The IETFAtrrSyntax type is used for the values of several attributes
defined in RFC 5755 for use with attribute certificates.
Specifically this type is used with the "Charging Identity" and
"Group" attributes.

Add functions to print an attribute certificate. Several
attribute value types defined by the RFC 5755 specification
are multi-field values (i.e ASN1_SEQUENCE rather than an ASN1_STRING
or similar format). Currently those values are printed using
`ASN1_item_print`. A more user-friendly output mechanism (maybe
similar to the i2r_ functions used for X509 extensions) could be
added in future.

Add support for attribute certificates (v2) as described
in RFC 5755 profile.
Attribute certificates provide a mechanism to manage authorization
information separately from the identity information provided by
public key certificates.
This initial patch adds the ASN.1 definitions
and I/O API. Accessor functions for the certificate fields
will be added in subsequent patches.

Create a new hashtable that is more efficient than the existing LHASH_OF
implementation. the new ossl_ht api offers several new features that
improve performance opportunistically
* A more generalized hash function. Currently using fnv1a, provides a
more general hash function, but can still be overridden where needed
* Improved locking and reference counting. This hash table is
internally locked with an RCU lock, and optionally reference counts
elements, allowing for users to not have to create and manage their
own read/write locks
* Lockless operation. The hash table can be configured to operate
locklessly on the read side, improving performance, at the sacrifice
of the ability to grow the hash table or delete elements from it
* A filter function allowing for the retrieval of several elements at a
time matching a given criteria without having to hold a lock
permanently
* a doall_until iterator variant, that allows callers which need to
iterate over the entire hash table until a given condition is met (as
defined by the return value of the iterator callback). This allows
for callers attempting to do expensive cache searches for a small
number of elements to terminate the iteration early, saving cpu cycles
* Dynamic type safety. The hash table provides operations to set and
get data of a specific type without having to define a type at the
instatiation point
* Multiple data type storage. The hash table can store multiple data
types allowing for more flexible usage
* Ubsan safety. Because the API deals with concrete single types
(HT_KEY and HT_VALUE), leaving specific type casting to the call
recipient with dynamic type validation, this implementation is safe
from the ubsan undefined behavior warnings that require additional
thunking on callbacks.
Testing of this new hashtable with an equivalent hash function, I can
observe approximately a 6% performance improvement in the lhash_test

Generally we can get away with just using CRYPTO_atomic_load to do
stores by reversing the source and target variables, but doing so
creates a problem for the thread sanitizer as CRYPTO_atomic_load hard
codes an __ATOMIC_ACQUIRE constraint, which confuses tsan into thinking
that loads and stores aren't properly ordered, leading to RAW/WAR
hazzards getting reported. Instead create a CRYPTO_atomic_store api
that is identical to the load variant, save for the fact that the value
is a unit64_t rather than a pointer that gets stored using an
__ATOMIC_RELEASE constraint, satisfying tsan.

This is unfortunate, but seems necessecary
tsan in gcc/clang tracks data races by recording memory references made
while various locks are held. If it finds that a given address is
read/written while under lock (or under no locks without the use of
atomics), it issues a warning
this creates a specific problem for rcu, because on the write side of a
critical section, we write data under the protection of a lock, but by
definition the read side has no lock, and so rcu warns us about it,
which is really a false positive, because we know that, even if a
pointer changes its value, the data it points to will be valid.
The best way to fix it, short of implementing tsan hooks for rcu locks
in any thread sanitizer in the field, is to 'fake it'. If thread
sanitization is activated, then in ossl_rcu_write_[lock|unlock] we add
annotations to make the sanitizer think that, after the write lock is
taken, that we immediately unlock it, and lock it right before we unlock
it again. In this way tsan thinks there are no locks held while
referencing protected data on the read or write side.
we still need to use atomics to ensure that tsan recognizes that we are
doing atomic accesses safely, but thats ok, and we still get warnings if
we don't do that properly

Currently, rcu has a global bit of data, the CRYPTO_THREAD_LOCAL object
to store per thread data. This works in some cases, but fails in FIPS,
becuase it contains its own copy of the global key.
So
1) Make the rcu_thr_key a per-context variable, and force
ossl_rcu_lock_new to be context aware
2) Store a pointer to the context in the lock object
3) Use the context to get the global thread key on read/write lock
4) Use ossl_thread_start_init to properly register a cleanup on thread
exit
5) Fix up missed calls to OSSL_thread_stop() in our tests

current `translate_msg()` function attempts to set `->msg_name`
(and `->msg_namelen`) with `BIO`'s peer name (connection destination)
regardless if underlying socket is connected or not. Such implementation
uncovers differences in socket implementation between various OSes.
As we have learned hard way `sendmsg()` and `sendmmsg()` on `OpenBSD`
and (`MacOS` too) fail to send messages with `->msg_name` being
set on connected socket. In such case the caller receives
`EISCON` errro.
I think `translate_msg()` caller should provide a hint to indicate
whether we deal with connected (or un-connected) socket. For
connected sockets the peer's name should not be set/filled
by `translate_msg()`. On the other hand if socket is un-connected,
then `translate_msg()` must populate `->msg_name` and `->msg_namelen`
members.
The caller can use `getpeername(2)` to see if socket is
connected. If `getpeername()` succeeds then we must be dealing
with connected socket and `translate_msg()` must not set
`->msg_name` and `->msg_namelen` members. If `getpeername(2)`
fails, then `translate_msg()` must provide peer's name (destination
address) in `->msg_name` and set `->msg_namelen` accordingly.
The propposed fix introduces `is_connected()` function,
which applies `getpeername()` to socket bound to `BIO` instance.
The `dgram_sendmmsg()` uses `is_connected()` as a hint
for `translate_msg()` function, so msghdr gets initialized
with respect to socket state.
The change also modifies existing `test/quic_client_test.c`
so it also covers the case of connected socket. To keep
things simple we can introduce optional argument `connect_first`
to `./quic_client_test` function. Without `connect_first`
the test run as usual. With `connect_first` the test creates
and connects socket first. Then it passes such socket to
`BIO` sub-system to perform `QUIC` connect test as usual.

The atomics fallbacks were using 'void *' as a generic transport for all
possible scalar and pointer types, with the hypothesis that a pointer is
as large as the largest possible scalar type that we would use.
Then enters the use of uint64_t, which is larger than a pointer on any
32-bit system (or any system that has 32-bit pointer configurations).
We could of course choose a larger type as a generic transport. However,
that only pushes the problem forward in time... and it's still a hack.
It's therefore safer to reimplement the fallbacks per type that atomics
are used for, and deal with missing per type fallbacks when the need
arrises in the future.
For test build purposes, the macro USE_ATOMIC_FALLBACKS is introduced.
If OpenSSL is configured with '-DUSE_ATOMIC_FALLBACKS', the fallbacks
will be used, unconditionally.

CRYPTO_atomic_add has a lock as a parameter, which is often ignored, but in
some cases (for example, when BROKEN_CLANG_ATOMICS is defined) it is required.
There is no easy way to determine if the lock is needed or not. The current
logic looks like this:
if defined(OPENSSL_THREADS) && !defined(CRYPTO_TDEBUG) && !defined(OPENSSL_SYS_WINDOWS)
if defined(__GNUC__) && defined(__ATOMIC_ACQ_REL) && !defined(BROKEN_CLANG_ATOMICS)
- It works without the lock, but in general the need for the
lock depends on __atomic_is_lock_free results
elif defined(__sun) && (defined(__SunOS_5_10) || defined(__SunOS_5_11))
- The lock is not needed (unless ret is NULL, which should never
happen?)
else
- The lock is required
endif
else
- The lock is not needed
endif
Adding such conditions outside of crypto.h is error-prone, so it is better to
always allocate the lock, otherwise CRYPTO_atomic_add may silently fail.
Fixes #23376.

Since the addition of macos14 M1 runners in our CI jobs we've been
seeing periodic random failures in the test_threads CI job.
Specifically we've seen instances in which the shared pointer in the
test (which points to a monotonically incrementing uint64_t went
backwards.
From taking a look at the disassembled code in the failing case, we see
that __atomic_load_n when emitted in clang 15 looks like this
0000000100120488 <_ossl_rcu_uptr_deref>:
100120488: f8bfc000 ldapr x0, [x0]
10012048c: d65f03c0 ret
Notably, when compiling with gcc on the same system we get this output
instead:
0000000100120488 <_ossl_rcu_uptr_deref>:
100120488: f8bfc000 ldar x0, [x0]
10012048c: d65f03c0 ret
Checking the arm docs for the difference between ldar and ldapr:
https://developer.arm.com/documentation/ddi0602/2023-09/Base-Instructions/LDAPR--Load-Acquire-RCpc-Register-
https://developer.arm.com/documentation/dui0802/b/A64-Data-Transfer-Instructions/LDAR
It seems that the ldar instruction provides a global cpu fence, not
completing until all writes in a given cpus writeback queue have
completed
Conversely, the ldapr instruction attmpts to achieve performance
improvements by honoring the Local Ordering register available in the
system coprocessor, only flushing writes in the same address region as
other cpus on the system.
I believe that on M1 virtualized cpus the ldapr is not properly ordering
writes, leading to an out of order read, despite the needed fencing.
I've opened an issue with apple on this here:
https://developer.apple.com/forums/thread/749530
I believe that it is not safe to issue an ldapr instruction unless the
programmer knows that the Local order registers are properly configured
for use on the system.
So to fix it I'm proposing with this patch that we, in the event that:
1) __APPLE__ is defined
AND
2) __clang__ is defined
AND
3) __aarch64__ is defined
during the build, that we override the ATOMIC_LOAD_N macro in the rcu
code such that it uses a custom function with inline assembly to emit
the ldar instruction rather than the ldapr instruction. The above
conditions should get us to where this is only used on more recent MAC
cpus, and only in the case where the affected clang compiler emits the
offending instruction.
I've run this patch 10 times in our CI and failed to reproduce the
issue, whereas previously I could trigger it within 5 runs routinely.

cast them to size_t to avoid the integer overflow.

GCC 13.1.0 were reporting a compilation warning with -O2/3 and
-Waggressive-loop-optimizations. GCC is raising an undefined behavior in the
while loop. Replace the while loop with a memset call at the top of the
function.
Fixes #21088
