#27509 [Fbk->Opn]: fsockopen() failed with "Addr family not supported by protocol" error

ID: 27509 User updated by: scott at abcoa dot com Reported By: scott at abcoa dot com -Status: Feedback +Status: Open Bug Type: Sockets related Operating System: AIX 4.3.3 PHP Version: 4.3.4 New Comment: With the latest CVS tarball and the configure line, "./configure --disable-ipv6". After configuring and before the make compilation. The main/php_config.h showed ... --snip-- /* Whether to enable IPv6 support */ /* #undef HAVE_IPV6 */ --snip-- So far, so good. Again, checking for ... --snip-- /* Define if you have the getaddrinfo function */ #define HAVE_GETADDRINFO 1 --snip-- So, it is already defined as you expected. So, replacing it with "/* #define HAVE_GETADDRINFO 1 */". Then on to make and installing. So far, so good. Then ran the fsockopen() test.. The result look good.. --snip-- Content-type: text/html X-Powered-By: PHP/4.3.5RC4-dev !#/usr/local/bin/php 0 --snip-- Then tested with the "Example 1. fsockopen() Example" from http://us3.php.net/manual/en/function.fsockopen.php and it work like a charm. Let me know when the fix is made and get checked into the CVS for 4.3.4 build/branch and for 5.0 build/branch. I'll be happy to do a few more testing if you need me to. Previous Comments: ------------------------------------------------------------------------ [2004-03-11 15:40:28] pollita@php.net That's..... I think "messed up" is the technical term. I see two major problems here. 1) hints.ai_family is being reset by code that should be excluded by having used the --disable-ipv6 switch. 2) getaddrinfo() is returning a structure that, while it contains a top-level field insisting it's an AF_INET address. Contains a sockaddr child structure with an ai_family of PF_UNSPEC. So when php_hostconenect gets it, it tries creating a socket with an "unspecified" address family. No wonder it's unsupported eh? Let's go down this road: First, undo that patch, download a new tarball if necessary. Heck, might as well grab the latest CVS snapshot. Though if you reuse your current tree with a restored main/network.c you'll need to be sure and run make clean. Next, run a normal ./configure with the --disable-ipv6 switch. Now, BEFORE running make, edit main/php_config.h and check that HAVE_IPV6 is in fact, not defined. If it is defined, comment it out (And let us know in your feedback). Next, look for HAVE_GETADDRINFO in the same file. Make sure it is also undefined. (I expect that it will be defined, so you'll need to comment it out) Finally, run make, and try out the fsockopen test. ------------------------------------------------------------------------ [2004-03-11 13:55:26] scott at abcoa dot com Here's the response I got... It's also the same with the host, "www.example.com" instead of "www.google.com". --snip-- Content-type: text/html X-Powered-By: PHP/4.3.5RC4-dev !#/usr/local/bin/php getaddresses GETADDRINFO method defaulting to AF_INET(2) hints.ai_family = 0 got result sai->ai_family = 2 returning from getaddresses: n = 1 php_network_getaddresses returned 1 Creating socket of type 0 (AF_INET = 2) socket() returned: -1 <br /> <b>Warning</b>: fsockopen(): unable to connect to www.google.com:80 in <b>/home/website/emarket/test_fsockopen_shell.sh</b> on line <b>6</b><br /> 66 Addr family not supported by protocol --snip-- ------------------------------------------------------------------------ [2004-03-11 13:12:03] pollita@php.net Sorry, I wanted you to run a test with fsockopen(), not the socket_* extension. (Believe it or not they're completely different implementations even though they do the same thing) <?php $fp = fsockopen('www.exmaple.com', 80); ?> Please run that one against the version you've already patched and compiled. ------------------------------------------------------------------------ [2004-03-11 10:54:40] scott at abcoa dot com Not a problem! Been wanting the fsockopen() to work, so my company's website can function once again. Applied the patch and went through the programmer's ritual (compiling) all over again. Out came the result, believe it or not, it's the same end result. --snip-- Content-type: text/html X-Powered-By: PHP/4.3.5RC4-dev !#/usr/local/bin/php resource(1) of type (Socket) bool(true) resource(2) of type (Socket) bool(true) --snip-- Look like the four functions, "php_host_connect(***)", "php_network_getaddress(***)", "php_connect_nonb(***)" and "dump_stock_state(***)" wasn't reached and executed. I did open up the network.c and 27509-diff.txt with the editor and check to see if the patch was applied correctly and I can confirm that the patch was insteed applied. :-( ------------------------------------------------------------------------ [2004-03-10 18:42:19] pollita@php.net First off, thanks for being so patient and helpful. I'd like to ask you to apply a small patch which introduces several debug watchpoints. Then compile, run your test script, and post the results (they'll be a bit on the verbose side). http://169.229.135.175/test/27509-diff.txt ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
