dlm: release socket on error

2008-07-14T18:56:59Z

It seems that `sock' allocated by sock_create_kern in tcp_connect_to_sock() of dlm/fs/lowcomms.c is not released if dlm_nodeid_to_addr an error. Acked-by: Christine Caulfield Signed-off-by: Masatake YAMATO Signed-off-by: David Teigland

The semaphore connections_lock is used as a mutex. Convert it to the mutex API. Signed-off-by: Matthias Kaehlcke Cc: Christine Caulfield Cc: David Teigland Cc: Steven Whitehouse Signed-off-by: Andrew Morton Signed-off-by: David Teigland

dlm: close othercons

2008-01-29T23:17:32Z

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.

dlm: bind connections from known local address when using TCP

2008-01-29T22:44:25Z

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.

[DLM] lowcomms: Do not muck with sysctl_rmem_max.

[DLM] Make dlm_sendd cond_resched more

2007-10-10T07:56:19Z

Under high recovery loads dlm_sendd can monopolise the CPU and cause soft lockups. This one extra and one moved cond_resched() make it yield a little more during such times keeping work moving. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] Fix lowcomms socket closing

2007-10-10T07:55:39Z

This patch fixes the slight mess made in lowcomms closing by previous patches and fixes all sorts of DLM hangs. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] More othercon fixes

2007-08-14T09:30:36Z

The last patch to clean out 'othercon' structures only fixed half the problem. The attached addresses the other situations too, and fixes bz#238490 Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] zero unused parts of sockaddr_storage

2007-08-14T09:29:27Z

When we build a sockaddr_storage for an IP address, clear the unused parts as they could be used for node comparisons. I have seen this occasionally make sctp connections fail. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse
