  safer cleanup when failing to compile regexps

Prior to this commit when producing a warning the regexp compiler
would check if the warning category was marked as FATAL, and if it was
it would add clean up to the save stack to release buffers used during
compilation and to release the working REGEXP SV.

This causes two type of problems:

- if an error was already queued, Perl_ck_warner() returns even if
  the warning is fatal, this meant that the normal clean up code
  Perl_re_op_compile() would also run, resulting in a double free
  of the buffers.

- without fatal warnings, if a $SIG{__WARN__} handler died, the
  buffers and the working REGEXP SV would leak.

Avoid this by using SAVEDESTRUCTOR_X() to release the memory and
optionally the SV at the end of scope.

Fixes #21661

Adding _GNU_SOURCE, which was done much later, should give us the
GNU-ish symbols (though POSIX_C_SOURCE would be more general.)

I couldn't find the reason for this being added, but the C++
headers react badly to it:

  porting/cpphdrcheck.t: test perl's headers with C++ compilers

This searches for a C++ compiler based on the supplied C compiler, and
checks that compiler for any options controlling the C++ standard
requested, including simple checks that the compiler supports that
standard.

If a C++ compiler is found, test compilation of the same simple code
as above but with the perl headers included after any C++ headers.

Ideally we'd also test runtime, but would require more complex test
code, which I leave to later contributors (which may still be me).

Tested at various times with:

 - MSVC
 - gcc
 - clang
 - Oracle/Sun Development Workshop cc (CC is the C++ compiler), on
   Oracle Linux
 - Intel oneAPI compiler (llvm based apparently, and now free to use)
 - Intel classic compiler (discontinued)

Currently this probes the compiler for C++ sanity with the perl
ccflags, since icc (Intel classic) would successfully build the sample
without perl's ccflags, but then fail with both the headers and perl's
ccflags.  It turned out to fail with just the ccflags, and since the
primary intent is to test the headers, I probe *with* ccflags.

The Sun Workshop compiler failed to build the C++11 or 14 sample at
all in my testing, which may have been due to an installation problem.

Jan requested a minor change to that PR which wasn't followed up on, so

includes that requested change in August 2023.

This still hasn't been acted on.

  isnan (long double): always use the C99 version

C99 requires that isnan() is a generic macro that accepts the
standard floating point types (float, double, long double).

We always include math.h eventually, so this macro should be
available.

This is complicated by C++.  C++98 depends on C89, which does
not require isnan(), but since we do require C99, I think we
need to require a minimum of C++11, which follows C99.

C++11 does *not* define isnan() as a macro, but as a set of
overloaded functions, which produces almost the same result,
the difference being that the macro test that was done by this
code is no longer valid.

The old code would fail to build with C++ long double builds
with gcc on Window:

  class.c: store the stash in the constructor CV stash slot

This code previously stored the stash for the class in the CV's
any_cv slot, and marked that to be released when the CV is released.

But it does not bump the reference count of the stash that I can
see.

When I tried releasing the constructor SV while working on #22169
I found perl would crash, incrementing the stash reference count
prevents that, but leaves us with a reference loop.

But it turns out that CVs already have a slot to store their stash in
and an API that correctly handles reference counting for that slot.

So use CvSTASH_set()/CvSTASH() to manage the stash for "$class::new"
methods.

  my_strnlen(): eliminate unneeded casting away of const

Noticed this while reviewing #22271.

If you build with:

  ./Configure -des -Dusedevel -Ud_strnlen -Accflags=-Wcast-qual -Dcc=g++

you will see amongst many other warnings:

inline.h: In function ‘size_t Perl_my_strnlen(const char*, size_t)’:
inline.h:4220:23: warning: cast from type ‘const void*’ to type ‘char*’ casts 
away qualifiers [-Wcast-qual]
 4220 | const char *end = (char *) memchr(str, '\0', maxlen);
  |   ^~

The cast itself is only needed on C++ to cast from "const void *", C
doesn't require any cast here.

C99 requires that isnan() is a generic macro that accepts the
standard floating point types (float, double, long double).

