[ Upstream commit 174d1232ebc84fcde8f5889d1171c9c7e74a10a7 ]
The chunk size of allocations in __gfs2_fallocate is calculated
incorrectly. The size can collapse, causing __gfs2_fallocate to
allocate one block at a time, which is very inefficient. This needs
fixing in two places:
In gfs2_quota_lock_check, always set ap->allowed to UINT_MAX to indicate
that there is no quota limit. This fixes callers that rely on
ap->allowed to be set even when quotas are off.
In __gfs2_fallocate, reset max_blks to UINT_MAX in each iteration of the
loop to make sure that allocation limits from one resource group won't
spill over into another resource group.

[ Upstream commit cc555b09d8c3817aeebda43a14ab67049a5653f7 ]
This patch fixes a deadlock caused when the jdata flag is set for
inodes that are already on the ordered write list. Since it is
on the ordered write list, log_flush calls gfs2_ordered_write which
calls filemap_fdatawrite. But since the inode had the jdata flag
set, that calls gfs2_jdata_writepages, which tries to start a new
transaction. A new transaction cannot be started because it tries
to acquire the log_flush rwsem which is already locked by the log
flush operation.
The bottom line is: We cannot switch an inode from ordered to jdata
until we eliminate any ordered data pages (via log flush) or any
log_flush operation afterward will create the circular dependency
above. So we need to flush the log before setting the diskflags to
switch the file mode, then we need to remove the inode from the
ordered writes list.
Before this patch, the log flush was done for jdata->ordered, but
that's wrong. If we're going from jdata to ordered, we don't need
to call gfs2_log_flush because the call to filemap_fdatawrite will
do it for us:
filemap_fdatawrite() -> __filemap_fdatawrite_range()
__filemap_fdatawrite_range() -> do_writepages()
do_writepages() -> gfs2_jdata_writepages()
gfs2_jdata_writepages() -> gfs2_log_flush()
This patch modifies function do_gfs2_set_flags so that if a file
has its jdata flag set, and it's already on the ordered write list,
the log will be flushed and it will be removed from the list
before setting the flag.

commit 10201655b085df8e000822e496e5d4016a167a36 upstream.
The switch to rhashtables (commit 88ffbf3e03) broke the debugfs glock
dump (/sys/kernel/debug/gfs2/<device>/glocks) for dumps bigger than a
single buffer: the right function for restarting an rhashtable iteration
from the beginning of the hash table is rhashtable_walk_enter;
rhashtable_walk_stop + rhashtable_walk_start will just resume from the
current position.
The upstream commit doesn't directly apply to 4.4.y because 4.4.y
doesn't have rhashtable_walk_enter and the following mainline commits:
92ecd73a887c4a2b94daf5fc35179d75d1c4ef95
gfs2: Deduplicate gfs2_{glocks,glstats}_open
cc37a62785a584f4875788689f3fd1fa6e4eb291
gfs2: Replace rhashtable_walk_init with rhashtable_walk_enter
Other than rhashtable_walk_enter, rhashtable_walk_init can fail. To
handle the failure case in gfs2_glock_seq_stop, we check if
rhashtable_walk_init has initialized iter->walker; if it has not, we
must not call rhashtable_walk_stop or rhashtable_walk_exit.

Before commit 88ffbf3e03 "GFS2: Use resizable hash table for glocks",
glocks were freed via call_rcu to allow reading the glock hashtable
locklessly using rcu. This was then changed to free glocks immediately,
which made reading the glock hashtable unsafe. Bring back the original
code for freeing glocks via call_rcu.

commit 67893f12e5374bbcaaffbc6e570acbc2714ea884 upstream.
We get a bogus warning about a potential uninitialized variable
use in gfs2, because the compiler does not figure out that we
never use the leaf number if get_leaf_nr() returns an error:
fs/gfs2/dir.c: In function 'get_first_leaf':
fs/gfs2/dir.c:802:9: warning: 'leaf_no' may be used uninitialized in this function [-Wmaybe-uninitialized]
fs/gfs2/dir.c: In function 'dir_split_leaf':
fs/gfs2/dir.c:1021:8: warning: 'leaf_no' may be used uninitialized in this function [-Wmaybe-uninitialized]
Changing the 'if (!error)' to 'if (!IS_ERR_VALUE(error))' is
sufficient to let gcc understand that this is exactly the same
condition as in IS_ERR() so it can optimize the code path enough
to understand it.

Commit 88ffbf3e03 switches to using rhashtables for glocks, hashing over
the entire struct lm_lockname instead of its individual fields. On some
architectures, struct lm_lockname contains a hole of uninitialized
memory due to alignment rules, which now leads to incorrect hash values.
Get rid of that hole.

commit 073931017b49d9458aa351605b43a7e34598caef upstream.
When file permissions are modified via chmod(2) and the user is not in
the owning group or capable of CAP_FSETID, the setgid bit is cleared in
inode_change_ok(). Setting a POSIX ACL via setxattr(2) sets the file
permissions as well as the new ACL, but doesn't clear the setgid bit in
a similar way; this allows to bypass the check in chmod(2). Fix that.

