In testing this improved sysbench performance measurably by a couple of percentage points, especially if TLB-heavy security mitigations are active. This patch-set allows TLB flushes to be run concurrently: first request the remote CPUs to initiate the flush, then run it locally, and finally wait for the remote CPUs to finish their work. As of this release this is supported for X86 and ARM64.Ĭurrently, local and remote TLB flushes are not performed concurrently, which introduces unnecessary overhead - each INVLPG can take 100s of cycles. The feature is guarded with a static branch which avoids the overhead when disabled.

The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation. This release supports randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. Support for randomising the stack address offset in each syscall Recommended LWN article: Control-flow integrity for the kernelġ.3. CFI support for x86 is still under development, but is pretty close.

This feature has happily lived in Android kernels for almost 3 years. This release builds on last cycle's LTO work, and allows the arm64 kernels to be built with Clang's Control Flow Integrity feature, which is designed to abort the program upon detecting certain forms of undefined behavior that can potentially allow attackers to subvert the program’s control flow.

This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs

This enables to minimize this patch series and ease review. In this current form, Landlock misses some access-control features. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Because Landlock is a stackable LSM, it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. global filesystem access) for a set of processes. The goal of Landlock is to enable to restrict ambient rights (e.g. Landlock is a new Linux security module that allows to sandbox applications.
