Limit job count on compiler zoo builds
The security repo keeps failing our compiler zoo jobs, consistently. It
appears to be happening because our compiler zoo jobs use make -j
without any limit on the number of jobs, leading to github aborting them
all when the workload gets too high. I suspect that we're using a
smaller runner in the security repo than we are in our public repo,
which is why we don't see it there.
Our other CI jobs all limit the job count to 4 during make, do the same
here.

TPM 1.2 Endorsement Key certificates use id-RSAES-OAEP
(NID_rsaesOaep) as their SubjectPublicKeyInfo algorithm
identifier per TCG Credential Profiles V1.2 section 3.2.7.
The underlying key is a standard RSAPublicKey. Without
this mapping, X509_get_pubkey() fails with a decode error
and X509_verify_cert() cannot validate these certificates.
Add NID_rsaesOaep handling to the three SPKI decode paths,
each of which points at the other two so future changes stay
in sync:
- x509_pubkey_decode(): remap the NID to NID_rsaEncryption
for the legacy ameth lookup. This path is reached via
d2i_RSA_PUBKEY()/ossl_d2i_PUBKEY_legacy(), which is in
turn invoked by the provider RSA decoder's rsa_d2i_PUBKEY,
so it is load-bearing even when the provider path is in
use.
- x509_pubkey_ex_d2i_ex(): use "RSA" as the decoder keytype
name so OSSL_DECODER_CTX_new_for_pkey() selects the RSA
provider decoder. The NID check precedes OBJ_obj2txt()
so the text conversion is skipped when unused.
- ossl_spki2typespki_der_decode(): same remap in the
SPKI-to-type-SPKI provider decoder chain. Flatten the
existing SM2 special case while here: the original code
relied on a dangling else across the #endif, which made
the rsaesOaep branch awkward to add. The new structure
initializes dataname to empty, applies each special case
in turn, and falls back to OBJ_obj2txt() only when no
override applied. strcpy() is replaced with
OPENSSL_strlcpy() for consistency with surrounding code.
The OAEP AlgorithmIdentifier parameters (which carry a
TCG-specific pSourceAlgorithm "TCPA" for TPM EKs) are
deliberately not interpreted; only the RSAPublicKey body is
consumed.
Add a test using a real TPM 1.2 EK certificate. The test
exercises both the provider decoder path (via X509_from_strings
+ X509_get0_pubkey) and, when deprecated APIs are available,
the legacy path (via d2i_RSA_PUBKEY), confirming the key
decodes to an RSA EVP_PKEY of the expected size.

ssl/quic/quic_port.c: fix leak in port_make_channel()
Free pre-existing ch->qlog_title before OPENSSL_strdup to avoid
leaking the value allocated in ossl_quic_channel_alloc(). Use
ossl_quic_channel_free() on strdup failure to ensure proper cleanup.
On s390x, the distribution of the query cache hash values is different
compared to other architectures, probably because of endianess and pointer
alignment being different (the hash key contains pointer values and integers).
This leads to the fact that ossl_ht_cache_QUERY_insert() is not always able to
add a query during the FIPS selftests, and thus ossl_ht_cache_QUERY_insert()
returns -1 is such cases.
Increase the number of retries inside ossl_ht_insert() to at least the
number elements per neighborhood plus 1. With this it is able to grow the
hash table enough so that the queries used during the FIPS selftest can
all be added to the hash table, even on s390x.
There is still no guarantee that the number of retries is enough for all
possible queries. It can still happen that certain queries can't be added to
the cache, even on other architectures. This does not really hurt, such
queries will just not be cached and are freshly fetched again the next time.

