ssl:ssl_accept/2 timeout is no longer ignored

Own Id: OTP-10600

ssl:recv/3 could "loose" data when the timeout occurs. If the timout in ssl:connect or ssl:ssl_accept expired the ssl connection process was not terminated as it should, this due to gen_fsm:send_all_state_event timout is a client side time out. These timouts are now handled by the gen_fsm-procss instead.

Own Id: OTP-10569

Better termination handling that avoids hanging.

Own Id: OTP-10574

Sometimes the client process could receive an extra {error, closed} message after ssl:recv had returned {error, closed}.

ssl v3 alert number 41 (no_certificate_RESERVED) is now recognized

Experimental support for TLS 1.1 is now available, will be officially supported from OTP-R16. Thanks to Andreas Schultz for implementing the first version.

Experimental support for TLS 1.2 is now available, will be officially supported from OTP-R16. Thanks to Andreas Schultz for implementing the first version.

Own Id: OTP-8872

Removed some bottlenecks increasing the applications parallelism especially for the client side.

Own Id: OTP-10113

Workaround for handling certificates that wrongly encode X509countryname in utf-8 when the actual value is a valid ASCCI value of length 2. Such certificates are accepted by many browsers such as Chrome and Fierfox so for interoperability reasons we will too.

Robustness and improvement to distribution over SSL

Fix a bug where ssl_tls_dist_proxy would crash at caller timeout. Fix a bug where a timeout from the SSL layer would block the distribution indefinately. Run the proxy exclusively on the loopback interface. (Thanks to Paul Guyot)

Fix setup loop of SSL TLS dist proxy

Fix potential leak of processes waiting indefinately for data from closed sockets during socket setup phase. (Thanks to Paul Guyot)

Correct spelling of registered (Thanks to Richard Carlsson)

Own Id: OTP-9925

Added TLS PRF function to the SSL API for generation of additional key material from a TLS session. (Thanks to Andreas Schultz)

Own Id: OTP-10024

Invalidation handling of sessions could cause the time_stamp field in the session record to be set to undefined crashing the session clean up process. This did not affect the connections but would result in that the session table would grow.

Own Id: OTP-9696 Aux Id: seq11947

Changed code to use ets:foldl and throw instead of ets:next traversal, avoiding the need to explicitly call ets:safe_fixtable. It was possible to get a badarg-crash under special circumstances.

Own Id: OTP-9703 Aux Id: seq11947

Send ssl_closed notification to active ssl user when a tcp error occurs.

Own Id: OTP-9734 Aux Id: seq11946

If a passive receive was ongoing during a renegotiation the process evaluating ssl:recv could be left hanging for ever.

Own Id: OTP-9744

Support for the old ssl implementation is dropped and the code is removed.

Own Id: OTP-7048

The erlang distribution can now be run over the new ssl implementation. All options can currently not be set but it is enough to replace to old ssl implementation.

Own Id: OTP-7053

public_key, ssl and crypto now supports PKCS-8

Own Id: OTP-9312

Implements a CBC timing attack counter measure. Thanks to Andreas Schultz for providing the patch.

Own Id: OTP-9683

Mitigates an SSL/TLS Computational DoS attack by disallowing the client to renegotiate many times in a row in a short time interval, thanks to Tuncer Ayaz for alerting us about this.

Own Id: OTP-9739

Implements the 1/n-1 splitting countermeasure to the Rizzo Duong BEAST attack, affects SSL 3.0 and TLS 1.0. Thanks to Tuncer Ayaz for alerting us about this.

Own Id: OTP-9750

replace "a ssl" with "an ssl" reindent pkix_path_validation/3 Trivial documentation fixes (Thanks to Christian von Roques )

Own Id: OTP-9464

Adds function clause to avoid denial of service attack. Thanks to Vinod for reporting this vulnerability.

Own Id: OTP-9364

Error handling code now takes care of inet:getopts/2 and inets:setopts/2 crashes. Thanks to Richard Jones for reporting this.

