Segmentation Fault #2

Closed HumorlessJester closed 5 years ago

HumorlessJester commented 5 years ago

First, let me start with thank you for picking up this dead project.

I was able to download the package and install it, but when I include the created pam.so file in my INI I then get a Segmentation Fault when running PHP. Per gdb the fault is in the zen_collect_module_handlers:

0x00000000008074e1 in zend_collect_module_handlers () at /usr/local/src/php-7.2.1/Zend/zend_API.c:1973 1973 ZEND_HASH_FOREACH_PTR(CG(class_table), ce) {

I am only running 2 extensions currently, pam.so and pthreads.so. Pthreads was working previously, and when I remove pam.so the Segmentation Fault disappears.

I'm willing to assist in troubleshooting, but I don't know where to go from here.

I have no idea about ZEND internals but lets try it out.

What happens if you dont use pthreads.so? Does pam.so still crash php? Have you tried with php 7.3?

Can you also try with previous release 2.1.0 instead of 2.1.1? https://github.com/amishmm/php-pam/releases/tag/v2.1.0

Sample code which you can try to run: (change username and password, change login to pam service name if necessary)

<?php
if (extension_loaded('pam')) {
    if (!pam_auth("username", 'password', $error, true, 'login')) {
        echo "fail: $error\n";
    }
    else {
        echo "pass: $error\n";
    }
}
else {
    echo "pam.so not loaded\n";
}

Any update? Else I will close the issue after waiting 2 more weeks.
