* net: Move net:netns_ids destruction out of rtnl_lock() and document locking ↵Kirill Tkhai2018-01-251-18/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scheme Currently, we unhash a dying net from netns_ids lists under rtnl_lock(). It's a leftover from the time when net::netns_ids was introduced. There was no net::nsid_lock, and rtnl_lock() was mostly need to order modification of alive nets nsid idr, i.e. for: for_each_net(tmp) { ... id = __peernet2id(tmp, net); idr_remove(&tmp->netns_ids, id); ... } Since we have net::nsid_lock, the modifications are protected by this local lock, and now we may introduce better scheme of netns_ids destruction. Let's look at the functions peernet2id_alloc() and get_net_ns_by_id(). Previous commits taught these functions to work well with dying net acquired from rtnl unlocked lists. And they are the only functions which can hash a net to netns_ids or obtain from there. And as easy to check, other netns_ids operating functions works with id, not with net pointers. So, we do not need rtnl_lock to synchronize cleanup_net() with all them. The another property, which is used in the patch, is that net is unhashed from net_namespace_list in the only place and by the only process. So, we avoid excess rcu_read_lock() or rtnl_lock(), when we'are iterating over the list in unhash_nsid(). All the above makes possible to keep rtnl_lock() locked only for net->list deletion, and completely avoid it for netns_ids unhashing and destruction. As these two doings may take long time (e.g., memory allocation to send skb), the patch should positively act on the scalability and signify decrease the time, which rtnl_lock() is held in cleanup_net().

| * kill dev_ifsioc()Al Viro2018-01-241-38/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Once upon a time net/socket.c:dev_ifsioc() used to handle SIOCSHWTSTAMP and SIOCSIFMAP. These have different native and compat layout, so the format conversion had been needed. In 2009 these two cases had been taken out, turning the rest into a convoluted way to calling sock_do_ioctl(). We copy compat structure into native one, call sock_do_ioctl() on that and copy the result back for the in/out ioctls. No layout transformation anywhere, so we might as well just call sock_do_ioctl() and skip all the headache with copying. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only two of dev_ioctl() callers may pass SIOCGIFCONF to it. Separating that codepath from the rest of dev_ioctl() allows both to simplify dev_ioctl() itself (all other cases work with struct ifreq *) *and* seriously simplify the compat side of that beast: all it takes is passing to inet_gifconf() an extra argument - the size of individual records (sizeof(struct ifreq) or sizeof(struct compat_ifreq)). With dev_ifconf() called directly from sock_do_ioctl()/compat_dev_ifconf() that's easy to arrange. As the result, compat side of SIOCGIFCONF doesn't need any allocations, copy_in_user() back and forth, etc. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to prevent sk_user_data being overwritten. The check is done under the callback lock. This should prevent a socket from being attached twice to a KCM mux.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It takes 1sec for bond link down notification to hit user-space when all slaves of the bond go down. 1sec is too long for protocol daemons in user-space relying on bond notification to recover (eg: multichassis lag implementations in user-space). Since the link event code already marks team device port link events as urgent, this patch moves the code to cover all lag ports and master.

* | | net: dsa: Support internal phy on 'cpu' portSebastian Reichel2018-01-234-32/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for enabling the internal PHY for a 'cpu' port. It has been tested on GE B850v3, B650v3 and B450v3, which have a built-in MV88E6240 switch hardwired to a PCIe based network card. On these machines the internal PHY of the i210 network card and the Marvell switch are connected to each other and must be enabled for properly using the switch. While the i210 PHY will be enabled when the network interface is enabled, the switch's port is not exposed as network interface. Additionally the mv88e6xxx driver resets the chip during probe, so the PHY is disabled without this patch.

The 'out' label is removed so we just return ERR_PTR(-EINVAL) directly. Signed-off-by: David S. Miller <davem@davemloft.net>
