Instead of the one when another syscall takes place while another is being
processed (in another CPU, but we show it serialized, so need to "interrupt"
the other), and also when finally showing the sys_enter + sys_exit + duration,
where we were showing the sample->time for the sys_exit, duh.
Before:
# perf trace sleep 1
<SNIP>
0.373 ( 0.001 ms): close(fd: 3 ) = 0
1000.626 (1000.211 ms): nanosleep(rqtp: 0x7ffd6ddddfb0) = 0
1000.653 ( 0.003 ms): close(fd: 1 ) = 0
1000.657 ( 0.002 ms): close(fd: 2 ) = 0
1000.667 ( 0.000 ms): exit_group( )
#
After:
# perf trace sleep 1
<SNIP>
0.336 ( 0.001 ms): close(fd: 3 ) = 0
0.373 (1000.086 ms): nanosleep(rqtp: 0x7ffe303e9550) = 0

Not used at all, we need just the entry_time to calculate the syscall

In the perf wiki todo-list[1], there is an entry regarding initial-delay
and 'perf trace'; the following small patch tries to fulfill this point.
It has been generated against the branch tip/perf/core.
It has only been implemented in the "trace__run" case.
Ex.:
$ sudo strace -- ./perf trace --delay 5 sleep 1 2>&1
...
fcntl(7, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
ioctl(7, PERF_EVENT_IOC_ID, 0x7ffc8fd35718) = 0
ioctl(11, PERF_EVENT_IOC_SET_OUTPUT, 0x7) = 0
fcntl(11, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
ioctl(11, PERF_EVENT_IOC_ID, 0x7ffc8fd35718) = 0
write(6, "\0", 1) = 1
close(6) = 0
nanosleep({0, 5000000}, NULL) = 0 # DELAY OF 5 MS BEFORE ENABLING THE EVENTS
ioctl(3, PERF_EVENT_IOC_ENABLE, 0) = 0
ioctl(4, PERF_EVENT_IOC_ENABLE, 0) = 0
ioctl(5, PERF_EVENT_IOC_ENABLE, 0) = 0
ioctl(7, PERF_EVENT_IOC_ENABLE, 0) = 0

By making function perf_evsel__append_filter() take a format rather than
an operator it is possible to reuse the code for other purposes (ex.
Intel PT and CoreSight) than tracepoints.

Both return errno, show the string associated then.
More work needed to capture the sched_attr arg to beautify it in turn,
probably using BPF.
Before:
0.210 ( 0.001 ms): sched_setattr(uattr: 0x7ffc684f02b0) = -22
After the patch, for this sched_attr, all other parms are zero, so not
shown:
struct sched_attr attr = {
.size = sizeof(attr),
.sched_policy = SCHED_DEADLINE,
.sched_runtime = 10 * USECS_PER_SEC,
.sched_period = 30 * USECS_PER_SEC,
.sched_deadline = attr.sched_period,
};
0.321 ( 0.002 ms): sched_setattr(uattr: 0x7ffc44116da0) = -1 EINVAL Invalid argument
[root@jouet c]# perf trace -e sched_setattr ./sched_deadline
Couldn't negotiate deadline: Invalid argument
0.229 ( 0.003 ms): sched_setattr(uattr: 0x7ffd8dcd8df0) = -1 EINVAL Invalid argument
[root@jouet c]#
Now to figure out the reason for this EINVAL.

The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.
But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.
So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

Noticed when the 'setsockopt' 'fd' arg wasn't being formatted via
the SCA_FD beautifier, so just remove the setting of "fd" args to
SCA_FD and do it when reading the syscall info, like we do for
args of type "pid_t", i.e. "fd" as the name should be enough as
the decision to use the SFA_FD beautifier. For odd cases we can
just do it explicitely.

We cannot limit processing stacks from the current value of the sysctl,
as we may be processing perf.data files, possibly from other machines.
Instead use the old PERF_MAX_STACK_DEPTH, the sysctl default, that can
be overriden using --max-stack or equivalent.

The test to check if the arg format had been read from the
syscall:sys_enter_name/format file was looking at the list of non-commom
fields, and if that is empty, it would think it had failed to read it,
because it doesn't exist, for instance, for the clone() syscall.
So instead before dumping the raw syscall args list check
IS_ERR(sc->tp_format), if that is true, then an attempt was made to read
the format file and failed, in which case dump the raw arg list values.

/proc/sys/kernel/perf_event_max_stack
There is an upper limit to what tooling considers a valid callchain,
and it was tied to the hardcoded value in the kernel,
PERF_MAX_STACK_DEPTH (127), now that this can be tuned via a sysctl,
make it read it and use that as the upper limit, falling back to
PERF_MAX_STACK_DEPTH for kernels where this sysctl isn't present.

Leave it alone so that it ends up assigned to SCA_PID via its type,
'pid_t', that will look up the pid on the machine thread rb_tree and
possibly find its COMM.

The variable is initialized and then conditionally set to a different

If one uses:
# perf trace --min-stack 16
Then it implicitly means that callgraphs should be enabled, and the best
option in terms of widespread availability is "dwarf".
Further work needed to choose a better alternative, LBR, in capable
systems.

Counterpart to --max-stack, to help focusing on deeply nested calls. Can
be combined with --duration, etc.
E.g.:
System wide syscall tracing looking for call stacks longer than 66:
# trace --mmap-pages 32768 --filter-pid 2711 --call-graph dwarf,16384 --min-stack 66
Or more compactly:
# trace -m 32768 --filt 2711 --call dwarf,16384 --min-st 66

With multiple threads, e.g. a system wide trace session, and one syscall is
midway in a thread and another thread starts another syscall we must print the
start of the interrupted syscall followed by ..., but that can't be done that
way when we use the --duration filter, as we have to wait for the syscall exit
to calculate the duration and decide if it should be filtered, so we have to
disable the interrupted logic and only print at syscall exit, duh.
Before:
# trace --duration 100

This way the print routine merely does printing, not requiring access to
the resolving machinery, which helps disentangling the object files and
easing creating subsets with a limited functionality set.

those definitions aren't available in the system headers.
