usdt parser: fix memory leak in provider and probe htabs
The prvmap and prbmap hashtable implementation was lacking code to
ensure that entries are freed when the hashtables are destroyed. In
addition, the pvp->pmap hashtables were also not cleaned up.

dlibs: report missing CTF and BTF data for vmlinux
If the kernel is not compiled with CTF and/or BTF enabled, DTrace will
not work. This used to result in an assert, which is rather harsh and
not user friendly. We now report a nice error.
Doing this in the pragma 'depends on' handling may seem odd but that is
where the initial type data load is triggered. If for some strange
reason no dlibs exist (and thus no 'depends on' are encountered), the
compiler will complain about missing type information anyway.

-----------
Fix stack-skip counts for caller and stackdepth
Apparently, when we call the BPF get_stack() helper function,
it generally knows how many frames to skip to get the real kernel
stack. For fentry/fexit, however, this is apparently not the case,
and commit bc65cb44d
("cg: allow providers to specify a skip count for stack retrieval")
added the ability to skip frames for fentry/fexit probes.
When this "skip" is needed, however, it must must be even deeper
when we descend further frames, such as when we call dt_bpf_*()
precompiled functions.
Add this support for dt_bpf_caller() and dt_bpf_stackdepth().
That is, if there are stack-skip frames, skip yet one more frame
when inside a bpf/get_bvar.c function.
Note that we declare the skip count volatile. The compiler might
optimize code that uses the STACK_SKIP value, but we will subsequently
perform relocations that adjust this value.

test: caller and stackdepth tests for fbt provider
We will introduce a set of tests for the caller and stackdepth
built-in variables for a wide selection of providers.
For the caller test, we will essentially call
stack(2);
sym(caller);
and then compare the caller to the second stack frame using
the new script check_caller_to_stack2.awk.
For the stackdepth test, we will essentially call
printf("%d\n", stackdepth);
stack();
and then compare the stackdepth to the reported frames using
the new script check_stackdepth_to_stack.awk.
In this patch, introduce tests for the fbt provider, along with
the support scripts they need. Subsequent patches will handle
other providers.
The old tst.caller2.d and tst.stackdepth2.d, which tested fbt,
become obsolete. Remove them.

Also, a few old tests, which tested caller and stackdepth using the
dtrace provider, are now superfluous given the new, provider-named
tests. The old tests were extremely lenient -- e.g., simply
checking that these built-in variables were not -1, even though
both variables are unsigned anyhow!

Since the callback is invoked during trampoline creation, rejection
must result in a compilation error. The callback is responsible for
this. If it returns, the clause is accepted.

rawfbt: selectively allow return() in clauses
The return() action is only allowed in clauses associated with a rawfbt
probe on a function listed in /sys/kernel/debug/error_injection/list.
Use a reject_clause() callback in the rawfbt provider to enforce this.
The list of allowed function is only initialized the first time it is
needed, and its content will be stored in a hashtable for faster
lookup beyond the first.

The dt_bpf_map_lookup_fd(dtp->dt_aggmap_fd, &cpu) call that is used to
snap or truncate aggregations takes a few milliseconds, which seems all
right. For large systems (e.g., 100 CPUs) and many truncations (e.g.,
tst.trunc.d, etc.), however, a trunc() might end up costing a minute on
the consumer side, which is unreasonable and causes such tests to time
out. The run time is due almost exclusively to looking up the per-CPU
agg map ID.

test: Mimic dtrace arithmetic more closely for avg/stddev
The multicpus test checks that data from multiple CPUs is aggregated
properly. Operations like avg() and stddev() require division.
DTrace uses integer division, while awk does not.
Change the awk check to truncate intermediate results after division.
In practice, intermediate results are typically integer values anyhow.
So the test has generally passed. Non-integer values could arise if,
for example, CPUs are not numbered consecutively. More typically,
there may be a problem that the profile probe is not firing on every
expected CPU. So a test failure probably was a sign of a problem,
but that's a different problem, one beyond the scope of this test.

