Miller" , Jakub Kicinski , linux-kernel@vger.kernel.org Subject: [PATCH net-next v2 2/2] bonding: combine netlink and console error messages Date: Tue, 10 Aug 2021 22:53:31 -0400 Message-Id: In-Reply-To: References: MIME-Version: 1.0 X-Scanned-By: MIMEDefang 2.79 on 10.5.11.13 Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org X-Patchwork-Delegate: kuba@kernel.org There seems to be no reason to have different error messages between netlink and printk. It also cleans up the function slightly. Signed-off-by: Jonathan Toppins --- Notes: v2: - changed the printks to reduce object code slightly - emit a single error message based on if netlink or sysfs is attempting to enslave - rebase on top of net-next/master and convert additional instances added by XDP additions drivers/net/bonding/bond_main.c | 69 ++++++++++++++++++--------------- 1 file changed, 37 insertions(+), 32 deletions(-) diff --git a/drivers/net/bonding/bond_main.c b/drivers/net/bonding/bond_main.c index 365953e8013e..c0db4e2b2462 100644 --- a/drivers/net/bonding/bond_main.c +++ b/drivers/net/bonding/bond_main.c @@ -1725,6 +1725,20 @@ void bond_lower_state_changed(struct slave *slave) netdev_lower_state_changed(slave->dev, &info); } +#define BOND_NL_ERR(bond_dev, extack, errmsg) do { \ + if (extack) \ + NL_SET_ERR_MSG(extack, errmsg); \ + else \ + netdev_err(bond_dev, "Error: %s\n", errmsg); \ +} while (0) + +#define SLAVE_NL_ERR(bond_dev, slave_dev, extack, errmsg) do { \ + if (extack) \ + NL_SET_ERR_MSG(extack, errmsg); \ + else \ + slave_err(bond_dev, slave_dev, "Error: %s\n", errmsg); \ +} while (0) + /* enslave device to bond device */ int bond_enslave(struct net_device *bond_dev, struct net_device *slave_dev, struct netlink_ext_ack *extack) @@ -1738,9 +1752,8 @@ int bond_enslave(struct net_device *bond_dev, struct net_device *slave_dev, if (slave_dev->flags & IFF_MASTER && !netif_is_bond_master(slave_dev)) { - NL_SET_ERR_MSG(extack, "Device with IFF_MASTER cannot be enslaved"); - netdev_err(bond_dev, - "Error: Device with IFF_MASTER cannot be enslaved\n"); + BOND_NL_ERR(bond_dev, extack, + "Device with IFF_MASTER cannot be enslaved"); return -EPERM; } @@ -1752,15 +1765,13 @@ int bond_enslave(struct net_device *bond_dev, struct net_device *slave_dev, /* already in-use? */ if (netdev_is_rx_handler_busy(slave_dev)) { - NL_SET_ERR_MSG(extack, "Device is in use and cannot be enslaved"); - slave_err(bond_dev, slave_dev, - "Error: Device is in use and cannot be enslaved\n"); + SLAVE_NL_ERR(bond_dev, slave_dev, extack, + "Device is in use and cannot be enslaved"); return -EBUSY; } if (bond_dev == slave_dev) { - NL_SET_ERR_MSG(extack, "Cannot enslave bond to itself."); - netdev_err(bond_dev, "cannot enslave bond to itself.\n"); + BOND_NL_ERR(bond_dev, extack, "Cannot enslave bond to itself."); return -EPERM; } @@ -1769,8 +1780,8 @@ int bond_enslave(struct net_device *bond_dev, struct net_device *slave_dev, if (slave_dev->features & NETIF_F_VLAN_CHALLENGED) { slave_dbg(bond_dev, slave_dev, "is NETIF_F_VLAN_CHALLENGED\n"); if (vlan_uses_dev(bond_dev)) { - NL_SET_ERR_MSG(extack, "Can not enslave VLAN challenged device to VLAN enabled bond"); - slave_err(bond_dev, slave_dev, "Error: cannot enslave VLAN challenged slave on VLAN enabled bond\n"); + SLAVE_NL_ERR(bond_dev, slave_dev, extack, + "Can not enslave VLAN challenged device to VLAN enabled bond"); return -EPERM; } else { slave_warn(bond_dev, slave_dev, "enslaved VLAN challenged slave.
