e3b6d1e511 if the node is inactive i.e. banned or disconnected then that node is 
not participating in the cluster

if a client tries to attach to a database while the node is inactive,  
return an error back to the client and fail the attach

b47384d57a when a node becomes banned its databases are no longer part of ctdb 
and it should thus no longer serve any database access calls until it 
has been reintroduced into the cluster.

when becoming banned,   reset the local generation id to 1   to prevent 
any further database access calls from other nodes from being processed.

8b06fc7284 change the structure used for node flag change messages so that we can 
see both the old flags as well as the new flags (so we can tell which 
flags changed)

send the CTDB_SRVID_RECONFIGURE messages to connected nodes only, not to 
every node, connected or not, in the cluster.


in the handler inside the recovery daemon which is invoked for node flag 
change messages, only do a takeover_run() and redistribute the ip addresses IF it was the 
disabled or the unhealthy flags that changed. Also send out the cluster 
reconfigured message in this case.
If any of the other flags changed we dont need to do the takeover_run(0 
here since that will be done during recovery.

4e4dd6b886 when we shutdown the service due to receiving a 'ctdb shutdown' command 
from the administrator, log this as 'Received SHUTDOWN command. Stopping 
CTDB daemon.'   so that the administrator will know when looking at the 
log 'why' the ctdb service was terminated.

Previously the only thing logged was 'shutting down' which is not 
detailed enough.

7e1f840c8d if a public address has already been taken over by a node, then let that 
public address remain at that node until either the node becomes 
unhealthy or the original/primary node for that address becomes healthy 
again.


Othervise what will happen is 
1, if we ban a node,   the banning code immediately does a 
takeover_run() and reassigns the public address to a different node in 
the cluster.
2, a few seconds later (at most) the recovery daemon will detect that 
the number of nodes has shrunk and will initiate a recovery.
During the recovery  the public address would again be assigned to a 
node, this time a different node.

6d5af34024 from Chris Cowan 
patches to smnotify to make it compile under AIX.

On AIX, we need to specify $(POPT_OBJ) explicitely

On AIX we can not use the -C flag to rpcgen since it is not implemented

On AIX we must explicitely force an #include of rpc/rpc.h in the idl 
file since rpcgen does not automatically add it to the generated files

9c216d0d76 when we want to kill a tcp connection we stored the connection 
description (src + dst sockaddr_in) in a linked list.
everytime we receive a captured packet from the network we had to walk 
this list in linear time to see if the packet matched a connection we 
wanted to RST.
which wouldnt scale very well.


replace the linked list with a redblack tree that is indexed by
src address, src port,  dst address,   dst port
to make checking whether the packet belongs to a connection we want to 
RST very fast and scalable


the reason we need to capture packets when we want to kill a TCP 
connection is because we must wait for an ACK coming back from the 
remote host  so that we can learn which sequence number to use in the 
RST.
Most tcp today will ingore any and all RST segments unless the 
sequencenumber lies exactly on the right edge of the window to make 
spoofing RST a little bit more difficult.

c1bfda5772 add a tree insert function that takes a callback fucntion to populate

rename the tree->tree pointer to tree->root  since this is supposed to 
point to the root of the tree

49f0317b21 when inserting data in the tree, if there was already a node with the 
same key then replace the data in the node with the new data and return 
the pointer to the previous data held in the node.

this allows a caller to avoid having to first check if a node already 
exists before inserting a possibly duplicate/colliding entry and lets 
the caller do whatever it needs to do after the fact.

fca90ce3c3 updated ctdb tickle management 
there is an array for each node/public address that contains tcp tickles

we send a TCP_ADD as a broadcast to all nodes when a client is added

if tcp tickles are removed, they are only removed immediately from the 
local node.
once every 20 seconds a node will push/broadcast out the tickle list for 
all public addresses it manages.   this will remove any deleted tickles 
from the remote nodes

server

add a control to send the full list of every tickle that is registered

to the next node in the list

69f3a09e6f when a remote node has sent us a message to update the flags for a node,

3499c8c673 when checking the nodemap flags for consitency while monitoring the 
cluster,   we cant check that both the BANNED and the DISCONNECTED flags 
are both set at the same time   since if a node becomes banned just 
before it is DISCONNECTED   there is no guarantee that all other nodes 
will have seen the BANNED flag.

So we must first check the DISCONNECTED flag only   and only if the 
DISCONNECTED flag is not set should we check the BANNED flag.


othervise this can cause a recovery loop while some nodes thing the 
disconnected node is DISCONNECTED|BANNED and other think it is just 
DISCONNECTED
