Remove runtime dependency on liburcu shared objects

Author Date: 2020-11-11 22:28:06 UTC

Remove runtime dependency on liburcu shared objects

Remove the runtime dependency on:

- liblurcu-bp.so
- liblurcu-cds.so
- compat futex code.

By integrating those into the lttng-ust project.

For rculfhash, only the minimum pieces needed by lttng-ust are
integrated (no auto-resize, no accounting).

lttng-ust still requires liburcu at build time for header dependencies.

Fix: ustctl_release_object: eliminate double-close/free on error

Author: Mathieu Desnoyers
Author Date: 2020-09-22 20:38:51 UTC

Fix: ustctl_release_object: eliminate double-close/free on error

When ustctl_release_object returns an error, it is unclear to the caller
what close/free side effects were effectively performed and which were
not. So the only courses of action are to either leak file descriptors
or memory, or call ustctl_release_object again which can trigger double
close or double free.

Fix this by setting the file descriptors to -1 after successful close,
and pointers to NULL after successful free.

ABI: refuse non-matching ABI minor version on event registration

Author: Jonathan Rajotte

ABI: refuse non-matching ABI minor version on event registration

In scenarios where a lttng-tools 2.8 (lttng-ust 2.8) stack is running
and an application linked against a lttng-ust 2.7, event registration
will fail on fields size validation [1]. This is not expected based on
the ABI versioning exposed by lttng-ust 2.7 (6.0) and lttng-ust 2.8
(6.1).

The same happen if the scenario is reversed.

This is the result of a change in _ustctl_basic_type.

2.8 introduced enumeration to _ustctl_basic_type. The defined padding is
of 296 while the new union member is 312 (310 of real data + 2 for
alignment) pushing the structure size to 312 instead of the previous
296. This should have been an major ABI break but until now the problem
did not surface.

To prevent this, refuse non matching minor version. No need to check for
particular major,minor version since only 6.0 (ust 2.7) and 6.1 (ust
2.8) exist until a major ABI break.
