* Optimise bn_mul2_mulw_addtw() for aarch64.jsing2023-06-171-1/+28
| | | | | This provides significant performance gains for bn_sqr_comba4() and bn_sqr_comba8().
* Speed up Montgomery multiplication.jsing2023-06-171-10/+37
| | | | | | | | | | Factor out and optimise the inner loop for Montgomery multiplication, making use of bn_qwmulw_addqw_addw() to perform Montgomery multiplication by one word in larger steps. This provides a significant performance gain, especially on platforms where bn_qwmulw_addqw_addw() is (or can be) optimised. ok tb@

* Some fixes in ASN1_item_verify()tb2023-06-151-17/+8
| | | | | | | | Switch to using EVP_DigestVerify(). Move the freeing of in where it belongs (previously it would leak on EVP_DigestVerifyUpdate() failure), and use the proper idiom for ASN1_item_i2d() error checking. ok jsing

* Rename a few variables and other cosmeticstb2023-06-151-23/+21
| | | | | | | Rename buf_in into in, buf_out into out, use in_len and out_len for their lengths, drop a couple of silly casts and remove some empty lines. ok jsing
* Switch ASN1_item_sign_ctx() to EVP_DigestSign()tb2023-06-151-9/+7
| | | | | | | | | This makes this function work with Ed25519 and cleans up a handful of ugly contortions: use EVP_DigestSign() to determine the signature length instead of using the strange EVP_PKEY_size() and garbage collect the now useless out_len. Also use calloc(). ok jsing
* Make NULL checks explicit in ASN1_item_sign_ctx()tb2023-06-151-6/+8
| | | | | | | Also move the NULL check for the EVP_MD into the rv == 2 path, which is the only branch where it is used. ok jsing
* ASN1_item_sign_ctx()tb2023-06-151-3/+7
| | | | | | Pull a NULL check for pkey->ameth up to before ameth is first accessed. An EVP_PKEY created with EVP_PKEY_new() has ameth == NULL, so this check makes sense, but it does not make sense to do it where it was.
* Fix a logic error in ASN1_item_sign_ctx()tb2023-06-151-5/+8
| | | | | | | | | | | If the item_sign() ASN.1 method returns 1, it supposedly handles everything and the goto err prior to r1.5 was actually a success path. Go figure. This is fortunately inconsequential since there are only two item_sign() methods, one for RSA and one for Ed25519, neither of which can return 1. They only return 0, 2, and 3. Pointed out by and ok jsing
* Move comment about ASN1_item_dup() where it belongstb2023-06-131-7/+7
| | | | | Reword it in such a way that it stands on its own and doesn't refer to a non-existent model above. Also tweak grammar and fix typos.
* Disallow aliasing of return value and modulustb2023-06-131-1/+44
| | | | | | | | | | | All the functions changed in this commit would silently misbehave if the return value aliases the modulus, most of the time they would succeed and return an incorrect result of 0 in that situation. This adjusts all the functions in BN_mod.c, others and documentation will follow later. Prompted by a bug report about BN_mod_inverse() by Guido Vranken. ok jsing
* Add a BN_R_INVALID_ARGUMENT error codetb2023-06-132-2/+4
| | | | | | | | | | One problem with OpenSSL error codes is that they tend to be too specific (another problem is that they are extremely ugly). So add an EINVAL-style error code. This will be used in an upcoming commit to disallow aliasing of the 'return value' with the modulus in BN_mod_* functions and should be applicable elsewhere, outside of this one narrow use case. ok jsing

| | | | | | | | This includes bn_qwaddqw(), bn_qwsubqw(), bn_qwmulw_addw() and bn_qwmulw_addqw_addw(). These can typically be optimised on architectures that have a reasonable number of general purpose registers. ok tb@
* Convert legacy server kex to one-shot sign/verifytb2023-06-112-47/+62
| | | | | | | | | | This converts ssl3_{get,send}_server_key_exchange() to EVP_DigestVerify() and EVP_DigestSign(). In order to do this, build the full signed_params up front and rework the way the key exchange parameters are constructed. This way we can do the verify and sign steps in one go and at the same use a more idiomatic approach with CBB/CBS. with/ok jsing

