There are flags to enable two specialized features in the dlm:
1. CONVDEADLK causes the dlm to resolve conversion deadlocks internally by
changing the granted mode of locks to NL.
2. ALTPR/ALTCW cause the dlm to change the requested mode of locks to PR
or CW to grant them if the normal requested mode can't be granted.
GFS direct i/o exercises both of these features, especially when mixed
with buffered i/o. The dlm has problems with them.
The first problem is on the master node. If it demotes a lock as a part of
converting it, the actual step of converting the lock isn't being done
after the demotion, the lock is just left sitting on the granted queue
with a granted mode of NL. I think the mistaken assumption was that the
call to grant_pending_locks() would grant it, but that function naturally
doesn't look at locks on the granted queue.
The second problem is on the process node. If the master either demotes
or gives an altmode, the munging of the gr/rq modes is never done in the
process copy of the lock, leaving the master/process copies out of sync.

This patch consolidates the TCP & SCTP protocols for the DLM into a single file
and makes it switchable at run-time (well, at least before the DLM actually
starts up!)
For RHEL5 this patch requires Neil Horman's patch that expands the in-kernel
socket API but that has already been twice ACKed so it should be OK.
The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c
& lowcomms-tcp.c files.

A lock id is a uint32 and is used as an opaque reference to the lock. For
userland apps, the lkid is passed up, through libdlm, as the return value
from a write() on the dlm device. This created a problem when the high
bit was 1, making the lkid look like an error. This is fixed by changing
how the lkid is composed. The low 16 bits identified the hash bucket for
the lock and the high 16 bits were a per-bucket counter (which eventually
hit 0x8000 causing the problem). These are simply swapped around; the
number of hash table buckets is far below 0x8000, making all lkid's
positive when viewed as signed.

Add code for purging orphan locks. A process can also purge all of its
own non-orphan locks by passing a pid of zero. Code already exists for
processes to create persistent locks that become orphans when the process
exits, but the complimentary capability for another process to then purge
these orphans has been missing.

Full cancel and force-unlock support. In the past, cancel and force-unlock
wouldn't work if there was another operation in progress on the lock. Now,
both cancel and unlock-force can overlap an operation on a lock, meaning there
may be 2 or 3 operations in progress on a lock in parallel. This support is
important not only because cancel and force-unlock are explicit operations
that an app can use, but both are used implicitly when a process exits while
holding locks.
Summary of changes:
- add-to and remove-from waiters functions were rewritten to handle situations
with more than one remote operation outstanding on a lock
- validate_unlock_args detects when an overlapping cancel/unlock-force
can be sent and when it needs to be delayed until a request/lookup
reply is received
- processing request/lookup replies detects when cancel/unlock-force
occured during the op, and carries out the delayed cancel/unlock-force
- manipulation of the "waiters" (remote operation) state of a lock moved under
the standard rsb mutex that protects all the other lock state
- the two recovery routines related to locks on the waiters list changed
according to the way lkb's are now locked before accessing waiters state
- waiters recovery detects when lkb's being recovered have overlapping
cancel/unlock-force, and may not recover such locks
- revert_lock (cancel) returns a value to distinguish cases where it did
nothing vs cases where it actually did a cancel; the cancel completion ast
should only be done when cancel did something
- orphaned locks put on new list so they can be found later for purging
- cancel must be called on a lock when making it an orphan
- flag user locks (ENDOFLIFE) at the end of their useful life (to the
application) so we can return an error for any further cancel/unlock-force
- we weren't setting COMP/BAST ast flags if one was already set, so we'd lose
either a completion or blocking ast
- clear an unread bast on a lock that's become unlocked

Currently if the lockspace removal fails the misc device associated with a
lockspace is left deleted. After that there is no way to access the orphaned
lockspace from userland.
This patch recreates the misc device if th dlm_release_lockspace fails. I
believe this is better than attempting to remove the lockspace first because
that leaves an unattached device lying around. The potential gap in which there
is no access to the lockspace between removing the misc device and recreating it
is acceptable ... after all the application is trying to remove it, and only new
users of the lockspace will be affected.

A long, complicated sequence of events, beginning with the RESEND flag not
being cleared on an lkb, can result in an unlock never completing.
- lkb on waiters list for remote lookup
- the remote node is both the dir node and the master node, so
it optimizes the lookup into a request and sends a request
reply back
- the request reply is saved on the requestqueue to be processed
after recovery
- recovery runs dlm_recover_waiters_pre() which sets RESEND flag
so the lookup will be resent after recovery
- end of recovery: process_requestqueue takes saved request reply
which removes the lkb off the waitesr list, _without_ clearing
the RESEND flag
- end of recovery: dlm_recover_waiters_post() doesn't do anything
with the now completed lookup lkb (would usually clear RESEND)
- later, the node unmounts, unlocks this lkb that still has RESEND
flag set
- the lkb is on the waiters list again, now for unlock, when recovery
occurs, dlm_recover_waiters_pre() shows the lkb for unlock with RESEND
set, doesn't do anything since the master still exists
- end of recovery: dlm_recover_waiters_post() takes this lkb off
the waiters list because it has the RESEND flag set, then reports
an error because unlocks are never supposed to be handled in
recover_waiters_post().
- later, the unlock reply is received, doesn't find the lkb on
the waiters list because recover_waiters_post() has wrongly
removed it.
- the unlock operation has been lost, and we're left with a
stray granted lock
- unmount spins waiting for the unlock to complete
The visible evidence of this problem will be a node where gfs umount is
spinning, the dlm waiters list will be empty, and the dlm locks list will
show a granted lock.
The fix is simply to clear the RESEND flag when taking an lkb off the
waiters list.

