2016-06-01Rewrite inet_drv for AF_LOCALRaimo Niskanen
2016-01-12Assign externally open fd to gen_tcp (UDS support)Serge Aleynikov
When a AF_LOCAL file descriptor is created externally (e.g. Unix Domain Socket) and passed to `gen_tcp:listen(0, [{fd, FD}])`, the implementation incorrectly assigned the address family to be equal to `inet`, which in the inet_drv driver translated to AF_INET instead of AF_LOCAL (or AF_UNIX), and an `einval` error code was returned. This patch fixes this problem such that the file descriptors of the `local` address family are supported in the inet:fdopen/5, gen_tcp:connect/3, gen_tcp:listen/2, gen_udp:open/2 calls

2015-10-05Avoid always updating inet_dns in the primary bootstrapBjörn Gustavsson
The include file inet_dns_record_adts.hrl is generated by the Perl script inet_dns_record_adts.pl in a non-deterministic way. That is, every time the script is run, the functions will be in a different order. That will cause inet_dns.beam in the primary bootstrap to be updated every time the bootstrap is updated, even though there is no actual code change. Modify the Perl script to sort the keys pulled out from hashes to make the order deterministic.

2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

2015-05-22Fix parsing of IPv6 addresses to limit leading zerosRory Byrne
The current implementations of inet:parse_ipv6_address/1 and inet:parse_ipv6strict_address/1 permit address strings which have an unlimited number of leading zeros. Addresses such as: "0000000000000000000000000000000ffff::" "::00000000000000000000000000000000000000000000000000000000" "::0000000f435:1" If we are using this facility to validate string representations of IPv6 addresses, then we would end up validating addresses which are non-conformant (with respect to RFC 4291 section 2.2) and potentially dangerous. This patch ensures that each segment of an IPv6 address has a maximum of 4 hex digits.

* bjorn/kernel/code-loading: kernel application: Start code server first code: Reduce overhead of native code checking for loaded modules
2015-05-06kernel application: Start code server firstBjörn Gustavsson
When the code server has started, it will read the .beam files for all loaded modules to see whether they contain native code that should be loaded. To make that as fast as possible when we have no native code, start the code server as early as possible to minimize the number .beam files that must be read from disk. The code server does not use the 'file' module, so it is OK to start the code server before starting the file_server process. On my computer, the time for checking the loaded modules for native code is reduced from roughly 2 ms to 1.5 ms.
2015-05-06code: Reduce overhead of native code checking for loaded modulesBjörn Gustavsson
When the code server has been started, the function load_native_code_for_all_loaded/0 will check whether the .beam files for all loaded modules contain any native code. If there is native code, it will be loaded. If there is no native code, on my computer the check will take about 10 ms. That time can be reduced to about 2 ms if we replace the call to code beam_lib:chunks/2 with a call to prim_file:read_file/1 to read the file and a call to code:get_chunk/2 to check whether the chunk for native code is present. Furthermore, the entire check can be spawned off to a separate process and done in parallel with OTP starting up.

2015-05-02kernel: inet6_tcp_dist: reuse inet_tcp_dist codeDanil Zagoskin
inet6_tcp_dist module is an old copy of inet_tcp_dist with changed address family. New features (such as listening port range, interface and generic options) are implemented in inet_tcp_dist only, inet6_tcp_dist looks abandoned (it does not even have tests). This patch makes inet_tcp_dist internals work with abstract driver, and inet6_tcp_dist becomes just a thin wrapper for it.
