The MULTIBLOCK code uses a "jumbo" sized write buffer which it allocates and then frees later. Pipelining however introduced multiple pipelines. It keeps track of how many pipelines are initialised using numwpipes. Unfortunately the MULTIBLOCK code was not updating this when in deallocated its buffers, leading to a buffer being marked as initialised but set to NULL. RT#4618 Reviewed-by: -

Update the documentation for the newly renamed and modified SSL_set0_rbio() and SSL_set0_wbio() functions. State that they should be preferred over SSL_set_bio(). Attempt to document the ownership rules for SSL_set_bio(). Reviewed-by: -
Matt Caswell authored
SSL_set_rbio() and SSL_set_wbio() are new functions in 1.1.0 and really should be called SSL_set0_rbio() and SSL_set0_wbio(). The old implementation was not consistent with what "set0" means though as there were special cases around what happens if the rbio and wbio are the same. We were only ever taking one reference on the BIO, and checking everywhere whether the rbio and wbio are the same so as not to double free. A better approach is to rename the functions to SSL_set0_rbio() and SSL_set0_wbio(). If an existing BIO is present it is *always* freed regardless of whether the rbio and wbio are the same or not. It is therefore the callers responsibility to ensure that a reference is taken for *each* usage, i.e. one for the rbio and one for the wbio. The legacy function SSL_set_bio() takes both the rbio and wbio in one go and sets them both. We can wrap up the old behaviour in the implementation of that function, i.e. previously if the rbio and wbio are the same in the call to this function then the caller only needed to ensure one reference was passed. This behaviour is retained by internally upping the ref count. This commit was inspired by BoringSSL commit f715c423224. RT#4572 Reviewed-by: -

This adds some simple SSL BIO tests that check for pushing and popping of BIOs into the chain. These tests would have caught the bugs fixed in the previous three commits, if combined with a crypto-mdebug build. Reviewed-by: -

The BIO_pop implementation assumes that the rbio still equals the next BIO in the chain. While this would normally be the case, it is possible that it could have been changed directly by the application. It also does not properly cater for the scenario where the buffering BIO is still in place for the write BIO. Most of the existing BIO_pop code for SSL BIOs can be replaced by a single call to SSL_set_bio(). This is equivalent to the existing code but additionally handles the scenario where the rbio has been changed or the buffering BIO is still in place. Reviewed-by: -

When pushing a BIO onto an SSL BIO we set the rbio and wbio for the SSL object to be the BIO that has been pushed. Therefore we need to up the ref count for that BIO. The existing code was uping the ref count on the wrong BIO. Reviewed-by: -

When setting the read bio we free up any old existing one. However this can lead to a double free if the existing one is the same as the write bio. Reviewed-by: -

SSLv2 is no longer supported in 1.1.0, however we *do* still accept an SSLv2 style ClientHello, as long as we then subsequently negotiate a protocol version >= SSLv3. The record format for SSLv2 style ClientHellos is quite different to SSLv3+. We only accept this format in the first record of an initial ClientHello. Previously we checked this by confirming s->first_packet is set and s->server is true. However, this really only tells us that we are dealing with an initial ClientHello, not that it is the first record (s->first_packet is badly named...it really means this is the first message). To check this is the first record of the initial ClientHello we should also check that we've not received any data yet (s->init_num == 0), and that we've not had any empty records.

8605abf1 fixed the nval leak, but it used free instead of pop_free. nval owns its contents, so it should be freed with pop_free. See the pop_free call a few lines down. This is a no-op as, in this codepath, we must have nval == NULL or sk_CONF_VALUE_num(nval) == 0. In those cases, free and pop_free are identical. However, variables should be freed consistently.

Some versions of the Microsoft TLS stack have problems when the DHE public key is encoded with fewer bytes than the DHE prime. There's some public acknowledgement of the bug at these links: https://connect.microsoft.com/IE/feedback/details/1253526/tls-serverkeyexchange-with-1024-dhe-may-encode-dh-y-as-127-bytes-breaking-internet-explorer-11 https://connect.microsoft.com/IE/feedback/details/1104905/wininet-calculation-of-mac-in-tls-handshake-intermittently-fails-for-dhe-rsa-key-exchange This encoding issue also causes the same errors with 2048-bit DHE, if the public key is encoded in fewer than 256 bytes and includes the TLS stack on Windows Phone 8.x.

This adds the functions X509_set_proxy_pathlen(), which sets the internal pc path length cache for a given X509 structure, along with X509_get_proxy_pathlen(), which retrieves it. Along with the previously added X509_set_proxy_flag(), this provides the tools needed to manipulate all the information cached on proxy certificates, allowing external code to do what's necessary to have them verified correctly by the libcrypto code.

We only add setters for X509_STORE function pointers except for the verify callback function. The thought is that the function pointers in X509_STORE_CTX are a cache for the X509_STORE functions. Therefore, it's preferable if the user makes the changes in X509_STORE before X509_STORE_CTX_init is called, and otherwise use the verify callback to override any results from OpenSSL's internal calculations.
