* john/erts/assert-dirty-aux-work: Abort when aux work runs on a dirty scheduler
2018-11-28erts: Fix unexpected inet_reply message from failing file:sendfileSverker Eriksson
A failing file:sendfile call would often send a message {inet_reply, Port, {error, Reason}} that would pollute the mailbox of the calling process. TCP_REQ_SENDFILE has its own reply messages format {sendfile, _, _} and does not expect an inet_reply message. Solution: Suppress inet_reply error message if TCP_ADDF_SENDFILE is set.
2018-11-28erts: Fix bug in sendfile for active socketSverker Eriksson
driver_select() was called after port had been killed by tcp_inet_sendfile() calling tcp_send_error().

2018-11-27Abort when aux work runs on a dirty schedulerJohn Högberg
While the system will keep working, the aux work will never run and the affected scheduler never goes to sleep. OTP-15446 is a good example of this. As this error easily flies under the radar it's best to make it immediately visible. The assertions we had in debug builds were clearly not enough to catch all sources of this problem.

erts: fix attempt to start timer when executing on dirty scheduler OTP-15446
2018-11-26erts: fix attempt to start timer when executing on dirty schedulerMaxim Fedorov
Since OTP R20, there is a possibility for MAJOR garbage collection to run on dirty scheduler. So DistEntry destructor is being called on dirty scheduler as well. This, in turn, leads to an attempt to schedule timer on a dirty scheduler too, which is impossible (and will assert on debug build, but does succeed for release build, creating an infinite busy loop, since aux work wakes scheduler up, but dirty scheduler cannot execute aus work). There is a similar method in erl_hl_timer, see erts_start_timer_callback.

We only do this when the user has explicitly told us it's okay to partially disable mitigation (spectre-mitigation=incomplete). The macro is inert if it isn't.

2018-11-13Fix broken assertion on monitor releaseJohn Högberg
We sometimes bump the refc without messing with the table, which means that we sometimes decrement it while in the table, causing the old assertion to fail. The property we want to check is that neither end of the monitor is present in the table when the monitor is deleted.
2018-11-13Avoid closing files in gc/monitor callbacksJohn Högberg
Closing files in these callbacks could block scheduler progress and cause major system instability. We now defer these operations to a dedicated process instead. This process may in turn block forever and prevent further orphaned files from being closed, but it will keep the emulator itself from misbehaving.
