail because they set an xattr and expect it to be stored
inline, but the increase in size of the fscrypt_context from
24 to 40 bytes causes this xattr to be spilled into an external block.

With the existing fscrypt IV generation methods, each file's data blocks
have contiguous DUNs. Therefore the direct I/O code "just worked"
because it only submits logically contiguous bios. But with
IV_INO_LBLK_32, the direct I/O code breaks because the DUN can wrap from
0xffffffff to 0. We can't submit bios across such boundaries.
This is especially difficult to handle when block_size != PAGE_SIZE,
since in that case the DUN can wrap in the middle of a page. Punt on
this case for now and just handle block_size == PAGE_SIZE.
Add and use a new function fscrypt_dio_supported() to check whether a
direct I/O request is unsupported due to encryption constraints.
Then, update fs/direct-io.c (used by f2fs, and by ext4 in kernel v5.4
and earlier) and fs/iomap/direct-io.c (used by ext4 in kernel v5.5 and
later) to avoid submitting I/O across a DUN discontinuity.
(This is needed in ACK now because ACK already supports direct I/O with
inline crypto. I'll be sending this upstream along with the encrypted
direct I/O support itself once its prerequisites are closer to landing.)
(cherry picked from android-mainline commit
8d6c90c9d68b985fa809626d12f8c9aff3c9dcb1)
Conflicts:
fs/ext4/file.c
fs/iomap/direct-io.c
(Dropped the iomap changes because in kernel v5.4 and earlier,
ext4 doesn't use iomap for direct I/O)
Test: For now, just manually tested direct I/O on ext4 and f2fs in the
DUN discontinuity case.

[ Upstream commit 907ea529fc4c3296701d2bfc8b831dd2a8121a34 ]
If the in-core buddy bitmap gets corrupted (or out of sync with the
block bitmap), issue a WARN_ON and try to recover. In most cases this
involves skipping trying to allocate out of a particular block group.
We can end up declaring the file system corrupted, which is fair,
since the file system probably should be checked before we proceed any
further.

Current wait times have proven to be too short to protect against inode
reuses that lead to metadata inconsistencies.
Now that we will retry the inode allocation if we can't find any
recently deleted inodes, it's a lot safer to increase the recently
deleted time from 5 seconds to a minute.

[ Upstream commit 4068664e3cd2312610ceac05b74c4cf1853b8325 ]
Extents are cached in read_extent_tree_block(); as a result, extents
are not cached for inodes with depth == 0 when we try to find the
extent using ext4_find_extent(). The result of the lookup is cached
in ext4_map_blocks() but is only a subset of the extent on disk. As a
result, the contents of extents status cache can get very badly
fragmented for certain workloads, such as a random 4k read workload.

Fix this by caching the extents for inodes with depth == 0 in
ext4_find_extent().
[ Renamed ext4_es_cache_extents() to ext4_cache_extents() since this
newly added function is not in extents_cache.c, and to avoid
potential visual confusion with ext4_es_cache_extent(). -TYT ]

[ Upstream commit c96e2b8564adfb8ac14469ebc51ddc1bfecb3ae2 ]
Under some circumstances we may encounter a filesystem error on a
read-only block device, and if we try to save the error info to the
superblock and commit it, we'll wind up with a noisy error and
backtrace, i.e.:
[ 3337.146838] EXT4-fs error (device pmem1p2): ext4_get_journal_inode:4634: comm mount: inode #0: comm mount: iget: illegal inode #

WARNING: CPU: 107 PID: 115347 at block/blk-core.c:788 generic_make_request_checks+0x6b4/0x7d0
...
To avoid this, commit the error info in the superblock only if the
block device is writable.

commit d87f639258a6a5980183f11876c884931ad93da2 upstream.
Since commit a8ac900b81 ("ext4: use non-movable memory for the
superblock") buffers for ext4 superblock were allocated using
the sb_bread_unmovable() helper which allocated buffer heads
out of non-movable memory blocks. It was necessarily to not block
page migrations and do not cause cma allocation failures.
However commit 85c8f176a6 ("ext4: preload block group descriptors")
broke this by introducing pre-reading of the ext4 superblock.
The problem is that __breadahead() is using __getblk() underneath,
which allocates buffer heads out of movable memory.
It resulted in page migration failures I've seen on a machine
with an ext4 partition and a preallocated cma area.
Fix this by introducing sb_breadahead_unmovable() and
__breadahead_gfp() helpers which use non-movable memory for buffer
head allocations and use them for the ext4 superblock readahead.

commit 801674f34ecfed033b062a0f217506b93c8d5e8a upstream.
We do not want to create initialized extents beyond end of file because
for e2fsck it is impossible to distinguish them from a case of corrupted
file size / extent tree and so it complains like:
Inode 12, i_size is 147456, should be 163840. Fix? no
Code in ext4_ext_convert_to_initialized() and
ext4_split_convert_extents() try to make sure it does not create
initialized extents beyond inode size however they check against
inode->i_size which is wrong. They should instead check against
EXT4_I(inode)->i_disksize which is the current inode size on disk.
That's what e2fsck is going to see in case of crash before all dirty
data is written. This bug manifests as generic/456 test failure (with
recent enough fstests where fsx got fixed to properly pass
FALLOC_KEEP_SIZE_FL flags to the kernel) when run with dioread_lock
mount option.
