9cde594006 the posix.4 name for the priority field is sched_priority
not __sched_priority

a650497680 as an optimization for when we want to send multiple tickles at a time
let the caller create the sending socket and use a single socket instead 
of one new one for each tickle.
pass a sending socket to ctdb_sys_send_tcp()

ctdb_sys_kill_tcp is not longer used so remove it

set the socketflags for close on exec and nonblocking in the helper that 
creates the sockets instead of in the caller

add a helper to create a sending socket to send tickles from

823b7d4a5f rename killtcp->fd to killtcp->capture_fd
we might want to have two sockets attached to the killtcp structure
one for capturing and a second one for sending  so we dont have to 
create a new socket for each tickle we want to send

4b6d9485ab ctdb killtcp no longer takes a <numrst> argument to control how many
times to try the reset.

the reset retry attempt is now handled inside the daemon

update the 60.nfs script and remove this parameter that is no longer 
used

d81bca2072 make it possible to specify how many times ctdb killtcp will try to RST
the tcp connection

change the 60.nfs script to run ctdb killtcp in the foreground so we 
dont get lots of these running in parallel when there are a lot of tcp 
connections to rst

a859723912 nicer handling of DISCONNECTED flag when we update the node flags from
a remote message

69f3a09e6f when a remote node has sent us a message to update the flags for a node,
dont let those messages modify the DISCONNECTED flag.

the DISCONNECTED flag must be managed locally since it describes whether 
the local node can communicate with the remote node or not

b871c3e365 a better way to fix the DISCONNECT|BANNED vs DISCONNECT bug
(This used to be ctdb commit 5c638d7731c5a268de02d3a37828ac7aec9a12de)
2007-07-09 12:55:15 +10:00

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
