+Subject: netfilter: nf_tables: report use refcount overflow
+To: netfilter-devel@vger.kernel.org
+Cc: gregkh@linuxfoundation.org, stable@vger.kernel.org, sashal@kernel.org
+Message-ID: <20230812220941.56747-2-pablo@netfilter.org>
+
+From: Pablo Neira Ayuso <pablo@netfilter.org>
+
+commit 1689f25924ada8fe14a4a82c38925d04994c7142 upstream.
+
+Overflow use refcount checks are not complete.
+
+Add helper function to deal with object reference counter tracking.
+Report -EMFILE in case UINT_MAX is reached.
+
+nft_use_dec() splats in case that reference counter underflows,
+which should not ever happen.
+
+Add nft_use_inc_restore() and nft_use_dec_restore() which are used
+to restore reference counter from error and abort paths.
+
+Use u32 in nft_flowtable and nft_object since helper functions cannot
+work on bitfields.
+
+Remove the few early incomplete checks now that the helper functions
+are in place and used to check for refcount overflow.
+
+Fixes: 96518518cc41 ("netfilter: add nftables")
