Hi,

Does CentOS monitor the linux mainline to backport bug fixes? or does it monitor RedHat patch releases? or both? Incase it only monitors RedHat patch releases, does redhat make all their security bug fixes publicly available for the CentOS community to adopt or does it selectively release patches?

CentOS is a rebuild of the sources released by Red Hat for its Red Hat Enterprise Linux. Basically the flow goes something like this

[Red Hat] -> [git.centos.org] -> [CentOS rebuilders] -> [CentOS mirrors]

For information on how and what Red Hat makes public, I would check with what they have on their website versus basing on what a person on a mailing list says. That said, Red Hat makes the fixes they deliver to customers available via the above method.

Just wanted to make a note on the centosplus kernel.

While the distro kernel is a strict rebuild of the RHEL kernel, CentOS also provides a custom kernel (called kernel-plus in C7 and C8). It can freely accommodate bug fixes (patches) and added features.

For example, you can see the actual patches for CentOS-7 here:

https://git.centos.org/rpms/kernel/blob/c7-sig-centosplus-kernel/f/SOURCES

A request for a new patch/feature can be filed at http://bugs.centos.org for consideration.