test/utils: add more reliable "get remote address" approach
The current approach of looking for remote addresses
is brittle and fails in many environments; it checks the
default route gateway and looks for open ports in the TCP
case.
We can however achieve the same goal reliably by creating
a network namespace on the system and configuring either
IPv4 or IPv6 addresses on the namespaced and local veth
interfaces that support communication between namespaces.
If a tcp port is required, start sshd to listen on that port.
Teardown of network namespaces is managed in the toplevel runtest.sh to
ensure that network namespaces are removed after test completion for all
cases: success, failure and timeout.
Move the get_remote.sh script to test/utils also as it
seems a more natural location.
One issue - this cannot be run on a local system with
a VPN running as the VPN connection is pretty aggressive
in disconnecting/reconnecting when spotting a link-up event
associated with the global netns side of the veth. However
in my experience the remote IP tests do not work reliably
in that environment anyway.

libproc: make Psystem_daemon() detect modern systemd properly
Psystem_daemon() is used when carrying out shortlived grabs to detect
whether a process is too risky to carry out invasive grabs of (you wouldn't
usually want to stop syslogd or, God forbid, try to ptrace PID 1, unless
explicitly requested via -p: the process just coming up in routine probe
firing is not enough).
This has two code paths: a reliable one for systemd systems (which checks to
see if the process is in the system slice, which contains precisely and only
system daemons), and an unreliable one for other systems (which does the old
Unix approach of consdering anything in the user uid range or with a TTY or
with open standard FDs to TTYs to be not system daemons, and everything else
to possibly be one).
We were checking to see if a system was systemd by looking for the systemd
cgroup hierarchy name in any of the victim process's cgroups. This was
reliable back in the days of cgroups v1, but alas in v2 where systemd runs
all the cgroups if it runs any and there are no longer multiple hierarchies,
systemd no longer names its cgroups this way and the test fails, causing us
to fall back to the unreliable pre-systemd approach.
Use a more reliable approach to detect systemd, the same approach used by
sd_booted() in libsystemd; check for the existence of the
/run/systemd/system directory. Fix slice detection to work in the absence
of a systemd hierarchy name (but keep it working when a hierarchy name
*is* present, for older systems), and everything else works unchanged.
We also arrange to fall back to the old code for any processes that are
entirely outside of systemd management: this covers kernel threads,
the occasional process that is part of systemd itself, and also processes
running using Delegate= to give over their subtree's cgroup management to
something else.

cat the output files. If there is any delay in handling the signal,
the last output will be missing.
Have the processes terminate themselves when their last output is
flushed; then wait for those processes. Also, skip testing altogether if
there is only a single processor to run the two, hard-spinning processes.

Optimize USDT discovery a little
We want to reduce the performance cost of USDT discovery if possible.
Specifically, a number of statements -- with probe descriptions such as
"dtrace:::BEGIN" that could never specify USDT probes -- will not get
their clause flags set with DT_CLSFLAG_USDT_EXCLUDE. So these statements
get considered unnecessarily during periodic probe discovery.
Therefore:
*) Expand ignore_clause(dtp, n, uprp) to support the case uprp==NULL.
This case is independent of any knowledge of a specific underlying
probe.
*) During probe discovery, check ignore_clause(dtp, i, NULL). This
sets the DT_CLSFLAG_USDT_[INCLUDE|EXCLUDE] flag and allows faster
exclusion of statements that do not need to be reconsidered.
To take advantage of this optimization, users should specify providers.
E.g., instead of "BEGIN" (which could conceivably be a USDT probe),
specify "dtrace:::BEGIN".

support stapsdt ELF-note-defined static probes
As well as using dtrace -G to generate USDT probes, programs and
libraries may have added static probes via stapsdt ELF notes.
Read ELF notes from binaries from /proc/ maps associated with processes
and parse them to retrieve uprobe address and argument-related info
to create the associated uprobe.
Probe arguments can be either constants, register values or dereferences
or dereferences from register values (plus offset), identical to the
updated USDT ELF note handling.
A new provider - stapsdt - implements this support, as stapsdt probes do
not dynamically register themselves with DTrace. This makes them less
powerful than DTrace-based USDT probes, but they do exist in programs and
libraries so should be supported.
As well as supporting ELF-note stapsdt defined probes in programs and
libraries, this patch supports dynamically-created probes that
are created via libstapsdt [1]. libstapsdt allows dynamic languages
like python to declare and fire probes by dynamically creating
a memfd-based shared library containing ELF notes for the probes.
With these changes we can also trace these probes. This is very
useful since libstapsdt has python, NodeJS, go and luaJIT bindings.

test: Fix post processing of return-action override-pid tests
In commit ee8c066e8 ("rawfbt: selectively allow return() in clauses"),
tests were introduced to check that return values are overwritten. A
pid check value is output and used to facilitate comparisons to a .r
results file.
The post processing logic was flawed in two respects:
1 The check value was being pulled from the "01" entry. Therefore,
the "00" entry, typically appearing first, would not be converted.
2 Values were not sorted. Sometimes this means the disorder just
described would be avoided and the test would pass. Mostly,
it means that behavior can be erratic.
Sort results and use the "00" pid value for converting test results.
Add $dt_flags to the $dtrace line while we're at it.

