dlm: remove signal blocking

2013-08-12T20:22:43Z

The signal blocking was incorrect and unnecessary so just remove it. Signed-off-by: David Teigland

dlm: WQ_NON_REENTRANT is meaningless and going away

2013-07-30T14:24:24Z

dbf2576e37 ("workqueue: make all workqueues non-reentrant") made WQ_NON_REENTRANT no-op and the flag is going away. Remove its usages. This patch doesn't introduce any behavior changes. Signed-off-by: Tejun Heo Signed-off-by: David Teigland

dlm: Avoid LVB truncation

2013-06-26T16:38:02Z

For lockspaces with an LVB length above 64 bytes, avoid truncating the LVB while exchanging it with another node in the cluster. Signed-off-by: Bart Van Assche Signed-off-by: David Teigland

dlm: log an error for unmanaged lockspaces

2013-06-25T17:53:20Z

Log an error message if the dlm user daemon exits before all the lockspaces have been removed. Signed-off-by: David Teigland

dlm: config: using strlcpy instead of strncpy

2013-06-25T17:53:06Z

dlm: disable nagle for SCTP

2013-06-14T18:07:11Z

For TCP we disable Nagle and I cannot think of why it would be needed for SCTP. When disabled it seems to improve dlm_lock operations like it does for TCP. Signed-off-by: Mike Christie Signed-off-by: David Teigland

dlm: retry failed SCTP sends

2013-06-14T18:07:11Z

Currently if a SCTP send fails, we lose the data we were trying to send because the writequeue_entry is released when we do the send. When this happens other nodes will then hang waiting for a reply. This adds support for SCTP to retry the send operation. I also removed the retry limit for SCTP use, because we want to make sure we try every path during init time and for longer failures we want to continually retry in case paths come back up while trying other paths. We will do this until userspace tells us to stop. Signed-off-by: Mike Christie Signed-off-by: David Teigland

dlm: try other IPs when sctp init assoc fails

2013-06-14T18:07:11Z

Currently, if we cannot create a association to the first IP addr that is added to DLM, the SCTP init assoc code will just retry the same IP. This patch adds a simple failover schemes where we will try one of the addresses that was passed into DLM. Signed-off-by: Mike Christie Signed-off-by: David Teigland

dlm: clear correct bit during sctp init failure handling

2013-06-14T18:07:11Z

We should be testing and cleaing the init pending bit because later when sctp_init_assoc is recalled it will be checking that it is not set and set the bit. We do not want to touch CF_CONNECT_PENDING here because we will queue swork and process_send_sockets will then call the connect_action function.
