From c1a9d47b59d02f466ead8c023f6822f68285edbe Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Thu, 18 Apr 2024 17:27:32 +0200 Subject: [PATCH] selftests: netfilter: nft_zones_many.sh: move to lib.sh infra Also do shellcheck cleanups here, no functional changes intended. When running tests via vng tool, the packetpath insertion test fails: dd: failed to open '/dev/stdout': Device or resource busy Just omit 'of=' and this will work as intended.