Handle NULL-buffer size probe in ossl_param_build_set_bn_pad()
ossl_param_build_set_bn_pad() is reached by two distinct caller
populations. When an OSSL_PARAM_BLD template is supplied
(bld != NULL), the template allocates backing storage internally and
no caller-side sizing is required. When an explicit OSSL_PARAM[]
array is supplied (bld == NULL), the caller follows the standard
OSSL_PARAM size-probe contract: invoke the primitive once with
p->data == NULL to learn the required size via p->return_size, then
allocate a buffer of that size and invoke again with the real
storage.
The bld == NULL branch did not honour the size-probe contract: with
p->data == NULL and a non-zero sz it fell through to
OSSL_PARAM_set_BN() and raised CRYPTO_R_TOO_SMALL_BUFFER, so callers
could never discover the required size.
The defect has been latent across several releases. This primitive
is the *padded* BN setter: it emits a fixed-width encoding regardless
of the BN's actual magnitude, which is needed for the private key --
a minimal encoding would leak its bit-length through timing or
allocation side channels. In practice the private key is the only
provider parameter that reaches this primitive. Callers that want
private-key material have historically done so through
EVP_PKEY_todata() and its OSSL_PARAM_BLD template path, where the
bug is invisible. EVP_PKEY_get_params() callers exist but have not
previously needed the private-key BN. Any caller that does request
it on the explicit-params path -- whether by name or as part of
iterating a provider's full gettable list -- now sees the probe
behave as it does elsewhere.

Use EVP_MD_fetch() instead of EVP_get_digestbynid() in X509/TLS paths
EVP_get_digestbynid() only searches the legacy built-in digest table and
cannot resolve provider-only digests, which breaks X509 signature info
computation, GOST TLS handshakes, and OCSP cert ID matching when the
digest is loaded exclusively through a provider. Switch the three affected
sites to use EVP_MD_fetch() (with the appropriate libctx/propq).
x509_sig_info_init() gains libctx/propq parameters propagated
from the X509 struct by its caller.
AIX header files don't properly expose sendmmsg/recvmmsg function
declarations. Disable these functions to avoid implicit declaration
errors with clang 16+.
This issue was discovered when building Node.js with clang.

This patch adds an AArch64-specific extension cross-compile workflow.
This is inspired by the existing RISC-V extension cross-compile

Specifically they have observed the following behavior, as noted in the
above article:
When taking snapshots that include heaps and modules for a process other than
the current process, the CreateToolhelp32Snapshot function can fail or return
incorrect information for a variety of reasons. For example, if the loader data
table in the target process is corrupted or not initialized, or if the module
list changes during the function call as a result of DLLs being loaded or
unloaded, the function might fail with ERROR_BAD_LENGTH or other error code.
Ensure that the target process was not started in a suspended state, and try
calling the function again. If the function fails with ERROR_BAD_LENGTH when
called with TH32CS_SNAPMODULE or TH32CS_SNAPMODULE32, call the function again
until it succeeds.
This behavior necessitates calling DSO_pathbyaddr mutiple times to get a
succesful return code.
win32_pathbyaddr can be made more reliable, avoiding the need for multiple calls
by using alternate windows apis that are not/less succeptible to these transient
errors in multithreaded environments.
refactor win32_pathbyaddr here to implement that increased reliability.

Fix double-free in mlx_kem_dup() default case
Null mkey/xkey immediately after OPENSSL_memdup() so that any failure
path (including propq strdup) can safely call mlx_kem_key_free() without
risking a double-free on the source key's material. Use key->* rather
than ret->* for source-state checks to make ownership explicit.
Test that mlx_kem_dup() with partial key selection (e.g.
EVP_PKEY_PUBLIC_KEY) does not corrupt the original key's mkey/xkey
sub-objects. Covers X25519MLKEM768, SecP256r1MLKEM768,

Add memory allocation failure testing framework
Introduce ADD_MFAIL_TEST for exhaustive testing of allocation failure
handling in individual functions. The framework repeatedly calls the
test function, each time failing one allocation later within the
section bracketed by mfail_start() and mfail_end(), verifying that
every failure path returns 0 without crashing or leaking.
Custom allocators are installed once at startup via
CRYPTO_set_mem_functions(). When not armed, they pass through to
malloc/realloc/free. Installation can be disabled by setting
OPENSSL_TEST_MFAIL_DISABLE for tests that need the default allocator
(e.g. those using OPENSSL_MALLOC_FAILURES).
Additional environment variables control test execution:
OPENSSL_TEST_MFAIL_SKIP_ALL, OPENSSL_TEST_MFAIL_SKIP_SLOW,
OPENSSL_TEST_MFAIL_POINT, and OPENSSL_TEST_MFAIL_START.
