netfilter: nf_tables: validate all pending tables
We have to validate all tables in the transaction that are in VALIDATE_DO state, the blamed commit below did not move the break statement to its right location so we only validate one table. Moreover, we can't init table->validate to _SKIP when a table object is allocated. If we do, then if a transcaction creates a new table and then fails the transaction, nfnetlink will loop and nft will hang until user cancels the command. Add back the pernet state as a place to stash the last state encountered. This is either _DO (we hit an error during commit validation) or _SKIP (transaction passed all checks). Fixes: 00c320f9b755 ("netfilter: nf_tables: make validation state per table") Reported-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Florian Westphal <fw@strlen.de>
