#23942 [Opn->Bgs]: 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 +Status: Bogus Bug Type: Apache2 related Operating System: Linux PHP Version: 4.3.2 New Comment: updating the uw-imap client and the php build options with the latest one from gentoo solved the problem. don't know what it was really related to, it is really difficult for me to track it down dut to the large amount of combinations of packages and related options. it was probaly related to a wrong set of compile options and/or a combo of compile options and obsolete libraries with had problems with ssl. please consider the bug one "closed" or "invalid". if in the near future i'll find out more data about it i'll report it here. thanks for your help alessandro Previous Comments: ------------------------------------------------------------------------ [2003-06-16 01:58:19] alextxm at tin dot it sniper: I think there still is something related to PHP itself. On both the three machine using the same version of mysql (with openssl support enabled), openssl and php with apache 1.3.x have no problem at all. Also, both apache1 and apache2 without php work fine with mysql+ssl. Problem is somehow related to the apache2 sapi in php...maybe it is not php own fault but there is a weird relation between them. let me know if I can help with more tests and/or providing more info. alessandro ------------------------------------------------------------------------ [2003-06-15 16:51:37] sniper@php.net Yes, just what I expected. It's not really our problem, most likely mysql does some fancy init stuff with openssl, or you just mix two different openssl versions. Try compiling everything from sources with debug symbols, I guess mysql and openssl have some --enable-debug switch too. Then you'll get better GDB backtrace. ------------------------------------------------------------------------ [2003-06-15 14:14:22] alextxm at tin dot it 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 ------------------------------------------------------------------------ [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? :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
