2018-10-19Fix hanging gen_tcp send vs close raceRaimo Niskanen
While a gen_tcp send was in progress with filled buffers and slow receiver a close (from another process) would place the port in a half dead state so the port could not signal back to send, that waited for confirmation. The solution is to after some time (5 s) of waiting for send confirmation set a monitor on the port, which detects if the port becomes half dead due to close from another process. The close pending loop has also been improved to use the linger timeout for waiting, and to set a system timeout (arbitrarily selected 3 min) to not wait forever when the other end reads data s l o w l y (tarpitting, kind of).

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.

This would've been a bug if the value was used.
2018-10-11Add nopush TCP socket optionIgor Slepchin
This translates to TCP_CORK on Linux and TCP_NOPUSH on BSD. In effect, this acts as super-Nagle: no partial TCP segments are sent out until this option is turned off. Once turned off, all accumulated unsent data is sent out immediately. The latter is *not* the case on OSX, hence the implementation ignores "nopush" on OSX to reduce confusion.

2018-10-02Implement {netns,NS} option for inet:getifaddrs/1Raimo Niskanen
Also implement the same option for the legacy undocumented functions inet:getif/1,getiflist/1,ifget/2,ifset/2. The arity 1 functions had before this change got signatures that took a socket port that was used to do the needed syscall, so now the signature was extended to also take an option list with the only supported option {netns,Namespace}. The Socket argument variant remains unsupported. For inet:getifaddrs/1 the documentation file was changed to old style function name definition so be able to hide the Socket argument variant that is visible in the type spec. The arity 2 functions had got an option list as second argument. This list had to be partitioned into one list for the namespace option(s) and the other for the rest. The namespace option list was then fed to the already existing namespace support for socket opening, which places the socket in a namespace and hence made all these functions that in inet_drv.c used getsockopt() work without change. The functions that used getifaddrs() in inet_drv.c had to be changed in inet_drv.c to swap namespaces around the getifaddrs() syscall. This functionality was separated into a new function call_getifaddrs().
