2018-11-27[socket-nif] Conditional use of sctp struct fieldMicael Karlberg
Added config checks for the sctp struct field: sctp_event_subscribe.sctp_authentication_event Also, if-def'ed the code accordingly. If-def'ed code to handle the (non-) existence of IP_PMTUDISC_PROBE and IPV6_PMTUDISC_PROBE for the IP and IPv6 MTU_DISCOVER options. OTP-14831

* maint: Fix broken assertion on monitor release Avoid closing files in gc/monitor callbacks
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.
2018-11-06[socket-nif] Badly handled socket close for recvfrom and recvmsgMicael Karlberg
When type = dgram, the functions recvfrom and recvmsg did not properly handle socket close, cuaing the caller to hang indefinitely. OTP-14831
2018-11-05[socket-nif] Sending when buffer is full failedMicael Karlberg
When the send buffer was full (eagain), the send failed (with the rather useless return of {ok, -1}) instead of returning {error, eagain}. OTP-14831
2018-11-05[socket-nif] Make it possible to send (nif) debug to fileMicael Karlberg
Make it possible to open a file and send debug printouts to (instead of stdout) for debug printouts from the nif-code. OTP-14831
2018-11-02[socket-nif] Inherit buffer sizes when acceptingMicael Karlberg
An "accepted" socket will inherit the parent (listen) socket's buffer sizes (rBufSz, rCtrlSz and wCtrlSz). OTP-14831
2018-11-01[sock-nif|test] Add a ping-pong test caseMicael Karlberg
We got some kind of send hang...
2018-10-30[socket-nif] Add a send and receive chunks test caseMicael Karlberg
The send and recv test case triggered a two bugs. One was that there was no re-selecting when only a portion of the data was received (which meant that we stopped reading). Also, the wrong 'current' (writer) was reset when demonitor current reader after a successful read (which meant that future readers would never have been monitored). OTP-14831
2018-10-22[socket-nif] Initiation of "current reader" missing for recvfromMicael Karlberg
When calling the recvfrom function when there is no data, we should be made wait (for the specified amount of time). But this did not work because the "current reader" structure was not initiated. OTP-14831
2018-10-18[socket-nif] setopt and getopt with level ipv6Micael Karlberg
The level argument for IPv6 can be either SOL_IPV6 or IPPROTO_IPV6, whichever is defined. But it was hard- coded to SOL_IPV6, which is not defined on FreeBSD. OTP-14831

2018-10-18[socket-nif] Initiation of "current reader" missing for recvmsgMicael Karlberg
When calling the recvmsg function when there is no data, we should be wait (for the specified amount of time). But this not not wotk because the "current reader" structure was not initiated. OTP-14831
2018-10-18[socket-nif] Socket closeMicael Karlberg
Fixed a number of issues regarding monitor handling. Monitors are now wrapped in its own type (ESockMonitor). This is hopefully temporary! The reason for this is that there is no way to "initialize" a monitor after a demonitor. This could mean that after a successful demonitor, you could still get a down-callback, and thenh compare with, for instance, ctrlMOn field and get a match, even though it was just (successfully) demonitor'ed. To make debugging easier, the monitor and demonitor calls are now wrapped in their own functions, with debug printouts before and in case of failure, also after the actual calls Also, fixed a number of problems with cancel, where monitors where left still active after cleaning up current and active reader, writer and acceptor. OTP-14831
2018-10-16[socket-nif] Recv handling of closing socketsMicael Karlberg
Fixed more issues regarding closing sockets. Specifically with respect to recv calls. Also, added demonitor for all *current* processes. Also fixed a buffer overflow problem when writing an warning message (the timestamp buffer was not large enough). OTP-14831
2018-10-15[socket-nif] Fix socket close when owner process exitsMicael Karlberg
The handling of terminating controlling-process was incomplete. Also added state check (CLOSED and CLOSING) in all nif-functions to prevent access for a closed (or closing) socket. OTP-14831

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.
2018-10-11erts: Fix a compiler warningJohn Högberg
This would've been a bug if the value was used.
2018-10-09[socket-nif] The supports function now also handles sctp and ipv6Micael Karlberg
The supports function now also handles testing for SCTP and IPv6 support. Basic test at the moment, but better then nothing. OTP-14831
2018-10-09[socket-nif] Completed (ahum) the socket option(s) part of supportsMicael Karlberg
"Completed" the socket options part of the supports function. OTP-14831

2018-10-04[socket-nif] Add owner validation when setopt controlling_processMicael Karlberg
Before allowing setopt(Sock, opt, controlling_process, NewPid), verify that the caller is actually the current controlling_process. OTP-14831
2018-10-04[socket-nif] Fixed decode of send and recv flagsMicael Karlberg
Add explicitly handling the default case, when not flags are provided (value of zero). OTP-14831
2018-10-04[socket-nif] Socket option 'SO_DOMAIN' not avalable on all platformsMicael Karlberg
Internally in the socket module we accessed domain, type and protocol for an open socket. But as it turns out, domain (family) is not actually available as a socket option on all platforms. FreeBSD in this case. So, since we store these values in the socket descriptor anyway, we switch to use these values for our internal use instead. OTP-14831
2018-09-28[socket-nif] Add support for socket (level otp) buffer optionsMicael Karlberg
Add support for otp level socket options rcvbuf, rcvctrlbuf and sndctrlbuf. These options define default sizes for these buffers. The 'rcvbuf' is used when receiving messages when calling the recv, recvfrom and recvmsg functions. The 'rcvctrlbuf' is used for the control message header info when calling the recvmsg function. The 'sndctrlbuf' is used for the control message header info when calling the sendmsg function. OTP-14831
2018-09-27[socket-nif] Improve socket stopMicael Karlberg
Make sure the current whatever (writer, reader or writer) is not the closer pid before *attempting* to sending the abort message. And if that fails, issue a warning message (not aborting). OTP-14831
2018-09-27[socket-nif] Add proper recv timeout handlingMicael Karlberg
Added proper recv timeout handling. Made use of the enif_select(mode = cancel) feature. Each time a timeout expires, the "active" recv (the surrent reader select) has to be cancelled. Not yet tested...something for the new test suite... Also, added support for getopt(controlling_pprocess) that, for some reason, was not yet implemented. OTP-14831

It's impossible to call NIF with wrong argc from Erlang and thus pointless to throw badarg.

bmk/20180918/nififying_inet/OTP-14831 Also needed to "revert" two of the chnages, related to assoc id. This is in FreeBSD defined as an uint32 but on linux as a int32.

2018-09-20[socket-nif] Add proper send timeout handlingMicael Karlberg
Added proper send timeout handling. Made use of the enif_select(mode = cancel) feature. Each time a timeout expires, the "active" send (the surrent write select) has to be cancelled. OTP-14831
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
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
