* Refactor dtls1_clear_queues()tb2020-09-261-25/+26
| | | | | | | | | | An upcoming cleanup diff by jsing needs dtls1_clear_queues() to be able to handle NULL pqueues. While one can easily add a NULL check to pqueue_pop(), this does not really fit in with the rest of the code. There are two kinds of while loops in dtls1_clear_queues that drain pqueues, so add two helper functions with a NULL check each. ok jsing

* Simplify call to ERR_print_errors_cb()tb2020-09-251-5/+4
| | | | | | | | | There is no reason for print_error()'s third argument to be a UI *. It may just as well be a void * to match what ERR_print_errors_cb() expects. This avoids casting the function pointer. Also, there's no need for a (void *) cast. ok jsing
* test-tls13-finished.py has 70 failing tests that expect a "decode_error"tb2020-09-251-6/+94
| | | | | | instead of the "decrypt_error" sent by tls13_server_finished_recv(). Both alerts appear to be reasonable in this context, so enable the tests while working around this.

* Error out if ok_chars and cancel_chars overlaptb2020-09-241-2/+4
| | | | | | | It is a bit silly to push an error on the stack without erroring out, so error out if the ok_chars and cancel_chars overlap. ok jsing
* Fix a number of leaks in the UI_dup_* functionstb2020-09-241-143/+99
| | | | | | | | | | | | | | | | | | | | | | | | | If any of general_allocate_{prompt,string,boolean}() fail, the UI_dup_* functions may leak the strings they strduped beforehand. Instead, use strdup inside these functions, so we can free as necessary. This makes the UI_add_* and UI_dup_* simple wrappers around general_allocate_{string,boolean}() that differ only in passing a Boolean that indicates whether or not to use strdup. Make a general cleanup pass over these functions, simplify the logic and make it overall a bit easier to follow. While there, use strcspn() instead of a handrolled variant. The only changes in behavior are that ERR_R_MALLOC_FAILURE is now pushed onto the stack a bit more often and that UI_dup_input_string() now returns -1 on failure to dup prompt like all the other UI_dup_* functions. This is not a problem since the manual already documents that errors are signaled with <= 0. The only consumer of this function according to Debian's codesearch is libp11, I sent them a PR to fix their (already broken) error handling. Addresses about 10 errors thrown by the LLVM static analyzer in ui/. ok jsing

* Release read and write buffers using freezero().jsing2020-09-244-21/+26
| | | | | | | | | Provide a ssl3_release_buffer() function that correctly frees a buffer and call it from the appropriate locations. While here also change ssl3_release_{read,write}_buffer() to void since they cannot fail and no callers check the return value currently. ok beck@ inoguchi@ tb@
* Ensure chain is set on the X509_STORE_CTX before triggering callback.jsing2020-09-231-12/+39
| | | | | | | | | | | | Various software expects the previous behaviour where the certificate chain is available on the X509_STORE_CTX when the verify callback is triggered. Issue hit by bket@ with lastpass-cli which has built in certificate pinning that is checked via the verify callback. Fix confirmed by bket@. ok beck@

This way we can skip testing openssl to openssl11 when running these manually by setting REGRESS_SKIP_SLOW to "yet" in mk.conf ok jsing@

| | | | | | | | | | | | | If the default path of the switch is taken, vname will not be added to the names list and will leak when it is set to NULL. Simplify the logic by eliminating the add Boolean. Instead, free and zero vname in the default case and continue the while loop directly. At the bottom of the switch, add vname to the names list unconditionally zero it out since it's now owned by names. Found by Guido Vranken's cryptofuzzer ok beck

| | | | | | | | | This is a convenience reacharound to libcrypto that trivially wraps X509_VERIFY_PARAM_get0_peername(). It is used by unbound 1.11.0 for better logging. As it's part of the API that landed with OpenSSL's DANE, more recent postfix snapshots use it as well. ok beck inoguchi jsing
* Prepare to provide stubbed out versions for reading/writing 0-RTT datatb2020-09-192-2/+41
| | | | | | | | | | | We do not support this feature but need to provide OpenSSL's API since software assumes it's available whenever TLS1_3_VERSION is available. These are minimal stubs that should have a decent chance to interact reasonably with software expecting the tricky upstream semantics, but this will have to be sorted out with runtime testing, so will likely have to be refined and revisited. ok beck jsing

* If ssl_cert_dup() fails in SSL_set_SSL_CTX(3), return failureschwarze2020-09-181-5/+10
| | | | | | | | | | | | | | | | rather than silently leaving a NULL pointer in ssl->cert. Kurt Roeckx fixed the same bug similarly in OpenSSL in 2015. While here, (1) make the code easier to read and more robust by returning right away when ssl still uses the context it was created from and the ctx argument is NULL, rather than doing a lot of work that changes nothing unless data is already corrupt, and (2) use the shorter and more inituitive SSL_CTX_up_ref(3) rather than manually calling CRYPTO_add(3), which means no functional change and is also in the OpenSSL 1.1 branch.