We always include math.h eventually, so this macro should be
available.

This is complicated by C++.  C++98 depends on C89, which does
not require isnan(), but since we do require C99, I think we
need to require a minimum of C++11, which follows C99.

C++11 does *not* define isnan() as a macro, but as a set of
overloaded functions, which produces almost the same result,
the difference being that the macro test that was done by this
code is no longer valid.

The old code would fail to build with long double builds C++
builds with gcc on Window:

  porting/cpphdrcheck.t: test perl's headers with C++ compilers

This searches for a C++ compiler based on the supplied C compiler, and
checks that compiler for any options controlling the C++ standard
requested, including simple checks that the compiler supports that
standard.

If a C++ compiler is found, test compilation of the same simple code
as above but with the perl headers included after any C++ headers.

Ideally we'd also test runtime, but would require more complex test
code, which I leave to later contributors (which may still be me).

Tested at various times with:

 - MSVC
 - gcc
 - clang
 - Oracle/Sun Development Workshop cc (CC is the C++ compiler), on
   Oracle Linux
 - Intel oneAPI compiler (llvm based apparently, and now free to use)
 - Intel classic compiler (discontinued)

Currently this probes the compiler for C++ sanity with the perl
ccflags, since icc (Intel classic) would successfully build the sample
without perl's ccflags, but then fail with both the headers and perl's
ccflags.  It turned out to fail with just the ccflags, and since the
primary intent is to test the headers, I probe *with* ccflags.

The Sun Workshop compiler failed to build the C++11 or 14 sample at
all in my testing, which may have been due to an installation problem.

  perly LSTOPSUB: prevent a double op free between parse stack and CV

The reeproducer resulted in the "block" OP being both on the parser
stack and attacked to the CV.  If an error occurred while parsing the
rest of the list operator clean up would release the OP as attached
to the CV, and the same OP on the parse stack, resulting in a double
free.

It's unclear to me whether bison is intended to support modifying
the parse stack entry like this, but it appears to work here.

Fixes #21724

This occurs with clang-17, and possibly other versions:

[-Wunused-but-set-variable]
  667 | U32 wordlen  = 0; /* required init */
  | ^

This happens because while the first loop in Perl_make_trie calculates
wordlen, mostly via the TRIE_READ_CHAR macro, that calculated value
isn't used.

The later loops do use the value of wordlen via the TRIE_HANDLE_WORD()
macro.

Unfortunately the use in TRIE_READ_CHAR() means we can't remove
this first definition, so suppress the warning.

This does appear to be spurious, the gcc documentation claims not
to check array bounds on trailing 1 element arrays for backward
compatibility.

This warning would be reasonable if the hek itself was allocated on
the stack, part of an array of HEKs, or embedded in another struct,
but HvNAME_HEK() returns a pointer to a HEK, for which gcc has no
knowledge of the source.

This warning only appears in debugging builds, but the only
difference from non-debugging builds is the HEKfARG() within the
DEBUG_o(), which is a simple cast to (void *), which I don't see
having an effect on whether the compiler considers HEK itself as
part of a structure, or of unknown origin.

So I expect it's just a gcc bug, and there are know issues with this
warning.

  toggle_locale_i: eliminate NULL for %s format warning

The C99 printf() family of functions do not permit a NULL
pointer for the %s format specifier.

In this case, there's a NULL check done immediately afterwards,
allowing the compiler to detect that locale_to_restore_to could
be NULL.

While PerlIO_printf() (via sv_vcatpvfn_flags()) does allow NULL,
it isn't permitted by the standard implementation, so gcc warns.

Ideally the compiler would provide customisation hooks for this
warning, but it doesn't, and since the -Wformat family of
warnings are useful, do the minimal change to prevent it in
this case.

This allows a debugging perl to be built with the high water mark
checks disabled, or a non-debugging perl to be built with the
high water marks enabled.

This should allow Debian, the reporter for #16607 to build both their
normal perl and debugperl with the same state of high water mark
checks and avoid the mismatch between a debugperl and non-debug
dynamic extension.

