RPM Install Fails on FIPS Mode Systems

[ChrisLeinbach]

Thanks in advance for your bug report!

• Have you reproduced issue in safe mode?
• Have you used the debugging guide to try to resolve the issue?
• Have you checked our FAQs to make sure your question isn't answered there?
• Have you checked to make sure your issue does not already exist?
• Have you checked you are on the latest release of Pulsar?

What happened?

The Pulsar RPM packages fail to install on systems that have FIPS mode enabled when installing via both the RPM and DNF/Yum commands.

This happens due to MD5 digests being the default digest method for RPM but MD5, being non-FIPS compliant, is blocked on FIPS enabled systems.

Pulsar version

1.117.0

Which OS does this happen on?

🐧 Red Hat based (Fedora, Alma, RockyLinux, CentOS Stream, etc.)

OS details

AlmaLinux 9.4

Which CPU architecture are you running this on?

x86_64/AMD64

What steps are needed to reproduce this?

1. Enable FIPS mode on your system using the fips=1 kernel command line argument.
2. Attempt to install the Pulsar RPM with either DNF/Yum or RPM directly.
3. DNF/Yum will give a very generic error. RPM will error stating that the digest for the Electron license file digest failed.

Additional Information:

See Elastic Beats #23670 for a similar issue and how it was fixed for that project.

Building a virtual machine to test out the build and install now. Will create pull request if successful.

This appears to be more nuanced that I originally thought. I was able to build an RPM with my change but both my build and the one i pulled from the releases page have SHA256 digests.

The result of signature/digest checking both RPMs:

# rpm --checksig -v ./*pulsar*.rpm 
./Linux.pulsar-1.117.0.x86_64.rpm:
    Header SHA256 digest: OK
    Header SHA1 digest: OK
    Payload SHA256 digest: OK
./pulsar-1.117.0-dev.x86_64.rpm:
    Header SHA256 digest: OK
    Header SHA1 digest: OK
    Payload SHA256 digest: OK

The result of trying to install the 1.117.0 release RPM:

# rpm -i Linux.pulsar-1.117.0.x86_64.rpm 
error: unpacking of archive failed on file /opt/Pulsar/LICENSE.electron.txt;6659d276: cpio: Digest mismatch
error: pulsar-1.117.0-1.x86_64: install failed

Its almost like something in the release binary pipeline is mangling that license file or its digest.
