While reviewing the fixes submitted to batman-adv in the recent weeks, further problems in similar or adjecent code was identified. This was either noticed in the manual review or reported by sashiko.dev.
Especially in the TT code, you have the global and the local translation table. But when a bug was fixed, often only one of the two codepaths was fixed. It was now tried to sync the TVLV preparation code between to of them - not style wise but fixes wise. Besides the hardening, it will also make the code less confusing.
The BLA and TP fixes are just some reference counting fixes - either reference leak fixes or missing reference handling.
