From 836b2fe544a5e9b5ce116622cb36fba33838c6fd Mon Sep 17 00:00:00 2001 From: Eduard Zingerman Date: Fri, 4 Sep 2026 01:33:23 -0700 Subject: selftests/bpf: Check that JMP32 pointer vs zero jumps are not predicted Add jmp32_ptr_vs_zero_jne: the fall-through of the 32-bit compare, which the verifier used to skip, contains an out of bounds map value access, hence w/o the previous patch the program is accepted. See previous patch for detailed description.

In addition to supporting a variety of features + expected in a traditional hardware switch, it enables fine-grained + programmatic extension and flow-based control of the network. This + control is useful in a wide variety of applications but is + particularly important in multi-server virtualization deployments, + which are often characterized by highly dynamic endpoints and the + need to maintain logical abstractions for multiple tenants. + + The Open vSwitch datapath provides an in-kernel fast path for packet + forwarding. It is complemented by a userspace daemon, ovs-vswitchd, + which is able to accept configuration from a variety of sources and + translate it into packet processing rules. + + See http://openvswitch.org for more information and userspace + utilities. + + To compile this code as a module, choose M here: the module will be + called openvswitch. + + If unsure, say N. -- cgit v1.3.1
