Under heavy I/O load, writing the disk heartbeat can be forced to wait for
minutes, and this causes the node to be fenced.
This patch tries to use WRITE_SYNC in submitting the heartbeat bio, so
that writing the heartbeat will have a priority over other requests.

Inlined xattr shared free space of inode block with inlined data or data
extent record, so the size of the later two should be adjusted when
inlined xattr is enabled. See ocfs2_xattr_ibody_init(). But this isn't
done well when reflink. For inode with inlined data, its max inlined
data size is adjusted in ocfs2_duplicate_inline_data(), no problem. But
for inode with data extent record, its record count isn't adjusted. Fix
it, or data extent record and inlined xattr may overwrite each other,
then cause data corruption or xattr failure.
One panic caused by this bug in our test environment is the following:

While deleting a file with ocfs2_unlink(), there is a bug in this
function. This bug will result in filesystem read-only.
After calling ocfs2_orphan_add(), the file which will be deleted is
added into orphan dir. If ocfs2_delete_entry() fails, the file still
exists in the parent dir. And this scenario introduces a conflict of
metadata.
If a file is added into orphan dir, when we put inode of the file with
iput(), the inode i_flags is setted (~OCFS2_VALID_FL) in
ocfs2_remove_inode(), and then write back to disk.
But as previously mentioned, the file still exists in the parent dir.
On other nodes, the file can be still accessed. When first read the
file with ocfs2_read_blocks() from disk, It will check and avalidate
inode using ocfs2_validate_inode_block(). So File system will be
readonly because the inode is invalid. In other words, the inode
i_flags has been set (~OCFS2_VALID_FL).

In ocfs2_relink_block_group(), we roll back all those changes if notify
intent to modify buffers for metadata update failed even if the relevant
buffer has not yet been modified/got dirty at that point, that are not
quite right because of:
- None buffer has been modified/dirty if failed to call
ocfs2_journal_access_gd() against the previous block group buffer
- Only the previous block group buffer has got dirty if failed to call
ocfs2_journal_access_gd() against the block group buffer
- There is no need to roll back the change for file entry buffer at all
Those problems will not cause anything wrong but unnecessary. This
patch fix them and kill the useless bg_ptr variable as well.

While adding a file into orphan dir in ocfs2_orphan_add(), it calls
__ocfs2_add_entry() before ocfs2_journal_access_di(). If
ocfs2_journal_access_di() failed, the file is added into orphan dir, and
orphan dir dinode updated, but file dinode has not been updated.
Accordingly, the data is not consistent between file dinode and orphan
dir.
So, need to call ocfs2_journal_access_di() before __ocfs2_add_entry(),
and if ocfs2_journal_access_di() failed, orphan_fe and
orphan_dir_inode->i_nlink need rollback.
This bug was added by 3939fda4 ("Ocfs2: Journaling i_flags and
i_orphaned_slot when adding inode to orphan dir.").

blocked list
dlmlock_master() returns DLM_RECOVERING/DLM_MIGRATING/ DLM_FORWAR after
adding lock to blocked list if lockres has the state
DLM_LOCK_RES_RECOVERING/DLM_LOCK_RES_MIGRATING/ DLM_LOCK_RES_IN_PROGRESS.
so it will retry in dlmlock(). And this may cause dlm_thread fall into an
infinite loop
Thread1 dlm_thread
calls dlm_lock->dlmlock_master,
if lockresA is in state
DLM_LOCK_RES_RECOVERING, calls
__dlm_wait_on_lockres() and waits
until others threads clear this
state;
If cannot grant this lock,
adding lock to blocked list,
and return DLM_RECOVERING;
Grant this lock and move it to
grant list;
After a while, retry and
calls list_add_tail(), adding lock
to blocked list again.
Granted and blocked list of this lockres will become the following
conditions:
lock_res->granted.next = dlm_lock->list_head;
lock_res->blocked.next = dlm_lock->list_head;
dlm_lock->list_head.next = dlm_lock_resource->blocked;
When dlm_thread traverses the granted list, it will fall into an endless
loop, checking dlm_lock.list_head, dlm_lock->list_head.next
(i.e.lock_res->blocked), lock_res->blocked.next(i.e.dlm_lock.list_head
again) .....