* In 1995, Eric A. Young chose a confusing name for the "lastUpdate" fieldschwarze2023-06-062-12/+20
| | | | | | | | | | | | | | | of the X509_CRL_INFO object. It should have been called "thisUpdate" like in RFC 5280 section 5.1 (and in its precursor RFC 2459). Then again, RFC 2459 was only published in 1999, so maybe the terminology wasn't firmly established yet when Young wrote his code several years earlier - just guessing, neither we nor the OpenSSL folks appear to know the real reasons... Anyway, we have been stuck with the "lastUpdate" names in the API for more than two decades now, so clarify in the documentation what they refer to and what they really mean. Requested by and OK tb@.

| | | | | | | | | | Suggestion from Małgorzata Olszówka, they noted: "The original wording suggests that it is required to execute CMS_get0_signers() after CMS_verify(), while it is CMS_get0_signers() that requires prior successful invocation of CMS_verify()." OK tb@
* Reinstate bn_isqrt.c r1.8 and crypto_lock.c r1.3tb2023-06-042-8/+5
| | | | | | | | | | | | | | | This traded local copies of CTASSERT() to the one in crypto_internal.h. This change was backed out due to SHA-512 breakage on STRICT_ALIGNMENT architectures still using Fred Flintstone's gcc without asm sha512. Original commit message: Use crypto_internal.h's CTASSERT() Now that this macro is available in a header, let's use that version rather than copies in several .c files. discussed with jsing

* More thorough write-afetr-free checks.otto2023-06-043-25/+54
| | | | | | | | | | | | | | | | | | | On free, chunks (the pieces of a pages used for smaller allocations) are junked and then validated after they leave the delayed free list. So after free, a chunk always contains junk bytes. This means that if we start with the right contents for a new page of chunks, we can *validate* instead of *write* junk bytes when (re)-using a chunk. With this, we can detect write-after-free when a chunk is recycled, not justy when a chunk is in the delayed free list. We do a little bit more work on initial allocation of a page of chunks and when re-using (as we validate now even on junk level 1). Also: some extra consistency checks for recallocaray(3) and fixes in error messages to make them more consistent, with man page bits. Plus regress additions.
* Add regress coverage for BN_mod_inverse()tb2023-06-032-1/+387
| | | | | This would detect the aliasing issue reported by Guido Vranken fixed in bn_gcd.c r1.28. Most testcases are from BoringSSL's regress test.
* Fix variable reuse in BN_mod_inverse()tb2023-06-021-21/+15
| | | | | | | | | | | | | | | | | | The somewhat strange calculation m = a^{-1} (mod m) can return 0. This breaks because of BN_nnmod() having delicate semantics of which variable can be reused. BN_nnmod(a, a, m, ctx) works and the library relies on that. Here, the code ends up doing BN_nnmod(m, a, m, ctx) and this doesn't work. If the result of the initial BN_mod() is negative, then BN_nnmod() will return 0. Problem reported by Guido Vranken in https://github.com/openssl/openssl/issues/21110 This code is well covered by regress, but it does not currently have explicit test coverage. Such will be added soon. ok beck jsing

* Check for X509_get_ext_d2i() failuretb2023-06-011-4/+10
| | | | | | | | | | X509_get_ext_d2i() (or rather X509V3_get_d2i()) can return NULL for various reasons. If it fails because the extension wasn't found, it sets *crit = -1. In any other case, e.g., the cert is bad or we ran out of memory in X509V3_EXT_d2i(), crit is set to something else, so we should actually error. ok jsing
* Avoid a potentially overflowing checktb2023-06-011-2/+2
| | | | | | | | | | | | This doesn't actually overflow, but still is poor style. Speaking of which: this is now the second time I get to fix something reported by Nicky Mouha by way of a blog post. The first time was the actual SHA-3 buffer overflow in Python where it is not entirely clear who screwed up and how. Hopefully next time proper communication will happen and work. ok jsing
