2015-11-17dl2k: Add support for IP1000A-based cardsOndrej Zary3-6/+69
Add support for IP1000A chips to dl2k driver. IP1000A chip looks like a TC9020 with integrated PHY. This allows IP1000A chips to work reliably because the ipg driver is buggy - it loses packets under load and then completely stops transmitting data. Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps: vendor=0x13f0 device=0x1023 (rev 0x41) subsystem vendor=0x1043 device=0x8180 MAC address registers access needed to be changed from 8-bit to 16-bit because 8-bit does not work on IP1000A. 8-bit access is not even allowed in the TC9020 datasheet (although it worked). 16-bit access works on both. Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably a rebranded TC9020): vendor=0x1186 device=0x4000 (rev 0x0c) subsystem vendor=0x1186 device=0x4000 Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: David S.

2015-11-17net/core: use netdev name in warning if no parentBjørn Mork1-5/+8
A recent flaw in the netdev feature setting resulted in warnings like this one from VLAN interfaces: WARNING: CPU: 1 PID: 4975 at net/core/dev.c:2419 skb_warn_bad_offload+0xbc/0xcb() : caps=(0x00000000001b5820, 0x00000000001b5829) len=2782 data_len=0 gso_size=1348 gso_type=16 ip_summed=3 The ":" is supposed to be preceded by a driver name, but in this case it is an empty string since the device has no parent. There are many types of network devices without a parent. The anonymous warnings for these devices can be hard to debug. Log the network device name instead in these cases to assist further debugging. This is mostly similar to how __netdev_printk() handles orphan devices.

2015-11-16af_unix: don't append consumed skbs to sk_receive_queueHannes Frederic Sowa1-0/+1
In case multiple writes to a unix stream socket race we could end up in a situation where we pre-allocate a new skb for use in unix_stream_sendpage but have to free it again in the locked section because another skb has been appended meanwhile, which we must use. Accidentally we didn't clear the pointer after consuming it and so we touched freed memory while appending it to the sk_receive_queue. So, clear the pointer after consuming the skb.

2015-11-16ip_tunnel: disable preemption when updating per-cpu tstatsJason A. Donenfeld2-2/+4
Drivers like vxlan use the recently introduced udp_tunnel_xmit_skb/udp_tunnel6_xmit_skb APIs. udp_tunnel6_xmit_skb makes use of ip6tunnel_xmit, and ip6tunnel_xmit, after sending the packet, updates the struct stats using the usual u64_stats_update_begin/end calls on this_cpu_ptr(dev->tstats). udp_tunnel_xmit_skb makes use of iptunnel_xmit, which doesn't touch tstats, so drivers like vxlan, immediately after, call iptunnel_xmit_stats, which does the same thing - calls u64_stats_update_begin/end on this_cpu_ptr(dev->tstats). While vxlan is probably fine (I don't know?), calling a similar function from, say, an unbound workqueue, on a fully preemptable kernel causes real issues: [ 188.434537] BUG: using smp_processor_id() in preemptible [00000000] code: kworker/u8:0/6 [ 188.435579] caller is debug_smp_processor_id+0x17/0x20 [ 188.435583] CPU: 0 PID: 6 Comm: kworker/u8:0 Not tainted 4.2.6 #2 [ 188.435607] Call Trace: [ 188.435611] [<ffffffff8234e936>] dump_stack+0x4f/0x7b [ 188.435615] [<ffffffff81915f3d>] check_preemption_disabled+0x19d/0x1c0 [ 188.435619] [<ffffffff81915f77>] debug_smp_processor_id+0x17/0x20 The solution would be to protect the whole this_cpu_ptr(dev->tstats)/u64_stats_update_begin/end blocks with disabling preemption and then reenabling it.

The first patch removes the poll_link as mv88e6xxx. The 3 following patches fixes the setup in regards of the datasheet. The 2 last patches introduces a clean header and replaces all magic values. v2: cleanup InitReady patch, add missing Acked-by and fix header copyright notice ==================== Signed-off-by: David S.

To align with the mv88e6xxx code, use the register defines to access all the register addresses and bit fields. Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: David S. Miller <davem@davemloft.net>

To align with the mv88e6xxx code, add a similar header file with all the register defines. The file is based on the mv88e6xxx header for coherency.

2015-11-16net: dsa: mv88e6060: use the correct bit shift for mac0Neil Armstrong1-1/+2
According to the mv88e6060 datasheet, the first mac byte must be at position 9 instead of 8 since the bit 8 is used to select if the mac address must differ for each port for Pause frames. Use the correct shift and set the same mac address for all port. Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: David S.

As of mv88e6xxx remove the poll_link callback since the link state change polling is now handled by the phylib. Tested on a mv88e6060 B0 device with a TI DM816X SoC.

2015-11-16net/mlx4_core: Fix sleeping while holding spinlock at rem_slave_countersEran Ben Elisha1-12/+27
When cleaning slave's counter resources, we hold a spinlock that protects the slave's counters list. As part of the clean, we call __mlx4_clear_if_stat which calls mlx4_alloc_cmd_mailbox which is a sleepable function. In order to fix this issue, hold the spinlock, and copy all counter indices into a temporary array, and release the spinlock. Afterwards, iterate over this array and free every counter. Repeat this scenario until the original list is empty (a new counter might have been added while releasing the counters from the temporary array).

2015-11-16net/mlx5e: Use the right DMA free function on TX pathAchiad Shochat2-32/+43
On xmit path we use skb_frag_dma_map() which is using dma_map_page(), while upon completion we dma-unmap the skb fragments using dma_unmap_single() rather than dma_unmap_page(). To fix this, we now save the dma map type on xmit path and use this info to call the right dma unmap method upon TX completion.