We can't use !req->r_sent to check if OSD request is sent for the
first time, this is because __cancel_request() zeros req->r_sent
when OSD map changes. Rather than adding a new variable to struct
ceph_osd_request to indicate if it's sent for the first time, We
can call the unsafe callback only when unsafe OSD reply is received.
If OSD's first reply is safe, just skip calling the unsafe callback.
The purpose of unsafe callback is adding unsafe request to a list,
so that fsync(2) can wait for the safe reply. fsync(2) doesn't need
to wait for a write(2) that hasn't returned yet. So it's OK to add
request to the unsafe list when the first OSD reply is received.
(ceph_sync_write() returns after receiving the first OSD reply)

If caps are been revoking by the auth MDS, don't consider them as
issued even they are still issued by non-auth MDS. The non-auth
MDS should also be revoking/exporting these caps, the client just
hasn't received the cap revoke/export message.
The race I encountered is: When caps are exporting to new MDS, the
client receives cap import message and cap revoke message from the
new MDS, then receives cap export message from the old MDS. When
the client receives cap revoke message from the new MDS, the revoking
caps are still issued by the old MDS, so the client does nothing.
Later when the cap export message is received, the client removes
the caps issued by the old MDS. (Another way to fix the race is
calling ceph_check_caps() in handle_cap_export())

A malicious monitor can craft an auth reply message that could cause a
NULL function pointer dereference in the client's kernel.
To prevent this, the auth_none protocol handler needs an empty
ceph_auth_client_ops->build_request() function.

The different between file_start/end_write and sb_start/end_write is
file_ only handle regular file.But i think in ceph_aio_write,it only

Updating an image header needs to be protected to ensure it's
done consistently. However distinct headers can be updated
concurrently without a problem. Instead of using the global
control lock to serialize headder updates, just rely on the header
semaphore. (It's already used, this just moves it out to cover
a broader section of the code.)
That leaves the control mutex protecting only the creation of rbd
clients, so rename it.
This resolves:

When an rbd device is first getting mapped, its device registration
is protected the control mutex. There is no need to do that though,
because the device has already been assigned an id that's guaranteed
to be unique.
An unmap of an rbd device won't proceed if the device has a non-zero
open count or is already being unmapped. So there's no need to hold
the control mutex in that case either.
Finally, an rbd device can't be opened if it is being removed, and
it won't go away if there is a non-zero open count. So here too
there's no need to hold the control mutex while getting or putting a
reference to an rbd device's Linux device structure.
Drop the mutex calls in these cases.

When unmapping a device, its id is supplied, and that is used to
look up which rbd device should be unmapped. Looking up the
device involves searching the rbd device list while holding
a spinlock that protects access to that list.
Currently all of this is done under protection of the control lock,
but that protection is going away soon. To ensure the rbd_dev is
still valid (still on the list) while setting its REMOVING flag, do
so while still holding the list lock. To do so, get rid of
__rbd_get_dev(), and open code what it did in the one place it
was used.

If an osd client response message arrives that has a front section
that's too big for the buffer set aside to receive it, a warning
gets reported and a new buffer is allocated.
The warning says nothing about which connection had the problem.

informative.

If more than one rbd image has the same ceph cluster configuration
(same options, same set of monitors, same keys) they normally share
a single rbd client.
When an image is getting mapped, rbd looks to see if an existing
client can be used, and creates a new one if not.
The lookup and creation are not done under a common lock though, so
mapping two images concurrently could lead to duplicate clients
getting set up needlessly. This isn't a major problem, but it's
wasteful and different from what's intended.
This patch fixes that by using the control mutex to protect
both the lookup and (if needed) creation of the client. It
was previously used just when creating.
