From 6d365eabce3c018a80f6e0379b17df2abb17405e Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 6 Sep 2023 17:22:58 +0200 Subject: [PATCH] netfilter: nft_set_pipapo: stop GC iteration if GC transaction allocation fails nft_trans_gc_queue_sync() enqueues the GC transaction and it allocates a new one. If this allocation fails, then stop this GC sync run and retry later.
