2018-09-20beam_ssa_recv: Remove redundant {var, _} wrappingJohn Högberg
Now that variables are represented as #b_var{}, there's no longer any risk of colliding with anything else.
2018-09-20Consistently use #b_var{} instead of var_name()John Högberg
We chose to refer to variables through their var_name() because we anticipated the need to annotate them, but it turned out we didn't really need that, and many things become a lot cleaner if the entire #b_var{} is used to represent variables.

* ingela/ERL-622/fix: ssl: Move link to correct process
2018-09-20ssl: Move link to correct processIngela Anderton Andin
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{}.
2018-09-19[socket-nif] Add proper connect and accept timeout handlingMicael Karlberg
Added proper connect and accept timeout handling. Made use of the enif_select(mode = cancel) feature. Each time a timeout expires, the previous operation (connect or accept) has to be cancelled (actually its the select operation that has to be cancelled). Only partial implementation of cancel for now (connect and accept). More to follow... OTP-14831

OTP-14461 - New 'rand' algorithm: Xoroshiro928** also for 'crypto' Implement a new 'rand' algorithm named 'exro928ss' and a new 'crypto' plugin for 'rand' named 'crypto_aes'. Both are based on Xoroshiro928** which is derived from Xoroshiro1024** modified to use 58-bit words for performance reasons in the Erlang VM. Xoroshiro1024** has got the Xoroshiro1024 generator and the StarStar scrambler from the 2018 paper "Scrambled Linear Pseudorandom Number Generators" by David Blackman and Sebastiano Vigna. This generator and scrambler combination shows no systematic weaknesses in standard statistical tests as TestU01(BigCrush) and PractRand, unlike the previously used * and + scramblers in the 'rand' module that exhibit statistical weaknesses for the lowest bits. The 'crypto' plugin uses AES-256 as scrambler and the Xoroshiro928 as generator, which gives the same very long period and jump functions as for Xoroshiro928**, but a cryptographically secure scrambler gives absolutely no detectable statistical weaknesses regardless of how the generated numbers are used. The speed of 'exro928ss' is only about 30-50% slower than the default fast 'rand' algorithm, but the state is roughly the double and it produces about 8 times the garbage per iteration. The speed of 'crypto_aes' is about half (amortized) that of the default fast 'rand' algorithm which is fast and thanks to doing encryption in batches caching the result. Hence the state is much larger.

2018-09-18[socket-nif] Added (more) tests for [recv|send]msgMicael Karlberg
Added some more tests for sendmsg (with cmsghdr). OTP-14831
2018-09-18[socket-nif] Cleanup and guardsMicael Karlberg
Some cleanup and also added a guard to sendmsg to ensure that only ctrl (cmsg hdr) with actual content will be "sent down". OTP-14831
2018-09-18[socket-nif] Encoding of cmsg headers for sendmsgMicael Karlberg
Fixed various issues with regard to encode of CMsgHdrs during sendmsg. OTP-14831
2018-09-18[socket-nif] CMsgHdr and various doc related changesMicael Karlberg
Updated the (send) cmsghdr type and the handling of it (in the nif code). Still not tested! Removed the is_loaded nif function. Tried to get fix the doc build problem (socket.erl *i think*), which causes socket.html generation to fail with: "cannot find module exporting type" To solve this I tried to run dialyzer on preloaded, and ran into problems with enc_setopt_value. Update various specs and types to "solve" this (which did not work). Updated the nif-stub functions to make dialyzer happy.
2018-09-18[socket-nif] Add support for (recvmsg) control message ipv6_pktinfoMicael Karlberg
Added support for (recvmsg) control message ipv6_pktinfo, for level = ipv6 and type = pktinfo. This is enabled by setting the socket option: recvpktinfo for level ipv6. Not yet tested! OTP-14831
2018-09-18[socket-nif] Add more data types (with doc) and (C) debugMicael Karlberg
Add more debug printouts for the new sendmsg. Also added new (erlang) types with doc. OTP-14831
2018-09-18[socket-nif] Add preliminary support for sendmsgMicael Karlberg
Added function sendmsg/2,3,4. Actually worked on the first try. Something must be wrong... Still no supported cmsghdr's (only support headers where the data part is already a binary, which therefor does not require any processing). So if the cmsghdrs actually work is unclear. OTP-14831
2018-09-18[socket-nif] Processing of more cmsg headersMicael Karlberg
Added processing or more cmsg headers (for more options). Now (also) supports: socket:timestamp. Also various fixes and cleanups. For some reason calling getopt(Sock, 0, {13, int}) (or similar) fails with badarg even though the nif-function (nif_getopt) actually returns a valid value (for instance: {ok, 0}). OTP-14831
2018-09-18[socket-nif] Add more control message decodingMicael Karlberg
Added decoding of the "known" control message options: pktinfo, recvtos, recvttl and recvorigdstaddr). OTP-14831
2018-09-18[socket-nif] Debugged and stuffMicael Karlberg
It seems to work, with atleast some of the cmsg options. More testing needed... OTP-14831
2018-09-18[socket-nif] Add support for recvmsgMicael Karlberg
Added preliminary support for function recvmsg. At the moment this only works on *nix (Windows has another function, WSARecvMsg, which has a slightly different API). Also we have "no" cmsg decode at the moment (just level and type). OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option sendsrcaddrMicael Karlberg
Added support for ip level socket option SENDSRCADDR. This option requires sendmsg to actually use, so we cannot test this fully at the moment. OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option recvorigdstaddrMicael Karlberg
Added support for ip level socket option RECVORIGDSTADDR. This option requires recvmsg to actually use, so we cannot test this fully at the moment (although both set and get works). OTP-14831
2018-09-18[socket-nif] Updated socket typeMicael Karlberg
Updated the socket type. No longer store "stuff" that can be retrieved by other means (domain, type and protocol). OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option retoptsMicael Karlberg
Added support for ip level socket option RETOPTS. OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option transparentMicael Karlberg
Added support for ip level socket option TRANSPARENT. OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option pktinfoMicael Karlberg
Added support for ip level socket option PKTINFO. This option requires sendmsg and/or recvmsg to actually use, so we cannot test this fully at the moment (although both set and get works). OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option hdrinclMicael Karlberg
Added support for ip level socket option HDRINCL. As this option is raw only, it has not yet been tested! OTP-14831
2018-09-18[socket-nif] Add support for socket (level ip) option msfilterMicael Karlberg
Added support for ip level socket option MSFILTER. This option has not been tested *in any way*... OTP-14831
2018-09-18[socket-nif] Add support for socket (level ipv6) option recverrMicael Karlberg
Added support for the IPv6 socket option RECVERR. To actually make use of this option, we need the recvmsg function, which we don't have yet. Baby steps. OTP-14831.
2018-09-18[socket-nif] Add support for socket (level ip) option recverrMicael Karlberg
Added support for the IP socket option RECVERR. To actually make use of this option, we need the recvmsg function, which we don't have yet. Baby steps. OTP-14831.
2018-09-18[socket-nif] Add support for socket (level ipv6) option addrformMicael Karlberg
Added support for the IPv6 socket option ADDRFORM. Only allowed for IPv6 sockets that are connected and bound to a v4-mapped-on-v6 address. OTP-14831.