Fixes #16607

  win32.c: suppress -Wcast-function-type warnings

This appears to be the only place these warnings are produced even
though win32/win32.c contains several other function type casts.

None of the non-warning casts use the "void (*)(void)" type that is
documented to suppress the warning, and adding such a cast to
the lines warning seems less safe to me, cast from a stdcall
function pointer to a cdecl function pointer and back.

So, just suppress the warning where I saw it.

The LC_ALL syntax detection wrote some of what it detected to

On Linux this was:

  prepare_export_lexical: save PL_comppad safely

When the pad being saved and the pad for PL_compcv is the same,
in some cases the actual exports would result in reallocating the
AvARRAY() for the saved PL_comppad.

The LEAVE in finish_export_lexical() would restore the old PL_comppad
(which is fine) and the pre-reallocation PL_curpad (which isn't fine).

This would later panic.

SAVECOMPPAD; restores PL_comppad on LEAVE and then restores PL_curpad
from PL_comppad, preventing the desync between those values.

It's unclear to me why only the save_BEGINs; causes this, but the fix
does fix a real problem and prevents the panics that I'm aware of
here.

Fixes #21981

Apparently a recent Ubuntu update changed the ASLR entropy to
use more bits which is incompatible with ASAN as shipped with
Ubuntu.

This adjusts the entropy bits to be compatible with ASAN.

  DynaLoader: dl_dyld.xs: don't undef bool

I expect this was added when we added our own bool, and before
we used bool so liberally ourselves.  Now dl_dyld.xs fails to
compile, since MY_CXT_CLONE indirectly uses UNLIKELY() which
casts to bool.

Tested locally with:

  ./Configure -des -Dusedevel -Dusethreads -Ddlsrc=dl_dyld.xs

on a modern Darwin, which failed before this change and builds
after.

Based on work done by Sevan Janiyan in #21751.

Fixes #21751

  safer cleanup when failing to compile regexps

Prior to this commit when producing a warning the regexp compiler
would check if the warning category was marked as FATAL, and if it was
it would add clean up to the save stack to release buffers used during
compilation and to release the working REGEXP SV.

This causes two type of problems:

- if an error was already queued, Perl_ck_warner() returns even if
  the warning is fatal, this meant that the normal clean up code
  Perl_re_op_compile() would also run, resulting in a double free
  of the buffers.

- without fatal warnings, if a $SIG{__WARN__} handler died, the
  buffers and the working REGEXP SV would leak.

Avoid this by using SAVEDESTRUCTOR_X() to release the memory and
optionally the SV at the end of scope.

Fixes #21661

  no bareword_filehandes: don't look up class barewords as handles

This prevents SomeBareword from being looked up as a filehandle:

  no feature "bareword_filehandles";
  SomeBareword->method();

Since "bareword_filehandles" is explicitly about bareword handles,
it does not prevent other string to object/class look ups from
resolving the class as a filehandle, eg for the following:

  "SomeLiteral"->method();
  my $x = "SomeVariable";
  $x->method();

both are looked up as file handles per normal.

Note that in any of these cases, with or without the
bareword_filehandles feature, if the name is a bareword that
has been resolved as a class name since the last time the
stash cache was cleared, it will be resolved as a class name,
not a filehandle.

leaving it possible for it to be NULL after the switch.

Of course the values of "context" for that are invalid, so throw
an error.  This should also resolve this for Coverity and perhaps
other static analysis.

which turned out to be wrong, so make them Stack_off_t.

This allows XS::Framework or similar code to build with a default
build of perl, but it will still fail to build if perl is built
with -DPERL_STACK_OFFSET_SSIZET, which can only be fixed by updating
XS::Framework to use Stack_off_t itself.

Fixes #21782

The changes to t/test.pl appear to be real bugs.

This allows `make test_harness` to run, but many tests will still
fail under -Dusedefaultstrict

This addresses #21732 but does not fix it.  I'm unsure how
supported that build option is.

  allow "used only once" warnings to be fatal

"used only once" warnings are special, instead of being emitted at
the code where the name in question is used, they are emitted during
a scan of the symbol table done after parsing has finished.

