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

ID: 23942 User updated by: alextxm at tin dot it Reported By: alextxm at tin dot it Status: Open Bug Type: Apache2 related Operating System: Linux PHP Version: 4.3.2 New Comment: more news: i've jsut tried recompiling mysql without openssl support on both the gentoo platforms (as of RH9, cfr ldd output in my previous comment) and php now work as expected with --with-mysql=/usr. So the whole things seems to be related to openssl support in MySQL. Is still the whole thing pertinent to php or should I ask mysql people ? alessandro Previous Comments: ------------------------------------------------------------------------ [2003-06-15 13:56:18] alextxm at tin dot it output of ldd libmysqlclient.so for each platform (cfr. my previous comment) : rh9) libz.so.1 => /usr/lib/libz.so.1 (0x40053000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x40061000) libnsl.so.1 => /lib/libnsl.so.1 (0x4008e000) libm.so.6 => /lib/tls/libm.so.6 (0x400a4000) libc.so.6 => /lib/tls/libc.so.6 (0x42000000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) gentoo 1.2) libz.so.1 => /usr/lib/libz.so.1 (0x40047000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x40055000) libnsl.so.1 => /lib/libnsl.so.1 (0x40082000) libm.so.6 => /lib/libm.so.6 (0x40097000) libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x400b8000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x400e6000) libc.so.6 => /lib/libc.so.6 (0x401d9000) libdl.so.2 => /lib/libdl.so.2 (0x402fc000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) gentoo 1.4) libz.so.1 => /usr/lib/libz.so.1 (0x40052000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x40060000) libnsl.so.1 => /lib/libnsl.so.1 (0x4008d000) libm.so.6 => /lib/libm.so.6 (0x400a1000) libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x400c3000) libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x400f1000) libc.so.6 => /lib/libc.so.6 (0x401b1000) libdl.so.2 => /lib/libdl.so.2 (0x402da000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000) i'm also investigating more things... let me know if you need to me to test some specific items alessandro ------------------------------------------------------------------------ [2003-06-14 17:19:25] sniper@php.net That sounds odd. And as you're not running Apache2 as threaded (worker, or whatever that MPM was again), it shouldn't be thread-safety issue either. Could you check what libmysqlclient.so is linked with on those systems? Output of: # ldd libmysqlclient.so And FYI: the bundled mysql library is far from obsolete. (it works, doesn't it? :) ------------------------------------------------------------------------ [2003-06-14 15:40:21] alextxm at tin dot it finally, i've found the problem: compiling php 4.3.2 with --with-mysql=/path-to-mysql staically linked is the culprit. The problem can be avoided using --with-mysql and so using PHP's built-in (but obsolete) mysql interface or using: --with-mysql=shared,/path-to-mysql and then enabling php_mysql.so in php.ini Tests had been accomplished on three machines: a) gentoo linux 1.2: glibc 2.2.5, php 4.3.2, apache 2.0.45/46, mysql 4.0.12, openssl 0.9.6j b) gentoo linux 1.4rc4: glibc 2.3.1, php 4.3.2, apache 2.0.46, mysql 4.0.13, openssl 0.9.7b c) redhat 9: php 4.2.2, apache 2.0.40, openssl 0.9.7a, mysql-4.0.10 alessandro ------------------------------------------------------------------------ [2003-06-14 08:02:41] alextxm at tin dot it i'm doing some more tests... an interesting thing: on Redhat 9.0 it works fine (openssl 0.9.7a, php 4.2.2, apache 2.0.40 - both stock versions) . I'm trying to figure out where the problem is. I'll let you know, probaly there is something in my setup which causes php or apache to behave strangely. alessandro ------------------------------------------------------------------------ [2003-06-11 11:28:03] sniper@php.net Try reduce the configure options to the bare minimum first. Then if you don't get any segfaults, try every excluded option one by one to see which one is causing this. And for the backtrace you just need to keep pressing 'enter' until it gets there..the first couple of screens gdb is loading the symbols from every linked library, you can ignore it.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
