Linux 6.6 Released

01 Nov 2023 tags: audit selinux

Linux v6.6 was released on Monday, October 30th. I already wrote up a post highlighting the SELinux and audit changes that were submitted during the merge window, however there were additional changes that went in during the release candidate process which are described below.

SELinux

• Fix a bug that would prevent NFS submounts before the SELinux policy was loaded. This was noticeable on systems that attempted to mount a NFS filesystem in their initramfs and would often result in the following error message on the system’s console: “SELinux: Unable to set superblock options before the security server is initialized”.

Audit

• Fix a problem where performing file open operations in io_uring could result in a reference count race condition that would result in a kernel panic in the audit pathname logging code.

• Improve the netfilter / nf_tables audit logging by properly logging the NFT_MSG_GETOBJ_RESET and NFT_MSG_GETRULE_RESET commands.

In addition to my highlights, LWN.net provides a nice overall summary of the kernel changes made during the first and second weeks of the merge window.
