The aes128_cbc_hmac_sha1 cipher in the dasync engine is broken. Probably by commit e38c2e85 which removed use of the "enc" variable...but not completely. Reviewed-by:

This commit adds a simple unit test to make sure that the constant-time flag does not "leak" among BN_CTX frames: - test_ctx_consttime_flag() initializes (and later frees before returning) a BN_CTX object, then it calls in sequence test_ctx_set_ct_flag() and test_ctx_check_ct_flag() using the same BN_CTX object. The process is run twice, once with a "normal" BN_CTX_new() object, then with a BN_CTX_secure_new() one. - test_ctx_set_ct_flag() starts a frame in the given BN_CTX and sets the BN_FLG_CONSTTIME flag on some of the BIGNUMs obtained from the frame before ending it. - test_ctx_check_ct_flag() then starts a new frame and gets a number of BIGNUMs from it. In absence of leaks, none of the BIGNUMs in the new frame should have BN_FLG_CONSTTIME set. In actual BN_CTX usage inside libcrypto the leak could happen at any depth level in the BN_CTX stack, with varying results depending on the patterns of sibling trees of nested function calls sharing the same BN_CTX object, and the effect of unintended BN_FLG_CONSTTIME on the called BN_* functions. This simple unit test abstracts away this complexity and verifies that the leak does not happen between two sibling functions sharing the same BN_CTX object at the same level of nesting. Reviewed-by:

Because test order can be randomized, running foo_init() as a separate test is unsafe practice. Instead, we make it possible to call it multiple times, and call it at the start of each separate test. Reviewed-by:

- Add a bit more text about that is expected of the user or OSSL_METHOD_STOREs. - Clarify what a method and what a numeric identity are. - Change all mentions of 'implementation' and 'result' to 'method'. To clarify further: OpenSSL has used the term 'method' for structures that mainly contains function pointers. Those are the methods that are expected to be stored away in OSSL_METHOD_STOREs. In the end, however, it's the caller's responsibility to define exactly what they want to store, as long as its 'methods' are associated with a numeric identity and properties. Reviewed-by:

Properties are a sequence of comma separated name=value pairs. A name without a corresponding value is assumed to be a Boolean and have the true value 'yes'. Values are either strings or numbers. Strings can be quoted either _"_ or _'_ or unquoted (with restrictions). There are no escape characters inside strings. Number are either decimal digits or '0x' followed by hexidecimal digits. Numbers are represented internally as signed sixty four bit values. Queries on properties are a sequence comma separated conditional tests. These take the form of name=value (equality test), name!=value (inequality test) or name (Boolean test for truth). Queries can be parsed, compared against a definition or merged pairwise.

The add/double shortcut in ecp_nistz256-x86_64.pl left one instruction point that did not unwind, and the "slow" path in AES_cbc_encrypt was not annotated correctly. For the latter, add .cfi_{remember,restore}_state support to perlasm. Next, fill in a bunch of functions that are missing no-op .cfi_startproc and .cfi_endproc blocks. libunwind cannot unwind those stack frames otherwise. Finally, work around a bug in libunwind by not encoding rflags. (rflags isn't a callee-saved register, so there's not much need to annotate it anyway.) These were found as part of ABI testing work in BoringSSL. Reviewed-by: -

This commit adds a dedicated function in `EC_METHOD` to access a modular field inversion implementation suitable for the specifics of the implemented curve, featuring SCA countermeasures. The new pointer is defined as: `int (*field_inv)(const EC_GROUP*, BIGNUM *r, const BIGNUM *a, BN_CTX*)` and computes the multiplicative inverse of `a` in the underlying field, storing the result in `r`. Three implementations are included, each including specific SCA countermeasures: - `ec_GFp_simple_field_inv()`, featuring SCA hardening through blinding. - `ec_GFp_mont_field_inv()`, featuring SCA hardening through Fermat's Little Theorem (FLT) inversion. - `ec_GF2m_simple_field_inv()`, that uses `BN_GF2m_mod_inv()` which already features SCA hardening through blinding. From a security point of view, this also helps addressing a leakage previously affecting conversions from projective to affine coordinates. This commit also adds a new error reason code (i.e., `EC_R_CANNOT_INVERT`) to improve consistency between the three implementations as all of them could fail for the same reason but through different code paths resulting in inconsistent error stack states.

(*) so far *some* modules were compiled as .code 32 even if Thumb-2 was targeted. It works at hardware level because processor can alternate between the modes with no overhead.

safestack.h, lhash.h and sparse_array.h all define macros to generate a full API for the containers as static inline functions. This potentially generates unused code, which some compilers may complain about. We therefore need to mark those generated functions as unused, so the compiler knows that we know, and stops complaining about it. Reviewed-by:

Add SSL_OP64_NO_EXTENDED_MASTER_SECRET, that can be set on either an SSL or an SSL_CTX. When processing a ClientHello, if this flag is set, do not indicate that the EMS TLS extension was received in either the ssl3 object or the SSL_SESSION. Retain most of the sanity checks between the previous and current session during session resumption, but weaken the check when the current SSL object is configured to not use EMS. Reviewed-by:

This makes `--strict-warnings` into a compiler pseudo-option, i.e. it gets treated the same way as any other compiler option given on the configuration command line, but is retroactively replaced by actual compiler warning options, depending on what compiler is used. This makes it easier to see in what order options are given to the compiler from the configuration command line, i.e. this: ./config -Wall --strict-warnings would give the compiler flags in the same order as they're given, i.e.: -Wall -Werror -Wno-whatever ... instead of what we got previously: -Werror -Wno-whatever ... -Wall Reviewed-by:

The "verify_return_error" option in s_client is documented as: Return verification errors instead of continuing. This will typically abort the handshake with a fatal error. In practice this option was ignored unless also accompanied with the "-verify" option. It's unclear what the original intention was. One fix could have been to change the documentation to match the actual behaviour. However it seems unecessarily complex and unexpected that you should need to have both options. Instead the fix implemented here is make the option match the documentation so that "-verify" is not also required. Note that s_server has a similar option where "-verify" (or "-Verify") is still required. This makes more sense because those options additionally request a certificate from the client. Without a certificate there is no possibility of a verification failing, and so "-verify_return_error" doing nothing seems ok. Fixes #8079 Reviewed-by:
