From c5e58d88054178092a1c5fc77f3c2b7c3b614902 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Fri, 24 Jan 2020 14:21:14 +0000 Subject: [PATCH] bpf: update jmp32 test cases to fix range bound deduction [ 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.
