#23942 [Opn->Fbk]: php 4.3.x causes apache2+mod_ssl to sigsev on client authentication

ID: 23942 Updated by: sniper@php.net Reported By: alextxm at tin dot it -Status: Open +Status: Feedback Bug Type: Apache2 related Operating System: Linux PHP Version: 4.3.2 New Comment: Your configure line contains couple of options that are really unnecessary, for example these: -with-db (use --enable-dba) --enable-versioning (Only needed if you have php3 installed too and that doesn't support Apache2, so..) --enable-track-vars (doesn't exist), --enable-inline-optimization (might cause problems) --without-readline (not enabled by default anyway) --disable-posix-threads (why?) --enable-force-cgi-redirect (Only used for CGI build) --enable-discard-path (Only used for CGI builds) And what MPM is used for Apache2? Remove those options mentioned above + --enable-debug and try again. ("rm -f config.cache" first!) If it still crashes, provide the backtrace. Previous Comments: ------------------------------------------------------------------------ [2003-06-02 03:51:19] alextxm at tin dot it yes i'm sure they use the same openssl library since i've complied both openssl, apache2 and php from source. configure for mod_php (php as apache DSO module) : ./configure --without-readline --with-pam --with-openssl -with-gdbm=/usr --with-mysql=/usr --with-gd=/usr --with-pspell --with-tiff-dir=/usr --with-jpeg-dir=/usr --with-pdflib=/usr --with-ttf --with-t1lib --with-zlib --with-zlib-dir=/usr/lib --with-exec-dir=/usr/bin --with-apxs2=/usr/sbin/apxs2 --with-imap --with-imap-ssl --with-mcrypt --with-mhash --disable-posix-threads --with-java=/opt/sun-jdk-1.4.1.02 --prefix=/usr --with-bz2 --enable-ftp --enable-force-cgi-redirect --enable-discard-path --enable-mime-magic --enable-wddx --enable-dbase --with-zlib=yes --with-iconv --enable-bcmath --enable-sysvsem --enable-exif --enable-sysvshm --enable-sockets --enable-calendar --enable-trans-sid --enable-safe-mode --enable-versioning --enable-track-vars --enable-inline-optimization --with-config-file-path=/etc/php4 --with-sablot=/usr --enable-xslt --with-xslt-sablot --with-xmlrpc --with-gettext -with-db=/usr ------------------------------------------------------------------------ [2003-06-01 20:34:37] sniper@php.net What was the configure line used to configure PHP? And are you sure you're linking both apache2 and PHP with _same_ SSL libs? ------------------------------------------------------------------------ [2003-06-01 17:35:22] alextxm at tin dot it i'm going to rebuild php with --enable-debug and to try to get some backtraces. btw, please note that the no php scripts are actually involved in this scenario: the website i'm testing it on has no php script. I simply try to access an area (with plain html pages) which requires me to have a SSL Client Certificate; authentication (and so, access) happens only if apache2 (i'm using 2.0.46) is started without -D PHP4 otherwise authentication fails and the apache error log file only says: "[Mon Jun 02 00:15:54 2003] [notice] child pid 16784 exit signal Segmentation fault (11)" ------------------------------------------------------------------------ [2003-06-01 17:24:41] derick@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2003-06-01 17:19:09] alextxm at tin dot it Client authentication with a SSL certificate work fine in apache2 until php4 is loaded as a module. trying to access an area granted only with a client-certificate based authentication with php4 enabled as module will cause Apache2 to sigsev (Segmentation Fault) in the related child process(es). Disabling php4 will cause the problem to disappear, so I guess it really is a php related problem. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23942&edit=1
