#32324 [NEW]: socket_recvfrom stops reading at null char

From: admin at freeworldonline dot com Operating system: Linux stripples.devel.redhat.com PHP version: 4.3.10 PHP Bug Type: Unknown/Other Function Bug description: socket_recvfrom stops reading at null char Description: ------------ I am trying to recieve data via a UDP socket using the socket_recvfrom function. It works fine unless there is a null char anywhere in the packet. If there is the buffer returned only contains data up to that point, although the value returned by the function shows there is actually more data. Reproduce code: --------------- if (!$sock=socket_create(AF_INET,SOCK_DGRAM,SOL_UDP)) { echo "<b>Error:</b> Failed to create socket, ".socket_strerror(socket_last_error($sock))."<br>\n"; } elseif (!socket_bind($sock,"0.0.0.0",41330)) { echo "<b>Error:</b> Failed to bind socket, ".socket_strerror(socket_last_error($sock))."<br>\n"; socket_close($sock); } else { echo "<b>Ready, please send a message to port 41330 using UDP</b><br><br>\n"; $size=socket_recvfrom($sock,$buf,65535,0,$clientIP,$clientPort); if ($buf===FALSE) { echo "<b>Error:</b> Returned false, ".socket_strerror(socket_last_error($sock))."<br>\n"; } else { echo "Message from ".$clientIP.":".$clientPort." (".strlen($buf)."/".$size." bytes)...<br>\n"; } socket_close($sock); } Expected result: ---------------- All data to be placed into the buffer regardless of any null characters in the packet. Actual result: -------------- If you send a datagram to port 41330 while this is running with a null character mid way into the packet, any data from there onwards will not be placed into $buf. -- Edit bug report at http://bugs.php.net/?id=32324&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32324&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32324&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32324&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32324&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32324&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32324&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32324&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32324&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32324&r=support Expected behavior: http://bugs.php.net/fix.php?id=32324&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32324&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32324&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32324&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32324&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32324&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32324&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32324&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32324&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32324&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32324&r=mysqlcfg
