0c6a7db3ba ctdb-recoverd: Flatten update_flags_on_all_nodes()
The logic currently in ctdb_ctrl_modflags() will be optimised so that
it no longer matches the pattern for a control function.  So, remove
this function and squash its functionality into the only caller.

Although there are some superficial changes, the behaviour is
unchanged.

Flattening the 2 functions produces some seriously weird logic for
setting the new flags, to the point where using ctdb_ctrl_modflags()
for this purpose now looks very strange.  The weirdness will be
cleaned up in a subsequent commit.

37c26a9590 ctdb-tests: Separate custom cluster startup from test initialisation
Separate cluster startup from test initialisation for tests that start
the cluster with customised configuration.  In these cases the result
of the cluster startup is actually the point of the test.
Additionally, pubips.013.failover_noop.sh claims to have completed
test initialisation twice, which just seems wrong.

The result is:

* ctdb_test_init() takes one option (-n) to indicate when it should
  not configure/start the cluster

* New function ctdb_nodes_start_custom() accepts options for special
  cluster configuration, only operates on local daemons and triggers a
  test failure rather than a test error on failure.

be3065ea95 ctdb-tests: Make integration.bash pass shellcheck
Apart from the non-constant sourcing of include files.

Mostly avoidance of quoting warnings.

One subtle change is to simply pass "120" to wait_until_ready() to
stop warnings that it expects arguments but none are passed (both
SC2119 and SC2120).  There seems no way to indicate to structure
function argument handling so that shellcheck realises arguments are
optional.  In later shellcheck versions, disabling SC2120 for a
function also silences complaints about its callers... but not all of
our testing uses "later" shellcheck versions.

  The use of test_info() is pointless.

* Drop call to cluster_is_healthy()

  This is a holdover from when the previous test would restart daemons
  to get things ready for a test.  There was also a bug where going
  into recovery during the restart would sometimes cause the cluster
  to become unhealthy.  If we really need something like this then we
  can add it to ctdb_test_init().

0f04b8a70b ctdb-tests: Make integration.bash pass shellcheck
Apart from the non-constant sourcing of include files.

Mostly avoidance of quoting warnings.

One subtle change is to simply pass "120" to wait_until_ready() to
stop warnings that it expects arguments but none are passed (both
SC2119 and SC2120).  There seems no way to indicate to structure
function argument handling so that shellcheck realises arguments are
optional.  In later shellcheck versions, disabling SC2120 for a
function also silences complaints about its callers... but not all of
our testing uses "later" shellcheck versions.

  The use of test_info() is pointless.

* Drop call to cluster_is_healthy()

  This is a holdover from when the previous test would restart daemons
  to get things ready for a test.  There was also a bug where going
  into recovery during the restart would sometimes cause the cluster
  to become unhealthy.  If we really need something like this then we
  can add it to ctdb_test_init().

6e419dda71 ctdb: increase TasksMax limit, the systemd default is just 512
In 2015 systemd introduced a TasksMax which limits the number of processes in a
unit:

https://lists.freedesktop.org/archives/systemd-devel/2015-November/035006.html

The default of 512 may be too low in certain situations leading to vfork()
failing with errno=EAGAIN when trying to spawn lock-helper processes.

With the default for LockProcessesPerDB being 200 the increased TasksMax limit
should cover the problematic scenario.

Additional background: the failing vfork()s have been seen on production
clusters and were tracked down to being logged in the context of ctdb calling
tdb_repack().

f8f3d7954d ctdb-vacuum: Reschedule vacuum event if VacuumInterval has increased
The vacuuming integration tests set VacuumInterval to a very high
number to avoid vacuuming collisions.  This is done after the cluster
is healthy, so Samba will have already been started and vacuuming will
already be scheduled *at the default interval* for databases attached
by Samba.  This means that vacuuming controls used by vacuuming tests
can still collide with the scheduled vacuuming events.

Add some logic to reschedule a vacuuming event that has fired but
where VacuumInterval has increased since it was originally scheduled.
The increase in VacuumInterval is used as the time offset for
rescheduling the event.

Although this changes production behaviour for the convenience of
testing, the new behaviour is completely reasonable and obeys the
principle of least surprise.

716f52f68b ctdb-recoverd: Avoid dereferencing NULL rec->nodemap
Inside the nested event loop in ctdb_ctrl_getnodemap(), various
asynchronous handlers may dereference rec->nodemap, which will be
NULL.

One example is lost_reclock_handler(), which causes rec->nodemap to be
unconditionally dereferenced in list_of_nodes() via this call chain:

  list_of_nodes()
  list_of_active_nodes()
  set_recovery_mode()
  force_election()
  lost_reclock_handler()

Instead of attempting to trace all of the cases, just avoid leaving
rec->nodemap set to NULL.  Attempting to use an old value is generally
harmless, especially since it will be the same as the new value in
most cases.

c6c89495fb ctdb-daemon: Fix database attach deferral logic
Commit 3cc230b5ee says:

  Dont allow clients to connect to databases untile we are well past
  and through the initial recovery phase

It is unclear what this commit was attempting to do.  The commit
message implies that more attaches should be deferred but the code
change adds a conjunction that causes less attaches to be deferred.
In particular, no attaches will be deferred after startup is complete.
This seems wrong.

To implement what seems to be stated in the commit message an "or"
needs to be used so that non-recovery daemon attaches are deferred
either when in recovery or before startup is complete.  Making this
change highlights that attaches need to be allowed during the
"startup" event because this is when smbd is started.

319c93f0c6 ctdb-tcp: Do not stop outbound connection in ctdb_tcp_node_connect()
The only place the outgoing connection needs to be stopped is when
there is a timeout when waiting for the connection to become writable.
Add a new function ctdb_tcp_node_connect_timeout() to handle this
case.

All of the other cases are attempts to establish a new outgoing
connection (initial attempt, retry after an error or disconnect, ...)
so drop stopping the connection in those cases.

b83ef98c74 ctdb-tcp: always call node_dead() upcall in ctdb_tcp_tnode_cb()
ctdb_tcp_tnode_cb() is called when we receive data on the outgoing connection.

This can happen when we get an EOF on the connection because the other side as
closed. In this case data will be NULL.

It would also be called if we received data from the peer. In this case data
will not be NULL.

The latter case is a fatal error though and we already call
ctdb_tcp_stop_connection() for this case as well, which means even though the
node is not fully connected anymore, by not calling the node_dead() upcall
NODE_FLAGS_DISCONNECTED will not be set.

7cff3ed12c ctdb-tests: Use a local "ctdb shutdown" command to avoid a race
When "ctdb shutdown" is run with -n <N> it does not wait for the node
<N>'s ctdbd to go down but exits immediately.  This means that the
local_daemons.sh shutdown command can find the PID file still present
and then attempt the shutdown, but the daemon can have exited between
the check and the shutdown.  Although the test waits until the node is
disconnected, the transport is taken down just before the exit, so
this does not guarantee the daemon has exited.

A local shutdown command (no -n <N>) waits until the socket
disconnects and this happens *after* the PID file is gone, so this is
safe to use with the local_daemons.sh shutdown command.

POSIX says:

  If job control is disabled (see set, -m), the standard input for an
  asynchronous list, before any explicit redirections are performed,
  shall be considered to be assigned to a file that has the same
  properties as /dev/null. This shall not happen if job control is
  enabled. In all cases, explicit redirection of standard input shall
  override this activity.

ctdbd is backgrounded at startup, so the above causes stdin to be
redirected from /dev/null.  Enable job control to work around this.

pipe or a socket.

693080abe4 ctdb-scripts: Strip square brackets when gathering connection info
ss added square brackets around IPv6 addresses in versions > 4.12.0
via commit aba9c23a6e1cb134840c998df14888dca469a485.  CentOS 7 added
this feature somewhere mid-release.  So, backward compatibility is
obviously needed.

As per the comment protocol/protocol_util.c should probably print and
parse such square brackets.  However, for backward compatibility the
brackets would have to be stripped in both places in
update_tickles()...  or added to the ss output when missing.  Best to
leave this until we have a connection tracking daemon.

a6d99d9e5c ctdb-tcp: Close inflight connecting TCP sockets after fork
Commit c68b6f96f2 changed the talloc hierarchy such that outgoing TCP sockets
while sitting in the async connect() syscall are not freed via
ctdb_tcp_shutdown() anymore, they are hanging off a longer-running structure.
Free this structure as well.

If an outgoing TCP socket leaks into a long-running child process (possibly the
recovery daemon), this connection will never be closed as seen by the
destination node. Because with recent changes incoming connections will not be
accepted as long as any incoming connection is alive, with that socket leak
into the recovery daemon we will never again be able to successfully connect to
the node that is affected by this leak. Further attempts to connect will be
discarded by the destination as long as the recovery daemon keeps this socket
alive.

d0baad257e ctdb-tcp: Avoid orphaning the TCP incoming queue
CTDB's incoming queue handling does not check whether an existing
queue exists, so can overwrite the pointer to the queue.  This used to
be harmless until commit c68b6f96f2
changed the read callback to use a parent structure as the callback
data.  Instead of cleaning up an orphaned queue on disconnect, as
before, this will now free the new queue.

At first glance it doesn't seem possible that 2 incoming connections
from the same node could be processed before the intervening
disconnect.  However, the incoming connections and disconnect occur on
different file descriptors.  The queue can become orphaned on node A
when the following sequence occurs:

1. Node A comes up
2. Node A accepts an incoming connection from node B
3. Node B processes a timeout before noticing that outgoing the queue is writable
4. Node B tears down the outgoing connection to node A
5. Node B initiates a new connection to node A
6. Node A accepts an incoming connection from node B

Node A processes then the disconnect of the old incoming connection
from (2) but tears down the new incoming connection from (6).  This
then occurs until the originally affected node is restarted.

However, due to the number of outgoing connection attempts and
associated teardowns, this induces the same behaviour on the
corresponding incoming queue on all nodes that node A attempts to
connect to.  Therefore, other nodes become affected and need to be
restarted too.

As a result, the whole cluster probably needs to be restarted to
recover from this situation.

The problem can occur any time CTDB is started on a node.

The fix is to avoid accepting new incoming connections when a queue
for incoming connections is already present.  The connecting node will
simply retry establishing its outgoing connection.
