From c18e68696fdd9fd293f051030bce5aaff3c9b185 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Mon, 14 Dec 2020 21:15:47 -0800 Subject: net/connector: Add const qualifier to cb_id MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The connector driver never modifies any cb_id passed to it, so add a const qualifier to those arguments so callers can declare their struct cb_id as a constant object. Fixes build warnings like these when passing a constant struct cb_id: warning: passing argument 1 of ‘cn_add_callback’ discards ‘const’ qualifier from pointer target Signed-off-by: Geoff Levand Link: https://lore.kernel.org/r/a9e49c9e-67fa-16e7-0a6b-72f6bd30c58a@infradead.org Signed-off-by: Jakub Kicinski --- include/linux/connector.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'include/linux') diff --git a/include/linux/connector.h b/include/linux/connector.h index cb732643471b..8ea860efea37 100644 --- a/include/linux/connector.h +++ b/include/linux/connector.h @@ -64,14 +64,14 @@ struct cn_dev { * @callback: connector's callback. * parameters are %cn_msg and the sender's credentials */ -int cn_add_callback(struct cb_id *id, const char *name, +int cn_add_callback(const struct cb_id *id, const char *name, void (*callback)(struct cn_msg *, struct netlink_skb_parms *)); /** * cn_del_callback() - Unregisters new callback with connector core. * * @id: unique connector's user identifier. */ -void cn_del_callback(struct cb_id *id); +void cn_del_callback(const struct cb_id *id); /** @@ -122,14 +122,14 @@ int cn_netlink_send_mult(struct cn_msg *msg, u16 len, u32 portid, u32 group, gfp int cn_netlink_send(struct cn_msg *msg, u32 portid, u32 group, gfp_t gfp_mask); int cn_queue_add_callback(struct cn_queue_dev *dev, const char *name, - struct cb_id *id, + const struct cb_id *id, void (*callback)(struct cn_msg *, struct netlink_skb_parms *)); -void cn_queue_del_callback(struct cn_queue_dev *dev, struct cb_id *id); +void cn_queue_del_callback(struct cn_queue_dev *dev, const struct cb_id *id); void cn_queue_release_callback(struct cn_callback_entry *); struct cn_queue_dev *cn_queue_alloc_dev(const char *name, struct sock *); void cn_queue_free_dev(struct cn_queue_dev *dev); -int cn_cb_equal(struct cb_id *, struct cb_id *); +int cn_cb_equal(const struct cb_id *, const struct cb_id *); #endif /* __CONNECTOR_H */ -- cgit v1.2.3 From 7061eb8cfa902daa1ec71d23b5cddb8b4391e72b Mon Sep 17 00:00:00 2001 From: Lijun Pan Date: Mon, 14 Dec 2020 15:19:28 -0600 Subject: net: core: introduce __netdev_notify_peers There are some use cases for netdev_notify_peers in the context when rtnl lock is already held. Introduce lockless version of netdev_notify_peers call to save the extra code to call call_netdevice_notifiers(NETDEV_NOTIFY_PEERS, dev); call_netdevice_notifiers(NETDEV_RESEND_IGMP, dev); After that, convert netdev_notify_peers to call the new helper.
