2018-08-03erts: Fix seq_trace to not clear token for system messagesLukas Larsson
A lot of erts internal messages used behind APIs to create non-blocking calls, e.g. port_command, would cause the seq_trace token to be cleared from the caller when it should not. This commit fixes that and adds asserts that makes sure that all messages sent have to correct token set. Fixes: ERL-602

2018-07-30erts: Limit the automatic max buffer for UDP to 2^16Lukas Larsson
There is no reason to have a larger buffer than this as the recvmsg call will never return more data. OTP-15206
2018-07-30erts: Handle EMFILE errors in forker_driver for writeLukas Larsson
Before this change, if a write to the uds failed due to EMFILE to ETOOMANYREFS the entire vm would crash. This change makes it so that an SIGCHLD is simulated to that the error is propagated to the user instead of terminating the VM.

which only existed in a patched version of valgrind (by pan) no longer used. Instead we use standard VALGRIND_PRINTF which will end up like this if valgrind log format is XML and valgrind version >= 3.9: <clientmsg> <tid>7</tid> <threadname>3_scheduler</threadname> <text>Test case #20 ei_encode_SUITE:test_ei_encode_long/1 </text> </clientmsg> Note the extra trailing whitespace that may occure before </text>.

2018-07-16erts: Free udp buffer when getting EAGAINLukas Larsson
Only SCPT should keep the recv buffer when going into select. If UDP does it, it will result in many more memory allocations than there should be which can be very detrimental to performance.

2018-07-13Fix a rare crash when matching on literal mapsJohn Högberg
When matching on a literal map, the map is placed into the general scratch register first. This is fine in isolation, but when the key to be matched was in a Y register it would also be placed in the scratch register, overwriting the map and crashing the emulator.

2018-07-12erts: Fix bug in crash dump generationSverker Eriksson
Symptom: emulator core dumps during crash dump generation. Problem: erts_dump_lit_areas did not grow correctly to always be equal or larger than number of loaded modules. The comment about twice the size to include both curr and old did not seem right. The beam_ranges structure contains *all* loaded module instances until they are removed when purged.

2018-07-03Use fallback pollset for stdin and friends when using kqueueJohn Högberg
This is a hack to make the "noshell" option work; kqueue can poll these fds but will not report EV_EOF. This may be common to all all pipes but we have no way to tell whether an fd is a pipe or not.
