commit a634644751c46238df58bbfe992e30c1668388db upstream.
Remove ocfs2_is_o2cb_active(). We have similar functions to identify
which cluster stack is being used via osb->osb_cluster_stack.
Secondly, the current implementation of ocfs2_is_o2cb_active() is not
totally safe. Based on the design of stackglue, we need to get
ocfs2_stack_lock before using ocfs2_stack related data structures, and
that active_stack pointer can be NULL in the case of mount failure.

[ Upstream commit 9de30f3f7f4d31037cfbb7c787e1089c1944b3a7 ]
In copy_result_to_user(), we first create a struct dlm_lock_result, which
contains a struct dlm_lksb, the last member of which is a pointer to the
lvb. Unfortunately, we copy the entire struct dlm_lksb to the result
struct, which is then copied to userspace at the end of the function,
leaking the contents of sb_lvbptr, which is a valid kernel pointer in some
cases (indeed, later in the same function the data it points to is copied
to userspace).
It is an error to leak kernel pointers to userspace, as it undermines KASLR
protections (see e.g. 65eea8edc31 ("floppy: Do not copy a kernel pointer to
user memory in FDGETPRM ioctl") for another example of this).

ocfs2_defrag_extent() might leak allocated clusters. When the file
system has insufficient space, the number of claimed clusters might be
less than the caller wants. If that happens, the original code might
directly commit the transaction without returning clusters.
This patch is based on code in ocfs2_add_clusters_in_btree().

[ Upstream commit cf76c78595ca87548ca5e45c862ac9e0949c4687 ]
ocfs2_read_blocks() and ocfs2_read_blocks_sync() are both used to read
several blocks from disk. Currently, the input argument *bhs* can be
NULL or NOT. It depends on the caller's behavior. If the function
fails in reading blocks from disk, the corresponding bh will be assigned
to NULL and put.
Obviously, above process for non-NULL input bh is not appropriate.
Because the caller doesn't even know its bhs are put and re-assigned.
If buffer head is managed by caller, ocfs2_read_blocks and
ocfs2_read_blocks_sync() should not evaluate it to NULL. It will cause
caller accessing illegal memory, thus crash.

Currently extent and index i are both being incremented causing an array
out of bounds read on extent[i]. Fix this by removing the extraneous
increment of extent.

Direct writes to empty inodes fail with EIO. The generic direct-io code
is in part to blame (a patch has been submitted as "direct-io: allow
direct writes to empty inodes"), but hfs is worse affected than the other
filesystems because the fallback to buffered I/O doesn't happen.
The problem is the return value of hfs_get_block() when called with
!create. Change it to be more consistent with the other modules.

The problem is the return value of hfsplus_get_block() when called with
!create. Change it to be more consistent with the other modules.

[ Upstream commit 54640c7502e5ed41fbf4eedd499e85f9acc9698f ]
Inserting a new record in a btree may require splitting several of its
nodes. If we hit ENOSPC halfway through, the new nodes will be left
orphaned and their records will be lost. This could mean lost inodes or
extents.
Henceforth, check the available disk space before making any changes.
This still leaves the potential problem of corruption on ENOMEM.
There is no need to reserve space before deleting a catalog record, as we
do for hfsplus. This difference is because hfs index nodes have fixed
length keys.

Inserting or deleting a record in a btree may require splitting several of
its nodes. If we hit ENOSPC halfway through, the new nodes will be left
orphaned and their records will be lost. This could mean lost inodes,
extents or xattrs.
Henceforth, check the available disk space before making any changes.
This still leaves the potential problem of corruption on ENOMEM.
The patch can be tested with xfstests generic/027.

[ Upstream commit ef75bcc5763d130451a99825f247d301088b790b ]
hfs_brec_update_parent() may hit BUG_ON() if the first record of both a
leaf node and its parent are changed, and if this forces the parent to
be split. It is not possible for this to happen on a valid hfs
filesystem because the index nodes have fixed length keys.
For reasons I ignore, the hfs module does have support for a number of
hfsplus features. A corrupt btree header may report variable length
keys and trigger this BUG, so it's better to fix it.

Creating, renaming or deleting a file may hit BUG_ON() if the first
record of both a leaf node and its parent are changed, and if this
forces the parent to be split. This bug is triggered by xfstests
generic/027, somewhat rarely; here is a more reliable reproducer:
truncate -s 50M fs.iso
mkfs.hfsplus fs.iso
mount fs.iso /mnt
i=1000
while [ $i -le 2400 ]; do
touch /mnt/$i &>/dev/null
((++i))
done
i=2400
while [ $i -ge 1000 ]; do
mv /mnt/$i /mnt/$(perl -e "print $i x61") &>/dev/null
((--i))
done
The issue is that a newly created bnode is being put twice. Reset
new_node to NULL in hfs_brec_update_parent() before reaching goto again.

The kernel module may sleep with holding a spinlock.

[FUNC] get_zeroed_page(GFP_NOFS)

fs/ocfs2/dlm/dlmmaster.c, 219: spin_lock in dlm_put_mle_inuse
To fix this bug, GFP_NOFS is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool DSAC.

In btrfs_search_old_slot get_old_root is always used with the assumption
it cannot fail. However, this is not true in rare circumstance it can
fail and return null. This will lead to null point dereference when the
header is read. Fix this by checking the return value and properly
handling NULL by setting ret to -EIO and returning gracefully.

Commit 56e94ea132bb ("fs: ocfs2: fix possible null-pointer dereferences
in ocfs2_xa_prepare_entry()") introduces a regression that fail to
create directory with mount option user_xattr and acl. Actually the
reported NULL pointer dereference case can be correctly handled by
loc->xl_ops->xlo_add_entry(), so revert it.

[ Upstream commit 1eb8d7387908022951792a46fa040ad3942b3b08 ]
Flushing the workqueue can cause operations to happen which might
call gfs2_log_reserve(), or get stuck waiting for locks taken by such
operations. gfs2_log_reserve() can io_schedule(). If this happens, it
will never wake because the only thing which can wake it is gfs2_logd()
which was already stopped.
This causes umount of a gfs2 filesystem to wedge permanently if, for
example, the umount immediately follows a large delete operation.
When this occured, the following stack trace was obtained from the
umount command

The terminating NUL byte is only there because the buffer is
allocated with kzalloc(PAGE_SIZE, GFP_KERNEL), but since the
range-check is off-by-one, and PAGE_SIZE==PATH_MAX, the
returned string may not be zero-terminated if it is exactly
PATH_MAX characters long. Furthermore also the initial loop
may theoretically exceed PATH_MAX and cause a fault.

[ Upstream commit 4f36cb36c9d14340bb200d2ad9117b03ce992cfe ]
The GFS2_RDF_UPTODATE flag in the rgrp is used to determine when
a rgrp buffer is valid. It's cleared when the glock is invalidated,
signifying that the buffer data is now invalid. But before this
patch, function update_rgrp_lvb was setting the flag when it
determined it had a valid lvb. But that's an invalid assumption:
just because you have a valid lvb doesn't mean you have valid
buffers. After all, another node may have made the lvb valid,
and this node just fetched it from the glock via dlm.
Consider this scenario:
1. The file system is mounted with RGRPLVB option.
2. In gfs2_inplace_reserve it locks the rgrp glock EX, but thanks
to GL_SKIP, it skips the gfs2_rgrp_bh_get.
3. Since loops == 0 and the allocation target (ap->target) is
bigger than the largest known chunk of blocks in the rgrp
(rs->rs_rbm.rgd->rd_extfail_pt) it skips that rgrp and bypasses
the call to gfs2_rgrp_bh_get there as well.
4. update_rgrp_lvb sees the lvb MAGIC number is valid, so bypasses
gfs2_rgrp_bh_get, but it still sets sets GFS2_RDF_UPTODATE due
to this invalid assumption.
5. The next time update_rgrp_lvb is called, it sees the bit is set
and just returns 0, assuming both the lvb and rgrp are both
uptodate. But since this is a smaller allocation, or space has
been freed by another node, thus adjusting the lvb values,
it decides to use the rgrp for allocations, with invalid rd_free
due to the fact it was never updated.
This patch changes update_rgrp_lvb so it doesn't set the UPTODATE
flag anymore. That way, it has no choice but to fetch the latest
values.

commit 762c69685ff7ad5ad7fee0656671e20a0c9c864d upstream.
We need to get the underlying dentry of parent; sure, absent the races
it is the parent of underlying dentry, but there's nothing to prevent
losing a timeslice to preemtion in the middle of evaluation of
lower_dentry->d_parent->d_inode, having another process move lower_dentry
around and have its (ex)parent not pinned anymore and freed on memory
pressure. Then we regain CPU and try to fetch ->d_inode from memory
that is freed by that point.
dentry->d_parent *is* stable here - it's an argument of ->lookup() and
we are guaranteed that it won't be moved anywhere until we feed it
to d_add/d_splice_alias. So we safely go that way to get to its
underlying dentry.

commit e72b9dd6a5f17d0fb51f16f8685f3004361e83d0 upstream.
lower_dentry can't go from positive to negative (we have it pinned),
but it *can* go from negative to positive. So fetching ->d_inode
into a local variable, doing a blocking allocation, checking that
now ->d_inode is non-NULL and feeding the value we'd fetched
earlier to a function that won't accept NULL is not a good idea.

