commit 4b654acdae850f48b8250b9a578a4eaa518c7a6f upstream.
In btrfs_read_block_groups(), if we have an invalid block group which
has mixed type (DATA|METADATA) while the fs doesn't have MIXED_GROUPS
feature, we error out without freeing the block group cache.
This patch will add the missing btrfs_put_block_group() to prevent
memory leak.
Note for stable backports: the file to patch in versions <= 5.3 is
fs/btrfs/extent-tree.c
Fixes: 49303381f19a ("Btrfs: bail out if block group has different mixed flag")

commit 03d9a9fe3f3aec508e485dd3dcfa1e99933b4bdb upstream.
According to MS-CIFS specification MID 0xFFFF should not be used by the
CIFS client, but we actually do. Besides, this has proven to cause races
leading to oops between SendReceive2/cifs_demultiplex_thread. On SMB1,
MID is a 2 byte value easy to reach in CurrentMid which may conflict with
an oplock break notification request coming from server

commit c9fbd7bbc23dbdd73364be4d045e5d3612cf6e82 upstream.
We recently had an oops reported on a 4.14 kernel in
xfs_reclaim_inodes_count() where sb->s_fs_info pointed to garbage
and so the m_perag_tree lookup walked into lala land.
Essentially, the machine was under memory pressure when the mount
was being run, xfs_fs_fill_super() failed after allocating the
xfs_mount and attaching it to sb->s_fs_info. It then cleaned up and
freed the xfs_mount, but the sb->s_fs_info field still pointed to
the freed memory. Hence when the superblock shrinker then ran
it fell off the bad pointer.
With the superblock shrinker problem fixed at teh VFS level, this
stale s_fs_info pointer is still a problem - we use it
unconditionally in ->put_super when the superblock is being torn
down, and hence we can still trip over it after a ->fill_super
call failure. Hence we need to clear s_fs_info if
xfs-fs_fill_super() fails, and we need to check if it's valid in
the places it can potentially be dereferenced after a ->fill_super
failure.

[ Upstream commit c82e5ac7fe3570a269c0929bf7899f62048e7dbc ]
Currently the client indicates that a dentry is stale when inode
numbers or type types between a local inode and a remote file
don't match. If this is the case attributes is not being copied
from remote to local, so, it is already known that the local copy
has stale metadata. That's why the inode needs to be marked for
revalidation in order to tell the VFS to lookup the dentry again
before openning a file. This prevents unexpected stale errors
to be returned to the user space when openning a file.

Commit 7196ac113a4f ("Fix to check Unique id and FileType when client
refer file directly.") checks whether the uniqueid of an inode has
changed when getting the inode info, but only when using the UNIX
extensions. Add a similar check for SMB2+, since this can be done
without an extra network roundtrip.

commit 0b3d0ef9840f7be202393ca9116b857f6f793715 upstream.
Mark inode for force revalidation if LOOKUP_REVAL flag is set.
This tells the client to actually send a QueryInfo request to
the server to obtain the latest metadata in case a directory
or a file were changed remotely. Only do that if the client
doesn't have a lease for the file to avoid unneeded round
trips to the server.

commit 30573a82fb179420b8aac30a3a3595aa96a93156 upstream.
Currently if the client identifies problems when processing
metadata returned in CREATE response, the open handle is being
leaked. This causes multiple problems like a file missing a lease
break by that client which causes high latencies to other clients
accessing the file. Another side-effect of this is that the file
can't be deleted.
Fix this by closing the file after the client hits an error after
the file was opened and the open descriptor wasn't returned to
the user space. Also convert -ESTALE to -EOPENSTALE to allow
the VFS to revalidate a dentry and retry the open.

[ Upstream commit 750670341a24cb714e624e0fd7da30900ad93752 ]
When filling an inode with info from the MDS, i_blkbits is being
initialized using fl_stripe_unit, which contains the stripe unit in
bytes. Unfortunately, this doesn't make sense for directories as they
have fl_stripe_unit set to '0'. This means that i_blkbits will be set
to 0xff, causing an UBSAN undefined behaviour in i_blocksize():
UBSAN: Undefined behaviour in ./include/linux/fs.h:731:12
shift exponent 255 is too large for 32-bit type 'int'
Fix this by initializing i_blkbits to CEPH_BLOCK_SHIFT if fl_stripe_unit
is zero.

[ Upstream commit c87a37ebd40b889178664c2c09cc187334146292 ]
Currently on mmap cache policy, we always attach writeback_fid
whether mmap type is SHARED or PRIVATE. However, in the use case
of kata-container which combines 9p(Guest OS) with overlayfs(Host OS),
this behavior will trigger overlayfs' copy-up when excute command
inside container.