Own Id: OTP-9382

Support explicit use of packet option httph and httph_bin

Own Id: OTP-9461

Decoding of hello extensions could fail to come to the correct conclusion due to an error in a binary match pattern. Thanks to Ben Murphy.

Own Id: OTP-9589

Calling gen_tcp:connect with option {ip, {127,0,0,1}} results in an exit with reason badarg. Neither SSL nor INETS This was not catched, resulting in crashes with incomprehensible reasons.

Fixed error in cache-handling fix from ssl-4.1.2

Own Id: OTP-9018 Aux Id: seq11739

Verification of a critical extended_key_usage-extension corrected

Own Id: OTP-9029 Aux Id: seq11541

The ssl application caches certificate files, it will now invalidate cache entries if the diskfile is changed.

Own Id: OTP-8965 Aux Id: seq11739

Now runs the terminate function before returning from the call made by ssl:close/1, as before the caller of ssl:close/1 could get problems with the reuseaddr option.

Own Id: OTP-8992

Correct handling of client certificate verify message When checking the client certificate verify message the server used the wrong algorithm identifier to determine the signing algorithm, causing a function clause error in the public_key application when the key-exchange algorithm and the public key algorithm of the client certificate happen to differ.

Own Id: OTP-8897

For testing purposes ssl now also support some anonymous cipher suites when explicitly configured to do so.

Own Id: OTP-8870

Sends an error alert instead of crashing if a crypto function for the selected cipher suite fails.

Own Id: OTP-8930 Aux Id: seq11720

Updated ssl to ignore CA certs that violate the asn1-spec for a certificate, and updated public key asn1 spec to handle inherited DSS-params.

Own Id: OTP-7884

Changed ssl implementation to retain backwards compatibility for old option {verify, 0} that shall be equivalent to {verify, verify_none}, also separate the cases unknown ca and selfsigned peer cert, and restored return value of deprecated function public_key:pem_to_der/1.

Own Id: OTP-8858

Changed the verify fun so that it differentiate between the peer certificate and CA certificates by using valid_peer or valid as the second argument to the verify fun. It may not always be trivial or even possible to know when the peer certificate is reached otherwise.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-8873

The server now verifies the client certificate verify message correctly, instead of causing a case-clause.

Own Id: OTP-8721

The client hello message now always include ALL available cipher suites (or those specified by the ciphers option). Previous implementation would filter them based on the client certificate key usage extension (such filtering only makes sense for the server certificate).

Own Id: OTP-8772

Fixed handling of the option {mode, list} that was broken for some packet types for instance line.

Own Id: OTP-8785

Empty packets were not delivered to the client.

Own Id: OTP-8790

Building in a source tree without prebuilt platform independent build results failed on the SSL examples when:

Own Id: OTP-8791

Fixed a handshake error which occurred on some ssl implementations.

Own Id: OTP-8793

Revise the public_key API - Cleaned up and documented the public_key API to make it useful for general use, also changed ssl to use the new API.

Own Id: OTP-8722

Added support for inputing certificates and keys directly in DER format these options will override the pem-file options if specified.

Own Id: OTP-8723

To gain interoperability ssl will not check for padding errors when using TLS 1.0. It is first in TLS 1.1 that checking the padding is an requirement.

Own Id: OTP-8740

Changed the semantics of the verify_fun option in the ssl-application so that it takes care of both application handling of path validation errors and verification of application specific extensions. This means that it is now possible for the server application in verify_peer mode to handle path validation errors. This change moved some functionality earlier in ssl to the public_key application.

Own Id: OTP-8770

Added the functionality so that the verification fun will be called when a certificate is considered valid by the path validation to allow access to each certificate in the path to the user application. Also try to verify subject-AltName, if unable to verify it let the application verify it.

Own Id: OTP-8825

New ssl now support client/server-certificates signed by dsa keys.

Own Id: OTP-8587

Ssl has now switched default implementation and removed deprecated certificate handling. All certificate handling is done by the public_key application.
