Date: Wed, 29 Nov 2023 16:23:04 -0800 Message-ID: <20231130002309.1322111-3-gerickson@nuovations.com> X-Mailer: git-send-email 2.42.0 In-Reply-To: <20231130002309.1322111-1-gerickson@nuovations.com> References: <20231130002309.1322111-1-gerickson@nuovations.com> Precedence: bulk X-Mailing-List: connman@lists.linux.dev List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Scanned-By: mailmunge 3.11 on 209.68.5.112 This optimizes the conditional '&&' clauses in '__connman_connection_gateway_remove' to take advantage of stored, local state in 'set_default[46]' thereby avoiding redundant checks of 'do_ipv[46]', 'data->ipv[46]_config', and 'data->ipv[46]_config->vpn'. In '__connman_connection_gateway_remove', local variables 'set_default[46]' are set to reflect the state of 'do_ipv[46] && data->ipv[46]_config' as well as that of 'data->ipv[46]_config->vpn', effectively forming a three-conditional '&&'. Then, shortly thereafter, with no intervening mutations of 'data', 'do_ipv[46]', 'data->ipv[46]_config', and 'data->ipv[46]_config->vpn' are checked again, along with 'data->index >= 0', in a four-conditional '&&'. Since the first three of those checks are redundant and simply reflect the state of 'set_default[46]', three of those four conditional '&&' terms can simply be replaced with 'set_default[46]'. This change makes that replacement. --- src/connection.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/src/connection.c b/src/connection.c index b5349834c813..647631e54324 100644 --- a/src/connection.c +++ b/src/connection.c @@ -1640,13 +1640,11 @@ void __connman_connection_gateway_remove(struct connman_service *service, /* If necessary, delete any VPN-related host routes. */ - if (do_ipv4 && data->ipv4_config && - data->ipv4_config->vpn && data->index >= 0) + if (set_default4 && data->index >= 0) connman_inet_del_host_route(data->ipv4_config->vpn_phy_index, data->ipv4_config->gateway); - if (do_ipv6 && data->ipv6_config && - data->ipv6_config->vpn && data->index >= 0) + if (set_default6 && data->index >= 0) connman_inet_del_ipv6_host_route( data->ipv6_config->vpn_phy_index, data->ipv6_config->gateway);
