commit 6d6d282932d1a609e60dc4467677e0e863682f57 upstream.
`btrfs sub set-default` succeeds to set an ID which isn't corresponding to any
fs/file tree. If such the bad ID is set to a filesystem, we can't mount this
filesystem without specifying `subvol` or `subvolid` mount options.
Fixes: 6ef5ed0d386b ("Btrfs: add ioctl and incompat flag to set the default mount subvol")

commit 78ad4ce014d025f41b8dde3a81876832ead643cf upstream.
btrfs_cmp_data_prepare() (almost) always returns 0 i.e. ignoring errors
from gather_extent_pages(). While the pages are freed by
btrfs_cmp_data_free(), cmp->num_pages still has > 0. Then,
btrfs_extent_same() try to access the already freed pages causing faults
(or violates PageLocked assertion).
This patch just return the error as is so that the caller stop the process.

commit fc46820b27a2d9a46f7e90c9ceb4a64a1bc5fab8 upstream.
In generic_file_llseek_size, return -ENXIO for negative offsets as well
as offsets beyond EOF. This affects filesystems which don't implement
SEEK_HOLE / SEEK_DATA internally, possibly because they don't support
holes.
Fixes xfstest generic/448.

commit 0603c96f3af50e2f9299fa410c224ab1d465e0f9 upstream.
As long as signing is supported (ie not a guest user connection) and
connection is SMB3 or SMB3.02, then validate negotiate (protect
against man in the middle downgrade attacks). We had been doing this
only when signing was required, not when signing was just enabled,
but this more closely matches recommended SMB3 behavior and is
better security. Suggested by Metze.

commit f5c4ba816315d3b813af16f5571f86c8d4e897bd upstream.
There is a race that cause cifs reconnect in cifs_mount,
- cifs_mount
- cifs_get_tcp_session
- [ start thread cifs_demultiplex_thread
- cifs_read_from_socket: -ECONNABORTED
- DELAY_WORK smb2_reconnect_server ]
- cifs_setup_session
- [ smb2_reconnect_server ]
auth_key.response was allocated in cifs_setup_session, and
will release when the session destoried. So when session re-
connect, auth_key.response should be check and released.
Tested with my system:
CIFS VFS: Free previous auth_key.response = ffff8800320bbf80
A simple auth_key.response allocation call trace:
- cifs_setup_session
- SMB2_sess_setup
- SMB2_sess_auth_rawntlmssp_authenticate
- build_ntlmssp_auth_blob
- setup_ntlmv2_rsp

commit 5fe457430e554a2f5188f13c1a2e36ad845640c5 upstream.
This patch introduces a new flag to indicate inode status of doing atomic
write committing, so that, we can keep atomic write status for inode
during atomic committing, then we can skip GCing pages of atomic write inode,
that avoids random GCed datas being mixed with current transaction, so
isolation of transaction can be kept.

commit 0a595ebaaa6b53a2226d3fee2a2fd616ea5ba378 upstream.
This patch implements IO alignment by filling dummy blocks in DATA and NODE
write bios. If we can guarantee, for example, 32KB or 64KB for such the IOs,
we can eliminate underlying dummy page problem which FTL conducts in order to
close MLC or TLC partial written pages.
Note that,
- it requires "-o mode=lfs".
- IO size should be power of 2, not exceed BIO_MAX_PAGES, 256.
- read IO is still 4KB.
- do checkpoint at fsync, if dummy NODE page was written.

commit 07fe8d44409f88be8f4a4e8f22b47ee709a22657 upstream.
We checked that "inode" is not an error pointer earlier so there is
no need to check again here.

commit 5c9e418436f3445d7cc4f3ba2964f231a4b33f17 upstream.
If we run out of memory, in cache_nat_entry, it's better to avoid loop
for allocating memory to cache nat entry, so in low memory scenario, for
read path of node block, I expect this can avoid unneeded latency.

Remove declaration of function max_file_size(). It was added
with:
63ba8a3 BACKPORT: f2fs: add a max block check for get_data_block_bmap
On merging of android-4.4@d68ba9f (4.4.89) functional part of
the above change was replaced with the upstream's one, which do
not use max_file_size() and also this function was renamed to
max_file_blocks() in its definition with change c1286ff. In
android-4.4 this func was static, hence no declaration line in
f2fs.h and this is why it was left alone in msm-4.4 without to
be noticed.

of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs)

So far we initialized bd_bdi only in bdget(). That is fine for normal
bdev inodes however for the special case of the root inode of
blockdev_superblock that function is never called and thus bd_bdi is
left uninitialized. As a result bdev_evict_inode() may oops doing
bdi_put(root->bd_bdi) on that inode as can be seen when doing:
mount -t bdev none /mnt
Fix the problem by initializing bd_bdi when first allocating the inode
and then reinitializing bd_bdi in bdev_evict_inode().
Thanks to syzkaller team for finding the problem.

Currenly blk_get_backing_dev_info() is not safe to be called when the
block device is not open as bdev->bd_disk is NULL in that case. However
inode_to_bdi() uses this function and may be call called from flusher
worker or other writeback related functions without bdev being open
which leads to crashes such as:

Currently, block device inodes stay around after corresponding gendisk
hash died until memory reclaim finds them and frees them. Since we will
make block device inode pin the bdi, we want to free the block device
inode as soon as the device goes away so that bdi does not stay around
unnecessarily. Furthermore we need to avoid issues when new device with
the same major,minor pair gets created since reusing the bdi structure
would be rather difficult in this case.
Unhashing block device inode on gendisk destruction nicely deals with
these problems. Once last block device inode reference is dropped (which
may be directly in del_gendisk()), the inode gets evicted. Furthermore if
the major,minor pair gets reallocated, we are guaranteed to get new
block device inode even if old block device inode is not yet evicted and
thus we avoid issues with possible reuse of bdi.

commit 95f1fda47c9d8738f858c3861add7bf0a36a7c0b upstream.
Quota does not get enabled for read-only mounts if filesystem
has quota feature, so that quotas cannot updated during orphan
cleanup, which will lead to quota inconsistency.
This patch turn on quotas during orphan cleanup for this case,
make sure quotas can be updated correctly.

commit b0a5a9589decd07db755d6a8d9c0910d96ff7992 upstream.
Current ext4 quota should always "usage enabled" if the
quota feautre is enabled. But in ext4_orphan_cleanup(), it
turn quotas off directly (used for the older journaled
quota), so we cannot turn it on again via "quotaon" unless
umount and remount ext4.
Simple reproduce:
mkfs.ext4 -O project,quota /dev/vdb1
mount -o prjquota /dev/vdb1 /mnt
chattr -p 123 /mnt
chattr +P /mnt
touch /mnt/aa /mnt/bb
exec 100<>/mnt/aa
rm -f /mnt/aa
sync
echo c > /proc/sysrq-trigger
#reboot and mount
mount -o prjquota /dev/vdb1 /mnt
#query status
quotaon -Ppv /dev/vdb1
#output
quotaon: Cannot find mountpoint for device /dev/vdb1
quotaon: No correct mountpoint specified.
This patch add check for journaled quotas to avoid incorrect
quotaoff when ext4 has quota feautre.

With the suggested change, I am no longer able to reproduce the above oops.
