[PATCH net 3/3] netfilter: nf_tables: fix bidirectional offload regression

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Felix Fietkau <nbd@xxxxxxxx>

Commit 8f84780b84d6 ("netfilter: flowtable: allow unidirectional rules")
made unidirectional flow offload possible, while completely ignoring (and
breaking) bidirectional flow offload for nftables.
Add the missing flag that was left out as an exercise for the reader :)
