Linux 6.19 Released

With Linux v6.19 being released on Sunday, February 8th, this post is much later than usual. However, there were only a few small LSM and SELinux changes beyond what was mentioned in my post about the merge window changes, the highlights are below.

LSM

• The LSM initialization rework merged during the Linux v6.19 merge window introduced a regression causing the procfs file “/proc/sys/vm/mmap_min_addr” to disppear when CONFIG_SECURITY was not enabled at compile time. The final release of Linux v6.19 fixes this problem by ensuring that the “/proc/sys/vm/mmap_min_addr” is present regardless of the CONFIG_SECURITY configuration.

• There were a number of small changes made to securityfs as part of a much larger VFS effort. These changes were focused on implementation improvements and should no result in any user visible changes.

SELinux

• Much like the securityfs chanes mentioned above, there were a number of similar, small changes made to selinuxfs. Once again, none of these changes should be visible to users.
