http://issues.apache.org/bugzilla/show_bug.cgi?id=32085 httpd segfaults when called from apachectl and LD_PRELOAD is used. Summary: httpd segfaults when called from apachectl and LD_PRELOAD is used. Product: Apache httpd-2.0 Version: 2.0.52 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Core AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Red Hat Enterprise ES 3 Apache 2.0.52 compiled with the following configuration: CFLAGS="-O3" ./configure \ --prefix=/usr/local/apache2 \ --enable-ssl \ --enable-so \ --enable-rewrite=shared \ --enable-expires \ --enable-info \ --enable-deflate \ --enable-ldap \ --enable-auth-ldap \ --with-ldap \ --with-ssl=/usr PHP 4.3.8 is compiled as a DSL and has Oracle 10g client libraries linked in. I have the following in my envvars file: export ORACLE_SID=dpndb export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=/u01/app/oracle/product/10.1.0/client_1 export TNS_ADMIN=/u01/app/oracle/product/10.1.0/client_1/network/admin export TWO_TASK=/u01/app/oracle/product/10.1.0/client_1/network/admin export NLS_LANG="English_America.WE8ISO8859P1" export LD_LIBRARY_PATH="$ORACLE_HOME/lib:/usr/local/apache2/lib:$LD_LIBRARY_PATH" export LD_PRELOAD=/u01/app/oracle/product/10.1.0/client_1/lib/libclntsh.so.10.1 This setup works great until I attempt to add LDAP authentication support. Here is the test addition I have made to my httpd.conf file: LDAPSharedCacheSize 200000 LDAPCacheEntries 1024 LDAPCacheTTL 600 LDAPOpCacheEntries 1024 LDAPOpCacheTTL 600 <Location /ldap-status> SetHandler ldap-status Order deny,allow Deny from all Allow from digitalpath.net AuthType basic AuthName "LDAP Login" AuthLDAPEnabled on AuthLDAPURL "ldap://hostname.net/dc=ldap,dc=domain,dc=net?uid"; AuthLDAPAuthoritative on require valid-user </Location> When I attempt to do anything from apachectl (start, stop, configtest), I get the following: [EMAIL PROTECTED] bin]# ./apachectl configtest ./apachectl: line 99: 18206 Segmentation fault $HTTPD -t If I run httpd -t by itself from the prompt, I get "Syntax OK". If I bypass the apachectl script completely and stop my httpd server with httpd -k stop and start it up again with httpd -k start -DSSL everything works properly, including the mod_auth_ldap authentication. As soon as I remove the above LDAP configuration entries from httpd.conf, apachectl once again works correctly. However! If I leave the LDAP configuration in my httpd.conf as it is listed above, edit my envvars file and remove the LD_PRELOAD line, apachectl does *not* segfault and I can once again use it to manage my httpd process. Perhaps there is something I do not understand about LD_PRELOAD ... but it seems odd that apachectl (or httpd to be exact) Segfaults because of the combination of it and the LDAP config options in httpd.conf. I have tried adding /usr/lib/libldap.so.2 to my LD_PRELOAD line to no avail. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
