-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
To reproduce the bug, start from a vanilla Debian server, install apache2,
libapache2-mod-perl2 and libxml-libxml-perl.
Create a perl file handler.pl with following content :
#!/usr/bin/perl
use XML::LibXML;
$[;
1;
Add a directive to /etc/apache2/apache2.conf (or add a file in
/etc/apache2/conf-enabled with the same directive) :
PerlRequire "/path/to/handler.pl"
Apache will crash on startup.
===========
I did an in-depth investigation of this problem. Here is what happens:
apache goes through 3 stages on startup : pre-config, destroy-config,
create-config
In the pre-config stage, all modules are loaded
loading mod_perl.so also brings libperl.so and libm.so in the program map
XML::LibXML is a XS package that has a dependency on libstc++.so =>
LibXML.so and libstdc++.so.6 are brought in the program map
libstdc++.so has a dependency on libm.so
libm.so has a relocation dependency on libperl.so (this is strange but true).
=> a 'dependency cluster' is created between libstdc++, libm and libperl.
The special $[ variable is implemented in the XS library arybase.so, it
installs an op checker via wrap_op_checker() in the perl interpreter (see
perl-5.24.1: ext/arybase/arybase.xs BOOT section)
The address of the op checker is saved in the static PL_check array that
resides in libperl.so
The op checker itself resides in arybase.so
Installing an op checker is a one-way operation, Perl provides no API to
remove it.
At the end of pre-config stage we have an informal dependency
libperl.so(PL_check) -> arybase.so
During the destroy-config stage, apache unloads all the modules.
For mod_perl this implies removing all XS modules (see
libapache2-mod-perl2-2.0.10:
src/modules/perl/modperl_interp.c:modperl_interp_destroy())
At this stage the op checker in PL_check points to invalid memory as
arybase.so was unloaded!
Then apache removes mod_perl itself (see apr-1.5.2:
dso/unix/dso.c:dso_cleanup())
Normally, this would also remove libperl.so and libm.so but with the
dependency cluster that was created with libstc++, libperl is not removed!
During create-config stage, mod_perl is reloaded but not libperl of course.
loading arybase.so is differed until the PerlRequire directive is executed
=> PL_check points to invalid memory.
The first thing mod_perl does is load /etc/perl/sitecustomize.pl => it
crashes on the first op involving the corrupted op checked.
This bug is similar to bug #905603 : a pointer to invalid memory is kept in
memory after config-destroy.
==================
The fix that I proposed for bug #905603 will work here too: the crash is
avoided by skipping the unloading the XS modules:
--- a/src/modules/perl/modperl_interp.c 2018-08-03 20:49:54.000000000 +0200
+++ b/src/modules/perl/modperl_interp.c 2018-08-03 20:49:54.000000000 +0200
@@ -122,11 +122,11 @@
MP_TRACE_i(MP_FUNC, "*error - still in use!*");
}
- handles = modperl_xs_dl_handles_get(aTHX);
+ /*handles = modperl_xs_dl_handles_get(aTHX);*/
modperl_perl_destruct(interp->perl);
- modperl_xs_dl_handles_close(handles);
+ /*modperl_xs_dl_handles_close(handles);*/
free(interp);
}
An ideal solution would be that the faulty XS modules do proper cleanup on
unloading but Perl does not make it simpler (no API to remove a op checker).
