2018-12-03erts: Allow code_model_small to be set in xcomp settingLukas Larsson
OTP-15473
2018-12-03erts: Implement delay_send using timer instead of pollLukas Larsson
The previous implementation uses a round-trip in the poll-set to simulate a yield of the port context. With the poll thread implementation this is no longer a good idea as it generated a lot more work for the system. So this commit changes the implementation to use a timer instead. OTP-15471
2018-12-03erts: Optimize driver_set_timer(0) to fire at onceLukas Larsson
By optimizing driver_set_timer for 0 we can use it instead of select to do a yield in the driver. Use full for delay_send in the inet driver. OTP-15472
2018-12-03erts: Optimize the inet driver multi timers for one timerLukas Larsson
The most common case for any socket is to have zero or one timer, so we optimize for the one case. The only case when we have more than one timer is when the multi accept feature is used.
2018-12-03erts: Move all inet tcp CONNECTED timers to multi timerLukas Larsson

2018-10-23erts: Make thr prgr wakeup current or sched 1Lukas Larsson
Before this change, it was always the aux thread that was woken to handle thread progress events scheduled to happen when all schedulers were going to sleep. This was ok in the pre-OTP-21 implementation when the aux thread just slept on a tse. Now that it sleeps in the fallback pollset this uses too much cpu so instead we wake the thread that is doing the request if it is a managed thread, or else we wake scheduler 1.
2018-10-23erts: Pass thread progress data where possibleLukas Larsson
The poll thread does a lot of waking up and then going back to sleep. A large part of the waking up is managing thread progress and a large part of that was using thread specific data to get the thread progress data pointer. With this refactor the tpd is passed to each of the functions which greatly decreases the number of ethr_get_tsd calls which in turn halves the CPU usage of the poller thread in certain scenarios.

2018-10-11erts: Fix UNC path handling on WindowsJohn Högberg
This is unlikely to be the last of the path problems seen after OTP 21, and I'm starting to regret my decision to unconditionally use long paths. The idea to hit all long-path problems all the time was good in theory as it makes such bugs far more visible, but there just aren't enough people who test pre-release versions on Windows, making this the world's slowest game of whack-a-mole.
2018-10-11ssl: TLS sender process needs to get updates of the socket option packetIngela Anderton Andin
If the socket option is set to {packet, 1|2|3|4} sender process needs to add a packet length header. If packet is changed with ssl:setopts/2 this needs to be communicated to tls_sender.

This would've been a bug if the value was used.
2018-10-10ssl: ERL-738 - Correct alert handling with new TLS sender processIngela Anderton Andin
With the new TLS sender process, solving ERL-622, TLS ALERTs sent in the connection state must be encrypted and sent by the TLS sender process. This to make sure that the correct encryption state is used to encode the ALERTS. Care must also be taken to ensure a graceful close down behavior both for normal shutdown and downgrading from TLS to TCP. The original TR ERL-738 is verified by cowboy tests, and close down behavior by our tests. However we alas have not been able to yet create a minimal test case for the originating problem. Also it seems it has become less likely that we run in to the TCP delivery problem, that is the guarantee is only on transport level, not application level. Keep work around function in ssl_test_lib but we can have better test as long as we do not get to much wobbling tests.

The macros for the BSD style option names had accidentally wound up outside the option parsing loop, causing unclear behaviour and Valgrind errors.
2018-09-28Fix rare bug in binary matching (again)Björn Gustavsson
2e40d8d1c51a attempted fix a bug in binary matching, but it only fixed the bug for the minimized test case. This commit removes the previous fix and fixes the bug in a more effective way. See the comments in the new code in `sys_core_bsm` for an explanation. This commit restores the optimizations in string.erl and dets_v9.erl that the previous fix disabled. I have not found any code where this commit will disable optimizations when they are actually safe. There are some changes to the code in ssl_cipher.erl in that some bs_start_match2 instruction did not reuse the binary register for the match context, but the delayed sub binary optimizations was never applied to the code in the first place. https://bugs.erlang.org/browse/ERL-689

The link should be between the connection process and the tls_sender process. But the start of the tls_sender process needs to be done by the process that also starts the connection process in order to correctly create the opaque #ssl_socket{}.