[ Upstream commit e2751463eaa6f9fec8fea80abbdc62dbc487b3c5 ]
In encode_attrs(), there is an if statement on line 1145 to check
whether label is NULL:
if (label && (attrmask[2] & FATTR4_WORD2_SECURITY_LABEL))
When label is NULL, it is used on lines 1178-1181:
*p++ = cpu_to_be32(label->lfs);
*p++ = cpu_to_be32(label->pi);
*p++ = cpu_to_be32(label->len);
p = xdr_encode_opaque_fixed(p, label->label, label->len);
To fix these bugs, label is checked before being used.
These bugs are found by a static analysis tool STCheck written by us.

[ Upstream commit 0a3775e4f883912944481cf2ef36eb6383a9cc74 ]
There is a scenario causing ocfs2 umount hang when multiple hosts are
rebooting at the same time.
NODE1 NODE2 NODE3
send unlock requset to NODE2
dies
become recovery master
recover NODE2
find NODE2 dead
mark resource RECOVERING
directly remove lock from grant list
calculate usage but RECOVERING marked
**miss the window of purging
clear RECOVERING
To reproduce this issue, crash a host and then umount ocfs2
from another node.
To solve this, just let unlock progress wait for recovery done.

[ Upstream commit 07bfa4415ab607e459b69bd86aa7e7602ce10b4f ]
If userspace reads the buffer via blockdev while mounting,
sb_getblk()+modify can race with buffer read via blockdev.
For example,
FS userspace
bh = sb_getblk()
modify bh->b_data
read
ll_rw_block(bh)
fill bh->b_data by on-disk data
/* lost modified data by FS */
set_buffer_uptodate(bh)
set_buffer_uptodate(bh)
Userspace should not use the blockdev while mounting though, the udev
seems to be already doing this. Although I think the udev should try to
avoid this, workaround the race by small overhead.

[ Upstream commit 13fc1d271a2e3ab8a02071e711add01fab9271f6 ]
There is a race between setting up a qgroup rescan worker and completing
a qgroup rescan worker that can lead to callers of the qgroup rescan wait
ioctl to either not wait for the rescan worker to complete or to hang
forever due to missing wake ups. The following diagram shows a sequence
of steps that illustrates the race.
CPU 1 CPU 2 CPU 3
btrfs_ioctl_quota_rescan()
btrfs_qgroup_rescan()
qgroup_rescan_init()
mutex_lock(&fs_info->qgroup_rescan_lock)
spin_lock(&fs_info->qgroup_lock)
fs_info->qgroup_flags |=
BTRFS_QGROUP_STATUS_FLAG_RESCAN
init_completion(
&fs_info->qgroup_rescan_completion)
fs_info->qgroup_rescan_running = true
mutex_unlock(&fs_info->qgroup_rescan_lock)
spin_unlock(&fs_info->qgroup_lock)
btrfs_init_work()
--> starts the worker
btrfs_qgroup_rescan_worker()
mutex_lock(&fs_info->qgroup_rescan_lock)
fs_info->qgroup_flags &=
~BTRFS_QGROUP_STATUS_FLAG_RESCAN
mutex_unlock(&fs_info->qgroup_rescan_lock)
starts transaction, updates qgroup status
item, etc
btrfs_ioctl_quota_rescan()
btrfs_qgroup_rescan()
qgroup_rescan_init()
mutex_lock(&fs_info->qgroup_rescan_lock)
spin_lock(&fs_info->qgroup_lock)
fs_info->qgroup_flags |=
BTRFS_QGROUP_STATUS_FLAG_RESCAN
init_completion(
&fs_info->qgroup_rescan_completion)
fs_info->qgroup_rescan_running = true
mutex_unlock(&fs_info->qgroup_rescan_lock)
spin_unlock(&fs_info->qgroup_lock)
btrfs_init_work()
--> starts another worker
mutex_lock(&fs_info->qgroup_rescan_lock)
fs_info->qgroup_rescan_running = false
mutex_unlock(&fs_info->qgroup_rescan_lock)
complete_all(&fs_info->qgroup_rescan_completion)
Before the rescan worker started by the task at CPU 3 completes, if
another task calls btrfs_ioctl_quota_rescan(), it will get -EINPROGRESS
because the flag BTRFS_QGROUP_STATUS_FLAG_RESCAN is set at
fs_info->qgroup_flags, which is expected and correct behaviour.
However if other task calls btrfs_ioctl_quota_rescan_wait() before the
rescan worker started by the task at CPU 3 completes, it will return
immediately without waiting for the new rescan worker to complete,
because fs_info->qgroup_rescan_running is set to false by CPU 2.
This race is making test case btrfs/171 (from fstests) to fail often:
btrfs/171 9s ... - output mismatch (see /home/fdmanana/git/hub/xfstests/results//btrfs/171.out.bad)
# --- tests/btrfs/171.out 2018-09-16 21:30:48.505104287 +0100
# +++ /home/fdmanana/git/hub/xfstests/results//btrfs/171.out.bad 2019-09-19 02:01:36.938486039 +0100
# @@ -1,2 +1,3 @@
# QA output created by 171
# +ERROR: quota rescan failed: Operation now in progress
# Silence is golden
# ...
# (Run 'diff -u /home/fdmanana/git/hub/xfstests/tests/btrfs/171.out /home/fdmanana/git/hub/xfstests/results//btrfs/171.out.bad' to see the entire diff)
That is because the test calls the btrfs-progs commands "qgroup quota
rescan -w", "qgroup assign" and "qgroup remove" in a sequence that makes
calls to the rescan start ioctl fail with -EINPROGRESS (note the "btrfs"
commands 'qgroup assign' and 'qgroup remove' often call the rescan start
ioctl after calling the qgroup assign ioctl,
btrfs_ioctl_qgroup_assign()), since previous waits didn't actually wait
for a rescan worker to complete.
Another problem the race can cause is missing wake ups for waiters,
since the call to complete_all() happens outside a critical section and
after clearing the flag BTRFS_QGROUP_STATUS_FLAG_RESCAN. In the sequence
diagram above, if we have a waiter for the first rescan task (executed
by CPU 2), then fs_info->qgroup_rescan_completion.wait is not empty, and
if after the rescan worker clears BTRFS_QGROUP_STATUS_FLAG_RESCAN and
before it calls complete_all() against
fs_info->qgroup_rescan_completion, the task at CPU 3 calls
init_completion() against fs_info->qgroup_rescan_completion which
re-initilizes its wait queue to an empty queue, therefore causing the
rescan worker at CPU 2 to call complete_all() against an empty queue,
never waking up the task waiting for that rescan worker.
Fix this by clearing BTRFS_QGROUP_STATUS_FLAG_RESCAN and setting
fs_info->qgroup_rescan_running to false in the same critical section,
delimited by the mutex fs_info->qgroup_rescan_lock, as well as doing the
call to complete_all() in that same critical section. This gives the
protection needed to avoid rescan wait ioctl callers not waiting for a
running rescan worker and the lost wake ups problem, since setting that
rescan flag and boolean as well as initializing the wait queue is done
already in a critical section delimited by that mutex (at
qgroup_rescan_init()).
Fixes: 57254b6ebce4ce ("Btrfs: add ioctl to wait for qgroup rescan completion")
Fixes: d2c609b834d62f ("btrfs: properly track when rescan worker is running")