commit 65de03e251382306a4575b1779c57c87889eee49 upstream.
cgroup writeback tries to refresh the associated wb immediately if the
current wb is dead. This is to avoid keeping issuing IOs on the stale
wb after memcg - blkcg association has changed (ie. when blkcg got
disabled / enabled higher up in the hierarchy).
Unfortunately, the logic gets triggered spuriously on inodes which are
associated with dead cgroups. When the logic is triggered on dead
cgroups, the attempt fails only after doing quite a bit of work
allocating and initializing a new wb.
While c3aab9a0bd91 ("mm/filemap.c: don't initiate writeback if mapping
has no dirty pages") alleviated the issue significantly as it now only
triggers when the inode has dirty pages. However, the condition can
still be triggered before the inode is switched to a different cgroup
and the logic simply doesn't make sense.
Skip the immediate switching if the associated memcg is dying.
This is a simplified version of the following two patches:

commit 351e5d869e5ac10cb40c78b5f2d7dfc816ad4587 upstream.
Configfs abuses symlink(2). Unlike the normal filesystems, it
wants the target resolved at symlink(2) time, like link(2) would've
done. The problem is that ->symlink() is called with the parent
directory locked exclusive, so resolving the target inside the
->symlink() is easily deadlocked.
Short of really ugly games in sys_symlink() itself, all we can
do is to unlock the parent before resolving the target and
relock it after. However, that invalidates the checks done
by the caller of ->symlink(), so we have to
* check that dentry is still where it used to be
(it couldn't have been moved, but it could've been unhashed)
* recheck that it's still negative (somebody else
might've successfully created a symlink with the same name
while we were looking the target up)
* recheck the permissions on the parent directory.

commit ea60ed6fcf29eebc78f2ce91491e6309ee005a01 upstream.

[ 293.903417] entry_SYSCALL_64_after_hwframe+0x44/0xa9
This happens because __ceph_remove_cap() may queue a cap release
(__ceph_queue_cap_release) which can be scheduled before that cap is
removed from the inode list with
rb_erase(&cap->ci_node, &ci->i_caps);
And, when this finally happens, the use-after-free will occur.
This can be fixed by removing the cap from the inode list before being
removed from the session list, and thus eliminating the risk of an UAF.

During backport 1e2e547a93a "do d_instantiate/unlock_new_inode
combinations safely", there was a error instantiating sequence of
attaching dentry to inode and calling security_d_instantiate().
Before commit ce23e640133 "->getxattr(): pass dentry and inode as
separate arguments" and b96809173e9 "security_d_instantiate(): move to
the point prior to attaching dentry to inode", security_d_instantiate()
should be called beind __d_instantiate(), otherwise it will trigger
below problem when CONFIG_SECURITY_SMACK on ext4 was enabled because
d_inode(dentry) used by ->getxattr() is NULL before __d_instantiate()
instantiate inode.

[ Upstream commit d46b0da7a33dd8c99d969834f682267a45444ab3 ]
There's a deadlock that is possible and can easily be seen with
a test where multiple readers open/read/close of the same file
and a disruption occurs causing reconnect. The deadlock is due
a reader thread inside cifs_strict_readv calling down_read and
obtaining lock_sem, and then after reconnect inside
cifs_reopen_file calling down_read a second time. If in
between the two down_read calls, a down_write comes from
another process, deadlock occurs.
CPU0 CPU1
---- ----
cifs_strict_readv()
down_read(&cifsi->lock_sem);
_cifsFileInfo_put
OR
cifs_new_fileinfo
down_write(&cifsi->lock_sem);
cifs_reopen_file()
down_read(&cifsi->lock_sem);
Fix the above by changing all down_write(lock_sem) calls to
down_write_trylock(lock_sem)/msleep() loop, which in turn
makes the second down_read call benign since it will never
block behind the writer while holding lock_sem.

commit 19957a181608d25c8f4136652d0ea00b3738972d upstream.
Due to an inverted logic mistake in xfs_buftarg_isolate()
the xfs_buffers with zero b_lru_ref will take another trip
around LRU, while isolating buffers with non-zero b_lru_ref.
Additionally those isolated buffers end up right back on the LRU
once they are released, because b_lru_ref remains elevated.
Fix that circuitous route by leaving them on the LRU
as originally intended.

commit b24e7598db62386a95a3c8b9c75630c5d56fe077 upstream.
If writeback cache is enabled, then writes might get reordered with
chmod/chown/utimes. The problem with this is that performing the write in
the fuse daemon might itself change some of these attributes. In such case
the following sequence of operations will result in file ending up with the
wrong mode, for example:
int fd = open ("suid", O_WRONLY|O_CREAT|O_EXCL);
write (fd, "1", 1);
fchown (fd, 0, 0);
fchmod (fd, 04755);
close (fd);
This patch fixes this by flushing pending writes before performing
chown/chmod/utimes.

[ Upstream commit 2abb7d3b12d007c30193f48bebed781009bebdd2 ]
In ocfs2_info_scan_inode_alloc(), there is an if statement on line 283
to check whether inode_alloc is NULL:
if (inode_alloc)
When inode_alloc is NULL, it is used on line 287:
ocfs2_inode_lock(inode_alloc, &bh, 0);
ocfs2_inode_lock_full_nested(inode, ...)
struct ocfs2_super *osb = OCFS2_SB(inode->i_sb);
Thus, a possible null-pointer dereference may occur.
To fix this bug, inode_alloc is checked on line 286.
This bug is found by a static analysis tool STCheck written by us.
