[DLM] lowcomms style

2007-05-01T08:11:51+00:00

Replace some printk with log_print, and fix some simple cases of lines
over 80.  Also, return -ENOTCONN if lowcomms_start fails due to no local
IP address being available.

[DLM] Lowcomms nodeid range & initialisation fixes

2007-05-01T08:11:41+00:00

Fix a few range & initialization bugs in lowcomms.
- max_nodeid is really the highest nodeid encountered, so all loops must include
it in their iterations.
- clean dlm_local_count & connection_idr so we can do a clean restart.
- Remove a spurious BUG_ON

[DLM] Fix dlm_lowcoms_stop hang

2007-05-01T08:11:38+00:00

When you attempt to release a lockspace in DLM, it will hang trying to down a
semaphore that has already been downed.  The attached patch fixes the problem.

[DLM] Consolidate transport protocols

2007-05-01T08:11:23+00:00

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.

[DLM] Add support for tcp communications

2006-11-30T15:35:00+00:00

The following patch adds a TCP based communications layer
to the DLM which is compile time selectable. The existing SCTP
layer gives the advantage of allowing multihoming, whereas
the TCP layer has been heavily tested in previous versions of
the DLM and is known to be robust and therefore can be used as
a baseline for performance testing.

[DLM] fix iovec length in recvmsg

2006-10-20T13:13:10+00:00

I didn't spot that the msg_iovlen was set to 2 if there
were two elements in the iovec but left at zero if not :(

I think this might be why bob was still seeing trouble.

[DLM] fix iovec length in recvmsg

2006-10-12T21:11:33+00:00

The DLM always passes the iovec length as 1, this is wrong when the circular
buffer wraps round.

[DLM] move kmap to after spin_unlock

2006-08-11T13:44:00+00:00

Doing the kmap() while holding the spinlock was causing recursive spinlock
problems.  It seems the kmap was scheduling, although there was no warning
as I'd expect.  Patrick, do we need locking around the kmap?

[DLM] init rwsem earlier

2006-06-19T13:15:38+00:00

The nodeinfo_lock rwsem needs to be initialized when the module is loaded
instead of when the dlm is first used.
