http://issues.apache.org/bugzilla/show_bug.cgi?id=39498 ------- Additional Comments From [EMAIL PROTECTED] 2006-05-07 23:17 ------- What I'm driving at is that configure makes a blind assumption that if SO_ACCEPTFILTER is defined, that it is available in the system, which is not the case. To be available, it either needs to be (1) manually loaded via kldload, or (2) loaded at boot time by having the administrator modify loader.conf, or (3) recompile the kernel and have it static within. At configure time, prior to compilation of http source, the configure script could first check for SO_ACCEPTFILTER, then if it is defined, emit a small c program, compile, and observe the result to determine if it is REALLY available. Such a program as found below seems to make this determination. I ran it on one machine that had accf_http.ko loaded, and it ran with exit of 0, that is it was able to set the accept filter. Running on another machine that had the kernel module, but not loaded, resulted in the failure of setsockopt() with an errno of 2, which is the very thing that is being observed. It is my belief that there are many people out there that compile up the code and expect it to work without emission of warnings. This kind of check at source compile time would clean this up. It could make a comment to the user attempting to compile httpd, that the option would be available, but is being turned off unless either the re-configure with the kernel module already loaded or forced via configure option. /* Debugging of Failed to enable the '%s' Accept Filter is defined in server/listen.c the call is to apr_socket_accept_filter() defined in srclib/apr/network_io/unix/sockopt.c */ #include <sys/types.h> #include <sys/module.h> #include <sys/socket.h> #include <sys/socketvar.h> #include <netinet/in.h> #include <errno.h> main () { int sock; sock = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP ); if (sock < 0) { printf( "socket(): failed: errno: %d\n", errno ); exit( -1 ); } struct sockaddr_in saddr; bzero( &saddr, sizeof (saddr)); saddr.sin_family = AF_INET; saddr.sin_addr.s_addr = htonl( INADDR_ANY ); saddr.sin_port = 6543; if ( bind( sock, (struct sockaddr *) &saddr, sizeof(saddr)) ) { printf( "bind(): failed: errno: %d\n", errno ); exit( -1 ); } if ( listen( sock, 5 )) { printf( "listen(): failed: errno: %d\n", errno ); exit( -1 ); } struct accept_filter_arg af; bzero( &af, sizeof (af) ); strncpy( af.af_name, "httpready", 16 ); if ((setsockopt( sock, SOL_SOCKET, SO_ACCEPTFILTER, &af, sizeof (af) )) < 0) { printf( "setsocketopt(): failed: errno: %d\n", errno ); exit( -1 ); } exit( 0 ); } -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
