* avio: Copy URLContext generic options into child URLContextsMartin Storsjö2016-03-24
| | | | | | | | | | | | | | | Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>
* urlprotocol: receive a list of protocols from the callerAnton Khirnov2016-02-22
| | | | | This way, the decisions about which protocols are available for use in any given situations can be delegated to the caller.
* lavf: split tls.cwm42015-05-26
| | | | | | | | Move the OpenSSL and GnuTLS implementations to their own files. Other than the connection code (including options) and some boilerplate, no code is actually shared. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: fix compilation when both gnutls and openssl are enabledJames Almer2015-05-22

* tls: Remove all the local polling loopsMartin Storsjö2015-05-22
| | | | | | These aren't necessary any longer. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Remove the nonblocking codeMartin Storsjö2015-05-22
| | | | | | | | Since the underlying URLContext read functions are used, they handle interruption, without having to handle it at this level. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Use custom IO to read from the URLContextMartin Storsjö2015-05-22
| | | | | | | | | | | | | | This avoids hijacking the fd, by reading using the normal URLContext functions instead. This allowing reading data that has been buffered in the underlying URLContext. This avoids using the libraries own send functions that can cause SIGPIPE. The fd is still used for polling the lowlevel socket, for waiting for retries.

* tls: Add support for listen modeMartin Storsjö2013-09-26
| | | | | | | | | Also add options for specifying a certificate and key, which can be used both when operating as client and as server. Partially based on a patch by Peter Ross. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Add options for verifying the peer certificateMartin Storsjö2013-09-26
| | | | | | | | | | | | | | | | | | | | A file containing the trusted CA certificates needs to be supplied via the ca_file AVOption, unless the TLS library has got a system default file/database set up. This doesn't check the hostname of the peer certificate with openssl, which requires a non-trivial piece of code for manually matching the desired hostname to the string provided by the certificate, not provided as a library function. That is, with openssl, this only validates that the received certificate is signed with the right CA, but not that it is the actual server we think we're talking to. Verification is still disabled by default since we can't count on a proper CA database existing at all times. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: Handle the environment variable no_proxy more properlyMartin Storsjö2013-02-27
| | | | | | | | | | | | | | | | | | | | The handling of the environment variable no_proxy, present since one of the initial commits (de6d9b6404), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Return AVERROR_EOF if the TLS_read/write functions return 0Martin Storsjö2012-07-28
| | | | | | | | | | OpenSSL returns 0 when the peer has closed the connection. GnuTLS doesn't return that though, but returns GNUTLS_E_UNEXPECTED_PACKET_LENGTH if the connection simply is closed without a clean close notify packet.

* tls: Use TLSv1_client_method for OpenSSLMartin Storsjö2011-11-17
| | | | | | | | | | | | | TLSv1 is compatible with SSLv3, so this doesn't change much in terms of compatibility. By explicitly using TLSv1, OpenSSL sends the server name indication (SNI) header, which we already set using SSL_set_tlsext_host_name (earlier, this didn't have any effect). SNI allows servers to serve SSL content for different host names with separate certificates on one single port (vhosts). Signed-off-by: Martin Storsjö <martin@martin.st>
* avio: add support for passing options to protocols.Anton Khirnov2011-11-13

* tls: Use ERR_get_error() in do_tls_pollMartin Storsjö2011-11-08
| | | | | | | | | | The return value ret isn't an error code that can be passed to ERR_error_string(). This makes the error messages printed actually contain useful information. Signed-off-by: Martin Storsjö <martin@martin.st>
* avformat: Add the tls protocol, using OpenSSL or gnutlsMartin Storsjö2011-11-05
Note, this protocol doesn't yet check verify the server certificate against a local database of trusted CA root certificates. Signed-off-by: Martin Storsjö <martin@martin.st>
