Subject: [PATCH] batman-adv: Avoid storing non-TT-sync flags on singular entries too
|
|
|
|
Since commit 382d020fe3fa ("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: 382d020fe3fa ("batman-adv: fix TT sync flag inconsistencies")
