ctdb-scripts: Change default persistent DB for statd_callout_helper

2024-12-13T15:01:10+00:00

This database isn't use throughout CTDB, so name the it more
specifically.

Note that this might cause locks to be lost during upgrade to the
first version containing this change.

For testing, a different name is chosen to exercise related
functionality.

ctdb-tests: Update statd-callout tests to handle both modes

2024-12-13T13:57:32+00:00

Add support for shared_dir mode.

Instead of duplicating all of the tests, update them so they can be
wrapped.  Created new tests for shared_dir mode that source the
"original" tests.

ctdb-scripts: Add configuration variable CTDB_KILLTCP_USE_SS_KILL

2024-11-07T00:12:34+00:00

This allows CTDB to be configured to use "ss -K" to reset TCP
connections on "releaseip".  This is only supported when the kernel is
configured with CONFIG_INET_DIAG_DESTROY enabled.

From the documentation:

   ss -K has been supported in ss since iproute 4.5 in March 2016 and
   in the Linux kernel since 4.4 in December 2015.  However, the
   required kernel configuration item CONFIG_INET_DIAG_DESTROY is
   disabled by default.  Although enabled in Debian kernels since
   ~2017 and in Ubuntu since at least 18.04,, this has only recently
   been enabled in distributions such as RHEL.  There seems to be no
   way, including running ss -K, to determine if this is supported, so
   use of this feature needs to be configurable.  When available, it
   should be the fastest, most reliable way of killing connections.

For RHEL and derivatives, this was enabled as follows:

* RHEL 8 via https://bugzilla.redhat.com/show_bug.cgi?id=2230213,
  arriving in version kernel-4.18.0-513.5.1.el8_9

* RHEL 9 via https://issues.redhat.com/browse/RHEL-212, arriving in
  kernel-5.14.0-360.el9

Enabling this option results in a small behaviour change because ss -K
always does a 2-way kill (i.e. it also sends a RST to the client).
Only a 1-way kill is done for SMB connections when ctdb_killtcp is
used - the reasons for this are shrouded in history and the 2-way kill
seems to work fine.

For the summary that is logged, when CTDB_KILLTCP_USE_SS_KILL is "yes"
or "try", always log the method used, even the fallback to
ctdb_killtcp.  However, when set to "no", maintain the existing
output.

The decision to use -K rather than --kill is because short options are
trivial to implement in test stubs.

ctdb-tests: Fix test failure when tests are installed

2024-10-06T11:07:05+00:00

This currently works when tests are run in-tree.

However, when installed, use of an incorrect variable means it fails
to find statd_callout in the tests/ subdirectory.  Switch to using the
correct variable.

ctdb-tests: Add missing quotes in test output

2024-10-06T09:52:35+00:00

These should have caused test failure since commit
ef921bdbdbacecf39ee2a1851f16dbba62175fcc.  However, the test failure
occurred in a sub-shell, which covered the failure.  So, add an error
exit if the sub-shell fails.

While here, add an error exit for another potential uncaught
sub-shell-related failure in a related test.