Add function name to underlying return probes
In commit 35a4f05c2
("Add support for pid function "-" with absolute offset"),
function names were removed from underlying probe descriptions.
That was so that pid absolute offset probes (pid$pid:a.out:-:$absoff),
with function "-", could sit on the same underlying probes as
pid$pid:$mod:$fun:entry, pid$pid:$mod:$fun:$off, and USDT probes.
While that made sense for those probes, it did not make sense for pid
return probes: their underlying probes, all with probe name "return",
are no longer distinguishable. Further, there was no need for any such
change, since no other probes will have the same underlying return probe.
Name underlying return probes with function name.

Snapshot aggregations just in time
Currently, dtrace periodically calls dtrace_work(), which in turn calls
dtrace_consume(), which among other things calls dtrace_aggregate_snap().
But aggregations are kept in entirety in the kernel's BPF maps. There
is no need to snapshot the aggregations into user space unless we're
actually going to do something with aggregations.
Snapshot aggregations just in time -- that is, if there is a clear(),
trunc(), or printa() or if aggregations are to be printed at the end
of a dtrace session.
Skip the aggrate-slow test. Just-in-time snapshots mean the semantics
of aggrate have changed. A fast aggrate means nothing. A slow aggrate
means we are supposed to use stale aggregation data, which would be
baffling. A future patch is advised to deprecate aggrate entirely.

dvar: ensure dynamic variables cannot overwrite eachother
As Eugene discovered, it was possible for dynamic variables (elements
of associative arrays and TLS variables) to overwrite eachother. The
problem turns out to be due to the implementation of the BPF helper
bpf_map_update_elem(). In order for the update to be seen as an atomic
operation, it does not update the value of the map element in-place but
instead allocates a new element and places it in front of the old one
before it removes the old one. The result is that the address of the
map element changes as a result of the bpf_map_update_elem() call.
Fortunately, we can just assign the address of the map element in the
value that we obtained using bpf_map_lookup_elem() because that gives
us a pointer to the map value, and we can assign directly into it.
In other words, we do not need the 2nd bpf_map_update_elem() anyway,
and since that was the culprit, removing it resolves the issue.
Test included.

The trace("") action would dump a series of 0x00 bytes (strsize of

behaviour, it does not really make any sense to do so. The trace
action is described as printing data as a string if possible, and a
block of 0-bytes can certainly be printed as an empty string.

string: ensure string size is handled correctly
A string is defined as a character array of size strsize. Strings
that are less that strsize in length are terminated by a NUL byte.
This implies that the NUL byte is part of the array and therefore,
strsize is indeed the size of the array and not the maximum number
of characters in the string.
Tests are adjusted to reflect this behaviour.

Use a consistent type for dtrace_consume()
For a long time, the type of dtrace_consume() has been
- int according to libdtrace/dtrace.h
- dtrace_workstatus_t according to libdtrace/dt_consume.c
With some recent compilers, however, this triggers the warning (redacted
here):
libdtrace/dt_consume.c:3041:1: warning: conflicting types
for ‘dtrace_consume’ due to enum/integer mismatch;
have ‘dtrace_workstatus_t(...)’ [-Wenum-int-mismatch]
3041 | dtrace_consume(...)
| ^~~~~~~~~~~~~~
In file included from libdtrace/dt_impl.h:14,
from libdtrace/dt_consume.c:16:
libdtrace/dtrace.h:210:12: note: previous declaration of
‘dtrace_consume’ with type ‘int(...)’
210 | extern int dtrace_consume(...)
| ^~~~~~~~~~~~~~
which is a nuisance.
Note that dtrace_consume() is called from only one site, where its
value is compared to DTRACE_WORKSTATUS_ERROR, which is an argument
for the dtrace_workstatus_t type.
On the other hand, dtrace_consume() is defined to return a variety
of values, like 0, dt_set_errno(), and dt_consume_cpu(), all of which
are int, but also DTRACE_WORKSTATUS_OKAY, DTRACE_WORKSTATUS_ERROR,
and rval, all of which are dtrace_workstatus_t. But then rval itself
is set to dtrace_workstatus_t dt_consume_begin() or int
dt_consume_cpu(). So, there is simply no consistency here.
Having the prototype be dtrace_workstatus_t requires some amount
of code refactoring.
Just change the definition to int and clean up the warning.

