Subject: [PATCH 4.9 68/90] batman-adv: Avoid storing non-TT-sync flags on singular entries too
Date: Thu, 19 Mar 2020 14:00:30 +0100	[thread overview]
Message-ID: <20200319123949.592169931@linuxfoundation.org> (raw)
In-Reply-To: <20200319123928.635114118@linuxfoundation.org>

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=UTF-8, Size: 1325 bytes --]

From: Linus Lüssing <linus.luessing@c0d3.blue>

commit 4a519b83da16927fb98fd32b0f598e639d1f1859 upstream.

Since commit 54e22f265e87 ("batman-adv: fix TT sync flag inconsistencies")
TT sync flags and TT non-sync'd flags are supposed to be stored
separately.

The previous patch missed to apply this separation on a TT entry with
only a single TT orig entry.

This is a minor fix because with only a single TT orig entry the DDoS
issue the former patch solves does not apply.

Fixes: 54e22f265e87 ("batman-adv: fix TT sync flag inconsistencies")