This meant that any FATAL flags set in the COP for the parse point of
the name is no longer in scope, so the warnings we emit can't be
treated as fatal.

To make them behave as FATAL set a new flag on the name if fatal
WARN_ONCE warnings are enabled and use that to dispatch the warnings
as normal or fatally when we do the symbol table scan.

I originally approached the dispatch as fatal or non-fatal by messing
around with cop_warnings, but that was dumb, and I went for a much
simpler change.

The same applies doubly to release tarballs.

So skip this test for maint/version numbers.

Keep the test for devel releases, since they have limited support

  safer cleanup when failing to compile regexps

Prior to this commit when producing a warning the regexp compiler
would check if the warning category was marked as FATAL, and if it was
it would add clean up to the save stack to release buffers used during
compilation and to release the working REGEXP SV.

This causes two type of problems:

- if an error was already queued, Perl_ck_warner() returns even if
  the warning is fatal, this meant that the normal clean up code
  Perl_re_op_compile() would also run, resulting in a double free
  of the buffers.

- without fatal warnings, if a $SIG{__WARN__} handler died, the
  buffers and the working REGEXP SV would leak.

Avoid this by using SAVEDESTRUCTOR_X() to release the memory and
optionally the SV at the end of scope.

  Fix read/write past buffer end: perl-security#140

A package name may be specified in a \p{...} regular expression
construct.  If unspecified, "utf8::" is assumed, which is the package
all official Unicode properties are in.  By specifying a different
package, one can create a user-defined property with the same
unqualified name as a Unicode one.  Such a property is defined by a sub
whose name begins with "Is" or "In", and if the sub wishes to refer to
an official Unicode property, it must explicitly specify the "utf8::".
S_parse_uniprop_string() is used to parse the interior of both \p{} and
the user-defined sub lines.

In S_parse_uniprop_string(), it parses the input "name" parameter,
creating a modified copy, "lookup_name", malloc'ed with the same size as
"name".  The modifications are essentially to create a canonicalized
version of the input, with such things as extraneous white-space
stripped off.  I found it convenient to strip off the package specifier
"utf8::".  To to so, the code simply pretends "lookup_name" begins just
after the "utf8::", and adjusts various other values to compensate.
However, it missed the adjustment of one required one.

This is only a problem when the property name begins with "perl" and
isn't "perlspace" nor "perlword".  All such ones are undocumented
internal properties.

What happens in this case is that the input is reparsed with slightly
different rules in effect as to what is legal versus illegal.  The
problem is that "lookup_name" no longer is pointing to its initial
value, but "name" is.  Thus the space allocated for filling "lookup_name"
is now shorter than "name", and as this shortened "lookup_name" is
filled by copying suitable portions of "name", the write can be to
unallocated space.

The solution is to skip the "utf8::" when reparsing "name".  Then both
"lookup_name" and "name" are effectively shortened by the same amount,
and there is no going off the end.

This commit also does white-space adjustment so that things align
vertically for readability.

This can be easily backported to earlier Perl releases.

  win32: default the shell to cmd.exe in the Windows system directory

This prevents picking up cmd.exe from the current directory, or
even from the PATH.

This protects against a privilege escalation attack where an attacker
in a separate session creates a cmd.exe in a directory where the
target account happens to have its current directory.

  globvar.t: use nm -P for portability

POSIX specifies well defined output for nm -P

This will hopefully run this test on more platforms, including old AIX,
for which nm produces a different output from what the test expected.

Part of #21623

  Log Message:

  globvar.t: allow duplicate definitions of symbols

nm on AIX can list both local and global definitions for the same
variable, which meant the parsing would delete the first instance
from %exported, but then add the second to %unexported, failing the
test.

This didn't fail on AIX 5 because the default nm output didn't
match what the code expected when checking for PL_Yes, and so
the entire test script skipped.

Fixes #21623
