Bug #73307 [NEW]: Stream Socket Server unable to create IPv4/IPv6 Sockets

From: lucius at luciusgaitan dot com Operating system: CentOS 7.2.1511 x64 PHP version: 7.0.11 Package: Unknown/Other Function Bug Type: Bug Bug description:Stream Socket Server unable to create IPv4/IPv6 Sockets Description: ------------ Having a dual stack server, php is unable to create two sockets in the same port for different addresses ipv4 and ipv6. Only the first attempt to create the socket succeeds, the second returns "PHP Warning: stream_socket_server(): unable to connect to ... (Address already in use)". Using the defaults 0.0.0.0 and [::]. If the real ip addresses are defined everything works well. Also, $errno equals to 0 and returned value is FALSE as described in /manual/en/function.stream-socket-server.php. ./configure --with-config-file-path=/etc --disable-short-tags --enable-bcmath --enable-calendar --enable-gd-native-ttf --enable-mbstring --enable-pdo=shared --enable-sockets --enable-zip --with-curl=/opt/curlssl/ --with-freetype-dir=/usr --with-gd --with-jpeg-dir=/usr --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql=shared --with-pdo-sqlite=shared --with-pic --with-png-dir=/usr --with-zlib --with-zlib-dir=/usr --enable-pcntl --with-bz2 -enable-opcache --enable-fpm --with-fpm-systemd Thank you. Test script: --------------- $errno = null; $error = null; $bindto = ['0.0.0.0', '[::]']; $socket = []; for ($x = 0; $x < 2; ++$x) { $ctx = stream_context_create(['socket' => ['bindto' => $bindto[$x] . ':3672']]); $socket[] = stream_socket_server('tls://' . $bindto[$x] . ':3672', $errno, $error, STREAM_SERVER_BIND | STREAM_SERVER_LISTEN, $ctx); } -- Edit bug report at https://bugs.php.net/bug.php?id=73307&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73307&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73307&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73307&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73307&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73307&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73307&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73307&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73307&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73307&r=support Expected behavior: https://bugs.php.net/fix.php?id=73307&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73307&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73307&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73307&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73307&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73307&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73307&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73307&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73307&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73307&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73307&r=mysqlcfg
