* In x509_vfy.h rev. 1.37 and x509_vfy.c rev. 1.91, tb@ providedschwarze2021-11-179-46/+209
| | | | | | | | | | | | | | | | | X509_STORE_CTX_set_verify(3) and X509_STORE_CTX_get_verify(3). Document them. In the next bump, tb@ will also provide X509_STORE_CTX_verify_fn(3) and X509_STORE_set_verify(3) and restore X509_STORE_set_verify_func(3) to working order. For efficiency of documentation work, already document those three, too, but keep the text temporariy .if'ed out until they become available. Delete X509_STORE_set_verify_func(3) from X509_STORE_set_verify_cb_func(3) because it was misplaced in that page: it is not related to the verification callback. tb@ agrees with the general direction.

* Fix a strange check in the auto DH codepathtb2021-11-141-3/+5
| | | | | | | | | | The code assumes that the server certificate has an RSA key and bases the calculation of the size of the ephemeral DH key on this assumption. So instead of checking whether we have any key by inspecting the dh part of the union, let's check that we actually have an RSA key. While here, make sure that its length is non-negative. ok jsing

| | | | | | | | | | | | | | | | | | | | | | | verification, accepting CRLs that ought to be rejected, if an unusual combination of verification flags was specified. If time verification was explicitly requested with X509_V_FLAG_USE_CHECK_TIME, it was skipped on CRLs if X509_V_FLAG_NO_CHECK_TIME was also set, even though the former is documented to override the latter both in the OpenSSL and in the LibreSSL X509_VERIFY_PARAM_set_flags(3) manual page. The same bug in x509_check_cert_time() was already fixed by beck@ in rev. 1.57 on 2017/01/20. This syncs the beginning of the function check_crl_time() with the OpenSSL 1.1.1 branch, which is still under a free license. OK beck@ This teaches that having too many flags and options is bad because they breed bugs, and even more so if they are poorly designed to override each other in surprising ways.

If the three X509_load_*(3) functions are called with a NULL file argument, do not return 1 to the caller because the return value 1 means "i loaded one certificate or CRL into the store". 2. When calling PEM load functions, do not ask the user for a password in an interactive manner.

| | | | | | | | | | | | | | | out of X509_LOOKUP_hash_dir(3) because both groups of functions differ substantially in purpose and structure. Rewrite the complete text of X509_load_cert_file(3) from scratch for correctness and clarity. This fixes several documentation errors: 1. The names of the constants were wrong, lacking the "X509_" prefix. 2. None of these functions support X509_FILETYPE_DEFAULT, neither in OpenSSL nor in LibreSSL. 3. The memory cache does not contain X509_STORE objects; instead, the X509_STORE object *is* the memory cache.

| | | | | | | | | | | | | | Get rid of the last X509_OBJECT_free_contents() call by moving the object from the stack to the heap. I deliberately kept the obj variable to keep obj and pobj separate. Rename the out parameter from issuer to out_issuer to ensure that we only assign it when we have acquired a reference that we can return. Add a new X509 *issuer. In the first part of the function, acquire an extra reference before check_issuer/check_time. In the second part of the function, acquire a reference inside the lock to avoid a race. Deal with ret only in one place. ok jsing

* First pass of streamlining X509_STORE_get1_{certs,crls}()tb2021-11-051-66/+77
| | | | | | | | | | | | | | These functions are quite messy. On top of the tricky logic querying the cache, then refreshing the cache (unconditionally or not), then querying again, then extracting a list of certs/crls and bumping their refcounts, things are intermixed with locking and needlessly early allocations that then need to be cleaned up again. Use X509_STORE_CTX_get_obj_by_subject() to avoid using an object on the stack and defer allocation of the returned stack of certs to later. Flatten the logic a bit and prepare for further refactoring. ok jsing

* Clean up X509_STORE_add_{cert,crl}().tb2021-11-051-69/+41
| | | | | | | | | | | | | | | | | | | | Add a X509_STORE_add_object() function that adds an X509 object to the store and takes care of locking and cleaning up. This way we can set up an X509_OBJECT for both the cert and CRL case and hand over to the new function. There is one intentional change of behavior: if there is an attempt to add an object which is already present in the store, succeed instead of throwing an error. This makes sense and is also the OpenSSL behavior. As pointed out by jsing, this is a partial fix for the long standing GH issue #100 on libtls where connections would fail if the store contains duplicate certificates. Also: remove the internal X509_OBJECT_dec_ref_count(), which is no longer used. ok jsing