dlm_receive_message() returns 0 instead of returning 'error'. What would
happen is that process_requestqueue would take a saved message off the
requestqueue and call receive_message on it. receive_message would then
see that recovery had been aborted, set error to EINTR, and 'goto out',
expecting that the error would be returned. Instead, 0 was always
returned, so process_requestqueue would think that the message had been
processed and delete it instead of saving it to process next time. This
means the message (usually an unlock in my tests) would be lost.

If master recovery happens on an rsb in one recovery sequence, then that
sequence is aborted before lock recovery happens, then in the next
sequence, we rely on the previous master recovery (which may now be
invalid due to another node ignoring a lookup result) and go on do to the
lock recovery where we get stuck due to an invalid master value.
recovery cycle begins: master of rsb X has left
nodes A and B send node C an rcom lookup for X to find the new master
C gets lookup from B first, sets B as new master, and sends reply back to B
C gets lookup from A next, and sends reply back to A saying B is master
A gets lookup reply from C and sets B as the new master in the rsb
recovery cycle on A, B and C is aborted to start a new recovery
B gets lookup reply from C and ignores it since there's a new recovery
recovery cycle begins: some other node has joined
B doesn't think it's the master of X so it doesn't rebuild it in the directory
C looks up the master of X, no one is master, so it becomes new master
B looks up the master of X, finds it's C
A believes that B is the master of X, so it sends its lock to B
B sends an error back to A
A resends
this repeats forever, the incorrect master value on A is never corrected
The fix is to do master recovery on an rsb that still has the NEW_MASTER
flag set from an earlier recovery sequence, and therefore didn't complete
lock recovery.

When a user process exits, we clear all the locks it holds. There is a
problem, though, with locks that the process had begun unlocking before it
exited. We couldn't find the lkb's that were in the process of being
unlocked remotely, to flag that they are DEAD. To solve this, we move
lkb's being unlocked onto a new list in the per-process structure that
tracks what locks the process is holding. We can then go through this
list to flag the necessary lkb's when clearing locks for a process when it
exits.

When the dlm fakes an unlock/cancel reply from a failed node using a stub
message struct, it wasn't setting the flags in the stub message. So, in
the process of receiving the fake message the lkb flags would be updated
and cleared from the zero flags in the message. The problem observed in
tests was the loss of the USER flag which caused the dlm to think a user
lock was a kernel lock and subsequently fail an assertion checking the
validity of the ast/callback field.

The send_args() function is used to copy parameters into a message for a

send_args was wrongly copying the lvb for all message types as long as the
lock had an lvb. This means that the lvb data was being written past the

A reply to a recovery message will often be received after the relevant
recovery sequence has aborted and the next recovery sequence has begun.
We need to ignore replies to these old messages from the previous
recovery. There's already a way to do this for synchronous recovery
requests using the rc_id number, but not for async.
Each recovery sequence already has a locally unique sequence number
associated with it. This patch adds a field to the rcom (recovery
message) structure where this recovery sequence number can be placed,
rc_seq. When a node sends a reply to a recovery request, it copies the
rc_seq number it received into rc_seq_reply. When the first node receives
the reply to its recovery message, it will check whether rc_seq_reply
matches the current recovery sequence number, ls_recover_seq, and if not
then it ignores the old reply.
An old, inadequate approach to filtering out old replies (checking if the
current stage of recovery has moved back to the start) has been removed
from two spots.
The protocol version number is changed to reflect the different rcom
structures.

There's a chance the new master of resource hasn't learned it's the new
master before another node sends it a lock during recovery. The node
sending the lock needs to resend if this happens.
- A sends a master lookup for resource R to C
- B sends a master lookup for resource R to C
- C receives A's lookup, assigns A to be master of R and
sends a reply back to A
- C receives B's lookup and sends a reply back to B saying
that A is the master
- B receives lookup reply from C and sends its lock for R to A
- A receives lock from B, doesn't think it's the master of R
and sends an error back to B
- A receives lookup reply from C and becomes master of R
- B gets error back from A and resends its lock back to A
(this resending is what this patch does)
- A receives lock from B, it now sees it's the master of R
and takes the lock
