Fix: ustcomm: application name uses the '-ust'-suffixed thread name
During the 2.13 development cycle, the compatibility pthread_setname_np
compatibility layer was fixed (see
0db3d6ee). Unfortunately, this had a
detrimental effect.
Upon the registration of an application to the session daemon, its name
is sent as part of the 'struct lttng_ust_ctl_reg_msg' registration
message. The application name is sampled using lttng_pthread_getname_np
during the preparation of the message.
However, when the listener thread is launched, its name is changed
early-on to add a '-ust' suffix (see
01f0e40c). This suffixed name is
sampled and sent to the session daemon. Since, until recently, the
pthread_setname_np had no effect on most configurations, this had no
consequence.
I noticed that this has a ripple-effect in the generation of some
path names. For instance, in per-pid mode, snapshots end-up with the
following hierarchy:
/home/jgalar/lttng-traces
└── Mercury
└── florence_jacques-
20210514-162630
└── snapshot-0-
20210514-162726-1

├── lol_2
├── lol_3
├── lol_4
├── lol_5
├── lol_6
├── lol_7
├── lol_8
├── lol_9
└── metadata
Notice how the 'hello' application presents itself with the '-ust'
prefix. For such a short application name, it doesn't really matter
much beyond repeating the 'ust' unnecessarily. However, longer
application names quickly become less readable as we lose four of
the 16 precious allowed characters for a process name.
The procname sampled during the execution of the constructors is
reused. My understanding is that the procname stored in the sock_info
is already used for the 'procname' context.
The resulting hierarchy becomes:

6a359b8a4006 ("Bump LTTNG_UST_ABI version from 8.1 to 9.0")
attempted to ensure that a session daemon linked against an old

This was done by increasing the major ABI version number, but
introducing LTTNG_UST_ABI_MAJOR_VERSION_OLDEST_COMPATIBLE (set to 8) as
a mean to allow session daemon to accept both major versions 8 and 9.
Unfortunately, changing LTTNG_UST_ABI_MAJOR_VERSION means the filenames
used for communication changed as well, meaning that applications linked
against older lttng-ust 2.12 cannot interact with lttng sessiond linked
against lttng-ust-ctl 2.13, which is unintended.

liblttng-ust-ctl: Implement SIGBUS handling
There is an issue with the security model of lib ring buffer (lttng-ust)
vs SIGBUS handling by consumer daemon. We do not handle SIGBUS in the
consumer daemon. An application using ftruncate on a ring buffer shm
could cause the consumer to be killed with SIGBUS.
Expose the relevant APIs to allow consumer daemon to handle SIGBUS.
It requires the user application (consumerd) to define the TLS sigbus
state with DEFINE_LTTNG_UST_SIGBUS_STATE(), and to invoke
lttng_ust_ctl_sigbus_handle() when a SIGBUS is received, passing the
address causing the SIGBUS (siginfo->si_addr) as parameter.
Internally, liblttng-ust-ctl uses sigsetjmp and siglongjmp to recover
from SIGBUS, and track all accesses to shared memory ranges within the
library.
This modifies the API of liblttng-ust-ctl, and requires the user
application to define the TLS sigbus state with
DEFINE_LTTNG_UST_SIGBUS_STATE(). It therefore needs to be introduced in
locked-step between lttng-ust and lttng-tools.

refactoring opens the door to have event class and instance not only in
different providers, but also in providers emitted within different
compile units and shared objects in the future.
For instance, if a .c includes the following headers:
#define LTTNG_UST_TRACEPOINT_CREATE_PROBES
#include "a.h"
#include "b.h"
where a.h contains:
LTTNG_UST_TRACEPOINT_EVENT_CLASS(a, myclass,
LTTNG_UST_TP_ARGS(int, anint),
LTTNG_UST_TP_FIELDS(
lttng_ust_field_integer(int, intfield, anint)
)
)
and b.h contains:
LTTNG_UST_TRACEPOINT_EVENT_INSTANCE(a, myclass,
b, myeventinstance,
LTTNG_UST_TP_ARGS(int, anint)
)
This is a localized API-breaking change introduced very early in the
2.13-rc cycle.
This changes the ABI exposed by the probe providers, so bump the probe
provider major version, and make newer lttng-ust reject old incompatible
major. We can do this because it is very early in the 2.13-rc cycle.

sequence type: use previous field for length if length_name is NULL
A common use-case for sequences is to use the field located immediately
prior to the sequence as sequence length.
The fact that the sequence type needs to explicitly contain its length
name ties the sequence type to where it is placed within the structure
fields, preventing re-use of the sequence type.
In order to reduce the memory footprint of the field descriptions and
allow re-use of common field types, special-case the NULL length_name to
use the field prior to the sequence as length.
This allows more efficient type descriptions without reducing the
overall flexibility of sequence layout.
