6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
[ Upstream commit a7d5a955bfa854ac6b0c53aaf933394b4e6139e4 ]
destroy element command bogusly reports ENOENT in case a set element
does not exist. ENOENT errors are skipped, however, err is still set
and propagated to userspace.
# nft destroy element ip raw BLACKLIST { 1.2.3.4 }
Error: Could not process rule: No such file or directory
destroy element ip raw BLACKLIST { 1.2.3.4 }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
