2023-10-11Rewrite X509_ALGOR_set0()tb1-17/+13
The current implementation is a complete mess. There are three cases: 1) ptype == V_ASN1_UNDEF: parameter must be freed and set to NULL. 2) ptype == 0: existing non-NULL parameters are left untouched, NULL parameters are replaced with ASN1_TYPE_new()'s wacky defaults. 3) otherwise allocate new parameters if needed and set them to ptype/pval. In all three cases free the algorithm and set it to aobj. The challenge now is to implement this using nine if statements and one else clause... We can do better. This preserves existing behavior. There would be cleaner implementations possible, but they would change behavior. There are many callers in the ecosystem that do not error check X509_ALGOR_set0() since OpenSSL failed to do so. So this was carefully rewritten to leave alg in a consisten state so that unchecking callers don't encounter corrupted algs. ok jsing
2023-10-11x509_algor: Turn expected failure into actual failure now that the API istb1-3/+3
fixed.
2023-10-11Ensure that out_value is initialized even if out_type is NULLtb1-1/+5
This fixes the printf in the x509_algor regress. ok jsing
2023-10-11Rewrite X509_ALGOR_get0()tb1-13/+19
Make the logic slightly less convoluted. Preserve the behavior that *ppval remains unset if pptype == NULL for now. However, ensure that *ppval is set to NULL if pptype is V_ASN1_UNDER. ok jsing
2023-10-11Add internal version of X509_ALGOR_set_md()tb2-7/+17
X509_ALGOR_set_md() is a void function that cannot easily be error checked. The caller has to jump through hoops to make sure this function doesn't fail. Prepare replacing this internally with X509_ALGOR_set_evp_md(), which allows error checking. There is one slight change of behavior: if the EVP_MD object passed in does not have an OID known to the library, then this new API fails. It is unclear what the library should do with such an object and people who use EVP_MD_meth_new() need to know what they are doing anyway and they are better off teaching the lib about the OID if they're going to be messing with certs. Oh, and the prototype is in x509_local.h because the rest of this API is in x509.h despite being implemented in asn1/. ok jsing

2023-10-11Clean up X509_ALGOR_cmp()tb1-10/+10
This is currently written in what is likely the most stupid way possible. Rewrite this function in a more straightforward way. ok jsing
2023-10-11Add regress coverage for X509_ALGOR_*tb2-2/+377
This covers the setters and getters. Serialization and deserialization as well as comparison is already well covered by the pieces of regress using certs. There is currently one printf indicating failure. This will be fixed shortly.
2023-10-11I forgot that we now have ASN1_INTEGER_set_uint64()tb1-13/+6
2023-10-11Be more precise about X509_ALGOR_get0()tb1-11/+26
2023-10-10Improve X509_ALGOR_new(3) documentationtb1-14/+33
The previous wording was misleading since the result of X509_ALGOR_new() is not actually an empty X509_ALGOR object. Rather, it contains the undefined ASN1_OBJECT returned by OBJ_nid2obj(NID_undef). Therefore using X509_ALGOR_get0(3) for error checking X509_ALGOR_set_md() is not trivial. So: change the initial paragraph into a general intro referring to the OpenSSL API needed to interface with X509_ALGOR and write a new paragraph documenting X509_ALGOR_new(3) and drop the incorrect suggestion of an error check. Notably there's now a reference to the OBJ_nid2obj() family without which one cannot really use X509_ALGOR_* for anything at all. With and ok schwarze

2023-10-09Clarify documentation of X509_ALGOR_{set0,set_md}()tb1-7/+45
The X509_ALGOR_set0() and X509_ALGOR_set_md() documentation comes from upstream, which means it is as sloppy as the code and as vague as your average upstream manpage. Be precise on what X509_ALGOR_set0() does on different inputs and document return values and failure modes. X509_ALGOR_set_md() is a void function that calls X509_ALGOR_set0() in a way that can fail, leaving alg in a corrupted state. Document when that can occur and how to avoid or detect that, but do not go too far, because EVP_MD_meth_new(), one potential source of failures, is a whole another can of worms. joint work with schwarze

ASN1_UTCTIME_cmp_tim_t() could be done similarly, but then I have to mess with LIBRESSL_INTERNAL. Let's do this after unlock.

2023-10-01Fix a copy-paste bug in ASN1_TIME_compare()tb1-2/+2
ASN1_TIME_compare() compares two times t1 and t2. Due to a copy-paste error, we would do ASN1_time_parse(t1->data, t2->length, &tm2, t2->type) Now if t1 is a UTCTime (length 13) and t2 is a GeneralizedTime (length 15), the worst that could happen is a 2-byte out-of-bounds read. Fortunately, t1 will already have parsed as a UTCTime, so it will have a Z where there should be the first digit of the seconds for a GeneralizedTime and we will error out. Now if both t1 and t2 have the same type, we will parse t1's data twice and we will return an incorrect comparison. This could have some security impact if anything relied on this function for security purposes. It is unused in our tree and unused in our ports tree ports and the only consumer I could find was some MongoDB things doing OCSP, so this won't be too bad. Then of course there's also the language bindings. Issue reported by Duncan Thomson at esri dot com via libressl-security ok beck deraadt
2023-10-01Document EVP_CIPHER_CTX_iv_length() return valuestb1-3/+7
We aligned with upstream behavior. Let's document it properly. Surprisingly, OpenSSL 1.1 half-assed the docs: two parts of the manual contradict each other. The part getting EVP_CIPHER_CTX_iv_length() right, incorrectly documents possible -1 return value to EVP_CIPHER_iv_length(). OpenSSL 3 documentation improvement efforts seem to have tried to address this issue with the result that the manual is now entirely wrong when it comes to the EVP_CIPHER_CTX_iv_length() replacement. Par for the course.

2023-09-29Allow IP addresses to be specified in a URI.beck3-19/+70
Our checking here was a bit too aggressive, and did not permit an IP address in a URI. IP's in a URI are allowed for things like CRLdp's AIA, SAN URI's etc.). The check for this was also slightly flawed as we would permit an IP if memory allocation failed while checking for an IP. Correct both issues. ok tb@

These were the last four RFC 3779 things that check_complete.pl x509v3 complained about. I will surely tweak and try to improve a few things in the coming days, but the pages should now be stable enough that review efforts will likely not be wasted. Any feedback appreciated.
