Subject: php4: apache segfault w/ php4 and mysql,imap loaded together related to #165563

Date: Mon, 21 Oct 2002 00:53:04 -0700

Package: php4
Version: 4:4.2.3-3
Severity: normal


Hello,

Same situation as bug #165563 that was reported closed, I don't think the new
glibc ( the one i'm using 2.3.1-2 ) solved his problem, he probably deleted one
of the modules.

Same backtrace .. dies in strcmp, but works when only mysql is loaded or only
imap is loaded.

Of course it would be nice to load both :)

Regards,

If you downgrade libc6 to the previous version (or the version in
testing), your problems should go away.  This appears to be a libc6
partial upgrade bug.

The hypothesis about the #165563 bug is correct. I "forgot" to reinstall
php4-imap. Trying with php4-mysql, php4-imap getting segfault like
before.

Fortunately, I don't need php4-imap; but anyway ...

I don't reopen the bug, but can affirm the problem as expressed in
the present bug.

I also check the current php4, then I don't get any segv.
Still someone gets segv? I close this bug soon.

[Message part 1 (text/plain, inline)]

The php4-imap package is taunting me now.  No matter what I try, I am
not able to reproduce the segfault-on-startup bug with
apache+php4+php4-imap.  Can someone please confirm for me that they are
still able to reproduce this bug with libc6 2.3.1-3 on i386?

If it is still reproduceable, I'm going to need a LOT of information
about package versions in order to pin this down -- not just
dependencies, but every library loaded by apache at the time of the
crash.  Something's different between my system and yours...

Hello,

Well the box I had the problem on was running 2.2.19 and reiserfs, which
had worked well for a few years but decided to eat itself a few days
after reporting the bug.

It only appeared when mysql and imap modules for php were both loaded,
and only in apache, command line version was fine.

The box is now running woody ( ext3 now :> ), so I am unable to
reproduce.

Sorry.

Are you on i386?  If yes, I have a completely untested glibc packages
updated to recent CVS I'd like you to try (I want to make sure we're not
chasing a bug that's already fixed upstream).  Let me know and I'll send
you the link.

Subject: progress on the glibc 2.3 / php4 issues

Date: Sun, 15 Dec 2002 12:49:56 -0600

[Message part 1 (text/plain, inline)]

I've made some progress into figuring out the source of the glibc 2.3,
apache, php4, php4-imap segfaults.  I suspect that php4 and openssl are
ultimately at fault (at least, a change with regards to these two
packages seems to correct the error), but I'm not certain, so I'm 
sending a follow-up to the bug report to get feedback before reassigning
back to PHP4.

What I noticed in the startup behavior of Apache is that there are two
cycles of loading/unloading the Apache DSOs.  After loading the DSOs
once, Apache then unloads them (God knows why), and loads them again.
The unload (dlclose) also causes all DSO-specific dependency libs to be
unloaded -- with the singular exception of OpenSSL's libcrypto.  This
horrid library has probably been inadvertently referenced by Apache
itself, because it contains symbols with such original names as
'string_to_hex', 'crypt', and 'MD5_Init'.  Five to one says that 'crypt'
is the culprit somehow.

Now, it's entirely possible that the unloading of the library has
nothing at all to do with the final segfaults people have been
experiencing; at least, I haven't been able to figure out how glibc 2.3
would cause this problem if glibc 2.2 didn't.  Nevertheless, it did set
me on the path to a fix, as I tried to recompile libphp4.so without that
ridiculous OpenSSL dependency.

Adam, I don't know if you were aware of this (I was not), but upstream
has overloaded the meaning of the --with-ssl configure option such
that it not only controls whether OpenSSL should be used when linking
other extensions (e.g., snmp), it also enables an 'openssl' extension
that *can't be built as a shared extension*.  This means that the only
way to get rid of libphp4's dependency on libcrypto is to recompile it
without OpenSSL support -- which also means that the snmp extension
can't be built at the same time.  I want to discuss with you how to best
solve this packaging problem, both in the short term and in the long
term, before trying to upload any sort of a "hotfix".

Note, BTW, that just rebuilding php4 against glibc 2.3 does not fix the
problem. Only compiling it without OpenSSL support fixes the problem.

Michael, thank you for the use of your machine in tracking this down.
There is a libphp4.so binary that has been unceremoniously dropped in
your /usr/lib/apache/1.3/ directory which appears to do the trick as far
as getting Apache running.  Since it may still be a few weeks before
everything is sorted out in unstable, I hope this file might prove
useful to you in the meantime.

Michel, thank you also for your offer.  As you can see, it turned out to
be unnecessary, but if you would also like a copy of the fixed
libphp4.so binary (it's too raw yet to be distributed in a package), or
if you would like me to guide you through building a fixed local
php4 package, just let me know.

Wow.  If it does turn out to be a php4 problem, aj has told me that it's
okay to fill our conflicts lines with other packages so whoever winds up
with this bug, please make sure that debian-glibc@lists.debian.org knows
which version to conflict against.

Thanks for hacking this, Steve!