examples: Add "language features" demo scripts
The idea is to have lots of short scripts, each illustrating a
D language feature.
The numbering scheme serves two purposes:
*) the scripts are more or less in ascending order
of difficulty, although that's admittedly a tricky
concept in such a multi-dimensional space
*) there is some grouping of themes -- e.g.,
"introduction", "providers", "built-in variables", etc.
The combination of comments and code is intended to help either
a human user or an AI bot to learn how to use the D language.
Other examples have been based on functional objectives (doing
simple but useful tasks). These new examples are based on language
features. A future set of examples could be based on errors! That
is, the scripts generate errors of different sorts that we would
illustrate (and explain how to fix).

Use rawfbt for this probe to revert back to kprobes in this case.
Other fbt probes may also be impacted, but this case showed up in testing.

cg: fix offset for > 8 bit bitfields in dt_cg_ctf_offsetof()
The tcp provider uses dt_cg_tramp_get_member() to retrieve the
offset of the sk_protocol field in struct sock. However it
returns the wrong value on UEK6 since it is an 8-bit bitfield.
>From pahole we see:
unsigned int __sk_flags_offset[0]; /* 560 0 */
unsigned int sk_padding:1; /* 560: 0 4 */
unsigned int sk_kern_sock:1; /* 560: 1 4 */
unsigned int sk_no_check_tx:1; /* 560: 2 4 */
unsigned int sk_no_check_rx:1; /* 560: 3 4 */
unsigned int sk_userlocks:4; /* 560: 4 4 */
unsigned int sk_protocol:8; /* 560: 8 4 */
In other words it is really at offset 561 but because we just
lookup the member offset and not the member type offset we get the
wrong value for the sk_protoocol.
This in turn causes tcp state-change probes (and in-progress UDP
probes) to not fire since we verify that sk_protocol == IPPROTO_TCP.
The fix is to look up the member _type_ offset and add it to the
bit offset we get for the member itself. With this in place the
state-change probes fire, but the local tcp tests still fail due
to separate issues with the tcp:::accept-established probe.
This issue is not seen on more recent kernels because sk_protocol
becomes a __u16 as the number of protocols exceeds 256.

tcp provider: use __ip_queue_xmit() as it is non-static on 5.4
On older kernels - 5.4 to be precise - ip_queue_xmit() is a static
function, so it is better to instrument __ip_queue_xmit() as it
is extern so not prone to optimization on 5.4 and later kernels.
With this change, the following previously-failing-on-UEK6U3 tcp tests
pass (and continue to pass when tested on an upstream kernel):
tst.ipv4localtcp.sh
tst.ipv4remotetcp.sh
tst.ipv6localtcp.sh
More work is required to fix up the tcpstate tests for UEK6U3.

tcp provider: support tcp:::accept-established in absence of skb
On a 5.4 kernel, the function we instrument for tcp:::accept-established
(tcp_init_transfer()) does not have a struct sk_buff * as argument;
that does not appear until 5.10. As a result we need to fake up
the IP and TCP headers from the TCP socket. We can reuse existing
code (ensuring to mark accept-established correctly as an _INBOUND
probe) once we fix up references in ip.d to be arg6 and not arg7 (this
parameter is used to mark a probe point as inbound, outbound or as a
state change). We need to ensure that args[2] is translated from
a __dtrace_tcp_void_ip_t * to get this to work for the IP header.
For the TCP header we need a similar solution; add a
__dtrace_tcp_void_tcp_t type and translate from either the tcp header
passed in (if non-null) or use arg3 (the socket) to fill out the TCP
header info. We can get the ports, seq/ack and because we know that
only accept-established is used we know the flags will just be an
ACK.
With this in place (along with previous fixes for the TCP provider)
the TCP state-related tests finally pass on a 5.4 kernel.

