2016-11-02Add ECC curve selection order config in TLS serverFred Hebert
As per RFC 4492 Sec 5.1, the preferred order of selection of named curves is based on client preferences. Currently, the SSL application only picks entries according to the absolute order of entries as tracked in a hardcoded list in code. This patch changes things so that the client-specified order is preferred. It also allows a mode where the server can be configured to override the client's preferred order with its own, although the chosen ECC must still be within both lists. The configuration is done through the following options: - `eccs`, shared by clients and servers alike, allows the specification of the supported named curves, in their preferred order, and may eventually support more values for explicit primes and so on. - `honor_ecc_order`, a server-only option, is similar to `honor_cipher_order` and will, by default let the server pick the client-preferred ECC, and otherwise pick the server-preferred one. The default value for `eccs` is the same as before, although the server-chosen ECC now defaults to the client rather than previous choice. A function `ssl:eccs()` has been added that returns the highest supported ECCs for the library.

2016-10-31kernel: Add lost dependency to erts-8.1Sverker Eriksson
In OTP-19.1 (c70ca686fe269db6079a2ca1c7e09cdfc0cfa903) erts_code_purger:finish_after_on_load/2 was added and called by code_server.erl.
2016-10-31Propagate exceptions fully when using proc_libLoïc Hoguin
This makes proc_lib behaves like a normal process as far as the propagation of exceptions is concerned. Before this commit, the following difference could be observed: 6> spawn_link(fun() -> ssl:send(a,b) end). <0.43.0> 7> flush(). Shell got {'EXIT',<0.43.0>, {function_clause, [{ssl,send,[a,b],[{file,"..."},{line,275}]}]}} ok 8> proc_lib:spawn_link(fun() -> ssl:send(a,b) end). <0.46.0> 9> flush(). Shell got {'EXIT',<0.46.0>,function_clause} After this commit, we get the following instead: 3> flush(). Shell got {'EXIT',<0.61.0>, {function_clause, [{ssl,send,[a,b],[{file,"..."},{line,275}]}, {proc_lib,init_p,3,[{file,"..."},{line,232}]}]}} The stacktrace will show minor differences of course but the form is now the same as without proc_lib. The rationale behind this commit is that: * We now have a single form regardless of how the process was started * We can use the stacktrace to programmatically alter behavior (for example an HTTP server identifying problems in input decoding to send back a generic 400, or a 500 otherwise) * We can access the stacktrace to print it somewhere (for example an HTTP server could send it back to the client when a debug mode is enabled)

2016-10-29Make a separate application module for MnesiaRichard Carlsson
To separate concerns and reduce confusion, avoid implementing two behaviours in a single module. Make a single start_link() helper in mnesia_sup and remove the unused mnesia_sup:start() utility function.

2016-10-27controlling_process can return {error, badarg}Péter Gömöri
For gen_tcp, gen_udp and gen_sctp controlling_process/2 can return badarg if erlang:port_connect/2 fails with badarg. This can easily happen if the new owner is not alive but in some race condition also when the socket is closed right before port_connect/2 (and after the previous socket function) This commit documents this behaviour.

The testcases shell_unicode_string and shell_no_unicode in ssh_basic_SUITE could raise an exception in the end_per_suite when stopping the dameon. This is due to a natural race condition between the server and the client.

2016-10-27ssh: Reduce the renegotiation limit in test with OpenSSH clientHans Nilsson
in ssh_to_openssh_SUITE:erlang_server_openssh_client_renegotiate/1 The reason is that it seems that on some small machines we get an out-of-memory exception if the limit is to high. This is probably because a chunk of data larger than the limit is piped from a file into the OpenSSH runing in a shell in a port.
2016-10-27Don't copy funs into guardsBjörn Gustavsson
Funs must not be created in guards. The instruction for creating a fun clobbers all X registers, which is a bad thing to do in a guard.