commit 6af112b11a4bc1b560f60a618ac9c1dcefe9836e upstream.
When doing any form of incremental send the parent and the child trees
need to be compared via btrfs_compare_trees. This can result in long
loop chains without ever relinquishing the CPU. This causes softlockup
detector to trigger when comparing trees with a lot of items. Example
report:

commit efad8a853ad2057f96664328a0d327a05ce39c76 upstream.
At ctree.c:get_old_root(), we are accessing a root's header owner field
after we have freed the respective extent buffer. This results in an
use-after-free that can lead to crashes, and when CONFIG_DEBUG_PAGEALLOC
is set, results in a stack trace like the following:

commit 5c2e9f346b815841f9bed6029ebcb06415caf640 upstream.
When filtering xattr list for reading, presence of trusted xattr
results in a security audit log. However, if there is other content
no errno will be set, and if there isn't, the errno will be -ENODATA
and not -EPERM as is usually associated with a lack of capability.
The check does not block the request to list the xattrs present.
Switch to ns_capable_noaudit to reflect a more appropriate check.

commit a016e2794fc3a245a91946038dd8f34d65e53cc3 upstream.
There may be situations when a server negotiates SMB 2.1
protocol version or higher but responds to a CREATE request
with an oplock rather than a lease.
Currently the client doesn't handle such a case correctly:
when another CREATE comes in the server sends an oplock
break to the initial CREATE and the client doesn't send
an ack back due to a wrong caching level being set (READ
instead of RWH). Missing an oplock break ack makes the
server wait until the break times out which dramatically
increases the latency of the second CREATE.
Fix this by properly detecting oplocks when using SMB 2.1
protocol version and higher.

commit c1e8220bd316d8ae8e524df39534b8a412a45d5e upstream.
If a program attempts to punch a hole on an inline data file, we need
to convert it to a normal file first.
This was detected using ext4/032 using the adv configuration. Simple
reproducer:
mke2fs -Fq -t ext4 -O inline_data /dev/vdc
mount /vdc
echo "" > /vdc/testfile
xfs_io -c 'truncate 33554432' /vdc/testfile
xfs_io -c 'fpunch 0 1048576' /vdc/testfile
umount /vdc