Add more robust mechanism to skip tracepoint common fields
In dt_tp_event_info(), we parse tracepoint format files -- e.g.,
/sys/kernel/debug/tracing/events/*/*/format. Specifically, we
are interested in the argument descriptions found in the file,
but we are interested in skipping over "common fields."
The mechanism we used for this purpose was, in dt_provider_tp.c,
to hardwire the number of fields to skip to SKIP_FIELDS_COUNT=4,
assuming the common fields would always be type, flags, pid, and
preempt_count.
This is hardly a robust mechanism. For example, consider
https://kernel.googlesource.com/pub/scm/linux/kernel/git/rt/
linux-rt-devel/+/refs/tags/v5.9.1-rt20-patches/patches/
preempt-lazy-support.patch
which introduces a preempt_lazy_count common field (on top of
others). Recent dtrace testing on RHCK 5.14 indicates widespread
test failures due to this problem.
Implement a more robust mechanism.
Specifically, instead of skipping a hardwired (SKIP_FIELDS_COUNT=4)
number of common fields, look for "common_" names. E.g., in
kernel/trace/trace_events.c in trace_define_common_fields(), we
see the macro __common_field() is used to define common fields,
and the names are prepended with "common_".

test: Add trigger for more predictable run time
The test had no trigger and so waited haphazardly for the write:entry
probe to fire. This typically worked, but led to variable run times
and even, though rarely, a test timeout and failure.
Add a trigger for more reproducible and typically shorter run times.

enum: support declarations with a trailing comma
When doing python tracing, it was recently observed that #include'ing
a file with enum declarations with trailing commas fails; this is
due to the D grammar being strict about the last enumerator value
not having a trailing comma. So
enum foo {
BAR,
BAZ
};
is permitted, but
enum foo {
BAR,
BAZ,
};
is not. The latter pattern is used quite frequently in #include
files, especially where conditional compilation of some enum
values is done.
Relax this constraint and add a test to validate that D compilation
succeeds with the trailing comma in an enum declaration.

parser: fix parser debugging yet again
The interaction between YYDEBUG and the yydebug extern variable has
changed repeatedly in the various iterations of flex and bison. The one
thing that is consistent is that yydebug is not used if YYDEBUG is unset
or set to 0; if it's set to 1, the parser skeleton defines it for you.
So (now that -fno-common is on by default) dl_lex.l should not be
defining yydebug itself, and dt_impl.h should only be declaring it
extern if YYDEBUG is 1.
With this in place, we link and run with the parser debugger set to the
expected state when compiling with YYDEBUG 1, YYDEBUG 0, and YYDEBUG
unset.

lexer: the things inside an enum { ... } declaration are identifiers
The code in dt_lex.c:id_or_type() tries to figure out if something is an
identifier or not: if it cannot prove it is an identifier, it concludes
it must be a type name, which later triggers a search for said type (or
identifier) which eventually reaches (expensively) across the entire
kernel CTF. Usually this is what we want, since we use type names that
actually reside in the kernel extensively and do not expect to have to
decorate all of them with `. But if this misfires bad things can happen.
In the case of enums, existing code in dt_decl.c checks for duplicate
identifiers, and carefully avoids considering code outside the C and D
dicts to be duplicates: but if id_or_type() concludes this enumerator is
probably a type name, we'll import the thing we find even if it's an
identifier, and then conflict. Enumerators cannot be type names, so this
must always be wrong (if we actually do put a type name in there,
dt_parser.c will correctly reject it no matter what the lexer says).
So add yet another piece of parser context identifying when we are
inside the { } in an enum (we set it to 1 when the enum is seen, then
bump it when the braces are seen, so if it's 2 we are in the relevant
context; it is reset to 0 on every ;), then use that to forcibly declare
everything seen inside enums an identifier without trying to chase it
down

A couple of new tests verifying that type names appearing in enums are

and a renaming of the D_UNKNOWN tests now that libctf can be assumed

emits a good description of this failure than the converse.

cg: fix masking of lower 32 bits
The "and %r0, 0xffffffff' instruction does not actually mask off the
lower 32 bits as one would expect because 0xffffffff is interpreted as
-1 and then sign-extended to a 64-bit value, i.e. keeping all bits.
The "mov32 %r0, %r0" instruction does correctly mask off the lower 32
bits because it forced the value in %r0 to be a 32-bit value.

test: Fix some ustackdepth tests
Fix these issues.
Issue 1.
In commit e48bf6a23 ("Add support for built-in variable ustackdepth"),
tests ustackdepth2 and ustackdepth_big were introduced and their .r and
.r.p files were links to those of the stackdepth2 test.
In commit 842eabc0e
("test: caller and stackdepth tests for fbt provider"), the stackdepth2
test was explicitly renamed "fbt" since tests for many providers were
being introduced. The links of the earlier patch were not updated.
Issue 2.
The ustackdepth_big test modified perf_event_max_stack. If the test
were interrupted, the value was not restored.
Issue 3.
That ustackdepth_big test only checked that the stackdepth was
consistent with the reported stack. While this check is good, it missed
the point of the test, which is that the system limit could be
increased.

