 2010/??/??	*** Release of OpenSSI 2.0.0rc1 ***
 
+2010/04/05	rogertsang <[email protected]>
+	* CVS Tags: OPENSSI-FC-1-9-6-PRE36
+
+	* IPC Messages:
+	- Fix memory corruption in sys_msgsnd() due to double kfree of
+	  msg_msgseg structures after sending to remote message queue.
+	  ssi_msgpack() already freed msg_msgseg. The second kfree is done in
+	  free_msg() prior returning to user space.
+	- Eliminate unnecessary struct msgbuf de-serialization in sys_msgsnd()
+	  at remote clients. The existing implementation de-serializes the
+	  user's buffer into msg_msg structure for the local message queue
+	  first. Then if it determines the queue is remote the msg_msg
+	  structure is re-serialized for transport. The new implementation
+	  skips all that and instead sends a copy of the user's buffer to the
+	  server.
+	- Remove ssi_msgpack() it is no longer used.
+	- Create ssi_load_msg() based on ipc/msgutil.c:load_msg() to load
+	  kernel space buffer.
+	- ssi_remote_msgrcv() to skip zero'ing of kernel space receive buffer.
+	  There is no security issue since the contents of buffer is not copied
+	  to user space unless the remote operation is successful.
