From 82ccfb488eeac5507471099b9b4e6d136cc06e3b Mon Sep 17 00:00:00 2001 From: Jacek Tomasiak Date: Mon, 19 Jun 2023 13:46:36 +0200 Subject: iptables: Fix handling of non-existent chains Since 694612adf87 the "compatibility" check considers non-existent chains as "incompatible". This broke some scripts which used calls like `iptables -L CHAIN404` to test for chain existence and expect "No chain/target/match by that name." in the output. This patch changes the logic of `nft_is_table_compatible()` to report non-existent chains as "compatible" which restores the old behavior. Fixes: 694612adf87 ("nft: Fix selective chain compatibility checks") Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1648 Signed-off-by: Jacek Tomasiak Signed-off-by: Jacek Tomasiak Signed-off-by: Phil Sutter --- iptables/tests/shell/testcases/iptables/0004-return-codes_0 | 1 + 1 file changed, 1 insertion(+) (limited to 'iptables/tests/shell') diff --git a/iptables/tests/shell/testcases/iptables/0004-return-codes_0 b/iptables/tests/shell/testcases/iptables/0004-return-codes_0 index 33c5f1f3..234f3040 100755 --- a/iptables/tests/shell/testcases/iptables/0004-return-codes_0 +++ b/iptables/tests/shell/testcases/iptables/0004-return-codes_0 @@ -58,6 +58,7 @@ cmd 1 "$ENOENT" -Z bar cmd 0 -E foo bar cmd 1 "$EEXIST_F" -E foo bar cmd 1 "$ENOENT" -E foo bar2 +cmd 1 "$ENOENT" -L foo cmd 0 -N foo2 cmd 1 "$EEXIST_F" -E foo2 bar -- cgit v1.2.3
