2016-02-22ssl: Newer cipher suites now presented correctlyIngela Anderton Andin
Older SSL/TLS versions have cipher suites that look like {key_exchange(), cipher(), MAC::hash()} and the hash function used by the PRF (Pseudo Random function) is implicit and always the same for that protocol version. In TLS 1.2 a cipher suite is {key_exchange(), cipher(), MAC::hash(), PRF::hash()}. Internally a cipher suite is always a four tuple but for backwards compatibility older cipher suites will be presented as a three tuples, however new cipher suites should be presented as four tuples.

2016-02-22ssl: Include options form connect/listen/accept in connection_information/[1,2]Ingela Anderton Andin
Make sure that options only relevant for one role (client|server) is set to undefined when the other role is invoked. As there are many options to ssl, and many are optional, we choose to filter out all undefined options to avoid overwhelming the user with not relevant information. This way there is no need for any special handling of the role specific options which is also nice.

2016-02-09mnesia: let loader check if tablelock is neededDan Gudmundsson
move_table_copy needs the lock that was set previously in del_table_copy. This doesn't work on old nodes, so bump protocol version and check it. Remove old protocol conversion code, which have been around since OTP-R15. Checking if lock is needed requires rpc communication via mnesia_gvar ets table to be backwards compatible.

2016-02-08ssl: verify cert signature against original cert binaryMatt Campbell
When searching for a certificate's issuer in the `CertDB`, verify the signature against the original DER certificate from the handshake instead of a re-encoding of the parsed certificate. This avoids false negatives due to differences between DER encoding implementations of OTP and other platforms.

2016-02-08Eliminate crash because of unsafe delaying of sub-binary creationBjörn Gustavsson
The following code would fail to compile: decode(<<Code/integer, Bin/binary>>) -> <<C1/integer, B1/binary>> = Bin, case C1 of X when X =:= 1 orelse X =:= 2 -> Bin2 = <<>>; _ -> Bin2 = B1 end, case Code of 1 -> decode(Bin2); _ -> Bin2 end. The error message would be: t: function decode/1+28: Internal consistency check failed - please report this bug. Instruction: return Error: {match_context,{x,0}}: The beam_bsm pass would delay the creation of a sub-binary when it was unsafe to do so. The culprit was the btb_follow_branch/3 function that for performance reasons cached labels that had already been checked. The problem was the safety of a label also depends on the contents of the registers. Therefore, the key for caching needs to be both the label and the register contents. Reported-by: José Valim

2016-02-05mnesia: Avoid deadlock possibility in mnesia:del_table_copy schemaDan Gudmundsson
del_table_copy grabs a write lock in a new process in prepare_op/3 to change 'where_to_read' when a table copy is updated. When del_table_copy(schema, Node) is called all copies located on Node are deleted, and thus many locks are taken. Since this was done outside of the schema-transaction, mnesia's deadlock prevention algorithms was sidestepped and a deadlock could occur. Fix by always grabbing write-locks for all changed tabs early and in the same transaction, this might slow done the operation some but it must be done and it also cleans up the code.

2016-02-03Speed up supervisor:count_children/1; simple_one_for_oneRory Byrne
Speed up supervisor:count_children/1 for simple_one_for_one supervisors. This is achieved by avoiding looping through all the child process and verifying that each one is alive. For a supervisor with 100,000 'temporary' children the count-time will drop from approx 25ms to about 0.005ms. For a supervisor with 100,000 'permanent' or 'transient' children the count-time will drop from approx 30ms to about 0.005ms. This avoids having the supervisor block for an extended period while the count takes place. Under normal circumstances the accuracy of the result should also improve since the duration is too short for many processes to die during the count.
2016-02-03Add supervisor:get_callback_module/1Siri Hansen
This function is used by release_handler during upgrade. This was earlier implemented in the release_handler, but it required a copy og the definition of the supervisor's internal state, which caused problems when this state was updated.

2016-02-03tools: Fix wrong instrumentation of binary comprehensionsLuis Rascao
When cover instruments binary comprehensions it's generating a {block, ...} abstract code term inside a {bc, ...} term that is causing the evaluation to fail at runtime. Removing the block statement eliminates the error. The template of a bit string comprehension cannot have a counter since it is not allowed to be a block.
