2008-01-30dlm: limit dir lookup loopDavid Teigland1-2/+4
In a rare case we may need to repeat a local resource directory lookup due to a race with removing the rsb and removing the resdir record. We'll never need to do more than a single additional lookup, though, so the infinite loop around the lookup can be removed. In addition to being unnecessary, the infinite loop is dangerous since some other unknown condition may appear causing the loop to never break. Signed-off-by: David Teigland <teigland@redhat.com>
2008-01-30dlm: reject normal unlock when lock is waiting for lookupDavid Teigland1-4/+5
Non-forced unlocks should be rejected if the lock is waiting on the rsb_lookup list for another lock to establish the master node. Signed-off-by: David Teigland <teigland@redhat.com>
2008-01-30dlm: validate messages before processingDavid Teigland1-35/+104
There was some hit and miss validation of messages that has now been cleaned up and unified. Before processing a message, the new validate_message() function checks that the lkb is the appropriate type, process-copy or master-copy, and that the message is from the correct nodeid for the the given lkb. Other checks and assertions on the lkb type and nodeid have been removed. The assertions were particularly bad since they would panic the machine instead of just ignoring the bad message. Although other recent patches have made processing old message unlikely, it still may be possible for an old message to be processed and caught by these checks.

2008-01-30dlm: reject messages from non-membersDavid Teigland3-4/+12
Messages from nodes that are no longer members of the lockspace should be ignored. When nodes are removed from the lockspace, recovery can sometimes complete quickly enough that messages arrive from a removed node after recovery has completed. When processed, these messages would often cause an error message, and could in some cases change some state, causing problems. Signed-off-by: David Teigland <teigland@redhat.com>
2008-01-30dlm: another call to confirm_master in receive_request_replyDavid Teigland1-2/+6
When a failed request (EBADR or ENOTBLK) is unlocked/canceled instead of retried, there may be other lkb's waiting on the rsb_lookup list for it to complete. A call to confirm_master() is needed to move on to the next waiting lkb since the current one won't be retried. Signed-off-by: David Teigland <teigland@redhat.com>
2008-01-30dlm: recover locks waiting for overlap repliesDavid Teigland1-5/+32
When recovery looks at locks waiting for replies, it fails to consider locks that have already received a reply for their first remote operation, but not received a reply for secondary, overlapping unlock/cancel. The appropriate stub reply needs to be called for these waiters. Appears when we start doing recovery in the presence of a many overlapping unlock/cancel ops. Signed-off-by: David Teigland <teigland@redhat.com>
2008-01-30dlm: clear ast_type when removing from astqueueDavid Teigland1-0/+1
The lkb_ast_type field indicates whether the lkb is on the astqueue list. When clearing locks for a process, lkb's were being removed from the astqueue list without clearing the field. If release_lockspace then happened immediately afterward, it could try to remove the lkb from the list a second time. Appears when process calls libdlm dlm_release_lockspace() which first closes the ls dev triggering clear_proc_locks, and then removes the ls (a write to control dev) causing release_lockspace().

2008-01-30dlm: use fixed errno values in messagesDavid Teigland1-2/+55
Some errno values differ across platforms. So if we return things like -EINPROGRESS from one node it can get misinterpreted or rejected on another one. This patch fixes up the errno values passed on the wire so that they match the x86 ones (so as not to break the protocol), and re-instates the platform-specific ones at the other end. Many thanks to Fabio for testing this patch. Initial patch from Patrick. Signed-off-by: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Fabio M.

2008-01-30dlm: close otherconsPatrick Caulfeld1-0/+2
This patch addresses a problem introduced with the last round of lowcomms patches where the 'othercon' connections do not get freed when the DLM shuts down. This results in the error message "slab error in kmem_cache_destroy(): cache `dlm_conn': Can't free all objects" and the DLM cannot be restarted without a system reboot.

2008-01-30dlm: bind connections from known local address when using TCPLon Hohberger1-1/+12
A common problem occurs when multiple IP addresses within the same subnet are assigned to the same NIC. If we make a connection attempt to another address on the same subnet as one of those addresses, the connection attempt will not necessarily be routed from the address we want. In the case of the DLM, the other nodes will quickly drop the connection attempt, causing problems. This patch makes the DLM bind to the local address it acquired from the cluster manager when using TCP prior to making a connection, obviating the need for administrators to "fix" their systems or use clever routing tricks.

Based upon the 2.4 kernel, the information presented in the Documentation/mips/GT64120.README file is outdated.