Unify the handling of stack traces in the consumer
Distinguishing between kernel stacks and userspace stacks was done
based on the action id, even when used outside of action context
(i.e. in aggregation keys). That is far from ideal.
Encode the stack type along with the nframes and strsize values in
the data record description argument for stack() and ustack()
records.
The macros for managing that argument are moved to dt_impl.h since
they are internal to the DTrace implementation.
All printing of stack traces is now consolidated in dt_printf.c as
well.

cg: transition [u]stack() from action to subroutine
In order to allow [u]stack() to be used in expressions, they must be
subroutines. An exception is added to allow them to retain their
original behaviour as data recording actions as well.
The implementation change requires a new internal type to be defined
(dt_stack) to hold stack trace data.
This patch does not allow [u]stack() to be used in assignments to
variables just yet, but it supports all previous uses of [u]stack().
Additional functionality will be added on top of this.

options: check *frames option values against system limit
Commit 81e99397d ("Add support for the stack() action") added code to
retrieve the system limit for stack traces and used that value to set
the 'maxframes' option.
However, a user can set the 'maxframes' option from the command line,
which would allow setting the option to value beyond the system limit.
We now record the system limit in dtrace_hdl_t as well as setting the
'maxframes' option to this value as a default. Options processing now
ensures that *frames options cannot be set beyond the system limit.
Note: If 'stackframes', 'ustackframes', or 'jstackframes' are set
before 'maxframes' they could be given a value that exceeds 'maxframes'.
The existing immplementation in the code generator already lowers their
value to 'maxframes' as needed.

Log Message:
-----------
cg, printf: allow storing [u]stack() into vars and printf using %k
To support storing [u]stack() values in variables and as arguments for
printf(), a type definition is introduced:
typedef struct dt_stack {
uint32_t frames;
uint32_t strsz; // optional string blob size
uint32_t is_user // > 0 if userspace stack trace
uint32_t pid; // process id (or 0 for kernel)
uint64_t addrs[n]; // stack trace addresses
} dt_stack_t;
where 'n' is the maximum number of frames that can be retrieved (set
with the 'maxframes' option).
Since dt_stack_t needs to be known early enough to define stack(),
jstack(), and ustack(), it is defined in two stages. First dt_stack_t
is defined as a typedef for struct dt_stack, and once options have been
processed, struct dt_stack is finalized.
Once the value of a stack has been assigned to a variable, it can be
accessed as a regular struct (*not* a pointer to a struct).
Modification is also possible, and safety checks are performed to ensure
that such modifications do not cause crashes in the consumer.

Allow probes not to attach if they were not "needed"
Various kernels prevent the placement of uprobes on particular
instructions -- e.g., on x86 on hlt or multi-byte nops, or on aarch64 on
autiasp. This means, for example, that one cannot place a pid probe on
every possible instruction. If a user explicitly places a probe on a
forbidden instruction, an error message indicates there is a problem.
On the other hand, if the user specifies a wildcard in a pid probe
name, we should skip instructions where no uprobe can be placed.
The problem is that we do not find out an instruction is problematic
until we try to attach, which is long after probe descriptions have been
processed. And when we walk probe descriptions, we do not have
information about which kernels and instructions are problematic.
The motivating problem pertains to pid probes, but we would like
a provider-agnostic solution.
Set an "OPTIONAL" probe flag when a probe is not needed:
* In dt_probe.h, DT_PROBE_FLAG_OPTIONAL is used for the "flags"
member of dt_probe_t.
* For pid-style probes (including USDT and stapsdt), in
include/dtrace/pid.h, DT_PID_PSP_FLAG_OPTIONAL is used for
the pps_flags member of pid_probespec_t.
Remove the old check on "hlt" instructions, since it was not sufficiently
general for other kernels and other problematic instructions.
Existing tests that expose the problem are
test/unittest/pid/tst.coverage.d
test/unittest/pid/tst.emptystack.d
test/unittest/pid/tst.entry_off0.sh
hlt instruction on x86
test/unittest/pid/tst.float.d
multi-byte nop on x86 on newer platforms
test/unittest/pid/tst.entry_off0.sh
autiasp instruction on aarch64 on newer platforms
depending on how the trigger process was built
New tests are added to check that a probe set explicitly on a
problematic instruction will still lead to an error, even if a
probe description before or after it tolerates attach failure.

