Subject: [iptables PATCH 00/13] Extensions: Review xlate callbacks
Date: Wed, 23 Nov 2022 17:43:37 +0100	[thread overview]
Message-ID: <20221123164350.10502-1-phil@nwl.cc> (raw)

This is a review of all extensions' xlate callbacks focussing on
correctness of operation and return code.

Patches 1 and 2 address ebtables mark target.
Patches 3, 4, 6 and 9 add 'return 0' calls in more or less unlikely
cases.
Patch 5 fixes multiple problems in CONNMARK target.
Patches 7, 8 and 10 extend some translations.
The last three patches add comments to help future reviewers asserting
code correctness.

Phil Sutter (13):