The xattr_handler operations are currently all passed a file system
specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example. In some oprations, it would be useful to also have
access to the handler prefix. To allow that, pass a pointer to the handler
to operations instead of the flags value alone.

Here is a list of patches we've accumulated for GFS2 for the current upstream
merge window. There are only six patches this time:
1. A cleanup patch from Andreas to remove the gl_spin #define in favor
of its value for the sake of clarity.
2. A fix from Andy Price to mark the inode dirty during fallocate.
3. A fix from Andy Price to set s_mode on mount failures to prevent
a stack trace.
4. A patch from me to prevent a kernel BUG() in trans_add_meta/trans_add_data
due to uninitialized storage.
5. A patch from me to protecting our freeing of the in-core directory
hash table to prevent double-free.
6. A fix for a page/block rounding problem that resulted in a metadata
coherency problem when the block size != page size.
I've got a lot more patches in various stages of review and testing,
but I'm afraid they'll have to wait until the next merge window. So
next time we're likely to have a lot more.

In the generic mount_bdev() function, deactivate_locked_super() is
called after the fill_super() call fails, at which point s_mode has been
set. kill_block_super() expects this and dumps a warning when
FMODE_EXCL is not set in s_mode.
In gfs2_mount() we call deactivate_locked_super() on failure of
gfs2_mount_args(), at which point s_mode has not yet been set. This
causes kill_block_super() to dump a stack trace when gfs2 fails to mount
with invalid options. Set s_mode earlier in gfs2_mount() to avoid that.

gfs2: A minor "sbstats" cleanup
gfs2: Fix a typo in a comment
gfs2: Make statistics unsigned, suitable for use with do_div()
GFS2: Use resizable hash table for glocks
GFS2: Move glock superblock pointer to field gl_name
gfs2: Simplify the seq file code for "sbstats"
Many file systems that implement the show_options hook fail to correctly
escape their output which could lead to unescaped characters (e.g. new
lines) leaking into /proc/mounts and /proc/[pid]/mountinfo files. This
could lead to confusion, spoofed entries (resulting in things like
systemd issuing false d-bus "mount" notifications), and who knows what
else. This looks like it would only be the root user stepping on
themselves, but it's possible weird things could happen in containers or
in other situations with delegated mount privileges.
Here's an example using overlay with setuid fusermount trusting the
contents of /proc/mounts (via the /etc/mtab symlink). Imagine the use
of "sudo" is something more sneaky:
$ BASE="ovl"
$ MNT="$BASE/mnt"
$ LOW="$BASE/lower"
$ UP="$BASE/upper"
$ WORK="$BASE/work/ 0 0
none /proc fuse.pwn user_id=1000"
$ mkdir -p "$LOW" "$UP" "$WORK"
$ sudo mount -t overlay -o "lowerdir=$LOW,upperdir=$UP,workdir=$WORK" none /mnt
$ cat /proc/mounts
none /root/ovl/mnt overlay rw,relatime,lowerdir=ovl/lower,upperdir=ovl/upper,workdir=ovl/work/ 0 0
none /proc fuse.pwn user_id=1000 0 0
$ fusermount -u /proc
$ cat /proc/mounts
cat: /proc/mounts: No such file or directory
This fixes the problem by adding new seq_show_option and
seq_show_option_n helpers, and updating the vulnerable show_option
handlers to use them as needed. Some, like SELinux, need to be open
coded due to unusual existing escape mechanisms.

Currently we have two different ways to signal an I/O error on a BIO:
(1) by clearing the BIO_UPTODATE flag
(2) by returning a Linux errno value to the bi_end_io callback
The first one has the drawback of only communicating a single possible
error (-EIO), and the second one has the drawback of not beeing persistent
when bios are queued up, and are not passed along from child to parent
bio in the ever more popular chaining scenario. Having both mechanisms
available has the additional drawback of utterly confusing driver authors
and introducing bugs where various I/O submitters only deal with one of
them, and the others have to add boilerplate code to deal with both kinds
of error returns.
So add a new bi_error field to store an errno value directly in struct
bio and remove the existing mechanisms to clean all this up.

This patch allows the block allocation code to retain the buffers
for the resource groups so they don't need to be re-read from buffer
cache with every request. This is a performance improvement that's
especially noticeable when resource groups are very large. For
example, with 2GB resource groups and 4K blocks, there can be 33
blocks for every resource group. This patch allows those 33 buffers
to be kept around and not read in and thrown away with every
operation. The buffers are released when the resource group is
either synced or invalidated.

The glocks used for resource groups often come and go hundreds of
thousands of times per second. Adding them to the lru list just
adds unnecessary contention for the lru_lock spin_lock, especially
considering we're almost certainly going to re-use the glock and
take it back off the lru microseconds later. We never want the
glock shrinker to cull them anyway. This patch adds a new bit in
the glops that determines which glock types get put onto the lru
list and which ones don't.