The problem is that the char array, curpsinfo->pr_fname, could have

Since we do not care about any such garbage bytes, convert to a string.

test: Account for large stack-limit kernel parameter
In commit d0fdeec50 ("test: Fix some ustackdepth tests"), the test was
tweaked to check that the full stack would be recovered if the kernel
stack-limit parameter were increased from a default 127 to greater than
about 190 frames. But this does not work if the system already has
reset the kernel parameter to a high value.
Change the test to deliberately try a "too small" and a "big enough"
value -- again, ultimately restoring the original value.

test: Account again for variations in error messages
In commit 944dac095 ("test: Account for variations in error messages"),
an attempt was made to account for variations in error messages.
However, it was applied to the branch after commit 49e646183
("test: dupstruct: fix extra duplicate identifier case"), and conflict
resolution was not consistent. The earlier patch "standardized"
messages by applying an optional "enumerator" where that label was
missing; the subsequent patch did the opposite. Subsequently, some
logic got messed up.
Fix up the logic. In particular, standardize on the newer error
message (with the "enumerator" label).

Log Message:
-----------
Set lockmem limit before checking BPF helper functions
In dtrace_init(), we set the locked-memory limit, either to the
user-specified value (if any) or to unlimited (by default). We also check
to make sure that certain BPF helper functions are available, falling
over to alternatives or indicating they are not available in case of
problems.
It is possible, however, that the limit is too low when dtrace starts,
causing problems with the helper-function tests before dtrace_init()
even has a chance to reset the limit.
Switch the order to set the limit before checking the helper functions.
A test is added. The underlying problem, however, depends on kernel
version, how locked memory is handled, the behavior of fallback
functions, and so on. So the test could easily pass on some systems
even if the fix is not employed.

test: Clean up stack_fbt test
The idea behind the test is to check the stack() output for some fbt
probe for specific expected frames. An attempt was made to specify the
exact stack that was expected, but there are too many variations among
kernel versions and so maintaining the test was difficult. Loosen the
test to check for only a few expected frames.
The test was also checking that stack()'s first 3 frames matched
stack(3), but such a test is already provided by, for example,
test/unittest/printf/tst.stack.d
test/unittest/stack/tst.stack.d
So, drop the stack(3) stuff.

test: Use /usr/bin/perf for perf
The testsuite package has a dependency on the perf package. But that
package installs perf in /usr/bin. Meanwhile, there is a /sbin/perf,
which is likely to appear earlier in the search path for dtrace users.
That perf is a wrapper for an executable that might not exist, causing
some silent, unexpected behaviors with the test suite.
Change references to "perf" to be explicitly "/usr/bin/perf".

Anchor links (links pointing to specific locations within files) are
broken, at least for viewing the Markdown version of the DTrace User
Guide on github from common browsers, in at least two respects:
*) The arcane ID names are displayed at the anchor sites.
*) The links do not point to the specific locations within the files.
The problem is that the {#ID} syntax is not recognized.
Replace the {#ID} tags with more universal HTML <a id="ID"> tags.
This patch addresses the documentation on built-in variables.

Log Message:
-----------
Bump up the version to 2.0.4
Note that test/unittest/preprocessor/tst.predefined.sh checks that the
__SUNW_D_VERSION preprocessor symbol is consistent with the "dtrace -vV"
message, and both of them simply use the last entry of versions.list and
therefore will be consistent for in-tree builds.
When RPM packages are built from the .spec file, however, _DT_VERSION,
used for the "dtrace -vV" "This is" message, comes from the .spec file.
Append a 2.0.4 entry to versions.list.
Remove the VERSION=%{version} from dtrace.spec build's make line, so
that the version of the implementation is defined by the source code
itself. The version in the spec file should be only the version of the
packaging.
