Pull x86/pti update from Thomas Gleixner: "Just a single change from the anti-performance departement: - Add a new PR_SPEC_DISABLE_NOEXEC option which allows to apply the speculation protections on a process without inheriting the state on exec. This remedies a situation where a Java-launcher has speculation protections enabled because that's the default for JVMs which causes the launched regular harmless processes to inherit the protection state which results in unintended performance degradation" * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/speculation: Add PR_SPEC_DISABLE_NOEXEC

libbpf: add support for using AF_XDP sockets

2019-02-25T22:21:42+00:00

This commit adds AF_XDP support to libbpf. The main reason for this is to facilitate writing applications that use AF_XDP by offering higher-level APIs that hide many of the details of the AF_XDP uapi. This is in the same vein as libbpf facilitates XDP adoption by offering easy-to-use higher level interfaces of XDP functionality. Hopefully this will facilitate adoption of AF_XDP, make applications using it simpler and smaller, and finally also make it possible for applications to benefit from optimizations in the AF_XDP user space access code. Previously, people just copied and pasted the code from the sample application into their application, which is not desirable. The interface is composed of two parts: * Low-level access interface to the four rings and the packet * High-level control plane interface for creating and setting up umems and af_xdp sockets as well as a simple XDP program.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S. Miller