[BUG]
With fuzzed image and MIXED_GROUPS super flag, we can hit the following
BUG_ON():

[CAUSE]
This situation is caused by several factors:
- Fuzzed image
The extent tree of this fs missed one backref for extent tree root.
So we can allocated space from that slot.
- MIXED_BG feature
Super block has MIXED_BG flag.
- No mixed block groups exists
All block groups are just regular ones.
This makes data space_info->block_groups[] contains metadata block
groups. And when we reserve space for data, we can use space in
metadata block group.
Then we hit the following file operations:
- fallocate
We need to allocate data extents.
find_free_extent() choose to use the metadata block to allocate space
from, and choose the space of extent tree root, since its backref is
missing.
This generate one delayed ref head with is_data = 1.
- extent tree update
We need to update extent tree at run_delayed_ref time.
This generate one delayed ref head with is_data = 0, for the same
bytenr of old extent tree root.
Then we trigger the BUG_ON().
[FIX]
The quick fix here is to check block_group->flags before using it.
The problem can only happen for MIXED_GROUPS fs. Regular filesystems
won't have space_info with DATA|METADATA flag, and no way to hit the
bug.

The testcase fails because that, in fuzzed image, current segment was
allocated with LFS type, its .next_blkoff should point to an unused
block address, but actually, its bitmap shows it's not. So during
allocation, f2fs crash when setting bitmap.
Introducing sanity_check_curseg() to check such inconsistence of
current in-used segment.

[ Upstream commit a37d0862d17411edb67677a580a6f505ec2225f6 ]
As Pavel Machek reported:
"We normally use -EUCLEAN to signal filesystem corruption. Plus, it is
good idea to report it to the syslog and mark filesystem as "needing
fsck" if filesystem can do that."
Still we need improve the original patch with:
- use unlikely keyword
- add message print
- return EUCLEAN
However, after rethink this patch, I don't think we should add such
condition check here as below reasons:
- We have already checked the field in f2fs_sanity_check_ckpt(),
- If there is fs corrupt or security vulnerability, there is nothing
to guarantee the field is integrated after the check, unless we do
the check before each of its use, however no filesystem does that.
- We only have similar check for bitmap, which was added due to there
is bitmap corruption happened on f2fs' runtime in product.
- There are so many key fields in SB/CP/NAT did have such check
after f2fs_sanity_check_{sb,cp,..}.
So I propose to revert this unneeded check.
This reverts commit 56f3ce675103e3fb9e631cfb4131fc768bc23e9a.

As a part of the sanity checking while mounting, distinct segment number
assignment to data and node segments is verified. Fixing a small bug in
this verification between node and data segments. We need to check all
the data segments with all the node segments.

Fixes a regression introduced by the series of commits:
commit 272fcd1ca7ceb252b1c3a2961110c7c1722707cf
("ANDROID: overlayfs: override_creds=off option bypass creator_cred"),
commit aab9adb4b81bcce107dd1783f6ac41dc1abe9f15
("Merge 4.4.179 into android-4.4") that took in an incomplete,
backport of commit 54a07fff4b217607e862b2e1e3fcec32919ad583
("ovl: fix uid/gid when creating over whiteout") (or upstream
commit d0e13f5bbe4be7c8f27736fc40503dcec04b7de0
("ovl: fix uid/gid when creating over whiteout"))
where a crash is observed in ovl_create_or_link() when a
simple re-direction command in vendor directory.
/vendor/bin/<Any test> > /vendor/bin/test_log.txt 2>&1&
After further debugging we see that if the output is redirected to a
file which doesn’t exist we see this stack:
[ 377.382745] ovl_create_or_link+0xac/0x710
[ 377.382745] ovl_create_object+0xb8/0x110
[ 377.382745] ovl_create+0x34/0x40
[ 377.382745] path_openat+0xd44/0x15a8
[ 377.382745] do_filp_open+0x80/0x128
[ 377.382745] do_sys_open+0x140/0x250
[ 377.382745] __arm64_sys_openat+0x2c/0x38
ovl_override_creds returns NULL because the override_cred flag is set
to false. This causes ovl_revert_creds also to fail.
There is another call to check override_cred in override_cred call
which overrides the creds permanently as there no revert_creds
associated. So whenever next commit_cred is called we see the crash
as the credentials are permanently overridden.

This reverts commit 77bd558b2a02356a43b6e38de5168c6bb2afe9e8 which is
commit 56f3ce675103e3fb9e631cfb4131fc768bc23e9a upstream.
This is being done because segment.c is a bit "different" in this
branch, and we should keep the f2fs fixes away from here for now.
Otherwise the build breaks.
