2021-12-24Add initial test coverage for RFC 3779 code.tb2-0/+1804
This exercises the code paths that are reached from the validator and also tests that the public API behaves as expected. There is a lot more that could be done here, but this test is already big enough. Missing are tests for X509v3_{addr,asid}_validate_{path,resource_set}() themselves. One test failure is ignored and will be fixed in the near future when a bad logic error in range_should_be_prefix() is fixed. A consequence of this bug is that we will currently accept and generate DER that doesn't conform to RFC 3779.
2021-12-24Fix some KNF issues in the RFC 3779 section that have bothered me fortb1-54/+55

2021-12-24Remove asserts from asid_validate_path_internal()tb1-11/+22
The first asserts ensure that things checked in the callers hold true. Turn them into error checks and set the error on the X509_STORE_CTX if it's present. Checking sk_value(..., i) with i < sk_num(...) isn't useful, particularly if that check is done via an assert. Turn one remaining assert into a NULL check. Finally, simplify the sk_num() checks in the callers. ok jsing
2021-12-24Turn asserts in ASIdentifierChoice_canonize() into error checkstb1-3/+5
The first assert ensures that a stack that was just sorted in a stronger sense is sorted in a weak sense and the second assert ensures that the result of the canonization procedure is canonical. All callers check for error, so these asserts don't do anything useful. ok jsing

2021-12-24Remove asserts from addr_validate_path_internal()tb1-9/+19
This is reachable from x509_verify(), but all asserts are previously checked in the caller. Turn them into error checks and make sure the error is set on the X509_STORE_CTX if present. Change some stack == NULL || sk_num(stack) == 0 checks into sk_num(stack) <= 0 which is equivalent but simpler. ok jsing
2021-12-24Turn assert in X509v3_addr_canonize() into an error check.tb1-3/+5
All internal callers check the return value and future external callers will be happy not to hit an assert from the library. ok jsing
2021-12-23Fully check the second strtoul() call in v2i_IPAddrBlocks()tb1-3/+34
This can read a value in an arbitrary base from a string that is supposed to be followed by whitespace or a colon, so it cannot be switched to strtonum(). The current checks don't allow a read past the end, but let's use the standard idiom instead. ok jsing
2021-12-23Fix an arbitrary out-of-bounds stack read in v2i_IPAddrBlocks()tb1-3/+7
Switch an insufficiently checked strtoul() to strtonum(). This can be used to trigger a read of a user-controlled size from the stack. $ openssl req -new -addext 'sbgp-ipAddrBlock = IPv4:192.0.2.0/12341234' Segmentation fault (core dumped) The bogus prefix length 12341234 is fed into X509v3_addr_add_prefix() and used to read (prefixlen + 7) / 8 bytes from the stack variable 'min[16]' that ends up as 'data' in the memmove in ASN1_STRING_set(). The full fix will add length checks to X509v3_addr_add_prefix() and make_addressPrefix() and will be dealt with later. The entire X509v3_{addr,asid}_* API will need a thorough review before it can be exposed. This code is only enabled in -current and can only be reached from openssl.cnf files that contain sbgp-ipAddrBlock or from the openssl(1) command line. ok jsing

2021-12-18Document BN_abs_is_word(3).schwarze1-5/+21
While here, add the missing "const" qualifier to the second parameter of BN_is_word(3) - even though i doubt that marking an integral type parameter as "const" serves any significant purpose... Note that the OpenSSL documentation for this function that Billy Brumley committed on August 4, 2021 is actually wrong. Essentially, it says "BN_abs_is_word() test[s] if a equals ... |w|." Now pray tell me, what exactly is the point of taking the absolute value of an unsigned integer number? To compensate for the obvious absurdity of his patch, Billy made a point of getting *three* OKs from rather notable people: Pauli Dale, Nicola Tuveri, and Dmitry Belyavskiy. I believe this is a striking example of the cavalier attitude some projects put on display when it comes to documentation, and also a striking example of how bad documentation can occasionally be worse than no documentation at all, because the OpenSSL manual page will now thoroughly confuse anyone reading it. SCNR pointing out this (hopefully unintentional) hilarity - or is this an attempt at trolling the readers of their documentation? If it is, they certainly got me.

2021-12-16unifdef TLS13_USE_LEGACY_CLIENT_AUTHtb1-9/+1
Before the TLSv1.3 stack grew client certificate support, it fell back to the legacy stack. Proper client certificate support was added in a2k20 with a TLS13_USE_LEGACY_CLIENT_AUTH knob to provide an easy fallback in case the new code should have a problem. This was never needed. As ifdefed code is wont to do, this bitrotted a few months later when the client and server methods were merged. discussed with jsing
