Hi!
We got someone complaining about using MKL in a SELinux-enabled docker due to TEXTREL in shared lib.
And seems IMPI also has this issue.
Any idea why? Is this a bug during the build process of Intel's libraries?

Here is the first time we hear about this case. BTW we never check this OS. you may check the MKL System Requirements. Recently, not exactly the same, but a similar issue has been discussed at the IPP forum - https://software.intel.com/en-us/forums/intel-integrated-performance-primitives/topic/841949.
How does this problem prevent to use mkl with your application?

What do you mean by "this OS"? It's on both Ubuntu/CentOS.
Just in case, SELinux is a rule-based whitelist library for security, which comes with most of the popular Linux distros these days.
By default (i.e. stock selinux policy provided by distro/docker's repo), when use in docker with selinux enabled, libraries under /usr (where we ship our library and embedded mkl to) is forced to a "selinux context" different than host filesystem, and under this context TEXTREL is not allowed for security consideration. SELinux will give application a "permission denied" error.

We confirmed the problem on the mkl side and will investigate the cause of this issue.

Please check the latest version of MKL 2020 update 4 which has been released the last Friday and let us know the results.
