500c6e194b ctdb-scripts: Change statd-callout to be more scalable
Updating ctdb.tdb on each add-client, del-client and each delete
during notify was too ambitious.  Persistent transactions do not
perform well enough to do this.

Revert to having add-client and del-client create touch files.  Each
monitor event calls "statd-callout update" to convert touch files into
ctdb.tdb records.

Update testcases to do the "update" and add an extra test.

032441d9a2 ctdb-scripts: Fix a regression in statd-callout
Commit 4638010abb changed from using
gensub() to gsub() in awk.  However, it didn't halve the number of
backslashes in the target strings.  This is necessary because
backslash is used in gensub() target strings to allow substitution of
text matching parenthesised subexpressions.  This is not the case with
gsub().

So, halve the number of backslashes in the target string where gsub()
is used in statd-callout.  This is the only target string broken by
changes made by the above commit

39686f4505 ctdb-scripts: Fix tunable setup code by making it shell-agnostic
All tunables set in configuration are currently set to 0 on system
where /bin/sh is dash (and perhaps other non-bash shells).  dash puts
single quotes around all values in the output of the "set" builtin
command, whereas bash only puts them around values when something
needs to be quoted.  Tunables always have a simple integer value so
dash will quote them and bash won't.  The setup code currently passes
the raw value, including any quotes to "ctdb setvar ...".  This
command does no error checking on the input, so "'1'" is converted to
0.

Change the code so that the value is determined from the shell
variable and is independent of the "set" output.

ab51f283e7 ctdb-scripts: Call iptables/ip6tables directly from iptables_wrapper
Drops the iptables() and ip6tables() functions and, hence, the
hardcoding of paths /sbin/iptables and /sbin/ip6tables.  The latter
avoids problems on openSUSE where (for example) /usr/sbin/iptables is
used instead.

This means that locking around ip*tables commands is only done when
iptables_wrapper is called directly.  This is fine because the only
conflict is when "releaseip" or "takeip"/"updateip" events are run in
parallel.  The other uses in 11.natgw and 70.iscsi are in events where
there will be no collisions.

Making 11.natgw support IPv6 is unnecessary.  Just put a static IPv6
address on each interface - they're plentiful.

d0b2375c3d ctdb-scripts: Wait until IPv6 addresses are not "tentative"
There are a few potential failure modes when adding an IPv6 address.
It takes a little while of duplicate address detection to complete, so
wait for a while.  After a timeout, also need to check to see if
duplicate address detection failed - if it did then actually drop the
IP address.

This really needs some careful thinking.  If CTDB disappears on a node
but the node's IP addresses are still on interfaces then the above
failure mode could cause the takeover nodes to become banned.

7f377cf26e ctdb-scripts: Fix stack dumping when debugging hung scripts
There are parentheses missing that stop the default pattern from
matching commands with trailing garbage (e.g. "exportfs.orig").

A careful check of POSIX (and running GNU sed with --posix) suggests
that "\|" isn't a supported way of specifying alternation in a regular
expression.  Therefore, it is clearer to switch to extended regular
expressions so that this has a chance of being portable (even though
the point is to print /proc/<pid>/stack, which only works on Linux).

cb94eba157 ctdb-eventscripts: Remove NAT gateway "monitor" event
This event was introduced to handle misconfiguration.  For example,
where all nodes where configured as NAT gateway slaves.

However, this event can fail when there are performance issues and
capabilities can't be retrieved from a remote node.  The problem is
most likely with the remote node, so marking the local node UNHEALTHY
is probably a mistake.

Having a NAT gateway master node only matters in "ipreallocated", so
leave it to do the checking.  Given that a node will run
"ipreallocated" as part of the first recovery, this should cause
misconfigurations to be detected nice and early.

8a3be1f1a9 ctdb-eventscripts: Improve check in NATGW "startup" event
Although the dots in $CTDB_NATGW_PUBLIC_IP could probably only help
match an invalid public IP address, this is only executed once so do
as exact a check as possible.

Use CTDB_BASE instead of hardcoding /etc/ctdb.

Make the error message less redundant.
