Subject: [PATCH] ebtables: Fix for broken chain renaming
|
|
|
|
Loading extensions pollutes 'errno' value, hence before using it to
|
|
indicate failure it should be sanitized. This was done by the called
|
|
function before the parsing/netlink split and not migrated by accident.
|
|
Move it into calling code to clarify the connection.
|
|
|
|
Fixes: a7f1e208cdf9c ("nft: split parsing from netlink commands")
|
|
Signed-off-by: Phil Sutter <phil@nwl.cc>
|
|
(cherry picked from commit 55b7c71dce7144f4dc0297c17abf0f04879ee247)
