haproxy crash when updating ca and certificate files #3165
Description
Detailed Description of the Problem
Hello
I attempted to update the root CA and certificates at runtime through the CLI while HAProxy was running, as follows.
When updating the rootca file and certificate file via the CLI using runtimeAPI, HAProxy crashes. However, if only the rootca file (ca file) is updated, no crash occurs. But, after updating the ca file, when the certificate file is updated (whether it's the same certificate or a newly generated one), HAProxy crashes. This crash occurs even when no messages are being received from the outside.
If this crash is caused by an issue with the test sequence, could you please provide guidance on how to proceed with the testing? If it is a latent issue, I hope the attached script and backtrace will be helpful in making the necessary corrections.
Expected Behavior
If it is not possible to update the certificate, it would be preferable for HAProxy to output an error message and not perform the update, rather than crashing.
Steps to Reproduce the Behavior
The test was conducted as follows:
I opened a terminal and executed the command './haproxy -V -f haproxy.cfg' to start HAProxy.
In another terminal, I ran a script to update the certificates.
The script that caused the crash updates the root CA file (ca.crt), waits for 1 second, and then updates the certificates.
For the first scenario, the same certificate was updated without any changes. For the second scenario, a new certificate was generated and then updated.
Each scenario was executed independently, and in both cases, a crash occurred.
The script for the first scenario is as follows:
