There are two depth limiting parameters for XSLT templates.
1) maxTemplateDepth
This corresponds to the recursion depth of a template. For very
complicated templates this can be hit.
2) maxTemplateVars
This is the total number of live variables. When using recursive
templates with lots of parameters you can hit this limit.
This patch introduces two new properties to XSLTProcessor that
corresponds to the above variables.
MAPPHAR_FAIL will call the destructor of the manifest, mounted_dirs, and
virtual_dirs tables. When a new phar object is allocated using (p)ecalloc,
the bytes are zeroed, but the flag for an uninitialized table is
non-zero. So we have to manually set the flag in case that we have a
code path that can destroy the tables without first initializing them at
least once.

If the destination already exists, then the `add` function on the
manifest will return NULL, resulting in a NULL entry and therefore a
NULL deref. As `copy()` (not `Phar::copy`) chooses to succeed and
overwrite the destination if it already exists, we should do the same.
Therefore the fix is as simple as changing `add` to `update`.
Closes GH-13840.
This fixes the issue with unbounded waiting on SSL_peek which can happen
when only part of the record is fetched. It makes socket non blocking so
it is possible to verify if OpenSSL is expecting some more data or if
there is an error.
This also fixes bug #79501
Closes GH-13487
Useful to control how many SYN packets the client will send to the
server before giving up establishing a connection if the server does
not respond (usually 5 or 6 by default).

This regressed in 9a250cc9d6, which allowed static properties to get
overridden by a trait during inheritance. In particular, because of the
change to the loop in zend_update_parent_ce(), it's not guaranteed that
all indirects are after one another.
This means that during persisting the zvals of the static members table,
some static properties may be skipped. In case of the test code, this
means that the array in the trait will keep referring to the old, new
freed, stale value. To solve this, we check the type for IS_INDIRECT,
which is the same as what zend_persist_calc() is already doing anyway.
Since 2543e61aed we can check for IS_INDIRECT to see if it should be
persisted or not.
Closes GH-13794.
Bumps the minimum required OpenSSL version from 1.0.2 to 1.1.1.
OpenSSL 1.1.1 is an LTS release, but has reached[^1] EOL from upstream. However, Linux distro/OS vendors
continue to ship OpenSSL 1.1.1, so 1.1.1 was picked as the minimum. The current minimum 1.0.2 reached
EOL in 2018.
Bumping the minimum required OpenSSL version makes it possible for ext-openssl to remove a bunch of
conditional code, and assume that TLS 1.3 (shipped with OpenSSL 1.1.1) will be supported everywhere.
- Debian buster: 1.1.1[^2]
- Ubuntu 20.04: 1.1.1[^3]
- CentOS/RHEL 7: 1.0.2
- RHEL 8/Rocky 8/EL 8: 1.1.1
- Fedora 38: 3.0.9 (`openssl11` provides OpenSSL 1.1 as well)
RHEL/CentOS 7 reaches EOL mid 2024, so for PHP 8.4 scheduled towards the end of this year, we can safely
bump the minimum OpenSSL version.

Symfony relies on finding the exception handler in the handler stack. There's
currently no clean API to find it, so they pop all the handlers, and push them
again once the stack is empty. This PR attempts to minimize the BC break by
pushing the current handler onto the stack and clearing the current handler, and
restoring it once it has finished. This is essentially equivalent to
set_exception_handler(null) and restore_exception_handler().
restore_exception_handler() however is only called if the exception handler is
still unset. If the handler has pushed a new handler in the meantime, we assume
it knows what it's doing.

Inherited methods regardless of source must share the original runtime cache. Traits were missed.
This adds ZEND_ACC_TRAIT_CLONE to internal functions as well to allow easy distinction of these.
In commit 85e5635a, a feature test for the various libgd image formats
was added. That test however erroneously omits the GDLIB_CFLAGS (from
pkg-config) during compilation. This can lead to build failures and
therefore false negatives from the test.
Here, we add $GDLIB_CFLAGS to $CFLAGS for the duration of the test.

Regressed in 6fbf81c.
There is a missing error check on spl_filesystem_file_read_line(), which
means that if the line could not be read (e.g. because we're at the end
of the file), it will not set intern->u.file.current_line, which will
cause a NULL pointer deref later on.
Fix it by adding a check, and reintroducing the silent flag partially to
be able to throw an exception like it did in the past.
Closes GH-13692.
This is not just an issue due to missing initialization since moving the state
struct directly into the module globals. In earlier versions changing the mode
to `MT_RAND_PHP` within a single request would also affect the mode for
subsequent requests.
Original commit message follows:
This is a follow-up fix for GH-13579. The issue was detected in the nightly
MSAN build.

This was tested on OpenBSD sparc64 and all fiber related tests pass.
On OpenBSD stackghost prevents the modification of the return address
and therefor an extra trampoline is needed in make_fcontext(). This
should not matter on other OS implementing sysv ABI and the trampoline
should work there as well.

Inside `zend_object_std_dtor` the weakrefs are notified after the destruction
of properties already took place. In this test case, the destructor of an anon
class will be invoked due to the property destruction. That class has a
weak reference to its parent. This means that the destructor can access
parent properties that already have been destroyed, resulting in a UAF.
Fix this by notifying the weakrefs at the start of the object's
destruction.
Closes GH-13613.
the man page states `the locale facet is determined by the category argument, which should be
one of the LC_xxx constants defined in the <locale.h> header, excluding LC_ALL`,
since the 0.22.5 release, sanity checks had been strenghtened leading to
an abort with the Zend/tests/arginfo_zpp_mismatch.phpt test setting the
category to 0 which is LC_ALL on macOs.

The character set ID included in the handshake data at the time of connection
actually only includes the lower 8 bits of the ID, so if try to use this to specify
a character set, the corresponding character set may not exist.
In case of an invalid character set, the default character set is now used
without an error.

There's a test that tries to make /etc world-writable, and asserts that
it fails. Although this test is guarded by a root user check, there are
situations where you don't need to be root to be able to do this.
This may thus have unwanted effects on your live filesystem.
The simple solution is to remove that part of the test. It doesn't
really add value anyway: we're trying to test the chmod error path, but
that exact same error path can be reached with any failure condition
that the kernel gives. For example, trying to chmod a non-existent file
will trigger the same code path.
While at it, also prefix the test path for the non-existent file such
that we don't accidentally modify the filesystem.
The chroot now has a better root-user check, that will not modify the
filesystem.
Other root-modifying mkdir tests were removed because they added no
value either.
Closes GH-13566.
PHP 8.1 and below interpreted unknown modes as `MT_RAND_MT19937`, but PHP 8.2+
interprets them as `MT_RAND_PHP`.
Align the behavior with PHP 8.1 and below, because folks should be steered
towards the standard mode.
When unserializing, the cached_resize field was not reset to -1
correctly, causing the setSize() method to think we were inside of a
resize operation.
Closes GH-13543.
