From 6b5ca133b9fbd57f0ca4acd7999c4e9a93e702be Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Fri, 24 Jan 2020 14:21:14 +0000 Subject: bpf: update jmp32 test cases to fix range bound deduction From: Daniel Borkmann [ no upstream commit ] Since commit f2d67fec0b43 ("bpf: Undo incorrect __reg_bound_offset32 handling") has been backported to stable, we also need to update related test cases that started to (expectedly) fail on stable. Given the functionality has been reverted we need to move the result to REJECT.
