2018-01-25sfc: only advertise TX timestamping if we have the license for itMartin Habets
We check the license for TX hardware timestamping capability. The PTP probe will have enabled PTP sync events from the adapter. If later, at TX queue init, it turns out we do not have the license, we don't need the sync events either.

2018-01-25sfc: use main datapath for HW timestamps if availableMartin Habets
We can now transmit SKBs in 2 ways: 1. Via the MC (for the 7XXX series and earlier), using efx_ptp_xmit_skb_mc(). 2. Via the TX queues on the dedicated PTP channel (8XXX series and later), using efx_ptp_xmit_skb_queue(). The PTP worker thread uses the method set up at probe time. It never checked the return code from the old efx_ptp_xmit_skb(), so it now returns void. We increment the TX dropped counter of the device if the transmit fails. As a result of the probe per channel the remove gets called multiple times. Clean up efx->ptp_data properly to avoid the 2nd call blowing up.

2018-01-25sfc: handle TX timestamps in the normal data pathMartin Habets
Before this work, TX timestamping is done by sending each SKB to the MC. On the 8000 series (Medford1) we have high speed timestamping via the MAC, which means we can use normal TX queues for this without a significant drop in bandwidth. On the X2000 series (Medford2) support for transmitting via the MC is removed, so the new way must be used. This patch enables timestamping on a TX queue, if requested. It also enhances TX event handling to process the extra completion events, and puts the time in the SKB.

2018-01-25net: Move net:netns_ids destruction out of rtnl_lock() and document locking ↵Kirill Tkhai
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().

2018-01-25net: tcp: close sock if net namespace is exitingDan Streetman
When a tcp socket is closed, if it detects that its net namespace is exiting, close immediately and do not wait for FIN sequence. For normal sockets, a reference is taken to their net namespace, so it will never exit while the socket is open. However, kernel sockets do not take a reference to their net namespace, so it may begin exiting while the kernel socket is still open. In this case if the kernel socket is a tcp socket, it will stay open trying to complete its close sequence. The sock's dst(s) hold a reference to their interface, which are all transferred to the namespace's loopback interface when the real interfaces are taken down. When the namespace tries to take down its loopback interface, it hangs waiting for all references to the loopback interface to release, which results in messages like: unregister_netdevice: waiting for lo to become free. Usage count = 1 These messages continue until the socket finally times out and closes. Since the net namespace cleanup holds the net_mutex while calling its registered pernet callbacks, any new net namespace initialization is blocked until the current net namespace finishes exiting. After this change, the tcp socket notices the exiting net namespace, and closes immediately, releasing its dst(s) and their reference to the loopback interface, which lets the net namespace continue exiting.

2018-01-25wil6210: fix random failure to bring network interface upLior David
Currently when we want to bring the interface up, we first reset the device which causes the boot loader to run. Then we halt the device CPU, load FW image and resume the device CPU. There are some boot loader versions which perform redundant memory accesses even when idle. Halting the device CPU while boot loader access memory can cause the device memory controller to get stuck, the FW will fail to load and the network interface will not come up. For such boot loaders implement a workaround where we freeze the boot loader before halting the device CPU, so it will not perform any memory accesses.

2018-01-24net: separate SIOCGIFCONF handling from dev_ioctl()Al Viro
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>

Alex fixes MACVLAN offload for fm10k, where we were not seeing unicast packets being received because we did not correctly configure the default VLAN ID for the port and defaulting to 0. Jake cleans up unnecessary parenthesis in a couple of "if" statements. Fixed the driver to stop adding VLAN 0 into the VLAN table, since it would cause the VLAN table to be inconsistent between the PF and VF. Also fixed an issue where we were assuming that VLAN 1 is enabled when the default VLAN ID is not set, so resolve by not requesting any filters for the default_vid if it has not yet been assigned. Ngai fixes an issue which was generating a dmesg regarding unbale to kill a particular VLAN ID for the device. This is due to ndo_vlan_rx_kill_vid() exits with an error and the handler for this ndo is fm10k_update_vid() which exits prematurely under PF VLAN management. So to resolve, we must check the VLAN update action type before exiting fm10k_update_vid(), and act appropriately based on the action type.
